Parallel control damper with support

Abstract

A damper support mechanism to reinforce a plurality of damper blades which are actuated together. When the blades are in a closed position, actuating brackets attached to each damper blade and a vertical bar are used to support the blades and preventing them from bending or breaking. The vertical bar is fixedly held in a stop mechanism located at the top or bottom of the vent opening.

1 . A support mechanism for at least one damper blade in a vent opening comprising:
 a first section attached to the damper blade;   a second section pivotally attached to said first section;   a third section pivotally attached to said second section; and   a vertical bar fixed to the third section;   the vertical bar being held in place via at least one stop mechanism attached to a top or bottom of the vent opening.   
     
     
         2 . The support mechanism of  claim 1 , wherein a plurality of damper blades are present, each having the support mechanism attached thereto and to the vertical bar via a third section, wherein the plurality of damper blades are reinforced by the vertical bar being held by the at least one support mechanism. 
     
     
         3 . The support mechanism of  claim 1 , wherein there are two stop mechanisms for the vertical bar, a first stop mechanism attached to the top of the vent opening and a second stop mechanism attached to the bottom of the vent opening. 
     
     
         4 . The support mechanism of  claim 1 , wherein the first section is attached to a rear of the at least one damper blade by a T-shaped or L-shaped bracket bar.
