System of cushioning for shoes
A43B7/32 - Footwear with shock-absorbing means (resilient soles A43B0013180000)
A43B21/26 - Resilient heels
A43B13/18 - Resilient soles
A43B13/12 - Soles with several layers of different materials
SUBSTANCE: shoes include a shoe upper, which is fixed to external parts of a sole, comprising an upper end part and a lower end part. The external parts of the sole have at least two support elements (41, 42, 43) at the heel level made of a cushioning material and arranged accordingly at the side edge and at the middle edge of the shoe sole. Each element (41, 42, 43) stretches in vertical direction substantially from the end upper part to substantially the lower end part of the sole. The support elements (41, 42, 43) are made with the possibility of deformation substantially independently on each other. The external parts of the sole also comprise an elastically deformed element (30). The latter includes the upper part, which stretches in transverse direction of the sole and covers the upper end of each support element (41, 42, 43), and at least two grips (34, 35, 36). Grips stretch at the side and in the middle of the sole and cover each support element from the outside (41, 42, 43) substantially along their full height.
EFFECT: provision of shoe sole cushioning along three different directions, simultaneously in horizontal plane and in vertical direction.
The present invention relates to a shock absorbing system for a Shoe, in particular sports Shoe for walking, Jogging, etc.There is a huge number of systems depreciation for sports shoes, and these systems are designed to absorb the reaction force supporting surface when walking, running or other movement.Typically, such devices amortization are designed to amortize the efforts of the counter, which are essentially perpendicular to the supporting surface, that is mainly in the vertical direction. Indeed, the efforts of the counter-acting in this direction, generally considered the greatest. These vertical forces counter buffer mainly due to the simple block of Styrofoam, as a rule, EVA, deformable in the vertical direction. Provided other ways of using pockets filled with fluid medium or gas.Recently he developed an interest in the efforts of the counter-support surface, the current is not in the vertical direction and in the plane of the supporting surface, hereinafter referred to the horizontal plane.Depending on the sport, horizontal forces will be more or less significant. For example, in sports such as tennis or basketball, where the larger part of the movement is sideways, reaction force acting at the level of the plane of the support surface, can be very significant.It was also found that the strength of the horizontal counter, which act during Jogging on asphalt, more significant, since the high friction coefficient of the material (asphalt) excludes any horizontal movement of the foot relative to the support surface that does not occur while running on softer ground, where may be the offset of the sole relative to the reference surface.The result was a new design shoes, in which device the depreciation soles provide a certain offset of the sole relative to the support surface and/or tangential displacement (mouvements de cisaillement) within the base, resulting in the absorption of forces acting essentially in the horizontal plane, and are reproduced efforts Jogging on soft ground.Such constructions are known, for example, from the publications US 6487796, US 5343639, EP 1402795 and US 5224810. These documents are based in General on the fact that depreciation is carried out only in the horizontal plane.In the publication WO 98/07343 disclosed a construction in which the elements in the form of pockets filled with fluid medium, can be deformed in three directions, i.e. in the horizontal pleskot is, as well as in the vertical direction.The disadvantage of this design is that the deformation in any direction are uniform, which does not allow to differentiate/separate depreciation in the vertical direction from the depreciation in the horizontal direction.Another problem that arises when designing devices amortization, is how to reconcile cushioning with stability/traction foot on the ground, whose functions are more or less incompatible.The task of the invention is to eliminate the above disadvantages and to provide improved device of depreciation.The task, in particular, is to provide a device of depreciation in three different directions simultaneously in a horizontal plane and in the vertical direction.Another