  • the present invention relates to ski bindings. More in particular, the invention concerns a self-releasing heel retainer for a ski binding with means for optional setting or adjusting for cross'country runs or starting events such as slalom events.
  • the retainer is pivotable transversely of the longitudinal direction of the ski about a base portion fixed to the ski, as well as displaceable relative thereto.
  • the invention is primarily based on the problem to accomplish with simple means the optional shifting of the binding from cross-country runs to starting runs while avoiding the shortcomings in a heel retainer of the type aforementioned. At the same time, the maximum possible raising height of the sole retainer in the position for crosscountry runs is to be increased, but while keeping the structural height of the retainer as small as possible.
  • the arrangement in accordance with the invention is substantially simpler and therefore cheaper than the known sole-holders, because the number of the link joint connections required is very small. This imparts to the heel retainer also considerable robustness and prevents the adverse effects of linkage play transversely of the longitudinal extent of the ski. All components of the assembly are satisfactorily shielded against the entrance of snow and ice as a result of the housing members which can be fitted or slid onto one another due to the boxlike construction.
  • FlG. l is a perspective exploded illustration of the individual structural components of the outer and intermediate housings including the associated parts;
  • FlG. 2 is a perspective exploded view of the base portion including the baseplate and its associated parts;
  • FlG. 3 is a sectional view taken centrally of the retainer in the position of the latching means for starting runs or events where only the outer housing and the holding down portions are in section;
  • FIG. 4 is a section similar to FIG. 3, but upon release of the holding spring.
  • FIG. 5 is a schematic side view of the heel-retainer-latching means in the position for cross-country runs, as well as with the outer and the intermediate housing suitably raised.
  • intermediate housing and outer housing are boxshaped and are each formed with lateral cheeks or walls that are disposed vertically and extend longitudinally of the ski.
  • the intermediate housing is slid over the base portion and the outer housing over the intermediate housing.
  • the intermediate housing 2 is connected with the base portion 3, preferably its lateral checks 3, by way of a front and a rear linkage or joint, both of which are disposed transversely of the length of the ski and may be lifted off.
  • a front and a rear linkage or joint both of which are disposed transversely of the length of the ski and may be lifted off.
  • pins or bolts 6, 7 are suitable, which in accordance with the embodiment are provided in the intennediate housing, which fit into forward slots 9 that extend generally perpendicularly upwardly and rearward slots E of the base portion that extend generally horizontally rearwardly and are slightly inclined.
  • connection parts 6, 8 define the rearward linkage means and parts 7, 9 the forward linkage means.
  • a slide member 10 serving as a latching means that is guided between the sidewalls 3' for sliding longitudinally in the direction of the ski.
  • transverse pins M are secured in the sidewalls, which enter corresponding slots 112 of the slide.
  • the slide is provided at its top with a projection 13 which engages a corresponding recess or dip M of a tilting key 15 that is rockably supported at its bore 16 by way of a pin 16 in eyelets 16" of the'upper part ofthe housing about an axis extending horizontally and transversely with respect to the longitudinal extent of the ski.
  • the upper side of the tilting key is provided with two actuating surfaces that are defined by recesses A and T for receiving the point of the ski pole. These actuating surfaces are accessible through an opening 1' in the top side of the outer housing.
  • a different arrangement could serve for actuating the latching means which here is in the form of a slide, for example an eccentric member that is rocked or moved to the desired position by means of a turning knob that is accessible from the outside.
  • the rearward linking bolt is utilized which passes through the bore 17 of the intermediate housing as well as also bore 18 of the outer housing, in such a manner that there it permits the aforementioned scissorlike shifting of these two housing components relative to one another.
  • the aforementioned bores as well as the other bores are provided in both sidewalls of the components I to 3.
  • a guiding pin or the like 20 is slidably guided in a slot 22 of the base portion or its side checks 3' that preferably extends arcuately from the bottom to the top and passes at the same time through the slots 23 of the intermediate housing that extend generally perpendicularly to the slots 22.
  • the pin 20 has rivet heads (not illustrated) that slidably engage the outer flanks of the intermediate housing for guidance.
  • a displaceable joumaling is provided for the intermediate and outer housing relative to the base portion which permits the upward rocking of the outer housing out of the position in FIG. 3 into the position shown in FIG. 4.
