Description

L'invention concerne un outil de fixation à main du type cloueur, agrafeuse, par exemple.The invention relates to a hand fixing tool of the type nailer, stapler, for example.

Un tel outil comporte, ce qu'on peut appeler, un moteur de propulsion, agencé pour entraîner en déplacement, sous l'action de la mise à feu d'un combustible (gaz ou poudre, notamment), un piston (ou une masselotte) pourvu d'une tige d'entraînement d'un élément de fixation dans un matériau support.Such a tool comprises, what may be called a propulsion engine, arranged to drive in motion, under the action of the firing of a fuel (gas or powder, in particular), a piston (or a flyweight). ) provided with a driving rod of a fastening element in a support material.

A l'avant de l'outil se trouve un guide-tampon dans lequel est placé l'élément de fixation à entraîner. La mise à feu ne peut intervenir qu'après mise en appui de l'outil, par l'intermédiaire du guide-tampon, contre le matériau support.At the front of the tool is a buffer guide in which is placed the fastener to be driven. The firing can only take place after the tool has been supported by means of the buffer guide against the support material.

La profondeur de pénétration de l'élément de fixation dans le matériau support dépend de sa longueur et de la longueur de la tige de piston qui dépasse hors du guide-tampon à la fin du tir. On conçoit donc qu'on ait voulu régler cette longueur de dépassement en fonction précisément de la longueur de l'élément de fixation, du désir de noyer sa tête dans le matériau support, de la volonté de ne pas éclater l'accessoire, s'il s'agit d'en fixer un au matériau support, ou encore et par exemple, de l'attention portée à ne pas éclater le matériau support, à ne pas former de zone épaufrée.The depth of penetration of the fastener into the support material depends on its length and the length of the piston rod protruding out of the buffer guide at the end of the shot. It is therefore conceivable that we wanted to adjust this length of overtaking function precisely the length of the fastener, the desire to drown his head in the support material, the desire not to burst the accessory, s' it is to attach one to the support material, or for example, attention to not burst the support material, not to form a sponged area.

On a donc déjà proposé des dispositifs de réglage du dépassement de la tige de masselotte mais qui sont très complexes. Après avoir soulevé une première pièce, on doit dévisser deux vis, bouger une clavette, revisser les vis et remettre la pièce, tout cela avec des outils.We have already proposed devices for adjusting the overrun of the feeder rod but which are very complex. After having lifted a first part, one must unscrew two screws, move a key, screw the screws and put back the piece, all with tools.

L'invention vise donc à proposer un outil avec un dispositif de réglage particulièrement simple.The invention therefore aims to provide a tool with a particularly simple adjustment device.

Ainsi l'invention concerne un
outil de fixation à main, comprenant un moteur de propulsion d'une masselotte comportant une tige d'entraînement d'un élément de fixation dans un matériau support et à travers un guide-tampon, avec des moyens de réglage du dépassement de la tige de masselotte hors du guide-tampon en fin de propulsion et à l'arrêt de la masselotte en butée contre des moyens d'arrêt, caractérisé par le fait que le guide-tampon est monté libre en translation et les moyens de réglage du dépassement comprennent une molette de réglage avec un arbre de molette agencé pour être en appui contre le guide-tampon et pousser le guide-tampon vers l'avant sous l'action de la rotation de la molette.Thus the invention relates to a
hand-held attachment tool, comprising a feeder motor of a feeder comprising a driving rod of a fastener element in a support material and through a buffer guide, with means for adjusting the extension of the rod of a flyweight outside the buffer guide at the end of propulsion and at stopping the counterweight abutting against stopping means, characterized in that the buffer guide is mounted free in translation and the overrunning adjustment means comprise a adjusting wheel with a wheel shaft arranged to bear against the buffer guide and push the buffer guide forward under the action of the rotation of the wheel.

La position de la masselotte dans l'outil en fin de propulsion, après tir, étant prédéterminée par les moyens d'arrêt, plus on pousse le guide-tampon vers l'avant, plus on réduit la longueur de dépassement de la tige de masselotte.The position of the weight in the tool at the end of propulsion, after firing, being predetermined by the stopping means, the further the buffer guide is pushed forward, the more the length of the oversize of the flyweight rod is reduced. .

