Abstract

The document file with extensible back comprises two flat portions, the back being fixed to the one and sliding in the other, together with a holding strap. The buckle (6) at one end of the strap (4) slides on one of the flat portions (2), while the strap is fixed at one or more points (17) to the other one (1), typically by a rivet. The design is easy to assemble and tighten without the risk of spoiling the file or the documents contained, while avoiding the risk of the strap becoming detached. The strap passes through two pairs of openings (13,14,15,16) formed in the two panels and is fixed by the rivet between two of the openings (15,16).

Description

L'invention a pour objet un dossier à dos extensible. The subject of the invention is a file with an expandable back.

Pour loger des documents quelconques, il est bien connu d'utiliser des dossiers ou chemises à dos extensible. To house any documents, it is well known to use files or folders with extendable backs.

Ils sont constitués par deux éléments plats et rigides, généralement à base de carton-, entoiles ou non, et reliés par un dos souple qui, solidaire de l'un des éléments et le prolongeant, est monté coulissant à l'intérieur de l'autre. C'est ce troisieme élément, c'est-à-dire le dos, qui confère au dossier son son caractère extensible et permet ainsi d'y recevoir une plus ou moins grande épaisseur de documents. Des moyens doivent bien entendu etre prévus pour que ces documents, quelle que soit leur épaisseur, soient maintenus serrés dans le dossier. Ces moyens consistent le plus souvent en une simple sangle en textile qui dans la plupart des cas porte, à l'une de ses extrémité une boucle métallique avec laquelle coopère le brin libre de la lanière.They consist of two flat and rigid elements, generally cardboard-based, star or not, and connected by a flexible back which, integral with one of the elements and extending it, is slidably mounted inside the other. It is this third element, that is to say the back, which gives the file its stretchable nature and thus allows it to receive a greater or lesser thickness of documents. Means must of course be provided so that these documents, whatever their thickness, are kept tight in the file. These means most often consist of a simple textile strap which in most cases carries, at one of its ends a metal loop with which the free strand of the strap cooperates.

Dans certains dossiers cette sangle est entièrement libre par rapport au dossier proprement dit ; elle constitue une simple ceinture qui permet un serrage efficace, mais elle risque d'être perdue et surtout rend ce serrage assez difficile en raison précisément de l'absence de toute liaison entre la sangle et le dossier. In some files this strap is completely free compared to the file itself; it constitutes a simple belt which allows effective tightening, but it risks being lost and above all makes this tightening quite difficult precisely because of the absence of any connection between the strap and the backrest.

Pour remédier à ces inconvénients, on a pensé à rendre la sangle solidaire du dossier ; et c'est ainsi que sont connus des dossiers dans lesquels la sangle est localement fixée au dossier. To remedy these drawbacks, it has been thought to make the strap integral with the backrest; and this is how files are known in which the strap is locally attached to the file.

Les dossiers de ce type sont commodes, mais il s'avère qu'il est difficile de serrer efficacement le dossier autour des documents contenus et que l'effort produit pour tenter d'obtenir un serrage efficace conduit assez souvent à l'arrachage de la boucle métallique et à la déterio- ration de l'élément du dossier sur lequel elle est fixée. Files of this type are convenient, but it turns out that it is difficult to effectively clamp the file around the documents contained and that the effort produced to try to obtain an effective clamping quite often leads to the uprooting of the metal buckle and to the deterio- ration of the backrest element on which it is fixed.

Ces inconvénients proviennent du principe même du montage de la sangle sur le dossier.These drawbacks arise from the very principle of mounting the strap on the backrest.

