Definitions

  • the present invention relates to a ski binding for mounting on a ski with two ski binding parts, namely a toe piece and a heel piece, at least one of which is mounted with longitudinal movement to a limited extent in the longitudinal direction of the ski, the ski binding parts by means of a length-stable connecting element which runs at a distance from the top of the ski are connected to one another and the connecting element can be firmly connected to the ski in the region of one of the ski binding parts, the other ski binding part having a ski-fixed guide rail for longitudinal guidance of the front or heel cheek.
  • a ski binding of this type has become known, for example, from AT-PS 389 453.
  • the connecting element is a steel band, which is attached with the front end via a row of holes on the ski-mounted front jaw and has a latching part at the rear end which can be locked with a counter-latching of the heel jaw.
  • the latching part is mounted in a longitudinally oriented recess in the guide rail attached to the ski.
  • the connecting band has been provided with an elastic pad in order to dampen the impacts that occur on the skier during the journey.
  • the elastic pad is not connected to the top of the ski in order to maintain the possibility of unimpeded bending of the ski.
  • a spacer is arranged in the middle section of the length-stable band, by means of which the distance between the length-stable band and the ski can be predetermined. This spacer serves to influence the bending tension of the ski and thus to further improve the skiing properties in the sense of greater ease of turning.
  • a holding device for the front or heel jaws in which both the front and the heel jaws are connected to the top of the ski with the interposition of one holding body each.
  • the holding bodies are attached to the ski via claws and have raised sections which are connected to one another via webs.
  • WO 93/12845 describes a ski binding which is connected to the ski via a damping and month element.
  • the damping and mounting element has a hard top plate, which is connected via a damping layer to the top of the ski in such a way that both the front and the rear end region of the top plate can be moved in the longitudinal direction.
  • the front and heel cheeks are attached to the top plate.
  • the front and heel jaws of the ski binding are each attached to a mounting plate which is connected to the top of the ski via a damping layer, the two mounting plates being connected to one another by means of a band running in the longitudinal direction of the ski, which is attached to the ski approximately midway between the front and heel cheeks.
  • a disadvantage of this ski binding is, among other things, that the power transmission to the ski is delayed by the damping position and the skier therefore experiences an insecure feeling.
  • the toe piece is attached to the ski via a holding body.
  • a connecting plate extends between the front and heel cheeks and is attached to the ski at its rear end.
  • the heel shoe is attached directly to the connection plate.
  • recesses are provided in the connecting plate, through which protrusions of the holding body protrude.
  • the connecting plate is connected to the top of the ski via a damping layer.
  • the object of the invention is to create a ski binding in which, while maintaining known front and heel cheeks, on the one hand simple and effective attachment of the binding to the ski is possible, and on the other hand the advantages of new developments, such as length compensation or damping this longitudinal movement can be used. Furthermore, the possibility should be created to provide for influencing the bending properties of the ski if necessary.
  • the connecting element is designed as a damping plate, one with the top of the ski connected damping layer and at least one recess assigned to the front jaw or the heel jaw, the ski binding parts being securely connectable to the ski via at least one holding body each and the holding bodies pushing through the recesses of the damping plate with play on both sides in the longitudinal direction of the ski.
  • an elongated damping plate is arranged in the binding area, which has at least in the front and rear end area a damping layer connected to the top of the ski and at least one each to the front jaw or has a recess associated with the heel cheek, the ski binding parts being securely connectable to the ski via at least one holding body each and the holding bodies penetrating the recesses with play on both sides in the longitudinal direction of the ski.
  • Both variants of a ski binding according to the invention thus make it possible to additionally control the length compensation function both in the area of the toe piece and in the area of the heel piece by means of a damping layer which is integrated in a damping plate which, as stated above, can also take over the function of the connecting element.
  • the recesses in the damping plate enable the ski binding to be installed quickly and easily without having to forego the advantages of controlled length compensation.
  • FIGS. 1 and 2 in which a ski binding according to the invention is shown in a first embodiment.
  • the ski binding shown has two ski binding parts, indicated by dashed lines, namely a front jaw 1 and a heel jaw 2, which can be fastened to a ski 5 via holding bodies 3a, 3b, 3c, 3d or 4a, 4b, 4c, 4d.
  • the holding bodies 3a, 3b, 3c, 3d, 4a, 4b, 4c, 4d each have a plurality of bores arranged one behind the other in the longitudinal direction for fastening the front and heel cheeks in a plurality of different longitudinal positions. In the illustrated embodiment, three different longitudinal positions are provided for the front jaw and six for the heel jaw.
  • the holding body 3a, 3b, 3c, 3d assigned to the front jaw 1 and the holding body 4a, 4b, 4c, 4d assigned to the heel jaw 2 are connected to one another by means of connecting straps 6a, 6b, 6c, 6d and 7a, 7b, 7c, so that for the Front jaws 1 and heel jaws 2 each form an integral fastening block 8 or 9.
