Description:

BACKGROUND OF THE INVENTION

The invention relates to a snow glide board and in particular a snowboard or ski. Snow glide boards of this type are known in various embodiments. It is an object of the invention to demonstrate a snow glide board, and in particular a snowboard, which provides an increased degree of riding pleasure.

This objective is achieved by a snow glide board, snowboard, or ski, according to the invention, that enables both the usual riding or boarding and so-called rail riding or grinding, i.e. cross sliding on rails, beams, edges, bars etc. existing on the terrain, without hindrance by the steel edges or their edge areas needed for the edge grip in normal riding or boarding.

SUMMARY OF THE INVENTION

The snow glide board, snowboard, or ski, has a glide board corpus which includes a running surface coating with steel edges on one bottom side. The steel edges form an edge area for an edge grip and are located on one long side of the glide board corpus, whereby in a section between the ends of the glide board corpus—at least one of the steel edges is set back by an amount (x) in relation to one plane or level (N) of the running surface formed by the running surface coating to the top of the snow glide board.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is described below based on exemplary embodiments with reference to the drawings, in which:

FIG. 1 shows a simplified representation in top plan view of a snow glide board in the form of a snowboard according to the invention; and

FIGS. 2-5 show various possible embodiments of the snow glide board according to the invention in a fragmentary perspective view taken in cross section, in the middle area of the snowboard and between the two bindings.

DETAILED DESCRIPTION OF THE INVENTION

In the drawings, a snowboard 1, is disclosed, which includes a snowboard corpus 2 with two tapered or concave long sides 3 forming a sidecut. The two bindings 4 and 5, which are only schematically indicated in FIG. 1, are provided on the top of the snowboard corpus. As further depicted in FIGS. 2-5, the snowboard corpus 2 is manufactured using the usual materials, with a core 6, e.g. made of wood, with the side faces made of plastic, e.g. of ABS, enclosing the core 6 on the perimeter of the snowboard corpus 2, with an upper reinforcing element or belt 8 connected to the top side of the core and a lower reinforcing element or belt 9 connected to the bottom side of the core, both made of a suitable material, e.g. fiber-reinforced plastic and/or metal (e.g. titanal), with one surface or decorative foil forming the top of the snowboard corpus 2 and with one lower sliding or running surface component connected to the lower belt 9 and consisting of the sliding or running surface coating 11 and the steel edges 12 that are necessary for the edge grip of the snowboard and extend along each long side 3 and limit the running surface on the side of the snowboard formed by the running surface coating 11 with their crosspieces 12.1. The steel edges 12 have the usual L-shaped profile with the crosspiece 12.1 and the shank 12.2, which protrudes laterally with a large width over the crosspiece 12.1 and on which the respective side face 7 is supported directly or indirectly, in each case over the entire width of the shank 12.2. The steel edges 12 are shaped or sharpened for the edge grip so that they have the sharpest possible edge area 12.3 on the outside of the crosspiece 12, i.e. an edge area 12.3, which is formed by the two flat crosspiece surfaces at a distance from the shank 12.2 that together form an angle of approx. 90° or somewhat greater than 90°.

The flat upper belt 8 lies with its edge on the top of the respective side face 7 and is connected there with the side face 7. The for example flat decorative foil 10 covers the upper belt 8 also in the area of its edge that is connected with the top of the side face 7.

All of the embodiments described in FIGS. 2-5 have in common that—in a middle section 3.1 of each long side, i.e. between the two bindings 4 and 5 where also the distance between the two long sides 3 is smaller due to tapering—the two steel edges 12 are so provided for on the two long sides 3 or are so shaped that they are set back from the level N of this running surface by an amount x in a direction perpendicular to the plane of the running surface and in the direction toward the top of the snowboard corpus 2 formed by the foil 10, while—outside of this area or section 3.1, i.e. in particular at the front and rear sections 3.2 of the long sides—the steel edges 12 and their edges 12.3 lie on the plane N of the bottom of the snowboard corpus or its running surface. This enables rail riding or grinding with the snowboard 1, i.e. cross sliding on a terrain cross rail or edge without hindrance from the steel edges 12.

In the embodiment of the snowboard 1a depicted in FIGS. 2 and 3, this setting-back of the steel edges 12 and of the edge area 12.3 is achieved by the fact that at the beginning of the respective section 3.1, the steel edges 12 and their edge areas 12.3 extend first from the level N in the direction of the top of the snowboard corpus and then over a length parallel or essentially parallel to the top of the snowboard and, at the end of the section 3.1, back to the level N. The running surface coating 11 is then beveled on each edge at 11.1 in the area 3.1 such, that the running surface coating extends also in the section 3.1 with the bevel 11.1 to the side of the crosspiece 12.1 which side faces the shank 12.1 and that the running surface coating covers the shank 12.2 toward the bottom of the snowboard corpus 2a.

