DESCRIPTION OF EMBODIMENTS

[0027] The following describes an embodiment for carrying out the present disclosure with reference to the drawings. As illustrated in FIG. 1 and FIG. 2 for example, a waist belt 1 of the present disclosure can be formed substantially in a diamond outer shape viewed from the front side, in which: the neighborhood of the center of the back side thereof to be worn on a waist portion 81 of a user 8 is the widest; and a left main belt 2 and a right main belt 3 extending leftward and rightward narrow toward a left end 21 and a right end 32, respectively. It is thought possible that the left main belt 2 and the right main belt 3 may be formed to have the same widths from the back side to the front side. However, because the user 8 is compressed by immobilization of an abdominal portion thereof, the waist belt 1 preferably has the outer shape of this example that is relatively narrower in the front side when being worn (refer to FIG. 6 and FIG. 7 to be explained later).

[0028] The waist belt 1 of this example includes: a left main belt 2, a right main belt 3, a left inner tightening belt 43, a left outer tightening belt 44, a right inner tightening belt 53, and a right outer tightening belt 54 that are nonstretchable; and a left subsidiary tightening belt 6 and a right subsidiary tightening belt 7 that are stretchable. The left main belt 2, the right main belt 3, the left inner tightening belt 43, the left outer tightening belt 44, the right inner tightening belt 53, and the right outer tightening belt 54 are preferably formed of nonstretchable cloth, which does not stretch upward, downward, rightward, or leftward. The left main belt 2 and the right main belt 3 may be entirely flexible so as to fit tightly on the waist portion 81 of the user 8, or may be stretchable upward and downward. Directions in which the left subsidiary tightening belt 6 and the right subsidiary tightening belt 7 stretch are preferably limited to directions of their extension so as to be effectively stretchable in the directions of their extension.

[0029] The left main belt 2 and the right main belt 3 have bilaterally symmetric structures. Therefore, descriptions of the right main belt 3 are added in parentheses to those of the left main belt 2, and differences therebetween are described separately. The left main belt 2 (right main belt 3) has, in a development view (FIG. 1) from the back side, a structure such that: at the right end 22 (left end 31) of a belt main body 24 (belt main body 34) made of mesh cloth that tapers from the right end 22 (left end 31) toward the left end 21 (right end 32), an antislip folded-binding part 244 (antislip folded-binding part 344) is provided; an elastic reinforcement resin core is inserted into the antislip folded-binding part 244 (antislip folded-binding part 344); on the outer surface of the left-half area of the belt main body 24 (belt main body 34) from the left end 21 (right end 32), a male surface 242 of a hook-and-loop fastener (male surface 342 of the hook-and-loop fastener) are attached; and binding 243 (binding 343) is provided on the outer rim of the belt main body 24 (belt main body 34) excluding the reinforcement part 244 (reinforcement part 344).

[0030] The belt main body 24 (belt main body 34) made of mesh cloth functions not only to allow secure ventilation so as to prevent stuffiness due to the waist belt 1 covering the waist portion 81 of the user 8 but also to reduce the weight of the waist belt 1 to no small extent. The antislip folded-binding part 244 (antislip folded-binding part 344) has an antislip device provided on the front side thereof that makes surface contact with the waist portion 81 of the user 8 and causes the right end 22 (left end 31) of the belt main body 24 (belt main body 34) to follow the waist portion 81 of the user 8 with elastic deformation of the reinforcement resin core inserted therethrough. At the same time, by the action of the reinforcement resin core, the antislip folded-binding part 244 (antislip folded-binding part 344) suppresses or prevents twisting and deformation of the right end 22 (left end 31) due to tensile force generated when being pulled by the left inner tightening belt 43 (right inner tightening belt 53) and the left subsidiary tightening belt 6 (right subsidiary tightening belt 7) that are attached to the right end 22 (left end 31).

[0031] In the left main belt 2 (right main belt 3), sewing attachment of the antislip folded-binding part 244 (antislip folded-binding part 344) is utilized to have the right end 432 (left end 531) of the left inner tightening belt 43 (right inner tightening belt 53) connected to the belt main body 24 (belt main body 34) in a lower stage (an upper stage) of the lower half of the right end 22 (left end 31). Therein, the right end 442 (left end 541) of the left outer tightening belt 44 (right outer tightening belt 54) is slipped under a female surface 242 of the hook-and-loop fastener (female surface 342 of the hook-and-loop fastener), thereby being connected to the belt main body 24 (belt main body 34). Furthermore, in the left main belt 2 (right main belt 3), sewing attachment of the antislip folded-binding part 244 (antislip folded-binding part 344) is utilized to have a right folding-back ring 23 (left folding-back ring 33), through which the right inner tightening belt 53 (left inner tightening belt 43) is passed, provided to an upper stage (a lower stage) of the lower half of the right end 22 (left end 31) via an attachment flap attached to the right inner tightening belt 53 (left inner tightening belt 43). The right folding-back ring 23 (left folding-back ring 33) is preferably made of resin.

