Definitions
- the invention relates to a release ski binding according to the first part of claim 1.
- Such a trigger ski binding is described in FR-A1-2 228 510 or in the additional application DE-A1-24 01 729 which justifies the priority of this application to DE-A1-23 24 078.
- the trigger mechanism is accommodated in a space which is located between the base plate and the sole plate.
- this requires special sealing measures against the ingress of snow and dirt.
- the structure of this binding is complicated, and consequently its assembly is complicated and time-consuming.
- the release ski binding according to DE-A1-23 24 078 is a functional separation of the release and holding system.
- the holding system should be able to be actuated safely by the minimal control movements of the control device according to the master patent.
- the additional avoidance only includes the design of the restraint system, so that there is no complete ski binding; this forms a complete unit only in cooperation with the release system according to the parent patent. This unit also has the disadvantages mentioned at the outset in connection with DE-A1-23 24 078.
- 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 structure and in which the ski boot is reliably held while driving, but immediately in the event of a fall is released. Furthermore, there should be no sealing problems between the base plate and the sole plate.
- the holding mechanism in addition to the two jaws acting on the tip of the shoe also has a heel holder which can be pivoted about a second transverse axis, the transverse axis of which can be displaced in the longitudinal direction of the ski and is under the influence of a compression spring which tends to push it towards the tip of the ski ski boot placed between the jaws.
- the pressure spring acting on the two clamping jaws via a pull rod controls the mounting or release of the ski boot in the front and rear area by one and the same spring, with the heel holder in the driving position by means of a spring-loaded locking element that can be released by the pull rod against the sole plate is locked.
- clamping wedges which are displaceably mounted on the soleplate and are under the influence of springs, in particular one compression spring each. In this way, strong pressure or upper arms of the jaws can be brought to bear on the ski boot with relatively low spring forces.
- the invention provides that the two clamping wedges are connected by a cross bar, with upward projecting bolts being provided on each clamping wedge, each of which engage in an elongated hole in the cross bar. This measure helps to ensure that the two wedges are loosened evenly.
- the crossbar is articulated to the drawbar via a bolt which engages in an elongated hole in the drawbar.
- the transverse axis for the heel holder is mounted on a piston which is guided in a bore in the sole plate or in an extension thereof extending in the longitudinal direction of the sole plate, and a second piston can also be displaced in this bore stored, which is connected via the cross bolt to the fork-shaped end of the pull rod, the compression spring being arranged between the two pistons.
- the compression spring is used not only for pressing the heel holder onto the ski boot while driving, but at the same time for releasing the two clamping jaws. B. in the event of a fall.
- the following feature also aims in this direction: the second piston carries a piston rod which projects out of the bore and which an actuator of the holding device is assigned.
- the or each latching element has a hook which is articulated on the heel holder and is under the influence of a leg spring and in the driving position of the ski binding of the or each latching member has a projection of the sole plate with its hook reaches under.
- a stop which causes the or each locking element to be released is assigned to the or each locking element on the pull rod. This stop enables the heel holder to be released before the two jaws have opened, so that first the heel and then the cap of the ski boot are released.
- the heel holder is under the influence of a helical spring which is supported on the one hand on a (third) transverse axis mounted in the soleplate and on the other hand on a (fourth) transverse axis in the heel holder.
- This type of mounting of the positioning spring makes it possible for the heel holder to always be under the pressure of the positioning spring, regardless of whether it is in the position due to the compression spring, advanced towards the tip of the ski (entry position) or in the position due to the depression of the Ski shoe conditionally retracted position (driving position) is located.
- the invention provides that the heel holder is guided in a guide slot of the extension which also extends vertically.
- the axis for the heel holder is largely protected since, regardless of whether the ski boot is inserted parallel to the vertical longitudinal center plane or inclined in the ski binding, only a normal force is exerted on the axis.
- bending of the heel holder is prevented even when the ski binding is subjected to rough stress.
- Fig. 1 is a side view of the ski binding in the driving position, partly in section along the line I-I in Fig. 2 and Fig. 2 is a partially sectioned plan view of the ski binding.
- 3 and 4 show a detail of the ski binding in longitudinal section or in section along the line IV-IV in FIG. 3 with the ski binding deflected laterally.
- Three holding elements are attached to a ski 1, namely a first transverse axis 1a, a substantially vertical vertical axis 1 and a bearing block 1c.
- a sole plate 2 above the ski. This can be pivoted in the vertical direction about the first transverse axis 1a and rotated about the vertical axis 1b in a plane parallel to the top of the ski.
- two clamping jaws 3 are pivotably mounted on axes 3a extending in the longitudinal direction of the ski.
- the jaws 3 are designed as two-armed levers and are under the influence of weak leg springs, not shown, which endeavor to press the jaws onto the ski boot.
- the region of the sole plate 2 facing the end of the ski carries a shoulder 2a, to which a holding device 4 is fastened and in which a bore 2b is cut out.
- Two pistons 5 and 6 are slidably mounted in the bore 2b.
- a compression spring 7 is arranged between the two pistons 5, 6.
