Definitions

  • the invention relates to a release ski binding with a pivotable in its central region about an approximately vertical vertical axis and a transverse plate, seen from the ski tip and arranged in front of the vertical axis, which can be folded up in the driving position by a holding device opened by a release spring Ski is held, the latter 'depending on the pivoting movement of the sole plate with respect to the ski when reaching a predetermined pivoting angle both upwards and to the side causes a holding mechanism to open.
  • Such release ski bindings are described in DE-PS 25 33 337.
  • the spring of the holding device acts via a piston on an approximately mushroom-shaped follower which is pivotally mounted on all sides in the housing of the holding device. This mushroom-shaped follower engages with its handle in a recess of a ski-proof fitting.
  • the ski boot is held at the tip by means of a rigid bracket on the soleplate. In the event of the skier falling backwards, the ski boot is therefore very difficult to release.
  • the invention sets itself the goal of eliminating the disadvantages of the known designs and a release ski binding of the ge to create named type, which allows simple in their structure / and a very precise setting of the desired triggering moments in the event of a frontal fall and a turning fall.
  • the holding mechanism has two pairs of clamping jaws which engage on the side of the ski boot, which are designed as two-armed levers, are mounted on the soleplate and are inserted into the soleplate by a slide plate which is guided on the soleplate and provided with wedge-shaped projections Clamping position can be brought, wherein the slide plate is coupled by means of a control lever with a step bracket mounted on the sole plate.
  • kick bars for ski bindings.
  • the kick bar is only used to pivot the two brake mandrels from their braking position upwards over the level of the upper side of the ski when the ski shoe is being put in, and at the same time the ski shoe both in the longitudinal direction direction as well as in the cross direction of the ski.
  • the holding elements for the ski boot are not actuated by the kickbar.
  • the invention provides that the axis for the kick bar is arranged in the region of the end of the sole plate facing the ski tip. This measure simplifies the entry of the ski boot into the ski binding in that the relative movement between the tip of the ski boot and the ski is substantially reduced compared to the reverse arrangement (arrangement of the kick bar axis at the end of the sole plate facing the end of the ski).
  • control lever is designed according to the invention as a two-armed lever which is mounted in the soleplate and the upper end of which is guided by means of a roller in guides which are located on the underside of the kickbar. In this way, a large lever ratio can be brought about and the force required for the adjustment of the slide plate can thus be greatly reduced.
  • the lever arm of the control lever opposite the roller is fork-shaped and provided with two inner prongs and two outer prongs.
  • the function to be performed by the control lever is divided into two pairs of elements, one pair only displacing the slide plate towards the end of the ski, the other pair, however, initially adjusting the slide plate towards the ski tip and then abruptly displacing the slide plate should bring into the clamping position.
  • the control lever In order to facilitate the opening of the ski binding, according to the invention are on the top of the slide plate two bearing blocks attached, in which a bolt is guided in the longitudinal direction of the ski, which is under the influence of a spring to push it towards the end of the ski.
  • another feature of the invention also aims for the control lever to be provided with a nose on its end that carries the roller, which nose is used to engage the bolt in the ski binding's driving position.
  • the slide plate could be provided with approaches for attacking the two pairs of tines.
  • the slide plate between the bearing blocks is provided with a preferably approximately T-shaped recess in plan view, into which the four prongs of the control lever engage when the ski binding is in the entry position.
  • the slide plate is releasably connected to the resilient holding device via at least one one-armed locking lever, which, as is known per se, is accommodated in an extension of the sole plate.
  • the retaining spring is used to act on the slide plate, which therefore has to fulfill two functions simultaneously. This leads to a certain simplification of the construction.
  • the slide plate is fork-shaped at its end adjacent to the holding device and carries a roller on each fork prong, which in the driving position of the ski binding bears against a shoulder of the associated locking lever which runs transversely to the longitudinal axis of the ski.
  • the two rollers significantly increase the accuracy with which the ski binding opens when the set release torque is reached, since the friction between the slide plate and the two locking levers is greatly reduced by the rollers.
  • the invention provides that at least one articulated bracket with one end is arranged on the axle, the other end of which is articulated on a release lever which is mounted in the base of the soleplate and is designed as a two-armed lever.
