Definitions

  • a skl safety device for releasably attaching Skl boots to SklS Feb. 12, 1969 France ..6903231 comprises boot heel gripping means on one end of a lever mounted for both vertical and horizontal pivotal movement in [52] 11.8. C1 ..280/1 1.35 T relation to the plane of the ski.
  • a continuous pressure is ap- [51 rm. Cl ..A63c 9/00 plied against the other end of the lever 50 that the pp 58 Field of Search ..2s0/11.35 T means is mmally maintained a gripping but can be knocked horizontally or vertically to a boot freeing position.
  • the present invention relates to devices for releasably attaching skis to ski boots while allowing these two components to separate in the case of a fall, shock, or abnormal pressure.
  • most known safety devices comprise one safety device called the toe clip placed on a ski in front of the boot and another safety device called the heel clip behind the boot.
  • the device according to the invention is a heel clip offering the same degree of safety in case of accident as the known toe clip and heel clip combinations. There is thus obtained a reasonably priced fixation in a compact and strong unit, and which can be simply maintained.
  • the attachmentdevice according to the invention resolves this problem by eliminating slipping of the boot on the ski in case of accidents, and taking the maximum advantage of the decrease in the skiers pressure on the heel.
  • the invention provides a safety heel clip in which upward vertical forces on the heel and forces on the heel horizontally in both directions and in all oblique directions are opposed by means providing one or more opposing forces which can be exerted up to certain values, above which sudden and total freeing of the boot is caused.
  • FIG. 1 is a side view, partly in cross section of a heel clip according to the invention with a boot placed on a ski in the normal position.
  • FIG. 2 is a plan view of the same heel clip in the normal position.
  • FIG. 3 is a view similar to FIG. 1 but with the heel of the boot subjected to a lifting force.
  • FIG. 4 is a view similar to FIG. 2 but with the heel of the boot subjected to a lateral force.
  • FIG. 5 is a side view, partly in cross section of another embodiment of the heel clip according to the invention.
  • FIGS. 1 and 2 only the heel end 1 of the ski boot is shown.
  • the entire length of the boot rests on a metal plate 2 permanently fixed on ski 3.
  • the heel clip fixation device according to the invention is connected to a support member which is releasably attached to the ski by means of four screws 4.
  • the safety device comprises a unit composed of parts 5, 6, and 7 pivotally fixed to one another in order to be able to tightly grip the heel of the boot according to the shape thereof, and to be firmly fixed together to prevent any subsequent free play. Details of this pivotal fixation are well known and have not been shown.
  • All three parts 5, 6, and 7 are connected by a screw 8 to a crank lever 9 bearing a cylindrical pin 10 around which it is able to pivot, and to a group of antifriction members comprising three freely rotating rollers ll, 12, and 13.
  • Bearings 14 and 15, on which the ends of pin 10 pivot join a part 16 around the crank lever 9 and bearing two pivotally mounted shafts 17 and 18, at right angles to the pin 10, freely pivoting at one end in a hole of a body 19 fixed to the ski and at its other end in a bearing 20 fixed to the same body 19 but on the opposite side thereof.
  • the part 16 constitutes the component commonly called the Cardan joint."
  • the lever 9 is free to rotate in any direction, both around the pin 10 and around the shafts 17 and 18, thus forming a Cardan transmission.
  • Screw 8 serves to adjust the rest position of the lever 9, in relation to the thickness of the heel of the boot, as is well known.
  • the body 19 consists of a substantially tubular prismatic part the inside faces 21, 22, 23, and 24 of which form planar bearing surfaces. In the interior space defined between these walls a part 25 can freely move by means of a suitable number of ball bearings or rollers 26.
  • Part 25 has a bearing surface 27 against which rollers 11, I2, and 13 of the crank lever 9 always press as the part 25 is pushed against these rollers by an opposing force supplied, for example, by a compression spring 28 compressed as desired by a threaded stopper 29, which can be screwed into a cylindrical tail part of the body 19.
  • the system works in the case of shocks, falls or abnormal pressures, as is shown in FIGS. 3 and 4.
  • the heel tends to lift up following a frontal shock, for example.
  • the force of inertia added to the weight of the skier must be sufficient to be able to overcome the resistance offered by the opposing force of the spring 28 on the part 25 and hence roller 12.
