Definitions
- the invention relates to a release ski binding according to the first part of claim 1.
- Such release ski bindings are described in DE-C-2533337.
- 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 creating a release ski binding of the type mentioned, which is simple in construction and enables precise setting of the desired release moments in the event of a frontal fall and a turning fall.
- the clamping jaws essentially forming the holding mechanism being able to be brought into the holding position in a controlled manner by the slide plate, and the slide plate being actuable by means of the control lever and the step bracket, the slide plate being controlled by the intermediate lever which is operated by means of the Detent lever releasably connects the slide plate with the resilient holding device, all goals are solved individually and also in common.
- the design according to the invention also gives the designer great freedom for the design of the individual components.
- kick bars for ski bindings (cf. US-A-4312517).
- 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 boot is being inserted, and at the same time to align the ski boot both in the longitudinal direction and in the transverse direction of the ski.
- the holding elements for the ski boot are not actuated by the kickbar.
- the function to be performed by the control lever is divided into two pairs of elements, the one pair only displacing the slide plate towards the end of the ski, the other pair, however, initially adjusting the slide plate towards the tip of the ski and then an abrupt one Move the slide plate to the clamping position.
- the measure of claim 4 simplifies the entry of the ski boot into the ski binding insofar as the relative movement between the tip of the ski boot and the ski is significantly reduced compared to the reverse arrangement (arrangement of the kick bar axis at the end of the slide plate facing the end of the ski).
- the features of claims 5 and 6 are provided according to the invention.
- FIG. 1 is a section along the line II 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 111-111 in Fig. 5
- Fig. 4 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 8 is a detail of the ski binding in longitudinal section or in section along the line VIII-VIII in Fig. 7 shown 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, furthermore a receiving bore 3c for the bearing journal 1b and a shoulder 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 set-up spring 6b designed as a leg spring.
- the kick bar 6 has on its underside a guide 6c which extends in its longitudinal direction and in which a roller 7a is guided which is mounted at 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. 6, 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, 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 abuts the collar 9a at one end and the bearing block 8b at the other end. The spring 9b therefore tries to move the pin 9 towards the end of the ski.
- the slide plate 8 there is an approximately T-shaped recess 8d in plan view, into which the inner 7c and the outer tines 7d engage in the entry position of the ski binding. If the kick bar 6 is depressed by the foot of the user, 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 intended to rest against the right-hand boundary of the recess 8d in FIG. 8.
- 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 extends essentially in the longitudinal direction of the ski and is pivotable about a bolt 10b, which is fastened in lugs 11a of a spring housing 11 and is guided in elongated holes 3e which are recessed in two plate-like projections 3f, 3g of the soleplate 3 located in the lug 3d are.
- 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 release 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 soleplate 3 on an axis 15b and carries a cam 15a on the side opposite the roller 14.
- This bears against 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 On axis 15b is also a - in ski length seen direction - about U-shaped intermediate lever 19 mounted, 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 running approximately in the longitudinal direction of the latching lever 10 and, on the other hand, serves as a bearing pin for a joint plate 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 21 a arranged in the projection 3d of the sole plate 3 or in the plate-like projections 3f, 3g thereof.
- the mushroom-shaped follower 2 which is supported by the pressure of the piston 16 with its head on a retracted edge of the bore 3k in the approach 3d of the sole plate 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 adjusting screw 18 is first turned, e.g. screwed deeper into the threaded bore of the bolt 17a.
- the lever 17 is pivoted counterclockwise and the spring housing 11 is pivoted clockwise about the axis 10b relative to the soleplate 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 clamping jaws 5 are opened in 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 by the outer prongs 7d of the control lever 7 being supported on the two shoulders of the approximately T-shaped recess 8d and displacing the slide plate 8 against the ski tip.
- the bolt 10b which forms the pivot axis for the latching mechanism 10, moves in the elongated holes 3e in the plate-like projections 3f and 3g of the soleplate 3.
- the follower 2 is pivoted relative to the shoulder 3d of the soleplate 3, whereby the piston 16 in the bore 3k against the force of the release spring 12 housed in the spring housing 11 is pushed back.
- 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 with a differently shaped mushroom-shaped follower or with two parallel links - one for frontal falls, the other for rotary falls.
