Abstract

The present invention relates to the field of extrusion devices called extruder guns. According to the invention, improvements to a manual extrusion device, making it possible to prevent subsequent flow, consist of connection means between the trigger 4 and the cock 11 which are formed by a helical spring 42, and of an axial pin 43, the said pin being folded about itself in the shape of a hairpin at one of its ends 44 in order to join one end of the said spring, the hairpin fold being intended to pass through a hole 48 in the trigger, while the other end of the pin is intended to pass through a hole 47 in the handle and through a hole 46 in the cock, behind which the pin will subsequently be curved at approximately 90 DEG . Applications to any extruer gun provided with such a cock.

Description

La présente invention est du domaine des dispositifs d'extrusion à action manuelle et elle a pour objet des perfectionnements à des moyens destinés à éviter l'écoulement subséquent auquel donnent lieu de tels dispositifs, tels que décrits dans la demande FR 82/07607 du même Demandeur. The present invention is in the field of manually acting extrusion devices and its subject is improvements to means intended to avoid the subsequent flow to which such devices give rise, as described in application FR 82/07607 of the same Applicant.

Pour mémoire, la demande précitée décrit un pistolet extrudeur qui est essentiellement cons titué d'un berceau, d'une poignée solidaire du berceau, d'un levier en forme de gâchette articulé sur la poignée et d'une tige en forme de piston comportant à son extrémité antérieure un disque destiné à transmettre l'effort de la tige au fond mobile d'une cartouche disposéedans le berceau, la tige recevant elle-même son effort de la gâchette ; un tel dispositif comportant en outre des moyens pour interdire le retour en arrière de la tige, ces moyens comprenant une pièce dite "chien" sur laquelle une pression volontaire peut être exercée pour autoriser le retour en arrière de la tige. For the record, the aforementioned application describes an extruder gun which is essentially constituted by a cradle, a handle integral with the cradle, a trigger-shaped lever articulated on the handle and a piston-shaped rod comprising at its anterior end a disc intended to transmit the force of the rod to the movable bottom of a cartridge disposed in the cradle, the rod itself receiving its force from the trigger; such a device further comprising means for preventing the backward movement of the rod, these means comprising a so-called "dog" part on which voluntary pressure can be exerted to authorize the return backward of the rod.

On rappelle encore que la demande de brevet principale préconise et décrit des moyens de liaison entre la gâchette et le chien, ces moyens de liaison étant destinés à exercer de façon automatique l'action sur le chien, et à remplacer ainsi l'action volontaire, lorsque a pression manuelle sur la gâchette est totalement relâchée. Il résulte de ces perfectionnements que l'écoulement subséquent est automatiquement évité. It will also be recalled that the main patent application recommends and describes connection means between the trigger and the dog, these connection means being intended to exert the action automatically on the dog, and thus to replace the voluntary action, when manual pressure on the trigger is fully released. It follows from these improvements that the subsequent flow is automatically avoided.

Les présents perfectionnements ont pour objet des moyens de liaison améliorés entre la gâchette et le chien, les améliorations résidant dans un coût de ces truction beaucoup plus faible que celui des moyens précédents et dans une beaucoup plus grande facilité d'adaptation sur les pistolets extrudeurs du genre précité. The present improvements relate to improved means of connection between the trigger and the dog, the improvements residing in a cost of these truction much lower than that of the preceding means and in a much greater ease of adaptation on the extruder guns of the aforementioned genre.

Suivant les présents perfectionnements les moyens de liaison conformes à la présente invention sont caractérisés d'une manière génerale en ce qu'ils sont constitués par une pièce unique formée par un ressort héli cotidal et par une tige occupant une position sensiblement axiale par rapport au ressort, ladite tige étant repliée en épingle sur elle-même à l'une de ses extrémités pour rejoindre une extrémité dudit ressort, le repli en epingle étant destiné à passer à travers un trou de la gâchette tandis que l'autre extrémité de la tige est destinée à passer à travers un trou de la poignée et à travers un trou du chien derriere lequel la tige sera ultérieurement recourbée. According to the present improvements, the connection means in accordance with the present invention are generally characterized in that they consist of a single piece formed by a heli cotidal spring and by a rod occupying a substantially axial position relative to the spring. , said rod being folded in a pin on itself at one of its ends to join one end of said spring, the folded in pin being intended to pass through a hole in the trigger while the other end of the rod is intended to pass through a hole in the handle and through a hole in the dog behind which the rod will later be bent.

Les présents perfectionnements seront mieux compris à la description qui va en être faite en relation avec les figures de la planche unique annexée dans laquelle
- la fig.l est une vue de côté d'un pistolet extrudeur comportant les présents perfectionnements,
- la fig.2 est une coupe partielle longitudinale du même à plus grande échelle, et
- la fig.3 est une illustration en perspective des moyens de liaison isolés dont est pourvu le pistolet des figures précédentes;3a est une variante d'exécution.The present improvements will be better understood from the description which will be given thereof in relation to the figures of the single sheet appended in which
- Fig.l is a side view of an extruder gun comprising the present improvements,
FIG. 2 is a partial longitudinal section of the same on a larger scale, and
- Fig.3 is a perspective illustration of the isolated connecting means which is provided with the gun of the previous figures; 3a is an alternative embodiment.

