Description

AGRAFEUSE POUR AU MOINS PEUX SORTES D'AGRAFES STAPLER FOR AT LEAST TWO KINDS OF STAPLES
On connaît de nombreuses variantes d'agrafeuses ayant un magasin pour un stock d'agrafes, ce magasin comprenant une glissière de guidage sur laquelle des agrafes sont placées en file.Numerous variants of staplers are known having a magazine for a stock of staples, this magazine comprising a guide slide on which staples are placed in line.
La glissière à une largeur déterminée qui ne permet pas de recevoir des agrafes de plusieurs largeurs.The slide with a determined width which does not allow to receive staples of several widths.
En revanche, la hauteur de la glissière est conçue pour des agrafes relativement hautes et rien ne s'oppose à placer des agrafes de plusieurs hauteurs différentes, ce choix étant dicté par l'épaisseur des produits à assembler.On the other hand, the height of the slide is designed for relatively high staples and there is nothing to prevent staples of several different heights, this choice being dictated by the thickness of the products to be assembled.
Les agrafes sont poussées en permanence par un ressort vers une butée située une petite distance au-delà de l'extrémité avant de la glissière, cette petite distance correspondant, à un faible jeu près à l'épaisseur, à l'épaisseur d'une agrafe.The staples are constantly pushed by a spring towards a stop located a small distance beyond the front end of the slide, this small distance corresponding, to a small play close to the thickness, to the thickness of a clip.
Ainsi, la première agrafe d'une file se trouve en butée longitudinale, au-dessus d'un guide surplombant une « enclume » et au- dessous d'un poussoir mobile.Thus, the first staple of a line is in longitudinal abutment, above a guide overhanging an "anvil" and below a movable pusher.
Le guide doit lui-même avoir des dimensions correspondant à celles des agrafes afin d'éviter tout coincement.The guide itself must have dimensions corresponding to those of the staples to avoid jamming.
Ces éléments ont des dimensions impératives, garantes du fonctionnement même de l'agrafeuse et par conséquent, la seule dimension d'agrafe qui peut varier, pour une agrafeuse donnée, est sa hauteur.These elements have imperative dimensions, guaranteeing the very operation of the stapler and therefore, the only dimension of staple which can vary, for a given stapler, is its height.
Or, dans la pratique, il est fréquent de devoir agrafer des produits d'épaisseurs très différentes. Le courrier d'un bureau est très souvent constitué de lettres ayant deux ou trois pages, avec ou sans pièce jointe, alors que des documents tels que devis, contrats, mémoires, etc.. peuvent atteindre cinquante pages.However, in practice, it is common to have to staple products of very different thicknesses. Office mail is very often made up of letters two or three pages long, with or without an attachment, while documents such as quotes, contracts, briefs, etc. can reach fifty pages.
Utiliser une seule agrafeuse et changer les agrafes est une opération incommode et qui ne résoud pas tous les problèmes car, comme dit ci-dessus, seule la hauteur des agrafes peut varier, alors que l'agrafage d'un document épais exige des agrafes non seulement plus hautes mais également plus larges, voire plus épaisses pour être plus rigides et résistantes.Using a single stapler and changing the staples is an inconvenient operation and does not solve all the problems because, as said above, only the height of the staples can vary, whereas stapling a thick document requires staples not only higher but also wider, or even thicker to be more rigid and resistant.
Il faut donc disposer de plusieurs agrafeuses mais s'il faut prévoir deux ou trois agrafeuses différentes pour chaque poste de travail, on aboutit très vite à des dépenses élevées et à une certaine complication.It is therefore necessary to have several staplers but if it is necessary to provide two or three different staplers for each work station, it very quickly leads to high costs and a certain complication.
Les agrafeuses sont des outils qui ne sont pas seulement utilisés pour les activités de bureau mais également dans le commerce et l'industrie.Staplers are tools that are not only used for office activities but also in commerce and industry.
Outre les gros travaux qui nécessitent des agrafes de gros calibre mises en place au moyen de doueuses, il est de plus en plus fréquent d'utiliser des agrafes pour assembler des pièces entre elles, notamment dans l'industrie du meuble et de la décoration.In addition to large jobs which require staples of large caliber put in place by means of machines, it is more and more frequent to use staples to assemble parts between them, in particular in the industry of furniture and decoration.
Quelles que soient les applications envisagées, il existe un besoin pour une agrafeuse non pas universelle, mais polyvalente, permettant l'emploi d'au moins deux calibres d'agrafes, pouvant être sélectionnées facilement.Whatever the applications envisaged, there is a need for a stapler not universal, but versatile, allowing the use of at least two sizes of staples, which can be easily selected.
