Definitions

  • the invention relates to a structure for the flexible damping of dynamic effects on a body, especially a shoe-sole structure, mainly for sporting shoes.
  • the subject of the invention is also a damping member that can be used for such structures.
  • the task to be solved with the invention is to provide a structure that can be used for the flexible damping of dynamic effects on a body in the most general sense of the word, which structure ensures damping more efficient than the presently known similar structures, and also technically it can be realised in a simple way and is reasonable from the aspect of economy.
  • the task to be solved with the invention is also to provide a shoe-sole structure, especially sporting shoe-sole structure that provides maximum protection of the ankle, knee and hip joints of the person wearing sporting shoes with soles of this type, by approaching the bio-mechanical operation of bear soles.
  • the task to be solved with the invention is also to provide a damping member that can be used as a part of such structures.
  • the invention is based on the following recognition: for example when after jumping up bare soles touch the ground again, in the first moments the skin surfaces gets in contact with the ground. AS compared to each other the ground and the skin surface do not move, but a soft part of about 4-8 mm-s of the bare feet get deformed, and activated by this it forms a soft flexibility zone when hitting the ground. Whatever type of movements people make - e.g.: stepping, jumping, turning - only a certain part of their soles touch the floor or the ground, which part folds and undergoes soft deformation when it touches the ground. At this point the stabilisation of the feet is started, and in the second phase the harder flexibility and appropriate stability is provided by the ligamentous and muscular apparatus. In the first phase the dynamic effect is small and the deformation - movement - is large, while in the second phase the dynamic effect is large and deformation/movement is small.
  • an optimal shoe-sole structure should contain a folding/flexible zone that first ensures softer flexibility allowing relatively larger deformation on the given sole-part, and then harder flexibility allowing smaller deformation.
  • the shoe- sole structure should operate similarly to the bare sole - edge of the sole - when touching the ground.
  • the bio-mechanical operation of the feet changes when touching the ground: the material of the edges of the shoes, the construction and flexibility of the shoe-soles influence the operation of the feet, the legs and the joints.
  • the set task was solved with a structure, especially shoe-sole structure for the flexible damping of dynamic effects on a body, which structure has layers situated transversally with respect to the direction of the dynamic effect, connected to each other with flexible connecting elements, situated at a distance from each other in an unloaded condition, and which structure is characterised by that one end of the connecting elements is caught in the cavity created in at least one of the layers, and the internal space of the cavity is larger than or the same as that of the connecting element extending into it, and the connecting elements are made of a material with a greater ability of flexible deformation than that of the material of the layers.
  • the other end of the connecting elements can be attached to the surface, for example flat surface, of the other layer.
  • this solution represents a connection between the layers that ensures two types of different flexibility occurring between the layers, for example shoe-sole parts, in two phases, and the movement of the layers with respect to each other in space - that is in all directions - in the case that dynamic effect occurs.
  • the gap between the layers is an air-gap, although the possibility is not excluded that the gap is filled with some compressible material or material suitable for deflection as a result of pressure, for example gel, or with some other plastic, soft material, or with gas other than air.
  • some compressible material or material suitable for deflection for example gel, or with some other plastic, soft material, or with gas other than air.
  • the connecting element and/or the cavity accommodating it has the shape of a truncated cone, although other, practically optional shapes can also be chosen, for example with a circular, oval or polygonal cross-section.
  • the connecting elements can be solid or hollow, which provides the possibility of changing the time and/or extent of compression and the movement of the layers to suit the current field of use of the structure.
  • the connecting element starts from an upper layer and extends downwards, into a cavity created in a lower layer.
  • the connecting element can also start from the flat surface of a lower layer and fit into the cavity of an upper layer facing downwards.
  • both ends of the connecting element fit into a cavity respectively, created in layers facing each other. It may also be practical, if one or more intermediate layers are inserted between an upper layer and a lower layer, which intermediate layers are connected to the upper layer and the lower layer with a connecting element extending into a cavity, at a certain distance from them.
  • the layers are parallel to each other; and if the surface of the layers and/or connecting elements is smooth and/or coarse, and/or grooved and/or wavy and/or arched; and if the connecting elements are attached to the layers connected to them by gluing.
  • a further important feature of the invention is that only the end-plate of the connecting elements fitting into the cavity is fixed to the bottom-plate of the cavity, because in this way the connection element has the maximum freedom of lateral movement inside the cavity.
