Description

La présente invention concerne le domaine de l'assemblage et du maintien de cadres et autres éléments devant être maintenus par serrage lors de leur assemblage final, généralement par collage, et a pour objet un dispositif pour le serrage et le maintien d'éléments à assembler par collage, agrafage, clouage ou rivetage (voir par exemple DE-C 181 133).The present invention relates to the field of assembling and holding frames and other elements to be held by clamping during their final assembly, generally by bonding, and relates to a device for clamping and holding elements to be assembled by gluing, stapling, nailing or riveting (see for example DE-C 181 133).

Il existe actuellement divers dispositifs de ce type connus sous le terme générique de presse à cadre ou à feuillard qui sont généralement constitués par un ruban de serrage enroulé à une extrémité sur une manivelle et fixé à son autre extrémité dans un axe, qui est, soit un simple axe de maintien, soit un axe d'enroulement et de serrage final du ruban. Il existe également des dispositifs dans lesquels le ruban subit une tension préalable sur les éléments à assembler, puis est bloqué, et son serrage final est réalisé au moyen d'un dispositif annexe de serrage.There are currently various devices of this type known under the generic term of frame or strip press which generally consist of a tightening tape wound at one end on a crank and fixed at its other end in an axis, which is either a simple retaining axis, that is, a winding and final tightening axis of the ribbon. There are also devices in which the ribbon undergoes a prior tension on the elements to be assembled, then is blocked, and its final tightening is carried out by means of an annex clamping device.

Ces dispositifs connus présentent, cependant, l'inconvénient de nécessiter l'actionnement de plusieurs éléments de blocage et/ou de serrage et sont ainsi éventuellement sujet à des risques de mauvais fonctionnement, à savoir notamment un déblocage d'une extrémité du ruban, voire un démontage de l'extrémité du ruban opposée à la bobine d'enroulement, de son axe de maintien.These known devices have, however, the disadvantage of requiring the actuation of several locking and / or clamping elements and are thus possibly subject to risks of malfunction, namely in particular an unlocking of one end of the ribbon, or even disassembly of the end of the ribbon opposite the winding reel, of its retaining pin.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un dispositif pour le serrage et le maintien d'éléments à assembler, par collage, agrafage, clouage, ou rivetage, constitué par un ruban enroulé à une extrémité sur une bobine et fixé à son autre extrémité sur un axe de manoeuvre, l'ensemble étant monté dans un carter de protection, et par des pièces de reprise et de positionnement aux coins, caractérisé en ce que l'axe de manoeuvre est un axe débrayable surmonté d'un bouton de manoeuvre déplaçable sur ledit axe, et pouvant être bloqué dans diverses positions de déplacement sur cet axe, ce bouton de manoeuvre étant muni, en outre, d'un pignon denté pouvant coopérer, dans une position de déplacement du bouton, avec un pignon solidaire de l'axe fendu de la bobine d'enroulement du ruban, et dans une autre position de déplacement du bouton, avec un cliquet chargé par ressort, le ruban enroulé sur la bobine traversant l'axe de manoeuvre qui est fendu à cet effet, de manière à former une boucle sortant du carter.It has, in fact, for its object a device for clamping and holding elements to be assembled, by gluing, stapling, nailing, or riveting, constituted by a ribbon wound at one end on a spool and fixed at its other end on an operating axis, the assembly being mounted in a protective casing, and by recovery and positioning parts at the corners, characterized in that the operating axis is a disengageable axis surmounted by an operating button which can be moved over said axis, and being able to be locked in various displacement positions on this axis, this operating button being provided, moreover, with a toothed pinion which can cooperate, in a position of displacement of the button, with a pinion integral with the axis slit from the ribbon winding reel, and in another position for moving the button, with a spring loaded ratchet, the ribbon wound on the reel crossing the operating axis which is slit for this purpose, so as to fo make a loop coming out of the housing.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel :

  • la figure 1 est une vue en élévation et en coupe du dispositif conforme à l'invention, et
  • la figure 2 est une vue en plan et en coupe suivant A-A.
The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which:
  • FIG. 1 is a view in elevation and in section of the device according to the invention, and
  • Figure 2 is a plan view in section along AA.

