Device for closing and/or opening of a leaf

Device (1) for closing and/or opening of a leaf, to be applied to a concealed hinge (100), the hinge (100) comprising two bodies (101, 101′) articulated to each other through at least a pair of articulation arms (102, 102′) and connectable respectively to a leaf and to a fixed structure, said device (1) configured to be associated with one (101) of said two bodies of said hinge (100), said device (1) comprising:

• a translating element (2) engageable to/with an articulation arm (102) of said hinge (100),
• at least one mobile group (3) configured to cooperate with said translating element (2) and which is mobile with respect to an element/structure (11) which can be mechanically fixed to a hinge body (101) to which said device is intended to be associated;
• elastic means (4) acting on said mobile group (3) to cause the movement of said mobile group (3) and said translating element (2);
• wherein said translating element (2), said at least one mobile group (3) and said elastic means (4) are configured and reciprocally arranged so that a closing or opening rotation of a door associated with said hinge (100) comprises:
• a first phase in which a closing or opening rotation of said leaf is activated and caused only by a force/action external to said device, by an external force/action exerted by a user on the leaf,
• a second phase of said closing or opening rotation, subsequent to said first phase, in which said elastic means (4) act on said mobile group (3) to cause movement of said mobile group (3) and therefore of said translating element (2), thus causing an automatic closing or opening rotation of the door;
• and wherein the device (1) is configured such that, during said first phase, the device (1) comprises a condition A1 in which the translating element (2) does not cooperate with the mobile group (3) and/or cooperates with the mobile group (3) without causing movement of the mobile group (3), wherein said mobile group (3) comprises:
• at least one carriage (20) or slide which can rototranslate along a guide (18) which is integral with a containment body (11) which can be associated with the hinge body (101).

• elastic means (4) acting on said mobile group (3) to cause the movement of said mobile group (3) and said translating element (2);
• wherein said translating element (2), said at least one mobile group (3) and said elastic means (4) are configured and reciprocally arranged so that a closing or opening rotation of a door associated with said hinge (100) comprises:
• a first phase in which a closing or opening rotation of said leaf is activated and caused only by a force/action external to said device, by an external force/action exerted by a user on the leaf,

• wherein the device (1) is configured such that, during said first phase, the device (1) comprises a condition A1 in which the translating element (2) does not cooperate with the mobile group (3) and/or cooperates with the mobile group (3) without causing movement of the mobile group (3),
• wherein said mobile group (3) comprises at least one of:
• -at least one rotating element (5) which rotates around an axis of rotation X, which is mounted/constrained and integral with a containment body (11) which can be associated with the hinge body (101) and which is substantially transverse/perpendicular to the translation axis Y of said translating element (2), or
• at least one carriage (20) or slide which can rototranslate along a guide (18) which is integral with a containment body (11) which can be associated with the hinge body (101), wherein said mobile group (3) further comprises at least one further rotating element (50) which rotates around an axis of rotation X2, which is mounted/constrained and integral with a body of containment (11) associable with the hinge body (101) and which is substantially transverse/perpendicular with respect to the translation axis Y of said translating element (2), and is configured so that said translating element (2) and said rotating element (5) cooperate with each other by means of said at least one further rotating element (50).