objective of the present invention is to provide a device of depreciation that is compatible with good grip and/or track resistance".This problem or these problems are solved by developing a Shoe according to the invention, including the top of the Shoe, which is attached to the outer part of the sole, while the latter is provided at the level of the heel at least two of the support element of shock absorbing material located respectively with Bo the new region and the middle region of the sole, each item placed in the vertical direction essentially from the upper end portion to the lower outer part of the sole, the supporting elements made with the possibility of deformation essentially independently from each other, and the outer part of the sole contain elastically deformable element includes an upper portion which is placed in the transverse direction of the sole and covers the upper end of each of the support elements, and at least two tabs that are on the side and in the middle and cover the outside of each of the supporting elements essentially along their entire height.This design provides cushioning in all directions and ensures good stability and grip of the shoes.Indeed, in the case of essentially vertically directed load supporting elements are compressed and absorb the produced thus energy. Due to their independence and, in particular, due to the fact that the supporting elements are not connected at their lower ends soles for casual shoes, as in the known devices, the supporting elements are separated from each other relative to the longitudinal axis of the Shoe and thereby increase the support base, which increases the stability of the shoes.The invention is further explained in the description of non-restrictive examples, with reference to the figures, vchicle:

Fig and 17 depict views from the bottom of the sole according to eighth and ninth respectively variants of embodiment of the invention.Figure 1-6 shows the structure and functioning of the soles in the sports Shoe 1. Shows sports boot 1 is a Shoe for Jogging, but it may be sports shoes of any other type. This Shoe is shown in isometric view from below in figure 1. It includes the top 2 shoes, which is attached to the outer side of the sole 10. The top 2 shoes in further detail is not described, and shown in the figures only the outer part of the foot.Under the outer part of the sole 10 refers to the part of the foot located on the outside of the top 2 shoes; this outer part of the sole 10 does not include such portions of the outsole, internal shank, the effect of the insole, the insole Strobel, prostyle that are associated with the top 2 shoes and/or are located inside it. The top 2 shoes are fixed to the outer part of the sole 10 by any known method and in particular by gluing.As shown, particularly in figure 2 and 3, the outer part of the sole 10 include in the downward direction of the upper cushioning layer 20, the elastically deformable element 30, a few cushioning support elements 40 and the contact layer 50 (not shown in figure 2 for clarity).The upper cushioning layer 20 is essentially along the entire length of the soles of the 10, that is, from the rear end to the front end, and includes two parts, respectively, of the front 21 and rear 22 of essentially uniform thickness. The front part 21 has a greater thickness than the rear part 22, for example of the order of 4-15 mm Rear part 22 has a thickness of, for example, of the order of 3-10 mm In the present example, the front part 21 ends in the direction of the rear part in the form of a Chevron 23, forming the ledge relative to the rear part 22 whose function will be explained below. Instead Chevron 23 may be provided in any other form, such as wave, etc. of the Upper part 24 of the upper cushioning layer 20 is essentially flat or adapted to the shape of the Shoe upper. She may also have essentially vertical edges 25 extending along the top 2 shoes, in the rear area, in particular a heel, these edges 25 above, and the elastically deformable element 30 includes at the level of the heel portion in the form of a trough 31, that is, the part having a flat bottom 31A, taking the form of the upper cushioning layer 20 and includes edges 31b that extend along the top or edges 25 of the upper cushioning layer 20. In addition, some in the form of a trough 31 includes tabs 33, in this case two side legs, the middle two legs 35 and one hind leg, which interact with the support elements, as will be shown below. The number of pads can variovac the Xia depending on the desired result.
