Folding gate ramp for pickup trucks

Claim 1

An apparatus for use as a combined tailgate and loading ramp for a pickup truck of the type having a bed, sidewalls adjacent the bed, and a removable tailgate adjacent the bed, said apparatus comprising: a rectangular inner panel; a rectangular outer panel generally congruent with said inner panel; a knockdown hinge between said inner panel and said outer panel for folding of said inner and outer panels along respective commonly aligned panel hinge edges, said folding being between an extended planar disposition for ramp use and a juxtaposed sandwich position for gate use; said hinge being configured to separate said inner and outer panels when in a vertical closed gate position between said sidewalls; mounting means for pivotally mounting said inner panel to the bed of the truck at a rear edge of the bed to replace the removable tailgate, said mounting means enabling said inner panel to rotate about an axis parallel to an outer edge of said inner panel, said axis being adjacent and parallel to said rear edge; latching means for releasably holding said inner panel in said vertical closed gate position between the sidewalls; clamping means for releasably holding the panels together in said sandwich position; means for preventing said inner panel from rotating, in a sense of rotation away from said sandwich position toward said planar disposition, beyond said planar disposition; and said means for preventing said inner panel from rotating beyond said planar disposition includes plates fixed to one of the panels, said plates bearing against the other one of the panels when the panels are disposed in said planar disposition; whereby the removable tailgate may be removed, said apparatus may be mounted to the truck in place thereof, and said apparatus may be either extended to the ground for use as a ramp or folded for use as a gate.

Claim 2

An apparatus for use as a combined tailgate and loading ramp for a pickup truck of the type having a bed, sidewalls adjacent the bed, and a removable tailgate adjacent the bed, said apparatus comprising: a rectangular inner panel; a rectangular outer panel generally congruent with said inner panel; a knockdown hinge between said inner panel and said outer panel for folding of said inner and outer panels along respective commonly aligned panel hinge edges, said folding being between an extended planar disposition for ramp use and a juxtaposed sandwich position for gate use; said hinge being configured to separate said inner and outer panels when in a vertical closed gate position between said sidewalls; mounting means for pivotally mounting said inner panel to the bed of the truck at a rear edge of the bed to replace the removable tailgate, said mounting means enabling said inner panel to rotate about an axis parallel to an outer edge of said inner panel, said axis being adjacent and parallel to said rear edge; latching means for releasably holding said inner panel in said vertical closed gate position between the sidewalls; clamping means for releasably holding the panels together in said sandwich position; means for preventing said inner panel from rotating, in a sense of rotation away from said sandwich position toward said planar disposition, beyond said planar disposition; and said means for preventing said inner panel from rotating beyond said planar disposition includes plates fixed to one of the panels, said plates bearing against the other one of the panels when the panels are disposed in said planar disposition; whereby the removable tailgate may be removed, said apparatus may be mounted to the truck in place thereof, and said apparatus may be either extended to the ground for use as a ramp or folded for use as a gate.

Claim 3

An apparatus for use as a combined tailgate and loading ramp for a pickup truck of the type having a bed, sidewalls adjacent the bed, and a removable tailgate adjacent the bed, said apparatus comprising: a rectangular inner panel; a rectangular outer panel generally congruent with said inner panel; a knockdown hinge between said inner panel and said outer panel for folding of said inner and outer panels along respective commonly aligned panel hinge edges, said folding being between an extended planar disposition for ramp use and a juxtaposed sandwich position for gate use; said hinge being configured to separate said inner and outer panels when in a vertical closed gate position between said sidewalls; mounting means for pivotally mounting said inner panel to the bed of the truck at a rear edge of the bed to replace the removable tailgate, said mounting means enabling said inner panel to rotate about an axis parallel to an outer edge of said inner panel, said axis being adjacent and parallel to said rear edge; latching means for releasably holding said inner panel in said vertical closed gate position between the sidewalls; and clamping means for releasably holding the panels together in said sandwich position; said latching means includes a cable transversely running across said inner panel, said cable activating latches to release said inner panel from said vertical closed gate position, and a hand access hole in said outer panel for pulling said cable to release said latches, said access hole disposed adjacent said cable when the panels are in said sandwich position; whereby the removable tailgate may be removed, said apparatus may be mounted to the truck in place thereof, and said apparatus may be either extended to the ground for use as a ramp or folded for use as a gate.

Claim 4

An apparatus for use as a combined tailgate and loading ramp for a pickup truck of the type having a bed, sidewalls adjacent the bed, and a removable tailgate adjacent the bed, said apparatus comprising: a rectangular inner panel; a rectangular outer panel generally congruent with said inner panel; a knockdown hinge between said inner panel and said outer panel for folding of said inner and outer panels along respective commonly aligned panel hinge edges, said folding being between an extended planar disposition for ramp use and a juxtaposed sandwich position for gate use; said hinge being configured to separate said inner and outer panels when in a vertical closed gate position between said sidewalls; mounting means for pivotally mounting said inner panel to the bed of the truck at a rear edge of the bed to replace the removable tailgate, said mounting means enabling said inner panel to rotate about an axis parallel to an outer edge of said inner panel, said axis being adjacent and parallel to said rear edge; latching means for releasably holding said inner panel in said vertical closed gate position between the sidewalls; and clamping means for releasably holding the panels together in said sandwich position; said latching means includes a cable transversely running across said inner panel, said cable activating latches to release said inner panel from said vertical closed gate position, and a hand access hole in said outer panel for pulling said cable to release said latches, said access hole disposed adjacent said cable when the panels are in said sandwich position; whereby the removable tailgate may be removed, said apparatus may be mounted to the truck in place thereof, and said apparatus may be either extended to the ground for use as a ramp or folded for use as a gate.
