BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a safety ski binding comprising an electronic evaluating circuit which is connected to a force-receiving means giving off electrical signals, an electrical current supply, for example a battery, and an electromechanical release member driving a control element, which latter controls a locking mechanism engaging a movably supported sole-down-holding means, and the electromechanical release member is arranged at least with one part of the control element in a tightly closed housing of a control block, and with the control element being designed as a shaft snugly guided through the wall of the housing.
BACKGROUND OF THE INVENTION
Such a safety ski binding became known from AT-PS 386 961 (corresponding to U.S. Pat. No. 4,880,252) and has been successful because the danger of an icing up of the sensitive release member is avoided by the tight shielding of the electromechanical release member. The known solution provides an electromagnet with a flap anchor as the electromechanical release member on which a locking system is supported, which, when the anchor has dropped off, holds the control element in its rest position so that also the locking mechanism of the jaw can be held in its locked position.
SUMMARY OF THE INVENTION
The goal of the invention is to provide an improved safety ski binding of the abovementioned type such that it is distinguished by a high degree of insensitivity of its release characteristic with respect to the accelerating forces occurring during skiing and acting on the release mechanism, or rather that these forces do not influence the release behavior of the ski binding.
This is achieved according to the invention by the electromechanical release member being an electric motor which controls--preferably through a gearing--a locking system blocking and releasing the shaft serving as the control element.
These measures result in the advantage that accelerating forces can have practically no influence on the release of the jaw since the motor, as soon as it is supplied with voltage through the evaluating circuit, starts to rotate and initiates the release. A reaction by the accelerating forces which act onto the individual parts of the locking system and the motor stays within practically negligible limits, in particular when the motor controls the locking system through a gearing. This results in a release characteristic of the safety ski binding which is practically independent from the accelerating forces acting onto the release mechanism.
AT-PS 319 110 already discloses a safety ski binding in which the release member is an electric motor, however, the motor in this known solution acts through a cable line directly onto the locking member. The motor and the cable line are thereby arranged practically unprotected in the housing of the jaw. Furthermore, the motor must produce the entire release force and must therefore be of a suitable size and, in addition, the danger of icing up, in particular an icing up of the cable line, must also be taken into consideration so that in the known case a corresponding demand for current for the motor exists.
In the solution of the invention, the motor is arranged in a tight housing of a control block and acts onto the locking system which in turn blocks or releases the locking mechanism and can be designed, for example, according to AT-PS 388 110 or AT-PS 387 909, so that the motor need only produce small control forces and can therefore be very small and use only little electrical energy. Thus a small battery is sufficient.
A further characteristic of the invention provides that the locking system is a gear mating with a pinion driven by the electric motor and being connected fixed against rotation to a crank, to which a pull rod is hinged. The pull rod is hingedly connected to a pivotally held lever which, in the locked position, supports the shaft serving as the control element against the force applied by the locking mechanism of the jaw.
