Ventilation grill

Abstract

This utility model discloses a ventilation grill that consists of a face cover ( 1 )—a ventilation grill, with inclined fins ( 1 a ), forming a grill, with deviation in the “parallel to flange” position, of a rectangular housing ( 2 ) with a flange ( 2 a ) and a preventer ( 6 ), of an air flow control mechanism (FIG. 2 ) that includes a louver control wheel ( 3 ) that is connected via gear transmission with the louver control mechanism ( 4 ) that synchronizes the movement of the louvers ( 5 ), and has a louver control (and thus an air flow control) mechanism differing from a lever, and has a preventer against misalignment in the installation process, a simple design in production, and better functional properties in ranges of ventilation grills for suction or suction-and-exhaust ventilation with an air flow control mechanism.

1 . A ventilation grill comprising:
 a face cover ( 1 ) made as a ventilation grill, the ventilation grill face cover ( 1 ) comprising inclined fins ( 1   a ) bent to a parallel to flange position;   a rectangular housing ( 2 ) with a flange ( 2   a ) and a preventer ( 6 ) in the rectangular housing ( 2 ), and a mechanism for controlling an air flow, the air flow control mechanism comprising a louver control wheel ( 3 ) connected via a gear transmission with the louver control mechanism ( 4 ) that synchronizes the movement of louvers ( 5 ).
