DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

FIG. 1 illustrates a display device for merchandise items 1, in particular a gondola for example intended to be placed in a retail store, for example a supermarket.

This device 1 here comprises a base 2, two vertical uprights 3 extending from the base 2, a bottom panel 4 interposed between the two vertical uprights 3, and a plurality of shelves 5, or shelves, hung on the door. false on the uprights 3, on either side of the bottom panel 4, and which extend opposite the base 2.

The base 2 is here provided with four feet, whose height is for example adjustable, two side panels 7, a front panel 8 joining the two side panels 7, a rear panel (not shown) also joining the two side panels 7 opposite the front panel 8, and an upper panel 9 having a front edge 10 folded partially facing the front panel 8.

Each of the uprights 3 extends here vertically from the upper panel 9 of the base 2, substantially at half the depth of the upper panel 9, which depth is defined between the front panel 8 and the rear panel of the base 2, to a free end 11.

Each of these uprights 3 here has a rectangular section and has a front face 12 provided with a plurality of openings 13, a rear face 16 opposite to the end face 12 and also provided with a plurality of openings (not shown ), similar to the openings 13, an inner face 15 joining the front face 12 and the rear face 16 and provided with a plurality of notches (not shown) configured to allow the mounting of the bottom panel 4, with the aid of hooks (not shown) on each of these uprights 3, and an outer face 14 opposite the inner face 15 and joining also joining the front face 12 and the rear face 16.

Here, the outer face 14 is full in that it is devoid of notches but alternatively, the outer face of at least one amount could include notches similar to those of the inner face for mounting another bottom panel mounted on a base which would for example be provided with a vertical upright. It is in particular thanks to the arrangement described above of the gondola 1 that it is possible, on the gondola illustrated in FIG. 1, to have shelves 5 on either side of the bottom panel 4.

Alternatively, the uprights could extend from one end of the top panel of the base and shelves would be mounted only on the front face of these uprights and thus arranged only on one side of the bottom panel.

Each shelf 5 visible in FIG. 1 extends here in a longitudinal general direction, from one to the other of the uprights 3, and has a depth in the transverse direction of the shelf 5.

Each shelf 5 is here provided with an upper panel 20 forming a display surface for merchandise articles, hereinafter referred to as the outer surface 30, of a first side 24 extending transversely from the upper panel 20 and in the depth of the tablet 5, a second side opposite the first side 24 and also extending transversely from the upper panel 20 and in the depth of the shelf 5, substantially parallel to the first side 24, a front face 23 extending transversely from the upper panel 20 and in the length of the tablet 5, and a rear face 26, opposite to the front face 23, also extending transversely from the upper panel 20 and in the length of the tablet 5.

The tablet 5 is here mechanically secured to one of the uprights 3, at its first side 24, by a bracket 21 and, at the other of the uprights 3, at its two side 25, by a bracket 22.

Figures 2 to 5 show one of the tablets 5, taken separately, in different orientations and at different angles of view.

In Figures 2 and 4, the tablet 5 is disposed in a so-called use orientation, where its outer surface 30 is directed upwards; while in Figures 3 and 5, the tablet 5 is turned and its upper surface is directed downwards and not visible. On the contrary, in Figures 3 and 5, it is an inner surface 31 of the upper panel 20, opposite its outer surface 30, which is visible.

The tablet 5 here comprises several reinforcing pieces, hereinafter referred to as longerons 35 which are mechanically secured to the upper panel 20 by its inner surface 31, directly or indirectly, and which extend longitudinally substantially from the first side 24 to the second side 25 of the tablet 5.

The spars 35, here three in number, are distributed over the depth of the tablet 5 between the front face 23 and the rear face 26 of the latter and each have a substantially general shape called omega (see in more detail below). ).

Alternatively, the tablet may comprise only one or two longitudinal members or more than three longitudinal members 35.

The tablet 5 further comprises several holes 32, here circular, which are formed on each of the first and second sides 24 and 25.

Alternatively, the tablet 5 comprises more or less such holes 32 or lack thereof.

The tablet 5 further comprises locking members, hereinafter referred to here as two cleats 33, which are formed respectively on the first and second sides 24 and 25.

