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: A display frame for a poster having a top edge and at least two side edges includes a resilient first edge support for the top edge of said poster, a pair of resilient second edge supports for at least the side edges of said poster, and a plurality of resilient fastening elements associated with said edge supports for fastening said edge supports together in a frame-like manner. A pair of generally L-shaped internal angle fittings are employed for securing the pair of second edge supports to opposite ends of the first edge support. The rear of the first edge support is positioned offset and forwardly of the rear of the second edge supports so as to define therebetween a display slot whereby a poster may be removably slid into said display frame from above, rearwardly of the first edge support with the lateral edges of said poster being slidably received in a slotted channel defined by the second edge supports.

Abstract: A picture frame device which allows the framing straight members to be removed from the front of the frame device by pivotally rotating the corner joints and has a space formed in a container installed behind the exhibit or the exhibit held between holding sheets, for containing many other exhibitable sheets than the exhibit such as pictures and testimonials.
