Abstract

The invention relates to an improvement in binders for perforated sheets with two flexible plastic binding parts (3), one end of which has a projecting head which passes through the perforations of the sheets, a slide in the form of a flattened "C" (1) having at its ends openings (4), one of which is traversed by the end of one of the binding parts (3), the back of the channel being applied onto the last bound sheet and, finally, on the face opposite the back, two sliders (2) having two projections (2a) engaged under the opposite edges of the slide and joined by a central portion (2b) in the form of a bridge under which are engaged the ends of the binding parts with a view to their locking. The device is characterised in that each of the ends of the slide carries, on the face opposite the back, a thin metal plate (8) engaged under its edges, the said plate having a sharp-edged opening (7a) with a diameter very close to that of the binding parts and which is traversed by the corresponding binding part. This device makes it possible to prevent relative sliding of the binding parts and of the slide. <IMAGE>

Description

L'invention est relative aux dispositifs de reliure pour feuillets perforés notamment pour feuillets venant d'ordinateur.The invention relates to binding devices for perforated sheets, in particular for sheets coming from a computer.

En vue de relier de tels feuillets perforés, éventuellement encore pliés "en paravent", il est connu d' utiliser des dispositifs de reliure comportant, d'une part, deux broches souples en matière plastique de grande résistance à la traction dont une extrémité est effilée, tandis que l'autre présente une tête débordante, qui traverse les perforations homologues de chaque feuillet respectivement au voisinage de chaque extrémité de l'un de ses bords avec interposition d'une couverture convenable, d'autre part, une réglette de retenue en matière plastique en forme de gouttière en "C" aplatie présentant à chacune de ses extrémités une pluralité d'ajours dont l'un est traversé par l'extrémité effilée de l'une des broches, le dos de la gouttière étant appliqué sur le dernier feuillet relié, et enfin, sur la face opposée au dos, deux coulisseaux comportant latéralement chacun deux talons engagés de façon coulissante sous les bords en regard de la réglette qui forme ainsi une glissière pour lesdits coulisseaux dont les talons sont réunis par une partie centrale en forme de pont sous laquelle sont engagées,sans jeu, respectivement les extrémités libres des broches en vue de leur blocage après serrage de la liasse de feuillets entre la tête des broches et la réglette.In order to connect such perforated sheets, possibly still folded "in folding screen", it is known to use binding devices comprising, on the one hand, two flexible pins of high tensile plastic material, one end of which is tapered, while the other has an overhanging head, which passes through the homologous perforations of each sheet respectively in the vicinity of each end of one of its edges with the interposition of a suitable cover, on the other hand, a retaining strip plastic material in the form of a flattened "C" gutter having at each of its ends a plurality of openings, one of which is crossed by the tapered end of one of the pins, the back of the gutter being applied to the last connected sheet, and finally, on the side opposite the back, two slides each having two laterally two heels slidably engaged under the edges opposite the strip which thus forms a slide for said slides whose heels are joined by a central part in the form of a bridge under which are engaged, without play, respectively the free ends of the pins for blocking after tightening the bundle of sheets between the head of the pins and the strip.

Ces dispositifs ne donnent pas totalement satisfaction, notamment lorsqu'un grand nombre de feuillets sont ainsi réunis; en effet, malgré la constitution très légère du dispositif de reliure, le poids de l'ensemble atteint fré- quemment plusieurs kilogrammes et il en résulte, au cours des manipulations, un desserrage de la liasse par glissement des broches en matière plastique dans les ajours de la réglette, également constituée, pour des raisons de prix de revient et de facilité de fabrication, en une matière plastique, généralement par extrusion. Cet inconvénient vient, en fait, de ce que les matières plastiques présentent les unes par rapport aux autres un faible coefficient de frottement; il peut déterminer, dans les cas extrêmes, la libération des feuillets, ce qui est évidemment à éviter; dans les cas moins graves, le desserrage fréquent de la liasse impose des manoeuvres fastidieuses de resserrage au cours desquelles les broches doivent être dégagées de leurs coulisseaux, la liasse resserrée entre les têtes de broches et la réglette, puis les coulisseaux à nouveau glissés dans.les parties extrêmes des broches de manière à les immobiliser en coulissement. Il y a d'ailleurs lieu de remarquer que cette tendance au desserrage de l'assemblage par glissement relatif de la réglette et des broches est d'autant plus grand que, selon une disposition connue, le dispositif de reliure est généralement, en position de non utilisation, maintenu suspendu par une réglette de suspension insérée dans la liasse sensiblement au milieu de son épaisseur et dont des ajours convenables sont traversés par les broches, les bords libres des feuillets opposés à ceux-ci pendant ainsi verticalement vers le bas. Il est clair, ainsi, que la libération des feuillets nécessiterait une opération longue et coûteuse de reclassement en vue d'une nouvelle confection de la liasse.These devices are not entirely satisfactory, in particular when a large number of sheets are thus combined; in fact, despite the very light constitution of the binding device, the weight of the assembly frequently reaches several kilograms and this results, during handling, in loosening the bundle by sliding the plastic pins in the openings of the strip, also made, for reasons of cost price and ease of manufacture, of a plastic material, generally by extrusion. This drawback comes, in fact, from the fact that plastics have a low coefficient of friction with respect to each other; it can determine, in extreme cases, the release of the sheets, which is obviously to be avoided; in less severe cases, frequent loosening of the bundle requires tedious tightening maneuvers during which the pins must be released from their slides, the bundle tightened between the heads of the pins and the slide, then the slides again slid in. the end parts of the pins so as to immobilize them by sliding. It should also be noted that this tendency to loosen the assembly by relative sliding of the strip and the pins is all the greater when, according to a known arrangement, the binding device is generally in the position of not in use, kept suspended by a suspension strip inserted in the bundle substantially in the middle of its thickness and of which suitable openings are crossed by the pins, the free edges of the sheets opposite to the latter thus hanging vertically downwards. It is thus clear that the release of the sheets would require a long and costly reclassification operation with a view to re-making the bundle.

