Door or window of double action, characterized in that the edge of the fence, and therefore that of the frame of the moving leaf, have, within the plane of the first, an inclination, with respect to the vertical and towards the center of the door, both the smaller the weight of the moving leaf, the same being the inclination of the line determined by the axes of the hinges, so that when the moving leaf is placed at an angle less than 90º, with respect to the plane of the fence, it tends to close by its own weight; and if, on the contrary, that angle is greater than 90º, on its own it opens completely until resting against the wall in which the fence is mounted.
