摘要： An improved reciprocating dock for coupling and uncoupling a toy semitrailer and a toy tractor. The dock includes a reciprocable slide and a rotary cam arrangement. During an uncoupling operation, the slide is contacted and displaced by the semitrailer from a fully extended position to a retracted position. During this movement of the slide, the semitrailer travels over a roadway ramp which lifts the semitrailer, uncoupling the semitrailer from the tractor. A spring returns the slide from the fully retracted position to a partially extended position, and the rotary cam arrangement arrests the slide at the partially extended position. During movement of the slide to the partially extended position, the slide moves the semitrailer to a prescribed position such that the semitrailer remains elevated with respect to the tractor and poised for a re-coupling operation. To re-couple the semitrailer and tractor, the semitrailer displaces the slide from the partially extended position to the fully retracted position, and the spring then returns the slide from the fully retracted position, past the partially extended position, to the fully extended position. During this movement of the slide, the semitrailer moves past the ramp which causes the semitrailer to descend and reengage the tractor.
