Abstract:
A guide (10) for a permanent-magnet linear actuator (11), of the type comprising a row of permanent magnets (12, 12a, 12b, 12c) which are arranged side by side and substantially parallel and equidistant. The guide (10) is constituted by a series of modular elements (13, 14, 14a) which can be interconnected in the direction of extension of the guide with interlocking means for simplified fixing.
Abstract:
A box-like container for electrical actuators for automating doors or windows, containing internally an electric motor (14), the associated electronic components (15), at least part of a push-pull element (12) for moving the leaf of the door or window, and a gear train (16) for reduction and torque transmission. The box-like container is constituted by two shell portions, a first one (17) and a second one (18), which form the outer enclosure and have corresponding internal partitions (24), which when juxtaposed when the shell portions (17, 18) are closed onto each other, provide a first chamber (20) for the motor (14), the electronic components (15) and at least part of the gear train (16), and a second chamber (21) for at least part of the push-pull element (12), a gasket (23) being interposed between the two shell portions (17, 18) and being shaped so as to cover the facing perimetric edges (17a, 18a) of the two shell portions (17, 18) and the edges (24a) of the juxtaposed partitions (24) which divide the first chamber (20) from the second chamber (21).
Abstract:
A chain-drive actuator assembly, particularly for moving large doors or windows, comprising an outer enclosure (11) which is predominantly longitudinally elongated and inside which two similar single-chain actuators (12) are aligned at a preset distance, each actuator having the outer working end (14) of the respective chain preset so as to pass through an opening (16) provided in the outer enclosure (11). The single-chain actuators (12) are associated with means (33) for their simultaneous actuation. The outer enclosure (11) has a supporting and covering function for the two single-chain actuators (12).
Abstract:
An electric lock (10) for sliding doors or shutters, comprising an element (11) to be engaged which is adapted to protrude from an edge (12) of a sliding door or shutter (13) and is intended to be engaged and retained reversibly, in a stroke limit position for the door or shutter (13), by a reversible device (14) for automatic engagement and locking, which is fixed to the frame (15) of the sliding door or shutter (13).
Abstract:
A linear actuator (10), particularly for sliding doors and for sliding doors and windows in general, comprising a supporting body (11), to be fixed by corresponding fixing means between the two jambs (S1, S2) of a door (P) or of a door or window frame, motor drive means (12) being accommodated and fixed within the supporting body (11) and being adapted for the rotation of a driving gear (13), which is intended to mesh with a driven rack (14), which in turn is fixed to a leaf (A) of the door (P) to be moved in translation.
Abstract:
A permanent-magnet linear actuator (10), comprising a movable part (11), to be jointly connected to a first body adapted to be moved with respect to a second fixed body, and a fixed part (12), to be jointly connected to the second body designed to remain substantially stationary, a first one of the two parts (11, 12) comprising guiding means (13) for corresponding sliding means (14) that are jointly connected to the second part, one of the parts (11, 12) having a series of first permanent magnets (15) that are aligned in at least one row (16) that lies along the direction of translational motion defined by the cooperation of the sliding means (14) with the guiding means (13), the other one of the two parts (11, 12) having a rotor element ( 17) which faces the at least one row (16) of first permanent magnets (15) and comprises a series of second permanent magnets (18), which are supported by a shaft (19) associated with means (20) for its rotation, the second magnets (18) being arranged side by side in the direction of the axis of the shaft (19), with polarities that are offset by a preset angle.
