Abstract:
A jack for raising a wheel of a vehicle, comprising:a horizontal base having spaced-apart front end and entry end, spaced-apart side members extending between said entry end and said front end, and longitudinal and transversal dimensions;a scissors-like lifting mechanism mounted to said horizontal base and having an upper end movable between a raised position at a distance above said horizontal base and a collapsed position near said horizontal base;a force-applying actuator connected to said horizontal base and to said scissors-like lifting mechanism for actuating said scissors-like lifting mechanism;a wheel tray connected to said upper end of said scissors-like lifting mechanism for up and down movement thereof between said raised position and said collapsed position; said wheel tray having spaced-apart front portion and entry portion, a bottom surface and a bumper on said front portion;a means for lowering said entry portion of said wheel tray relative to said front portion, connected to said scissors-like lifting mechanism and to said wheel tray, for lowering said entry portion of said wheel tray relative to a position of said front portion when said upper end of said scissors-like lifting mechanism is in said collapsed position, said means for lowering said entry portion of said wheel tray relative to said front portion comprising a crossbar mounted in said scissors-like lifting mechanism and acting against said bottom surface of said wheel tray, and;a means for lowering said front portion of said wheel tray relative to said entry portion, connected to said scissors-like lifting mechanism and to said wheel tray, for lowering said front portion of said wheel tray relative to a position of said entry portion when said upper end of said scissors-like lifting mechanism is in said raised position;such that said wheel tray is inclinable downward toward said entry end of said horizontal base for facilitating a rolling of a vehicle wheel therein when said upper end of said scissors-like lifting mechanism is in said collapsed position, and such that said wheel tray is inclinable downward toward said front end of said horizontal base, for urging a vehicle wheel against said bumper for preventing said wheel from rolling out of said wheel tray when said upper end of said scissors-like lifting mechanism is in said raised position.
