Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to athletic shoes, and more particularly to a moon-shaped core reinforcement for use in athletic shoes.

Modern athletic shoes must all work together to support and protect the foot during athletics.
It is an extremely sophisticated combination of many elements of special functionality. The shoe is divided into two general parts: the upper and the sole. The upper is designed to wrap around the foot snugly and comfortably.

Typically, this upper has a weather-resistant, abrasion-resistant outer layer of leather or a synthetic material such as nylon, and a soft, padded inner layer for good footwear. It will have several layers including. Typically, modern carapaces have an intermediate layer of synthetic foam material. The six layers of the upper may be fastened together by stitching, gluing, or a combination thereof. In areas of greatest wear or stress, reinforcements consisting of leather and/or plastic are applied to the upper. An example of this kind of reinforcement is a leather toe section fitted over a synthetic inner layer in the toe area and a blade-shaped core consisting of an inner layer of plastic and an outer layer of leather.

The other main part of an athletic shoe is the sole. To be constructed as a multi-mile lining, a copper wall must have a very durable bottom surface for contact with the earth. However, since this second-second contact is likely to be made with considerable force, the sole must also have a shock-absorbing function to protect the feet and legs. Thus, soles typically include a resilient, energy-absorbing material as a durable lower surface, i.e., an intermediate sole, in addition to the outer sole. This is especially true for Zoyoyoung shoes or training shoes that are designed to be used over long distances and for long periods of time.

The normal movement of a typical runner's legs during running progresses as follows. First, the heel strikes the ground, the foot shifts forward so that the toe makes contact, and finally the entire foot leaves the ground to begin another cycle. While the foot is in contact with the ground, the foot is typically translocating from the lateral or lateral side to the medial or medial side. This is called pronation. That is, usually the outside of the foot hits the ground first, and the inside toe of the foot leaves the ground last.

While the foot is in the air and preparing for another cycle, the opposite process occurs, called supination. Pronation, 1 - the inward rolling of the foot in contact with the ground, is normal but can be a potential source of foot and leg injury, especially if excessive. The blade-shaped core, a relatively stiff plastic material that gives shape to the carapace in the area of the carapace, provides some stability to the carapace and allows for pronation. can. However, this type of plastic blade-shaped core material has a tendency to weaken after a certain period of use.
As a result, the stability and pronation control of this blade core is reduced.

In the prior art, attempts have been made to solve the within-one interlocking problem in a number of ways. One example of a prior art device directed to the problem of pronation is Forton's American Ff.
No. 4,288.929. The specification of this Norton US patent states: Iil! motion 41
It describes an "interlock control device" located between the upper and the sole at the rear of the 1L.

The control device includes a flat base extending below the upper part of the carapace and a wall that rises from the edge of the flat base and surrounds a portion of the upper part.

In one embodiment, the "bi-base" extends entirely between the side walls and the intermediate tt, and in another embodiment, the slot and notch extend through the base. extending in the direction. This motion control device is constructed from an oil permeable but relatively tough material and is designed to introduce some resistance or resistance to counteract the normal pronation movement of the foot. ing. This device is therefore relatively rigid.

Moreover, there is some degree of coupling between the motions on the intermediate and opposite surfaces.

This is especially the case in embodiments in which the base extends completely between the sides and the intermediate surface. Further, the natural expansion and contraction of the side surfaces of the shoe during running is suppressed to some extent by such a relatively heavy and rigid interlocking control device f.

In other prior art shoes, a wedge-shaped bead of resilient material is placed between the upper surface of the resilient midsole layer and the upper about the periphery of the shoe. The stability with ＼ is improved. The bead provides additional support to the blade core along areas of greatest stress so as to reduce the problem of premature fatigue of the blade core.

SUMMARY OF THE INVENTION An athletic shoe in accordance with the present invention includes an upper covering an outer surface and an inner surface. A blade-shaped core provides shape to the upper in the area of the circumference 9 of the collar and around the collar in order to provide a degree of stability to the wearer of the shoe during running. It is attached to the carapace in the area of A sole is fixed to the upper. The sole includes an outer sole for contacting the ground during running, and a resilient, cushioned intermediate sole layer secured between the upper and the outer sole. A crescent-shaped core reinforcing member made of a high-strength material is attached to the shoe and extends from the lateral side of the shoe around the back of the shoe to the medial side. The reinforcing member has a vertically extending wall and a horizontally extending mounting flange. The above-mentioned mounting flanges are installed several times in the middle bottom layer.

The vertical wall overlaps a portion of the lateral sides of the upper to provide lateral support to the upper, and the upper portion cooperates with the intermediate sole to support lateral displacement during foot strike. In order to resist the above-mentioned intermediate bottom layer, the intermediate bottom layer has a lower part formed by one part 81S of the side surface thereof.

