Abstract

The safeguard device provides an annular part (12) which can be slipped over the nozzle (11) of the sprayer, and a fin (flange) (13), rigidly fastened to the annular part (12) and extending substantially at right angles to the axis of this component. The fin (13) has a weakened area (14) transversely subdividing it into two parts, one (15) near the annular part and the other (16) far from the annular part. The far part has a shaped projection (18) capable of being coupled, by a snap-fitting (latching) mechanism, with an orifice (20) on the detent lever (3), the whole assembly being such that the first actuation of the detent lever separates the far part after the rupture of the fragile area.

Description

DISPOSITIF DE GARANTIE POUR
PULVERISATEURS DE LIQUIDES ACTIONNES
MANUELLEMENT PAR LEVIER A DETENTE.GUARANTEE DEVICE FOR
SPRAYERS OF ACTUATED LIQUIDS
MANUALLY BY RELAXING LEVER.

La présente invention se réfère à un dispositif de garantie destinée à éviter une utilisation abusive des pulvérisateurs de liquides actionnés manuellement par un levier à détente. The present invention refers to a guarantee device intended to prevent misuse of liquid sprayers actuated manually by a detent lever.

Les pulvérisateurs de liquides actionnés par un levier à détente sont connus depuis longtemps et servent, accouplés à un récipient contenant le liquide, par exemple pour nettoyage des surfaces, à pulvériser le liquide sur la surface. De tels pulvérisateurs comprennent essentiellement une pompe alternative, commandée par un levier à détente et associée à des soupapes de refoulement et d'aspiration. La pompe aspire le liquide du récipient à travers un tube plongeur et le renvoie sous pression à une buse de laquelle il ressort sous forme de brouillard. Liquid sprayers actuated by a detent lever have been known for a long time and are used, coupled to a container containing the liquid, for example for cleaning surfaces, to spray the liquid on the surface. Such sprayers essentially include a reciprocating pump, controlled by an expansion lever and associated with discharge and suction valves. The pump draws the liquid from the container through a dip tube and returns it under pressure to a nozzle from which it emerges as a mist.

Le problème qui se pose selon l'invention est de prévoir pour de tels pulvérisateurs un dispositif de garantie apte à signaler immédiatement si une utilisation abusive du pulverisateur a été faite. The problem which arises according to the invention is to provide for such sprayers a guarantee device capable of immediately signaling whether excessive use of the sprayer has been made.

Le problème posé est résolu en prévoyant un organe constitué par une partie annulaire pouvant s'enfiler sur la buse et d'une ailette, solidaire de celle-ci et s'étendant sensiblement à angle droit par rapport à l'axe de cette pièce, l'ailette présentant une zone affaiblie transversalement la subdivisant en deux parties, l'une voisine, l'autre distante de la partie annulaire, la partie distante présentant une saillie de forme, apte à s'accoupler par encliquetage avec un orifice du levier à détente, le tout de manière que la première mise en action du levier à détente sépare la partie distante par suite de la rupture de la zone fragile.  The problem posed is resolved by providing a member constituted by an annular part which can be threaded onto the nozzle and by a fin, integral with the latter and extending substantially at right angles to the axis of this part, the fin having a transversely weakened zone dividing it into two parts, one adjacent, the other distant from the annular part, the distant part having a protruding shape, capable of coupling by snap-fastening with an orifice of the lever detent, the whole so that the first actuation of the detent lever separates the distant part as a result of the rupture of the fragile zone.

L'invention sera mieux comprise par la description détaillée qui suit, fournit à titre purement indicatif et faite en relation avec la figure 1 du dessin ci-joint qui montre une section longitudinale du dispositif de l'invention sur un pulvérisateur avec levier à détente partiellement reproduit en section longitudinale. The invention will be better understood from the detailed description which follows, provided purely by way of indication and made in relation to FIG. 1 of the attached drawing which shows a longitudinal section of the device of the invention on a sprayer with partially detent lever reproduced in longitudinal section.

