1,195,043. Ski-bindings. H. MARKER. 18 Aug., 1967 [14 Sept., 1966; 5 July, 1967], No. 38117/67. Heading A6D. A step-in heel holder for safety ski-bindings comprises a carriage 105 adapted to be mounted on the surface of the ski immediabely behind the heel of a ski boot, a carrier for a sole holder and pedal assembly mounted on said carriage for pivotal movement about an axis parallel to the surface of the ski from an open position ready to receive the heal of the ski boot as it is inserted into the binding to a closed position in which the heel is held in the binding against the surface of the ski, said carrier comprising upper and lower lever arms 118, 119 extending forwardly from said pivot axis and being pivotable relative to each other about said axis against the pressure of a spring, a sole holder 115 and pedal assembly 116 connected to the forward end of one of said lever arms for engagement with the heel of the ski boot; when inserted in the binding, and a catch adapted to hold the other of said lever arms, when the carrier is in the closed position, against pivotal movement about said axis, said catch being manually releaseable to permit voluntary disengagement of the ski boot from the binding and being automatically released by a predetermined upward displacement of the sole holder relative to the surface of the ski and pivotal movement of said one arm relative to the other against the pressure of said spring. The position of the carriage is adjustable in the longitudinal direction of the ski to accommodate differently sized ski boots by a screw mechanism 107. In particular embodiments in Figures not shown, the catch mechanism comprises empirically of (i) a toggle linkage constituted by two congruent over centre levers each consisting of two lever arms 121, 132 linked at the knee by pivot pin 133, (Figs. 1-4), (ii) a toggle joint consisting of two lever arms 162, 163 and a screw 164 (Figs. 5-8), modifications of which are given in Figs. 9-10, (iii) a pivotally mounted locking lever 13 (Figs. 11-12) and Figs. 13-16 illustrate a modification of (iii) wherein a resilient contact pressure of the skiing boot against a toe-holding device is generated.