The shoe according to the invention also includes a blade-shaped core defined around the upper area.

This moon-shaped core is formed from a relatively stiff material and gives a permanent shape to the surrounding carapace, providing some degree of control or stability and force). Therefore, a protective membrane is used to reduce the adverse effects of pronation.

In a preferred embodiment of the invention, the middle side of the U-shaped moon core reinforcement is longer and has higher walls than either side. This provides increased control over rolling on the side where control is most needed.

The lunar core support Ujl is constructed from a relatively stiff but flexible material to provide some control over rotation while still allowing some freedom of movement. 7 lunges tightened at [tll] between the upper and the sole of the shoe are +frJ
The moon-shaped core supplement! Fix the ij1 member to the shoe.

As the carapace rolls to one side, it presses against the wall of said moon-shaped core reinforcement; this force is also transmitted to the lower part of said wall, which lies on said midsole. be done. The lower portion of this wall presses into the intermediate bottom layer and provides resistance to further transfer interlocks.

The present invention is a pronation Mii that you can use while running! I am trying to increase the control of II. This means that the reinforcing part H is lightweight and inexpensive, and is constructed in such a way that interlocking movements other than pronation interlocking are unnecessary.
This is achieved through the use of . Due to the shape and arrangement of the reinforcing parts, upper 41-! The reinforcement part is r acting on the blade-shaped core material.
rb, the force is reduced and the durability of the -F log type core 5
It is extended and cooperates with the blade-shaped core and the cushion midsole so that the tendency of the moon-shaped core H to prevent pronation is extended and promoted. During interlocking, the foot rolls from the lateral side to the middle side, so the reinforcing member rolls further forward on the middle side, causing the middle 11+ of the shoe! Increases resistance to physical foot transfer. The above-mentioned reinforcement NIS is relatively small in size and cooperates with the middle 171J sole layer, so the reinforcing member mentioned in - 101 enhances the control of interlocking in 101, and at the same time 116 expands and contracts the sides of the upper of the shoe. Adapt to bending.

The upper has the specific function of providing light, comfortable, and sheltered ground during running. For this purpose, this carapace has several layers, e.g.
It may also consist of an inner layer of breathable woven nylon, an intermediate cushioning layer of foamed rubber, and an outer protective layer of tightly woven nylon. At points where there is extreme wear or where increased protection or stiffness is required, such as on the front of the toe box and on either side of the upper, the leather layer is glued to the jacket. It may be fastened to the outside of the upper.

The function of the sole is to resist abrasion while in contact with the ground, withstand the forces generated when the foot is striking the ground, cushion the impact of the foot, and protect the runner from injury and fatigue. It is to be. This sole also provides a wide, stable base 1 that supports the scale in contact with the ground. This generally includes a relatively stiff lower sole outer layer with a contoured sole surface to increase traction and reduce the impact generated when the foot strikes the ground. and a relatively soft, energy-absorbing intermediate layer to which the shoe upper is attached. For increased stability, the bottom surface of the sole is made somewhat wider than the foot; the midsole of the sole is then tapered inwardly toward the top;
The width at the point where it is fastened to the upper of the shoe is the same as the width of the upper of the shoe at said point. Thus, a wedge-shaped bottom is formed with the 9th section at the top and the sides sloping inwardly from the bottom to the top and wider.

The various advantages and features of the new product which characterize the invention are pointed out with particularity in the claims appended hereto and forming a part thereof.

However, for a better understanding of the invention, its advantages and the objects achieved by its application, reference may be made to the accompanying drawings, which illustrate preferred embodiments of the invention, and to the text description thereof. It should be.

Refer to the accompanying drawings in which like numerals indicate like elements.
1, an athletic shoe according to the present invention is shown generally at 10.

An upper 12 extends completely around the foot and includes provision for a lace 14. The upper 12 has one or more reinforced sections 16, 17 in areas of high stress that are sewn to the outside of the upper 12 with leather or some other durable material sewn to the outside of the upper 12. 19. The reinforcing portion 19 is in the form of a conventional moon-shaped core comprising an inner layer 21 made of a relatively stiff material, such as a hard plastic, and an outer cover layer 23 made of leather. ing. If possible, the upper 12 should be attached to the inner liner 27
, an intermediate layer 29 of foam cushioning material, and an outer layer 31 of a tightly woven synthetic material. The six-layer carapace is described in U.S. Pat. Nos. 3,793,750 and 4
．． No. 255,876, each specification 4i.

