Abstract
Abstract A framework for converting a ''''pick-up'''' truck into a variety of other utility vehicles is provided by the present invention. The invention also encompasses methods of loading and unloading the framework onto the vehicle. The framework is adapted to be coupled with a utility implement such as a wrecker rig, dump bed or other item. The framework is designed so as not to interfere with the normal cargo-carrying capacity of the truck bed once the framework is removed. The framework comprises a generally polygonal base frame having rollers along its leading edge to facilitate movement over the truck bed. First stanchion means comprising first and second spaced apart legs are disposed toward the forward end of the base frame and are pivotally coupled therewith. Each leg has a wheel disposed for surface engagement and when the vehicle moves against the legs they will pivot into their folded position on the truck bed. Second stanchion means comprising first and second spaced apart legs are located toward the opposite end of the frame from the first stanchion means. These legs are normally disposed in a vertical position to support the frame as they are rigidly coupled with it. The legs may be unlocked, however, to allow them to assume a position extending outwardly away from the frame to thereby lower it onto the truck bed. This occurs when the vehicle is moved in the direction opposite the second stanchion means. To unload the frame and support it on the two stanchion means the vehicle is moved in the direction opposite to which it is moved when loading the frame.

Claim 15
Independent Claim
219 words
A method of removing an implement-carrying frame from the bed of a truck-type vehicle and placing said frame on the vehicle-supporting surface, where the frame has a side extending transversely of the rear of the bed and said side comprises stanchion-receiving means, and stanchion means, each having a length greater than the distance from said stanchion-receiving means to said surface, said method comprising the steps of: coupling said stanchion means with said stanchion-receiving means, with said legs disposed at an acute angle relative to said surface and extending outwardly from said frame in the direction of said surface; moving said vehicle in the direction of said stanchion means whereby to cause the stanchion means to assume a vertical position and thereby lift the frame from the bed; locking said frame to said stanchion means after the latter are in their vertical positions; moving said vehicle in the opposite direction to which it first was moved to thereby pull said frame off of said bed; vertically supporting said frame at a point spaced from said stanchion means in the direction of said vehicle prior to the frame being completely pulled from the bed of the vehicle, whereby as the vehicle continues to move in said opposite direction said frame will be completely pulled from said bed and supported independently therefrom.
