CA 2247546

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.
