CLAIMS

1 . A device for controlling (1) the slats (2) of a blind with adjustable slats (2) that comprises a rotating longitudinal support body (7) of rockers (6) connected by rods (4, 5) opposite each other for the synchronisation of the oscillation thereof, characterised in that said rods (4, 5) are flexible and in that the longitudinal support body (7) is longitudinally divided into a plurality of modules (8) along which the rods (4, 5) extend longitudinally.

2. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to the preceding claim, characterised in that each module (8) rotational ly supports a corresponding rocker (6).

3. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to any one of the preceding claims, characterised in that said modules (8) are serially connected by means of articulated connection means suitable for permitting winding of the support body (7) as a consequence of an elastic flexion of the rods (4, 5).

4. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to the preceding claim, characterised in that said articulated connection means comprises at least one elastic tab (30) that is lockable in a seat (26) by means of a snap-fit coupling tooth (27).

5. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to any one of the preceding claims, characterised in that the rocker (6) has a rotating driving pin (9) of a bushing (10) that is solidly constrained to a cap (1 1 ) for a slat (2), said bushing (10) being, in turn, engaged in a rotating seat (12) passing through the thickness of a base wall (13) of the module (8).

6. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to the preceding claim, characterised in that the lateral coupling surfaces between the bushing (10) and the driving pin (9) have conjugated formations (16, 17) for a friction rotating coupling between said bushing (10) and said driving pin (9).

7. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to any one of the preceding claims, characterised in that said rods (4, 5) are configured as laminae.

8. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to the preceding claim, characterised in that said rods (4, 5) have longitudinal tracts (40) of structural sti ffening with a substantially non-flat cross section.

9. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to claim 7 or 8, characterised in that said rods (4, 5) have longitudinal tracts (41 ) with a substantially flat cross section so as to facilitate flexion.

10. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to any one of claims 7 to 9, characterised in that said rods (4, 5) have engagement holes for pins (23, 24) for coupling with said rockers (6), said holes being made without removal of material in such a manner as to define collars for reinforcement of the wall thickness of the rods (4, 5).

1 1. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to any one of claims 5 to 10, characterised in that said bushing (10) has external ribbing ( 19) suitable for reducing the contact surface with the said rotation seat ( 12) thereof.

12. The device for controlling (1 ) the slats (2) of a blind with adjustable slats (2) according to any one of claims 5 to 1 1 , characterised in that said driving pin (9) has an axial cavity (25), wherein a burglar-resistant system plug can be positioned.

13. The device for controlling (1) the slats (2) of a blind with adjustable slats (2) according to any one of the preceding claims, characterised in that said module (8) has at least one elastic element (3 1) of compensation for the differential thermal expansion to which it may be subjected with respect to the rods (4, 5).

14. A blind (3) with adjustable slats (2) characterised in that it comprises a device for controlling (1) the slats (2) in accordance with any one of the preceding claims.
