Description

The present invention relates to indoor shoes that are easy to put on and take off and can assist stable walking, and more particularly to indoor shoes that have a fall prevention effect for a person with deformed legs or a person with weak muscle strength.

For those who have deformed feet, such as neuropathic arthritis such as Charcoal joints, hallux valgus, flat feet, etc., plantar fasciitis (plantar fasciitis), plantar fasciitis, etc., indoors May require indoor shoes to protect the feet and assist in walking. On the other hand, it is desirable that indoor shoes are easy to walk, easy to put on and take off, and do not put excessive pressure on the feet. However, conventional indoor shoes have not been able to sufficiently cope with the deformation of the foot, and have not been easily put on and taken off, and moreover, a custom-made insole (inner sole) that matches the deformed foot cannot be inserted. There were many. Even if the insole can be inserted, the outsole is made of rubber or urethane, which may damage the tatami mats and carpets, and the outsole is thick and heavy. There was a risk of falling because the heel of the insole did not follow the movement of.

For example, Japanese Patent Application Laid-Open No. 2014-226230 discloses indoor shoes for a person who has weak muscular strength and whose ankle is difficult to stabilize due to muscular strength. This indoor shoe supports the ankle with an upper that covers the inner and outer sides of the foot and the heel, and a U-shaped long counter along the heel, and further attaches the first belt and the second belt via a hook-and-loop fastener. By engaging with the outside of the upper and pulling up the long counter, it supports the ankle when walking. However, fixing the ankle with a long counter and a belt in this way causes a problem that the ease of movement and the ease of putting on and taking off required for indoor wearing are impaired. Moreover, because of the structure that rises from the peripheral edge of the sole and covers the inner and outer sides of the foot and the heel with the upper that covers the inner and outer sides of the foot and the heel, the deformed foot when the wearer is accompanied by deformation of the foot. It is difficult to insert and store the insole (top line), and it is also difficult to insert a custom-made insole.

Utility model registration No. 2552604 discloses rehabilitation shoes that retain the function of a rehabilitation orthosis in order to recover from paralytic symptoms of the foot caused by cerebrovascular accidents and the like. In this rehabilitation shoe, the lunar core is brought into close contact with the side of the deformed ankle to correct the inwardly curved varus ankle, and the lunar core is curved to the heel of the instep. The one-sided edge or both-sided edge of the moon-shaped core is extended forward, and the moon-shaped core is inserted into the sole and fixed. However, shoes that cover the sides of the ankle and have a moon-shaped core fixed to the sole are not easy to put on and take off when used as indoor shoes, and it is also difficult to match them with deformed feet.

Japanese Unexamined Patent Publication No. 2014-226230 Utility Model Registration No. 2552604

Therefore, an object of the present invention is indoor shoes that are easy to walk and put on and take off, and even when worn by a person with a disability in the foot, it is possible to cope with deformation of the foot and the like, and stable walking. Is to provide indoor shoes that can assist.

As a result of diligent studies, the present inventors have adjusted the height of the heel of the indoor shoe to be below the ankle of the wearer, preferably to a height at which a part of the wearer's calcaneus is exposed from the heel of the indoor shoe. By arranging counters (moon-shaped cores) with a length from the heel to the bend on both sides of the inner and outer uppers of the indoor shoes, it is easy to walk, put on and take off, and the feet. The present invention has been completed by finding that it is possible to cope with the deformed foot and assist stable walking even when the person wears the deformed foot.

That is, the indoor shoe of the present invention has an insole, an inner upper portion, an outer upper portion, and a heel portion in which the heel side end portion of the inner upper portion and the heel side end portion of the outer upper portion are joined. However, the inner upper part and the outer upper part can be detachably engaged with each other, and counters are provided on both sides of the inner upper part and the outer upper part, respectively, and the counters are provided from the vicinity of the heel side end of the upper part. It has a length close to the flexion position of the wearer's foot, and the height of the heel portion from the insole is the height at which a part of the wearer's calcaneus is exposed from the heel portion.

In one preferred embodiment of the invention, the heel height is such that a portion of the wearer's calcaneus is exposed from the heel of the indoor shoe, for example, at a height of 1 cm to 5 cm from the insole. is there. The length of the counter is the length from the vicinity of the heel side end of the indoor shoe to the vicinity of the bending position of the wearer's foot, for example, 6 cm to 16 cm. The width of the counter near the flexion position of the wearer's foot is 1.2 to 4 times, 2 to 4 times, or 2 to 3 times the width of the counter near the heel side end. ..

