Abstract:
A vehicle door lift conversion kit device for vertically opening a vehicle door adaptable to fit a multiplicity of different vehicles, the device comprising:a fixed chassis plate having a pair of adapter plates removably secured thereto, the fixed chassis plate adapted to be installed on a multiplicity of different vehicle types on a vehicle body by attaching to the fixed chassis plate any of a variety of different pairs of adapter plates configured to secure to a door hinge receiving portion on any of a multiplicity of different vehicle types; a double axis connector attached to the fixed chassis plate by a horizontal pivoting means adapted to allow a vehicle door attached to the device to pivot horizontally open and closed and the double axis connector further comprising a vertical pivot linear bearing; a limit means for limiting a horizontal distance that the door may open so that the device is adapted to limit the door to open only a sufficient horizontal distance so that the door is positioned outside of an edge of a roofline of a vehicle above a door opening served by the device; a door attaching arm pivotally attached to the double axis connector by the vertical pivot linear bearing, the door attaching arm having a preformed vehicle specific adapter arm with two elongated door brackets adapted to attach to a vehicle door, the door attaching arm adapted to fit any of a multiplicity of different vehicle doors on different vehicle types by attaching to an attaching bracket any of a variety of adapter arms with elongated door brackets configured to fit doors on different vehicle types; a door lift assisting actuator attached by a first pivot means at one end of the actuator attached to the fixed chassis plate and by a second pivot means at the other end of the actuator attached to the door attaching arm, the actuator acting between the fixed chassis plate and the door attaching arm to assist in vertically lifting the door for smooth easy action in opening and closing the door vertically, the door lift assisting actuator having a means to adjust the amount of lift of the door, and a mechanical limit means to limit the height of lift of the door adapted to act between the door attaching arm and the fixed chassis plate; a safety lock means for maintaining the door in an up position, the safety lock means removably securable between the fixed chassis plate and the door attaching arm to maintain the door in the up position in case the door lift assisting actuator should fail.
