HONEGGER ADJUSTING‘ AND FIXING DEVICE ON SKI BINDINGS Filed March 4, 1937 2,135,895 Patented Nov. 8, 1938 2,135,895 UNITED STATES PATENT OFFICE 2,135,895 ADJUSTING AND FIXING DEVICE ON SKI ' BINDINGS Walter Honegger, Ruti, Switzerland, assignor to Hess & Cie, Pilgersteg, near Ruti, Switzer land Application March 4, 1937, Serial No. 129,061 In Switzerland March 10, 1936 1 Claim. (01. 280-1135) The present invention relates to an adjusting and ?xing device on ski-bindings. This device enables a ?ne adjustment of the toe-jaws and an adaptation thereof to the shoe which can be 5 effected positively and with little expense of time. The accompanying drawing illustrates, by way of example, an embodiment of the invention. Fig. 1 is a plan view of the invention, a part 10 of the covering plate being removed. Fig. 2 shows a cross-section along the line A——B of Fig. 1. - Referring to the drawing in detail, I repre sents a base-plate as ordinarily used on skis, 5 two pairs of spring acting adjusting and ?xing arms 2 being rockably mounted thereon by means of screws 3 which are screwed into the base-plate, said arms 2 being bent at their ?xing end. Each of said arms 2 is provided with a downwardly 20 projecting pin 4. Each toe-jaw 5 has two groups of grooves or notches extending along an arc of a circle and being formed with recesses 6 arranged in pairs, into two opposite ones the pins 4 of the rocked arms 2 may be forced in 25 order to ?x the jaws 5 in their adjusted posi tion. The adjusting and ?xing of the jaws 5 by means of the arms 2 and their pins 4 can be positively effected with great exactness and with little expense of time. When the arms 2 30 are adjusted the pins 4 of the arms 2 are allowed to yieldingly engage with the respective recesses 6 whereupon the jaws rest irremovably in the adjusted position. The adjusting arms 2 may be rigid and in this 35 case they must be lifted for the length of the pins 4 when the jaws shall be displaced after the screws 3 have been loosened. With spring like adjusting arms a loosening of the screws 3 is not necessary. For adjusting, the jaw portions are forced to wards the shoe while the jaws are opened and the ?xing screws ?rmly tightened. Afterwards 5 the adjusting and ?xing arms are rocked and the pins forced into the corresponding recesses 6 whereupon the screws of the adjusting and ?xing arms are tightened. The toe-jaws 5 are positively held in the di- 10 rection across the ski when the adjusting pins 4 are forced into the recesses 6 and the screws 3 are tightened. For displacing of the jaws 5 the adjusting and ?xing arms 2 are rocked into the longitudinal axis of the ski after the screws 15 3 are loosened. The arms 2 may be laminated. Both ends of each toe-jaw being adjustable in the present ski-binding, a very ?ne and pre cise adjustment‘ of the toe-jaws and complete security against all displacements are obtained. 20 What I claim is: An adjusting and ?xing device on ski-bindings, comprising a front pair and a rear pair of ad justing and ?xing arms, a pin on each of said arms, a pair of adjustable toe-jaws of angular 25 section, a group of grooves in each toe-jaw op posite each of said arms, said grooves extending along arcs of a circle eccentric to the rocking axis of the corresponding adjusting arm and diiferent distances from this axis, recesses formed 30 in opposite pairs on the edges of said grooves and adapted to receive said pins, a base plate having a screw between the said adjustable toe jaws, serving as a rocking axis for the said arms and as a means to ?rmly hold the said pin be- 35 tween one or another pair of said recesses.
