Definitions

  • the present invention relates to a display panel, of substantially rigid type, having a front intended to receive a poster by gluing using a reversible glue and to allow the poster to take off using a solvent for said glue. , as well as a method of fitting and removing a poster pasted by means of a reversible adhesive on the front of such a panel, and a support for at least one such panel when the latter has two straight edges, mutually parallel, intended to be oriented substantially vertically.
  • the present invention relates more particularly to outdoor display, it being understood that it could also find its application in sheltered display.
  • a widely used display technique consists of manually sticking a paper poster, possibly formed of a juxtaposition of several elements, on a rigid and heavy panel, for example made of sheet steel, wood or more rarely polyester, placed irremovable on the exhibition site.
  • an adhesive is applied, generally consisting of a colloidal aqueous solution of starch or cellulose derivatives, either to the back of the poster which is then placed on the panel using a brush, either on the panel itself before applying the poster on it.
  • This known display technique lends itself to the installation of posters of any dimension on supports of any dimension taking into account the possibility of juxtaposing several elements constituting the poster and ensures between the poster and the panel a sufficiently intimate connection for that the latter communicates to the poster its own characteristics of rigidity and mechanical strength, that is to say an outfit that the poster does not have in itself, but it causes nuisances inherent in the use in situ of liquid glue, of which it is difficult to avoid splashes and spills on the ground, the need to use a scraping to remove a poster before putting another, and the production of waste paper resulting from such scraping.
  • this technique has the disadvantage of prolonged exposure of operators weather and the dangers of traffic, and that of prolonged occupation of the public highway by operators and their parked vehicle.
  • FR-A-2 087 730 has proposed a certain number of provisions, some of which relate to the structure of the poster itself. same and another of which consists in providing in the panel, also produced in this case in the form of a rigid plate, a multitude of holes making it possible to soak a component of the poster through the panel and through the glue, in order to then be able to detach the poster in one piece. This avoids the drawbacks inherent in scraping, namely the long and tedious nature of such scraping and the production of paper waste in abundance.
  • the plate retains a significant weight which makes the manipulations required in particular by the soaking difficult, namely its disassembly with respect to its support, its handling to the place of soaking, then during this dipping itself and on the return to the support, then reassembly on this support, unless often limiting the dimensions of the plate in plan, that is to say the dimensions of its front and back .
  • French patent application No. 2 625 019 proposes to use as support for display panels two substantially vertical slides, mutually integral, placed face to face to receive two rectilinear edges, mutually parallel, of the panel , these two slides being closed at the bottom and open at the top so as to allow the installation and removal of a panel by means of a crane, from the top of the support.
  • This technique allows the panels to be quickly exchanged on the same support, that is to say to limit the exposure of operators to bad weather and to the dangers of automobile traffic, and to carry out the operations of sticking and taking off of the posters in the workshop, under optimal conditions.
  • it requires the use of a crane truck which, during the operation of exchanging a display panel on a support, constitutes an obstacle to automobile traffic.
  • the need to intervene from the top of the support to carry out the installation and removal of a panel requires intervention at significant heights, in delicate conditions of stability and precision and with the imperative of having the necessary clearance above the support.
  • Weight requirements of the glass facade also limit this format, it being understood that the absence of any panel ensuring cohesion to the poster generally made of paper does not allow the latter to be exposed directly to the weather and therefore imposes the use of such a glass facade, even if it is also true that the glass facade has the disadvantage of detracting from the visual rendering of the poster because of the risk of parasitic reflections and the presence of raindrops on the front of this glass facade, or condensation on the back of it.
  • this technique requires a prolonged presence of operators, thus exposed to prolonged exposure to weather and traffic and occupying public roads for a prolonged period, in particular by means of their parked vehicle.
  • the object of the present invention is to propose a new display technique overcoming these drawbacks.
  • the present invention provides a display panel, of substantially rigid type, having a front intended to receive a poster by gluing by means of a reversible glue and to authorize the take-off of the poster by means of a solvent for said adhesive, said panel also having a multitude of holes passing through it from front to back in a manner distributed substantially over all of the respective expanses of the latter so as to make it permeable to said adhesive and to said solvent between its front and its back, as it follows from the teachings of French patent N ° 2,087,730, this panel being characterized in that it is formed of means in themselves flexible, isotropic and substantially inextensible, constituting its front and back as well as said holes , and of a rigid frame which borders said means in themselves flexible on all sides and whose said means in themselves flexible are made integral, in a substantially continuous manner e, in the stretched state.
  • the panel can be formed from a homogeneous, flexible, isotropic, substantially inextensible sheet, provided with a multitude of perforations, each of which constitutes one of said holes, and with a rigid frame which borders said sheet on all sides and of which said sheet is made integral, in a substantially continuous manner, in the stretched state, or else of a flexible, isotropic, substantially inextensible assembly, of flexible, substantially inextensible, intertwined threads defining between them a multitude of meshes each of which constitutes the 'one of said holes, and a rigid frame which borders said assembly on all sides and of which said assembly is made integral, substantially continuously, in the stretched state.
