Description

The field of the invention is that of information display racks for communication or visual advertising at POS points of sale.
The displays of the invention are foldable columns on themselves and unfoldable with the advantage of being able to be transported and stored in excellent conditions, on the one hand, and to be installed very quickly on site, somewhere else.
More specifically, the invention relates to a two-sided display information display support respectively on two blank parts of substantially rigid and collapsible material, the blank portions being arranged for, in an unfolded state of the support, to be constrained in order to to constrain the presentation faces, a plurality of holding inserts, whose actions are exerted discretely distributed along said blank portions, being provided to maintain the presentation faces in their constrained state.
We already know, especially from the document FR 2,824,946 , such a display rack comprising, as means for constraining the blank portions, elastics and, as holding inserts, antagonist holding strips for the elastics and which, in the deployed position of the display stand, abut against abutment flaps flan portions and hinged flap flaps of the blank portions.
With such a display rack of the prior art, from a folded state, simply begin to unfold the support so that, under the action of the elastic strain, it unfolds completely automatically. Naturally, conversely, the folding of the support takes place against the action of the elastics of stress.
But such a medium has characteristics that may, under certain circumstances, not be appreciated by everyone.
It is actually a display that can be described as high-end. It is quite difficult to climb and, overall, its price is felt.
The applicant has therefore sought to develop a display stand of great simplicity, a price accessible to a greater number and a longer life and this is how he proposes his invention.

Incidentally, it is known in the prior art by the patent application US1987418A a display medium for a case and showcase which comprises two faces and a single insert of substantially rigid material comprising two secant fold lines so as to evolve in a folding state and a holding state. The invention relates to a display stand as defined in claim 1.
As claimed above, the display stand is very simple, both for use and for manufacture.
Advantageously, the lever portion of the wafer comprises automatic folding means around said one fold line in one direction or the other. Preferably, the nature of the material of the locking-unlocking plate is determined for a folding of the lever portion of the wafer under the action of its weight.

Thanks to this, simply unfold the display stand, to constrain its blank parts to constrain the presentation faces, which unfolds the holding plates and locking latch and makes them flat, the time to ensure the maintenance of the state forced faces, before, possibly with a slight shake, the lever portions of the pads do not switch to the locking position of the holding portions.

To close and fold the support, it is still enough to turn it to tilt in the other direction the lever portions of the pads until they resume their flat state, allowing their folding around their fold line contained in the plane of the edges of the blank parts and the folding of the two blank parts against each other, before the folding of the support.

It is in fact two methods of mounting and dismounting the support of the invention that the applicant also intends to claim.