These tabs 33 are here arranged closer to the front face 23 of the rear face 26 and are configured to cooperate with the consoles 21 and 22 to lock the tablet in position 5 on the latter (see below in more detail).

Here, the front face 23 of the shelf 5 joins both the first side 24 and the second side 25 by two opposite ends of the front face 23 (see in more detail below); while the rear face 26 extends between two free ends which are in the immediate vicinity, but which do not join, the first side 24 and the second side 25, so as to form a space 36 allowing the passage of one of the respective consoles 21 and 22 configured to allow the mounting of the tablet 5 on the respective upright 3 (see in more detail below).

This arrangement here makes it possible to close so-called corners A and B of the tablet 5 and to leave at least partially open corners known as C and D of the tablet; noting that the closed corner A is located at the junction between the front face 23 and the first side 24, the closed corner B is located at the junction between the front face 23 and the second side 25, the open corner C is located at the of the rear face 26 and the first side 24, while the corner D is located at the rear face 26 and the second side 25.

The tablet 5 further comprises, at each of the junctions between the front face 23 and the first and second sides 24 and 25, a locking mechanism 34 configured to close the respective corners A and B.

It will be noted that the upper panel 20, the first and second sides 24 and 25, the front and rear faces 23 and 26, the catches 32 and the locking mechanisms 34 are formed in a single metal sheet having a thickness of, for example, between about 0.4 mm and about 1 mm. It will also be noted that the omega-shaped spars 35 are also formed in a single metal sheet having a thickness of, for example, between about 0.2 mm and about 1 mm.

Figures 6 to 8 show in more detail the front face 23, the rear face 26, one of the longitudinal members 35, the first side 24 and the second side, seen in section, but also one of the holes 32, the cleats 33, and the locking mechanisms 34.

In particular, as illustrated in FIG. 6, the front face 23 has an external front wall 40, which extends from the upper panel 20 and which is provided with a first vertical outer portion 41 extended by a second outer portion transverse 42, the latter extending inwardly of the tablet 5; and an inner front wall 43 provided with a first transverse inner portion 44 extending from the second transverse outer portion 42 and folded over the latter, the first transverse inner portion 44 being extended by a second vertical internal portion 45 in support against the first vertical outer portion 41, the second vertical inner portion 45 being extended by a third transverse portion 46 extending inwardly of the tablet 5 bearing against the inner surface 31 of its upper panel 20.

In other words, the inner front wall 43 is folded at least on the outer front wall 41 so that the front face 23 is formed by a front fold.

The rear face 26 has an outer rear wall 50, which extends from the upper panel 20 and is provided with a first vertical outer portion 51 extended by a second outer transverse portion 52, the latter extending inwardly tablet 5; and an inner rear wall 53 provided with a first transverse internal portion 54 extending from the second transverse outer portion 52 and folded over the latter, the first transverse inner portion 54 being extended by a second vertical internal portion 55 in support against the first vertical outer portion 51, the second vertical inner portion 55 being extended by a third transverse portion 56 extending inwardly of the tablet 5 bearing against the inner surface 31 of its upper panel 20.

In other words, the inner rear wall 53 is folded at least on the outer front wall 51 so that the rear face 26 is formed by a rear fold.

The spar 35 here generally comprises a bottom wall 47 extending transversely, in section, two legs 48 extending vertically and substantially parallel from opposite ends of the bottom wall 47, and two support lugs 49 '. also extending transversely, in section, respectively from the legs 48, opposite the bottom wall 47.

The two support lugs 49 are mechanically secured to the upper panel 20 by its inner surface 31, directly or indirectly. The mechanical fastening of the support lugs 49 of the spar 35 can be done by gluing, for example by interposing separation microbeads between the bearing lugs 49 and the inner surface 31, or by welding, in particular by laser welding. Such a laser welding can be implemented with a machine having for example a support support for docking the support lugs on the upper panel and a control and control unit configured to parameterize the machine with a predetermined power, preferably of a relatively low value, and with a predetermined focusing distance.

The spar may have a height between its support legs and its bottom wall, between about 10 mm and about 25 mm. Thus, the tablet may have a total height of between about 10.4 mm and about 26 mm while having a particularly effective weight-height ratio, as well as a predetermined mechanical inertia module according in particular to the French standard NF D 65-031, while having a particularly high resistance, for example of at least about 300kg / m2.

