Description

  [Technical Field] The present invention relates to a foot cover that is worn on a foot when wearing pumps, sandals, etc., to reduce pain in a toe caused by impact or load during walking and to prevent hallux valgus.

  When wearing footwear such as pumps or sandals with high heels, the center of gravity moves forward, and the load is concentrated on the toes and metatarsal head, causing toe pain and slipping of the foot arch while sliding It is easy to invite a hallux valve or to make an octopus. For this reason, there have been provided various insole for foot impact countermeasures and supporters for correcting hallux valgus that are attached to the front part of the sole when wearing shoes or sandals.

No. 2913192 Utility model registration No. 315858

The previously proposed Hallux valgus countermeasure supporters of Patent Documents 1 and 2 described above are correction tools dedicated to hallux valgus treatment with a cushion attached between the thumb and the second finger, and are not worn for people who are not hallux valgus. Absent. For this reason, wearing this will make the foot thick, making it difficult to wear it on pumps with thin heads. Also, footwear with a nose such as Ben Her cannot be worn because there is a cushion between the fingers. In addition, sandals and the like have a problem in appearance as a supporter for correction.
An object of the present invention is to provide a foot cover that solves this problem and that can be sufficiently expected to prevent hallux valgus without increasing the thickness.

A first device of the present invention for solving the above-mentioned problems is as follows with a foot cover as set forth in claim 1.
A main body formed of a ring-shaped belt, and a connecting portion for separating a portion for inserting the thumb and a portion for inserting the remaining four fingers together into one opening of the main body; A cushion is provided in a portion corresponding to the metatarsal bone, and a slip stopper is provided in a portion corresponding to the outer sole of the main body.

A second device of the present invention for solving the above-mentioned problem is as follows, with a foot cover as set forth in claim 2.
The top cloth of the cushion uses an antibacterial cloth, the elastic material in the middle of the cushion is made of polyurethane foam having a hardness of 20 to 23, and the bottom material is made of a polyurethane sheet material. In this configuration, a cushion of a laminate composed of three layers polymerized using a thickness of 1.3 mm to 1.7 mm is provided.

A third device of the present invention for solving the above problem is a foot cover as described in claim 3 as follows.
In order to correspond to the shape of the middle part of the metatarsal bone, the cushion has a mountain shape and a thickness and provides a manufacturing method.
In the manufacturing method, the upper part is a cloth, the middle part is an elastic material, and the bottom material is a three-layer laminate of a flat sheet of elastic material. Then, the structure is taken out from the mold and cut with a mold along the shape of the bottom surface.

Since the foot cover of the present invention is configured as described above, the following effects can be obtained.
(1) By bridging the finger between the thumb and the second finger and providing a connecting portion with a cloth, there is an effect of spreading the gap between the fingers and preventing hallux valgus.
(2) By providing a cloth by bridging between fingers, there is an effect of reducing pain caused by contact friction between the toes and the umbilical cords or a pressure that occurs during walking with footwear with ligaments such as Benher.
(3) A finger is fixed by partitioning fingers. Furthermore, the insertion hole part is squeezed and tightened using a flat elastic rubber for the insertion part of the thumb, the part where the second to fifth fingers are inserted together and the foot insertion hole part of the foot cover of the present invention. Thus, the finger is further fixed, and the foot cover is difficult to be detached from the foot during walking and the cushion position is stabilized.
(4) Since the fingertip does not have a thickness, it can be attached to a pump with a thin head to prevent hallux valgus.
(5) The material of the foot cover cloth is not limited as long as it is stretchable and breathable. For example, the use of a floral stretch lace has an excellent appearance.
(6) By providing a cushion in the inner part corresponding to the middle part of the metatarsal bone, there is an effect of preventing the hallux valgus by regenerating the lateral arch and the vertical arch on the sole.
(7) The front cloth on the upper surface of the cushion is a part that directly contacts the back of the foot, and can be used hygienically by making it an antibacterial cloth.
(8) The elastic material in the middle of the cushion is made of polyurethane foam with hardness 20 to 23, and the impact of the load caused by walking is rebounded and bounced to lighten the return of the foot. Has the effect of
(9) The bottom material of the cushion is a polyurethane foam sheet, and a thickness of 1.3 mm to 1.7 mm is used, but 1.5 mm is preferable, and the effect of repelling the sinking of the middle elastic material due to body weight is not absorbed. There is.
(10) The above three-layer cushion can reduce foot fatigue during walking by reducing the return of the foot by bouncing by repelling the load and impact of the sole. It also has the effect of preventing octopus on the soles.

It is the Example at the time of mounting | wearing. This is a description of the type of skeleton and foot arch when standing on high heels. It is explanatory drawing of a correct skeleton and a foot arch.

Embodiments of the present invention will be described with reference to the drawings.
1 shows a perspective view of a foot cover 6 of the present invention, FIG. 2 shows a cross-sectional view of 4a, 4b, and 4c of FIG. 1, and FIG. 3 shows a cross-sectional view of FIG.
The foot cover 6 is attached to the forefoot side excluding the thumb A and the second to fifth fingers B in FIG. 6. The foot C is inserted through the foot insertion hole 9 to insert the thumb insertion hole 1. The thumb A is inserted from the second finger, and the second finger is inserted from the second finger through the fifth finger insertion hole 2 and the fifth finger B is inserted.
In the present embodiment, the foot cover 6 for the right foot will be described, but the same applies to the left foot that is symmetrical.

