Definitions

  • a heel hold-down device of the type mentioned at the outset is described in AT-B 294.645.
  • this known embodiment which relates to both a toe and a heel holder, it is disadvantageous that a transverse movement of the binding not only triggers the transverse locking device but also the lifting locking device at the same time.
  • This is disadvantageous in the case of the use of this known heel holder, because a heel holder should be insensitive to purely lateral forces for the purpose of safe ski guidance.
  • both latches for the height and side release forces are formed by a common latching element and by a latch carrier which interacts with it and is effective both for the height and for the sideways release.
  • the catch carrier for the height and sideways release has control surfaces which are effective as one catch each.
  • both the latching element and the latch support are responsible for two triggering devices. From this it follows that - particularly because of structural conditions - compromises have to be accepted.
  • DE-A-28 38 904 also describes a solution that essentially resulted from the addition of the two last-mentioned AT patents and also includes their disadvantages.
  • the known designs also have the disadvantage that with increasing triggers, the mounting in the horizontal plane becomes increasingly sensitive to wobbling, which can make the ski guide inexact if there is no triggering.
  • the invention has set itself the task to remedy this situation and to design a heel holder for a safety ski binding of the type mentioned in such a way that the lever is to be supported in each of its positions on the counter detent provided on the ski-fixed component.
  • the locking element provided on the lever, supported by at least one elastic element is resiliently supported on the counter-locking of the component that can be fixed on the ski, or the counter-locking of the component that can be fixed on the ski is relative to a ski-fixed mounting of this component is resiliently supported on the latching element of the lever in the closing direction of this latching, both the latching element and the counter latching being provided in each case for the side release.
  • the measure according to the invention ensures that the lever is elastically supported in each of its positions on the component that can be fixed on the ski, so that on the one hand the forces acting on the lever can be continuously and non-positively borne by the component that can be fixed on the ski, and on the other hand the triggering process by the choice of one another corresponding surface of the component fixable on the ski and the lever can be determined. Furthermore, it is ensured in this way that minor impacts which occur during skiing do not initiate a triggering operation, because the impacts mentioned are absorbed by the trigger spring compared to the weaker spring force of the elastic element. This means an expansion of the elastic range of the safety ski binding according to the invention, the other determining features, such as dimensions, spring constant, etc., being able to be retained unchanged. Finally, there is a construction that is largely protected from environmental influences.
  • An advantageous embodiment of the invention is characterized in that the component which can be fixed on the ski is arranged in front of the pivot for the supporting body of the heel holder, on the area facing away from the supporting body the counter-detent formed by a control surface of a rocker, roller or sleeve is provided for the side release is, and that the rocker, roller or sleeve is resiliently supported with the interposition of at least one spring on the component fixable on the ski.
  • the component which can be fixed on the ski has a retaining bolt, which retaining bolt is attached to at least one abutment formed from a bent part of the base plate, to bearing points or to a separate binding-resistant abutment and the like Rocker, roller or sleeve carries that a control curve forming the locking element is provided on the lever, which control curve, as known per se, extends essentially transversely to the longitudinal axis of the ski and a locking pan for laterally locked reception of the associated counter-locking (retaining bolt or rocker, Roll or sleeve) for the descent and is then fitted to the locking pan in both directions to the two side edges of the ski with curve sections for a controlled turning camber.
  • a control curve forming the locking element is provided on the lever, which control curve, as known per se, extends essentially transversely to the longitudinal axis of the ski and a locking pan for laterally locked reception of the associated counter-locking (retaining bolt or rocker, Roll or sleeve) for the descent
  • This measure according to the invention ensures a surface-like support between the latching element and the counter-latching in a particularly cheap and simple manner, furthermore a locked position of the heel holder against purely lateral release forces and, after this blocking zone has been removed, a controlled diagonal release is achieved.
  • the retaining bolt lies in a plane running parallel to the top of the ski, extends essentially normal to the longitudinal axis of the ski, that a rocker is mounted on this retaining bolt, one end region of which carries the control surface which acts as a counter-detent, and that The rocker is supported on the component that can be fastened to the ski by means of a leg spring.
