Definitions

  • the invention relates to a shock absorber according to the preamble of claim 1.
  • shock absorber is disclosed in EP-A2-0477 314.
  • the socket receiving the insert was either smooth on the outside or provided with a wooden thread and screwed to the blind hole receiving the socket.
  • the socket was received by the ski body over its entire length, which limited the volume of the damping layer.
  • the contact surface of the ski boot was relatively deep compared to the top of the ski.
  • the object of the invention is to further develop the shock absorber of the type mentioned at the outset in such a way that the volume of the damping layers is increased and the distance between the contact surface of the ski shoe and the upper side of the ski can be increased.
  • this object is achieved according to the invention by the features of the characterizing part of this claim. Because the socket partially protruding from the ski body, the same size space is available for the part of the socket in the ski body - provided the dimensions are the same - as for the entire socket according to the parent patent. As a result, the volume of the damping layer can be increased without the ski body having to be additionally weakened by enlarging the bushings.
  • the measures according to the invention also increase the distance of the ski boot from the top of the ski. As a result, skiers' requests in this regard are taken into account in a simple manner.
  • DE-C2 39 25 491 describes a ski in the upper area of which is covered with a cover layer Recess is recessed in which an aluminum plate arranged between two elastomer layers is mounted. With the interposition of bushings, the ski-binding part holding screws are screwed into the aluminum plate. The bushings have plenty of play compared to the aluminum plate and the two elastomer layers. As a result, slight displacements between plate parts and corresponding parts of the ski body can take place with deformation of the elastomer layers, so that the ski can deflect or deflect without the stiffening forces of the binding and the ski boot being counteracted to any significant extent.
  • This design is complicated in that the aluminum plate and the two elastomer layers have to be arranged inside the ski.
  • the described embodiment can therefore only be used with a ski that has been specially manufactured in a separate process.
  • the recess causes a considerable weakening of the ski cross-section, particularly in the extremely endangered area carrying the ski binding parts, which adversely affects the strength of the ski.
  • plugs made of a viscoelastic material are embedded in the core of a ski, which plugs are used to hold metal bushings that receive the ends of the fastening screws intended for the ski binding.
  • the plugs can be connected to a single element by a plate. However, they can also be manufactured individually and then placed in cylindrical holes in the ski core.
  • the measure of claim 2 saves material in the manufacture of the socket, and it also creates the possibility of varying the position of the socket relative to the top of the ski upwards or downwards.
  • the subject of claim 3 increases the displacement of the base plate of the ski binding part downward in the event of vibrations.
  • the features of claim 4 also allow damping of the vibrations occurring in the ski body.
  • the measure of claim 5 ensures that the ski bends when driving through hollows and humps, and furthermore in both cases also a springback without increasing the ski preload.
  • the damping properties of the vibrations occurring in the longitudinal direction of the ski can be improved or controlled by the subjects of claims 6, 10 and 11.
  • the features of claim 7 ensure secure storage of the cover plate on the ski.
  • Claims 8 and 9 facilitate the relative movement between the ski binding or the cover plate and the ski.
  • the subjects of claims 12 and 13 bring a weight saving of the shock absorber with it.
  • FIG.1 is a vertical longitudinal central section through a first and Fig.2 through a second embodiment.
  • FIGS. 3 and 4 Another embodiment is shown in FIGS. 3 and 4, FIG. 3 showing a section along the line III-III in FIG. 4 and FIG. 4 a section along the line IV-IV in FIG. 5 shows a further variant similar to FIG. 3.
  • 6 shows an embodiment with a divided cover plate, similar to FIG. 4.
  • FIG. 7 illustrates a detail of the cover plate on a larger scale.
  • 8 and 9 each show a variant of the cover plate in longitudinal section and cross section.
  • 1 denotes a ski in which vertical blind holes 1b are left free.
  • a bushing 2 with a wooden thread 2a is screwed into each of these bores 1b.
  • the socket 2 carries a flange 2b with which the socket 2 rests on the upper side 1b of the ski 1.
  • the flange 2b is formed in one piece with the bush 2.
  • a bottom 2c is screwed into the lower end of the socket 2.
  • the the upper end of the socket 2 is closed by a cover 2d which is integral with the socket 2.
