Definitions

  • the invention relates to the field of sliding boards on snow, such as skis, surfboards or the like. It relates more particularly to a method allowing the manufacture of boards incorporating the additional rigid elements present on its upper face.
  • a gliding board has a central core under which there is a lower assembly mainly comprising a gliding sole, edges and one or more lower reinforcements.
  • the core is covered with a top assembly that incorporates a top layer of protection and decoration and, in most cases, one or more reinforcing layers, which may be metal reinforcements or fibrous reinforcements impregnated with a resin mechanizing. These reinforcements are intended to increase the rigidity of the board and give it mechanical properties of flexural strength.
  • the kernels of the skis are made by injecting different components reacting in situ inside a mold, to cause the formation of a polyurethane foam constituting the core.
  • the core comes to press the upper assembly under the mold cover to give it its final shape.
  • the upper assembly comprises several layers and in particular a fibrous reinforcement, it is necessary to join, for example by gluing, this reinforcing layer under the upper layer of protection and decoration which itself comes into contact with the mold cover.
  • skis or more generally gliding boards, in which a pre-made core is used are also known.
  • the core is made by a specific machining or molding operation, and is then assembled in a mold with the upper and lower assemblies.
  • the upper face of the board has additional elements for decorative functions or technical functions such as the attachment of various elements, including damping.
  • a problem therefore generally arises to arrange these different additional elements on the upper assembly, in a manner that allows the establishment of this upper assembly in the mold while maintaining the desired position of these additional elements on the board. Indeed, the establishment by gluing can not be satisfactory insofar as the risk of detachment and tearing of these additional elements would be too great, when they are exposed to shocks during the subsequent use of the board. This is why these additional elements generally have an apparent portion located on the upper face of the board, and a through portion, which extends under the upper protective layer.
  • One of the objectives of the invention is to allow easy and firm positioning of the additional elements on the upper assembly during the manufacturing process, while ensuring a very strong anchoring in the structure of the board.
  • the invention therefore relates to a gliding board comprising an upper assembly comprising at least one layer, and in particular an upper protective layer.
  • This board also includes at least one rigid element, metallic or otherwise, partially visible on the upper face of the board.
  • This rigid element has an apparent portion which rests on the upper protective layer, and one or more through portions which extend below the visible portion, passing through the upper assembly.
  • this rigid element comprises anchoring portions, which are located below and at the lower face of one of the layers of the upper assembly. These anchoring portions form a stop which cooperates with the lower face of this layer, so as to grip all or part of the layers of the upper assembly between the lower face of the apparent portion of the rigid element and this stop. In this way, it prevents the displacement of the rigid elements relative to the upper assembly.
  • the invention consists in firmly locking the rigid element, without any possibility of deflection, by using an anchoring portion which comes into contact with the lower face of the upper assembly.
  • the upper assembly is sandwiched between the characteristic anchoring portions and the outer portion of the additional element, which is pressed directly against the upper face of the board.
  • the anchoring portions are no longer embedded in the core of the core, in the case where it is injected, so that the risks of tearing are greatly reduced.
  • the anchoring portions forming the abutments can be made in different ways, depending on the geometry of the additional elements, and the tear resistance they must present in the context of the normal use of the board.
  • the anchoring portions may be formed by the ends of the through portions, which are curved substantially parallel to the lower face of the upper assembly. These curved ends come into contact with the lower face of the upper assembly and prevent any movement of the additional element in a direction perpendicular to the upper assembly.
  • the anchoring portions may be formed by locking members mounted on the through portions, and coming into contact with the lower face of one of the layers of the upper assembly.
  • additional members are placed on the through portions, so as to flush under a layer of the upper assembly, and prevent the displacement of additional rigid elements relative to the upper assembly.
  • these locking members may be clamping washers, pins and other members which pass through the through portions extending parallel to a layer of the lower face of the upper assembly coming from the tangenter.
  • the anchoring portion or portions of the additional element can sandwich all or part of the upper assembly.
  • the anchoring portions can come into direct contact with the underside of the top layer of protection. This mode is particularly suitable for additional elements that are not mechanically stressed.
  • the characteristic anchoring portions come into contact with the lower face of the upper protective layer, it is also possible to cover these anchoring portions, and the remainder of the upper protective layer, with a fibrous reinforcement .
  • the upper assembly may also include one or more fibrous reinforcement layers which are traversed by the through portions.
  • the anchoring portions come to bear directly under these fibrous reinforcement layers, and maintain the same with respect to the upper protective layer.
  • the fibrous reinforcements may be impregnated with a mechanizing resin intended to polymerize during the injection, or else be stiffened by a previously polymerized mechanizing resin.
  • the upper assembly includes complementary layers, such as for example one or more layers based on deformable polymeric material, in some cases having viscoelastic properties, in order to contribute to the damping of the board.
