1. Damped and compact hinge device for doors, shutters and hatches of an apparatus or furnishing for closing and opening a respective door and comprising, in an operating condition of assembly to the apparatus,
a first member (3) fixed to a body of the apparatus and a second member (5) fixed to the door of the apparatus or made in the door, wherein the first member (3) and the second (5) member are mutually connected by a pivot pin (7) for the rotation of the door around a rotation geometric axis of said pivot pin (7) between extreme opening (A) and closing (C) conditions of the door; the device (1) further comprising
a friction shoe (9) sliding on a respective friction wall means (11) of the first member (3) and connected to the second member (5) by means of interconnection means (13) causing the sliding of the friction shoe (9) along the friction wall means (11) following the rotation of the second member (5) for opening and closing the door; the device further comprising
a linear resilient means (17) having a first end fixed to a connection (19) of the first member (3) and a second end connected to a first fixing pin (21) borne by a first end of a lever means (23) of the device for transmitting to the lever means (23) an elastic force away from the second member (5), wherein the lever means (23) is connected to the friction shoe (9) by means of a swiveling connection means (25); wherein
the connection (19) of the first member (3) for the corresponding end of the resilient means (17) is placed on a side of a geometrical plane defined by the friction wall means (11) opposite to that of the friction shoe (9) or is placed on a same side of the geometrical plane defined by the friction wall means (11) of the first fixing pin (21) and of the friction shoe (9) and a distance of said connection (19) from this plane is lower than a distance of the first fixing pin (21) from the geometric plane so as to incline the resilient means (17) with respect to the geometric plane and to transmit to the lever means (23) an elastic force with a direct component towards the geometrical plane by pressing the friction shoe (9) against the frictional wall means (11); wherein
a second end of the lever means (23), opposite to the first end bearing the first fixing pin (21), is provided with a first mobile pin (27) for sliding along first slot means (29) of the first member (3) or of an element fixed to the first member (3), the first slot means (29) oriented parallel or inclined with respect to the friction wall means (11); wherein
the interconnection means (13) comprise a rocker arm means (35) having a first end linked to the first mobile pin (27) and having an opposite end rotatably connected to the second member (5) by a third fixing pin (37) spaced from the pivot pin (7); wherein
a median portion of the rocker arm means (35) has a second mobile pin (41) for sliding in a second slot means (43) of the first member (3) or of an element fixed to the first member (3), the second slot means (43) having a rectilinear shape, a curved shape, or an S or C shape.
