Abstract

Abstract A hoist frame comprises a planar member having front and rear opposite ends and top and bottom planar surfaces and a pair of extending members comprising a pair of spaced parallel members extending from the bottom surface at the rear end of the planar member perpendicular to the bottom surface. Mounting means pivotally mounts the planar member of the hoist frame to the chassis frame at the bottom surface at the front end of the planar member in a manner whereby the extending members extend beyond and to an area beneath the chassis frame. A jack is affixed to the planar member of the hoist frame at the bottom surface at the rear end thereof equidistantly from the extending members and extending perpendicularly from the bottom surface for pivotally moving the hoist frame about the mounting means thereof. A pair of boom securing means extend perpendicularly from the top surface of the planar member in the areas of the front and rear end of the planar member for selectively releasably securing a variable length boom at one of the boom securing means or both of the boom securing means.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 199 words
A fifth wheel carrier hoist for a towing vehicle for towing heavy vehicles, said towing vehicle having a chassis frame, said carrier hoist comprising a hoist frame comprising a substantially planar member having front and rear opposite ends and top and bottom substantially planar surfaces and a pair of extending members comprising a pair of spaced substantially parallel members extending from the bottom surface at the rear end of the planar member substantially perpendicular to said bottom surface, each of the pair of extending members having holes formed therethrough for accommodating pin means adapted to be removably inserted via selected holes thereof supporting a boom via each of said extending members; mounting means pivotally mounting the planar member of the hoist frame to the chassis frame at the bottom surface at the front end of said planar member is a manner whereby the extending members extend beyond and to an area beneath said chassis frame; jack means affixed to the planar member of the hoist frame at the bottom surface at the rear end thereof substantially equidistantly from the extending members and extending perpendicularly from said bottom surface for pivotally moving the hoist frame about the mounting means thereof;
Claim 2
Dependent Claim 199 words
A fifth wheel carrier hoist for a towing vehicle for towing heavy vehicles, said towing vehicle having a chassis frame, said carrier hoist comprising a hoist frame comprising a substantially planar member having front and rear opposite ends and top and bottom substantially planar surfaces and a pair of extending members comprising a pair of spaced substantially parallel members extending from the bottom surface at the rear end of the planar member substantially perpendicular to said bottom surface, each of the pair of extending members having holes formed therethrough for accommodating pin means adapted to be removably inserted via selected holes thereof supporting a boom via each of said extending members; mounting means pivotally mounting the planar member of the hoist frame to the chassis frame at the bottom surface at the front end of said planar member is a manner whereby the extending members extend beyond and to an area beneath said chassis frame; jack means affixed to the planar member of the hoist frame at the bottom surface at the rear end thereof substantially equidistantly from the extending members and extending perpendicularly from said bottom surface for pivotally moving the hoist frame about the mounting means thereof;
Claim 3
Dependent Claim 103 words
a variable length boom; and a pair of boom securing means extending substantially perpendicularly from the top surface of the planar member in the areas of the front and rear ends of said planar member for selectively releasably securing the boom at one of the boom securing means or both of said boom securing means, each of the pair of boom securing means comprising a pair of spaced substantially parallel plates straddling the boom and having holes formed therethrough, and pin means adapted to be removably inserted via selected holes of the pair of spaced plates thereby restraining said boom between said plates.
Claim 4
Dependent Claim 103 words
a variable length boom; and a pair of boom securing means extending substantially perpendicularly from the top surface of the planar member in the areas of the front and rear ends of said planar member for selectively releasably securing the boom at one of the boom securing means or both of said boom securing means, each of the pair of boom securing means comprising a pair of spaced substantially parallel plates straddling the boom and having holes formed therethrough, and pin means adapted to be removably inserted via selected holes of the pair of spaced plates thereby restraining said boom between said plates.