Conformément à l'invention, et comme le montrent plus particulièrement les figures 1 et 2 du dessin annexé, le dispositif de serrage et de maintien d'éléments à assembler, qui est essentiellement constitué par un ruban 1 enroulé à une extrémité sur une bobine 2 et fixé à son autre extrémité sur un axe de manoeuvre 3, l'ensemble étant monté dans un carter de protection 4, et par des pièces 5 de reprise et de positionnement aux coins, et caractérisé en ce que l'axe de manoeuvre 3 est sous forme d'un axe débrayable sur lequel est monté, de manière déplaçable, un bouton de manoeuvre 6 qui peut être bloqué dans diverses positions de déplacement sur l'axe 3. Le bouton de manoeuvre 6 est muni, en outre, d'un pignon denté 7 qui peut coopérer, d'une part, dans une position de déplacement du bouton, avec un pignon 8 solidaire de l'axe fendu 9 de la bobine 2 d'enroulement du ruban 1, et, d'autre part, dans une autre position de déplacement du bouton 6, avec un cliquet 10 chargé par un ressort 11. Enfin, le ruban 1, enroulé sur la bobine 2, traverse l'axe de manoeuvre 3, qui présente, à cet effet, une fente 12, de manière à former une boucle 14 sortant du carter 4.According to the invention, and as shown more particularly in Figures 1 and 2 of the accompanying drawing, the device for clamping and holding elements to be assembled, which essentially consists of a tape 1 wound at one end on a spool 2 and fixed at its other end to an operating shaft 3, the assembly being mounted in a protective casing 4, and by parts 5 for recovery and positioning at the corners, and characterized in that the operating axis 3 is in the form of a disengageable axis on which is mounted, in a displaceable manner, an operating button 6 which can be locked in various displacement positions on the axis 3. The operating button 6 is also provided with a toothed pinion 7 which can cooperate, on the one hand, in a position of displacement of the button, with a pinion 8 integral with the split axis 9 of the reel 2 for winding the ribbon 1, and, on the other hand, in another position for moving button 6, with a click quet 10 loaded by a spring 11. Finally, the ribbon 1, wound on the reel 2, crosses the operating shaft 3, which has, for this purpose, a slot 12, so as to form a loop 14 leaving the casing 4 .

Les axes fendus 3 et 9, de manoeuvre et de la bobine 2, sont guidés en rotation entre deux parois du carter 4, qui assurent simultanément le maintien de la bobine 2 et le guidage du ruban 1.The split axes 3 and 9, for maneuvering and for the spool 2, are guided in rotation between two walls of the casing 4, which simultaneously maintain the spool 2 and guide the ribbon 1.

En outre, l'axe de manoeuvre 3 est muni à son extrémité tournée vers le bouton de manoeuvre 6, d'une part, d'un moyen de crabotage mâle 13 coopérant avec un moyen de crabotage femelle 13', de forme correspondante, et, d'autre part, au-dessus du moyen 13, en direction du bouton 6, d'un moyeu 15 de guidage de ce dernier, et le cliquet 10 est monté sur la paroi du carter 4 du côté du moyen 13 de l'axe 3. Ainsi, lorsque le bouton de manoeuvre 6 est en prise d'entraînement avec l'axe 3, son pignon denté 7 est en prise avec le cliquet 10, de sorte que, dans cette position, un seul sens de rotation est possible, l'autre sens étant bloqué par le cliquet 10.In addition, the operating pin 3 is provided at its end facing the operating button 6, on the one hand, with a male clutch means 13 cooperating with a female clutch means 13 ', of corresponding shape, and , on the other hand, above the means 13, in the direction of the button 6, of a hub 15 for guiding the latter, and the pawl 10 is mounted on the wall of the casing 4 on the side of the means 13 of the axis 3. Thus, when the operating button 6 is engaged in drive with the axis 3, its toothed pinion 7 is engaged with the pawl 10, so that, in this position, only one direction of rotation is possible , the other direction being blocked by the pawl 10.

Le pignon 8 de l'axe 9 de la bobine 2 s'étend avantageusement au-dessus du cliquet 10 avec un espacement par rapport à ce dernier au moins égal à 1 épaisseur du pignon 7 du bouton 6, et ce dernier est, soit chargé par un ressort tendant à le maintenir dans l'une de ses positions extrêmes sur le moyeu 15 de l'axe 3, soit muni d'un moyen 16 d'arrêt en position sur le moyeu 15, dans chaque position intermédiaire de déplacement sur l'axe 3, tel qu'un élément d'encliquetage à bille chargée par ressort, ou analogue.The pinion 8 of the axis 9 of the coil 2 advantageously extends above the pawl 10 with a spacing from the latter at least equal to 1 thickness of the pinion 7 of the button 6, and the latter is either loaded by a spring tending to maintain it in one of its extreme positions on the hub 15 of the axis 3, or provided with a stop means 16 in position on the hub 15, in each intermediate position of displacement on the axis 3, such as a spring loaded ball catch, or the like.