  • the materials of the layers connected by the connecting elements that can be flexibly deformed to a smaller extent than above can have different flexibility; for example in the case of shoe-soles the upper layer is made of polyethylene, the connecting element is made of rubber, for example latex, and favourably the lower layer is made of crepe fabric.
  • the connecting element is made of rubber, for example latex
  • the lower layer is made of crepe fabric.
  • other type of materials and combinations of materials, artificial and natural rubbers, plastics, etc. can also be used, and mostly the lower layer is made of a less flexible material, and obviously both layers are harder and less flexible than the connecting elements.
  • the invention also relates to a damping member used for the structure for the flexible damping of dynamic effects on a body, which damping member has a flexibly deformable connecting element situated between practically parallel layers situated at a distance from each other transversally with respect to the direction of the dynamic effect, and is characterised by that one end of the connecting element is caught in a cavity created at least in one of the layers, and the internal space of the cavity is larger than or the same as that of the connecting element extending into it; and the connecting element is made of a material with a greater ability of flexible deformation than that of the material of the layers.
  • FIG. 1 shows the upper layer of the sporting shoe with a sole structure according to the invention in perspective bottom view;
  • figure 9b is the top view of the lower layer to be connected to the upper layer as in figure 9a;
  • figure 9c is the bottom view
  • Figure Ia shows the first phase of the process demonstrated by figures Ia-Ic, and in this first phase a jumping or running person touches the floor 6, e.g.: flat ground, 6 with the front part - edge - of the sole 4 of his/her foot, as a result of which the soft part 5 of the solve 4 of about 4-8 mm-s gets activated, softly deformed, folded and flattened in a way that the skin surface of the sole 4 and the surface of the floor 6 do not move with respect to each other. By this the stabilisation of the leg starts, and it can be regarded as the first phase of softer flexibility.
  • Figure Ib shows an intermediate phase of the deformation process.
  • figure Ic which can be regarded as the second phase of harder flexibility, in which the ligamentous and muscular apparatus of the joints receives appropriate stability.
  • Figure Id shows that the foot touching the floor at an angle and the leg remain positioned along the same line in each phase, the straight line does not break where the foot and the leg join each other.
  • Figures 2a-2d show a process corresponding to the phases shown in figures Ia- Id, but in this case there is a traditional shoe 7 - sporting shoe - on the foot. It can be seen in figures 2a-2d that the shoe 7 changes the behaviour - bio-mechanism - of the foot when touching the floor 6, as a result of which the joints and the foot are not exposed to the stress shown in figure Id basically occurring in the direction of the axis of the leg, but this stress-line breaks in the region where the foot and the leg join each other, as shown in figure 2d; the problem caused by the changed bio- mechanism resulting in a risk of injury is also shown in figures 2a-2c.
  • FIG. 3 shows a part of the sole according to the invention, namely one of its basic damping members 8 the multitude of which comprises the sole structure itself.
  • the upper layer 9 of the sole, the lower layer 10 and the connecting element 11 joining them form parts of the damping member 8.
  • the damping member 8 is shown with a part of the lower layer 10 removed, the connecting element 11 of the damping member 8 has the shape of a truncated cone the cross-section of which reduces downwards.
  • the connecting element 11 is attached to the lower surface of the upper layer 9 at its upper plate not shown here, and it extends into the cavity 19 created in the lower layer 10 ending on its upper surface 20, which has the shape of a truncated cone narrowing downwards.
  • the lower plate of the damping member 8 is attached to the lower flat surface 21 of the cavity 19. Between the upper layer 9 and the lower layer 10 there is a gap 18 of a width, and it can also be seen in figure 3 that the internal space of the cavity 19 is larger than or minimum the same size as the internal space of the connecting element 11. Practically the lower and upper flat plate of the connecting element 11 should be fixed to the internal surface of the layers 9, 10 for example by gluing, as a result of which connection is created between the latter layers.
  • the material of the connecting element 11 is chosen in a way that its flexible deformability is greater than that of the layers 9, 10, that is it is softer than the less flexible material of the layers 9, 10.
  • the lower layer 10 can also be less flexible, harder than the upper layer 9.
  • the material of the upper layer 9 can be polyethylene - PUR or EVA; the connecting element 11 may be made of rubber (latex); and the material of the lower layer 10 touching the floor can be crepe fabric.
  • FIGS 5a-5e the layers are also marked with reference number 9 and 10, and between them there is always a gap 18, and in each case a connecting element 11 extends into the lower layer 10, and the material of the connecting element 11 is different from the material of the layers 9, 10, and the layers 9, 10 also have a different material from each other; it is shown by shading them differently and by dotting the connecting elements 11 the lower and upper surfaces of which are fixed to the internal surface of the layers 9, 10 by gluing.
  • Figures 5a-5e show that there are innumerable possibilities of creating the damping member 8, by choosing different materials, geometrical shapes and layer positions.
  • Figures 6-8 at an increased scale show - only as an example - that geometrical versions the connecting element 8 can also have structural versions, which are also included in the scope of protection of the invention.