Ce principe est illustré schématiquement par la figure 1 du dossier annexé dans laquelle 1 et 2 désignent respect tivement les deux éléments plats du dossier, 3 son dos extensible solidaire de l'élément 1 et monté coulissant dans celui 2 et 4 désigne la sangle de serrage. Cette sangle se termine par une boucle d'accrochage 6 qui apparait à l'extérieur de l'élément plat 1 et elle est fixée par collage à I'intérieur de cet élément sur toute sa zone située entre les deux fenêtres 7 et 8 lui permettant de passer à travers ledit élément. Deux autres fenêtres 9 et 10 sont prévues dans l'autre élément 2, mais la sangle peut y coulisser librement pour permettre précisément le serrage.Il faut cependant constater que, lorsque l'extrémité libre de la sangle 4 est passée au travers de la boucle 6 et qu'une traction y est exercée pour réaliser le serrage, cette traction entraine sur la boucle une contre-réaction d'intensité double qui conduit fréquemment à l'arrachage de la boucle. This principle is illustrated diagrammatically by FIG. 1 of the appended file in which 1 and 2 respectively designate the two flat elements of the file, 3 its extendable back secured to the element 1 and mounted sliding in that 2 and 4 designates the tightening strap . This strap ends with a hooking loop 6 which appears outside the flat element 1 and is fixed by gluing inside this element over its entire area located between the two windows 7 and 8 allowing it to pass through said element. Two other windows 9 and 10 are provided in the other element 2, but the strap can slide there freely to allow precise tightening. It should however be noted that, when the free end of the strap 4 has passed through the buckle 6 and that a traction is exerted therein to effect the tightening, this traction causes on the loop a double-intensity feedback which frequently leads to the tearing of the loop.

L'invention écarte ces inconvénients : difficulté de serrage efficace et détérioration du dossier, en proposant un dossier à dos extensible dans lequel la sangle de serrage est amarrée non pas à ltéléxent plat servant de support a la boucle, mais en au moins un point ou une zone de l'autre élément plat. La boucle est ainsi mobile sur le dossier et l,effoart aui lui est imposé se traduit par une force qui est égale/ la force de traction sur le brin libre de la lanière ; et au niveau de la liaison entre le dossier et la lanière cette force ne se répercute pas sur le dossier lui-même.  The invention overcomes these drawbacks: difficulty in effective clamping and deterioration of the backrest, by proposing an extendable backrest in which the tightening strap is not moored to the flat telexent serving as support for the buckle, but at at least one point or an area of the other flat element. The buckle is thus mobile on the backrest and the effect imposed on it results in a force which is equal / the pulling force on the free end of the strap; and at the connection between the backrest and the strap, this force does not affect the backrest itself.

Cette liaison peut, dans ces conditions, entre réalisée de façon extrèmement simple, à savoir par un seul rivet, ce qui confère finalement au dossier les avantages suivants:
- une grande facilité de montage,
- une possibilité de serrage efficace sans risque de détérioration,
- et une bonne solidarisation de la sangle
L'invention sera bien comprise d'ailleurs a l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif une forme d'exécution de ce dossier à dos extensible, et dans lequel
Figures 2 et 3 en sont des vues en perspective et,
Figure 4 en est à plus grande échelle, une vue en coupe suivant 4-4 de figure 2.
This connection can, under these conditions, be carried out in an extremely simple manner, namely by a single rivet, which ultimately gives the file the following advantages:
- great ease of assembly,
- an effective clamping possibility without risk of deterioration,
- and good attachment of the strap
The invention will moreover be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this file with an expandable back, and in which
Figures 2 and 3 are perspective views and,
Figure 4 is on a larger scale, a sectional view along 4-4 of Figure 2.

Comme cela est connu en soi, et comme cela est illustré en référence à la figure i qui illustre un dossier connu, un dossier conforme à l'invention, tel que représenté aux figures 2 à 4 est constitué par deux éléments plats et rigides i et 2, de forme générale rectangulaire, réalisé par exemple en carton entoilé, et par un dos relativement souple 2 qui est solidaire de l'élément i et est monté de façon télescopique à l'intérieur de l'élément 2 et qui se présente sous forme d'une pochette ouverte en direction du dos. La sangle de serrage permettant de fermer le dossier et de le maintenir serré autour des documents 5 qui y sont contenus, est désignée par 4.Cette sangle 4 se termine par une boucle métallique 6 avec laquelle coopère avantageusement un organe d'accrochage 12 monté coulissant sur le brin libre de la sangle 4. As is known per se, and as illustrated with reference to FIG. I which illustrates a known file, a file in accordance with the invention, as shown in FIGS. 2 to 4, consists of two flat and rigid elements i and 2, of generally rectangular shape, made for example of covered cardboard, and by a relatively flexible back 2 which is integral with the element i and is mounted telescopically inside the element 2 and which is in the form an open pocket towards the back. The tightening strap for closing the file and keeping it tight around the documents 5 contained therein, is designated by 4. This strap 4 ends with a metal loop 6 with which advantageously cooperates a hooking member 12 mounted sliding on the free end of the strap 4.