En se référant à la figure, (1) indique un pulvérisateur présentant un corps (2), un levier à détente (3) monté sur charnière en (4), sur ce corps et relié en (5) à la tige (6) d'un piston (7) monté coulissant dans un cylindre (8) faisant partie du corps (1). Des ressorts en rappel (9) agissent sur le levier à détente pour le ramener avec le piston en position de repos. Le piston et le cylindre constituent la pompe, dont le tuyau de refoulement (10) prévu sur le corps (1) se termine par une buse (11). Referring to the figure, (1) indicates a sprayer having a body (2), a trigger lever (3) mounted on hinge at (4), on this body and connected at (5) to the rod (6) a piston (7) slidably mounted in a cylinder (8) forming part of the body (1). Return springs (9) act on the detent lever to bring it back with the piston in the rest position. The piston and the cylinder constitute the pump, the delivery pipe (10) of which is provided on the body (1) ends in a nozzle (11).

Ce qui a été décrit jusqu'à maintenant fait partie de l'art antérieur. What has been described so far is part of the prior art.

Par contre l'objet de l'invention est un dispositif de garantie pour les cas d'abus, comprenant une partie annulaire (12) qui est enfilée sur la buse (11) de laquelle part à angle droit par rapport à l'axe longitudinal de cette pièce, une ailette (13) présentant une zone affaiblie transversalement (14) la subdivisant en deux parties, l'une voisine, l'autre (15) proche de la partie annulaire (12), l'autre distante (16) présentant sur sa partie dorsale une saillie ou un bouton creux de forme (18), ayant une extrémité libre réduite à laquelle succède immédiatement un bord d'arrêt (19). Le bouton ou saillie (18) est inséré à encliquetage avec un orifice (20) du levier à détente (3), orifice positionné de façon à permettre une telle insertion lorsque le levier à détente (3) est dans une position de repos de la figure. Le bord (19) s'engage par son chanfrein d'entrée dans l'orifice (20) après l'avoir traversé, de sorte que son extraction exigerait un effort tel que l'ailette casserait le long de la zone fragile (14). On the other hand, the object of the invention is a guarantee device for cases of abuse, comprising an annular part (12) which is threaded on the nozzle (11) from which leaves at right angles to the longitudinal axis of this part, a fin (13) having a transversely weakened zone (14) dividing it into two parts, one adjacent, the other (15) close to the annular part (12), the other distant (16) having on its back part a protrusion or a hollow shaped button (18), having a reduced free end which is immediately followed by a stop edge (19). The button or projection (18) is inserted by snap-fastening with an orifice (20) of the trigger lever (3), orifice positioned so as to allow such insertion when the trigger lever (3) is in a rest position of the figure. The edge (19) engages by its chamfer of entry into the orifice (20) after having crossed it, so that its extraction would require an effort such that the fin would break along the fragile zone (14) .

Lors de la première action exercée sur le levier à détente (3), la partie distante (16) de l'ailette suit le mouvement du levier sur un parcours très bref pour se séparer ensuite de l'autre partie (15) par suite de la rupture le long de la zone fragile (14). La partie annulaire
(12)-avec la partie voisine (15) n'étant pas solidaire de la buse (11) se
détache et se sépare au moment de la rupture de la zone fragile.During the first action exerted on the detent lever (3), the distant part (16) of the fin follows the movement of the lever over a very short course to then separate from the other part (15) as a result of rupture along the fragile zone (14). The annular part
(12) -with the neighboring part (15) not being integral with the nozzle (11) is
detaches and separates when the fragile zone breaks.

Donc, on peut constater immédiatement un abus éventuel. So you can immediately see a possible abuse.

Il est évident qu'au moins l'ensemble formé par la partie
annulaire de l'ailette avec le bouton correspondant sera réalisé en
matière plastique. It is obvious that at least the whole formed by the part
fin ring with the corresponding button will be made in
plastic material.
