发明名称 Trailer hitch assembly and method
摘要 A removable trailer hitch assembly for connecting a gooseneck trailer to a pickup truck is disclosed. The hitch assembly provides a base frame having a ball hitch mounted thereon and adapted to be positioned in the floor of the pickup truck box so the frame straddles both wheel wells and positions the ball hitch over the rear axle of the pickup truck. Two pairs of pivotable elongate members telescopingly attach to the base frame to frictionally engage the lower surface of the upper horizontal side rail caps of the pickup box. Biasing between and toward each side pair of side rail engaging members is provided to secure the hitch assembly in the pickup bed by making a positive frictional engagement with the box side rails. Upon the connection of the trailer to the hitch assembly the weight of the trailer and the fore and aft pull of the trailer further secure the hitch assembly to the pickup box. The hitch assembly is attached to the pickup box without the necessity for drilling, bolting or welding. A method of unhitching the trailer so as to leave the pickup box free and the hitch assembly attached to the trailer is also disclosed.