In one preferred embodiment of the invention, the counter is disposed between the front and back fabrics that make up the inner and outer uppers and is not connected to the insole. In one preferred embodiment of the present invention, hook-and-loop fasteners are provided on the inner upper portion and the outer upper portion.

In one preferred embodiment of the present invention, an insole is inserted in the indoor shoe. The insole may be a custom-made insole that matches the deformed foot of each wearer.

It is a top view (A) and a bottom view (B) which show schematicly the indoor wear by one Embodiment of this invention. FIG. 5 is a schematic perspective view of indoor shoes according to one embodiment of the present invention, showing a state in which the inner upper portion and the outer upper portion are engaged with each other. It is the schematic perspective view which shows the bending part of the indoor wear corresponding to the bending position of the wearer's foot. FIG. 3A is a schematic perspective view (A) of indoor shoes with an insole inserted according to one embodiment of the present invention, and is a cross-sectional view (B) thereof.

The indoor shoe of the present invention has an insole portion, an inner upper portion, an outer upper portion, and a heel portion formed by joining the heel side end portion of the inner upper portion and the heel side end portion of the outer upper portion, and has an inner upper portion. And the outer upper part can be detachably engaged. In addition, counters are provided on both sides of the inner upper portion and the outer upper portion, respectively, and the counter has a length from the vicinity of the heel side end portion of the upper portion to the vicinity of the flexion position of the wearer's foot, and the insole portion. The height of the heel from the heel is the height at which a part of the wearer's calcaneus is exposed from the heel.

An engaging portion is provided on the inner upper portion and the outer upper portion of the indoor shoe of the present invention, and the inner upper portion and the outer upper portion can be engaged with each other by the engaging portion. When the medial and lateral uppers are engaged, the cuffs formed by the medial, lateral, and heels do not cover the wearer's heel, and part of the calcaneus is worn indoors. Exposed from the heel. Further, in the indoor shoes of the present invention, preferably, the engaging portion is provided directly on the inner upper portion and the outer upper portion, and when worn, the inner upper portion and the outer upper portion are engaged without using a belt. The indoor shoes of the present invention do not fix the instep or ankle with a belt, but flexibly adjust the engaging position of the upper portion to correspond to the deformed foot.

In the indoor shoes of the present invention, the toe portion of the wearer is not covered, preferably when the inner upper portion and the outer upper portion are engaged. Since the toe part of the indoor shoes is open, it is easy to put on and take off, and it is possible to respond more flexibly to deformed feet.

The indoor shoes of the present invention can be worn according to the deformed foot by changing the position where the inner upper portion and the outer upper portion are engaged. The engaging portion is not particularly limited, and may be a button, a string, or the like, but is preferably a hook-and-loop fastener. The hook-and-loop fastener is easy to put on and take off, and the engaging position can be freely changed.

The height of the heel portion of the indoor shoe of the present invention is lower than the height of the ankle portion of the wearer's foot, and is the height at which a part of the calcaneus is exposed from the heel portion. The indoor shoes of the present invention do not fix and support the wearer's ankle, but make walking easier by opening the circumference of the wearer's ankle. The height of the heel portion is, for example, 5 cm or less, 4 cm or less, 3 cm or less, or 2 cm or less, and 1 cm or more, or 2 cm or more from the insole portion. The indoor shoes of the present invention not only make it easier to put on and take off by lowering the height of the heel portion, but also make it easier to spread the indoor shoes in the horizontal direction, so that they can respond more flexibly to deformed feet. Can be done.

The problem with lowering the height of the heel is that the heel of the indoor shoe is more likely to come off the wearer's heel when walking, resulting in unstable walking. The indoor shoes of the present invention solve this problem by providing counters on the inner upper portion and the outer upper portion, respectively. By providing counters with a length from the vicinity of the heel side end to the vicinity of the flexion position of the wearer's foot in each of the inner upper portion and the outer upper portion, the flexion portion of the indoor foot can be aligned with the flexion position of the foot. As a result, even when the foot is bent, the part where the counter is provided follows the foot, and the heel part is hard to come off from the foot by stepping back. Therefore, the indoor shoes of the present invention do not move like slippers or sandals in which the movement of the wearer's feet is not accompanied by the movement of the footwear, and stable walking is possible. The length (longitudinal direction) of the counters extended on both sides of the indoor shoes varies depending on the size of the indoor shoes, but is, for example, 6 cm or more, 8 cm or more, or 10 cm or more, 16 cm or less, 14 cm or less, or 12 cm or less. Is.

