Definitions

  • the invention relates to a safety ski binding with electronic evaluation and release circuits, which process the signals originating from force transducers and, in the event of danger, activate a release device for releasing the boot held in the binding, and which can be supplied by a voltage source via a switching device.
  • Such a safety ski binding is e.g. made known by DE-A No. 2705174.
  • the switching device is actuated when entering the binding and closes the supply circuit for the electrical supply of the control circuit, which controls the triggering of the binding in the event of danger. This ensures that the control circuit is only live when a shoe is actually held by the binding. In this way it is prevented that the control circuit is constantly under voltage and the current source, usually a battery, is constantly, although slightly, loaded due to the inevitable leakage currents.
  • the aim of the invention is to propose a safety ski binding in which the power consumption is reduced to a minimum.
  • the switching device has an activatable acceleration sensor, which is connected to an electronic switching element via a timing element and possibly a threshold switch. This ensures that the evaluation and release circuit of the binding are only supplied with voltage when acceleration forces act on the ski or the binding, which indicate that the skis are actually being driven and are therefore dangerous and require the binding to be released Situations.
  • the power supply to the trip and evaluation circuit remains interrupted.
  • the accelerometer in a manner known per se (DE-A No. 2139557) by a free end a one-sided clamped contact spring and a surrounding contact contact is formed, and that the contact piece and the counter-contact are displaceable in the axial direction between two positions, in one of these positions the counter-contact is outside the range of movement of the contact piece and one of the contacts on one ski-fixed and the other is held or connected to a part of a conventional thrust compensation device that is displaceable relative to this.
  • This also has the advantage of a simple design of the accelerometer.
  • an acceleration sensor is characterized in that the acceleration sensor is formed in a manner known per se (see DE-A No. 2139557) by a contact piece fastened to the free end of a bar spring clamped on one side and a mating contact surrounding it that an insulator which can be inserted into the annular gap between the contact piece and the mating contact is provided, the contacts preferably being held on a part fixed to the ski, whereas the insulator is held on a part of a conventional thrust compensation device which is displaceable relative to the latter.
  • the acceleration sensor is formed in a manner known per se (see DE-A No. 2139557) by a contact piece fastened to the free end of a bar spring clamped on one side and a mating contact surrounding it, and that between one of the contacts and the power source is connected with a switch closed only when the shoe is fixed in the binding.
  • This arrangement also ensures that the power supply to the release and evaluation circuit is interrupted when the skis are being transported.
  • the timing element is formed by a series-connected RC element, the acceleration sensor designed as a switch being connected in parallel with the capacitor and the electronic switching element at a voltage below the voltage at the capacitor switches through.
  • the switching of the electronic switching element occurs practically without delay when a sufficiently large acceleration pulse leading to the closure of the contacts of the accelerometer occurs, it is also possible to set the switching threshold for the accelerometer and thus the switch-on threshold for the evaluation and the trip circuit relatively high, so that these circles are only activated when acceleration forces occur, as they occur in situations that come close to the triggering conditions of the binding, but still clearly, with regard to the intensity of the impulses, among them lie.
  • the duty cycle of the evaluation and the tripping circuit or the time that these circuits are ready for operation can be reduced to a minimum, and the service life of the battery provided for the voltage supply can thereby be extended.
  • the acceleration sensor 1 is connected to a timing element 2, which is activated when a corresponding acceleration occurs.
  • the response threshold can already be determined by the structure of the accelerometer 1, e.g. if this is designed as an acceleration switch 10, or else a threshold switch, e.g. a Schmitt trigger.
  • the timing element remains in the active state for a predetermined time after each excitation, in that it controls the downstream electronic switch 3 in the sense of switching through.
  • the electronic unit 4 is connected to the voltage source 5 during this period and is thus ready for operation.
  • the electronic unit 4 comprises both an evaluation circuit (not shown) of processing force transducers as well as a control circuit controlled by this, which triggers the binding in the event of danger and releases the shoe from the binding.
