Definitions

  • the invention relates to a safety ski binding, in particular a heel holder with a sole holder pivotable on a bearing block about a transverse axis, which is held in the downward position by a latching rocker pivotally mounted on the sole holder, which has a latching projection on one side, which in the downward position has a latching bracket Arranged latching nose engages and is provided on the other side with a locking recess into which a locking part loaded by a release spring engages at least in the downward position, which is mounted in a spring housing which can be pivoted relative to the bearing block and can be displaced to a limited extent in guides thereof, the voluntary opening of which Sole holder a release lever pivotally mounted on the sole holder is provided, by its actuation the spring housing can be pivoted up and the locking part can be unlocked from the locking recess of the locking rocker so that the locking rocker is in its (unlocked) position around it e axis (force) can be freely pivoted and the sole holder is acted upon
  • a safety ski binding of the type mentioned at the outset is described, for example, in DE-A-28 38 904 (see FIGS. 1 to 5).
  • the spring is arranged in a cavity of the release lever pivotally mounted on the sole holder.
  • the trigger lever thus forms the spring housing at the same time.
  • this binding is not in the ready-for-entry position.
  • An additional handle is required to reinsert the ski boot or close the sole holder. Either the release lever is first closed by exerting a force so that the locking part snaps back into the locking recess of the locking rocker, whereupon the sole holder can then be closed by pressing it down.
  • the invention is therefore based on the object of designing a safety ski binding of the type mentioned at the outset in such a way that it is in the ready-for-entry position after being opened arbitrarily.
  • a further spring acting on the release lever or the spring housing with the locking part in the closing direction is provided, that this spring is designed as a leg spring which holds the sole holder on the one hand and the release lever or the spring housing with the Locking part, on the other hand, acted on in opposite directions, at least in a phase of arbitrary release, whereby after the sole holder has been opened arbitrarily, the locking rocker is pivoted by the closing locking part, which is acted upon by the leg spring, against the bearing block-fixed counter-locking, until the locking part is again in the locking recess of the locking rocker comes to rest.
  • the release lever forms the spring housing at the same time, it is advantageous if, according to the invention, the (further) leg spring is mounted on the axis carrying the locking rocker and is supported on one side on the sole holder and on the other side on the spring housing or on the release lever. In this embodiment, therefore, no additional components for accommodating and arranging the (further) leg spring are required.
  • leg spring is mounted either on the pivot axis of the sole holder or on the axis carrying the locking rocker arm, one end on which the release lever with the spring housing coupling bolt is supported from above and elsewhere from below on the housing of the sole holder. In both cases, no significant structural changes to the heel holder are required to accommodate and arrange the additional spring.
  • a further development of the invention is that the axis carrying the locking rocker is mounted in two oblong holes running concentrically to the pivot axis of the sole holder on the side walls of the release lever, that the release lever is supported on the pivot axis of the sole holder from above, and that the sole holder for the bolt attached to the release lever each has an exemption in the form of a recess.
  • the axis carrying the locking rocker acts as the pivot axis of the release lever; in the case of a pressure opening, the pivot axis of the sole holder also acts as the pivot axis for the release lever, in which case the relative movement between the axis carrying the locking rocker and the release lever through the two elongated holes in the release lever is made possible.
  • the heel holder is in the ready-to-go position after an arbitrary opening.
  • the pivoting range determined by the two elongated holes in the release lever thereof can be deactivated by means of an arbitrarily actuated lock. This makes it possible, with an effective lock, to close the heel holder with little effort, as has already been mentioned.
  • This lock can now be formed according to the invention by a spring-loaded slide which is displaceably mounted on the release lever in the longitudinal direction thereof and which on one end has a manually actuable actuating attachment and on the other hand has at least a hook-shaped gripping element which, by actuating the slide, comprises the axis of the latching rocker.
  • Another lock that can be easily accommodated can be formed by a spring-loaded slide that is displaceably mounted on the release lever in the longitudinal direction of the release lever, which on one end has an actuation projection that can be grasped by hand, and on the other is fork-shaped and carries two support elements that extend laterally of the locking rocker and by actuating the Slider can be brought under the axis of the locking rocker and support it from below.
  • the invention also has the task of taking measures that the binding is always in a precisely defined position after an arbitrary opening, namely either in the unlocked or in the ready-to-go position, and there is no jamming between the web of the spring housing in its unlocked position with the locking rocker due to improper actuation, in particular due to early release of the release lever.
