Release device for a binding for a boot on a gliding apparatus

Abstract

A release device for a binding for a boot on a gliding board. The device includes a rotatable motor with an output shaft bearing a cam rotatable about a first axis; a lever pivotable about a second axis between a closed position and an open position, the lever having a large crank in contact with the cam, and a small crank; a tripper having at least one control tooth, which is in contact with the small crank when the lever is in the closed position, and at least one release tooth; a rod movable between a closed position and an open position, the rod being provided with a notch in which the release tooth is engaged when the rod is in the closed position. The motor can deliver a torque at its output shaft of less than 2 mN·m, or as little as less than 1 mN·m. The cam includes a plate bearing a cam groove, the cam groove including at least two distinct, contiguous portions, viz., an initial ramp and a release ramp, the initial ramp corresponding to a path of the drive finger substantially along an arc centered on the first axis and a minimal radius of close to zero.
