DETAILED DESCRIPTION OF THE INVENTION

[0055] In describing the present invention, certain known functions that are relevant to the invention but are apparent to a person skilled in the art will not be described in great detail, if it is deemed that this may unnecessarily obscure the essence of the present invention.

[0056] The functional mat 1 for assisting deep sleep for an infant based on an embodiment of the present invention may include a mat body 10, a side supporter 30, and a pressure supporter 50. FIG. 1 conceptually illustrates the functions of the mat body 10 and the side supporter 30. In particular, various forms of the side supporter 30 are illustrated. Although the drawing does not show variations of the mat body 10, the physical dimensions of the mat body 10 can also be modified. In implementing the spirit of the present invention, the sizes and forms of the mat body 10, side supporter 30, and pressure supporter 50 do not limit the scope of the present invention.

[0057] The mat body 10 may serve as a mat of a cushioned material on which an infant's body 100 (hereinafter referred to as ‘object’) may be laid. Therefore, the mat body 10 may support the object 100 in an upward direction.

[0058] Since the mat body 10 supports the infant's body, it may be made of a cushion material. Various types of cushion material can be used. The cushion material can be selected to include one or more of latex, memory foam, polyurethane, air cushion, cotton filler, and substitutes thereof. Also, the mat body 10 may be composed with such a cushion material as an inner lining and natural cotton as an outer lining that receives the cushion material. The outer lining may desirably be composed such that its surface allows sufficient air permeability. This can improve the feel on the skin and allow convenient washing. Such properties of the cushion material can also apply to the side supporter 30 described below. Of course, the pressure supporter can also be partially or entirely made of a cushion material as above.

[0059] When sleeping, people usually lie facing sideways. This is also true for infants. The side supporter 30 may support the object 100 in a sideward direction of the object 100. The sideward direction′ may be understood more in regard to the side of the object 100, rather than the side of the mat body 10. To support the object 100 in a sideward direction, the side supporter 30 may form a sidewall with respect to the surface of the mat body 10. That is, the side supporter 30 may be characterized as a structure that protrudes in a perpendicular direction from the surface of the mat body 10 in a generally gently sloping hill-like shape.

[0060] FIG. 1(a) shows an example in which the side supporter 30 is installed at one side with respect to a lengthwise direction of the mat body 10. With the embodiment of FIG. 1(a), a plan view (looking at the drawing from the front) shows a structure in which a center portion of the side supporter 30 protrudes towards the middle of the mat body 10 on which the object 100 is laid. Because of this structure, the side supporter 30 is given a convex portion and concave portions. The concave portions provide room for accommodating movement by the body parts of the object 100. The convex portion may press the object 100 on the chest from the side, to provide ‘comfortable pressure’ as sought by the present invention.

[0061] FIG. 1(b) shows an example in which the side supporter 30 is structured to curve in an arc-like shape towards the object 100 in a plan view. By thus restricting movement by the body parts of the object 100, an environment similar to that attained when a parent holds a sleeping child can be provided. Of course, in this case also, the gently curved shape can protrude the furthest at the portion corresponding to the chest area, so as to provide ‘comfortable pressure’.

[0062] FIG. 1(c) shows a variation that combines the advantages of the structure shown in FIG. 1(a) and the structure shown in FIG. 1(b). The movement by the face and legs of the object 100 is more restricted, but the pressure on the chest area of the object 100 is similarly more emphasized.

[0063] The edge 19 at the end of the mat body opposite the position of such side supporter 30 can be made to be higher than the surface of the center portion of the mat body. This is to restrict the object 100 from rolling in the opposite direction.

[0064] From FIG. 1, it can be seen that the side supporter 30 protruding above the surface of the mat body 10 in a hill-like shape can be implemented in a variety of forms. However, the installation position of the side supporter 30 need not be limited to one side of the mat body 10 as illustrated in FIG. 1. This is clearly illustrated in FIG. 2.

[0065] FIG. 2(a) can be regarded as an example corresponding to FIG. 1. The side supporter 30 is installed at a side of the mat body 10. While just one may be installed as illustrated in the drawing, it is also possible to install a multiple number of side supporters 30.

[0066] In FIG. 2(b), there are side supporters 30 installed on the upper, lower, left, and right sides of the mat body 10. This may restrict the object lying on the mat body 10 from moving upwards or downwards. While this can provide the advantage of ensured stability, the area of the mat can be decreased as a result. Of course, this would not be a problem if the dimensions of the mat itself are increased. Sufficient large dimensions for the mat can also provide the advantage of accommodating two or more objects.

