ABSTRACT:
A display board comprises a frame, two longitudinally displaceable legs extending in the plane of the board, a support articulated to the top of the display board and arranged to be swung at an angle to the plane of the board and a pair of struts between the board and the support to secure the latter in a swung-out position. Each of the struts is articulated to a respective leg of the board and to a component which is axially displaceable to a limited extent on the support. When the support is swung-in to a position in which it extends substantially parallel to the plane of the frame, the articulation points of the struts on the respective legs are located above the said axially displaceable component and therefore above the articulation points of the struts on the support. An extension member is telescopically arranged in the support and can be secured in position by a clamping member mounted on the support. The clamping member also serves to limit axial movement of the axially displaceable component.
