DEFINITION

Classification: 280/6.15

BODY ELEVATION OR TILT:

(under the class definition) Vehicle comprising means disposed between that portion of a land vehicle which operates as a load, load carrier, or receptacle and running gear for vertically predisposing the load, load carrier, or receptacle at a distance from either the land surface or from the running gear to achieve change in height or level.

(1) Note. Running gear is defined as the structural assembly connecting ground-engaging means (e.g., runner, skid, sled, wheel) to a vehicle body, chassis, or frame, inclusive of axle, control arm, link, shock absorber, spring,

strut, etc.

(2) Note. Means for vertically positioning a wheel relative to running gear for the purpose of altering a dimension of the vehicle or a part thereof is not proper for classification in this subclass or subclasses indented hereunder. Such subject matter is provided for later in the class schedule.

(3) Note. The means changes height or levelness for other than transient excursions. Adjustment or establishment of riding or suspension height of a vehicle body, chassis, or frame in response to a force encountered while the vehicle is executing surface travel is provided for earlier in this class (Class 280).

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.503, for an active suspension involving plural diverse control criterion one of which may be riding or suspension height adjustment.

5.514, for riding or suspension height adjustment occurring during vehicle travel. 7, for a vehicle wherein the receptacle, load, or load carrier comprises a tank or boiler with leveling means extending between running gear and the tank or boiler.

30+, for a vehicle which is convertible from a wheeled vehicle to a nonvehicular structure.

43+, for a vehicle comprising a running gear and a wheel means, and means whereby the wheel means may be vertically adjusted relative to the running gear for the purpose of altering a dimension of the vehicle or a part thereof.

293+, for a velocipede which is provided with a prop or steadying device.

763.1+, for a vehicle which is provided with a retractable prop or stand which may be extended to stabilize the vehicle when not in motion.

180, Motor Vehicles,

39, and 41 for motor vehicles of that class (Class 180) with leveling means and subclasses 89.1+ for attaching bodies of motor vehicles of that class (Class 180) to the running gear thereof.

296, Land Vehicles: Bodies and Tops, appropriate subclasses for vehicle body construction in general, especially

35.1+, for devices securing the vehicle body to the running chassis frame including nominal recitation of running gear.

298, Land Vehicles: Dumping, appropriate subclasses for vehicles other than track or rail vehicles adapted to carry a load with means to manipulate the vehicle so that a considerable part of the load will move by gravity to unload the vehicle.
