Abstract
The invention relates to an oblong sign board casing comprising a reflector sheet provided with parallel embossings extending in planes substantially perpendicular to a longitudinal axis. The profiled reflector sheet is curved about 90.degree. round a longitudinal axis, whereby a self-supporting construction is obtained. This construction renders it possible to provide the front plate with a flange and a sharp edge at the bottom. The embossings cause an effective diffusion of the light, also towards the bottom face.
Claims2
A self supporting illuminated sign casing defined by a reflector of corrugated sheet, diffusing light means employing one or several light sources such as fluorescent tubes, said light sources being mounted on said reflector, and a front plate mounted at the edges of the reflector, the corrugations of said reflector sheet being substantially parallel embossings extending in planes substantially perpendicular to a longitudinal axis, said casing including:
- said corrugated reflector sheet comprising two substantially plane zones substantially perpendicular to each other and a curved intermediate zone having a radius of curvature of 3 to 20 cm, and by the front plate being secured to the two plane reflector zones perpendicular to each other, said front plate being further defined by a bottom portion with flange means and a sharp edge to enable placement of said sign board casing in adjoining relation to a proximate surface.
