Definitions

  • the present invention relates to interpo shock absorbers. between the binding of the boot and the ski, whether alpine or cross-country.
  • shock absorbers all the irregularities of the tracks, which are harder and harder because they are better and better groomed, subject the ski to shocks and vibrations which are transmitted directly to the skier whose skeleton, joints, muscles and tendons are very stressed, hence not only inconvenience but also fatigue which can lead to accidents.
  • too rigid a connection between the skier and the ski is detrimental to good skiing, especially by too great an edge grip which causes untimely braking.
  • a thin elastic blade is mounted between the flat upper surface of the ski and the base plate of the binding. This blade is intended to allow freer flexions of the ski to which the binding gives too much rigidity, and because of its low thickness, cannot play the role of shock absorber to the desired degree.
  • a shock absorber consisting of a layer of elastomer and at least one metal neck is disposed between the flat upper face of the ski and the fixations. Its construction is relatively complex and also raises the boot significantly compared to the ski.
  • the devices which have just been mentioned have at least one major drawback: they are not capable of giving the desired damping effect, or else, mounted above the upper face of the ski, they raise the boot of in such a way that the handling of the sk is significantly affected, and lateral damping is only obtained to a negligible degree. Furthermore, it should be noted that none is capable of being mounted on a ski that does not have a rectangular cross section. -
  • the invention aims to overcome by proposing a partially arranged damping device, between the ski and the binding, in a housing which is clear of the highest part of the profile of the ski at the level of the binding and overflowing. at rest the level of this highest part.
  • FIG. 1 illustrates a first embodiment of the device according to the invention, in cross section with respect to a ski
  • FIG. 2 shows a type of ski with central longitudinal projection to which the embodiment of Figure 1 can be applied
  • FIG. 3 shows in side view a ski boot of the type of that of Figure 2 to which a device according the invention is applied for a front stop and a heel piece
  • FIG. 7 shows a suitable form of shock absorber within the framework of the implementation of the invention
  • a ski 1 is shown in cross section, or in cross section, at the level of a binding 2 for the skier's shoe.
  • a central protruding part 3 of the clearances which may be symmetrical 4, 5 and in which are housed damping buffers 6.
  • damping buffers 6 rest by their lower face on the bottom of the clearances 4, 5 and protrude in height, at rest, the upper level 7 of the projecting central part 3 of the ski 1.
  • On these damping pads 6 is mounted the base plate 8 of the binding 2.
  • the shock-absorbing pads-6 are preferably of rectangular sectio and occupy all or part of the space of the clearances 5, 6 so as to be able to play relatively freely, essentially in the vertical direction relative to the lateral edges of the projection 3. These pads 6 have elasticity properties allowing the damping of sudden mechanical stresses between the ski 1 and the plate 8, and it will be reverted to their own constitution later. Due to their play, they are capable of absorbing both vertical and lateral and longitudinal shocks and vibrations, as well as torsional moments along the three main axes of pitch, roll or yaw. In all cases, the highest part of the ski 1, that is to say the upper level 7 of the projection 3 serves as a stop for limiting the amplitude of the deformations of the buffers 6.
  • the housings or lateral clearances 4, 5 which receive the buffers can be arranged at ⁇ iveaude the binding (s) in the thickness of a conventional ski 2, with rectangular cross section.
  • FIG. 3 shows such a type of ski 1 with central projection 3 fitted with shock-absorbing pads 6 in line with a front stop and a heel piece 2.
  • Figures 4, 5 and 6 relate to another mode of execution of the invention.
  • two lateral damping buffers 6 are not used, but a single central buffer 6.
  • the latter dimensioned accordingly to be able to withstand the same stresses, is disposed in line with the binding 2 in a housing 9 formed in the thickness of the ski 1, preferably being able to play relatively freely along the edges of it. this.
  • the upper surface 7 of the ski serving as a stop for limiting the amplitude of movement now being on either side of the central buffer 6.
  • FIG. 5 shows a ski 1 originally having a longitudinal central hollow profile 9 therefore requiring no care in the thickness of the ski, the necessary housings
  • FIG. 6 illustrates the manner in which such a ski 1 can be equipped with shock-absorbing pads 6 for fixing to the front and heel stop 2.
  • the shock absorbing pads 6 can be made of any material and in any case suitable for the desired effect, the main thing being that, partially housed in clearances relative to the upper face of the ski 1, they only slightly raise, at rest, relative to this surface, the binding of the boot and therefore do not hinder the skier's control over the handling of the skis, as is the case in the most similar solutions that can be found in the prior art.
  • the shock absorbing pads 6 are in the form of blocks, generally parallelepipedal, subject to the ski in the corresponding housing, and to the binding 2.
  • the material used rather than having the pure properties of rubber, is that is to say almost without absorbing part of the energy used in its deformation, will preferably be viscoelastic, therefore having a significant damping coeffi ⁇ cient which can range from a value clearly distinct from zero to a value of .l ⁇ order of 1.2.
  • its hardness will be chosen in a range which can go from 35 to 65 Shore A.
  • Materials allowing the expected result, namely a very reasonable shock absorption without affecting the good conduct of the skis can be chosen from certain polyurethanes, polyisoprene, polyisobutylene and polyisoxylan.
  • the blocks constituting the shock absorbing pads 6 can be directly bonded to the ski 1 in the corresponding clearance and the base plate of the binding 2 can likewise come directly by bonding to the block.
  • FIG. 8 illustrates a possibility of mounting such a shock absorber on a ski 1, the clearance not being shown, the subjugation taking place between the ski 1 and the binding 2 by two layers of glue 12 and 13.
  • FIG. 9 illustrates a mounting by screwing of the plate 10, on the ski 1 and of the binding 2, on the upper plate 11 of the damper pad 6.
  • FIG. 10 shows an embodiment where the pad 6 is glued 12 by its lower plate 10 to the ski 1 and where the binding 2 is screwed onto the upper plate 11 of the sandwich of the pad 6.
  • the shock absorbing pad 6 can, instead of being added later to the ski 1, be mounted directly on the ski during its manufacture.
