Abstract
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.
