Description

  The present invention relates to a shoe, in particular a sports shoe, having a shoe upper and a sole, wherein a cushioning element is arranged above or in the sole.

  In this type of sport shoe, which is generally known, it is necessary to provide the desired spring and cushioning behavior of the sole. For this purpose, several solutions are known in the prior art.

  WO01 / 17384A2 describes a sole for shoes, and in this case, a plurality of ribs having a curved shape between a support body or an inner portion and an outsole are positioned in a rear foot region. Yes. Therefore, the rib bends when the sole is loaded by an impact force. In this case, the rib has a substantially semi-elliptical shape.

  In this case, it is a disadvantage that, based on this deformation of the ribs, a relatively significant collapse of the spring stiffness can be observed, which leads to poor control of the spring stiffness and is not desired.

  The object of the present invention is to improve a shoe of the type mentioned at the outset, in particular a sports shoe, to give a better controllable course of the spring stiffness over the spring path, ie the deflection. Furthermore, it is desirable that the spring stiffness extends over the deflection based on the desired function, and it is not desirable to suffer collapse in a particularly continuous manner. Therefore, it is desirable to be able to favorably influence the spring behavior of the shoe sole or the cushioning element arranged in the shoe sole.

  The solution to this problem according to the invention is characterized in that the buffer element has a first group on the upper side of a plurality of buffer bodies formed in a substantially U-shape or tank shape in cross section, in which case the buffer body Each of which has two legs coupled to a coupling section, wherein the cushioning element is formed in a substantially U-shaped or tank-shaped cross section in a lower second group of cushioning bodies. In this case, the cushioning body has two legs respectively coupled to the coupling section, the cushioning element has an intervening support, and the intervening support is , Disposed between the two groups of the buffer body, and the leg is in contact with the intermediate support at the end of the leg spaced apart from the coupling section, or the intermediate support The legs are joined, in this case the upper side and Junction point of the side of the cushion is arranged on the intermediate support being offset in the longitudinal direction of the damping element.

  Advantageously, the joint of one shock absorber is arranged in the middle between the two joints of the other shock absorber as viewed in the longitudinal direction of the shock absorber element.

  That is, the idea of the present invention is to provide two different groups of buffers. Each of these groups is formed in a tank shape or a U shape in cross section, and is adjacent to each other at the junction. The tank-shaped or U-shaped bodies of the upper group and the lower group can be oriented to each other on their open side and are connected to each other via an intervening support.

  This provides a shock absorbing element with spring and shock absorbing characteristics that can be adjusted or exerted over a wide area.

  The refinement proposes that the intervening support is formed as a substantially flat and plate-like part. It should be further understood that under this, the intervening support can have a slightly corrugated course in the longitudinal direction of the buffer element.

  Further, the intervening support body continues to the extending portion of the sole, and in this case, gradually curves from the front foot region to the rear foot region through the intermediate foot region where a sufficiently flat shape exists. In other words, it is possible that it is not flat there. In the heel region, the intervening support can in particular be configured in a cup shape.

  Advantageously, for the case where the shock absorber is constructed as a tank-shaped molded body, the legs of the seal body extend straight and have an angle of 45 to 85 ° with respect to the plane or horizontal plane of the intervening support In contact with the intervening support. The spring behavior can be decisively influenced via the selected angle. The flatter the angle at which the leg reaches the intervening support, the higher the pressure at the leg that occurs when the shoe is loaded.

  The legs of the cushioning body and the coupling section can be molded as a part formed in the planar body. These portions extend over at least a portion of the width of the shoe to form a hollow chamber. According to the predetermined configuration, the leg portion and the coupling section of the buffer body extend over the entire width of the sole as a portion formed in the planar body. As an alternative to this, the legs of the shock absorber and the coupling section are formed as planar parts, extending only in the lateral area of the sole, and the area cut out in the central area. It is also possible to provide it.

  According to another configuration of the invention, the cushioning element extends from the heel end of the sole. A cushioning element can be arranged on the underside of the heel cup. Furthermore, it can be proposed that an outsole is arranged on the lower surface of the buffer element. An alternative arrangement for this proposes that the coupling section of the lower buffer is formed as a segmented outsole.

  In order to obtain a certain amount of spring and shock-absorbing characteristics also in the rear region of the shoe, the shock-absorbing element can extend to the rear end of the shoe and extend upwards around the heel. In this case, according to another refinement, the cushioning element extends to a height of 40 to 75% of the total shoe height in the heel region. As the end of the buffer element, the last leg of the tank-shaped or U-shaped buffer is recognized.

  The outsole may extend at least over the entire area where the cushioning element extends. It can also be proposed that the outsole extends beyond the area of the buffer element.

  Manufacturing technical advantages can be achieved if both groups are formed as an integral injection-molded member with the interposer together with the interposer.

  The sole part, in particular the buffer element, is preferably made of plastic, in particular thermoplastic material. Particular preference is given here to polyethylene, polypropylene, polybutane, polyamide, polyurethane, or a mixture of at least two of these plastics. The plastic may be translucent or transparent. The outer sole can also consist of plastic, preferably polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these plastics or rubber. In this case, the material is not translucent or transparent.

  The material and geometric dimensions of the individual components of the cushioning elements (legs, coupling sections, intervening supports) are selected by those skilled in the art to define the spring and / or cushioning characteristics of the cushioning elements be able to.

  The described arrangement provides spring stiffness based on a desired course over at least a predetermined spring path area. The spring stiffness, which is an absolute value, can be adjusted via the thickness of the components of the cushioning elements (legs, coupling sections, intervening supports). To that end, as already mentioned, the angle at which the leg leads to the intervening support can also be taken into account for design and adjustment.

