Definitions

  • the invention relates to the combination of a vibration damping device with an alpine ski according to the preamble of claim 1.
  • a vibration damping device in a vibration damping device according to document WO 83/3360 or EP-B1 0 104 185, it is known to have a damping plate, on which the two ski binding parts, namely a toe piece and a heel holder, are fixed with one end section and with the other end section slidably to store on the ski.
  • the holding plate is arranged with the interposition of a damping layer on the top of the ski. Furthermore, the two end portions of the holding plate, which are used for storage, are bent toward the top of the ski.
  • the end section of the holding plate connected to the ski has bores for receiving holding screws, whereas the sliding end section of the holding plate is provided with elongated recesses for this purpose.
  • a cross-sectionally U-shaped guide and damping cap with screws arranged in it is placed on the holding plate. These screws engage with the interposition of one plastic element each in the elongated recesses of the bent end section of the holding plate.
  • the plate disclosed in this document has a supporting function for the two ski binding parts, the arrangement of the two retaining screws in the damping cap not directly engaging the two fastening screws with the cranked end section of the retaining plate.
  • Document FR-1,467,141 discloses the design of a multi-layer ski, in which the fastening screws penetrate elongated holes in the layers held together, but the known embodiment does not represent a combination of a vibration damping device with an alpine ski.
  • FR-A-2,409,776 discloses various elastic bearings for fastening screws for a plate on a ski, but without disclosing any details that go beyond the known and already considered prior art.
  • the invention has set itself the goal of defining a damping device or damping devices of the type mentioned on the ski in such a way that they have no additional, unplanned change or influence the bending characteristic of the ski and a simplified structure, a quick and inexpensive Allow assembly and an arrangement secured against environmental influences.
  • the aforementioned EP-B1 0 188 985 further teaches that the damping device is centered in one of the three zones, which are at a distance between 10 and 20%, 65 and 75% and 85 and 97% of the load-bearing length from the end of the ski , whereby the length of the ski minus the bent-up sections of the shovel and ski end is referred to as the supporting length.
  • the damping device according to the invention in addition to the simple construction and quick assembly, enables particularly favorable damping properties to be achieved.
  • a particularly advantageous embodiment results from the embodiment according to the features of claim 2, since differently designed front jaws can be used in this way.
  • the feature of claim 3 reduces the risk of getting caught when the skis cross over while driving.
  • the features of claim 4 aim in a similar direction.
  • the measures contained in claim 5 prevent the ski from pretensioning or stiffening, while at the same time determining the thickness of the damping layer gives the designer a wider choice. Furthermore, larger tolerances are made possible during manufacture.
  • FIG. 1 shows a plan view of a ski with a ski binding and a vibration damping device according to the invention
  • FIG. 2 shows a section along the line II-II in FIG. 1 on a larger scale
  • FIG. 3 shows a detail of the damping device
  • FIGS. 4 and 5 each a section along the line IV-IV or VV in Figure 2 for two configurations of the cover
  • Figures 6 and 7 a variant of the front portion of the damping device, during assembly or in the assembled state, in each case in longitudinal section
  • 8 shows a detail of Figure 6 in plan view.
  • FIGS. 9 and 10 show two further types of fastening of the damping device when assembled with a toe piece or with a support device for a toe piece.
  • a toe piece 2 shown only with its outlines and a heel holder 3 of a ski binding also only outlined with its outlines.
  • the design and arrangement of these components on the ski are known per se and do not constitute an object of the present invention.
  • a damping device 10 forming the subject matter of the invention, which is fastened on the top of the ski 1a in a manner to be described in more detail.
  • damping device 10 The entire structure of the damping device 10 can be seen better and on a larger scale from FIG. in which the damping device 10 is shown.
  • a layer 7 of visco-elastic material is glued to the top 1a of the ski 1 by means of an adhesive tape 8, which preferably consists of acrylic foam, and covered by a cover 9.
