Abstract

The feed advances a stick of adhesive to be liquified by electric heating. It has two elements, one on a pivot. On one side is a trigger and, on the opposite side, a rigid fork piece gripping a hollow cylinder. The cylinder has a collar shoulder and two flexible tongues are fixed in it and on part of the cylinder. The collar exterior has a chamfer on which the fork ends press. The trigger advances the stick and returns it on trigger release, actuated by a spring.

Description

On connaît depuis longtemps les distributeurs de colle, appelés aussi pistolets" à colle dans lesquels un bâton de colle cylindrique est liquéfié par chauffage d'uncrésistance électrique. Dans certains modèles c'est la "gachette" qui établit le contact sur la résistance de chauffage. Glue dispensers have been known for a long time, also called "glue guns" in which a stick of cylindrical glue is liquefied by heating an electrical resistance. In certain models it is the "trigger" which establishes the contact on the heating resistance .

L'avancement du bâton de colle est fait par la pression du pouce de l'utilisateur.The advancement of the glue stick is done by the pressure of the user's thumb.

Des modèles plus élaborés comportent un thermostat monté en série avec la résistance pour régulariser la température de la colle afin de la maintenir en état de liquéfaction sans que des températures excessives puissent être atteintes. Par un système mécanique la gachette provoque l'avancement du bâton de colle ce qui régularise l'émission de colle liquide au fur et à mesure des besoins. Ce système comporte malheureusement de nombreuses pièces mobiles, au montage délicat et dont le bon fonctionnement dépend essentiellement de la propreté puisque des traces de colle suffisent à le perturber. More elaborate models include a thermostat mounted in series with the resistance to regulate the temperature of the adhesive in order to maintain it in a liquefaction state without excessive temperatures being reached. By a mechanical system the trigger causes the advancement of the glue stick which regulates the emission of liquid glue as and when required. Unfortunately, this system has many moving parts, delicate assembly and whose proper functioning depends mainly on cleanliness since traces of glue are enough to disturb it.

La présente invention concerne un nouveau mécanisme simplifié d'avancement du bâton de colle. Plus facile à monter et à entretenir, il ne comporte que deux pièces mobiles; dont l'une, articulée sur un pivot, est terminée, d'un côté, par la gachette et, de l'autre, par un étrier qui, sur déplacement de la gachette fait avancer la seconde pièce en forme de cylindre où passe le bâton de colle, en l'entrainant. Des moyens sont prévus pour s'opposer au recul du bâton de colle lors du retour du mdcanisme au repos quand la pression exercée sur la gachette est interrompue, l'un de ces moyens pouvant être constitué par un joint torique retenant le bâton de colle cylindrique. The present invention relates to a new simplified mechanism for advancing the glue stick. Easier to assemble and maintain, it only has two moving parts; one of which, articulated on a pivot, is terminated, on one side, by the trigger and, on the other, by a stirrup which, upon displacement of the trigger advances the second cylinder-shaped part through which the glue stick, training it. Means are provided to oppose the retreat of the glue stick when the mechanism returns to rest when the pressure exerted on the trigger is interrupted, one of these means can be constituted by an O-ring retaining the cylindrical glue stick .

Des dessins sont fournis à titre d'illustration pour montrer le fonctionnement du mécanisme: - La figure 1 montre le corps du pistolet (A) représenté en tirets, avec la première pièce représentée en plan et gros trait, articulée sur un pivot (1) avec la gachette (2) sur laquelle s'excerce les pressions du doigt de l'utilisateur à l'encontre d'un ressort à boudin (B). L'étrier (3) dont la position est située en arrière du pivot d'articulation, se déplace alors dans le sens de la flèche, entrainant la seconde pièce (4), en forme de cylindre, guidée dans un logement (C) du corps du pistolet (A). Drawings are provided by way of illustration to show the operation of the mechanism: - Figure 1 shows the body of the pistol (A) represented in dashes, with the first part shown in plan and large line, articulated on a pivot (1) with the trigger (2) on which the pressure of the user's finger is exerted against a coil spring (B). The stirrup (3), the position of which is located behind the articulation pivot, then moves in the direction of the arrow, driving the second part (4), in the form of a cylinder, guided in a housing (C) of the gun body (A).

- La figure 2 représente cette pièce cylindrique (4) qui est terminée, d'un seul côté, par une collerette (6) sur laquelle vient s'excercer la pression de l'étrier. Deux languettes flexibles sont découpées, de part et d'autre, dans le cylindre, la seconde exactement en dessous de celle représentée (7) est invisible sur cette figure.- Figure 2 shows this cylindrical part (4) which is terminated, on one side, by a flange (6) on which is exerted the pressure of the stirrup. Two flexible tabs are cut on each side in the cylinder, the second exactly below that shown (7) is invisible in this figure.

- La figure 3 montre la seconde pièce présentée du côté de sa collerette (6) et les deux languettes flexibles (7) découpées dans cette pièce.- Figure 3 shows the second part presented on the side of its flange (6) and the two flexible tabs (7) cut from this part.

- La figure 4 représente une coupe selon A-A de la figure 1 montrant en détail les languettes et les extrémités des branches de l'étrier.- Figure 4 shows a section along A-A of Figure 1 showing in detail the tabs and the ends of the legs of the stirrup.

Ces languettes comportent chacune un méplat (5). L'écartement entre les méplats de ces deux languettes est légèrement inférieur au corps du cylindre et à celui des branches de l'étrier auxquelles elles servent de logement de repos. Quand une pression est exercée sur la gachette et que l'étrier vient appuyer sur la collerette, il. appuie en même temps sur les chanfreins (8) faisant flèchir les languettes vers l'intérieur du cylindre contenant le bâton de colle (E) qui, pincé entre elles, est entrainé'obligatoiremcnt, dans le sens de la flèche de la figure 1, vers le canon chauffant (F). Quand la pression sur la gachette est relâchée; l'étrier revient en arrière des chanfreins libérant le bâton de colle, les branches de l'étrier enserrant les méplats ramènent par appui sur les butées (9) le cylindre en arrière (sens inverse de la flèche de la fig. 1) prèt pour une nouvelle impulsion. Un joint torique l10) placé dans un logement (D) prévu pour lui dans le boitier (A), joint ayant un diamètre intérieur légèrement inférieur au diamètre du bâton de colle (E) s'oppose à son recul. Le bâton de colle ne peut donc aller que dans un sens. I1 sera remplacé dès que le joint torique sera vide. These tabs each have a flat (5). The spacing between the flats of these two tabs is slightly less than the body of the cylinder and that of the legs of the stirrup to which they serve as a rest housing. When a pressure is exerted on the trigger and that the stirrup comes to press on the collar, it. presses at the same time on the chamfers (8) causing the tongues to bend towards the inside of the cylinder containing the glue stick (E) which, pinched between them, is driven obligatorily in the direction of the arrow in FIG. 1, towards the heating gun (F). When the pressure on the trigger is released; the stirrup goes back behind the chamfers releasing the glue stick, the branches of the stirrup enclosing the flats bring back by pressing on the stops (9) the cylinder back (opposite direction of the arrow of fig. 1) ready for a new impulse. An O-ring 110) placed in a housing (D) provided for it in the housing (A), a joint having an internal diameter slightly less than the diameter of the glue stick (E) opposes its retreat. The glue stick can therefore only go one way. It will be replaced as soon as the O-ring is empty.
