ABSTRACT:
A dual magnification reversible spot mirror device includes two mirrors having different magnifications, e.g., 5X and10X, mounted back-to-back in a cylindrical frame ring which has an outer cylindrical wall surface from which protrudes a circumferential annular ring-shaped rib, and a mirror frame holder which has protruding forwardly from a base thereof a plurality of circumferentially spaced apart, longitudinally disposed flange walls which are elastically deformable in a radially outwardly direction from a longitudinal center line perpendicular to the base. Retainer lips protruding radially inwardly from inner longitudinal wall surfaces of the flange walls are forced radially outwardly in response to rearward forcible contact with the lips by the frame rib, whereupon the flange walls deflect elastically inwardly to an undeformed position in which the mirror frame ring with a reversible selected mirror facing outwards is captivated between a front wall surface of the base and rear surfaces of the flange wall lips. The base of the mirror frame holder is pivotably mounted to a mounting base which has suction cups protruding rearwardly therefrom for releasable attachment to a flat surface such as the vertical surface of a larger wall or cabinet mirror, or the horizontal surface of a table top or vanity.
