Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footrest for footwear and footwear using the footrest, and more specifically, in footwear for women, the foot is stably held without impairing the design. The present invention relates to a footrest base for footwear, which can improve wearing comfort, and footwear using the base.

[0002]

2. Description of the Related Art Among footwear, in particular, women's footwear often has a narrower and healer heel portion than men's footwear in order to make the legs worn long and beautiful. In order to have such a design, in the foot mold of the footrest part,
It is necessary to create a well-balanced and delicate shape by using a narrow width that is balanced with the heel.

Ladies 'sandals are shown in FIGS. 6 and 7 as an example of ladies' footwear. Footwear 11 having such a design
Is basically an inner peripheral side part 15a and an outer peripheral side part 15b that wrap the foot, an abutment part 17 fixed to the heel part 14 for holding a foot, and an upper surface of the abutment part 17 It is formed to include a sole 16 that is attached and faces the sole when worn. The part of the foot pad 17 corresponding to the arch of the foot is particularly narrow and flat, so that the sole of the foot floats from the sole 16 during wearing and walking. (See Figure 8). The footwear 11 formed in this manner is difficult to stably hold the worn foot and does not have a good fit to the foot, so that it is uncomfortable to wear and wears the foot for a long time, resulting in fatigue. However, there is a problem in that it causes keratinization, thickening, and hardening of the skin of various places such as the soles and fingers, which causes fish eyes and octopus.

Therefore, in order to solve the above-mentioned problems and to make the footwear comfortable to wear and capable of stably holding the foot, for example, a cushion material is provided at a portion corresponding to the arch of the footwear. Various attempts have been made to improve the fit and stability by forming the sole part in a structure along the sole of the foot.

[0005]

However, in the above-mentioned attempts, when it is intended to provide such a cushioning material for women's footwear, in particular, by forming an opening or the like on the peripheral side portion that wraps the foot, the peripheral side is formed. In footwear such as sandals that have a design with a reduced area of the part, such a cushioning material is used only in a very narrow and limited sole part corresponding to the arch of the foot with a narrow width as described above. It was only intervened. Therefore, the comfort and the stability of the wearer cannot be improved so much, and the fatigue of the cushion material,
It had a drawback that the initial effect was remarkably reduced with the decrease in elasticity and flattening. Further, as shown in FIG. 9 which is a vertical cross-sectional view, the peripheral side portion 15 that wraps the foot
A structure in which a part of the cushion material 18 is interposed so as to be in contact with both the back surface of the inner peripheral side portion 15a and the footrest portion 12 to hold the arch is also particularly adopted in shoes. With such a configuration, although it is expected that an effect superior to the above example will be achieved,
Even in this case, it is difficult to secure the position of the cushion member 18 for a long period of time depending on the elasticity of the material used for the inner peripheral side portion 15a.
8 could not always be kept in the desired good position against the sole. That is, the portion of the cushion material 18 that protrudes inward from the footrest portion is likely to hang down, and it is often difficult to obtain the desired effect.

[0006] As described above, the requirements for footwear such as stability in wearing and walking, fit and the like, and the design are completely contradictory to each other, and both requirements can be sufficiently satisfied. Things have not been obtained yet.

[0007] Therefore, there has been a need for a means for providing women's footwear with improved comfort, which does not impair the design of the women's footwear and can always hold the foot stably. .

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to stably hold the foot on the footrest of the footwear without impairing the design of the footwear. In order to make it possible, the following features are added to the shape of the footrest part.

That is, the footrest portion of the present invention is a footrest portion for forming footwear, and in addition to a normal foot form,
It is characterized in that it has a protruding hill-like portion that rises obliquely upward from the edge along the arch at the contact surface with the sole of the footrest so as to hold the arch of the foot.

Further, according to the present invention, there is provided footwear characterized by including the footrest part as a constituent element, and the foot can always be stably held without impairing the design of the footwear. , Footwear with improved comfort is provided.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the footrest part of the present invention, the projecting hill portion is made of a material having rigidity enough to support at least weight, and is formed to have a substantially arcuate contour. It is inconspicuous and when worn, the top is completely covered by the foot. Therefore, even if it is used for women's footwear where design is important, the foot can be stably held, which is preferable.

In the footwear of the present invention, the cushioning material is further provided on the upper surface of the footrest to enhance the ability to stably hold the foot, and the wearing comfort is remarkably improved. Since the cushioning material is held by the footrest portion of the present invention at a suitable position with respect to the sole, it is particularly preferable to use the footrest portion of the present invention and the cushioning material together. .

The footwear of the present invention is preferably women's footwear. That is, the contradictory requirements of the women's footwear, which have various problems due to the importance of design as described above, are satisfied by the present invention.

The footwear of the present invention is particularly preferably shoes and sandals. By adopting the footwear regardless of the shape and material of the peripheral side of these footwear, desired effects can be obtained without compromising the design. Obtainable.

Embodiments of the present invention will now be described with reference to the drawings, but the present invention is not limited to these embodiments.

FIG. 1 is a plan view of a female footwear 1 which employs a footrest 2 according to the present invention, and FIG. 2 is a side view thereof. Here, in the footwear 1, the footrest portion 2 is fixed to the heel portion 4, and the peripheral side portion 5 that wraps the foot is formed around the footrest portion 2. The peripheral side portion 5 includes an inner peripheral side portion 5a facing a pair of footwear and an outer peripheral side portion 5b on the opposite side. A foot sole portion 6 having the same shape as the foot rest portion 2 is attached to the upper surface of the foot rest portion 2. A hole 7 is provided in a portion of the sole 6 that contacts the arch of the foot when worn.