  • an adhesive tape 8 which preferably consists of acrylic foam
  • the visco-elastic layer 7 can be an elastomer.
  • the adhesive tape consisting of acrylic foam sticks on both sides, namely to the layer 7 and together with this to the top 1a of the ski 1.
  • the cover 9 is only with its front and rear end sections 9a and 9b on the top 1a attached to the ski 1, in the present embodiment in the rear end section 9b by means of two screws 5 and with its front end section 9a slidably supported by a bracket to be described in more detail below.
  • This holder has a retaining screw 6, which is screwed into the ski 1 while leaving a thread-free shaft section 6b free. With this free shaft section 6b, the holding screw 6 passes through a projection 9c which is approximately U-shaped in plan view, which is formed on the base of the cover 9 and is oriented with its two legs pointing towards the rear end section of the cover 9.
  • the configuration of the front end section 9a with the U-shaped extension 9c can best be seen in FIG. 3 when the cover 9 is not in use.
  • the damping device 10 is positioned on the ski 1 in an area of the ski 1 which adjoins the front jaws 2.
  • the configuration is such that the height H of the damping device 10 is smaller than its width B (FIG. 4), preferably 10 to 40% of the width B is. It has proven to be particularly advantageous if the length of the damping device 10 is less than 200 mm, preferably not more than 150 mm.
  • the two side surfaces 9d of the cover 9 or the tangents t placed thereon run at an acute angle of 10 to 80 °, preferably 40 to 60 °, to the base 9e of the damping device 10.
  • the cover 9 with its side surfaces 9d rests loosely on the upper side 1a of the ski 1, possibly with a play s to it.
  • 4 shows the embodiment in which the two side surfaces 9d of the cover 9 lie loosely on the upper side 1a of the ski 1.
  • FIGS. 6 to 8 Another type of fastening of the front end section 9'a of a variant of the cover 9 'is shown in FIGS. 6 to 8. It can be seen in FIGS. 6 and 7 that in this embodiment the front end section 9'a of the cover 9' is directed towards Top 1'a of the ski 1 'is bent and has an elongated hole 9'c in the area of the holding screw 6', the elongated dimension of which is larger than the diameter of the thread-free screw shaft 6'b, whereas the width of the elongated hole 9'c is less than the diameter of the screw head is 6'c (cf. in particular FIG. 8). The correct position of the retaining screw 6 'is initially determined during assembly.
  • the cover 9 'with its slot 9'c is placed in the center of the hole provided for the retaining screw 6', then this is inserted and screwed onto the ski 1 '.
  • the holding screw 6 ' is inserted and screwed in when the cover 9' is in a state when its cover 9'g has not yet been inserted into the cover 9 ', see FIG. Figures 6 and 8, wherein 8 shows a top view of the front end portion 9'a of the cover 9 '.
  • the cover 9'g is then inserted into a longitudinal slot 9'f of the cover 9 ', so that the inside thereof is protected against snow, ice, etc. (see FIG. 7).
  • FIGS. 9 and 10 show two different types of fastening of the rear end section 9b, 9 ′′ b of the cover 9.9 ′′ in connection with the front jaw 2.2 ′′, FIG. 9 showing a detail of FIGS. 1 and 2 on a larger scale and Figure 10 is a modification on the same scale.
  • the damping device 10 ′′ is fastened directly on the upper side 1a of the ski 1 with the fastening screws 4 ′′ of the toe piece 2.
  • a holding device 2''a for the toe piece 2 '' on the other hand, it is fastened together with the fastening screws 4 '' of this toe piece on the upper side 1a, 1''a of the ski 1,1 ''.
  • the invention is not restricted to the exemplary embodiment shown. Modifications are well within the scope of the invention. This means that other visco-elastic materials can also be used - also in conjunction with another adhesive tape. Design and slidable mounting of the front end portion of the cover of the damping device may differ from the configuration described.
