MX2007011043A - Outsole with tangential deformation. - Google Patents

Abstract

The invention relates to an outsole (1), especially for sports shoes (2), that can be formed with a large amount of elastic deformability even in the tangential direction towards the front and the back, enabling a good cushioning effect even when the tread of the foot is inclined and somewhat slipping. Beyond at least one critical deformation in the deformed region, the sole remains however essentially rigid in relation to tangential deformation. In this way, the runner has a secure footing on the respective tread point. The runner can then push off from the tread point without losing ground. A swimming effect on the sole is thus prevented. According to the invention, the elastic deformability of the sole also in the tangential direction is caused by at least one first element (3a), and the cited rigidity of the sole in relation to tangential deformation beyond said at least one critical deformation, in addition to the degree of the at least one critical deformation in the deformed region is due to at least one second element (3b). So that said first and second elements (3a, 3b) can be independently designed, dimensioned and produced, there are extensive structuring, formation and variation possibilities. Certain areas in the heel and/or the ball region of the sole can be varied by the at least one first element (3a), and certain areas by the at least one second element (3b), in the longitudinal direction.

Description

OUTER SOLE WITH TANGENTIAL DEFORMATION DESCRIPTION TECHNICAL FIELD.

The present invention describes an outsole, specifically for sports shoes, deformable with elasticity both forward and backward in the tangential direction and which is only rigid with respect to the tangential deformation beyond a critical deformation in the region so far distorted.

The deformation in the tangential direction is here understood as a deformation, carried out, for example, by breaking in a direction tangential and / or parallel to the two dimensions of extension of the outsole or its passage. Deformations in the direction perpendicular to the two extension dimensions of the outsole or its pitch, caused, for example, by compression, should be differentiated from the foregoing. On a horizontal surface, the tangential directions coincide approximately with horizontal directions and the perpendicular directions with vertical directions.

STATE OF THE ART The elastically flexible outer soles are known in large numbers in different models, in which elastic materials of different hardness are used. Soles with cushioned air or gel padding are also known. These have the purpose of cushioning the tensions that occur when running and, in this way, protect the locomotor system of the runner, especially the joints and serve to give a pleasant sensation when running.

Most of the running sports shoes that are currently on the market, have features to perform jumps that allow cushioning mainly in the vertical direction or in the direction perpendicular to the step with compression of the sole, which is, however, relatively rigid in the horizontal and tangential directions and not flexible enough when the foot steps obliquely at an angle. The reason for this may be that a greater deformability of the sole in the horizontal direction would produce a kind of slip effect, which would have a negative effect on the stability and balance of the runner. The runner would also lose distance with each step, because the sole, when propelled from the point of impact, would partially deform in the opposite direction to that in which the foot treads. In a certain way, the sliding effect occurs, of course, in conventional sports shoes on the market. In order to avoid this effect, the frontal region of the sole of these athletic shoes, from where the impulse is usually made, is relatively hard and manufactured so as not to be flexible.

On the other hand, in spite of the pronounced tangential deformability, the mentioned type of soles, as also mentioned in the patent WO 03/102430, avoids the sliding effect beyond one or several critical deformations in the region deformed up to the moment , and said soles are essentially rigid with respect to tangential deformation. For the runner, after the critical deformation is reached, there is a safe position in the respective step or tension point, from which it can be pushed again without losing distance.

The patent WO 03/102430 describes several examples, through which the principle for the solution of the tangential deformability of the sole in conjunction with the rigidity beyond the critical deformation can be well understood. For example, hollow tube-shaped elements made of rubber are described, which, under perpendicular deformation, but especially also under tangential deformation, can be compressed completely forward and forward. backwards and then, due to the friction between their upper and lower intermediate bodies, they prevent a posterior tangential deformation.

Patent EP 1264556 discloses a sole for sports shoes, which has a softer outer layer and a harder inner layer. The projections on the harder inner layer penetrate the softer outer layer and protrude beyond the latter as supports. In this case, there is no tangential deformability of the sole and can also be prevented through the supports.

