Definitions

  • the invention relates to a heel hold-down device for a sole holder which can be swiveled about a transverse axis and a vertical axis and which is held in its normal position holding the shoe by and only yielding after overcoming predetermined height or lateral release forces, each consisting of a detent element and a counter detent the effective release force resulting from the simultaneous occurrence of height and side release forces decreases with increasing change in the direction of loading from the vertical to a predetermined limit, the two latching elements being provided separately on a pivotable lever, and which are effective against the height release force Locking element with a counter-locking provided on the rear area of the sole holder forms the first locking, and the locking element effective against the side release forces with a further counter-locking provided on a component fixable with the ski forms the second locking detent forms and wherein the lever is mounted on a holding axis running parallel to the transverse axis of the sole holder, which in turn is arranged in a support body which is pivotable about a pivot pin
  • AT-A-294 645 describes a safety binding of the type mentioned at the outset, which can be used both as a toe piece and as a heel hold-down device. It is disadvantageous here that a transverse movement of the binding not only triggers the transverse latching device, but also the lifting latching device at the same time. This is disadvantageous in the case of using this known ski binding as a heel hold-down device, because a heel hold-down device should be insensitive to purely lateral forces in order to ensure reliable ski guidance.
  • both latching devices for the height and side release forces are formed by a common latching member and by a latch carrier which interacts with it and is effective both for the height and for the sideways release.
  • the ratchet carrier has decisive control surfaces for the height and sideways release.
  • a disadvantage of this known embodiment is that both the latching element and the latch carrier are responsible for two triggering devices. From this it follows that compromises have to be accepted - especially due to structural conditions. Practical experience shows that such compromises have not been satisfactory for the actual solution and that a control cam has been created for a product for side release that is actually marketed, which is provided between the base plate and the housing of the ski binding.
  • This embodiment in turn has the disadvantage that snow, ice or the like can accumulate between the base plate and the housing, as a result of which the triggering processes can become uncontrollable.
  • DE-A-28 38 904 finally describes a solution which has essentially arisen from the addition of the two last-mentioned solutions and which also has their disadvantages.
  • the known designs also have the disadvantage that with increasing lateral triggering, the holder in the horizontal plane becomes increasingly sensitive to wobbling, which means that the ski guidance, if there is still no triggering, can become inexact.
  • the object of the invention is to remedy this situation and to design a heel hold-down device of the type mentioned at the outset such that the lever is to be securely supported in each of its positions on the counter-latch provided on the ski-fixed component.
  • the object is achieved in that the component which can be fixed on the ski has a retaining bolt which extends in the longitudinal direction of the ski, optionally with a roller, which Holding bolt is attached to at least one abutment formed from a bent-up part of the base plate, at bearing points or to a separate binding-resistant abutment and either the holding bolt itself or the roller forms the counter-latching of the second latching, that a control curve forming the latching element of the second latching is provided on the lever is which control curve, as is known per se, extends essentially transversely to the longitudinal axis of the ski and, in order to prevent release in the case of purely lateral forces, a locking pan for receiving the associated counter-locking of the second locking and then connecting this locking pan to the two side edges of the ski has running curve sections for a diagonal release.
  • the measure according to the invention ensures that the lever is supported in any of its positions on the component which can be fixed on the ski essentially without play, so that on the one hand the forces acting on the lever can be non-positively borne by the component which can be fixed on the ski and on the other hand the triggering process by Choice of the corresponding surfaces of the component fixable on the ski and the lever can be determined.
  • This gives the designer a greater choice in determining the triggering process than was the case with known designs.
  • the sole hold-down is centered in the entire elastic range and held in the middle position for getting in.
  • a particularly advantageous embodiment of the invention consists in that the longitudinal axis of the retaining bolt is inclined towards the top of the ski at an acute angle ( ⁇ ), this angle ( ⁇ ) being open towards the tip of the ski, and that the roller provided on the retaining bolt is either as is known per se, cylindrical or frustoconical, the outer surface of the roller as a control surface for the control cam in any position of the lever forms at least a linear, preferably a flat, support.
  • control curve of the lever has an inclination, the angle of which is equal to the angle of the cone from which the frustoconical roller is formed, and that this roller in the direction towards the lever by a spring, e.g. is acted upon by a helical spring surrounding the retaining bolt.
  • This measure ensures a surface-like support between the cam and roller in every position of the lever, which reduces the surface pressure and thus the resulting friction.
