Full Description:
BACKGROUND OF THE INVENTION 
   The invention relates to a Snow glide board, in particular a ski, with at least one binding, which is held on one snow glide board body top side by locking sections interlocking behind or engaging undercuts on the snow glide board body, wherein insert apertures are provided on the top of the snow glide board for inserting the locking sections in the undercuts, each of which apertures passes into one undercut and are preferably open on or towards the top of the snow glide board. 
   A snow glide board in the form of a ski, in which the binding is fastened to the top of the ski body with a bayonet-type latching device is known in the art (EP 0 383 104 B1). This latching device is achieved, in particular by an open groove in both longitudinal sides of the ski body, or in the side walls there, and by binding plates with a C-shaped cross section or C-shaped Profile that positively lock with its bent ends behind the ski body in the area of this groove. In order to enable the insertion of the bent ends of the respective C-profile into the grooves, the side walls are provided with additional recesses, by which the grooves are open laterally toward the top of the ski body, so that each binding plate can be locked onto the ski body in the manner of a bayonet by placing it on the ski body and then sliding it longitudinally. 
   Although this known ski enables the easy fastening and/or replacement of the binding, the known construction has a number of disadvantages, e.g. because the binding plates bearing the binding elements necessarily extend over the longitudinal sides of the ski body, and also because the grooves in the side wall result in weakening of the ski body, and therefore the strength of the anchoring of the binding to the ski body is limited due to the relatively low height of the side walls and due to the material normally used for side walls. 
   It is an object of the present invention is to provide for a snow glide board that retains the basic advantages of a bayonet-type fastening of the binding of binding elements while enabling a construction that is not detrimental to the running characteristics of the snow glide board. 
   SUMMARY OF THE INVENTION 
   This object is achieved by a snow glide board, in particular a ski, with at least one binding, which is held on one snow glide board body top side by locking sections interlocking behind or engaging undercuts on the snow glide board body, wherein insert apertures are provided on the top of the snow glide board for inserting the locking sections in the undercuts, each of which apertures passes into one undercut, an wherein the undercuts are formed by connecting elements anchored on the snow glide board top.

   DETAILED DESCRIPTION OF THE INVENTION 
   In the drawings,  1  generally designates a ski body  2 , which is designed using the conventional ski construction materials and essentially in the conventional manner. Accordingly, the ski body  2  consists for example of the inner core  3  with a torsion box  4  for example made of a fiber reinforced plastic material and surrounding said core, of the running surface coating  5  with the lateral steel edges  6  forming the ski body bottom  2 . 1 , of the upper reinforcing layer or belt  7  above the core  3  and the lower reinforcing layer or belt  8  between the torsion box and the running surface coating  5 , of the side walls  9  forming the longitudinal sides of the ski and of a decorative surface foil  10  forming the top and also partially the longitudinal sides of the ski body  2 . 
   In the depicted embodiment, the core  3 , the torsion box  4  and e.g. also the upper belt  7  are formed so that the ski body  2  forms on the ski body top  2 . 2  two projections  11  that both extend parallel to each other and at a distance from each other in the longitudinal direction of the ski body, for example over a great part of length of the ski body or over the entire or nearly the entire length of the ski body. On the inner sides  11 . 1  of the projections  11 , which sides face one another, connecting elements  13  and  14  are inserted into recesses  12 , which are located in the central area of the ski body  2  and in the binding area and which are open toward the other corresponding projection and toward the top of the ski  1 . On each projection in one direction from the rear end  2 . 3  of the ski body  2  toward the shovel area  2 . 2  of said ski body, first the connecting element  13  and then the other connecting element  14  is provided in the longitudinal direction of the ski body at a distance from the first connecting element  13 . 
   The connecting elements  13  and  14  in the depicted embodiment are essentially strip-shaped shaped bodies  15  and  16  extending in ski longitudinal direction and made of metal and/or plastic. These shaped bodies are each designed with one groove  17  that is open on one connecting element longitudinal side  13 . 1  or  14 . 1  and that is however closed on both ends of the respective connecting element  13  or  14  and are fastened in the recesses  12  in a suitable manner, for example by screws and/or by molded pegs and/or by means of gluing, etc., so that the two connecting elements  13  are located directly opposite of each other perpendicular to the longitudinal extension of the ski with the open side of their grooves  17  in pairs, as are the two connecting elements  14 . 
