Abstract:
The present invention relates to a rotary drive (100) comprising: an output shaft (330); a motor (20), acting on the output shaft (330) via a downstream gear mechanism (30); an energy-store module with a linear line of action and with transmission elements (32, 326) to apply pressure circumferentially to an eccentric cam disk (331) arranged on the output shaft (330) for conjoint rotation therewith; and an intermediate shaft (320), being offset in relation said line of action and being provided between the motor (20) and the output shaft (330). The transmission elements (32, 326) comprise a roller lever (32), having a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disk (331), interacts with the output shaft (330). The energy-store module is arranged on the motor side in relation to the intermediate shaft (320).
Abstract:
A door closer is provided to automatically pull a storm or screen door to a fully closed position without user action. The door closer includes a bracket housing with a cam switch movable along a track as the door opens and closes. The closer cylinder rod is engaged with the cam switch until the door is fully opened. The cam switch biases the closer cylinder and rod as the door approaches the closed position.

Abstract:
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 spring (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:
A cantilevered folding gate (1) may be used with a module (13) which is suitable for fitting in such cantilevered folding gates (1) and includes a transmission mechanism (5) which is accommodated in a housing (14) and which is designed to transmit the movement of a first gate leaf (3) to a second leaf (4) so that the first (3) and second (4) gate leaf open or close simultaneously by folding.
Abstract:
A door closer is described, which has an output shaft, on which a cam disc is torsion-resistantly disposed, and has a pressure roller. By means of an operational connection, a closer spring presses the pressure roller against a running surface of the cam disc. In relation to an axial center of the output shaft, the pressure roller is disposed such that, during opening or closing of a swing leaf coupled to the output shaft, the pressure roller is movable along a path. Due to the fact that the path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, at a respective opening angle of the swing leaf, in different modes of operation of the door closer, a very similar or identical torque is respectively applied to the output shaft.
Abstract:
A hinge for a closing door of a compartment, of the type having a first and a second body, respectively integral to the door and to the frame of the corresponding compartment, or vice versa, and mutually hinged by at least one pin, first elastic means mounted on the second body and acting upon the first body, and at least one dampening device fixed to the second body, acting upon the first body and actuated by at least a first slider, functionally connected to the dampener, and by at least a second slider, configured for engaging, directly or indirectly, the aforesaid first body in correspondence of at least a certain angular range assumed by the first body with respect to the second body during their relative rotation, whereby the second slider is actuated in translation by the first body when engaged therewith, as well as constraining means between the first slider and the second slider. Advantagiously, the aforesaid constraining means include at least a lever pivoted to the second body, and the aforesaid first and second slider are constrained at least in rotation to one lever.
Abstract:
An output shaft, to which the rotational force of a motor is transmitted, is rotatably supported and housed in a case. One end of the output shaft protrudes from the case, and a pinion gear is provided on this one end. Teeth that mesh with the pinion gear are provided on the outer circumferential surface of cables. A guide member for guiding the cables in such a way that they mesh with the pinion gear is mounted on the case. An urging plate portion that presses against the side of the pinion gear is provided on the guide member. The urging plate portion urges the output shaft in the axial direction and, as a result, rattle of the output shaft is alleviated.
Abstract:
The present invention relates to an actuator (1), comprising an output member (6); a resilient element (8) connected to said output member (6) so as to urge it in a first direction; and an hydraulic rotation damper (5) with a closed cylinder cavity, a rotational damper shaft which extends into the cylinder cavity, and a piston dividing the cylinder cavity into a first side and a second side. Within the rotation damper (5), the rotational movement of the damper shaft is converted into a translational movement of the piston along a longitudinal axis of the shaft. A restricted fluid passage communicates said first and second sides. The damper shaft is connected over a gearing (10, 15, 17) to the output member (6) and resilient element (8) of the actuator for damping movement of said output member (6) in said first direction.The present invention relates to both rotational and linear actuators as well as to a closing mechanisms for hinged members, such as doors, gates, or windows, comprising such actuators.
Abstract:
The hinge for wings or doors, in particular of electrical appliances, comprises a first box-shaped body, a second box-shaped body, a connecting element between the first and second bodies, and a damper cylinder for applying on the second body an action damping its movement towards the first body.
