Abstract:
The invention refers to a slow-down mechanism that prevents moving furniture units like covers, doors, etc. hitting the other side and making noise in cases of fast opening and closing actions towards fixed furniture units and thus enabling soft opening and closing actions for such moving furniture units, comprised of at least an arm (2), a bowl (3) and a internal and external knuckle element (6, 5) connecting the arm and bowl, and located inside the hinge. The invention refers especially to the capability to canceling the damper (18) belonging to the above-mentioned slow-down mechanism inside the hinge (1) and adjusting the damper's stroke depending on the weight of the moving furniture.
Abstract:
Damping device for damping motion of movable furniture parts. A piston mounted in housing in longitudinally displaceable manner which, due lo displacement, forms two variable-size working chambers on opposite sides with damping medium. Via overflow-connection, throttled transfer of damping medium is possible between two working chambers. Piston plunger, fed selectively, is connected on one side of pislon. Via the outer end of piston plunger, the motion of the furniture part to be damped is transferred to the piston. On side of piston, an elongated adjustment shaft is connected to the piston plunger. Free end of plunger is fed in sealed manner out of front face lying opposite front face that is sealed on the piston plunger side. The end of adjustment shaft engages with a passage duct connecting two working chambers and forms a variable-sized throttle cross section in the passage duct, making adjusting motion of shaft relative to piston.
Abstract:
In an acceleration and deceleration device which includes at least one energy storage device and a cylinder with at least one piston movably disposed in the cylinder and moved therein by a carrier element and a sliding door including a slidable door panel provided with an acceleration and deceleration device, a second carrier element is provided guiding either the first piston or the second piston for movement in the cylinder so as to control the movement of pistons and of the sliding door near its end positions.
Abstract:
A hinge damper is configured to be adhered to a door hinge of the furniture having a door to attenuate impact and is designed in a small size but to attenuate a large amount of impact. In the hinge damper, first and second seals are formed in an oil seal to prevent air from being introduced. A cross rib is formed on a piston to absorb a larger amount of impact with a small size. The hinge damper can be sized as small as a size of a screw used for fixing the hinge.
Abstract:
A catcher (2) provided in a door frame H′ for capturing a striker body 1 moved from a near front side F when a door D′ is rotated toward a reference position; a braking device (5); and a linkage device (3) for both are provided. The catcher (2) is provided to be reciprocatingly rotatable between a standby position and a rotated position, captures the striker body (1) at the standby position, and rotates forward to the rotated position. Braking of the braking device (5) is applied to a rotation toward the rotated position of the catcher (2) through the linkage gear member (30).
Abstract:
The hinge structure for a furniture with a foldable shelf (1) reversibly turnable downwards from a closing position of the furniture to a substantially horizontal opening position comprises a first and a second rocker arm (2, 3) hinged at their ends by means of a first, second, third and fourth pin (4, 5, 6, 7) to a first plate (8) able to be fixed to a stationary portion (9) of the furniture and to a second plate (10) able to be fixed to the shelf (1), first decelerating means (11) mainly of the final portion of the opening stroke of the shelf (1) independently from second decelerating means (12) mainly of the initial portion of the opening stroke of the shelf (1).
Abstract:
A rotatably supported door including a hinge including a stationary hinge portion, a leaf hinge portion, which is pivotable about the stationary hinge portion, and a rotating shaft passing through the stationary hinge portion and the leaf hinge portion. The rotating shaft cooperates with an opening and/or closing damping device.
Abstract:
A door closer with a self-powered control unit is disclosed. The control unit for the door closer includes a drive gear configured to rotate in response to movement of a door, and a chain arranged to cooperate with the drive gear to produce linear motion in response to rotation of the drive gear. At least one gear creates rotational motion from the linear motion of the chain to turn a generator and generate electricity to power the control unit. In some embodiments, a set of clutch gears is disposed between the chain and the gear creating the rotational motion from the chain so that only one direction of the rotational motion is transferred to the generator in response to movement of the door in any direction. The control unit can additionally include a power management circuit to store energy from the generator.
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:
A damping device comprises an axle, a housing, a unidirectional member, and a damping oil. The unidirectional member in cross section is formed like a T-shape, and a top portion thereof is formed as an arc to cooperate with the housing's inner wall. Where the unidirectional member contains a U-shaped slot defines oil holes interlaced with the gap of the first slot wall. The lifting of the cover is free from damping and the closing thereof performs a well damping capability. Even only a narrow angle is lifted, a delicate damping is still achieved. The undersized unidirectional member concurrently guarantees the structural strength. The diminished cross-section of the unidirectional member contributes to a smaller U-shaped slot. Therefore, while satisfying the turning angle, the thicknesses of the U-shaped slot's wall and the obstructing wall are assured to greatly prolong the using life of the present invention.
