FR2791457A1 - Dynamic display system for advertising purposes has motor rotating array of lamellae on vertical axes to alternately hide and display contents of case with transparent front window - Google Patents

Abstract

The display consists of a case (10) with a flat floor supporting a variety of solid objects. There is a transparent glass or plastics window at the front and there is a row of vertical lamellae (12) in front of the solid objects and just behind the window. The edges of the lamellae may overlap. A motor (20) may turn a shaft (18) to rotate the vertical shafts (14) on which the lamellae are suspended. When the edges of the lamellae are together, the solid objects are hidden and a picture painted on the front of the lamellae is visible. Rotation of the lamellae through 90 degrees hides the picture and exposes the solid objects to view.

Description

The invention relates to display devices, in particular for public

  blicitaires. It applies in particular, but not limited to, the display of

  communication messages in shop windows.

  One of the disadvantages of large messages is that

  that, when placed in a display case, they obscure a par-

  important tie of light, and therefore tend to dim the interior

  of the room or clutter the exhibition space behind the window.

  In addition, their static presentation is not likely to attract the eye of the passerby, the shop window is often already crowded with a large number

of products and messages.

  To increase the attractiveness of the display panel, we know how to use

  variable flashing lighting systems, etc., allowing better sol-

  dismiss the attention of passersby. But these means do not provide any solution.

  tion to the difficulties mentioned above, namely the space taken up by the display panels, and the discomfort they cause inside the premises, both by the external light which they obscure and by the flashing or the variation in light, which can be unpleasant for people

  constantly evolving inside this room.

  The invention provides a device for overcoming all of these drawbacks, which provides a display that is both dynamic and large, with in addition an original design which is entirely likely to attract the watch out for passers-by outside the window.

  To this end, the invention proposes a device comprising a transparent blind.

  rent, movable between a retracted position and a deployed position, the blind having in this deployed position a continuous transparent surface interposed between an observer and a region located on the other side of the blind, in particular the interior volume of a room, and means

  to alternate the blind from the deployed position to the po-

  retracted position. The transparent surface of the blind is provided with a film

  bearing an impression on the surface facing the observer, in particular

  an advertising impression, visible in the deployed position of the blind by the observer, this film being able to conceal from the observer the region situated on the other side of the surface of the blind, while leaving essentially

  pass the light towards this last region.

  In a first preferred embodiment, the blind is a blind with parallel slats, and the means for alternately passing the blind from the deployed position to the retracted position are means capable of simultaneously rotating each of the slats around a axis

  longitudinal, from a position where they are joined and extend

  only in a common plane forming said surface of the blind, towards a

  position where these blades each extend in the direction of the observation

  tor, perpendicular to this common plane.

  In another embodiment, the blind is a roller blind, and

  the means for alternately passing the blind from the position

  bent to the stowed position are means for alternately

  unwinding and winding this blind on a drum rotates.

  We will now describe an example of implementation of the invention, in

reference to the accompanying drawings.

  Figure 1 is an elevational view of the device of the invention.

  Figure 2 is a plan view of the same device, installed in the

store window.

  0o Essentially, the device of the invention uses a blind 10 which is, in this preferred example, a blind with vertical slats 12, of the type known per se. These blades can be pivoted by a shaft 14 located at

  their ends, around a vertical central longitudinal axis 16. The pivo-

  The lamellae are simultaneously produced for example by means of a

  horizontal gear 18 with bevel gear driven by a rotary motor 20.

  In the deployed position (that is to say the position shown in FIG. 1 and in solid lines in FIG. 2), the blades 12 are substantially contiguous and

lie in a common plane.

  In the position after pivoting (retracted position, illustrated in dashed lines in FIG. 2), the blades 12 have rotated by about a quarter of a turn and

  all extend perpendicular to the common plane they occupy

pay in the deployed position.

  Characteristically of the invention, the slats 12 of the blind: 1) are made of a transparent material (plastic), and

  2) are coated with an advertising print 22 produced by applica-

  tion on each slide of a “One-Way Vision” type film, which is a film in itself known and marketed by various companies, in particular the 3M Company; such a film can receive an impression (by screen printing or by another technique) such that, seen by an observer on one side of the film, this impression seems to be formed on an opaque support whereas in fact it lets pass through a very large proportion (around 90%) of light

lighting up the film.

  This device can be arranged, as illustrated in FIG. 2, behind the showcase 24 of a store, being interposed between the surface of this showcase and a

  tray 26, inside the store, carrying various objects such as 28.

  The device 10 thus divides the space into two regions 30 and 32, the region mainly corresponding to the exterior of the display case and the store,

  that is to say where passers-by evolve, and region 32 inside the ma-

  gasin, with the exhibits 28 and the various people evolving in

  permanently inside the store.

  Thus, an observer located in front of the blind (outside the window) will see impression 22 and will not see what will be behind it, while, if he is behind the blind (in the store) , it will perceive it as if it were transparent, that is to say that the presence of the film will not hinder the passage of light rays through the blind (whose blades are transparent). The blind will switch alternately from the deployed position to the retracted position. In the deployed position (illustrated in solid lines), passers-by in region 30 will not see the products 28; they will only see messages from

  printing 22, which can for example be "hooks" advertising

  res. At the same time, the slats of the blind being transparent and the film practically forming no obstacle to the passage of the light rays

  coming from outside, people working in region 32 inside

  the store will not be hindered by the deployed blind.

  Sudden transition from this deployed position to the retracted position

  (illustrated in dashed lines) will suddenly reveal to passers-by the content of the

  trine, thus constituting a powerful means to attract their attention.

  At the same time, people inside the store perceive

  will barely see the change in light intensity resulting from the change

  position of the blind, the variation being of the order of 10% (in posi-

  When deployed, the film lets in about 90% of the light. in position

  retracted it lets almost 100% pass).

  Various implementation variants are of course possible.

  We can for example, instead of the blind with vertical slats, provide a blind

  reel, here consisting of a transparent sheet wound by a mo-

  tor on a drum driven in rotation. The passage from the position

  folded to the retracted position is with such a blind a little longer than with a blind with parallel slats, but on the other hand it is much easier to affix the film carrying the printed message to it, since this film will be applied from a single piece and will not have to be cut into strips

  and adjusted, as in the case of the blind with parallel slats.
