ABSTRACT:
A device (10) that facilitates the coupling of a socket-type coupling (34) of a trailer to a vehicle (12) that tows the trailer. The device (10) enables a single unaided individual to back a vehicle equipped with a hitch ball (30) into a socket-type coupling (34) of a trailer. The device (10) includes a substantially "V"-shaped ramp (14) inclined about the hitch ball (30) that, upon the backing of the vehicle, guides the socket coupling (34) of the trailer to a trigger position above the hitch ball (30). When it reaches such trigger position, the socket coupling (34) impacts an abutment (20) to pivot a support member (24) from its supporting position to a release position, to allow the ramp member (14) to drop down below the hitch ball (30) and allow the socket coupling to drop onto the hitch ball (30).
