973,161. Ski bindings. H. MARKER. July 19, 1961 [July 21, 1960], No. 26203/61. Heading A6D. An adjustable detent device for constraining movement between a rotatable boot engaging part and a part fixed to or integral with the ski comprises a detent member urged to engage in a recess in one part by a helical spring, the force exerted by the spring being adjustable from a minimum to a maximum value by swivelling or turning a setting device through an angle of less than 360 degrees, the setting device being provided with latching means by which it is selectively latchable in any one of a plurality of angular positions. An eccentric cam 10 pivoting on a fixed plate 14 on the ski presses a ball 6 into a socket 9 in a cheek-plate 3, pivoting on a base plate 1 on the ski and engaging the front edge of the sole of a ski boot. The cam acts upon a member 12 which presses on the ball 7 through a spring 8 in a longitudinal hole in a fixed part 5. The pressure on the ball is varied by adjusting the position of a lever 13 connected to or integral with the cam. A pointed screw on the lever engages in a selected one of a series of recesses 17 in the fixed plate 14. Various other means for varying the pressure on the ball to vary the pressure that can be exerted on the plate 3 before it becomes free to pivot are described. A cam with peripheral depressions which selectively engage a projection on the pressure member is rotatable by a knurled disc. A rotatable rod acting directly on the spring 8 has a projection extending into one of a number of recesses in the side of an inclined slot in the bearing block for the rod or the rod may be eccentrically pivoted on a rotatable lever. The detent device may be arranged on a pivoting member. |
