This invention provides a safety mechanism for a winch assembly when storing a load, in a raised or stored position, such as a tire under a vehicle or a boat on a, trailer. 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 ensure the confining of a load in the raised or stored position.

Why it's free to use
- Filed January 10, 1991 and granted July 5, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 10, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 10, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
