Definitions

  • the invention relates to ski bindings, and more particularly to spring loaded, quickly releasable ski bindings in which the heel unit is locked by stepping onto the ski and is released through the actuation of a spring feature a heavy steel construction with precision ma-v chined parts and complex and expensive adjustment mechanisms.
  • These mechanisms also include spring loaded latch elements which are actuated by the boot as the skier steps onto the ski.
  • the latch element is releasable by either the deliberate operation of a release element or under a predetermined stress onthe heel of theski boot, as in safetybindings.
  • a further object is to provide easy adaptability of the ski binding as a safety ski binding for use on both junior skis and full-size skis.
  • the invention proposes to attain the above objects by using a ski binding where a pivotable, spring loaded latch is arranged inside a likewise pivotable housing of the heel unit.
  • a horizontal nose on the vertical latch engages one of two saw-tooth abutments on the housing.
  • a horizontal compression spring urges the latch against the abutments in such a way that theheel unit is locked in place as the housing is pivoted into the horizontal position.
  • Release of the housing is obtained by depressing an offset lever portion of the latch against the spring pressure. It may also be obtained automatically at a predetermined opening pressure generated by the boots when the engaging parts between the latch and the housing have been positioned to operate as a safety release.
  • the lever portion of the latch is preferably accessible from above through an opening in the housing so as to be operable by means of finger pressure or with a ski pole.
  • the solution provided by theinvention features a minimum of structural elements, most of which are preferably of plastic material and injection molded.
  • the heel unit of the invention also features a single compression spring which performs a double function in that it provides the preload for the latch and also I produces the opening movement for the housing when the latch is released. This double action spring is also conveniently adjustable from the outside to obtain different locking and release characteristics.
  • One version of the invention provides alocking action between the latch and the housing which can only be released by a deliberate release movement on the latch lever.
  • the locking elements are positioned to operate as an automatic release mechanism to serve as a safety binding which releases the ski boot-under a predetermined overload.
  • the invention utilizes locking elements in which the abutment faces on the housing and/or the locking nose on the latch are rounded or arranged obliquely so as to provide a cam engagement, Y
  • the locking action of which is a direct function of the spring load applied to the latch. It is also possible to replace one of the two locking faces by a roller which is carried by a horizontal pin; It isfurtherpossible to provide the locking element on the housing as a separate structural part so that the housing is always the same injection molded part, regardless of the type of locking action provided by the locking elements. Such a special interchangeable locking element may be attached to the housing wall by either screws, pins, or bonding. Thus, the modification from one locking characteristic to another locking characteristic merely requires the replacement of interchangeablelocking plates on the housing and locking latches themselves. All other parts remain unchanged.
  • the horizontal compression spring is so arranged that its rear end engages an integral protrusion on the rear wall of the housing and its forward end engages a centering recess on the vertical leg of the latch lever.
  • the protrusion on the rear housing wall be replaced by an adjustable threaded pin which engages a threaded bore in the housing wall and which is long enough to provide any required adjustment.
  • a further preferred feature of the invention provides for a longitudinal adjustment of the heel unit relative to the toe unit of the ski. This is obtained by means of longitudinal lateral protrusions on the base plate of the housing. The housing is then adjustably clamped onto the ski by means of two clamping profiles which engage matching teeth on the housing protrusions. Adjustment is obtained by loosening the screws which retain the clamping profiles, whereby the latter can be lifted to release the toothed housing ledges permitting the heel unit to be adjusted toward or away from the toe unit. Retightening of the clamping screws gives the heel unit a firm longitudinal and vertical hold.
  • a further provision of the invention relates to the initial mounting of the heel unit on the ski which can be simplified by providing the two injection molded clamping profiles with exterior, transverse connecting yokes so that the two profiles form a one-piece molding. In this manner, the two profiles can be conveniently screwed onto the ski in the proper alignment and with the correct lateral distance, whereupon the connecting yokes are broken away from the clamping profiles.
  • FIG. 1 is an elevation view of a toe unit as part of a ski binding embodied by the invention
  • FIG. 2 is a plan view of the toe unit of FIG. 1;
  • FIG. 3 is a plan view of a heel unit as part of a ski binding embodiment by the invention.
  • FIG. 4 is a side view of the heel unit
  • FIG. 5 is an elevational cross sectional view of the heel unit of FIGS. 3 and 4 taken along line AA of 7 FIG. 3;
  • FIG. 6 is a plan view of a pre-assembly molding of the clamping profiles for the heel unit of the invention.
  • FIG. 7 is a cross-sectional view taken along line 8-13 of FIG. 6.
  • a toe unit 1 includes a hollow main body produced of injection molded plastic which has a central cavity 2 for weight saving and a pair of opposite lateral lugs 3 with bores 3' for screws attaching it to the ski.
  • the toe unit further includes a recess 4 on its rear side which is traversed by a vertical threaded adjustment pin 5.
  • the adjustment pin engages in a known manner a wing-shaped boot retaining cup 6 which can be adjusted vertically by rotating the pin and which is secured against rotation by its lateral engagement with the recess 4 inside the body 1.
  • This toe unit is permanently mounted on the ski, adaptability to different boot sizes being provided by adjustments on the heel unit.
  • the heel unit as shown in FIGS. 3-5 includes a main housing 8 which contains in its forward portion the same boot retaining elements as in the toe unit, viz. a wing-shaped cup 9 engaging a lateral recess 10 and a threaded adjustment pin 11 for vertical adjustment to the thickness of the heel rim of the boot.
