Abstract:
A rotary damper has a cylindrical housing. A rotor is rotatably supported inside the housing for rotation with respect to the housing by a first bearing and a second bearing. The second bearing has a greater length in the axial direction of the rotor than the first bearing. The rotary damper can be employed in an opening and closing mechanism for a vehicle door.
Abstract:
A door closing mechanism which includes a hydraulic rotation damper, having a closed cylinder cavity within a cylinder barrel, a rotational damper shaft which extends into the cylinder cavity, a piston dividing the cylinder cavity into a first side above the piston and a second side below the piston, a one-way valve allowing fluid flow from said first side to said second side of the cylinder cavity, and a fluid passage between said first and second sides of the cylinder cavity, with a flow restrictor, in particular in the form of a needle valve, adjustable through an orifice in the cylinder barrel, wherein said second side of the cylinder cavity and said orifice are at opposite sides of the flow restrictor.
Abstract:
A damping device for damping motion of a movably mounted furniture part or of a movably mounted furniture fitting component of a furniture fitting includes a piston arranged in a fluid chamber. A damping effect is caused by a relative motion between the fluid chamber and the piston and the piston assumes a pressed-in end position relative to the fluid chamber at the end of the damping stroke. The damping device has a locking device having a locking element that can be operated manually or by a tool in order to deactivate the damping effect. The relative position between the fluid chamber and the piston can be releasably locked in the pressed-in end position by the locking element of the locking device.
Abstract:
A deceleration device comprises a cylindrical container (14) housing at least one friction disc (16) against at least an internal wall of the cylindrical container (14), and a movable cursor (18), actuated by an external element, for the actuation of the friction disc (16), the friction disc (16) being bound to the cylindrical container (14) through constraint means which permit a roto-translational motion in order to acquire a further sliding contact surface in addition to the internal wall of the cylindrical container (14) at the end of the initial translation phase of the cursor (18) in which the friction disc (16) is subjected to a mainly or completely translational motion.
Abstract:
The hinge (1) for furniture comprises at least one deceleration device attached to the outside of the hinge box (4), an actuating lever (12) for the deceleration device, supported in oscillating fashion in the hinge box (4), and elastic return means to bring the actuating lever (12) back to an initial position, the deceleration device comprising a housing body (15) which extends peripherally along a side wall (9) of the box (4) and has means for fixing it to the side wall (9), the elastic return means being located on the housing body (15) outside the box (4) and providing at least one elastic arm (16) which protrudes into the inside of the box (4) through an aperture (17) in the side wall (9) of the box (4) to connect operatively with the actuating lever (12).
Abstract:
A rotation control device is configured so that a spring force of a torsion coil spring holds an attitude of a rotation body at a pre-advancement position corresponding to a post-return position (a), and a post-advancement position corresponding to a pre-return position (b), respectively. The rotation control device includes a first rotation part supporting one end of the torsion coil spring and supported on a fixed body so as to rotate as the rotation body rotates, and a second rotation part rotatably supported on the fixed body at a first rotation part side and supporting the other end of the torsion coil spring. When the first rotation part rotates, the second rotation part rotates together with the first rotation part. A wound portion of the torsion coil spring is most elastically deformed when the rotation body is at an intermediate position (c) between the position (a) and the position (b).
Abstract:
The invention relates to a damper for damping a rotational or linear movement of a component, preferably a component moveably mounted in the passenger compartment of a motor vehicle, having a damper housing, characterized in that at least one illumination source and/or at least one sensor, as well as an electrical connecting device for connecting the illumination source or the sensor to an electrical supply, are integrated into the damper housing.
Abstract:
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.
Abstract:
The present invention provides an adjustable hinged door closer, including a seat with the first and second cylinders, and a first and a second elastic linkage unit. A double-threaded regulator is incorporated onto the first connecting rod of the first elastic linkage unit, so as to change the compression of the spring and regulate the closing/restoring force of the door body. The double-threaded column of the double-threaded regulator has a double-thread that shifts to two thread pitches by just making one rotation, thus facilitating the fine-tuning easily. The elastic linkage unit and the regulator are structurally configured to be assembled externally, and then mated with the connecting seat of the door closer.
Abstract:
A damper assembly incorporating a bushing adapted to rotate within a wall structure and engage a post on a bin or other element to be controlled. The bushing defines a hub of an integral, coaxial rotor which rides within a fluid containing housing. The bushing and rotor rotate concurrently about a common axis during rotation of the bin or other device being controlled. The drag on the rotor thereby slows the rotation of the engaged post and the associated bin or other structure being controlled.
