Toe iron for safety ski bindings

Abstract

Abstract 1,142,169. Toe-iron for safety ski bindings. H. MARKER. 24 May, 1966 [4 June, 1965], No. 23181/66. Heading A6D. A toe-iron for safety ski bindings is characterised by the combination of all the following features: (a) a sole-retaining member is braced through a bearing means, against a guide surface extending transversely to the longitudinal direction of the ski; (b) the length of the guide surface extending transversely to the longitudinal direction of the ski corresponds approximately to the range of foottwist occurring during harmless lateral-jolts; (c) adjacent to the guide face running transversely to the longitudinal direction of the ski are guide faces which are inclined sharply forwardly on both sides, and (d) the soleretaining member is, in every position, subject to the action of one or more return springs. In one embodiment the toe-iron comprises a base part 1 fitted rigidly on the ski; a soleretaining member 2 having a beaded edge 11 which engages over the front edge of the sole, also having flanges 18 and 19 which fit over the projection 15 and is guided and held by bolts 6 and 7 in the groove 3; and a spring element 9 guided and held in part 1 by the bolts 10; the two ends of the spring 9 engage with the sole-retainer 2 via the bolts 6 and 7. The sole-retainer 2 is capable of moving initially only transversely to the longitudinal direction of the ski and to ensure this two guide projections 12 and 13 are provided between the flanges 18 and 19, and are braced against the projection 15. In the extreme pivoted position it is possible for the soleretainer 2 to execute a forward pivoting movement. Other embodiments are described in which (a) the sole-retainer is not a self-contained component but is comprised of two angles which are connected with each other through angle arms; and (b) the sole-retainer is guided longitudinally with respect to the ski in a groove of a sliding block which for its part can only move transversely of the longitudinal direction of the ski, the longitudinal movement of the sole-retainer being governed by the position of the sliding block with respect to the guide face of the housing.