  • These mounting blocks 8, 9 can be screwed to the ski 5 on the one hand by means of (not shown) mounting screws for the ski binding parts 1, 2 with the front and heel cheeks.
  • these fastening blocks can, however, also be fastened separately to the upper side 5a of the ski 5 via one or more of the connecting straps 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7c or by means of suitable claws (not shown here).
  • the fastening screws for the ski binding parts 1, 2 only have to be screwed into the holding body and no longer into the ski.
  • the toe 1 of the ski binding according to the invention is rigidly connected to the ski 5 in the exemplary embodiment shown, whereas the heel 2 is arranged to be longitudinally displaceable.
  • the heel jaw 2 is held in a guide rail 10 which is fastened to the ski 5 via the holding bodies 7a, 7b, 7c, 7d.
  • a damping plate 11 is provided on the top 5a of the ski 5 in the region of the ski binding, said damping plate 11 essentially extending over the longitudinal direction extends over the entire binding region and is rigidly connected to the ski 5 either in the region of the toe 1 or the heel 2.
  • the damping plate 11 has a central bore 14 in the shoe support area of the toe 1 for fastening it to the ski 5.
  • the bore 14 also leads through the connecting lug 6d of the front fastening block 8, so that this fastening block 8 can also be fastened to the ski 5 together with the damping plate 11.
  • the damping plate 11 has recesses 12a, 12b, 12c, 12d or 13a, 13b, 13c, 13d in the form of openings through which the holding bodies 6a, 6b, 6c , 6d, 7a, 7b, 7c, 7c protrude beyond the top 11a of the damping plate 11.
  • the dimensions of the recesses 12a, 12b, 12c, 12d, 13a, 13b, 13c, 13d are selected so that their width essentially corresponds exactly to the width of the associated holding bodies 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7c However, their length is greater than that of the corresponding holding body 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7c in order to produce a mutual play in the longitudinal direction between the damping plate 11 and the holding bodies.
  • the damping plate 11 has, at least in its front and rear end regions, a damping layer 15 or 16 which is firmly connected to the underside 11b of the damping plate 11, e.g. is glued.
  • the damping layer 15, 16 is only provided in the area in front of the toe 1 or behind the heel 2 and is firmly connected to the upper side 5a of the ski 5, e.g. glued to this.
  • the damping plate 11 is designed as a U-shaped profile, the two lateral legs 11c, 11d of which are aligned in the direction of the upper side 5a of the ski and form a lateral edge of the damping plate 11.
  • the damping plate 11 also has a border in the form of legs 11e, 11f, which are aligned in the direction of the upper side 5a of the ski.
  • This boundary 11c, 11d, 11e, 11f forms a cavity between the damping plate 11 and the upper side 5a of the ski, which serves to receive the damping layer 15, 16 and the fastening blocks 8, 9.
  • the height of the holding body 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7c of the mounting blocks 8, 9 is greater than the height of the legs 11c, 11d, 11e, 11f of the damping plate 11, so that a distance above the damping plate 11 Support surface for the front or heel jaws is formed, whereby there is no friction with a relative movement of the damping plate and the front jaw 1 or the heel jaw 2.
  • the damping plate 11 also forms the required length-stable connecting element between the front 1 and the heel jaw 2.
  • the rigid connection of the damping plate 11 to the front jaw 1 takes place, as already explained above, via the fastening block 8 or the bore 14.
  • a latch 17 is provided in the damping plate 11 in the area of the heel shoe 2, which ensures a length-adjustable connection.
  • the latching 17 has a latching part 17a rigidly connected to the damping plate 11, which is mounted in a longitudinally displaceable manner in a recess 18 of the guide plate 10, this latching part 17a being provided with a plurality of latching elements 19a, 19b arranged one behind the other, into which a (not shown) Counter-locking element of the heel jaw 2 can snap in different longitudinal positions. If necessary, the latching part 17a can be formed in one piece with the damping plate 11.
  • the latching 17, like the bores in the holding bodies 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7c, serves in a known manner to adapt the ski binding to different shoe sizes.
  • FIG. 3 shows a further development of the ski binding described above, in which a spacer 20 acting between the damping plate 11 and the upper side 5a of the ski is provided in the central section of the damping plate 11. Otherwise, the damping plate 11 is constructed in the same way as that described in FIGS. 1 and 2.
  • the spacer 20 slightly increases the distance between the upper side 5a of the ski and the lower side of the damping plate 11, so that the deflection of the ski is changed in the sense of greater ease of turning in the ready-to-run state.
  • the essentially mushroom-shaped spacer 20 has an annular support shoulder, by means of which it is held in a central bore 21 of the damping plate 11.
  • the spacer 20 is made in one piece from a hard material.
  • the effective height of the spacer e.g. be specifiable by means of an adjusting screw.
  • the damping layer 15 assigned to the front end region of the damping plate 11 and the damping layer 16 assigned to the rear end region of the damping plate 11 extend backwards or forwards to immediately in front of the spacer 20, so that the damping effect of the plate 11 is almost complete takes place over the entire bond area.