  • a particularly advantageous manner of operation is provided when the slot 8 for the rearward linkage 6 is directed rearwardly as described, so that outer and intermediate housing can also be displaced in that direction with respect to the base portion.
  • This provides advantageous running and release characteristics in such a binding. Besides, this contributes further to decreasing the structural height as well as for increasing the angle of opening in the position for starting runs (FIGS. 3, 4). It is understood, however, that the principle of the present invention can also be utilized with success in differently constructed bindings.
  • a pressure spring 24 is provided, which at its rearward end is biased in the base against a setscrew 25 and at its forward end by way of an intermediate member 26 against the joint 27 of a toggle lever arrangement. At the same time the spring 24 tends to press the joint 27 forwardly.
  • This dead point release requires furthermore two strips 28, 29 that form the toggle lever, of which strips 28 are mounted at their outer ends as indicated at 30 in bores 31 in sidewalls 3.
  • the bore 32 of the other link member 29 of unitary construction is entered by the aforementioned guiding pin 20, and thus it follows the movements thereof.
  • a manual release means is provided, which is not illustrated.
  • This heel retainer can be brought from the position in accordance with FIG. 3 by stepping down on the stepping plate 34 and overcoming the dead point, into the holding position in accordance with FIG. 3.
  • the guiding pin 20 slides in the guiding slot 22 of the base and takes along the intermediate housing. Due to the horizontal arrangement of the slots 23 of the intermediate housing it is possible, however, to have a transverse displacement between the intermediate housingand the socket. Furthermore, the slots 23 permit upward rocking of the intermediate housing about the forward linkage 7 as determined by the length of the slot 23. This end position is illustrated in FIG. 5.
  • the manner of operation is as follows:
  • the intermediate housing 2 is firmly held with its forward linkage 7 by the slide 10 in the forward slots 9.
  • the rearward connection 6, however, may rise upwardly.
  • outer and intermediate housing are rockable about this linkage bolt against one another in the manner of a scissors.
  • the intermediate housing can rock with respect to the base portion about the forward link joint 7.
  • catches are provided on the outer housing, which as the rearward end is swung upwardly, engage the intermediate housing and press it upwardly.
  • the present embodiment has guiding bars 35 that are linked at their rearward ends in bores 36 of the outer housing and which are disposed lower, preferably below the bores 18.
  • a linkage pin or rivet 35' is disposed which is slidably guided in slots 37 of the sidewalls 3' that extend generally horizontally. If for crosscountry runs the outer housing is pulled upwardly, then its bore 18 follows an are around the front link 7.
  • the sole-depressing portion 33 With this not only the sole-depressing portion 33 but also the bores 36 carry out a forwardly directed arcuate movement on which is superimposed the rocking movement of the housing about the location 18. This results in that the guiding bars 35 are likewise moved forwardly. Thus their stud 35 comes into engagement with the inclined sliding or running surface 38 of the intermediate housing 2 and thus rocks the same upwardly in counterclockwise direction about the link joint 7.
  • the paths of movement, particularly the curve followed by the soledepressing portion can, therefore, be exactly predetermined by suitable dimensioning of the elements of the assembly.
  • the guiding bars 35 besides may serve, when the binding is used for starts in the position of FIG. 3, for additional latching or as carried along member between the outer and intermediate housing.
  • the outer housing rocks about the rearward linkage 6, i.e., about its bores 18.
  • the guiding bar 35 has imparted to it a forwardly directed movement, so that the stud 35' that is in engagement with the surface 38 tends to move the intennediate housing together with the outer housing upwardly.
  • FIGS. 3 to 5 show a further development of the invention.
  • the sole-retainer portion 33 and the associated stepping plate 34 are unitary, i.e., they are made as a construction element which is linked to the outer housing at the level of the sole-depressing part as at 39.
  • this pivotable structural element there cooperates a guiding arrangement which in the position for cross-country runs with upward movement (depressing) of the'outer housing swings this element rearwardly (forwardly).
  • two pulling bars 40 serve as guidance means, which at their forward ends 41 are linked to the aforementioned structural element at a distance from the location 39 and are pivotably secured at their rearward ends 42 to the intermediate housing.
  • this fastening location is disposed lower than the bores 17 of the rearward linkage 6.
