ABSTRACT:
This invention is a trailer hitch viewing device which attaches to the front of a trailer and assists the driver of the tow vehicle to connect a trailer to a tow vehicle. The device is designed so that, after initial installation and alignment of the mirror, the mirror can be easily detached by merely lifting it out of an anchor bracket. The mirror is designed to be removed after the trailer hook up has been successfully achieved and to be folded in the center to form its own protective storage and carrying case. After storage, the mirror can be replaced for subsequent use by merely lowering it into the anchor bracket. Because of the unique design of the anchor bracket, mirror and other mounting hardware, the mirror does not require realignment when replaced and the device is immediately ready for use as soon as the mirror is placed in the anchor bracket. This device is particularly applicable to horse and cattle trailers or other trailers which have a vertical bulkhead behind the trailer hitch receiver for attachment of the anchor bracket. Furthermore, the design of the mirror and mounting hardware is such that the mirror can also be used as a convenient auxiliary mirror in other locations when not in use for assisting the hook up of the trailer.