La présente invention apporte une solution à ce problème et, à cette fin, a pour objet une agrafeuse, du type comprenant :The present invention provides a solution to this problem and, for this purpose, relates to a stapler, of the type comprising:
* Un ensemble de stockage et de poussée d'agrafes placées en file, les une contre les autres, * A set of storage and pushing of staples placed in line, one against the other,
Un poussoir monté mobile perpendiculairement aux agrafes,A pusher mounted movable perpendicular to the staples,

FEUU1E DE REMPLA E * Des moyens de rapprochement et d'écartement du poussoir et de l'enclume,REPLACEMENT FIRE * Means of approximation and spacing of the pusher and the anvil,
Caractérisée en ce que l'ensemble de stockage et de poussée des agrafes comprend au moins deux glissières superposées, de largeurs différentes, pour des agrafes de largeurs coordonnées à celles des glissières, poussoir qui est associé à un guide adapté aux dimensions dudit poussoir et qui est situé au-dessus d'une autre guide destiné à recevoir des agrafes de toutes les largeurs et ayant, à cet effet, une largeur correspondant à celles des plus grandes agrafes.Characterized in that the staple storage and pushing assembly comprises at least two superimposed slides, of different widths, for clips of widths coordinated with those of the slides, push button which is associated with a guide adapted to the dimensions of said push button and which is located above another guide intended to receive staples of all widths and having, for this purpose, a width corresponding to those of the largest staples.

- La figure 9 est une vue schématique d'ensemble d'une agrafeuse conforme à l'invention.- Figure 9 is a schematic overview of a stapler according to the invention.
En se reportant au dessin, on voit qu'une agrafeuse conforme à l'invention est réalisée ici sous la forme, bien connue en soi, d'une pince possédant deux mâchoires 1 et 2 articulées entre elles par un pivot 3.Referring to the drawing, it can be seen that a stapler in accordance with the invention is produced here in the form, well known per se, of a clamp having two jaws 1 and 2 articulated together by a pivot 3.
La Mâchoire 1 est solidaire d'un levier de commande 4 disposé en antagonisme d'un second levier de commande 5, qui présente une lumière en arc de cercle 6 dans laquelle s'étend le pivot 3 et dont l'extrémité 7 opposée au second levier 5, porte un pion 8.The Jaw 1 is integral with a control lever 4 arranged in opposition to a second control lever 5, which has a light in an arc of a circle 6 in which the pivot 3 extends and whose end 7 opposite to the second lever 5, carries a pawn 8.
En début de course de serrage des leviers 4 et 5, le pivotement se fait selon l'axe du pivot 3 alors que celui-ci est situé à la partie supérieure de la lumière 6.At the start of the tightening stroke of the levers 4 and 5, the pivoting takes place along the axis of the pivot 3 while the latter is located at the top of the slot 6.
Cela a pour conséquence que la mâchoire 1 se rapproche de la mâchoire 2.This has the consequence that the jaw 1 approaches the jaw 2.
En continuant l'effort de serrage des leviers 4 et 5, le pivot 3 se déplace dans la lumière 6 puisque les mâchoires 1 et 2 sont en butée l'une contre l'autre et ne peuvent donc plus se rapprocher d'avantage.Continuing the effort of tightening the levers 4 and 5, the pivot 3 moves in the lumen 6 since the jaws 1 and 2 are in abutment against one another and therefore can no longer come closer.
Le pivot 3 coulisse alors dans la lumière 6 jusqu'à l'extrémité inférieure de ladite lumière 6 et permet au levier 5 de continuer de pivoter vers le levier 4, de sorte que l'extrémité 7 abaisse le pion 8. PCIYFR95/01754The pivot 3 then slides in the lumen 6 to the lower end of said lumen 6 and allows the lever 5 to continue to pivot towards the lever 4, so that the end 7 lowers the pin 8. PCIYFR95 / 01754
Ce pion 8 est engagé dans une fente d'un poussoir 10 monté coulissant, de sorte que le mouvement relatif entre les leviers 4 et 5 a pour conséquence, en fin de course de serrage, que le poussoir 10 est entraîné vers la mâchoire 2 qui porte une enclume 1 1.This pin 8 is engaged in a slot of a pusher 10 mounted to slide, so that the relative movement between the levers 4 and 5 has the consequence, at the end of the tightening stroke, that the pusher 10 is driven towards the jaw 2 which carries an anvil 1 1.
