Definitions

  • the invention relates to a triggering device for a ski binding that fixes a ski boot on a ski, with an unlocking mechanism that releases the connection between the ski boot and a ski binding element and that can be controlled by the trigger signal of an electrical evaluation unit that can be loaded with an input signal.
  • a safety ski binding has already become known from AT-PS 388 110, in which the triggering takes place by means of an electromagnet via an evaluation circuit which processes the signals from the force transducers provided in the ski binding and, when certain criteria are reached, emits a trigger signal which is brief Excitation of the electromagnetic leads.
  • an electromagnetic triggerable ski binding has also become known, in which the triggering takes place by means of switching contacts which can be actuated manually or are accommodated in a mouthpiece.
  • Such a design is particularly unsuitable for racers, since the risk of undesired triggering of the ski binding due to inadvertent actuation of the manual contacts or the contacts accommodated in the mouthpiece is extremely high.
  • the object of the present invention is to avoid the disadvantages of the known triggering devices and to improve a triggering device of the type described in the introduction in such a way that the skier, in particular the racer, is enabled, regardless of the one set on the ski binding Triggers in the event of danger itself to actuate the unlocking mechanism and thus to detach the ski boot from the ski binding, ensuring that unintentional detachment, which in turn can lead to serious injuries, is prevented.
  • the invention proposes that the input signal is formed by sound picked up by a microphone.
  • the release device enables the skier to detach the connection between the ski boot and a ski binding element simply by screaming. No manual activities and no movements of the mouth or teeth are therefore required for the triggering process, for their implementation in the event of danger first considerations have to be made, as a result of which the actuation of the unlocking mechanism is considerably delayed, or even in be ⁇ certain situations can no longer be undertaken.
  • a scream on the other hand, can be uttered spontaneously in the event of danger and is even uttered frequently in the subconscious without having to think about it. It is only necessary to appropriately evaluate and amplify this cry detected by the microphone in order to actuate the unlocking mechanism.
  • the microphone can be attached to the skier's clothing, for example, similar to the way people often appear on television.
  • the microphone and preferably also the evaluation unit are arranged in a head protection for the skier, in particular a helmet.
  • This arrangement has the advantage that the microphone is located in the immediate vicinity of the skier's mouth and therefore the scream emitted is detected with certainty.
  • the microphone and preferably also the evaluation unit can be firmly connected to the helmet, that is to say integrated in particular in the helmet, so that no subsequent attachment is required and loss of the microphone or displacement thereof while skiing is avoided with certainty. It is then only necessary to establish an electrical connection between the evaluation unit and the unlocking mechanism, which can also be effected inductively, for example.
  • the electrical evaluation unit can be electrically coupled to a, preferably electromagnetically acting, actuating device for the unlocking mechanism. In particular with an electromagnetic actuator direction, the unlocking mechanism can be operated in a simple and safe manner.
  • the unlocking mechanism is released directly by the electromagnetically acting actuating device, an electromagnet with a corresponding power and therefore a correspondingly large current source are required, which must be accommodated on the ski. It is therefore expedient if only the actuation device is triggered electrically, in particular electromagnetically.
  • the arrangement is then preferably such that the actuating device has a piston which can be acted upon by a pressure medium, the pressure medium supply being controlled by the evaluation unit, that is to say electrically.
  • the force required to trigger the unlocking mechanism is applied by the pressure medium, so that the electrical power source can only be designed to control the pressure medium supply and can therefore be kept correspondingly small.
  • the pressure medium which preferably consists of compressed air, is located in a container which is accommodated on the ski and which must be correspondingly small. After an unlocking process, the available pressure medium is therefore used up and must be replaced. According to the invention, this can be done in a simple manner in that the actuating device is provided with an exchangeable cartridge containing the pressure medium, which is provided with a closure which can be destroyed when the electrical signal occurs.
  • a cartridge can be designed, for example, similarly to the cartridges used in the production of soda water in home siphon bottles, which have a small volume and are easy to replace.
  • the cartridge is displaceably arranged in a guide provided in the actuating device, which is held in its rest position by a lock and after removal of the Locking via the evaluation unit with its destructible closure by an elastic member, for example a spring, can be pressed against a mandrel, which is preferably designed as a tube. If the locking is thus released, the elastic member presses the destructible closure of the cartridge against the mandrel, so that the pressure medium in the cartridge is released and, during training of the dome acts as a tube via the channel formed by this tube, the piston, which finally causes the unlocking.
  • an elastic member for example a spring
  • the arrangement is expediently such that the binding element with the unlocking mechanism is arranged on a carrier which can be displaced in the longitudinal direction of the ski and which is movable relative to the ski by a piston which can be moved by the piston Rest is fixable. If the fixation is released, the wearer with the ski binding element arranged thereon moves and thereby releases the ski boot.
  • the catch is connected to the piston rod of the piston and is pressed into the fixing position by an elastic member, for example a spring. When the piston is pressurized, it is then displaced against the force of the elastic member and the latch is thereby unlocked.