  • a one-armed lever is mounted on the axle for the intermediate lever, which lever has a cam on the piston in the bore rests on the soleplate and is acted upon by the spring of the holding device on the opposite side.
  • the trigger spring is accommodated in a spring housing which can be pivoted about the axis for the latching lever or latches, the axis being displaceable approximately in the longitudinal direction of the ski in at least one slot.
  • a piston acted upon by the release spring is guided in the spring housing, which carries a roller on its side facing away from the release spring, which is intended for contact with the lever.
  • Slider plate consists of at least two plate-shaped parts which receive the wedge-shaped shoulders between them and by rivets or the like are connected.
  • FIG. 1 is a section along the line I - I in Fig. 2
  • Fig. 2 is a plan view of the ski binding with the kick bar depressed
  • Fig. 3 is a section through the holding device along the line III - III in Fig. 5
  • Fig. 4 shows a section through the holding device along the line IV-IV in FIG. 5
  • FIG. 5 shows a plan view of the holding device with the housing cover removed
  • FIG. 6 shows a section along the line VI-VI in FIG. 2.
  • FIGS. 7 and FIG. 8 shows a detail of the ski binding in longitudinal section or in section along the line VIII-VIII in FIG. 7 on a larger scale.
  • a hold-down device 1a On a ski 1, three holding elements are fastened, namely a hold-down device 1a, a central bearing pin 1b and a bearing block 1c for a follower 2.
  • a sole plate 3 above the ski 1. This has a transverse upper support strip 3a at its front end, at a distance from this a lower support bar 3b parallel to the first support bar, further. a receiving hole 3c for the bearing journal 1b and a lug 3d in which a holding device 4 is accommodated.
  • two pairs of clamping jaws 5 are mounted so as to be pivotable about longitudinal axes 5a (see FIG. 6). Each jaw 5 is designed as a two-armed lever.
  • a step bracket 6 is pivotally mounted on an axis 6a.
  • the kick bracket 6 is under the influence of a spring 6b designed as a leg spring.
  • the kick bar 6 has on its underside one in its longitudinal direction-extending guide 6c, in which a roller? a is guided, which is mounted on the end of a control lever 7.
  • This end carries a nose 7e.
  • the control lever 7 is designed as a two-armed lever and can be pivoted about an axis 7b mounted in the soleplate 3.
  • the lever arm opposite the roller 7a is fork-shaped by carrying two longer inner tines 7c and two shorter outer tines 7d (see FIG. 8), the purpose of which will be explained later.
  • a slide plate 8 is guided. In plan view, this carries wedge-shaped lugs 8a, which act on the lower arms of the clamping jaws 5 in the clamping position of the ski binding.
  • the slide plate 8 consists of two parts, which receive the lugs 8a between them and are connected by rivets, not shown.
  • Two bearing blocks 8b and 8c are fastened on the slide plate 8, in which a bolt 9 is guided so as to be displaceable in the longitudinal direction of the ski.
  • the bolt 9 carries a collar 9a and is under the influence of a compression spring 9b, which rests with one end on the collar 9a and with the other end on the bearing block 8b. The spring 9b therefore tries to move the pin 9 towards the end of the ski.
  • the slide plate 8 there is a recess 8d, approximately T-shaped in plan view, into which the inner c and the outer tines 7d engage in the entry position of the ski binding. If the kick bar 6 is depressed by the user's foot, the outer tines 7d are supported on the two shoulders of the approximately T-shaped recess located in the central longitudinal region of the recess 8d, whereas the inner tines 7c can pivot freely in the recess 8d. These tines 7c are only for abutment on the right limit in FIG Recess 8d determined.
  • the slide plate 8 is fork-shaped.
  • Each fork tine 8e or 8f carries a roller 8g, which rests on a shoulder 10a of a one-arm locking lever 10 in the ski binding's driving position.
  • This locking lever 10 essentially extends in the longitudinal direction of the ski and can be pivoted about a bolt 10b which is fastened in projections 11a of a spring housing 11 and is guided in elongated holes 3e which are located in two plate-like projections 3f, 3g of the soleplate 3 located in the projection 3d are spared.
