Description

ELEMENT FOR LIGHT TABLET, LIGHT TABLET AND

LIGHT SHELF

Technical area

The present invention relates to a luminous tablet element, a luminous tablet comprising such an element and a luminous shelf comprising such a luminous tablet, intended to be used to form any type of storage rack and / or presentation of objects.

Prior art

Shelves are commonly used to form shelving. storage and / or presentation of objects. For this purpose, the shelves are arranged on a support or assembled to amounts to form shelves. The shelves thus formed can be freestanding or be attached to a wall, for example a wall. Such tablets can thus be used in industry, in shops or even in private homes. In order to indicate information on the objects carried by the tablets, for example products for sale, the tablets are often coupled to signaling elements, for example strips of label provided at the nose of the tablet. The labels may include any type of product information such as, for example, price, product references, brands, etc. Labels may also include any type of racking information, such as aisle, row, and so on. These indications thus make it easier to find the objects sought and / or to obtain information concerning the objects, in particular their price. These indications may be • coded, for example by means of a color code, a barcode or any other suitable code. The labels may be traditional labels for example printed on paper or any other equivalent medium. The labels can also be electronic labels, thin, provided with a display screen, for example liquid crystal. The content of the display of this screen can be controlled by a microprocessor, for example remotely controllable by means of the central computer of the store or the storage location.

The labels are often not very visible, not very readable and do not allow to highlight sufficiently the products they present. In order to overcome this problem, store and storage managers are increasingly planning illuminating systems, for example by means of light spots directed towards the labels to illuminate them. These illuminating systems are nevertheless impractical to install and expensive. In addition, the location of the spotlights must be uniquely adapted for each new rack configuration which makes their installation laborious. Finally, light spots can be easily damaged during traffic or by acts of negligence or even vandalism.

In addition, in order to better promote products and better differentiate sales areas, store managers are always looking for innovations in the presentation of products offered for sale.

The luminous tablet element thus makes it possible to effectively illuminate the signaling element in order to improve its visibility and readability. Moreover, the created visual effect is new and makes it possible to increase the differentiation and attractiveness of the products presented. The shutter mask allows in particular to focus the light on the signaling element. The element for luminous tablet according to the invention may be a tablet to which it is appropriate to add luminous means to transform it into a luminous tablet.

Said fastening means are preferably arranged to define a fastening plane substantially parallel to said bearing surface.

Advantageously, said fastening means have a shape selected from the group comprising at least one dovetail, a C-profile, an inverted V profile, an open inverted V profile.

Brief description of the drawings

The invention is described below, by way of non-limiting example, with reference to the accompanying drawings in which:

• Figures 1 to 7 are partial schematic sections of light shelf according to seven embodiments of the invention;

FIGS. 8A and 8C are partial schematic sections of shelf element illustrating three variant embodiments of the fixing means according to the invention, figures on which the label holder and the light means are not represented; FIGS. 9A to 9C are sections respectively, enlarged section in view and perspective of a light shelf according to the invention, figures on which the label holder is not shown.

Description of the embodiments

In general, with reference to FIGS. 1 to 7, the light shelf la-lk comprises a luminous tablet element formed of several parts joined to one another and provided with means for securing to a support (not shown) such as, for example, vertical uprights. The luminous tablet thus forms, with the uprights and other shelves luminous or not, a light shelf. The light shelf may also be carried by cleats fixed on a wall, for example a wall.

The element for a light shelf comprises in particular a plate defining a substantially planar upper bearing surface 2 and fastening means 5a-5k able to receive an interchangeable signaling element 3 such as, for example, a label holder receiving a label. The label may be a traditional paper, cardboard, plastic, or other type of label. The label may also be an electronic tag. The signaling element 3 may finally be any other suitable element. The fastening means are provided under the bearing surface. In the illustrated examples, the label is not shown.

The element for luminous tablet also comprises a shutter mask 4a-4k provided under the bearing surface 2 with which it defines a housing 5 provided with a front opening facing the front of the luminous tablet la-lk, this opening frontal being intended for at least partly blocked by the signaling element 3.

The light shelf la-lk comprises light means 6 (represented by a rectangle), arranged in the housing 5. These light means 6 are for example in the form of a light strip, for example a strip of LEDs, or a fluorescent tube, for example of the T5 type. The bearing surface 2 of the luminous tablet la-lk limits the upward diffusion of the light emitted by the luminous means 6. In addition, the shutter mask 4a-4k limits the dorsal diffusion (toward the back of the tablet luminous la-k) and downwards, light emitted by the light means 6.

The fastening means 5a-5k define a fastening plane substantially parallel to the bearing surface 2 so as not to limit the frontal diffusion of the light emitted by the light means 6. The front opening is thus maximum and allows frontal diffusion optimal light.

