Description:
BACKGROUND OF THE INVENTION  
       [0001]     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.  
         [0002]     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  
       [0003]     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.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0007]     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°.  
         [0008]     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 .  
         [0009]     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 .  
         [0010]     In the embodiment of the snowboard  1   a  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  2   a.    
         [0011]     In this embodiment, the lower belt  9  is provided over the entire length of the snowboard corpus  2   a  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 .  
         [0012]     In the described embodiment of the snowboard  1   a , 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 .  
         [0013]      FIG. 4  shows as a further possible embodiment a snowboard  1   b , 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  8   b , 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  2   b  from the adjacent edge area  12 . 3  in the direction of the width of the snowboard corpus  2   b , i.e. in an axis direction perpendicular to the longitudinal extension of the snowboard  1   b  and parallel to the lower running surface, whereby y is approximately equal to the width of the crosspiece  12 . 1  in this axis direction.  
         [0014]     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 .  
         [0015]     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 .  
         [0016]      FIG. 5  shows as a further embodiment a snowboard  1   c , the snowboard corpus  2   c  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 .  
         [0017]     Outside of the section  3 . 1  the snowboard corpus  2   c  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 .  
         [0018]     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  1   c  and in relation to the adjacent edge area  12 . 3 .  
         [0019]     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.  
         [0020]     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 .  
         [0021]     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.
