A retail display sign of the swinging panel kind is provided in which the main frame structure is a gas-cored injection moulding e.g. in polypropylene. The gas core is a single cavity extending along the top rail (1A), the side posts (1B, 1C) and the outer portions of the lower rail (1D) of the frame. The hollow regions of the frame when viewed in transverse section are convex throughout their periphery in order to assist moulding and in particular in order to assist in centralising the gas core within the moulded structure. The frame structure may include depending connector formations for pairs of pivoted feet (5) which can be moved from positions at right angles to the frame to positions aligned with major planes of the frame. The use of a frame of generally oval cross section and a lower rail (1D) raised from contact with the ground provides a structure that is resistant to overturning in high winds. |
