US12546557 - Crossbow crank and related method of use
A crossbow crank can comprise a drive shaft selectively coupled to a one-way bearing that allows rotation of the drive shaft and an associated spool in a first direction, and impairs rotation of the drive shaft and the spool in a second direction. The drive shaft can be automatically locked and unlocked relative to the one-way bearing, allowing the bearing to control operation of the drive shaft, via a brake. The brake can be axially compressible along the drive shaft to automatically lock the drive shaft and a sleeve so they are fixed relative to one another and rotate in unison when the drive shaft is rotated in the first direction. The brake can be deactivated by operation of a crank so that the drive shaft can rotate freely relative to the sleeve and thus the bearing in a second direction. A related method of use is provided.