  • This solution enables production in a modular series for ski bindings which have to meet different conditions, e.g. B. regarding the age, weight, driving ability, since only the rocker and the spring must be designed differently according to the respective requirements.
  • the top of the component that can be fastened to the ski is designed as a stop for the rocker designed as a two-armed lever, which limits its pivoting capacity. This measure ensures a re-engagement between lever and rocker after each pivoting movement of the lever, i. H. even if the lever would pivot away from the pivoting range of the rocker with its area comprising the control cam forming the locking element.
  • the retaining bolt forms an angle with the upper side of the ski and that a counter-catch designed as a truncated cone-shaped roller is arranged on the retaining bolt, which is acted upon by a helical spring acting in the longitudinal direction of the bolt.
  • a helical spring acting in the longitudinal direction of the bolt.
  • the spring is supported at one end directly at the base of the frustoconical roller and at the other end, preferably with the interposition of a washer, on the abutment. This arrangement enables a particularly compact design for the component that can be fixed on the ski.
  • a still further variant of the above-mentioned inventive concept consists in that the bolt stands up on the base plate, is arranged essentially perpendicular to it and is fastened in the base plate, for example riveted, that a sleeve which can be slid on and off the bolt is provided as a counter-catch, which sleeve carries a flange at its free end region remote from the base plate or is spread out in a flange-like manner, the lower portion of this flange being seated on the control curve of the lever forming the latching element and in that the sleeve is acted upon by a spring which is located between the top of the sleeve and the bottom of the head of the bolt is arranged.
  • a recess is formed in the top of the sleeve, which forms a seat for the spring, the other end of the spring being supported on the head part of the retaining bolt with the interposition of a washer.
  • the lever consists of two holding parts pivotably mounted on the common holding axis, the first holding part carrying the latching element (nose) cooperating with the counter-latch provided on the sole holder and acted upon by the release spring, and the second lever part
  • a two-armed lever is designed as a rocker, that the latching element is provided as a slide on one end region of the rocker-like lever part or is designed as a slide on this lever part, which lever part on its other end region, with the interposition of a spring, on the supporting body is supported, the forwardly facing region of the support body being overlapped by the component which can be fixed on the ski, and in that the second lever part, with its end region comprising the slide piece - and thus the entire lever - is resiliently supported on the component which can be fixed on the ski.
  • This embodiment is characterized by the independent design of the lever and the locking element associated with it.
  • the first lever part of the lever has a recess running in the longitudinal direction of the ski, the rocker-like (second) lever part being arranged to penetrate this recess on the common holding axis.
  • the second lever part has at its end having the spring a downward extension which serves as a centering for the spring, and that the forwardly extended region of the support body has a recess designed as a seat for receiving the other end of the spring. This provides a secure hold for the spring even without lateral guidance.
  • a still further embodiment of the invention is characterized in that the second lever part, in relation to the holding axis of the two-part lever, about which it can be pivoted, is designed as a one-armed lever with an extension, the second lever part having a recess which is open towards the front has, with its (bearing) region facing the holding axis, engages around the first lever part and the free end region of this second lever part carries the control cam, which acts as a locking element and which engages from below into a counter-catch formed on the component which can be fixed on the ski and bears against it, and wherein the extension is designed as a resilient element (as a resilient support) which is supported on the supporting body and is preferably made of the material of the second lever part.
  • this solution is characterized in particular by its simple and cost-saving method of manufacture.
  • the resilient element is designed as a curved (curved) structure which points from top to bottom and from the back to the front, the cross section of which is preferably constant. This creates a kind of closed construction of rocker and its extension. Furthermore, the designer has more freedom in terms of Choice of dimensions available as if the extension forming the resilient element pointing backwards were open.
  • FIG. 1 and 2 show a first exemplary embodiment of the safety ski binding according to the invention, FIG. 1 being a longitudinal section along line II in FIG. 2 and FIG. 2 being a section along line 11-11 in FIG. 1, 3 to 6 four further exemplary embodiments, each similar to the illustration in FIG. 1.
  • a safety ski binding referred to in its entirety as a heel holder 1 can be seen.
  • 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 can be secured (detachably fixed) in a manner known per se in the desired positions.
