Description

  TECHNICAL FIELD The present invention relates to a footplate-compatible footwear, and more specifically, to a footplate-compatible footwear that can be used as a normal footwear by an elderly person or a person with a disability when a footplate is not required to be worn.

  The sole plate is like the insole of a shoe used for leg correction.For example, in the case of O leg correction, it is made so that the outside rises a little high, and this is laid in the shoe and worn. The leg is straight without moving the center of gravity outward. There are various therapeutic uses as a treatment tool for ankle joint deformity, for example, a foot with a gentle slope from the outer edge to the inner edge to correct the valgus foot, and the foot faces inward by this inclination There is also a bottom plate (Patent Document 1).

Since the sole plate is thicker than a normal insole, it cannot be attached to all commercially available shoes. Therefore, conventionally, a shoe store with a thick insole has to be searched for in a shoe store, and a user who desires comfort and design has to order a shoe for a sole plate in a custom order.
Therefore, the applicant has proposed shoes that can use a sole plate and can be attached and detached with a hook-and-loop fastener that looks like a lace shoe (Patent Document 2) and a belted shoe that fully opens the front part (Patent Document 3).

  Since the sole plate is not uniform in thickness, when it is attached to a commercially available shoe, the shoe may be displaced in the shoe. If the deviation is large, the effect of the treatment is halved, and in some cases there is even a risk of falling. Therefore, there has been a demand for footwear having a structure that does not cause a shift when the sole plate is mounted.

There is also a need to use it as normal footwear when the sole plate is not worn. Here, since the person who wears the sole plate is often an elderly person or a person with a disability in the foot, it is also necessary to be footwear considering the elderly person. In particular, the conventional foot sole plate-compatible footwear is only for external wear, and there is no indoor footwear corresponding to the sole plate.
It is an object of the present invention to provide a footplate-compatible footwear that can be used as a normal footwear by an elderly person when the footplate is not worn and no slippage occurs in the footwear. .

  Since the outer peripheral shape of the sole plate is unique according to the foot shape of the individual, a special structure for supporting the sole plate is necessary in order to prevent detachment while preventing detachment. Conventionally, leather shoes and the like used a shank to prevent the arch from being deformed or twisted, but were not suitable for footwear for elderly people. In order not to put a burden on the bones of the feet or the MTP joints of elderly people, etc., a sufficient space is required in the toe part, but the sole plate should be supported while providing a sufficient space in the toe part. Was difficult. Therefore, the inventor considered that it is necessary to support the heel with a combination of a core material and a bottom material that supports the heel as a whole in order to prevent the displacement of the sole plate.

That is, the present invention can be freely opened and closed across the opening by means of an upper made of stretchable cloth material, a vertically long and wide opening, and a hook-and-loop fastener provided at one end. The footband-compatible footwear having the adjustment band, the entire inner portion of the heel portion, and the sole material, and using a hard member having rebound resilience to the core portion that entirely covers the heel portion, It is a footstool corresponding footwear characterized by being formed by adhering to an insole material.
In the footwear, preferably, the insole material is composed of a hard material having excellent bending strength from the vicinity of the lateral arch between the MTP joint and the arch to the buttocks, and between the MTP joint and the arch. An inclination that lifts the toe portion upward from the vicinity of the lateral arch to the toe is configured, a portion other than the hard material of the midsole material is configured by a flexible material, and the adjustment band includes the hook-and-loop fastener It consists of a flexible material that has a plurality of parallel sewing lines crossing the length and can be adjusted in length by cutting along the sewing lines, and covering the upper with a certain width at the boundary area with the bottom member. And a thick cup insole that is detachable.

According to the present invention, it is possible to prevent the sole plate from being displaced by the insole material and the counter, and as a result, the feet can be firmly fixed, thereby enabling stable walking.
Moreover, when not wearing a sole board, the footwear which an elderly person etc. can use on a daily basis can be provided.

The best mode for carrying out the present invention will be described with reference to FIGS.
The upper 1 is made of a lightweight and stretchable cloth material. For example, polyester is disclosed, but the invention is not limited thereto. The boundary region between the upper 1 and the bottom member 3 is preferably configured so as to cover the outer periphery of the bottom member 3 with an edge rising 13 extending from the bottom member 3. With this configuration, even if the sole plate is wider than the shape of the bottom material of the footwear, the cloth material covering the upper 1 extends to expand the width of the upper or the tip of the upper and is supported by the edge rising 13. Is acceptable. The edge rise 13 may be designed with a wavy line or the like, or the rise width may be adjusted to improve the design.
The shape of the toe has a height that does not hit the first and fifth heels, there is a toe clearance (discarded dimension), there is a length that does not compress the toes, and there is a width that the MTP joint is not compressed. It is important (see Fig. 8). Further, it is preferable that the toe box has a sufficient height so as to cope with the deformation of the foot.