[0032] The right main belt 3 of this example, the male surface 341 of the hook-and-loop fastener is provided on the inner side of the right end 32, as illustrated in FIG. 2. This structure enables the waist belt 1 of this example to be worn in the following manner. With the right end 22 and the left end 31 of the left main belt 2 and the right main belt 3 placed on the waist portion 81 of the user 8 while being opposed to each other, the right main belt 3 wound around from the right side in the same manner as the left main belt 2 is overlaid on the left main belt 2 wound around from the left side and brought into surface contact with an abdominal portion of the user 8, and the male surface 341 of the hook-and-loop fastener provided on the inner surface of the right end 32 of the right main belt 3 is engaged with the female surface 242 of the hook-and-loop fastener provided on the outer surface of the left main belt 2 (refer to FIG. 6 and FIG. 7 to be explained later).

[0033] The left inner tightening belt 43 (right inner tightening belt 53) is extended rightward (leftward) from the right end 22 (left end 31), of the left main belt 2 (right main belt 3), to which the right end 432 (left end 531) thereof is connected and passed through the left folding-back ring 33 (right folding-back ring 23) to be folded back leftward (rightward), and has a left linking ring 433 (right linking ring 533) provided at the left end 431 (right end 532). The left inner tightening belt 43 (right inner tightening belt 53) is made of the same nonstretchable belt material as a conventional waist belt or the like of the same kind is made of. The left linking ring 433 (right linking ring 533) is preferably made of resin.

[0034] The left outer tightening belt 44 (right outer tightening belt 54) is extended rightward (leftward) from an end edge of the female surface 242 of the hook-and-loop fastener (the female surface 342 of the hook-and-loop fastener) to which the right end 442 (the left end 541) is connected, is passed through the left linking ring 433 (right linking ring 533) and folded back leftward (rightward), is passed further through the left fixation ring 45 (right fixation ring 55) and folded back rightward (leftward), and has the left end 441 (right bed 542) connected to the left end 61 (right end 72) of the left subsidiary tightening belt 6 (right subsidiary belt 7). The left fixation ring 45 (right fixation ring 55) is preferably made of resin. A left tab 451 (right tab 551) provided with a male surface of the hook-and-loop fastener is attached to the left fixation ring 45 (right fixation ring 55). The left outer tightening belt 44 (right outer tightening belt 54) and the left tab 451 (right tab 551) are made of the same belt material as the left inner tightening belt 43 (right inner tightening belt 53).

[0035] The left subsidiary tightening belt 6 of this example is a rubber belt stretchable in the direction of extension thereof, has the right end 62 thereof connected to the upper half of the right belt main body 34 by utilizing the sewing attachment of the antislip folded-binding part 344, is connected to an insertion ring 63 at one point, has a part thereof that continues from this point extended leftward from the insertion ring 63, and has the left end 61 thereof connected to the left end 441 of the left outer tightening belt 44. The insertion ring 63 serves as an undeformable through-hole formed in the middle of the left subsidiary tightening belt 6. The right subsidiary tightening belt 7 of this example is a rubber belt stretchable in the direction of extension thereof likewise, has the left end 71 thereof connected to the upper half of the left belt main body 24 by utilizing the sewing attachment of the antislip folded-binding part 244, is passed through the insertion ring 63 and extended rightward, and has the right end 72 thereof connected to the right end 542 of the right outer tightening belt 54.

[0036] The waist belt 1 of this example (refer to FIG. 1 and FIG. 2) has, between the right end 22 of the left main belt 2 and the left end 31 of the right main belt 3, the left inner tightening belt 43, the right inner tightening belt 53, the left subsidiary tightening belt 6, and the right subsidiary tightening belt 7 arranged next to each other in this order from the lower side to the upper side, so that the width of the waist belt 1 has a wide width (length in the upward/downward direction) obtained by adding the widths of these belts. Here, if it is desired that a width of a surface making contact with the waist portion 81 of the user 8 be somewhat narrower, the width of the waist belt 1 can be reduced, for example, in the following manner as in the case of a modification example 1 illustrated in FIG. 3. The right inner tightening belt 53 passed through the right folding-back ring 23 and folded back is extended rightward after being inserted through the left folding-back ring 33 through which the left inner tightening belt 43 is passed to be folded back, so that the levels of the right folding-back ring 23 and the left folding-back ring 33 are uniformed.

[0037] The waist belt 1 of this example is configured to have the left main belt 2 and the right main belt 3 strongly tightened through folding back in two stages, which is achieved on one hand by the left inner tightening belt 43 and left outer tightening belt 44 that are nonstretchable being folded back, and on the other hand by the right inner tightening belt 53 and the right outer tightening belt 54 being tightened likewise. If such strong tightening is not needed, a left tightening belt 4 and a right tightening belt 5 that are nonstretchable can be used while being folded back in one stage, for example, in a manner as in the case of a modification example 2 illustrated in FIG. 4 or a modification example 3 illustrated in FIG. 5. The waist belt 1 of the modification example 2 corresponds to the example (refer to FIG. 1 and FIG. 2) by including the left tightening belt 4 and the right tightening belt 3 are suspended through the left folding-back ring 33 and the right folding-back ring 23, respectively, that are located at upper and lower neighboring positions. The waist belt 1 of the modification example 3 corresponds to the modification example 1 (refer to FIG. 3) with the left folding-back ring 33 and the right folding-back ring 23 the levels of which are uniformed, and with the right tightening belt 3 passed through the left folding-back ring.

