Abstract: A sign assembly have a chassis assembly for supporting indicia plates and for providing proper horizontal alignment of the indicia plates. The chassis assembly includes two chassis members having a medial receptacle for receipt of a support panel and a receptacle for receipt of alignment members. The indicia plates include mating members on distal edges for cooperating with the chassis member alignment members. The mating members and alignment members have cooperating surface configurations to facilitate proper indicia plate horizontal alignment. A tamper resistant assembly prevents unintentional removal of the indicia plates from the chassis assembly.

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.

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 frame for directory or other applications, and having adjustable corners permitting the sign to assume orthogonal and nonorthogonal configurations. Each adjustable corner connector has first and second elements that respectively connect to contiguous ends of adjacent edge members making up the sign. The elements of the adjustable corner connector are pivotably interconnected at hubs that are spatially displaced from the edge members, so that the hubs fit within the outline of the assembled frame without interfering with the edge members making up that frame.

Abstract: Sign apparatus for directory or other applications and having removable sign inserts positionable at any location along a dimension of the sign. The sign inserts are held in place by a number of elongated rails located behind the inserts. Each rail contains an elongate track with a slotted opening facing the back side of the sign inserts. The tracks receive an end of an elastically-deformable fastener attached to the back of the sign insert. Each fastener expands within the track to prevent unimpeded removal of the insert, while permitting the insert to slide within the track for longitudinal positioning of the insert along the rails.
