Description

The present invention relates to footwear having an upper portion that covers the instep.

There are foot diseases such as hallux valgus with the hallux (first toe) deformed to the side of the small toe (fifth toe) and hallux valgus with the hallux deformed to the side of the toe. It has been reported that more than one in three women over the age of 65 develop hallux valgus. Taking this hallux valgus as an example, the first metatarsal bone spreads inward, and the bones of the first metatarsal bone and the hallux are deformed in a dogleg shape. The head of the first metatarsal bone protrudes inward. In the bunion, the head of the fifth metatarsal bone protrudes outward. The affected area that pops out inward or outwards receives irritation such as hitting shoes, causing subcutaneous synovitis, red swelling, and pain.

Therefore, as footwear for those suffering from hallux valgus or hallux valgus, footwear having an opening on the side of the upper part covering the instep, on the toe side (for example, Patent Document 1), or the affected part. A footwear (for example, Patent Document 2) in which the footwear is covered with a rubber sheet has been proposed.

In the footwear proposed in Patent Document 1, the affected part that protrudes is exposed, it is cold in winter, and the fashionability is greatly inferior. In that respect, in the footwear proposed in Patent Document 2, the affected part is always covered with a rubber sheet, it is not cold even in winter, and the rubber sheet is tightened with a belt body to improve fashionability.

Japanese Unexamined Patent Publication No. 2012-407 Utility Model Registration No. 3171220 Gazette

However, a person who has severely injured subcutaneous synovitis in the affected area feels severe pain even if the rubber sheet hits the affected area, and it is impossible to tighten it with a belt body.

In view of the above circumstances, it is an object of the present invention to provide footwear that can be worn even by a person whose subcutaneous synovitis is seriously injured.

Footwear that solves the above purpose
Footwear with an upper that covers the instep
The upper portion has an opening on the side portion on the toe side.
A covering member that covers the opening and can adjust the contact pressure to the foot portion located in the opening is provided.
The covering member can change the position of the tip portion on the left side or the right side to an arbitrary position when adjusting the contact pressure, and the position of the tip portion is fixed after the position of the tip portion is changed. It is characterized in that it is to be done.
also,
The opening is an opening from the position of the metatarsal interphalangeal joint of the hallux to a part of the hallux.
The upper portion may be characterized in that it covers the entire nail portion of the hallux.
also,
The covering member may be characterized in that a stretchable portion made of a material having higher elasticity than all the materials constituting the upper portion is provided at a portion in contact with the portion.
also,
The covering member may be characterized in that a cushioning material is provided on the outer side of the stretchable portion in the thickness direction at a distance from the stretchable portion.
also,
The covering member may be characterized in that it is removable separately from the upper portion.
Moreover,
Footwear with an upper that covers the instep
The upper portion has an opening on the side portion on the toe side.
Covering the opening may be characterized in that an adjustable covering member the contact pressure to the site of the foot located opening.

According to this footwear, there is no member that always covers the opening, and the covering member may come into direct contact with the foot portion, but the contact pressure can be set to zero. Therefore, it can be worn even by a person with severe subcutaneous cystitis.

The opening may be provided only on the inner side (hallux side), may be provided only on the outer side (small toe side), or both inside and outside. It may be the one provided in. Further, the opening is covered only by the covering member.

also,
The covering member is preferably characterized in that the portion in contact with the portion is made of a material having higher elasticity than all the materials constituting the upper portion.

Since the portion is made of such a highly elastic material, pain can be significantly reduced even if the portion comes into contact with the portion.

As the material having high elasticity, for example, a woven fabric using spandex or a non-woven fabric using etrustomer resin can be used.

The covering member may be made of a material having higher elasticity than all the materials constituting the upper portion around the portion in contact with the portion. That is, at least the portion of the covering member that comes into contact with the portion may be made of a material having higher elasticity than all the materials constituting the upper portion.

also,
The opening may be characterized in that it opens from the position of the metatarsal internode joint of the toe to a part of the toe.

When subcutaneous synovitis becomes severe, inflammation may extend to the toes, and a large opening is preferable. On the other hand, if the opening is large, it may be cold in winter or inferior in fashionability, but if the opening is covered with the covering member so as not to touch the foot portion (the contact pressure is 0). It can reduce the cold and guarantee fashionability to some extent. Further, if the portion is made of a highly elastic material, it can be brought into contact with the portion, it is not cold, and fashionability can be improved.

