Abstract:
In an arrangement for damping and/or retarding a movable part, including a housing with a pressure member slidably supported in the housing and a cylinder piston unit arranged in the pressure member and in the housing wherein the housing includes a mounting flange with a support surface provided with at least two throughbores, the mounting flange has at least two spaced guide surfaces which are oriented at least approximately normal to the support surface, the guide surfaces delimiting an adapter area at several sides thereof. The damping arrangement can be used and installed rapidly and accurately to various types of hinges.
Abstract:
A damping device includes a cylinder in which a resilient member and a piston are received. A cover assembly and a seal member seal the cylinder and damping medium is filled in the cylinder. The piston includes a piston body, a connecting portion connected with one end of the resilient member, and a neck portion connected between the piston body and the connecting portion. The piston body has an opening penetrating through the piston body. A control valve is movably mounted to the neck portion to control the opening during operation. A piston rod has one end connected with the piston body and another end extending out from the cylinder. A damping member is located between the piston and the cover assembly. The traveling velocity of the piston is controlled by the control valve to close or to open the opening through which the damping medium passes.
Abstract:
A furniture hinge has a door stop part, which includes an insertion cup and is attached on a furniture door, at least one pivoting arm that is connected to a furniture body being supported on the door stop part. A damping device including at least one damping cylinder engages in the door stop part. Each damping cylinder is disposed at least partially in a bore of the furniture door. The cylinder axis of the damping cylinder extends substantially perpendicularly to the door plane. The damping cylinder is moved during the pivoting thereof into the locking position of the furniture door by the pivoting arm.
Abstract:
In the breakdown preventive mechanism of a rotary damper, when the upper rotor is rotated in one direction, a communication path is formed between the valve body and the lower rotor, and the pressure in the pressure chamber is formed between the lower rotor and the lower housing is lowered, and rotation is easily performed. When the upper rotor is rotated in another direction, the viscous fluid does not flow between the valve body and the lower rotor, and the pressure in the pressure chamber formed between the lower rotor and the lower housing is raised. As a result, the viscous fluid pushes down the relief valve and a cage type relief valve by resisting the elastic element, and thereby prevents breakdown of the rotary damper.
Abstract:
A self-adjusting door closer is disclosed. The door closer is self powered and includes a control unit to intelligently control a valve within the door closer to vary the operating characteristics of the door closer as needed. The controller includes a position sensor to determine a position of the door, and at least one input switch to enable user selection of at least one door closer parameter for an installed door closer. The control circuitry is operable to set the valve in response to the user selection of the door closer parameters, and the position of the door, in order to control force exerted by the door closer on the door. A generator can be provided to provide electricity to power the controller and store power to operate the controller.
Abstract:
A sliding door with a door leaf, which is suspended from at least one carriage and guided to be displaceable along a roller rail profile disposed at a wall or at a ceiling. The sliding door includes a closing device, which is suitable to displace the door leaf into a closed position in a decelerated manner. The closing device is disposed at the door leaf and includes a first and a second spring-damper element, which are disposed to be counter-directional to each other. The second spring-damper element is suitable to displace the door leaf into an open position in a decelerated manner.
Abstract:
A door closing mechanism which comprises a hydraulic rotation damper 5, comprising a closed cylinder cavity 20 within a cylinder barrel 19, a rotational damper shaft 22 which extends into the cylinder cavity 20, a piston 21 dividing the cylinder cavity 20 into a first side 20a above the piston 21 and a second side 20b below the piston 21, a one-way valve 33 allowing fluid flow from said first side 20a to said second side 20b of the cylinder cavity 20, and a fluid passage 31 between said first and second sides 20a,20b of the cylinder cavity 20, with a flow restrictor, in particular in the form of a needle valve 32, adjustable through an orifice in the cylinder barrel 19, wherein said second side 20b of the cylinder cavity 20 and said orifice are at opposite sides of the flow restrictor.
Abstract:
Universal impact-hinder device, comprising a body (1); a guiding pin (4) arranged at the closed first end of an inside cylindrical cavity of the body (1), a spring (7) on the guiding pin (4); a ring (5) at the opposite end of the cavity; and a piston having a T-shaped head and an inside cavity in which the spring (7) is supported, which piston can move until the ring (5), while the guiding pin (4) is within the inside cavity of the piston. The T-shaped head is provided with a groove and a movable O-ring (6) within that, having two end positions in the groove. In first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow-through capacity, in second end position an orifice (21) between the cavity of the body and the groove determines a greater second flow-through capacity.
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 neat its end positions.
Abstract:
A damping device includes a cylinder (11) in which a piston (10) is housed for reciprocable movement. The piston has a skirt (12) which expands resiliently outwardly when the piston is moved in the direction of arrow A to provide a frictional damping force. The interior of the cylinder is undercut at its distal end (13a) to allow the skirt to relax.
