Description

La présente invention concerne un dispositif destiné à pratiquer sur le bord d'un élément en feuille une perforation, avec la faculté de renforcer ledit élément autour de ladite perforation. The present invention relates to a device for making a perforation on the edge of a sheet element, with the option of reinforcing said element around said perforation.

Dans le domaine des accessoires de bureau et analogues, on utilise couramment des dispositifs connus sous le nom de perforateurs, et qui permettent de pratiquer, sur un bord d'une feuille ou de plusieurs feuilles superposées, des perforations permettant leur insertion dans un classeur comportant des tiges au même écartement que ces perforations. In the field of office accessories and the like, devices commonly known under the name of perforators are used, which make it possible to practice, on an edge of a sheet or of several superimposed sheets, perforations allowing their insertion into a binder comprising rods at the same spacing as these perforations.

En raison des manipulations nombreuses subies par ces feuilles, et aussi de leur fragilité, par exemple quand il s'agit de papier "pelure", ou de telexes ou de télécopies, il est souvent nécessaire de renforcer le bord de ces feuilles, ou le pourtour de ces perforations, au moyen de bandes, d'oeillets de papier ou de plastique, que l'on colle individuellement sur le bord desdites feuilles. Because of the numerous manipulations undergone by these sheets, and also their fragility, for example when it is "peel" paper, or telexes or faxes, it is often necessary to reinforce the edge of these sheets, or the around these perforations, by means of strips, paper or plastic eyelets, which are individually glued to the edge of said sheets.

L'invention permet de supprimer cette opération fastidieuse de renforcement, grâce à un dispositif de perforation comportant des moyens pour associer à la volonté de l'opérateur à ladite perforation, la fixation d'une plaque de matériau de renforcement à l'emplacement de la perforation. The invention makes it possible to eliminate this tedious reinforcement operation, thanks to a perforation device comprising means for associating with the will of the operator to said perforation, the fixing of a plate of reinforcement material at the location of the perforation.

A cet effet, l'invention vise une perforatrice de type général classique, à laquelle est associée un rouleau de ruban en matériau auto-adhésif comportant une feuille protectrice, des moyens étant prévus pour provoquer simultanément au moment de la perforation, l'avancée d'une longueur déterminée dudit ruban vers la zone de perforation et l'effacement de la feuille protectrice, ainsi que le sectionnement-dudit ruban, de manière que les organes de perforation exercent en même temps une pression sur une portion limitée dudit ruban autour de la perforation, la feuille protectrice étant évacuée par ailleurs. To this end, the invention relates to a perforator of the general conventional type, with which is associated a roll of tape of self-adhesive material comprising a protective sheet, means being provided for simultaneously causing the advance of the perforation. 'a determined length of said tape towards the perforation zone and the erasure of the protective sheet, as well as the cutting-off of said tape, so that the perforation members simultaneously exert pressure on a limited portion of said tape around the perforation, the protective sheet being evacuated elsewhere.

Les moyens précités consistent en un poussoir coulissant dans un couloir de la perforatrice et comportant un élément de pincement, basculant sous l'effet d'un chemin-came pratiqué dans le carter du dispositif entre une position de repos, où le ruban auto-adhésif n'intervient pas et une position d'"armement", où ledit ruban est pincé et soumis à une traction sur une longueur fixée, l'inversion de la direction de cheminement dudit ruban adhésif avant les moyens de sectionnement ayant pour conséquence l'entraînement de la feuille de protection vers l'arrière du carter et sa séparation du ruban auto-adhésif luimême, dont le déplacement se poursuit vers l'avant du carter jusqu'à l'emplacement de la perforation. The aforementioned means consist of a pusher sliding in a corridor of the hole punch and comprising a clamping element, tilting under the effect of a cam-path formed in the casing of the device between a rest position, where the self-adhesive tape does not intervene and an "arming" position, where said tape is pinched and subjected to a traction over a fixed length, the inversion of the direction of travel of said adhesive tape before the cutting means resulting in the drive of the protective sheet towards the rear of the casing and its separation from the self-adhesive tape itself, the movement of which continues towards the front of the casing until the location of the perforation.

Le système de perforation lui-même comporte des moyens ayant pour effet, soit la simple éjection du "confetti" découpé par l'organe perforation, soit la compression du fragment de ruban auto-adhésif, amené et sectionné comme il est exposé plus haut, autour de la perforation. The perforation system itself comprises means having the effect either of the simple ejection of the "confetti" cut out by the perforation member, or of the compression of the fragment of self-adhesive tape, brought and cut as described above, around the perforation.

L 'invention va être maintenant décrite plus en détail en se référant au dessin annexé, qui en illustre à titre d'exemple non limitatif un mode de réalisation. The invention will now be described in more detail with reference to the accompanying drawing, which illustrates by way of non-limiting example an embodiment.

