The soles of sports shoes and sports shoes

 

(57) Abstract:

The proposed group of inventions relates to a sports Shoe and the soles containing at least one means of communication /10, 20/ sports product or projectile along the axis, strictly transverse relative to the longitudinal axis of this athletic Shoe, and means of communication includes means for anchoring fastening it in the sole, this means the anchor fixing /12, 22/ are arranged in a plane, generally perpendicular relative to the longitudinal axis of the /2/ the soles, and are independent from each other. In a preferred implementation of the invention, each means of communication /10, 20/ formed loop, which has a strictly U-shaped and which has a transverse branch /11, 21/, which defines the axis of the swivel, and two lateral branches /12, 22/, each side branch /12, 22/ fixed anchor way in a strictly vertical direction inside the soles. The invention allows for the possibility of bending of the sole at the great length on either side of each point anchor fastening elements compounds and to increase the overall flexibility of Elizabetta generally relates to the design of sports shoes, in particular athletic shoes for those sports that are associated with the slide, such as cross-country skiing or skating, and Cycling, in which the shoes must be attached in one way or another to the appropriate sports product, while maintaining the free spread of the foot in the course of employment by the relevant sport, and outside of these classes, for example during a normal walk in this athletic Shoe.

In the above-mentioned sports, in particular in cross-country or cross-country ski and have studied many ways of fastening the Shoe to the appropriate sport product.

So the traditional way of attaching a ski boot to the ski is flat races in the pressure of the boot to the ski by means of staples, interacting with the front protruding part of the base and clamping the part to the ski.

This method of fastening a ski boot prevents the full spread of the foot of the athlete, because his foot is fixed throughout its front. In order to eliminate this drawback have been proposed various systems swivel sports ski boot with a running ski relative to some of the anchor fixing this hinge axis in front of the ski boot, on the level of the hocks, with inserts and other techniques have been tested in practice with more or less success.

Essentially, the problem in this case is to find an acceptable compromise between numerous and quite contradictory requirements, namely:

- maximum spread athlete's foot, necessary to obtain the highest pulse or amplitude of the step depending on the particular sport;

optimal control and direction of body glide or sport products, which theoretically can be achieved only through the constant contact of the foot of the athlete with the body glide or sport product that by definition incompatible with the unfolding of the foot;

- strong enough anchor fixing inserts or the axis of the swivel at the bottom of the Shoe thus to eliminate the possibility of pulling out the hinge axis or insert in the course of employment by the relevant sport.

The above problem has been partially solved in the source FR 2739788, which discloses a system boot/device fastening a boot to a sports article, in which shoes soda is Edna Shoe parts, and the other is located exactly at the zone level metatarsophalangeal joint of the foot, and in which the mounting device is designed in such a way as to allow rotation of the Shoe around the first axis of the anchor pin and to provide exposure to a constant elastic recoil efforts on the second axis of the anchor fixing directed towards this sport product.

Thus, the existence of means of elastic return of the boot in the direction of a given sporting articles not located in the front part of this Shoe, as it takes place in the currently known devices of this type, but beyond the means of fastening the Shoe to the sporty product, ensures the control of the Shoe relative to the body of the slip, even when this Shoe is raised.

This shoes/fastening allows, therefore, to reconcile the problem of raising the legs and the control Shoe towards the sporty product, that, in principle, provides optimum conditions for maximizing the foot of the athlete.

However, this reversal of the foot, particularly in the final phase of rotation of wool or own extraordinary flexibility across its front.

This specific requirement is very high flexibility of the Shoe is hardly compatible with the need for a strong anchor fastening axes of rotation of this shoes or funds the sports product or the above-mentioned inserts fixed in this sports Shoe is exactly in the above mentioned area.

Indeed, technology anchor fixing various elements are known, for example, from sources FR 2533421, WO 88/05271 or FR 2645038, without exception, all involve the use of one or the other inserts, made either from a rigid plastic material or of metal, passing along a horizontal plane in the longitudinal direction of the sole of this athletic Shoe and accordingly increases the stiffness of the soles.

