Abstract
An automated hoist for a vehicle spare tire includes a linear bracket mounted beneath the vehicle chassis, proximal the rear bumper. A motorized housing can be automatically propelled backward or forward along the bracket. A retractable cable extending from the housing has a lifting plate at a distal end that is connected to the spare tire. When a driver engages a switch, the cable partially lowers the spare tire and the housing moves toward the rear of the vehicle. The cable is then completely lowered until the tire is at ground level and the lifting-plate automatically releases the tire.
Claims2
An automated hoist for a vehicle spare tire comprising:
- a linear bracket mounted beneath a vehicle chassis;
- a housing slidably mounted on said bracket;
- a cable depending from said housing, said cable having a distal end attached to a spare tire;
- means for extending and retracting said cable,
- means for releasing said tire from said cable wherein said means for releasing said tire from said cable includes a lifting plate at a distal end of said cable, said lifting plate having a pair of spring-biased arms extending outwardly therefrom, beneath said spare tire;
- a solenoid received within said lifting plate and connected to said arms;
- and a controller means for commanding said solenoid to retract said arms;
- means for moving said housing along said bracket, wherein said means for moving said housing along said bracket includes a series of apertures longitudinally positioned along said bracket;
- a gear attached to said housing and engaging at least one of said apertures;
- and a motor connected to said gear for rotating said gear in either of two directions whereby a user can lower the spare tire, move said spare tire toward the rear end of the chassis and release said tire from said cable to facilitate changing a flat tire.