  • a housing 12 Underneath the cup 9 a housing 12 includes a forwardly extending trip plate 13 which extends under the heel of the boot so that, when the skier steps into the ski binding, the housing is pivoted downwardly from its open position into its horizontal locking position.
  • the housing 12 pivots around a horizontal pivoting pin 14 which is located near the lower rear end of the housing. Pin 14 is mounted on a bottom plate 15 which includes a pair of laterally spaced ears 16 holding pin 14.
  • the bottom plate 15 further includes a second pair of ears 17 located forward of the ears 16 and holding a second pivoting pin 18 on which is pivotably mounted a latch 19.
  • the latter consists of an upwardly extending portion in the form of a generally vertically arranged leg 20 which extends upwardly from pin 18 and an actuating arm 20 which extends rearwardly from the upper end of leg 20 so as to be accessible through an opening 20" in the upper wall of housing 12.
  • the latch leg 20 further includes on its upper end a forwardly extending nose 21 which engages a latch element 22 on the housing 12.
  • the latch element is in the form of a latch plate 22 which is mounted on a forward transverse wall 29 of housing 12.
  • a biasing means in the form of a horizontally extending compression spring 23 urges the latch 19 into engagement with the latch plate 22 of housing 12.
  • spring 23 engages a centering recess 23' in the vertical leg 20 of latch 19, thereby tending to pivot latch 19 in a counterclockwise direction.
  • the rear end of spring 23 engages the rear wall of housing 12 from the inside via a centering pin 24 which may either be an integral part of the molded housing 12 or take the form of a threaded centering pin 25 (FIG. 5) which is adjustably mounted in a threaded bore in the rear wall of the housing.
  • a threaded pin which is much longer than that shown in FIG. 5, especially when it is desired to adapt this ski binding as a safety ski binding.
  • the latch element forms a plate 22 which has two abutment faces 26 and 27 located a distance above one another and linked by a cam shaped cam portion 28 so as to give the latch plate a saw-tooth shaped outline.
  • nose 21 of the latch 19 presses against the upper abutment face 26 of the latch plate, and this locked position is maintained by compression spring 23.
  • the heel unit 8 is only then openable, i.e., pivotable upwardly, when latch 19 is forceably moved against the force of spring 23 by depressing the actuating arm 20 either with a finger or with the end of a ski pole. This causes latch 19 to move clockwise against spring 23, thereby releasing the nose 21 from theabutment face 26.
  • the latch element 22 is also possible to provide the latch element 22 as an integral part of the housing 12.
  • the preferred embodiment provides a separate latch plate 22 (as shown in FIG. 5) which may be attached to the housing by screws, rivets, or by bonding.
  • This has an advantage in that the heel unit can easily and inexpensively be provided with the elements of a safety binding, when the latch plate 22 as shown is replaced by a different latch plate which, instead of having the saw tooth outline has rounded abutment portions or a different angle on its abutment faces, depending on the friction coefficient of the materials used.
  • a modified latch lever 19 the nose 21 of which either includes a roller on a horizontal pin or has an appropriately rounded or slanted outline.
  • the latch With a heel unit modified in the above manner it is possible for the latch to be opened by the ski boot, which when it exerts an upward pressure against cup 9 of the unit, causes the latch plate 22 to be snapped from under the nose (or roller) 21 of latch 19 by moving the latter against spring 23.
  • the amount of force required to affect such a release can be adjusted by adjusting the preload condition on the compression spring 23. This adjustment is obtained on the threaded pin 25 which may include a dial or other visible reading marks on the housing 12 so as to allow a convenient setting of the critical release conditions.
  • the earlier described snaplatch unit (shown in FIG. 5) can thus be quickly and expensively transformed into a safety binding by modifying three simple parts, viz. latch plate 22, latch lever 19, and a longer adjustment pin 25.
  • the base plate of the heel unit is laterally larger than the housing 12 itself.
  • These lateral longitudinal protrusions on base plate 15 are engaged by matching longitudinal clamping profiles on either side of the housing which overlap the protrusions and thus press the base plate 15 against the ski.
  • the mating faces of the base plate protrusions and of the clamping profiles further include matching transverse serrations to possibly prevent any longitudinal displacement of the heel unit relative to the clamping profiles 30.
  • the teeth of the transverse serrations are approximately 1 mm deep.
  • the two clamping profiles 30 are attached to the ski by means of several screws 31 (FIG. 4). Both the base plate 15 and the two clamping profiles 30 with their serrations are injection molded from plastic material.
  • An additional advantageous feature of the invention resides in the fact that the two clamping profiles 30 are injection molded as a single one-piece unit as shown in FIG. 6. This is done by adding to the ends of the two profiles connecting yokes 32 which hold the two profiles in proper alignment and in correct lateral spacing. This frame-like molding which can be slipped over the heel unit greatly simplifies the initial mounting of the unit on the ski by preventing any misalignment during the drilling of the holes for the screws 31. Once mounted, the connecting yokes 32 are simply broken off. This is simplified by providing weakening notches 32' between the ends of the clamping profiles 30 and arms 33 of the connecting yokes 32.
  • a ski binding heel unit comprising:
  • a base plate adapted to be secured to the ski
  • said housing being pivotally movable on said rear ear means for movement between an open, step-in position and a closed, retaining position
  • said housing having a latch member thereon, said latch member including a pair of abutment faces thereon,
  • a release lever pivotally connected to said front ear means and including a rearwardly extending lever arm and a forwardly extending nose, said nose being engagable with said abutment faces, and
  • spring means positioned between said housing and said release lever for biasing said release lever into contact with said abutment faces and biasing said housing toward its open position.
  • a ski binding heel unit as defined in claim 1 8.
