Definitions

  • the invention relates to a locking device for an electronic safety ski binding with two interlocked parts, of which the locked part is connected to a sole holder and movable between its holding position, in which it is held by the other locking part movable by a rotating magnet, and its release position is, wherein the locking part consists of an angle lever, the first arm is provided with a hook-shaped projection holding the locked part in the holding position and on the second arm the movement of the rotary magnet is transmitted and thereby the hook-shaped projection is brought out of engagement with the locked part .
  • Electronic safety ski bindings known from DE-OS 2244949 and 2519544 consist of force transducers emitting electrical signals for detecting the forces and / or torques acting on the skier's leg and an electronic circuit that actuates the triggering device when dangerous forces or torques occur.
  • the mechanical release device has a lock that is released by the force of an electromagnet that is switched on by the release signal.
  • Rod-shaped or U-shaped electromagnets are used, the force exerted on the movable armature depends, among other things, on the length of the air gap and which cannot prevent the lock from being released by vibrations or other external influences.
  • an electric motor is provided as a rotating magnet, on the armature shaft of which one end of a cable is attached, the other end of which is connected to the second arm of the angle lever is that after switching on the electric motor, the cable wound on the armature shaft pivots the angle lever and thereby brings its hook-shaped projection out of the locked engagement with the locked part.
  • the angle lever In addition to the fact that the cable provided for pivoting the angle lever and wound onto the armature shaft forms a fault-prone actuating device, the angle lever must be held in its latched position by a relatively strong spring in order to avoid false tripping as a result of vibrations. In the event of a trigger, the cable must also overcome the force of the retaining spring, which requires the use of a stronger motor and is disadvantageous because of the higher electrical energy requirement associated therewith.
  • the object of the invention is therefore to provide a locking device of the type specified at the outset, which guarantees a vibration-proof locking of the parts locked together even without a retaining spring securing the locking.
  • this object is achieved in that the rotary magnet for interacting with the second arm of the angle lever carries a disc with a cam on its axis of rotation and in that the cam has a face which is concentric with the disc and which in the locked state against a projection in the locked state abuts, which is located on the opposite side of the hook-shaped projection of the first arm and runs off from it when the rotary magnet has rotated the disk so far that the contact surface just touches the second arm.
  • the locked part is held securely in its locked position without a retaining spring securing the latching in that the cam holds the first arm in its locked position with the locked part and only releases it when it counteracts the pivoting of the two-armed lever the projection arranged on its second arm runs up.
  • a counterweight which balances its weight and moment of inertia is expediently arranged on the side of the disk opposite the cam.
  • the slider 1 forms a locked part, which is connected in a manner not shown to the sole holder of an electronic safety ski binding and is locked in its illustrated holding position with the locking part consisting of a two-armed lever 3.
  • the slide 1 is acted upon in the direction of arrow A by the force of a spring (not shown) and is held in a longitudinally displaceable guide of the housing 4.
  • the slide 1 has at its outer free end a locking lug 2, behind which the locking lug 5 of the first arm 6 of the two-armed lever 3 engages in the holding position shown. In the locking position shown, the slide 1 and the first arm 6 are approximately parallel to one another.
  • the two-armed lever 3 is pivotally mounted in the housing about the bolt 7 fixed to the housing.
  • the second arm 8 of the two-armed lever 3 is at right angles to the first arm 6.
  • the second arm 8 has at its free outer end a projection 9, which with an inclined contact surface 10 is provided.
  • a cam disk 11 On the shaft of the rotary magnet, not shown, which runs parallel to the bolt 7, a cam disk 11 is firmly placed, which lies in the plane of the two-armed lever 3.
  • a cam 12 is placed on the circumference of the circular disk-shaped part of the cam disk 11 and extends approximately over a quarter of the circumference of the circular disk-shaped part of the cam disk 11.
  • the cam 12 has at its front end in the direction of rotation B a curved run-up surface which runs up against the inclined run-up surface 10 of the projection 9 by rotating the cam disk 11.
  • the cam 12 Following the curved contact surface 13, the cam 12 has an outer end face which is curved concentrically around the shaft of the rotary magnet.
  • the cam has a step 14 at its rear end, via which it drops approximately perpendicularly to the edge of the approximately circular disk-shaped part of the cam disk 11.
  • the first arm 6 of the two-armed lever 3 has a projection 15 on its free side opposite the nose 5, which is supported in the illustrated locking position on the circumferential surface of the cam 12 which is curved in the shape of a circular arc.
  • the locking of the first arm 6 with the slide 1 is released in that the rotary magnet rotates the cam disc in the direction of arrow B until the curved contact surface of the cam 12 abuts against the inclined surface of the projection 9 and the two-armed lever 3 in the direction of the further rotation Arrow C pivoted.
  • the step 14 of the cam 12 rotates over the rear edge of the projection 15, so that the blocking of the first arm 6 is released and by pivoting the two-armed lever 3 the lugs 2, 5 disengaged.
  • a counterweight 16 is attached to the opposite side of the cam disk 11.
  • Springs (not shown) can be provided to reset the two-armed lever 3 and the rotary magnet after the lock has been released.
