Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to indoor slippers that are easy to put on and take off and that can assist stable walking, and more particularly to indoor slippers that are effective in preventing falls for people with deformed feet or weak muscles.

People with foot deformities, such as neuropathic arthritis such as Charcot's joint, hallux valgus, flat feet, plantar callus, plantar fasciitis, etc., indoors may need indoor shoes to protect their feet and aid in walking. On the other hand, it is desirable that indoor shoes are easy to walk, easy to put on and take off, and not to put excessive pressure on the feet. However, indoor slippers up to now have not been able to adequately adapt to deformed feet or have been difficult to put on and take off. There were many In addition, even if the insole can be inserted, the outsole made of rubber or urethane may damage the tatami mats and carpets, and the thick and heavy outsole may cause damage to the foot. There was a risk of falling because the heels of the indoor shoes did not follow the movements of the shoes.

For example, Japanese Patent Application Laid-Open No. 2014-226230 discloses indoor slippers for people with weak muscles and difficulty in stabilizing their ankles. These indoor shoes support the ankle with an upper that covers the inside and outside of the foot and the heel, and a U-shaped long counter that runs along the heel. It supports the ankle during walking by engaging with the outside of the upper and pulling up the long counter. However, fixing the ankle with a long counter and a belt in this way poses the problem of impairing the easiness of movement and easiness of putting on and taking off that are required in indoor slippers. Moreover, because of the structure in which the inner and outer sides and the heel of the foot are covered by the upper that rises from the periphery of the sole and covers the inner and outer sides and the heel of the foot, when the wearer is accompanied by deformation of the foot, the deformed foot are difficult to insert and accommodate in the top line, and custom insoles are also difficult to insert.

Japanese Utility Model Registration No. 2552604 discloses a rehabilitation shoe that retains the function of a rehabilitation device for recovering from paralysis of the foot caused by cerebrovascular accident or the like. This rehabilitation shoe is intended to correct an inwardly curved varus ankle by bringing a moon-shaped core into close contact with the side surface of a deformed ankle. One side edge or both side edges of the moon-shaped core are extended forward, and the moon-shaped core is inserted into the sole and fixed. However, when shoes with a moon-shaped core fixed to the sole covering the side of the ankle are used as indoor slippers, they are not easy to put on and take off, and it is also difficult to fit deformed feet.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view (A) and a bottom view (B) schematically showing indoor slippers according to one embodiment of the present invention; 1 is a schematic perspective view of a slipper according to one embodiment of the invention, showing the inner and outer upper portions engaged; FIG. FIG. 4 is a schematic perspective view showing a bent portion of the indoor shoe corresponding to the bent position of the wearer's foot; 1 is a schematic perspective view (A) of indoor shoes with an insole inserted according to one embodiment of the present invention, and its A-A' sectional view (B).

The indoor shoes of the present invention have an inner sole, an inner upper, an outer upper, and a heel formed by joining the heel-side end of the inner upper and the heel-side end of the outer upper, and the inner upper. and the outer upper portion are removably engageable. In addition, counters are provided on both sides of the inner upper portion and the outer upper portion, respectively. The empty heel height is the height at which a portion of the wearer's calcaneus is exposed from the heel.

The inner upper portion and the outer upper portion of the indoor shoes of the present invention are provided with engaging portions, and the inner upper portion and the outer upper portion can be engaged by the engaging portions. When the inner upper part and the outer upper part are engaged, the opening formed by the inner upper part, the outer upper part, and the heel part does not cover the entire heel of the wearer, and a part of the calcaneus is part of the indoor shoe. Exposed from the heel. Further, in the indoor shoes of the present invention, the engaging portions are preferably provided directly on the inner upper portion and the outer upper portion, so that the inner upper portion and the outer upper portion are engaged without a belt when worn. The indoor shoes of the present invention do not fix the instep or the ankle with a belt, but adapt to deformed feet by flexibly adjusting the engaging position of the upper part.

The slippers of the present invention preferably leave the wearer's toe area uncovered when the inner and outer uppers are engaged. Since the toe portion of the indoor shoes is open, it is easy to put on and take off, and it is possible to more flexibly cope with deformed feet.