Selon l'invention, l'élément plat i du dossier présente deux fenêtres li et li au travers desquelles coulisse librement le brin de la sangle 4 se terminant par-la boucle d'accrochage 6, et l'élément plat 2 présente lui-même deux fenêtres li et 16 permettant le passage de l'autre brin de la sangle, mais il est important de noter que dans sa portion comprise entre ses deux fenêtres 25 et i6 ce brin de la sangle est fixé sur l'élément plat 1 du dossier par un rivet 17.  According to the invention, the flat element i of the backrest has two windows li and li through which the strand of the strap 4 freely slides ending in the hooking loop 6, and the flat element 2 itself two windows li and 16 allowing the passage of the other strand of the strap, but it is important to note that in its portion between its two windows 25 and i6 this strand of the strap is fixed on the flat element 1 of the backrest by a rivet 17.

Quelle que soit l'épaisseur de documents 5 contenue dans le dossier, c'est-à-dire quelle que soit la hauteur du dos 2, le serrage du dossier au moyen de la sangle 4 s'effectue comme dans les dossiers connus, par traction sur le brin libre de la sangle après coopération de son organe d'accrochage i2 avec la boucle 6, mais cette traction se répercute intégralement sur l'élément plat 2 et sur le dos 3 en provoquant un coulissement de la boucle 6 et de la partie correspondante de la sangle 4 sans cependant qu'il en résulte une rotation de la sangle autour du dossier, étant donné que le rivet 17 réalise la liaison entre cette sangle et le dossier en un point situé sur l'autre élément plat du dossier, c'est-à-dire l'élément 1. Whatever the thickness of documents 5 contained in the file, that is to say whatever the height of the back 2, the tightening of the file by means of the strap 4 is carried out as in the known files, by traction on the free end of the strap after cooperation of its hooking member i2 with the loop 6, but this traction is fully reflected on the flat element 2 and on the back 3 causing a sliding of the loop 6 and the corresponding part of the strap 4 without however resulting in a rotation of the strap around the backrest, since the rivet 17 makes the connection between this strap and the backrest at a point located on the other flat element of the backrest, i.e. Element 1.

Grâce à cet agencement, le serrage est très efficace et est néanmoins obtenu beaucoup plus facilement qu'avec les dossiers correspondants habituels. En outre, le montage du dossier est lui-mème beaucoup plus facile car la liaison entre la sangle et le dossier par un simple rivet est une opération facile. Thanks to this arrangement, tightening is very effective and is nevertheless obtained much more easily than with the usual corresponding files. In addition, the mounting of the backrest itself is much easier since the connection between the strap and the backrest by a simple rivet is an easy operation.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dossier qui a été ci-des-- sus indiquée à titre d'exemple, elle en embrasse, au contraire, toutes les variantes de réalisation, quels que soient notamment le type de boucle d'accrochage et de serrage ainsi que le ou les moyens utilisés pour fixer la sangle à l'un des deux éléments plats du dossier ; et il est évident que la boucle de serrage et d'accrochage de même que la fixation de la sangle peuvent être réalisées à volonté sur l'une ou l'autre des deux éléments plats du dossier, l'essentiel étant que la boucle soit placée sur l'un des éléments et que la fixation soit faite sur l'autre élément.  As it goes without saying, the invention is not limited to the only form of execution of this file which has been above mentioned above by way of example, it embraces, on the contrary, all variants of it. realization, whatever in particular the type of hooking and tightening loop as well as the means or means used to fix the strap to one of the two flat elements of the backrest; and it is obvious that the tightening and hooking loop as well as the fixing of the strap can be carried out at will on one or the other of the two flat elements of the backrest, the main thing being that the loop is placed on one of the elements and that the fixing is made on the other element.
