Assignee:

APCO Graphics, Inc. - Atlanta GA

International Classification:

G09F 702

US Classification:

40611, 40622, 24 673, 24822212

Abstract:

A directory sign assembled from individual modular sign plates, and an improved mounting clip for supporting the sign plates in assembly. The mounting clips have multiple sets of prongs spaced so that prongs of separate sets engage mounting flanges of one or more sign plates. The mounting flanges extend back from the front face of the sign plates to conceal the prongs and related attachment structure, and the end mounting clips have bases that conceal the ends of the sign plates.

Abstract:

A sign assembly having a frameless-appearing sign face may be removed from and replaced into the assembly. The sign assembly includes a sign face having an outer surface, an inner surface and a peripheral side. The assembly also includes a sign frame having a sign face channel that is adapted to receive a portion of the sign face adjacent to the peripheral side. The sign face channel is defined by an inner frame portion and an outer frame portion. The assembly also includes a mounting component having a face support that is attached to the inner surface of the sign face adjacent to the peripheral side of the sign face, an inner support that is adapted to bear against the inner frame portion of the sign frame, and an outer support that is adapted to bear against the outer frame portion of the sign frame. The invention also includes a method for mounting a sign face on a mounting component and a method for converting a framed assembly into a frameless-appearing assembly.

International Classification:

US Classification:

Abstract:

A suspended ceiling sign is provided for suspension within a vacant panel area, under a light fixture, in a suspended ceiling of a regular array of ceiling panels with each panel being peripherally supported within a suspended grid structure. The ceiling sign includes a hollow enclosure having an open top with a peripheral flange configured to engage the supporting grid structure around the vacant panel area. The enclosure has in one of its sidewalls a cutout portion with a translucent sign mounted therein. The bottom of the enclosure has a directed lighting aperture. Inside the enclosure, there is a truncated pyramidal baffle which is both light reflective and translucent. The pyramidal baffle is seated over the aperture in the enclosure bottom. The truncated top of the baffle may be either open or closed with a translucent material. Thus, light emanating from the lighting fixture above the suspended ceiling is partly reflected from the baffle face through the translucent sign, and partly diffused through the translucent baffle to light the aperture in the bottom of the enclosure.
