Abstract
Description
L'invention se rapporte à un dispositif de présentation d'au moins un document photographique en feuille. The invention relates to a device for presenting at least one photographic document in sheet form.
L'invention se rapporte également au procédé de réalisation du dispositif. The invention also relates to the method for producing the device.
Pour la présentation de documents photographiques consistant en feuille opaque présentant, sur l'une de ses faces, une image observable par réflexion, on utilise classiquement un dispositif qui comprend essentiellement
- un élément rigide généralement plat, de dimensions au moins suffisantes pour recevoir la feuille photographique par sa face opposée à celle constituant la face observable,
- un moyen de maintien du document sur ledit élément rigide,
- un moyen d'orientation de l'élément rigide et de maintien de cette orientation par rapport à un support.For the presentation of photographic documents consisting of an opaque sheet having, on one of its faces, an image observable by reflection, a device is conventionally used which essentially comprises
- a generally flat rigid element, of dimensions at least sufficient to receive the photographic sheet by its face opposite to that constituting the observable face,
a means for holding the document on said rigid element,
- A means of orienting the rigid element and of maintaining this orientation relative to a support.
Ce dernier moyen consiste généralement en un piétement tel une face d'appui de l'élément rigide et/ou en un organe de suspension à un crochet présenté en saillie sur une surface verticale telle un mur. The latter means generally consists of a base such as a bearing face of the rigid element and / or a suspension member to a hook projecting from a vertical surface such as a wall.
Les dispositifs les plus simples du type précité comprennent un élément rigide qui consiste en une plaque de matériau et un moyen de maintien constitué par une couche et/ou une feuille de matière adhésive interposée entre le document et la face porteuse de l'élément rigide. The simplest devices of the aforementioned type comprise a rigid element which consists of a plate of material and a holding means constituted by a layer and / or a sheet of adhesive material interposed between the document and the carrying face of the rigid element.
Ces dispositifs de présentation classiques permettent surtout à préserver la planéité du document à présenter. These conventional presentation devices allow above all to preserve the flatness of the document to be presented.
Pour souligner le document et/ou le mettre en valeur dans l'environnement qui le reçoit, il est connu d'adjoindre un cadre autour de l'élément rigide. To emphasize the document and / or enhance it in the environment that receives it, it is known to add a frame around the rigid element.
Egalement pour préserver le document de dépôts, notamment de particules en suspension dans l'air, il est connu de placer devant et contre lui, une feuille de matériau transparent, telle une feuille de verre. Also to preserve the document of deposits, in particular of particles in suspension in the air, it is known to place in front of and against it, a sheet of transparent material, such as a sheet of glass.
L'esthétique de ces dispositifs est dans certains cas incontestable mais aussi recherchée qu'elle soit, elle n'enlève pas au dispositif son caractère conventionnel. The aesthetics of these devices is in some cases incontestable but also sought after as it is, it does not detract from the device its conventional character.
Pour tenter de remédier à cet inconvénient, il est connu (FR-A-2.071 .407) d'emprisonner le document photographique observable par réflexion dans un matériau transparent constituant finalement un bloc généralerent paral lélépi pédique de dimensions supérieures audit document et dont une des faces réalise une face d'appui sur un support. In an attempt to remedy this drawback, it is known (FR-A-2,071,407) to imprison the photographic document observable by reflection in a transparent material finally constituting a general block paral the pedicel of dimensions greater than said document and one of which faces creates a bearing face on a support.
L'effet esthétique obtenu est intéressant niais le document opaque constitue une solution de continuité d'aspect qui cependant altère ledit effet esthétique essentiellement lorsque l'angle d'incidence d'observation dudit document s'écarte de la normale à ce document. The aesthetic effect obtained is interesting but the opaque document constitutes a solution of continuity of appearance which however alters said aesthetic effect essentially when the angle of incidence of observation of said document deviates from normal to this document.
