There is provided a jack for raising a wheel of a vehicle and comprising a horizontal base having spaced-apart front end and entry end, and spaced-apart side members extending between the front end and the entry end. A scissors-like lifting mechanism is connected to the horizontal base and has an upper end movable between a raised position at a distance above the horizontal base and a collapsed position near the horizontal base. A force-applying actuator is connected to the horizontal base and to the scissors-like lifting mechanism for actuating the scissors-like lifting mechanism. A wheel tray is connected to the upper end of the scissors-like lifting mechanism for up and down movement thereof between the raised position and the collapsed position. The wheel tray has spaced-apart front portion and entry portion, a bottom surface and a bumper on the front portion. A crossbar is mounted in the scissors-like lifting mechanism for engaging with the wheel tray and for causing the entry portion of the wheel tray to lean down relative to the front portion when the upper end of the scissors-like lifting mechanism is in the collapsed position. The connections of the scissors-like lifting mechanism with the front portion of the wheel tray are differing in height and engagement sequence with the connections to the entry portion for causing the front portion of the wheel tray to lean down relative to the entry portion when the upper end of the scissors-like lifting mechanism is in the raised position.

[ What is claimed is:] [1.] 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.
