An integrated group of mechanical aids and a method related to the coupling and the uncoupling of a towed vehicle of the well-known tongue-loaded, weight-transfer type, which aids and method permit the uncoupling of the towed vehicle from a prime mover while allowing all components of the coupling assembly to remain in place and attached to the towed vehicle all positioned for subsequent recoupling.

A detachable base-plate assembly providing a means for support to the tongue of a towed vehicle of a tongue-loaded, weight-transfer type during standing, coupling, and uncoupling operations, said base-plate assembly comprising: a base plate defining a generally flat ground-contactable undersurface and an upper surface; a pair of rail-like projections disposed directionally parallel each to the other across and normal the base plate upper surface, said pair providing a pathway across the base plate upper surface for a rotatable wheel mounted on an axle of a wheel-axle unit, the paired rail-like projections extending normally from the base plate upper surface and each rail-like projection including a longitudinal slot for limiting movement of one of the two ends of said axle; an elongated member for bridging a space intervening the base plate upper surface and a tongue jack of the towed vehicle, the axle unit being yoke-linked via said axle to said elongated member, the lower end of said elongated member being proximal the upper surface of the base plate, the upper end of the elongated member being distal to the base plate upper surface such that said upper end can be selectively positioned to detachably mate with the towed vehicle tongue jack; elastic travel restraints for the wheel-axle unit, comprising two matched pairs of juxtaposed counteracting elastic members, each elastic member secured at one end to the wheel-axle unit, the other end of each elastic member secured to the upper surface of the base plate, the pairs balanced tensionally to maintain a normally central position for the wheel-axle unit and elongated member on the upper surface of the base plate; and a lever proximal the wheel-axle unit providing a means for manually rotating the wheel and axle unit.
