Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a heel circumferential portion of a shoe, and more particularly to a shoe having a lateral heel circumferential portion.

(Prior Art and Problems) The medial and lateral heel circumferences are known and used for many reasons, but especially in athletic shoes for added support to prevent the foot from falling too low. used for. Such a peripheral area generally extends around the heel of the shoe and upward from the sole to stabilize the foot. Although such line circumferences generally function satisfactorily, several problems are experienced with shoes incorporating line circumferences, particularly after such shoes have been used in combination. A repeated bending of the shoe and sole tends to sever or separate the circumferential portion of the shoe from the sole at the base. Furthermore, with such prolonged use, the base of the heel circumference itself becomes soft, thereby reducing its effectiveness in supporting the shoe.

Such wear and tear on the line area and the shoe reduces the stability and support provided by the shoe to the wearer's foot.

SUMMARY OF THE INVENTION Accordingly, the present invention corrects the above-described problems by providing an lateral semi-rigid circumferential heel support integrally formed with the outsole of the shoe. ζ, new heel/j4 circumferential support + S provides stability to the shoe and the wearer's foot, - works with the rest of the sole and upper part of the shoe to prevent the heel part of the shoe from breaking Let's do it.

The integral lateral heel circumferential support also cooperates with other lateral, lateral or medial heel circumferences to prevent cutting, separation or other disruption and deterioration of the line circumferential portion or shoe of this portion.

These and other features, advantages, and objects of the invention will be further understood by those skilled in the art from the following description, the foregoing claims, and the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the preferred embodiment shown in Figure 1, an athletic shoe 10 is of the type having a semi-rigid outer sole, such as those used in soccer, football, and the like. As best shown in FIG. 5 and FIG. 6, the shoe 10 has an upper part 14 and an inner sole 1.
6, having an intermediate sole 18 and an outer sole 12; An outer semi-rigid circumferential heel support field is integrally formed with the outer sole 12, extending around the side of the shoe after the heel portion. Also, the section lO includes the outer fibers or leather extending over the heel circumferential support part 4, and the inner fibers extending over both the heel circumferential support part and the line circumferential part n after the heel of the shoe 10. It includes a plate or leather part around the heel.

More particularly, the upper part 14 is made of leather or fabric 1 that wraps around the medial heel circumferential portion 24 of the heel area of the shoe 10 shown in Fig. 5 and Fig. 6.
It is of conventional design with two layers of 4 a and 14 b. The upper part 14 extends under the entire circumference of the intermediate sole 18 to form sections of the lower circumference that are glued in place to secure the upper part 14 to the rest of the shoe 1o.

The intermediate sole 18 may be a relatively stiff compressed fiberboard or leather veneer, or may be of a conventional design that lies beneath the entire foot of the person and provides a supporting surface for the medial sole 16. Inner sole 16 is a foam or resilient inner sole fixture having a nylon or other synthetic upper surface that cushions the wearer's foot while also somewhat conforming to the shape of the wearer's foot.

The inner sole is glued to the middle sole with adhesive, and the upper part 14
The troughs 26 are attached to the outer sole 12 as is known in the art. Furthermore, the hard intermediate sole 18 is fixed to the outer sole 12 by means of metal fittings located between the toe and the heel, and in this way the valley is pinned between the intermediate sole 18 and the outer sole 12. are doing.

As shown in Figures 1 and 2 and Figure 3, the outer sole 12 generally comprises a flat, unitarily molded polymer element;
Preferably it has graphite reinforced nylon. The outer sole is a fairly thin layer or lamella of material that forms the body in the form of layers of the outer sole shape.

As shown in Figures 1'5 and 6, an upright ridge 32 with a flat upper support forming a hollow heel portion 34 extends around the rear of the outer sole 12.

A stiff intermediate sole 18 is supported on the planar upper surface of the ridges 32 to provide a flat foot support surface on the inside of the shoe 10.

The raised ridges 32 and hollow heel section give the shoe a raised heel-force while maintaining a relatively light construction. Additionally, the ridges 32 increase and strengthen the molded polymer material in this area so that the outer sole 12 flexes much more easily between the front flat body portions.

In addition, there is a cylindrical plug shown in the figure 2 that protrudes from the hollow heel part 3.
5 and ridges 32.

The plug 35 forms a reinforced base into which nails are fixed and through which the fasteners of the outer and middle soles pass.

As shown in Figure 3, the interlaminar support field is integrally molded with the outer sole 18 from a relatively stiff polymeric material, extends slightly from the ridge 32, and then has a smoothly curved transition section. forming a generally upright peripheral flange 38. The interlaminar surrounding addition extends forward around the rear of the heel area and along both the medial and lateral sides of the lateral sole 12. The interlaminar support ends in a pair of leading edges 4o that define the rearwardly arcuate region of the shoe. The upright 7-shaped curved transition from the upper edge end 42 to the upper edge smoothly tapers towards the upper blade, thus providing the interlayer enclosure support 20 with a generally bowl-shaped, slightly tapering slope towards the upper blade.
It gives an open shape and forms a pocket at the rear of the outer sole.

