<p>The picture frame enables the picture to be changed, without dismantling the frame, by means of opening the central part of the back of the frame to remove or insert the picture. The back is in two parts, one of which opens. The fixed part of the periphery of the back can be made of one single cut-out piece or several pieces joined to one another. The peripheral frame parts have cut-out pieces which fit together. The peripheral frame part acts as a support for hanging lugs for the picture. The suspension piece consists of two opposite facing bends, in the opposite direction, like the letter S, or in the same direction like a C. One of the bends fits onto the back, and the other holds the hanging cord.</p> |
