In a hinge device 1, a door-side mounting member 6 is rotatably connected to a housing-side mounting member 3 via an inner link 4 and an outer link 5. To prevent the inner link 4 and the outer link 5 from being rattled, one protrusion 72 of a torsion coil spring 7 as a rotationally biasing mechanism is pressed against one side plate 41 of the inner link 4 via a cam member 91 and the other protrusion 73 of the torsion coil spring 7 is pressed against the other side plate 52 of the outer link 5.

A rotary damper includes a damper body having a cylindrical configuration and a rotor rotatably disposed in the damper body. The rotor is non-rotatably connected to an inner link so that the rotor is rotatable together with the inner link. Two teeth constituting a part of a gear are formed in an outer circumferential surface of the damper body. A tooth of a gear member rotatable together with an outer link is engaged with the teeth. By this arrangement, the damper body and the rotor can be rotated in opposite directions.

A rotary hinge assembly includes a hinge housing including at least one interior chamber. A spring disposed within the hinge housing provides a torque on an attached door while in an opened and closed position. A rotor rotatably disposed within the at least one interior chamber includes at least one rotor vane that moves in relation to a stationarily mounted stator having at least one stator vane. A fill plug includes a plurality of entrance and exit holes disposed in relation to the stator and rotor vanes to define a fluidic damper assembly. A valve disposed within the fill plug permits selective adjustment of the fluidic damper by restricting or opening the entrance and exit holes of the fill plug.

The present invention relates to an automatic door closer including: a main housing having the shape of a cylinder; a damper housing adapted to divide the interior of the main housing into an upper chamber and a lower chamber and having oil charged thereinto and a fixed vane formed at one side of the inner peripheral surface thereof in such a manner as to be projected toward the center thereof; a cover fixedly coupled to the upper periphery of the main housing; an activating shaft having one end extended to the outside through the cover in such a manner as to be rotatably supported and the other end rotatably supported against the bottom surface of the main housing through the damper housing; a rotary vane formed integrally to the outer periphery of the activating shaft so as to divide the interior of the damper housing into first and second chambers, together with the fixed vane; a return spring adapted to provide a returning force of returning the activating shaft to an initial setting position at the time when the door is closed; and damping means adapted to selectively provide a damping function if the activating shaft and the rotary vane are rotated in a closing direction of the door.

An identical engagement hole 12b is formed in each of first and second brackets 1, 2. A first engagement portion 31c is formed in a damper body 31 of a rotary damper 3. A distal end portion of a rotor 32 of the rotary damper 3 is non-rotatably inserted in an adapter 4. A third engagement portion 46 is formed in an outer circumference of the adapter 4. The first engagement portion 31c is non-rotatably inserted in the engagement hole 12b of the first bracket 1. The third engagement portion 46 is non-rotatably inserted in the engagement hole 12b of the second bracket 2.

A damping assembly for a pivoting stowage bin includes a rotary hydraulic damper that is mounted on the pivot axis of the stowage bin. The rotary hydraulic damper includes a damper body that receives a rotor having at least one vane moved through contained hydraulic fluid. Preferably, an exterior bearing surface on the damper precludes the active damping elements from radial loads, while a distributed attachment of the rotor to the pivoting bin enables reduced torque loads. The damper can include an integrated flow-control valve for controlling the opening rate of the pivoting bin as well as an integrated mechanical stop for the bin.

A rotary damper comprises a casing fixable to a structure and which comprises a wall which surrounds a chamber filled with a viscous fluid and has an inner surface facing the chamber. A cover is mounted and welded on a shoulder surface of the wall of the casing in such a way as to close the chamber in a sealed manner. A rotor which is mounted rotatably on the casing and comprises a disc portion, adapted to rotate within the chamber, and has a shaft portion extending axially from the disc portion and emerging through the cover so as to be operationally associable with a movable member. The cover has peripherally a collar-like protuberance, extending along the entire perimeter of the cover and coupled to the inner surface of the wall of the casing in such a way as to oppose the infiltration of the viscous fluid between the collar-like protuberance and the inner surface of the wall.

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.

An assembly to pivotally connect an external vehicle closure panel to a vehicle body includes a first hinge member that is constructed to be mounted to one of the external vehicle closure panel and the vehicle body, a second hinge member that is constructed to be mounted to the other of the external vehicle closure panel and the vehicle body, a shaft that is constructed to pivotally connect the first hinge member to the second hinge member, and a viscous rotary damper. The damper includes a cover, a rotor, and a viscous material. The shaft connects to the rotor such that rotation of the external vehicle closure panel between a closing position and an opening position causes relative motion between the rotor and the cover of the viscous damper to provide a resistance for controlling the velocity of the external vehicle closure member.
