<p>A simple support frame to hold flexible presentation panels (3) has the panels looped over upper (9) and lower (5) bars with the lower bars set between two floor standing frames (4) and the upper bar supported by two support struts (8) between the floor frames and the upper bar. The support struts are located on springs in sockets in the ground frames. This enables the user to press down on the upper bar, compressing the spring and loosening the panels. In the released setting the springs stretch the panels.</p> |
