Cierra-puertas perfeccionado que consiste en una caja esencialmente cilíndrica fija, en cuyo interior se aloja un conjunto móvil, giratorio accionado por un brazo articulado cuyo otro extremo está aplicado a la puerta, y que, en la acción de apertura de ésta gira en un sentido tal que comprime un resorte concéntrico interior de torsión, el cual una vez cesa la fuerza que mantiene la puerta abierta, provoca el retorno de ésta a su posición de cierre, a la que corresponde la posición normal del resorte cargado.
