Abstract
A ratcheting device according to the solution comprises a rotatable cogwheel comprising a plurality of teeth, a spring-loaded primary pawl, a spring-loaded handle pawl, a handle comprising a handle pawl disengagement lever, a handle pawl disengagement plate and a primary pawl disengagement plate. The primary pawl disengagement plate is mechanically coupled to the handle such that the handle may be rotated around the cogwheel to a point that the primary pawl disengagement plate contacts the spring-loaded primary pawl and causes it to disengage from the cogwheel. At the same time that the primary pawl is disengaged from the cogwheel teeth by the primary pawl disengagement plate, the handle pawl is similarly disengaged from the cogwheel teeth via contact with a handle pawl disengagement plate. Advantageously, the ratcheting device may be transitioned between a ratcheting state and a free-to-rotate state with only a single hand of the user and without requiring the handle to travel beyond a 180-degree arc of motion.