[0067] FIG. 2(c) illustrates a composition in which the side supporters 30 are installed on both sides of the mat body 10. FIG. 2(d) illustrates a composition in which the side supporter 30 is installed near the center of the mat body 10. Thus, due to the presence of the side supporter 30, a functional mat based on an embodiment of the present invention may include, not a flat composition like a bed, but a hill region gently protruding towards an upper space with respect to the surface, with this hill region restricting sideways movement of the object 100. The reason for restricting the sideways movement is to structurally ensure that comfortable pressure is provided in relation with the pressure supporter described below.

[0068] A description is now provided on the various positions and forms in which the side supporter 30 may be installed. For sure, the side supporter 30 may be installed on the mat body 10, but in a certain embodiment can also be installed in an integrated form. As first embodiment of an integrated installation can involve the mat body 10 and the side supporter 30 manufactured in an integrated form (for example, molded and cast as an integrated body and covered with an outer lining). A second embodiment of an integrated installation can involve manufacturing the mat body 10 and the side supporter 30 separately but provided to the consumer after the side supporter 30 is attached to the mat body 10. For example, the side supporter 30 can be secured onto a surface of the mat body 10 with a fastening means such as velcro, etc., after which the two can be processed simultaneously with an outer lining to complete the mat according to an embodiment of the present invention.

[0069] In another embodiment of the present invention, the side supporter 30 can be detachably coupled. In other words, the user can connect or disengage the side supporter 30 to or from the mat body 10 as necessary.

[0070] The details of the detachable coupling can be devised in various ways. One embodiment is illustrated in FIG. 3. A fastening hole 35 can be provided which penetrates through a mat edge side and a lower surface of the side supporter 30, and a fastener 11a that is installed on the mat body 10 can be inserted through this fastening hole 35, whereby the side supporter 30 can be fastened to the mat body 10. The fastener 11a can include a pair of rings and a string attached to each ring, as in the illustration. As will be described again later on, the fastening hole 35 and fastener 11a can also be used to fasten the pressure supporter as well.

[0071] Although it is not shown in the drawings, the detachable coupling of the side supporter 30 and the mat body 10 can employ various means, such as velcro fasteners, male and female buttons, zippers, strings, etc. Structurally, the fastening hole 35 can be used in conjunction with fastening means such as the velcro, zipper, string, button, buckle, etc., for connecting the side supporter 30 with the mat body 10. The spirit and scope of the present invention are not limited by variations of the detachable coupling

[0072] FIG. 4 illustrates the basic composition of a mat 1 according to a certain embodiment of the present invention. The manner in which the mat body 10, side supporter 30, and pressure supporter 50 are coupled is illustrated. When the side supporter 30 is installed onto the mat body 10 as illustrated in the drawing, a side wall may be formed with respect to the hilled summit portion 31 of the side supporter 30. Then, by installing the pressure supporter 50, an environment for providing comfortable pressure to the object (not shown) may be achieved.

[0073] As illustrated in FIG. 4(a), the side supporter 30 may be positioned at a side surface of the mat body 10. The fastening hole 35 of the side supporter 30 described with reference to FIG. 3 can be formed as a hole that penetrates through a position corresponding to the edge of the mat body, a position on the opposite side, and a position on the lower surface. As illustrated in FIG. 4(b), a connector piece 51 on one end of the pressure supporter 50 may be inserted into this fastening hole 35. Also, as shown in FIG. 4(c), the fastener 11a of the mat body 10 may also be inserted into the fastening hole 35.

[0074] Next, by connecting the fastener 11a of the mat body 10 with the connector piece 51 of the pressure supporter 50, the main components of the present invention can be coupled together. Preferably, a velcro fastener can be installed on one side of the connector piece 51, in which case the connector piece 51 can be inserted through a ring of the fastener 11a, and the connector piece 51 can be formed into a loop for fastening. It would also be possible to have the connector piece 51 inserted through the ring of the fastener 11a and formed into a knot.