The part of the toe may be the base of the toe. In addition, it may be opened to the toe side beyond the base of the toe. That is, the opening may be an opening from the position of the metatarsal internode joint of the toe to at least the base of the toe.

Further, the opening may be an opening from the position of the metatarsal internode joint of the toe to the position of the interphalangeal joint of the toe.

More specifically, it is an opening from the position of the metatarsophalangeal joint of the toe to a part of the toe (for example, the interphalangeal joint (proximal interphalangeal joint in other toes)). It may be an opening from the position of the metatarsophalangeal joint of the small toe to a part of the small toe (for example, the distal interphalangeal joint).

also,
The covering member may be characterized in that a cushioning material is provided at a position covering the portion.

Even when an external force is applied to the foot portion (for example, when the foot is hit), the cushioning material can reduce the force.

also,
The covering member may be characterized in that it is removable.

The covering member can cover the opening while keeping the contact pressure at 0, but when it is more important than coldness and fashionability to prevent the covering member from touching the affected part with some beat. It is most certain that the covering member is removed.

also,
The covering member may be characterized in that it can double-cover the opening.

By covering it twice, it protects the foot part and also protects against the cold.

The footwear of the present invention can be worn by a person who has severely injured subcutaneous synovitis.

Both the inner covering member 141 and the outer covering member 142 shown in FIG. 2 are opened in a flat state, the back surfaces 141b and 142b are shown, respectively, and the inner opening 121 and the outer opening 122 are open. be.

In the right foot RF suffering from hallux valgus, the first metatarsal MB1 spreads inward, the bones of the first metatarsal MB1 and the hallux FT1 are deformed into a dogleg shape, and the head MB1t of the first metatarsal MB1 The part pops out inward and receives irritation such as hitting shoes, causing subcutaneous synovitis and becoming the affected part AFA and swollen red. In FIG. 2, the red and swollen affected area AFA is shown in black. The affected area AFA shown in FIG. 2 projects inward beyond the inner edge 11e of the bottom portion 11. Although not shown, in the right foot suffering from varus small toe, the fifth metatarsal bone MB5 spreads outward, and the bones of the fifth metatarsal bone MB5 and the small toe FT5 are deformed into a dogleg shape, and the fifth metatarsal bone MB5 is deformed into a dogleg shape. The portion of the head MB5t of the metatarsal bone MB5 protrudes outward.

The inner opening 121 is provided so as to open around the affected area AFA, and the end portion of the inner opening 121 on the toe side is premised on the general size of the foot that matches the size of the shoe 1. Extends to the position of the hallux FT1. That is, the medial opening 121 is opened from the position of the head MB1t of the first metatarsal bone MB1 to a part of the hallux FT1 (base portion BF1). More specifically, the medial opening 121 is the first when the shortest distance from the position of the head MB1t of the first metatarsal bone MB1 to the position of the interphalangeal joint IJ1 of the hallux FT1 is D1. It is designed to open to a distance D1 or more from the position of the head MB1t of the metatarsal MB1 (see the single-point chain line arrow and arc shown in FIG. 2).

The lateral opening 122 is also provided so as to open around the affected portion (not shown) of the bone head MB5t portion of the fifth metatarsal bone MB5, and the end portion of the lateral opening 122 on the toe side is small. It extends to the position of the toe FT5. That is, the lateral opening 122 is an opening from the position of the head MB5t of the fifth metatarsal bone MB5 to the tip of the small toe FT5. Expressed in the same way as the design index using the medial distance D1, the lateral opening 122 extends from the position of the head MB5t of the fifth metatarsal bone MB5 to the position of the proximal internode joint IJ51 of the small toe FT5. When the shortest distance is D2, it is designed to open from the position of the head MB1t of the first metatarsal bone MB1 to a position separated by a distance D2 or more. The outer opening 122 may be opened only to the middle of the small toe FT5 (for example, in front of the nail). More specifically, it may be open only to the position of the distal interphalangeal joint IJ52 of the small toe FT5.

Subsequently, how to use the pair of covering members 14 will be described.

FIG. 3 is a diagram for stepwise explaining how to use the pair of covering members.

