Abstract:
A device for anchoring to a shutter (11) the free end (12) of a flexible element (13) associated with an actuator (15) for moving the shutter (11), the device (10) comprising an engagement terminal (16), which is rigidly fixed to the free end (12) of a partially flexible chain (14), and a complementary engagement block (17), which can be coupled to the engagement terminal (16) and is rigidly fixed to the shutter (11). The anchoring device (10) allows fine adjustment of the distance of the engagement terminal (16) from the chain, so as to adjust in an optimum manner the closure of the shutter (11) on the casing (11a). The engagement block (17), by way of mutually opposite elastically deformable wings (33), allows quick and easy engagement and release of the engagement terminal (16) according to requirements. The anchoring device (10) allows to avoid the sudden collapse of the chain (14) and the consequent uncontrolled closing of the shutter (11).
Abstract:
A box-like container for electric actuators for moving shutters by means of a chain, comprising two shell portions (11, 12) made of plastics, which are mutually coupled so as to form the outer enclosure (13) of the box-like container (10), and a third shell portion (17) made of plastics, which is arranged inside the outer enclosure (13) and is coupled to the inner bottom (18) of one of the two shell portions (11, 12) so as to delimit a first receptacle, in which the movement chain (15) is provided, and a second receptacle (20), which contains the electric and electronic components (25, 28) and part (16) of the gear systems for actuating the chain (15), the third shell portion (17) having an overmolded gasket (22) on the edges (21) for coupling to the inner bottom (18) of one of the two shell portions (11, 12).

Abstract:
A rotor (10) for a permanent-magnet linear actuator (11), comprising a series of permanent magnets (12, 12a, 12b, 12c, 12d) which are supported by a shaft (13) associated with means for its rotation (14, 15), the permanent magnets being arranged laterally adjacent in the direction of the longitudinal axis (X) of the shaft, with polarities that are shifted out of phase, in succession, by a preset angle. Each permanent magnet (12, 12a, 12b, 12c, 12d) is constituted by a flat body which comprises a central portion (16) for fixing to the shaft (13) and at least two opposite symmetrical pole shoes (17, 18) which form the poles, with an external profile (19, 20) shaped like a circular arc.
Abstract:
A linear actuator (10) particularly for sliding doors and for sliding door or window closure elements in general, comprising a box-like body (11), to be fixed with corresponding means of fixing between the two jambs (S 1, S2) of a door (P) or of a window or door frame, in order to move a leaf (A) by translational motion, fixed drive means being accommodated within the box-like body (11) which are adapted to move corresponding transmission means which are associated with the leaf (A). The box-like body (11) is telescopic in structure in order to be adapted in length to the width of the space of the door (P), or other window or door frame, with which it is intended to be used.
Abstract:
A device for adjusting the trim of a linear actuator for automating doors or windows, to be associated with the body (12) of a linear actuator (11). The device (10) comprises a pair of guides (15) provided with a series of grip protrusions; the guides are arranged on opposite sides of the body (12) of the actuator (11); a jaw (18) of a clamp (19) is engaged, by means of a corresponding complementarily shaped fastening and grip surface (17) thereof, on each of the guides (15) so as to perform a translational motion, the clamp (19) being in turn designed to be coupled rotatably to a bracket (20) for fixing to the casing or to the leaf of a door or window.
Abstract:
An actuation assembly for moving casements, of the type which comprises an outer enclosure (11, 111, 211, 311) for containing the electromechanical components for actuation (13) and the electronic components for management and control (16), comprising rain detection sensor means (24, 124, 224, 324) which are integrated on a position (25, 125, 225, 325) of the outer enclosure (11, 111, 211, 311) and are connected directly to the electronic components (16), adapted to actuate the closing movement of an associated casement (S) if the detection is positive.