  The opening 2 is vertically long and wide so that elderly people can easily take in and out their feet, and preferably has a length exceeding half of the upper (bottom member). An adjustment band 7 is provided to prevent the footwear from falling off due to the wide opening. One end of the adjustment band 7 is sewn, and the tightening degree can be arbitrarily adjusted by a hook-and-loop fastener 8 provided on the back side of the other end. The hook-and-loop fastener 8 is configured to be relatively long in the longitudinal direction of the adjustment band 7, and a plurality of parallel sewing lines that cross the hook-and-loop fastener are provided, and the length can be adjusted by cutting with the scissors along the sewing line. It is preferable to do so.

  The bottom member 3 is made of a lightweight and flexible material mainly made of synthetic leather. For example, synthetic leather made of 60% nylon and 40% polyurethane is disclosed, but not limited thereto. A flat bottom without a heel is exemplified as a general shape, but irregularities may be provided in accordance with individual physical characteristics. Moreover, it is preferable to provide an appropriate anti-slip | skid as needed.

A counter 15, which is a core material for wrapping the heel and holding it as a whole, is fixed to the heel portion 9 and fixed to the rear middle bottom material 6. By configuring the counter 15 and the rear midsole member 6 with hard members, it is possible to suppress the displacement of the sole plate and to prevent the footwear from being twisted.
By the way, when an elderly person or the like wears footwear whose bottom portion is excellent in flexibility, the outside of the shoe may sink due to its own weight and the foot may be varnished. In the footwear of the present invention, the counter 15 properly receives its own weight, and the valgus is prevented by firmly supporting the sole plate by the reaction force.
As described above, the core material constituting the counter 15 needs to be made of a material that does not lose its shape, and the material is not particularly limited as long as it is a hard member having rebound resilience. . Adhesion between the counter 15 and the rear midsole member 6 needs to maintain sufficient strength. For example, bonding with an adhesive is disclosed.
The upper part of the heel part 9 is provided with a loop 4 into which fingers of the hand are sufficiently inserted. When worn, the elderly person or a disabled person can easily insert the finger of the hand and lift the heel part of the footwear. Making it easy.

Examples of the material of the rear inner bottom material 6 include, but are not limited to, a hard non-woven cloth made of polyester fibers. By making the material of the front midsole material 5 from a flexible material, it is possible to cope with the natural deformation of the bottom member fitted to the dynamic change of the foot during walking.
Although the midsole members 5 and 6 may be made of the same material, it is necessary to ensure the strength that the midsole members 5 and 6 can support the feet integrally with the counter 15 in that case. Prototypes made of the same material for the midsole materials 5 and 6 could be constructed with a synthetic material of approximately 1 mm in thickness, and a urethane material of approximately 2 mm in thickness, combining Texon (registered trademark) fibers and cardboard. .

  Since the midsole members 5 and 6 are hard and uncomfortable to wear, a cup insole 10 as shown in FIGS. A convex portion 14 is provided on the surface of the cup insole 10, and the lateral arch of the metatarsal bone is naturally pressed. Shock absorbers 11 and 12 are provided on the back surface, so that the impact applied to the foot during walking is absorbed and the fatigue of the pedestrian is alleviated. The comfort may be improved by providing a cushion material having a predetermined thickness on the upper surfaces of the midsole members 5 and 6 without providing the cup insole. In this case, it can also be worn without wearing the sole plate.

  The toe spring 17 is an inclination of a sole plate constituted by the hard front midsole member 5, and thereby the toe portion of the wearer is lifted upward. As shown in FIG. 8, there is a side arch between the MTP joint (base joint) and the arch, and the side arch absorbs the impact when the foot reaches the ground and plays a role of a spring during walking. . It is said that when the lateral arch collapses, the metatarsal bones spread and become an open leg, and the toe spring 17 is configured to have an inclination enough to lift the lateral arch. Preferably, the starting point of the toe spring 17 is configured to be slightly behind (heel side) from the lateral arch (see FIGS. 2 and 3), and has a height of approximately 1 to 4 cm (preferably approximately 3 cm). Since the toe portion is lifted by providing the inclination in this manner, it is possible to prevent the stutter due to the step.

  The footwear of the present invention is suitable for elderly people and disabled people, but provides footwear for all plantar plate users regardless of age or gender. Especially for indoor wear, almost all parts tend to be composed of flexible materials in order to pursue comfort, but by constructing the counter that supports the buttocks and the insole with hard materials, It provides new indoor footwear with a soft feeling while responding.
