Definitions

  • Ski binding with safety means comprising a vertical bolt, an element in the form of a housing disposed around the bolt which is rotatable around and longitudinally slidable relative to the bolt and adjustable spring biasing means intermediate the bolt and the element for retaining the binding in latched position up to the application of forward fall forces or lateral torsional forces of predetermined magnitude.
  • the invention relates to safety means or devices for ski bindings which are intended for engaging the heel of the ski boot and to release in the event the magnitude of the load or force for which they are adjusted is exceeded, while a part is provided that carries the sole retainer and is displaced in the event of a release action.
  • the safety bindings of this type known heretofore involve the shortcoming of relatively complicated construction and assembly, and therefore they are expensive as well as subject to failure or jamming.
  • a special spring that is separately adjustable.
  • the use of a single spring would also be possible.
  • This heel safety control referred to also as automatic heel release has several advantages.
  • any frictional engagement between the ski boot and the sole plate, or the ski surface is avoided because the sole latch or retainer that seizes the hook in the event of an overload (forward fall) moves upwardly immediately and therefore makes possible the raising of the shoe from the sole plate or the like.
  • the fastening of the shoe to the binding can be effected either by swinging in the shoe from the side, or in that the binding is engaged from the top.
  • one preferred embodiment of the invention provides for the part which is like a housing, a forwardly projecting plate or stepping surface that serves as a support for the heel.
  • the housing-like part in accordance with the invention is also very easily returned by hand into the operating position.
  • a particular advantage of this arrangement resides in that while separately adjustable releases for forward and 3,463,503 Patented Aug. 26, 1969 for torsion falls are made possible, it is very simple and robust in its form of construction and. not readily subject to failure.
  • the number of the necessary structural components is very small which correspondingly decreases the production costs.
  • the housing-like part is suitably the actual housing of the binding proper and can be produced economically by injection molding and therefore be made of plastic.
  • the housing can be made in a manner that it surrounds on all sides the parts which constitute the heel release mechanism and therefore affords protection against entrance of ice and snow.
  • FIG. 1 shows an embodiment of the invention in longitudinal section
  • FIG. 1a is a section taken along line II which shows a modified embodiment of the bolt
  • FIG. 2 is a top view of the device shown in FIG. 1;
  • FIG. 3 is a further modified embodiment of the inven tion also in longitudinal section.
  • FIG. 4 is a further development of the embodiment in accordance with FIG. 3 partially in section taken along line IVIV.
  • the ski 1 or its base plate 2, or the like, has mounted on it a bolt or stud 3.
  • the part 4 which is in the form of a housing (hereinafter referred to merely as housing) is longitudinally slidable relative to this bolt 3 and pivotally movable.
  • a sliding sleeve 5 made preferably of steel, can be fastened in the housing, for eX- ample, by pressing.
  • a sole retainer 6 which can preferably be adjustable in height, which in the position of operation engages the upper edge 7 of the rearward part of the sole or boot and thus retains the boot, the heel of which is identified at 8.
  • the housing 4 thus has the function of a pressure member which effects the release of the boot under application of suitable pressure, while the bolt or stud 3 serves as a .stop or latch.
  • the point of the boot can advantageously be held by a very simple front jaw because all protection devices against fall are provided by the heel release mechanism.
  • the housing 4 is pusher upwardly along bolt 3 against the effect of the vertical latch means which include the spring 9, while with an excessive torsion force, such as a twisted fall, it swings about the bolt 3 against the effect of the pivot latch means which include the spring 10.
  • the springs 9, 10 which are separately adjustable by adjusting members 11, 12 respectively force suitable ratchet means such as balls 13, 14 into recesses in the bolt 3.
  • the recesses may, in accordance with this embodiment, be defined by an annular groove 15 and a longitudinal groove 16.
  • the groove 16 is made so long that the ball 14 can move sufliciently upwardly in the event of a forward fall release. In this event the ball 13 is pressed out of the annular groove 15 into the guiding cylinder of the spring 9 so that the housing 4 can be displaced upwardly along the bolt and thus free the boot.
