  However, in the conventional shoes, there is a problem that the return of the flexible member disposed in the heel portion is poor and the heel does not restore well even though the shoes have been worn. Moreover, in the thing which distribute | arranged the separate member to the collar, there existed a problem that there was a foreign body feeling in the collar part by all means, and a feeling of wearing was not good. Furthermore, in the case where the hole is opened, the heel is exposed to the outside, and it is closer to the sandal rather than the shoe, and there is a problem that the supportability of the foot is not good.

  On the other hand, those provided with fasteners do not have the above-mentioned problems, but the fastener operation is essential and it is difficult to use for the elderly with handicapped people. In addition, the fastener itself is also fragile, and there is also a problem that the damage to the fastener makes it necessary to discard the shoe although there is no problem with the shoe itself.

  An object of the present invention is to provide a shoe that has a good return of the heel part after being worn, is easy to be worn even by elderly people and the like, and can be worn without feeling of foreign matter.

The shoe of the present invention is a shoe in which a bending member formed separately from the heel portion is formed of an elastic material inside the heel portion and has different elastic portions in the upper and lower sides, and the bending member the rear side is curved arcuately in a manner which is convex in the width direction, the vertical direction, and a small bent portion elastic modulus formed on the upper side, and a large base of elastic modulus which is formed on the lower side, the lower end A tongue portion formed on the base portion and extending from the base portion toward the toe side, and the tongue portion has a distal end side so that the insole of the shoe and the inner surface of the bending member are smoothly connected to each other. When the shoe user puts his / her foot into the mouth of the shoe and presses the heel portion with the foot, only the bent portion side of the bending member is supported by the base portion while being inward. bending, before the foot after the fall the inner shoe, the bent portion side to resiliently return to its original state, curved Flexure member is characterized in that fits inside of the heel portion.

  According to the present invention, when the user steps on the upper part of the buttocks and puts the foot in the footwear, the upper part of the buttocks is compressed by the user's eyelid and is bent inward. At this time, the bending member disposed inside the buttocks is also compressed, and the base side is not bent due to the difference in the elasticity of the bending member, and the state as it is is held, and the bending portion side is bent inward Be When the foot fits in the shoe, the bending portion which has been bent inward returns to its original state by its own elastic force, and the buttocks are restored to their original shape. This allows the user to wear shoes without particularly using shoehorns and the like.

In the shoe, the bending member may be curved so that the upper surface portion of the upper end of the bending member and the front side end portion of the tongue portion are arranged on the same perpendicular line. Further, the base side of the bending member is formed to be thicker and wider than the bending portion side, and the thickness increases toward the bending portion side of the bending member. Formed to be thin and narrow in width, and further, the bending member is curved in a bow shape with a convex rear side, the center is thickest and the thickness decreases toward both sides in the width direction It is good. In addition, the portion above 1/3 below the bending member may be the bending portion.

  In addition, a support member may be disposed on the rear side of the base in such a manner as to partially replace the rear part of the base, and the support member is made of a material such as synthetic resin having a smaller specific gravity than the bending member. You may form.

  Further, when the shoe is a leather shoe, the bending member is fixed to a section formed by cutting off the upper part of the buttock of the leather shoe, and the bending member is disposed in the original position while the section is placed in the original position. It may be fixed to the inside of the buttocks.

  In addition, the bending member may be formed of any of synthetic rubber, natural rubber, and synthetic resin.

  According to the present invention, in the shoe in which the bending member formed of an elastic material is disposed inside the buttocks, the bending member is provided with regions having different elasticity in the upper and lower sides, and the bending is small at the upper side. When the shoe user puts his / her foot on the lower side, the bent part is bent inward while being supported by the base, and after the foot is inside the shoe, the bent part is elastic Since the original state is restored, the user can wear shoes without using a shoehorn or the like. Therefore, unlike conventional shoes, it is possible to provide an easy-to-wear shoe that can be easily worn even by elderly people and the like without the problem that the flexible member disposed on the heel portion does not return properly.

Embodiment 1
Hereinafter, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is an explanatory view showing a configuration of a shoe 1 for an elderly person according to a first embodiment of the present invention. 2-4 is explanatory drawing which shows the structure of the bending member 6, FIG. 2 is a perspective view of the bending member 6, FIG. 3 (a) is a front view, (b) is a top view, (c) ) Is a side view, FIG. 4A is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 4B is a cross-sectional view taken along the line BB. As shown in FIGS. 2 to 4, the bending member 6 is formed so that the width W and the thickness t become smaller toward the upper side, and a base portion 11 disposed on the shoe sole portion 5 side, and an upper portion of the base portion 11. It is comprised from the bending part 12. FIG. The bent portion 12 is formed integrally with the base portion 11 and is not clearly defined. However, the base portion has a height of about L / 2 from the shoe sole portion 5 side with respect to the total length L of the bending member 6. 11 and above that is the bent portion 12. The bending member 6 is formed so as to become thicker and wider toward the base 11 side, and the base 11 side has a higher elastic modulus (Young's modulus) than the bent portion 12 side (it is difficult to bend). .

