DEFINITION

Classification: 180/199

WITH POWERED, GROUND-ENGAGING MEANS FOR PRODUCING, OR ASSISTING IN THE PRODUCTION OF, LATERAL MOVEMENT OF THE VEHICLE (E.G., FOR PARKING):

(under the class definition) Vehicle provided with powered means for engaging the ground and lifting one or more of the vehicle's ground contacting members to relieve it of all or a part of its load and then either (1) transporting, while supporting, the one or more members in a sidewise direction, or (2) exerting, while at least part of the load is relieved, a sidewise thrust on the portion of the vehicle with which the one or more members are associated, or (3) supporting, after lifting, the one or more members, which members are at one end of the vehicle, for relatively friction-free sidewise movement (e.g., as on casters) and then cooperating with the motor of the vehicle to produce the sidewise movement of the members, and a resultant swinging of the vehicle, when (a) power is applied to the vehicle's two, driven, ground-contacting members at its other end and (b) the appropriate one (depending upon the direction of swinging desired) of those two members is braked against rotation and thus utilized as a point of pivot for the swinging of the vehicle.

(1) Note. While vehicle movement of the kind provided for herein finds its most common application in the "parallel" parking of the vehicle, it is not infrequently utilized in turning the vehicle end for end.

(2) Note. A device or element for preventing sagging of a wheel and its suspension members, at such time as the portion of the vehicle to which they are attached is elevated, appears frequently in the art of this and the indented subclasses.

(3) Note. Certain motor vehicles, which are merely reducible in overall dimensions for a storage (e.g., parking) or transport purpose, will be found in subclass 208 below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

208, for a motor vehicle of the special wheel base type, which vehicle is of a collapsible or knockdown nature, and see (3) Note above.

236, for a motor vehicle having four wheels driven and wherein is provided means for steering all of the driven wheels and further wherein that means enables the vehicle to travel in a path which is other than that produced by turning the front wheels and the rear wheels substantially equally and oppositely (e.g., if each wheel is turned 90 deg. about its axis of pivot, the vehicle will move sideways).

254, Implements or Apparatus for Applying Pushing or Pulling Force,

418+, for a vehicle-attached jack for lifting the vehicle. The powering of the jack, not only during its lifting movement but also for driving a wheeled jack relative to its supporting surface, by the motor of the vehicle being lifted is not foreign to the art of that subclass (418); however, to be proper therefor, the lifting should be limited to that performed in conjunction with repairing or servicing the vehicle.

280, Land Vehicles,

761, for a land vehicle provided with an attachment in the nature of a manually-actuated device for assisting in the parking of the vehicle in "parallel" fashion. If the device is a jack which is powered during lifting by the motor of the vehicle, classification is in this class (180), but, in the absence of powered lateral movement of the vehicle, is not in this area (subclasses 199+).
