Definitions

  • the invention relates to the field of snow sliding sports. She aims more particularly a new board structure, that is to say alpine or derivative skiing, such as Nordic skiing, as well as snowboarding. She aims more particularly a new board structure, and a method of associated manufacturing, which make it possible to produce boards with injected core whose upper side has marked relief effects, the internal structure of which has rigid reinforcements.
  • gliding boards have a core which is made either as a pre-element, or from injection and molding operations during which chemical components are introduced into a mold, and react so as to expand to form the nucleus in situ. Specifically, this expansion takes place in the volume defined between two upper outer layers and lower respectively forming the upper protective layer of the board and the gliding sole, as well as lateral reinforcing elements, forming all or part of the songs. During injection, and the subsequent expansion, these different elements are pressed against the die and the mold cover.
  • the mechanical properties of the injected skis are directly related to the use of internal reinforcements which generally have strong rigidity.
  • This type of reinforcement is generally made either of metal or based on fibrous materials, and in particular by laminates which may be based glass fibers.
  • the choice of materials, as well as the dimensions of the reinforcement and its positioning within the nucleus, are preponderant to obtain the desired mechanical characteristics.
  • All reinforcements substantially planes known to date are generally arranged either in contact with the layer forming the sole or the upper protective layer, possibly with the interposition of other specific reinforcements. To ensure proper positioning of the reinforcement during the injection operation, the latter is generally glued previously on the outer layer in contact with which it comes, which avoids the displacement of this reinforcement during the movement of the foam polyurethane.
  • a problem which the invention proposes to solve is that of being able use reinforcements whose height is optimized to give stiffness specific to the board. Another problem is that of keeping the reinforcement intrinsic properties so as to influence the stiffness of the plank of the desired way.
  • this board is characterized in that the internal reinforcement rests on recesses provided for this purpose in each of the lateral reinforcement elements.
  • This internal reinforcement also has notches on its lateral edges, so that it is crossed at the notches by the injected core, which thus at least partially fills the volume defined between the internal reinforcement and at least one of the external layers.
  • the characteristic reinforcement extends over the entire width of the board, with the exception of the indented areas which connect the volumes located above and below the reinforcement, to allow circulation of the foam expanding during the formation of the core.
  • the reinforcement either in the upper part or in lower part of the nucleus. So when the injection point is below the reinforcement, this foam spreads over the reinforcement, and fills the volume located below the upper protective layer. Conversely, when the injection point is located above the reinforcement, the polyurethane foam spreads and expands passing under the reinforcement, and coming into contact with the sole.
  • the notches made in the reinforcement can be offset longitudinally from one edge to the other of the reinforcement, so that it retains a minimum width sufficient to maintain rigidity desired.
  • the reinforcement is maintained either on one side or the other, which prevents its deformation upwards or downwards.
  • the internal reinforcement can cooperate with the elements of lateral reinforcement at different levels.
  • the reinforcement can rest on a recess forming a shoulder made either in the upper part or in the lower part of the reinforcing element lateral, or even in a groove-shaped recess made on the face internal side element, at an intermediate level.
  • the reinforcement In the case where the reinforcement rests in a recess on an upper part side reinforcement element, it can receive over the contact of the protective top layer.
  • the internal reinforcement can be of very varied natures, and in particular based on a fibrous laminated material, or even a metallic material.
  • the invention also relates to a method of manufacture by injection or molding of a gliding board which comprises so known side reinforcing elements forming all or part of the edges of the board, outer layers forming the sole and the upper layer of protection, as well as at least one internal reinforcement.
  • the method implements a step of in situ injection of chemically reactive components to constitute foam expanding to form the core of the board.
  • the process according to the invention is characterized in that, when the different components of the board in the mold, we block the reinforcement internal in recesses made for this purpose in the reinforcing elements side.
  • This internal reinforcement has lateral notches highlighting communication the volumes defined above and below the reinforcement so to allow a circulation of the foam expanding during the formation of the core.
  • the invention is based on the integration within a gliding board of a characteristic reinforcement, having a geometry whose Figure 1 is an example.
  • Such a reinforcement has a width substantially equal to that of the board, and a length that corresponds to the length in which we want it stretches along the ski.
  • This reinforcement (1) has multiple notches (2, 3) distributed over each sides of the reinforcement, and separated by rectilinear portions (4, 5).
  • these notches (2, 3) have a length L of the order of 15 to 60 mm, and a width l of the order of a few millimeters, typically 2 to 6 mm wide.
  • the notches (2, 3) are arranged on either side reinforcement, and offset from each other so that the width reinforcement is only reduced by the width of a single notch.
  • the reinforcement is put in place as illustrated in Figures 2 and 3.
  • the various elements are placed in a bottom (10) of the mold constituting the lower assembly of the board, namely the sole (11), as well as the edges (12).
  • Different reinforcements can be placed directly above the sole, without interfering with the present invention.
  • the reinforcing elements (13, 14) are arranged above edges (12), at the edge of the mold housing (10).
  • these reinforcing elements also have fins (15) allowing their locking in position in the mold.
  • these reinforcing elements have a recess made at their internal upper corner. This recess (16) forms a shoulder on which the edge (4, 5) of the reinforcement (1) can rest.
  • the notches (3) of the reinforcement (1) define a passage between the volume (20) located below the reinforcement (1) and the volume (21) located above.
  • This upper volume is limited by an upper protective layer (23). It is observed that the mold cover (18) has recesses making it possible to define the bosses (26, 27) on the board. During the injection of the different constituents reacting to form polyurethane foam, these spread by propagating in the volume (20) located below the reinforcement (1), and passing through the different notches (2, 3) in the upper volume (21), so as to push the protective layer (23) against the bottom of the cover of the mold. The reinforcement (1) is held in position because it receives the contact of the upper protective layer at the reinforcing elements (13, 14).
  • the reinforcement (1) is positioned at an intermediate level of the height of the board. To do this, it is placed inside grooves (36) in which the flat portions (4, 5) can be integrated. In this case, when the injection is made either above or below the reinforcement, the passage (37) allows communication between the volumes upper and lower (30, 31), and therefore a homogeneous distribution of the foam polyurethane.
  • the boards according to the invention have the advantage of having reinforcements which are positioned so optimized to the height necessary to give the desired rigidity.
  • the presence of these reinforcements allows the passage of polyurethane foam which allows to realize at the upper face of the board volumes and very varied shapes, without degrading the mechanical performance of the reinforcement.