  • Said yarns may be metallic, or of the textile type, chosen from natural yarns and synthetic yarns, preferably monofilaments; in particular, good results have been obtained in tests by making the panel from a taffeta of monofilament polyester yarns with a diameter of between 90 and 100 micrometers, at a rate of approximately 34 threads per linear centimeter, glued to the using a single or two-component polyurethane adhesive on a frame constructed from welded aluminum tubes, and using an aqueous solution, between 5 and 15% of dry extract, for gluing the poster to the panel, partially hydraulic polyvinyl alcohol including a non-ionic antifoam, a preservative and a slip agent, the resistance of the assembly to water can be adjusted to the desired level by incorporation of monoaldehyl or dialdehyde, or alternatively of amnoplast and takeoff of the poster being carried out by immersion in a non-ionic and non-foaming detergent bath and rinsing with a pressurized water
  • a panel according to the invention can be much lighter while having the required rigidity and that, in addition, the means constituting its front and back, chosen independently of any question of rigidity, can have both a much smaller thickness and a much higher hole density, expressed in terms of the cumulative area of the holes in comparison with the area of the front , in particular, which considerably improves the permeability of the panel to the adhesive and to a solvent thereof; thus, according to a preferred embodiment, the holes of the panel have at least at the level of the front thereof a cumulative area of the order of 40% to 50% of the area of this front, approximately, these figures being indicated by way of nonlimiting example.
  • the increased permeability of the panel to the adhesive makes it easier to anchor the latter, that is to say also the anchoring of the poster, to the panel, and the increased permeability of the latter to a solvent. glue allows much easier and faster takeoffs by intervention with solvent from the back of the panel.
  • the solvent applied for the purpose of taking off the display can consist simply of water, optionally added with a detergent, if the adhesive used is soluble in water after drying.
  • a particularly effective mutual anchoring of the poster and the panel is thus obtained, without taking off the poster presenting great difficulties even in the case of a water-soluble adhesive since it is possible to project this water and any pressurized additives on the back of the panel to dissolve the adhesive when desired, even if it has been dosed so as to withstand bad weather which only involves low water spray pressures; in addition, when it is planned to practice bonding or take-off in the workshop, take-off can be practiced by dipping in a solvent bath.
  • the support may comprise at least a set of two substantially horizontal slideways, mutually integral, having substantially horizontally a dimension substantially equal to said determined length and defining towards each other a respective substantially horizontal channel, having a U-section in any vertical plane to receive substantially horizontal sliding l 'one, respectively, of said edges;
  • the realization of the panel in accordance with the present invention makes it possible to lighten it considerably and, consequently, to make it more manageable.
  • a display panel according to the invention having two rectilinear edges, mutually parallel, of determined length, intended to be substantially vertically oriented, a support comprising two rectilinear edges, mutually parallel, of determined length, intended to be oriented substantially vertically, said support comprising at least one set of two substantially vertical slides, mutually integral, having substantially vertically a dimension substantially equal to said determined length and defining a respective channel towards each other substantially vertical having a U-shaped section in any horizontal plane to receive the substantially vertical sliding, one respective of said edges, providing that said channels are open upwards to allow the exchange of panels but closed downwards for prevent the fall of these.
  • the present invention provides a simple and economical variant of such a support, characterized in that said channels are open downwards at the level of respective lower ends of said slides to receive the substantially vertical sliding of said edges, and in that means are provided for sealing said lower end of at least one of said slideways, said shutter means being mounted movable relative to said slideways between a shutter position of said lower end and a release position thereof and capable of being temporarily immobilized relative to to said slides at least in said closed position of said lower end.
  • Said shutter means may advantageously include a flat frame articulated around a substantially horizontal axis at the respective upper ends of said rails, between a substantially vertical orientation in which it frames said rails and has opposite lower ends thereof. ci, under said lower ends, a substantially horizontal rim closing the latter down, and an oblique orientation relative to the vertical and in which said rim releases said ends lower downwards, said frame being able to be immobilized temporarily with respect to said slides at least in said substantially vertical orientation, so as to be aesthetic, efficient and simple to produce.
  • Such a support can be mounted movable relative to the ground on said specifically provided or pre-existing support means, to facilitate the introduction of a panel between the slides or the extraction of this panel out of the slides, but, so particularly simple, it is preferably intended to be placed in a fixed position above a floor, in which case said specifically provided or preexisting support means provide rigid support for said slides relative to said floor and preserve between said respective lower ends slides and the ground a distance which, measured substantially vertically, is at least equal to said determined length.
  • the same support can receive a single panel according to the invention, or receive several; for example, according to a preferred embodiment, it comprises two copies of said set of two slides and respective mutually independent closure means, each slide of one of the games being juxtaposed with a respective slide of the other of said games, to support two display panels facing back against back, each of the two display panels protecting the back of the other panel from view and weather.
