Definitions

  • At least one soleholder member is automatically movable against the resistance presented by at least one resistance element from a locking position to a release position.
  • the resistance presented by the resistance element or elements is a function of the potential energy and kinetic energy.
  • a final control element is provided, which controls the resistance element in response to control signals depending on the kinetic energy.
  • the first part consists of a spring cage
  • the second part of the pendulum arm consists of a headed pin having a head which forms the second spring abutment and also having a shank which extends through the spring the the first spring abutment and which at its free end carries the hob, and the head of the pin acts on the soleholder member or on the 'means' for locking the latter.
  • FIG. 1 is a central longitudinal sectional view showing a toe-holding device
  • FIG. 3 is a top plan view which is similar to that of I FIG. 2 but shows the device in an instantaneous posi- 3 '
  • the illustrated toe-holding device according to the invention comprises a baseplate 1, which is secured to a ski 3 by screws 2.
  • the baseplate is provided with a pivot pin 4, which is shown in FIG. 1 and on which a carrier 5 is pivoted, which held against axial displacement by a disc 6.
  • the latter is secured to the pivot pin by a screw 7.
  • Twolevers 10, 11 are connected to the carrier at pivots 8, 9 and form a four-bar linkage together with a soleholder member 12, which is connected to the levers at pivots 13, 14.
  • Thesoleholder'15 proper is mounted on the soleholder member for a free vertical sliding movement for adaption to boot 'soles differing in thickness and is adapted to be fixed in different posi-' tions by a locking pin 16.
  • the shaft shank has a screw-threaded free end portion on which a pendulum 28 is threaded.
  • a fixing screw may be provided to hold thependulum against rotation.
  • Those arms of the levers 10, 11 which carry the soleholder member 12 are provided at their free ends with respective noses 29 and 30,.which are engaged by the headed pin 27 under the action of the helical compression spring 26 to hold the soleholder member 12 in its normal position.
  • the stress of the helical compression spring 26 is not increased during that last movement so that a seizing of the skiing boot on the ski in oblique position is reliably avoided. Because the stress of the spring is not increased during the pivotal movement of the carrier 5 relative to the baseplate l, the carrier must be swung back to its normal position by hand when it is desired to return the device to a position for skiing. Upon this return of the carrier, the helical compression spring 26 automatically returns the four-bar linkage.
  • a resistance is presented only by the helical compression spring 26.
  • This feature results in a toe-holding device according to the invention in an embodiment which is particularly simple and reliable.
  • the work absorption capacity of the device may be varied, e.g., by the substitution of the helical compression spring 26 by another and/or by a change of the initial stress of said spring.
  • the shock work abs'orption capacity may be varied by changing the position of the pendulum 28 threaded on the headed pin 27.
  • a toe-or heel-retaining device for safety ski bindings comprising a soleholder means in operative relationship with a resistance element (26) which, upon overcoming the resistance of said resistance element, automatically moves from a lock setting to a release setting, the resistance of said resistance element being a function of potential and kinetic energy, said device further including an elastically borne setting element (25, 27, 28) constructed as a pendulum weight in operative relationship with said resistance element for, in dependence upon the momentary deflection of the pendulum weight from a central rest position by forces of mass inertia, influencing said resistance element to oppose movement of said soleholder means, said setting element including a pendulum arm (25, 27) and a pendulum (28) carried by said pendulum arm, said pendulum arm being bipartite, its first part being pivoted to the device and its second part (27) carrying the pendulum, said first and second part operatively forming abutments for said resistance element, and means connecting said second part to said first part such that the second part is
  • a toeor heel-holding device characterized in that said resistance element controlled by the setting element includes a friction coupling.
  • a toeor heel-holding device characterized in that the pendulum arm (25, 27 is movable in the plane of movement of the soleholder member (12) or, even where the soleholder member is constrained to describe a non-spherical path, in a plane of movement which is parallel to the plane of movement of the soleholder member.
  • a toe-holding device characterized in that the resistance element comprises a helical compression spring (26), the first part of the pendulum arm comprising a spring cage (25 the second part of the pendulum arm comprising a headed pin (27) having a head which forms a second spring abutment and also having a shank which extends through the spring and the first sprin abutment and which at its free end carries the pen ulum (28), and wherein the head of the pin is in operative relationship with the soleholder member (12) for locking the soleholder member.
  • the resistance element comprises a helical compression spring (26), the first part of the pendulum arm comprising a spring cage (25 the second part of the pendulum arm comprising a headed pin (27) having a head which forms a second spring abutment and also having a shank which extends through the spring and the first sprin abutment and which at its free end carries the pen ulum (28), and wherein the head of the pin is in operative relationship
