## Abstract

A linear air diffuser for a suspended ceiling, which allows using a stretch ceiling material or any other suspended ceiling material or both simultaneously (installed on different sides of the profile) and also enables covering the point of connection of the mounting profile and stretch ceiling material or suspended ceiling material. The linear air diffuser also functions as a partition in a stretch ceiling.

## Claims

### Claim 1

A linear air diffuser for a suspended ceiling for use indoors, the linear air diffuser comprising:
a ventilation unit comprising an insulated double chamber plenum box, a ventilation opening, and an air flow regulator,
the linear air diffuser further comprises a mounting profile mounted to an air outlet part of the ventilation unit, and an air diffuser profile mounted to the mounting profile, and
the air diffuser profile consisting of two lateral sides with slits, wherein the two lateral sides are connected at an acute angle and a drop-shaped air deflector connected at a top of the two lateral sides, wherein:
the mounting profile is formed of an H-profile having a perforated horizontal connection surface, and an upper and a lower part, and a downwards duct for attaching a stretch ceiling material is located at bottom of external sides of the lower part;
on an outer side of the downwards duct is a mounting bracket at a right angle, where an external wall of a vertical part of the mounting bracket has vertical grooves and the mounting bracket is intended for attaching a suspended ceiling element;
at a lower end of inner sides of the lower part of the mounting profile is a groove which opens downwards for attaching the air deflector profile;
each of the two lateral sides of the air deflector profile has at a middle a vertical protrusion with a widened end for mounting the air deflection profile to the groove of the mounting profile and a bottom edge of each lateral side of the air diffuser profile projects horizontally for additional support for the suspended ceiling element and for covering a connection point of the stretch ceiling material and the suspended ceiling element.

### Claim 2 (depends on 1)

The linear air diffuser for the suspended ceiling according to claim 1, wherein the suspended ceiling element is of gypsum board.

### Claim 3 (depends on 1)

The linear air diffuser for the suspended ceiling according to claim 1, wherein the suspended ceiling element is of boarding material.

### Claim 4 (depends on 1)

The linear air diffuser for the suspended ceiling according to claim 1, wherein the suspended ceiling element is of metal strips.

### Claim 5 (depends on 1)

The linear air diffuser for the suspended ceiling according to claim 1, wherein the linear air diffuser is a partition in a stretch ceiling by crossing through the suspended ceiling.
