Abstract

Abstract A vehicle tow bar comprises a longitudinally extending, tubular cross bar mounted laterally across the front of the vehicle to be towed, the cross bar mounting for longitudinal movement thereon, pivotal rotation thereabout, and laterally pivotal movement relative thereto, a longitudinally extensible, two section telescoping reach having a hitch coupler mounted on its forwardmost end arranged for connection to an associated hitch ball component on a tow vehicle. A pair of tow chains connect opposite longitudinal ends of the cross bar to the forwardmost end of the reach and are arranged to become taut when the reach is extended to a desired maximum length. A locking screw on the rear section of the reach releasably engages the forward section of the reach to move the latter forwardly in order to tension the chains attached thereto and to prevent inward collapsing of the telescoping sections. When not in use, the reach may be pivoted on the cross bar to a collapsed position whereby it overlies the cross bar and is locked thereon. A chain tray is provided to hold the chains while the assembly is in collapsed, storage position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 138 words
For attachment to a vehicle to be towed, a vehicle tow bar, comprising: (a) an elongated cross bar member configured for attachment to the front end of a vehicle to be towed and arranged to extend laterally across the front end thereof, (b) a forwardly projecting reach mounted at its rear end centrally to the laterally extending cross bar, the reach comprising at least two longitudinally telescoping sections, the reach mounting at its forward end a coupler component of a trailer hitch, (c) flexible tow line means connecting the forward end portion of the reach to the opposite ends of the laterally extending cross bar member, and (d) securing means engaging the telescoping sections of the reach to releasably lock the sections in fully extended condition for releasably tensioning the flexible tow line means in taut, towing condition.
Claim 2
Dependent Claim 138 words
For attachment to a vehicle to be towed, a vehicle tow bar, comprising: (a) an elongated cross bar member configured for attachment to the front end of a vehicle to be towed and arranged to extend laterally across the front end thereof, (b) a forwardly projecting reach mounted at its rear end centrally to the laterally extending cross bar, the reach comprising at least two longitudinally telescoping sections, the reach mounting at its forward end a coupler component of a trailer hitch, (c) flexible tow line means connecting the forward end portion of the reach to the opposite ends of the laterally extending cross bar member, and (d) securing means engaging the telescoping sections of the reach to releasably lock the sections in fully extended condition for releasably tensioning the flexible tow line means in taut, towing condition.
Claim 3
Dependent Claim 39 words
The vehicle tow bar of claim 1 wherein said securing means comprises a screw on one of said telescoping sections arranged to releasably engage and extend the other of said telescoping sections to tension the flexible tow line means.
Claim 4
Dependent Claim 75 words
The vehicle tow bar of claim 2 wherein said one telescoping section is hollow and receives the other section telescopically within it, and the securing means includes a nut on the one section rearwardly of the forward terminal end thereof, the nut receiving the screw arranged to extend through an opening in the wall of the one telescoping section and abut the other said telescoping section when the latter is in substantially fully extended position.
Claim 5
Dependent Claim 44 words
The vehicle tow bar of claim 1 wherein the laterally extending cross bar member is tubular in configuration and the telescopic reach is mounted on the cross bar member for axial rotation thereabout, for upward and downward pivotal movement of the forwardly telescoping reach.
Claim 6
Dependent Claim 37 words
The vehicle tow bar of claim 4 wherein the telescoping reach is further mounted on the laterally extending cross bar by pivot means arranged to permit lateral swinging movement of the reach relative to the cross bar.
Claim 7
Dependent Claim 58 words
The vehicle tow bar of claim 5 wherein the reach is further mounted to the cross bar by mounting bracket means arranged on the laterally extending cross bar for sliding movement thereon, and locking means engages said cross bar and said mounting bracket to releasably secure said mounting bracket in various laterally disposed positions on the cross bar.
Claim 8
Dependent Claim 54 words
The vehicle tow bar of claim 6 wherein the reach is pivotal to a storage position in which the reach is disposed in collapsed condition adjacent and parallel to the cross bar member, and locking means engages the cross bar member and said mounting bracket to releasably secure the reach in said storage condition.