The indoor shoes of the present invention can be worn according to deformed feet by changing the positions of engagement between the inner upper portion and the outer upper portion. The engaging portion is not particularly limited, and may be a button or string, but 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 shoes of the present invention is lower than the height of the ankle of the wearer's foot, and is such a height that a portion of the calcaneus is exposed from the heel portion. The indoor slippers of the present invention do not fix and support the wearer's ankle, but open the circumference of the wearer's ankle to facilitate walking. The height of the heel is, for example, 5 cm or less, 4 cm or less, 3 cm or less, or 2 cm or less, 1 cm or more, or 2 cm or more, from the midsole. The indoor slippers of the present invention are not only easy to put on and take off by lowering the height of the heel part, but also easy to expand the indoor slippers in the horizontal direction, thereby more flexibly coping with deformed feet. can be done.

A problem caused by reducing the height of the heel is that the heel of the indoor slipper tends to come off the wearer's heel when walking, resulting in unstable walking. The indoor shoe of the present invention solves this problem by providing a counter on each of the inner and outer upper parts. By providing a counter having a length from the vicinity of the heel side end to the vicinity of the bending position of the wearer's foot on each of the inner upper part and the outer upper part, it is possible to match the bending part of the indoor shoes with the bending position of the foot. As a result, even when the foot is bent, the portion provided with the counter follows the foot, and the heel is less likely to come off the foot when the foot is stepped back. Therefore, the indoor shoes of the present invention do not move like slippers or sandals in which the wearer's feet are not accompanied by the movement of the footwear, and stable walking is possible. The length (longitudinal direction) of the counters extending 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, and 16 cm or less, 14 cm or less, or 12 cm or less. is.

The width of the counter near the flexed position of the wearer's foot (length perpendicular to the longitudinal direction of the counter) is preferably wider than the width of the counter near the heel end. For example, the width of the counter near the bending position of the wearer's foot is 1.2 times or more, 1.5 times or more, or 2 times or more and 4 times or less of the width of the counter near the heel side end. , 3 times or less, or 2.5 times or less. By making the width near the bending position of the wearer's foot wider than the width near the heel side end of the counter, the wearer's foot can be more stably supported near the bending position.

The counter is disposed on the surface of the outer fabric or lining fabric of the upper, or between the outer fabric and the lining fabric of the upper. Preferably, the counter is arranged between the front fabric and the back fabric of the upper. 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, stitching, or the like. The slippers of the invention preferably have no counter connected to the insole. If the counter is connected to the insole, it limits the horizontal spread of the slipper and prevents accommodation of deformed feet.

When wearing the indoor shoes of the present invention, the wearer first puts his or her foot on the inner sole of the indoor shoes, then overlaps the inner upper part and the outer upper part so as to wrap around the instep, and engages the inner upper part. and the engaging portion of the outer upper portion. At that time, the engagement position is determined according to the size, deformation, etc. of the foot, and the engagement position is adjusted by the engagement portion. Since the indoor shoes of the present invention have a low heel portion and are worn by winding the inner upper portion and the outer upper portion, it is possible to flexibly adapt to the size and deformation of the foot. Therefore, it is not necessary to insert the foot into the opening when wearing the shoe, unlike indoor shoes with an upper rising from both sides of the midsole and a high heel, and even deformed feet can be easily worn.

Since the indoor shoes of the present invention have a flexible structure that allows size adjustment, they are also suitable for inserting insoles. The insole can be a custom-made insole that fits the wearer's foot, 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 made of different fabrics, or may be made of one piece of fabric. For example, in the indoor shoes of the present invention, an inner sole is attached to a piece of cut fabric, and the portion corresponding to the inner side of the foot across the inner upper 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 portion of the inner upper portion and the heel-side end portion of the outer upper portion can be joined by any means. For example, they may be joined by adhesion, stitching, 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 part and the heel-side end of the outer upper part are joined in advance. It also includes a mode of engaging and joining with a fastener, a line fastener, a button, or the like.

The upper part can be configured by superimposing a front fabric and a back fabric. The structure and material of the upper portion are not particularly limited and may be those commonly used for indoor shoes. Examples include polymer sheets, fabrics made of natural or synthetic fibers, and natural or synthetic leathers. Materials such as natural rubber, 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 to protect the feet. may be used. A mesh fabric may be used for the lining fabric from the viewpoint of improving breathability. Also, both the front fabric and the back fabric may be made of mesh fabric.

The indoor shoes of the present invention preferably have a ground-contacting portion (outsole) on the back portion of the indoor shoes at a position corresponding to the midsole. Abrasion of the indoor slippers can be prevented by providing the contact portion. Since a thick grounding portion may cause overturning, the thickness of the grounding portion is preferably 5 mm or less, or 3 mm or less, and 0.5 mm or more, or 1 mm or more.

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