Abstract

Abstract A fifth wheel mounting structure for connecting a trailer such as a recreational vehicle and a pick-up truck having a bed thereon, in which a frame mounted on the bed has a fifth wheel platform thereon for receiving the fifth wheel pin extending downwardly from the forward end of the trailer. The frame is adjustable in height and in forward and rearward positions in the bed in order to properly distribute the weight on the wheels of the two vehicles and over the rear axle of the truck. The frame may include two downwardly extending vertically positioned legs having an adjustment means therein for varying the elevation of the fifth wheel, and may also contain a pair of spaced track means for receiving outwardly extending flanges on the respective legs and for rigidly securing the frame after an adjustment has been made longitudinally in the truck bed.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 107 words
A fifth wheel mounting structure for connecting a trailer and a pick-up truck having a bed with a bottom comprising a frame having a body and a generally vertical leg on each side connected to said body, means in each leg for adjusting the length thereof to vary the height of said body, a means for pivotally mounting a fifth wheel platform on said body on an axis transverse to the truck, and a multiple position means for securing each of said legs to the bottom of the bed of the truck and for adjusting the position of said frame forwardly and rearwardly in the truck bed.
Claim 2
Dependent Claim 107 words
A fifth wheel mounting structure for connecting a trailer and a pick-up truck having a bed with a bottom comprising a frame having a body and a generally vertical leg on each side connected to said body, means in each leg for adjusting the length thereof to vary the height of said body, a means for pivotally mounting a fifth wheel platform on said body on an axis transverse to the truck, and a multiple position means for securing each of said legs to the bottom of the bed of the truck and for adjusting the position of said frame forwardly and rearwardly in the truck bed.
Claim 3
Dependent Claim 60 words
A fifth wheel mounting structure as defined in claim 1 in which said multiple position means for securing each of said legs to the bottom of the bed of the truck includes a plate secured to the bottom of the truck bed, a track on said plate, and a locating pin disposed along said track for engaging the respective leg.
Claim 4
Dependent Claim 60 words
A fifth wheel mounting structure as defined in claim 2 in which each of said legs is provided with a laterally extending flange and each of said tracks includes a flange extending over said first mentioned flange and a screw extends through said last mentioned flanges and engaging said first mentioned flanges for holding said frame in an adjusted position.
Claim 5
Dependent Claim 63 words
A fifth wheel mounting structure as defined in claim 1 in which each of said legs consists of a downwardly extending member connected to the ends of said body, an L-shaped bracket connected to the respective member, and a bolt extending through holes in said bracket and in said respective members for securing the bracket to the respective member in an adjusted position.
Claim 6
Dependent Claim 59 words
A fifth wheel mounting structure as defined in claim 3 in which each of said legs consists of a downwardly extending member connected to the end of said body, an L-shaped bracket connected to the respective member, and a bolt extending through holes in said bracket and in said respective members for securing the bracket to the respective member.
Claim 7
Dependent Claim 73 words
A fifth wheel mounting structure as defined in claim 1 in which each of said legs includes two vertically arranged parts, and said means in each of said legs for adjusting the length thereof includes a series of vertically arranged holes in one of said parts, a hole in the other said parts, and a bolt extending through the holes in said parts to connect said parts rigidly together in an adjusted position.
Claim 8
Dependent Claim 73 words
A fifth wheel mounting structure as defined in claim 3 in which each of said legs includes two vertically arranged parts, and said means in each of said legs for adjusting the length thereof includes a series of vertically arranged holes in one of said parts, a hole in the other said parts, and a bolt extending through the holes in said parts to connect said parts rigidly together in an adjusted position.
Claim 9
Dependent Claim 64 words
A fifth wheel mounting structure as defined in claim 1 in which said means for pivotally mounting the fifth wheel platform on said body includes two upstanding members spaced laterally from one another, parts extending downwardly from said platform adjacent respective upstanding members, and pivot means extending through said upstanding members and the respective downwardly projecting member to connect said platform to said frame.
Claim 10
Dependent Claim 64 words
A fifth wheel mounting structure as defined in claim 6 in which said means for pivotally mounting the fifth wheel platform on said body includes two upstanding members spaced laterally from one another, parts extending downwardly from said platform adjacent respective upstanding members, and pivot means extending through said upstanding members and the respective downwardly projecting member to connect said platform to said frame.
