Airchaser

Abstract

Extremely lightweight device which hangs from the ceiling by 1 point (2 screws), used for absorbing/pulling in air, smoke and vapors and gets it out to the ceiling duct or window.Made of 2 extensible sticks, having 1 point of support and 2 points of pushing on the ceiling. The hood (tip of the device) can be rotated/moved in the room 360 degrees, basically anywhere needed for the air extraction.

a) A vent hose which hangs by 2 extensible metal sticks on the ceiling, being attached on the ceiling by 1 point; 2 screws. The 2 metal sticks are attached one to another by 1 rotative point at the end of the first extensible stick. 
     
     
       b) The first stick counterbalances by one termination pushing on the ceiling(pushing up); and the ceiling attachment point (pulling down). The second stick counterbalances by the first stick's termination (pulling down); and pushing on the ceiling with one termination (pushing up). 
     
     
       c) At the termination of the second stick, the hose goes down attached to an acrylic tube. Inside the acrylic tube is another smaller tube sliding back and forth; which has an umbrella's canopy attached at the down-termination of the smaller tube. 
     
     
       d) The umbrella comes out of the acrylic tube hanging by rubber bands (attached on acrylic tube) which stops the inside smaller tube from coming out, smaller tube being connected with the top-center of the umbrella's canopy, allowing the umbrella to open freely and go back in the acrylic tube.
