The electric mechanism of opening overchanging windows with horizontal support consists of one electric motor (1.1) with extended arm (1.3), that is installed in the profile of the windowsill (1.2) in a parallel manner to its surface. The edge of the arm (1.4) is connected with a blade (1.5), that is installed within special notches of the profile of the windowsill and it is moved horizontally pushed by the arm. In every window there are two or more pairs of forks (1.6a 1.6b), from which the one side is larger and it is connected to the window (1.7a, 1.7b) and the other is smaller (1.8a, 1.8b) and it is connected to the larger side (1.9a, 1.9b) so that a relation of lever operation is created. From the two sides, the one is connected to the blade (1.10a, 1.10b) ad it is moved, while the other is connected to the windowsill (1.11a, 1.11b) and remains fixed. In this manner and by the alternation of support of the sides by the installation of the one fork inversely to the other, it is possible for the conversion of the parallel movement of the arm to the level of the window to become vertical, so that the window opens and closes. |
