ABSTRACT:
To prevent condensation on the mirror, it is heated with water from a supply tube connected from a showerhead pipe to a dispenser which disperses the heated water in either liquid or spray form, preferably from holes in a hose which is mounted in a rear temperature-control space and which surrounds the back of the mirror. The hose has an oval cross-section with holes on one of its flatter sides so that they will all face inward, toward the center of the mirror. Also the tube acts as a gasket to prevent the water from leaking through the mirror's front. The mirror is held by a flex-arm which includes breakaway flex-joints (hinge or ball), allowing rotational and translational movements. A supply tube is carried inside the flex-arm, has a friction fit in the ends of the arm, and is connected to the dispenser hose by a T-fitting. A relief slot in the mirror end of the flex-arm allows water which enters the space in the flex-arm around the supply tube to leave such space. The mirror is mounted in a frame with a back plate which is slightly larger than the frame so that the back plate spreads the back of the frame, causing its front part to be compressed, thereby to squeeze the mirror into a concave, magnifying shape.