[0038] In the waist belt 1 of each of the modification example 2 and the modification example 3, the left tightening belt 4 (right tightening belt 5) has the right end 42 (left end 51) thereof connected to the right end 22 (left end 31) of the left main belt 2 (right main belt 3) by utilization of the sewing attachment of the antislip folded-binding part 244 (antislip folded-binding part 344), is passed through the left folding-back ring 33 (right folding-back ring 23) connected to the left end 31 (right end 22) of the right main belt 3 (left main belt 2) and folded back leftward (rightward), and is passed further through the left fixation ring 45 (right fixation ring 55) and folded back rightward (leftward), and has the left end 41 (right end 52) thereof connected to the left end 61 (right end 72) of the left subsidiary tightening belt 6 (right subsidiary tightening belt 7). The left tightening belt 4 (right tightening belt 5) is made of the same nonstretchable belt material as a conventional waist belt or the like of the same kind is made of.

[0039] The waist belt 1 of the example is worn on the waist portion 81 of the user 8, for example, in the following manner (while it is obvious that the user 8 is free to follow any manner in which to wear it). In the waist belt 1, the following is performed in advance. The left tab 451 of the left fixation ring 45 and the right tab 551 of the right fixation ring 55 are detached from the female surfaces 242 and 342 of the hook-and-loop fastener that are provided on the outer surface the left main belt 2, so that the right main belt 3, and the left inner tightening belt 43, the left outer tightening belt 44, the right inner tightening belt 53, and the right outer tightening belt 54 are loosened. The user 8 places the thus loosened waist belt 1 on the waist portion 81 of the user 8 in a manner such that the left and right antislip folded-binding parts 244 and 344 can be bilaterally symmetric across the backbone; then winds around the left main belt 2 from the left side to the front side first; then winds around the right main belt 3 from the right side to the front side; and engages the male surface 341 of the hook-and-loop fastener on the left main belt 2 with the female surface 242 of the hook-and-loop fastener. In this manner, the waist belt 1 is wound around the waist portion 81 of the user 8 to the extent that it is kept from falling off.

[0040] Starting from this state, the following is performed, so that wearing the waist belt 1 is completed as illustrated in FIG. 6 and FIG. 7. The left tab 451 is pulled from the left side toward the front side; and, at the point where the left inner tightening belt 43, the left outer tightening belt 44, and the left subsidiary tightening belt 6 are adequately tightened, the male surface of the hook-and-loop fastener provided on the left tab 451 is engaged with the female surface 242 provide on the outer surface of the left main belt 2, so that the left fixation ring 45 is fixed. Likewise, the right tab 551 is pulled from the right side toward the front side; and, at the point where the right inner tightening belt 53, the right outer tightening belt 54, and the right subsidiary tightening belt 7 are adequately tightened, the male surface of the hook-and-loop fastener provided on the right tab 551 is engaged with the female surface 342 provide on the outer surface of the right main belt 3, so that the right fixation ring 63 is fixed.

[0041] In the waist belt 1 of the example, while the waist belt 1 is worn on the waist portion 81 of the user 8, a set of the left inner tightening belt 43 and the left outer tightening belt 44 and a set of the right inner tightening belt 53 and the right outer tightening belt 54 squeeze tight around the lower half of the waist portion 81, and the left subsidiary tightening belt 6 and the right subsidiary tightening belt 7 squeeze tight around an upper part of the constricted waist portion 81 at the same time, so that the left main belt 2 and the right main belt 3 are brought into wide surface contact with the waist portion 81 (refer to FIG. 7). Here, how much the left inner tightening belt 43, the left outer tightening belt 44, and the left subsidiary tightening belt 6 squeeze and how much the right inner tightening belt 53, the right outer tightening belt 54, and the right subsidiary tightening belt 7 squeeze are made different by how the left tab 451 and the right tab 551 are pulled. Therefore, levels of squeezing in the left and the right sides can be made different while the left main belt 2 and the right main belt 3 are kept making wide surface contact with the waist portion 81.

[0042] When the user 8 moves while wearing the waist belt 1, the left subsidiary tightening belt 6 and the right subsidiary tightening belt 7 individually elongate and contract, and the left main belt 2 and the right main belt 3 are kept in tight contact with the upper half of the constricted waist portion 81. At the same time, the elongation and contraction of the left subsidiary tightening belt 6 and the right subsidiary tightening belt 7 absorb the move of the user 8, so that the left outer tightening belt 44 and the right outer tightening belt 54, and, via the left outer tightening belt 44 and the right outer tightening belt 54, the left inner tightening belt 43 and the right inner tightening belt 53 are allowed to follow the move of the user 8 while being pulled and kept tense. Consequently, the left main belt 2 and the right main belt 3 can be kept making wide surface contact with the waist portion 81.
