Abstract

A combination of earmuff and eyeglass assemblies (12, 14) are provided, that facilitate adjustment of the position of the eyeglass (40) on the wearer and the raising and lowering of the eyeglass, in a construction that avoids interference with movement of the earmuffs (20, 22) against each other. The eyeglass assembly includes a pair of temple bar devices (46, 48) that each comprises two pivotally connected bars (50, 52), with the first bar having a rear end (56) pivotally mounted on a top portion (134) of an earmuff shell (24), and with the second bar pivotally connected about horizontal and vertical axes (74, 81) to one side of the eyeglass. A ball-and-socket coupling (80) is mounted on the top portion of each earmuff shell, with each socket (102) having a vertical slot portion (110) that allows the temple bar devices to be pivoted up and down, and with each socket having a horizontal slot portion (112) that allows the earmuffs to move together. As the front end of the first bar starts to pivot down from a raised position, it lies in slight interference fit with a portion (104) of the socket, so the temple bar device tends to remain raised until firmly pushed down.
