Definitions

  • the invention relates to a display case for receiving transparent advertising posters and the like, translucent, film-shaped information carriers, consisting of an in particular upright frame, with at least one, preferably on both broad sides of the showcase, transparent fillings, behind which the transparent information carriers or posters are arranged, where in the interior of the showcase spaced-apart illuminants, in particular tubular lamps, are installed and between the illuminants and the information carriers there is a lens that has zones of different light transmission, the areas of the diffuser that are orthogonal to the lamps have the lowest light transmission have and correspondingly with decreasing light intensity and increasing distance from the illuminant, the light transmission increases.
  • FR-A-2 322 414 describes two scattering letters, one of which is designed as a frosted glass pane and the other as a latticework.
  • the frosted glass pen represents a translucent spacer, which is arranged between the second scattering pen (the lattice work) and the information carrier to be arranged on this spacer.
  • Showcases of the type mentioned at the beginning are set up, for example, in public places or other suitable places which are open to the public. They are usually cuboid in shape and have transparent fillings and poster carriers on both broad sides, so that in the display case with a lighting device arranged inside, both surfaces serving as advertising surfaces are illuminated. It is also possible to choose a shape deviating from the cuboid shape, for example a triangular or circular shape, in which case illuminants are then arranged at a distance behind the transparent filling.
  • the invention has for its object to provide a showcase with an even better distribution of light, which also prevents warping caused by dampening the system areas caused by placing the poster or information carrier.
  • an air- and light-permeable spacer is inserted between the scattering letter and the information carrier.
  • the lens is made of transparent material, in particular plastic films.
  • zones of different light transmittance are formed by a color grid applied to the lens.
  • the color grid is formed from color dots which on the one hand reduce the light transmittance and on the other hand reflect the light. This effect also results in better light scattering.
  • the spacer is formed by a plastic fabric, scrim, knitted fabric or the like, which is arranged at a distance in front of the lens and against which the information carrier can be placed on the side facing away from the lens.
  • the spacer consists of a polyester fabric, which is formed from monofilament threads with a thread thickness of about 0.3 mm.
  • the formation of the spacer from a polyester fabric made of monofilament threads of the specified thread thickness means that only very few opaque areas are created, while the largest part of the surface of the spacer is light- and is permeable to air. Since the threads of the fabric also consist of translucent material, additional light scattering can also be achieved in that warp and weft threads are of different thicknesses or the type of fabric has twill weaves, for example.
  • a preferred embodiment is seen in the fact that in a showcase approximately 1.30 m wide, three vertically directed fluorescent tubes are arranged in a uniform distribution over the width.
  • the display case serves to hold transparent advertising posters 2 or similar translucent foils or poster-shaped information carriers. It consists of a preferably upright frame 3, which is only indicated schematically in the drawing.
  • a transparent filling 4 for example made of clear plastic film, is arranged on both broad sides of the display case 1, behind which the transparent information carriers or posters 2 are arranged.
  • the lens 6 has zones 7 of different light transmission.
  • the areas of the diffusing screen 6 that lie opposite the illuminants 5 orthogonally have the lowest light transmission. These zones are designated 8.
  • the light transmission increases correspondingly with decreasing light intensity and increasing distance from the illuminant 5.
  • the zones 7 of different light transmittance are formed by a color grid printed on the lens 6, for example from the finest white dots.
  • a translucent spacer 9 is inserted between the lens 6 and the information carrier 2.
  • the spacer 9 is formed by a plastic fabric or the like, which is arranged at a distance in front of the lens 6 and to which the information carrier 2 is placed on the side facing away from the lens 6.
  • the spacer 9 thus serves as a diffuser for the light rays and additionally as a support element for the information carrier 2.
  • A can be used as the starting material for producing the spacer 9
  • Polyester fabrics made of monofilament threads with a thread thickness of about 0.3 mm are used.
  • the mesh size of the fabric formed from it can be relatively large.
  • a showcase 1 approximately 1.30 m wide, three vertically directed fluorescent tubes 5 are arranged in a uniform distribution over the width, the edge distance of the outer fluorescent tubes being approximately 1/3 m.
  • This arrangement creates a power-saving lighting of the display case 1, which may even be suitable for the lighting to be supplied with solar cells.
  • the inventive design ensures uniform illumination of the information carrier 2 despite the small number of lamps 5 over the entire area.
