Description
HITCH DRAWBAR STORAGE APPARATUS
This invention is in the field of hitches for connecting a trailer or like towed vehicle to a towing vehicle, and in particular an apparatus for storing hitch tubes.
BACKGROUND
Connecting hitch mechanisms for trailers take a variety of forms, such as clevis and tongue mechanisms, ball and socket mechanisms, pintle hook and ring mechanisms, and the like. In order to accommodate the different types of mechanisms it has become common to mount a tube bracket to the frame of the towing vehicle. A receiver tube is fixed to the tube bracket and defines a rectangular socket and allows an operator to insert and secure different rearward extending hitch drawbars that correspond to a variety of trailer hitches, thus facilitating towing a variety of trailers. The hitch drawbar can also be readily removed when not on use reducing the risk that a person will walk or drive into the drawbar.
Because these drawbars present somewhat of a hazard, in many jurisdictions it is illegal to leave the hitch drawbar in the socket on the towing vehicle, and so it is necessary to remove the drawbar and store it until the next time it is needed. Also it is common to have two different drawbars to accommodate two different trailers. Placing the drawbar loose in the truck box is inconvenient as they slide around the box and can interfere with loading the box. They can also be quite heavy and so present a hazard when the truck stops, starts, or turns suddenly sending the drawbar across the floor of the box.
United States Patent Number 8,893,939 to Brass discloses a receiver tube mounted on a trailer where the drawbar is removed from the towing vehicle and stored with the trailer.
This kind of storage is suitable where the towing vehicle is used to pull only a single trailer.
United States Patent Numbers 7,815,211 to Witchey, 6,527,292 to Adair, and 6,866,285 to Stamp disclose storage for a drawbar on the tube bracket, where the drawbar extends laterally in a storage position and rearward when in an operating position.
United States Patent Number 8,231,035 to Michael discloses a receiver tube mounted to the inside of a truck box to store a drawbar.
For storage on the towing vehicle of two drawbars United States Patent Number 5,476,279 to Klemetsen discloses a laterally oriented receiver bracket which defines openings in each end thereof to store a drawbar extending laterally in each end. United States Published Patent Application Number 20080264991 of Foster discloses a pair of receiver tubes mounted in a tray that is bolted to holes drilled in the floor of a truck box.
Light trucks or pick-up trucks, such as the Ford lm F150, Chevrolet SilveradoTM, Dodge Ram', and so forth, are commonly used for towing trailers. The boxes on these pick-up trucks are similar in that the steel floor of the boxes define grooves along their length from front to back, there is a rib extending down from the top inside edge of the box, and wheel wells extend up from the floor on each side of the box. The tray of Foster is bolted to the floor of such a pick-up truck near one side of the box just behind the wheel well where it is convenient to access the drawbars stored therein.
