(29) Further, the first anchor part 20 according to this embodiment is woven by a needle loom because the pattern 14 is not formed therein.
(30) Next, an example of a fabric weave of each of the main body part 10 and the first anchor part 20 according to this embodiment will be described by using
(31) Further, the pile yarn 1b forming the loop face 10d (the loop face 21) configures a fabric weave by repeating 6-2-2-2 float-sink with respect to the weft 2 (the weft ground yarn 2a and the fusion yarn 2b), in which the pile yarn 1b floats so as to pass on the upper side with respect to six pieces of wefts 2 (weft ground yarns 2a and fusion yarns 2b) adjacent to each other, sinks so as to pass on the lower side with respect to two pieces of wefts 2 (weft ground yarns 2a and fusion yarns 2b) adjacent to each other, floats so as to pass on the upper side with respect to two pieces of wefts 2 (weft ground yarns 2a and fusion yarns 2b) adjacent to each other, and sinks so as to pass on the lower side with respect to two pieces of wefts 2 (weft ground yarns 2a and fusion yarns 2b) adjacent to each other, as shown in
(32) Further, the elastic yarn 1c forming the loop face 10d (the loop face 21) configures a fabric weave by repeating 1-1 float-sink with respect to the weft 2 (the weft ground yarn 2a and the fusion yarn 2b), in which the elastic yarn 1c floats so as to pass on the upper side with respect to a single piece of weft 2 (weft ground yarn 2a and fusion yarn 2b) and sinks so as to pass on the lower side with respect to a single piece of weft 2 (weft ground yarn 2a and fusion yarn 2b), as shown in

(34) Subsequently, an example of a fabric weave of the pattern 14 which is formed in the main body part 10 according to this embodiment will be described by using
(35) Further, the pile yarn 1b forming the pattern 14 configures a fabric weave by repeating 2-2 float-sink with respect to the weft 2 (the weft ground yarn 2a and the fusion yarn 2b), in which the pile yarn 1b sinks so as to pass on the lower side with respect to two pieces of wefts 2 (weft ground yarns 2a and fusion yarns 2b) adjacent to each other and floats so as to pass on the upper side with respect to two pieces of wefts 2 (weft ground yarns 2a and fusion yarns 2b) adjacent to each other, as shown in
(36) Further, the elastic yarn 1c forming the pattern 14 configures a fabric weave by repeating 1-1 float-sink with respect to the weft 2 (the weft ground yarn 2a and the fusion yarn 2b), in which the elastic yarn 1c floats so as to pass on the upper side with respect to a single piece of weft 2 (weft ground yarn 2a and fusion yarn 2b) and sinks so as to pass on the lower side with respect to a single piece of weft 2 (weft ground yarn 2a and fusion yarn 2b), as shown in
(37) In addition, the fabric weave composed of the warp ground yarn 1a, the pile yarn 1b, and the elastic yarn 1c shown in
(38) Further, in each of the main body part 10 and the first anchor part 20, it is possible to freely adjust the maximum elongation in the warp direction (the longitudinal direction L) by the quality of the materials of the warp 1 and the weft 2 (in particular, the thicknesses of the elastic yarn 1c and the weft ground yarn 2a) and the number of times of picking (the number) of the weft 2. In the present invention, the maximum elongation refers to the percentage of the difference between the longest length (an elongation dimension) when having been stretched with the highest load and the original length (a lay-flat size) with respect to the original length.
(39) In particular, from the results of the overall determination of a sensory evaluation which will be described later, it is preferable that the maximum elongation in the warp direction (the longitudinal direction L) of the main body part 10 according to this embodiment is set to be in a range of 40% to 80%, and a range of 45% to 75% is more preferable, and the most preferred is 60%.
(40) Further, it is preferable that the maximum elongation in the warp direction (the longitudinal direction L) of the first anchor part 20 according to this embodiment is greater than the maximum elongation in the warp direction (the longitudinal direction L) of the main body part 10.
(41) In this manner, in the knee joint bandage 100, the maximum elongation in the warp direction (the longitudinal direction L) of the first anchor part 20 is greater than the maximum elongation in the warp direction (the longitudinal direction L) of the main body part 10, whereby it is possible to reduce a burden on the knee joint by improving the stability of the knee joint by fixing the knee joint by a tightening force of the main body part 10 while suppressing a fastening force of the first anchor part 20 on the thigh of a wearer (without causing a feeling of discomfort of the wearer due to constriction of a blood flow of the thigh).
(42) Here, an embodiment in which the maximum elongation of the main body part 10 is set to be 60% and the maximum elongation of the first anchor part 20 is set to be 80% will be described. With respect to the warp ground yarn 1a of the main body part 10 according to this embodiment, a woolly nylon two-fold yarn having a thickness of 100 counts is preferable, and in the main body part 10 according to this embodiment, it is preferable to use 132 pieces of woolly nylon two-fold yarns.

(48) That is, in the main body part 10 according to this embodiment, for example, if a width is 5 cm, warp density by the warps 1 (the warp ground yarns 1a, the pile yarns 1b, and the elastic yarns 1c) is 1485.6D/mm(=((210D132 pieces)+(100D2 pieces132 pieces)+(560D36 pieces))/50 mm).
(49) Further, in the first anchor part 20 according to this embodiment, for example, if a width is 8 cm, warp density by the warps 1 (the warp ground yarns 1a, the pile yarns 1b, and the elastic yarns 1c) is 1581.5D/mm(=((210D200 pieces)+(100D2 pieces200 pieces)+(840D53 pieces))/80 mm).
(50) Further, in the pile yarn 1b of each of the main body part 10 and the first anchor part 20 according to this embodiment, a filament count is 10 pieces, whereby there is an advantage that, compared to a case where a filament count is a low count (for example, 7 pieces), an adhesive force between dense filaments is high and a feel of the fabric (each of the main body part 10 and the first anchor part 20) is soft.
(51) Further, the elastic yarn 1c of the main body part 10 according to this embodiment has a thickness of 560 deniers, thereby making the thickness of the fabric (the main body part 10) thin, compared to the case of a thick elastic yarn (for example, 1120 deniers), and thus it is possible to soften the fabric itself.

(57) Further, in the first anchor part 20 according to this embodiment, a single piece of weft ground yarn 2a and a single piece of fusion yarn 2b are simultaneously picked as the weft 2 by a power loom, and the number of times of picking (the number) of the weft 2 (the weft ground yarn 2a and the fusion yarn 2b) is 30.8 times (each 30.8 pieces) per 2.54 cm (1 inch).
(58) That is, in the main body part 10 in the quality of material and the number of times of picking (the number) of the weft 2 described above, weft density by the wefts 2 (the polyester woolly yarns and the nylon thermal fusion yarns) is 9225D/inch(=(150D+100D)36.9 times/inch).
(59) Further, in the first anchor part 20 in the quality of material and the number of times of picking (the number) of the weft 2 described above, weft density by the wefts 2 (the polyester woolly yarns and the nylon thermal fusion yarns) is 7700D/inch(=(150D+100D)30.8 times/inch).
(60) Further, the weft ground yarn 2a of the weft 2 of each of the main body part 10 and the first anchor part 20 according to this embodiment has a thickness of 150 deniers, whereby it is possible to make the thickness of the fabric (each of the main body part 10 and the first anchor part 20) thin, compared to the case of a weft ground yarn (for example, 300 deniers) which is a thick weft.
