Abstract

The poster fastening system consists of a surround made from retaining members (31) with studs (211) to engage with perforations in the edges of a poster, and fasteners (41) to fix the retaining members to upper and lower cross-pieces (21) of a frame on the supporting surface (1). The components of the system can be made e.g. by moulding and/or extrusion from aluminium, metal alloy or composition material.

Description

The invention relates to the field of display. More specifically,

  the invention relates to a display device capable of being adapted to any

  support, fixed or mobile, such as a wall or a vehicle.

  For the fixing of the posters on a support, one distinguishes essentially

  two techniques: pasted posters and non-pasted posters.

  In addition to the problems with the adhesion over time, in particular due to bad weather, the fixing of the posters by gluing on a support generates

  long intervention times, both during gluing and take-off.

  To protect the poster from bad weather, the poster can be commonly placed in a box closed by a transparent surface. This technique causes difficulties for large display formats, namely to manufacture

  such boxes, either when handling them to place or replace a poster.

  Fixing systems by hanging the poster allow to circumvent the problems linked to the use of glue. Conventionally, the poster has perforations regularly distributed over at least one of its edges, these perforations being intended to cooperate with lugs or other hooks

secured to the support.

  Whether on a fixed or mobile support, these systems do not allow the poster to be powered up enough to obtain good flatness.

  At the same time, the hanging means are fairly basic and

  do not exclude the possibility of unexpected or ill-intentioned stalls, the maintenance of the poster on its support is not sufficiently rigid and / or

  protected from manipulation by unauthorized persons.

  Consequently, the object of the invention is in particular to alleviate these

disadvantages of the prior art.

  In general, the object of the invention is in particular to provide a device for fixing posters that is reliable and capable of being adapted to any

  support, fixed or mobile, exposed to the weather or not.

2 2811460

  More specifically, the invention aims to propose a device which allows the poster to be tensioned in different directions, and

  preferably in all directions.

  Another object of the invention is to provide a device in which the attachment means are protected from the weather. The invention also aims to prohibit direct access to the attachment means by unauthorized persons, in particular for the purpose of flying

the poster displayed.

  Yet another objective of the invention is to propose a device for hanging posters which can be adapted according to the needs of placing under

poster tension.

  Another object of the invention is to propose a device for hanging posters which can be easily produced for all poster dimensions, including

including large formats.

  The invention also aims to provide such a device which is

  simple and efficient, and which can be produced economically.

  Another objective of the invention is to propose an assembly method

  of such a device which can be carried out by a non-specialized person.

  These objectives, as well as others which will appear subsequently, are achieved using a device for fixing posters on any support, of the type comprising a plurality of pins provided on said support or on at least a cross member fixed to said support, said pins being intended to cooperate with perforations formed in at least one edge of a poster. According to the invention, the device comprises at least one holding part cooperating with said lugs and intended to press the perforated edge of said poster against said support

or said crosspiece.

  Thus, an effective means is obtained for maintaining the poster on the support, in particular preventing the poster from coming off the pins under the action of the

  wind or air intake caused by the movement of a vehicle.

3 2811460

  According to an advantageous solution, the device comprises means for locking said retaining piece on said support or said crosspiece. Of

  this way, we secure the exhibition of the poster against theft for example.

  Preferably, said retaining part has a gutter pierced with orifices for the passage of said lugs. It is thus possible to provide a piece of

  support whose length covers all of the pins.

  Advantageously, said locking means are slidably mounted in said gutter. In this case, said locking means comprise at least one profile having at least one opening, for the passage of at least one of said lugs, said opening communicating with a trough bordered by at least one inclined ramp forming a cam so that the movement of said chute on said lug leads to blockage or

  release of said locking means.

  The holding pieces and the locking means can be designed and manufactured separately. In order to reduce the number of parts and to facilitate assembly, said locking means are integral with said holding part. In order to obtain good flatness of the displayed poster, additional means can be provided for pressing the poster against the support, near the edges of the poster. To meet this objective, said retaining piece comprises a first inclined plane intended to fold down said poster

against said support.

  According to a preferred solution, said retaining part has at its periphery a second inclined plane. This protects the periphery of the device

  against various splashes of rainwater or small objects.

  Advantageously, the device comprises at least one joint fitted between said retaining part and said crosspiece. We can in this way keep the poster resting against the second inclined plane, to avoid the border of

faseyer's poster.

