Trailer tow mirror
A mirror assembly has a pair of telescoping tubular supports extending between a support base and a mirror head to provide adjustment of the mirror head toward and away from the support base. Friction shoes within the tubular supports releasably hold such supports against unintentional telescoping movement. Cooperating stops on the telescoping supports limit outward movement of the mirror head and prevent complete separation of the telescoping supports. The tubular supports are hingedly attached to the support base for rotation about a vertical axis, and cooperating detents and spring elements on the supports and support base releasably hold the supports against rotation.
1. A vehicle exterior rear view mirror assembly comprising:
a support base mountable externally on a vehicle;
a pair of vertically-spaced parallel hollow support tubes extending outwardly from said support base;
a mirror head having a mirror head housing;
a mirror mounted on said mirror head housing;
a pair of vertically-spaced tube receiving openings in said mirror head housing rearwardly of said mirror and facing toward said support base;
said support tubes being slidably received in said openings for providing movement of said mirror head toward and away from said support base;
said support tubes having open ends within said mirror head housing;
a pair of mounting arms on said mirror head;
said mounting arms extending into said support tubes through said open ends thereof;
said mounting arms and said support tubes being longitudinally movable relative to one another for providing movement of said mirror head toward and away from said support base; and
said base plate and said pair of mounting arms being molded in one-piece of plastic material.