  • the invention provides that the leg spring is arranged on the pivot axis of the sole holder with forward (in the direction of the sole holder) and, viewed in elevation and in the projection onto the plane of the drawing, crossing legs, wherein, in the driving position and in the first phase of arbitrary opening, the leg pointing down at a stop of the Sole holder from below and the leg pointing upwards is supported on a bearing block-fixed stop from above, so that the leg spring acts as an opening spring, and that the spring housing also has a stop which, in the plane of the leg of the leg spring supported on the bearing block-fixed stop is pivotable and which in this position of the sole holder, viewed in the vertical direction, lies at a distance below the leg of the leg spring, this stop in the second phase of the arbitrary opening, in which the web is in its position unlatched from the locking recess of the locking rocker located, abuts against said leg from the bearing-fixed stop and from this phase of arbitrary opening urges the spring housing into its closed position
  • the heel holder automatically comes into its ready-for-entry position when the sole holder is opened by actuating the release lever when the skier releases the release lever earlier before he would have stepped out of the binding with his ski boot.
  • the ease of use is therefore significantly improved.
  • a preferred embodiment of the invention is that a further leg spring is arranged on the pivot axis of the sole holder, the legs of which are supported on the one hand on the bearing block and on the other hand on the stop of the sole holder and which continuously urges the sole holder into the open position. This ensures that the binding opens reliably even under the most unfavorable weather and slope conditions.
  • Another advantage of the invention is that the force of the first leg spring (the return spring) is significantly less than the force of the further leg spring (the opening spring acting on the sole holder). This ensures that the return spring is always securely supported on the sole holder.
  • Another advantage of the invention is that the force of the (further) leg spring is lower, preferably substantially lower, than the force of the opening spring acting on the sole holder.
  • FIG. 1 show a first exemplary embodiment, with FIG. 1 the safety ski binding in a side view in section in the downhill position, FIGS. 2 and 3 the safety ski binding each in a position during an arbitrary opening likewise in a side view in section and FIG. 4 are the open position of the safety ski binding after arbitrary opening or after a safety release; 5 to 8 a second embodiment of a safety ski binding according to the invention, which in turn essentially correspond to FIGS. 1-4 of the first exemplary embodiment, the FIG.

  • a bearing block 5 is fastened on the base plate 4 and carries a pivot axis 7 on its rear region adjacent to the base plate 4, on which a sole holder 6 is pivotably mounted.
  • the sole holder 6 carries on its upper area on a further axis 8 running parallel to the first-mentioned axis a likewise pivotable latching rocker 9, which extends essentially downward and has a latching projection 9a at its lower end, which according to the heel holder 1 is in the downward position Fig.1 1 engages below an opening formed on the bearing block 5, counter-latching '10th
  • a top view of an approximately U-shaped spring housing 11 is also pivotably mounted, which has longitudinal slots 11 a in its two side cheeks, which form a guide for a locking part 12.
  • the locking part 12 is acted upon by one end of a release spring 13, the other end of which is supported on a spring abutment 14 which is adjustable in the axial direction of the release spring 13 by means of a screw 15 rotatably mounted in the spring housing 11.
  • a locking pan 9b is formed for receiving the locking part 12, into which the latter is pressed in the downward position by the release spring 13.
  • an opening is provided on the locking rocker 9 in the form of a recess 9c, into which the locking part 12 snaps briefly in the manner to be described while actuating a release lever 16.
  • the release lever 16 also overlaps the sole holder 6 and is pivotally mounted on the axis 8 arranged on the sole holder 6, on which axis 8 the locking rocker 9 is also articulated.
  • a bolt 17 fastened to the release lever 16 parallel to the axis 8 passes through both the sole holder 6 and the side walls of the spring housing 11 and is slidably guided in these two components in elongated holes 6b and 11b, respectively.
  • the two elongated holes 6b provided on the sole holder 6 are arranged concentrically to the pivot axis 8; the two elongated holes 11b formed on the spring housing 11 run in a straight line approximately at right angles to the longitudinal extent of the elongated holes 6b of the sole holder 6.
  • the counter-locking 10 cooperating with the locking rocker 9 is formed on a part of the same which is pulled up at the front end region of the bearing block 5.
