Display panel, has tensioning device blocking lateral slides in intermediate position between two positions, where parallel lateral slides are extended longitudinally along direction, and mounted movably on fixed frame

摘要

The panel (1) has parallel lateral slides (11) extended longitudinally along a direction, and mounted movably on a fixed frame (2) for being displaced between two positions. A display (4) is tensioned in one of the positions, and the display is released in other position. A tensioning device (18) e.g. screw system, blocks the lateral slides in the former position. The tensioning device blocks the lateral slides in an intermediate position between the two positions. The device (18) has a screw (19) mounted on the frame.
