Description

TECHNICAL FIELD The present invention relates to a shoe equipped with a heel system in which a heel and a counter are integrally molded, and the heel system.

In general, in order to prevent the heel part from losing its shape and to reinforce the stability of the shoe and the foot during running or walking, there is a gap between the outer leather and the lining leather in the part of the instep that surrounds the heel. A reinforcing member called a counter is inserted. Since the counter is a reinforcing member for preventing the heel portion of the shoe from losing its shape and ensuring stability, it is often made of a hard material such as hard resin (for example, Patent Documents 1 "0007" and "0025"). ∼ see "0041" and "Fig. 1") .

There are two main problems with such conventional shoes.

(1) First, the shape of the curve in the heel portion of the shoe does not match the shape of the heel of the wearer of the shoe, especially the shape of the counter member inserted between the outer leather and the inner leather of the instep of the shoe, Injuries such as blisters, swelling, etc. caused by the movement of the wearer's foot in the shoe or by the localized load on the heel part (especially the end of the counter member) on the wearer's foot. was the cause of In other words, when purchasing shoes, one usually tries them on, but it is not always possible to accurately judge whether the buyer's feet and the tried-on shoes match in a short-time try-on. , the shape of the curve in the heel portion of the shoe may not match the shape of the heel of the wearer of the shoe.

Furthermore, the shape of a person's foot changes from hour to hour, even during a day, due to changes in the gravity applied to the foot, the amount of water in the vicinity of the foot, and the like. As a result, even if the shape of the shoe fits the shape of the foot when trying it on, the shape of the shoe, especially the heel portion, may temporarily or permanently not fit the shape of the foot.

Thus, when the shape of the heel portion of the shoe, especially the shape of the counter member, and the shape of the heel of the wearer of the shoe do not match, blisters may occur, or a portion of the foot and the shoe, especially a portion of the heel portion, may be damaged. Interference with the thyroid causes pain and may cause swelling and bleeding.

(2) The parts used around the heel of the shoe include many parts such as the heel, heel wrap leather, top lift, counter, etc., and the process of inserting the counter between the outer leather and the lining leather of the shoe is a delicate process. There is also the problem that it is difficult to reduce the cost of shoe manufacturing, such as the cost of materials, because the work is required.

However, except for special shoes such as ballet shoes and driving shoes, generally, a counter is essential for shoes. This is because, in shoes, it is necessary to secure the shape of the heel portion and the stability of the shoe and the foot when the wearer wears the shoe.

Similar to Figures 1-1 to 1-3, Figure 6-1 is a bird's-eye view of the shoe 1, and Figures 6-2 (a) and (b) are side views of the shoe 1 on the lateral side and medial side, respectively. Side views, FIGS. 6-3(a) and (b), are top and bottom views of the shoe 1, respectively. As shown in each figure, the shoe 1 has a heel system 2, an instep 3, and a sole 4, as in the first embodiment.

The difference from the first embodiment of the present invention is the shape of the heel system 2, and this difference will be explained using FIGS. 7-1 to 7-3.

7-1 to 7-3 are diagrams showing the heel system 2. FIG. Figure 7-1 is a bird's-eye view of the heel system 2, Figures 7-2(a) and (b) are side views of the lateral shell side and medial side of the heel system, respectively, Figures 7-3(a) and (b) ) are top and bottom views of the heel system, respectively (however, the counter portion of the heel system is omitted for clarity of the drawing). As shown in each figure, the configuration of the heel system 2 is the same as the contents described for the first embodiment of the present invention in "0041" .

As shown in FIGS. 7-1 to 7-3, the configuration of the heel portion 21 is the same as that described for the first embodiment of the present invention in "0042", "0043" and "0044" .

The contents of the configuration of the counter part 22 and the counter wall part 221 are basically the same as the contents described in the first embodiment of the present invention in "0045" and "0046" . As a configuration specific to the second embodiment of the present invention, an opening 222 is provided in the rear portion of the counter wall portion 221 . For example, the opening has a substantially trapezoidal or triangular shape with the base on the lower side.

