  • Grab-activated self-locking winch handle
    Patent number: 7114705
    Abstract: A lock/release mechanism for the crank handle of a winch consists of a set of one or more pins that are captured within the drive head of the handle. Within the drive head is an actuation rod, which acts on these pins. Depending on the position of the rod, the pins are either moved or pushed outward (lock position), or retracted into the drive head (unlock position). The actuation rod is moved by means of a lever that enables removal of the crank handle with one hand.