  As shown in the cross-sectional view of FIG. 2, the cushion 4 in FIG. 1 is a laminate composed of three layers. The upper part 4a is an antibacterial cloth made of woven fabric, the middle part 4b is an elastic material of hardness 20 to 23 made of urethane foam, and the bottom part 4c is made of a urethane foam sheet having a thickness of 1.3 mm to 1.7 mm. The cushion 4 is a 3D three-dimensional mold that is compressed and heated to form a three-dimensional shape corresponding to the sole shape.

  The cushion 4 of FIG. 1 is provided in the inner part of the foot cover 6 corresponding to the middle part of the metatarsal, and has a mountain shape with a gentle inclined surface along the arch on the back side of the metatarsal as shown in FIG. . In FIG. 2 of this embodiment, the thickness of the center of the bulging portion is 7 mm at the maximum, and the foot width direction is 44 mm.

  The front cloth 4a in FIG. 2 is a sanitary antibacterial cloth because it directly contacts the middle part of the metatarsal bone of the sole.

The elastic material 4b in FIG. 2 is made of a polyurethane foam having a hardness of 20 to 23, and more preferably a polyurethane foam having a hardness of 22 is used. The shocking pressing force repeatedly received during walking is bounced by the high repulsive force of an elastic material having a hardness of 20 to 23 to lighten the return of the foot to ease the movement of the foot and reduce the fatigue of the foot.
If the elastic material 4b has a hardness of 20 or less, the density of the elastic material is low, it contains a lot of air, it is soft and weak in elasticity, and when a load is applied, the repulsive force is small and it will sink and will not bounce. On the other hand, when the hardness is 23 or more, the elastic material has a high density and does not allow air to enter. Therefore, when a polyurethane foam having a hardness of 20 to 23 is used, it does not sag even when a load is applied. Furthermore, since the soles are soft, if the elastic material is too hard, it is not preferable because the sole portion that comes into contact hurts.

The bottom surface portion 4c in FIG. 2 is a flat hard sheet made of a urethane foam sheet and has a thickness of 1.3 mm to 1.7 mm. The thickness of 1.3 mm to 1.7 mm with respect to the elasticity of the elastic material 4b can resist the pressing force, so that the elastic material 4b is not absorbed on the sole side and the bounce can be held.
The urethane foam sheet 4c is for assisting in bouncing the elastic material 4b by stopping sinking when the load of the elastic material 4b is applied. The urethane foam sheet 4c has a thickness of 1.3 mm to 1.7 mm. If the thickness is reduced, when the load is applied to the elastic member 4b, the elastic material 4b sinks to the back of the foot and the bounce becomes weak. Further, if the thickness is made thicker than 1.3 mm to 1.7 mm, the cushion 4 becomes too thick and when attached to the foot cover 6, the foot cover 6 becomes thick and cannot be attached to a shoe with a thin head. Furthermore, the inner side surface portion corresponding to the middle part of the sole metatarsal bone is higher than the sole arch, the sole floats, and the center of gravity is not fixed and the balance is lost.

  The above-mentioned cushion 4 is a three-layered laminate composed of 4a, 4b, and 4c in FIG. The outer part is cut by superposing on a mold 2 mm outside.

  Inside the foot cover 6 The cushion 4 shown in FIG. 4 is formed by sewing the center portion of the bottom peripheral portion 4c having a width of 2 mm on the outer peripheral edge to the center portion corresponding to the metatarsal bone 7 inside the foot cover 6 with a stretchable nylon thread.

The shape and material of the main body 6 are not particularly limited, and may have other configurations as long as the effects of the present invention are not hindered. FIG. 8 shows an embodiment using a floral stretch lace.

  The thumb insertion hole 1 and the second finger through the fifth insertion hole 2 and the foot insertion hole 8 in FIG. 6 use a flat elastic rubber and are sewn and edged with elastic nylon thread. The toe insertion hole may individually bridge the thumb to the fifth finger. FIG. 8 shows an embodiment in which a decorative flat rubber is used for the insertion holes 1, 2, and 8.

FIG. 9 shows how the toes stand when wearing high heels without wearing the foot cover of the present invention. As shown in FIG. 9, the load area portion is roughly classified into three types, and is shifted in the direction indicated by the thin arrow 10b by the load portion indicated by the thick arrow 10a. When high heels are worn, the arch collapses regardless of the center of gravity deviation 10b.
The problems incurred when wearing the high heels are that the pressure on the toes increases due to the deformation of the toes, the foot slides in the direction of the toes with pain, the toes are further tightened, the gap between the toes disappears, and the toes move The narrower range causes poor circulation and worsens coldness and swelling. Since the heel is thin and unstable, the muscles work excessively to prevent sprains and the muscles from the legs to the waist get tired. In addition, twist is transmitted from the shin to the knee, leading to knee deformation and O-legs. The torsion of the shin is also transmitted to the pelvis and puts a burden on the lower back, and the skeleton gradually becomes distorted, causing back pain.
The present invention solves the above problems and realizes the correct skeleton and foot arch of FIG. 10 by providing a cushion on the inner side corresponding to the middle part of the metatarsal bone, a partition cloth between the thumb and the second finger, and preventing slipping on the back surface. It is a foot cover that can be worn when wearing high heels. When the foot cover of the present invention is mounted, a correct skeleton and foot arch are realized as shown in FIG.