Conformément à l'invention, l'agrafeuse peut être utilisée pour deux calibres d'agrafes, ce calibre étant considéré non pas vis-à-vis de la longueur des branches, c'est à dire à la hauteur H des agrafes, mais vis-à-vis de largeur L et de l'épaisseur E des agrafes (figures 5 et 6).According to the invention, the stapler can be used for two sizes of staples, this size being considered not with respect to the length of the branches, that is to say at the height H of the staples, but screws -with respect to width L and thickness E of the staples (Figures 5 and 6).
A cet effet, l'agrafeuse possède un ensemble 20 de stockage et de poussée des agrafes qui comprend deux glissières 21 et 22 superposées, chacune d'elles étant adaptée à un calibre d'agrafes et portant une série d'agrafes respectivement A1 et A2.To this end, the stapler has a set 20 for storing and pushing the staples which comprises two superimposed slides 21 and 22, each of them being adapted to a caliber of staples and carrying a series of staples A1 and A2 respectively. .
Chacune des deux glissières 21 et 22 est mobile par rapport à l'autre et peut être sélectionnée pour être placée soit en position active alors que l'autre est en position neutre, soit en position neutre alors que l'autre est en position active.Each of the two slides 21 and 22 is movable relative to the other and can be selected to be placed either in the active position while the other is in the neutral position, or in the neutral position while the other is in the active position.
En position active, la glissière sélectionnée est en position avancée, la première des agrafes A1 ou A2 qu'elle porte étant en butée à l'aplomb du poussoir 10, l'autre glissière étant alors en position reculée.In the active position, the selected slide is in the advanced position, the first of the staples A1 or A2 that it carries being in abutment in line with the pusher 10, the other slide then being in the retracted position.
Le poussoir 10 et l'enclume 11 sont uniques car ils sont adaptés aux deux calibres d'agrafes A1 et A2.The pusher 10 and the anvil 11 are unique because they are suitable for the two sizes of staples A1 and A2.
En revanche, la première agrafe d'une série, quel que soit son calibre, et donc quelle que soit la glissière sélectionnée, est située au-dessus d'un guide d'agrafes 23 dont la section est adaptée aux dimensions de l'agrafe A2 de plus fort calibre.On the other hand, the first clip in a series, whatever its caliber, and therefore whatever the slide selected, is located above a clip guide 23 whose section is adapted to the dimensions of the clip A2 of higher caliber.
Le poussoir 10 est associé à un guide 24 formé par deux éléments distincts, à savoir une plaque et un galet dont l'écartement est égal, à un faible jeu près, à l'épaisseur du poussoir 10.The pusher 10 is associated with a guide 24 formed by two distinct elements, namely a plate and a roller whose spacing is equal, to within a small clearance, to the thickness of the pusher 10.
FOUIE DE REMPLACEMENT (REGLE 2b; L'agrafeuse est donc utilisable pour deux sortes d'agrafes A1 et A2 mais possède un poussoir 10 unique et une enclume 11 unique.REPLACEMENT HALF (RULE 2b; The stapler can therefore be used for two kinds of staples A1 and A2 but has a single pusher 10 and a single anvil 11.
Pour sélectionner les agrafes que l'on veut utiliser, on prévoit ici un volant 30 monté pivotant selon un axe perpendiculaire à celui des glissières 21 et 22 et solidaire de deux pions excentrés 31 et 32.To select the staples to be used, a flywheel 30 is provided here which is pivotally pivoted along an axis perpendicular to that of the slides 21 and 22 and secured to two eccentric pins 31 and 32.
Le pion 31 est engagé dans une lumière oblongue d'une coulisse 33 solidaire de la glissière 21 et le pion 32 est engagé dans une lumière oblongue d'une coulisse 34 solidaire de la glissière 22.The pin 31 is engaged in an oblong slot in a slide 33 secured to the slide 21 and the pin 32 is engaged in an oblong slot in a slide 34 secured to the slide 22.
En faisant pivoter le volant 30 dans un sens, on fait simultanément avancer la coulisse 33 et reculer la coulisse 34, et en faisant pivoter le volant 30 dans le sens opposé, on fait simultanément reculer la coulisse 33 et avancer la coulisse 34.By pivoting the steering wheel 30 in one direction, the slide 33 is simultaneously advanced and the slide 34 moved back, and by rotating the flywheel 30 in the opposite direction, the slide 33 is simultaneously moved back and the slide 34 advanced.
