Description

The present invention relates to short shoes that can be taken off without bending down, for example.

Nowadays, there are various variations of shoes such as short shoes, including not only shoes that emphasize functionality and shoes that emphasize design, but also shoes that emphasize both functionality and design.

By the way, when taking off the left and right shoes, it is common to take them off while supporting the shoes with your hands, but in the case of people who have difficulty bending over, such as pregnant women or elderly people, for example, if you are a pregnant woman or elderly person who has difficulty bending down, you can place the rear foot of one shoe on top of the other. Sometimes I take it off while holding it in place.

Therefore, various types of shoes have been proposed that make it easier to take them off. For example, Patent Document 1 proposes a shoe in which a protrusion for hooking the other shoe is provided on the rear surface of the hindfoot.
In Patent Document 1, it is said that by stepping on the protrusion of one shoe and hooking the other shoe, one shoe can be held down by the other shoe, allowing the user to take off the shoe without bending over.

However, in the shoes of Patent Document 1, when taking off one shoe, the other shoe is hooked on the protrusion as if stepping on the protrusion, so a downward load is likely to be applied to the upper surface of the protrusion. For this reason, in Patent Document 1, there was a risk that the rear foot part would be damaged due to the downward load applied to the upper surface of the protrusion.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide short shoes that prevent damage to the hindfoot and that can be taken off without bending over.

The present invention provides a pair of short shoes comprising an upper that covers the instep side of the foot and a sole that covers the back side of the foot, the sole of the shoe causing friction on a part of the rear foot compared to the surrounding area. A rear anti-slip part is formed of a material with a large coefficient, and the rear anti-slip part forms the anti-slip surface which becomes the bottom surface of the sole and a part of the inner surface of the rear foot part, and the other short shoe forms a side surface of the sole. It is characterized by having an abutment surface that is pressed from both sides.

The hindfoot refers to the part of the sole of the foot that is closer to the heel than the part corresponding to the arch of the foot.
The above-mentioned material having a large coefficient of friction refers to, for example, a rubber material used as a non-slip material.
The inner surface of the hindfoot refers to the surface that intersects with the bottom surface of the sole and faces the other shoe.

According to this invention, the other short shoe is pressed against the abutment surface of the rear anti-slip part formed of a material with a larger coefficient of friction than the surrounding area, so that the abutment surface functions as a non-slip part for the other short shoe. be able to.
As a result, one of the short shoes is held down by the frictional resistance of the contact surface, making it easier to pull out the foot from the shoe opening.

Furthermore, because one short shoe can be held down without stepping on the other short shoe, damage to the hindfoot can be prevented compared to, for example, when the other short shoe is hooked onto a protrusion provided on the hindfoot. can.
Therefore, the short shoes can prevent damage to the hindfoot and can be taken off without bending over.

In addition, the rear anti-slip part is equipped with an anti-slip surface that functions as a non-slip part against the road surface and a contact surface that functions as an anti-slip part for the other short shoe, so that the short shoe does not come into contact with the part that has the anti-slip surface. Deterioration in moldability can be suppressed compared to the case where the portion having a surface is constructed separately.

As an aspect of the present invention, the contact surface may be formed from an inner surface of the hindfoot to a rear surface of the hindfoot.
According to this configuration, it is possible to secure a large area in the rear foot portion of the shoe sole against which the other short shoe can be pressed. Therefore, the short shoes can be adapted to various people who press the short shoes in different ways, and the usability can be improved.

Further, as an aspect of the present invention, the abutment surface may be formed to be substantially flush with the inner surface around the abutment surface.
According to this configuration, the abutment surface of the rear anti-slip portion does not protrude from the inner surface around the abutment surface.

As a result, the contact surface of the rear anti-slip portion can be prevented from being stepped on by the other short shoe, so that the short shoe can reliably prevent damage to the rear foot portion due to a downward load.
Furthermore, since deterioration in appearance due to protrusion of the contact surface can be suppressed, it can be easily applied to shoes where design is important.

Moreover, as an aspect of the present invention, a plurality of narrow groove-like grooves may be provided on the contact surface.
According to this configuration, when a downward load is applied to the contact surface, the rear anti-slip portion can be appropriately bent. As a result, downward loads can be appropriately absorbed, and the short shoes can prevent damage to the contact surfaces due to excessive downward loads.

Further, as an aspect of the present invention, the rear anti-slip portion may be formed of a rubber material, and the other portions of the sole may be formed of ethylene vinyl acetate.
According to this configuration, the weight of the sole can be reduced compared to a case where the entire sole is made of a rubber material.