Each leg 34, 35, 36 extends from the rear of the trough 31 in a downward direction and ends with bending, respectively, 34a, 35A, 36A, which is placed between the shock-absorbing support elements 40 and the contact layer 50. These curves 34a, 35A, 36A are designed to ensure good bonding between the legs 34, 35, 36, and the contact layer 50, and the support elements 40. These curves, as an option, can be resolved.In the above example, the tabs 34, 35, 36 have a relatively flat shape, and the cross-section of the sole is slightly inclined shape of the letter V relative to the vertical direction (see figure 4), extending down to the end of the sole.In addition, as shown in figure 2 and 3, in the present example, these tabs 34, 35, 36 have an almost triangular shape, refining down. May also have other forms, depending on the function of the elastic element. For example, the tabs may have a wavy shape instead of flat, so that preference is given to the depreciation in the vertical direction. You can also provide that the tabs came only to part of the height of the blocks.Elastically deformable element 30 is extended in the forward direction due to the two flat legs 37, the operation of which will be explained below. The element 30 is made of a relatively hard and elastic material and has, in particular, the young's modulus of more than 40 MPa. the h may be made of synthetic or composite material, for example, TPU, PE, filled or unfilled polyamide, elastomeric polyester (Hytrel), PEBA, composite material based on carbon fiber/resin etc.Shock-absorbing top layer 20 is made of EVA foam or PU hardness over 20 Asker C.Reference damping elements 40 are formed by blocks of damping material located between the elastically deformable element 30 and the contact layer 50.In the first exemplary embodiment uses three independent support element, namely the average unit 41, located along the middle edge of the Shoe, and two side block 42, 43 located on the side. The average unit 41 has an arcuate shape following the contour of the Shoe sole, and runs essentially along the entire length of the zone of the heel. The average unit 41 communicates with the two middle legs 35 elastically deformable element 30. The most advanced forward side block 42 has essentially the shape of a parallelepiped and interacts only with one side leg 34 elastically deformable element 30. Most shifted in the rear side block 43 extends simultaneously on the side and on the back heel and interacts with two legs, respectively, of the side 34 and rear 36 elastically deformable element 30. The number of legs may vary for each block.This side block 43 that is has a shape of an arc of a circle, to fit the contour of the heel.In this embodiment, the side block 43 has essentially the same length as the average unit 41, but may have a different length, and the average unit 41 may be, for example, longer. Both side of the block 42, 43 are separated by a gap in the form of slits 46, essentially perpendicular to the edge of the sole, and the average and the side blocks, respectively, 41, 43, separated by a gap 47 in the form of slits, also essentially perpendicular to the edge contour of the sole in this area.Thrust blocks 41, 42, 43 are connected with the elastically deformable element independently from each other, respectively its upper end 41A, 42A, 43A. In the above example, the average unit 41 is extended towards the front of the Shoe, i.e. outside of the heel rounding, due to the cushioning layer 44 a lesser thickness, ending in the shape of a triangle or Chevron 44d, complementing the shape of the front part 21 of the upper cushioning layer 20, which provides a positive locking between the two layers. May also have other forms. The thickness of the layer 44 corresponds to the thickness of Chevron ledge 23. Almost blocks 41, 42, 43 made of elastomeric foam, EVA or PU foam hardness 20 Asker C. Such foams in fact differ as damping and elastic properties is AMI. In some cases, there may be provided more cushioning foams, such as elastomeric EVA foam. In the present example, the blocks have a thickness in the vertical direction from 10 to 30 mm and, for example, about 20 mmThe elements 30 and 40 pre-connected in the form of podborki 60, before connecting to the shock absorbing layer 20 to form the sole 10. The tabs 37 are placed in the notches 27 of the layer 20 to reinforce the connection.As shown in figure 2, each block 41, 42, 43 is equipped with one or two notches or cavities, respectively, 41p, 42s, and 43C, for receiving the respective legs 34, 35, 36 elastically deformable element 30. The notches have a complementary shape with the corresponding pads. According to a variant of execution of these notches could also be eliminated.Contact layer 50 is composed of elements, respectively, of the rear medium 51, the rear side 52, 53 and the front 54, which are fixed respectively on the lower ends 41b, 42b, 43b and 44b of the respective support blocks 41, 42, 43 and cushioning layers, respectively 44 and 21.Contact layer 50 is made of wear-resistant material having adhesion characteristics of materials such as rubber, TPU, EVA foam with high abrasion resistance, the latter two materials have less weight than rubber. In certain cases, and depending on the IP is althemore material for thrust blocks and/or a cushioning layer, a contact layer 50 can be reduced or eliminated.