Ce mode de réalisation permet, dans le cas d'un bouton 6 chargé par ressort suivant l'une de ses directions de déplacement, de savoir avec certitude dans quelle position se trouve le pignon 7 du bouton 6, à savoir, d'engrènement avec le pignon 8 de l'axe 9 ou avec le cliquet 10, une position intermédiaire entre ces deux permettant la libération de la bobine 2 simultanément à celle de l'axe 3, et, dans le cas d'un bouton 6 muni d'un moyen 16 d'arrêt en position sur le moyeu 15, d'assurer le positionnement exact du bouton 6 dans chaque position extrême et intermédiaire.This embodiment allows, in the case of a button 6 loaded by spring in one of its directions of movement, to know with certainty in which position is the pinion 7 of the button 6, namely, meshing with the pinion 8 of the axis 9 or with the pawl 10, an intermediate position between these two allowing the release of the coil 2 simultaneously with that of the axis 3, and, in the case of a button 6 provided with a stop means 16 in position on the hub 15, to ensure the exact positioning of the button 6 in each extreme and intermediate position.

Les brins de la boucle 14 sortant du carter 4 sont guidés entre un élément 17 d'écartement, faisant partie du carter 4 et formant simultanément un angle de reprise et de positionnement pour un coin des éléments à assembler, et deux cylindres 18 solidaires du carter 4, de telle manière que chaque brin passe entre un cylindre 18 et l'élément 17, et, à la sortie des brins de la boucle 14, le carter 4 est muni, en outre, d'une empreinte multiple 19 consistant en plusieurs segments d'inclinaison différente par rapport à la face du carter et permettant l'appui d'éléments à abouter suivant divers angles. En outre, l'empreinte multiple 19, ainsi que les pièces 5 de reprise et de positionnement aux coins, sont avantageusement pourvus d'au moins un rebord de guidage du ruban 1, les pièces 5 pouvant être munies, en outre, d'un segment élastique vertical 20 destiné à enserrer le ruban 1.The strands of the loop 14 leaving the casing 4 are guided between a spacer element 17, forming part of the casing 4 and simultaneously forming a recovery and positioning angle for a corner of the elements to be assembled, and two cylinders 18 solidai res of the casing 4, such that each strand passes between a cylinder 18 and the element 17, and, at the outlet of the strands of the loop 14, the casing 4 is further provided with a multiple imprint 19 consisting in several segments of different inclination relative to the face of the casing and allowing the support of elements to abut at various angles. In addition, the multiple imprint 19, as well as the parts 5 for taking up and positioning at the corners, are advantageously provided with at least one edge for guiding the ribbon 1, the parts 5 being able to be provided, in addition, with a vertical elastic segment 20 intended to grip the ribbon 1.

Enfin, la bobine 2 est chargée par un ressort à lame 21 de maintien du ruban 1.Finally, the coil 2 is loaded by a leaf spring 21 for holding the ribbon 1.

Le dispositif conforme à l'invention fonctionne suivant la manière suivante :The device according to the invention operates in the following manner:

