DEFINITION

Classification: 414/387

Means comprises device or structure for cooperating with motion of vehicle to initiate relocation of body component (e.g.,., floor or floor section, gate, etc.) thereof:

(under subclass 376) Apparatus wherein the vehicle is in motion and the means comprises a device or structure which, as a result of the vehicle's movement relative thereto, causes one or more movable components of the vehicle's body to be repositioned relative to the remainder of the body in such a manner as to provide an exit for part or all of the load of the vehicle, or, in the alternative, releases a latching mechanism for enabling the component to be repositioned by the force of gravity acting on either the component or the load, or on both.

(1) Note. It is not necessary that the motion of the vehicle continue for the duration of the movement of its load therefrom.

(2) Note. The means of this subclass may serve also to return the component (or components) to its nonload-exiting position; in fact, in the absence of a more appropriate locus, patents limited to claiming means for performing only this operation are classified here.