(61) In this manner, in the main body part 10 according to this embodiment, due to the quality of the materials of the warp 1 and the weft 2 (in particular, the thicknesses of the elastic yarn 1c and the weft ground yarn 2a) described above and the number of times of picking (the number) of the weft 2 described above, it is possible to set the maximum elongation in the warp direction (the longitudinal direction L) to be 60%.
(62) Further, in the first anchor part 20 according to this embodiment, due to the quality of the materials of the warp 1 and the weft 2 (in particular, the thicknesses of the elastic yarn 1c and the weft ground yarn 2a) described above and the number of times of picking (the number) of the weft 2 described above, it is possible to set the maximum elongation in the warp direction (the longitudinal direction L) to be 80%.
(63) Further, with respect to the thickness of the elastic yarn 1c according to this embodiment, 560 deniers has been given as an example. However, in the present invention, available (mass-producible) 420 deniers which is a thickness lower by 1 rank, or 1120 deniers which is a thickness higher by 1 rank may be selected, and the thickness and the number of times of picking (the number) of the weft 2 described above may be changed. That is, if the thickness of the elastic yarn 1c according to this embodiment is in a range of 420 deniers to 1120 deniers, it is possible to set the maximum elongation in the warp direction of the main body part 10 to be the maximum elongation within the above-described range. Further, it is also possible to set the maximum elongation in the warp direction of the first anchor part 20 to be the maximum elongation within a desired range.
(64) Further, with respect to the thickness of the weft ground yarn 2a of the weft 2 according to this embodiment, 150 deniers has been given as an example. However, in the present invention, available (mass-producible) 100 deniers which is a thickness lower by 1 rank, or 300 deniers which is a thickness higher by 1 rank may be selected, and the thickness of the elastic yarn 1c and the number of times of picking (the number) of the weft 2 described above may be changed. That is, if the thickness of the weft ground yarn 2a of the weft 2 according to this embodiment is in a range of 100 deniers to 300 deniers, it is possible to set the maximum elongation in the warp direction of the main body part 10 to be the maximum elongation within the above-described range. Further, it is also possible to set the maximum elongation in the warp direction of the first anchor part 20 to be the maximum elongation within a desired range.
(65) Further, with respect to the number of times of picking (the number) of the weft 2 (the weft ground yarn 2a and the fusion yarn 2b) according to this embodiment, 36.9 times (each 36.9 pieces) per 2.54 cm (1 inch) has been given as an example. However, in the present invention, the number of times of picking (the number) of the weft 2 (the weft ground yarn 2a and the fusion yarn 2b) in a range of 32.8 times (each 32.8 pieces) per 2.54 cm to 41.0 times (each 41.0 pieces) per 2.54 cm may be selected, and the thicknesses of the elastic yarn 1c and the weft 2 described above may be changed. That is, if the number of times of picking (the number) of the weft 2 (the weft ground yarn 2a and the fusion yarn 2b) according to this embodiment is in a range of 32.8 times (each 32.8 pieces) per 2.54 cm to 41.0 times (each 41.0 pieces) per 2.54 cm, it is possible to set the maximum elongation in the warp direction of the main body part 10 to be the maximum elongation within the above-described range. Further, it is also possible to set the maximum elongation in the warp direction of the first anchor part 20 to be the maximum elongation within a desired range.
(66) Further, in a case where the thickness of the main body part 10 is too thick, when winding the bandage around the lower leg of a wearer, it becomes bulky, and thus it becomes difficult to wind it, and in a case where the thickness of the main body part 10 is too thin, the fabric itself of the bandage is easily foldable, and thus a desired fixing force is not obtained. For this reason, it is preferable that the thickness of the main body part 10 is set to be a thickness in which it is easy to wind the bandage and a desired fixing force is obtained, and for example, if the maximum elongation in the warp direction (the longitudinal direction L) of the main body part 10 is 60%, it is preferable to set the thickness of the main body part 10 to be less than or equal to 3 mm.
(67) Further, in a case where the thickness of the first anchor part 20 is too thick, when fastening the first anchor part 20 around the thigh of a wearer, it becomes bulky, and thus it becomes difficult to wind it, and in a case where the thickness of the first anchor part 20 is too thin, the fabric itself of the bandage is easily foldable, and thus a desired fastening force is not obtained. For this reason, it is preferable that the thickness of the first anchor part 20 is set to be a thickness in which it is easy to fasten the first anchor part 20 around the thigh of a wearer and a desired fastening force is obtained, and if the maximum elongation in the warp direction (the longitudinal direction L) of the first anchor part 20 is 80%, it is preferable to set the thickness of the first anchor part 20 to be less than or equal to 4 mm.
(68) Further, in the first anchor part 20 according to this embodiment, the loops (the loop face 21) are provided on a face (the front ground face) which becomes the outside in a case where the first anchor part 20 is fastened around the thigh of a wearer, and therefore, a second engaging part 40 (a hook face 43) provided at the first anchor part 20 is provided on the back ground face side of one end 20a or the other end 20b of the first anchor part 20 in terms of the ease of attachment and detachment and the degree of freedom of an engaging position.
(69) Similarly, the first engaging part 30 (the hook face 33) provided at the main body part 10 is provided on the back ground face side of the other end 10b of the main body part 10 in terms of the ease of attachment and detachment and the degree of freedom of an engaging position.
(70) Further, in the main body part 10, in order to configure a crossing portion below the knee and a lower anchor, the lengths of portions (the first supporting part 12 and the second supporting part 13) which cross each other below the knee of a wearer, and the length of a portion (the winding part 11) which circles around the lower leg of the wearer at least once are required, and although there is an individual difference in the circumference of the knee or the thickness of the lower leg according to gender, age, or the like, it is conceivable that the length of the main body part 10 is set to in a range of 68 cm to 88 cm, for example. Further, in the main body part 10, a certain level of width is required in order to effectively perform the fixing of the knee joint of the wearer, and it is preferable to set the width to be 5 cm, for example.
(71) Further, the main body part 10 according to this embodiment is woven in a fabric having the loop face 10d of a touch fastener. However, if the maximum elongation in the warp direction (the longitudinal direction L) is a desired maximum elongation, the loop face 10d of a touch fastener is not necessarily required.
(72) However, the main body part 10 is woven in a fabric having the loop face 10d of a touch fastener, whereby compared to a case where it does not have the loop face 10d, when being in non-use, it is possible to compactly store the knee joint bandage 100 by rolling it and making the hook face 33 of the first engaging part 30 be engaged with the loop face 10d of the main body part 10, and depending on a wearer, there is also a case of using the knee joint bandage 100 with the hook face 33 of the first engaging part 30 be engaged with the main body part 10, and thus a degree of freedom can be provided in a use method (an engaging position) of the knee joint bandage 100.
(73) Furthermore, in the first anchor part 20 according to this embodiment, the second engaging part 40 having the hook face 43 of a touch fastener, which is detachably stuck to the loop face 21 of the first anchor part 20, is provided on the back ground face side of one end 20a or the other end 20b (in
(74) Further, in the first anchor part 20 according to this embodiment, in order to circle around the thigh of a wearer, it is preferable that, for example, the length of a band-shaped body is set in a range of 34 cm to 38 cm.
(75) Further, if the fastening forces on the thigh and the lower leg of a wearer by the first anchor part 20 and the main body part 10 (the winding part 11) are too strong, constriction of a blood flow occurs in the thigh and the lower leg, causing a feeling of discomfort to the wearer. In particular, the feeling of discomfort is remarkable in the thigh, compared to the lower leg.
