Definitions

  • ABSTRACT A ski binding is combined with one or several discs of plastic material inserted between the sole of the ski boot and the ski boot supporting surface of the ski.
  • the discs are provided with diametrical bores through which a cable is passed which extends longitudinally of the ski between the boot and the ski surface.
  • the cable passes through guides secured to the ski at both ends of the ski boot and is extended to form a loop about the upper of the boot.
  • one end of the cable is attached to the ski adjacent one end of the boot and the other end is attached to the ski boot.
  • a ski binding for releasingly connecting a ski boot to the ski comprises a friction reducing disc of plastic material arranged between the sole of the ski boot and the surface of the ski, and a flexible pull member connected to said disc for holding the disc freely movable on the ski. In this manner, the influence of variable friction on the release of the binding is widely eliminated and a greater safety is obtained.
  • FIG. 1 is a view in elevation of a first embodiment of a ski binding according to the invention
  • FIG. 2 is a plan view of this embodiment
  • FIG. 3 is a fragmentary plan view of a modification of the ski binding according to FIGS. 1 and 2;
  • FIG. 4 is a view in elevation of a second embodiment of a ski binding according to the invention.
  • FIG. 5 is a plan view of this second embodiment
  • FIG. 6 is an elevation of a third embodiment of a ski binding.
  • FIG. 7 is a plan view of this embodiment.
  • a ski boot 1 is secured to the ski 4 in a manner known per se.
  • the front of the boot is held by means of a fore clamp 2 allowing sideward release and the back is held by means of an automatic heel locking means 3.
  • Two discs 5 consisting of plastic material, e.g., Teflon, are located between the sole of the boot and the surface of the ski.
  • the two discs are provided with a diametrically running bore through which a flexible cable 6 is passed.
  • the discs 5 are either clamped or otherwise fixed to the cable 6 or the bores may be of such diameter that the discs may longitudinally slide along the cable.
  • the cable 6 traverses the front clamp 2 and at the back it traverses the automatic heel-locking means 3.
  • the cable 6 is bent up at both ends of the boot and forms a closed loop passing along one side of the ski boot upper. It is connected with a branch cable 7 which passes around the other side of the ski boot and is detachably connected'to the cable 6 by means of a spring safety hook 8.
  • the ski boot as may be seen immediately from FIG. 1, remains connected with the ski whenever the binding releases from the boot, so that the ski cannot run away from the boot.
  • the cable '6 may be provided with a resilient helical wire sheath for stabilization and protection purposes.
  • the end of a cable 9 passing through the automatic heel locking means 3 is attached to one end of a compression spring I having its other end fixed to a support 11 on the ski 4.
  • the discs fitted tightly to the cable 9 thus may easily move on the surface of the ski 4 whenever the binding is released, the spring 10 tending to return the disc 5 into their original position.
  • the front end portion of the cable is arranged to form a detachable loop about the boot upper, as shown in FIG. I.
  • a resilient support of the cable 9, such as spring 10 could also be provided at the front of the ski boot or even at both the front and rear ends. Also, the cable could be constructed to be resilient itself.
  • the two discs 5 are arranged on two parallel cables 12 and 13. One end of each cable passes through the front clamp 2 and is secured thereto. Within the rear disc 5, the cables 12 and 13 separate laterally to both sides of the ski and each cable end is provided with a ring 14. Belts 15 passing round the upper of the ski boot 1 engage these rings 14, so that both cable ends thus are secured to the ski boot I.
  • the discs 5 are again arranged on two parallel cables 16 and 17. One end of each cable passes through the automatic heel locking means 3 and is secured thereto.
  • the two cables l6, 17 separate towards both sides and are then connected together at 18.
  • One cable 16 is extended beyond this point of connection 18 and is provided at its end with a spring safety hook 19.
  • the cables l6, 17 are passed from the front disc 5 over the front portion of the boot, and the extension of the cable 16 will be passed around the upper of the boot 1 and, secured to boot by means of a spring safety hook 19 whereby the cable forms a connection between the ski-boot l and ski 4; whenever the binding releases the ski cannot run away.
  • the cables holding the plastic disc could be secured to the ski boot at the front and rear portions of the sole or at both sides, so that the discs would be firmly connected to the ski boot.
  • Teflon discs instead of two Teflon discs, only one or also three such discs could be arranged between the sole of the ski boot and the ski in position by means of a flexible cable or other pull member.
  • Teflon discs which could also be square or rectangular instead of circular, as shown, reduce the friction between ski boot and supporting surface of the ski and therefore permit a more uniform release of the binding.
  • a ski binding for releasingly connecting a ski boot to a ski comprising two friction reducing discs of plastic material arranged on the ski boot supporting surface of the ski in longitudinally spaced relation of the ski and forming the support of the ski boot, said friction reducing discs being arranged between the sole of the ski boot and the surface of the ski, said friction reducing discs being each provided with a diametral bore, a flexible pull member connected to said discs for holding the discs freely movable on the surface of the ski, holding means for said pull member on the ski, at least one end of the pull member being extended beyond said holding means, and means on said extended portion for securing the end thereof to the ski boot, a cable defining said flexible pull member passing through the bores of said discs in a direction longitudinally of the ski, said holding means comprising guide means for said cable fixed to the ski at either end of the ski boot, said cable having portions passing beyond said guide means for attachment to the ski boot.
  • a ski binding for releasingly connecting a ski boot to a ski comprising a friction reducing disc of plastic material arranged between the sole of the ski boot and the surface of the ski, a flexible pull member connected to said disc for holding the disc freely movable and positionally adjustable on the surface of the ski in the longitudinal direction thereof, holding means for said pull member on the ski, at least one end of the pull member being extended beyond said holding means, and means on said extended portion for securing the end thereof to the ski boot.