Par déplacement du bouton 6 dans une position intermédiaire, dans laquelle son pignon 7 se trouve entre le pignon 8 de l'axe 9 et le cliquet 10,c'est-à-dire dans laquelle la bobine 9 et l'axe 3 sont libres en rotation, le ruban 1 peut être déroulée de la bobine 2 à travers la fente 12 de l'axe de manoeuvre 3 de manière à permettre une ouverture de la boucle 14 suffisante pour assurer le montage autour des éléments à assembler, par exemple pour former un cadre. Les pièces 5 sont alors enfilées par leur segment vertical 20 sur le ruban 1 et placées aux coins du cadre, ou analogue, à réaliser, et le bouton 6 est déplacée dans une position extrême dans laquelle son pignon denté 7 est en contact avec le pignon 8 de l'axe 9 de la bobine 2. Par rotation du bouton 6, le ruban 1 est alors réenroulé sur la bobine 2 jusqu'à obtention d'une faible tension, puis le bouton 6 est déplacé sur le moyeu 15 de l'axe 3 afin d'amener son crabotage femelle 13' en coopération de forme avec le crabotage mâle 13 dudit axe 3. Par poursuite de la rotation du bouton 6 dans le même sens que lors de l'enroulement du ruban 1 sur la bobine 2, le serrage définitif des éléments à assembler est réalisé, par avance simultanée des deux brins du ruban, ce serrage étant maintenu par blocage de l'axe 3, par coopération du cliquet 10 avec le pignon denté 7 du bouton 6. Lors de cette dernière opération, le ruban 1, dont une extrémité est fixée sur l'axe de manoeuvre 3 et qui traverse, en outre, la fente 12 de ce dernier, est enroulé, simultanément avec l'extrémité fixée à l'axe 3, sur ce dernier, de sorte que la boucle 14 formée à l'extérieur du carter est tendue simultanément et de manière égale, par ses deux brins pénétrant dans le carter 4. La partie du ruban 1 s'étendant entre la bobine 2 et l'axe 3 peut s'enrouler, alors, librement autour de l'axe 3, du fait que l'axe 9 de la bobine 2 n'est plus chargé d'aucune manière.By displacement of the button 6 in an intermediate position, in which its pinion 7 is located between the pinion 8 of the axis 9 and the pawl 10, that is to say in which the coil 9 and the axis 3 are free in rotation, the ribbon 1 can be unwound from the reel 2 through the slot 12 of the operating shaft 3 so as to allow opening of the loop 14 sufficient to ensure mounting around the elements to be assembled, for example to form a frame. The parts 5 are then threaded by their vertical segment 20 onto the ribbon 1 and placed at the corners of the frame, or the like, to be produced, and the button 6 is moved to an extreme position in which its toothed pinion 7 is in contact with the pinion 8 of the axis 9 of the reel 2. By rotation of the button 6, the ribbon 1 is then rewound on the reel 2 until a low tension is obtained, then the button 6 is moved on the hub 15 of the axis 3 in order to bring its female clutch 13 'in shape cooperation with the male clutch 13 of said axis 3. By continuing to rotate the button 6 in the same direction as during the winding of the ribbon 1 on the reel 2, the final tightening of the elements to be assembled is carried out, by simultaneous advance of the two strands of the ribbon, this tightening being maintained by locking the axis 3, by cooperation of the pawl 10 with the toothed pinion 7 of the button 6. During this last operation , the ribbon 1, one end of which is fixed to the a xe of maneuver 3 and which also crosses the slot 12 of the latter, is wound, simultaneously with the end fixed to the axis 3, on the latter, so that the loop 14 formed outside the casing is stretched simultaneously and equally, by its two strands penetrating into the casing 4. The part of the ribbon 1 extending between the coil 2 and the axis 3 can be wound, then, freely around the axis 3, because the axis 9 of the coil 2 is no longer loaded in any way.

Pour réaliser un déblocage de la boucle 14, il suffit de tourner légèrement le bouton 6 et de le déplacer simultanément sur l'axe 3 de manière à dégager le cliquet 10 des dents du pignon 7 et à interrompre la liaison de crabotage entre les moyens 13 et 13' . Dans la position intermédiaire du bouton 6 ou dans sa position de liaison avec la bobine 2 par l'intermédiaire des pignons 7 et 8, l'axe 3 est alors totalement libre en rotation, et une traction sur les brins de la boucle 14 permet de libérer les éléments serrés au moyen du dispositif.To release the loop 14, it suffices to slightly turn the button 6 and simultaneously move it on the axis 3 so as to disengage the pawl 10 from the teeth of the pinion 7 and to interrupt the clutch connection between the means 13 and 13 '. In the intermediate position of the button 6 or in its position of connection with the coil 2 via the pinions 7 and 8, the axis 3 is then completely free to rotate, and a traction on the strands of the loop 14 makes it possible to release the tightened elements by means of the device.

Le dispositif décrit ci-dessus l'a été plus particulièrement comme dispositif de serrage d'éléments à assembler, toutefois, il est également utilisable, de manière simple et rationnelle, comme sangle de serrage.The device described above has been more particularly as a device for tightening elements to be assembled, however, it is also usable, in a simple and rational manner, as a tightening strap.

Grâce à l'invention, il est possible de réaliser un dispositif permettant de réaliser le maintien et le serrage d'éléments à assembler entre-eux,en assurant, lors du serrage, une bonne répartition de l'effort de serrage par avance simultanée des deux brins de la boucle enserrant lesdits éléments à assembler. En outre, ce dispositif est de constitution particulièrement simple et présente un minimum de pièces de manoeuvre,de sorte que sa fiabilité est augmentée par rapport aux dispositifs connus de ce type.Thanks to the invention, it is possible to produce a device making it possible to hold and tighten elements to be assembled together, while ensuring, during tightening, a good distribution of the tightening force by simultaneous advance of the two strands of the loop enclosing said elements to be assembled. In addition, this device is of particularly simple constitution and has a minimum of operating parts, so that its reliability is increased compared to known devices of this type.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention, comme il est défini dans la revendication indépendante.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention, as defined in the independent claim.
