Definitions
- the invention relates to a release mechanism for a safety ski binding with at least one sole holder, holding jaws or the like, which is arranged in a housing which can be fixed on the top of a ski and engages a two-part slider which can be displaced against the force of a spring, the one slider part being the displaceable Abutment for the spring carries and the other abutment of the spring, at least in the downhill position, is supported on a ski-fixed binding part, the like of the sole holder, holding jaws or the like.
- the flow of force applied to the spring by means of the two-part slide is secured by a lock, which lock can be released directly mechanically or indirectly through the interposition of an electronic circuit when a predetermined limit value is exceeded, which circuit responds to signals triggered by a sensor system and triggers this circuit earlier in time than the purely mechanical release.
- a trigger mechanism of the type mentioned is known for example from EP-OS 33 131. This discloses a binding which releases both mechanically and electronically, in which, in the event of failure of the electronic control, the binding is triggered by the built-in mechanism, albeit at a somewhat increased value.
- the spring is arranged between the two slide parts, one abutment of this spring being locked in the downward position, but when a predetermined limit value is exceeded, it can be moved by releasing the lock (see FIGS. 5 and 6).
- the two slide parts thus act in opposition to one another, and furthermore that support surface on which the abutment is in the downward position is supported in a stationary manner, however, when the binding is released, is also displaceable in the longitudinal direction of the ski, so that there is an increased overall length.
- a sensor system which forwards signals to a circuit which actuates a trigger mechanism.
- the sensor is preferably a piezo element, which acts on the crystal structure of the elements at a certain pressure, i.e. generate a certain voltage with practically no measurable change in path, which is then used as an electrical signal.
- the EP-OS further discloses that light barriers or the like instead of the pressure sensors. can be used. Light barriers are stationary light-optical systems with a light-transmitting part and a light-receiving part, a light beam emitting from the light-transmitting part in the direction of the receiving part. Signal acquisition from a light barrier follows either by interrupting the light beam by means of an object or in an inverse manner by canceling such an interruption.
- AT-PS 368.025 describes a release mechanism which interacts with sole holder levers of a toe piece which can be swung out laterally. After a certain pivoting movement of one of the two sole holder levers, the coupling device is released, so that an almost force-free pivoting out of the sole holder lever is ensured by the then no longer spring-loaded slide.
- This trigger mechanism works purely mechanically.
- a triggering device controlled by an electronic circuit has the binding described in DE-OS 29 07 939. With this binding, the values recorded by force sensors are further processed in an electronic circuit. Recognizes the electronic circuit, in that the forces exerted on the skier have reached a critical value, an electromagnetic device is put into action, while driving a pinion in such a way - that a toothed rack, a toggle linkage buckles (s.insb.Fig.1-3 ). This frees a nose from a pivot and also releases the hooks holding the ski boot to the side. In this way, a housing is released for rotation, so that the ski boot can rotate with the housing and can also be released from the housing by releasing the hooks as a result. If the electronic circuit fails or the battery is discharged, however, no triggering is possible with this binding. Furthermore, a relatively high electrical power is required to actuate the trigger mechanism.
- the invention has now set itself the task of creating a trigger mechanism of the type described in the introduction compared to a shorter overall length, furthermore to make the sensor system respond to an analog signal.
- the lock as is known per se, is provided between the two slide parts and can be released as a function of the slide stroke, in that the other abutment of the spring, as is also known, remains firmly supported in every position of the binding, that the sensor system is formed by a potentiometric displacement sensor, which responds to the slide stroke, and that the signals can be processed in the electronic circuit as a function of a time duration.
- the two slide parts can be arranged one behind the other and based on the release spring be arranged concentrically to this, so that there is a shorter overall length, which measure is further favored by the fact that the lock is provided between the two slide parts.
- these features are listed as known per se.
- the circuit responds to signals which originate from a potentiometric displacement sensor which in turn responds to the slide stroke.
- This potentiometric displacement sensor delivers an analog signal corresponding to a variable distance, which can be processed in the electronic circuit as a function of a time duration. It was also in no way obvious to conclude from the EP-OS such a potentiometric displacement sensor, since, as stated above, the disclosed sensor systems have a different technical solution or technical effect than that of the sensor system according to the invention.
- a further feature of the invention is that the binding part which releases the coupling device between the slide parts is a release sleeve with a toothed rack which has a toothing in which a pinion driven by the motor engages, which release sleeve, as is known per se, has an inner inclined one Has conical surface on which the ball forming the lock or the like. prevent the flow of force between the spring and the two slide parts.
- Fig. The trigger mechanism of a safety ski binding in side view in section in the downhill position
- Fig.la an electronic circuit in the block diagram
- Fig. 2 the trigger mechanism schematically in plan view
- Fig. 3 the trigger mechanism at the time of release in side view in section
- Fig. 4 schematically shows the trigger mechanism at the trigger point in plan view.
- the trigger mechanism according to the invention is housed in a housing 1.
- the housing 1 can now represent a ski-fixed component or a component mounted in a further binding part.
- a two-part slider is mounted within the housing 1, one slider part 2 of which is designed as a pull rod, the one or whose end region is provided with a threaded section 2 a which carries a bearing 3 for a spring 4.
- the other end of the spring 4 is supported on an intermediate wall 5 of the housing 1.
- the end region of this slide part 2, which has the threaded section 2a, is further provided with a screw head 6 which projects outwards from the housing 1 and is provided with a slot for receiving an actuating tool, for example a screwdriver.
