Description

The present invention relates to sandals used at home, workplaces, hospitals, nursing care facilities, etc., and particularly to sandals that can be put on and taken off from both the front and back directions.

Sandals are widely used as simple footwear at home or in hospitals. When putting on the same footwear after taking it off, the footwear must be turned in the correct direction before being put on. At home, people often put on and take off footwear while holding things in both hands, and in hospitals, they are often used by patients with physical disabilities. However, it is troublesome and requires a lot of effort for a patient to bend down and change the direction of the footwear while carrying luggage in both hands or for a patient with limited mobility. Furthermore, when changing the orientation of footwear when using the toilet, etc., it is unsanitary to operate the footwear by hand.
As a method to solve the above-mentioned problem, many proposals have been made for sandals that can be put on and taken off in both directions without requiring an action to change the orientation. Conventional shapes include a belt section for passing the feet approximately in the center of the sandal platform on which the feet are placed, as well as a shape in which the belt section is placed over the sandal platform in the longitudinal direction as shown in Patent Document 1 or Patent Document 2 below. In other words, it has been proposed to be movable in the front-back direction, with the belt portion positioned in front of the foot placed on the sandal stand.
The configuration described in Patent Document 1 is a sandal that includes a sandal base on which the foot is placed, and a belt portion provided in an arch shape on the upper part of the sandal base and secured to the foot. A pair of left and right guide rail parts are formed along the length and approximately at the center in the longitudinal direction, and guide rollers are provided at both left and right ends of the belt part, and the left and right guide rollers of the belt part are attached to the left and right guide rail parts, respectively. The belt portion can be slid in the longitudinal direction of the sandal base by fitting in a slidable manner.
The configuration described in Patent Document 2 includes metal or hard plastic rings provided at four locations in total, two on each side of the belt portion that is secured to the foot, and one ring on each side in the longitudinal direction of the sandal base. By providing a pipe and passing a ring of the belt section through this pipe, the belt section can be moved back and forth along the pipe.
The structure of the sandal described in Patent Document 3 is a sandal in which a belt portion is slidable in the front-rear direction relative to a sandal base, and the sandal base includes an overlay portion that is a foot resting portion and an underlay portion whose entire surface is a ground contact portion. and an insole part located between the overlay part and the underlay part, the insole part consisting of a first part, a second part, and a slide receiving plate having a slide groove approximately in the center, The first part and the second part are adhered to the upper surface of the underlay with the slide receiving plate sandwiched in the center, and have a sliding part that slides back and forth in the guide groove, and the belt part The left and right end portions of the slide portion are fixed to the left and right side portions of the slide portion, respectively.
The belt part of conventional sandals is fixed at two points on the left and right sides of the sliding part of the sandal, so the length is determined from the average foot size and the length is always uniform. Another problem is that it is uncomfortable for users with large feet or small feet, and is extremely dangerous when walking.
Furthermore, since the belt part is fixed to the slide part with two-point support, the belt part can be moved back and forth within the range of the slide part, but the heights of the toe side and the instep side are different, so The instep side and the belt part touch, and the belt part remains at a constant horizontal height and slides as it is, but since the belt part does not tilt, the belt part is lower on the toe side of the foot, while the foot remains floating. The problem is that only the instep side of the foot is touching, and it doesn't fit the top of the foot.
The sandals of the present invention solve these problems by making it possible to adjust the length of the arch-shaped belt part, and by making the belt part supported at one point so that it can rotate within a certain range in the front and back direction. When a user puts on sandals, by inserting the foot, the length can be adjusted by attaching and detaching hook-and-loop tape, such as Velcro (registered trademark) tape, and by opening and closing the hook button. , the belt part tilts forward and stops rotating on the toe side, creating a state where it fits the top of the foot. Able to walk stably.