A sole, described in patent FR 2709929, has a similar construction, wherein the layer has sharp metal peaks.

UK patent 2285569 discloses a training shoe with a sole having first flexible elements and second rigid elements. The first elements are inclined at an angle towards the rear in the direction of the heel and collapse under the load in this direction between the second inflexible elements, which subsequently carries the load upwards. A corresponding deformation of the first elements towards the front is not possible due to the relative adjustment of the second elements.

Patent JP 5309001 discloses a shoe with a sole having an interior area of tangentially deformable projections in all directions and also having a cavity. This inner zone is surrounded by a zone on the shore with rigid low supports which, from a particular deformation of the following hollow projections, absorb the load.

The German utility model G 8126601 reveals a shoe with a sole, in which are inserted pieces with a brush shape with rigid bristles directed backwards. These bristles have the purpose of making possible a fast start forward, aiming the rear part, making a sliding towards in front. It does not have a corresponding deformation of the bristles towards the front and, quite possibly, it is not possible either. US 3,299,544 discloses a shoe with a sole, whose front region of the heel has transverse supports, which are directed backwards. In comparison with the supports, the area of the rear edge forms a kind of lower platform. Under normal running conditions, the supports have the purpose of making contact with the ground before that platform does, and at the same time, withdrawing towards the rear until the platform makes contact with the ground and limits subsequent deformations of the floors. supports.

DE 29818243 discloses a shoe mechanism with a sole, with elements inclined toward the back which, when the foot is treading, bend in the direction of the heel and make contact with the remainder of the sole.

Within the scope of practical applications of the known principle according to WO03 / 102430, as well as of the hollow tube-shaped elements described here, it has turned out that these can not be adjusted to all practical requirements, at least not in their specific form. described. It is no coincidence that, in the area of sports shoes, the special manufacture of such shoes, according to the requirements of the respective sport, is offered for almost any type of sport, especially the manufacture of soles that plays an important and even decisive role for their respective adaptation.

DESCRIPTION OF THE INVENTION.

The object of the present invention is to indicate how soles of the type known in WO 3/102430 can be better adapted, economically, to practical requirements, including the requirements of different sports.

According to the invention, this objective is achieved with the different characteristics contained in the claims.

The two functionalities that are required for the desired effect, that is, the tangential deformability on the one hand and the rigidity with respect to the tangential deformation beyond at least one critical deformation on the other hand, are linked according to the invention, with different elements. Due to the fact that the first element and the second element can be conceived, dimensioned and produced independently of one another, beyond the design, the possibilities of manufacture and variation arise in practice, with which the desired adaptation to the practical requirements it can be achieved in a better way than in the previous case with elements, such as the known hollow tubular elements, which simultaneously fulfill the mentioned functionalities.

Basically, in said patent JP 5309001 a corresponding division is also established in several first deformable elements and several second elements. The first and second elements are, in any way, arranged separately from each other. The first elements are in a first internal zone and the second elements in a delimiting zone around the internal zone. As a result of this, it can happen that the so-called internal foot or external foot corridors, to be dealt with in more detail later, will be developed exclusively on the hard elements located in the delimiting zone, or that, when working in the center of the sole, practically only the first elements are taut and there is a sliding effect, which is precisely what the present invention wishes to avoid.

Therefore, the invention ensures that, in the region of the heel and / or metatarsal in the sole, areas determined in part by a first element and partly by a second element, alternate repeatedly in a longitudinal direction (of the heel to the metatarsal region). By this means it is ensured that, when unscrewed on the heel and / or on the metatarsal region, both functionalities are always used in a temporal and spatial relationship sufficiently narrow between one and the other. The characteristics of the sole invented therefore correspond to a large extent to those of WO 03/102430.

