Abstract
Abstract A fifth wheel hitch is attached releasably to the bed of a pickup truck by brackets which resemble the parts of a swinging door hinge and which are connected by removable pins. The hinge-type brackets with the removable pins enable the hitch to be quickly and easily removed from and re-installed in the truck.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
280 words
A fifth wheel hitch adapted to be mounted in a bed of a pickup truck and adapted to be coupled releasably to a towed vehicle, said hitch comprising a pair of laterally spaced legs extending upwardly from said bed of said truck, said legs having upper and lower end portions, a supporting bar extending laterally between and fastened rigidly to the upper end portions of said legs, a coupler mounted on said supporting bar and adapted to be connected releasably to the tower vehicle, and means for releasably attaching said legs to said bed, said means comprising first brackets connected rigidly to the lower end portions of said legs, second brackets located adjacent said first brackets, each of said second brackets being connected rigidly to said bed and each including an outwardly projecting plate and an angle member with a vertical leg, hinge curls on said first and second brackets and extending longitudinally of said bed, said vertical leg abutting said hinge curls and extending substantially coextensively therewith, the curls on each first bracket and each adjacent second bracket interleaving with one another and forming a set of interleaved curls, each set of interleaved curls including two longitudinally spaced curls on one of said brackets and further including an intermediate curl on the other of said brackets and filling substantially all of the longitudinal space between said spaced curls, a pin extending through each set of interleaved curls to connect each first bracket releasably to the adjacent second bracket, and means holding each pin in the associated set of curls and selectively releasable to permit removal of said pin and thereby enable said hitch to be removed from said truck.
Claim 2
Dependent Claim
280 words
A fifth wheel hitch adapted to be mounted in a bed of a pickup truck and adapted to be coupled releasably to a towed vehicle, said hitch comprising a pair of laterally spaced legs extending upwardly from said bed of said truck, said legs having upper and lower end portions, a supporting bar extending laterally between and fastened rigidly to the upper end portions of said legs, a coupler mounted on said supporting bar and adapted to be connected releasably to the tower vehicle, and means for releasably attaching said legs to said bed, said means comprising first brackets connected rigidly to the lower end portions of said legs, second brackets located adjacent said first brackets, each of said second brackets being connected rigidly to said bed and each including an outwardly projecting plate and an angle member with a vertical leg, hinge curls on said first and second brackets and extending longitudinally of said bed, said vertical leg abutting said hinge curls and extending substantially coextensively therewith, the curls on each first bracket and each adjacent second bracket interleaving with one another and forming a set of interleaved curls, each set of interleaved curls including two longitudinally spaced curls on one of said brackets and further including an intermediate curl on the other of said brackets and filling substantially all of the longitudinal space between said spaced curls, a pin extending through each set of interleaved curls to connect each first bracket releasably to the adjacent second bracket, and means holding each pin in the associated set of curls and selectively releasable to permit removal of said pin and thereby enable said hitch to be removed from said truck.
Claim 3
Dependent Claim
79 words
A fifth wheel hitch as defined in claim 1 in which each of said second brackets includes a pair of longitudinally spaced curls formed on the outwardly projecting plate of the second bracket, each of said first brackets having a curl sized to fit between and interleave with the curls of the adjacent second bracket and where said angle member is L-shaped, is substantially coextensive with the interleaved hinge curls, and sandwiches said outwardly projecting plate to the bed.
Claim 4
Dependent Claim
100 words
A fifth wheel hitch as defined claim 4 in which said holding means comprise a radially extending hole in each of said pins and a hole in each of said second brackets, the hole in each pin being aligned with the hole in the adjacent bracket when said hitch is installed in said truck, and a locking member extending releasably into each pair of aligned holes to prevent removal of the associated pin from said curls and where said angle member is L-shaped, is substantially coextensive with the interleaved hinge curls, and sandwiches said outwardly projecting plate to the bed.
Claim 5
Dependent Claim
259 words
A fifth wheel hitch adapted to be mounted in a bed of a pickup truck and adapted to be coupled releasably to a towed vehicle, said hitch comprising a pair of laterally spaced legs extending upwardly from said bed of said truck, said legs having upper and lower end portions, a supporting bar extending laterally between and fastened rigidly to the upper end portions of said legs, a coupler mounted on said supporting bar and adapted to be connected releasably to the towed vehicle, and means for releasably attaching said legs to said bed, said means comprising first brackets connected rigidly to the lower end portions of said legs, second brackets located adjacent said first brackets, each of said second brackets being connected rigidly to said bed and each including an outwardly projecting plate and an angle member with a vertical leg, hinge curls on said first and second brackets and extending longitudinally of said bed, said vertical leg abutting said hinge curls and extending substantially coextensively therewith, the curls on each first bracket and each adjacent second bracket interleaving with one another and forming a set of interleaved curls, a pin extending through each set of interleaved curls to connect each first bracket releasably to the adjacent second bracket, and means normally holding each pin in the associated set of curls and selectively releasably to permit removal of said pin and thereby enable said hitch to be removed from said truck, said holding means normally preventing any substantial relative longitudinal movement between the curls of the associated set.
Claim 6
Dependent Claim
259 words
A fifth wheel hitch adapted to be mounted in a bed of a pickup truck and adapted to be coupled releasably to a towed vehicle, said hitch comprising a pair of laterally spaced legs extending upwardly from said bed of said truck, said legs having upper and lower end portions, a supporting bar extending laterally between and fastened rigidly to the upper end portions of said legs, a coupler mounted on said supporting bar and adapted to be connected releasably to the towed vehicle, and means for releasably attaching said legs to said bed, said means comprising first brackets connected rigidly to the lower end portions of said legs, second brackets located adjacent said first brackets, each of said second brackets being connected rigidly to said bed and each including an outwardly projecting plate and an angle member with a vertical leg, hinge curls on said first and second brackets and extending longitudinally of said bed, said vertical leg abutting said hinge curls and extending substantially coextensively therewith, the curls on each first bracket and each adjacent second bracket interleaving with one another and forming a set of interleaved curls, a pin extending through each set of interleaved curls to connect each first bracket releasably to the adjacent second bracket, and means normally holding each pin in the associated set of curls and selectively releasably to permit removal of said pin and thereby enable said hitch to be removed from said truck, said holding means normally preventing any substantial relative longitudinal movement between the curls of the associated set.
