Description

The invention relates to a suspended sign.

  Temporary and main events

  The exhibitions also use a large number of

  hanging lords. Their number and dimensions vary with the nature, surfaces and volumes of

  occupied buildings, but as with any installation technique

  temporary installation, the criteria for an improved material

  rator are the speed of implementation and disassembly, the lightness and reduced volume as well as the ease of

  transport, storage and reuse.

  The current increase in the occupation of exhibition buildings due to an increasingly accelerated rotation of exhibitions and, therefore, decreases in installation times, leads to the search for techniques for producing suspended signs which present the above criteria to the highest degree. Indeed, when the time separating two exhibitions is reduced, moving, dismantling, reassembly and installation operations create a

  congestion such that it becomes very difficult and irration-

  nel to circulate in the aisles with lifting machines

  and large signs.

  We also know signs made of fabric and whose upper edge, provided with a hem, is placed on a horizontal tube ensuring

26 10127

  the suspension of the sign. In this case, the lower edge of the sign is generally also provided with a hem which receives a second tube or a horizontal bar ensuring the ballasting of the fabric and its maintenance in the vertical stretched state.

  The use of fabrics for the realization

  sation of the signs certainly allows to reduce the weight and the volume, but the signs thus produced always pose problems when one wishes to transport them and put them in place in the superstructures of an exhibition hall. Indeed, if these signs are rolled to be transported, the rolling operation, which is moreover very difficult to execute correctly, creates different tensions, due to differences in radius and elasticity, which deteriorate the letters by pleating them or by taking them off, which prohibits their use according to the technique

  of a blind rolled up on a horizontal axis.

  It follows that the current fabric signs must be executed stretched vertically in large workshops and that they must be transported

flat.

  The object of the present invention is in particular to remedy these drawbacks and to this end relates to a suspended sign consisting of a sheet of flexible material provided, on at least one of its faces, with inscriptions constituting the sign itself, sign characterized in that the sheet is provided with preferential fold lines established along lines parallel to the upper edge of suspension of the sign, the structure and / or the thickness of this sheet, outside the fold lines, being such that this sheet has an outfit suitable for promoting

  folding it along these preferential folding lines.

  According to another characteristic of the invention, the preferential fold lines consist of folds marked permanently

by creasing.

  According to another characteristic of the

  note, the fold lines consist of lines at the height of which the thickness of the sheet

is decreased.

  According to another characteristic of the

  Note, the sheet is made up of a fabric and the preferential fold lines are produced by local removal of the weft or warp threads from the fabric. According to another characteristic of the invention, the fold lines are determined by a relative modification of the flexibility of the sheet between the fold lines and the other parts of the sheet.

  According to another characteristic of the

  vention, the folds of the leaf are alternately directed

  towards both sides to ensure its

zigzag folding.

  According to another characteristic of the

  vention, the flexible sheet of the sign is made up

  by a non-woven material such as paper.

  The invention is shown by way of non-limiting example in the accompanying drawings in which: - Figure 1 is a schematic perspective view, in the deployed state, of a first embodiment of the suspended sign according to the invention; - Figures 2 and 3 are partial sectional views illustrating two methods of obtaining the preferred fold lines of the sign; - Figure 4 shows, in section, a method of stiffening the upper edge of the sign suspension;

  - Figure 5 shows, in diagrammatic section

  tick, another embodiment of the stiffening of the upper edge of the sign as well as a method of suspending this sign; - Figure 6 shows, in partial perspective, an embodiment of the suspended sign, foldable in a zigzag; - Figure 7 shows, schematically, a foldable sign by rolling flat; - Figure 8 shows another embodiment of the sign; - Figure 9 is a partial perspective view of an embodiment of a double sign. The present invention therefore aims to achieve a low weight sign, which is a realization, assembly and disassembly quick and easy, which can be placed automatically, that is to say say without special precautions, in its folded storage position, allowing its storage

and its transport.

  Also, because of its constructive features, this sign can be made of

  large dimensions, without any inconvenience

  notables concerning its cost price, its

  handling, storage and transport.

  According to the invention, the support material of the sign is constituted by a flexible sheet 1, which is provided on one of its faces, inscriptions 2 constituting the sign itself, this flexible sheet 1 having lines of preferential folding 3

  established parallel to the upper edge 4 of the sign.