The invention will be better understood with the aid of the following description of an embodiment of the display stand, its mounting and its dismounting, with reference to the appended drawings, in which - the figure 1 is a perspective view of a first embodiment of the display stand, in the expanded state; - the figure 2 is a perspective view of the top panels of the display stand of the figure 1 , being deployed; - the figure 3 is a perspective view of the panels of the figure 2 after deployment but before locking; the figure 4 is a perspective view of the panels of the figure 3 , after locking; - the figure 5 is a perspective view of a holding and locking insert, being deployed from the support of the figure 1 ; - the figure 6 is a view of the insert of the figure 5 in its plane state; - the figure 7 is a perspective view of the insert of the figure 6 in its locking position; - the figure 8 is a view, in its plane state, of an insert for holding and locking a display stand not belonging to the invention; - the figure 9 is a perspective view of the insert of the figure 8 in its locking position; - the figure 10 is a perspective view of the insert of the figure 8 , in the process of deploying the medium; - the figure 11 is a perspective view of the upper panels of an embodiment of the display stand not belonging to the invention, in the deployed state; - the figure 12 is a perspective view of the upper panels of the figure 11 after deployment but before locking; - the figure 13 is a perspective view of the upper panels of the figure 1I , being deployed; - the figure 14 is a perspective view of the upper display rack panels not belonging to the invention, after locking 5 and the figure 15 is a top view of an embodiment of the display stand not belonging to the invention, after deployment and locking.
The display stand of the figure 1 is in the form of a vertical column 1 deployed to two parts of blank 2, 3 formed in a single starting cardboard blank fairly light or cardboard, which is a rigid and foldable material. Each blank portion 2, 3 is divided into panels 4, 5, here three in number, adjacent to each other along thick fold lines 6, here two in number. All panels 4, 5 are identical to each other. It is the front faces of the panels 4, 5 which constitute the information presentation faces 1 I, 12 of the support column. The column of the figure 1 can be folded on itself by folding on each other panels 4, 5.
The starting blank, of rectangular shape, had two lateral free edges 13, 14 and two transverse edges 15, 16. From one of the lateral edges 13, was formed a lateral flap 17 beyond a line of folding which on the figure 1 is joined to the side edge 14. The flap 17 has been fixed, here by gluing, on the strip adjacent to the side edge 14 of the rear face 18 of the blank portion 3. The initial blank has been folded along a fold line 19 parallel to the side edges 13, 14 so that the two blank portions 2, 3 are identical and both extend between their side edges 19, 14 and 14, 19. The column 1 comprises, here one pair of panels 4, 5 of the same level of the two blank parts 2, 3, one holding and locking-unlocking insert 20 ( Figures 5 7 ). It is a wafer also issuing from a flat blank portion of rigid and foldable material of the same nature as the blank of the support column here having a complex shape. A first portion 21, rectangular, provides a holding function, a second portion 22, of substantially semicircular shape, provides a locking-unlocking function. The two parts are separated from each other by a first folding line 23. The plate can be also folded around a second fold line 24, intersecting the first, in this case at right angles, and extending parallel to the two effective side edges 25, 26 of the holding portion 21 substantially equidistant from the two. The fold line 23 corresponds substantially to a diameter of the semicircular portion 22, a diameter substantially equal to the length of the holding portion 21 between its edges 25, 26. Beyond the effective lateral edges 25, 26, the portion 21 is continued by two strips 27, 28 intended, after folding around the "edge" lines 25, 26, to be glued against the rear faces 18 of the blank portions 2, 3, for fastening the inserts.

The first portion 21, said maintenance of the wafer 20 may be described as holding insert 21, the other part, as will now be seen, lever 22 locking-unlocking the holding state of the insert 21.

From a flat state ( figure 6 ), the plate 20 can be folded in two i) around the first line 23 ( figure 7 ), with, on one side, the holding insert 21 and, on the other, the lever 22 or ii) around the line 24 ( figure 5 ), with, on one side, first insert and lever halves and, on the other side, second insert and lever halves. Because the two fold lines 23, 24 are intersecting, the wafer 20 can be folded only around one of the two fold lines, the wafer portions extending on either side of a folding line can only remain flat.

Thus, when the lever portion 22 is tilted around the fold line 23 ( figure 7 ), the holding portion 21 can not fold on itself around the line 24, the portion 21 is locked in the holding state, as will be seen better still further. Conversely, if the lever part 22 is turned back in the other direction around the line 23, until the plate 20 returns to its flat state, that is to say if the holding insert is unlocked. 21, we can then fold the plate 20 around the line 24 to allow the flattening and the folding of the column 1.

More precisely in this case, the quality and nature of the material of the wafer 20 allow a folding of the lever portion 22 around the first folding letter 23, in one direction or the other, which will be described as automatic, or possibly semi-automatic and this, thanks to the weight of this lever portion 22.

Thus, at each panel level of the column 1, there is fixed a holding insert 20, 21. Each insert is mounted between the two parts of the blank 2, 3, against their rear faces 18 to which are fixed, here by gluing, their two lateral strips 27, 28, the two effective side edges 25, 26 inserts extending here parallel to the side edges 14, 19 of the column 1.

In other words, the two blank portions 2, 3 are interconnected by a plurality of holding inserts 21, identical to each other, and whose actions are exerted in a discrete manner along the presentation faces 11 , 12.