As also illustrated in FIG. 6, the hole 32 formed in the first side 24 is situated between the front face 23 and the spar 35 immediately after this front face 23, the catch 33 formed on this first side 24 is situated immediately after this same spar 35, and the locking mechanism 34 at the corner A is generally formed by a locking tab 57 from the first side 24 and folded over a first end portion 58 of the front face 23 which is folded and arranged against this first side 24.

As illustrated in FIG. 7, the second side 25 has a second outer side wall 60, which extends from the upper panel 20 and is provided with a first vertical outer portion 61, as well as a second wall internal side 62 provided with a first vertical internal portion 63 extending from the first vertical outer portion 61 and folded and thus resting on the latter, the first vertical inner portion 63 being extended by a second transverse internal portion 64 s'; extending inwardly of the tablet 5 bearing against the inner surface 31 of its upper panel 20.

In other words, the second inner side wall 62 is bent over at least on the second outer side wall 60 so that the second side 25 is formed by a second side fold.

As also illustrated in Figure 7, the locking mechanism 34 at the corner B is also generally formed by a locking tab 67 from the second side 25 and folded on a second end portion 68 of the front face 23 which is folded and arranged against this second side 25.

As illustrated in FIG. 8, the first side 24 has a first outer side wall 70, which extends from the top panel 20 and is provided with a first vertical outer portion 71, and a first wall internal side 72 provided with a first vertical inner portion 73 extending from the first vertical outer portion 71 and folded and thus resting on the latter, the first vertical inner portion 73 being extended by a second transverse internal portion 74 s'; extending inwardly of the tablet 5 bearing against the inner surface 31 of its upper panel 20.

In other words, the first inner side wall 72 is bent over at least on the first outer side wall 70 so that the first side 24 is formed by a first side fold.

FIG. 8 also shows an internal passage (not referenced between the first side 24 and a free end 37 of the beam 35 visible in this FIG. 8, which passage opens into the space 36 formed between this first side and the rear face 26. This passage is here configured to at least partially receive the console 21.

We will now describe in more detail, with reference to Figures 9 and 10, the beams 35 visible at least partially in Figures 2 to 8, which rails 35 are here identical.

The support lugs 49 of each spar 35 are located facing each other and present here a first bearing portion 75 and a second bearing portion 76 extending from the first portion of support 75 and folded and therefore supported on the latter.

Each support lug 49 is thus formed by a fold.

The second support portion 76 is here shorter than the first support portion 75 so that the latter has a free end 78 directed in the illustrated example to an inner space 77 of the spar 35.

The jambs 48 of each spar 35 are located facing one another and are here formed by a vertical straight portion 79 which extends from the second support portion 76, substantially on the side of or under the free end 78 of the first support portion 75.

The bottom wall 47 of each spar 35 here extends substantially opposite the free ends 78 of the bearing lugs 76 and at least partially encloses the internal space 77 of the spar 35.

This bottom wall 47 has a first bottom portion 80 extending transversely, in section, from the vertical straight portion 79 of one of the legs 48, a second bottom portion 81 extending from the first bottom portion 80 and folded and therefore supported on the latter. The first and second bottom portions 80 and 81 have substantially the same length so that the second bottom portion 81 extends here substantially to the vertical straight portion 79 of the leg 48 which extends the first bottom portion 80.

The bottom wall further has a third bottom portion 82 extending transversely from the second bottom portion 81 and folded and thus resting on the latter. The third bottom portion 82 is here more than twice as long as the first and second bottom portions 80 and 81 so that it extends substantially as far as the vertical straight portion 79 of the other of the legs 48.

The bottom wall further has a fourth bottom portion 83 extending from the third bottom portion 82 and folded and thus resting on the latter. The fourth bottom portion 83 here has a length substantially equal to that of the second bottom portion 81 and is directed towards the latter, without joining it.

The bottom wall further has a fifth bottom portion 84 extending from the fourth bottom portion 83 and folded and thus resting on the latter. The fifth bottom portion 84 here has a length substantially equal to that of the fourth bottom portion 83 and extends to join the vertical straight portion 79 of the other jambs 48.

