Protective cover for a trailer hitch










Image Number 3 for United States Patent #4955968.

A cover for a trailer hitch, to prevent inadvertent injury to personnel when the hitch is not being used. An upstanding dome is provided for use with hitches of the type having a ball. The dome encircles the ball, and in addition provides a clearance space above the top of the ball, such that the cover can yield when jarred by the knee or leg of a person, thereby preventing injury. The cover has a base which is preferably oversize with respect to the dimensions of the hitch bar, and is provided with internal ribs or other cushioning structures that are yieldable. The ribs engage the surface of the bar such that when the cover is inadvertently bumped, the ribs yield, again preventing injury to the leg of a person. The cover also serves to protect parts of the hitch from corrosion.
