Sports shoe, especially ski shoe
The invention relates to a sports shoe ( 1 ), in particular a ski boot ( 2 ), having a shell part ( 3 ) made from plastics. A shell base ( 11 ) of the shell part ( 3 ) forming support surface ( 12 ) an inner shoe ( 10 ) or foot ( 9 ) is provided in the form of an impact- and/or vibration-damping ribbed fitting, consisting of a shell wall and a ribbed lattice formed on a surface thereof remote from the support surface ( 12 ). Certain regions of this ribbed fitting are enclosed by a bending- and/or torsion-resistant profiled element ( 43 ) extending in a longitudinal direction substantially between a heel- and a ball-bearing region ( 32, 33 ) and secured between block elements ( 29 ) and the ribbed fitting by means of clamping and fixing means.
1. Sports shoe, comprising a shell part made from a plastics material with a cuff pivotably attached to the shell and at least one sole part attached to the shell part, wherein a shell base of the shell part forming a support surface for an inner shoe or foot is provided in the form of an impact- and vibration-damping ribbed fitting consisting of a shell wall and, disposed thereon on a surface remote from the support surface, a ribbed lattice, regions of which are enclosed by a profiled element extending in the longitudinal direction substantially between a heel- and ball-bearing region and fixed between block elements and the ribbed fitting by means of clamping and fixing means.
2. Sports shoe as claimed in claim 1 , wherein the block elements overlap with the profiled element at opposite overlap regions, the profiled element being retained in one of the overlap regions so as to be non-displaceable in the longitudinal direction and being longitudinally displaceable between the block elements and the ribbed fitting in the other overlap region.
3. Sports shoe as claimed in claim 1 , wherein the block elements have recesses for the profiled element in the clamping surfaces directed towards the ribbed fitting.
4. Sports shoe as claimed in claim 1 , wherein positioning pins are d in the ribbed fitting and project beyond it in order to position the profiled element and the block elements.
5. Sports shoe as claimed in claim 1 , wherein the profiled element is fixed in the longitudinal direction between the block element and shell base in the heel-bearing region.
6. Sports shoe as claimed in claim 1 , wherein the profiled element is retained so as to be longitudinally displaceable between the block element and shell base in the ball-bearing region.
7. Sports shoe as claimed in claim 1 , wherein the profiled element laterally encloses certain regions of the shell base in a substantially U-shaped arrangement.
8. Sports shoe as claimed in claim 4 , wherein positioning recesses in the profiled element and in the block elements are provided for the positioning pins.
9. Sports shoe as claimed in claim 8 , wherein the positioning recesses in the profiled element are elongate holes extending in the longitudinal direction.
10. Sports shoe as claimed in claim 1 , wherein the ribbed lattice of the ribbed fitting consists of longitudinal ribs extending in the longitudinal direction and transverse ribs extending perpendicularly thereto.
11. Sports shoe as claimed in claim 1 , wherein a distance between adjacent longitudinal ribs is smaller than a distance between transverse ribs extending perpendicularly thereto.
12. Sports shoe as claimed in claim 1 , wherein a rib height substantially corresponds to a thickness of the shell wall.
13. Sports shoe as claimed in claim 1 , wherein a thickness of the profiled element is approximately 0.5 mm to 2.0 mm.
14. Sports shoe as claimed in claim 1 , wherein the profiled element is made from high-strength plastics, a metal alloy, carbon, or sheet steel.
15. Sports shoe as claimed in claim 14 , wherein the profiled element is made from titanium-aluminum.
16. Sports shoe as claimed in claim 1 , wherein the block elements are fixed to the shell base with the profiled element inserted in between.
17. Sports shoe as claimed in claim 1 , wherein positioning recesses are provided on the shell base for the block elements.
18. Sports shoe as claimed in claim 1 , wherein the block elements are made from wear-resistant plastics.
19. Sports shoe as claimed in claim 1 , wherein the block elements are provided with an anti-slip coating.
20. Sports shoe as claimed in claim 1 , wherein damping inserts made from impact- and vibration-damping materials are provided between the block elements and the profiled element and/or the shell base.
21. Sports shoe as claimed in claim 1 , wherein the profiled element has stiffening webs on the surface remote from the shell base.
22. Sports shoe as claimed in claim 1 , wherein stiffening webs are arranged on the profiled element in the form of a web lattice.
23. Sports shoe as claimed in claim 22 , wherein a height of the stiffening webs substantially corresponds to the thickness of the profiled element.