Sur ce dessin, on a représenté sur une vue en coupe verticale d'ensemble un carter 1, monté sur une semelle 2 par des vis 3, et sur lequel est montée, basculant autour d'un axe 4, une manette de manoeuvre 5. In this drawing, a casing 1 is shown in a vertical sectional view of an assembly, mounted on a soleplate 2 by screws 3, and on which is mounted, rocking about an axis 4, an operating lever 5.

Ce carter présente une fente horizontale 6 dans laquelle la feuille F, le plus souvent en papier, est insérée, comme dans une perforatrice usuelle. This casing has a horizontal slot 6 into which the sheet F, most often made of paper, is inserted, as in a conventional perforator.

Le dispositif selon l'invention comprend les éléments d'une telle perforatrice usuelle, c'est-à-dire une tige 7, jouant le rôle de poinçon, repoussée au repos vers le haut par un ressort de compression 8 prenant appui, en bas, sur le carter 1, et en haut, sur un clip 9 inséré dans une gorge 10 de la tige 7. Sous la manette 5 est montée une calle 11, inclinée vers l'arrière et contre laquelle appuie la tête du poinçon 7. Sous la feuille F, le carter 1 présente une lumière 12 pour le passage du pied (concave) du poinçon 7 quand, comme dans l'opération usuelle d'une perforatrice, le poinçon 7 est enfoncé par la manoeuvre de la manette 5. The device according to the invention comprises the elements of such a conventional perforator, that is to say a rod 7, playing the role of punch, pushed at rest upwards by a compression spring 8 bearing at the bottom , on the casing 1, and at the top, on a clip 9 inserted in a groove 10 of the rod 7. Under the lever 5 is mounted a block 11, inclined backwards and against which the head of the punch 7 presses. the sheet F, the casing 1 has a slot 12 for the passage of the foot (concave) of the punch 7 when, as in the usual operation of a perforator, the punch 7 is pressed in by the operation of the lever 5.

L'ensemble des organes 1-12 constitue une perforatrice du type usuel, permettant de pratiquer dans la feuille F un nombre quelconque de perforations, individuelles ou simultanées avec plusieurs poinçons 7 en parallèle. The set of members 1-12 constitutes a perforator of the usual type, making it possible to practice in the sheet F any number of perforations, individual or simultaneous with several punches 7 in parallel.

L'invention consiste dans l'association, à cette perforatrice, d'un système de renforcement de la feuille F, intervenant au gré de l'opérateur. The invention consists in associating, with this perforator, a system for reinforcing the sheet F, operating at the discretion of the operator.

A cet effet, le carter comporte un logement 100 pour un rouleau 101 de ruban auto-adhésif associé de manière connue à une pellicule de protection 102. To this end, the casing includes a housing 100 for a roll 101 of self-adhesive tape associated in a known manner with a protective film 102.

Ce logement communique par un couloir commun 120, d'une part avecla fente avant 6 précitée, et d'autre part avec un couloir 103, débouchant vers la face arrière du dispositif et servant de guide à un équipage 104, rappelé normalement vers l'avant par un ressort 105 et pouvant être manoeuvré manuellement vers l'arrière par un doigt d'armement 106 sortant du carter 1 le long d'une fenêtre longitudinale 107. This housing communicates by a common corridor 120, on the one hand with the aforementioned front slot 6, and on the other hand with a corridor 103, opening towards the rear face of the device and serving as a guide for a crew 104, normally called towards the front by a spring 105 and capable of being manually maneuvered towards the rear by an arming finger 106 emerging from the casing 1 along a longitudinal window 107.

Cet équipage, comme on le voit sur la figure la comporte un corps 108, prenant appui sur les quatre faces du couloir 103, présentant une fente 109 pour le passage de la pellicule 102, et portant un élément de pincement 110, réuni au corps 108 par une zone souple 111 et présentant un rebord supérieur 112 et un rebord inférieur 113. This equipment, as can be seen in the figure, comprises a body 108, bearing on the four faces of the corridor 103, having a slot 109 for the passage of the film 102, and carrying a pinching element 110, joined to the body 108 by a flexible zone 111 and having an upper rim 112 and a lower rim 113.

Par ailleurs l'équipage 104 porte, dans un logement en queue d'aronde, une butée 114 en caoutchouc ou analogue, faisant face au rebord 113. Furthermore, the crew 104 carries, in a dovetail housing, a stop 114 made of rubber or the like, facing the rim 113.