As detailed below, depending on the embodiment, the bearing surface 2 may comprise a plurality of first through holes 21 for example provided between the fixing means 5c-5f and 5k and the light means 6. These first through holes 21 allow the upward diffusion of the light emitted by the light means 6. Similarly, the shutter mask 4c-4g and 4k may comprise a plurality of second through holes 41 and / or third through holes 42. These second through holes 41 and / or third through holes 42 allow the diffusion downwards and / or backwards of the light emitted by the light means 6.

In these examples, the signaling element is a label holder 3 having a label (no represented). The label holder 3 is made of flexible and transparent plastic material. Each label holder 3 comprises an elongate blade 30 whose lower part is extended by a return 31 folded forward on the blade 30 in order to define, with the blade 30, a slot in which a traditional tag can be inserted. The upper part of the blade 30 is extended forwards and backwards by attachment lobes 32 of the label holder 3 intended to cooperate with the fixing means 5a-5k of the light shelf la-lk to ensure the fixing the label holder 3 on the luminous tablet la-lk. The label holder 3 can of course be of any other shape and made of any other material compatible with its use and the fixing means 5a-5k of the light tablet la-lk. Preferably, the label holder 3 and the label that it comprises, are translucent so that the light is perceptible through the label holder 3 and the label by an observer disposed in front of the luminous tablet la-lk.

Referring to Figure 1, the tray of the light shelf la comprises a tablet end end provided with a wide fold 20 defining the front edge of a light shelf la and a first groove. Furthermore, the plate has cutouts 22, aligned, substantially parallel to the front edge of the tablet, only one is shown. These cutouts 22 are deformed towards the underside of the light shelf in order to define second grooves. The first groove and the second grooves define a dovetail in which the attachment lobes 32 of the label holder 3 are housed to ensure the fixing of the label holder 3 on the luminous tablet 1a. In this first embodiment, the fixing means 5a are partly tangent to the front edge of the tablet.

In this first embodiment, the shutter mask 4a has a partial Z-shaped shape comprising a first wing 43 fixed under the bearing surface 2 of the light shelf 1a, a return 44 substantially perpendicular to the first wing 43 and extended by a second wing 45 substantially perpendicular to the return 44 and therefore substantially parallel to the bearing surface 2. The front end of the second wing 45 is provided with a tight fold 40 making the cutting edge of the shutter mask 4a inaccessible while preserving a maximum frontal opening. This tight fold 40 delimits a front edge of the shutter mask beyond the front edge of the tablet delimited by the wide fold 20. Thus, the tight fold 40 forms a support flange adapted to receive the support of the blade 30 of the label holder 3. The orientation of the label holder 3 is thus determined in advance in an optimized manner to ensure the readability of the information carried by the label.

The light means 6 are arranged in the upper rear corner of the housing 5 defined by the shutter mask 4a and the plate under the bearing surface 2. The shutter mask 4a has a plurality of second through-holes 41, aligned, substantially parallel to the front edge of a shutter mask and only one of which is shown. These second through orifices 41 allow the. downward diffusion of the light emitted by the light means 6 and symbolized by the arrow L2. The label holder 3 and the label also allow the frontal diffusion of the light emitted by the luminous means 6 and symbolized by the arrow L4 through the label holder 3. The luminous tablet 1a of this first embodiment thus allows the frontal diffusion L4 and downward L2 of the light emitted by the light means 6. The front diffusion L4 of light is produced by the front opening delimited by the front edges of the light. tray and. shutter mask through the label holder 3.

Referring to Figure 2, the tray of the light shelf lb has a front end of the tablet provided with a wide fold 20 defining the front edge of the light shelf lb and a first groove. The shutter mask 4b is substantially similar to the shutter mask 4a of the embodiment of the preceding embodiment and the fastening means 5b are partly tangent to the front edge of the tablet. The light shelf lb has an intermediate piece 7 in the form of a partial Z, the first flange 70 is disposed between the first flange 43 of the shutter mask 4b and the bearing surface 2. The return 70 and the second flange 72 of the workpiece intermediate 7 define a second groove forming, with the first groove, a dovetail. In this second embodiment, the fastening means 5b are tangent to the front edge of the tablet. The label holder 3 and the light means 6 are substantially similar to those of the previous embodiment. The luminous tablet 1b of this second embodiment thus allows the L4 and downward L2 frontal scattering of the light emitted by the light means 6. The front L4 light diffusion is achieved by the front opening delimited by the front edges of the light. tray and shutter mask.

