Novel Solution for the Mechanism Used in the Actuation of Intelligent Roof Windows

The window roofs are available in the variants top-hung and center pivot roof window with actuation based on rack or chain mechanisms. The new solution proposed for center pivot roof windows is based on a geared linkage. Its scheme is explained and its analysis is performed in order to get functional parameters. The CAD model was generated and used to simulate the kinematic behavior, then a prototype was assembled to test the practical functioning. The mechanical system is actuated by an intelligent control system, which includes an Arduino board and sensors for light, temperature, pressure and humidity.