In the shoe 1 shown in FIG. 3A, similarly to the shoe 1 shown in FIG. 2, the inner covering member 141 and the outer covering member 142 are opened in a flat state, and both the inner opening 121 and the outer opening 122 are opened. It is in a state of being. Put on shoes 1 in this state. In FIG. 3, the right foot is not shown.

In FIG. 3B, the inner covering member 141 opened in a flat state directly covers the upper portion 12. In FIG. 3B, the inner covering member 141 covers the upper portion 12 so as not to form a gap as much as possible. That is, the inner covering member 141 is in contact with the edge portion 121e (see FIG. 3A) of the inner opening portion 121 in a state as close as possible to the inner opening portion 121, and is covered so as to maximize the contact area with the upper portion 12. ing. In FIG. 3B, the stretch material 150 provided on the inner covering member 141 is shown by a dotted line. The inner opening 121 is covered with this stretch material 150. Further, the tip portion 141t (outer end portion) of the inner covering member 141 also almost covers the outer opening 122. The tip portion 141t of the inner covering member 141 may cover the entire outer opening 122. In FIG. 3B, the loop surface 1413 provided on the front surface of the inner covering member 141 is shown in dark gray. Further, in FIGS. 3A and 3B, the hook surface 1422 provided on the back surface of the outer covering member 142 is shown in light gray.

In FIG. 3C, the outer covering member 142 that was opened in a flat state covers the inner covering member 141 that covers the upper portion 12. When the outer covering member 142 covers the inner covering member 141, the loop surface 1413 on the front surface of the inner covering member 141 and the hook surface 1422 on the back surface of the outer covering member 142 adhere to each other, and the position of the inner covering member 141 is fixed. Will be done. In this embodiment, the outer covering member 142 has a function of fixing the inner covering member 141. The outer covering member 142 covers the upper portion 12 with the inner covering member 141 sandwiched between them. In FIG. 3C, the outer covering member 142 is covered with the inner covering member 141 covering the upper portion 12 so as not to form a gap as much as possible. That is, the outer covering member 142 is covered so that the contact area with the inner covering member 141 is maximized. The outer covering member 142 covers the outer opening 122 directly or with the tip portion 141t of the inner covering member 141 sandwiched between them, and the tip portion (outer end) 142t of the outer covering member 142 also includes the inner opening 121. It almost covers the inner covering member 141 with the inner covering member 141 sandwiched between them. As shown in FIG. 3C, the inner opening 121 can be doubly covered and the outer opening 122 can also be doubly covered by the pair of covering members 14.

The usage of the pair of covering members 14 described with reference to FIG. 3 is for a person with a mild bunion of the right foot. In patients who have had the affected area AFA projecting inward beyond the medial edge 11e of the bottom 11 (see FIG. 2), resulting in subcutaneous synovitis and swelling, between the medial covering member 141 and the medial opening 121. With a gap, the inner covering member 141 is put on the upper portion 12 and fixed by the outer covering member 142. By adjusting the amount of the gap, the contact pressure of the stretch material 150 with the affected part can be adjusted. That is, the larger the amount of the gap, the smaller the contact pressure. If the outer covering member 142 is put on the inner covering member 141 to fix the inner covering member 141 in a state where the stretch material 150 is completely separated from the affected part, the contact pressure of the stretch material 150 with the affected part becomes zero.

A person suffering from hallux valgus is used by first covering the upper portion 12 with the outer covering member 142, covering the outer opening 122 with the stretch material 150 provided on the outer covering member 142, and then covering the outer opening 122 thereof. The hook surface 1412 on the back surface of the inner covering member 141 is adhered to the loop surface of the front surface of the member 142 to fix the position of the outer covering member 142.

The shoe 1 of the present embodiment can be used by both a person suffering from hallux valgus and a person suffering from hallux valgus.

Subsequently, the stretch material 150 will be described by taking the inner covering member 141 as an example, but the same applies to the stretch material 150 in the outer covering member 142.

FIG. 4 is a diagram schematically showing a state when the periphery of the inner window portion is cross-sectionald. In FIG. 4, the upper part of the figure is the front side of the inner covering member 141, and the lower part is the back side of the inner covering member 141. That is, the lower part of the figure is the affected part side.

FIG. 4A shows a cross-sectional view of the inner window portion 1411 of the inner covering member 141 in the shoe 1 shown in FIG.