  • the socket 2 which is smooth on the inside, there is an insert 4, 5, 6 which consists of a high-strength layer 4 of metal or of a GRP fabric laminate and of a layer 5 of elastomer material arranged above this and of a layer layer 6 arranged under the high-strength layer 4 consists of elastomeric material.
  • a spacer sleeve 7 is supported on the metal layer 4 and passes through the cover 2d of the socket 2 with play. The spacer sleeve 7 protrudes about 3mm beyond the upper end of the socket 2 and serves to support a base plate 8 of the associated ski binding element.
  • the base plate 8 is penetrated by screws 9 which are each guided in a spacer sleeve 7 and which are screwed into the respective metal layer 4 with their lower end. In this way, the ski binding part is elastically supported relative to the ski 1. This dampens shocks that occur in the vertical direction on the ski 1.
  • the invention according to a further embodiment according to FIGS. 3 and 4 provides that a damping layer 11 protected by a cover plate 10 is arranged on the upper side 1a of the ski 1, the cover plate 10 being at least on one End 10b is held on the ski 1 by means of screws 3.
  • the other end 10c of the cover plate 10 is guided relative to the ski 1 by a hold-down device 13, which is also fastened on the ski 1 by means of screws 3.
  • the cover plate 10 has elongated holes 10a, which extend in the longitudinal direction of the ski. In the rest position of the ski 1, the bushes 2 are located in the longitudinal center of the elongated holes 10a.
  • the cover plate 10 is secured against lifting up by the base plates 8 of the individual ski binding parts. Securing against lateral displacement transversely to the longitudinal axis of the ski takes place through the elongated holes 10a guided on the bushings 2.
  • the slidably guided end 10c of the cover plate 10 can, as shown in FIG. 7, be a body 15 made of rubber-elastic Be assigned material that is supported on the one hand on a transverse wall 10d of the cover plate 10 and on the other hand on a piston 16.
  • This piston 16 carries a threaded spindle 14 which is screw-mounted in a ski-fixed abutment 13a formed in one piece with the hold-down device 13.
  • This configuration makes it possible for the body 15 to be freely displaceably guided in a predetermined region between the piston 16 and the transverse wall 10d of the cover plate 10, and for the prestressing of the body 15 to be between zero and a limit value by means of the threaded spindle 14 in a subsequent region is continuously adjustable.
  • a plate 12 made of a material with good sliding properties e.g. made of polytetrafluoroethylene (known inter alia under the brand name "Teflon"), or the end of the cover plate 10 is coated with such a material.
  • Teflon polytetrafluoroethylene
  • the bushing 22 in its upper region with a (metric) thread 22e and to form the flange 22b as a ring nut.
  • This flange 22b is disc-shaped and provided with an internal thread 22f.
  • cover plate 310 has stiffening ribs 310i running in the transverse direction in its upper height section, which lie on the damping layer 311 and form cells 310j with this.
  • This can reduce the overall weight of the shock absorber, but only a relatively small loss of damping has to be accepted, since the cells 310j also contribute to the damping of the ski 301.
  • This sandwich construction is illustrated in Fig.8.
  • longitudinal grooves 410k in the underside of the cover plate 410, for example by milling.
  • Fig. 9 shows this variant.
  • the invention is not tied to the exemplary embodiments shown in the drawing and described above. Rather, various modifications are possible without leaving the scope of the invention.
  • the other end of the cover plate can also be held on the ski.
  • an eccentric can also be used for the longitudinal adjustment of the body made of rubber-elastic material, which is rotatably mounted on a vertical axis in the abutment.
  • the abutment can also be designed as a separate component from the hold-down device and attached to the latter.
  • a plate made of a material with good sliding properties is arranged not only between the base plate of the ski binding part and the cover plate, if appropriate also between the free end of the cover plate and a hold-down device, or that one of these surfaces is arranged to reduce undesirable frictional forces is coated with such a material.
  • a similar measure can also be provided between other components which are designed as sliding bodies.
  • the course of the ribs according to FIG. 8, similar to that shown in FIG. 9, can run in the longitudinal direction of the cover plate; or the grooves according to FIG. 9, similar to that shown in FIG. 8, can run in the transverse direction of the cover plate.