In the case described in US source 4872272 referred to the axis of the hinge connection formed by the transverse branch of the U-about-different loops, lateral branches which are also deep inside the sole of this athletic Shoe in its longitudinal direction and thus prevent any bending of this soles on the level of the lateral branches of this U-shaped and rigid loops. Mechanical tension is m, the softer is the material of the sole of the sports Shoe, and the more significant are the forces acting on the insert or the axis of rotation in the course of employment athlete this sport.

Thus, the task of the invention is to eliminate the above-noted deficiencies of the prior art in this field and to offer the design of the sole of a sports Shoe that provides the ability to save the greatest possible degree of flexibility of this soles on its front end with unconditional preservation opportunities strong enough anchor fixing it one or several axes of the hinged connection or other means of connection even when the sole of the sports Shoe is made from a relatively soft material.

This task in accordance with the invention is solved using the soles, which contains at least one means of cross connection with the sports product or projectile, with every means of communication includes means for anchoring fastening inside the soles, which are located mainly in sudestada, mainly along the vertical plane of this sports Shoe, but not in the horizontal plane of the Shoe that allows you to enable bending of the sole at the great length on either side of each point anchor fastening elements compounds and to increase the overall flexibility of the sole, without reducing the strength of the anchor fixing.

In the case when the design of the soles of this sport Shoe is provided the use of two or more means of connection, anchor fastening each of these means of communication are independent of each other, which guarantees the possibility of bending of the sole of this sport Shoe in the space between two adjacent means of communication.

Every means of communication defines the axis of hinge connections, each connection means is formed by a loop U-shaped, containing a transverse branch, the pivotal axis of the swivel, and two lateral branches, each side branch attached anchor image in the vertical direction inside the soles. Mainly each side branch contains a curved end that is oriented in a strictly g is assumed in the same vertical plane, that and the longitudinal axis of each of the side branch and each bent end, and a longitudinal axis transverse branches can be placed in a strictly vertical plane, which is offset in the longitudinal direction relative to the vertical plane containing the curved ends of the side branches.

At least one strictly transverse slit bending associated with each of the connecting means, and at least one slit of the bending takes place in the direction parallel to the direction of the metatarsophalangeal joint of the foot of the athlete.

Preferably the sole has a Central groove along its longitudinal axis, and every means of communication is located within this Central grooves, the Central groove is limited laterally by two cheeks, each anchor means anchoring drowned or submerged in each cheeks, and each slit of the bend passes over the entire width of each cheek.

Created sports shoes, containing the sole according to the invention.

Other features and advantages of the invention will be better understood from the following description of the example of its practical implementation, where reference is made to the drawings:

Thus, as is shown in more detail in Fig.1 and 2, the sole 1 according to the invention contains a guide groove 3 with gradually increasing in the direction towards the toe of the Shoe cross-section along the longitudinal axis 2 of this sole. In this guide groove has two connecting axes, respectively, of the front axle 10 and the rear axle 20, is fixed anchor way independently from each other. Of course, in this case, any shape of cross section of this guide groove 3.

The first connecting axis 10 is located exactly at the level of the front edge of the sole, while the second connecting axis 20 is located behind the first connecting axis and the area of the metatarsophalangeal joint of the foot of an athlete or a little in front of this joint.

The guide groove 3 is laterally limited by two jaws 4 rectangular cross section protruding downward from the base 5 of the sole, which also defines the bottom of the groove 3.

Special slit bending, respectively, 6 - 9, made in the cheeks 4 behind and/or in front of each of the connecting axis 10 and 20, the more the axis 10 and 20 are formed by the bracket, having a generally U-shaped and containing a transverse branch 11, 21 and two lateral branches 12, 22, held strictly perpendicular to the transverse branch 11, 21. Each side branch 12, 22 fixed anchor in one of the side cheeks 4 guide groove 3/, see Fig.3 and 6/.