   In order that the connecting elements  13  and  14 , which are flush on their top side with the top side of the respective projection, do not neither protrude over the top side of the respective projection or ski body, nor impair the flexibility of the ski body  2 , they are segmented, i.e. they are provided with groove-shaped notches  18  extending perpendicular to their longitudinal extension so that each connecting element  13  and  14  and the corresponding shaped body  15  and  16  forms a total of four segments  15 . 1 - 15 . 4  and  16 . 1 - 16 . 4 . These segments are connected only by means of material sections  15 . 5  and  16 . 5 , which, when the connecting pieces are mounted, are located on the lower limit of the respective recess  12  facing the bottom of the ski body  2 . 1 . 
   In the depicted embodiment the connecting elements  13  and  14  and their shaped bodies  15  and  16  are both of the same length. Furthermore, each shaped body is divided by the notches  18  into four segments of the same length. 
   On the top of the connecting element  13  or on the top of the segments  15 . 1  and  15 . 3  each connecting element  13  is provided with an aperture  19 , which in the depicted embodiment extends over the entire length of the respective segment, from the edge of the groove  17  to the bottom of this groove. By means of the recesses  19 , locking sections  21  provided on the bottom of one binding element, for example on the bottom of one binding plate  20 , can each be inserted into one groove  17  of the connecting element  13  by placing it on top, for which the length of the locking element  21  in the longitudinal direction of the binding plate  20  or the longitudinal direction of the ski is equal to or slightly less than the corresponding length of the recesses  19 . By moving the binding plate  20  in the longitudinal direction of the ski by the length of one segment  15 . 1 - 15 . 4 , the binding plate  20  can be anchored with its locking elements  21  on the two connecting elements  13  and therefore on the top of the ski body  2 . 2 . In the depicted embodiment, the binding plate  20  comprises two pairs of strip-shaped locking elements  21  on its bottom side. 
   The distance between the locking elements  21  on each longitudinal side of the binding plate  20  is then likewise equal to the distance between the recesses on the connecting elements  13 . In the depicted embodiment the locking sections  21  are formed by corresponding profiling of the binding plates. The rear end of the binding plate  20  is therefore anchored doubly on each connecting element  13 , i.e. by means of double overlapping. In fastened state, the binding plate  20  lies with its two longitudinal edges on the top of the projections  11  and on the top of the connecting elements  13  and  14 , so that the support of the binding plate  20  on the ski body  2  is far outward for optimum transfer of force between the binding and the ski. 
   In the area of the rear end of the binding plate  20  the rear binding element  22  can be adjusted in the longitudinal direction of the ski, as indicated by the double arrow. 
   The connecting elements  14  and the corresponding shaped parts  16  each have a recess  23  corresponding to the recess  19  on the first segment  16 . 1  in the axis direction “ski body end  2 . 3 -shovel  2 . 4 ”. The remaining segments  16 . 2 - 16 . 4  connecting in the direction of the front of the ski and in the direction of the shovel area  2 . 4  are not provided with the recess  23 . The front binding element  24  (binding toe piece) is fastened to the front end of the binding plate  20  so that it can be adjusted in the longitudinal direction of the binding plate  20  (double arrow B). The binding element  24  is designed on its bottom side corresponding to the binding plate  20 , with one locking section  21  on each longitudinal side. With these connecting sections  21 , the binding element  24  connected with the binding plate  20  can be inserted via the recesses  23  into the groove  17  of the front connecting element  14  and locked into position there through axial movement of the binding plate  20 . Since the connecting elements  14  comprise a plurality, i.e. in the depicted embodiment a total of three segments  16 . 2 - 16 . 4  without the recess  23  and arranged consecutively in the longitudinal direction of the connecting element, after locking of the binding element  24  and therefore also of the front end of the binding plate  20  to the connecting elements  14  and to the ski body  2 , a longitudinal adjustment (double arrow B) of the binding element  24  relative to the binding plate  20  is possible while remaining locked to the ski body  2 . The embodiment preferably enables the insertion of the locking sections  21  on the binding plate  20  and on the front binding element  22  into the corresponding recesses  19  and  23  when the front binding element  24  is in one of the two end positions of its adjustment (double arrow B) relative to the binding plate  20 , i.e. in the depicted embodiment in the end position in which the binding element  22  is nearest the base plate  20 . 
   After insertion of the locking sections  21  of the binding plate  20  and of the binding element  24  through the recesses  19  and  23  into the groove  17  of the connecting elements  13  and  14  and after locking by longitudinal sliding, this locking of the sections  21  or of the binding plate  20  is secured by suitable means, for example by fixing the binding plate  20  to the ski body  2  by means of a pin, etc. 
   The invention was described above based on an exemplary embodiment. It goes without saying that modifications and variations are possible, without abandoning the underlying inventive idea upon which the invention is based.