  • the ball 14 is pushed out of the groove 16 into the guid ing cylinder for the spring 10 so that the housing 4 can move pivotally.
  • the recess or groove 15 in accordance with FIG. 1, or the part of the bolt provided there, is so constructed that also the ball 13 can yield laterally. This is already made possible by the use of the aforementioned annular groove 15.
  • the part 3' of the belt which forms the counter-bearing for the ball 13 could have such a cross section that the ball with pivotal movement of the housing moves out of the range of the effective counter-bearing surface.
  • the location of this cavity or flattening 17 is indicated in dot and dash lines in FIG. 1.
  • the housing is automatically freed in longitudinal direction. Since the permissible forward load is normally greater than the permissible torsion load, it is advisable to have the diameter of the ball 13 and the force of the counter spring 9 correspondingly larger than the diameter of the ball 14 and the force of the spring 10.
  • the sole holder 6 is in accordance with a preferred embodiment of the invention linked to the housing 4 as at 18, and after a forward fall release as well as corresponding upwardsliding of the housing can be moved pivotally in the direction of the end of the ski.
  • it may have. a nose 19 which when the forward fall safety element is not released rests against the upper end 3" of the bolt, but overreaches this bolt end after release and shifting of the housing as indicated in dot and dash lines.
  • This displaceable arrangement of the sole retainer has the advantage that already with the upward shifting of the housing by a small amount a faultless release of the hook is achieved whereby the structural height of the entire heel release mechanism is correspondingly reduced.
  • a roller 20 may be provided between these two parts which is preferably secured to the nose 19 of the sole retainer.
  • the sole retainer supports itself on the bolt by way of the roller.
  • the roller rolls on the bolt upwardly until it has reached its upper cap and the sole retainer swings by an angle of about 90 over the bolt and fully frees the boot.
  • an additional spring (not shown) can be introduced between the sole retainer and the housing which has the tendency to press it against the upper edge of the heel and thus into position of operation.
  • the housing in such a manner that it extends over the bolt from the top and covers it.
  • the side wall of the housing must be provided with an aperture, for example, a slot for the lug or nose of the sole catch.
  • the aperture above the bolt may, as illustrated, also be covered by a flap of plastic material or the like.
  • a forwardly facing step plate 21 which serves as a support for the heel is provided on the housing.
  • This plate serves simultaneously as a stepping plate for returning the housing after a forward fall release against the force of the spring to position of use, where the heel safety release presses the boot firmly against the forward jaw or the like.
  • the sole catch 6 swings automatically from the release position (dash and dot lines, FIG. 1) into the position of use (solid lines).
  • To facilitate this its bottom side may be provided with a rearwardly and upwardly extending inclined surface 6.
  • the lateral checks 4' of the housing may be provided with rollers 22 (FIG. 2).
  • holders 23 for the long strap may be provided.
  • FIG. 3 shows a simplified embodiment of the catch means.
  • a ball 24 is provided which engages a cap shaped recess 25 in the bolt 3 and thus serves as a lateral or rotational as well as a forward fall guard.
  • the counter forces cannot be ad justed separately because only a single pressure or biasing spring 26 is provided.
  • FIG. 4 shows still a further development of the embodimentin accordance with FIG. 3.
  • a recess or annular groove 27 is provided which extends completely or partly about its circumference in which the indentation 25 for the accommodation of the ball 24 is located.
  • a release lever 28 is. provided which is pivotably supported on the housing or on the base plate. It has one arm that extends .rearwardly from thesafety release mechanism where. it has an indentation for seating the point of the ski pole. .As soon as this end of .the lever 28 is pressed down, itsother end engages the catch ball for the forward fall and displaces the ball far enough'to permit the housing to slide upwardly. It is, of course, understood that this lever canalso be employed inthe embodiments shown in FIGS. 1, la and 2.
  • additional means can be provided, such as latches or abutments which limit the lifting movement of the housing.
