Definitions

  • Heel-releasing and heel-holding devices are known which are moved to their clamping position when the boot is stepped into the binding.
  • the known heel-releasing devices comprise retaining belts, which are secured to the binding and slung around the boot.
  • the retaining belt must be slung by hand around the boot or hung by hand into an eye which is secured to the boot so that the skier must stoop down, which is inconvenient. It is an object of the invention to avoid this disadvantage.
  • the invention is based on a retaining device for skis whichare provided with a heel-releasing device, which is secured to the ski and engageable by the application of the heel and which releases the foot in response to an excessive stress which is due, e.g., to a tensile force acting at right angles to the surface of the ski, said retaining device comprising a retaining cable or the like, which is fixed at one end to the ski and at the other end to the skiing boot, one of said ends being releasably fixed.
  • coupling elements are provided for the releasable fixation and automatically interengage in response to the application of the boot and are disengageable only by hand or by another arbitrary actuation.
  • the retaining device according to the invention enables the skier to start skiing immediately when he has stepped into the binding because he need not attach the retaining belt by hand. For this reason, a skier having skis provided with the retaining device according to the invention need only step into the binding and can then start skiing.
  • a coupling member is provided with a locking hook, which is movable against spring force to the open position by an oblique run-up surface upon the engagement of the other coupling member, and is subsequently movable by the spring force into the locking position, and is provided with an actuating member for an arbitrary movement of the hook into the open position.
  • the actuating member is operatively connected to the opening lever of the heelreleasing device so that upon an arbitrary release of the heel-releasing device the retaining device according to the invention is released too whereas the releasing lever will not be operated and the retaining device according to the invention will continue to connect the foot to the ski.
  • one coupling element consists of two relatively movable hook members, which together form an eye and are springbiased toward their closed position, the movable hook member is provided with the run-up surface for a pivotal movement into the open against the spring action upon the engagement by the other coupling element, which in the closed position is locked in the eye, preferably with a large backlash, and the movable hook member is provided with the actuating member for its pivotal movement to the open position or cooperates with such actuating means.

  • the part in the form of a hollow-spherical segment is preferably provided with an extension, which forms a run-up path for the detent ball.

  • a retaining device wherein the coupling element mounted on the boot has two limbs, which are at an angle to each other to form a V and are provided with openings for the passage of the other coupling element, which is secured to the retaining cable and has a U-shaped forked frame having a cross-piece to which the retaining cable is linked whereas the limbs of said forked frame are connected adjacent to their free ends by a pivot for a locking hook, which has a nose which can be passed through the openings in the limbs forming a V-shaped angle and engages the top of the rim of the passage opening.
  • a retaining device wherein the locking hook is pivotally movable to the release position by a slider, which is slidably mounted in the releasing device and preferably engages an angled extension of the locking hook.
  • a retaining device wherein a crank drive is provided for actuating the slider and the crank of this drive is rigid with an actuating extension, which extends over the opening lever of the releasing device.
  • a retaining device wherein the coupling element provided on the boot consists of a detent ball, and a part in the shape of a hollow-spherical segment for cooperation with the detent ball is provided on that coupling element which is connected to the retaining cable, said part in the form of a hollow-spherical segment being pivotally movable against the force of a spring.
  • a retaining device wherein the part in the form of a hollow-spherical segment which is provided on the coupling element connected to the retaining cable is provided with an extension, which forms a run-up path for the detent ball.