[0075] FIG. 4 shows an example of how the pressure supporter 50 may be implemented. In the arrangement shown in FIG. 4(c), when the object is laid down, the opposite end of the pressure supporter 50 may be moved in the direction of the side supporter 30. Afterwards, the connector piece 52 on the opposite side may be connected with the ring of the fastener 11a on the mat body 10. Then, the object laid on the mat body 10 may naturally turn towards the side supporter 30, resulting in a posture shown in FIG. 1. When the connector piece 52 of the pressure supporter 50 is pulled adequately, the side supporter 30 can provide comfortable pressure from the object's side (chest area), while the pressure supporter 50 can provide comfortable pressure towards the object from the top. Also, the side supporter 30 and the pressure supporter 50 structurally prevent the infant from flipping over during sleep. Therefore, use of the present invention may prevent occurrences in which an infant suffers asphyxiation during slumber.

[0076] Preferably, a cushion filling part 55 may be installed on the pressure supporter 50. The cushion filling part 55 may desirably be installed at a position facing the object; more preferably, the cushion filler may desirably be positioned inside the outer lining of the pressure supporter 50 in such a way that its position can be adjusted. That is, a holding space may additionally be installed that is longer than the cushion filler along the lengthwise direction of the pressure supporter 50.

[0077] The pressure supporter 50 installed to be detachably coupled with the mat 1 may have one side positioned below the object and the other side positioned over the object, as shown in the embodiment of FIG. 4. This is also true for the embodiment shown in FIG. 5. However, the embodiment of FIG. 5 proposes a variation on the method of fastening the pressure supporter 50 onto the mat 1.

[0078] The embodiment shown in FIG. 5 differs from the embodiment of FIG. 4 in that the functional mat has the mat body 10 and the side supporter 30 implemented as an integrated body. In this case also, a fastener 11b may be installed at an edge portion of the side supporter 30, and a connector piece 51 on one side of the pressure supporter 50 may be secured to this fastener 11b. Then, the connector piece 52 on the other side of the pressure supporter 50 may be moved in the direction of the arrow to be connected and secured to the fastener 11b. The method of connecting the pressure supporter 50 to the mat 1 for securing may be the same as that described for FIG. 4. Also, there can be numerous variations. The mechanism for providing the object with comfortable pressure may also be no different.

[0079] FIG. 6 proposes another embodiment having the pressure supporter 50 connected to the mat 1.

[0080] As with the embodiment of FIG. 5, the mat body 10 and the side supporter 30 can be secured as an integrated body. Of course, it would also be possible to achieve the securing with a zipper running along the edge of the mat body 10. In any case, one side of the pressure supporter 50 may be secured through a lower surface of the side supporter 30, with its end portion formed as a buckle 54 that is exposed outside roughly near a center portion of the side supporter 30. After one end of the pressure supporter 50 is secured by way of the above composition, the object may be positioned over the pressure supporter 50, and the other side may be moved towards the side fabric 50 and fastened using the buckle 54. Here, the object may be placed in close contact with the side supporter 30. Also, the cushion filling part 55 may contact the object.

[0081] FIG. 7 proposes another embodiment having the pressure supporter 50 installed on the mat 1. This embodiment emphasizes an alternative method of securing the one end of the pressure supporter 50. As illustrated in FIG. 7, a securing ring 56 may be installed at one end of the pressure supporter 50, and a fitter element 60 having elasticity may be fitted into this securing ring 56. As the connection between the securing ring 56 and the fitter element 60 occurs at the lower surface of the side supporter 30, it may not be exposed to the exterior. The opposite side of the fitter element 60 may be inserted through and connected to a securing ring 33 installed at a lower surface of the side supporter 30. With this composition implemented, the side supporter 30 can be installed on the mat body 10 using the method described above or a variation thereof to complete the functional mat based on an embodiment of the present invention. Similarly, the filler for the cushion filling part 55 can be implemented such that its position is adjustable within the outer lining of the pressure supporter 50.

[0082] The embodiments above show that each of the various types of pressure supporters 50, when used for the object, has a portion that is positioned crossing over the surface of the mat body 10 along a widthwise direction of the mat body 10. That is, at least one element of the pressure supporter 50 is positioned crossing along the widthwise direction of the mat body 10 over the object, in close contact with the object.

[0083] FIG. 8 schematically illustrates the front structure of a functional mat 1 for assisting deep sleep for an infant in another embodiment of the present invention. The functional mat 1 for assisting deep sleep for an infant may include a mat body 10 and a pair of wings 20a, 20b. In this embodiment, this pair of wings 20a, 20b may serve as a pressure supporter. In particular, this embodiment provides an example of the pressure supporter intersecting in a widthwise direction of the mat body 10 to be positioned over the surface of the mat body 10.

