Definitions

  • ABSTRACT A releasable ski binding of the type incorporating a release plate anchored at the ski to be releasable to all sides, the release plate being retained at least at its one end by a spring-loaded locking element.
  • the locking element is pivotably mounted about an axis extending transversely with respect to the lengthwise direction of the ski, and under the action of its spring, in the normal position of the release plate, bears upon a central section or region of a guide track.
  • the guide track possesses to both sides of such central region step-like and/or continuously raised sections.
  • the present invention relates to a new and improved construction of releasable ski binding or safety ski binding of the type incorporating a release plate anchored at the ski so as to be releasable to all sides, the release plate being supported at least at one of its ends by means of a springloaded locking element.
  • this release binding is manifested by the features that the locking element is pivotably mounted about an axis directed transversely with respect to the lengthwise direction of the associated ski.
  • the spring-loaded locking element under the action of its associated spring, in the normal position of the release plate, bears upon a central region or section of a guide track, and this guide track is provided to both sides of such central region or section thereof opposite the same with step'like and/or continuously raised sections.
  • FIG. 1 is a perspective view illustrating one end, such as the rear end of a release plate and its anchoring arrangement;
  • FIG. 1A is a perspective view illustrating the front end of-the release plate and its anchoring arrangement
  • FIG. 2 is a side view of a portion of the arrangement depicted in FIG. 1;
  • FIG. 3 is a cross-sectional view of the showing of FIG. 2, taken substantially along the line Ill-III thereof;
  • FIGS. 4 and 5 illustrate a variant embodiment of the invention, corresponding to the showing of FIGS. 2 and 3 respectively;
  • FIG. 6 is a plan view of a further variant construction of the invention.
  • the front bearing plate 4 is pivotably mounted at a pivot shaft or axis 6, as best seen by referring to FIG, 2, directed transversely with respect to the lengthwise direction of the associated ski.
  • This bearing plate or bracket 4 carries a forwardly extending springloaded locking element 7, here in the form of a pin 8.
  • the release plate 2 carries at its rear end an upwardly protruding web or bracket 13,. the upper edge of which forms a guide track 14 which descends from its central section or region 14a to both sides thereof, as clearly shown in FIG. 1.
  • the follower roller 9 of the locking element 7, under the action of the spring 12 bears upon the central region 14a of the guide track 14.
  • this central region 14a of the guide track 14 possesses in the exemplary embodiment under consideration, an engaging notch or groove 15.
  • the track 14 has a step-like configuration, wherein the track sections bounding the central notched section are initially raised in step-like fashion and then extend upwards in a smooth continuous course.
  • the notch could be, of course, omitted to provide a completely continuous raised track.
  • the rear end of the release plate 2 is supported to be laterally movable or shiftable on the ski (in this figure indicated by reference character 16) through the agency of the rollers 17.
  • these rollers 17 could serve to retain the release plate 2 in the lengthwise direction of the skinln such case, they would have to be form-lockingly connected with the ski, that is to say, cooperate with a front and/or rear guide.
  • the same purpose could be of course fulfilled, among other things, by means of a plug pin of thetype indicated in FIG.
  • the locking element 7 under the action of the spring I 12, retains the release plate 2 and in any event its rear end in the illustrated normal position. After overcoming the spring force the rear end of the release plate 2 can, however, be moved to both sides and/or upwardly away from the surface of the ski, wherein at the same time the locking element 7 is upwardly rocked.
  • the roller 9 initially departs from the notch or groove 15 and then subsequently rolls upon one of the respective neighboring ascending lateral sections or portions 14b of the guide track 14. This arrangement allows for considerable freedom in influencing the lateral release action of the binding.
  • the locking element 7 retains the rear end of the release plate 2 in contact with the ski as a function of the spring force. If this holding force is exceeded, then the rear end of the release plate 2 lifts-off the ski and at the same time the locking element 7 is rocked upwards.
  • the release plate 2 is only then released when the locking element 7 comes out of engagement with the guide track 14.
  • the effective length of the locking element 7 is decisive.
  • the guide track particularly as the same has been shown in FIG. 5, can be completely or partially formed by a roller 19 which is tapered at its central section, and which is rotatably mounted at the web 13' of the release plate, the guide track in this case being continuously and smoothly raised and designated by reference character 14'.
  • This roller 19 can be of course much longer than has been illustrated.
  • the roller 19 will be designed to be relatively short, and particularly then when it is desired to impart to the flank or portion 30 of the guide track 14' merging therewith a particular course, for instance inclined towards the front i.e. deviates back starting from the region of its central section, in the lengthwise direction of the release plate.
  • a particular course for instance inclined towards the front i.e. deviates back starting from the region of its central section, in the lengthwise direction of the release plate.
  • a releasable ski binding comprising a release plate capable of being anchored to the ski so as to be releasable to all sides, a spring-loaded locking element for releasably holding at least one end of the release plate against the ski, means for mounting the spring-loaded locking element to pivot about an axis directed transversely with respect to the lengthwise direction of the associated ski, said spring-loaded locking element being provided with a roller, a guide track mounted on the release plate, said guide track being provided with a roller defining at least a central section of the guide track, the spring of said spring-loaded locking element urging said locking element in the normal position of the release plate to bear via its roller against the roller defining the central section of the guide track, said central section of the guide track being bounded to each side by a raised section.
  • roller defining at least the central section of the guide track is tapered at its central region, and means mounting said tapered roller at the release plate for rotation about an axis directed transversely with respect to the lengthwise direction of the release plate.
  • a releasable ski binding as defined in claim I wherein said guide track includes a portion which deviates back, starting from the region of its central section, in the lengthwise direction of the release plate.
  • a releasable ski binding as defined in claim 1 further including roller means for displaceably supporting 6 the release plate towards the side at the ski at the re the release plate in the lengthwise direction of the ski. g of the gu'de track- 8.
