Definitions

  • ABSTRACT Releasable ski binding permitting longitudinal movement of the ski boot with respect to the ski.
  • One binding such as the rearward binding, grips a suitable fitting on the ski boot in a conventional manner both above and on both sides thereof and is arranged for resiliently opposed release upon either upward or sideward movement of the associated end of the ski boot.
  • the toe of the boot is provided with a single longitudinally aligned pin which projects into said recess, preferably received into the upper portion thereof, to permit longitudinal motion between the pin and the fitting but to prevent motion in any direction perpendicular thereto.
  • the invention relates to a ski binding consisting of a front and rear binding part each of which cooperates with a fitting which is arranged on the ski boot or on a bottom plate carrying the ski boot.
  • the purpose of the invention is to overcome this disadvantage and the invention is characterized in that one fitting is constructed as a pin arranged longitudinally of the ski, which pin is supported during use in a recess provided in a guide part secured on the ski and the other fitting is as is now conventional gripped over and held by the associated binding part from the side and from above.
  • This construction effects a release both during a fall forwardly and also during lateral excessive stresses only through the last-named binding part.
  • the other binding part is used only for guiding the pin-like fitting. If the ski bends during skiing, then the pin can slide longitudinally in the recess of the guide part. Thus there is no spring loading and as a result the holding power of the other binding part is not changed in any way.
  • FIG. 1 illustrates the entire arrangement of a ski boot on the ski
  • FIG. 2 is an enlarged, partially longitudinally sectioned view of the front holding means
  • FIG. 3 is an end view of FIG. 2,
  • FIG. 4 is a top view of the rear holding means
  • FIG. 5 is a cross-sectional view along the line VV of FIG. 4 and FIG. 6 is a top view similar to FIG. 4 partially in a cross-sectional view during the instant of a lateral release.
  • FIG. 1 the ski boot 16 is secured on a sole plate 6 in a conventional manner.
  • Binding parts 18, 19 are mounted onthe ski 17, which binding parts grip fittings 5, 15, respectively, of the sole plate 6 and thus hold the ski boot 16 on the ski 17.
  • the rear ski binding part 18 grips from the side and from above over the fitting 5 in such a manner that the sole plate 6 cannot move longitudinally of the ski.
  • the front ski binding part 19 is constructed as a guide part as best shown in FIGS. 2 and 3.
  • An equilateral triangle shaped recess 20 is provided in this guide part 19, in which recess and pin-shaped fitting 15 is guided only in the upper area.
  • the recess 20 enlarges downwardly so that the fitting 15 can swing downwardly or to the side during a fall forwardly or during a twisting fall when the rear binding 18 releases.
  • the fitting 15 is in a simple manner introduced into the recess 20 and the rear fitting 5 then engages the rear binding part 18.
  • the pin 15 can slide in the recess 20.
  • the front guide part can be made either entirely, or at least in the zone of the recess, of an elastic material, for example plastic, rubber or the like.
  • an elastic material for example plastic, rubber or the like.
  • a sleeve containing the recess 20 and being made of elastic material could be inserted into the part 19.
  • FIGS. 4 to 6 substantially of two levers, l, 2 which are loaded by the springs 3, 4 and which with their angled ends grip over the boot fitting 5 both from the side and also from above.
  • the boot fitting 5 is constructed as a double-conical swivel plate which is secured on the sole plate 6.
  • the springs 3, 4 press the levers 1, 2 against two posts 7, 8 which are fixedly anchored on the base plate 9.
  • a disk 10 is secured at the upper end of the posts 7, 8.
  • the springs 3, 4 abut the one ends of support arms 11, 12 which are supported with their other ends on the levers l, 2. In their central zone the support arms 11, 12 are held against the levers 1, 2 through the screw 14 and the nut 13.
  • FIG. '6 shows the sole plate 6 moved to the side.
  • the levers 1, 2 are thereupon also pivoted. Since the posts 7, 8 are positioned between the levers this movement urges the levers apart against the force of the springs 3, 4.
  • the illustration shows the moment of the release. If a force occurs in an upward direction, for example due to a fall forwardly, then the fitting 5 is pulled upwardly and the two levers 1, 2 are similarly moved apart.
  • FIG. 5 shows in cross-sectional view how the two levers l, 2 grip from above over the fitting 5.
  • a ski binding having a front and a rear binding part mounted on a ski each being adapted to cooperate with means on one of a ski boot and a bottom plate on which a ski boot is mounted for effecting a releasable securement of one of said ski boot and said bottom plate to said ski
  • one of said front and rear binding parts includes means defining an elongated pin mounted on one end of one of said ski boot and said bottom plate and extending parallel to the longitudinal axis of said ski and means defining a recess mounted on said ski and adapted to receive said pin therein for longitudinal sliding movement with respect thereto
  • the other of said front and rear binding parts includes securement means (I) for releasably holding the other end of one of said ski boot and said bottom plate against at least a lateral movement and (2) for preventing a longitudinal movement of one of said ski boot and said bottom plate relative to said ski whereby the permitted relative movement between said pin and said recess means will thereby facilitate a bending of said ski
  • said means defining a recess includes means made of an elastic material at least surrounding said recess.
  • said recess includes means defining an upper narrow region and a wide lower region
  • pin means is positioned in said upper narrow region when said one of said ski boot and said bottom plate are longitudinally aligned with said longitudinal axis of said ski.
  • securement means is also adapted to releasably secure said other end against a vertical movement.
  • first and second longitudinally spaced binding parts mounted on a ski and on opposite ends of said ski boot means to effect an engagement of the ends of said ski boot means with said ski;
  • one of said first and second binding parts including means defining an elongated pin extending parallel to the longitudinal axis of said ski and means defining a recess adapted to receive said pin means therein for longitudinal sliding movement with respect thereto, for releasably holding one of said ends of said ski boot means on said ski, said pin means being mounted on one of said ski and said ski boot means and said means defining a recess being mounted on the other of said ski and said ski boot means; and
  • the other of said first and second binding parts including securement means (1) for releasably holding the other of said ends of said ski boot means remote from said one of said first and second binding parts against at least a lateral movement and (2) for preventing a longitudinal movement of said ski boot means relative to said ski.
  • a releasable ski binding according to claim 8 wherein said first binding part engages the toe end of said ski boot means and said second binding part engages the heel end of said ski boot means.