With reference to FIG. 3, the plateau of the third embodiment is substantially similar to that of Figure 1. It differs in that it comprises a plurality of first through holes 21, aligned, provided between the fastening means 5c and the light means 6 and substantially parallel to the front edge of the tablet. These first through orifices 21 allow the diffusion, towards the top, of the light emitted by the luminous means 6 and symbolized by the arrow L1. The shutter mask 4c is substantially similar to those of FIGS. 1 and 2. It differs in that it comprises a plurality of third through-holes 42 provided through the return 44 and allowing the dorsal diffusion of the light emitted by the light means 6 and symbolized by the arrow L3. The label holder 3 and the light means 6 are substantially similar to those of the previous embodiment. Tablet Light of this third embodiment therefore allows the forward scatter L4 downward L2, L3 and dorsal to the above Ll of the light emitted ^'by the lighting means 6. In this third embodiment, the edge front of mask shutter 4c is not positioned beyond the front edge of the tablet and the label holder 3 has a height less than the distance between the plate of the second flange 45 of the shutter mask 4c. Thus, when the light means 6 are in operation, a luminous line is formed between the bottom of the label holder 3 and the shutter mask 4c. In addition, the luminous plate 1 ^' of this third embodiment also allows the front diffusion L4, downward L2, dorsal L3 and upward Ll of the light emitted by the light means 6. The intensity of the light ray is in particular superior to that of the light resulting from the frontal diffusion. This creates a new visual effect. The frontal diffusion L4 of light is thus realized by the front opening delimited by the frontal edges of plateau and mask shutter, a part being through the label holder 3, the other part being done by the light line. Referring to Figure 4, the tray of the light shelf 1d has a front end of a tablet provided with a tight fold 23 making the cutting edge of the light shelf 1d inaccessible. This tight fold 23 delimits the front edge of the tablet. The plate also has first through holes 21 allowing the diffusion of the light emitted by the luminous means 6 and symbolized by the arrow L1. The plate further comprises cutouts 24 aligned provided between the first through holes 21 and the tight fold 23. These cutouts 24 are deformed towards the underside of the light shelf 1d to define stops 25 able to receive the support of the holder. label 3.

The label holder 3 is substantially similar to the previous ones. As detailed below, the label holder 3 is nevertheless fixed to the shutter mask 4d and not to the plate. The shutter mask 4d has a partial Z shape including a first flange 43 fixed under the bearing surface 2 of the light shelf 1d, a return 44 substantially perpendicular to the first flange 43 and extended by a second flange 45 substantially perpendicular to the return 44 and therefore substantially parallel to the bearing surface 2. The front end of the second flange 45 is provided with a large ply 46 defining the front edge of the shutter mask and a first groove. The shutter mask 4d further comprises cutouts 47, aligned, substantially parallel to the front edge of the shutter mask and only one is shown. These cuts 47 are deformed towards the top of the shutter mask 4d in order to define second grooves. The first groove and the second grooves define a dovetail in which the attachment lobes 32 of the label holder 3 are housed to ensure the fixing of the label holder 3 on the shutter mask 4d. In this fourth embodiment, the fastening means 5d are partly tangent to the front edge of the shutter mask.

The light means 6 are substantially similar to the previous ones and the label holder 3 and the label allow the frontal diffusion of the light emitted by the luminous means 6 and symbolized by the arrow L4. The front diffusion L4 of light is produced by the front opening delimited by the front edges of the plate and the shutter mask through the label holder 3. The luminous plate 1d of this fourth embodiment thus allows the front diffusion L4, towards the low L2 and upward Ll of the light emitted by the light means 6.

According to another embodiment not shown, the plate does not comprise cutouts forming abutment, the label holder bearing directly on the front edge of the tablet.