The base material 1410 of the inner covering member 141 may be made of the same material as the material of the upper portion 12, or may be made of a cloth on which the hook-and-loop fastener can be easily sewn. In FIG. 4, the loop surface 1413 provided on the front surface 141a of the inner covering member 141 is schematically shown in gray. The loop surface 1413 is arranged so as to close the inner window portion 1411 from the front side.

The stretch material 150 is sewn on the outer peripheral portion 1411o of the window portion that surrounds the edge defining the inner window portion 1411 from the back surface side. Therefore, the corner 1411e of the edge defining the inner window portion 1411 is not exposed and is covered with the stretch material 150, and the corner 1411e does not directly touch the affected portion.

The stretch material 150 has higher elasticity than all the materials constituting the upper portion 12. When the upper portion 12 is made of a plurality of materials, the upper portion 12 has higher elasticity than any of the plurality of materials. For example, even when a rubber material is used for a part of the upper portion 12, such as slippers used by elementary school students, the stretch material 150 has higher elasticity than the rubber material. That is, the stretch material 150 has much higher elasticity than the conventional rubber material used for the upper portion 12, and even in terms of thickness, the thickness of the thinnest material among all the materials constituting the upper portion 12 It is less than half the thickness of. Examples of the stretch material 150 include a woven fabric in which two front and back fabrics are connected by a spandex bare yarn, and a non-woven fabric using an etrustomer resin having a thickness of less than 1 mm.

Due to its elasticity, the stretch material 150 can come into close contact with the affected area and wrap the affected area along the shape of the affected area. The rubber material used for a part of the upper part 12 has insufficient elasticity at all, and the patient feels severe pain if it comes into contact with the affected part even a little, but with the stretch material 150, the elasticity is high even if it comes into contact with the affected part. It does not become resistance, it becomes familiar with the affected area, and the pain caused to the patient is greatly reduced. In addition, the cold can be relieved by bringing the stretch material 150 into close contact with the affected area.

FIG. 4B is a cross-sectional view showing a modified example of the inner covering member 141 shown in FIG. 4A. The components having the same names as those used so far will be described with the same reference numerals as those given so far.

In FIG. 4B, the stretch material 150 is arranged in the inner window portion 1411 so as to be sandwiched between the base material 1410 of the inner covering member 141 and the loop surface 1413. In the inner covering member 141 of this modified example, the inner window portion 1411 is larger than the inner covering member 141 shown in FIG. 4A, and the corner 1411e of the edge defining the inner window portion 1411 is less likely to come into direct contact with the affected portion. .. The inner window portion 1411 in this modification is not covered by the loop surface 1413. That is, the loop surface 1413 is provided with a cutout hole 1413h having the same size as the inner window portion 1411 at the position of the inner window portion 1411. Further, a cushion material 1414 is also provided on the inner covering member 141 of this modified example. Examples of the material of the cushion material 1414 include urethane, sponge, and rubber. The cushion material 1414 has a leg portion 1414h. The cushion material 1414 covers the inner window portion 1411 from the inner window portion 1411 on the front side with an interval SP having a length of the leg portion 1414h. That is, the cushion material 1414 is provided at a position that covers the affected portion. However, the cushion material 1414 is separated from the stretch material 150 by a distance obtained by adding the above interval SP to the thickness of the loop surface 1413. Therefore, even if the affected area tightly covered with the stretch material 150 is greatly swollen, the affected area is unlikely to hit the cushion material 1414. Even if the shoes provided with the cushion material 1414 are worn and the area around the inner opening 121 is hit, the cushion material 1414 protects the affected area.

The cushion material 1414 may omit the leg portion 1414h. Further, the outer covering member 142 may have a length sufficient to cover the cushion material 1414, or the outer covering member 142 may be shortened so as not to reach the cushion material 1414. It may be.

FIG. 5 is a plan view showing the shoes of the second embodiment. The components having the same names as those used in the description of the shoes of the first embodiment will be described with the same reference numerals as those given so far. In addition, the differences from the shoes of the first embodiment will be mainly described, and the description overlapping with the shoes of the first embodiment may be omitted. Note that FIG. 5 shows the shoe 1 for the right foot, with the left side of the figure being the inside and the right side being the outside.