Thus, for the assembly and disassembly of the column 1, the procedure is as follows.

Mounting

Column 1 being folded on itself, the two blank portions 2, 3, flat, their rear faces 18 against each other, the pairs of panels 4, 5 also folded against each other around the fold lines 6, the column 1 is unfolded, the blank portions 2, 3 are manually constrained by pressure on the lateral edges 14, 19, which brings them closer to one another and forces the blank portions 2, 3 and, with them, the presentation faces 11, 12. Concomitantly, the inserts 21 have also unfolded around their fold line 24 ( figure 2 ) until becoming plans ( figure 3 ). Then, and while maintaining the pressure on the lateral edges 14, 19 of the column, possibly by a slight shaking, the lever parts 22 of the inserts are automatically, or semi-automatically, tilted by their weight in their locking position. ( figure 4 ). The plane state of the holding inserts 21 is then locked by the levers 22, it is possible to release the pressure on the lateral edges 14, 19; the inserts 21 maintain the presentation faces 11, 12 in their constrained state, here curved.

dismantling

Column 1 is turned over so that the lever parts 22 can be tipped in the other direction under the action of their weight, until the plates 20 return to their plane state ( figure 3 ), allowing the inserts 21 to be folded around their folding line 24 parallel to the lateral edges 14, 19 of the column and contained in the plane of these edges, and thus the folding of the blank portions 2, 3 towards each other. the other, and folded flat against each other, before folding the pairs of panels 4, 5 over each other around the fold lines 6, alternately on one side and the other, accordion, and to maintain the assembly thus folded by any appropriate means, for example an elastic.
Retention inserts 21 are described associated with locking-unlocking levers 22 arranged to tilt under the action of their weight. One could also consider the locking lever unlocking lever under the action of an integrated flyweight. This solution, given the original objective, would naturally be much less interesting.

Embodiment 101 of the display stand of Figures 8-13 , not belonging to the invention, is distinguished from the first by its holding plates and locking-unlocking 120 shaped for the production of columns with more than two presentation faces. Also, the elements of the second embodiment homologous to those of the first will bear the same references as these, however preceded by the numbers 1 of the hundreds.
The plates 120 comprise a holding portion 121 but two locking-unlocking portions 122, 122 ', extending beyond the fold lines 123, 123' forming, in the expanded state of the column, the edges of the holding part 121.
The holding and locking-unlocking inserts 120 are manufactured as the inserts 20, however being differently shaped and fixed in the column.
Flat ( figure 8 ), the holding portion remains rectangular but the locking or unlocking parts or levers 122, 122 'have a trapezoidal shape, with a large base merged with the fold line 123 (123'). The wafer 120 may also be folded around a third fold line 124 intersecting, here too, the lines 123, 123 'at right angles. The holding portion 121, beyond its effective lateral edges 125, 126, perpendicular to its fold edges 123, 123 ', is extended by two strips 127, 128, intended, after folding around the edge lines 125, 126 , to be glued against the rear faces 118 of the blank portions 102, 103, for fixing the inserts.
From a flat state ( figure 8 ), the plate 120 can be folded in three i) around the two fold lines 123, 123 '( figure 9 ) with, in the center, the holding insert 121 and, on both sides, the levers 122, 122 'or ii) around the fold line 124 ( figure 10 ), with, on the one hand, first insert halves 121 and levers 122, 122 'and, on the other side, second insert and lever halves.

As for the plates 20, the plates 120 can only be folded around lines 123, 123 'or 124.

Thus, when the lever parts 122, 122 'are tilted around the fold lines 123, 123' ( figure 11 ), the holding portion 121 can not fold on itself around the line 124, the portion 121 is locked in the holding state, as will be seen even better still further. Conversely, if the lever parts 122, 122 'are rotated in the other direction around the lines 123, 123', until the plate 120 resumes its flat state, that is to say if it unlocks the holding insert 121, can then fold the plate 120 around the line 124 to allow the flattening and the folding of the column 101.

