Fixation of binding board to splitboard skis

Abstract

Systems and methods for fixing a binding board to skis that are removably connected together to form of a splitboard are described herein. In some cases, the described systems use a sliding and removable setting of bearing pins in eyes that are formed on adjacent areas of the board and a clamp that is fixed to the skis. The essence of the invention is a fixation of lateral parts of the eyes by stoppers which partially overreach into cross sections of the eyes. A diameter of the bearing pins basically corresponds with a diameter of the eyes. The bearing pins are equipped with circular recesses for engaging with the stoppers and also with end parts that each have a truncated conical tip.

A coupling system for fixing a board of a binding to a ski of a splitboard that is formed by two skis that are connectable to a form a snowboard, wherein the coupling system comprises at least two bearing pins and at least two eyes, wherein the at least two bearing pins are configured to selectively and respectively slide into the at least two eyes, wherein the at least two eyes are formed coaxially with each other, wherein a stopper is disposed adjacent to each of the at least two eyes, wherein each stopper extends past and into an inner diameter of the first of the at least two eyes, wherein an outer diameter of each of the at least two bearing pins substantially corresponds with inner diameters of the at least two eyes, wherein a tip of each of the at least two bearing pins defines a circular recess having a spacing that corresponds with a location of each stopper, and wherein each of the at least two bearing pins is equipped with an end part having a truncated conical tip.

2. The coupling system according to claim 1, wherein, the at least two eyes are formed on a front portion of the board of the binding, wherein the at least two eyes are offset laterally from each other on the board of the binding, and wherein the at least two bearing pins are fixed on a clamp that is configured to couple to the ski of the splitboard.

3. The coupling system according to claim 1, wherein, the truncated conical tip is beveled and a first edge of a beveled portion of the truncated conical tip comprises a planar surface that is tangential to a cylindrical area of the circular recess.

4. The coupling system according to claim 2, wherein, the truncated conical tip is beveled and a first edge of a beveled portion of the truncated conical tip comprises a planar surface that is tangential to a cylindrical area of the circular recess.

EXAMPLES OF DESIGN OF THE INVENTION

(10) The invention is designed for use for a splitboard which is formed by two skis 1 (as illustrated in FIG. 1), which are, by the help of two couplers of unmarked central connectors and two vertex connectors on a tip and a foot of standard design ski 1 such that the two skis are selectively couple together into a shape of a snowboard board. The subject of protection is fixation of a hoard 2 of a binding to a ski 1 by the help of its fixation with a front clamp 3 which is illustrated in FIG. 2.

(11) On a front face 21 of the hoard 2 are formed two eyes 22, which are with regard to a lengthwise axis of the hoard 2 laterally, offset, whereas next to these eyes 22 are in the front face 21 fixed stoppers 23, which are formed and positioned in the way that they partially overreach into cross section of the eyes 22. The front clamp 3 is formed by a flat fork console, which has a broken connecting cross member 31 on its vertex and also in end parts of side arms 32 equipped with unmarked openings which enable selectively removable fixation of the clamp 3 to the ski 1 by the help of screw connections. On the side arms 32 are coaxially formed cases 33 in the way that their spacing is equal with spacing of the eyes 22 which are formed on the front face 21 of the board 2. In the cases 33 is fixed a couple of co-directionally oriented bearing pins 4, whose diameter basically corresponds with the diameters of the eyes 22 of the front face 21 and Which are equipped with circular recesses 41, whose cross section corresponds with the cross section of fixation of the stoppers 23 on the front face 21 of the board 2 and also are equipped with an end part with a one-sidedly from above truncated conical tip 42 (or a conical tip that is truncated on one side) formed in the way that the upper edge of its reduction is in a plane that is tangential to a cylindrical area of the circular recess 41.

(12) During assembly of the splitboard, its stationary functional elements, namely the front clamps 3, are fixed, into predetermined positions on both skis. During reconfiguration of the splitboard into ascending mode are at first unlocked locks of central connectors and vertex connectors and the skis 1 are placed into a position (as illustrated in FIG. 1). Then each board 2 is placed into a vertical position (which is illustrated in FIG. 4a) and laterally with its eyes 22 is placed into the cases 33 of the clamp 3 (as is clear from the FIG. 4b). In the next step, the board 2 is turned 90°, (as is illustrated in FIG. 4c), and herewith comes to locking the stopper 23 into the circular recess 41 of the bearing pin 4 of the clamp 3 and coupling the board 2 with the ski 1. By this step is installation terminated. For release of the board 2 from the clamp 3 is the process performed in reverse order.

(13) The described design is not the only possible solution according to the invention. Indeed, without changing the essence of the invention, it is possible to design the connecting cross member 31 of the clamp 3 and its side arms 32 according to the size and design of the board 2. Also, it is not important if the eyes 22 are formed on the board 2 and the bearing pins 4 on the clamp 3 or if are these elements formed in an opposite way, thus the bearing pins 4 on the front face 21 of the board 2 and the eyes 22 on the clamp 3, as it is illustrated in FIG. 5.

INDUSTRIAL UTILITY

(14) The design of fixation of the board of the binding to a ski is designed for use for the splitboard whose design is aimed at provision of maximal comfort of the users with guarantee of simple manipulation during reconfiguration and minimization of failures of functional components.