L'invention a pour objet d'éviter ces inconvénients tout en conservant les avantages de prix de revient et de simplicité de fabrication exposés ci-dessus.The object of the invention is to avoid these drawbacks while retaining the advantages of cost price and simplicity of manufacture described above.

A cet effet, elle concerne une réglette telle que précédemment définie, remarquable en ce que, en vue d'éviter le glissement relatif de ladite réglette par rapport aux bords, chacune de ses extrémités porte sur la face opposée au dos, une plaquette métallique mince engagée de façon coulissante sous les bords formant glissière, ladite plaquette présentant un ajour à bords vifs de diamètre très voisin du diamètre de section des broches et qui est, après mise en coïncidence avec l'ajour convenable de la réglette traversé par la broche correspondante.To this end, it relates to a strip as defined above, remarkable in that, with a view to avoiding the relative sliding of said strip relative to the edges, each of its ends carries on the face opposite the back, a thin metal plate slidably engaged under the edges forming a slide, said plate having an openwork with sharp edges of diameter very close to the diameter of section of the pins and which is, after being placed in coincidence with the suitable openwork of the strip crossed by the corresponding pin.

D'autres caractéristiques du dispositif selon l'invention apparaitront à la lecture de la description qui va suivre faite en référence aux dessins annexés dans lesquels:

  • la figure 1 est une vue en plan avec arrachement partiel et rapprochement, de l'extrémité de droite d'une réglette avec plaquette métallique selon l'invention,
  • la figure 2 est une coupe avec arrachement, par II-II de la figure 1 sur laquelle quelques feuillets seulement ont été représentés,
  • la figure 3 est une coupe par III-III de la figure 1,
  • la figure 4 est une perspective de la plaquette métallique,
  • et la figure 5 une vue schématique dans le même sens que la figure 2 d'un dispositif de reliure selon l'invention, muni de deux couvertures et chargé d'un grand nombre de feuillets.
Other characteristics of the device according to the invention will appear on reading the description which follows, made with reference to the appended drawings in which:
  • FIG. 1 is a plan view with partial cutaway and approximation, of the right end of a strip with metal plate according to the invention,
  • FIG. 2 is a cutaway view, by II-II of FIG. 1 on which only a few sheets have been shown,
  • FIG. 3 is a section through III-III of FIG. 1,
  • FIG. 4 is a perspective of the metal plate,
  • and Figure 5 a schematic view in the same direction as Figure 2 of a binding device according to the invention, provided with two covers and loaded with a large number of sheets.

Sur les figures,l désigne la réglette de suspension qui présente en coupe une forme générale de "C" aplati dont la branche médiane la porte à chaque extrémité une série d'ajours oblongs 4 destinés à être traversés par une broche souple en matière plastique 3 qui comporte, d'une part, une large tête débordante 3a et, à l'extrémité opposée, une partie extrême constituée de façon effilée 3b de manière à faciliter sa pénétration à travers les ajours tels que 5 des feuillets à relier 6.In the figures, l denotes the suspension strip which has in section a general shape of a flattened "C", the middle branch of which carries it at each end with a series of oblong openings 4 intended to be crossed by a flexible plastic pin 3 which comprises, on the one hand, a large projecting head 3a and, at the opposite end, an end part which is tapered 3b so as to facilitate its penetration through the openings such as 5 of the sheets to be bound 6.