  The structure and / or the thickness of this sheet with respect to those of the fold lines, is such that it has a behavior suitable for promoting the folding of the sheet along these preferred lines, in particular for the transport of the sign. made to her

place of use.

  Because of this combination of the preferential fold lines parallel to the upper edge and of the clean behavior of the material constituting this sheet, an automatic folding of the flexible sheet is obtained exclusively along these preferential fold lines, without the worker having to to pay particular attention to

to this folding operation.

  The upper edge 4 of the sign, which is provided with suspension means 5, also comprises

  a stiffening rod 6 intended to maintain recti-

  line the upper edge 4 of the sign when it is deployed, as well as to facilitate the folding operation for the storage of the sign. Indeed, during this storage operation, a single worker or a maximum of two if the sign is very long, is sufficient to

  fold the sign. In this case, the-

  check by holding the stiffened upper edge 4 of the

  seigne automatically folds along the preferential lines 3 by lowering the upper edge and moving it alternately in one direction and in the other to help the formation of the succession of

folds.

  The material constituting the flexible sheet may be a fabric, plasticized or not, or a sheet of plastic, but it will preferably be produced by a sheet of non-woven material, of the paper type, which not only makes it possible to obtain a sign. low weight and low cost, but still easily obtain preferential fold lines as well as a clean hold of this sheet of paper by choosing its thickness and structure according to the desired dimensions of the sign and the distance of lines of

preferential folding adjacent.

  Also, the use of a non-woven paper-like material to make this sign

  gives it, given its thickness, a semi

  transparency which due to the ambient lighting of an exhibition hall or other, gives this sheet a

  certain brightness improving the visibility of the ins-

  opaque and colored scratches on the sign; Also, this sheet of nonwoven material will preferably be made with inclusions of long fibers (a few centimeters) and, in particular of glass fibers, in order to improve the clean hold of the sheet of flexible material to prevent it from folding back.

  other than the preferred fold lines

  planned profitability, as well as to increase its resistance to tearing. This inclusion of fibers distributed in the material constituting the sheet will also give it, by transparency, a moire appearance enhancing the sign.

  by its contrast with the inscriptions.

  The fold lines can be determined by modifying the flexibility of the sheet at the height of the folds relative to the rest of the sheet. Thus, it could be envisaged either to increase the flexibility of the sheet at the height of the fold lines, for example by

  a chemical attack process, that is to reduce the

  leaf thickness outside the fold lines, for example

  example by coating with a resin.

  The preferential fold lines will however preferably be constituted by folds marked permanently by creasing and, in this case, the sign once deployed may reveal small projecting beaks 31 at the height of the fold lines, without harming the flatness of the suspended sign taken as a whole and this due to the

  clean keeping of the material constituting the sheet.

26 10127

  This flatness of the sign could be further improved by providing a ballast rod or

  similar 7 along the lower edge of the sign.

  In the embodiment of FIG. 1, the lines, of folding 3 obtained by creasing, are directed alternately towards one and the other sides of the sheet, in order to allow its zigzag folding

during its storage.

  According to the nature of the material constituting the flexible sheet of the sign, as well as according to the dimensions of this sign, the preferential fold lines can also be obtained in the manner shown in FIG. 2, in which these lines 8 are obtained by a local decrease of

  the thickness of the material constituting the sheet.

  Also, as shown in Figure 3, this local crushing can be combined with a crease marking by creasing, as shown in 9 on

Figure 3.

  According to the embodiment of Figures 1 to 3, the marking of the folds of the sheet constituting the sign will be obtained quickly and easily with a suitable tool 5 by continuously scrolling the

  sheet material between crushing rollers.

  In the case where the sheet of flexible material consists of a fabric, preferably plasticized, the preferential fold lines can be obtained in a simple manner by providing for the elimination of a few warp or weft threads, at the height of these fold lines , to modify the behavior of the sheet in these areas. Also, this removal of warp threads

  or weft to determine the preferred fold lines

  cost-effective, could be combined with a marking of these

  lines by creasing folds and / or crushing.

  The stiffening of the upper edge 4 of suspension of the sign can be obtained by gluing or stapling a strip 6, as shown in Figure 1, or by folding the upper edge of this sheet 1 (see Figure 6) so as to form several folds or flaps 10 which are joined to each other by sewing or gluing, so that this extra thickness gives sufficient rigidity to the upper edge of the sheet, in order to maintain the linearity of the upper edge of the sign when

it is suspended.