Combining elastically deformable, but structurally rigid elastic element 30 with a shock-absorbing support blocks 40 can guarantee due to the independence of these shock-absorbing block 40 good cushioning in all directions, that is, three-dimensional cushioning, ensuring the stability of the whole structure due to the elastic element 30. In addition, due to differences in forms of blocks 41, 42, 43 and the number of/forms of pads on the respective block depreciation block can be allocated, first, between the individual blocks and, secondly, between the vertical and horizontal directions. The functioning of the whole structure is illustrated, in particular, figs.4-6.Figure 4 shows the soles 10 according to the invention in in-plane position on the support surface "S" and in the absence of any load. In this configuration, the support blocks 40, in particular, 41, 43, determine the reference basis of the "R"and length "l".When the load F is applied to the sole 10 is essentially in the vertical direction, the support blocks 40 are deformed, are removed from each other, loading the elastic element 30, and form a new, bigger support base, because the length "L" is greater than the length "l" of the previous base. In other words, the perimeter reference zone was large, and the resistance at the level of the sole factory is rather increased.
Once the load "F" is removed, the elastically deformable element 30 will exert a backward force and try to return the support blocks 40 in the initial position shown in figure 4. In practice, while running it is the supporting block 43 heel first subjected to a strain, as it first comes into contact with the supporting surface, then in accordance with the morphology of the user (pronator, supinator) in contact with the bearing surface shall be side block 42 or the average unit 41 and, finally, the opposite block, which causes, therefore, the spacing of the blocks 41, 42.Due to its independence thrust blocks 40 can be deformed independently from each other, adapting to the movement of the foot or to the configuration of the terrain. So, in the case shown at 6 and 6A, only the supporting block 43 and the corresponding leg 34 are deformed under load from cobblestone "P". Local deformation of the support block 43 is made possible in this case due also deformable independently of one another's feet elastically deformable element 30. Thus, the construction according to the invention is of particular interest for use on soft ground with a bump.7 to 9 illustrate a second variant implementation, in which similar or identical elements are denoted by the same positions, ovalicin the mi 100.
In this embodiment, the main difference is that a shock-absorbing support units 141, 142, 143 connects together cloth canvas (voile de matiere) 147. Because this fabric canvas has a small thickness, of the order of 3-10 mm compared with the control units 141, 142, 143, they are always free to move independently from one another. But the fact that they are so supportive of their connection.In addition, when the load F acts on the outer part of the sole 110 and the latter is deformed under the impact, as shown in Fig.9, fabric canvas 147 will be loaded by tension and, in turn, will also facilitate the return of the sole to its original form after removal of the load.To make possible this elastic return effect of the canvas 147, he is not glued to the elastic deformable element 130, and Vice versa, separated from it by the cavity 148.Another difference between the two versions of the implementation is that the shock-absorbing block 141, 142, 143, 144 forms a single unit.Finally, the average basic block 141 is made of a similar material as the rest of the kit 140, such as EVA foam, but greater hardness, for example, between 50 and 65 Asker C. He also extended into parts 144 through part 144A of the same hardness. It can be also made of other material, as the purpose of the this block 141 - to be a little firmer (less damping relative to other blocks). This function is also associated with type shoes (pronator or supinator).In the example implementation shown in figure 10 and 11, similar or equivalent elements are denoted by the same positions again increased by 100.In this case, a shock-absorbing support members 241, 242, 243 of the outer part of the sole is also collected in a single unit 240. Compared with the previous cases, where the element 40, 140 stopped shortly after plantar rounding, item 240 extends here to the zone metatarsophalangeal joint and, therefore, is longer.The thick part 221 cushioning layer 220, respectively, reduced and extends only from the front of the sole to the zone metatarsophalangeal joint (limited in this case, the ledge 223). In addition, the elastically deformable element 230 is in the direction of the front of the two elongated horizontal ledge 237 forming a kind of fork.Therefore, these elongated protrusions 237 extend all the way to zone metatarsophalangeal joint, delineated 223, 244d and allow additional elastic recovery of the sole in the front area. In addition, each of the protrusions 237 includes each foot 238, similar to the legs 234, 235, 236, and essentially vertically PR is erased along the front portion 244 of the support block 240.