The sole 18, which is attached to the bottom of the upper 12 by prior art methods, is generally comprised of at least two M, including an outer sole layer 20 and an intermediate sole layer 22 of the shoe. The outer sole layer 20 of the shoe has its sole surface contoured to increase traction. The outer sole layer is constructed of a relatively hard, resilient material so as to be sufficiently resilient in contact with the ground being deflected. The intermediate sole layer 22 does not need to be hard, but should be made so that the foot and leg are connected to each other.
It should have a cushioning effect to absorb running shocks (α). Thus, if possible, the intermediate bottom layer 22 should be made of Shore A guerre and have a hardness within the range of 2o to 55 durometer. A resilient cushion such as EVA, foamed polyurethane or foam is preferably formed from an encapsulated air cushion.

Referring now to FIG. 2, the relationship of the moon-shaped core reinforcement 24 to the upper 12 and sole 18 is clearly illustrated. After the shoes? At Is 1.5, a moon-shaped core bolt 24 is fastened between the upper 12 and the intermediate bottom layer 22. In plan view, the moon-shaped core reinforcement 24c is the horizontal support or mounting flange 28, and the vertical wall 26 is
It has a U-shape. The vertical wall 26 is integrally formed with the flange 28 and has an upper portion 33 extending perpendicularly upward from the outer edge of the flange 28 and from the outer edge of the flange 28! It has a lower portion 35 extending vertically downward. Horizontal 7 Ranzo 28 is carapace 1
2 and the upper surface of the intermediate sole 22 .

7 lunge 28, if possible, carapace 12 of 7 lunge 28.
Preferably, it is fastened in place to the midsole 22 by adhesive on three sides.

It is also preferred that the inward surface of the three-sided portion 33 of the vertical wall 26 is also marked several times on the outer surface of the upper 12, preferably by means of an adhesive. In this way, the moon-shaped core reinforcement 24 is attached to the shoe 10. A vertical wall 26 extends perpendicularly to the top of the bamboo, i.e., not precisely, but following the upper limit of the heel area of the carapace. Intermediate bottom j11I'
The bottom of 1i22 is somewhat wider than its top; as a result both sides of said bottom 1r1i 3-2 must slope inward from the bottom to the top. The inner surface of the lower surface of the lower portion 35 of the vertical wall 26 is sloped to match the slope of the intermediate bottom layer 22. The moon-shaped core reinforcing lever 24 cooperates with the moon-shaped core material 19 and the intermediate sole 22 to control the intra-disc movement. As described in the background of the present invention, the moon-shaped core reinforcement 19 controls the pronation movement. Provides some degree of control. However,
After a certain period of time, the typical moon-shaped core weakens, resulting in a reduced degree of control. Depending on the phase used to make this moon-shaped core, the above-mentioned weakening may occur even after about 100 miles of running.

The twenty-fourth aspect of the moon-shaped core reinforcement of the present invention is to extend the time for effectively controlling the shape of the moon-shaped core material, thereby increasing the strength of the shoe.
and increase blood stability throughout the function. This is due to the particular location, size, shape and hardness of the moon-shaped core reinforcement and the manner in which the moon-shaped core reinforcement interacts with the moon-shaped core reinforcement 19 and the middle 1m layer 22. This is achieved in a light and effective manner by means of the moon-shaped core reinforcement 24.

The upper part of the wall 26 extends around the lunar core 19 along the area of maximum stress of the lunar core 19 during running.

<L-c% This upper portion 33 provides reinforcement in the area of maximum stress. Due to the interaction G of the lower part 35 of the wall 26 with the intermediate sole j·n 22, the stress on the moon-shaped core 19 is further reduced by an additional amount O.

During running, the foot exerts a force on the shoe shown in FIG. 5 from Fm and Fl&. In this case m indicates the medial side of the shoe and 1 indicates the lateral side of the shoe.

When one of these forces, for example Fm or shoe G, is applied, this force is transmitted to the upper part 33 of the wall of the moon-shaped core reinforcement 24, which due to its quality pJ will respond to the force Fm to some extent. resistance. Force Fm is also transmitted to the lower portion 35 of the vertical wall 26. The force transmitted to the lower part of the wall 26 is transferred to the side surface 3 of the intermediate sole j, j22 on which this lower part rests.
2.

A lower part 35 having a height of 6.2 Te has been found to be sufficient for this purpose. therefore,
The leftward and downward force Fm is caused by a number of factors: the relatively rigid moon-shaped core 19, the upper portion 33 of the wall 26 and their interaction, and the moon-shaped core reinforcement with the intermediate bottom layer 24. 2
4 is controlled by the interaction of the lower part 35 of 4. The moon-shaped core reinforcement 24 similarly acts on the lateral sides of the shoe when the foot applies a force shown at F'l in FIG. This interaction resists the forces Fm, Fl, and as a result, the bending of the moon core is reduced, thereby reducing the stress acting on the moon core 19 or the tendency of the moon core 19 to break. Reduce.

