Definitions

• the invention relates to a sports shoe as described in the preamble of claim 1.
• EP 0 672 365 A2 discloses a ski boot with a sole part fastened to a shell made of at least one heel and a pointed part, in which a longitudinal stiffening fastened to the underside of the shell is arranged to increase the torsional rigidity for exact and good power transmission is. Due to the large-scale introduction of force of the alternating loads acting on the longitudinal stiffening in driving operation, directly in the
• the object of the invention is to provide a sports shoe, in particular a ski shoe, which has a high torsional stiffness and good with a material and thus weight-saving design
• This object of the invention is achieved by the features reproduced in the characterizing part of claim 1.
• the surprising advantage of a rib composite part formed in one piece from the shell wall and ribs with a profile element supporting this is that shock and vibration loads are damped and thus kept away from the user's foot and at the same time there is a high degree of lateral stability due to the resulting torsion-resistant composite. whereby the steering forces to be applied by the user's foot via the shoe to a sliding device are transmitted uniformly via the heel elements arranged in the toe and heel area of the sports shoe.
• this design shows that the specified mechanical and dynamic properties such as flexibility and bending behavior of a gliding device, in particular a ski, are not impaired when the sports shoe according to the invention is used, or that these properties which substantially determine the driving properties are promoted.
• An embodiment according to claim 7 is also possible, whereby a lateral covering of hollow chambers of the rib composite part and a lateral support of the shell base is achieved.
• the individual elements are positioned relative to one another and length compensation is possible in the longitudinal direction, with simultaneous transverse stability for a vibration-free transmission of
• designs according to claims 10 to 12 are also advantageous because, on the one hand, this ensures the dimensional relationships required for injection molding and, on the other hand, sufficient strength is achieved for the loads occurring with such a sports shoe with maximum damping properties.
• Figure 1 shows the sports shoe according to the invention in view.
• FIG. 2 the sports shoe in view II of Figure 1, partially cut.
• FIG. 3 shows the sports shoe, cut along lines III-III in FIG. 1.
• the ski boot 2 consists of a shell part 3, which is manufactured in particular by the plastic injection molding process and which is made, for example, from plastic materials that differ from one area according to the plastic injection technologies known from the prior art, in order to achieve the best possible adaptation of the material properties required for different areas of a shoe.
• the shell part 3 is provided with an entry opening 4, which is called overlap shoe can be closed by molded on the shell part 3 tabs 5 and corresponding closure elements 6, such as buckles 7.
• a pivotable sleeve part 8 is also articulated on the shell part 3.
• An inner shoe 10, which is surrounded by the shell part 3 and the sleeve part 8, is provided for receiving a foot 9.
• This rib composite part 13 is formed by a shell wall 14 and ribs 16 formed thereon on a surface 15 facing away from the support surface 12.
• one of the longitudinal ribs 18 runs in a longitudinal central plane 21 formed by a longitudinal central axis 20 and parallel to this in each case a further one at a distance 22 on both sides of the longitudinal central plane 21. These longitudinal ribs 18 are over the
• Transverse ribs 19 connected to the rib grid 17, a distance 23 of the transverse ribs from one another being greater than the distance 22 between the longitudinal ribs 18.
• a rib height 24 corresponds approximately to a thickness 25 of the shell wall 14, although the longitudinal rib 18 running along the longitudinal central plane 21 in Direction of a front end region 26 of the sports shoe 1 increases in height.
• the corresponding dimensioning of the ribs 16 and their arrangement on the surface 15 bring about an excellent shock and / or vibration-damping design of the rib composite part 13.
• the rib composite part 13 forms mounting surfaces 28 for the support of heel elements 29, which are fastened to the rib composite part 13 via tensioning and fastening arrangements 30 and form contact surfaces 31.
• the heel elements 29 are essentially assigned to a heel ball support area 32 and a forefoot support area 33 and form coupling extensions 34 with the protrusions protruding over the shell part 3, for example for a ski binding, board binding or similar hold-down devices.
• the contact surfaces 31 of the heel elements 29 are generally designed to be non-slip and are optionally provided with a wear-resistant layer 35.
• the clamping and fastening arrangements 30 are screw connections 38, according to which the shoulder elements 29 receive threaded screws in bores, for example countersunk screws 39, which, starting from the contact surface 31, project through the shoulder elements 29 and are screwed to threaded sleeves 40 anchored in the shell part 3.
• the threaded sleeves 40 are firmly connected to an anchor plate 41, which rests on the support surface 12 of the shell base 11, the threaded sleeves 40 projecting into recesses 42 in the rib composite part 13.
• the rib composite part 13 is shell-shaped in some areas and connected to it in a motion-proof manner a profile element 43, e.g. made of fiber-reinforced plastic.
• This profile element 43 extends between the tensioning and fastening arrangements 30 between the rib composite part 13 and the heel elements 29 and is also fastened in these areas with the heel elements 29 on the rib composite part 13. This means that end regions of the profile element 43 and the shoulder elements 29 form overlap regions 44.
• the profile element 43 is adapted and profiled to the spatial design of the underside of the rib composite part 13, which results in a very high torsional rigidity.
• connection area 45 in the overlap area 44 is e.g. formed as a fixed bearing 46, while a further connection area 47 is designed as a floating bearing 48, in which a length compensation between the profile element 43 and the rib composite part 13 or shoulder element 29 can take place.
• This floating bearing is designed in such a way that a longitudinal displacement is possible, for which purpose elongated holes 49 are provided in the profile element 43 in the area of the screw connections 38 and the shoulder element 29 and rib composite part 13 are spaced apart from one another by forming a receptacle 50 in the shoulder element 29 at a distance 51 that is slightly larger is as a thickness 52 of the profile element 43.
• this design enables the torsion forces to be absorbed and dissipated properly, but on the other hand enables length compensation in order to permit predetermined bending deformations.
• profile element 43 in addition to the fiber-reinforced plastic material already described for the profile element 43, a number of other materials, for example titanium / titaniumal, carbon, stainless steel sheet, etc., are possible.
• the basic requirement for the material is high strength with low weight and high resistance to environmental influences such as cold, moisture, salt, etc.
• stiffening webs 54 arranged on a surface 53, which extend between the heel elements 29.
• Damping intermediate layers 55 e.g. made of elastomers, between the heel elements 29 and the profile element 43 or the rib composite part 13 possible. These can consist of independent insert parts or can be molded on the shoulder elements 29 facing the rib composite part 13.
• FIGS. 1, 2, 3 can form the subject of independent solutions according to the invention.
• the relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
