Abstract
Abstract A camper loading apparatus wherein a direct drive pinion assembly releasably affixed to the rear of a transportable bed engages corresponding racks on a camping unit. The pinion assembly becomes locked to both the transportable bed and the camper when the camper is fully loaded onto the bed. Each of the loading pinions may be selectively rotated individually or in unison to accomplish the loading operation. The invention provides supporting structure for the camper while remaining detachable thereby allowing the transportable bed to be used for other purposes without cumbersome or interfering structure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
76 words
A camper loading and securing system comprising: a transportable bed; two pinion housings attached to the transportable bed at spaced side-by-side locations; a rack-engaging pinion mounted for rotation upon its axis within each housing, each pinion comprising means accommodating independent unlimited rotation thereof in both forward and reverse directions and at least one mechanical power coupling which is actable directly upon the axis to rotate each pinion; and means selectively connecting the pinions for unitary movement.
Claim 2
Dependent Claim
76 words
A camper loading and securing system comprising: a transportable bed; two pinion housings attached to the transportable bed at spaced side-by-side locations; a rack-engaging pinion mounted for rotation upon its axis within each housing, each pinion comprising means accommodating independent unlimited rotation thereof in both forward and reverse directions and at least one mechanical power coupling which is actable directly upon the axis to rotate each pinion; and means selectively connecting the pinions for unitary movement.
Claim 3
Dependent Claim
118 words
A camper loading and securing system comprising: a transportable bed; two pinion housings attached to the transportable bed at spaced side-by-side locations; a unitary frame joining the pinion housings and having spaced apertures adapted to be superimposed over corresponding retainers in the transportable bed such that the pinion housings and frame are easily removable from The transportable bed by lifting the frame from the retainers; a rack-engaging pinion mounted for rotation upon its axis within each housing, each pinion comprising means accommodating independent rotation thereof in both forward and reverse directions and at least one mechanical power coupling which is actable directly upon the axis to rotate each pinion; and means selectively connecting the pinions for unitary movement.
Claim 4
Dependent Claim
118 words
A camper loading and securing system comprising: a transportable bed; two pinion housings attached to the transportable bed at spaced side-by-side locations; a unitary frame joining the pinion housings and having spaced apertures adapted to be superimposed over corresponding retainers in the transportable bed such that the pinion housings and frame are easily removable from The transportable bed by lifting the frame from the retainers; a rack-engaging pinion mounted for rotation upon its axis within each housing, each pinion comprising means accommodating independent rotation thereof in both forward and reverse directions and at least one mechanical power coupling which is actable directly upon the axis to rotate each pinion; and means selectively connecting the pinions for unitary movement.
Claim 5
Dependent Claim
16 words
A system as defined in claim 2 wherein each pinion housing presents an upwardly directed tab.
Claim 6
Dependent Claim
43 words
A system as defined in claim 1 wherein said selectively connecting means is a coupling shaft coaxial with the pinions and displaceable from a first position accommodating independent unlimited rotation of each pinion to a second position accommodating joint rotation of the pinions.
