    • 1,146,495. Toe-iron for safety bindings. H. MARKER. 27 May, 1966 [3 June, 1965], No. 23970/66. Heading A6D. A toe-iron for safety ski-bindings is characterised in that it can be swivelled about a vertical axis lying in the area of the heel, out of its normal position until it reaches either of two release positions without longitudinal movement, and does not release the foot until this angular position has been overstepped whereby the resistance of the spring is transmitted through at least one lever and an abutting member of the toeiron, which slides upon an edge of the lever when swivelling occurs, the lever and the spring being so constructed that when the swivelling occurs, the increase in the resisttance of the spring is approximately compensated for by the elongation of the lever arm between the lever fulcrum and the bearing point of the abutting member. In an embodiment, a long base plate 5 is arranged to rotate about a round plate 6, which is securely mounted on the ski 19 and lies in the region of the heel, the sole holder 7 being securely fastened to the base plate 5. A restoring mechanism comprises a cam plate 10 with a cam 24 which is held in its initial position by spring 15, and the roller 18 is supported in the pivot bearing 16, the pivots 11 and 12 being located in the end position of their associated guide slots 22 and 23. When the base plate is swivelled cam plate 10 will rotate about one of the pins 11 and 12 and the roller 9 will ride upon cam 24. The plate 5 can swivel freely about point 6 after release from the restoring mechanism. The member 8, in which roller 9 is supported, may be swivelled vertically about an axis 20 so that base plate 5 may be easily reintroduced into the restoring mechanism. Other embodiments are described in which (a) torsion springs are employed as the restoring element, whose free ends collaborate in each case with an abutting member of the toeiron and a fixed stop on the ski, and the sole holder member is pivotably supported on the swivelling plate and locked so that it cannot swivel until it reaches the predetermined angular position; and (b) bellcrank levers are employed as the restoring element, preferably pivotable about a common fulcrum, and which collaborate with one pressure or tension spring each and whose free lever arms lie around and bear upon the abutting member of the toe-iron.