Each transverse branch 11, 21 of the bracket is, thus, inside the guide groove 3 in the horizontal transverse direction, perpendicular to the longitudinal axis 2 of this sole.

In addition, each side branch 12, 22 of the bracket is held mainly in the vertical plane of the sole. As is particularly clearly shown in Fig.4 and 7, the longitudinal axis 11a, 21A of each lateral branches 11, 21 is located in the same vertical plane as the longitudinal axis, respectively 12A, 22A, lateral branches 12, 22.

Thus, means anchoring the fastening 12, 22 of each connecting axis 10, 20 are located mainly in the plane perpendicular relative to the longitudinal axis of the sole of this Shoe.

At the same time, each side branch 12, 22 of the bracket provided with end 13, 23, bent in the direction 13A, 23a, strictly horizontal and parallel lateral branches 11, 21 of each of the connecting means.

Thus, the connecting axis 21 and anchor fastening 22, 23 in the sole are located in the same vertical plane of this soles and have no extension in the longitudinal direction of the sole except for the actual thickness of this bracket. This method of anchoring fastening to a minimum reduces interaction with bending the soles.

In the case when the connecting axis indicated by item 11, that is, when we are talking about the axis on which the maximum extent affect connective efforts curved ends 13 are connected with the respective side branches 12 using strictly horizontal portion 14 along the longitudinal axis of the sole.

This design of the sole of the sport Shoe lets you optimize anchor fixation of the connecting elements, limiting to a minimum the extension or distribution in the longitudinal direction of the branches 12 - 14 of this coupling axis.

Thus, in both the above cases, it is still possible the ability of the sole to bend. This possibility Ishi 20 are fixed separately.

And finally, cracks bend 6 - 9 are associated respectively with each of the connecting axis 10 and 20 and also allow you to properly optimize conditions bend the soles.

The crack of the bend 6 is a transverse slit, located just behind the bent ends 13 of the branches of the anchor fixing axis 10.

Crack flexure 7 is a transverse slit precisely before connecting axle 20.

And finally slit the bend 8 and 9 are also strictly transverse slit located behind the said connecting axis 20.

At the same time, the slit 9 is made slightly inclined relative to the longitudinal axis 3 of the Shoe sole and located in the direction of precisely the corresponding axis of the metatarsophalangeal joint of the foot of the athlete.

In any case, the slit 6 - 9 pass from one side to the other across the width of the lateral cheeks 4 of this sole.

Thus, as it is easy to understand, sharing, connecting the axes 10, 20, secured in the base in generally vertical manner, and the transverse slots 6 - 9 ensures that the maximum bending of the sole of the sports Shoe.

inventions designed to allow anchoring of the fastening of the connecting elements in the thickness E of the soles are made from particularly flexible material, such as natural rubber or microporous rubber, and suitable for use any means of anchoring.

The connecting means 103 for reasons of cost minimization in a preferred embodiment, the implementation is straightforward. In the example presented here, the implementation of the connecting means has a circular cross section whose diameter is approximately 4 mm, However, this connecting means may have a different cross-section. As you can see in the above drawings, the ends of this connecting means includes a knurling or grooving 103A, designed to improve the anchoring of the fastening of this connecting means at the lateral edges 105 and 106 of sole 101 and the protrusion b. These parts hold is an additional means of fastening 111, generally having a U-shape. The installation of this additional fastening means on the connecting means 103-b is accomplished by deformation of the U-shaped bracket 111.

Made in FAV is Nisha least in its horizontal part, has a cross-section with dimensions l x e/, see Fig.9/, to ensure the implementation of two functions, namely the implementation due to the width l of a sufficiently large contact surface with the material of the sole 101, in order to get a sufficiently large mass a, 109b of this sole 101, and the provision due to its relatively small thickness e sufficiently small thickness E' of this sole, in which, however, can reliably secure the tool 111.

Thus, in this case, the sole 101, even made of fairly soft material and good fit for a normal walk, able to withstand significant mechanical stresses arising in connection with this athletic Shoe with the appropriate sporting equipment, and to provide strong binding communication means 103.