Un résultat que l'invention vise à obtenir est un dispositif du type précité et dont le document photographique présenté semble avoir été constitué au coeur rïrême du bloc de matériau transparent. One result which the invention aims to obtain is a device of the aforementioned type and the photographic document of which appears to have been made up at the very heart of the block of transparent material.
A cet effet l'invention a pour objet un dispositif de présentation d'un document photographique en feuille, dans un bloc de matériau transparent, lequel dispositif est caractérisé en ce que, selon l'invention, au lieu d'être observable par réflexion, c'est à dire au lieu d'être constitué sur une feuille opaque, le document photographique utilisé pour constituer le dispositif est du type observable par transparence, c'est à dire consiste en une image realisee sur une feuille transparente. To this end, the subject of the invention is a device for presenting a photographic document in sheet form, in a block of transparent material, which device is characterized in that, according to the invention, instead of being observable by reflection, that is to say instead of being constituted on an opaque sheet, the photographic document used to constitute the device is of the type observable by transparency, that is to say consists of an image produced on a transparent sheet.
L'invention a également pour objet un procédé de réalisation d'un tel dispositif. The invention also relates to a method for producing such a device.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non liniitatif en regard des dessins ci-annexés qui représentent schématiquement
- figure 1 : un dispositif de présentation de document,
- figure 2 : une étape de fabrication,
- figure 3 : une seconde étape de fabrication.The invention will be better understood with the aid of the description below given by way of nonlimiting example with reference to the attached drawings which schematically represent
- Figure 1: a document presentation device,
- Figure 2: a manufacturing step,
- Figure 3: a second manufacturing step.
Comme cela a été annoncé, le dispositif de présentation de l'invention comprend essentiellement un bloc 2 de matériau transparent 3 constitué autour du document 4 photographique tel une image réalisée sur une feuille 5. As has been announced, the presentation device of the invention essentially comprises a block 2 of transparent material 3 formed around the photographic document 4 such as an image produced on a sheet 5.
Selon l'invention, au lieu d'être observable par réflexion, c'est à dire au lieu d'être constitue sur une feuille 5 opaque, le document photographique 4 utilisé pour constituer le dispositif 1 est du type observable par transparence, c'est à dire consiste en une image réalisée sur une feuille 5 transparente. According to the invention, instead of being observable by reflection, that is to say instead of being constituted on an opaque sheet 5, the photographic document 4 used to constitute the device 1 is of the type observable by transparency, it ie consists of an image produced on a transparent sheet 5.
Tel que cela a été annoncé, l'effet obtenu est particulièrement surprenant car le document photographique semble avoir été constitue au coeur même du bloc de matériau. As has been announced, the effect obtained is particularly surprising since the photographic document seems to have been constituted at the very heart of the block of material.
Le document peut être observé sous différents angles d'incidence sans que la qualité de ltobservation ne soit altérée contrairement aux dispositifs connus. The document can be observed from different angles of incidence without the quality of the observation being altered, unlike known devices.
De préférence le document a été réalisé par agrandissement d'un cliché issu d'une prise de vue photographique. Preferably, the document was produced by enlarging a snapshot from a photographic shot.
De manière également préférentielle, le matériau utilisé pour constituer le bloc est un matériau dit de qualité optique, c'est à dire offrant notamment une parfaite transparence. Also preferably, the material used to form the block is a material called optical quality, that is to say offering in particular perfect transparency.
Avantageusement mais non limitativement, ce matériau consiste en de l'acrylate de méthyle ou en du métacrylate de méthyle. Advantageously but not limited to, this material consists of methyl acrylate or of methyl metacrylate.
Il se trouve que des monomères tels l'acrylate de méthyle et le méthacrylate de méthyle sont des composés utilises dans la fabrication de nombreux articles en matériau polymérisé. It turns out that monomers such as methyl acrylate and methyl methacrylate are compounds used in the manufacture of many articles of polymerized material.
