(Embodiment)
As shown in FIG. 1, the leg pillow 1 includes a leg covering portion 10 having a strip shape that can be wound around the lower leg 100 (see FIG. 5), and a leg covering so that the leg covering portion 10 fits the lower leg 100. A first adjusting unit 20 and a second adjusting unit 30 (see FIG. 3) capable of adjusting a tightening force that is a strength for tightening the unit 10 are provided.

  The leg covering portion 10 includes a substantially circular support portion 11 that is a cushion that supports the calf and a pair of belt-like winding portions 12 that extend in a point-symmetric manner from the side portion of the support portion 11. The leg covering portion 10 is configured by sewing a plurality of fabrics together. An example of the dough is a charcoal sheet formed from Bincho charcoal. The inner surface 1A of the leg pillow 1 shown in FIG. 1 and the outer surface 1B of the leg pillow 1 shown in FIG. 3 are formed of charcoal sheets. The seam 13 shown in FIG. 3 is a charcoal sheet seam, and is formed at the center of the leg covering portion 10 in the longitudinal direction.

  The support part 11 is formed by a central support part 11A constituting the central part thereof, and an outer peripheral support part 11B surrounding the periphery of the central support part 11A. The charcoal sheet that forms the inner surface 1A and the charcoal sheet that forms the outer surface 1B are stitched together to form the central support portion 11A and the outer peripheral support portion 11B in the support portion 11 that is a cushion.

  As shown in FIG. 2, beads 14 made of expanded polystyrene are spread inside the support portion 11. For this reason, when the leg covering portion 10 is wound around the lower leg 100 (see FIG. 5), the lower leg 100 is given a soft touch. The outer surface 1B of the central support portion 11A swells more than the inner surface 1A of the central support portion 11A.

  As shown in FIG. 1, the leg pillow 1 includes two sets of first adjustment units 20. An example of the first adjustment unit 20 is a hook-and-loop fastener. The hook-and-loop fastener includes a hook 21 (see FIG. 3) attached to the outer surface 1B (see FIG. 3) of the support portion 11 and a loop 22 attached to the inner surface 1A of the winding portion 12. A set of hooks 21 and loops 22 that are symmetrical to each other in the longitudinal direction of the leg covering portion 10 with respect to the seam 13 (see FIG. 3) constitutes one hook-and-loop fastener. The hook 21 is disposed across the outer surface 1B of the center support portion 11A and the outer surface 1B of the outer periphery support portion 11B. The loop 22 is disposed in a wide range of the winding part 12. An example of the material of the loop 22 is a nonwoven fabric that can provide a soft touch to the user.

  By hooking the hook 21 and the loop 22 together, the state in which the leg covering portion 10 is wound around the lower leg 100 (see FIG. 5) is maintained. By adjusting the position where the loop 22 is attached to the hook 21 in the longitudinal direction of the hook 21, the contact length of the leg covering portion 10 wound around the lower leg 100 is adjusted. The tightening force becomes stronger as the contact length of the leg covering portion 10 becomes shorter.

  As shown in FIG. 3, the leg pillow 1 includes two sets of second adjustment units 30. The second adjustment unit 30 includes a tightening piece 31 formed of an elastic material, and an elastic adjustment unit 32 that adjusts an elastic force that is a force generated by the tightening piece 31. The fastening pieces 31 are two rubbers bundled as shown in FIG. 1, and are arranged across the support portion 11 and the winding portion 12.

  The winding part 12 includes a hole 12A through which the fastening piece 31 passes. By passing the fastening piece 31 through the hole 12A, as shown in FIG. 1, the first mounting portion 31A, which is one end portion of the fastening piece 31, is arranged on the inner surface 1A side of the support portion 11, and FIG. 3, the second attachment portion 31 </ b> B that is the other end of the fastening piece 31 is disposed on the outer surface 1 </ b> B side of the winding portion 12. The first attachment portion 31A is stitched to the inner surface 1A of the support portion 11. The second attachment portion 31 </ b> B is attached to the winding portion 12 by the elasticity adjusting portion 32.

  As shown in FIG. 4, the fastening piece 31 includes a fixing piece 31 </ b> C extending from the second attachment portion 31 </ b> B. The end of the fixing piece 31C is stitched to the outer surface 1B of the winding part 12. For this reason, the maximum range in which the portion of the fastening piece 31 arranged on the outer surface 1B side of the winding part 12 can be adjusted with respect to the winding part 12 is regulated by the fixing piece 31C. For this reason, the second attachment portion 31B of the fastening piece 31 is unlikely to move to the inner surface 1A (see FIG. 1) side of the winding portion 12 through the hole 12A of the winding portion 12.