La branche médiane la de la réglette présente une face Ib qui en constitue le dos et une face le opposée à ce dernier et qui est orientée vers l'intérieur du "C". De part et d'autre de ladite branche médiane, la réglette présente deux ailes longitudinales ld redressée d'équerre, prolongées par les bords en regard le dont les parties extrêmes 1f sont, dans l'exemple, rabattues en direction de la face lc de manière à constituer avec elle une glissière pour les talons latéraux 2a du coulisseau 2 sensiblement en forme d"Oméga" dont la partie centrale 2b reliée aux talons 2a par les bords à angle droit 2d, constituent un pont qui peut être glissé par dessus l'extrémité libre de la partie médiane de la broche 3. Il est à remarquer en outre que les bords 2d, qui se présentent transversalement à la face longitudinale le de la réglette constituent, en coopération avec les parties extrêmes If, en regard, de cette dernière, des éléments de guidage longitudinal pour les coulisseaux qui, après mise en place des broches à travers les ajours 5 des feuillets et de la couverture sont glissés par dessus lesdites broches (figure 3) sur lesquelles ils exercent une compression destinée à coincer ces dernières dans les ajours 4, de manière à éviter leur glissement à travers ces derniers, glissement qui, évidemment, déterminerait le desserrage de la liasse des feuillets 6.The middle branch 1a of the strip has a face Ib which constitutes its back and a face opposite it and which is oriented towards the inside of the "C". On either side of said middle branch, the strip has two longitudinal wings ld straightened square, extended by the opposite edges the end portions 1f of which are, in the example, folded down towards the face lc of so as to constitute with it a slide for the lateral heels 2a of the slider 2 substantially in the shape of an "Omega", the central part 2b connected to the heels 2a by the edges at right angles 2d, constitute a bridge which can be slid over the free end of the middle part of the spindle 3. It should also be noted that the edges 2d, which are presented transversely to the longitudinal face the of the strip constitute, in cooperation with the end parts If, opposite, of the latter , longitudinal guide elements for the slides which, after the positioning of the pins through the openings 5 of the sheets and of the cover are slid over the said pins (FIG. 3) on which they exert a compression intended to wedge the latter in the openings 4, so as to avoid their sliding through the latter, sliding which, obviously, would determine the loosening of the bundle of sheets 6.

Il est clair cependant, qu'en raison du faible coefficient de frottement que les matières plastiques présentent les unes par rapport aux autres (notamment lorsque, selon la pratique habituelleen la matière, et en vue de réduire le prix de revient, la réglette est constituée en polystyrène extrudé, tandis que le clou est moulé en polyéthylène), l'assemblage ainsi réalisé aura tendance à glisser au cours des manoeuvres de la reliure ou sous le poids de cette dernière lorsque, de façon connue, elle est maintenue suspendu à l'aide d'une réglette de suspension insérée au milieu de la liasse et traversée par les broches.It is clear, however, that due to the low coefficient of friction that plastics have relative to each other (especially when, according to the usual practice in the material, and in order to reduce the cost price, the strip is made in extruded polystyrene, while the nail is molded in polyethylene), the assembly thus produced will tend to slip during the maneuvers of the binding or under the weight of the latter when, in known manner, it is kept suspended from the using a suspension strip inserted in the middle of the bundle and crossed by the pins.

Pour remédier à cet inconvénient, il est proposé, selon l'invention, de disposer sur la face intérieure le de la réglette une plaquette métallique 8, de préférence réalisée en acier et qui présente un ajour 7 de diamètre très voisin du diamètre de la section droite des broches 3, l' ajour étant réalisé par exemple par poinçonnage, de manière telle que, au moins son bord 7a de même orientation que la face lc , se présente sous la forme d'une arête vive; notamment, lorsque l'ajour 7 est réalisé par une opération de poinçonnage, l'on choisira, pour constituer le bord 7a, le côté de la plaquette qui porte les bavures de débouchage, inévitables au cours d'une telle opération.To overcome this drawback, it is proposed, according to the invention, to have on the inner face of the strip a metal plate 8, preferably made of steel and which has an aperture 7 of diameter very close to the diameter of the section right of the pins 3, the aperture being produced for example by punching, so that at least its edge 7a of the same orientation as the face lc, is in the form of a sharp edge; in particular, when the aperture 7 is produced by a punching operation, one will choose, to constitute the edge 7a, the side of the plate which carries the unblocking burrs, inevitable during such an operation.