[0084] A child may lie over the surface of the mat body 10. Since the mat body 10 supports the infant's body, it may be made of a cushion material. This is no different from the embodiment of FIG. 1.

[0085] The infant's head may be positioned at the upper side of the mat body 10, while the legs may be positioned at the lower side. Curves may desirably be formed at the head region portion 11 of the mat body 10. Also, the thickness of the head region portion 11 may desirably be greater than the thickness of the leg region portion. This will be described again later on.

[0086] The pair of wings 20a, 20b may be connected to both sides of the mat body 10, respectively. As in the illustration, the wings 20a, 20b may desirably be implemented such that the width at the root of a wing is greater than the width at the sleeve of the wing. Such an arrangement prevents the infant from feeling constricted when the wings 20a, 20b are folded, and at the same time, continues to provide comfort even if a restless infant's body moves beyond the mat body 10.

[0087] The pair of wings 20a, 20b may also be desirably made of a cushioned material. In a certain embodiment of the present invention, the cushion material of the wings 20a, 20b can be of the same type as the cushion material of the mat body 10. In another embodiment of the present invention, the cushion material of the wings 20a, 20b can be of a different type from the cushion material of the mat body 10. In particular, one or more of latex, memory foam, polyurethane, cotton filler, and substitutes thereof can desirably be selected. Also, such a cushion material may be used as an inner lining, with natural cotton as an outer lining that receives the cushion material. This can improve the feel on the skin and allow convenient washing.

[0088] In an embodiment of the present invention, a pair of wings 20a, 20b may be folded in directions facing each other to be folded over the mat body 10, and in order that this operating mechanism may be performed more naturally, folding lines 25a, 25b can also be formed in the wings 20a, 20b, as in the illustration.

[0089] A fastening means 21, 22 can be installed left and right on the sleeve portion of each wing 20a, 20b. In the illustration, a fastening piece 21 is installed on one wing 20b, while a fastening part 22 that uses velcro coupling with the fastening piece 21 is installed on the other wing 20a, as an example of a fastening means. However, it is obvious that numerous variations are possible. For instance, the fastening means may include a knot or a button. By folding and securing a pair of wing parts in this manner, it is possible to provide comfortable pressure to the object.

[0090] FIG. 9 shows an example of the rear composition of a functional mat 1 based on an embodiment of the present invention. In an embodiment of the present invention, a functional mat 1 is proposed in which the mat body and the pair of wings are separable, rather than being coupled as an integrated body. From FIG. 9, it can be seen not only that the pair of wings 20a, 20b can be detachably coupled with the mat body but also that the coupling position can be varied.

[0091] As shown in FIG. 9, on the rear surface 10b of the mat body, multiple numbers of wing coupler parts 17, 18 can be installed on the left and right sides along the lengthwise direction of the mat body. After selecting the wing coupler parts 17, 18, the coupler pieces 27, 28 installed at the root positions of the wings 20a, 20b can be coupled to or separated from the coupler parts 17, 18.

[0092] Since the positions for coupling the pair of wings 20a, 20b to the mat body 10 can be selected along the left and right lines as in the illustration, the positions of the wings 20a, 20b can be varied according to the infant's body.

[0093] Also, the method of coupling the wing coupler parts 17, 18 and the coupler pieces 27, 28 can be devised in various ways. Preferably, a velcro coupling can be used. For instance, the wing coupler parts 17, 18 installed along the left and right lines on the rear surface 10b of the mat body can have female velcro parts, while the coupler pieces 27, 28 installed on the root positions of the wings 20a, 20b can have male velcro parts. This arrangement would allow velcro coupling. Also, the wing coupler parts 17, 18 and the coupler pieces 27, 28 can be formed as male and female buttons to allow button-based detachable coupling. In another example, the wing coupler parts can be formed as rings, and the coupler pieces 27, 28 of the wings 20a, 20b can be placed into the rings and tied in knots.

[0094] FIG. 10 shows examples of cross sections for each component of the functional mat 1 in the embodiment illustrated in FIG. 8.

[0095] FIG. 10(a) shows the cross section of the mat body 10 along the lengthwise direction. As illustrated in this drawing, the thickness of the mat body 10 can be made different overall. As described earlier, by having the head region portion 11 of the mat body 10 thicker than the leg region portion, it is possible to let the child feel more comfortable. With this arrangement, the head region portion 11 may serve as a headrest.

