Abstract:
A push-bar unit for doors in general, comprising: a bar element extending between first and second ends thereof along a plane which is adapted to be perpendicular to a surface plane of the door; couplings provided at the ends of said bar element for connection to the door; a threaded bar, comprising first and second ends thereof and being arranged inside said bar element; a lever having a first and a second pivoting ends; a pusher; a pawl for turning open by engagement a lock pivot of said door; and a free space being delimited by way of said couplings between said bar element and a surface plane of said couplings which is adapted to be connected to said door to which said bar element is connected, said lever being pivoted with the first pivoting end thereof to the bar element and with the second pivoting end to the pusher, said pawl being operatively connected with said pusher, whereby upon rotation of the pusher by action of said lever actuated following pressure applied to said bar element, the pawl rotates for turning open the door lock pivot, wherein said lever is constituted by two mutually parallel plates; a shoulder being rigidly coupled to each of said ends of said bar element, said parallel plates being pivoted to said shoulder; fixing elements being connected to each of said plates, at least a first one of said fixing elements allowing insertion and locking of a first one of the ends of said threaded bar.
