ABSTRACT:
A frame device for holding and displaying sign panels. The panels are held in tension along the edges by spring-biased slide means. The slide means along each side are all moved to prespecified positions for changing the sign panels when the covers of the frame device sections are opened. Similarly, all of the slide means are placed in tension simultaneously along each side when the covers are closed. Large sign panels are held in place without adverse buckling and tearing and the mounting and removal of them is faster, more convenient and more practical.
