Abstract

For use in combination along the transversely extending horizontal rear-end of a pickup truck or other overland vehicle, there is described an upright end-gate that is also alternatively employable as a ramp or as a trailer whenever panels of the end-gate are freed from their upright gating condition. In the upright gating condition, the multi-purpose end-gate includes: (A) an upright U-shaped frame member that is attachable to the vehicle rear-end; (B) an upright laminarly extending first-panel including a transversely extending trail-end removably pivotably attached along a first-pivot to the frame member and also a transversely extending lofty lead-end, and pivotably attached strut located within the laminar confines of the first-panel; (C) an upright laminarly extending second-panel including trailward-end extending along and pivotably connected to the first-panel lead end, and including below the trailward-end a leadward-end provided with drawbar-attachment capability; (D) capability for maintaining the two panels substantially coplanar whenever the end-gate is freed from gating condition and thereafter employed as a ramp or as a trailer; (E) wheels or other ground engagement carried at gating condition but thereafter employable at the strut when the end-gate is in the trailer mode.

For use in combination along the transversely extending horizontal rear-end of an overland vehicle, an upright end-gate that is also alternatively employable as a ramp or as a trailer whenever panels portions of the end-gate are freed from their up-right gating condition, said end-gate in the upright gating condition comprising:

(A) an upright U-shaped frame member at its external side extending along and being attachable along transversely extending frame-pivot means to said vehicle rear-end, said U-shaped frame member at its internal side having a transversely extending finite internal-width;
(B) an upright laminarly extending first-panel having a said finite internal-width and including a transversely extending trail-end that is removably pivotably attached along a first-pivot means to said frame member, said first-panel also having a transversely extending lead-end that loftily overlies said trail-end, and pivotably attached strut means located within the laminar confines of said first-panel;
(C) an upright laminarly extending second-panel locatable rearwardly of and substantially parallel to said first-panel, said second-panel having a transverse extent approximating that for said first-panel and including a trailward-end that is pivotably attached along a second-pivot means to the first panel lead-end, said second-panel also having a transversely extending leadward-end provided with drawbar-attachment means;
(D) inter-panels rigidifying means that is wholly inactive when the first-panel and second-panel are employed in up-right parallelism but that actively maintains the two panels substantially co-planar whenever the end-gate is pivoted at said second-pivot means and for alternative employments as ramp or trailer;
and
(E) terrain-traversing means removably attachable to said strut means whenever the end-gate panels are to be freed at said first-pivot means from said frame member and employed in a trailer mode.

In combination with the transversely extending rear-end of an overland vehicle, an upright dual-panels end-gate that is also alternatively employable as a ramp or as a trailer whenever panel portions of the end-gate are freed from their upright gating condition, said end-gate in the upright gating condition comprising:

(A) an upright U-shaped frame member at its external side extending along and being attached to said vehicle rear-end, said U-shaped frame member at its internal side having a transversely extending finite internal-width;
(B) an upright laminarly extending first-panel having a transversely extending trail-end that is removably pivotably attached along a first-pivot means to said frame member internal side, said first-panel also having a transversely extending lead-end that loftily overlies said trail-end;
(C) an upright laminarly extending second-panel located rearwardly of and substantially parallel to said first-panel, said second-panel having a transversely extending trailward-end that is pivotably attached along a second-pivot means to the first panel lead-end, said second-panel below the trailward-end thereof having a transversely extending leadward-end provided with drawbar-attachment means;
(D) pivotably attached strut means located within the laminar confines of said dual-panels end-gate, each said strut means being adapted to removably engage a terrain-traversing means;
(E) said terrain-traversing means being removably stowably attached to said dual-panels end-gate at locations remote from said strut means;
and
(F) inter-panels rigidifying means that is wholly inactive when the first-panel and second-panel are employed in up-right paralellism but that actively maintains the two panels substantially co-planar whenever the end-gate is pivoted at said second-pivot means and for alternative employments as ramp or trailer.