On remarquera que si l'opérateur, après un tir, constate qu'il a trop tourné la molette, avant le tir suivant, il tournera la molette dans l'autre sens et, lors de la nouvelle mise en appui de l'outil, le guide-tampon reculera pour se placer en appui contre l'arbre de molette dans une meilleure position.Note that if the operator, after a shot, finds that he has turned too much the wheel, before the next shot, he will turn the wheel in the other direction and, when the new support of the tool, the buffer guide will move back to rest against the wheel shaft in a better position.

On notera que l'outil de la demande EP 1934018 comporte également un moyen de réglage de la profondeur d'entraînement, avec aussi une molette de réglage. Mais cette molette coopère directement avec une tige de palpeur, aussi bien dans un sens que dans l'autre, la portion de tige du palpeur coopérant avec la molette étant filetée pour obtenir des réglages très fins. US 5385 286 enseigne un moyen de réglage de profondeur un peu du même genre.Note that the demand tool EP 1934018 also includes means for adjusting the driving depth, also with a control wheel. But this wheel cooperates directly with a probe rod, both in one direction than in the other, the probe portion of the probe cooperating with the wheel being threaded to obtain very fine adjustments. US 5385286 teaches a depth adjustment means a bit of the same kind.

Dans la forme de réalisation préférée de l'outil de l'invention, le moteur de propulsion est un moteur à combustion interne à combustible fluide et il est prévu une chambre de combustion qui peut être fermée par l'intermédiaire d'une cage montée coulissante par un étrier de cage sur un canon de l'outil dans lequel le guide-tampon est monté coulissant, la chambre et la cage étant solidaires l'une de l'autre, la molette de réglage étant montée rotative sur l'étrier de cage.In the preferred embodiment of the tool of the invention, the propulsion engine is a fluid fuel internal combustion engine and there is provided a combustion chamber which can be closed by means of a sliding mounted cage by a cage stirrup on a barrel of the tool in which the buffer guide is slidably mounted, the chamber and the cage being secured to one of the other, the adjustment wheel being rotatably mounted on the cage stirrup.

Avantageusement, l'arbre de molette s'étend à travers un pont de l'étrier de cage et l'entraînement en rotation de la molette entraîne l'arbre de molette en translation à travers le pont de l'étrier de cage.Advantageously, the wheel shaft extends through a bridge of the cage stirrup and the rotary drive of the wheel drives the wheel shaft in translation through the bridge of the cage stirrup.

De préférence, l'extrémité antérieure de l'arbre de molette comporte un rebord d'appui postérieur contre l'étrier de cage.Preferably, the front end of the wheel shaft has a posterior support flange against the cage caliper.

La molette de réglage peut comporter une portion de disque d'indexage en rotation agencée pour coopérer élastiquement avec l'étrier de cage.The adjustment wheel may comprise a rotational indexing disc portion arranged to cooperate elastically with the cage stirrup.

L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée de l'outil de l'invention, en référence au dessin en annexe, sur lequel

  • la figure 1 est une vue en perspective de la partie antérieure de l'outil, à l'état fermé, en fin de propulsion de la masselotte après tir, sans dépassement de la masselotte hors du guide tampon;
  • la figure 2 est une vue de l'outil similaire à celle de la figure 1, mais avec une coupe axiale d'un quart et
  • la figure 3 est une vue de l'outil similaire à celle de la figure 1, mais avec un dépassement de la masselotte hors du guide-tampon.
The invention will be better understood with the aid of the following description of the preferred embodiment of the tool of the invention, with reference to the appended drawing, in which
  • the figure 1 is a perspective view of the front part of the tool, in the closed state, at the end of propulsion of the weight after firing, without exceeding the weight off the buffer guide;
  • the figure 2 is a view of the tool similar to that of the figure 1 but with an axial cut of a quarter and
  • the figure 3 is a view of the tool similar to that of the figure 1 , but with an overflow of the weight out of the buffer guide.