  This suspension could be ensured by wires or strings, knotted right through the upper edge of the sign or even using a stretched cable passed through a hem provided on the upper edge

of the brand.

  However, in accordance with the invention, provision has been made to make perforations along the upper edge 4 of the sign, these perforations 11 being of

  preferably made through the stiffening rod

wise from the edge of the sheet 1.

  The suspension of the sign is then ensured by double "S" hooks 12, one of the loops of which is passed through the perforations 11 and the other of which is hooked into the groove 131 of a profile 13 permanently fixed, in the upper part, where it should be

suspended the sign.

  This arrangement will allow a quick and easy hanging of the sign, without being hampered by the number and the position of the hooks 12, since these automatically place themselves in the desired position in

the groove 131 of the profile 13.

  The inscriptions on the sign will be printed or painted directly on the flexible sheet of

26 0127

  support but they will preferably be constituted by letters cut from a flexible and opaque material which is adhesive on one of its faces, so as to be able to stick these inscriptions, by their adhesive face, on one of the faces of the flexible sheet. Such cut adhesive inscriptions, for example plastic, are particularly suitable for the implementation of a sheet 1 of non-woven material of the paper type, taking into account the adhesion

  that it is possible to obtain between these two materials.

  If this is deemed desirable (see FIG. 6) the inscriptions 14 of the sign which are cut and glued on one of the faces of the flexible sheet 15, will be interrupted at 16 at the height of the preferential fold lines 17 of the sheet 15 , this in order to avoid a start of take-off of the inscription up to the lines 17 after several deployment operations and

folding of the sign.

  In the embodiment of Figure 1,

  the permanent folds 3 of the sheet are directed alter-

  natively towards both sides of the sheet 1 to ensure its zigzag folding. However, in certain cases, it will be considered desirable to direct all the folds of a flexible sheet which should constitute the sign towards

  one side of the sheet to allow its storage

  by rolling flat, as shown in

Figure 7.

  This arrangement is, in certain cases, preferable to the zigzag folding because by arranging the face of the sign provided with inscriptions inside the folds, one completely protects the visible face of the sign

and, in particular, these inscriptions.

  In this case, the fold lines 18 will be made at different spacings, increasingly larger, to allow the flat rolling of the sheet.

of flexible material.

  This different spacing of the fold lines could also be envisaged according to the dimensions of the inscriptions which must be carried on the sign and, also, according to the nature of the material which

constitutes these inscriptions.

  Thus, if one wishes to avoid folding the sign up to the inscriptions, the position and

  the spacing of the fold lines can be determined

  mined depending on the position and height of

  inscriptions to be fixed on the support sheet.

  For example, as shown in FIG. 8, the sheet 20 could include preferential fold lines 21 on the one hand, and 22 on the other hand, which are produced at a spacing slightly greater than standard inscription dimensions so that the fold lines are outside of these inscriptions and so that they also constitute lines of

  marking for the positioning of these inscriptions.

  As already indicated, the sheet of flexible material constituting the support of the sign will preferably be a semi-transparent material. The disadvantage of such a construction however lies in the fact that the inscription which is worn on one side can be slightly visible on the opposite side, which limits the possibility of making inscriptions on both sides. To make this inscription on both sides of the sign without being hindered by the semi-transparency of the sheet of support material, it was then planned, in accordance with the invention, to use a sheet

  double 23, 24. In this case, the two sheets are dis-

  laid parallel to each other at a distance from each other and are each provided with fold lines 25, preferably situated at the same height. Because of this arrangement, the spacing between the two support sheets 23, 24 makes it possible to make invisible, on one of the faces of the sign, the inscriptions which are worn on the other face, without reducing the 'luminosity effect of the sign resulting from its semitransparent material. The spacing of the two sheets 23, 24 of flexible material, will preferably be obtained by a strip 26 disposed along the upper edge of the sign and constituting both the stiffening strip and the spacer of the two sheets. These two sheets 23, 24 are fixed by gluing, stapling or any other means on either side of this

wand 26.

  Also, in this case, the lower edges of each flexible sheet are provided with a ballast rod 27 cooperating with the flatness of the two faces of the sign.

  According to another embodiment not shown

  felt, the same result can be obtained by making the sign in the form of a flattened bracelet whose

  two flat surfaces form the useful faces of the

  seigne, the upper end and the lower end

  of this sign being strung on bars

  one, the stiffening and suspension bar

the other the ballast bar.