  • the counter detent 10 viewed from the top of the ski, initially forms a detent surface 10a, which is engaged by the detent projection 9a of the detent rocker 9 in the downward position of the heel holder 1.
  • a stop is formed by at least one offset 10d in cooperation with a shoulder 6c attached to the sole holder 6 to prevent the sole holder 6 from swinging up too far when the binding is opened.
  • the back surface 10b adjoining the locking surface 10a of the counter-locking 10 is designed as an essentially flat surface which is slightly inclined in the direction of the front jaw, not shown.
  • a leg spring 20 is wound around the axis 8 carrying the locking rocker 9, the two free end regions of which point towards the end of the ski, one end of the leg spring 20 being supported on the bolt 17 and the other end on the underside of the upper cover of the sole holder 6 .
  • an opening spring 21 is furthermore mounted on one side of the binding in the area between the spring housing 11 and on the bearing block 5, which is attached at one end to the base plate of the bearing block 5 and at the other to one on the sole holder 6, is supported in the binding interior pointing stop 22.
  • the mode of operation of the heel holder 1 in question is as follows: if a ski shoe (not shown) inserted into the binding exerts a force on the sole holder 6 in the vertical direction, the sole holder 6 pivots upward about its pivot axis 7. During this pivoting movement, the latching rocker 9 slides along the latching surface 10a of the counter-latch 10 fixed on the bearing block and presses the locking part 12 back against the force of the release spring 13 in the longitudinal slots 11a of the spring housing 11. During the pivoting movement of the sole holder 6, the spring housing 11 is also pivoted about the pivot axis 7 in the same way, so that the locking rocker 9 remains under the action of the release spring 13.
  • the sole holder 6 pivots supported by the opening spring 21 arranged on the pivot axis 7 into its open position. In this way, the release spring 13 can relax until the locking part 12 strikes the end regions of the longitudinal slots 11a of the spring housing 11 facing the locking rocker 9.
  • the binding is now in its ready-to-go position, which is shown in FIG. 4. The binding is closed from this position simply by depressing the sole holder 6 into the position shown in FIG. 1.

  • a resilient catch for the slider 28 can be provided on the release lever 216, which latches in a corresponding latching recess during the actuation of the slider 28.
  • An automatic unlatching of the slider 28 is possible, for example, by designing the actuation area of the slider 28 as a separate component which is designed as a two-armed lever articulated on the slider 28, one lever arm of which carries the actuation projection and is directed in the direction by a further spring is applied to the underside of the release lever 216 and the second lever arm of which points away from the underside of the release lever 216.
  • This second lever arm can now strike, for example, the pivot axis 107 during the depression of the trigger lever 216, as a result of which the lever is pivoted and the latching is released automatically.
  • a slide can be provided with two lateral support tabs which can be brought under the axis 8 by actuating the slide and support it from below from below.
  • the support tabs provided at the end region of the slider viewed in the downward position of the heel holder according to FIG. 10, are located on the side of the locking rocker 9 in the area behind the axis 8. It is therefore necessary to move the slide towards the sole holder.
  • gripping elements can also be provided, which are in the unactuated position of the slide in the area behind the axis 8 of the locking rocker 9 and can be pushed laterally on the axis 8 of the locking rocker 9.
  • the exemplary embodiment according to FIGS. 11-14 shows a heel holder 301 with a further modification of the design and arrangement of the leg spring 320.
  • This is wound around the common pivot axis 7 of the sole holder 6 and spring housing 11, the free end regions — both legs of the leg spring 320 point forward, in the direction of the sole holder 6, and the leg spring 320, viewed in the driving position, is supported with one of its legs 320b on a bearing block fixed to the bearing block 305a and with its other leg 320a on a stop shoulder 22 attached to the sole holder 6.
  • the two legs 320a, 320b cross, as shown in particular in FIG. 11, in the projection onto the plane of the drawing.
  • the spring housing 311 also has a stop 311c, which is located in this position of the heel holder 301 in the vicinity of the base plate 4, at a distance from the leg 320b of the leg spring 320 which is supported on the bearing block fixed stop 305a.
  • the stop 311c of the spring housing 311 can be swiveled up in the plane in which the leg 320b of the leg spring 320 which is supported or can be supported on the bearing block fixed to the bearing block lies.