  • the through portions of the rigid additional element may be constituted by spikes, advantageously self-piercing, which allow to pass through the upper protective layer, and possibly the fibrous reinforcement without the need for a preliminary drilling operation.
  • the implementation of these elements can be likened to the installation of rivets.
  • the rigid additional element may have, on its face in contact with the upper protective layer, a prominent region encircling the through portions. In this way, this protruding portion partially penetrates the deformable material of the upper protective layer. It thus constitutes a watertight barrier with respect to the possible rise of the resin reinforcements or core through the passage openings of the through portions.
  • These possible resin lifts are thus circumscribed under the rigid additional element, and are not likely to overflow on the upper face of the board.
  • the resin lifts can also be avoided by placing a waterproof film, present under the anchoring portions, and preventing any passage of material through the holes through which the through portions pass.
  • the additional rigid element can take on a variety of shapes and have various functions.
  • this rigid element is partially embedded in the upper protective layer. This is particularly the case when this additional element is a decorative member which it is desired that it is flush only at the upper face of the board.
  • the apparent portion of this rigid element may comprise at least one prominent zone, such as a snap, hook or other type, capable of ensuring the attachment of an accessory to the board.
  • the apparent portion of the rigid element may be surmounted by a member of polymeric material, of the compressible foam type. This foam may for example be compressed by the pressure exerted during the molding operation. The resilience of the material causes that after demolding, the foam re-increases in volume to form a prominent and compressible portion on the upper face of the board. In particular, it may be zones making it easier to grip the board.
  • the additional element of accommodating on its upper face the abutment or heel of a safety fastener, or more generally any member capable of undergoing great efforts. amplitude.
  • the anchoring of the additional element just under the reinforcement of the upper assembly improves the strength and tear resistance, which are imperative qualities for this type of functions.
  • the rigid additional element (1) illustrated in Figure 1 consists mainly of a plate (2) forming the visible portion of the additional element, and which can support on its upper face, different mechanisms or holes not shown , in particular for the implementation of the elements of the security fastener for example.
  • This apparent portion (2) has on its underside four through portions (3) in the form of platelets extending perpendicularly to the plate (2).
  • the through portions (3) are arranged in two spaced pairs, and each comprise a bore (4) for receiving the anchoring portions.
  • the plate (1) is intended to be secured to the upper assembly (10) constituted by the illustrated form of the upper layer of protection and decoration (11) and a layer of fibrous reinforcement (12), typically based on a glass yarn fabric coated with a thermosetting resin. Openings (14) are made both in the upper protective layer (11) and the fibrous reinforcement (12) so as to allow passage of the through portions (3).
  • the anchoring portions (16) formed by pins penetrate the openings (4) present in the anchoring portions (3) so that these pins (16) are flush with the lower face (15) of the reinforcing layer (12).
  • the reinforcing layer (12) is locked between the upper protective layer (11) and the pins (16), and can not move unexpectedly.
  • the positioning of the pins, and more generally anchoring portions can be done by ensuring a slight pressure on the crossed layers, so as to take advantage of a compression of these layers to prevent any unexpected movement of the anchoring portions after their installation. This eliminates any play between the various layers, and especially between the upper face of the board and the apparent portion of the additional elements.
  • the precise position of the openings (4) in the through portions must be precise enough to avoid as much as possible the passage of foam between the underside of the upper assembly and the pins. This prevents the risk of having above the pin, a quantity of foam of the core which is a compressible area, source of play later.
  • pins that pass through not one, but several through portions, or else various form of locking members, as long as they come into contact at least over part of their length. with the reinforcing layer (12) to prevent movement.
  • the upper assembly (10) on which the rigid additional element (1) is installed can be put into place in a mold (30) comprising a mold bottom (31) accommodating the lower assembly (32).
  • the upper assembly (10) and the additional rigid member are pressed against the mold cover (33) upon expansion of the core foam (36).
  • the additional rigid element (40) comprises an apparent portion (42) under which extend the through portions (43) formed of peaks whose ends (44) are self piercing.
  • the underside (45) of the exposed portion (42) has a prominent region (46) extending peripherally surrounding the through areas (43).
  • the introduction of the additional element (41) is done by drilling the upper protective layer (11).
  • the tips (43) are folded laterally under the underside (18) of the upper protective layer (11).
  • the protruding peripheral zone (46) circumscribes the region in which the tips (43) have formed openings (48) in the upper protective layer (11). Possible lifts resin at these openings are thus blocked and are not likely to appear on the visible part of the board.
  • a reinforcing layer (49), in particular fibrous, can then be glued or assembled by any means under the upper protective layer (11), so as to form an upper assembly easily manipulated without risk of falling additional elements.
  • the invention allows a place on a board of additional rigid elements by a method that facilitates handling operations of the upper assembly. Indeed, its additional elements pinch the upper assembly, which ensures a precise and definitive positioning, while maintaining the reinforcement layers. In addition, these additional rigid elements are anchored closer to the reinforcing layers, which ensures them good resistance to tearing.