  The base 11 is composed of a lower portion 13 and an upper portion 14. The lower portion 13 is formed wide (about 50 mm) and thick (about 10 mm), and the width W of the bending member 6 in FIG. 2 is constant. A tongue portion 15 is formed at the lowermost portion of the lower portion 13 so that when the bending member 6 is attached to the heel portion 4, the bending member 6 conforms to the insole 7 of the shoe 1. The tongue 15 extends about 5 mm in the thickness direction of the bending member 6, and the tongue 15 smoothly connects the insole 7 and the inner surface 6 a of the bending member 6. The discomfort caused by the bending member 6 when putting on is suppressed. In addition, it is needless to say that the dimensions of each part are an example and can be appropriately changed according to the size and the shape of the shoe.

  The upper portion 14 is integrally provided above the lower portion 13 and has a narrower width and a smaller thickness toward the upper side. At the boundary between the base portion 11 and the bending portion 12, the thickness of the bending member 6 is about half (about 5 mm) of the lower portion 13. As shown in FIG. 3 (a), the lower portion 13 and the bent portion 12 are continuous and tapered in width, and the uppermost portion of the bent portion 12 is an upper surface portion having a width of about 4 mm and a thickness of about 1 mm. It is sixteen. That is, in the bending member 6, the lower portion 13 and the bending portion 12 as a whole have a small isosceles shape of a small upper base close to a triangle.

  As shown in FIGS. 3B, 4A, and 4B, the bending member 6 is curved in an arc shape along the width direction and the vertical direction as a whole. The width direction is curved so that the rear side of the shoe 1 is convex, the center part is thickest, and the thickness decreases toward both sides. Also, the rear side of the shoe 1 is curved in a convex shape in the vertical direction, and the front end portions of the upper surface portion 16 and the tongue portion 15 are arranged on substantially the same perpendicular line P. In this way, by bending the entire bending member 6, the bending member 6 can be fitted to the inside of the heel part 4, and the presence of the tongue part 15 is combined with the shoe user to feel a foreign object. It becomes possible to arrange the bending member 6 in the shoe 1 in the absence state.

  FIG. 5 is an explanatory view showing the condition of the buttocks 4 when the user puts the foot 8 in the shoe 1. In the shoe 1 provided with such a bending member 6, the user puts the foot 8 in the footwear 3 by stepping on the upper part of the buttocks 4. Then, the upper part of the buttocks 4 is pressed by the user's beak and is bent inward (FIG. 5 (a)). At this time, the bending member 6 disposed inside the collar portion 4 is also pressed and the entire bending member 6 is inclined, but the base 11 side is not bent due to the difference in elasticity between the upper and lower portions of the bending member. Is held, and a portion on the side of the bending portion 12 (a portion above approximately one half of the entire bending member) is bent inward.

  Then, when the foot 8 is fitted into the shoe 1, the bending portion 12 which has been bent inward returns to its original state by its own elastic force (FIG. 5 (b)). As a result, the buttocks 4 are restored to the original shape, and the user can wear the shoes 1 while standing, without using a shoehorn or the like. In addition, according to the inventor's prototype experiment, when the bent portion 12 extends from the bottom of the bending member to 1/3 or less, the recoverability is reduced, and the bent portion is difficult to return or may not return. . Also, when the width of the top of the bent portion 12 is wide or thick, the restorability also decreases.

  That is, in the shoe 1, when the shoe user puts the foot 8 in the footwear opening 3 by arranging the bending member 6 having portions with different elasticity in the upper and lower portions, the bending above the bending member 6. After the portion 12 side is bent inward and the foot 8 is accommodated in the shoe 1, the bent portion 12 side elastically returns. Under the present circumstances, even if the shoe user bends the foot 8 in the footrest 3, the base 11 side located below the bending member 6 does not bend and supports the bending part 12, and only the bending part 12 side bends. Then, when the restraint on the side of the bending portion 12 is released, the bending member 6 immediately returns to the original state.

  Thus, in the shoe 1 of this invention, the bending part 12 side is easy to return to an original state sensitively, and there is no malfunction that the return of the flexible member arranged in the heel part is bad like the conventional shoes. That is, when the foot 8 is fitted into the shoe 1, the buttocks 4 are quickly restored to their original shape. Moreover, since the bending member 6 is a flexible member that is curved as a whole, it is easy to become familiar with the inside of the collar part 4, the foreign object feeling of the collar part is suppressed, and the wearing feeling is improved. Therefore, according to the present invention, it is possible to provide a shoe which can be worn easily by elderly people and the like, and which can be worn without feeling of foreign matter.

  Further, in the shoe 1 of the present invention, elastic recovery of the heel portion 4 can be achieved without making a hole in the heel portion 4. Therefore, it is possible to support the foot without exposing the heel to the outside. Furthermore, the shoe 1 does not require a fastener operation at the time of its attachment and detachment, and since there is no failure of the fastener, it is easy to use even for handicapped elderly people, etc. It becomes possible.

