Definitions

  • the present invention relates to ski bindings. More in particular the invention concerns a heel retainer for a ski binding which has a lower part or support retained on the ski or by its base plate and a top part that may optionally be latched with the support for starting and unlatched for competition events, which carries the sole retainer and is connected with the support, while it can be raised by a predetermined amount from the lower part or support for competition runs.
  • the retainer In the position for starts the retainer must press the heel firmly against the base plate of the ski, while in the position for competition runs the ski must, of course, be held, but raising and lowering of the binding by a certain amount from the base plate must be permitted.
  • heel retainers of this type optional adjustment for competition runs or for starts is made possible by means of parallelogram gears or bars or additional guide bars.
  • Such forms of construction are relatively expensive and require considerable space. Due to the relatively large number of joints required for this purpose there results an undesirable amount of tolerance and, therefore, inaccurate lateral guidance of the sole retainer.
  • the housing of the heel retainer is partly open and consequently it can be plugged up by snow.
  • the latching of the top part with the lower part or support in the setting for starts as well as the releasing of these parts for competition runs is effected by means of rollers and levers. It is relatively complicated and, therefore, correspondingly expensive, as well as subject to failure or jamming.
  • the inner housing and the release mechanism permit the further use of those parts and tools which are already available from a heel retainer for starts of known construction.
  • this may be the heel retainer in accordance with Pat. No. 3,378,371. Then it is only necessary to provide bores for mounting the controlled guide means and the latching device and to connect these components with the outer housing and on it the sole retainer.
  • the skier during competition runs need only move the weight of the outer housing upwardly while the relatively heavy release mechanism is located in the inner housing and consequently on the ski.
  • the release mechanism is disposed in the top part and must therefore continually be raised up during competition runs.
  • FIG. 1 is a side view of the inner housing with the means for the controlled guidance, and with the outer housing shown in dashes in the position for competition runs as well as in the position for starts shown in dot and dash lines only in part,
  • FIG. 2 is a section along the line 11-11 in FIG. 1 where the outer housing is in position for starts,
  • FIG. 3 shows an exploded view of the inner housing 1 and of the release components contained therein
  • FIG. 4 is a longitudinal section through the inner housing with the essential components of a manual release means and the outer housing indicated in dot and dash lines in the position for starts.
  • the heel retainer for holding down the ski includes, first of all, an inner housing. In it are located the release means which can be constructed as desired.
  • the inner housing is pivotally connected to a base that is in fixed position in relation to the ski, for example on the base plate, so that when released with respect to the base or support portion it can execute a rocking or pivotal movement upwardly or downwardly.
  • the inner housing can be guided in the area of its rearward end remote from the side of the boot for sliding movement on the support longitudinally of the ski against a spring bias (see FIGS. 3 and 4).
  • a spring bias see FIGS. 3 and 4
  • the outer housing 2 surrounds the inner housing and carries the sole retainer 3 as well as the stepping plate 4.
  • the outer housing is illustrated in FIG. 1 only in dashed lines in the position of competition runs and in the position for starts only partly in dash and dot lines.
  • the sole retainer is preferably adjustable for height and is rigidly mounted on the outer housing.
  • the latching device 5 see FIGS. 3 and 4) the inner and outer housing may be optionally interlocked.
  • a controlled guide means is provided in the manner of controlled drive elements, which in this embodiment comprises four toothed segments 69 in lever form which are linked in pairs to the outer surfaces of the two side walls of the inner housing 1 by means of rivets 10.
  • the connection of the controlled guide means with the outer housing is preferably by way of slot or slide links, which here are in the form of slots 11 in the ends of the levers, engaged by rivets or pins 12 secured to the outer housing.
  • the outer housing and the sole retainer are held in the position indicated in dot and dash lines (see also FIG. 4) and thus force the heel of the ski boot firmly against the support or base plate. This is the position for start runs. If the latching means 5 is released, however, the outer housing 2 can be lifted up from the inner housing 1 into the position for competition runs shown in interrupted lines in FIG. 1.
  • a release for excessive loads is insured in the position for starts as also for competition runs, because the means for the controlled guidance effectively transmit in both cases the forces from the boot to the inner housing. This applies for the upwardly directed forces (forward fall) as well as also for the laterally directed forces (torsion fall).
  • the heel retainer in accordance with the invention can be elastically supported in the position for start runs with respect to the base or support plate longitudinally with respect to the ski.
  • FIG. 1 illustrates that the distance a of the left joint axle 10 from the center line of the teeth is greater than 4 the corresponding distance b of the right joint axle 10.
  • the outer housing is in its raised position displaced upwardly more at its rearward end than at its forward end that carries components 3, 4.
  • a line drawn in this position through the pins 12 therefore forms the angle or shown in FIG. 1 with that line which passes through these components in the latched position.
  • the angle 0 corresponds to the angular position of the boot during competition runs. Since during its movement in competition runs the heel moves along an are centered at the point of the boot, the forced engagement of the binding always remains under the force at which the binding is set.
