Abstract

In a device for aerating and, if necessary, deaerating a space by means of individual nozzles arranged in a casing box (4, 4a), at least one individual nozzle (14) is rigidly mounted in a nozzle grid (5, 5a) arranged so as to swivel about an axis of the casing box (4, 4a).

Claims

1. A device for selectively supplying and exhausting air from a room comprising:

a frame for mounting the device in said room, said frame including a casing box;

at least one nozzle grille pivotably mounted within said casing box;

a plurality of nozzles within said at least one nozzle grille and fixed thereto for unitary movement therewith; and

means for selectively pivoting said at least one nozzle grille within said casing box for pivoting said plurality of nozzles in unison therewith.

2. The device as claimed in claim 1, wherein said nozzle grille includes a frame member pivotably mounted to said casing box wherein said frame member has an exterior contour which conforms with an interior contour of said casing box.

3. The device as claimed in claim 2, wherein said nozzle grille further includes at least one plate means secured to said frame member and defining at least one nozzle opening.

4. The device as claimed in claim 3, wherein one of said plurality of nozzle is fixed to said at least one plate means and is associated with one of said at least one nozzle opening.

5. The device as claimed in claim 2, wherein said frame member is pivotably mounted by bracket means to said casing box.

6. The device as claimed in claim 1, wherein a plurality of nozzle grilles are pivotably mounted within said casing box.
