Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shoe counter, that is, a heel leather,
In particular, it relates to shoes having an exterior heel skin.

Exterior heel skins are known and used in athletic shoes for a variety of reasons, particularly to provide increased support to the foot to counteract the excessive pronation tendency of the foot.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an exterior heel skin that provides dynamic support to the foot that accommodates the movements of the foot when the shoe is worn. This new heel skin has leverage to allow dynamic support. This leverage is generated by a force on a particular vertical rim portion of the heel skin in conjunction with an integral anchor flap portion of the heel skin. The lower part of the rim is subjected to a laterally outward force by the vertically compressed and laterally spread lower sole or bottom, and the upper part of the rim, and thus the top of the shoe, is subjected to a laterally inward force. to temporarily increase the supporting force for the foot.

(Description of preferred embodiment) Preferred embodiments of the present invention will be described with reference to the drawings.

The interlocking competition shoe 10 has an upper or second part 12 of the shoe, a mint sole or middle sole 13, an outsole or outer sole 14 having a tread or inner tread surface 14', and an insole or inner sole 15. ,
It includes an exterior counter-length Wachikaga and skin control JI device 16. The -F section 12 of the shoe extends partially from both sides of the foot to below the ankle, or leaves a space between its edges;
It is designed to accept adhesives such as ethylene hynylacetate. The internal bottom 15 is
1: with adhesive 19, is glued to part 2, where the upper part 12
It is overlapped with the edge of , and is also bonded to the middle bottom 13 . The inner sole 13 is bonded to the outer sole 14 in a conventional manner. The upper part 12 is glued to the abutting inner wall surface of the upper part of the heel skin device 16. The lower part of the heel skin device abuts the periphery of the midsole 13 and is glued thereto. , the adhesive is ethylene vinyl acetate or its equivalent. The midsole 13 is made of a compressible, resilient polymeric material such as conventionally used porous rubber.

Heel skin control device 16 includes a molded polymeric material, preferably graphite reinforced nylon. Its shape consists of a curved section that extends around the heel of the shoe, and a generally linear section that extends forward toward the instep of the shoe along both sides of the center of the shoe.
Contains two parts. The heel skin 16 includes an essentially vertically oriented outer rim portion lea and an inwardly projecting anchor flange portion 16b, the former extending around the outer periphery and the latter extending around the rim portion. It is within the middle of the , and stands out from it. The forward portion of the flange portion 16b is integrally interconnected with the transverse bridge portion 18c. This bridge therefore connects the anterior regions of the heel skin and prevents them from widening and separating under the influence of outward lateral forces on either side of the rim. The flange portion 18b and the bridge portion 16c include
Several through-holes 17 are provided, through which the adhesive between the midsole and the shoe upper extends in the form of small stakes, providing an anchor or fixation for the heel insert. are helping. The rim portion 18a is an anchor flange portion l.
Extending above and below eb. Side part of rim part
lea maintains a vertical orientation with respect to its front end. The mid-section side 16a of the rim maintains a fully vertical orientation, with the exception of its forward part le within the mid-region of the shoe.
In a, it is inclined at an acute angle, and at the same angle the upper part of the rim part is inclined outwardly and the lower part is inclined outwardly. This ensures full contact with the sloped shape of the shoe's upper region in the upper region of the shoe, while maintaining its basic vertical orientation.

The anchor flange portion tab has a relatively thick and stiff region where the flange portion joins the rim portion and tapers to a thinner and more flexible portion towards the mid-section of the shoe. The inner surface of the joint between the rim and flange is concave,
The upper part of the shoe is curved smoothly downward and inward, so that it is almost flat and only one part of the shoe is flat! Immerse yourself in the thinner and more flexible part of the do at l1f1. The rim is sufficiently stiff,
A lateral outward force applied to the lower part of the rim also insignificantly bends the lower part of the rim relative to the upper part of the rim, but rather the force is applied to the entire rim section and the adjacent thicker anchor flange section. (Fig. 7) pivots around a thin anchor flange area designated generally as "P" (Fig. 7).

The heel skin device provides support to the foot in response to dynamic forces. This is extremely difficult for competition shoes, including running shoes, which repeatedly apply considerable force to the sole of the shoe lying beneath the foot, and which has an extremely large tendency to pronate. It is. This dynamic support action is
The sheathing produced by the cooperative action of the outer sole and the upper part of the shoe is accomplished by the lever action of the gait leather. The heel skin device generates a lateral inward support force on the foot in response to downward dynamic forces applied during use of the shoe. That is, as the athlete moves, and in response to forces exerted by the foot on the compressible midsole underlying the foot, the midsole compresses downwardly and expands laterally outward. This lateral expansion creates a lateral outward force against the top of the abutting rim on each side of the center of the shoe. Due to the shape of the heel skin itself and being anchored, the F part of the rim is
1. Spreading and separation is prevented. Therefore, lateral forces tend to pivot the stiff, upright rim and the thicker region of the anchor flange adjacent thereto about the softer region P of the flange, causing the upper part of the rim to An inward force is applied to the central part and both lateral parts of one part of the shoe to support the base of the foot. As a result, dynamic support is applied when it is needed most.

The construction details of this particular shoe can be modified within this new philosophy to accommodate the athlete's specific activity. Therefore, the invention is to be limited only by the claims and equivalents thereof and not by the specific embodiments of the invention shown by way of illustration.
