Definitions

  • the invention relates to a ski with a damping element for damping shocks acting transversely to the longitudinal direction of the ski in the region of a ski binding, with a support body for at least one layer of damping material, in particular elastomeric damping material, arranged between the support body and the ski.
  • a damping element for a ski which can be fixed on the top of a ski and should be able to allow damping in the longitudinal direction of the ski.
  • a metallic carrier plate is interposed by means of screws with an elastomeric damping layer on the upper side, the fixing having to be displaceable on at least one side in order to prevent the screw connection from shearing when the ski bends.
  • damping is transverse to the longitudinal direction, i.e. in a direction essentially perpendicular to the surface of the ski with such a design is not aimed at and only achieved incompletely.
  • the bending behavior of the ski is influenced by damping in the longitudinal direction of the ski.
  • a noteworthy influence on the torsion properties cannot easily be achieved with regard to the sliding connection of such a damping element with the surface of the ski.
  • plate-shaped elements In order to improve the steerability of skis, plate-shaped elements have already been proposed, which allow a certain degree of adjustability in their inclination transverse to the longitudinal axis of the ski. Naturally, such designs also have no influence on the torsional properties of a ski and are intended to reduce the risk of canting when the body is shifted to the side.
  • the invention now aims to develop a ski of the type mentioned in such a way that a perfect damping of vertical impacts transverse to the longitudinal axis of a ski is achieved and, at the same time, the torsional behavior of the ski can be set within wide limits. Furthermore, the construction according to the invention is intended to achieve a connection of such a damping element to the ski that is as simple and reliable as possible, which prevents separation of the damping element from the ski with certainty even in the event of hard impacts and deflections of the ski.
  • the training according to the invention essentially consists in the fact that the support body is rigidly connected to the upper belt of the ski and in front and behind in a central area between its front and rear ends lying in the longitudinal direction of the ski or directly or via an intermediate layer made of glass fiber reinforced plastic middle area is connected to the top of the ski with the interposition of the damping material.
  • the fixing in a central area can be kept free of shear forces when the ski bends, so that a secure anchoring and fixing of the damping element is guaranteed even if the ski bends excessively.
  • the support body can advantageously have profiles that run transversely to the longitudinal direction of the ski, the design being made in a particularly advantageous manner so that the support body in the central region is one of the Thickness of the damping material has a corresponding recess and is rigidly connected to the ski in the recessed area.
  • Such a lowering of the profile in the central area enables a perfect connection of the support body to the upper flange of the ski, the damping material likewise being able to be at least partially embedded in the surface of the ski.
  • Such a design of the support body increases the torsional rigidity due to the folds in the area of the profile lowering, the shape and extent of the transverse arranged profiles the torsion properties can be varied to a large extent.
  • the construction is advantageously made such that the recessed area of the support body is filled with a correspondingly pressure-resistant filler, the rigid connection of the support body to the Ski top belt can be designed as an adhesive.
  • the middle part of the support body can be glued and screwed to the ski, in particular the upper flange of the ski, such screwing not having to absorb shear forces when the ski bends.
  • a uniform design of the surface with simultaneous additional securing of the damping element is ensured in that the support body is arranged below the surface cover layer, the design advantageously being such that the support body is arranged flush with the surface layer or film in a recess on the top of the ski is.
  • the surface film in front of and behind the carrier body is advantageously cut or cut transversely to the longitudinal direction of the ski, with Advantage of the transition from the undamped areas of the ski to the area of the damping plate is flat and without pronounced edges, in order to avoid overloading here.
  • the design is advantageously made such that the free ends of the support body are formed at an acute angle to the ski.
  • Carriers made of metal, in particular aluminum, are advantageously used, with the aim of improving the Adhesive connection and, for easier processing, the design can be made such that the support body is rigidly connected to the upper chord with the interposition of at least one layer of glass fiber reinforced plastic.
  • the entire inner surface of the support body can have a layer of glass fiber reinforced plastic, so that a simple adhesive bond to the damping material is also possible as a result.