  • the manner of the longitudinal adjustment is not the subject of the present invention.
  • a vertical axis designed as a pivot 5 is riveted, around 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 return spring 5a ensures that the heel holder 1 is automatically returned to its central position (in the downward position) after pivoting has been triggered at least partially in the horizontal plane.
  • the supporting body 6 has on its upper region a pivot axis 7, which extends transversely to the longitudinal axis of the ski and parallel to the top of the ski 2, for example and as is known per se, formed by two axle journals 7a, 7b (cf. FIG. 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 invention.
  • the setting of the effective force of the release spring 13 takes place in a known manner by means of an adjusting screw 15 supported on a spring cage 21.
  • the release spring 13 is with one of its end regions on a spring abutment 14 which can be actuated by the adjusting screw 15 and with its other end region with the interposition of a slide 11 , which is guided in the spring cage 21, supported on the lever 10.
  • the lever 10 is designed as a latching support both for one of the latching elements, which yield against the height release forces, and for one of the latching elements, which are effective against the side release forces.
  • a nose 10a of the lever 10 which is supported on an opposing catch 8a of the sole holder 8 from behind, serves as a catch against the swiveling up.
  • the locking effective against pivoting in the horizontal plane is formed by a control cam 12 of the lever 10 to be described in more detail, which is supported on a control surface 17, also to be described, of a component 16 which can be fixed on the ski.
  • the component 16 which can be fixed on skis is formed in the present case by a retaining bolt 18 mounted in an abutment 4a, the details of which will be discussed later, and by a rocker 19 pivotably arranged on the latter.
  • the retaining bolt 18 runs in a plane parallel to the base plate 4 transversely to the longitudinal direction of the ski, so that the rocker 19 can be pivoted in the plane lying vertically to the upper side 2a of the ski.
  • the retaining pin 18 is secured against displacement in the direction of its longitudinal axis relative to the abutment 4a, in a known manner, for example by means of two split pins.
  • the control surface 17 is formed on the (front) end region of the rocker 19 facing the lever 10.
  • the latter is supported on the abutment 4a with the interposition of a spring 24 designed as a leg spring.
  • the abutment 4a consists of two bearing brackets 4a ′′ 4a z , which are fastened, for example welded, to the upper side of the base plate 4.
  • the abutment 4a that is created penetrates a recess 6a of the support body 6. Since the support body 6 is in its assembled position is held by a bent-back guide edge 4b of the base plate 4, the recess 6a of the support body 6 is of sufficient size to be able to mount the support body 6.
  • the support body 6 with its recess 6a is first placed over the abutment 4a, then the front edge 6b of the support body 6 is guided under the guide edge 4b 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 is 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. 2. It can be seen that in the downward position of the heel holder 1, the rocker 19 lies in a locking pan 12a of the control cam 12, which ensures a wobble-free holder in the downward position of the heel holder 1. Following the locking pan 12a, curve sections 12b i , 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 control in the event of a sudden fall. This procedure will be discussed in more detail later.
  • the above-described configuration of the component 16 and the control cam 12 ensures that the lever 10 is supported on the component 16 in each of its positions, so that when the lever 10 is pivoted in the horizontal plane (due to the occurrence of forces both in the vertical as well as in the horizontal plane) the sole holder 8 is held until it is released by the spring-loaded lever 10, so that wobbling of the sole holder 8 or the heel holder 1 neither in the downward position nor during an initiated triggering process until the limit is reached the elasticity occurs.
  • 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 boot, not shown, is pressed by the heel holder 1 in a known manner against a toe, the heel of this ski boot being held between the spur 8b and the holding-down device 8c of the sole holder in a conventional manner. If forces act on the shoe lying in the vertical plane, the heel of the shoe presses against the hold-down device 8c, as indicated by the arrow Pf 1 , 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 in the direction 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 should be familiar to the person skilled in the art without further explanation. If the force Pf 1 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 upper side of ski 2 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 enable triggering both on tension and on 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.
  • FIGS. 6 to 6 those components which are identical to those already described have been given the same reference numerals; Components that are identical in their function, but different in their design, have been identified with one or more dashes (', ","' etc.).