You can count on several first elements. The zones, determined by at least one first element, can be formed by one or several said first elements. Correspondingly, several second elements may arise and the zones, determined by at least one second element, may in each case be formed by one or several of said second elements.

Like the soles described by WO 03/102430, the soles of the present invention can also be dimensioned so that the critical deformation, limited locally while running, is reached only in the most tense area and temporarily only in the maximum voltage point. Said critical deformation, in which the tangential deformability of the invented sole is, so to speak, frozen, depends on the type of deformation. It is also necessary that the deformation is not only tangential. A critical deformation can also be achieved in case of a complete perpendicular or vertical deformation.

According to a preferred development of the invention, the critical deformation is reached only after a plane of tangential and / or vertical deformation greater than 20% of the deformable thickness of the sole and, optionally, even greater than 50% of the deformation thickness of the sole is given. said thickness. Preferably, the tangential deformability should correspond even to approximately perpendicular deformability. In its entirety, this can amount to approximately 1cm.

For spring planes and cushioning, the invented sole effectively reduces the forces and tensions that arise when running. In particular, the invented sole behaves optimally cushioning when horizontal forces fall predominant, being able to flex gently in the direction in which it runs, for example, when breaking the step. For the running shoes that have soles from the state of the art, there is a strong tension stop, although these shoes have pronounced vertical damping, since there is practically no tangential deformability. During unfolding, the invented sole absorbs the predominant vertical forces through an equally good vertical deformation due to the damping action. In addition, it reacts in this phase also through different tangential deformations in different directions of movement between the foot and the floor, which usually manifest in a slippage of the foot in the shoe and which frequently leads to a friction with the socks or even to the formation of blisters. The shoe does not resist the movement that the foot wants to make with respect to the ground during the movement in which it unfolds. The shoe makes it possible to run without fatigue. During full load in the impulse phase, on the other hand, the invented sole loses its cushioning properties practically completely. In this phase, the damping is not required anymore and becomes only a hindrance to an effective impulse. In the impulse phase, the invented sole behaves as if it were "hard".

The pattern of soles that has been used for some time by different runners reveals great differences with respect to the predominant tension. This is due to the characteristics of the styles, which are different for each runner. Differences also arise in the distances traveled. For example, runners of short distances run predominantly on the front of the foot, only the metatarsal region being stressed. On the other hand, long distance runners rely predominantly on the heel and work on the entire foot. At this point a differentiation between the external foot runners and the internal foot runners is required. The external foot runners rest on the outside of the heel, working on the outer region of the middle foot and are also propelled on the outside of the metatarsal region or the region of the small toes of the foot. The situation is contrary for the runners standing internal. There are also mixed forms that, for example, are supported on the outside, working transversely on the middle foot and are driven in the region of the long toe and vice versa. The invented sole, being vertically deformable both tangentially and forward and backward, can adapt itself to these different tensions and be part of the natural movements of the foot.

APPLICATION OF THE INVENTION.

To begin with, an integration is described in Figure 1, which is not necessarily the optimal embodiment, however through this, the teachings of the invention can be well represented.

Figure 1 shows a running shoe 2, which is equipped with an invented sole 1. The sole 1 is formed by a number of first hollow elements of profile 3a, similar to those already known in WO 03/102430, as well as for several seconds platform-elements 3b. The hollow elements 3a may have a height of, for example, 15 mm and the platform elements 3b a height of, for example, 10 mm. The hollow elements 3a, as well as the second elements 3b can extend across the width of the running shoe 2. These can also be placed next to one another. The platform elements 3 can also enclose one or more hollow elements 3a in an annular manner. The elements 3a, 3b are attached (adhered, for example) to the lower face of an intermediate sole 4 of the running shoe 1.

The hollow elements 3a are prepared with a material that can be elastically deformed with the stresses that occur when running. The second elements 3b, as well as the intermediate sole 4 can also contain a certain elasticity; however, in comparison with the hollow elements 3a, they are essentially rigid, and especially rigid with respect to the tangential deformation. The hollow elements 3a are also higher, in contrast to the platform elements 3b, protruding below them.

