Closing And Opening Devices For Wings, And Checks For Wings
(AREA)
Abstract
Articulation device for automatic closing doors, essentially characterized in that it is constituted by a substantially semicircular arm provided with two extreme expansions, one of them, depending on the radius of that semicircular arm, rotating on an axis that is disposed inside the profile of the frame, and the other, which is tangent in vertical to the aforementioned semicircular arm, destined to be fixed internally on the profile of a wing, and in that the axis of rotation of the first radial expansion also has a torsion spring wound solved to the same so that the opening of the leaf determines the displacement of the semicircular arm around the central axis of rotation and the automatic recovery of that leaf through the distortion that the spring coils to the axis itself.