  • the evaluation circuit of the electronic unit could, for example, be designed according to an older, not yet published proposal and the triggering circuit could be designed by a solenoid valve according to this patent application.
  • the acceleration sensor 1, the timing element 2 and the electronic switch 3 ensure that the electronic unit 4 is connected to the voltage source 5 only during a period in which the ski provided with such a binding is in motion.
  • the acceleration sensor is designed as an acceleration switch 10, which closes when a certain acceleration value is reached and which is connected in parallel with the capacitor 11 of the RC element, which is made up of the resistor 12 and the capacitor 11 and serves as a timing element 2. If the acceleration switch 10 closes, the voltage at the capacitor 11 breaks down and the Schmitt trigger 13 connected at the connection point of the resistor 12 and the capacitor 11 changes its switching state. As a result, the voltage level at the output of the downstream inverter 14 jumps to a sufficiently high value and the electronic switch 3, which is designed as a transistor, switches through, so that the electronic unit 4 is supplied with current.
  • the capacitor 11 charges via the resistor 12. If the voltage across the capacitor 11 reaches a certain value, the switching state of the Schmitt trigger 13 changes and this returns to its initial state, as a result of which the output voltage of the inverter suddenly drops to zero and the electronic switch 3 opens.
  • the Schmitt trigger 13 and possibly also the inverter 14 could be dispensed with, but compliance with a switching threshold would then only be possible within a relatively large fluctuation range.
  • 3 to 5 show schematic embodiments of acceleration switch arrangements, in which it is ensured that a response of the acceleration switch 10 during the mere transport of the binding or skis, that is to say without a shoe held by the binding, has no effects, or no switching through of the electronic switch 3 has the consequence.
  • the acceleration switch 10 consists essentially of a connector 20 made of conductive material, on which a e.g. to the battery 5 or to the connection point of the resistor 12 connected to the capacitor 11 leading electrical line and in which a bar spring 21, e.g. a piece of spring wire is anchored, which carries a contact piece 22 at its free end.
  • This contact piece 22 serves as a pendulum of the acceleration switch.
  • the acceleration switch 10 has an insulating tube 23 fastened to the connection piece 20, in which an opposite contact 24 surrounding the contact piece 22 with play is held, to which an electrical line is connected.
  • the mating contact 24 is held in the insulating tube 23 so as to be displaceable in the axial direction. 6 and 7, this mating contact 24 is connected to an attachment 41 connected to the jaw 40 having a thrust compensation device via an insulator.
  • the remaining part of the acceleration switch 10 is attached to a ski-fixed holding part 42. It is thereby achieved that there can only be contact between the contact piece 22 and the mating contact 24 if the extension 41 of the jaw 40 has approached the ski-fixed holding part 42 sufficiently far. However, this is only the case with a shoe 43 held in the binding, so that simply transporting the skis provided with such a binding does not result in contact in the acceleration switch 10 and thus no switching of the electronic switch 3 can occur.
  • the mating contact 24 ' is fixed in the insulating tube 23 and is always located in the range of movement of the contact piece 22.
  • an insulator 25 with a circumferential, axially projecting edge or at least three axially projecting projections is provided . This insulator 25 is held axially displaceably against the mating contact 24 ', the peripheral edge being insertable into the annular gap between the contact piece 22 and mating contact 24' and being removable therefrom.
  • the insulator 25 is expediently fastened to a part connected to the jaw 40 or moving with it, whereas the insulating tube 23 of the acceleration switch is fastened to a ski-fixed holding part.
  • the attachment must be such that the distance between these parts increases when entering the binding.
  • the connecting piece 20 and the mating contact are likewise arranged rigidly in the insulating tube 23, but a switch 26 is provided in the connecting line to one of these two parts, which switch is actuated when entering the binding, or it closes as soon as the shoe is anchored in the binding or as soon as the shoe has approached its position anchored in the binding sufficiently.
  • This arrangement also ensures that e.g. Acceleration forces occurring during the transport of the skis do not lead to the electronic switch 3 being switched on.