L'inconvénient est que ces monomères en solution induisent en quelque sorte la dissolution du polymère de leur type. The disadvantage is that these monomers in solution somehow induce the dissolution of the polymer of their type.
L'une des difficultés résolues par le titulaire a donc été le choix d'un support photographique qui résiste notamment l'action du méthacrylate de méthyle en solution puisque l'inclusion du document photographique nécessite l'utilisation de monomère liquide dans lequel on noie le document. One of the difficulties resolved by the holder was therefore the choice of a photographic support which notably resists the action of methyl methacrylate in solution since the inclusion of the photographic document requires the use of liquid monomer in which the document.
Selon l'invention, le document est constitué sur un film photographique transparent, c'est à dire un film qui comporte des couches sensibles à la lumière et est à même de recevoir un traitement chimique de développement. According to the invention, the document is formed on a transparent photographic film, that is to say a film which has layers sensitive to light and is capable of receiving a chemical development treatment.
Précisément le film photographique est en polyester et du type de celui prévu pour être utilisé sur un appareil de rétroprojection. Specifically, the photographic film is made of polyester and of the type intended for use on an overhead projection device.
Le titulaire propose également un procédé d'inclusion de documents constitués à partir d'un tel film. The holder also proposes a method of including documents made from such a film.
Selon ce procédé, après avoir préparé une bouillie de matériau monomère tel le mêthacrylate de méthyle 3 et de flocons du même matériau polymérisé, on coule cette bouillie dans un moule 7 de forme prédéterminée et ce en assurant un remplissage dudit moule 7 jusqu'à niveau du plan d'inclusion choisi pour le document 4, c'est à dire jusqu'à créer une face 8 réceptive pour ledit document,
- on pourlaisse le matériau 3 amorcer sa polymérisation en surveillant la consistance de ce dernier,
- on choisit la consistance du matériau 3 de manière telle que l'on puisse appliquer le document 4 sur la face libre 8 du bloc figé en obtenant une adhésion dudit document sur cette face, mais sans que cela induise de déformation de la face réceptrice 8 lorsque, par pression, on chasse l'air emprisonné entre le document et ladite face,
- après avoir appliqué le document 3 sur la face 8 réceptrice, on surveille l'assemblage réalisé en vue d'intervenir en cas d'éventuelles déformations du document et notamment de la courbure des coins dudit document puis, on coule à nouveau du matériau 3 en bouillie dans le moule jusqu'à atteindre de bloc l'épaisseur souhaitée,
- lorsque l'ensemble du bloc est prépolymérisé, on traite ce dernier dans un four préssurisé,
- après traitement thermique, on démoule le bloc et ou corrige l'aspect de ses faces notamment par fraisage, ponçage et polissage.According to this process, after having prepared a slurry of monomeric material such as methyl methacrylate 3 and flakes of the same polymerized material, this slurry is poured into a mold 7 of predetermined shape and this while ensuring that said mold 7 is filled to level the inclusion plan chosen for document 4, that is to say to create a receptive face 8 for said document,
the material 3 is allowed to initiate its polymerization by monitoring the consistency of the latter,
- We choose the consistency of the material 3 so that we can apply the document 4 on the free face 8 of the frozen block by obtaining adhesion of said document on this face, but without this inducing deformation of the receiving face 8 when, by pressure, the air trapped between the document and said face is expelled,
- After having applied the document 3 to the receiving face 8, the assembly carried out is monitored in order to intervene in the event of possible deformations of the document and in particular of the curvature of the corners of said document, then material 3 is again poured as a slurry in the mold until the desired thickness is reached,
- when the entire block is prepolymerized, it is treated in a pressurized oven,
- After heat treatment, the block is removed from the mold and / or the appearance of its faces is corrected, in particular by milling, sanding and polishing.
Avantageusement l'amorçage de l'amorçagela polymérisation de la couche de matériau sur laquelle est appliqué le document est opéré à l'air. Advantageously, the initiation of the initiation of the polymerization of the layer of material to which the document is applied is operated in air.
