Patent attributes
A hitch-and-coupler assembly (130) couples a trailer vehicle to a towing vehicle. The hitch-and-coupler assembly (130) includes a hitch assembly (132) having a pitch hinge part (134) that defines at least one pinhole towards its trailing end about a pitch hinge axis (138). The hitch-and-coupler assembly also includes a coupler assembly (140) having a pitch hinge counterpart (142) defining at least one pinhole (144) towards its leading end. The pitch hinge counterpart (142) is detachably connectible to the pitch hinge part (134) by positioning the pitch hinge counterpart (142) into a check position in which the pin holes (136, 144) are aligned for passing a pitch hinge pin (26) there through. The hitch-and-coupler assembly (130) also includes a guiding arrangement (146) having a guiding surface (148) extending away from the check position toward a leading end of the hitch assembly (132). The pitch hinge counterpart (142) is operatively able to engage the guiding surface (148) and is displaceable along the guiding surface (148) towards the check position.
