ABSTRACT:
A ski brake having a ski mountable base plate and having a pair of braking arms, each braking arm having a disk-shaped head at one end and being supported intermediate its ends on the base plate for limited pivotal and axial movement about an axis normal to the arm and transverse of the ski. A bearing bar is pivotally supported in the base plate about the axis, and a pedal is pivotally supported on the bearing bar at a location remote from the axis. A receiving recess is provided in each lateral side of the pedal and defines a guide surface which forms an acute angle with the ski surface when the ski brake is fully retracted. Each disk-shaped head is supported for pivotal movement about its axis on a respective guide surface with a side thereof disposed against and parallel to the guide surface. The undersurface of the pedal includes a flattened surface extending forwardly from beneath the pivot axis and upwardly at an acute angle to the rest of the undersurface. The pivotal movement of the pedal on the bearing bar as the ski brake is pivoted to a retracted position acts on the disk-shaped heads through the guide surfaces to pull the braking arms laterally inwardly to a position above and parallel to the ski.