Enfin la face supérieure du couloir 103 présente un profil en forme de chemin-came, comportant une première pente 115, et une encoche verticale 116, avec lesquelles coopère le rebord 112 au moment de l'armement, vers l'arrière, de l'équipage 104. Finally, the upper face of the corridor 103 has a profile in the form of a cam path, comprising a first slope 115, and a vertical notch 116, with which the flange 112 cooperates at the time of rearward arming of the crew 104.

L'ensemble du dispositif est complété par un système de sectionnement se composant d'une lame 117, normalement repoussée vers le haut par un ressort 118, et actionnée vers le bas par la cale Il, quand la manette 5 est abaissée. Enfin, la base du poinçon 7 porte un tampon de compression en caoutchouc mousse écrasable 119. The entire device is completed by a sectioning system consisting of a blade 117, normally pushed upwards by a spring 118, and actuated downwards by the wedge II, when the lever 5 is lowered. Finally, the base of the punch 7 carries a compression pad made of crushable foam rubber 119.

Le fonctionnement de la portion "renforcement" 100-120 du dispositif est alors le suivant
Le ruban 101-102 ayant déjà été utilisé, tant que cette portion "renforcement" n'est pas armée, seule la portion "perforation" 1-2 intervient, de manière connue.The operation of the “reinforcement” portion 100-120 of the device is then as follows
The ribbon 101-102 having already been used, as long as this “reinforcement” portion is not reinforced, only the “perforation” portion 1-2 intervenes, in known manner.

Si l'on souhaite renforcer la zone de perforation d'une feuille F, il suffit d'armer le dispositif en tirant le doigt 106 vers l'arrière. Dans ce cas, l'ensemble de l'équipage 104 est ramené à l'arrière du carter, en opposition au ressort 105. If it is desired to reinforce the perforation zone of a sheet F, it suffices to arm the device by pulling the finger 106 backwards. In this case, the entire crew 104 is brought to the rear of the casing, in opposition to the spring 105.

Dans ce cas, le rebord 112, rencontrant la pente 115 du chemincame, est rabattu vers le bas autour de la zone souple 111, de sorte que le rebord 113 vient pincer la pellicule 102 contre la butée 114, et, du fait du recul de l'équipage 104, le ruban 101-102 est déroulé d'une longueur correspondant à la longueur de la lumière 107. Or, au point de jonction 121 du couloir 120 avec la fente avant 6, et avec le couloir arrière 103, ledit ruban subit une flexion de presque 3600, alors que, comme il est connu, le ruban auto-adhésif 101 lui-même est relativement rigide. I1 en résulte qu'au point 121, ledit ruban 101 va poursuivre son cheminement horizontal avant, vers et à travers la fente 6, c'est-à-dire sous le poinçon 7, tandis que la pellicule de protection 102 est renvoyée vers l'arrière, pour sortir à l'arrière du carter. Quand le rebord 112 rencontre la pente 116, il se relève et libère la pellicule 102, et quand le doigt 106 est relâché, l'équipage 104 retourne en position de départ, sans entraîner la pellicule 102.In this case, the flange 112, meeting the slope 115 of the chemincame, is folded down around the flexible zone 111, so that the flange 113 comes to pinch the film 102 against the stop 114, and, due to the recoil of the crew 104, the strip 101-102 is unrolled with a length corresponding to the length of the light 107. However, at the junction point 121 of the corridor 120 with the front slot 6, and with the rear corridor 103, said ribbon undergoes a bending of almost 3600, while, as is known, the self-adhesive tape 101 itself is relatively rigid. I1 follows that at point 121, said strip 101 will continue its horizontal path before, towards and through the slot 6, that is to say under the punch 7, while the protective film 102 is returned towards the 'rear, to exit at the rear of the housing. When the rim 112 meets the slope 116, it rises and releases the film 102, and when the finger 106 is released, the crew 104 returns to the starting position, without driving the film 102.

Quand la manette 5 est alors actionnée, non seulement la feuille F est perforée, mais également le ruban 101, qui, simultanément est comprimé par le tampon élastique 119 et par suite fixé contre la feuille F. On obtient donc sur la feuille F une perforation renforcée par un carré de ruban plastique collé automatiquement par la même opération. When the lever 5 is then actuated, not only the sheet F is perforated, but also the tape 101, which simultaneously is compressed by the elastic pad 119 and consequently fixed against the sheet F. A perforation is therefore obtained on the sheet F reinforced by a square of plastic tape glued automatically by the same operation.

On notera que pour assurer un bon fonctionnement de la lame 117 du sectionnement, elle peut être soumise à un élément anti-jeu consistant en une bille 122 appuyée, par un ressort 123 contre la lame 117.  It will be noted that in order to ensure that the blade 117 of the sectioning works properly, it may be subjected to an anti-play element consisting of a ball 122 supported by a spring 123 against the blade 117.
