Description

  The present invention relates to a foot supporter suitable for being worn during walking.

  Walking is an aerobic exercise by walking. Many people enjoy walking for the purpose of improving their constitution, eliminating lack of exercise, and relieving stress. Walking is less suitable for people in a wide range of age groups because it places less burden on the body than running.

However, walking for a long time is not preferable because the impact at the time of landing is repeatedly applied to the joint.
SUMMARY OF THE INVENTION An object of the present invention is to provide a foot supporter that can be worn during walking, and that can mitigate an impact during landing. Another object of the present invention is to provide a foot supporter with a good wearing feeling.

  The foot supporter of the present invention has a main body configured by integrating a sole portion that comes into contact with the sole, an ankle portion that wraps the ankle, and an instep portion that covers the instep, and the fifth base is exposed. Comprising an opening formed in the main body and a stretchable ankle belt wound around the ankle portion, and the sole portion is composed of a soft laminated sheet including at least three layers of an outer layer, a middle layer, and an inner layer, The middle layer is partially thickened to constitute an impact absorbing portion.

  Since the foot supporter according to the present invention includes the impact absorbing portion at the bottom of the foot, the impact at the time of landing during walking can be alleviated and the influence on the joint can be reduced. Also, since the ankle can be fixed by the ankle belt, it is difficult to sprain the ankle during walking. Furthermore, because the Gojo is exposed, the Gojo can be moved freely. As a result, the landing during walking is stable and difficult to fall.

  In addition, the foot supporter of the present invention integrates the impact absorbing portion and the sole by using a partially thick laminated sheet for the sole. Therefore, compared with the case where the shock absorbing part prepared separately is fixed to the sole by stitching or adhesion, the discomfort felt by the wearer on the sole is small, and a comfortable wearing feeling can be obtained. Therefore, even when walking for a long time, it is difficult to cause pain in the sole.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, terms indicating specific directions and positions (for example, “up”, “down”, “right”, “left” and other terms including those terms) are used as necessary. . The use of these terms is to facilitate understanding of the invention with reference to the drawings, and the technical scope of the present invention is not limited by the meaning of these terms. Moreover, the part of the same code | symbol which appears in several drawing shows the same part or member.

  The foot support 1 illustrated in FIGS. 1 and 2 is configured by integrating a sole portion 20 that contacts the sole, an ankle portion 40 that wraps the ankle, and an instep portion 30 that covers the instep. A main body 10 is provided. By configuring the main body 10 from three members, the sole portion 20, the ankle portion 40, and the instep portion 30, it is possible to obtain the main body 10 that fits more in the shape of the foot. Note that the sole part 20, the ankle part 40, and the instep part 30 can be integrated by, for example, sewing. The toe portion of the main body 10 is formed with an opening 60 for exposing the gourd. Further, the sole portion 20 of the main body 10 is provided with an impact absorbing portion 52 on the inner surface 22.

  As shown in detail in FIGS. 3 and 4, the sole portion 20 is formed of a soft laminated sheet 50 including at least three layers of an outer layer 54, an intermediate layer 56, and an inner layer 58. The outer layer 54 is disposed on the outer surface 24 side of the sole 20, and the inner layer 58 is disposed on the inner surface 22 of the sole 20. As shown in FIG. 4, the middle layer 56 is partially thickened to constitute the shock absorbing portion 52 of the sole portion 20.

  In particular, as shown in FIG. 3, the shock absorbing portion 52 has a heel impact absorbing portion 521 formed at a position corresponding to the heel root, and a heel impact absorbing portion 522 formed at a position corresponding to the heel. Are preferably provided. The load applied to the heel and the heel root during walking is larger than other parts. Therefore, it is preferable that the impact on the joint is reduced by absorbing the impact of the heel and the base of the heel.

As shown in FIG. 1, it is preferable to provide a belt-like member 66 extending between the instep part 30 and the sole part 20 in the opening 60. When the foot supporter 1 is mounted, the belt-like member 66 passes between the mother heel and the second heel. By providing the belt-like member 66, it is possible to prevent the foot supporter 10 from shifting in the heel direction during walking. In addition, it is possible to expect the hallux valgus to be suppressed by separating the main hook and the second hook by the belt-like member 66. In addition, when the mother heel and the second heel are separated from each other, force is easily applied to the toes, so that the landing stability is improved.
One method for forming the belt-like member 66 is to provide a belt-like protrusion (for example, reference numeral 66 in FIG. 3) on the instep 30 and the sole 20 and stitch them together.

