Abstract: An above-bed structure having two or more feet is attached into a bed of a truck using inserts which can be removed or retracted to provide a flat, unobstructed truck bed. Each insert includes an above-bed cleat portion and a below-bed peg portion which is received in a below-bed socket. Each insert is received first vertically without substantial rotation into its socket and then by rotation to a terminal point wherein the insert is vertically held by the socket. The above bed structure is then placed onto the inserts such that the feet mate with the inserts to prevent the inserts from rotating away from their terminal point, thus preventing the inserts from being removed from their sockets. The attachment can be completed by inserting mounting pins into aligned holes on the cleat portions and the feet. In one embodiment, the feet are supported on a bed place section of the insert which is offset from the rotational axis of the insert.

Abstract: A bearing guide for a hitch allows lateral movement of the hitch. The bearing guide is elevated relative to the bearing surface. Two trucks roll on wheels each about their own elevated guide for fore-and-aft rolling of the hitch point. The bearing guide also provides a keyway which receives a locking key. The locking key is supported on both sides of the keyway by a plunger control rod, and can be unlocked by pulling and rotating a handle. When the towing vehicle is driven to relocate the hitch point, the locking key reengages itself into a different keyway on the bearing guide.

Abstract: A hitch includes a control linkage having a single handle on a control bar. The control linkage doubles to provide both a positive safety feature and a movement feature to the hitch, permitting single handed operation of both the positive safety feature and the opening of the hitch with the single handle. A release throw of four inches or less opens jaws of the hitch. A latch is included which can secure the control bar in either a secured position or in a release position. A follower is secured to one of the jaws to maintain timing between the jaws, and the follower doubles as a hitch position indicator so an operator to easily visually discern the position of the hitch. By including kingpin recesses of appropriate location and depth on the jaws, the hitch can be used with or without a lube plate over the skid plate.