(76) For this reason, in the knee joint bandage 100 according to this embodiment, a feeling of discomfort to a wearer is alleviated by dispersing pressure, which is applied to the body surface of the wearer by the first anchor part 20, by widening the area of the first anchor part 20 which comes into contact with the body surface, relative to the main body part 10 (the winding part 11).
(77) That is, it is preferable that the width of the first anchor part 20 according to this embodiment is set to be wider than the width of the main body part 10 and be in a range of 6 cm to 8 cm, for example.
(78) Further, the first anchor part 20 and the main body part 10 according to this embodiment are joined to each other with an angle between the longitudinal direction L of the first anchor part 20 and the longitudinal direction L of the main body part 10 being 120, as shown in
(79) Further, in a case of pulling the main body part 10 from one end 10a to the other end 10b side, the closer the angle is to 180, the more a force acts in the longitudinal direction L of the first anchor part 20, whereby the first anchor part 20 rotates, and the closer the angle is to 90, the more a force acts in the width direction W of the first anchor part 20, whereby the first anchor part 20 rides up along the lower side of the thigh. For this reason, it is preferable that the range of the angle is set to be in a range of 110 to 130 in consideration of the ease of a use method of the knee joint bandage 100 such that in a case of pulling the main body part 10 from one end 10a to the other end 10b side, the main body part 10 can be pulled diagonally downward with respect to the first anchor part 20 in a state where floating does not occur in the first anchor part 20 and the main body part 10 is not twisted in the vicinity of a joining portion 50.
(80) Further, the joining portion 50 between the first anchor part 20 and one end 10a of the main body part 10 is joined at a position where a distance from one end 20a or the other end 20b (in
(81) In particular, in the knee joint bandage 100 according to this embodiment, as shown in
(82) In this way, in a case where the knee joint bandage 100 has been worn, an engaging position of the hooks (the hook face 43) of the second engaging part 40 with the loops (the loop face 21) of the first anchor part 20 and an engaging position of the hooks (the hook face 33) of the first engaging part 30 with the loops (the loop face 21) of the first anchor part 20 do not overlap, and thus it is possible to prevent a decrease in engaging force due to overlapping of the hooks (the hook face 33) of the first engaging part 30 and the second engaging part 40.
(83) Further, the joining portion 50 between the first anchor part 20 and one end 10a of the main body part 10 is sewn convexly to the other end 10b side of the main body part 10 so as to become longer than the length in the width direction W of the main body part 10.
(84) In this manner, in the knee joint bandage 100, the joining portion 50 is sewn in a shape convex toward the other end 10b side of the main body part 10, whereby in a case of winding the knee joint bandage 100 around the knee joint of a wearer, a twist at the joining portion 50 can be absorbed in response to the winding (pulling) direction of the main body part 10 and the occurrence of floating or wrinkles in the vicinity of the joining portion 50 can be suppressed.
(85) Further, in a case where the joining portion 50 is formed in a substantially triangular shape, when a wearer wears the knee joint bandage 100, stress is concentrated on the vertex of the triangle due to the tensile stress from the main body part 10, and the cloth of the vertex portion is weakened, and thus there is a concern that the sewn place may collapse.
(86) For this reason, the joining portion 50 according to this embodiment is formed in a substantially semicircular shape, whereby stress does not concentrate even with respect to the tensile stress from the main body part 10, the collapse of the sewn place can be prevented, it is also possible to cope with an individual differences in the pulling direction of the main body part 10, and it is possible to suppress the occurrence of floating or wrinkles in the vicinity of the joining portion 50.
(87) Further, in the joining between the first anchor part 20 and one end 10a of the main body part 10, sewing is not performed on both sides of the main body part 10, whereby both sides of the main body part 10 are not fixed to the first anchor part 20 and the fabrics in both sides in the vicinity of the joining portion 50 of the main body part 10 can be extended.
(88) For this reason, in the knee joint bandage 100 according to this embodiment, even if a winding angle of the main body part 10 with respect to the lower leg of a wearer changes somewhat, distortion of the fabric in each side in the vicinity of the joining portion 50 of the main body part 10 is absorbed, and thus it is possible to suppress the occurrence of floating or wrinkles of the cloth in each side in the vicinity of the joining portion 50 of the main body part 10.
(89) Further, in the knee joint bandage 100 according to this embodiment, as shown in
(90) The first engaging part 30 according to this embodiment has a planar shape of a combination of, for example, a rectangle and an isosceles trapezoid, as shown in
(91) Similarly, the second engaging part 40 according to this embodiment has a planar shape of a combination of, for example, a rectangle and an isosceles trapezoid, as shown in
(92) In this manner, in the first engaging part 30 (the second engaging part 40), the isosceles trapezoid portion 32 (the isosceles trapezoid portion 42) protrudes from the other end 10b of the main body part 10 (the other end 20b of the first anchor part 20), thereby becoming thinner by an amount that does not overlap the main body part 10 (the first anchor part 20), whereby it is easy to grip the isosceles trapezoid portion (the isosceles trapezoid portion 42) with the fingers of a wearer, and thus it is possible to easily attach and detach the hook face 33 (the hook face 43) with respect to the loop face 21 of the first anchor part 20.
(93) Next, a method of wearing the knee joint bandage 100 shown in
(94) In addition, in the following description, a case of wearing the knee joint bandage 100 on the right knee of a wearer will be described. However, in a case of wearing the knee joint bandage 100 on the left knee of the wearer, wearing is performed with the right knee, the outer surface of the lower leg, and the inner surface of the lower leg respectively replaced by the left knee, the inner surface of the lower leg, and the outer surface of the lower leg.
(95) A wearer fastens the first anchor part 20 around the thigh by disposing the first anchor part 20 in an extended state at the thigh by winding the first anchor part 20 around the thigh with the right hand while pressing one end 20a of the first anchor part 20 with the left hand with the center mark 22 of the first anchor part 20 fitted to the center of the thigh in the vicinity of the kneecap, and making the hook face 43 of the second engaging part 40 which is located at the other end 20b of the first anchor part 20 be engaged with the loop face 21 of the first anchor part 20, as shown in
(96) Then, the wearer pulls the main body part 10 while gripping the main body part 10 with the right hand and disposes the main body part 10 (the first supporting part 12) in an extended state at the left side of a part corresponding to a patella 300 of the right knee.
(97) Next, the wearer makes the main body part 10 (the winding part 11) in an extended state circle around the lower leg by one round and a half in a direction from the outer surface of the lower leg to the inner surface of the lower leg through a part corresponding to the gastrocnemius by using both hands, as shown in
(98) Then, the wearer disposes the main body part 10 (the second supporting part 13) in an extended state at the right side of the part corresponding to the patella 300 of the right knee while gripping the other end 10h of the main body part 10 with the right hand.
(99) Finally, the wearer makes the hook face 33 of the first engaging part 30 which is located at the other end 10b of the main body part 10 be engaged with the loop face 21 of the first anchor part 20, as shown in
(100) In addition, in the wearing method of the knee joint bandage 100 described above, a case where in the start of winding of the main body part 10, the main body part 10 (the first supporting part 12) is disposed from the left side of the part corresponding to the patella 300 of the right knee has been described. However, the main body part 10 (the first supporting part 12) may be disposed from the right side of the part corresponding to the patella 300 of the right knee by using the knee joint bandage 100 shown in
(101) Further, the knee joint bandage 100 shown in
(102) Next, the optimal range of the maximum elongation in the warp direction in the main body part 10 of the knee joint bandage 100 according to this embodiment will be described based on the test results of a trial use test.