  • lever is formed in two parts, the one lever part, which is articulated on the holding axis, resting on the sole holder, the latching element (nose) and the other lever part, which is pivotable relative to the first lever part, the latching element ( Control curve) of the second catch. Due to the split design of the lever, its pivoting capacity is increased, which means that the designer has greater scope for determining the control of the triggering process. Furthermore, the angle of the lever can be chosen more optimally than with a one-piece lever.
  • the first lever part has a recess in which the second lever part is pivotally mounted about the pivot axis of the first lever part, the second lever part being resiliently supported relative to the first lever part by means of a spring, preferably an adjustable helical compression spring.
  • a spring preferably an adjustable helical compression spring.
  • This measure allows undesirable high frictional forces, which should arise between the roller and the cam, to be absorbed by the additional spring. Even bumps on the ground, which transmit brief impacts from the ski to the ski binding, can be absorbed in this way without initiating an undesired triggering process.
  • the adjustability of the strength of a spring by means of an adjusting screw is well known per se. It is used to adjust the spring strength to the respective requirements, which are required, for example, by the skill of the skier or by the ground conditions.
  • a modification of the split design of the lever consists in the fact that the second lever part with its control curve is seated comprehensively on the retaining bolt or on the roller from above, and that this control curve, viewed in elevation, runs obliquely towards the retaining bolt is configured so that the second lever part can be pivoted together with the first lever part in the vertical plane, the control cam rolling along the retaining bolt.
  • the pivoting capacity of the common lever is increased, with the construction of the first lever part being considerably simplified compared to the previous designs.
  • the two-part design of the lever is well balanced by the larger choice in terms of determining the triggering process.
  • the heel holder 1 is held against lifting off from the top of the ski 2 in a known manner by means of a base plate 4 along a guide rail 3, which in turn is fastened on the top of a ski 2 in a known manner, for example by screws, not shown.
  • the heel holder 1 can be displaced relative to the guide rail 3 in the direction of the longitudinal axis of the ski 2 by means of the base plate 4 and secured in a manner known per se in the desired positions, i.e. be releasably fixed.
  • the manner of the length adjustment and the releasable fixation form no object of the present invention.
  • a vertical axis designed as a pivot pin 5 is riveted, about which a support body 6 of the heel holder 1 is pivotably mounted in the horizontal plane, preferably against the force of a return spring 5a.
  • the use of the Rburgholfeder 5a ensures that the heel retainer 1 in its central position after an at least partial pivoting release in the horizontal plane, i.e. in the downhill position, is automatically reset.
  • the support body 6 has on its upper region a swivel axis 7, which extends transversely to the longitudinal axis of the ski and parallel to the upper side of the ski 2, for example and as is known per se formed by two axle journals 7a, 7b (see FIGS. 2 and 2), around which a sole holder 8 is pivotally mounted, as well as a further holding axis 9, which runs parallel to the pivot axis 7 and is arranged approximately in the central region of the supporting body 6, about which a lever 10 is pivotably mounted.
  • a release lever 23 is also mounted on the axle journals 7a, 7b (see only FIG. 1), in which a release spring 13 acting on the lever 10 is accommodated.
  • the arrangement of such a spring in a release lever is known per se and is therefore not an object of the present invention.
  • the setting of the effective force of the trigger spring 13 takes place in a known manner by means of an adjusting screw 15.
  • the trigger spring 13 is with one of its end regions on the inner wall of the adjusting screw 15 acting as a spring abutment 14 and with its other end region with the interposition of a slide 11 which is in one Spring cage 21 is guided, supported on the lever 10.
  • the lever 10 is, as is known per se, designed as a latching support for two latching elements, which cooperate with a counter latching to form two latches, one of which is effective against the height release forces and the other against the side release forces.
  • a nose 10a of the lever 10 serves as a latching element against the pivoting upward, which is supported in an engaging manner from behind on a counter latching 8a of the sole holder 8 (see in particular FIG. 3).
  • the locking element effective against pivoting in the horizontal plane is formed by a control cam 12 of the lever 10, which is to be described in more detail and which is supported on a control surface 17 of a component 16 which can be fixed on the ski and is also to be described and acts as counter-locking.
  • the component 16 which can be fixed on the ski is formed in the present case by a retaining bolt 18 riveted in an abutment 4a and by a roller 19 which is rotatably arranged on the latter and secured in the longitudinal direction of the retaining bolt 18, optionally with the interposition of a washer 20.
  • the control surface 17 is formed on the outer surface of the roller 19, which is cylindrical in this embodiment.
  • the abutment 4a is punched out of the material of the base plate 4, then bent up.
  • the abutment 4a passes through a recess 6a of the support body 6. Since the support body 6 is held in its assembled position by a bent-back guide edge 4b of the base plate 4, the recess 6a of the support body 6 is of a sufficient size to be able to mount the support body 6 .
