DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for fixing electronic modules or housings for displaying information such as prices or the like in retail shops or on any other site, e.g. storage areas or production factories.
The Applicant has recently proposed, in particular in French patent application FR-2 658 645, an installation including a plurality of display modules that constitute remotely-controlled electronic labels.
The installation serves to replace conventional card labels with display modules having liquid crystal screens and receiving display instructions from a control unit which centralizes all of the information relating to the various goods displayed in a single shop.
An important advantage of such an installation lies in making it possible to avoid the lengthy handling required for fully updating the prices of various articles on display in a shop, such as a supermarket.
The display modules are designed to be installed on the edges of the shelving on which the articles are placed. At present, the housings of the modules are fixed by means comprising rails running along the shelves and including slideways that engage in complementary grooves on said housings. The housings are shifted manually along the rails until they are in position relative to the articles with which they correspond.
Such fixing means are nevertheless not very satisfactory.
To install the housings, it is necessary for them to be entered one after anther in the exact order they are to appear along the shelving, starting from one end of the rail that carries them.
In addition, if one of the display modules needs to be changed, then all of the housings carried by the rail on one side or the other of the housing of the module that needs to be changed must themselves be disengaged from the rail.
A main aim of the invention is thus to propose a fixing device that enables this problem to be solved.
Document GB-2 249 854 already discloses a device for fixing at least one electronic module housing for displaying information relating to goods exposed in a shop, and in particular in a retail shop, the device comprising a rail designed to receive the housing and an intermediate part which carries at least one resilient locking member having at least one projection designed to co-operate with a groove presented by the rail for the purposing of holding said housing relative to said rail, the housing and said intermediate part presenting complementary means for fixing said housing on said intermediate part.
The different variants described in that document are not easy to handle. In particular, mounting the intermediate part on the rail requires the operator to perform relatively accurate movements at the rail, which is awkward.
Mounting operations also turn out to be lengthy.
Also, the housing is not held very securely.
An object of the invention is to mitigate these drawbacks.
According to the invention, the solution consists in particular in that the locking element has a catch designed to co-operate with a complementary projection on the intermediate part to hold said locking element in a retracted position against resilient urging thereof, the projection then being disengaged relative to the groove of the rail with which it co-operates, the intermediate part having a resilient branch which, while the housing and the intermediate part are being installed on the rail, is urged back by the web of said rail coming into contact with the catch, so as to disengage the catch from the complementary projection with which it co-operates, the locking element then resiliently urging the projection into the groove of the rail.
Thus, to fix the housing on the rail, the operator needs only to cock the locking element, and then exert a simple thrust force on the housing once it has been presented on the rail together with its intermediate part.
The fixing device proposed by the invention also has the advantage of being adaptable to shelving of different dimensions, and in particular shelves of different thicknesses.
