A device for mounting of substantially plane plates is described. It comprises at least one first frame and one second frame, the frames preferably being rectangular, showing two adjacent side lists (1, 2), with a relatively small depth (3) between the forward and backward limiting planes. The frames are flexibly connected to each other, such that the frames may be swung in relationship to each other. The device is primarily characterized in that said frames are connected by at least one elastic means (14), which enables the frames to be swung around an axis (19) coinciding with the limiting lines in at least one of said limiting planes. |
