DESCRIPTION:
BRIEF SUMMARY
This invention is related to a selective information display device used for advertising.
The changing needs of operators of display devices have made technique progress in this area, and today there are various processes allowing several pieces of information to be displayed successively.
The current advertising market, in particular where heavily publicized events are involved, does not find a suitable response to its needs in the use of such devices. Indeed, it has become indispensable to optimize the return of a poster campaign by having available means whose implementation is simple, rapid, and costs little, while offering a great amount of flexibility in the choice and modification of the order and duration of display.
The invention applies more specifically to display devices of the type of those which are composed of:
a magazine for storage of rolls containing informational posters on rolled up supple strips,
a display window allowing the display of information of a poster unrolled in front of it,
and an unwinder allowing selective unrolling of the posters out of their rolls and behind the display windows.
Each of the posters is equipped at one of its ends with an elastic return means (such as a spring) ensuring the rolling up of the poster inside its roll without any external action, and at the other end, with an external means for extracting against the opposing force of the return means and unrolling the said poster out of its roll.
The French patent No. 2 647246 proposes a solution to carry out such a display device. To that end, this device comprises:
a conveyor (magazine) in a closed-loop arrangement, driven by a motor and guided so as to pass in front of a display window,
a plurality of supports distributed along the conveyor and immovably attached thereto, each of these supports being intended to a receive a cartridge (roll) positioned at right angles to the travelling axis of the conveyor.
means ensuring a disconnectable fastening of the said cartridges on said supports,
retention means (unwinder) arranged permanently in a space situated in front of the path of the means for extracting the posters, when the cartridges are driven by the conveyor and in the vicinity of the display window.
means to control the motor and select posters that are capable of acting on the retention means, with a view to cause the unrolling of the poster in the area of display under the effect of the driving of the cartridge by the conveyor and to halt the conveyor when the poster is completely unrolled.
This device presents the drawback of not allowing direct access to a poster without having to make all of the posters which preceded it on the conveyor travel in one direction or the other, once the poster displayed behind the window has been disconnected from the retention means so that it can be put away in its cartridge.
The technical problem to be solved by the object of the present invention is thus to propose a display device that is easy to implement, costs little, allowing an easy definition and modification of the order and duration of the display of each poster and a maximal reduction in unproductive time between the operations of poster removal and display.
To respond to this problem, the fundamental concept of the invention consists in using a display device of the type summed up above and consisting of a self-supporting frame having two magazines for storing rolls arranged at its ends, behind the display window and on the level of the latter, in such a way that the aforesaid unwinder can ensure the unrolling of the poster or a magazine behind the window at the same time as the rolling up of the poster of the other magazine having just been presented and vice-versa.
Such a display device offers numerous advantages because it allows one to reduce to the minimum the unproductive time between the operations of poster removal and display since:
during the display time of one poster of one magazine behind the display window, another poster is selected in the other magazine,
the unrolling of a poster of a ma
