Abstract:
A piston device for the controlled rotatable movement of a closing element (D) anchored to a stationary support structure (W) including a tubular body (10) removably insertable into at least one seat (S) of a hinge device (H), an actuating head (20) external to the tubular body (10), a plunger member (30) slidably movable unitary with the actuating head (20) between a retracted end position and an extended end position, elastic contrast means (50) acting on said plunger member (30) for the returning thereof from the retracted end position to the extended end position and a working fluid acting on the plunger member (30) to hydraulically counteract the action thereof. A hinge device in which the piston device is removably insertable.
Abstract:
A control mechanism provides a clutch module for selective locking and unlocking of a drive shaft used to retract and extend the shade element between storage and extended positions. The clutch module includes a reciprocator element that engages a key extending from an outer surrounding housing. A locking member between the reciprocator element and a coupling element carried by the drive shaft selectively locks and unlocks rotational coupling between the reciprocator element and the coupling element, thus selectively locking and unlocking the drive shaft. A cushioning mechanism, a unidirectional dampening or frictional deceleration is provided for the drive shaft. The cushioning mechanism includes an impeller or rotor immersed in a cushion medium that impedes rotation of the rotor, and hence the drive shaft to which the rotor is coupled.
Abstract:
It refers to a door closing device (10) for an automatic closing of a door leaf (B) coupled with a floor and/or a doorpost (S) so as to swing. The door closing device (10) comprises a fixed unit (12) that is fixed on the floor and/or the doorpost (S), a translating unit (14) and a rotating unit (16) on which the door leaf (B) is fixed. The coupling of the three units (12, 14, 16) and the presence of elastic means (38) are such that, when the rotating unit (16) rotates in a first sense of rotation, the translating unit (14) is caused to translate in a direction and such that, when the translating unit (14) translates in an opposite direction, the rotating unit (16) is caused to rotate in an opposite sense of rotation.

Abstract:
The invention relates to a method for controlling an adjustable drive element of an adjusting device, wherein the drive element (5) drives an output element (4) by means of an intermediate part (3), the drive element (5), the intermediate part (3), and the output element (4) each are pivotally supported about a rotary axis (M), and wherein a drive side torque introduced by the drive element (5) is transmitted to the output element (4) by the intermediate part (3), while an output side torque introduced by the output element (4) is blocked by the intermediate part (3), having the following steps: Pivoting the drive element (5) in a first (S1; S2) of two potential and opposite adjusting directions (S1, S2) about the rotary axis (M) thereof, so that the drive element (5) acts in the first adjusting direction (S1; S2) on a section (31; 32) of the intermediate part (3) and a torque introduced into the intermediate part (3) by the drive element (5) via the segment (31; 32) of the intermediate part (3) is transmitted to the output element (4) to be driven, and stopping the drive element (5) when the output element (4) has reached an intended position (P2). According to the invention, the drive element (5) is pivoted into a neutral position in the second adjusting direction (S1; S2) opposite the first adjusting direction (S1; S2) by a prescribed distance (a) by the section (31; 32) of the intermediate part (3) by means of which the drive element (5) previously acted on the intermediate part (3), after the drive element (4) has reached the intended position (P2) thereof. The invention further relates to an adjusting device coupled to a controller implementing such a control method.