In the shoe 1 of the first embodiment, both the inner covering member 141 and the outer covering member 142 are sewn to the bottom portion 11 and cannot be separated from the bottom portion 11. On the other hand, in the shoe 1 of the second embodiment, the pair of covering members 14 are made into one covering member, and this one covering member can be separated from the bottom portion 11.

FIG. 5A shows one covering member 16. One covering member 16 has an inner covering portion 161, an outer covering portion 162, and a connecting portion 163. Since the configuration of the inner covering portion 161 is the same as the configuration of the inner covering member 141 and the configuration of the outer covering portion 162 is the same as the configuration of the outer covering member 142, the description thereof will be omitted. The single covering member 16 shown in FIG. 5A is formed by inserting the inner opening 121 and the outer opening 122, and the connecting portion 163 is located between the inner opening 121 and the outer opening 122. .. That is, the connecting portion 163 is located above the bottom portion 11.

As shown in FIG. 5B, if the one covering member 16 is pulled out inward, the inner opening 121 can be removed through the connecting portion 163 and the outer covering portion 162. The single covering member 16 can also be pulled out to the outside. As described above, the shoe 1 of the first embodiment can also cover the inner opening 121 and / and the outer opening 122 while keeping the contact pressure at 0, but the pair of covering members 14 have some beat. There is a risk of touching the affected area. When the patient places more importance on the fact that the covering member does not touch the affected part than the coldness and fashionability, removing the covering member 16 is the most reliable measure to prevent the covering member 16 from touching the affected part.

In the shoe 1 of the second embodiment, when the patient wears the shoe 1 to which the covering member 16 is attached, the connecting portion 163 is stepped on, but the covering member 16 is the most of the bottom portion 11. It may be inserted under the insole on the upper side.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims. For example, the inner covering member 141 and the inner opening 121 may be provided, and the outer covering member 142 and the outer opening 122 may not be provided. In this case, the back surface 141b of the inner covering member 141 and the upper portion 12 may be adhered to each other by a hook-and-loop fastener. Alternatively, only the outer covering member 142 and the outer opening 122 may be provided, and the back surface 142b of the outer covering member 142 and the upper portion 12 may be adhered by a hook-and-loop fastener.

FIG. 6 is a plan view showing a state in which a shoe having an inner covering member and an inner opening and no outer covering member and an outer opening is worn on the right foot suffering from hallux valgus. FIG. 6 schematically shows the skeleton of the right sole as in FIG. 2. Hereinafter, the same reference numerals as those used in FIG. 2 will be added for description.

In the shoe 1 shown in FIG. 6, the inner covering member 141 is opened in a flat state, and the back surface 141b thereof is shown. The inner opening 121 is in an open state.

Also in FIG. 6, the red and swollen affected area AFA protruding inward beyond the inner edge 11e of the bottom 11 is shown in black.

The medial opening 121 shown in FIG. 6 is the length of this distance D1 when the shortest distance from the position of the head MB1t of the first metatarsal bone MB1 to the position of the internode joint IJ1 of the hallux FT1 is D1. It is formed by an arc whose radius is the radius and whose center is aligned with the bone head MB1t. The medial opening 121 has a larger opening area than the medial opening 121 shown in FIG. 2, and is open to the position of the head MB2t of the second metatarsal bone MB2, and is a part of the hallux FT1 (base portion BF1). ) Is also exposed. The medial opening 121 is not opened to the position of the head MB2t of the second metatarsal MB2, but the position of the two-point chain line marked between the first metatarsal MB1 and the second metatarsal MB2. It may be up to the first metatarsal bone MB1 side.

Further, as the opening area of the inner opening 121 is increased, the stretch material 150 provided on the inner covering member 141 shown in FIG. 6 is also increased. The portion of the upper portion 12 shown in FIG. 6 covered by the inner covering member 141 is a loop surface, and is adhered to the hook surface 1412 of the back surface 141b of the inner covering member 141.

In the shoe 1 shown in FIG. 6, the outer covering member is omitted, but an outer covering member 142 similar to the shoe 1 shown in FIG. 2 may be provided so as to double cover the inner opening 121. When the outer covering member 142 is provided on the shoe 1 shown in FIG. 6, the stretch material 150 for covering the omitted outer opening is not required for the outer covering member 142, but the inner covering member 141 is placed between the inner covering members 141. A stretch material may be provided on the portion that covers the portion 121.
