Definitions

  • the invention relates to safety ski bindings with an electronic circuit according to the features of the preamble of claim 1.
  • the version according to ... 535 works with shear pins that support the sole holder.
  • the sole holder is released and in turn releases the ski boot from its binding on the ski. A then necessary replacement of the shear pins and reattaching the sole holder on the slopes is a skier unreasonable.
  • the version according to ... 756 provides for an error control system in the electronic logic which, if the electronics fail, switches over to a purely mechanical release function of the safety ski binding. As a result, the electronic circuit must be expanded at least by an additional circuit in order to detect and report errors.
  • a safety mechanism is also provided in the safety ski binding according to ... 841, which switches the release system to a purely mechanical, pneumatic or hydraulic emergency release system in the event of an electrical control failure.
  • the others have the advantage that they work in the event of a defect in the circuit or the magnet or in the event of a power failure as usual safety ski bindings, but they are designed so that an error message a switching mechanism is necessary.
  • the invention is based on the object.
  • the device provided according to the invention makes a switching mechanism unnecessary, since the separating element of the device comes into operation with a sufficient delay, however, which is permissible in relation to the risk of injury to the skier.
  • An expedient embodiment of the invention comprises the features of claim 2.
  • the process of releasing according to the invention is effected by sufficient movement of the cylinder.
  • the openings in pistons preferably comprise a throttle and a check valve for the first cylinder chamber.
  • an instantaneous reset of the cylinder is achieved in a known manner.
  • the cylinder-fixed cavity can taper towards its free end and form the separating member.
  • the device can be arranged so that the isolating element can directly influence the armature of the electromagnet.
  • the single figure of the drawing shows schematically and partly in section the device according to the invention in association with a locking device of a sole holder.
  • the safety ski binding which can be designed to hold a ski boot in any known manner, is only shown to the extent required by the parts essential to the invention. It has an electronic circuit that detects at least the forces and / or moments acting on the skier's leg via corresponding measuring paths by at least one transducer and, when a predetermined threshold value is reached, excites or de-energizes an electromagnet 1, a so-called remanence magnet, the armature 2 of which lock of a sole holder shown by an angle lever 3 releases.
  • the axis 4 of the angle lever and the holding plate 5 of the electromagnet are parts of the binding that are held in a ski-tight state in use.
  • the armature 2 of the electromagnet is designed as a hinged armature and is under the influence of a helical tension spring 6 which loads it in the opening direction in the present case is formed by a peg-shaped extension of the soft iron core of the electromagnet 1. It also serves as a guide for the hinged anchor 2.
  • a current impulse passes through the coil of the electromagnet due to a pulse generated in the electronic circuit, which cancels the magnetic holding force for the anchor at least to the extent that the anchor hit under the influence of the coil spring 6 against the angle lever 3 and it can pivot against the force of its retaining spring about the axis 4, which leads, in a manner not shown, directly or indirectly to releasing the locking of the sole holder, so that the ski boot is off can loosen the binding and thus the ski.
  • a force or a moment acts on the skier's leg that corresponds to the respectively predefined threshold value
  • a device designated 8 in its entirety is provided, which is influenced on the one hand by the sole holder, not shown, or a part that is operatively connected to it, at least via the measuring path.
  • the device has a separating element 9, which in the present case can influence the angle lever 3 in the sense of releasing the locking of the sole holder.
  • a holding plate 10 is provided for the device 8.
  • This device comprises a shock absorber with a piston 11 which is fixedly connected to the holding plate 10 via its piston rod 12.
  • a cylinder 13 is slidably mounted on the piston and the piston rod. Its interior is divided by the piston into a first (14) and a second cylinder chamber 15 for a liquid or gaseous medium. Both chambers are connected to each other by a throttle 16 and a check valve 17 in the piston 11.
  • the piston 11 and its piston rod 12 are drilled axially and receive a plunger 18 which is connected directly or indirectly to the sole holder in any suitable manner, not shown, with respect to the illustration to the right of the holding plate 10.
  • a spring plate 19 in the cylinder chamber 15. This is attached to a stepped part 20 of the tappet, which extends through the cylinder end wall 21 into a cylinder-fixed cavity 22 and carries a flange 23 at the free end, the edge of which carries the Cylinder end wall 21 engages behind.
  • a damping spring 24 is supported on the cylinder end wall and acts on the spring plate 19 of the plunger 18.
  • the cylinder-fixed cavity 22 is formed by the interior of the separating member 9, which tapers towards its free end. While the separator in the present example is intended to interact with the angle lever 3, it can just as well interact with a suitable other part, for example directly with the hinged anchor 2, in the sense of releasing the locking of the sole holder.
  • the device according to the invention is always ready for operation. It therefore does not form an "emergency release system" that is only activated by manual or automatic switchover if there is a power failure or a defect in the circuit or in the magnet occurs.
