Abstract

The heel part of the cross country ski binding with the suitably designed heel of the cross country ski boot according to the invention enables good torsion stability at push off and at the same time assures such position of the boot and accordingly of the foot and tibia, which enables the optimal conversation of the push off power and the energy of the runner into the skiing speed. The heel part of the binding (1) for cross country skiing according to the invention is realized in single piece, wherein the basic part (6) is designed as slightly projected, the oblique side walls (7a, 7b), realized on both sides, have trapezoid form and straight upper surfaces (9a, 9b) in the side-view. The cross country ski boot heel is suitably adapted to the form of the heel part of the binding according to the invention in the way, that on the outer and the inner heel side the edges (10) with properly designed landing (11) surgaces and contact surfaces (12) are realized, which accord with the side walls (7a, 7b) of the heel part of the binding (1).

Description

THE HEEL PART OF THE CROSS COUNTRY SKI BINDING WITH A SUITABLY DESIGNED HEEL OF THE CROSS COUNTRY SKI BOOT
The object of the invention is the heel part of the cross country ski binding, which in connection with the suitably designed heel of the cross country ski boot enables good torsion stability at push off during cross country skiing and prevents the accumulation of snow between the heel part of the binding and the heel of the cross country ski boot. The invention is classified to class A63C9/20 of the international patent classification.
The technical problem, which the hereby proposed realization of the heel part of the cross country ski binding according to the invention successfully resolves, is to assure the best possible torsion stability at push off during cross country skiing and at the same time to assure such position of the boot and accordingly of the foot and tibia, which enables the optimal conversion of the push off power and the energy of the runner into the skiing speed. Apart from the stated the solution of the presented technical problem according to the invention also prevents the accumulation of snow between the heel part of the binding and the heel of the cross country ski boot, which prevents sliding at push off, as it occurs at so far known constructions when the longitudinal grooves on the heel are filled with snow. One of the known solutions for the realization of the heel part of the ski binding is described in the US patent No. US 5,090,723. The solution offers the projecting guidance, which in connection with the longitudinal groove in the heel of the cross country ski boot prevents sliding of the boot to the side at push off. The problem of this solution is the fact, that when the longitudinal groove along the middle of the heel is filled with snow, it decreases the stability at push off, when the entire length of the sole contacts the binding. Because of that the push off is less explosive.
The presented technical problem is successfully solved with the heel part of the cross country ski binding. The main part of the submitted solution according to the invention is, that the cross country ski boot heel leans on the heel part of the binding with its outermost heel edges, the edges are not closed, which prevents snow accumulation and at the same time provides higher stability at push off. The heel part of the cross country ski binding according to the invention is realized in single piece, wherein the basic part is designed as slightly projected, the oblique side walls, realized on both sides, have trapezoid form and straight upper surfaces in the side view. The cross country ski boot heel is suitably adapted to the form of the heel part of the binding according to the invention in the way, that on the outer and the inner heel side the edges with properly designed landing surfaces and contact surfaces are realized, which accord with the side walls of the heel part of the binding. With the maximal possible distance between the side walls upper surfaces of the heel part of the binding, where the heel contacts the binding, better torsion stability at push off is assured.
The side walls of the heel part of the binding are higher than the side walls in so far known realizations, which assures such position of the cross country ski boot and accordingly of the foot and tibia, which enables the optimal conversion of the push off power and the energy of the runner into the skiing speed.
The invention is explained below in detail with a description of the realized example and the enclosed images, from which:
Figure 1 exhibits a back view of the heel part of the cross country ski binding with suitably designed heel part of the cross country ski boot according to the invention;
Figure 2 exhibits a perspective view of the heel part of the binding according to the invention;
Figure 3 exhibits a side view of the heel part of the binding according to the invention;
Figure 4 exhibits a back view of the heel part of the binding according to the invention; Figure 5 exhibits a perspective view of the heel with the sole according to the invention; Figure 6 exhibits a side view of the heel with the sole according to the invention;
Figure 7 exhibits a back view of the heel with the sole according to the invention;. Figure 1 exhibits the cross country ski boot 5 with the suitably designed sole 4 with the heel 3, set in the heel part of the binding 1 for cross country skiing according to the invention.
The heel part of the binding 1 , realized in single piece, has slightly projected basic part 6, on both longitudinal sides limited by two oblique side walls 7a and 7b of trapezoid form. The form of the basic part 6 enables unimpeded snow removal in the case, that during cross country skiing snow accumulates under the heel 3, the side walls 7a and 7b, which are higher from so far known realizations, assure such position of the boot 5 and accordingly of the sole and tibia, that the optimal conversion of the push off power and the energy of the runner into the skiing speed is enabled. Through the holes 8, realized on the basic part 6, fixation of the heel part of the binding 1 on the ski 2 with screws is enabled.
Upper surfaces 9a and 9b of the side walls 7 are flat, what enables perfect contact of the heel 3 and the heel part of the binding 1 at push off. The distance between the upper surfaces 9a and 9b of the side walls 7a and 7b, where the heel contacts the heel part of the binding, is the maximal possible, what assures better torsion stability at push off. The heel 3 of the cross country ski boot 5 is realized in such a way, that its form suits to the form of the heel part of the binding 1. On the outer and the inner side of the heel 3 the edges 10 with landing 11 and contact 12 surfaces, oblique with respect to the ski plane 2, are realized. The landing surfaces 11 land on the upper surfaces 9a and 9b of the side walls 7a and 7b of the heel part of the binding 1. The edges are not closed, which prevents snow accumulation and at the same time provides higher stability at push off.