The foot pad 2 for constructing the footwear 1 has, in addition to the usual foot shape, a side along the arch at the contact surface with the sole of the foot pad so as to hold the arch of the foot. It is characterized by having a projecting hill portion 3 that rises obliquely upward from the edge.

The foot-shaped portion of the footrest portion 2 excluding the protruding hill portion 3 is similar to the shape of the footrest portion used in ordinary footwear, and the protruding hill portion described below. 3 and the shape and characteristics that are compatible with each other.

The footrest portion 2 may be formed by integrally forming the protruding hill portion 3 or may be formed by separately forming only the protruding hill portion and fixed to the foot portion.

The projecting hill portion 3 is preferably formed so as to have a substantially arcuate contour, and in the plan view, it projects toward the inner peripheral side portion 5a as shown in FIG.
In the side view, as shown in FIG. 2, it slightly projects upward from the footrest portion 2. Further, in order to enhance the fit to the foot, it is preferable that the protruding hill portion 3 has a shape that partially reaches the side surface of the arch of the foot. That is, it is preferable that the arch of the foot is supported laterally.

The projecting hill portion 3 is preferably formed of a material having a rigidity that can support at least the body weight. For example, plastic, steel plate, Nampo (rigid compressed paper (paper press board), leather powder press board). ), Etc., having a high rigidity are partially or entirely covered with a material similar to the material used for covering other components, such as leather, vinyl, synthetic (artificial) leather, etc. Can be used.

The heel portion 4, the peripheral foot portion 5 and the sole portion 6, which are the constituent elements of the footwear 1 shown in FIGS. 1 and 2, may be made of any material that can be used in ordinary footwear.
Each shape can be arbitrarily selected. In addition, the footrest part 2
Including the above, it may be formed integrally as appropriate.

By providing the holes 7 as shown in FIG. 1, the footwear 1 having excellent breathability can be obtained, and when the cushioning material 8 is interposed as described below, An effect is obtained in which air is released when the cushion material 8 is worn and deformed. Aspects such as the size, number, and form of the holes 7 are appropriately selected.

By providing the projecting hill portion 3 on the footrest 2 as in the present invention, a cushion is formed on the upper surface of the footrest 2 including the projecting hill portion 3 in order to further enhance the fit. This is extremely useful because the cushioning material can always be held in a good position when the material is interposed.

It is possible to use one cushion material or a plurality of cushion materials. In particular, the cushioning material placed on the upper surface of the foot contact portion 2 corresponding to the arch should be shaped so that the center portion is thicker than other portions in its cross section in consideration of the fit to the foot. Is preferred.

An example in which two cushion materials are interposed will be described with reference to FIGS. 3, 4 and 5. FIG. 3 is a cross-sectional view taken along the line AA of the footwear 1 shown in FIG. 1 with cushioning materials 8a and 8b interposed therebetween. Cushion material 8a

The cushion member 8a has a leaf shape in plan view (see FIG. 4) and a substantially triangular shape in vertical cross section (see FIG. 5). The second cushion material 8b is a member (see FIGS. 3 and 4) having a constant thickness and having a substantially elliptical plate shape in a plan view.

It is also possible to use an integrally formed cushioning material having such a shape.

As the material of the cushion member 8, for example, a soft sponge or a sponge such as urethane foam, which is exclusively used in the relevant technical field, can be used.

When the cushion material 8 is thus interposed, the footrest portion 2 of the present invention has the protruding hill portion 3 having a rigidity and shape suitable for holding the cushion material 8. Therefore, the position of the cushion member 8 can always be ensured at the best position with respect to the sole of the foot without being affected by the rigidity of the material of the peripheral side portion of the footwear 1.

[0031]

The present invention is carried out in the form as described above and has the following effects.

That is, in the foot contact part for constructing footwear, in addition to the usual foot form, the foot contact part of the foot contact part contacts the sole of the foot so as to hold the arch of the foot. The footrest that has a protruding hill-shaped part that rises obliquely upward from the edge along the edge ensures that the arch of the foot is securely held from the bottom even in footwear with a delicate design such as women's footwear. can do.

Therefore, by adopting the footrest part of the present invention in footwear, it is possible to obtain a good fit to the foot and a good comfort, and to wear it for a long time to cause fatigue in the foot. It is possible to provide footwear in which conventional problems such as keratinization, thickening, and hardening of the skin of various places such as soles and fingers and generation of fish eyes and octopuses have been solved.

In the footrest portion of the present invention, the projecting hill portion is formed of a material having a rigidity that can support at least the weight of the foot, and is formed to have a substantially arcuate contour. By having the above, it is possible to provide a particularly excellent ability to securely hold the above-mentioned arch without any discomfort.

In the footwear of the present invention, a cushioning material may be additionally provided on the upper surface of the footrest part, and the cushioning material is irrelevant regardless of the rigidity of the material on the peripheral side portion, particularly the inner peripheral side portion of the footwear. The material can be always secured in a suitable position with respect to the sole.

As described above, the present invention is extremely useful because it provides footwear with excellent comfort that can stably hold the foot even in the case of women's footwear where design is particularly important. is there. That is, the protruding hill portion,
Since it is formed so as to have a substantially arcuate contour on the inner peripheral side, it is not conspicuous, and when worn, the upper surface is completely covered by the foot. Although the side surface of the projecting hill portion slightly projects from the footrest part, the contour of the side surface of the projecting hill part is a gentle arc, so the shoes whose peripheral side is formed around the circumference of the foot. Other than such footwear, footwear such as sandals having a design in which the inner peripheral side portion has a small occupied area can be used and does not impair the design.