  An example of the elasticity adjusting unit 32 is a hook-and-loop fastener. The surface fastener includes a hook 33 attached to the second attachment portion 31B of the fastening piece 31, and a loop 34 attached to the outer surface 1B of the winding portion 12 and the fixed piece 31C. The loop 34 is arranged in the first loop 34A arranged along the longitudinal direction of the winding portion 12, the second loop 34B arranged around the first loop 34A, and the first loop arranged in the fixing piece 31C. 3 loops 34C. An example of the material of the second loop 34B is a nonwoven fabric that can provide a soft touch to the user. The coupling force between the first loop 34A and the hook 33 and the coupling force between the third loop 34C and the hook 33 are stronger than the coupling force between the second loop 34B and the hook 33.

  By hooking the hook 33 and the loop 34 together, the second attachment portion 31B of the fastening piece 31 is coupled to the outer surface 1B of the winding portion 12. The elasticity of the fastening piece 31 is adjusted by adjusting the position where the hook 33 is attached to the loop 34 in the longitudinal direction of the loop 34. The attaching position of the hook 33 with respect to the loop 34 includes a position where the fastening piece 31 does not substantially generate elasticity. This position is, for example, a position where the hook 33 is bonded to the third loop 34C, and is selected when it is not desired to increase the tightening force of the support portion 11 (see FIG. 3) by the tightening piece 31.

  When the hook 33 is bonded to the loop 34 so that the fastening piece 31 generates elasticity, the elasticity of the fastening piece 31 acts on the support portion 11 and the winding portion 12 by the elasticity of the fastening piece 31. For this reason, compared with the case where the elastic force of the fastening piece 31 is not acting, the fastening force of the support part 11 becomes large.

5 to 7 show an example of the usage state of the leg pillow 1.
The leg pillow 1 is typically attached to the lower leg 100 through the following procedure. In the first procedure, the leg pillow 1 is deployed as shown in FIG. In the second procedure, the leg covering portion 10 is wound around the lower leg 100 so that the inner surface 1A (see FIG. 1) of the deployed leg pillow 1 covers the circumference of the lower leg 100 in a state where the user stands or sits down. It is done. In the third procedure, the hook 21 (see FIG. 3) and the loop 22 (see FIG. 1) of one of the first adjusting sections 20 are bonded together. In the fourth procedure, the hook 21 and the loop 22 of the other first adjustment unit 20 are bonded together. According to the third procedure and the fourth procedure, the application position of the loop 22 with respect to the hook 21 is adjusted by the user so that an appropriate tightening force is applied to the lower leg 100. By completing the fourth procedure, the leg pillow 1 is wound around the lower leg 100 as shown in FIG.

  In the fifth procedure, the hook 33 and the loop 34 of one second adjustment unit 30 are bonded to each other. In the sixth procedure, the hook 33 and the loop 34 of the other second adjustment unit 30 are bonded to each other. According to the fifth procedure and the sixth procedure, an appropriate tightening force is applied to the lower leg 100, or the second adjuster 30 is not substantially tightened against the loop 34 so that the tightening force is not generated. The attaching position of the hook 33 is adjusted by the user. By completing the sixth procedure, the leg pillow 1 is attached to the lower leg 100.

  When an appropriate tightening force is applied to the lower leg 100 by the first adjustment unit 20 in the third procedure and the fourth procedure, the tightening force of the second adjustment unit 30 is not substantially generated. The hook 33 is attached to the loop 34 with the tightening piece 31 loosened. On the other hand, when the tightening force applied to the lower leg 100 by the first adjusting unit 20 is insufficient, the position where the hook 33 is applied to the loop 34 is adjusted so that the tightening force is increased. FIG. 6 shows a state in which the tightening force of the leg covering portion 10 is strengthened by the second adjusting portion 30.

  When the fastening piece 31 generates elasticity, the second attachment is performed by the inner surface 1A (see FIG. 1) of the support portion 11 coupled to the first attachment portion 31A (see FIG. 1), and the hook 33 and the loop 34. The elasticity acts on the outer surface 1B of the winding part 12 coupled to the part 31B. That is, the tightening force of the leg covering portion 10 increases. For this reason, even if the preferred fit between the leg pillow 1 and the lower leg 100 cannot be obtained only by adjusting the tightening force by the first adjusting unit 20, the second adjusting unit 30 solves the problem. Or the extent of the problem is reduced.