L'outil à main qui va maintenant être décrit est un cloueur dit à gaz, c'est-à-dire qu'il comporte une chambre de combustion dans laquelle un mélange de combustible, donc ici gazeux, et de comburant, l'air, est mis à feu pour propulser vers l'avant un piston, ou une masselotte 1 qui, à son tour, entraîne un élément de fixation, en l'occurrence un clou, dans un matériau support. La masselotte 1 comporte une tête 2 et une tige 3. La tête 2 est montée mobile en translation sous l'action de la mise à feu du mélange dans un cylindre 4 jusqu'à venir en butée contre un amortisseur d'arrêt 5. Avant la mise à feu, la chambre de combustion est fermée par déplacement d'une cage 6, dont elle est solidaire et qui est prolongée par des bras 7 fixés à un étrier 8. La tige de masselotte 3 est montée mobile en translation dans un canon 9 qui se prolonge vers l'avant par un guide-tampon 10 ici télescopique, monté libre en translation dans le canon 9, et dans lequel on a préalablement au tir introduit un clou. L'étrier de cage 8 est monté coulissant autour du canon 9. L'outil comporte une molette 11 de réglage du dépassement de l'extrémité avant 30 de la tige de masselotte 3 hors de l'extrémité avant 100 du guide-tampon 10, dépassement réglé après le tir, en fin de propulsion, masselotte arrêtée avec sa tête 2 en butée contre l'amortisseur 5. Sur les figures 1 et 2, ce dépassement a été réglé à une valeur nulle.The hand tool that will now be described is a nailer said gas, that is to say it comprises a combustion chamber in which a mixture of fuel, so here gaseous, and oxidizer, air , is fired to propel forwards a piston, or a feeder 1 which, in turn, drives a fastener, in this case a nail, in a carrier material. The weight 1 comprises a head 2 and a rod 3. The head 2 is mounted movable in translation under the action of the firing of the mixture in a cylinder 4 to abut against a stop buffer 5. Before the firing, the combustion chamber is closed by moving a cage 6, which it is secured and which is extended by arms 7 attached to a stirrup 8. The flyweight rod 3 is mounted movably in translation in a barrel 9 which extends forward by a buffer guide 10 here telescopic, mounted freely in translation in the barrel 9, and in which one has before shooting introduces a nail. The cage stirrup 8 is slidably mounted around the barrel 9. The tool comprises a knob 11 for adjusting the protrusion of the front end 30 of the counterweight rod 3 out of the front end 100 of the buffer guide 10. overrun adjusted after firing, at the end of propulsion, counterweight stopped with its head 2 in abutment against the fender 5. On Figures 1 and 2 this overshoot has been set to zero.

La molette 11 est montée rotative entre un pont arrière 12 et un pont avant 13 de l'étrier de cage 8 servant de paliers pour un arbre de molette, portion d'arbre arrière 14 et portion d'arbre avant 15. La portion arrière 14 de l'arbre de molette sert de guide à un ressort 16 de butée de chambre et évite que ce ressort ne flambe, la butée de chambre intervenant à la fermeture de la chambre lors de la mise en appui de l'outil ainsi qu'à l'ouverture de la chambre.The wheel 11 is rotatably mounted between a rear axle 12 and a front axle 13 of the caliper 8 serving as bearings for a wheel shaft, rear shaft portion 14 and front shaft portion 15. The rear portion 14 the wheel shaft serves as a guide to a spring 16 chamber stop and prevents this spring flames, the chamber stop intervening at the closing of the chamber when the support of the tool as well as the opening of the room.

La portion d'arbre avant 15 de la molette 11 comporte, à sont extrémité, un disque 17 de poussée du guide-tampon 10, disque dont le bord périphérique forme rebord 18 d'appui postérieur contre le pont avant 13 de l'étrier de cage 8. Pour coopérer avec le disque de poussée 17 de l'arbre de molette 15, le guide-tampon comporte une jambe 19 se terminant à l'arrière par un disque d'appui 20 destiné à recevoir la poussée du disque 17 de l'arbre de molette 15.The front shaft portion 15 of the wheel 11 comprises, at its end, a thrust disk 17 of the buffer guide 10, disk whose peripheral edge forms a flange 18 of posterior support against the front bridge 13 of the caliper of cage 8. To cooperate with the thrust disk 17 of the wheel shaft 15, the buffer guide comprises a leg 19 ending at the rear by a support disk 20 intended to receive the thrust of the disk 17 of the wheel shaft 15.