Within the meaning of the definition set forth above, the hollow elements 3a in each case form "certain zones through the first element (s)". If several hollow elements 3a are placed next to each other, they can be pigeonholed together with said zone. The situation is similar for the platform elements 3b, which in each case form "certain zones through the second element (s)". As a result, the different zones alternate repeatedly in the metatarsal region as well as in the heel region in the longitudinal direction of the sole. If the second platform elements 3b enclose one or more hollow elements 3a in an annular manner, the different zones that are mixed additionally between one and the other, are placed on the surface of the sole.

If the running shoe 2 is manufactured as shown in Figure 1 b and by taking a taut step at an angle to the front as shown by the tension arrow P1, initially only the protruding hollow elements 3a will contact the ground 5 and they will deform vertically and horizontally with elastic amortization of the stresses. This deformation is limited to the second adjacent platform elements 3b as soon as the hollow elements 3a align with them at the same height. From this moment on, the second platform elements take the main portion of the tension and, due to their already mentioned higher rigidity, do not allow a minimum significant tangential mismatch in the running shoe with respect to the ground 5. In this phase , the user of the running shoe is standing safely and stably on the ground. In addition, as shown in Figure 1 in subsection c), the user can once again be propelled from the position of Figure 1 c) in order to perform the next step, without having to suffer at this point a loss of distance, since the second platform elements can practically not be horizontally deformed significantly in the direction of new tensions, indicated by the arrow P2 during the impulse.

In a detailed representation, Figure 2 shows one of the hollow elements 3a as well as the platform elements 3b of Figure 1 and, in addition, in the item a) in the relaxed state and, in item b), under a tangential tension. In section c), a deformation is shown, vertical or perpendicular downwards, from which it becomes clear that the advantages explained above with respect to stability and momentum without loss of distance are also achieved in the case of a voltage completely vertical.

For the sole previously described, the hollow elements 3a allow the desired elastic deformability, while the platform elements 3b, on the one hand, determine and limit the possible degree of deformation of the hollow elements 3a and, on the other hand, ensure the desired stiffness of the sole against the tangential deformation beyond the critical deformation. Since these two functionalities are distributed among different elements, there is a greater degree of configuration freedom with respect to these elements. For example, different materials can be used for the first and second elements. The hollow elements 3a also need to stop making fixed frictions according to the possible load as in the case mentioned in WO 03/102430 and, in general, they are significantly less taut. Above all, they do not need to support all the dynamic weight and the tension that is released thereon by the second elements 3b in a degree of noncritical deformation. It is advantageous if the surfaces of the second elements 3b, coming into contact with the ground, have a firm weight on the ground, which can be optionally stabilized by a special nature of these surfaces.

The hollow elements 3a can be characterized as "damping elements" and the platform elements 3b as support elements.

The embodiments explained above are distinguished by an extremely long deformation of the planes, which between the relaxed state, for example Figure 1a) and the state, for example, of Figure 1 b) can accumulate more than 20% and even more than 50% of the extension of hollow elements 3a on the platform elements 3b. The runner therefore floats "in the clouds" and, at no time, has a sense of lack of balance.

For the embodiments described above, the first and / or second elements 3a, 3b are subject to somewhat high loads, for example, due to tangential or breaking forces. If they are joined only with glue, the elements could, over long distances, be separated from the midsole 4. An improvement can be reached at this point, for example, by partially and optionally implementing the additional anchoring of the elements 3a and / or 3b in the midsole 4, as shown in Figure 3 for one of the elements 3a and two of the platform elements 3b.

Figure 4 shows an embodiment for which only the hollow element 3a shown is implemented in the midsole 4. On the other hand, the two elements 3b are manufactured in one piece with the midsole 4 e directly molded integrally this. In addition, the hollow element 3a is anchored in the midsole even by a dovetail connection.

