| Abstract: |
A vehicle mounted parking device for use on a front wheel drive vehicle of the type having motive means and at least two front and two rear wheels. An auxiliary wheel is mounted substantially between and equidistant from the rear wheels and is mounted so as to permit movement relative to the vehicle frame between an out-of-the-way position and a lower operative ground engaging and rear end of the vehicle lifting position such that the rear wheels are raised off the ground. Power means is provided so that the auxiliary wheel may be forced under the rear of the car to raise the rear wheels and to place the rear end weight of the vehicle on the auxiliary wheel. The auxiliary wheel, when in operative position, allows lateral movement of the rear end of the vehicle with a minimum of longitudinal vehicle movement. The auxiliary wheel may be mounted so that its axis of rotation forms an angle between approximately 20° and 60° with the longitudinal center line of the vehicle so that the axis of rotation passes between the front and rear wheel on one side of said vehicle. The rotation of both front wheels by the motive means will cause the lateral movement of the rear portion of the vehicle said auxiliary wheel when said auxiliary wheel is in the ground engaging and rear end of the vehicle lifting position.

First Claim:
Show all 20 claims |
It is claimed that:
1. A vehicle mounted parking device for use on a front wheel drive motor vehicle having motive means, frame means, yieldable means for yieldable supporting the rear end of the vehicle attached to said frame means, rear axle means carried by the yieldable means for yieldably supporting the rear end of the vehicle, at least two rear wheels rotatably attached to said rear axle means, at least two front wheels, steering means for selectively directing the front wheels of the vehicle, and motive means for selectively applying power to certain of the wheels, the device comprising a wheel mount, an auxiliary wheel rotatably supported on said wheel mount, mounting means adapted to be carried by the rear portion of the vehicle for supporting the wheel mount for movement of the auxiliary wheel between an operative ground engaging and rear end of the vehicle lifting position and out-of-the-way position, power means connected to the wheel mount to cause the wheel mount to be moved from the out-of-the-way position to the ground engaging and rear end of the vehicle lifting position, whereby the rear wheels of the vehicle are lifted off the ground and the mounting means for said wheel mount engages the rear axle means and provides support to the rear portion of the vehicle through the yieldable means for supporting the rear portion of the vehicle, and said auxiliary wheel when in said ground engaging and rear end of the vehicle lifting position is disposed substantially between and equidistant from each of the rear wheels and is disposed with its axis of rotation inclined at a substantial angle from the longitudinal center line of the vehicle so that the axis of rotation of the auxiliary wheel passes between the front and rear wheels on one of two sides of the vehicle, said vehicle moving generally in a sidewise direction when the auxiliary wheel is in said ground engaging and vehicle lifting position and when said front wheels are directed by said steering means in a direction similar to the auxiliary wheel and power is applied to the front wheels from the motive means to cause rotation of the front wheels.