4 2811460

  In particular when the poster must be perfectly stretched, means can be provided to firmly hold the border of the poster between each of the pins. Thus, preferably, said crosspiece comprises a groove intended to cooperate with means projecting from said holding part, for maintaining said poster. In order to prevent easy manipulation of the locking means by unauthorized persons, the device comprises finishing pieces intended to be secured to the ends of said crosspiece, said finishing pieces at least partially covering the assembly formed by at least part of said holding part and at least part of said locking means. Depending on the case, that is to say depending on the level of flatness requested and / or the place of exposure more or less subject to bad weather, the poster needs to be more or less stretched. Thus, according to a preferred solution, the device comprises a high cross member and a low cross member. We can thus stretch the poster in its height. According to another preferred solution, the device comprises a set of crosspieces forming a frame. In this way, the poster can be stretched in all

directions.

  The invention also relates to a method of mounting a device for hanging posters, comprising the steps consisting in - securing at least one cross member or one frame to said support; - Set up a poster by matching the perforations it carries with the pins of said crosspiece or said frame - press said poster against said crosspiece or said frame with at least one holding piece; lock said one or more holding pieces with said cross member or

  said frame thanks to said locking means.

  Other characteristics and advantages of the invention will appear more

  clearly on reading the following description of an embodiment

2811460

  preferred of the invention, given by way of illustrative and nonlimiting example, and of the appended drawings among which: - Figure 1 illustrates, in a cross section, the device according to the invention in the assembled state - Figure 2a shows in a cross section, a crosspiece according to the invention, Figure 2b illustrating a lug of the type of those reported on the crosspiece or the support Figure 3 illustrates a holding piece according to the invention seen in a cross section - the figures 4a to 4f illustrating the locking means according to different sectional and perspective views; - Figures 5a to 5f illustrating a finishing piece according to different views in section and in perspective - Figures 6a and 6b give a partial view of the device according to the invention in the assembled state with a finishing piece, respectively from the side and in perspective; - Figure 7 shows the device according to the invention, mounted on a vehicle. The general principle of the invention therefore rests on an assembly of means whose functions complement each other to firmly hold the poster against a support, to protect it from the action of bad weather, to stretch it in different directions and to avoid that it is not easily removed from the

device in order to steal it.

  In Figure 1, there is shown a device for hanging a

  poster 10 according to the invention, in the assembled state.

  The poster 10 is hung on a cross member 21 provided with a plurality of lugs 211 (FIG. 2b) introduced into the perforations (not shown)

  provided for this purpose on at least one of the edges of the poster.

  The pins 211 are regularly distributed, on the crosspiece 21 or the support 1, being spaced from each other by 10 to 20 cm, their spacing

6 2811460

  anyway corresponding to that of the perforations of the poster 10, or vice versa. The poster 10 can be presented in one piece or be reconstructed using several strips or leaves. In this case, preferably, the strips overlap so that, in particular for posters on a mobile support, the rear edge of a strip partially covers the front edge of the

  adjacent strip, in the direction of movement of the support.

  The cross member 21 is intended to be fixed on any flat support 1 (represented by dotted lines) ,; alternatively, the pins 211 can be directly secured to the support 1. Most often, however, especially when the poster is exposed on the walls of a vehicle, recourse will be had to

sleepers 21.

  The device further comprises a holding piece 31 intended to cooperate with the cross member 21 to increase the holding of the poster 10, the latter being trapped between the two pieces 21 and 31. So as to ensure firm holding between the pins 211, the cross member has a gutter 212 (FIG. 2a) while the retaining part 31 has a protruding part 311 (FIG. 3), the gutter 212 and the element 311 both having a substantially triangular section. In this way, once the device has been assembled, the holding piece 31 forces the poster 10 to follow the shape of the gutter 212

  and holds it firmly in place, including when it is stretched.

  The holding element 31 has a gutter 312 pierced with orifices 313 regularly distributed so as to correspond with the arrangement of the lugs 211

  carried by the cross member 21 or the support 10.

  The holding element 31 is extended by a first inclined plane 314, intended to fold the poster 10 onto the support 1. The poster is thus brought to bear against the support 1, or at least in a plane very close to that of the support. Opposite the first inclined plane 314, the holding part 31 has a second inclined plane 315 which protects the periphery of the device against

7 2811460

  various splashes of rain water or small objects likely to deteriorate

  term the poster or the device itself.