  • a release spring 12 which is designed as a compression spring, is accommodated and acts on a piston 13, on whose side facing away from the extension spring 12, a roller 14 is mounted.
  • This roller 14 is pressed by the release spring 12 against a one-armed lever 15 which is mounted in the shoulder 3d of the sole plate 3 on an axis 15b and which carries a cam 15a on the side opposite the roller 14.
  • This rests on a piston 16 which is guided in a bore 3k of the projection 3d.
  • the end face of the piston 16 remote from the cam 15a is in contact with the head of the mushroom-shaped follower 2.
  • the piston 16 is penetrated by a bolt 16a running in the transverse direction, which is guided in elongated holes 3m in the projection 3d and projects laterally over it.
  • axis 15b there is also an approximately U-shaped intermediate lever 19, viewed in the longitudinal direction of the ski, which is pivoted clockwise under the influence of a leg spring 19a.
  • This intermediate lever 19 rests with one arm on the bolt 16a of the piston 16.
  • Another arm of the intermediate lever 19 carries an axis 19b which on the one hand passes through an elongated hole 10c extending approximately in the longitudinal direction of the latching lever 10 and on the other hand serves as a bearing journal for a joint bracket 20.
  • the other end of the link plate 20 is articulated to a release lever 21 which is designed as a two-armed lever and can be pivoted about an axis 21a arranged in the projection 3d of the soleplate 3 or in the plate-like projections 3f, 3g thereof.
  • the mushroom-shaped follower 2 which is supported under the pressure of the piston 16 with its head against a retracted edge of the bore 3k in the approach 3d of the soleplate 3, has two approximately spherical thickenings 2a and 2b on its stem, one of which 2a in one horizontal and the other 2b is housed in a vertical guide of the bearing block 1c. This measure, in coordination with the corresponding moment arms of the soleplate, determines the ratio of the release torque required for the release in the event of a frontal fall to that of a rotary fall.
  • the set screw 18 is first turned, for example screwed deeper into the threaded bore of the bolt 1? a.
  • the lever 17 is pivoted counterclockwise and the spring housing 11 is pivoted clockwise about the axis 10b relative to the sole plate 3 by the release spring 12, the spring relaxing somewhat.
  • the roller 14, which is actuated by the release spring 12 via the piston 13 moves along the side surface of the lever 15 in the direction of the axis 15b thereof. This, however, reduces the effective lever arm of the lever 15 and additionally reduces the pressure exerted on the piston by the somewhat relaxed release spring 12.
  • the ski boot 22 (this is only indicated in FIG. 6) is attached to the step bracket 6 with the transverse surface of its heel and then depressed against the sole plate 3.
  • the jaws 5 are opened by the fact that the slide plate 8 is first shifted somewhat to the left in FIG. 1 by the control lever 7, which is coupled to the step bracket 6 via the roller 7a, against the force of the release spring 12. This is accomplished in that the outer tines 7d of the control lever 7 are supported on the two shoulders of the approximately T-shaped recess 8d and move the slide plate 8 against the ski tip.
  • the bolt 10b which forms the pivot axis for the locking lever 10, moves in the elongated holes 3e in the plate-like projections 3f and 3g of the sole plate 3.
  • the follower 2 is pivoted relative to the shoulder 3d of the soleplate 3, whereby the piston 16 in the bore 3k is pushed back against the force of the release spring 12 accommodated in the spring housing 11.
  • the piston 16 pivots the intermediate lever 19 via the pin 16a, which lifts the locking lever 10 via the axis 19b and thereby removes the latter from the rollers 8g mounted in the slide plate 8.
  • the slide plate 8 is now shifted to the left in FIG. 1 by the compression spring 9b, which is pretensioned on the collar 9a of the bolt 9 or, via this, on the nose 9e of the control lever 7.
  • the wedge-shaped projections 8a of the slide plate 8 are removed from the corresponding surfaces on the lower arms of the clamping jaws 5, and the ski boot 22 can leave the ski binding.
  • ski binding could also be equipped with a differently designed follow link or with two follow links arranged in parallel - one for frontal falls and the other for rotary falls.
