Abstract:
A sliding board, in particular a ski, includes a running surface, steel edges, an upper cup, a premanufactured core and at least one interface element connected to the sliding-board body by anchoring elements, for the arrangement of at least one binding element on the upper side of the sliding board. The anchoring elements have a head section held on the interface element or connected to the interface element, and have a shaft extending through an opening in the upper cup into the inside of the sliding board. In order to reduce installation operations on the finished sliding board, the interface element has been connected to the core during the building of the sliding board by at least one of the anchoring elements.

Description:
FIELD OF THE INVENTION 
   The invention relates to a gliding board, in particular a ski, comprising a running surface, steel edges, an upper cup, a prefabricated core, and comprising at least one interface element, for example a rail-like profiled guide element, which is connected to the sliding-board body by means of anchoring elements, for arrangement of at least one binding element on the upper side of the sliding board, whereby the anchoring elements have a head section held on the interface element or are connected to the interface element, and have a shaft extending through an opening in the upper cup into the inside of the sliding board. 
   BACKGROUND OF THE INVENTION 
   A sliding board with a profile-rail system is known from the EP 1 161 972 A1, which system consists of at least one rail extending in longitudinal direction of the sliding board, which rail is connected to the sliding-board body through at least one attached peg or peg section via a peg connection or peg anchoring. According to a preferred embodiment the profile rail is fastened in bores fittingly provided on the sliding-board body, into which bores expanding pegs are inserted and into the center bores of which bolts are pressed or driven while expanding. Thus the fastening of the profile rails occurs on the finished sliding board and replaces merely the otherwise common screw fastening. In order to make available a sliding board with an already premounted profile-rail system, it is therefore necessary to carry out fastening and installation operations on the finished sliding board. 
   SUMMARY OF THE INVENTION 
   The basic purpose of the invention is to make a sliding board available, in which profile-rail systems or other interface elements are connected to the body of the ski in such a manner that no subsequent fastening and installation operations on the finished sliding board are any longer necessary. 
   The set purpose is attained inventively by the interface element having been connected positively and/or frictionally and/or in another mechanical manner to the core during the building of the sliding board by means of at least one of the anchoring elements. 
   Thus the interface elements, which create the connection to the binding parts, for example a front jaw or a heel jaw of a ski binding, are bound or integrated during the manufacture of the sliding board or of the ski into the design of the same. Thus a separate fastening of the interface element on the finished sliding board is no longer necessary. 
   Sliding boards, in particular skis, which are designed according to the invention can be manufactured in a rational and technically simple manner. It is advantageous in this connection when the anchoring element has been connected to the upper cup prior to the positioning of the core. As an alternative to this it is possible for the anchoring element to be connected to a locking part held, in particular, foamed into the core. 
   Such a connection can be created in a simple manner by the shaft of the anchoring element having a recess, into which the locking part extends. 
   Another inventive modification provides that the shaft of the anchoring element is spread apart from below and is inserted into an opening of the locking part, which opening extends through the core. A different modification provides that a wedge part is inserted into the shaft of the anchoring element so that the anchoring element is held on the upper cup prior to the positioning of the core. 
   In the place of a wedge part it is possible for the shaft to be provided with a part screwed in from below or to be designed as such a part attachable in this manner. 
   A different modification provides that the shaft of the anchoring element is held on the upper cup like a rivet. Other inventive modifications each provide an intermediate part, which is designed in particular annularly or the like, and which is mounted on the shaft or on the screwed-in part. 
   The anchoring element is in a different embodiment of the invention held on the upper cup by means of a locking part. A design is particularly advantageous where the locking part has a keyhole-like or similarly designed opening in order to receive the shaft of the anchoring element, whereby the narrower opening section engages the shaft in the area of a local contraction. Also this design makes possible a simple and rational manufacture of the sliding board or ski. 
   The opening in the upper cup is in a further embodiment divided keyhole-like into two opening sections, which have different diameters, whereby also in the case of this modification the narrower section engages the shaft in the area of a local contraction.

   DETAILED DESCRIPTION OF THE INVENTION 
   The figures in the drawings illustrate different embodiments of the invention, whereby the exemplarily illustrated ski  1  has in all illustrations as the main parts a core  6 , an upper cup  5  ( 5 ′ in  FIG. 10 ) forming and enveloping the upper side and the two longitudinal sides of the ski  1 , which cup can be designed in one layer or multilayered, a running surface  2 , edges  3  consisting of steel (not illustrated in  FIG. 10 ) and a lower belt  4  between the running surface  2  and the core  6 . Further intermediate layers, for example an upper belt, can be inserted between the upper cup  5  and the core  6 . The ski  1  has recesses  8  at least in those areas, where rail-like profiled guide elements  7 , of which in each case only the one is illustrated, are arranged in pairs. A raised section  9  is provided between said recesses  8 . The rail-like profiled guide elements  7  with at least essentially fittingly designed foot sections  10  sit in the recesses  8 . The pair of rail-like profiled guide elements  7  is provided for arranging, guiding, slidingly movable shifting and the like of a ski binding or a ski-binding part—for example, a front jaw and a heel jaw of a safety ski binding. 
