Board-like sliding device in the form of a ski or snowboard
The invention relates to a board-like sliding device in the form of a ski or snowboard. Said board-like sliding device comprises a multilayered sliding board body and at least one elongated force-transmitting element supported on the upper side of the sliding board body for influencing the bending resistance or the vibrational behavior of the sliding board body as well as a binding device for a potentially detachable connection with a sports shoe. Between the lower side of the force-transmitting element and the upper side of the sliding board body at least one engaging coupling means is formed. The force-transmitting element is designed in this case as a thin-walled shell body with a wall thickness of less than 5 mm, which at least over the main part of its longitudinal extension has a substantially U-shaped cross section. At least part sections of the side arms of the force-transmitting element run at least partly in groove-like depressions on the upper side of the sliding board body.
1. A board-like sliding device in the form of a ski or snowboard, comprising a multi-layered sliding board body with a strength-relating upper layer, at least one strength-relating lower layer, at least one cover layer forming an upper side of the sliding board body having grooves arranged thereon, and at least one running surface coating forming a lower side of the sliding board body, a binding device for an optionally detachable connection with a sports shoe, and with at least one elongated force-transmitting element including side arms arranged at last partially within the grooves and supported on the upper side of the sliding board body for influencing the bending resistance or the vibrational behaviour of the sliding board body, and an engaging coupling means arranged between the lower side of the force-transmitting element and the upper side of the sliding board body, wherein the force-transmitting element is designed as a thin-walled shell body with a wall thickness of less than 5 mm, which has at least within the main part of its longitudinal extension a substantially U-shaped cross section.
2. The board-like sliding device according to claim 1 , wherein the shell body comprises plastic, which is formed by means of a heating press into a shell or U-shaped moulding.
3. The board-like sliding device according to claim 1 , wherein the lower side of the substantially U-shaped shell body is supported within the assembly section for a binding device in a load-transferring manner on the upper side of the sliding board body.
4. The board-like sliding device according to claim 1 , comprising a cavity arranged at an end section of the shell body between the lower side of the shell body and the upper side of the sliding board body.
5. The board-like sliding device according to claim 1 , comprising support elements for supporting in a load-transferring manner a binding device relative to the upper side of the sliding board body, the shell body within the assembly section for a binding device comprising a plurality of openings, support elements extend into respective ones of the openings.
6. The board-like sliding device according to claim 5 , wherein the support elements comprise platform-like elevations on the upper side of the sliding board body designed to be integral with the sliding board body.
7. The board-like sliding device according to claim 5 , wherein an insertion part is formed, which connects the support elements into a one piece component group, the sliding device further comprising an insertion part arranged between the upper side of the sliding board body and the lower side of the shell body.
8. The board-like sliding device according to claim 7 , wherein a lower part section of the insertion part is held in position in depressions on the upper side of the sliding board body.
9. The board-like sliding device according to claim 1 , wherein the shell body is secured within the assembly section for a binding device to prevent lifting from the upper side of the sliding board body, in that it is held between the underside of a mounted binding device and the upper side of the sliding board body.
10. The board-like sliding device according to claim 1 , wherein the shell body is mounted to slide freely relative to the lower side of a mounted binding device in the direction of the longitudinal axis of the shell body.
11. The board-like sliding device according to claim 1 , comprising securing screws anchored in a load-bearing manner for the assembly of a binding device only in the sliding board body.
12. The board-like sliding device according to claim 1 , wherein the shell body in side view has a curved longitudinal extension, so that its distal end sections in the mounted state are supported by elastically flexible tensioning on the upper side of the sliding board body.
13. The board-like sliding device according to claim 1 , wherein the bending resistance of the sliding board body is higher than the bending resistance of the shell body, and in that the shell body mounted on the upper side of the sliding board body is largely stressed by pressure or tension and thus influences the bending resistance or the vibrational behaviour of the ski or snowboard.
14. The board-like sliding device according to claim 1 , wherein the side arms include end sections and are covered visually at least partly by side walls.
15. The board-like sliding device according to claim 1 , wherein the force-transmitting element is connected to the sliding board body via a plurality of connecting zones spaced apart form one another in the longitudinal direction of the force-transmitting element.
16. The board-like sliding device according to claim 15 , wherein within at least one connecting zone an elastically flexible connecting means is provided in the longitudinal direction of the sliding board body.