Utility model registration No. 3135517 Utility model registration No. 3026587 Patent No. 5686973 (see claims section, detailed description of the invention section, and FIGS. 1 to 3)

In each of the configurations described in the above-mentioned prior art documents, the left and right sides of the belt portion are slidably attached in the longitudinal direction of the sandal base, thereby making the belt portion movable in the front-rear direction of the sandal base. Since the belt portion corresponds to the instep of the foot, it is made of a flexible material such as cloth or leather. In addition, a configuration in which a guide roller provided at the end of the belt portion is moved within a guide rail provided on a sandal stand as shown in Patent Document 1, or a structure in which a ring provided in the end portion of the belt portion as shown in Patent Document 2 is moved between the sandals In a configuration in which the ring is moved through a pipe provided on a stand, a gap exists between the guide roller and the guide rail or between the ring and the pipe. As a result, when walking, the positions of the left and right guide rollers or rings are largely misaligned, causing distortion of the belt portion, causing discomfort to the user and making it difficult to walk.
Furthermore, although the belt part can be slid left and right in the longitudinal direction, the belt part cannot fit the size of the user's feet. This is extremely dangerous and problematic as both of them end up walking in an unstable state.
Furthermore, since the belt section is fixed, the height is different (slanted) from the user's toes to the instep, so the belt hits the belt section in a line at the highest point of the instep. In that state, it slides left and right while remaining horizontal. In this case, the instep of the foot cannot rotate (arc movement) according to the slope of the instep, so the instep of the foot slides in a linear manner, making it unstable and extremely dangerous for walking. That's a problem.
The present invention solves the above-mentioned problems, and provides footwear such as sandals that can be put on and taken off from both the front and back directions, in which the size of the belt part can be adjusted, and the belt part is supported at one point so that it can be tilted freely. The length of the belt part can be adjusted to accommodate the size of the foot, and since the belt part is tiltable, it can be adapted to almost any special shape from the top of the foot to the tip of the foot. To provide sandals which are conveniently supported by a surface and at the same time enable safe walking.

A first aspect of the present invention that can achieve the above object is a sandal as described in claim 1, which is as follows.
A sandal in which a belt portion is slidable in the front-rear direction with respect to a sandal base, and the sandal base is located between an overlay that is a footrest, an underlay whose entire surface is a ground contact portion, and the overlay and the underlay. an insole, the insole is formed by a first part and a second part of the insole, and a slide receiver is divided into an upper part and a lower part so as to have a slide groove between the first part and the second part of the insole. The first and second parts of the insole are glued to the upper surface of the underlay with the slide receiving member sandwiched in the center, and the slide receiving member is a slide receiving member divided into an upper part and a lower part. A slide portion bent into a substantially concave shape is provided so as to slide back and forth in the slide groove of the member, and one of each of the two divided belt portions is supported at one point at both raised ends of the substantially concave shape of the slide portion. It is configured to be rotatably attached, and the length of the belt can be adjusted by pulling the two belt parts together and fixing them in a detachable manner.

A second aspect of the present invention that can achieve the above object is a sandal as described in claim 2, which is as follows.
In place of the structure in which a belt section is directly divided into two parts on both ends of the sliding part which is bent into a substantially concave shape and raised up, both ends of the sliding part which is bent into a substantially concave shape and raised up are provided. The overlapping part of one belt part is widened with a margin, and the belt part and the intermediate support member are pulled together and fixed removably, and the length of the belt part is adjusted using an intermediate support member supported at one point. This configuration allows for adjustment of the height.

Since the sandals according to the present invention have the configuration as described above, they exhibit the effects described below.
(1) Since the length of the belt part can be adjusted, it provides stable comfort regardless of the size of the foot.
(2) Since the belt part is supported at one point and can be tilted freely, when wearing the sandals of the present invention, the belt part of the sandal and the foot are in surface contact rather than a line contact, resulting in stable wearing comfort. be.

