ABSTRACT:
A changeable display device comprising a support member created out of a plurality of parallel rails forming display channels and said rails being attached together by cross members. Oppositely colored rows of back plates are mounted to said rails. Display elements are rotatably mounted in an array in said display channels having opposite display sides. The display elements are rotated into either a first display orientation or second display orientation so that cooperating with said back plates a display may be formed. Each of the display elements has a camming member with a camming surface and elbow portions adjacent one of the rails and a C-shaped spring is disposed in a spring housing attached to the rails adjacent said camming member. The C-shaped spring is deformed by the action of the camming member and thus exerts a force against the camming member. This action of the camming member and the C-shaped spring results in a force which retains that display element in either of said first display orientation or said second display orientation and the spring also biases the display element into the first display orientation or the second display orientation.