La molette de réglage 11 est en partie fendue transversalement pour présenter, à l'avant, un disque d'indexage 21 réuni élastiquement au reste de la molette en ce sens que le disque 21 peut-être déformé vers l'arrière, contre la partie principale de la molette, pour réduire la largeur de la fente et le sortir d'une position d'indexage. En effet, le disque d'indexage 21 de la molette 11 comporte un bossage 22 en saillie axiale prévu pour venir se loger dans un évidement correspondant 23 du pont avant 13 de l'étrier de cage 8.The adjustment wheel 11 is partly split transversely to present, at the front, an indexing disc 21 elastically joined to the rest of the wheel in that the disc 21 may be deformed rearwardly, against the part wheel, to reduce the width of the slot and remove it from an indexing position. Indeed, the indexing disk 21 of the wheel 11 comprises a boss 22 projecting axially intended to be housed in a corresponding recess 23 of the front bridge 13 of the cage stirrup 8.

Quand on tourne la molette 11, l'arbre de molette est entraîné en translation vers l'avant pour entraîner également le guide-tampon 10 vers l'avant, par l'intermédiaire du disque de poussée 17 de la portion d'arbre avant 15 de la molette, du disque d'appui 20 de la jambe 19 du guide-tampon 10 et à travers le pont avant 13 de l'étrier de cage 8.When turning the knob 11, the wheel shaft is translationally driven forward to also drive the buffer guide 10 forward through the thrust disk 17 of the portion. front shaft 15 of the wheel, the support disc 20 of the leg 19 of the buffer guide 10 and through the front bridge 13 of the cage stirrup 8.

Différentes possibilités peuvent être envisagées pour déplacer l'arbre de molette en translation quand on fait tourner la molette. La portion d'arbre avant 15 peut être filetée et le pont avant 13 de l'étrier de cage 8 peut être taraudé, l'arbre étant entraîné en rotation par la molette 11 par l'intermédiaire de méplats, cannelures, carrés ou autre goupille. On pourrait également prévoir des moyens équivalents, par exemple un doigt, sur l'un ou sur l'autre des deux éléments d'arbre et de pont, guidé dans un chemin de guidage sur l'autre des deux éléments.Different possibilities can be envisaged for moving the wheel shaft in translation when the wheel is rotated. The front shaft portion 15 may be threaded and the front bridge 13 of the cage stirrup 8 may be threaded, the shaft being rotated by the wheel 11 through flats, flutes, squares or other pin . One could also provide equivalent means, for example a finger, on one or the other of the two shaft elements and bridge, guided in a guide path on the other of the two elements.

Ainsi la molette 11, par l'intermédiaire de la portion d'arbre avant 15, avec son disque de poussée 17, permet de pousser la jambe 19 du guide-pointe 10 vers l'avant et de régler l'écart entre les plans transversaux d'extrémité de l'extrémité avant 100 du guide-pointe et de la tige de masselotte 3. A nouveau, un trop grand déplacement du guide-tampon vers l'avant pourra être rattrapé lors de la mise en appui suivante de l'outil.Thus, the wheel 11, via the front shaft portion 15, with its thrust plate 17, makes it possible to push the leg 19 of the guide-tip 10 forwards and to adjust the distance between the transverse planes. end of the front end 100 of the tip guide and the feeder pin 3. Again, too great a displacement of the buffer guide forward may be caught when the next support of the tool .

Sur les figures 1 et 2, le dépassement de la tige de masselotte 3 hors du guide-tampon a été réglé à une valeur nulle.On the Figures 1 and 2 , exceeding the weight rod 3 out of the buffer guide has been set to zero.

Sur la figure 3, sur laquelle les mêmes références désignent les mêmes éléments que sur les figures 1 et 2, la tige de masselotte 3, en fin de propulsion et à l'arrêt, fait saillie hors du guide-tampon d'une petite distance axiale d, obtenu par un entraînement en rotation plus poussé de la molette 11.On the figure 3 , on which the same references designate the same elements as on the Figures 1 and 2 , the flyweight rod 3, at the end of propulsion and at a standstill, protrudes out of the buffer guide by a small axial distance d, obtained by further driving the wheel 11.

On remarquera que pour tourner la molette 11 dans un sens ou dans l'autre, il suffit de repousser le disque d'indexage 21, vers l'arrière et de commencer à faire tourner la molette. Les positions d'indexage de la molette dépendent du nombre de bossages 22 sur le disque 21, et du nombre d'évidements 23 dans le pont avant 13 de l'étrier de cage 8.Note that to turn the wheel 11 in one direction or the other, simply push the indexing disc 21 backwards and begin to turn the wheel. The indexing positions of the wheel depend on the number of bosses 22 on the disc 21, and the number of recesses 23 in the front bridge 13 of the cage stirrup 8.
