摘要: A decorative and protective cover for covering the end of a towing hitch tube which is exposed when the drawbar that is used for towing a trailer is removed from the hitch tube. The cover is a one-piece molded plastic part that has a covering portion comprising an end wall that is disposed in end covering relation to the end of the hitch tube and an integral attaching portion that projects from a central region of the cover end wall for releasably attaching the cover to the hitch tube. The cover further includes a top wall and side walls that are in top and lateral covering relation to the hitch tube. It also has a partial bottom wall that is an underlying relation to the hitch tube but contains a centrally located notch that provides access to the attaching portion for unlatching the attaching portion from the hitch tube when it is desired to remove the cover. The attaching portion comprises a tubular wall fitting closely into the hitch tube and an integral catch that snaps into a hole in the hitch tube which is used for pinning the drawbar to the hitch tube when the drawbar is in use. The cover also contains covering provisions for covering safety chain attachment holes that are provided to either side of the hitch tube. Advantageously the cover is fabricated as an injection molded plastic part from a tough, durable plastic such as polypropylene.

摘要: A gooseneck hitch assembly mounted in the load bed of a pick-up truck. The hitch assembly includes a housing mounted in the bed of the truck, and a hitch ball removably mounted in the housing. The housing includes a spring biased cylindrical locking pin for positively locking together the housing and hitch ball against separation. The cylindrical pin is manually movable to either a locking position wherein the hitch ball is locked in the housing or to an unlocked position whereby the hitch ball can be readily removed from the housing.
