  • Patent number: 4531715
    Abstract: 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.
