Definitions

  • the present invention relates to a method of manufacturing a gliding board on snow by injection.
  • the invention also relates to a gliding board comprising lateral reinforcing elements.
  • a gliding board has a core which is made either pre-element, ie from injection and molding operations. During these operations, chemical compounds are introduced into a mold, and react with each other to to form a foam which, after a phase of expansion then of hardening, is finally form the nucleus in situ. More precisely, this expansion takes place in the volume defined between two outer layers, upper and lower, and between lateral reinforcing elements.
  • the top layer forms the whole superior protection and decoration of the board, the lower layer forms the outsole glide and reinforcing elements form all or part of the songs. then of the injection, and of the expansion that follows, these different elements are tackled against the die and the lid of the mold.
  • the mechanical properties of the injected gliding boards are directly related to the use of lateral reinforcement elements, as well as other component parts, which are the upper protection and decoration unit, at least one internal reinforcement and the gliding sole.
  • the choice of materials, dimensions and positioning of lateral reinforcing elements, as well as other constituent parts in relation to the nucleus, are preponderant to obtain the desired mechanical characteristics.
  • the core foam When the core foam is expanding then hardening, it fills vacant volumes and solidarises the various materials and parts it encounter on his way. To ensure a good positioning of the elements of lateral reinforcement and other component parts of the board during the injection operation, all are usually pre-assembled among themselves, before their positioning in the mold, to avoid their displacement during the push of the injected foam.
  • the pre-assembly or pre-bonding step is difficult to achieve in a very regular and very precise. It can lead to the formation of interstices generating leakage defects to the expanding foam, or the occurrence of bonding defects causing detachments when using the gliding board.
  • the pre-assembly stage requires specific tools and know-how, which leads to costs additional.
  • the use of adhesives or impregnating compounds based on thermosetting polymers, such as adhesives based on epoxy resins or polyurethane requires the use of organic solvents which are a source of pollution and of pollution.
  • a main problem that the invention proposes to solve is to point a method of avoiding the pre-assembly or pre-gluing step of elements, either lateral reinforcement, or the upper protection and decoration, with the internal reinforcements and / or the gliding sole.
  • Another problem is to realize a board comprising lateral reinforcing elements, at the level of of which come to position themselves and to solidify in a very precise way the whole superior protection and decoration, the internal reinforcement (s) and the sole of slides, without pre-assembly or pre-bonding operations.
  • the invention therefore relates to a method of manufacturing a gliding board on snow comprising in particular an injected core of foamed foam, at least one lateral reinforcing element forming all or part of the edge of the board and constituent parts.
  • the constituent parts are a set superior protection and decoration, at least one internal reinforcement and a sole of slips.
  • the method uses a step of injection in situ in a mold, compounds which react with each other to form a foam which, after one expansion then hardening, finally forms the core.
  • the process implement a step of providing for the lateral reinforcing element at less space, which subsequently allows circulation of this foam in phase of expansion between the lateral reinforcing element and at least one of the parts constituent immediately adjacent.
  • the method is characterized in that the space is obtained by one or more growths, presenting in the form of a boss, a rib or a paw, protruding from from the surface of the lateral reinforcing element and coming opposite the immediately adjacent constituent parts to ensure a bond between said one or more immediately adjacent constituent parts of the board and said lateral reinforcing element.
  • Lateral reinforcing element means lateral reinforcing element or lateral reinforcement element blank not yet machined.
  • the foam in formation and in expansion phase will flow from the injection site, to inside the nucleus volume, up to the volume of the space.
  • Such continuity in the volumes make it possible to obtain effective bonding only with the foam in phase Expansion and expanded and hardened.
  • the growths may be disposed on an upper face of a continuous or discontinuous wing unfolding at from a lateral face facing outwardly of the lateral reinforcing element and / or on an upper face of the lateral reinforcing element.
  • the one or excrescences may be intended to come into contact with a lower face of the upper set, so as to be able to create the space in which will be able to circulate the foam in the expansion phase for bonding the reinforcing element lateral with this upper set.
  • the growths may be arranged on a lower face of the lateral reinforcing element.
  • the one or excrescences may be intended to come into contact with an upper face of the footbed, so as to be able to create the space in which will be able to circulate the foam in the expansion phase for bonding the lateral reinforcing element with this gliding sole.
  • the growths may be arranged on a lateral face facing towards the inside of the reinforcing element lateral.
  • the growth or growths may be intended to come into contact with a face bottom of the internal reinforcement, so as to be able to create the space in which will be able circulate the foam in expansion phase allowing the bonding of the element of lateral reinforcement with this internal reinforcement.
  • Space can be favorably also obtained by one or more recesses or concavities formed from the face of the lateral reinforcing element and capable of come next to one of the component parts of the board.
  • the or the recesses or concavities can be filled by the expanded foam or can be filled with air.
  • a step of providing for this process at least one notch on a side face facing the interior of the element lateral reinforcement, allowing a nesting and a maintenance of a reinforcement internal. It is also possible to implement a step of predicting minus a rib or a discontinuous clip and a shoulder unfolding from a lateral face facing inwards of the lateral reinforcing element, allow insertion and maintenance of an internal reinforcement between the rib or clip and the shoulder.
  • a board of sliding on snow is characterized in that it is carried out according to the method as as described above.
  • a board for gliding on snow for example a ski Alpine (1), has a gliding sole (2) bordered by two side edges (3 and 4).
  • the ski (1) comprises an upper protection and decoration unit (6) forming the protection and decoration of the upper face of the ski (1).
  • the ski comprises two lateral reinforcing elements or lateral partial songs, the upper set of protection and decoration then forming a partial hull.
  • the partial side songs (7 and 8) go back to the whole height, the upper protection and decoration (6) coming to marry the upper face (9) of these songs (7 and 8).
  • the songs unfold from the side edges respectively, up to the upper set of protection and decoration, which is plan.
  • Substantially planar internal reinforcements are positioned in the internal structure of the ski (1). These types of reinforcements (11, 12 and 13) are generally made either of metal or based on fibrous materials, and in particular by laminates which may be fiberglass-based. Reinforcements, as described in documents FR-2.312.273, FR-2.818.915 and FR-02.14673 may be used.
  • the core (17) of the ski (1) is produced by injecting generating compounds polyurethane foam. This foam will diffuse and circulate in volumes free forming the core (17) then will harden.
  • the two blanks (16) have a continuous or discontinuous wing (18) extending substantially perpendicularly from the side face (19) of the blank (16) facing outwards.
  • the wing (18) itself has a fin continuous or discontinuous (21) extending substantially perpendicularly to the end of the wing (18) towards the edge (4).
  • the wing (18) and the fin (21) serve to place very precisely and firmly hold the blanks of the songs (16) to the interior of the mold (14).
