Abstract:
1. A swinging cargo ramp assembly integrated within a rear end of a cargo bed of a trailer or vehicle providing a pair of pivotally attached adjustable cargo ramps independently movable from a stored side panel position to an angled ramp position at said rear end of said cargo bed, said swinging cargo ramp assembly having two independent sets of component segments, each said component set comprising: a rear trailer tab base defining an upper surface and a tab edge horizontally secured to a rear side frame of said cargo bed, a static vertical support member defining a cylindrical vertical shaft having a lower end secured to said upper surface of said tab base and an upper end, and an upper shaft cap, a horizontal pivot member defining an upright cylindrical collar with a vertical bore pivotally installing upon said vertical shaft of said vertical support member, said upright cylindrical collar further defining an outer surface from which a first end of a cylindrical lateral pivot extension depends, said lateral pivot extension having an end cap, a vertical pivot member defining a cylindrical extension collar with a horizontal bore pivotally engaging said lateral pivot extension of said horizontal pivot member between said end cap and said upright cylindrical collar, said extension collar further defining an outer surface to which a lower end of a cylindrical ramp shaft extension is attached, said ramp shaft extension terminating an upper end, a rear axial slide rail member providing a base section attached to said rear end of said cargo bed below a floor of said cargo bed and an upright flange, and a ramp section providing a rigid angled platform with static support during loading and unloading from said cargo bed, said ramp section defining an upper ramp surface, a distal end and a proximal end further defining a cylindrical ramp collar having an outer surface and a ramp collar bore, said ramp collar bore slidably and pivotally installed upon said ramp shaft extension of said vertical pivot member, said ramp collar attaching a ramp extension base of a linear ramp extension, said ramp extension further forming a ramp slide rail claw which will engage said upright flange of said axial slide rail member when said ramps are placed into said angled ramp position behind said cargo bed.
