CLAIMS

1. An automatic system (1 ) for closing windows or doors, comprising: a counter-plate (2) installable on a fixed frame and provided with a first member (3);

a lock body (20) installable on a door or window leaf and having a front portion (20b) intended to face said counter-plate (2) when the door or window leaf is aligned with the fixed frame, wherein said lock body (20) is provided with closing means (4) movable between a release configuration, wherein the closing means (4) engages the counter-plate (2) when the counter-plate (2) is aligned with the lock body (20), and a retained configuration, wherein the closing means (4) is maintained inside the lock body (20) and does not engage the counter-plate (2);

- a switch (5) mounted in the lock body (20), said switch (5) being configured to assume a locking configuration wherein the switch (5) locks the closing means (4) in the retained configuration (4) and a unlocking configuration wherein the switch unlocks the closing means (4), thereby activating the automatic movement of the closing means (4) from the retained configuration to the release configuration;

characterised in that

said switch (5) and said first member (3) are configured to exchange an activation magnetic-type action adapted to switch said switch (5) from the locking configuration to the unlocking configuration only in a final approaching step of said lock body (20) with respect to said counter-plate (2), which is a part of a closing step starting from when the lock body is partially facing the counter-plate and ending when the lock body is completely facing the counter-plate,

said switch (5) having a first leaf-side magnetic pole (14a) active at the front portion (20b) of the lock body (20) and said first member (3) having a frame-side magnetic pole (3a) active at a front portion (2c) of said counter plate (2), wherein said first leaf-side magnetic pole (14a) is active only on an opening side (L1 ) so as to magnetically interact with said first frame- side magnetic pole (3a) only in said final approaching step and exchange said activation magnetic-type action.

2. The automatic system (1 ) for closing windows or doors according to claim 1 , wherein said switch (5) and said first member (3) are configured to exchange a stabilization magnetic-type action adapted to maintain said switch (5) in the locking configuration at least in an initial approaching step of said lock body (20) with respect to said counter-plate (2) which is a part of the closing step starting from when the lock body starts to face the counter-plate and ending when the lock body is partially facing the counter-plate.

3. The automatic system (1 ) for closing windows or doors according to claim 2, wherein said activation magnetic-type action and said stabilization magnetic-type action are opposite, preferably said activation magnetic-type action being an attractive action and said stabilization magnetic-type action being a repulsive action.

4. The automatic system (1 ) for closing windows or doors according to claim 2 or 3, wherein said switch (5) has a second leaf-side magnetic pole (14b) having opposite polarity to the polarity of said first leaf-side magnetic pole (14a), said second leaf-side magnetic pole (14b) being active at the front portion (20b) of the lock body (20) and only on a closing side (L2).

5. The automatic system (1 ) for closing windows or doors according to claim 4, wherein the first frame-side magnetic pole (3a) extends so as to magnetically interact with said leaf-side magnetic pole (14b) at least in said initial approaching step, exchanging said stabilization magnetic-type action, and so as to magnetically interact with said first leaf-side magnetic pole (14a) only in said final approaching step, exchanging said activation magnetic-type action.

6. The automatic system (1 ) for closing windows or doors according to claim 4 or 5, wherein said switch (5) is adjustable to reverse the position of the first leaf-side magnetic pole (14a) and the second leaf-side magnetic pole (14b) onto the plane of the front portion (20b) of the lock body (20).

7. The automatic system (1 ) for closing windows or doors according to one or more of the preceding claims, wherein said switch (5) is movable between a locking position, corresponding to the locking configuration, and an unlocking position, corresponding to the unlocking configuration, and is preferably defined by a locking pin (10) axially slidable between said locking position and said unlocking position.

8. The automatic system (1 ) for closing windows or doors according to claim 7, wherein said locking pin (10), preferably made of a non-magnetic material, comprises a permanent magnet (12) arranged along the longitudinal axis (X) and having opposite poles active on opposite sides of the same longitudinal axis and two ferromagnetic elements (13a, 13b) adjacent to the permanent magnet (12) arranged respectively on a closing side (L2) and on an opening side (L1 ) and respectively defining a first leaf-side magnetic pole (14a) and a second leaf-side magnetic pole (14b) as an effect of the interaction with said permanent magnet (12).

9. The automatic system (1 ) for closing windows or doors according to claim 8, wherein said locking pin (10) is rotatable about the longitudinal axis (X) to reverse the position of the first leaf-side magnetic pole (14a) and the second leaf-side magnetic pole (14b) on the plane of the front portion (20b) of the lock body (20).

10. The automatic system (1 ) for closing windows or doors according to one or more of the preceding claims, wherein said first member (3) is

movable with respect to the counter-plate (2), and wherein a second member (6), distinct and separate from said switch (5), is integrally fixed to the lock body (20) in such a way that, when the leaf is aligned with the fixed frame, said second member (6) exercises an attraction force of a magnetic type on the first member (3) which approaches said first member (3) to the lock body (20) in such a way that it magnetically interacts with the switch (5) to activate the automatic switching of the closing means (4) from the retained configuration to the release configuration.

11. The automatic system (1 ) for closing windows or doors according to claim 10, wherein the first member (3) is movable, preferably slidably or rotatably, between a retracted configuration wherein the first member (3) is retracted inside a housing (2b) of the counter-plate (2) and an extracted configuration wherein the first member (3) is extracted from said housing (2b), to approach the switch (5), and wherein when it is in the extracted configuration, the first member (3) is in a resting condition, even indirectly, against an edge surface forming part of the lock body (20), at the switch (5).

12. A door or window, characterised in that it comprises an automatic closing system (1 ) according to any one of the preceding claims.