Referring now to Figures 31 to 81, various features of this preferred embodiment of the invention are illustrated. More control is appropriate for the medial or medial side rni since the foot rolls from the lateral side to the medial side during contact with the ground during running. In this preferred embodiment of the invention, the moon-shaped core also has 11 reinforcements 2
4 extends further forward along the medial side of the shoe than along the lateral sides. The inner wall 26m has a counter-roofed lateral part 26m and 2
Longer than 81. For example, a distance a of approximately 79.4 mm between the rearmost inner surface of reinforcement 24 and the leading edge of wall 26m.
A distance of about 61.9 van between the rearmost inner surface of the stiffener 24 and the front edge of the side wall 281 has been found to be adequate for a human shoe of size Jθ. The length of the moon-shaped core reinforcement 24 on the inner side increases the resistance associated with foot roll on that side. In Figure 3, C1 arch JP; ? t1s, that is, roughly the part 3; which curves inward at the boundary between the sole and the upper of the shoe.
6. The starting point of said inward curve, i.e. the starting point 38 of said arched portion 3 (i), is illustrated as the preferably forward limit of the inner portion of the moon-shaped core reinforcement 24.

One additional feature of this preferred embodiment of the invention is illustrated in FIG. Moon-shaped core reinforcement 4,424 walls 26
The majority of the walls have a height I above the top of the 7 runzo 28. In order to roughly additionally control the medial displacement movement of the foot, the side walls 26 m mentioned above have a height slightly reduced. In Fig. 4, the height of ``2'' is shown as H'. Fig. 5 similarly shows the height of the inner wall 26m and the side wall 261.
It also illustrates the height difference between Height I (approximately 9-5m
m, the height difference between heights H and H' is approximately 1.5
9+nm has been found acceptable.

Features of this preferred embodiment of the moon-shaped core reinforcement 24-
-j is the combination of flexibility and control. The flange 28 may be relatively narrow, for example 12. ! by making the flange slightly larger than 5 mm, by introducing a radial notch 34 in the flange 28, and by making the 7 flange relatively thin;
For example, by making the moon-shaped core reinforcing material 24 sufficiently flexible by changing it from 5 nun to 1.0 nun, the foot can be
111+! It is possible to avoid limiting it to one size.

The notch 34 is located within the curved rear portion of the 7 flange 28 and is located at the center point P of the curved portion of the lunar core reinforcement.
The notch is oriented toward the radial direction and is therefore called a ``radial'' notch. 7 Lunge 280 Width B is the moon-shaped core reinforcement 240 In order to preserve flexibility, the width I- of the shoe upper 12 is also wide.
Should be only minutes. 7 lunge 28 III! j
It has been found that the required flexibility exists if B is at most 4 times the width A of the widest point of the upper of the shoe. The two sides of the moon-shaped core sleeve assault 24 have different vertical IUs.
Act independently on each other when a force is applied. Thus, there is virtually no coupling between the vertical movements on the lateral and medial sides of KA\ produced by reinforcement A24.

During running, the forces 'Fm and Fl (Fig. 5) are applied simultaneously because the rotation of the foot strike expands both inwardly and outwardly. It is desirable not to unnecessarily restrict this natural expansion of the foot, IJ, and thus the moon-shaped core reinforcement of the present invention allows this to occur at will.

That is, the aforementioned features of the moon core reinforcement that make it more flexible also accommodate compression and expansion flexures on both sides of the leather upper.

By providing the notch 34 in the flange 28 and keeping the width of the flange as small as possible, the weight of the moon-shaped core reinforcing material 240 can be reduced to a minimum of one stitch. Another way to minimize the weight of the reinforcement is to make the reinforcement from a lightweight material. They must be relatively rigid to allow the feet to move easily, yet be flexible enough to allow for comfortable movement of the foot. Polyurethanes of 80 Shore A durometer have been found to be particularly suitable.

The numerous features and advantages of the invention are set forth in the foregoing description, as well as details of its structure and function, and the novel features are pointed out in the appended claims. However, the foregoing description is illustrative only and, therefore, it is intended that the principles of the invention be detailed in detail, particularly in the shape, size and arrangement of parts, to the fullest extent indicated by the broader meaning of the term in which the claims are set forth. Changes can be made regarding. For example, although the moon-shaped core reinforcement is illustrated in the context of a shoe made to fit a right foot, the present invention is equally applicable to both left and right shoes. The moon core reinforcements on both shoes would be mirror images of each other.
