摘要

A strap tensioning device has a reel rotatable by a pawl and ratchet mechanism manually operable by a crank arm pivoted on a frame. Release of a detent pawl holding the reel against unwinding is effected by manual movement of a stop normally limiting the return stroke of the crank arm. The stop when so moved can releasably secure the crank arm to the frame in position to release the reel.