  • the damping member 8 shown in figure 7 contains an intermediate layer
  • a second cone-shaped connecting element l ib starts from and is attached to the internal surface of the lower layer 10, and it fits into and is fixed into a cone-shaped nest 14 cut into the lower surface of the intermediate layer 13.
  • the cavities 12, 14 and the connecting elements 11a, l ib have a common x geometrical axis.
  • the damping member 8 shown in figure 8 is similar to the one in shown in figure 6, because cone-shaped cavities 19, 12 facing inwards are cut into both layers 9 and 10, and cone-shaped connecting elements 11a, l ib fixed to an intermediate layer 15, extending downwards and upwards from it are fixed into the cavities 19, 12 for example by gluing.
  • the connecting elements 11, 11a and l ib are also made of a material with greater flexible deformability - from a softer flexible material - like the layers 9, 10, 13 and 15. They - similarly to the connecting elements 8 in figures 5a-5d - should always be used to suit the current task to be solved. It must be pointed out here that the dimensions in the figures are not right, the figures serve the purpose of explaining the invention.
  • Figure 9a shows the upper layer 9 of a structure according to the invention for the damping of dynamic effects on the foot when touching the ground, which upper layer 9 forms a part of the sole of a shoe 7.

  • Figures 10c and 1Od are schematic geometrical drawings showing only the process of the deformation of the cavity 19 and the connecting element 11 fitting into it caused by dynamic effects gi, p_ indicated by arrows.
  • the first phase of flexible deformation - "soft" deformation - starts in the phase shown in figure 10c, as a result of which the connecting element 11 is gradually pressed into the cavity 19 - becomes activated - and in accordance with the direction of the p_ ⁇ force it also moves to the right, which also results in the slight movement of the sole layers in space with respect to each other.
  • the connecting element 11 in initial position the connecting element 11 extends out from the cavity 19 at a distance a.
  • the first phase ends and the second phase of "harder" flexibility independent from the first phase takes place, in the course of which the harder lower and upper layers (figures 3-8) start to operate. So it is obvious that in the first phase the sole structure gets folded even in the case of a small amount of dynamic effect, and it gets softly deformed to a relatively large extent, and in the second phase it ensures the final harder flexibility, the appropriate stability. In this phase there is great dynamic effect and small deformation or movement.
  • the invention has the following favourable effects:
  • the greatest advantage of the invention is that as a result of the operation of the shoe-sole structure described above the foot wearing the shoe behaves like a bare foot when touching the floor, such as ground surface, and in the angle, knee and hip joints are also strained in this way - basically similar to natural straining -, that is the natural bio-mechanical behaviour of the foot wearing the shoe corresponds to the same behaviour of the bare foot, for example in the course of making sporting movements there is a minimal risk of injuries.
  • This circumstance is demonstrated by the comparative curves shown in figures 1 Ia-I Ic showing the behaviour of the sole structure according to the invention as a function of the force (P) and the movement (E).
  • Curve m in figure 11a shows the behaviour of the bare foot
  • curve Hn figure l ib shows the behaviour of a soft sole based on the theoretical supposition that the complete width of the shoe-sole is made of the material of the connecting elements according to the invention.
  • curve k in figure lie shows the behaviour of a sole the complete width of which is made of a hard material.
  • curve m shows the ideal behaviour of the sole; in the case of curve 1 the movement is too large even in the case of small dynamic effect, while in the case of curve k there is slight movement even in the case of great dynamic effect.
  • Shoe-soles characterised either by curve 1 or k do not satisfy requirements expected from sporting shoes.
  • the invention ensures two types of alternating flexibility occurring in two phases independently from each other inside the shoe-sole, as well as slight possibilities of movement in space and folding between the sole layers and sole parts similar to that of the bare sole surface, which sole layers and sole parts can ensure different flexibility and ability of movement independently from each other.
  • the sizes and material qualities of all parts of the damping members can be changed, as a result of which the optimal flexibility behaviour and movement ability of a given sole part or sole surface can be ensured, and the most different demands can be satisfied.
  • By changing the width of the gaps the movement of the layers can be influenced as well as the direction and extent of movements.
  • a structure for example shoe-sole structure, can be created in which two - or more - different and independent flexibility conditions occur as a result of dynamic effects, namely softer flexibility with the possibility of large deformation/movement in the first phase and final harder flexibility and appropriate stability in the second phase, because of the compression and layer movement occurring in the first phase, after the air-gaps have been closed.
  • the invention is not restricted to the construction examples of the structure and damping member described above, but it can be realised in several ways within the scope of protection defined by the claims.
  • the structure and the damping member can be used to solve all tasks where the damping of dynamic effects is needed.
  • the foundation and construction of machines generating vibrations and oscillations during operation is emphasised, in the case of which these movements can be damped very efficiently by installing the structure according to the invention, but it can also be used in the course of making the foundations of buildings exposed to the risk of earthquakes.

Abstract

L'invention concerne une structure, et plus précisément une structure de semelle de chaussure, permettant d'amortir de façon flexible les effets dynamiques sur un corps. Cette structure comprend plusieurs couches (9, 10) disposées de manière transversale par rapport à la direction de l'effet dynamique, reliées entre elles par des éléments de liaison flexibles (11). Lorsqu'aucune charge n'est appliquée, les couches (9, 10) sont à une certaine distances les unes des autres. La structure se caractérise par le fait qu'une extrémité des éléments de liaison (11) vient se loger dans une cavité (19) formée dans au moins une desdites couches (10), par le fait que le volume intérieur de cette cavité (19) est supérieur ou égal à celui de l'élément de liaison (11) qui s'étend à l'intérieur de la cavité (19), et également par le fait que l'élément de liaison (11) est constitué d'un matériau possédant une capacité de déformation flexible supérieure à celle du matériau utilisé pour la fabrication des couches (9, 10). L'invention concerne également un élément amortisseur.