(103) In addition, in the trial use test, as shown in
(104) Further, knee joint bandages (hereinafter, respectively referred to as Comparative Example 1 and Comparative Example 2) were fabricated in the same manner as in the above examples by using the main body part 10 (length: 80 cm, width: 5 cm) having the maximum elongation of 35% or 90% and used in the trial use test.

(106) In the trial use test, the knee joint bandage was worn on the right knee of the wearer, as shown in
(107) Further, with respect to the evaluation item fixing force of
(108) Further, with respect to the evaluation item pain of
(109) Further, with respect to the evaluation item ease of peeling-off of touch fastener of
(110) Further, a touch fastener being not easily peeled off means that at the time of the wearer's movement, there is no case where the hook face of a touch fastener is separated from the loop face due to the movement of a joint or the expansion of a muscle in a site on which the bandage is worn, whereas the pile yarns are pulled out from the fabric having the loop face of a touch fastener due to a strong engaging force between the hook face and the loop face of a touch fastener, and thus, in a case where a touch fastener is peeled off, the pile yarns project from the fabric, thereby causing fluffing of the fabric.
(111) Further, with respect to the evaluation item close contact property of fabric of
(112) Further, with respect to the evaluation item ease of winding of
(113) Further, with respect to the evaluation item ease of adjustment of fixing force of
(114) Further, with respect to the evaluation item difficulty of fabric folding of
(115) In the evaluation items as described above, in Example 2, good evaluation results were obtained in almost all the evaluation items, as shown in
(116) Further, in Example 3, although the fixing force was weak, good evaluation results were obtained in other evaluation items.
(117) Further, in Example 1, although there was a pain and the close contact property of the fabric was poor, good evaluation results were obtained in other evaluation items. In contrast, in Comparative Example 1 and Comparative Example 2, poor evaluation results were obtained in most of the evaluation items.
(118) From the above, as the overall evaluation results, it is found that Example 1 (maximum elongation: 45%), Example 2 (maximum elongation: 60%), and Example 3 (maximum elongation: 75%), in which the average score is two or more points, are optimal as the main body part 10.
(119) That is, with respect to the maximum elongation in the warp direction in the main body part 10 of the knee joint bandage 100 according to this embodiment, a range of 40% to 80% is preferable, a range of 45% to 75% is more preferable, and the most preferred is 60%.
(120) Next, the first anchor part 20 of the knee joint bandage 100 according to this embodiment will be described based on the test results of a durability test (peeling strength) of a touch fastener.
(121) In addition, in the durability test (peeling strength) of a touch fastener of the first anchor part 20, an evaluation was performed by using the first anchor part 20 woven under the condition that the thickness of the elastic yarn 1c was changed from 840 deniers to 560 deniers and the number of times of picking (the number) of the weft 2 (the weft ground yarn 2a and the fusion yarn 2b) was in a range of 30.8 times (each 30.8 pieces) per 2.54 cm (1 inch) to 36.9 times (each 36.9 pieces) per 2.54 cm (1 inch), similar to the quality of the materials of the warp 1 and the weft 2 and the number of times of picking (the number) of the weft 2 of the main body part 10, so as to correspond to Example 2 (the main body part 10 in which the maximum elongation in the warp direction is 60%) in which the most favorable results were obtained from the evaluation results of the above-described sensory evaluation. Further, as comparative examples, commercially available stretchable fabrics (hereinafter, respectively referred to as Comparative Example 3, Comparative Example 4, and Comparative Example 5) made with the quality of the materials of the warp 1 and the weft 2 and the number of times of picking (the number) of the weft 2 shown in Table 2 below were used. In addition, Comparative Example 3 does not have a loop face as a touch fastener, and therefore, Comparative Example 3 is not provided with a pile yarn in a warp and a fusion yarn in a weft.
(122) TABLE-US-00002 TABLE 2 Number of times of Quality of material picking Warp Weft (Number) Warp Weft of weft Maximum ground Pile Elastic ground Fusion [times/ Thickness elongation yarn yarn yarn yarn yarn inch] [mm] Hardness [%] Example 2 WN100/2 210D-10F 560D EW150D Elder 36.9 2.1 Slightly 60 100D soft Comparative WN100/2 1120D Nylon 37.0 1.7 Soft 130 Example 3 mono- filament No. 1 Comparative WN100/2 210D-7F 1120D EW300D Elder 43.6 2.2 Normal 90 Example 4 100D Comparative WN100/2 210D-15F 1120D EW300D Elder 25.8 3.3 Hard 100 Example 5 100D
(123) Further, the major difference between Example 2 and Comparative Examples 3 to 5 is a difference in the filament count of the pile yarn, in which Example 2 has 10 pieces of filaments, whereas Comparative Example 4 has 7 pieces of filaments, Comparative Example 5 has 15 pieces of filaments, and Comparative Example 3 does not use a pile yarn (does not have a loop face of a touch fastener).
(124) The durability test (peeling strength) of a touch fastener is based on Japanese Industrial Standards JIS L3416, touch fastener, 7.4.2 peeling strength, and the experimental results obtained by carrying out a repeat of adhesion and peeling 1000 times are shown in Table 3 below.
(125) TABLE-US-00003 TABLE 3 Retention rate [%] Effective (peeling strength Change in width of after durability appearance fastener Peeling strength test/initial peeling after [cm] [N/cm] strength 100) durability test Example 2 4.7 Initial 0.358 181 Loop elongation After 0.649 which is less durability (than test Comparative Example 5) is recognized. Comparative 4.8 Initial 0.996 83 Violent Example 3 After 0.825 fluffing is durability recognized. test Comparative 4.7 Initial 0.281 90 Noticeable Example 4 After 0.254 change is not durability recognized. test Comparative 2.8 Initial 0.326 165 Slight loop Example 5 After 0.537 elongation is durability recognized. test
(126) In Example 2, as shown in Table 3, the retention rate (the percentage of peeling strength after durability test with respect to initial peeling strength) is the highest, compared to Comparative Examples 3 to 5, and thus it is found that Example 2 is optimal as the first anchor part 20 which is used in the knee joint bandage 100 which is wound around the knee and then engaged by the hooks of a touch fastener.
(127) In particular, in Example 2, the peeling strength after durability test becomes larger with respect to the initial peeling strength (the retention rate exceeds 100%), and therefore, Example 2 is advantageous in terms of a long-term continuing use as the knee joint bandage 100.
(128) Further, the filament count of the pile yarn being high means that the hooks of a touch fastener are easily engaged with the loops and the retention rate is increased, while the maximum elongation is lowered.
(129) In Comparative Example 5, the filament count of the pile yarn is higher than the filament count of the pile yarn of Example 2. However, resin processing is applied in order to prevent fluffing of external appearance, and therefore, it becomes difficult for the hooks of a touch fastener to be engaged with the loops, and the initial peeling strength and the retention rate become lower than the initial peeling strength and the retention rate of Example 2.
(130) As described above, in the knee joint bandage 100, the main body part 10 (the first supporting part 12 and the second supporting part 13) supports the patella of a wearer toward the thigh side from the lower leg side and supports the medial collateral ligament, whereby it is possible to facilitate the movement of the quadriceps muscle and suppress the deflection to right and left of the knee. That is, the main body part 10 (the first supporting part 12 and the second supporting part 13) supports the patella of a wearer from the lower leg side in an approximately X-shape crossing below the knee of the wearer, thereby being integrated with the movement of the quadriceps muscle, and thus it is possible to play a role like a splint suppressing the deflection to right and left of the knee.
