Abstract:

PURPOSE: To allow a semi-automatic connecting work by operating one tow bar for vertical oscillation, coupling a peg on the upper surface at the base end of another tow bar to a coupling hole on the end of the oscillating bar for linear traction with a towing tractor, and linearly connecting a knuckled steering member on the front end of a trailer.
CONSTITUTION: Tow bars 12 and 14 connected to the rear sides of front and rear trailers, the rear sides of front wheel knuckled steering members 11 and 10 and a front end bearing member 16 via pivotal pins 18 are resiliently supported in an approximately horizontal posture under the contact of the stopper rods 13d and 15d of spring type stoppers 13 and 15 with engagement pieces 19 projected from the underside of tow bar base ends. A peg at one side of the bars 12 and 14 is coupled to an engagement hole 21 at the other side. Also, the ends of the bars 12 and 14 at one side are positioned and held at a center with a stopper 25 having a slope at the other side. and connected to the pieces 19 via coil springs 29. In addition, the ends are superposed down and a key member 26 is kept faced to the end of the engagement piece 19 positioned at one side with the stopper 25. According to this construction, a connecting work becomes semi-automatic, thereby allowing an easy work and enhancing both workability and safety.