The width of the counter near the flexion position of the wearer's foot (the length in the direction perpendicular to the longitudinal direction of the counter) is preferably wider than the width of the counter near the heel side end. For example, the width of the counter near the flexion position of the wearer's foot is 1.2 times or more, 1.5 times or more, or twice or more, and 4 times or less the width of the counter near the heel side end. It is 3 times or less, or 2.5 times or less. By making the width near the flexion position of the wearer's foot wider than the width near the heel side end of the counter, the wearer's foot can be supported more stably near the flexion position.

The counter is arranged on the surface of the front or back fabric of the upper portion, or between the front fabric and the back fabric of the upper portion. Preferably, the counter is disposed between the front and back fabrics of the upper portion. The means for arranging the counter on the upper portion is not particularly limited, and for example, the counter can be attached to the upper portion by adhesion, suturing, or the like. In the indoor shoes of the present invention, the counter is preferably not connected to the insole. When the counter is connected to the insole, the horizontal spread of the indoor shoes is restricted, which prevents the deformed foot from being accommodated.

When wearing the indoor shoes of the present invention, the wearer first places the foot on the insole portion of the indoor shoes, then overlaps the inner upper portion and the outer upper portion so as to wrap around the instep, and engages the inner upper portion. Engage with the engaging portion of the portion and the outer upper portion. At that time, the engagement position is determined by the size, deformation, etc. of the foot, and the engagement position is adjusted by the engagement portion to engage. Since the indoor shoes of the present invention have a low heel portion and are worn so as to wrap the inner upper portion and the outer upper portion, it is possible to flexibly respond to the size, deformation, etc. of the foot. Therefore, unlike indoor shoes in which the upper portion rises from both sides of the insole portion and the heel portion is high, it is not necessary to insert the foot into the mouth when wearing the foot, and even a deformed foot can be easily worn.

Since the indoor shoes of the present invention have a flexible structure whose size can be adjusted, they are also suitable for inserting an insole. The insole can be a custom-made insole that matches the wearer's feet, and even an insole with a thickness of about 5 mm can be accommodated.

The inner upper portion and the outer upper portion may be composed of different fabrics, or may be composed of one fabric. For example, in the indoor shoes of the present invention, the insole portion is attached to a piece of cut fabric, the portion corresponding to the inside of the foot across the insole portion is the inner upper portion, and the portion corresponding to the outer side of the foot is the outer upper portion. May be. The heel-side end of the inner upper and the heel-side end of the outer upper can be joined by any means. For example, they may be joined by adhesion, suturing, or the like. The indoor shoes of the present invention are not limited to the form in which the heel-side end of the inner upper portion and the heel-side end of the outer upper portion are previously joined, and the ends of the inner upper portion and the outer upper portion face each other when worn. It also includes a form of engaging and joining with fasteners, wire fasteners, buttons and the like.

The upper portion may have a structure in which the front fabric and the back fabric are overlapped. The structure and material of the upper portion can be the structure and material usually used for indoor shoes, and are not particularly limited. For example, polymer sheets, fabrics made of natural or synthetic fibers, natural or synthetic leather and the like can be mentioned. From the viewpoint of protecting the feet, materials such as natural rubber and synthetic rubber (isoprene rubber, chloroprene rubber, butadiene rubber, styrene butadiene rubber, nitrile rubber, butyl rubber, urethane rubber, ethylene propylene rubber, acrylic rubber, etc.) are used for the outer fabric. You may use it. As the lining fabric, a mesh fabric may be used from the viewpoint of improving breathability. Further, both the front fabric and the back fabric may be mesh fabrics.

The indoor shoes of the present invention preferably have a ground contact portion (outsole) on the back surface of the indoor shoes at a position corresponding to the insole. By providing a grounding portion, it is possible to prevent wear of indoor shoes. If the thickness of the ground contact portion is thick, it may cause a fall. Therefore, the thickness of the ground contact portion is preferably 5 mm or less, 3 mm or less, 0.5 mm or more, or 1 mm or more.

The material of the counter is not particularly limited as long as it has strength and flexibility that can effectively support the wearer's foot. For example, synthetic polymers, natural polymers, metals, alloys and the like can be used.
