Abstract
Abstract A visual aid device for positioning of a towing vehicle for hitching to a trailer. A vehicle-attachable sighting rod assembly co-operates with a trailer sighting target assembly to guide the vehicle rearwardly into hitching position. Sighting and target rods are so placed as to come together when the vehicle reaches the hitching position. The sighting rod may be attached to be visible along the side of the vehicle, so that an unobstructed rear window is not needed. The target rod is then placed upon the ground to the side of the trailer coupling the same distance that the vehicle sighting rod is from the vehicle coupling. The target assembly may also have another sighting rod, which with the target rod is useful for vehicle direction control, if needed. The assemblies may also be used with the rear window, if it is not visually obstructed. In this case, the target assembly then being attached to the trailer tongue with the target rod rising vertically directly from the coupling to be seen through the window.

Claim 1
Independent Claim
111 words
A towing vehicle positioning aid for joining a hitch coupling of the vehicle to a mating hitch coupling of a trailer, the positioning aid comprising: a sighting assembly having an elongate sighting rod with one end suitable for a sighting reference, along with means for removable attachment of the assembly to the vehicle body in selective location so that the sighting end may be transversely aligned with the hitch coupling of the towing vehicle and visible by the operator along the side of the vehicle; and a trailer target assembly including a target rod and means for support of the target assembly upon the ground with the target rod vertically upstanding.
Claim 2
Dependent Claim
111 words
A towing vehicle positioning aid for joining a hitch coupling of the vehicle to a mating hitch coupling of a trailer, the positioning aid comprising: a sighting assembly having an elongate sighting rod with one end suitable for a sighting reference, along with means for removable attachment of the assembly to the vehicle body in selective location so that the sighting end may be transversely aligned with the hitch coupling of the towing vehicle and visible by the operator along the side of the vehicle; and a trailer target assembly including a target rod and means for support of the target assembly upon the ground with the target rod vertically upstanding.
Claim 3
Dependent Claim
105 words
The vehicle positioning aid of claim 1, wherein: the sighting assembly attachment means is adapted also for removable attachment of the assembly to the vehicle so that the sighting end of the sighting rod may be placed directly above the hitch coupling of the vehicle and at a height to be visible to the operator through the rear window of the vehicle; and the trailer target assembly support means is adapted also for removable attachment of the assembly to the hitch coupling of the trailer with the target rod vertically upstanding thereabove at least to the height of the sighting end of the sighting rod.
Claim 4
Dependent Claim
65 words
