Abstract
A display device such as is used to display automobile service station price data in which a support surface (26) provides a display area (22,23,24,25) and an adjustable information strip (39) is slideable across the support face to present different information characters (40) in the display area and a reflective surface carried by the support face to reflect light through either translucent characters on opaque background areas of the strip or through translucent background areas of the strip having opaque characters.
Claims14
A display device comprising a series of at least two support surfaces, each support surface defining at least in part, a display area, and including an adjustable information bearing self-coiling tape having coiled portions at its opposite ends mounted for movement relative to said support surface, said strip having thereon a series of areas defined by characters and a series of areas adjacent the characters, wherein one of said series of areas is translucent, said strip being mounted for slideable movement relative to the support surface so that said characters can be sequentially presented in the display area, and a light reflective surface disposed behind the strip in the display area whereby light impinging on said reflective surface is transmitted through the translucent area of the strip present in the display area and wherein said support surfaces together with their respective information strips are arranged in side by side relationship, adjacent support surfaces being interconnected by a spacer means including a strip retaining flange, said flange being disposed in overlapping relationship with respect to adjacent strips at edge portions of their respective support faces, said spacer means including adjusting means for moving said retaining flange towards and away from the strip whereby the strip can be held locked against its associated reflective surface and released for sliding movement with respect to its associated reflective surface.
A display device comprising a series of support surfaces each defining at least in part a display area and being connected to an adjacent support surface by a spacer element, an adjustable information strip mounted for slideable movement relative to the support surface in each display area, each of said strips comprising a series of areas defined by characters and a series of areas adjacent the characters, wherein one of said series of areas is translucent, and each of said information strips having a coiled portion at its opposite ends and wherein a further series of support surfaces together with their respective information strips and interconnecting spacer elements is mounted substantially parallel to and spaced from the first mentioned series with the display areas of the respective series facing in opposite directions, the support surfaces of one series being out of register with the support surfaces of the other series whereby neighbouring coiled ends of adjacent strips in one series are located between the opposite coiled ends of a strip in the other series.