Sur les fig.l et 2, un pistolet extrudeur de l'invention est essentiellement constitué d'un berceau 1 destiné à recevoir une cartouche 40, d'une poignée 2 solidaire du berceau, d'un levier en forme de gâchette 4 articulé sur la poignée autour d'un axe 3 et d'une tige 7 à fonction de piston ; des moyens 41 d'interdiction du retour en arrière de la tige 7 sont disposés au voisinage de la face arrière de la poignée 2, ils comprennent une pièce 11 dite chien dont le mode d'action a été largement explicité dans l'art antérieur ; on rappelle qu'une action volontaire d'appui sur le chien libère la tige 7 et permet le retour en arrière de celle-ci. In FIGS. 1 and 2, an extruder gun of the invention essentially consists of a cradle 1 intended to receive a cartridge 40, of a handle 2 secured to the cradle, of a trigger in the form of a trigger 4 articulated on the handle around an axis 3 and a rod 7 with a piston function; means 41 for preventing backward movement of the rod 7 are arranged in the vicinity of the rear face of the handle 2, they comprise a part 11 known as a dog, the mode of action of which has been largely explained in the prior art; it is recalled that a voluntary action of support on the dog releases the rod 7 and allows the backward movement of the latter.

Sur les fig.2 et 3, une forme per fectionnée des moyens de liaison entre la gâchette 2 et le chien il comprend un ressort hélicoldal 42 et une tige axiale 43 dont une extrémité 44 est recourbée en épingle pour être raccordée à une extrémité du ressort hélicoïdal tandis que l'autre extrémité 45 peut etre recourbée (45') à environ 90Q.  In fig. 2 and 3, a perfected form of the connection means between the trigger 2 and the dog, it comprises a helical spring 42 and an axial rod 43, one end 44 of which is bent into a pin to be connected to one end of the spring helical while the other end 45 can be bent (45 ') to about 90Q.

L'adaptation d'un moyen de liaison tel que celui de la fig.3, sur des pistolets extrudeurs courants est des plus simples et elle comprend les étapes suivantes : on perce en une même opération un trou 46 dans le chien, un trou 47 dans le dos de la tige et un trou 48 dans la gâchette, la gâchette étant maintenue dans la position comprimée représentée par les pointillés 4' ; après quoi la gâchette 4 étant en position détendue (traits pleins), on introduit l'extrémité 45 de la tige 43 depuis l'intérieur de la poignée dans les trous 47 et 46, on saisit à l'aide d'une pince cette extrémité et l'on comprime le ressort 42 jusqu'à ce que l'épingle 44 soit en regard du trou 48 de la gâchette, on laisse alors le ressort 42 se détendre et les moyens de liaison sont en place ; il suffit alors de recourber l'extrémité 45 en 45' sur une longueur telle que le chien 11 soit légèrement comprimé ; le dispositif conforme aux présents perfectionnements est alors prêt à être utilisé. The adaptation of a connecting means such as that of FIG. 3, on common extruder guns is very simple and it comprises the following stages: a hole 46 is drilled in the same operation in the dog, a hole 47 in the back of the rod and a hole 48 in the trigger, the trigger being held in the compressed position represented by the dotted lines 4 '; after which the trigger 4 is in the relaxed position (solid lines), the end 45 of the rod 43 is introduced from the inside of the handle into the holes 47 and 46, this end is grasped using pliers and the spring 42 is compressed until the pin 44 is opposite the hole 48 of the trigger, the spring 42 is then left to relax and the connection means are in place; it then suffices to bend the end 45 at 45 ′ over a length such that the dog 11 is slightly compressed; the device in accordance with the present improvements is then ready to be used.

Sur la fig.3a, à titre de variante d'exécution des moyens de liaison, la tige 43 et le ressort 44 de la fig.3 ne forment plus ûn ensemble continu obtenu par pliage en 44 mais forment un ensemble dans lequel le ressort 42' et la tige 43' sont raccordés par soudage à leur extrémité 44' ; le résultat est bien entendu-identique à celui de l'ensemble de la fig.3, ces moyens de liaison sont équivalents aux précédents, etleur mise en place sur le pistolet est tout à fait analogue. In Fig.3a, as an alternative embodiment of the connecting means, the rod 43 and the spring 44 of Fig.3 no longer form a continuous assembly obtained by folding at 44 but form an assembly in which the spring 42 'and the rod 43' are connected by welding at their end 44 '; the result is of course-identical to that of the assembly of fig.3, these connecting means are equivalent to the previous ones, and their placement on the gun is quite similar.

On doit comprendre que les moyens de liaison utilisés ci-dessus ne s'appliquent pas seulement aux dispositifs pourvus d'un chien tel que celui de la fig.2, mais à tout dispositif comportant un chien au voisinage de la partie arrière de la poignée comme cela a été illustré sur la fig.l par le rectangle en pointillés.  It should be understood that the connecting means used above do not only apply to devices provided with a dog such as that of FIG. 2, but to any device comprising a dog in the vicinity of the rear part of the handle. as illustrated in fig.l by the dotted rectangle.