   Each guide element  7  has for this purpose on the section facing the adjacent ski side surface a guide bar  7   a  extending in longitudinal direction of the ski so that, for example, a base or support plate of a ski binding or of a ski-binding part can be moved onto the pair of guide elements  7  and can be fixed in longitudinal direction of the ski relative to the ski by not illustrated measures or mechanisms. Each guide element  7  has at least two, in particular, however, more than two receiving points  7   b  for insertion and passage of anchoring elements  11 , by means of which the guide elements  7  are connected to the ski  1  already during the manufacture thereof. The figures in the drawings show various possibilities of the connection, which will be described in greater detail hereinafter. 
   The anchoring element  11  in the embodiment illustrated in  FIG. 1  consists of a head  11   a  sitting and supported in the receiving point  7   b  and of a shaft  11   b  attached to said head and projecting out of the guide element  7 , which shaft is of a cylindrical shape and has centrally a comparatively wide gap  11   c  becoming wider toward the end of the shaft. 
   The core  6  of the ski  1  is a prefabricated core, which is at least partially, in particular totally, manufactured out of foam. Retaining parts  12 , which can be assembled with the anchoring elements  11 , are foamed into the foam material. Each retaining part  12  has a mounting part  12   a , which is freely positioned in the foam material so that the shaft  11   b  of the anchoring element  11  can be mounted with its gap  11   c  on the retaining part  12 . The blocking parts  12  are thereby fixedly anchored in the foam material, for example, by a number of anchor parts or anchor arms  12   b  embedded in the foam material. 
   The rail-like profiled guide elements  7  are during the manufacture of the ski  1  positioned on the already preformed upper cup  5 , the anchoring elements  11  positioned on the guide elements  7  are placed through openings  5   a  of the upper cup  5 , the core  6  is positioned by placing or pressing the shafts  11   b  of the anchoring elements  11  onto the mounting parts  12   a  of the retaining parts  12 . The ski  1  is completed with its further components and is molded in a form by adding pressure and heat. In case further layers are built in below the upper cup  5 , these are also provided with corresponding openings for passage of the anchoring elements  11 . 
   The anchoring elements  11  are in the embodiment according to  FIG. 2  provided with a shaft  13 , which has a recess  14 , into which a wedge part  15  can be inserted from below by expanding the shaft  13 . The recess  14  is designed round in the illustrated embodiment in order to receive a round, for example, tube-shaped wedge part  15 . The foam core  6  is manufactured or provided with recesses  16  in order to receive the shafts  13  of the anchoring elements  11 . The rail-like profiled guide elements  7  are during the manufacture of the ski, analogous to the embodiment according to  FIG. 1 , positioned on the upper cup  5  by means of the anchoring elements  11 , the wedge parts  15  are snapped into the recesses  14  of the shafts  13 , and the shafts  13  of the anchoring elements  11  are inserted or pressed into the recesses  16  in the core  6 . The ski  1  is completed and is molded in a form by adding pressure and heat. 
     FIG. 3  illustrates an embodiment, in which, similar to  FIG. 1 , a retaining part  17  for the anchoring element  11  has been bound in during foaming of the core  6 . The shaft  18  of the anchoring element  11  is designed slotted and can be spread apart. 
   The end sections of the two shaft parts separated from one another by the center slot  18   a  continue hook-like outwardly. The retaining part  17  bound in the foam material through anchor parts  20  is designed sleeve-shaped so that it has a central through opening. The rail-like profiled guide elements  7  are during the manufacture of the ski  1  positioned on the preformed upper cup  5  by means of their anchoring elements  11 . The, anchoring elements  11  are connected to the core  6  by inserting the shaft  18  into the sleeve-like retaining part  17 , whereby the hooks  19  snap in under shoulders  21 . A wedge  22  is inserted and driven from below into the slot  18   a . The ski  1  receives the remaining components and, as mentioned, is finished. 
   The shaft  23  of the anchoring element  1  is in the embodiment illustrated in  FIG. 4  anchored like a rivet. The shaft  23  is for this purpose designed expandable by means of a slot. A recess  24  is provided in the core  6  in order to receive the anchoring element  11 , which recess has already been formed during the manufacture of the core  6  or has been manufactured subsequently. The recess  24  has a shoulder  24   a , on which an in particular annular intermediate part  25  can be positioned. The intermediate part  25  consists, for example, of a plastic reinforced with fiber glass and has centrally an opening for passage of the shaft  23  of the anchoring element  11 . After the rail-like profiled guide elements  7  with their anchoring elements  11  have been positioned on the upper cup  5 , an intermediate part  25  is moved onto the shaft  23  of the anchoring element  11 . The anchoring elements  11  are placed through openings  5   a  into the upper cup  5 , on the edge sections of which openings the upper cup  5  is flanged inwardly. 
   The flanged edge sections of the upper cup  5  are received by open positions in the intermediate part  25 . The end sections of the shaft  23  are expanded, the core  6  with its recesses  24  is correspondingly positioned, the ski is finished and is molded in a form by adding pressure and heat. 
