Definitions

  • the turntable is mounted for rotating motion and carries a safety heel tightener for the purpose of pressing the heel of the boot forwardly against a toe iron.
  • the heel tightener includes a safety feature which permits release when the ski boot or foot experiences an excessive pull.
  • the turntable is provided with a cover plate that clamps to it lbut is easily detachable from it. The longthong is carried by the cover plate.
  • the present invention solves the problem of creating a longthong binding which in spite of the desired firm counection between boot and ski can release the foot in sidewise as well as forward falls by having a turntable, pivoted in the vicinity of the heel but undetachably mounted on the ski, which is equipped with a well-known safety heel tightener of any chosen construction, said heel tightener pressing the foot forward against a front abutment of the binding by means of a thrust member engaging in the heel groove but releasing it under the elect of an excessive pull in a direction approximately vertical to the ski surface, and a cover plate clamped to the turntable but readily detachable and equipped with lugs for the attachment of a longthong.
  • one end of the longthong which is fastened at a point -in front of this end to the corresponding lug of the cover plate may serve as a retaining thong and be connected with one of the thrust members of the safety heel tightener.
  • the cover plate may preferably have some sharpedged ribs running, in their normal position, in the longitudinal direction of the ski, penetrating in the Well-known manner the rubber material of the ski boot heel and causing the cover plate and with it the turntable to follow instantly every rotary motion of the boot without any danger of the heel slipping out of the cover plate.
  • the ribs, by their normal longitudinal direction are o not resisting the forward thrusting force of the heel tightener.
  • the bent-up shackles for the thong lugs can be adjustably attached to the base plate or else a variety of different cover plates may be used for different heel widths.
  • slotted spacers with unequal wall thicknesses can also be used independently from the other features of the invention on heel-clamping devices with shackles for the thong lugs in order to obviate the rather expensive adjustability of the shackle distance.
  • FIG. 1 is a side view of a heel clamping device according to this invention, in the clamping position and with the boot strapped on;
  • FIG. 2 shows the turntable of the heel clamping device according to FIG. 1 with cover plate but without boot and heel tightener
  • FIG. 3 is a side view, in sectional elevation, of the detachable cover plate
  • FIG. 4 is a top plan view of the cover plate
  • FIGS. 5 and 6 are a top plan view and a side view respectively of a spacer.
  • FIGURE l shows the heel-clamping device according to this invention, on the boot in the clamping position, while the FIGURES 2 to 6 are showing the details.
  • the turntable 8 is rotatably attached to the ski 1 in a wellknown and therefore not-further-to-be-explained manner by means of a base plate which is arranged overlappingly in an opening of the turntable 8 and is rmly screwed on to the ski.
  • this turntable is equipped with grooves or ribs 9, arranged consecutively in the longitudinal direction of the ski, onto which the pulling elements 5 and 6, made of wire cable, can be hooked, thus giving lengthwise adjustability by the selection of suitable grooves or ribs 9.
  • the turntable 8 is covered by a cover plate 10 which can be detached from the turntable and is in clamping Contact with the turntable only through the leaf springs 15 and 16.
  • the bent-up ears 17 and 18, 23 and 24 of the cover plate and also a recess 25 that fits into a recess of the base plate (not shown on the drawing).
  • rings 13 and 14 are provided with rings 13 and 14 for fastening the longthong 3.
  • the longthong 3 can be wrapped around the boot 2 with its end 4 beyond the fastening point of the longthong 3 on ring 13 serving as a retaining thong and thus being tied to the pull-cable 5. It is essential that the longthong 3, as the drawing shows, is tied up on the holding ring 13 and not merely drawn through it so that the pull exerted by the longthong does not extend to the pull-cable 5 through the retaining thong 4.
  • the cover plate has ribs 19 to 22 contributing like the recess 25 to the stiffening of the cover plate 10, but even more so for the purpose of securing a rigid torsional connection between the cover plate with the turntable and the ski boot heel, which is usually made of rubber. As shown on FIG. 2 the cover plate 10 also has notches for bringing out the pull-cables 5 and 6 in a satisfactory manner.
  • the foot Under excessive pull, as is apt to occur in a forward fall, the foot is released by the heel tightener 7 in which case the heel tightener, together with its pull cables, remains connected to the turntable 8 and the latter likewise to the ski through its base plate. Due to the easily-detachable clamping connection made by the leaf springs 15 and 16 the cover plate 10 is lifted from the turntable 8 so that the boot, together with the longthong and the cover plate, will be disengaged from the ski and Will retain only a loose connection with the heel clamping device through the retaining thong 4 in order to prevent loss of the ski.
  • either the spacing between the shackles 11 and 12 on the cover plate can be made adjustable or cover plates with different clearances between the shackles 11 and 12 can be provided, so that the cover plate 10 can be exchanged to suit the width of the heel.
  • the first possibility is relatively complicated and therefore expensive, while the second one rcquires an undue amount of storekeeping. It is therefore quite advantageous to slip spacer blocks 26 and 27 on the angular shackles 11 and 12 according to the individual requirements.
  • the spacer blocks are to have slots for attachment and can preferably be made of plastics with different wall thicknesses on each side of the slot so that by omission of the spacer blocks, by the use of only one block and by variation of the wall thickness on the inside of the lugs adjustment for six different widths of the ski boot is possible.
  • a heel-clamping device for safety ski bindings cornprising in combination:
  • a heel-clamping device having one end of the longthong that is fastened on the corresponding thong lug at a spot in front of this end connected with one of the pull cables of the heel safety tightener.
  • a heel-clamping device having a cover plate with sharp-edged ribs running in their normal position in the longitudinal direction of the ski.
  • a heel-clamping device for safety ski bindings with bent-up shackles for thong rings said shackles being attached to a heel plate, particularly according to claim 1, having spacer blocks or strips preferably made of plastics, for adaptation to the heel width, with slots for slipping over the metal strap of the shackles for the thong rings and having wall thicknesses on each side that are different from one another.