Referring to Figure 5, the plate of the light shelf is provided at its front end with a complementary part 8 disposed under the bearing surface 2, prominently with respect to the plate. Thus the cutting edge of the tray is rendered harmless. This complementary piece 8 has a dovetail shape C with two grooves and is adapted to receive the lobes 32 of the label holder 3. The plate has first through holes 21 substantially similar to the previous ones and allowing the diffusion to the top of the light emitted by the light means 6 and symbolized by the arrow L1. The shutter mask 4e is substantially similar to that of Figures 1 and 2. It differs in that it comprises two sets of second through-holes 41, aligned, substantially parallel to the front edge of the shutter mask, the two sets of second through-holes 41 being substantially parallel to each other. The light means 6 are substantially similar to the previous ones. The luminous plate 1c of this fifth embodiment therefore allows the front diffusion L4, downwards L2 and towards the top L1 of the light emitted by the light means 6. The front diffusion L4 of light is produced by the delimited front opening by the end edges of shelf and shutter mask through the label holder 3. with reference to Figure 6, the set of ^"lf the light tablet is substantially similar to the above and includes first through holes 21. the shutter mask 4f has a recessed U-shape whose upper branch 47 is fixed under the bearing surface 2 of the luminous plate 1f and the lower branch 49 extends substantially parallel to the bearing surface 2. The shutter mask 4f is disposed under the bearing surface 2 in a prominent manner with respect to the plate, so that the cutting edge of the plate is rendered harmless The obturator mask 4f is provided with fourth holes sants 51 provided opposite the first through holes 21 so that the first and fourth orifices 21, 51 through allow the diffusion to the top of the light emitted by the light means 6 and symbolized by the arrow L1. The front end of the upper branch 47 of the shutter mask 4f is provided with a wide fold 52 defining the front edge of the light shelf 1f and a first groove. The front end of the lower branch 49 is provided with a fold tight 40 making the lower cutting edge of the shutter mask 4f inaccessible while maintaining a maximum frontal opening. This tight fold 40 is provided beyond the ample fold 52 so that the tight fold 40 forms a support flange adapted to receive the support of the blade 30 of the label holder 3. The light means 6 are substantially similar to the previous ones . Furthermore, the shutter mask 4f has cutouts 53 aligned, substantially parallel to the first groove, only one is shown. These cuts 53 are deformed towards the bottom of the shutter mask 4f in order to define second grooves. The first groove and the second grooves define a dovetail in which the lobes for fixing the label holder 3 are housed. In this sixth embodiment, the fixing means 5f are partly tangent to the front edge of the tablet. The light means 6 are substantially similar to the previous ones. The return 48 between the first and second branches 47, 49 of the shutter mask 4f comprises third orifices 42 substantially similar to those of FIG. 3 and allowing the dorsal diffusion of the light emitted by the light means 6 and symbolized by the arrow L3. The light shelf lf of this sixth embodiment thus allows the front diffusion L4, to the. low L2, dorsal L3 and upward Ll of the light emitted by the light means 6. The front L4 light diffusion is achieved by the front opening delimited by the front edges of the plate and shutter mask through the label holder 3 .

The various previous embodiments can of course be combined. Fixing between the parts constituting the luminous tablet la-f is by example provided by spot welding, gluing, riveting or any other suitable means.

With reference to FIGS. 8A-C, the luminous plate 1h may contain fixation means 5h-j, such as respectively a C-shaped profile 53 (FIG. 8A), an open inverted V profile 54 (FIG. 8B), a profile inverted V open 55 (Figure 8C). The shape of the signaling element 3, and in particular of its attachment zone, will of course be chosen to be compatible with these fixing means 5h-j. In these three embodiments the front edges of the plate and the shutter mask 4h-4j_ form a tight fold. Best way to realize the invention

With reference to FIGS. 9A-B, the plate of the luminous tablet 1k is substantially similar to that of FIG. 4. It differs in that it comprises first orifices 21 substantially similar to those of FIGS. to 6. The shutter mask 4k is substantially similar to that of Figures 1 and 2. It differs in that its first flange 43 ^' is extended at the rear by a flap 43' substantially perpendicular to the first flange 43 and to stiffen and consolidate the luminous tablet lk. The light shelf lk further comprises an intermediate piece 7 substantially similar to that of Figure 2. It differs in that its first flange 70 is extended at the rear by a complementary flap 70 'substantially perpendicular to the first wing 70 and to stiffen and consolidate the luminous tablet lk. The light means 6 and the label holder (not shown in this figure) are substantially similar to those described above. With reference to the FIG. 9B, the luminous plate lk of this preferred embodiment thus allows front L4 and downward diffusion L2 of the light emitted by the light means 6. The front diffusion L4 of light is produced by the front opening delimited by the front edges of plate and shutter mask through the label holder. The light shelf lk is also provided with longitudinal reinforcements 10 for stiffening the support surface 2 and means for securing the light shelf lk for example to vertical uprights (not shown) or any other suitable support. In this example, the securing means comprise lateral flaps 11 making it possible to stiffen the luminous plate 1k and to bear on abutments integral with vertical uprights, orifices 12 and a rear longitudinal flap 13.

Possibilities of industrial application

It is understood that the examples described are only particular illustrations and in no case limiting the fields of application of the invention. Those skilled in the art can make arrangements of size, shape and material to the particular embodiments of the elements for tablet, light shelf and light shelf, without departing from the scope of the present invention.

Thus, for example, the through holes may have any type of shape, circular, ovoid, square, rectangular or other and for example form characters or numbers. Similarly, the labels and / or label holder may be colored and / or include cutouts promoting the frontal diffusion of light. Also, the luminous means used can emit a light white or light of any ^other suitable color. Finally, the vertical and horizontal portions of the shutter mask can be inclined. Thus, the second wing of the shutter mask may be non-parallel to the bearing surface to allow a housing of dimensions greater than that of the front opening, or vice versa.