(131) Further, in the knee joint bandage 100, the main body part 10 (the first supporting part 12 and the second supporting part 13) applies a strong pressing force toward the outer surface from the inner surface with respect to the knee of a wearer who wears the knee joint bandage 100, whereby in a case where the knee receives an external force from the outer surface side of the knee joint bandage 100, it is possible to generate a repulsive force toward the outer surface from the inner surface, which alleviates the external force, and thus the knee does not enter the inside due to the external force and it is possible to prevent damage to the medial collateral ligament.
(132) Further, in the knee joint bandage 100, the main body part 10 (the first supporting part 12 and the second supporting part 13) supports the outer surfaces of the thigh and the knee of a wearer who wears the knee joint bandage 100, thereby providing a balance with the pressing force which is applied to the inner surface by the main body part 10 (the first supporting part 12 and the second supporting part 13), and thus it is possible to maintain a stable standing state of the wearer.
(133) Further, the mounting of a knee supporter provided with band-shaped supporting parts equivalent to the first supporting part 12 and the second supporting part 13 of the knee joint bandage 100 is effective as a method for supporting the knee joint of a wearer. That is, due to mounting the knee supporter (for example, the knee joint bandage 100) so as to raise the patella of a wearer from the lower side to the upper side by disposing the band-shaped supporting parts (the first supporting part 12 and the second supporting part 13) on both right and left sides from the lower side of the part corresponding to the patella of the wearer, the band-shaped supporting parts support the patella of the wearer so as to raise it from the lower side to the upper side while gripping the patella of the wearer from the right and left, and therefore, it is possible to exhibit the operation and effects of reducing a burden on the knee region of the wearer by smoothly assisting in the movement of the quadriceps muscle.
(134) Further, the mounting of a knee supporter in which a band-shaped anchor part having a loop face, which is equivalent to the first anchor part 20 of the knee joint bandage 100, is provided at the knee supporter provided with the band-shaped supporting parts is more effective as a method for supporting the knee joint of a wearer. That is, due to mounting the knee supporter so as to raise the patella from the lower side to the upper side by making one end of the band-shaped supporting part (for example, the second supporting part 13) be engaged with the loop face of the band-shaped anchor part (for example, the first anchor part 20) fixed to the thigh of a wearer, the knee supporter is reliably fixed to the position of the knee joint of the wearer, and therefore, it is possible to more effectively exhibit the operation and effects of the band-shaped supporting part.
(135) Further, in the knee joint bandage 100 shown in
(136) Further, in the knee joint bandage 100, there is no limitation to these colors, and for example, it is conceivable that a yarn having any one color of seven colors (red, orange, yellow, green, blue, indigo, and violet) which are the rainbow colors is used for the pile yarn 1b of the warp 1 of the main body part 10 and the front ground face except for the pattern 14 of the main body part 10 is made to have any one color of the rainbow colors. In this way, the knee joint bandages 100 can encourage a consumer's willingness to buy with product groups with color variation of seven colors.
(137) Further, in the knee joint bandage 100, for example, the front ground face except for the pattern 14 of the main body part 10 is made to have a fluorescent color by using a fluorescent colored yarn for the pile yarn 1b of the warp 1 of the main body part 10, whereby a consumer's willingness to buy is encouraged, and the knee joint bandage 100 is worn during going out at night, whereby it is visible by being illuminated by the headlights of an automobile or the like, and thus it can be expected to contribute to the safety and disaster prevention as well.
Second Embodiment of the Present Invention
(138)
(139) The first anchor part 20 is provided with a slit 24 extending in the longitudinal direction L (the warp direction) of the main body part 10, at least between an upper side 20d of the first anchor part 20 and one end 10a of the main body part 10 in a state where the first anchor part 20 has been fastened around the thigh of a wearer (refer to
(140) In addition, in the following description, as necessary, the slit 24 which exists between the upper side 20d of the first anchor part 20 and one end 10a of the main body part 10 in a state where the first anchor part 20 has been fastened around the thigh of a wearer is referred to as a one end-side slit 24a, and the slit 24 which exists between the upper side 20d of the first anchor part 20 and the other end 10b of the main body part 10 in a state where the first engaging part 30 has been engaged with the first anchor part 20 is referred to as the other end-side slit 24b.
(141) Further, the slit 24 according to this embodiment has a length in a range of 5 cm to 9 cm, the distance from the lower side 20c of the first anchor part 20 to the slit 24 is in a range of 3 cm to 5 cm, and the distance from the upper side 20d of the first anchor part 20 to the slit 24 is in a range of 2 cm to 4 cm. However, if the slit 24 is longer than the length of one end 10a (the other end 10b) of the main body part 10 and the first anchor part 20 functions as an anchor of the main body part 10, there is no limitation to the position, the size (the length or the width), and the number of the slit 24 shown in
(142) In the main body part 10, as shown in
(143) The first engaging part 30 has a planar shape which is a parallelogram and is sewn to the back ground face of the main body part 10 without protruding from the other end 10b of the main body part 10, as shown in
(144) For this reason, as shown in
(145) Further, the second embodiment is different from the first embodiment only in that the slit 24 is newly provided in the first anchor part 20 of the knee joint bandage 100 and the shapes of the other end 10b of the main body part 10 and the first engaging part 30 are changed, and exhibits the operation and effects which are the same as those of the first embodiment except for the operation and effects by the slit 24, which will be described later.
(146) In the knee joint bandage 100 according to this embodiment, the first anchor part 20 is provided with the slit 24, whereby with respect to the tensile stress from the main body part 10, a force is dispersed in the fabric on the lower side 20c side of the first anchor part 20 with the slit 24 as a boundary and the influence on the fabric on the upper side 20d side of the first anchor part 20 is suppressed, and thus it is possible to maintain an anchor function by the fabric on the upper side 20d side of the first anchor part 20.
(147) Further, in the knee joint bandage 100 according to this embodiment, the first anchor part 20 is provided with the slit 24, whereby with respect to the flexion of the knee joint of a wearer, the fabric on the lower side 20c side of the first anchor part 20 moves down to follow the flexion while supporting is performed by the fabric on the upper side 20d side of the first anchor part 20, and with respect to the extension of the knee joint of a wearer, the fabric on the lower side 20c side of the first anchor part 20 moves up with a restoring force, and thus the operation and effects in which the first anchor part 20 can flexibly respond to the movement of the knee joint of a wearer are exhibited.
(148) Further, the knee joint bandage 100 according to this embodiment is provided with either of the one end-side slit 24a or the other end-side slit 24b, whereby the operation and effects described above are newly exhibited with respect to the knee joint bandage 100 according to the first embodiment which is not provided with the slit 24.
(149) However, in a case where the slit 24 is provided on only one side, sliding-down of the first anchor part 20 on the fabric side where the slit 24 is provided, due to the tensile stress from the main body part 10, is suppressed, whereas sliding-down of the first anchor part 20 on the fabric side where the slit 24 is not provided occurs, whereby a balance of the crossing portion by the first supporting part 12 and the second supporting part 13 below the knee is not maintained and the operation and effects by the slit 24 are halved. For this reason, in the knee joint bandage 100 according to this embodiment, it is preferable that two slits 24; the one end-side slit 24a and the other end-side slit 24b, are provided.