  As shown in FIG. 7, when the user goes to bed with the leg pillow 1 attached to the lower leg 100, the inner surface 1 </ b> A (see FIG. 1) of the support portion 11 contacts the calf and the outer surface 1 </ b> B of the support portion 11 is connected to the bedding 200. Contact. By supporting the lower leg 100 by the support portion 11, the state where the heel is lifted from the bedding 200 is maintained in a state where the calf is tightened by the leg pillow 1. For this reason, the muscle pumping action is improved and the bleeding of blood from the blood vessels is suppressed, so that the lower leg is hardly swollen at bedtime.

According to the leg pillow 1 of the above embodiment, the following effects are obtained.
(1) In the early stages of technical development, the structure of a leg pillow for improving the effect of suppressing swelling of the legs was examined. As a result, it was confirmed that the effect of suppressing the swelling of the legs could be enhanced if the leg pillows could be fitted tightly to the legs according to the shape of the legs that were different for each user. Based on the result of this examination, the leg pillow 1 is provided with a structure in which the tightening force can be adjusted by the first adjusting unit 20 in the above embodiment. Thereby, since the leg pillow 1 is attached to the leg and the tightening force is adjusted according to the shape of the leg, the leg pillow 1 fits more securely to the leg of the user than the conventional leg pillow. For this reason, the suppression effect of the swelling of a leg is further heightened.

  Further, when the user moves the leg pillow 1 attached to the lower leg 100, the leg pillow 1 is not easily displaced from the leg. For this reason, it is difficult to re-adjust the position of the leg pillow 1, and the convenience of the leg pillow 1 is enhanced.

  (2) In the case of the conventional technique in which the shape of the leg covering portion is formed in a cylindrical shape, that is, compared to the case where the leg covering portion cannot be developed in a belt shape, the leg pillow 1 of the above embodiment has a The attachment state of the leg covering portion 10 can be flexibly adjusted. For this reason, an appropriate tightening force is easily applied to the lower leg 100.

  (3) According to the leg pillow 1, the tightening force can be adjusted by the second adjusting unit 30 in addition to the first adjusting unit 20. For this reason, an appropriate tightening force can be easily applied to the leg according to various leg shapes, thereby further enhancing the leg swelling effect.

  (4) According to the leg pillow 1, the tension generated by the first attachment portion 31 </ b> A on the inner surface 1 </ b> A of the support portion 11 is adjusted by adjusting the position where the hook 33 is attached to the loop 34 in the longitudinal direction of the loop 34. Because of the change, the tightening force of the leg covering portion 10 is adjusted. Further, since the second attachment portion 31 </ b> B is attached to the outer surface 1 </ b> B of the winding portion 12, the user can easily adjust the tightening force by the second adjustment portion 30.

  (5) The fastening piece 31 includes a fixing piece 31C that is formed so as to extend from the second attachment portion 31B and is sewn to the outer surface 1B of the winding portion 12. For this reason, the second attachment portion 31B of the fastening piece 31 is unlikely to move to the inner surface 1A side of the winding portion 12 through the hole 12A of the winding portion 12. Therefore, when the second attachment portion 31B moves in such a manner, it is difficult for the user to pass the second attachment portion 31B through the hole 12A again.

  (6) The loop 22 is formed of a material that can provide a soft touch to the user. For this reason, even if the loop 22 touches the skin when the leg pillow 1 is attached to the crus 100, the user is less likely to feel discomfort than when the loop is formed of a hard material. In addition, a significant effect can be obtained as compared with the case where a loop of a hook-and-loop fastener having a normal hardness is attached to the inner surface 1A of the winding portion 12.

  (7) The leg pillow 1 can be used for nursing care, for example. Typically, the leg pillow 1 is attached to the care receiver's lower leg 100 in order to suppress the occurrence of pressure sores on the calves and heels. According to the leg pillow 1, the caregiver puts the lower leg 100 of the cared person on the leg covering portion 10 in a state where the leg covering portion 10 is deployed, and then connects the first adjusting portion 20 to the leg care unit. The pillow 1 is attached to the lower leg 100. For this reason, compared with the case where the shape of the leg covering portion is formed in a cylindrical shape, the caregiver can easily attach the leg pillow 1 to the lower leg 100 of the care recipient.
