ABSTRACT:
A coupling mechanism adapted for attaching a draft vehicle to a drawn vehicle, so as to permit relative pivotal movement therebetween in a generally horizontal plane, and comprising an arcuate orientation of abutment means adapted to be supported by the draft vehicle and another abutment means adapted to be supported by the drawn vehicle, with at least one of the abutment means being selectively expandible or extendible by power means, for causing interlocking coaction between the first and second mentioned abutment means, so as to transmit force from the first mentioned abutment means to the second mentioned abutment means in a direction generally laterally of the longitudinal axis of the mechanism, whereby the drawn vehicle during a backing-up operation moves in the same general direction as the draft vehicle. The mechanism is useable with a fifth wheel type of truck-trailer combination as well as with trailer hitch drawn-bar type couplings for use in connection with automotive and truck-type vehicles.