  • a particularly firm and stable guidance of the outer housing is obtained in that the inner housing forms at the same time the abutment limits and/or the slide guidance for the outer housing or for its components that move along as the latching device is unlatched.
  • the pins 12 are surrounded by sliding rollers 13 for this purpose which slide along the forward and rearward end surfaces 14, 15 of the inner housing or engage the same to roll on them.
  • the end surfaces 14, 15 may be inclined for adaptation to the arcuate rocking movement of the outer housing explained above; preferably they may extend along an are.
  • the curvature or shaping of the front end wall 14 of the inner housing may be different from that of the rearward end wall 15.
  • damping means may be provided(not illustrated) which on reaching the true end position of the outer housing absorb the kinetic energy of these parts.
  • These may be elastic springs or rubber blocks. Also the use of rubber rollers or buffer between the outer housing and the ends of the toothed segment lever would be possible.
  • FIGS. 3 and 4 An embodiment of the displacement and release means is illustrated in FIGS. 3 and 4.
  • FIG. 3 illustrates perspectively and in an exploded view only those parts which in the event of a release and/or a rearwardly directed pressure load, permit upward rocking and simultaneously rearward displacement of the inner housing.
  • FIG. 4 shows essentially merely those parts which serve for release of the binding by hand or with the aidof the point of the ski.
  • the components in accordance with FIG. 3 as well as also in accordance with FIG. 4 are provided in the heel retainer.
  • the outer housing 2 is also indicated in FIG. 4 in dot and dash lines.
  • the base plate 16 is provided with lateral checks or jaws 17, at the rearward guide slots 18 of which the inner housing is slidingly guided by means of a pin 20 which passes through the bores 21 in the side walls of the inner housing.
  • Two rocking straps 22 are pivotally movable in bores 24 in the jaws 17 by means of bolts 23.
  • a pivot connection provided by means of pin 27 between bores 25 of the forward rocking ends and the bores 26 of the inner housing.
  • a pawl or claw 30 is pivotally mounted by means of the pin 29 behind which in the operating or driving position the pin 27 enters.
  • a spiral pressure spring 32 is disposed at the rearward bearing surface 31 of the claw 30 which is supported at its other end at an adjustable threaded counter bearing 33 of the inner housing.
  • a lever 34 is connected which at its other end is pivotally connected with an angular release lever 35.
  • the release lever 35 is pivotally movable about a pin 20 and projects rearwardly outwardly through registering guide slots of the inner and outer housing.
  • the latching between outer and inner housing can be obtained in any manner desired, for example it may be in the form of a snap latch.
  • the embodiment illustrates a turning latch or bolt which is rotatably supported in the inner housing 2 and has a manipulating device accessible from the outside, for example a rotating knob 36 (FIG. 1).
  • a latch pin 37 serves as the lock which in the latched position (position for competition runs) engages the wall of the inner housing 1 from the bottom. If the turning latch 5 is moved by 90 out of this position, then the latch pin 37 can unimpededly pass upwardly through apertures 38 in the upper wall of the inner housing (see FIG. 3) into the unlatched position for starts. On the other hand, the position for competition runs can be rapidly changed to the position for starts.
  • the outer housing 2 need merely be moved downwardly, and then the knob 36 is turned so that the pins 37 can pass through the apertures 38. Thereupon the latched position is established by turning the knob 36 through an angle of 90.
  • suitable devices for example a friction latch between the latching device and the housing, or a pawl or a resilient ring, etc., one can also obtain that the latch is held in self-locking condition in the position chosen and cannot be inadvertently turned.
  • Heel retainer for a ski binding of the type having a lower part including fixed means firmly supported on the ski and an inner housing movable relative to said fixed means, and a top part adapted to be locked to said inner housing for starts and to be unlocked for touring events, said top part being an outer housing having a sole holder projecting therefrom and being movable upwardly relative to said inner housing during touring events, said inner housing enclosing automatically releasable latch elements such as springs and levers operative to effect the unlatching, and said outer housing being disposed about said inner housing and including a locking device for interengagement and interlocking with-said inner housing, and controlled guide means disposed between and operatively connected to said inner housing and said outer housing operative upon unlocking of said locking device to permit upward movement of the ski boot during touring, whereby said inner and outer housing are movable as a unit relativeto said fixed means.
  • controlled guide means comprise toothed segments each pivotally mounted on at least one side of said inner housing and each having a lever pivotally connected to said outer housing.
  • each said segment defines a unit with its associated lever and said pivotal connections of said levers with said outer housing are in the form of sliding joints.
  • Heel retainer in accordance with claim 4 including slide rollers carried by said outer housing at opposite ends thereof and engaging the end walls of said inner housing for movement thereon.
  • Heel retainer in accordance with claim 5 including pins or the like supported by said outer housing proximate opposite ends thereof and extending through said slide rollers, and where said levers present slots at the ends thereof through which said pins extend.
  • Heel retainer in accordance with claim 9, where a stepping plate extends forwardly of said outer housing for engagement by the heel of the ski boot.
