1,188,554. Ski bindings. H. MARKER. 17 Aug., 1967 [5 Sept., 1966], No. 37982/67. Heading A6D. A toe piece for safety ski bindings suitable for downhill and cross country skiing comprises a fixed member I adapted to be secured to the ski forwardly of the ski boot, a pivot pin 5 mounted on the fixed member for transverse displacement from the longitudinal axis of the ski, the pin 5 being perpendicular to the surface of the ski, a spring 11 operatively connected between the fixed member and the pin to resist relative movement between the pin and the fixed member, and a pair of rearwardly extending sole-holding members 6, 7 for receiving therebetween and engaging the ski boot, the sole-holding members being mounted on the pin and being held against pivotal movement when the pin is in the normal position relative to the fixed member but being free to pivot thereabout when the pin is displaced laterally a predetermined distance to either side of the normal position against the bias of the spring. The spring may be a compression or helical coil spring or gas spring and is mounted in a transverse recess 10 in the fixed member each end of the spring engaging a fixed abutment 13. The pivot pin and sole-holding members are mounted on a carrier 4 which is slidably retained in the fixed member e.g. by guide roller 19 in transverse groove 18, the carrier being further provided with guide rollers 20 and 21 operating on cam 22 and extending members 14, 15 engaging each end of the spring. Transverse displacement of the pin causes compression of the spring tending to return the pin to the normal position but when displacement exceeds a predetermined distance one of the rollers 20 or 21 moves free of the cam 22 thereby enabling pivotal movement of the respective sole holder about the pin with release of the boot from the binding.
