Definitions

  • safety jaws for safety ski bindings which jaws comprise a detent device, which is disposed between two parts that are pivotally movable to each other, which detent device is unlocked in response to a predetermined, preferably adjustable torque to release said parts for pivotal movement
  • the safety front jaw should be capable of yielding resiliently to a small extent in a lateral direction under the action of short, harmless, lateral shocks, such as occur often during skiing, and that the front jaw should thereafter return to its normal position.
  • the safe control of the ski will not be adversely affected if such short-time, outward pivotal movements of the safety front jaw remain within an angle of about 10.
  • the pivoted member is formed with a bore, the axis of which is parallel to the surface of the ski and which accommodates a piston, which is displaceable against the force of a strong coil spring.
  • the free end face of this piston bears on a suitable fiat of the pivot pin for the pivoted member, which pin is secured to the ski.
  • This piston is urged back against the force of the coil spring during a pivotal movement.
  • this is achieved in that in a jaw of the above-mentioned type, which differs by the detent device from the known jaws having a spring-loaded piston, which have also been described, at least one of the parts which are pivotally movable relative to each other is connected to the associated element of the detent device by a resilient articulated joint affording a limited freedom of movement.
  • the interposition of the resilient articulated joint affording a limited freedom of movement ensures that short-time lateral shocks will result only in a movement of the articulated joint within the angle within which the joint is movable and which can be freely selected, whereas a positive, inelastic connection between the respective member of the safety jaw and the respective element of the detent device will be established when this angle has been exceeded so that the detent device will be unlocked upon a further relative pivotal movement of the two members of the safety jaw if the torsional force acting on the foot is sufiicient to exceed the releasing torque to which the detent device has been set. If this releasing torque is not reached, the resilient articulated joint will return that member of the safety jaw which is pivotally movable relative to the ski back to its normal position.
  • the resilient articulated joint may be provided between a safety jaw member which is'nonpivotally connected to the ski and the associated element of the detent device or between a safety jaw member which is pivotally movable relative to the ski and the respective element of the detent device because the pivoted member of the safety jaw will be returned to its normal position in both cases whenever the detent device has not been unlocked.
  • the resilient articulated joint may be disposed outside the path for transmitting forces acting in the longitudinal direction of the ski.
  • the pivoted member may be mounted on a pivot pin which is at right angles to the ski surface, and the front edge of the sole of the boot may bear under the force of the binding cable against the rear face of said pivoted member.
  • the resilient articulated joint may be arranged in the front portion of the pivoted member, beyond the pivot pin.
  • the pressure exerted by the boot is transmitted by the rear portion of the pivoted member to the pivot pin, which is secured to the ski, so that the resilient articulated joint disposed beyond the pivot pin is not stressed by the forces which act in the longitudinal direction of the ski and might otherwise cause a deformation or fatigue of the resilient articulated joint.
  • the member which carries the detent element may be pivoted by a pivot pin to the pivoted member and may bear on the pivoted member on both sides of the p-i'vot'pin with coil springs.
  • This material particularly soft rubber, the articulated joint is protected from damage caused by mechanical and weather action.
  • the resilient interlayer causes also the pivoted member with the associated element of the detent device to be closed from the outside so that .it gives the appearance of an integral part.
  • that member which carries the detent socket for the detent element secured to the pivoted member may be mounted for a limited pivotal movement against spring force on a member which is non-rotatably connected to the pivot pin of the pivoted member.
  • leaf springs may be secured on both sides to the member provided with the detent socket and may embrace and resiliently bear on the member connected to the pivot pin of the pivoted member.
  • the detent socket may be mounted for a limited displacement again-st spring force in the member which carries said socket, preferably in the baseplate secured to the ski. In such case it will be particularly suitable to provide friction-reducing means, such as rollers or.
  • FIG. 1 is a side elevation showing a first embodiment of a safety from jaw according to the invention for ski bindings. In this view, the parts which are not visible in elevation are shown in dotted lines.
  • FIG. 2 is a top plan view showing the safety front jaw of FIG. *1.
  • FIGS. 3 and 4 are corresponding views showing another embodiment.
  • FIGS. 5 and 6 are corresponding views showing a third embodiment.
  • FIG. 7 is a side elevation similar to FIG. 1 and shows a fourth embodiment of the safety front jaw according to the invention.
  • FIG. 8 is a top plan view showing the safety front jaw according to FIG. 7 with the front portion of the pivoted member omitted.
  • FIG. 9 is a front elevation showing the safety front jaw of FIG. 7. The parts which are not visible are again shown in dotted lines. 7
  • FIG. 10 shows a modification of a detail of FIG. 8.
  • the pivoted member 1 has a sole-retaining projection 2 which extends over the front edge of the sole of a skiing boot 3.
  • the pivoted member 1 is rotatalbly mounted on 'a pivot pin 4, which is riveted into the baseplate 5.
  • the latter is secured to the ski by screws threaded into the screw holes 6.
  • the baseplate 5 has at its front end a detent socket 7, in which the detent ball 8 is locked in the normal position of the pivoted jaw 1.
  • the detent ball 8, its loading spring 9 and the screw 10, which determines the spring pressure and with it the torque for releasing the safety jaw, are not disposed in the usual manner in a bore of the pivoted member 1 but in a separate member 11.