Il est clair que dans ces conditions lorsque le coulisseau 2 sera, après serrage de la liasse, glissé par dessus la broche 3 en direction de l'extrémité correspondante de la réglette, c'est-à-dire vers la droite dans les figures 1 et 3 et lorsque, parvenu dans la position desdites figures 1 et 3, il exercera une compression en direction de la face lc sur le coude formé en 3c par la broche, il déterminera une légère pénétration de l'arête vive 7a de l'ajour de la plaquette dans la matière constitutive de ladite broche, pénétration qui sera suffisante pour constituer un verrouillage très efficace contre le glissement longitudinal de cette dernière à travers les ajours.It is clear that under these conditions when the slider 2 is, after tightening the bundle, slid over the pin 3 towards the corresponding end of the strip, that is to say to the right in Figures 1 and 3 and when, having reached the position of said FIGS. 1 and 3, it will exert a compression in the direction of the face lc on the elbow formed in 3c by the spindle, it will determine a slight penetration of the sharp edge 7a of the aperture of the plate in the material of said spindle, penetration which will be sufficient to constitute a very effective locking against the longitudinal sliding of the latter through the openings.

Il est ainsi remédié de façon efficace et avec mise en oeuvre de moyens très simples et très peu onéreux a 1' inconvénient signalé dans l'introduction.It is thus remedied effectively and with the use of very simple and very inexpensive means has the drawback mentioned in the introduction.

Dans l'exemple, la plaquette présente une largeur telle qu'elle peut coulisser sous les bords longitudinaux 1f de la réglette de manière à être retenue par ceux-ci lorsque le coulisseau n'est pas à son aplomb. Elle peut ainsi être amenée en regard de celui des ajours 4 qui est choisi compte tenu de l'espacement des perforations des feuillets à relier.In the example, the plate has a width such that it can slide under the longitudinal edges 1f of the strip so as to be retained by them when the slide is not plumb. It can thus be brought opposite that of the openings 4 which is chosen taking into account the spacing of the perforations of the sheets to be connected.

Par ailleurs, il a été constitué sur les bords latéraux 8a de la plaquette, au cours de l'opération de poinçonnage, deux bossages 8b (voir notamment figure 4) qui sont destinés à coopérer avec des éléments de butée 9 ménagés sur les bords 1f au voisinage des extrémités de la réglette par simple déformation à chaud desdits bords. Cette disposition permet d'assurer le verrouillage des plaquettes 8 à l'intérieur de la réglette tandis que la forme des bossages en moitié de cornet, d'ouverture orientée vers l'extérieur, permet la mise en place des plaquettes par simple déformation élastique de celles-ci à ce niveau.Furthermore, it was formed on the lateral edges 8a of the wafer, during the punching operation, two bosses 8b (see in particular Figure 4) which are intended to cooperate with abutment elements 9 formed on the edges 1f in the vicinity of the ends of the strip by simple hot deformation of said edges. This arrangement ensures the locking of the plates 8 inside the strip while the shape of the bosses in half of horn, opening facing outwards, allows the positioning of the plates by simple elastic deformation of these at this level.

Alors que, pour la simplicité de l'exposé, les figures 2 et 3 ne représentent que quelques feuillets maintenus entre la tête 3a de la broche et la tête 1b de la réglette, la figure 5 montre, bien que de façon schématique, un dispositif complet de reliure selon l'invention dans lequel on reconnait la réglette 1, son coulisseau 2, les broches 3 qui traversent par leurs perforations convenables la liasse des feuillets 6.Whereas, for the simplicity of the description, FIGS. 2 and 3 represent only a few sheets held between the head 3a of the spindle and the head 1b of the strip, FIG. 5 shows, although schematically, a device complete binding according to the invention in which we recognize the strip 1, its slide 2, the pins 3 which pass through their suitable perforations the bundle of sheets 6.

On remarquera que, dans cet exemple, deux couvertures 10, 11 ont été interposées respectivement entre la réglette 1 et le feuillet de dessus de la liasse et entre la tête 3a des broches et le feuillet de dessous de ladite liasse de manière à constituer, selon l'usage, une reliure apte à protéger efficacement les feuillets qu'elle contient.It will be noted that, in this example, two covers 10, 11 have been interposed respectively between the strip 1 and the top sheet of the bundle and between the head 3a of the pins and the bottom sheet of said bundle so as to constitute, according to use, a binding capable of effectively protecting the sheets it contains.

Bien entendu, le mode de réalisation décrit ci-dessus est donné à titre de simple exemple et il pourrait y être apporté de nombreuses variantes sans pour celà sortir du domaine de protection de l'invention.Of course, the embodiment described above is given by way of simple example and it could be made many variants without thereby departing from the scope of protection of the invention.