A variation of the embodiment of Figure 4 is shown in Figure 5 and, in addition, in a relaxed state in part a) and in a state of tension in part b). The hollow elements 3a are implemented so deeply in the midsole 4, that the second protruding platform elements, like the elements 3b previously described, are no longer required and therefore are not formed. For this production, the "normal" surface 4.1 of the midsole 4 assumes the function of the second elements 3b previously described. In order for the hollow elements 3a to be deformed, the depressions 4.2 must be made wide and broad enough as also shown in Figure 5, that is, at an angle in the depression 4.2 in which they are located, until they are aligned with the surface 4.1 of the midsole.

In sections a) and b), Figure 6 shows later variations of the type mentioned in Figure 5, for which, the first elements 3a are relatively implemented deep in the midsole 4 and by which the "normal" surface 4.1 of the midsole 4 assumes the function of the elements 3b described above. The variations of Figure 6 differ only in the manufacture of the first elements 3a. On the left side of Figure 6, the relaxed state is shown in each case and, on the right side, the state of tension in the critical deformation phase.

For the manufacture of Figure 6a), the first element 3a that can be deformed, for example, at an angle or tangentially, is manufactured in the form of a pin. The cavity 4.2 can, for example, be manufactured around it. Around, the edge of the cavity corresponds to the distance of the pin 3a, which is located in the center of the cavity, as shown in the two detailed representations in the lower part of Figure 6a).

For the manufacture of Figure 6b), the deformable element 3a is manufactured in the form of a small tube, which is located on its axis perpendicular to the midsole 4. On the contrary, the manufacture and representation correspond to those of the Figure 6a).

In part a), Figure 7 shows a layer or layer 6 of an elastically deformable material, in which the first elements 6a and second elements 6b are alternately formed in a relaxed state. This layer 6 can be produced in one piece and as a long piece. The same sequence of the first elements 6a and the second elements 6b can be found perpendicular to the plane of the drawing, in such a way that a structure results for which each first element is surrounded by four second elements and vice versa. The first and second elements are therefore mixed with each other again, as already discussed. The pieces of this layer, cut according to the size, can be adhered, for example, to the lower face of the intermediate sole 4 of the running shoe 2 of Figure 1, as shown schematically in Figure 8 in part a).

The first elements 6a have the shape of truncated cones, they are hollow and they are a little higher than the elements 6b, which consist of a solid material and also have the shape of a truncated cone. Like the first elements 3a previously described, the first elements 6a are relatively smooth and can be deformed tangentially forward and backward as well as vertically. Due to their rotational symmetric shape, they can even be deformed tangentially in the same way in all directions, which will be additionally advantageous in relation to the desired unfolding behavior.

In contrast, the second elements 6b are essentially rigid and functionally correspond to the second elements 3b) previously described. The elements 6a and 6b can be smaller than the elements 3a and 3b. For example, the height h1 of the total layer 6 and with that of the first element 6a can be from 8 to 12mm and preferably 10mm while the height h2 of the second elements 6b can be from 4 to 8mm and preferably 6mm. The thickness of the layer 6 in the transition region between the first and second elements can be, for example, 2mm, however, the thickness of the bottom of the first elements 6a, will preferably be greater than 2mm. The horizontal distance between the centers of the first and second elements 6a, 6b can, for example, be 10 to 20 mm and preferably 15 mm.

In part b), Figure 7 shows the layers 6 loaded towards an angle in a floor 5. The first elements 6a are deformed vertically under this load especially, however, tangentially or horizontally without protruding from the second elements 6b. A further deformation of the first elements 6a is prevented with the second elements 6b. The distances of the first and second elements are preferably selected to have such a magnitude that the first elements 6a can reach the deformation shown. The extension of the plane of tangential deformation before it reaches the critical deformation is greater at this point than the possible plane of vertical deformation and, by the dimensions mentioned above, adds at least a total of 5 mm.

