Definitions

  • the invention relates to a snowboard, in particular ski according to the preamble of claim 1 and in particular to a snowboard with a supporting shell which extends at the top of the snowboard and at least partially on the long sides of the snowboard and has a 3D shape.
  • the term "3D shape” is generally understood to mean a shape of the gliding board body or shell, which (shaping) in addition to the actual shell shape (with two legs on each longitudinal side of the door board body and with a yoke section connecting these legs ) has further contours on the upper side of the sliding board body, for example contours or projections on the upper side of the sliding board body, which extend over at least a partial length of the sliding board body, for example also in the middle region or binding region of a ski.
  • These projections or contours are e.g. designed elements and / or are used to hold ski sectionen connection or connection elements for a ski binding or for elements of a ski binding.
  • a snow sliding board is known ( FR 2 818 915 A1 ) with a GtoitbrettAvem whose top and the longitudinal sides are formed by a 3D shell. Under the shell is located on the Gleitbrettoberseite a top flange, which is slotted in some areas.
  • a method for producing a ski or Cleitbrett stresses using a molding press ( FR 2 696 354 A1 ), in such a way that the sliding board body has trough-shaped recesses on its upper side.
  • a surface layer forming the outer surface of the ski body is slotted at the edge of the depressions
  • the object of the invention is to provide a snow sliding board, in particular ski, whose supporting shell has the possibility of a simplified production in all sections of their 3D shape high strength.
  • a snow sliding board is designed according to claim 1.
  • the supporting shell in 3D form at least two layers executed, consisting of an outer surface layer, for which the usual in snowboard, relatively soft and easily deformable flat or Surface material consisting of a thermoplastic material, such as ABS (acrylonitrile-butadiene-styrene Copolimerisat), polyamide or polyester is used, and from the carrier layer of a flat or carrier material based on plastic, preferably from a fiber-reinforced (eg reinforced by glass or carbon fibers ) Plastic sheet, for example made of thermosetting plastic.
  • the carrier material used is, for example, a flat material available under the name IPT or IPTS.
  • This carrier material is for greater deformation, i. is not suitable for the formation of edges or corners or generally of transitions or structures with a very small radius of curvature by deformation, but has a high strength and can be easily and cleanly processed as a flat material, so that the invention as a whole a very simplified and clean manufacturing snow skates with a shell in 3D shape and high strength allows.
  • the supporting shell is formed by a laminate consisting of the flat or surface material forming the surface layer and also by the flat or carrier material forming the at least one carrier layer, and or in that the surface material is a thermoplastic material, for example ABS (acrylonitrile-butadiene-styrene copolymer), polyamide or polyester and or in that the flat or carrier material forming the at least one carrier layer is slit at those regions or transitions of the 3D shape on which the 3D shape has a concave profile on the outer surface of the snow gliding body, and or in that the flat or surface material forming the surface layer is a transparent plastic, and in that the surface layer is at its inside Page is colored and / or graphically designed, and or the flat or carrier material forming the at least one carrier layer is a fiber-reinforced plastic flat material, for example thermoplastic or thermoplastic plastic flat
  • ski body of a Schalenskis which is designed as a so-called 3D ski, with two extending in the ski longitudinal direction L over a partial length of the ski parallel or approximately parallel ridges or projections 2, each adjacent to a longitudinal side of the ski body 1 between form a trough-like depression 3.
  • the supporting shell 4 of the ski 1 follows this shape of the ski body, i. It also has the 3D shape, and consists of an inner carrier or carrier layer 5 and of an outer surface layer 6.
  • the usual for such layers flat material (decorative or surface film) is used, namely of a thermoplastic material, such as ABS (acrylonitrile-butadiene-styrene Copolimerisat), polyamide or polyester.
  • This sheet is sufficiently flexible and easily deformed under pressure or by pressing in the manufacture of the ski or shell 4.
  • a plastic flat or support material which, although highly resilient, but only limited deformable, for example, a fiber-reinforced plastic sheet, e.g. from a thermosetting plastic, for example a flat material, which is known under the name IPT or IPTS.
  • the shell 4 extends in the illustrated embodiment with its lower edges 4.1 to steel edges 7, which are provided in a conventional manner on the two longitudinal sides of the ski body 1 and together with the recorded between the steel edges tread 8 form the bottom or tread of the ski.
  • a suitable material for example made of fiber-reinforced plastic and / or metal (eg Titanal) upper and lower chords 9 and 10 and a core 11 of Ski stressess1 received, in the illustrated embodiment of a suitable plastic foam, such as PU foam is formed with inserts 12 of wood or other suitable material.
  • a suitable plastic foam such as PU foam is formed with inserts 12 of wood or other suitable material.
  • the surface layer 6, the carrier layer 5 and the top flange 9 are connected by non-illustrated intermediate or adhesive layers with each other.
  • the shell 4 forming components namely the surface layer 6 and the carrier layer 5 are inserted as a flat material, preferably as a flat laminate, which, inter alia, the surface layer 6, the support layer 5 and preferably as a further layer also already in the mold space of this molding Upper belt 9 has.
  • After closing the molding press is done by heating the molding of the shell 4 in its 3D shape.
  • adhesive layers or layers of hotmelt adhesive formed by a thermoplastic material and applied to the components (support layer 5, surface layer 6 and Upper belt 9) are applied or provided between them. It is also possible to choose the material for the carrier layer 5 so that when molding on this material (thermoplastic material), the connection between the components of the shell 4 and the dimensional stability of the shell 4 can be achieved.
  • the support material 5 is slotted where areas or transitions with a very small radius of curvature arise when the 3D shape of the shell 4 is formed. Such areas in the FIG. 1 are indicated with 13, for example, the transitions between the recess 3 facing inner sides of the projections 2 and the bottom of the recess 3.
  • the slot provided there in the substrate 5 is in the Figures 2 and 3 denoted by 14.
  • slightly deforming surface material 6 is also achieved by the slits 14 and 14 a, that from the carrier material and the surface material and gfs. also from the top flange 9 existing laminate when inserting into the mold for preforming the shell 4 to the shape of the interior of this tool at least in some areas applies and thereby centered in the mold, so that through the slits of the Support material 5 is achieved a significant simplification in the manufacturing process.
