Definitions

  • the invention relates to a ski with integrated parts for fixing binding parts.
  • Integrated parts for the fixing of binding parts have already been proposed in the form of screw sleeves arranged recessed in the ski.
  • prefabricated anchoring points or anchoring bearings for binding parts that have already been introduced during ski production are in no way suitable for keeping the binding parts at a precisely defined distance from one another after they have been attached to the ski if the ski undergoes bending during skiing.
  • the measurable lengthening or shortening of the effective distance of the front binding part from the rear binding part when the ski bends leads to a distortion of the triggering forces and can lead to undesired incorrect triggering of bindings.
  • the invention now aims to establish a ski of the type mentioned above with integrated parts To create binding parts with which the torsion properties can be influenced in an adjustable manner in the region of the binding and at the same time the release properties of a binding remain largely unaffected even with different ski deflections.
  • the invention further aims to provide the possibility, in such a device, of connecting the binding elements in a manner to the integrated parts for the fixing of binding parts, which can reliably dampen impacts that act vertically on the ski surface.
  • the ski according to the invention essentially consists in that the ski is rigidly connected to an essentially plate-shaped support body which extends in the longitudinal direction of the ski in an area of the support body lying between the ends pointing in the longitudinal direction of the ski, that the support body is rigid in the outside of the with the ski connected area extending in the longitudinal direction of guide rails or grooves for fixing the binding parts and that the ends of the supporting body pointing in the longitudinal direction of the ski are arranged at a distance from the top of the ski upper belt.
  • the support body Due to the essentially central definition of the support body, the support body itself can be decoupled from forces acting on the ski, and conversely, release forces, such as those which act on the binding parts, do not reach the ski body directly.
  • the decoupling of the binding from the ski which can be achieved in this way makes it possible to define the desired release forces of the binding more precisely, while excessive safety reserves for the release of a binding and thus in many cases premature release of the binding can be avoided.
  • the design is advantageously made such that the support body is located outside the area rigidly connected to the ski Interposition of a damping material is connected to the ski or the upper flange of the ski.
  • a damping material is connected to the ski or the upper flange of the ski.
  • Such an arrangement of the damping material has the consequence that the elasticity and thus the bending behavior of the ski in the longitudinal direction of the ski is in no way impaired, the fixing in the central area ensuring the desired stiffening against torsional forces.
  • a perfect damping of vertical impacts is ensured and a secure and largely indestructible connection is established by fixing the support body in the central area of the support body of the supporting body with the ski.
  • the design is advantageously made such that the support body has projections or recesses in the region of the guide rails or grooves for locking binding parts against displacement in the longitudinal direction of the ski.
  • the design according to the invention can, as is the case in a preferred development, be made in such a way that the support body is arranged below the surface cover layer, in particular below a ski decor surface film. In this way, an integration of the support body and the damping element into the ski construction during manufacture is achieved, which maintains the desired elasticity in the longitudinal direction, while at the same time ensuring a high degree of security against destruction.
  • 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 is particularly well suited for the arrangement of a guide groove for the insertion of binding parts, the binding parts being able to be inserted into the guide groove in the longitudinal direction of the ski, starting from the recessed area of the supporting body.
  • Such Formation of the support body increases the torsional rigidity due to the folds in the area of the profile lowering, the torsion properties being able to be varied to a great extent by the shape and extent of the transverse profiles.
  • the construction can also be 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 with the advantage Ski top belt can be designed as an adhesive.
  • a guide rail is advantageously used to hold binding parts.
  • the middle part of the support body can be screwed to the ski, in particular the upper flange of the ski, such a screw connection 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 into the area of the support body is flat and without pronounced edges, in order to avoid overloading here.
  • the training is advantageously made so that the free ends of the Support body are formed at an acute angle to the ski.
  • Carrier bodies made of metal, in particular aluminum, are advantageously used, and in order to improve the adhesive connection and for easier processing, the design can be such that the carrier 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.
  • 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 is preferably such that the damping material runs essentially transversely to the longitudinal direction of the ski, in particular bores, wherein the recesses can either remain empty or elements, in particular rods, of different hardness and flexibility properties can be inserted into the recesses.
  • 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 supporting body and the damping element which cannot be disassembled during operation, with the risk of detachment of the supporting body or the damping element in the event of strong deflections of the Skis do not exist.
  • 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, with an additional possibility of varying the torsional stabilities in the choice of the profiling of the support body.
  • Glass-fiber-reinforced plastic on the inside of such support 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.
  • Prefabricated anchoring points such as e.g. Screw bushings or the like, for the determination of bindings are integrated.
