Abstract
A ski brake for a ski embodying two brake vanes pivotable from a preparatory position above the running surface of the associated ski downwardly into a ski braking position. The brake vanes also can be retained against the action of springs in a position above the ski running surface in a so-called arrested position for storage and transport of the skis. Movable latch bolts cooperate with the brake vanes to ensure that the arrested position is assumed only when the ski boot is released from the ski. A pressure plate engageable by the ski boot and connected by a cable to the latch bolts moves the bolts to shift the ski brake automatically from the arrested position into the preparatory position when the ski boot is secured to the ski.
Claims14
A brake mechanism for skis having a running surface, comprising two brake vanes, means pivotably mounting said brake vanes for movement from a position above the running surface of the ski downwardly into a ski braking position, spring means acting upon said brake vanes to bias said vanes into the ski braking position, and latching means for holding the brake vanes in an arrested position for storage and transport of the skis and in a preparatory position when the skier's ski boot is secured to the ski, said latching means comprising for each brake vane a bushing, said bushing being beveled at its end, each brake vane having a bore for receiving the bushing, a spring biasing the bushing, each said bushing being urgable against the force of the spring towards the base of the bore of the associated brake vane, a bolt provided for each bushing, a yoke interconnecting said bolts, a first web extending transversely across the ski, each bolt possessing a tapered end of lesser diameter than the inner diameter of the bushings and arranged to be axially displaceable in said first web in alignment with the associated bushing, said first web being provided with bores for receiving the bushings in the arrested position of the ski brake and for taking-up the bolts, control means for the ski brake, the brake vanes in the preparatory position having the bushings forwardly displaced out of the first web against the action of the control means such that the bolts enter the bushings, push such out of the bores of the first web and fixedly hold such in an eccentric position with regard to the axes of the bolts, said yoke interconnecting the bolts being connected between the bolts to a traction rod extending in the lengthwise direction of the ski, said traction rod having a free end, a lever having an intermediate portion, means for supporting the lever at one end, means for pivotably connecting the intermediate portion of the lever to the free end of the traction rod, a traction element extending along a side edge of the ski with which there is connected the other end of the lever, said traction element being shiftable in its lengthwise direction by the control means which can be activated by the ski boot.
A brake mechanism for a ski having a running surface, said brake mechanism comprising two brake vanes, means pivotably mounting each brake vane for movement from a position above the running surface of the ski downwardly into a ski braking position, spring means acting upon said brake vanes to bias said vanes into the ski braking position, latching means for holding the brake vanes in a preparatory position when the skier's ski boot is secured to the ski, control means for the brake mechanism, said latching means comprising a web extending transversely across the ski, said web having bores, a bolt provided for each brake vane for releasing the brake vane from its preparatory position to its braking position, said bolts being axially guided and displaceable in the bores of said web, a yoke interconnecting said bolts, a traction rod extending in the lengthwise direction of the ski and connected to said yoke between said bolts, said traction rod having a free end, a lever having two ends and a central portion, one end of said lever pivotably supported adjacent one side of the ski, means pivotably connecting said central lever portion with the free end of said traction rod, a traction element having two ends and extending along the other side of the ski, one end of said traction element connected to said control means, the other end of said traction element connected to the other end of said lever, said traction element being shiftable in the lengthwise direction thereof by said control means to permit release of said brake vanes by said bolts.