  Note that the opening 60 is divided into two parts, a limb opening 62 and a heel opening 64, by a band-shaped member 66. When the foot supporter 1 is mounted, the opening 60 is separated from the limb opening 62. The second and fifth cages other than the mother kite are exposed from the kite opening 64.

  As shown in FIG. 1 and FIG. 2, if another shock absorbing portion (shock absorbing portion for Achilles tendon) 48 is provided on the inner surface of the rear side 402 of the ankle portion 40, the Achilles tendon can be protected during walking. Therefore, it is preferable.

  As shown in FIG. 1, it is preferable that the ankle portion 40 of the main body 10 for covering the ankle can be easily inserted into the foot supporter 1 when the front side 401 can be separated into left and right. In addition, it is preferable that the ankle part 40 can be fixed after the foot is inserted into the foot supporter 1 because the foot supporter 1 is less likely to be displaced. As a method for fixing the separated ankle part 40, for example, the front side 401 of the ankle part 40 is provided with left and right flaps 44 and 46 that can be overlapped with each other so that the flaps 44 and 46 can be detachably engaged. There is a way to configure. As shown in FIG. 1, when the surface tape is fixed to each of the outer surface of the left flap 44 and the inner surface of the right flap 46, the left flap 44 and the right flap 46 can be detachably engaged.

  As shown in FIGS. 1 and 2, the foot supporter 1 includes a stretchable ankle belt 70 that is wound around the ankle portion 40. By fixing the ankle with the ankle belt, there is an effect of preventing an injury that twists the ankle while walking. In addition, since the extension and contraction of the tendon around the ankle can be assisted by the ankle belt, there is also an effect that the walking is easy.

  The ankle belt 70 can be composed of a single elastic belt, but as shown in FIG. 2, the ankle belt 70 is preferably composed of a pair of left and right belts 72 and 74. For example, when the ankle belt is wound obliquely forward from the vicinity of the heel on the back side 402 of the ankle portion 40 toward the front side 401 of the ankle portion 40 in order to enhance the ankle fixing effect, Prone to wrinkles and sagging on the front and back of the ankle. On the other hand, if a pair of left and right (two) elastic belts are used, the left and right belts can be switched between the front side and the rear side of the ankle, so that wrinkles and sagging can be eliminated.

  FIG. 2 shows an example of an ankle belt 70 using a pair of stretchable belts. One end of the left belt 72 and one end of the right belt 74 are fixed to the outer surface of the rear side 402 of the ankle portion 40. When the foot supporter 1 is mounted, the other end of the left belt 72 is wound around the left side of the ankle 40 to the front side 401 of the ankle 40, and the other end of the right belt 74 is connected to the ankle. 40 is wound around the right side of 40 to the front side 401 of the ankle 40. In this embodiment, a surface tape (hook side) is fixed to the other ends of the left belt 72 and the right belt 74, and a loop side surface tape is fixed to the outer surface of the front side 401 of the ankle 40 (the surface is fixed). You may use a looped fabric). Thereby, the other end of the left side belt 72 and the other end of the right side belt 74 can be detachably engaged at an arbitrary position on the outer surface of the front side 401 of the ankle portion 40.

With reference to FIGS. 5 to 7, a procedure for mounting the foot supporter 1 of the present embodiment will be described.
With the left flap 44 and the right flap 46 on the front side 401 of the ankle part 40 separated, the foot is inserted into the main body 10 of the foot supporter 1. And the strip | belt-shaped member 66 is inserted between the main rod and the second rod, and the main rod is exposed from the opening portion 62 for the main rod, and the second to fifth rods are respectively exposed from the opening portion for the fourth rod 64 ( FIG. 5).

Next, the left side flap 44 and the right side flap 46 are overlapped in this order and fixed with a surface tape, and the front side 401 of the ankle 40 is closed. Note that the order in which the left side flap 44 and the right side flap 46 are overlapped may be reversed. In this case, the fixing position of the face tape is appropriately changed.
Then, the left belt 72 and the right belt 74 fixed to the rear side 402 of the ankle portion 40 are extended from the left side and the right side of the ankle toward the front side (FIG. 6). In order to enhance the ankle fixing effect, the left belt 72 and the right belt 74 are preferably wound obliquely forward from the vicinity of the heel toward the front side 401 of the ankle portion 40.