  • Fig.l shows the block diagram of the electronic elements of the triggering device according to the invention.
  • FIG. 3 shows a longitudinal section through the unlocking mechanism together with the actuating device for it according to FIG.
  • Line III-III in Figure 4 and Figure 4 shows a cross section along the line IV-IV in Figure 3.
  • FIGS. 5, 6 and 7, in corresponding representations in FIG. 3, show the locking mechanism with the actuating direction in different operating states.
  • the triggering device has a microphone 1, which, as can be seen from FIG. 2, is fastened on a carrier 3 connected to the helmet 2 worn by the skier in such a way that it is able to pick up a cry emitted by the skier in a perfect manner. Further arranged on the helmet 2 electrical elements are included in Fig.l by the dashed line 4. These are a pre-amplifier 5, an evaluation 'unit 6, a power amplifier 7 and a current source 8.
  • the microphone 1 is coupled to the evaluation unit 6 such that in these the detected sound by the microphone 1 is converted into an electrical signal which, after amplification in the power amplifier 7, actuates an unlocking mechanism 10 provided on the ski 9, which releases the connection between the ski boot 11 and a binding part 12.
  • the binding part 12 is designed in the usual way and triggers when a predetermined force is exceeded, regardless of the response of the unlocking mechanism 10. Which he- trigger device according to the invention thus represents an additional device for the usual triggering process of a known ski binding.
  • the line 13 connected to the power amplifier 7 is electrically coupled by means of an inductive coupling element 14 to the parts “ provided on the ski 8 ” , which are identified in FIG. 1 by the dashed line 15.
  • an evaluation unit 16 which is connected to the coupling element 14 via a line 17, a power amplifier 18, a current source 19 and an electromagnetically acting actuating device 20 for the handheld device 10.
  • the electromagnetically active actuating device 20 is accommodated in a sleeve 21 which is detachably connected to a housing element 22 via a screw thread 23.
  • a guide 24 in which a Receptacle 25 is displaceably guided for a cartridge 26 containing a compressed gas.
  • the receptacle 25 is loaded by a compression spring 27, but is supported by an elastic attachment 28. which passes through an opening 29 in the sleeve 21 and has a thickened end 30 with a hole 31, into which a bolt 32 of the actuating device 20 engages, in its rest position.
  • the cartridge 26 is fixed in the receptacle 25 by an elastic plastic spacer sleeve 33, which surrounds an initially cone-shaped and then cylindrical end of the cartridge 26. At the end, the cartridge has a destructible closure 34. Cartridges of the type just described are used, for example, in home siphon bottles.
  • this actuating device 20 activates the Bolt 32 pulled out of the hole 31 of the lug 28 and thereby released the locking of this lug 28, so that the 'receptacle 25 is moved together with the cartridge 26 by the force of the compression spring 27 in the direction of arrow 35, whereby the destructible closure 34 against the tip of a dome 36 designed as a tube, which is arranged in the housing element 22, is pressed.
  • the closure 34 is destroyed and the compressed gas in the cartridge 26 flows via the mandrel 36 designed as a tube and a channel 37 into the cylinder space 38 of a pneumatic cylinder 39 in which a piston 40 is located.
  • the piston rod 41 is coupled to a sleeve-shaped catch 42, which is firmly connected to the ski 9
  • Base plate 43 connects to a base plate 43 which can be displaced in the longitudinal direction of the ski, on which base the binding part 12 and the entire unlocking mechanism 10 are fixed.
  • the Kol ⁇ ben 40 is loaded by a spring 45 such that the detent 42 effects a lock between the "base plate 43 and the support 44 in a location, in which the boot 11 is clamped in the ski binding.
  • the piston 40 is displaced against the force of the spring 45 and thus the catch 42 is brought into an unlocked position in which the locking between the base plate 43 and the slidable carrier 44 is canceled.
  • the displaceable carrier 44 and thus also the binding part 12 are displaced by a tension spring 46 in the direction of the end of the ski, and thus the connection to the ski boot 11 is released.
  • the binding part 12 together with the displaceable carrier 44 must first be displaced in the direction of the ski tip until the catch 42 engages in the bore in the base plate 43.
  • the sleeve 21 is then unscrewed, the plastic spacer sleeve 33 and the cartridge 26 are removed from the receptacle 25 and the receptacle 25 is tensioned with the aid of a tensioning element.
  • the receptacle is then moved in the direction of the actuating device 20 until the thickened end 30 of the attachment 28 again locks the receptacle 25 when the compression spring 27 is tensioned, the bolt 32 being accommodated in the hole 31 again.
  • FIG. 6 shows the release device at the moment of unlocking, that is to say when the movement of the piston 40, caused by the pressure medium supplied to the cylinder lug 38, pushes the sleeve-shaped catch 42 into a position in which the carrier 44 is also fixed the base plate 43 is released.
