Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ground-contact sole for general athletic shoes, shoes for construction site work, or shoes for agricultural work, and more particularly, the present invention relates to a ground-contacting sole for general athletic shoes, shoes for construction site work, or shoes for agricultural work. Concerning the large ground sole.

(Conventional technique + Fi) It is generally known that the grip power of athletic shoes on the ground is inferior to that of underground shoes.

This is because in the basement, the parent's shoes and the other four shoes are separated by a fork, so the parent's shoes and the other four shoes can move freely, and as a result, each heel can accurately follow the unevenness of the ground. This is because conventional athletic shoes cannot achieve this effect.

(Problems to be Solved by the Invention) In order to improve the grip of athletic shoes on the ground, it is necessary to change the pattern of the ground-contact sole in the areas where the big toe and other heel areas act, and to improve the grip of athletic shoes on the ground. Athletic shoes containing a plate-like member corresponding to the above have been proposed in the past. These improvements in athletic shoes have not done much to improve grip. In addition, athletic shoes with forks similar to underground shoes have been proposed, but these are well known for their sleek appearance.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a ground-contact sole for footwear that maintains the sleek appearance of conventional athletic shoes while exhibiting greater grip than conventional athletic shoes.

(Means for Solving the Problems) According to the present invention, the portion of the ground sole of footwear on which the positive part rests is formed as at least one ground sole piece independent of the ground sole body, and the ground sole body and the ground sole body are formed as at least one ground sole piece. and are connected via a flexible connecting web, whereby a portion of the footwear sole on which a toe rests can move substantially independently of the footwear main body. is provided.

(Function) In the grounding sole of the present invention, the big toe grounding sole and the four heel grounding soles can move independently of the grounding sole body in accordance with the movement of the stop.

(Example) Examples of the present invention will be described in detail below with reference to the accompanying drawings.

As can be clearly seen from FIGS. 1 and 2, which illustrate a first embodiment of the present invention, a grounding sole body 1 made of a material such as rubber
has a grounding bottom piece 3 for the parent ID on which the parent mark 2 rests, and a grounding bottom piece 5 for the four toes on which the four-toed marking 4 rests, and between these grounding bottom pieces and the grounding sole body 1, there are respective grounding bottom pieces. A flexible connecting web 6 is provided so that it can move independently with respect to the ground sole body 1. This flexible connecting web 6 is thicker than other parts in order to further increase flexibility. It is preferable that the member is thin and has a U-shaped cross-section. Grounding sole piece 3 for big toe
and the grounding bottom piece 5 for all four toes. A cushion 10 made of trousers or the like is attached to the insole of these shoes to improve contact with the heel. The peripheral portions of these insole extend beyond the flexible connecting web 6. Moreover, these inner soles are firmly connected to the grounding sole piece 3 for the main gong and the grounding sole piece 5 for the four toes, respectively.

A part of the grounding sole body 1 protrudes inward from between the grounding bottom piece for the main gong and the grounding bottom piece for the four toes to form the prong 9, and because of this text, the parent 1711: 2 and the four toes 4. is separated inside the shoe. The hanging cloth is for hanging the upper part of the heel and arch of the ground sole, and has adhesive applied to its periphery.

In addition, in order to hang the parent's stop and all four heel areas, a number of zigzag traps 19 are placed around the periphery of the upper in these areas, and a hanging thread is passed through them. The hanging of this part is completed by tying both ends of the thread.The hanging thread is pulled out after gluing the upper and the ground sole.The upper 11 is glued to the ground sole main body 1 and the periphery of the shoe. It is.

As mentioned above, since the grounding sole piece for 11 gongs and the grounding sole piece for all four toes are connected to the grounding sole body via a flexible connecting web, the big toe part and the four heel parts can move freely, respectively. I can do it. This can be best understood by referring to FIGS. 3 and 4, which illustrate the movement of the 11th section. Needless to say, the 47 Hf region can also move in the same way as the big toe region. In this way, Ill,
Since the heel and/or heel can each independently protrude downward as necessary, each gong can accurately grasp the unevenness of the ground, and as a result, the grip force on the ground is greater than before. It becomes larger than that due to the bottom of the ground.

Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6.

The grounding sole according to the second embodiment of the present invention has the adjacent ends of the big toe grounding sole piece 3 and the four-socket grounding sole piece 5 extended in the vertical direction, and the ends of these vertically extending portions are This embodiment is substantially the same as the first embodiment except that the prongs 12 are formed by connecting them to each other.

Therefore, the independent movement of the grounding bottom piece 3 for the main gong and the grounding bottom piece 5 for the four-swing gong is more restricted than in the first embodiment, but since there is no misalignment between the prong and the heel in contact with it, this It is possible to prevent misalignment in parts.

FIG. 7 shows a third embodiment of the grounding sole for footwear according to the present invention, and according to this embodiment, the grounding sole piece for the main gong and the grounding sole piece for the four-socket gong are integrally formed. The toe grounding sole piece is connected to the grounding sole body 1 via a flexible connecting web 6.

FIG. 8 shows a fourth embodiment of the grounding sole for footwear according to the present invention. According to this embodiment, a ball of the big toe grounding sole piece is newly provided at the base of the big toe, A total of three grounding sole pieces, including the toe grounding sole pieces and the four heel grounding sole pieces, are connected to the grounding sole main body l via the flexible connecting web 6.

In the first to fourth embodiments described above, instead of the flexible connecting web 6 described and illustrated as a thin U-shaped member formed of the same material as the ground sole body, the flexible connecting web 6 shown in FIG. As shown in FIG. 10, a flexible connecting web I5 in the form of a thin plate may be adopted, or as shown in FIG. It may also be configured such that a thin walled portion constituting the lower portion acts as a buffer. Alternatively, as shown in FIG. 11, a flexible connecting web 17 made of a material that is more flexible and stretchable than the ground sole body 1 may be bonded to the ground sole body 1.

In athletic shoes having a grounding sole configured according to the present invention, the parent ID grounding sole piece and the four toe grounding sole pieces each move independently with respect to the grounding sole, so each placing part is connected to the ground via the grounding sole piece. It is able to accurately capture irregularities, and as a result, it can exert greater grip than conventional athletic soles with a single-piece ground contact sole. The fork prevents the heel from sliding sideways inside the shoe. It also functions to effectively transmit the force of each heel to the ground via each ground contact sole.

In this way, while having the functionality and comfort of jikakubi, since there are no cracks in the appearance, the smart appearance of conventional athletic shoes is not lost. In addition, while conventional athletic shoes restrict the free movement of each stop, the athletic shoes with a ground-contacting sole configured according to the present invention restrict the free movement of each stop.
! The heel and the four legs can be moved up and down independently, allowing the feet to fully utilize their original functions when walking.

Therefore, compared to conventional athletic shoes, they also have the advantage of being effective for healthy foot development.