- the bias of the spring 4 can therefore be adjusted by turning the screw head 6 of the slide part 2 in a manner known per se.
- a central section 2b adjoins the threaded section 2a of the pull rod 2, which section merges via a shoulder 7 into a section 2c, the diameter of which is larger than the diameter of the central section 2b.
- the pull rod 2 is at least partially surrounded in the area of its middle section 2b and in the area of its section 2c by a cage 8 which also passes through the intermediate wall 5 of the housing 1, this end area of the cage 8 carrying a thread of the second part, onto which / slide - / 9 is screwed on.
- the part of the slide / 9 represents that component of the binding, which can be acted upon, for example, by the sole holder levers of a front jaw which can be swung out in a horizontal plane, bar 9.
- the / also a component of a binding with a sole plate component / which / cooperates / with holding jaws acting on the shoe sole or on a sole fitting. and Such training are known per se / do not form the subject of the present invention.
- the end region of the cage 8 assigned to the middle section 2b of the pull rod 2 is penetrated by bores for receiving balls 10.
- the bores are evenly distributed on the circumference of the cage 8, forming a circular ring, bores being provided for at least three balls 10.
- the diameter of each ball 10 is selected so that it sits in its associated bore with little play. In the downward position of the safety ski binding, the balls 10 are supported on the shoulder 7 which separates the middle section 2b from the section 2c.
- the cage 8 is acted upon by a compression spring 11, which partially surrounds the cage 8 / and is supported on one end on the cage 8 and on the other side on the intermediate wall 5 of the housing 1.
- the cage 8 is surrounded by a cylindrical release sleeve 12.
- the area of the balls that surrounds the balls 10 Release sleeve 12 has an inner diameter which is selected so that the balls 10 of the cage 8 rest on the inner region of the release sleeve 12. This area extends over a partial area of the length of the release sleeve 12 and determines the elasticity area or the release path of the binding.
- the release sleeve 12 is extended by a toothed rack 14 which passes through the intermediate wall 5 of the housing 1 and is arranged above the slide 9 in the exemplary embodiment shown here.
- the rack 14 is provided with a toothing extending in its longitudinal extent, in which a counter toothing of a pinion 15 engages.
- the pinion 15 is coupled via a gear 16 to an electric motor 17 which is electrically connected to an electronic circuit 18.
- a potentiometric displacement sensor 19 attached to the housing 1, the function of which will be discussed later, supplies the signal to be processed further in the electronic circuit 18.
- the electronic circuit 18 is supplied with voltage via a voltage source 21, which is accommodated in the housing 1.
- a switch 23 is closed, which ensures an electrically conductive connection from the voltage source 21 to the electronic circuit 18.
- the electronic circuit 18 comprises an evaluation circuit 20 and a motor control 22 for the motor 17.
- the trigger mechanism works as follows: partly When a force acts on the slider / 9 in the direction of the arrow F shown in FIG. 1, which is greater than the set force of the spring 4, the partly slider / 9 moves together with the cage 8 in the direction of arrow F in Fig.1. Since the balls 10 are supported on the shoulder 7 of the pull rod 2, the pull rod 2 follows the sliding part movement of the slide 9, as a result of which the spring 4, which is supported at one end on the intermediate wall 5 of the housing 1, is compressed. The spring 11 arranged between the cage 8 and the intermediate wall 5 of the housing 1 is also compressed. The trigger sleeve 12 remains stationary. The displacement part movement of the slide / 9 is now registered by the potentiometric travel part sensor 19.
- the evaluation circuit 20 which also receives the signals supplied by the potentiometric force transducer as a function of the time Determined duration of action, issued a command to control the motor 17.
- the motor 17 drives the pinion 15, which engages with the toothing of the rack 14 of the release sleeve 12, via the gear 16.
- the release sleeve 12 is displaced towards the balls 10 so that they reach the edge 13 of the release sleeve 12 and from the Release shoulder 7 of tie rod 2. As soon as this position, which is shown in FIG.
- the evaluation circuit 20 decides on the delivery of a trigger signal both as a function of the distance covered by the slide / 9 and also depending on the time interval within which this distance is covered. In this way it is ensured that strong shocks occurring on the short side, which are not yet dangerous for the skier's leg, do not lead to triggering.
- the spring 11 which returns the cage 8 to the starting position and on the other hand a reverse rotation of the motor 17 is provided.
- the backward rotation of the motor 17 can also be controlled by the electronic circuit which, for example, causes the backward rotation of the motor 17 after a time interval of a few seconds after the pull rod 2 has been released.
- the trigger mechanism can also release the ski boot in a purely mechanical way. part As soon as the sliding movement of the slide / 9 is so large that the balls 10 reach the edge 13 of the release sleeve 12 and are released from the shoulder 7 of the pull rod 2, the pull rod 2 can reset under the action of the relaxing spring 4, the Slider part 9 is no longer acted upon by the spring 4. Since only a slightly larger path part of the slide is required for the mechanical triggering, a safety triggering is also ensured in this case and injuries to the skier are prevented.
- Another advantage of this trigger mechanism is that an arbitrarily large range of elasticity, which can also be freely selected, is available.
- the release mechanism according to the invention can be used both for a binding system consisting of front jaws and heel holder and for a safety ski binding with a sole plate and holding jaws, for example laterally acting on the shoe sole.
- the release mechanism according to the invention can be used both for a binding system consisting of front jaws and heel holder and for a safety ski binding with a sole plate and holding jaws, for example laterally acting on the shoe sole.