The function of these vertical 238 feet as well as legs 234, 235, 236, is to provide enhanced stability of the soles.In the present case, the protrusions 237 and 238 feet of elastic deformable element 230 is placed in a corresponding recess e, 244f reference block, and these notches have complementary shapes and are made respectively on the upper side and lateral sides of the front portion 244 of the specified reference block 240.Fig-17 illustrate other embodiments of the invention, in which elements are denoted by the same positions, increased each time by 100.In these versions of the sole includes, as usual, at least two shock absorbing support element, but, in addition, provide additional funds return/stability.In the variant illustrated in Fig, sole 310 includes at least two independent damping support element 341, 343, outside covered essentially the entire height elastically deformable element 330 with soles for walking or contact layer 350.As in the variant according pig, the supporting elements 341, 343, remaining independent, connected fabric canvas 347 from the same material as the supporting elements 341, 343, allowing for ease of connection elements soles, and also achieves progi mutual return of supporting elements 341, 343, 342 (not visible in the drawing) after deformation.To increase the effect of elastic return, a contact layer 350, designed to connect various support units 341, 342, 343, which includes fabric canvas 355 connecting the various elements at their lower ends. Contact layer 350 made of a very elastic material such as rubber or any elastomeric material that provides the desired effect of returning the soles to its original position.This design gives the effect of added stability. In practice, this rubber canvas 355 eliminates up to 5 mm of residual variance between blocks after returning to the original position.In other words, it is possible to almost completely avoid any permanent deformation, which could lead to deviation between the blocks. In practice, it is possible to avoid permanent deformation of 5-8 mm, the length of the sole.Rubber (or made of other material) canvas 355 may be provided by itself, i.e. independently from the canvas 347.On Fig shows such an embodiment in which there is only rubber canvas 455.In this case, the gap 460 between the two support elements 441, 443, 442 (not shown in the drawing) is filled with material 461, such as EVA, PU, gel, which prevents the formation of holes in the rear for fabric canvas 455. This gap 460 may be compensated for by local elongation and low section of the material supporting elements 441, 442, 443, defined, for example, branches 355f, 355b, 355c on Fig (cf. below Fig, which is a view in section along the line XIII-XIII in Fig) or branches 355d, 355e on Fig.In an embodiment according Fig length 560 between the two support elements 541, 543, 542 (not shown in the drawing) is filled with material 561, such as EVA, PU, gel.At the same time between the elastically deformable element 530 and these support elements 541, 543, 542 provided by the cavity 548, in order to ensure the independence of these supporting elements, and between these elements there is a cloth canvas 547, made of the same material as the supporting elements 542, 543, 541.In an embodiment according Fig extending essentially horizontally elastic element return 647 placed in the same way as in the case depicted in Fig, between the support elements 641, 643, 642 (not shown in the drawing). The only difference is that the return element 647 in this case is made of another material, such as elastomeric rubber. In addition, this element is located essentially in the middle part in the vertical direction relative to the reference blocks.On Fig and 17 show various examples of implementation soles in Varian is E. according pig (and Fig and 14), that is, in the version in which the contact layer 350 includes a cloth canvas 355 between the two support blocks 341, 342, 343, providing elastic mutual return of these blocks relative to each other.In the case illustrated in Fig, fabric canvas 355 contains three substantially similar branches, respectively a, 355b, 355c, which extend from each of the corresponding reference block 342, 343, 341 and connected to form a star.In case pig fabric canvas 355 contains only two branches, respectively, 355d, e, each of which connects the two support blocks between them, namely, blocks 342, 341 and blocks 343, 341.Configuration Fig and 17 can also be applied in an embodiment according Fig, in which the return element 647 has the form of the three branches a, 355b, 355c or two branches between basic blocks.In different versions of the number of branches a, 355b, 355c or 355d, e can be changed and can be, for example, four or more or less.The proposed invention is not limited to described as non-limiting examples of variants of implementation, and includes all similar or equivalent options.1.