  • FIGS. 4a, 4b and 5a, 5b show a second embodiment for a ski binding according to the invention, elements or parts of this ski binding which are the same as those of the first embodiment being provided with the same reference numerals and are no longer described in detail below .
  • the front jaw 1 and the heel jaw are not connected to one another by means of the damping plate 11 but via a length-stable band 22 guided below the damping plate 11.
  • the band 22 is preferably attached to the front jaw 1 in an adjustable length.
  • a plurality of bores 23 arranged one behind the other are provided at the front end of the band 22, by means of which the band can be fastened to the tab 6d of the front fastening block 8 in different longitudinal positions. If the fastening block 8 is fastened to the ski 5 separately from the front jaw 1, the band 22 can be screwed onto the ski 5 by means of the bore 14 together with the tab 6d. If, on the other hand, the fastening block 8 is simultaneously fastened to the ski with the fastening screws of the front jaw 1, the band 22 can be hung on a bolt which projects up or down from the tab 6d.
  • the band 22 is guided in the area of the longitudinal center plane back to the heel jaw, where it is connected to the latching part 17a, which is guided in a longitudinally displaceable manner in a recess 24 in the damping plate 11.
  • the band between the holding bodies 4a, 4b is tapered
  • the connecting tab 7b of the holding bodies 4a, 4b and 4c, 4d is formed in two parts 7b1, 7b2.
  • the locking part 17a of the locking 17 can be supported against a tab or against the top of the ski in order to ensure a secure locking with the heel jaw.
  • the heel jaw is also guided in a longitudinally displaceable manner in a guide rail which is fastened to the holding bodies 7a, 7b, 7c, 7d and has a suitable recess for the latching part 17a.
  • the damping plate 11 can be attached to the ski either in the region of the toe 1 or in the region of the heel 4. Since the damping plate 11 in this case does not serve as a connecting element between the front and heel jaws, it can optionally also be fastened, ie glued, to the ski exclusively via the damping layer 15, 16.
  • damping plate in the context of the present invention can be designed not only in one part, but also in two parts. If necessary, the two parts can also be connected to one another in a length-adjustable manner.
  • a spacer 20 is provided in the central section of the band 22, via which the distance between the band 22 and the ski surface 5a can be predetermined.
  • the mushroom-shaped spacer 20 is in turn held in a bore 21 of the damping plate 11 and has an annular groove on which the band 22 is guided by means of a longitudinal slot 25.
  • the spacer serves to change the bending tension of the ski when the binding is ready for use, so that better turning properties of the ski can be achieved.
  • the damping plate 11 is delivered in a prepared state in which it is already provided with the damping layer 15, 16, with the fastening blocks 8, 9 and optionally with a spacer 20 and / or a connecting band 22.
  • the mounting blocks 8, 9 are initially attached to the top of the ski, the connecting band 22 is optionally attached or screwed in, and the damping layer 15, 16 is subsequently bonded to the top of the ski 5a, or the mounting blocks 8, 9 in leave the damping plate 11 and fasten it by gluing to the ski top 5a.
  • the front and heel cheeks are screwed to the holding bodies 3a, 3b, 3c, 3d, 4a, 4b, 4c, 4d of the fastening blocks 8, 9 by means of screws at the desired longitudinal position
  • the front and the Heel cheeks are screwed into the ski by the holding bodies 3a, 3b, 3c, 3d, 4a, 4b, 4c, 4d of the fastening blocks 8, 9.
  • the latch 17 is finally actuated and locked in the desired longitudinal position.
  • the mode of operation of the damping plate according to the invention comes into play when skiing, in particular when the skier passes through a depression or a tight curve, that is to say when the ski bends more. Due to the length-stable connection of the toe piece with the heel piece, a length compensation takes place on the longitudinally displaceable ski binding part, that is to say in the present case on the heel piece, in a known manner, as a result of which the ski can bend without hindrance.
  • a ski-fixed point is chosen for each binding, which in the present case lies in the area of the toe or in the area of the heel.
  • the length compensation takes place predominantly on the ski binding part which faces away from the ski-fixed fastening point.
  • the dimension of the length compensation is predetermined by the play between the recesses 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7c and the holding bodies 3a, 3b, 3c, 3d, 4a, 4b, 4c, 4d.
  • a further length compensation is possible, for example, by a thrust spring of the heel shoe.
  • an elastic damping layer 15, 16 is provided in the context of the present invention, at least in the front and rear end region of the damping plate, which is firmly connected to the damping plate 11 on the one hand and to the ski top 5a on the other hand.
  • a shear force is exerted on this elastic damping layer, which advantageously leads to a desired damping of the length compensation.
  • the damping is therefore predetermined on the one hand by the elasticity of the damping layer 15, 16 and on the other hand by the distance of the damping layer from the ski-fixed fastening point.
