TITLE: Information display and method for the manufacture of such a display.

The invention relates to an information display comprising a folded flat state and an unfolded state of use in volume. The invention also relates to a method for the manufacture of such a display.

In the field of point-of-sale (POS) advertising, advertising media in the form of cardboard columns are known.

Very often, these advertising media devices, nicknamed "TOTEM", are delivered flat and put in volume on site. Many devices exist on the market and require, however, complex and expensive mechanisms for their volume.

Document FR-2.824.946 or document FR-2.795.217 discloses advertising media devices comprising elastic members designed to cause an automatic deployment of the structure. With such media, just start to unfold the support so that the full volume of the media is automatic.

Such advertising media, however, have the disadvantage of the establishment of elastic members under tension, which makes the complex manufacturing and increases the cost of the device.

Another disadvantage of such devices comes from the difficulty of folding the support against the action of the elastic members.

The purpose of the present invention is to overcome the aforementioned drawbacks by providing a simple and inexpensive manufacturing display.

More particularly, an object of the invention is thus to provide a display including automatic deployment, the manufacture of which does not require the installation of elastic members under tension.

Another object of the invention is to provide a display whose volume is automatic, the device remains easy to fold in its flat state. Another object of the invention is to provide a method for the manufacture of such a device.

Other goals and advantages will become apparent from the description which follows, which is given for information only and which is not intended to limit it.

The invention firstly relates to an information display having a flat folded state and an unfolded state of use in volume, constituted by a sheath of semi-rigid material comprising at least two longitudinal fold lines for the folding of said sheath, said longitudinal fold lines defining at least two presentation faces, said display further comprising means for holding said presentation faces in unfolded state of use.

According to the invention, the means for holding said presentation faces in the state of use comprise, on the one hand, at least one elastic link, internal to said sleeve and joining two said lines of longitudinal folds between them, and of on the other hand, at least one spacer, internal to said sheath and associated with said elastic link, and wherein said spacer has, on the one hand, two end ends with stop function and, on the other hand, hooking means of said link associated elastic, able to allow, on the one hand, the setting of said elastic link by interlacing said spacer, thus tending to open the sleeve by the creation of biasing force binding said two lines of longitudinal folds approximation l towards each other and, on the other hand, the internal retention of the spacer in the sheath, said terminal ends of said spacer being able to abut respectively at the level of the two said longitudinal fold lines, against said restoring forces.

The invention also relates to a method of manufacturing a display as mentioned above, from a sheet of semi-rigid material flat, previously grooved and / or folded for producing said at least two longitudinal fold lines, comprising the following steps:

a sleeve is formed by folding the sheet of material semi-rigid and by gluing or stapling two of its edges,

one or more elastic links are secured to the sheath, in particular without tension, the or each of the elastic links joining two said longitudinal fold lines; the elastic or each elastic tie is stretched with the aid of an associated spacer, by embracing said elastic link on said spacer, said spacer cooperating in abutment with said two longitudinal fold lines, in the unfolded state of use in volume.

The invention relates to an information display 1, having a flat folded state and an unfolded state of use in volume. This display consists substantially of a sheath 2 of semi-rigid material, such as in particular cardboard or plastic.

This sleeve comprises at least two lines 3 of longitudinal folds for its folding, especially in the folded flat state of the display unit 1, as shown in FIG. 1. Optionally, the sleeve 2 also has at least one fold line 4. crosswise to fold it flat in the direction of the height. In the case of a sheath of low height, this line 4 is however not necessary (not shown).

The display unit 1 further comprises means for holding said presentation faces in the unfolded state of use, as illustrated in FIG. 2.

According to the invention, the means for holding said presentation faces 5, 6; 51, 52, 61, 62 in the state of use comprise, on the one hand, an elastic link 7, internal to said sheath 2, and joining two said lines 3 of longitudinal folds with each other, and on the other hand, less a spacer 8, internal to said sheath, and associated with said elastic link 7. Said spacer 8 has, on the one hand, two terminal ends 9 with stop function and, on the other hand, attachment means 10 of said associated elastic link.

According to the invention, the attachment means 10 of the spacer enable the said elastic link 7 to be tensioned by the interlacing of the said spacer, thus tending to the opening of the said sleeve by the creation of biasing force Fi binding the said two lines 3 of longitudinal folds towards the one towards the other.

On the other hand, the end ends 9 and the hooking means 10 of the spacer allow the spacer 8 to be held internally in the sleeve 2. The end ends 9 of the said spacer are able to come into abutment respectively said two lines 3 of longitudinal folds, against said elastic return forces.

Thus, as illustrated in FIG. 7, in the state of use, the spacer exerts forces F ₂ on the sheath that oppose the elastic return forces Fi.