  The production of the proposed shock-absorbing element and the entire shoe is possible in a simple manner and inexpensively, for which a known technique is used.

  In the shoe according to the invention, advantageously, both groups of the cushioning bodies are formed as an integral injection-molded member together with the intervening support.

  Embodiments of the invention will now be described with reference to the drawings.

  FIG. 1 shows a cushioning element 3 incorporated in a sports shoe. The integration into the shoe for a similar buffer element 3 is evident from FIG. Only the heel region is shown here. Of course, a similar configuration applies to the front foot area. The front foot region may likewise incorporate a buffer element according to the invention. In addition, it is possible to provide a single cushioning element 3, which extends over the entire length of the shoe.

  The buffer element 3 of FIG. 1 has two groups 4 and 9 of buffer bodies 5 or 10. The plurality of buffer bodies 5 or 10 are arranged side by side and are in contact with each other at the junction 15 or 16. The shock absorbers 5, 10 are formed in a tank shape in this embodiment, that is, each shock absorber 5, 10 has two legs 6, 7 or 11, which are connected to each other via a connecting section 8 or 13. 12. Therefore, the coupling section 8 or 13 and the two legs 6, 7 or 11, 12 form a buffer 5 or 10 and have a cross-sectional shape, ie a shape similar to a U-shape when viewed from the side. Yes.

  The upper group 4 of the buffer body 5 and the lower group 9 of the buffer body 10 are respectively joined to the intervening support body 14. In this case, the interposer support body 14 is sufficiently flat, but the buffer body 3. It can also have a slight waveform in the longitudinal direction L. That is, the joint portions 15 or 16 of the adjacent leg portions 6, 7, 11, 12 are coupled to the intervening support 14.

  As can be further seen, the joints 15 or 16 are offset from one another in the longitudinal direction L and are arranged relative to one another. The joint 15 of the upper shock absorber 5 is located between the two joints 16 of the lower shock absorber 10. This applies appropriately to the joints 16, which are each located between the two joints 15.

  This arrangement provides a shock-absorbing element with spring and shock-absorbing characteristics that can be defined particularly advantageously and reproducibly. In order to uniquely define the spring and shock-absorbing characteristics, the angle α can be taken into account in particular (see FIG. 1), and this angle α depends on how the legs 6, 7, 11, 12 are connected to the interposer support 14. Determine if you are in contact. The value for the angle is preferably between 50 and 80 °.

  It can be seen from FIG. 2 how this type of cushioning element 3 can be incorporated in the shoe together with the shoe upper 1 and the sole 2. The shock absorber 3 is not formed flat here (as in FIG. 1) and follows the course of the heel of the shoe support.

  Based on the stated height h, it can be seen that the cushioning element 3 extends upwards to a region corresponding to approximately half of the total shoe height H in the heel region.

  In the embodiment of FIG. 2, the cushioning element 3 is arranged on the underside of the heel cup 20, which heel cup 20 is adapted to the heel shape of the shoe support. An outsole 21 is disposed on the lower surface of the buffer body 3, and the outsole 21 covers the buffer element 3 from below.

  As can be seen from the cross-sectional view AB of FIG. 2 shown in FIG. 3, the cushioning element 3 does not extend over the entire width of the shoe in this embodiment. Rather, in order to keep the area cut out in the central area 19 open, the cushioning element 3 extends only in the two lateral areas 17, 18. Of course, this notch can be provided only in a part of the sole. In this case, the buffer element 3 is entirely provided in another area of the sole.

  The shock-absorbing element 3 is preferably formed from an integral injection-molded part (preferably EVA). In this case, the buffer element 3 can be glued to the heel cup 20 or the outsole 21 or can be inserted into the notch. These notches are provided in the sole 2 for this purpose.

  The improvement of the damping element 3 shown in FIG. 4 is based on the same inventive concept as the solution of FIG. In the above solution, the individual buffer bodies 5 and 10 of the two groups 4 and 9 are configured symmetrically with respect to the virtual center plane. This means that in the solution of FIG. For at least a portion of 10, this is not a problem. As is apparent based on the described angles α ′, α ″, it is asymmetric. The angle α ′ is slightly less than 90 °, and another angle α ″ is about 60 °. The angles α ′ and α ″ are angles at which the extending portions of the leg portions 6, 7 or 11, 12 stand with respect to the plane of the intervening support 14 or the virtual horizontal plane.

  Furthermore, it can be seen that the coupling section 8 or 13, in particular the upper coupling section 8, has only a very short extension when viewed in the longitudinal direction L of the shoe or cushion 3. In other words, here, the connecting sections 8, 13 are connecting points (or connecting lines extending over the width of the shoe). The legs 6, 7 or 11, 12 are connected to each other by this connecting point. As can be seen, the transition from one leg to the other leg can be formed as a rounded part. It can be seen that this rounded part is the joint section 8, 13 in this case.

  In this case as well, the buffer element 3 can be cut into a region near the bottom. This incision does not have to be forced to extend in the longitudinal direction L, i.e. it does not have to be machined in the form of longitudinal grooves. The incision can also have, for example, an elliptical or kidney-shaped profile when viewed from the bottom.

  The proposed damping element 3 can be arranged only in the rear foot area, i.e. below the heel. As an alternative or in addition, it can also be proposed that such a buffer element is arranged in the front foot region. It is also possible for the finally described cushioning element to extend over the entire shoe length.

It is a perspective view of a buffer element. It is a side view of the rear part of shoes. It is the figure which showed the cross section AB of FIG. FIG. 2 shows a similar configuration of the buffer element according to the invention, which is an alternative to FIG. 1.
