International ClassB66D 001/00AbstractThis invention provides a safety mechanism for a winch assembly when storing a load, such as a tire under a vehicle or a boat on a trailer, in a raised or stored position. The invention finds particular application to a spare tire, but those skilled in the art will appreciate the broader benefits of such a structure when used with a winch assembly for other uses such as a boat winch for a trailer or any analogous use wherein it is desirable to secure a load in the raised or stored position.A unique actuator is described with an improvement of the invention, which includes a control path therewith to control a rod end and thereby actuates in a preferred embodiment a latch by converting rotary motion to linear motion.Field of SearchWith vehicle for supporting drumYIELDABLE, CONSTANT ENGAGEMENT, FRICTION COUPLING (E.G., SLIP CLUTCH) IN DRIVE FOR CABLE PULLING DRUM Having stationary mechanism, actuated by load or other obstruction on and traveling with cable, for generating control impulse to rotation retarding means or drive Having cable contacted, supported, or attached mechanism for generating control impulse to retarding means or drive Having mechanism, linked to drum and actuated by number of drum rotations, for generating control impulse to rotation retarding means or drive For rim, tire, or wheel Simple arcuate or rectilinear movement Underslung | |