The outer interlaminar 8 portion or reinforcing element ρ also includes an underlying trough 4 extending below the peripheral edge of the wearer's foot and the heel area of the midshoe tit 18. The valley member is the outer sole ridge 32
and the lower surface of the valley part of the shoe upper 44,
It is pinned between the outer sole 12 and the intermediate sole 18.

As shown in Figures 5 and 6, the interlaminar enclosure portion 22 is supported in contact with the entire inner surface of the peripheral support head.
A relatively thick section of leather or textile fibers that conforms to the curve of the underlying peripheral support head. The textile heel circumferential portion n extends along both the medial and lateral sides of the shoe upper 14, around the rear of the heel area, and extends forward just beyond the leading edge end 40 of the circumferential support head.

The interlaminar surround 4 extends upwardly along the outside of the shoe upper 14 to a generally horizontal upper edge 46 spaced apart above the peripheral support upper edge 42. ing.

The inner heel circumference portion is housed in the upper part 14 in a sheath shape between the inner and outer layers 14b and 14a.

The interlaminar enclosure is a relatively rigid element formed from compressed fiberboard or leather similar to the material of the midsole 18. The medial interlaminar surround forms an upright flange from the underlying valley mass that extends below the periphery of the heel area of the midsole 18. The inner 1111 heel circumference part has an upper edge part 52 having the maximum height in the interlayer part which curves behind the heel area of the shoe 10, and the upper edge part of the m circumference part has a smooth arcuate slope. and slopes forward and downward to terminate at or slightly rearward at the leading end 40 of the interlaminar enclosure support.

(Effect of the invention) When assembling, the upper lip of the shoe, the heel area, the inner interlayer surrounding valley, and the inner interlayer surrounding valley are formed by the interlayer surrounding support field along with the intermediate sole 18. It nestles down inside the pot-shaped pocket and lies beneath the interlayer enclosure support edge 42. The interlaminar surround support phantom itself acts as an outer line surround to stabilize the shoe and the wearer's foot when running.

Additionally, the interlaminar surround support strengthens the other outer and medial line surrounds to prevent these interlaminar 8 sections from breaking apart from the sole of the shoe. As the shoe 10 flexes, the flexing of the sole places rearward forces on the upper 14 such that: 1. l-
In the direction of arrow “A” shown in Figure 6, the outer sole 1
Acts across the inner two surfaces of 2. Excluding the area around the line,
Thus, in a shoe with a flexing heel, the bending and tension of the material between the upper and outer sole absorbs this rearward force.

In a shoe with a linear perimeter, the verticality of the top of this area does not allow enough material to bend to absorb this force.

Shoes with relatively stiff outer soles, such as those with fixed nails, compromise this problem by allowing little or no bending between the line perimeter and the outer sole. Although not initially a problem, continued wear and bending of the shoe may cause the seam between the sole and the periphery to sever or cause the periphery to slide over the medial surface of the outer sole. To separate. This separation problem is worse in shoes with hard outer soles that are simply glued to the rest of the shoe than in shoes sewn together.

Adding to the problem of cutting and separation, the deflected rearward force causes the wire circumference to soften at its base due to the tension and absorption of this rearward force. As the line periphery softens at the base, the line periphery begins to collapse slightly into the lower blade, reducing the stability of the shoe.

The upper part of the pile 14, which occupies a seat in the bowl-shaped interlayer surrounding part support part, and the line surrounding part N and Sae, so that the rear force of the interlayer surrounding part supports the upper part of the pile and prevents it from pulling or sliding by cutting off the outer sole 12. Forms a relatively rigid vertical stop.

Because the interlaminar support is not separable from the outer sole 12, the interlaminar support prevents separation or cutting along the seam between the outer sole 12 and the upper 14, while at the same time preventing the interlaminar support from softening at its base. It also prevents destruction.

A similar problem of breakage and breakage is alleviated by the fact that the person wearing the shoe is lying down. People who lie down too much first strike the lateral side of their heel against the ground, then give the rest of the sole a lateral sway. Similar to the rearward forces created in a shoe by a person's walking, side-to-side compensatory rocking also creates bending and lateral forces in the sole. The force of fishing is from -111 of the shoe as indicated by the arrow rBJ in Figure 5, rather than from the front to the back of the shoe.
Directed from one side to the other.

This force of force likewise acts to cause a break in the seam between the line periphery and the sole, as well as to cause the line periphery to break along its base. The intermediate lateral forward-extending flange of the interstory support provides a relatively rigid vertical stop that prevents lateral separation and failure of the line perimeter adjacent to the pile top. In this way, the circumferential support 2o not only stabilizes the shoe during use, but also prolongs the life of the shoe.

It will be appreciated by those skilled in the art that many variations or modifications may be made to the preferred embodiments described above without departing from the spirit of the invention disclosed herein. Accordingly, the scope of protection afforded should be determined by the scope of the following claims and the breadth of interpretation permitted by law.
