<p>827,119. Skis. GERTSCH, E. Feb. 11, 1958 [Feb. 14, 1957], No. 4479/58. Class 132(1) A ski-stopping device comprises a brake lever pivoted to the ski which, on release of the ski-fastening moves from an ineffective to an effective position protruding downwardly beyond the sliding surface of the ski to brake the detached ski. Ski-boot 2 has bolts 20 at its front and rear by which it is held in a safety binding comprising a front part 3 and a rear bolt 22 both secured to the ski 1 . Bolt 22 is movable manually against the tension of a spring 21 by a lever 23. A lever 6 of stiff sheet material is pivoted on a pin 5 mounted in members screwed to the sides of the ski and is biased to its vertical position, chain dotted lines Fig. 1, by a torsion spring. The rear arm 6a of the lever 6 carries a transverse terminal portion 6b which during skiing is held against the ski by the toe of the ski-boot thus holding lever 6 in its inoperative position. When the boot is removed suddenly, e.g. when the skier falls, the lever is released, end 6c engages the snow and the ski is prevented from sliding away. The lever may be locked in its inoperative position during transport by the end of a part slidable by means of flap 9a in grooves 10a in a member 10 secured to the ski and having a part 10b which covers pivot 5 and sping 7 (Fig. 2, not shown). As shown in Fig. 3, boot 2 is retained in a foot plate 13 at whose front end there is a pin 14 engaging a recess in a support 15 adjustably fastened to ski 1 by longitudinal slots. Hinged to a lateral part of support 15 there is a brake lever 17 spring biased to the position shown in chain dotted lines and having an extension 19 normally held under foot plate 13.</p> |
