ABSTRACT:
The brake is of the type in which a spring wire bale is held down against the ski by a ski-boot inserted into the ski-binding. The bale pivots at the rear of the binding and from there extends into brake spurs which, when the bale is held down, extend above, and parallel to the ski. When the bale is released, it pivots the brake spurs down into the snow to stop the ski. The spring action is provided by spiral springs which pass from the brake arms of the bale over a cam surface of a trunnion and then again to the brake arms where the brake spurs begin. An adjustable device for fixing the trunnions to the ski with shanks are described. Special contouring of the cam surface and corresponding curvature of that part of the brake arm which pivots on the cam surface permits the spurs to be raised above the upper ski surface when the bale is down. Detents in the shanks permit the spurs to also be moved inwardly in this position. Alternative structures for the trunnions and also for the use of a leaf spring in place of the spiral spring are described.