Third Embodiment of the Present Invention
(150)
(151) A knee joint supporter 200 according to the present invention comprises: the first anchor part 20 which is woven in a fabric having the loop face 21 of a touch fastener and is fastened around the thigh of a wearer; the main body part 10 which is a band-shaped fabric and is composed of a second anchor part 211 which is disposed at least below the popliteal region of the wearer, the first supporting part 12 which is disposed in a taut state on one side from below a part corresponding to the patella 300 of the wearer, and the second supporting part 13 which is disposed in a taut state on the other side of the part corresponding to the patella 300 of the wearer to cross the first supporting part 12 below the part corresponding to the patella 300 of the wearer; and connection parts 70 which are joined to the first anchor part 20 and the second anchor part 211, thereby integrating the first anchor part 20 and the main body part 10, as shown in
(152) In addition, the second anchor part 211 according to this embodiment corresponds to the winding part 11 according to the first embodiment and the second embodiment, and also in this embodiment, the second anchor part 211 is provided between the first supporting part 12 and the second supporting part 13, thereby configuring the main body part 10, and the first supporting part 12, the second anchor part 211, and the second supporting part 13 have straight line shapes having the same width.
(153) Further, the connection parts 70 according to this embodiment are a pair of left and right bag-shaped parts 71 each containing a support 72 and are disposed in a taut state on both sides of the part corresponding to the patella of a wearer.
(154) In addition, in the following description, in order to distinguish the left and right bag-shaped parts 71 (supports 72), in

(182) Further, with respect to the weft ground yarn 2a of the main body part 10 according to this embodiment, it is preferable to use a single piece of polyester woolly yarn (EW) having a thickness of 150 deniers.
(183) Further, the main body part 10 according to this embodiment does not have a loop face of a touch fastener, and therefore, the weft 2 of the main body part 10 is not provided with the fusion yarn 2b holding loops by the pile yarn 1b. However, the main body part 10 according to this embodiment may have the fusion yarn 2b in the weft 2 of the main body part 10 and have a loop face of a touch fastener, similar to the main body part 10 according to the first embodiment.
(184) Further, in the main body part 10 according to this embodiment, a single piece of weft ground yarn 2a is picked as the weft 2 by a power loom, and the number of times of picking (the number) of the weft 2 (the weft ground yarn 2a) is 33.6 times (33.6 pieces) per 2.54 cm (1 inch).
(185) Further, with respect to the weft ground yarn 2a of the first anchor part 20 according to this embodiment, it is preferable to use a single piece of polyester woolly (EW) single yarn having a thickness of 150 deniers.
(186) Further, with respect to the fusion yarn 2b of the first anchor part 20 according to this embodiment, it is preferable to use a single piece of nylon thermal fusion yarn (for example, Elder (registered trademark) manufactured by Toray Industries, Inc.) having a thickness of 100 deniers.

(188) In this manner, in the main body part 10 according to this embodiment, due to the quality of the materials of the warp 1 and the weft 2 (in particular, the thicknesses of the elastic yarn 1c and the weft ground yarn 2a) described above and the number of times of picking (the number) of the weft 2 described above, it is possible to set the maximum elongation in the warp direction (the longitudinal direction L) to be 60%. Further, the main body part 10 according to this embodiment has a mixing ratio of nylon: 47%, polyester: 44%, and polyurethane: 9%. However, there is no limitation to this mixing ratio.
(189) Further, in the first anchor part 20 according to this embodiment, due to the quality of the materials of the warp 1 and the weft 2 (in particular, the thicknesses of the elastic yarn 1c and the weft ground yarn 2a) described above and the number of times of picking (the number) of the weft 2 described above, it is possible to set the maximum elongation in the warp direction (the longitudinal direction L) to be 95%.
(190) Further, the first anchor part 20 according to this embodiment has a mixing ratio of nylon: 66%, polyester: 24%, and polyurethane: 10%. However, there is no limitation to this mixing ratio.
(191) Further, in the main body part 10, in order to configure a crossing portion below the knee and a lower anchor, the lengths of portions (the first supporting part 12 and the second supporting part 13) which cross each other below the knee of a wearer, and the length of a portion (the second anchor part 211) which circles at least half around the lower leg of the wearer below the popliteal region of the wearer are required, and although there is an individual difference in the circumference of the knee or the thickness of the lower leg according to gender, age, or the like, it is conceivable that the length of the main body part 10 is set to in, for example, a range of 44 cm to 52 cm (for example, S-size: 44 cm, M-size: 48 cm, L-size: 52 cm).
(192) Further, in the first anchor part 20 according to this embodiment, in order to circle around the thigh of a wearer, for example, it is preferable to set the length of the band-shaped body to be in a range of 29 cm to 37 cm (for example, S-size: 29 cm, M-size: 33 cm, L-size: 37 cm).
(193) Further, with respect to the bag-shaped part 71 of the connection part 70 according to this embodiment, a 100% polyester double Russell fabric (for example, part number 7200SK of Inoue Knit Co., Ltd.) is used, and the double Russell fabric having a rectangular shape (for example, longitudinal size: 17.5 cm, transverse size: 6 cm) is folded in half with the support 72 sandwiched therebetween and is sewn at a peripheral edge portion excluding the folded portion, whereby a structure containing the support 72 is made.
(194) Further, as long as it is a fabric having shock-absorbing properties, the bag-shaped part 71 is not limited to the double Russell fabric, and for example, a fabric obtained by bonding other fabrics to both sides of neoprene, a fabric obtained by bonding other fabrics to both sides of urethane foam, or the like is also acceptable.
(195) Further, the left bag-shaped part 71a (the right bag-shaped part 71b) according to this embodiment is joined (for example, sewn) from the back fabric side with an upper side of the left bag-shaped part 71a (the right bag-shaped part 71b) aligned with the upper side 20d of the first anchor part 20, at a position where the distance from one end 20a (the other end 20b) of the first anchor part 20 to the center line of the left bag-shaped part 71a (the right bag-shaped part 71b) is about 6 cm, and is joined (for example, sewn) from the back fabric side with a lower side of the left bag-shaped part 71a (the right bag-shaped part 71b) aligned with a lower side of the main body part 10, at a position where the distance from one end 10a (the other end 10b) of the main body part 10 to the center line of the left bag-shaped part 71a (the right bag-shaped part 71b) is about 14.5 cm. However, it is preferable that the joining position of the bag-shaped part 71 (the left bag-shaped part 71a and the right bag-shaped part 71b) is appropriately set in consideration of the maximum elongation in the warp direction (the longitudinal direction L) of each of the main body part 10 and the first anchor part 20.
(196) That is, the distance between an upper end of the left bag-shaped part 71a (the left support 72a) and an upper end of the right bag-shaped part 71b (the right support 72b) and the distance between a lower end of the left bag-shaped part 71a (the left support 72a) and a lower end of the right bag-shaped part 71b (the right support 72b) are not limited to being the same as each other and may have different (wider or narrower) configurations, and it is preferable that the distances are appropriately set in consideration of the maximum elongation in the warp direction (the longitudinal direction L) of each of the main body part 10 and the first anchor part 20.
(197) Further, with respect to the support 72 which is contained in the bag-shaped part 71 according to this embodiment, a PP plate containing 100% polypropylene (PP) and having a thickness in a range of 1.2 mm to 4.0 mm is used. However, there is no limitation to the PP plate having the plate thickness and the quality of material, and for example, polyethylene foam (for example, Sunpelca (registered trademark) or Belporen (foamed polyethylene)), a hard vinyl chloride plate, a hard gum (rubber) plate, a polycarbonate plate, or the like is also acceptable. Further, the support 72 according to this embodiment is not limited to a plate-shaped body and may be, for example, a columnar body such as a circular column or a rectangular column, a columnar body having a hollow or a groove extending in a longitudinal direction, a columnar body with a separate member fitted into a hollow or a groove extending in a longitudinal direction, or the like.
