发明名称 Winch with storable handle
摘要 A winch for the spooling of a flexible cord and having a collapsable and storable handle and which may be used in a variety of applications, as for example, in the in-line pulling of a rope in a sailboat. The winch generally comprises a spool which is mounted on a frame such as a spindle for rotatable movement. A handle or crank arm is axially shiftable and storable within a bore in the spool and is capable of shifting outwardly of the spool for use. The crank arm is mounted through a hinge mechanism which permits the same to be located in a plane essentially perpendicular to the axis of rotation of the spool. A releasable locking means is provided for releasably locking the crank arm to the spool for causing rotation of the same. A hand grip is hingedly mounted on the crank arm and is telescopically shiftable relative to the crank arm. The hand grip is also capable of being located in essentially perpendicular relation to the crank arm and parallel to the axis of rotation of the spool for purposes of rotating the spool. Another locking means is provided for releasably locking the hand grip to the crank arm when the hand grip is perpendicularly disposed relative to the crank arm.