Dans le premier cas on met la glissière 21 en position active et la glissière 22 en position de repos, ce qui correspond à la mise en place des agrafes A1 (figures 1 et 2), alors que dans le second cas, on met la glissière 21 en position de repos et la glissière 22 en position active, ce qui correspond à la mise en place des agrafes A2 (figures 3 et 4).In the first case, the slide 21 is put in the active position and the slide 22 in the rest position, which corresponds to the positioning of the staples A1 (FIGS. 1 and 2), while in the second case, the slide is put 21 in the rest position and the slide 22 in the active position, which corresponds to the positioning of the staples A2 (FIGS. 3 and 4).
Pour assurer l'immobilité des glissières 21 et 22 quelle que soit leur position, c'est-à-dire pour garantir la stabilité du choix des agrafes, le volant 30 possède deux billes 35 et 36 situées dans deux puits 37 contenant des ressorts de poussée 38, la partie inférieure de la mâchoire 1 présentant deux logements dans lesquels les billes 35 et 36 sont poussées par les ressorts 38.To ensure the immobility of the slides 21 and 22 whatever their position, that is to say to guarantee the stability of the choice of staples, the flywheel 30 has two balls 35 and 36 located in two wells 37 containing springs of thrust 38, the lower part of the jaw 1 having two housings in which the balls 35 and 36 are pushed by the springs 38.
Dans une position donnée des glissières 21 et 22, la bille 35 est située vers l'avant de l'agrafeuse et la bille 36 vers l'arrière (figures 1 et 2), alors que dans l'autre position des glissières 21 et 22, la bille 35 est située vers l'arrière de l'agrafeuse et la bille 36 vers l'avant (figures 3 et 4). Il est facile de faire pivoter volontairement le volant 30 car il suffit de vaincre l'effort de poussée des ressorts 38.In a given position of the slides 21 and 22, the ball 35 is located towards the front of the stapler and the ball 36 towards the rear (Figures 1 and 2), while in the other position of the slides 21 and 22 , the ball 35 is located towards the rear of the stapler and the ball 36 towards the front (Figures 3 and 4). It is easy to pivot the steering wheel 30 voluntarily because it suffices to overcome the thrust force of the springs 38.
En revanche, les billes 35 et 36 ne peuvent pas sortir accidentellement des logements.On the other hand, the balls 35 and 36 cannot accidentally leave the housings.
Par exemple, en pratique, on peut utiliser avec une agrafeuse conforme à l'invention des agrafes A1 dont la largeuπsst de 9 millimètres et des agrafes A2 dont la largeur est de 12 millimètres. Leur épaisseur E peut varier de 0.3 à 0.8 millimètres, pour un poussoir 10 dont l'épaisseur est de 0.7 millimètres.For example, in practice, it is possible to use, with a stapler according to the invention, staples A1 the width of which is 9 millimeters and staples A2 the width of which is 12 millimeters. Their thickness E can vary from 0.3 to 0.8 millimeters, for a pusher 10 whose thickness is 0.7 millimeters.
La hauteur H des agrafes peut également varier mais cela n'est pas nouveau en soi puisque cela se pratique déjà couramment : on donne à la glissière recevant les agrafes une hauteur égale à la hauteur maximum possible pour les agrafes, toutes les hauteurs inférieures étant automatiquement acceptables.The height H of the staples can also vary but this is not new in itself since this is already common practice: the slide receiving the staples is given a height equal to the maximum possible height for the staples, all the lower heights being automatically acceptable.
A noter que chaque glissière 21-22 est associée à un mécanisme de type connu comprenant un poussoir d'agrafes sollicité en permanence par un ressort respectivement 25 et 26, chaque série d'agrafes étant ainsi complètement autonome.Note that each slide 21-22 is associated with a mechanism of known type comprising a staple plunger permanently biased by a spring 25 and 26 respectively, each series of staples thus being completely autonomous.
Bien entendu, les moyens que l'on vient de décrire à titre d'exemple peuvent être remplacés par d'autres équivalents. En particulier le mécanisme de sélection des agrafes peut être réalisé autrement.Of course, the means which have just been described by way of example can be replaced by other equivalents. In particular, the staple selection mechanism can be carried out differently.
De même, le nombre de sortes d'agrafes différentes peut être supérieur à deux, dés lors que l'on reste dans les limites acceptables pour le guidage des agrafes vers l'enclume 1 1. Likewise, the number of different kinds of staples can be greater than two, as long as one remains within the acceptable limits for guiding the staples towards the anvil 11.