(198) In particular, the support 72 contained in the bag-shaped part 71 is a plate-shaped body having flexibility which is bent in a direction perpendicular to a principal surface (is not easily bent in a direction horizontal to a principal surface), and in this way, in a case where a wearer has flexed the knee joint, due to the restoring force of the support 72 bent in a direction perpendicular to the principal surface, a force trying to return the knee joint of the wearer to a normal position acts.
(199) Further, the bag-shaped part 71 (the left bag-shaped part 71a and the right bag-shaped part 71b) is joined at the back fabric sides of the main body part 10 and the first anchor part 20, whereby the connection part 70 (the support 72) is provided on the inside (the wearer side) with respect to the main body part 10 and the first anchor part 20 in a state where the knee joint supporter 200 has been worn.
(200) For this reason, it is possible to press an upper end and a lower end of the connection part 70 (the bag-shaped part 71 and the support 72) with the main body part 10 and the first anchor part 20, and thus it is possible to prevent the protrusion of the upper end and the lower end of the connection part 70 (the bag-shaped part 71 and the support 72).
(201) In particular, the upper end of the connection part 70 (the bag-shaped part 71) and the first anchor part 20 are joined to each other with the upper side 20d of the first anchor part 20 folded from the upper side 20d side of the first anchor part 20 to the back fabric side and the upper end of the connection part 70 (the bag-shaped part 71) gripped by the folded portion of the first anchor part 20, whereby the upper end of the bag-shaped part 71 is reinforced, and thus it is possible to prevent damage to the upper end of the bag-shaped part 71 by the support 72.
(202) Next, a method of wearing the knee joint supporter 200 shown in
(203) In addition, in the following description, a case of wearing the knee joint supporter 200 on the right knee of a wearer will be described. However, in a case of wearing the knee joint supporter 200 on the left knee of the wearer, wearing is performed with the right knee, the outer surface of the lower leg, and the inner surface of the lower leg respectively replaced by the left knee, the inner surface of the lower leg, and the outer surface of the lower leg.
(204) A wearer fastens the first anchor part 20 around the thigh by disposing the first anchor part 20 in an extended state at the thigh by winding the first anchor part 20 around the thigh with the right hand while pressing one end 20a of the first anchor part 20 with the left hand with one end 20a of the first anchor part 20 fitted to the center of the thigh in the vicinity of the kneecap, and making the hook face 43 of the second engaging part 40 which is located at the other end 20b of the first anchor part 20 be engaged with the loop face 21 of the first anchor part 20, as shown in
(205) In this case, the left connection part 70 (the left bag-shaped part 71a and the left support 72a) is disposed between the patella 300 and the sartorius muscle of the wearer, and the right connection part 70 (the right bag-shaped part 71b and the right support 72b) is disposed between the patella 300 and the iliotibial band of the wearer.
(206) Then, the wearer pulls the first supporting part 12 of the main body part 10 while gripping one end 10a of the main body part 10 (the first supporting part 12) with the right hand and disposes the first supporting part 12 of the main body part 10 in an extended state from below the part corresponding to the patella 300 of the right knee to the right side.
(207) Then, the wearer makes the hook face 63 of the third engaging part 60 which is located at one end 10a of the main body part 10 be engaged with the loop face 21 of the first anchor part 20, as shown in
(208) Then, the wearer grips the other end 10b of the main body part 10 (the second supporting part 13) with the left hand and disposes the second supporting part 13 of the main body part 10 in an extended state on the left side while crossing the first supporting part 12 below the part corresponding to the patella 300 of the right knee.
(209) Finally, the wearer makes the hook face 33 of the first engaging part 30 which is located at the other end 10b of the main body part 10 be engaged with the loop face 21 of the first anchor part 20, as shown in
(210) In addition, in the wearing method of the knee joint supporter 200 described above, a case where after the first supporting part 12 of the main body part 10 is disposed from the right side of the part corresponding to the patella 300 of the right knee, the second supporting part 13 of the main body part 10 is disposed from the left side of the part corresponding to the patella 300 of the right knee has been described. However, the first supporting part 12 of the main body part 10 may be disposed from the right side of the part corresponding to the patella 300 of the right knee after the second supporting part 13 of the main body part 10 is disposed from the left side of the part corresponding to the patella 300 of the right knee.
(211) As described above, in the knee joint supporter 200, the main body part 10 (the first supporting part 12 and the second supporting part 13) fixes the patella 300 (the knee joint) of a wearer so as to wrap the patella 300 (the knee joint) while raising the patella 300 (the knee joint) from below toward the thigh side from the lower leg side and supports the medial collateral ligament and the medial collateral ligament of the wearer, whereby it is possible to smoothly assist in the movement of the quadriceps muscle, and it is possible to reduce a burden on the knee by suppressing the deflection to right and left of the knee.
(212) Further, in the knee joint supporter 200, the main body part 10 (the first supporting part 12 and the second supporting part 13) grips and presses the knee joint of a wearer from the right and left and limits extra extension of the knee ligament (the medial collateral ligament and the medial collateral ligament) of the wearer, whereby it is possible to suppress the abrasion of the cartilage or the inflammation of the ligament of the knee joint and prevent damage to the knee joint.
(213) In particular, the knee joint supporter 200 according to this embodiment is provided with the connection parts 70, whereby even in a state where the second anchor part 211 is pulled by the first supporting part 12 and the second supporting part 13, the distance between the first anchor part 20 and the second anchor part 211 is maintained, and the crossing portion of the first supporting part 12 and the second supporting part 13 moves upward based on the extension of the first supporting part 12 and the second supporting part 13 while preventing sliding-up of the second anchor part 211, and thus it is possible to sufficiently fulfill a function of pushing up the patella 300 by the crossing portion.
(214) Further, the mounting of a knee supporter provided with two band-shaped supporting parts equivalent to the first supporting part 12 and the second supporting part 13 of the knee joint supporter 200 is effective as a method for supporting the knee joint of a wearer. That is, due to mounting the knee supporter (for example, the knee joint supporter 200) so as to raise the patella of a wearer from the lower side to the upper side by disposing the two band-shaped supporting parts (for example, the first supporting part 12 and the second supporting part 13) on both right and left sides after crossing at the lower side of the part corresponding to the patella of the wearer, the two band-shaped supporting parts support the patella of the wearer so as to raise the patella from the lower side to the upper side with the crossing portion of the two band-shaped supporting parts as a point of action on the patella of the wearer while the two band-shaped supporting parts grip the patella of the wearer from the right and left, and therefore, it is possible to exhibit the operation and effects of reducing a burden on the knee region of the wearer by smoothly assisting in the movement of the quadriceps muscle.
(215) Further, the mounting of a knee supporter in which a band-shaped anchor part having a loop face, which is equivalent to the first anchor part 20 of the knee joint supporter 200, is provided at the knee supporter provided with the two band-shaped supporting parts is more effective as a method for supporting the knee joint of a wearer. That is, due to mounting the knee supporter so as to raise the patella from the lower side to the upper side by making one end of each of the two band-shaped supporting parts (for example, the first supporting part 12 and the second supporting part 13) be engaged with the loop face of the band-shaped anchor part (for example, the first anchor part 20) fixed to the thigh of a wearer, the knee supporter is reliably fixed to the position of the knee joint of the wearer, and therefore, it is possible to more effectively exhibit the operation and effects of the two band-shaped supporting parts.
