Patent

CA 2209795

An air cleaner (10) includes a housing (12) having a first section (14) and a second section (16). The first and second sections (14) and (16) are rotationally adjustable relative to one another. Alignment teeth (42) and (60) engage one another to position the two sections (14) and (16) relative to one another. Buckle type clasps (60) engage a ridge (44) to cam together the sections (14) and (16) and lock them in sealed engagement. A mounting bracket (80) includes a somewhat flexible band (82) which extends around the housing (12). The band (82) includes raised block portions (88) extending radially inward and spaced about the inner surface of the band (82). The housing includes a locking portion (30) having recesses formed therein which are spaced and aligned to receive raised block portions (88) of the mounting band (82). When the bracket (80) is placed around the housing (12), the raised block portions (88) engage the recesses of the lock portion (30) and the bracket (80) is held in place. If rotational adjustment is needed between the bracket (80) and the housing (12), the band portion (82) is flexed outward so that the raised block portions may disengage. The band (82) is then unflexed to retain the bracket (80) in its new position.

L'invention porte sur un filtre à air (10) comportant un boîtier (12) comprenant une première section (14) et une deuxième section (16) ajustables en rotation l'une par rapport à l'autre. Des dents d'alignement (42 et 60) s'engagent les unes dans les autres pour positionner les deux parties (14, 16) l'une par rapport à l'autre. Des crochets à ressort (56) en agrippant le boudin (44) emboîtent les deux parties ensemble et les verrouillent de manière étanche. Une bride de montage (80) comporte un ruban relativement flexible (82) qui entoure le boîtier (12). Ledit ruban (82) comprend des plots (88) saillant radialement vers l'intérieur et répartis sur la surface interne du ruban (82). Le boîtier comporte un verrouillage (30) présentant des évidements (88) dont l'espacement et l'alignement correspond aux plots (88) du ruban de montage. Lorsque la bride (80) est placée autour du boîtier (12) les plots (88) s'emboîtent dans les évidements (88) de la portion de verrouillage (30) ce qui maintient la bride (80) en place. Si un ajustement en rotation entre la bride et le boîtier est désiré, le ruban (82) est défléchi vers l'extérieur pour permettre de dégager les plots. Le ruban est ensuite ramené vers l'intérieur pour maintenir la bride (80) dans sa nouvelle position.
