Definitions

  • the invention relates to a ski binding having a cable extensible by means of a front tightener and embracing the heel of the boot.
  • a release element brings about the automatic opening of the front tightener by cooperation with a movable component of the front tightener.
  • the release element can press from below on to a movable part of the front tightener so that the front tightener is moved or rocked into its opening position.
  • a release element moving when overstrain occurs on the cable can cooperate, for example, with the tightener lever, or with the tension member of the front tightener in which the encircling cable of the ski binding engages directly or indirectly and which is pivotally connected in manner known per se to the front tightener.
  • the release element can cooperate with the rod.
  • the release element can, however, also be disposed on the rod. In this case there is the advantageous possibility of dividing the helical spring known per se and disposed on the rod into two pieces, the opening agent lying between the two parts of the spring. It is possible further to regulate or adjust the sensitivity of the releasing gear by the length of the two parts of the helical spring.
  • Figures 1 and 2 show a complete binding arranged on a ski, respectively from the side and from above.
  • Figure 3 shows to a larger scale the front tightener according to Figures 1 and 2 in the closed position, seen from the side.
  • Figure 4 shows a cross section taken on line 44 in Figure 3, the cable rod being omitted.
  • Figure 5 is a longitudinal sectional view taken on line 5--5 of Figure 2.
  • Figure 6 shows another construction of a front tightener arranged on the ski, seen from the side in partial section.
  • the ski binding in Figures 1 to 4 consists of the cheeks 2 connected firmly to the ski 1 and the encircling cable 3, the front end of which is connected to the front tightener.
  • the front tightener itself consists of the base plate 4 screwed fast to the ski 1, which base plate in the example illustrated is formed at the front into a U-shaped guide 4'.
  • the tightener lever 5 is rotatably connected to the two laterally turned up flanges 4 of the base plate 4 by small bolts or rivets 6. In the rear forked part of the tightener lever there engages a tension member 7, which is pivotally connected by small bolts or rivets 8 with the tightener lever 5.
  • the front part of the tightener lever 5 is of U-shaped cross-section open at the bottom.
  • a helical compression spring 9 which is disposed on a rod 10 guided in the member 7.
  • the rod 10 is connected at the back in any suitable manner to the cable 3 and has a rotatable nut 11 at the front, which forms a thrust support for the helical spring 9.
  • the front end of the rod 10 is guided. in the guide 4' of the base plate 4 by means of a slide 12 in the longitudinal direction of the ski.
  • the cable rod 10 extends through a hole in the vertically disposed flange 12 at the rear end of the slide 12.
  • the slide 12 is constructed as a release element.
  • the slide 12 has at its front end a flange 13, for example bent upwards vertically, which, as is clear from Figure 3, is curled over at the top or is provided with an abutment 14in any other suitable manner.
  • the abutment 14 corresponds in width at least'to that of the tightener lever 5, as is clear from Figure 4. It can also be seen from Figure 4 that the parts 13, 14 of the slide are provided in their centre with a recess 15 to allow the passage of the cable rod 10 when this extends farther forwards than is shown in Figure 3 in the case of a greatly tensioned spring.
  • FIGS. 6 and 7 show another form of construction.
  • a slide 17 likewise constructed as a release element here cooperates with the tension member 7, instead of with the tightener lever 5.
  • the vertically disposed flange 17, accommodating the hole for the cable rod 10, at the rear end of the slide 17 is provided at the top with a bent over edge 17", which corresponds in width at leastl' to the width of the tension member 7.
  • the helical compression spring disposed on the rod Ill' is divided into two parts 9*, 91', between which the vertical flange 17 ofthe slide 17 isdi'sposed, that is to say, the two ends facing, one another of the helical spring parts are both, supportedon the release element. Since the release element is slidable, the entire length ofthe two parts ofth'e spring 9', 9" is available for the tension of the cable. v
  • an elastic shock absorber 18 can be fixed on the top of the tension member 7 in any suitable manner. T he edge indicated by 5 of the tightener lever 5 strikes against this shock absorber, as shown by the dashed line in Figure 6.
  • the position of the release element in the position of rest can be determined or varied, so that there is the possibility of regulating or adjusting the size of the release path and thus the sensitivity of the entire release gear.
  • the part 9' of the spring situated at the front could naturally also be omitted if the length of the part 9" of the helical spring is suflicient.
  • a ski binding comprising a cable engageable around the heel of a boot, a lever pivotable on a fixed axis for tightening said cable about said boot heel, a tension member pivoted on said lever about an axis parallel to the piv otal axis of the lever, a cable release element slidable longitudinally of the ski, a rod attached to the front end of said cable and guided in said tension member and said cable release element, compression spring means interposed between said tension member and said cable release element, and means for coupling said rod to said cable release element, the lever and the tension member together forming a device by which the cable can be automatically locked in its tightened condition, and said release element being engageable, in the event of overstrain on the cable, with cam means associated with said cable locking device thereby to rock said lever and ten sion member in a direction to release the lock on the cable.
  • a ski binding comprising a cable engageable around the heel of a boot, a lever pivotable on a fixed axis for tightening said cable about said boot heel and having camshaped edges thereon, a tension member pivoted on said lever about an axis parallel to the pivotal axis of the lever, a cable release element slidable longitudinally of the ski, a rod attached to the front end of said cable and guided in said tension member and said cable release element, a helical compression spring coiled about said rod and interposed between said tension member and said cable release element, and means for coupling said rod to said cable release element, the lever and the tension member together forming a device by which the cable can be automatically locked in its tightened condition, and said release element being engageable in the event of overstrain on the cable, with the said cam-shaped edges of said lever thereby to rock the lever and the tension member in a direction to release the lock on the cable.
