<p>An illuminated sign comprising a housing (12) which defines an opening and includes a light source (28) disposed therewith. Attached to the housing and covering the opening is a display assembly. The display assembly comprising a perforated outer plate (134) which defines front and back surfaces and includes a plurality of apertures (36) disposed therein. Secured to the back surface of the outer plate is a flexible, opaque diaphragm (138) including a plurality of slits (140) disposed therein which are aligned with respective ones of the apertures (136) of the outer plate (134). A second flexible opaque diaphragm (139) is also provided which includes slits (141) formed therein in off-set alignment with the slits (140) of the first diaphragm (134). The display assembly further includes a plurality of light-transmitting pegs (52), each of which are extensible through respective ones of the apertures and slits which are aligned with each other. The slits are sized and configured to frictionally retain the pegs within the display assembly when the pegs are extended therethrough, and to block the passage of light from the light source through the aperture of the outer plate when the pegs are removed or not extended therethrough.</p> |