  • the leg spring 320 fulfills, as will be explained on the occasion of the function of the heel holder 301, both the function of an opening spring and that of a return spring.
  • the operation of the heel holder 301 corresponds to an involuntary triggering process, e.g. B. in a fall of the skier, that of the embodiment of FIGS. 1-4.
  • the release lever 16 is pivoted upward, for example by hand, in the direction of the arrow F "shown in FIG. 11.
  • the bolt 17 which is pivoted upward in the elongated holes 6b which are concentric to the axis 8 the Fe
  • the housing 311 is pivoted up about the axis 7, the locking part 12 being moved out of the locking recess 9b of the locking rocker 9 against the force of the spring 13.
  • the recess 9c of the locking rocker 9 adjoining the locking recess 9b in turn allows the release spring 13 to relax (see FIG.
  • the locking rocker 9 now no longer being spring-loaded and when the sole holder 6 is subsequently pivoted upwards under
  • the effect of the leg spring 320 which in turn acts as an opening spring in the first phase of the arbitrary opening of the heel holder 301, can be pivoted to such an extent that it slides upwards along the counter-catch 10.
  • FIG. 13 shows the heel holder 301 in a position with the sole holder 6 not yet fully pivoted up, the latching rocker 9 being in an intermediate position on the counter-latch 10 and the leg 320b of the leg spring 320 having moved somewhat away from the bearing block-fixed stop 305a.
  • the spring housing 311 While the spring housing 311 has reached this predetermined obliquely upward-pointing position, the leg 320b of the leg spring 320 supported in the travel position on the bearing block fixed stop 305a of the leg spring 320 was lifted off the stop 305a by means of the stop 311 c attached to the spring housing 311, so that the leg spring 320 now Sole holder 6 and the spring housing 311 in opposite directions, u. e.g. w.
  • a further leg spring 421 is mounted on the pivot axis 7 of the sole holder 6 of the heel holder 401, which with one of its legs 421 b on the base plate of the bearing block 305 and with its other leg 421 a the attached to the sole holder 6, in the binding interior facing stop 22 is supported.
  • This leg spring 421 acts exclusively as an opening spring.
  • this heel holder 401 corresponds to that of the heel holder 301 described with reference to FIGS. 11 to 14.
  • the mode of operation of the heel holder 401 according to FIGS. 15 and 16 differs from that of the heel holder 301 insofar as the additional leg spring 421 as described Sole holder 6 is acted upon in the opening direction during the entire course of the arbitrary opening and thus for resetting the spring housing 311 and the release lever 16 by means of the (first) leg spring 320 in the second phase of the arbitrary opening by means of the stop attachment 22 fixed to the sole holder for the one leg 320a of the latter Spring (320) forms a defined support.
  • the invention is not restricted to the exemplary embodiments shown. Further modifications are conceivable without leaving the scope of the scope of protection. So it is particularly possible to pivot the bearing block on a vertical axis to be fixed to the base plate in the horizontal plane and at the same time to provide a control curve at the front end region of the base plate, which cooperates with a counter-catch arranged on the sole holder, so that a so-called diagonal release control given is. Since the measures required for this are known per se, the details in this regard were not dealt with in the description. Furthermore, it is conceivable to arrange the leg spring on an additional bolt mounted on the sole holder.
  • leg spring instead of the leg spring, which is also supported on one end on the sole holder and on the other side preferably on the bolt coupling the spring housing to the release lever.
  • the spring could also be supported on the spring housing itself.
  • the arrangement of such a spring is also possible in a binding system in which the release spring is arranged in a cavity of the release lever itself. In this case, it is then possible, for example, to support the spring on part of the release lever in such a way that it acts in the closing direction is struck, whereby the spring housing with its locking part reaches the area of the locking recess of the locking rocker.
  • sole holder The component used to hold the ski boot, which can be swiveled up around the pivot axis fixed to the bearing block, was referred to as such a “sole holder”.
  • this designation not only applies to the actual sole holder (in the narrower sense) used to hold down the heel of the ski shoes, possibly with a conventional step spur used to get in, and the area generally covering the bearing block in the driving position, generally referred to as the housing, on which the sole holder is attached or articulated.
  • building parts designated as sole holder fixed also include an arrangement fixed to the housing.
  • the force of the additional spring is lower, preferably substantially lower, than the force of the opening spring acting on the sole holder.