In a preferred embodiment, the implementation of the above-mentioned width l anchor means anchoring is fairly small, and this part of the fastening means is located approximately at or above the neutral line N of this sole, i.e. in the neutral zone or in the zone of compression when this bending of the sole, so that no satr iameter D communication means 103 so to allow installation on the desired location, and simple deduction system formed by the said means of communication and means anchoring the pin in the mold used for casting the sole, and to increase the contact surface and, consequently, to increase the strength of the anchor reinforcement.

In this sense, it should be noted the fact that in the case when the sole 101 must be poured on the top of the sports Shoe, already containing the first mounting element 112, the tool anchor fastening 111 may be previously registered in a preferred embodiment, the implementation of this first mounting means 112 by means of rivets or other equivalent means so that an even greater extent to improve the quality of anchor fastening.

In Fig.11 to 13 schematically shows a third possible way to implement a means of anchor fastening in accordance with the invention. This tool 211 is curved in the form of a "looped hook" in order to cover the ends b connecting means 203, and it is held in a vertical plane in the thickness of the soles 201 and ends with pads 211A, b. Pads 211A in palno short length of /about half the size of 1/ for in order not to impair significantly the flexibility of the sole 201. Paws b will be interconnected by means of a plate s thus, in order to form a single amenable to manipulation unit which can be easily positioned and held in the mold designed for casting under pressure of a sole 201.

This plate s in a preferred embodiment, the implementation will not have a longitudinal engagement at the top of the outsole with pads 211a. In this case, the size of X will be close to zero.

However, the sole 201 should be particularly well to bend at a distance FL, schematically illustrated in Fig. 11 and corresponding to the distance between the toes and the metatarsal joint. If the means of communication 203 is placed at the level of the anterior joint of the foot or back of the joint, sole flexibility becomes less effective behind this communication means 203 and the size of X may be more significant in order to control, for example, a kind of stimulation that bend the front part of the foot of the athlete.

In Fig.14 and 15 schematically shows a third possible way of implementation tools anchor fixing, paired with means of communication.

In this case, the tool SK from the bottom surface or the surface of the walk 308 of this sole.

Before filling in the sole 301 executes the casting on the ends of this means of communication parts 312 and 313, made in the preferred implementation of the same material as the sole of this Shoe, but with a higher elastic modulus and higher hardness.

Mentioned portion of reduced width l (see Fig.15/ in order to be compatible with a satisfactory longitudinal shibamoto soles 301 may in a preferred variant implementation to provide a corrugated or contoured surfaces 314, in order to improve the adhesion of these parts with the material in the soles.

As with other ways of implementing the invention described above, the goal in this case is to pass on a large enough surface mechanical stress from communications sports Shoe sports product or projectile and consequently to provide a satisfactory balance between the influence of the force and the surface exposed to pressure, which makes it acceptable mechanical stress applied to the sole of the sports Shoe 101, 201, 301, which of necessity is made of a material with a relatively small module eprouvette the ways of its practical realization, which were described above as examples. This invention covers all possible equivalent ways of its implementation, allowing to solve the problem.

For example, the means of communication may be different from a round rod.

The system formed by means of communication and means of anchor fastening at the base of this athletic Shoe can be based, in addition to latching or fill under pressure, as mentioned above, the sealing or beading, welding, etc.

Finally, the tool anchor fastening may consist of several separate parts with extensions or distribution in those areas, we have not been told, in order to provide additional effects or functions at the level of the operational behavior of the sole of the sports Shoe according to the invention.

It should also be noted that the above-mentioned vertical and horizontal directions are oriented relative to the longitudinal axis of the sole of the sports Shoe, which is horizontal.

The present invention is not limited to its application t the sports shoes, which should be solved the same or similar problem.

In particular, this invention can be applied to boots for the snow surfing or shoes for skating, which has a removable way to attach to the appropriate sports apparatus.