On the front side 401 of the ankle portion 40, the other ends of the left belt 72 and the right belt 74 are overlapped in order and fixed with a face tape (FIG. 7). At this time, when the right flap 46 is fixed to the upper side of the left flap 44 as shown in FIG. 6, it is preferable that the left belt 72 is fixed to the right flap 46 and the right belt 74 is fixed thereon. By pulling the right flap 46 by the left belt 72, the ankle can be fixed more effectively. When the stacking order of the right flap 46 and the left flap 44 is reversed, that is, when the left flap 44 is fixed to the upper side of the right flap 46, the right belt 74 is fixed to the left flap 44, The left belt 72 is preferably fixed on the top.
Normally, the other ends of the left belt 72 and the right belt 74 are directly fixed to the front side 401 of the ankle portion 40. However, in order to increase the degree of freedom of the fixing position, as shown in FIG. It is desirable that the other end of the other belt can be fixed to the surface of the belt. For example, hook-side surface tapes may be fixed to the other ends of the left belt 72 and the right belt 74, and loop-side surface tapes may be fixed to the outer surfaces of the left belt 72 and the right belt 74.

  In addition, when putting on shoes, you may wear socks on this foot supporter 1, but in summer when it is easy to sweat, you may wear shoes directly without wearing socks.

Below, the material suitable for each structure is explained in full detail.
<Main body 10>
The main body 10 is preferably made of a different material depending on the part. The following description will be divided into the sole portion 20, the instep portion 30, and the ankle portion 40.

(Sole 20)
The sole 20 is formed from a soft laminated sheet 50 including at least three layers of an outer layer 54, an intermediate layer 56, and an inner layer 58.
The outer layer 54 is preferably formed from a polyurethane sheet obtained by heating and compressing foamed polyurethane. Since polyurethane is resistant to heat, there is an advantage that it does not easily deteriorate even if the outer surface 24 of the sole 20 receives friction during walking. Moreover, since the foamed polyurethane is thermocompression-bonded to obtain a sheet having an appropriate elasticity, it is advantageous in that the shape of the foot supporter can be maintained to some extent.
The middle layer 56 can be formed from a shock-absorbing material such as polyurethane foam.
The inner layer 58 is preferably formed from a material that is comfortable to touch, such as polyester fabric.

  The soft laminated sheet 50 can be integrated (thermocompression bonding) by laminating the outer layer 54, the middle layer 56, and the inner layer 58, and applying pressure while heating using a mold. When this method is used, the shock absorber 52 can be easily formed by using a material for the middle layer 56 having a uniform thickness by thermocompression bonding using a mold having a depression at a position where the shock absorber 52 is formed. There is also an advantage that can be formed. That is, the material for the intermediate layer 56 is heat-molded with the above-described mold, whereby the shock absorbing portion 52 is formed while maintaining the thickness at the recessed portion of the mold, and is compressed by heating at the portion without the recessed portion.

(Instep 30)
The instep portion 30 is preferably formed from a thin power net having excellent stretchability. When inserting a foot, the fabric is stretched so that it is easy to wear, and after mounting, it fits on the back of the foot, so it is easy to wear when wearing shoes from above. Because it is thin, you can feel comfortable even when you sweat while walking.

(Ankle 40)
The ankle portion 40 is also preferably formed from a thin power net having excellent stretchability. Fits to the ankle after wearing, so it is easy to wear when wearing shoes from above. In addition, because it is thin, you can feel comfortable even when you sweat while walking. In addition, it is preferable to use a cloth having a looped surface because it can be used as a substitute for the loop side of the hook-and-loop fastener.

<Ankle belt 70>
The ankle belt 70 is preferably formed from a wide rubber belt. Note that it is preferable to use a rubber belt having a looped surface because it can be used instead of the loop side of the hook-and-loop fastener.

<Shock absorber 48 for Achilles tendon>
The Achilles tendon shock absorbing portion 48 can be formed of a shock-absorbing material such as urethane foam. Moreover, a comfortable wearing feeling can be obtained by sticking a material having a good touch such as a polyester fabric to the surface.