  • the recess 6a of the support body 6 is first placed on the abutment 4a, then the front edge 6b of the support body 6 is guided under the leading edge 4a of the base plate 4, the support body 6 is pressed forward and then the position of the support body 6 on the base plate 4 fixed by means of the pivot pin 5.
  • the control cam 12 provided on the lever 10 has a shape known per se. This shape is best seen in Fig. 1 a. It can be seen that in the downward position of the heel holder 1, the roller 19 lies in a locking pan 12a of the control cam 12, which ensures a wobble-free holding in the downward position of the heel holder 1. Following the locking pan 12a, curve sections 12b 1 , 12b 2 can be seen on both sides, which point in the direction of the two side edges of the ski 2 and, in accordance with their shape, bring about the prescribed diagonal control in the event of a sudden fall. This procedure will be discussed in more detail later.
  • FIGS. 1 and 2 As a comparison of FIGS. 1 and 2 with FIGS. 3 and 4 shows, on the occasion of a pivoting of the supporting body 6 around the pivot 5 and simultaneous pivoting up of the sole holder 8, the above-described configuration of the component 16 and the control cam 12 ensures that the lever 10 is supported in each of its positions on the component 16 and also the sole holder 8 is held by the spring-loaded lever 10 until it is released, so that the sole holder 8 or the heel holder 1 does not wobble either in the downward position or during a start Triggering process occurs until the limit of elasticity is reached.
  • an opening spring 22 is provided, which is designed, for example, as a leg spring arranged on the pivot axis 7.
  • the operation of the heel holder 1 is as follows. 1 and 2, a ski shoe, not shown, is pressed by the heel holder 1 in a known manner against a toe, the heel of this ski shoe being held between the spur 8b and the hold-down 8c of the sole holder in the usual way. If forces are now acting on the ski boot in the vertical plane, the heel of the shoe presses against the hold-down device 8c, as indicated by the arrow Pf, whereupon the sole holder 8 presses the lever 10 against the force of the release spring 13 to pivot about the holding axis 9 .
  • the control cam 12 of the lever 10 slides along the control surface 17 of the component 16 towards the top of the ski 2 until the nose 10a of the lever 10 is in engagement with the counter detent 8a of the sole holder 8.
  • This position is not illustrated in the drawing; the support of the nose 10a of the lever 10 on the counter detent 8a of the sole holder 8 can, however, be inferred from the principle according to FIG. 3. If the force Pf loading the ski shoe stops acting until there is engagement between the lever 10 and the sole holder 8 in the manner described above, the release spring 13 presses the lever 10 and thus the sole holder 8 against the heel in the direction of the top of the shoe Skis 2 down and the skier remains in the binding.
  • the release lever 23 is actuated.
  • the release lever 23 can either be depressed or pulled up according to the double arrow Pf f .
  • Devices of this type which make it possible to trigger both lift and pressure, are known per se and do not form the subject of the present invention. It is also known to design the release lever for receiving the end of a ski pole or a lanyard.
  • the structure of the heel holder 1 'with regard to the arrangement of its base plate 4', on the guide rail 3 fastened on the upper side of the ski 2, corresponds to the solution already described.

  • the support body 6 is also acted upon by the return spring 5a.
  • the lever 10 ' is pivotable about the holding axis 9; the control curve 12 'on the lever 10' runs in the direction towards the top of the ski at an angle ( ⁇ ) which is still to be described.
  • the component 16 ' which can be fastened to the ski is fastened in the present case to an abutment 4'a which passes through the recess 6a of the support body 6 at an incline upwards. That end of the abutment 4'a, which carries the component 16 ', therefore deviates from the plane normal to the base plate 4' and to the longitudinal axis of the ski 2 by an angle (a). Thus, the longitudinal axis of the retaining bolt 18 forms an angle ( ⁇ ) with the top of the base plate 4 '. Due to the geometric design, theoretically a is equal to ⁇ ; in practice, however, deviations can arise.
  • the roller 19 ' is also cylindrical in shape here, its control surface 17', which is shown in section by two boundary lines, also enclosing the angle ⁇ with the top of the base plate 4 '.
  • the base plane of the control cam 12 'of the lever 10' also extends at an angle to the top of the base plate 4 '.

  • This configuration of the second latching ensures that in any position of the lever 10 'between the control cam 12' and the control surface 17 'of the component 16', a support is provided which takes place along a surface section. This is favorable in order to avoid a high surface pressure, which generates undesirable frictional forces, such as those that occur with a line support.
