A hinge bar connector assembly to connect spaced apart and separate ramps to a flat bed trailer of the type commonly known as a "hot shot" trailer of a semi-truck and trailer combination. Such trailers have spaced apart sockets or receiving channels around the peripheral edges of the trailer, including along both sides as well as along the front edge and the rear edge. The connector assembly in accordance with this invention has a first connecting member with two spaced apart legs to seat in a pair of adjacent receiving channels or sockets which support a pair of laterally spaced apart hinges and a removable hinge rod on which one end of a ramp having a connectable hinge member is pivotally connected. It also has a second identical connecting member seated in a pair of adjacent receiving channels or sockets which are spaced apart from the first connecting member to which a second ramp having a connectable hinge member is pivotally connected. The ramp members and their respective connecting members are spaced apart whatever distance desired for the items to be rolled up or down on said pair of ramp member for loading or unloading the trailer.

1. A ramp coupling assembly to couple a ramp to a short side edge portion of the bed of a cargo vehicle, comprising an elongated cross piece support member shorter than any side edge of said bed of said cargo vehicle detachable therefrom and detachable thereto, insert means extending from said support member laterally thereof and at a substantially right angle thereto to be received in socket means secured to said cargo vehicle, including said socket means secured to said cargo vehicle, ramp connecting means to connect said ramp to said support member, said laterally extending insert means and said ramp connecting means being spaced apart, and a receiving space between said insert means and said ramp connecting means to receive a portion of said socket means therein and to thereby enable said elongated cross piece support member to be more securely held by in turn enabling its insert means to be inserted farther into said socket means as said portion thereof is received into said receiving space between said insert means and said ramp connecting means, wherein said laterally extending insert means includes a first insert leg extending laterally from said support member at substantially a right angle thereto in one direction and terminating at a free end, a second insert leg extending laterally from said support member at substantially a right angle thereto in said one direction and terminating at a free end, said second insert leg being spaced apart from said first insert leg a pre-selected distance, said socket means including a first socket member having a cavity to receive said first insert leg, a second socket member having a cavity to receive said second insert leg, said second socket member being spaced apart from said first socket member said pre-selected distance, each of said cavities of said first and second socket members opening to a first peripheral edge of respective ones of said socket members bordering the respective entrances thereto, said free ends of said insert legs being insertable far enough for said support member to contact and rest against said first peripheral edge of each of said first and second socket members, wherein said support member comprises a cross piece having an inserted L-shaped cross-sectional configuration, including a first laterally elongated plate and a second laterally elongated plate integrally joined thereto extending at substantially a right angle therefrom, said first laterally elongated plate having an inner surface facing in one direction, said second laterally elongated plate having an inner surface facing in a direction which intersects said one direction and an outer surface facing in the opposite direction, said insert legs extending from said inner surface of said first laterally elongated plate and being spaced apart from said inner surface of said second laterally elongate plate to provide said receiving space between said insert legs and said inner surface of said second laterally elongated plate. 2. A ramp coupling assembly to couple a ramp to a short side edge portion of the bed of a cargo vehicle as set forth in claim 1, wherein said ramp connecting means includes a ramp connecting member positioned outwardly of said outer surface of said second laterally elongated plate and outwardly of said insert legs comprising said insert means. 3. A ramp coupling assembly to couple a ramp to a short side edge portion of the bed of a cargo vehicle as set forth in claim 1, wherein said ramp connecting means includes a ramp connecting assembly positioned outwardly of said outer surface of said second laterally elongated plate and outwardly of said insert legs comprising said insert means. 4. A ramp coupling assembly to couple a ramp to a short side edge portion of the bed of a cargo vehicle as set forth in claim 3, wherein said ramp connecting assembly includes a first ramp connecting member positioned outwardly of said outer surface of said second laterally elongated plate and a second ramp connecting member on said ramp, said second ramp connecting member being connectable to said first ramp connecting member. 5. A ramp coupling assembly to couple a ramp to a short side edge portion of the bed of a cargo vehicle as set forth in claim 3, wherein said ramp connecting assembly includes a pair of spaced apart hinge members to pivotally receive an elongated hinge bar, including said elongated hinge bar, said elongated hinge bar comprising an elongated shank and a handle extending from said shank at substantially a right angle, a handle receiving recess positioned outwardly of said second laterally elongated plate and in registration with said handle to receive said handle therein when said elongated hinge bar is received by said spaced apart hinge members and pivoted to rotate said handle into said receiving recess to thereby hold said hinge bar from lateral movement relative to said spaced apart hinge members, and a hinge member on said ramp to pivotally engage said hinge bar for pivotal movement thereon between said pair of spaced apart hinge members.