- the piston 5 facing the ski tip carries a bearing block 5a in which a fork-shaped heel holder 8 is pivotally mounted on a second transverse axis 8b, which is under the influence of a helical spring 8a and in a vertically extending guide slot 2e in the neck 2a is led.
- the raising spring 8a is held at one end on a (third) transverse axis 2f mounted in the sole plate 2 and at the other end on a (fourth) transverse axis 8c in the heel holder 8.
- the heel holder 8 engages in the driving position with the ends of the fork tines in recesses in the heel of the ski boot.
- the heel holder 8, together with the two clamping jaws 3 reliably holds the ski boot to the ski 1 during the journey.
- at least one locking member 9 is articulated on the heel holder 8, which has a hook, is under the action of a leg spring 9a and engages under the projection 2c of the sole plate 2 with its hook in the driving position.
- the sole plate 2 has two approximately trapezoidal recesses 2d, in which clamping wedges 10 are mounted.
- the clamping wedges 10 are under the influence of compression springs 10a.
- the clamping wedges 10 carry bolts 10b, which each engage in an elongated hole 11 in a crossbar 11.
- the crossbar 11 carries a further bolt 11b which engages in the elongated hole 12a of a pull rod 12.
- This pull rod 12 extends to the neck 2a of the sole plate 2 and is forked at its end remote from the jaws 3.
- the ends of the two fork tines are articulated on the piston 6 by means of a bolt 13.
- the pin 13 is guided on both sides of the piston 6 in guide slots of the approach 2a.
- the pull rod 12 carries at least one stop 12b, which is intended to release the locking member 9.
- a piston rod 6a is attached to the piston 6 and can be designed, for example, as a bearing for a roller 14, which serves as a bearing for an actuating member 15 of the holding device 4.
- the actuating member 15 is designed as an angle lever which is loaded by a leg spring 16 and can be pivoted about an axis 15a, one arm of which rests on the roller 14 and is held in this position by a stop 15b.
- the other, fork-shaped The arm of the angle lever 15 rests on a bolt 17 which passes through elongated holes 4a in the holding device 4 and a piston 19 acted upon by a compression spring 18, which is guided in a longitudinal bore 4b of the holding device 4.
- the bias of the compression spring 18 can be adjusted by an adjusting screw 20.
- a follower 21 is also pivotally mounted with a head 21a, which is approximately mushroom-shaped and whose stem 21b, which has two spherical thickened portions 21 and 21d, has an outwardly diverging conical bore in the bottom of the one designed as a blind bore Bore 4b penetrated in the holding device 4.
- the bearing block 1c attached to the ski 1 for the follower 21 has two guideways, namely a horizontal 22a and a vertical 22b, one of which 22a is assigned to the thickening 21c and the other 22b to the thickening 21d.
- the heel holder 8 In the entry position of the ski binding, the heel holder 8 is in the raised position under the influence of the spring 8a.
- the piston 5 is displaced under the influence of the compression spring 7 against the ski tip in the bore 2b.
- the clamping jaws 3 are held in a vertical position by the wedges 10 via the compression springs 10a.
- the heel holder 8 is pivoted counter-clockwise and at the same time with its articulation axis slightly shifted towards the end of the ski. Heel holder 8 and shoe sole form a kind of knee joint when stepping on.
- the compression spring 7 By moving the articulation axis 8b of the heel holder 8, the compression spring 7 is tensioned. This compression spring 7 therefore pushes the ski boot between the jaws 3 over the heel holder 8.
- the heel holder 8 In the lower end position, the heel holder 8 is locked against the sole plate 2 by the locking member 9. The ski boot is thus in the position intended for the ride.
- the follower 21 is also pivoted, which results in a movement of the piston 19 in the direction of the ski end. If the so-called elastic range of the ski binding is exceeded in the horizontal or vertical direction, the angle lever 15 is pivoted clockwise so much by the piston 19 that its end facing the roller 14 moves away from the roller. As a result, the compression spring 7 accommodated in the bore 2b can relax. This has the consequence that the clamping wedges 10 are withdrawn from the pull rod 12 and that the heel holder 8 is also relieved of the pressure of the compression spring 7, which tries to move it against the ski boot. Due to the movement of the pull rod 12, the locking member 9 was also removed from the projection 2c of the soleplate 2 by the stop 12b. The heel holder 8 can therefore pivot upwards under the influence of the spreading spring 8a and release the ski boot.
- the ski binding is triggered arbitrarily by means of a release lever mounted in the holding device 4, but not shown in the drawing, by means of which the angle lever 15 is removed from the roller 14 against the force of the leg spring 16.
- the rest of the process corresponds to that of the involuntary release of the ski binding.
- the pull rod 12 with the piston 6 returns under the influence of the compression springs 10a acting on the tensioning wedges 10 to the position shown in FIG. 2, in which the angle lever 15 under the influence of the leg spring 16 engages the Roll 14 creates.
- the heel holder8 is still in the raised position in which the ski boot has left the binding. The ski binding is therefore ready to be re-entered with the ski boot.