  • the heel of the skier raises, pivoting the lever 9 in a clockwise direction in a vertical plane (looking at FIG. 1) and the roller 12 runs over surface 27 which is inwardly curved at 30 and facilitates the pivotal movement of the lever.
  • the lever 9 is then immobilized in an unlocking position shown in FIG. 3, thus totally freeing the heel and the boot.
  • the heel is subject to an exterior force, shock or fall, moving it towards the left of the ski in a horizontal plane
  • spring 28 always acts on the rollers ll, 12, and 13 to provide an opposing force. If this opposing force is insufficient to compensate for the exterior forces, the heel grip will open and free the boot.
  • FIGS. 1 and 2 In order to fit the boot to or remove it from the ski, an equally simple and original device is provided as can be particularly seen in FIGS. 1 and 2.
  • a shaft 31 of generally cylindrical shape is rotatably mounted in two bearings provided in the body 19 and has a cutout middle portion leaving a flat surface 32 (FIG. 1).
  • a lever ending in a bent over part 34 is attached to an end 33 of the shaft 31 outside the body 17.
  • the skier can turn the shaft 31 by depressing part 34 by hand or with the end of his ski stick.
  • the surface 32 acts as a lever on a small movable plate 134, held by the spring 28 contained in a housing in part 25. Rotation of the shaft 31 thus causes cancellation of the effect of the spring 28 on the lever 9 which is thus freed and enables the skier to remove his boot from the ski by lifting his heel.
  • FIG. shows another embodiment of the safety heel clip according to the invention.
  • the gripping component 40 for the boot comprises a semispherical part 37 the flat planar end of which cooperates with a planar surface of a thrust piece 36 also having a semispherical configuration.
  • the flat end face or pressure face of the part 37 is provided with an antifriction device, ball bearings 38 for example.
  • ball bearings 38 for example.
  • the cooperating faces of parts 36 and 37 could be coated with a synthetic material such as polytetrafluoroethylene which enables satisfactory sliding of the surfaces.
  • a spring 28 exerts a biasing force on the first piece 36 opposed to the pivoting movement of the holding component 40 about the center ofa swiveljoint 39.
  • a device for releasably fixing the heels of boots to skis comprising: a support, means for attaching said support to a ski, a lever having first and second ends, means mounting said lever on said support intermediate said first and second ends for pivotal movement at least about axes horizontal and vertical in relation to the surface of a ski upon which the device is to be fixed, boot heel gripping means on said first end of said lever, pressure applying means including a bearing surface for applying said bearing surface against said second end of said lever, slide-permitting means between said second end and said bearing surface for permitting said second end to slide horizontally and vertically against said bearing surface, said pressure means normally urging said lever so that said first end normally assumes a boot-gripping position and said pressure means urging said lever to cause said first end to assume a horizontal and/or vertically displaced boot-freeing position whenever said first end if upwardly displaced beyond a limiting value of sidewardly displaced beyond a limiting value.
  • said second end of said lever carries one roller having a horizontal axis and two rollers having vertical axes.
  • a device wherein said bearing surface has means defining a recess in which said horizontal roller is housed when in said vertically displaced boot-freeing position.
  • a device wherein said bearing surface is located on a thrust piece longitudinally movable in said support and guided by ball bearings or rollers.
  • said pressure applying means is a compression spring compressed and disposed between a positionally adjustable part of said support and said thrust piece.
  • said slide-permitting means is a plate coated with a synthetic material on either or both of said surfaces.
  • a device for releasably attaching the heel of a ski boot to a ski comprising: a support member; means for connecting said support member to a ski; a lever having first and second end portions; means mounting said lever intermediate said first and second end portions on said support member for pivotal movement in both vertical and horizontal planes between a common locking position and a plurality of unlocking positions; boot heel gripping means connected to said lever at said first end portion for releasably gripping the heel of a ski boot when said lever is in said locking position; and force applying means for continuously applying a force of a predetermined magnitude to said second end portion of said lever to maintain same in said locking position and responsive to a predetermined extent of pivotal movement of said lever in one of said planes to effect further movement of said lever in that plane to thereby move said lever to one of said unlocking positions.
  • said force applying means comprises a movable bearing surface, a plurality of antifriction members rotatably mounted on said second end portion of said lever at least one of which is rotatable about a vertical axis and at least one of which is rotatable about a horizontal axis, and spring means continuously biasing said bearing surface into contact with said antifriction members to thereby apply said force through said antifriction members to said lever.