Regarding the effect of the heel system 2, as in the first embodiment of the present invention, it is integrally molded using resin and attached so as to cover the heel part of the instep of the shoe from the outside, It wraps the wearer's heel through the back leather. Then, since the outer leather and the lining leather of the instep part function as a cushioning material between the counter part of the heel system part and the wearer's heel, the flexibility of the heel part of the shoe of the present invention is secured, It is possible to fit the shape of the heel portion of the shoe to the heel of the wearer while absorbing the difference in the shape of the heel of the wearer. In addition, since the counter wall portion 221 is made of resin, it deforms according to the shape of the rear portion of the instep portion 3 and the shape of the heel of the wearer, and fits the wearer's foot. It is possible to achieve better wearing comfort. Furthermore, by using a highly flexible resin with a Shore A hardness of 50 to 70 as the material for the heel system 2, the heel portion and the heel system portion of the shoe are integrated to ensure the stability of the wearer's foot . It becomes more flexible and easily deformable according to the shape of the heel of the wearer's foot. In other words, it is possible to secure a higher degree of flexibility of the heel portion of the shoe, to more flexibly absorb the difference in the shape of the heel portion of the shoe from the shape of the heel of the wearer, and to fit the heel of the wearer better. Therefore, extremely good comfort can be obtained. That is, a Shore A hardness of 50 to 70 is optimal for ensuring both the stability of the wearer's foot and the flexibility of the heel portion of the shoe.

Here, the effects peculiar to the second embodiment of the present invention, which cannot be seen in the first embodiment of the present invention, will be described with reference to FIGS. 9(a) and 9(b). The respective instep portions 3a and 3b in FIGS. 9(a) and (b) differ in the radius of curvature of the respective rear instep side walls 311a and 311b. That is, the radius of curvature of the rear instep side wall 311a in FIG. 9(a) is larger than the radius of curvature of the rear instep side wall b in FIG. big). However, the shape of each heel system 2 in FIGS. 9(a) and (b) is identical. In this way, for the instep part 3 having a different shape of the rear instep side wall part 311, since the opening 222 of the heel system 2 can absorb the difference in shape, it is possible to combine the heel system 2 with the same shape. can be done. In other words, for example, even with the same women's pumps, the shape around the heel may differ depending on the design, size, and main intended use. Since it can absorb the difference in shape due to different shapes and can be used for shoes of various shapes, it is possible to greatly reduce the manufacturing cost of shoes.

Furthermore, the effects specific to the second embodiment of the present invention will be described with reference to FIGS. 10(a) and 10(b). 10(a) is a top view of a shoe combining the heel system 2 and the instep 3 of Example 1, and FIG. 10(b) is a shoe combining the heel system 2 and the instep 3 of Example 2. is a top view of the. Since the opening 222 is provided in the counter wall 221 of the heel system 2 of the second embodiment (Fig. 10(b)), the flexibility in the direction of the arrow in the second embodiment (Fig. 10(b)) is The flexibility of the wall portion 221 in the directions of the arrows in FIGS. 10(a) and 10(b) is much higher than the flexibility in the directions of the arrows of the first embodiment (FIG. 10(a)). In that sense as well, the heel system of Example 2 is more flexible than that of Example 1 in terms of the difference in shape of the rear vamp 31 of the shoe 1 and the individuality of the shape of the heel of the wearer of the shoe 1. Since it can be absorbed by hand, the manufacturing cost of the shoe can be greatly reduced, and at the same time, it can provide an extremely high fitting feeling to the wearer's foot and realize an extremely high wearing comfort.

In addition, in Embodiment 2 of the present invention, the shape of the opening 222 is substantially trapezoidal or triangular with the bottom side facing down. As long as it is possible to ensure the shape, there is no particular limitation, and it goes without saying that an appropriate shape can be adopted.

Furthermore, although the first and second embodiments of the present invention are exemplified by pumps for women, pumps, sports shoes, etc. can be used regardless of gender or purpose, as long as the shoes do not have an integrated sole and heel. Needless to say, it can be applied to various shoes.
