ABSTRACT:
A push-bar for doors in general, which comprises a bar element provided, at its ends, with couplings for connection to a door; the particularity of said push-bar is the fact that it is provided with a threaded bar which is arranged inside the bar element, each end of said bar element being connected to lever means which are in turn pivoted at one end to the bar element and, at the other end, to a pusher whose rotation as a consequence of a pressure applied to the bar element causes the rotation of a pawl which is adapted to engage the pivot of the lock of the door in order to turn it for opening, an empty space being provided between the bar element and the surface of the door to which the bar element is connected.