As for the plates 20, the folding of the lever portions 122, 122 'of the plates 120 is performed semi-automatically.

Thus, at each column level of the column 101, there is fixed a holding insert 120, 121. Each insert is mounted between the two parts of the blank 102, 103, against their rear faces 118 to which are fixed, here by gluing , their two lateral bands 127, 128, the two effective lateral edges 125, 126 of the inserts here extending orthogonally to the lateral edges 114, 119 of the column 101, that is to say here in a plane perpendicular to these edges .

In other words, the two blank portions 102, 103 are interconnected by a plurality of holding inserts 121, identical to each other, and whose actions are exerted in a discrete manner along the presentation faces. 111, 112.

It is interesting to note here that the fold line 124, allowing the folding of the column and its unfolding, extends in the plane of the two lateral edges 114, 119 of the column.

Thus, for the assembly and disassembly of the column 101, the procedure is as follows.

Mounting

With the column 101 folded on itself, the two blank portions 102, 103, flat, their rear faces 118 against each other, the pairs of panels 104, 105 also folded against each other around the fold lines 106, the column 101 is unfolded, the blank portions 102, 103 are manually constrained by pressing on the lateral edges 114, 119, which brings them closer together. one another and bomb the blank portions 102, 103 and, with them, the presentation faces 111, 112. Concomitantly, the inserts 121 have also unfolded around their fold line 124 ( figure 13 ) until becoming plans ( figure 12 ). Then, and while maintaining the pressure on the lateral edges 114, 119 of the column, possibly by a slight shaking, the lever parts 122, 122 'of the inserts are automatically, or semi-automatically, tilted by their weight. lock ( figure 11 ). The plane state of the holding inserts 121 then being locked by the levers 122, 122 'can relieve the pressure on the side edges 114, 119; the inserts 121 hold the presentation faces 111, 112 in their curved state.

dismantling

Column 101 is turned over so that the lever parts 122, 122 'can be tipped in the other direction under the action of their weight, until the plates 120 return to their flat state ( figure 12 ), allowing the inserts 121 to fold around their folding line 124 in the plane of the lateral edges 114, 119 of the column, and thus the folding of the blank portions 102, 103 towards each other and their delivery to flat, one against the other, before folding the pairs of panels 104, 105 on each other around the fold lines 106, alternately on one side and the other, accordion, and maintain the assembly and folded by any suitable means, for example an elastic. In the folded state, the fold line 124 is perpendicular to the edges 114, 119.

Embodiment 201 of the display stand of the figure 14 , not belonging to the invention, differs from the two preceding by its three presentation faces, 211, 212, 213 constituting the front faces of three plane portions 232, 233, 234, formed in two starting blanks 216, 217 in a material identical to that of columns 1 and 101.
Each starting blank, of rectangular shape, had two lateral free edges 235, 236 and 237, 238 and two transverse edges 239. From one of the lateral edges 236, 238 was formed, in each blank, a lateral flap 214 , 215, beyond a fold line which, on the figure 14 , merges with the side edge 235, 237. The flaps were also fixed by gluing, as on the columns 1 and 101.

The starting blanks 216, 217 have been folded respectively along two lines 218, 219 parallel to the free lateral edges 235-238 and delimiting the blank portion 234, thus in two portions. This third blank portion 234 is folded along the border line 235 for the folding of the column 201.

Thus, in the folded position of the column 201, but not completely folded, the two starting blanks 216, 217 are flat against each other, the blank portion 234 folded on itself around the fold line 235.

As in the two previous columns, the blank portions 232, 233, 234 of the column 201 are divided into identical panels 204, 205, 206. In the folded position, the column 201 is folded on itself by folding one on the other. other groups of a panel 204, a panel 205 and a half panel 206.

The column 201 comprises at each level of panels a holding and locking-unlocking insert 220 which is partially identical to the inserts 120 of the column 101, without the second lever portion 122 '. The elements of the inserts 220 homologous to those of the inserts 120 bear the same references as these, with, however, substitution of the number 1 by the number 2 of the hundreds.