(216) In addition, the knee joint supporter 200 according to this embodiment has been described using the main body part 10 in which the second anchor part 211, the first supporting part 12, and the second supporting part 13 are integrally woven to be continuous. However, as shown in
(217) In this case, the second anchor part 211 is woven in a fabric having a loop face 211e of a touch fastener, and a fourth engaging part 80 having a hook face of a touch fastener, which is detachably stuck to the loop face 211e of the second anchor part 211, is provided on the back ground face side of one end 211a or the other end 211b (in
(218) In the case of this form, as shown in
(219) Further, in the knee joint supporter 200 according to this embodiment, as shown in
(220) In this case, in the mounting of the first anchor part 20 in the wearing method of the knee joint supporter 200, as shown in
(221) Then, the wearer fastens the first anchor part 20 around the thigh by pulling the other end 20b (the second engaging part 40) and one end 20a (the grip 25) in the opposite directions in a state of gripping the other end 20b (the second engaging part 40) of the first anchor part 20 with the left hand and gripping one end 20a (the grip 25) of the first anchor part 20 with the right hand, and then making the hook face 43 of the second engaging part 40 be engaged with the loop face 21 of the first anchor part 20.
(222) In this manner, in a case of pulling one end 20a of the first anchor part 20, which is not easily gripped due to the second engaging part 40 not being present therein, with the right hand, the grip 25 is easily hooked to and gripped with the finger of a wearer, and thus it is possible to assist in the pulling by a wearer such as a powerless woman or aged person.
(223) Further, in the knee joint supporter 200 according to this embodiment, a case where the pattern 14 described in the first embodiment is not formed in the main body part 10 has been described. However, as necessary, the pattern 14 may be formed in the main body part 10 by using a jacquard needle loom.

(227) Further, with respect to the covering part 73 according to this embodiment, a cloth which is a cotton-blended power net (for example, part number CI1543 (mixing ratio: nylon 60%, (yarn count: 56 decitexes), cotton 23%, (yarn count: 40 single yarn), and polyurethane 17% (thread count: 310 decitexes) of Inoue knit Co., Ltd.) is used.
(228) However, as long as it is a fabric having stretchability, the covering part 73 is not limited to the cotton-blended power net and may be, for example, a cloth such as: a two-way tricot raised fabric (for example, part number NS4426K (mixing ratio: polyester 85% and polyurethane 15%, warp knitting machine gauge number: 28 gauges, weight per unit area: 250 g/m.sup.2, thread for weaving: polyester yarn obtained by twisting 36 pieces of filaments together and having a thickness of 56 decitexes, and polyurethane yarn having a thickness of 44 decitexes) of Inoue knit Co., Ltd.) which is a warp knitting fabric or a weft knitting fabric, has raising on the back ground face, and extends in a longitudinal direction and a transverse direction; a warp knitting two-way tricot fabric (as a thread for weaving, for example, part number 3100 (mixing ratio: polyester 83% and polyurethane 17%) of Inoue knit Co., Ltd., or part number 5100 (mixing ratio: nylon 85% and polyurethane 15%) of Inoue knit Co., Ltd.); a 100% polyester double Russell fabric (for example, part number 7200SK of Inoue Knit Co., Ltd.); or a circular knitting bare plain fabric (as a thread for weaving, for example, part number YG103 (mixing ratio: cotton 95% and polyurethane 5%) of Inoue knit Co., Ltd.).
(229) Further, the fourth embodiment is different from the third embodiment only in that the fourth embodiment is provided with the covering part 73, and exhibits the operation and effects which are the same as those in the third embodiment except for the operation and effects by the covering part 73, which will be described later.
(230) In the knee joint supporter 200 according to this embodiment, the covering part 73 is provided on the inside (the wearer side) with respect to the first anchor part 20, the second anchor part 211, and the bag-shaped parts 71 (the supports 72), whereby in a case where a wearer has flexed the knee joint, the covering part 73 serves as a shock-absorbing material, and thus it is possible to alleviate a feeling of discomfort due to the skin of the popliteal region being sandwiched between the first anchor part 20 and the second anchor part 211 which approach each other.
(231) Further, in the covering part 73 according to this embodiment, in the area overlapping the first anchor part 20, the covering part 73 is sewn at the upper side 20d of the first anchor part 20 and both sides and is not sewn at the lower side 20c of the first anchor part 20, and in the area overlapping the second anchor part 211, the covering part 73 is sewn at a lower side 211c of the second anchor part 211 and some of the lower sides of both sides and is not sewn at the upper side 211d of the second anchor part 211.
(232) Due to these sewing positions, the covering part 73 in which the maximum elongations of the first anchor part 20 and the second anchor part 211 are different from each other is prevented from following the extension movements of the first anchor part 20 and the second anchor part 211 as much as possible, and thus it is possible to suppress the occurrence of wrinkles of the covering part 73.
(233) In particular, in the knee joint supporter 200 according to this embodiment, as shown in
(234) Further, in the knee joint supporter 200 according to this embodiment, the upper side 20d of the first anchor part 20 is folded from the upper side 20d side of the first anchor part 20 to the back fabric side, and the upper ends of the covering part 73 and the connection parts 70 (the bag-shaped parts 71) are joined to be gripped with the folded portion of the first anchor part 20, whereby the upper ends of the bag-shaped parts 71 are reinforced, and thus it is possible to prevent damage to the upper ends of the bag-shaped parts 71 by the supports 72.
(235) Further, in the knee joint supporter 200 according to this embodiment, the connection part 70 composed of the bag-shaped part 71 containing the support 72, and the covering part 73 has been described. However, if it is a configuration in which the first anchor part 20 and the main body part 10 (the second anchor part 211) are integrated, the connection part 70 composed of the covering part 73 is also acceptable.
(236) Further, a case where each of the knee supporters (the knee joint bandages 100 and the knee joint supporters 200) according to the first embodiment to the fourth embodiment is directly wound around the bare skin has been described. However, with respect to the knee joint on which, for example, a knee joint supporter disclosed in Pamphlet of International Publication No. WO/2011/090194 or an innerwear (spats, stockings, or tights and panty-stockings) having a knee part is worn, the knee supporter (the knee joint bandage 100 or the knee joint supporter 200) is wound on the knee joint supporter or the innerwear, thereby eliminating the slip of the knee supporter (the knee joint bandage 100 or the knee joint supporter 200) with respect to the bare skin, whereby it is possible to improve the operation and effects of the knee supporter (the knee joint bandage 100 or the knee joint supporter 200).
(237) Further, in a case where each of the knee joint bandages 100 according to the first embodiment and the second embodiment is wound on the innerwear, it is also possible to provide the knee joint bandage 100 and the innerwear as a set.
(238) Further, in a case where each of the knee joint bandages 100 according to the first embodiment and the second embodiment is wound on the innerwear (an innerwear in which the maximum elongation is low is preferable), as an aspect of the knee joint bandage 100, the first anchor part 20 of the knee joint bandage 100 is removed from the main body part 10 and one end 10a of the main body part 10 is sewn to the outer surface or the inner surface above the knee part of the innerwear, whereby it is possible to make the thigh part circumference of the innerwear function as the first anchor part 20.
