An eddy-current magnetic damper (80) for damping a door is used to brake two carriages (26) as follows: the two brackets are slidably mounted on linear guides (20) for slidably supporting the door.)

1. A servomechanism for moving a door of an article of furniture (MC), comprising:

-two parallel and horizontal linear guides (20),

two carriages (26) mounted in a sliding manner, for example via rollers, on the linear guides (20) respectively, for supporting the leaves in a sliding manner,

-an articulated parallelogram mechanism formed by a vertical bar (40) and two identical arms (50), said vertical bar (40) being connected to said two carriages and being mounted for supporting and moving said door, the two arms (50) being pivoted to the side panels of the article of furniture,

-a cam (54) integral with the arm,

-a movable slider (56) biased by a resilient element towards the cam so as to push on the cam and rotate the arm,

-a vortex magnetic damper (80) to damp the door.

2. Servomechanism according to claim 1, in which the magnetic damper comprises a linear guide in which a slide (80) integral with the leaf is mounted in sliding manner, the linear guide and/or the slide comprising a permanent magnet (88), and correspondingly the slide and/or the linear guide comprising a metal track (70) on which the magnetic field generated by the permanent magnet can impact and on which the permanent magnet can slide.

3. The servomechanism according to claim 1, wherein the metal track is made of a material selected from aluminium, copper or high carbon steel.

4. A servomechanism according to any preceding claim, in which the linear guide is integrated in one of two parallel linear guides.

5. Servomechanism according to any of the previous claims, wherein the linear guide and the one of the two parallel linear guides are constituted by a single profile (68), for example made of aluminium, copper or high carbon steel.

6. Servomechanism according to any of the previous claims, wherein the single profile (68) comprises a channel for a roller comprised in one of the carriages.

7. Servomechanism according to claim 5 or 6, in which the single profile or track comprises or consists of two cantilevered coplanar fins, sliders contained in the damper being mounted in sliding manner on opposite flat sides of said fins and comprising permanent magnets.

8. Servomechanism according to any one of claims 2 to 7, in which the slider comprises two flat and parallel elements (82) spaced apart, mounted so that they can slide while maintaining the coplanar fins between them, there being a permanent magnet (88) on each flat element.

9. The servomechanism according to claim 8, wherein the two flat and parallel elements each comprise a mild steel plate on which permanent magnets are arranged.

10. A servomechanism according to any preceding claim, in which each planar element comprises a row of permanent magnets aligned along the length of the track or a or each fin, the two rows of permanent magnets are parallel and arranged on opposite sides of the track or on opposite sides of the fins respectively, wherein all permanent magnets in a row or all permanent magnets in each row have N-S pole axes that are parallel to each other, and the N-S polar axis of each permanent magnet belonging to a row of permanent magnets placed along one side of the track or the fin coincides with the N-S polar axis of the permanent magnet of a row of permanent magnets placed on the opposite side of the track or the fin, and the permanent magnets in one or each row are oriented with their N-S pole axes having alternating directions.
