(57) A device for stabilising the closure of wings (1,2) of folding doors (8) comprising
a rectilinear rod (34), attached to the top crosspiece (6) of the closing wing (1),
able to guide a slider (35), elastically constrained to the rod (34) by elastic means
(33), in such a way that, with the wings coplanar, a torque (M) is created around
the axis of rotation (r) of the articuled joint (4) coupling the wings (1,2) sufficient
to maintain the wings(1,2) perfectly coplanar by the restraining reaction deriving
from the action of the second end of the slider (35) on the upright (7) of the jamb
or on a limit stop (10) of a groove (11) guiding a pin (9), borne by said second end
of the slider (35), to guide the wings (1,2) as they slide.
