Abstract
A cocking mechanism is disclosed. The cocking mechanism comprises an actuator assembly, a hand crank assembly, and a bow string hook assembly. The actuator assembly further comprises clutch assembly having a bearing housing, a bearing cage, a support axle and bearing elements. The bearing housing is defined by an inner peripheral surface having a plurality of inwardly extending annular ramps, wherein the bearing elements contact a portion of the ramps to prevent rotation of the support axle in a first direction, but allows for rotation of the support axle in a second direction when the actuator assembly is in a locked configuration. This provides for immediate braking action against any unforeseen forward motion of the bow string of a crossbow such as when inadvertently or accidently releasing the removable hand crank assembly during the cocking operation.