In part c), Figure 7 shows a layer 6 under a vertical load.

The elasticity of the first elements 6a must be selected in such a way that the critical deformation occurs in a load of approximately 1 kg to 10 kg. This value depends on the number of elements and their suitability on the surface of the sole (local density), the desired cushioning and the weight of the runner. With its weight (optionally dynamic), the runner must be able to perform the critical deformation when pushing. This is a reality for all possible embodiments of the invention and correspondingly also for the elements of the type of elements 3a. A different flexibility or different amount of the first 3a / 6a elements should be selected for small shoe sizes (a lighter weight runner) and also chosen for larger shoe sizes (a heavier weight runner). For the first elements of the type of element 3a, a number of 8 to 15 elements, distributed on the heel and the metatarsal region, is usually sufficient. Due to the smaller size, usually more than 20 elements of type 6a are required.

There is a latitude of later configuration with respect to the shape of the first elements 6a and second elements 6b of the layer 6 of Figure 7 and their relative adjustment to one another. For example, the second elements 6b can be manufactured perpendicularly to the plane of the scheme as elongated supports, regularly or irregularly in the form of platforms as shown in Figure 8 in items b) and c). The second elements 6b can even form a coherent surface, in which the first elements 6a are placed in an unordered manner, as shown in Figure 8 in part d).

From the figures shown in Figure 8, it is evident that the first elements 6a are placed mixed with the second elements 6b, implemented regularly between the second elements 6b and, thus, protected against excessive load with high wear. Along with each possible plane of unfolding, the first and second elements are also tightened in this way in each case in closed and temporary spatial sequences so that the behavior of the sole and the feeling when running are always determined by the two elements. The mixed distribution of the first and second elements extends over the entire metatarsal and heel region.

In the transition region between the heel and the metatarsal, the first and second elements are usually not required. Generally, it is therefore sufficient for the applications that the layers 6 are placed separately in each case only in the region of the metatarsal and the heel. A longitudinal division can also be made instead of or in addition to a transverse division with respect to the longitudinal direction of the shoe. A longitudinal and transverse division with four layers 6 is shown in Figure 8 in part c). By this means, the adaptation to different shoe sizes can be achieved with the standard elements, in which these fit especially closely together or widely separated from one another. Finally, different layers can be given with different properties in different regions.

The areas mentioned and determined either by one or more first elements or by one or more second elements, can be matched in the embodiments of Figure 8 with the first elements 6a and with the second elements 6b respectively. In the example of Figure 8b), the several first elements 6a, which are placed side by side in the transverse direction, can also be counted as a single area. On the contrary, the coherent surface 6b) in the example of Figure 8d) can be considered to be formed by several zones alternating the longitudinal direction with the first elements 6a or with the zones formed by these elements Further configurations of layers 6 are described below by means of Figure 9 of items a) through e).

For layer 6, shown in Figure 9 in part a), the first elements 6a) correspond to those of Figure 7. The second elements 6b have a rectangular cross section.

For the layer, shown in part b), the first elements 6a are made of a solid material; however, they have a thick head in a narrow neck and can then be deformed sideways, in all directions as well as tangentially.

For the embodiments shown in part c) and d), the first elements 6a are formed by dimensionally stable knots 6a which are connected on a type of deformable membrane 6a with the second elements 6b and thus can be deflected vertically and also horizontally therein. measure.

For the version shown in e), two elastic layers are connected to each other, at least the continuous and relatively flat outer layer with the exception of the cavities. The cavities, together with similar approximately opposite outputs, form the first elements 6a. The cavities, in addition, in the form of a buffer, enable the various first elements 6a simultaneously to be deformed tangentially in different directions. The second elements 6b are formed by an outer layer between the cavities and the platforms or supports below, as shown in Figure 9a).

Within the focus of the above specification, only some possible embodiments have been described by way of example. There are of course more possible embodiments and can result, in particular, from mixed forms of the described examples.
