发明名称 Front-loading poster frame device
摘要 A front-loading poster display device with a plurality of poster frame sections positioned around and connected to a backing member. Each of the frame sections have a base member affixed to the backing member and a spring-biased cover member rotatably attached to the base member. The ends of the frame sections are mitered at 45 DEG angles. The backing member is preferably connected to the base members of each of the frame sections by "Tog-L-Locs" or other sheet metal joining mechanisms. The ball-type pintle formations in each of the hinge mechanisms connecting the base and cover members together can have one or more elongated slots or recesses therein.