A sandal in which a belt portion is slidable in the front-rear direction with respect to a sandal base, and the sandal base is located between an overlay that is a footrest, an underlay whose entire surface is a ground contact portion, and the overlay and the underlay. an insole, the insole is formed by a first part and a second part of the insole, and a slide receiver is divided into an upper part and a lower part so as to have a slide groove between the first part and the second part of the insole. The first and second parts of the insole are glued to the upper surface of the underlay with the slide receiving member sandwiched in the center, and the slide receiving member is a slide receiving member divided into an upper part and a lower part. A slide portion bent into a substantially concave shape is provided so as to slide back and forth in the slide groove of the member, and one of each of the two divided belt portions is supported at one point at both raised ends of the substantially concave shape of the slide portion. These sandals are rotatably attached, and the length of the belt parts can be adjusted by pulling the two belt parts together and fixing them in a removable manner.

Sandals according to a first embodiment and a second embodiment of the present invention will be described below based on the drawings shown in FIGS. 1 to 4.
The present invention allows sandals to be put on and taken off from both the front and rear directions, the length of the belt part to be freely adjustable, and both ends of the belt part to be tiltable by being supported at one point.

First, the overall image of the sandal according to the first embodiment of the present invention will be explained based on FIG. 1(b).
The elements constituting the first embodiment include a sandal sole 1, an insole 2 consisting of two parts, front and back, a slide receiving member 3 divided into upper and lower parts, a slide part 4, an overlay 6, and a belt part 7. .
The underlay 1 constitutes the lowest layer of the sandal, and is made of synthetic resin such as polyurethane and has a non-slip surface on its lower surface.
The insole 2 consists of two parts, a first insole part 8 and a second insole part 9, and is made of synthetic resin such as polyurethane. The first part 8 of the insole and the second part 9 of the insole are adhered to the upper surface of the insole 1 with the slide receiving member 3 sandwiched approximately in the center.
The slide receiving member 3 is made of metal or hard synthetic resin, has protrusions formed at both ends in the front and back direction, and has an upper part 31 and a lower part 32 overlapped so that a slide groove 10 for sliding the slide part 4 is provided. It forms the slide portion 4.
When the slide receiving member 3, which is assembled from the upper and lower parts 31 and 32, is sandwiched between the first insole member 8 and the second insole member 9 and adhered to the upper surface of the insole 1, a slide groove is formed approximately in the center. 10 is formed.

The slide portion 4 is made by bending metal to form a substantially concave shape or by molding a hard synthetic resin.
One hole for a pin that rotatably supports the belt portion 7 is formed at the upper end of the approximately concave-shaped double-folded portion, approximately in the center, and the belt portion 7 is divided into two parts, each of which can be rotated as described above. By means of fasteners 11 such as pins, which are freely supported, the substantially concave-shaped holes at both bent ends and the respective ends of the belt section 7, which is divided into two parts, are rotatably supported.

Since the slide receiving member 3 is divided into an upper part and a lower part 31, 32, the slide part 4 is placed on the lower part 32 of the slide receiving member 3, and the upper part 31 of the slide receiving member 3 is placed on top of the slide part 4 to sandwich it. It is something.
Moreover, when the slide part 4 is placed on the slide receiving member 3 and is slid, it is configured to slide on the upper surface of the lower part 32 of the slide receiving member 3.
As described above, the belt part 7 is divided into two parts by a hole for a pin drilled approximately at the center of the upper part of the double-folded part of the slide part 4 which is bent into a substantially concave shape. The ends of each longitudinal direction are rotatably supported by fasteners 11 such as pins.

