A hinge has a side part fixable on a wall and a hinge part, which is pivotable in relation to the side part and is fixable on a door. Two levers are provided on the side part and the hinge part, which are each rotatably mounted on the side part and on the hinge part, and a linear damper having a housing and a piston rod is arranged in the side part.

A fluid damper hinge using a fluid damper only and a damper hinge using the fluid damper in combination with a torsion damper, used especially in relation to an opening and closing element such as seat lid and seat for western-style toilet, wherein both have a simple structure, do not require time for assembly and can be manufactured at a low cost.

Disclosed is a door hinge having a buffering function, including: a casing within which a damper is disposed in an axially movable manner, an end portion of a piston rod at the front end of the damper being fixedly connected to the casing; a hinge cup; a linking member A with a right end rotatably disposed inside the casing via a first rotating shaft and a left end rotatably connected to the hinge cup via a third rotating shaft; and a connecting member B with a right end rotatably disposed inside the casing via a second rotating shaft and a left end rotatably connected to the hinge cup via a fourth rotating shaft. The end portion at the right end of the linking member A or the connecting member B is disposed corresponding to the rear end of the damper.

The present disclosure a hinge blade structure comprises two hinge blades, a connection sleeve, a fixed rod, a screw sleeve, a plug, a damping positioning pull rod, and an air cylinder. The damping positioning pull rod and the air cylinder are both disposed in the connection sleeve and disposed between the fixed rod and the plug, the air cylinder is relatively secured to the plug, the damping positioning pull rod is relatively secured to the screw sleeve, the damping positioning pull rod is slidably connected to an inner side of the air cylinder along a length direction of the connection sleeve, the damping positioning pull rod and the air cylinder cooperate to define an air chamber, the air cylinder comprises an air chamber vent through hole and an air inlet, and a resistance force generated between the air chamber and the damping positioning pull rod achieves positioning.

The present invention concerns a piston for a damping device (2000), in particular for doors or windows, wherein the piston comprises a first half-piston (2510) and a second half-piston (2511), wherein the piston is configured for use with a first half-cylinder (2410) and a second half-cylinder (2420), wherein a first volume (2430) is included between the first half-piston (2510) and the first half-cylinder (2410), wherein a second volume (2440) is included between the second half-piston (2511) and the second half-cylinder (2420), and wherein the piston (2500) is provided with a hole (2550) for the passage of a fluid (1210) between the first volume (2430) and the second volume (2440). The invention furthermore concerns a damping device and a damped return device comprising the piston.

A damper for fittings for furniture or household appliances has a housing in which a piston connected to a piston rod is guided in a linearly displaceable manner, the piston dividing an interior space in the housing into two chambers, wherein at least one flow channel is formed on or in the piston, which flow channel connects the two chambers to one another, wherein a throttle element is provided, which, in a damping position, keeps the cross-section of the at least one flow channel small when the piston moves in a first direction in order to generate high damping forces, and when the piston moves in the second direction opposite to the first direction, increases the cross-section of the at least one flow channel for reducing the damping forces by a movement of the throttle element.

A hinge assembly for an associated appliance door includes an arm and a lever pivotally connected to the arm. The lever and arm are adapted to pivot relative to each other about a main pivot axis between a first position that corresponds to a closed position of the associated appliance door and a second position that corresponds to an opened position of the associated appliance door. A slide link is located adjacent the lever. A damper engagement structure is connected to the slide link. A biasing system urges the arm and lever toward the first position. A damper system includes a damper that damps pivoting movement between the arm and the lever for at least part of the movement between the arm and the lever when the arm and lever pivot relative to each other from the first position toward the second position.

A damper assembly is provided for a toggle type hinge with a mounting flange (13) and an arm assembly (11) pivotally connected thereto. The assembly comprises a damping device (16) that is actuable along a linear axis and a housing (20) mounted on the mounting flange to retain the damping device. The assembly further comprises means for converting pivotal movement of the hinge into linear actuation of the damping device. This comprises an actuating lever (21) connected to the damping device and engageable with the hinge arm assembly via a first camming mechanism causing the actuating lever to rotate in response to pivotal movement of the hinge arm assembly. A second camming mechanism causes linear displacement of the actuating lever in response to its rotational movement.

A damping device includes a housing, a piston and a controller. The housing defines a chamber filled with a damping medium. The piston is movable in the chamber and includes a passage for allowing the damping medium to pass through. The controller includes a control member and a resilient member. The control member is capable of being moved toward the passage of the piston or closing a portion or all portions of the passage of the piston in response to a speed of the piston.
