Abstract: A mounting structure for a display panel (156) is disclosed. The mounting structure comprises upper and lower fixed extrusions (110), an upper panel mounting extrusion (152) to which the upper edge of the display panel (156) is secured and a lower mounting extrusion (122) to which the lower edge of the display panel (156) is secured. The upper mounting extrusion (152) includes a series of ribs (154.1, 154.2, 154.3) which engage with a recess (120) in the up per fixed extrusion (110). A locking extrusion (138) includes a pivot plate (150) which engages in the recess (120) of the lower fixed extrusion (110). It also has a formation (148) which engages in a socket (124) of the extrusion (122). The panel (156) is tensioned and secured by swinging the extrusion (138) downwardly about its line of contact with the lower extrusion (110). Unlocking is achieved by swinging the extrusion (138) in the opposite direction.

Abstract: A display panel (10) is mounted on an underlying surface (TSW) using three extrusions (20.1, 36.1, and 20.3). The extrusions (20.1, 36.1) are secured to the underlying surface in parallel but spaced positions. The panel (10) has stiffening elements (18) in pockets (16) along its edges. The elements and pockets are inserted into a recess (26) of the upper extrusion (20.1) and into a recess (26) of the lower extrusion (20.3). With the extrusion (20.3) lying along the line (L) its end (34) is inserted in the recess (44) of the extrusion (36.1). The extrusion (20.3) is then swung in an arc (arrow A) against the surface (TSW) to tension the panel (10). The extrusion (20.3) is then fixed to the surface (TSW).