Further, as an aspect of the present invention, the sole may include a portion of the forefoot portion made of a material having a larger coefficient of friction than the surrounding area, and may include a front anti-slip portion forming the bottom surface of the sole.
The forefoot section refers to the part of the sole of the foot that is closer to the toe than the part that corresponds to the arch of the foot.

According to this configuration, the rear anti-slip portion and the front anti-slip portion cooperate to improve the anti-slip performance on the road surface.
This prevents one shoe from slipping when you pull your foot out of the collar while holding the other shoe in place, making it easier to pull your foot out of the collar. can do.

This sole 3 is constructed by molding a sole main body 31 by, for example, injection molding onto a front anti-slip part 32 and a rear anti-slip part 33 that have been formed in advance.
Here, the part of the sole 3 corresponding to the arch of the sole of the foot is referred to as the midfoot part 3a, the part closer to the toe than the midfoot part 3a is the forefoot part 3b, and the part closer to the heel than the midfoot part 3a is the rear part. The sole 3 will be further explained as the foot portion 3c.

Specifically, the sole body 31 is made of relatively lightweight ethylene vinyl acetate, and constitutes the forefoot portion 3b, midfoot portion 3a, and rearfoot portion 3c of the sole 3. A groove (not shown) is provided on the bottom surface of the sole body 31 to prevent a water film from forming between the sole body 31 and the road surface.

Further, as shown in FIGS. 2(b) and 3(b), the front anti-slip portion 32 has a generally rectangular shape in bottom view that is short in the front-rear direction, and is embedded in the sole body 31 in the forefoot portion 3b of the sole 3. At the same time, the sole body 31 constitutes the bottom surface of the sole 3.

This front anti-slip part 32 is made of a rubber material with a higher coefficient of friction than the sole body 31 so as to function as a non-slip part against the road surface, and has a groove (number omitted) with a pattern different from that of the sole body 31 on the bottom surface. is provided.

Further, as shown in FIGS. 2(b) and 3(b), the rear anti-slip portion 33 is embedded in the sole body 31 in the rear foot portion 3c of the sole 3, and the anti-slip surface 33a, which is the bottom surface, is embedded in the sole body 31. The sole body 31 constitutes the bottom surface of the sole 3.

This rear anti-slip part 33 is made of a rubber material having a higher coefficient of friction than the sole body 31 so as to function as a non-slip part on the road surface, and has a groove (symbol: (omitted) is provided.
Note that the rear anti-slip portion 33 is made of the same rubber material as the front anti-slip portion 32.

More specifically, as shown in FIGS. 2(b) and 3(b), the rear anti-slip portion 33 has a thickness thinner than the sole body 31 and has a curved surface protruding rearward when viewed from the bottom. It is formed into a kamaboko shape.

Further, as shown in FIGS. 1 to 3, the rear anti-slip portion 33 is designed so that the surface in the range from the inner surface to the rear surface is exposed in the range from the inner surface to approximately the center of the rear surface of the sole 3. It is buried in the inner side of the rear leg portion 3c of the sole 3.
A surface in the range from the inner surface to the rear surface of the rear anti-slip portion 33 is formed as a contact surface 33b against which the other short shoe 1 is pressed from the side when one shoe 1 is taken off.

Therefore, the contact surface 33b of the rear anti-slip portion 33 constitutes a part of the inner surface and a part of the rear surface of the sole 3, as shown in FIGS. 2(b) and 3(b). It is formed substantially flush with the inner and rear surfaces of the sole body 31.
The contact surface 33b of the rear anti-slip portion 33 is provided with a plurality of narrow groove portions 33c extending from the inner surface to the rear surface of the sole 3 at predetermined intervals in the vertical direction.

Next, the states of the right shoe 1R and the left shoe 1L when the right shoe 1R is taken off, for example, in the shoe 1 having the above-described configuration will be explained using FIGS. 4 and 5.
For example, when taking off the right shoe 1R's rear foot 3c (see Figure 2) by holding it with the left shoe 1L's rear foot 3c (see Figure 3), as shown in Figure 4, the contact surface 33b of the right shoe 1R The contact surface 33b of the left shoe 1L is pressed against the right shoe 1R.
For example, when taking off the right shoe 1R by holding the rear foot 3c with the middle foot 3a (see FIG. 3) of the left shoe 1L, as shown in FIG. 5(a), the contact surface 33b of the right shoe 1R The middle foot 3a of the left shoe 1L is pressed against the right shoe 1R.