In this embodiment, the lower belt 9 is provided over the entire length of the snowboard corpus 2a with its edges between the steel edges 12 and the bottom of the side face 7 and is connected with these elements in a suitable manner, e.g. by gluing, etc. Furthermore, the side faces 7 in this embodiment possess a height that varies corresponding to the shape of the steel edges 12.

In the described embodiment of the snowboard 1a, the steel edges 12 and their edge areas 12.3 in the sections 3.1 are shifted upward in relation to the lower running surface of the snowboard, so that again grinding or rail riding, i.e. cross sliding, is possible without hindrance by the steel edges 12.

FIG. 4 shows as a further possible embodiment a snowboard 1b, in which the setting-back of the steel edges 12 and of the edge areas 12.3 in the sections 3.1 is achieved by the fact that the running surface coating in these sections protrudes over the side of the crosspieces 12.1 facing the bottom of the snowboard corpus 8b, thus forming a further, rounded edge area 11.2 below the steel edges 12 on the level N of the running surface in the respective section 3.1. This edge area is offset by an amount y toward the middle of the snowboard corpus 2b from the adjacent edge area 12.3 in the direction of the width of the snowboard corpus 2b, i.e. in an axis direction perpendicular to the longitudinal extension of the snowboard 1b and parallel to the lower running surface, whereby y is approximately equal to the width of the crosspiece 12.1 in this axis direction.

In this embodiment the lower belt 9 bears with its edge areas against the edge areas of the running surface coating 11. Outside of the two sections 3.1, the lower belt 9 and the running surface coating 11 are accommodated in the angle area of the steel edges 12 formed by the crosspiece 12.1 and the shank 12.2, i.e. both the lower belt 9 and the running surface coating 11 extend with their edge areas all the way to the side of the crosspiece 12.1 facing the shank 12.2.

In the sections 3.2, the steel edges 12 then bear with their shanks 12.2 directly against the edges of the lower belt 9. In the sections 3.1, additional material 13 is inserted between the shank 12.2 and the adjacent edge of the lower belt 9, so that the running surface coating 11 protrudes downward over the steel edges 12 in the described manner, thus forming the additional rounded edge area 11.2. The core 6 is also adapted accordingly in thickness, so that the running surface coating 11 forms a flat or essentially flat running surface also between the sections 3.1.

FIG. 5 shows as a further embodiment a snowboard 1c, the snowboard corpus 2c of which comprises one additional steel edge 14 in the sections 3.1, which (steel edge) again has the usual L-shaped profile consisting of the crosspiece 14.1 and the shank 14.2, the latter, however, having a rounded edge area 14.3.

Outside of the section 3.1 the snowboard corpus 2c is designed so that the lower belt 9 and the running surface coating 11 extend with their edges all the way to the side of the crosspiece 12.1, facing the shank 12.1, of the steel edges 12 with the sharpened edge area 12.3, whereby the side faces 7 then bear directly against the top of the steel edges 12.

In the sections 3.1, the lower belt 9 extends with its edge areas only to the side of the crosspieces 12.1 of the steel edges 12 facing the respective shank 12.2, while on the edge areas of the running surface coating 11, the additional steel edge 14 is provided, so that the edges of the running surface coating 11 in these sections 3.1 extend all the way to the side 14.1 facing the respective shank 14.2. In this embodiment also the edge areas 12.3 in the sections 3.1 are again set back by the amount x in the direction perpendicular to the plane of the running surface in relation to the level N. At the same time each rounded edge area 14.3 is offset toward the middle of the snowboard by the amount y in the transverse direction of the snowboard 1c and in relation to the adjacent edge area 12.3.

In this embodiment the additional steel edges 14 bear against the adjacent steel edge 12, so that y in this embodiment is smaller than the width of the crosspiece 12.1. Generally, it is also possible, however, that the additional steel edges 14 are arranged so that they do not bear directly against the steel edges 12, but instead indirectly via edge areas of the lower belt or via additional inserted material, etc.

It goes without saying that the hollow spaces existing in the depiction of FIGS. 2-5 not occupied by described materials are completely filled with a material used during the manufacture of the individual snowboard, e.g. synthetic resin, etc. In all described embodiments the dimension x is approximately equal to or slightly larger than the height of the steel edges in the axis direction perpendicular to the running surface and the dimension y is approximately equal to the width of the crosspiece 12.1.

The invention was described above based on exemplary embodiments. It goes without saying that modifications and variations are possible, without abandoning the underlying inventive idea of the invention.
