Abstract

Forma oggetto della presente invenzione un bocchettone (1) del tipo associabile a maschere protettive (2) comprendente un corpo principale (4) presentante una apertura di inspirazione (5) ed una apertura di espirazione (6) reciprocamente affiancate.Sull'apertura di inspirazione (5), predisposta ad impegnare un elemento filtrante (8a) o un condotto di alimentazione d'aria (8b, 8c), è ricavato un innesto a baionetta (13) predisposto ad effettuare l'impegno amovibile del corpo principale (4) in corrispondenza di un primo foro (11) ricavato su una porzione di ancoraggio (10) destinata ad essere solidale alla maschera (2).Una bussola filettata di fissaggio (17), incorporante eventualmente una valvola unidirezionale (20), viene impegnata nell'apertura di espirazione (6) dall'interno della maschera (2), attraverso un secondo foro (12) della porzione di ancoraggio (10), per fissare il corpo principale (4).The subject of the present invention is a union (1) of the type that can be associated with protective masks (2) comprising a main body (4) having an inspiration opening (5) and an exhalation opening (6) mutually placed side by side. (5), arranged to engage a filter element (8a) or an air supply duct (8b, 8c), a bayonet coupling (13) is made, arranged to carry out the removable engagement of the main body (4) in correspondence of a first hole (11) obtained on an anchoring portion (10) destined to be integral with the mask (2). A threaded fixing bush (17), possibly incorporating a one-way valve (20), is engaged in the opening exhalation (6) from inside the mask (2), through a second hole (12) of the anchoring portion (10), to fix the main body (4).