  • the design can advantageously be made such that damping elements of different hardness or rigidity are arranged next to one another in the longitudinal direction of the ski, transversely to the longitudinal direction of the ski, in which If the damping elements arranged next to one another in the longitudinal direction of the ski can be welded or glued in a particularly advantageous manner to the layer made of glass fiber reinforced plastic on the inside of the carrier body.
  • the thickness of the damping element should advantageously be between 2 and 12 mm.
  • the design according to the invention allows the elastic movement of the ski to the full extent without being impaired by the damping element and leads to a rigid fixing of the damping element which cannot be disassembled during operation, the risk of detachment of the damping element not being present in the event of strong deflections of the ski.
  • a reproducible, reliable bond can only be ensured in the case of the determination already made during manufacture, in which the rigid bond is to be made directly to the upper belt of the ski.
  • the desired torsional properties can be set by using different hardnesses of damping elements running in the longitudinal direction of the ski, with an additional possibility of varying the torsional stability in the choice of the profiling of the carrier body being available.
  • Glass-fiber reinforced plastic on the inside of such carrier bodies can on the one hand facilitate the secure gluing and on the other hand take over the function of reinforcement laminates, which can likewise increase the torsional stability and reduce the risk of tearing off bonds which can be attached to such damping elements.
  • the design is preferably such that the damping material has recesses, in particular bores, running essentially transversely to the longitudinal direction of the ski, the recesses either being able to remain empty or elements, in particular rods, in the recesses.
  • different hardness and flexibility properties can be used.
  • Prefabricated anchoring points such as screw bushings or the like, can be integrated into the carrier body for the fixing of bindings.
  • FIG. 1 shows a partial perspective view of a ski according to the invention
  • 2 shows a section along the line II-II of Figure 1
  • 3 shows a section along the line III-III of Figure 1
  • 4 shows a section along the line IV-IV of Figure 1
  • 5 shows a section through a modified embodiment in a representation analogous to FIG. 3
  • 6 shows a section through the embodiment according to FIG. 5 in a representation analogous to FIG. 4
  • FIG. 7 in a representation similar to FIG. 1, a modified embodiment of a ski according to the invention with recesses in the damping material for adjusting the flexibility.
  • a ski 1 to 4 show a ski 1, the top of which is covered by a surface cover layer, for example a ski decor surface film 2.
  • a supporting body 3 for example made of aluminum, is provided for damping shocks acting transversely to the longitudinal direction of the ski, which is directly rigidly connected to the ski in a central area 4, for example by gluing and optionally by an additional screw connection is.
  • the areas of the support body 3 adjoining the central area 4 rigidly connected to the ski 1 connect to the ski with the interposition of damping material, in particular elastomeric damping material 5.
  • the stepped or recessed area 4 of the rigid connection of the support body to the ski 1 is filled with a correspondingly pressure-resistant filler 6.
  • the depth of the offset region of the profile forming the support body 3 corresponds essentially to the height or thickness of the damping material 5.
  • gluing or rigid connection of the support body 3 to the ski 1 and in particular to its upper flange 7 can take place with the interposition of a layer made of glass fiber reinforced plastic.
  • a continuous GRP layer 8 is additionally provided on the surface of the support body 3 facing the ski 1 in the embodiment according to FIGS. 5 and 6.
  • damping elements of different hardness can be arranged next to one another transversely to the longitudinal direction of the ski, as is indicated in FIGS. 4 and 6 by the outer damping elements 5 and inner damping elements 9.
  • the free ends 10 of the support body 3 run at an acute angle to the surface of the ski 1 or its upper flange 7 and end in the unloaded position of the ski at a short distance from the surface of the upper flange 7.
  • the surface cover layer is cut or cut directly in front of and behind the support body transversely to the longitudinal direction of the ski, as is schematically indicated by 11.
  • recesses or bores 12 are provided in the damping material 5 which run essentially transversely to the longitudinal direction of the ski and which, depending on their number and arrangement, result in an increase in the elasticity of the supporting body 3 and the damping material 5.
  • rods 13 of corresponding cross-section can be inserted into the recesses or bores 12, with the use of bars of different material properties adapting to the Desired flexibility behavior of the damping material 5 can be achieved.