The display unit according to the invention makes it possible, unlike the device of the state of the art, not to require any installation of elastics under tension during manufacture. The final tension of the elastic, particularly necessary for the complete volume of the display, is obtained, especially after deployment of the sheath, after the manual placement of the or spacers 8, and their interlacement by the elastic ties 7. The spacer therefore has the function of stretching the elastic link, stretching it.

According to one embodiment, the or each of the elastic links 7 can exert a particularly weak adapted tension on the sheath 2 to allow its easy folding, especially accordion, in said folded flat state of the display and, secondly, allows, however, automatic volume setting, at least partial, under the action of one or more elastic links during the deployment of said sheath. As already mentioned, the final tensioning of the elastic link 7 is obtained, especially in the state of use, only after implementation. place of the spacer 8 associated, especially once the sleeve unfolded.

More particularly, the full volume is possible in a second time by the tensioning of the elastics, which are manually entwined around the spacers, spacers also serving as a stop limiting the action of the elastic until obtaining the desired volume.

According to another embodiment, the tension of the elastic link or links is not sufficient to allow the automatic volume of the sleeve. This automatic scaling is however possible in the case where the spacers are previously placed in the sheath and entwined by their associated elastic.

As illustrated in the figures, said spacer 8 may consist of a sheet of material, in particular of cardboard, flat, rigid or semi-rigid, whose length is equal to the predetermined distance between said two lines 3 of longitudinal folds in said unfolded state of use. The spacer 8 must be of sufficient rigidity not to bend under the action of the restoring forces of the elastics 7. It may be cardboard sheets of compact or corrugated cardboard, of sufficient rigidity and adapted to oppose said elastic return forces (Fi). The attachment means 10 of the spacer 8 allow the spacer to be interlaced by said elastic link 7 in order to put it in tension. As illustrated in the figures, according to the examples, the attachment means 10 may consist in particular of two pairs of notches 11 made respectively on two lateral edges, in particular longitudinal edges, opposite the sheet of material, of the spacer 8 According to these examples, the lateral edges, in particular the longitudinal edges, between the notches of the same pair may have a convex profile 14. The end ends 9 may be widened.

According to the example of Figure 7, in the unfolded position of use, the elastic link 7 embraces the spacer 8 through consecutive notches 11. The elastic is supported on both sides of the sheet of material of the spacer 8, on the one hand transversely to the spacer 8 between the opposite notches of the two lateral edges, and secondly, longitudinally to the spacer, on the other side of the sheet of material, at the level of the convex profile 14 and the terminal ends 9 widened, moreover.

In this example, the spacer 8 makes it possible to stretch the associated elastic link by a length corresponding to twice the width of the spacer 8 defined between two opposite notches 11.

The elastic link 7 can pass through the sleeve 2 at openings made on the two lines 3 of longitudinal folds, stops 12, in particular metal, being provided at the ends of said link 7, able to engage outside said sleeve 2.

The sheath 2 may have at least two lines 4 of transverse folds to fold the sheath accordion such as shown in particular in Figure 1. Advantageously, these transverse fold lines can be obtained by creasing. In order to fold the sheath accordion, the direction of the creases is alternated on the height of the sheath.

As illustrated in FIG. 10 according to one embodiment, the sheath 2 can be obtained from a sheet of folded material, in particular previously grooved or folded, the edges of said sheet being secured to each other by stapling or gluing to using a flap 15, including internal.

Alternatively, the sheath 2 can be obtained from several sheets of material secured to each other to form said sheath by any suitable means (gluing, stapling or other). According to the examples of the figures, in the state of use, the section of the sheath may be elliptical, cylindrical, polygonal, in particular diamond.

The example of FIGS. 1 to 7 illustrates, in particular, a sheath of elliptical section, comprising in particular two presentation faces 5, 6. The example of FIGS. 3 to 10 is of polygonal, diamond-shaped section, comprising four presentation faces 51, 52 , 61, 62.

The invention will also relate to a manufacturing method a display according to the invention from a sheet of semi-rigid material flat, previously grooved and / or folded in particular for the production of said at least two lines 3 of longitudinal folds, and possibly of said at least one line 4 of transverse fold. The process according to the invention has the following steps:

a sleeve 2 is formed by folding the sheet of semi-rigid material and by gluing or stapling two of its edges,

one or more elastic links 7 are secured to the sheath 2, in particular without tension, the or each of the elastic links joining two said lines 3 of longitudinal folds, in particular in a folded flat state of the sheath,

the elastic or each elastic link 7 is stretched by means of an associated spacer 8 by embracing said elastic link 7 on said spacer 8, said spacer 8 cooperating in abutment with said two lines 3 of longitudinal folds, during the state unfolded volume usage.

The step of placing the elastic links 7 is illustrated in particular in FIGS. 11 and 11a. During this step, the sheath may in particular be slightly volume manually, to allow the establishment of elastic links, without any tension.

