ABSTRACT:
A windshield jack includes a linear actuator operable between retracted and extended conditions. The actuator includes telescoping inner and outer tubes. A reversible drive motor connected to the outer tube includes a threaded drive shaft which engages a the inner tube, a base member for positioning on the front seat of a vehicle, and a windshield contact member to engage the windshield. Motor rotation in one direction moves the inner tube to extend the actuator. Motor rotation in the opposite direction moves the inner tube to retract the actuator. The base member may be a straight crossbar, a foot pad, or a bowed crossbar. The windshield contact member may be a crossbar, a suction cup, or a crossbar with suction cups along it.
