Abstract:

A mirror assembly is provided for use in “hitching” trailers to towing vehicles. The mirror assembly can be used for conventional ball and socket couplings, fifth wheel couplings and variations thereof. The mirror assembly is magnetically attached to the trailer tongue so it can be easily removed after coupling. The mirror assembly includes a telescoping stanchion mirror post and a swivel joint which can be vertically rotated. A ball joint connected to the back of the mirror allows the mirror to be turned in any of a variety of positions for precise alignment during the hitching process.

Abstract:

A wheel chock for tandem wheels including upper and lower spaced apart wedge members sized and configured for wedging engagement with facing surfaces of the tandem wheels. A threaded rod joins the upper and lower wedge members. The threaded rod is connected to each of the upper and lower wedge members such that rotation of the rod in a first prescribed direction causes translational movement of each of the upper and lower wedge members along the rod and toward one another, and such that rotation of the rod in a second prescribed direction causes translational movement of each of the upper and lower wedge members along the rod and away from one another. At least one of the upper and lower wedge members includes a longitudinal bore formed therein, a transverse bore formed therein and intersecting the longitudinal bore, and a pivot nut having a body and a threaded nut bore formed therethrough. The body is disposed within the transverse bore such that the threaded nut bore is positioned at an intersection of the longitudinal and transverse bores. A portion of the rod is disposed in the longitudinal bore and threadedly engages the pivot nut.