The inserts 220 are mounted between the two blank portions 232, 233, near the side edges 218, 219 of the third blank portion 234.

The inserts 220 comprise a holding portion 221, a locking-unlocking lever 222, articulated to the holding portion 221 around the fold line 223, the two holding 221 and locking 222 parts, after being laid flat. , being foldable in two around the fold line 224 extend in the plane of the transverse edge 237 and the fold line 235 of the third blank portion 234

Thus, for the assembly and disassembly of the column 201, the procedure is as follows.

Mounting

The column 201 being folded on itself, the three blank portions 232, 233, 234 flat, the blank portion 234 itself folded in two, their rear faces 218 against each other, the groups panels 204, 205, 206 also folded against each other around the fold lines 206, the column 201 is unfolded, the blank portions are manually constrained by pressure on the side edges 235 and 237, which brings them closer to each other, bombs the blank portions 232, 233 and, with them, the presentation faces 211, 212 and substantially flatten the blank portion 234. Concomitantly, the inserts 221 have also unfolded around their folding line 224 until they become planes. Then, and while maintaining the pressure on the side edges 235, 237 of the column, possibly by a slight shake, the lever parts 222 of the inserts are automatically, or semi-automatically, tilted by their weight in their locking position. . The plane state of the holding inserts 221 is then locked by the levers 222, it is possible to release the pressure on the lateral edges; the inserts 221 keep the presentation faces 211, 212 in their curved state and the face 213 in a barely curved, almost plane state.

dismantling

The column 201 is turned over so that the lever parts 222 are pivoted in the other direction under the action of their weight, until the plates 220 return to their plane state, allowing the inserts 221 to be folded around their line of contact. folding 224 extending in the plane of the lateral edges 235, 237 of the column, and thus the folding of the blank portions 232, 233 toward one another and their resetting, one against the other, and folding the two halves of the blank portion 234 against each other, outside the blank portions 232, 233, before folding the panel groups one over the other around the fold lines 206, alternately on one side and the other, in accordion, and to maintain the assembly thus folded by any appropriate means, for example an elastic.

Embodiment 301 of the display stand of the figure 15 , not belonging to the invention, differs from that of the figure 14 by its fourth additional presentation side. The four faces 302, 303, 304, 305 are formed of the two starting blanks 306, 307, fixed to one another by still gluing a flap 308, 309 folded around a fold line forming a border 310, 311, of one of the starting blanks 306, 307 on an end lateral band adjacent to a lateral edge 312, 313 of the other of the starting blanks 307, 306. The starting blanks 306, 307 have folded in two along two fold lines forming side edges 314, 315 for the column, separating the faces 302, 303 and 304, 305.
In the example under consideration, the four presentation faces are of the same dimensions and such that, in the deployed state of the support column 301, they are nevertheless constrained and here only slightly curved and, in any case, prevented from 'be concavely distorted towards inside the column. This is the definition of the curved state that will be considered here.
Thus, the column 301, in the deployed state, has in cross section (horizontal) a square shape very slightly curvilinear.
Like the other columns, the column 301 is divided into a group of four panels of the same level, two adjacent groups being separated by four fold lines.
The holding and locking-unlocking inserts 320 of the column 301 always exert their respective actions discretely along the (height) of the column, are quite similar to those 120 of the column 101, with their bonding flaps, their holding portion 321 and their two locking-unlocking portions 322, 322 'hinged to the holding portion 321 around fold lines 323, 323', one of which 323 extends in the plane of the opposite fold-edging 314, 315, the other 323 'being parallel thereto and extending here in the dihedral of the blank portions 302, 305. The three holding and locking-unlocking portions 321, 322, 322' can be folded in half around a fold line 324 extending in the plane of the opposite side edges 310-313.
The locking-unlocking lever portions 322, 322 'are here, not trapezoidal, but triangular.
For the assembly and disassembly of the column 301, one proceeds in exactly the same way as for the other columns.