The belt portion 7 described above has the following configuration.
The belt part 7 functions as the instep pad 12, and is a part that holds the instep of the user's foot, and is made of a flexible material such as woven fabric, leather, or synthetic resin.
If the structure of the belt part 7 divided into two parts is one undivided belt part 7, the size of each user's feet will be different, so there will be cases where the shoes do not fit comfortably. .
This can be done by dividing the belt part 7 into two and providing a removable belt part 7 using hook-and-loop tape, for example, Velcro (registered trademark) tape, so that the length can be adjusted. In the sandals of the second embodiment, a plurality of rows of hook buttons 13 are provided in the longitudinal direction, and a plurality of male and female hook buttons 13 are provided in the width direction, so that the sandals can be attached and detached to adjust the length. It is something.
Furthermore, since the sandals can be put on and taken off from both the front and back directions, the belt portion 7 is the part that holds the top of the foot when the shoes are worn from the front and the back. At this time, the height of the instep and the tip of the foot are different. If the belt part 7 does not rotate, the belt part 7 will touch the instep of the foot, and even if you try to put it on firmly, the belt part 7 will slide within the sliding range, but the part where the belt part 7 and the instep of the foot make contact will line up. If they touch each other, the fit will not be comfortable. By making the belt part 7 freely rotatable, the belt part 7 can rotate in the direction of the lower toe of the foot from the state where it is stopped within the sliding range, and the belt part 7 will be in a tilted state, which improves the comfort of wearing. It's good and fits your feet well.

FIG. 2(a) is a three-dimensional perspective view of the completed sandal of the second embodiment, and FIG. 2(b) is a three-dimensional perspective view of the completed sandal of the first embodiment.
The lowest layer of the sandal body is an underliner 1, on which a first part 8 of the insole and a second part 9 of the insole are bonded so that the lower part 32 of the slide receiving member 3 is sandwiched therebetween.
An upper part 31 of the slide receiving member 3 is provided to face the lower part 32 of the slide receiving member 3. Since the height of the upper and lower parts 31 and 32 of this slide receiving member 3 is made to be the same as the height of the insole 2, the slide receiving member consists of the first part 8 of the insole, the upper part 31, and the lower part 32. 3. The insole 6 is adhered to the second part 9 of the insole, and the sandals are integrated.
It goes without saying that the slide part 4 should be set before the upper part 31 and lower part 32 of the slide receiving member 3 are overlapped.
With the above configuration, the belt part 7 slides back and forth on the sandal main body together with the slide part 4 that slides back and forth on the lower part 32 of the slide receiving member 3, and at the same time, the belt part 7 slides back and forth on the sandal body, and at the same time, the belt part 7 slides back and forth on the sandal body. When the tip of the sandal is inserted into the sandal, and when the sandal is finished, the belt part 7 that touches the instep of the foot is rotatably attached with one point support, so it tilts and becomes comfortable to wear.
The belt section 7 attached to the substantially concave-shaped slide section 4 was pushed by the instep of the foot and moved to the left, and the lateral end 41 of the slide section 4 came into contact with the end of the slide receiving member 3. Stop at a position.
At this time, as described above, since the belt part 7 is rotatably provided on the slide part 4 with one point support, it tilts and fits the foot, so that stable walking is possible.

The two embodiments of the belt portion 7 of the embodiment and the common members have been described above.As a second embodiment, as shown in FIGS. It is formed by bending the slide receiving member 3 into a concave shape, and an intermediate support part 14 is provided with a pin or the like to be rotatably supported at one point at the upper part of both rising parts. The intermediate support portion 14 is made of the same material as the belt portion 7, and is provided with multiple rows of hook-and-loop tape, such as Velcro (registered trademark) tape, or a hook button so that the length of the belt portion 7 can be adjusted. In response to this, hook-and-loop tape, such as Velcro (registered trademark) tape or hook buttons, are provided at both ends of one belt section 7 to connect both rising sections, so that the belt can be freely attached to the user's feet. The length can be adjusted by pulling them together.
With this configuration, the same functions and effects as in the first embodiment can be achieved.
In addition, as drawings to supplement the above explanation, FIGS. 3(a) and 3(b) show vertical cross-sections at the center of the sandals of the first and second embodiments, to help understand the configuration more specifically. Make it clear that you can.
In addition, the part where the arch of the foot is placed on the sandal overlay 6 should be formed with a raised part that roughly matches the shape of the arch, and the belt part or the entire surface of the sandal should be coated with fluorescent paint or a fluorescent film. It is also possible to make it easier to see even in dark places by pasting it.

Footwear has a variety of uses, not just sandals, but sandals in particular can be worn both indoors and outdoors.