     FIG. 5  illustrates an embodiment, in which recesses  26  are also provided in the core  6 . The anchoring element  11  has a head  11   a , into which is screwed a shaft  27  in the form of a screw with a screw head  27   a . An intermediate part  28 , which consists, for example, out of a plastic reinforced with fiber glass, can be positioned in the recess  26  on a shoulder  26   a . The heads  11   a  are during the manufacture of the ski  1  screwed with the interpositioning of each one intermediate part  28  to the shafts  27  on the rail-like profiled guide elements  7 , which are positioned on the upper cup  5 , the foam core  6  is subsequently positioned, the ski  1  is completed with its further components and is molded in a form, as has been described. 
   The embodiment, which is illustrated in  FIG. 6 , is similar to the embodiment according to  FIG. 5 . The shaft  29  of the anchoring element  11  is in this modification completed by a part  29   b , which can be screwed on from below. A free space for flanged edge areas of the upper cup  5  is provided between the anchoring element  11  and the core  6  above the screw head  29   a , which can be inserted into a recess  30  in the core  6 . The guide elements  7  are positioned during the manufacture of the ski and the anchoring elements  11  are mounted by screwing on of the parts  29   b , the foam core  6  is subsequently positioned, the ski is finished and subsequently molded. 
   The embodiment illustrated in  FIG. 7  corresponds essentially with the one according to  FIG. 6 . In the place of flanged edge sections of the upper cup  5  in the area of the holes  5   a , an annular intermediate part  31  is provided. The rail-like profiled guide elements  7  are during the manufacture of the ski  1  positioned on the upper cup  5 , an intermediate part  31  is mounted from below onto the shaft  32  of the anchoring element  11 , and finally a part  32   a  is screwed to the shaft  32 . The core  6  having the corresponding recesses  33  is positioned, the ski  1  is finished and molded. 
   Through holes or bores  34  are provided in the core  6  in the embodiment illustrated in  FIG. 8  in order to receive the shafts  35  of the anchoring elements  11 . The end area of each hole  34 , which end area is in the area of the running surface, ends into a mentioned recess  34   a  so that an annular intermediate part  36  can be inserted here, which part can be connected to the shaft  35  by a screw  37 . The assembly of the individual parts is also in this embodiment very simple. The rail-like profiled guide elements  7  are positioned on the upper cup  5  by means of the anchoring elements  11 , as has already been described, the core  6  is placed over the shafts  35  of the anchoring elements  11 , the intermediate parts  36  are inserted into the recesses  34   a , and the screws  37  create the connection. The ski  1  completed with the further ski components is molded. 
   The anchoring element  11  is in the embodiment illustrated in  FIGS. 9 and 9   a  held by a locking part  38 , which has an opening  39  in the form of a keyhole.  FIG. 9   a  illustrates a top view of the locking part  38  with the opening  39  having two sections  39   a ,  39   b  with different diameters, which sections pass over into one another. The hole section  39   a  is sufficiently large in order to receive the shaft  40  of the anchoring element  11 . The hole section  39   b  is adapted to a local contraction  40   a  in the shaft  40 . When the rail-like profiled guide elements  7  are positioned on the upper cup  5  by means of the anchoring elements  11 , the locking parts  38  are mounted from below by being moved each with their larger hole section  39   a  onto the shaft  40 . The locking part  38  is subsequently moved such that the contraction  40   a  of the shaft  40  is positioned in the area of the hole section  39   b . The anchoring element  11  is in this manner fixed in its position. The foam core  6 , which has corresponding openings in order to receive the locking part  38  and the shaft  40 , is subsequently placed, the further ski parts are correspondingly positioned, and the ski  1  is molded in a form by adding pressure and heat. 
   The opening  50  in the upper cup  5 ′ is analogous to  FIG. 9   a  divided keyhole-like into two sections having different diameters in the modification illustrated in a longitudinal cross section (longitudinal direction of the ski) in  FIG. 10 . The shaft  41  of the anchoring element  11  is also in this modified embodiment provided with a contraction  41   a  so that the anchoring elements  11  positioned on the rail-like profiled guide elements are first placed on the upper cup  5 ′ through the larger sections of the holes  50 , are subsequently moved in longitudinal direction of the ski so that the contractions  41   a  move into the smaller sections. The anchoring elements  11  are in the moved position secured against a vertical lifting off from the upper cup  5 ′. The premanufactured foam core  6 , which has corresponding recesses for the anchoring elements  11 , is now positioned from below. The shaft  41  is thereby received by a diametrically opposed recess. The core  6  is furthermore formed such that it has a section  6   a  in order to cover the section  5 ′ b  of the hole  50  in the upper cup  5 ′. 
   The invention is not limited to the illustrated embodiments. Individual measures of the embodiments can be easily combined with one another. The anchoring elements are in all illustrated embodiments parts, which are manufactured separate from the rail-like profiled guide elements  7 . However, it is also possible to design the guide elements and their anchoring elements in one piece. Be it further mentioned that in place of a pair of rail-like profiled guide elements it is also possible to provide one single part, which permits a mounting of base plates, support plates and the like.