The different steps of setting up the spacer, in particular a cardboard plate, are illustrated according to FIGS. 12, 12a, 13 and 14. During these steps, the spacer is inserted in such a way as to position and interleave. the link through the notches 11 of said spacer on the same side edge.

As illustrated in Figures 13 and 14, the elastic link 7 is then manually tensioned until the link 7 embraces the spacer cooperating with the other two notches 11, on the other side edge of the 8. The tensioning of the elastic causes the approximation of the longitudinal fold lines 3 until they abut against the end ends of the spacer 8. It should be noted that when the spacers 8 are arranged in the sheath 2 and the elastic links 7 under tension, the display 1 can be folded flat, as shown in Figures 15 and 16, thanks to the longitudinal fold lines and the transverse fold lines 4, the two faces 5, 6 of the sleeve then being in contact with each other. When the user begins to unfold it, as shown in FIG. 17, the elastic links 7 cause the device to be automatically and completely volume-adjusted, as shown in FIG. 18, in particular until the spacers 8 cooperate in abutment with the sheath 2. It is particularly in this form, fully assembled and folded flat that the display is preferably delivered thus constituting an automatic display display. The display can be maintained in the folded state, packaged with streamers, bagged, or kept in cardboard packaging. The spacers 8 can be obtained by a stamping step.

We then develop the displays of Figures 19 to 24, which can be used alone, independently, in "columns" for the presentation of information, or can be assembled into a construction, including an arch as illustrated in Figure 29.

The sleeve of Figure 19 is in a semi-rigid material such as cardboard, obtained such as for example, from a sheet of folded material whose two edges of the sheet are secured together by gluing or stapling. The sheath 2 has four lines 3 of longitudinal folds, to fold the sleeve flat. The sleeve 2 has, in addition, a single line 4 of transverse fold, at half its height, in order to fold flat the sleeve in two, in the direction of the height. The sheath 19 is equipped with two elastic links 7 joining two said lines 3 of longitudinal folds, vis-à-vis. These elastics are located on either side of the line 4 of transverse fold. As illustrated in FIG. 20, each elastic link 7 may be associated with a spacer 8 inserted into the sleeve, allowing the elastic linkage to be stretched during the engagement of said spacer, as illustrated in the detailed views of the Figures 20a, 20b and 20c. Said spacer has already been developed previously and is not redeveloped. It is of the type comprising two pairs of notches on each of its lateral edges, having enlarged end ends, and a convex profile between the two notches of the same pair. The sheath of this display will allow, in the unfolded state of use to stand on one of the bases of the sheath, polygonal section, including square. In addition, the base can be completed by a stabilizing foot 70 consisting of a sheet of semi-rigid material, such as in particular a cardboard, particularly corrugated, assembled through notches 71 made at a said end of said scabbard. The notches 71 are two in number, on two opposite faces of presentation and are opening below the end of the sheath.

As illustrated in FIG. 21, the display unit consisting of the sheath 2, the elastic links 7, the struts 8, and the stabilizing foot 70 can be folded flat thanks to the transverse fold lines 3 during a first step. In a second step, this display can be folded in the direction of the height through the line 4 of transverse fold for a small footprint, flat.

The sleeve developed in Figures 22 to 24 is relatively similar to that of Figures 19 to 20. It differs in particular in that it has no stabilizing foot, and in that the four lines of longitudinal folds are such that the section of the sheath of the display in the unfolded state of use is rectangular, not square.

As illustrated two display units according to FIG. 21 and a display rack according to FIG. 24 can be folded back into their folded flat state in order to be packaged in a cardboard box, especially for the preparation of a construction of a arch 80 as shown in Figure 29.

This arch 80 consists of three displays, one of which constitutes a cross 81 of said arch 80, and the other two respectively constitute two columns 82 for the support of said cross 81.

More particularly, according to the example illustrated in the figures, two display units according to FIG. 21 are deployed in an automatic manner as illustrated in FIGS. 26a and 26b in order to constitute the columns 82 of said arch 80. A display unit according to FIG. deployed automatically, as shown in Figures 27a and 27b.

Advantageously, the sheath of the display units constituting a column 82 of the arch 80 has a nesting opening 83, fitted to the section of the sheath 2 of the crosspiece 81.

Advantageously, this opening 83 is constituted by a cut, preferably without removal of material, to define two guide flaps 84, which will be turned towards the inside of the sheath 2 as shown in FIG. guide 84 have the function of facilitating the assembly, said cutout also defining a protruding lip 85 intended to engage during engagement with a slot 86 of the cross member 81 to ensure the locking of the column 82 with said crossbar 81.

Of course, other modes of implementation could have been envisaged by those skilled in the art without departing from the scope of the invention defined by the claims below.