Second Embodiment
FIG. 6 is an explanatory view showing a configuration of a shoe 21 according to a second embodiment of the present invention. In the following embodiment, the same reference numerals are given to the same parts and members as those in Embodiment 1, and the description thereof is omitted. In the shoe 21, a synthetic resin support member 23 is disposed on the base 11 of the bending member 22 in order to reduce the weight of the bending member. 7 is a perspective view of the support member 23, and FIG. 8 is a cross-sectional view of the bending member 22 (corresponding to a cross section taken along line AA in FIG. 1). The support member 23 is formed of a material having a specific gravity smaller than that of the material of the bending member 22 (synthetic rubber) (synthetic resin such as polyamide or polyethylene or wood).

  As shown in FIG. 7, the support member 23 is obtained by replacing the rear portion of the base 11 of the bending member 6 with a lightweight member such as a synthetic resin, and is surrounded by an arc and a string like a mandarin orange bunch. It has become a three-dimensional form of the plane. The support member 23 and the bending member 22 are attached with an adhesive. The base portion 11 is required to have higher bending rigidity than the bent portion 12, but the support member 23 is formed of a hard plastic or the like, and the rigidity of the base portion 11 as a whole is ensured. On the other hand, since the support member 23 is lighter than rubber, the overall weight of the bending member is reduced, and the weight of the shoe 21 can be reduced.

Third Embodiment
FIGS. 9A and 9B are explanatory views showing the configuration of a shoe 31 that is Embodiment 3 of the present invention, and show an example in which the present invention is applied to leather shoes. The shoe 31 is a leather shoe, and as shown in FIG. 9, the upper part of the heel part 4 is cut away to form a section 32 here. A flexible member 33 made of synthetic rubber is affixed to the inside of the section 32. The bending member 33 is fixed to the remaining part (the remaining part 34) of the collar part 4 from which the section 32 is separated. At this time, the section 32 is disposed so as to fit in the original position of the buttocks 4.

  In this case, the position X at which the section 32 is separated is set at a position 2/3 or more from the bottom with respect to the height H of the shoe excluding the sole 5. According to the inventor's prototype experiment, the bending member 33 may not return if it is separated at a position of 1/2 or less from the bottom. In the case of separation at a position of more than 1/2 and less than 2/3, although it returns, the operation is rather sluggish, and the position X is preferably 2H / 3 or more from the bottom.

  FIG. 10 is an explanatory view showing a configuration of a bending member 33 used for the shoe 31. As shown in FIG. As shown to Fig.10 (a), the bending member 33 is formed in the substantially triangular shape which thinned Mt. Fuji. The bending member 33 is also curved in a bow shape along the width direction and the vertical direction as a whole, similarly to the bending member 6 described above. However, in the bending member 33, the thickness of the upper portion of the bending member is set to be larger than that of the bending member 6 because the bending portion 35 to which the section 32 is attached is in the upper direction. That is, in the bending member 6, the thickness of a portion corresponding to the vicinity of the separation position X is approximately 3 to 4 mm, while in the bending member 33, the member thickness at the separation position X is secured about 5 mm. There is. As a result, the elastic modulus of the bending portion 35 is increased, and the segment 32 returns to the original position more quickly. In addition, even if the dimension of the bending member 6 is applied as it is, the section 32 returns without trouble.

  In such a shoe 31, when the user puts the foot 8 in the footwear 3, the section 32 is compressed and bent by the user's heel. At this time, the bending member 33 arranged on the inside of the section 32 is also pressed, but since the heel remaining portion 34 of the leather shoe is hard, the base 36 side fixed to the heel remaining portion 34 is slightly inclined. The state is maintained, and the bent portion 35 side is bent inward with the segment 32. Then, when the foot 8 is fitted in the shoe 1, the bending portion 35 which has been bent inward returns to its original state by its own elastic force, and the buttocks 4 are restored to the original shape. As a result, the user can wear the shoes 31 without particularly using a shoehorn or the like.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
For example, in the above-described embodiment, an example in which a material made of synthetic rubber is used as the bending member is shown, but the material of the bending member is not limited to synthetic rubber, natural rubber, synthetic resin such as silicon, etc. Any elastic material having an elastic repulsive force can be used as appropriate. Further, the shape of the bending member is not limited to the upper member having a trapezoidal shape like the bending member 6, and the whole may be formed in a substantially semicircular shape as shown in FIG. Curved member 41). Furthermore, the bending member 6 of the first embodiment and the bending member 22 + the support member 23 of the second embodiment can be used in the third embodiment. In addition, since the heel portion of the leather shoes is harder than sneakers or the like, the bending member 33 of the third embodiment may be made smaller on the base 36 side as shown in FIG. The bending member 33 can be reduced in weight and material can be saved.