In the example illustrated here, the bottom wall 47 is thus formed by the juxtaposition of three folds superimposed and separated from a central space 85. In addition, the arrangement is such that the first bottom portion 80, the second portion bottom 81 and part of the third bottom portion 82 are superimposed from the inner space 77 outwardly of the spar 35; and the fifth bottom portion 84, the fourth bottom portion 83 and another portion of the third bottom portion 82 are also superimposed from the inner space 77 outwardly of the spar 35.

FIG. 9 further shows that each support lug 47 is provided, in the vicinity of the free end 37 of the spar 35, with an extension 86 formed in the extension of its second support portion 76 and a recess 87 formed by the interruption of its first folded support portion 75. It will be noted that each spar 35 has, at its end opposite to the free end 37 (ends which will subsequently be undifferentiated and referenced only 37), the same extension 86 as well as the same recess 87.

Figures 11 to 13 show in particular the assembly of the spar 35 on the inner surface 31, at the corner C where is formed the space 36 between a free end of the first side 24 and a free end of the rear face 26.

The beam 35 is mechanically secured under the shelf 5, by the first support portions 75 of its support legs 49 which are positioned against the inner surface 31, and by the extension 86 formed in the extension of the second support portion 76 of its support tabs 49 which are positioned against the second transverse inner portion 74 of the first inner side wall 72 of the first side 24, which second transverse inner portion 74 is itself positioned against the inner surface 31.

Note that the front fold of the front face 23 and in particular the third transverse portion 46 of its inner front wall 43, the rear fold of the rear face 26 and in particular the third transverse portion 56 of its inner rear wall 53, the second side fold of the second side 25 and in particular the second transverse internal portion 64 of its second internal side wall 62, as well as the first side fold of the first side 24 and in particular the second transverse internal portion 74 of its first wall internal side 72, here each mechanically fastened to the inner surface 31 in a similar process to that used for the mechanical fastening of the longitudinal members 35, ie for example by gluing or laser welding.

The spar 35 illustrated in FIGS. 11 to 13 is the spar closest to the rear face 26. The spar 35 thus has a bearing lug 49 directed towards the third transverse portion 56 of the rear internal wall 53 of the rear face. 26, and the vertical straight portion 79 of a leg 48 partially facing the second vertical inner portion 55 of the inner rear wall 53.

As illustrated in FIGS. 11 to 13, the rear face 26 and the first side 24 are configured so that the respective back fold and the first side fold do not overlap. To do this, the third transverse portion 56 of the inner rear wall 53 of the rear face 26 and the second transverse inner portion 74 of the first inner side wall 72 of the first side 24 are interrupted before the respective ends of the rear face 26 and the first side 24 at the corner C. In other words, the third transverse portion 56 of the inner rear wall 53 of the rear face 26 and the first transverse inner portion 74 of the first inner side wall 72 of the first side 24 are respectively shorter than the overall length respectively of the rear face 26 and the first side 24.

Note that it is the same at the corner D, where the rear face 26 and the second side 25 do not overlap either. To do this, the third transverse portion 56 of the inner rear wall 53 of the rear face 26 and the second transverse inner portion 64 of the second inner side wall 62 of the second side 25 are interrupted before the respective ends of the rear face 26 and second side 25 at this corner D. In other words, the third transverse portion 56 of the inner rear wall 53 of the rear face 26 and the second transverse inner portion 64 of the second inner side wall 62 of the second side 25 are respectively shorter than the rest of the rear face 26 and the second side 25.

Figures 14 to 17 show in particular that the corner A is closed by the first folded end portion 58 of the front face 23.

This first folded end portion 58 is derived from an extension of the second vertical inner portion 45 of the inner front wall 43 of this front face 23.

This first folded end portion 58 is housed against the first vertical outer portion 71 of the first outer side wall 70 of the first side 24, at a first end 69 of the first side 24.

To do this, the first vertical inner portion 73 of the first inner side wall 72 of the first side 24 is interrupted at one end 88 and further has a notch 89 whose contour is L-shaped.

In particular here, the first vertical inner portion 73 of the first inner side wall 72 of the first side 24 is substantially the same length as the first transverse inner portion 74 of the first inner side wall 72 of the first side 24.
