(57) A selvage (1) for secondary wing of fire doors which is fully reversible, of the
type which comprises a body provided with gears associated with respective vertically
sliding sliders (19), gears associated with an antipanic opening handle, which comprise
two contoured and superimposed plates (13) which can slide axially within the selvage
(1) and are contoured at one end so as to form a pusher (15), an angular spring (M)
which has one arm which rests on the rear wall (3) of the selvage (1) and another
arm engaged on an element which is rigidly coupled to the plates (13) in order to
keep their end faces rested respectively against the upper wall (4) and the lower
wall (5) of the selvage (1), two lever arms (12), which are rigidly coupled to the
bits (11) and rest against elements which are rigidly coupled to the plates (13).
The body is symmetrical with respect to a horizontal plane which passes through the
centerline and is provided with two symmetrical bits (11), each individually adapted
to engage the antipanic handle. The elements rigidly coupled to the plates (13) are
rockers (24), which are pivoted substantially at their centerline to the respective
plate (13) and in which the end that lies opposite to the contact end for the lever
arms (12) can be rigidly coupled selectively to the respective plate (13).
