DEFINITION

Classification: 414/469

With load-receiving portion, or significant section thereof, pivotable relative to horizontal:

(under subclass 467) Apparatus wherein the handling means comprises enabling the load-receiving portion, or at least a significant part of the portion, to move in an arcuate path relative to a generally horizontal plane, and thus impart a change in the attitude of the portion relative to that plane, for facilitating the loading or unloading of the vehicle.

(1) Note. This and the indented subclasses constitute, principally, a reclassification of subclasses 501 and 505-511 of former Class 214 (subclasses 502-504 of that class, now subclasses 471-473, having been left as they were, except for being screened for conflicting subject matter). While the art of the 501 and 505-511 area consistently included a load-receiving portion pivotable about a horizontal axis, as required by former subclass 501, it occasionally lacked the "handling means" of its outdent, former subclass 500, now subclass 467. Accordingly, in order to avoid a significant redistribution of the subclasses 501+ art, this subclass (469) has been defined in such a manner as to identify the pivoting of the load-receiving portion as constituting the handling means. In addition, certain of the subclasses indented hereunder were established in order to provide for specific types of devices which conventionally are construed to be "handling means".

(2) Note. "Load-receiving portion", as used herein, denotes the one or more elements, members, etc., of a vehicle which supports a load during transit, as distinguished from an element, etc., which supports a load only during the loading or unloading of the vehicle.

(3) Note. "Generally horizontal plane" usually is descriptive of the surface from or to which a load moves to or from the vehicle.

SEE OR SEARCH THIS CLASS, SUBCLASS:

349+, 354+ and 373+, for the combination of a vehicle, or portion thereof, and means external of the vehicle for changing the attitude of the vehicle, or portion, for a vehicle loading or unloading purpose.

495+, for a vehicle having a raisable or lowerable load-receiving portion and wherein, but only for the purpose of facilitating its movement to or from an elevated position, the portion may undergo pivotable movement of the kind provided for in this subclass (469). 545, and 556+, for a self-loading or unloading vehicle having other loading or unloading means, which means may be, in the former subclass, a vertically rectilinearly movable component of the load-receiving portion, or, in the latter subclass, a curvilinearly movable component of the load-receiving portion; also, see the latter subclass (556) for an explanation of the relationship between the art of that subclass and the art of this subclass (469).

575+, for an external means subcombination of the type of combination described in the search note above to subclasses 349+, 354+ and 373+.

629, 631+, 641+, and 663+, for a portable (e.g.,., vehicle-mounted) elevator or hoist having a load carrier which is movable relative to the vehicle, which movement may include pivoting about a more or less horizontal axis.

37, Excavating,

412+, for an excavating device in the nature of a scoop which is provided with ground engaging wheels and wherein the scoop may be mounted for moving pivotably about a horizontal axis for acquiring, or relieving itself of, a load.

298, Land Vehicles: Dumping, appropriate subclasses for a vehicle of the kind proper for that class which is so constructed that, by manipulation of the vehicle or a portion thereof, a load will move by gravity from the vehicle. It is not possible to state, at the time of this reclassification, a definitive line between Class 298 subject matter, on the one hand, and some of the art which appears in certain of the subclasses of this area, particularly in this subclass (469), on the other hand.