  The cross member 21 comprises a chute 213, the walls of which each integrate a groove 214, 215 forming a housing intended to receive the base of a seal 11. This seal is dimensioned so that it fits between the cross member 21 and the holding part 31. The end of the poster 10 is thus pressed against

  the holding part 31, preventing it from faseying.

  Bores can be provided in the trough 213 and in the gutter 216 for the passage of fastening means, for example by screwing, of the

cross member 21 on support 1.

  Locking means 41 cooperate with the lugs 211 to firmly hold the part 31 against the cross-member 21, the poster 10 being jammed

between the two.

  The locking means 41 are designed to operate by sliding in the gutter 312 of the holding part as will

  now be explained using Figures 4a to 4f.

  The locking means 41 are profiles, the section of which forms a

  U whose uprights are folded inwards to delimit a slide 411.

  The latter has on each of its edges at least one notch 412,

  forming an opening for the passage of the head 2111 of a lug 211.

  Each notch 212 communicates with an inclined ramp 414

  integrated into each blank 413 of the slide 411.

  During assembly, the locking means 41 are introduced into the gutter 312 of the holding part 31, positioned so that the pins 211 penetrate inside the locking means through the openings 412. The means of sliding are then slid locking 41 in the gutter 312, so that the head 2111 of the lugs 211 move along the ramps 414 forming

  cam, to a locking position.

  The device described here uses a holding part 31 and locking means 41 designed separately. However, it is possible

8 2811460

  to combine their function on a single profiled part alternately having the protruding means 311 and the locking means 41

one next to the other.

  In Figures 5a to 5f, there is shown a finishing part 51 intended to be attached to the device. The part 51 presented by way of example forms an angle and is therefore particularly intended for an application of the invention according to which the

  sleepers 21 form a frame around the poster.

  The part 51 has edges 511 and 512 shaped to conform respectively to the shape of the inclined planes 315 and 314 of the holding part 31,

  by covering me at least partially.

  A groove 513 is provided to contain the part of the means of

  locking 41 projecting from the gutter 312 of the holding part 31.

  Bores 514 are provided for the passage of fastening means, for example screws, key part 51 for example on the locking means 41, the latter being then fixedly held in the locked position. The part 51 as described is therefore attached to each angle of the frame device. It can also be considered itself in the form

of a monobloc frame.

  In the case where a single cross is used, or in the case where two cross are used to put the poster in vertical tension, the part 51 can then be adapted to form a cover at the end of the cross according to the same principle. If only one crosspiece (21) is used, the poster (10) can be ballasted in its lower part in order to give it a taut appearance. Preferably, to stretch the poster (10) along its vertical axis, a high cross member and a low cross member will be attached to the support, separated by a distance appropriate to the height of the poster (10). To stretch the poster in all directions, we will use

  preferably the device according to the invention shaped in a frame.

9 2811460

  Figures 6a and 6b illustrate the device in the assembled state, the part of

  finish 51 covering the holding pieces 31 and the locking means 41.

  The poster is thus kept firmly stretched in all directions, the disassembly of the different parts being necessary to access the poster, thus dissuading any attempt to steal the poster. All the parts of the device can be produced by molding and / or

  extrusion, in aluminum, metal alloy or composite material.

  This type of manufacturing as well as the design of the parts

  allow the application of the device to different poster dimensions.

  The invention can thus be envisaged on a wall support for small or large posters, or on vehicles as shown in FIG. 7 according to which the device shaped as frame 71 can cover all or part of the

enclosure walls.

  The method of mounting a device for hanging posters according to

  the invention notably comprises the following steps.

  At least one cross member 21 or a frame 71 profiled according to the same principle as the cross members 21 is fixed on the support 1. A poster 10 is put in place by matching the perforations which it carries with the pins 211 of the

cross 21 or frame 71.

  The poster 10 is then pressed against the cross member 21 or the frame 71 with at least one retaining piece 31. The retaining piece or pieces 31 are then secured to said cross member 21 or said frame 71 thanks to said means of

lock 41.

  Finishing pieces 51 are then added at least on each end of the crosspieces 21 or at least at each corner of the frame 71 and are there

  joined together for example by screwing.

  The assembly process described above can be carried out

  simply, without complicated tools, by non-specialized personnel.
