Abstract

L'invention concerne un dispositif pulvérisateur à gâchette conçu de façon que la gâchette et un piston ne puissent fonctionner qu'après un déblocage, d'où l'obtention d'une sécurité-enfants. Ce dispositif pulvérisateur à gâchette comprend une unité piston (52) disposée de manière à se déplacer en va-et-vient dans le cylindre (65) et supportée élastiquement par un ressort de rappel (51), l'extrémité avant de l'unité piston (52) étant associée à un côté arrière de la gâchette (80) et les côtés de l'unité piston (52) faisant saillie de manière à former des nervures de blocage, ainsi qu'un élément de blocage (53) monté pivotant dans une extrémité ouverte du cylindre (65) et comportant un trou traversant (53a) en forme d'anneau que l'extrémité avant de l'unité piston (52) peut traverser, des rainures de coulissement (53b) étant formées sur la circonférence intérieure du trou traversant (53a), ce qui permet un déplacement sélectif de ces nervures de blocage (52c). Ainsi, lorsque les rainures de coulissement (53b) et les nervures de blocage (52c) ne sont pas parallèles les unes aux autres, la gâchette (80) et l'unité piston (52) conservent leur état bloqué. Cela permet d'empêcher l'actionnement de la gâchette (80). Par conséquent, ce dispositif pulvérisateur à gâchette est doté d'une sécurité-enfants. En outre, étant donné que l'unité piston (52) est toujours reçue dans le trou traversant (53a), cette unité piston (52) n'est pas déformée même lorsque la gâchette est soumise à une pression à partir de ses deux côtés ou à un choc pendant le transport du pulvérisateur.