For example, when taking off the right shoe 1R by holding the rear foot 3c with the forefoot 3b (see FIG. 3) of the left shoe 1L, the left The forefoot portion 3b of the shoe 1L is pressed against the right shoe 1R.

In any of the above-mentioned conditions, the contact surface 33b of the rear anti-slip portion 33 of one pair of short shoes 1 functions as an anti-slip for at least the other short shoe 1, so that one pair of short shoes 1 can prevent the foot from slipping from the opening 2a. can be easily pulled out.

As described above, a pair of short shoes 1 according to the first embodiment includes an upper 2 that covers the instep side of the foot, and a sole 3 that covers the back side of the foot.
The sole 3 of these short shoes 1 includes a rear anti-slip section 33 formed of a rubber material having a larger coefficient of friction than the sole body 31 on a part of the rear foot section 3c. The shoes are provided with a slip-resistant bottom surface 33a that becomes the bottom surface of the shoe, and an abutment surface 33b that becomes a part of the inner surface of the rear foot portion 3c and against which the other short shoe 1 is pressed from the side.

According to this configuration, the other short shoe 1 is pressed against the contact surface 33b of the rear anti-slip portion 33, which is formed of a rubber material with a larger coefficient of friction than the sole body 31, so that the contact surface 33b is It can be made to function as a non-slip part for 1.
As a result, one of the short shoes 1 is held down by the frictional resistance of the contact surface 33b, making it easier to pull out the foot from the opening 2a.

Furthermore, since the short shoes 1 can be held down without stepping on one short shoe 1 with the other short shoe 1, the hindfoot portion 3c is more stable than when the other short shoe 1 is hooked onto a protrusion provided on the hindfoot portion 3c, for example. Damage can be prevented.
Therefore, the short shoes 1 can prevent damage to the rear foot portion 3c and can be taken off without bending down.

In addition, since the rear anti-slip portion 33 includes an anti-slip surface 33a that functions as a non-slip portion against the road surface and an abutment surface 33b that functions as an anti-slip portion for the other short shoe 1, the short shoe 1 Compared to the case where the portion having the contact surface 33b and the portion having the contact surface 33b are constructed as separate bodies, deterioration in moldability can be suppressed.

Further, since the contact surface 33b is formed from the inner surface of the rear foot portion 3c to the rear surface of the rear foot portion 3c, the short shoe 1 can press the other short shoe 1 against the rear foot portion 3c of the sole 3. A wide range can be secured. Therefore, the short shoes 1 can be adapted to various people who press the short shoes 1 in different ways, and the ease of use can be improved.

Furthermore, since the abutment surface 33b is formed to be substantially flush with the inner surface of the sole body 31, the abutment surface 33b of the rear anti-slip portion 33 does not protrude from the inner surface of the sole body 31. There is no.
As a result, the contact surface 33b of the rear anti-slip portion 33 can be prevented from being stepped on by the other shoe 1, so the shoe 1 can reliably prevent the rear foot portion 3c from being damaged by a downward load.
Furthermore, since deterioration in appearance due to the protrusion of the contact surface 33b can be suppressed, it can be easily applied to shoes where design is important.

In addition, since the contact surface 33b is provided with a plurality of narrow grooves 33c, the shoe 1 can appropriately deflect the rear anti-slip portion 33 when a downward load is applied to the contact surface 33b. . Thereby, the downward load can be absorbed appropriately, so that the shoe 1 can prevent damage to the contact surface 33b due to excessive downward load.

In addition, since the rear anti-slip portion 33 is made of a rubber material and the sole body 31 is made of ethylene vinyl acetate, the shoe sole 3 of the short shoes 1 has a lower sole 3 than a case where the entire sole 3 is made of a rubber material. Weight reduction can be achieved.

In addition, since the sole 3 is formed of a rubber material having a larger coefficient of friction than the sole body 31 in a part of the forefoot portion 3b, and is provided with a front anti-slip portion 32 forming the bottom surface of the sole 3, the short shoes 1 By the cooperation of the rear anti-slip part 33 and the front anti-slip part 32, it is possible to improve the anti-slip performance on the road surface.

As a result, when one short shoe 1 is held by the other short shoe 1 and the foot is pulled out from the opening 2a, one of the short shoes 1 can be prevented from slipping. can be pulled out more easily.