  • the member 11 and the tion of the leaf spring 12, and the rubber material 14 suitably bonded to the end faces of the members 1 and 11 is compressed on one side of the leaf spring and extended on the other.
  • the pivoted member 1 is returned to its central position by the leaf spring 12.
  • the leaf spring 12 and the resilient material 14 are separated by the pivot pin 4 from the point at which the boot 3 is pressed against the safety jaw. The pressure exerted by the boot on the safety front jaw is thus taken up by the pivot pin 4 and does not act on the resilient articulated joint, formed by the leaf spring 12, and the resilient filling material 14.
  • the pivoted member 1 When the foot is under a higher torsional stress, which exceeds the set resistance of the spring 9 so that the detent device is to be unlocked, the pivoted member 1 is again pivotally moved laterally, with a slight deflection of the leaf spring 12, until the resilient material 14 on the corresponding side has been compressed to the limit of its compressibility. The torsional force transmitted by the boot 3 on the safety front jaw will then act fully on the detent device.
  • the pivoted member 1 is rigidly connected to the associated element of the detent device.
  • This element consists again of the detent ball 8, the coil spring 9 and the adjusting screw 10.
  • a member 15 is rigidly connected to the baseplate 5 and the pivot pin 4.
  • This member 15 has the same overall width as the pivoted member 1.
  • the member 15 is disposed substantially only adjacent to the midd e portion of the pivoted member 1 but has a bearing extension, which extends further forwardly approximately in the middle of the height of the safety front jaw.
  • This extension has a vertical bore, through which a pin 17 ex- I tends, to which the member 18 provided with the detent pivoted member 1 are formed in their confronting sur- 1 direction of the ski, and the spring connects the two members 1 and 11 in such a manner that the space a is left between their confronting faces.
  • This space is fil-led with an easily resiliently deformable material 14, such as soft rubber.
  • the boot 3 can be pivotally moved on the ski to a small extent.
  • the pivoted member 1 will pivotally move laterally about the pivot pin 4 whereas the spring 9 retains the detent ball 8 in the detent socket 7.
  • Such slight pivotal movements of the pivoted member 1 cause an elastic deformasocket 7 is pivotally connected.
  • Resilient material preferably soft rubber, is again disposed between the members 15 and 18.
  • Leaf springs 19 are riveted on both sides to the member 18 provided with the detent socket 7 and extend rearwardly to embrace the member 15 and bear resiliently on its side faces.
  • the detent socket 7 and the member 18 follow the movement of the detent ball 8 in this embodiment so that the initial stress of one of the lateral leaf springs 19 is increased and, when the lateral force is discontinued,
  • FIGS. 5 and 6 differs from that of FIGS. 1 and 2 in that the leaf spring 12 between the members 1 and 11 is replaced by a pivot pin 20 similar to the pin 17 of the embodiment of FIGS. 3 and 4.
  • the member 11 has a rearward extension 21.
  • the pivoted member 1 is formed with an opening for receiving this extension.
  • the two parts are pivotally connected by said shaft 20.
  • the pivoted member 1 On both sides of this pivotal connection, the pivoted member 1 is formed with dead-ended holes, which accommodate coil springs 22, which with their ends protruding from the pivoted member 1 bear on the rear face of the member 11.
  • the freedom of movement of the resulting resilient articulated joint is limited to the angle z because the front faces of the pivoted member 1 are wedge-shaped,
  • FIGS. 7 to 9 show a modification of the embodiment of FIGS. 3 and 4.
  • a flat detent plate 23 is pivotally connected by the pin 24 to the baseplate 5 and is formed with the ball socket 7.
  • the baseplate 5 is formed with dead-ended holes 25, which accommodate coil springs 26, which with their free ends protruding from the dead-ended holes 25 bear on the side faces of the pivotally mounted detent plate 23.
  • balls or rollers 27 are disposed below the detent plate 23 to reduce the friction relative to the baseplate 5.
  • the mode of operation of this embodiment is readily apparent from the description of the mode of operation of the embodiment of FIGS. 3 and 4.
  • FIG. shows a modification of the embodiment of FIGS. 7 to 9.
  • the detent plate 28 is not pivoted to the baseplate 5 but is mounted for a displacement transversely to the longitudinal center line of the ski.
  • a safety jaw for safety ski bindings including two jaw parts pivotally movable relative to each other and having disposed therebetween a detent device which is unlocked in response to a predetermined, preferably adjustable torque to release said jaw parts for pivotal movement, the improvement comprising at least one of the jaw parts being composed of two elements, one of which incorporates a portion of the detent device and a resilient articulated joint affording a limited freedom of movement coupling said elements, said articulated joint disposed outside the path for transmitting forces acting in the longitudinal direction of the ski.
  • one jaw part is pivotally movable about a pin mounted at right angles to the surface of the ski with said part being composed of said two elements, and the resiliency. of said articulated joint is afforded by a spring means.
  • the spring means is provided by a leaf spring which extends substantially in the longitudinal direction in a plane which is at right angles to the surface of the ski and which interconnects the elements.
  • one jaw part is pivotally movable about a pin mounted at right angles to the surface of the ski
  • the other jaw part is composed of said two elements, one of said elements is non-rotatably connected to said pin and the other of said elements incorporates the socket portion of the de tent device and is mounted on said one element for a limited pivotal movement against spring means.
  • said spring means is provided by leaf springs secured on both sides to said other element and which embrace and resiliently bear on said one element.
