Abstract

Abstract A trailer hitch bar carrying a hitch member at its rearward end and carried for fore-and-aft sliding movement in a sleeve fixable to the towing vehicle, the bar normally being retained fixedly in the sleeve by a latch, but being extendable rearwardly from said sleeve and horizontally pivotable when so extended for greater ease of registry with the hitch member of the towed vehicle, the bar being self-aligning with the sleeve so as to be re-engaged in the sleeve by backing movement of the towing vehicle after the hitch members are engaged.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 255 words
A trailer hitch bar device comprising: a. a sleeve member adapted to be affixed to a towing vehicle to extend generally parallel to the direction of vehicle travel and opening rearwardly, b. a hitch bar normally coaxial with and carried for unidirectional sliging movement in said sleeve for movement between forward and rearward positions, and extending rearwardly from said sleeve in said latter position, c. a towing vehicle hitch element affixed to the rearwardly extended end portion of said hitch bar, d. a pin insertable transversely through said sleeve adjacent the open rearward end thereof, said pin being engageable selectively either in a closely fitting hole provided therefor in said hitch bar adjacent its rearward end, whereby to latch said hitch bar in its forward position, or in a longitudinally elongated slot formed therefor in said hitch bar forwardly of said hole, whereby to serve as a stop limiting rearward movement of said hitch bar, said hitch bar being laterally pivotable relative to said sleeve on said pin when said hitch bar is in its rearward position, e. resilient means carried by said sleeve and biasing said pin in a direction to project through said sleeve, and f. mannually operable means for retracting said pin from said sleeve against said biasing means, said hitch bar being formed to present a cam surface at the rearward end of the slot thereof, said cam surface being operable as said hitch bar approaches said forward position to deflect said pin outwardly from said sleeve against said biasing means.
Claim 2
Dependent Claim 255 words
A trailer hitch bar device comprising: a. a sleeve member adapted to be affixed to a towing vehicle to extend generally parallel to the direction of vehicle travel and opening rearwardly, b. a hitch bar normally coaxial with and carried for unidirectional sliging movement in said sleeve for movement between forward and rearward positions, and extending rearwardly from said sleeve in said latter position, c. a towing vehicle hitch element affixed to the rearwardly extended end portion of said hitch bar, d. a pin insertable transversely through said sleeve adjacent the open rearward end thereof, said pin being engageable selectively either in a closely fitting hole provided therefor in said hitch bar adjacent its rearward end, whereby to latch said hitch bar in its forward position, or in a longitudinally elongated slot formed therefor in said hitch bar forwardly of said hole, whereby to serve as a stop limiting rearward movement of said hitch bar, said hitch bar being laterally pivotable relative to said sleeve on said pin when said hitch bar is in its rearward position, e. resilient means carried by said sleeve and biasing said pin in a direction to project through said sleeve, and f. mannually operable means for retracting said pin from said sleeve against said biasing means, said hitch bar being formed to present a cam surface at the rearward end of the slot thereof, said cam surface being operable as said hitch bar approaches said forward position to deflect said pin outwardly from said sleeve against said biasing means.
Claim 3
Dependent Claim 183 words
The structure as recited in claim 1 wherein said sleeve is straight except that its rearward portion has rearwardly divergent side walls to form an angular throat, said pin extending vertically through the throat portion of said sleeve for slidable engagement in the slot of said hitch bar, said pin, throat and slot being so relatively disposed that when said hitch bar is moved rearwardly to the full extent permitted by engagement of said pin in the forward end of said slot, said hitch bar may be pivoted laterally on said pin to the extent permitted by the angular opening of said throat, the forward tip portion of said hitch bar projecting into the straight portion of said sleeve at all angular portions of said hitch bar when in said rearward position, the side edges of said hitch bar tip portion converging arcuately toward said tip, whereby said curved edge portions serve as cams against the straight portion of said sleeve tending to move said hitch bar into coaxial relation with said sleeve whenever a forward force is exerted on said hitch bar.
