  • Patent number: 7007346
    Abstract: A multi-axis automobile door mount providing a combination of swing-out and vertical-lift motion suitable for retrofitting a conventional swing-out automobile door for vertical-lift operation. The door is opened from a closed position in the conventional swing-out movement about a swing-out hinge. At a predetermined swing-out angle of the door to the automobile body, the door is moved in an upward vertical direction about the vertical-lift hinge. The door is closed by lowering the door to the horizontal orientation and closed in the conventional swing-in manner. A vertical-lift door system is provided to substantially incorporate the movement of a vertical-lift door with an integrated system of one or more hinges and lift assist devices. The lift assist devices provide for, singularly or in combination, among other things, controlled and deliberate movement of the door, power-assisted door operation, and/or easier integration and assembly onto the automobile.