[0096] FIG. 10(b) shows a cross section across an upper portion, i.e. the head region portion 11, after rotating the mat body 10 of FIG. 10(a) by 90 degrees, in a certain embodiment of the present invention. As can be seen from the embodiment of FIG. 10(b), curves can be formed in the head region portion 11 in an embodiment of the present invention, where the curves may be formed with the thickness of the inner portion smaller than the thickness of the two end portions, thus forming a recess, so that the infant's head can be positioned ergonomically in the recess. Next, as the pair of wings 20a, 20b are connected facing each other, the wings 20a, 20b may enwrap the child's body and apply a particular amount of pressure. In this manner, an infant's back sensor problem could be considerably improved. This was analyzed to be because the resulting effect is similar to that of a parent laying down a child that has begun to fall asleep and gently pressing the child's chest with both hands.

[0097] FIG. 10(c) illustrates another embodiment of the present invention. Shown is a cross section across an upper portion, i.e. the head region portion 11, after rotating the mat body 10 of FIG. 10(a) by 90 degrees. Unlike FIG. 10(b), the curved portion in FIG. 10(c) does not have a convex portion instead of a recess formed in the middle. This arrangement can optimally respond to a child's habit of sleeping on his/her side. Also, while the child is lying on his/her side, the wings 20a, 20b may be connected facing each other, so that the wings 20a, 20b may enwrap the child's body and apply a particular amount of pressure. In this manner, the infant's so-called back sensor problem could be resolved most effectively.

[0098] FIG. 10(d) shows an example of the cross section of a pair of wings 20a, 20b based on an embodiment of the present invention. As shown in FIG. 10(d), the pair of wings 20a, 20b can be made of a cushion material, and can include folding lines 25a, 25b.

[0099] FIG. 11 illustrates an example of how a functional mat 1 based on an embodiment of the present invention may be used. While the child 100 is laid down, the pair of wings 20a, 20b can be folded, and the pair of wings 20a, 20b can be overlapped and fastened together using the fastening means 21 on each wing 20a, 20b, at a position above the mat body 10. Fastening the pair of wings in this manner can protect the child's body, and at the same time, the pair of wings 20a, 20b can be positioned at the child's chest area, so that the weight of the wings and the pressure created by the fastening may apply comfortable pressure on the child's chest.

[0100] This fastening mechanism of the pair of wings 20a, 20b may implement a function analogous to a parent gently pressing a laid child's chest with a hand to allow the child to sleep more soundly. An infant sleeping on a mat can experience a sensation similar to a parent pressing his/her chest and can thus sleep more comfortably. From tests performed after fabricating a model of a functional mat based on an embodiment of the present invention, the inventor of the present invention has found that the pair of wings coupled together facing each other provide pressure on a child's chest, and as a result, the child's habit of waking and crying when laid down was almost eliminated. On a function mat 1 based on an embodiment of the present invention, the child was able to sleep comfortably and safely. This would provide the added effect of enabling the parent to perform other tasks with an easy mind.

[0101] FIG. 12 shows another possible application of an embodiment of the present invention. On one side of the surface of a mat body 10 based on an embodiment of the present invention, a height measurement marking part 40 can be installed along a lengthwise direction of the mat body 10. The height measurement marking part 40 can have calibrated lines like those on a ruler. With a height measurement marking part installed as an integrated body on a surface of the mat body 10, it is possible to measure the height of a child after laying the child down on the mat body 10. Babies and infants grow at a fast pace, and information regarding a child's height may serve as a very important measure of health. As such, parents inevitably have great interest in their children's height information. An advantageous effect obtained is that, whenever a child is laid down and put to sleep on an arrangement such as the embodiment of the present invention shown in FIG. 5, the parents can intuitively see the child's growth information. In situations where the child is awake, the child's body can be straightened out for accurate measurement of height.

[0102] The height measurement marking part 40 can be installed by sewing an element having calibrated lines onto the surface of the mat body 10. Here, it would be preferable to use the same material as that of the outer lining of the mat body 10 so as not to degrade the child's tactile feel. Also, in another embodiment, the calibrated lines can be printed onto the outer lining of the mat body 10, so that the height measurement marking part 40 may be formed as an integrated body on the surface of the mat body 10.
