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.

Provided is a rotary damper on which the timing for generating a damping torque can be set freely. Groove-like bypass passages (805) that are longer in the circumferential direction than vanes (501) are formed in the upper surface (803) of a torque regulation plate (8) arranged on the bottom part (201) of a cylindrical circular chamber (200). When the rotor (5) rotates in a first rotational direction R1, if both end faces (508a, 508b) of the vanes (501) are positioned within a range of the respective bypass passages (805), each area (218) and the corresponding area (217) are communicated via the corresponding bypass passage (805), enabling movement of a viscous fluid (6) from the area (217) to the area (218). Subsequently, if the rotor (5) rotates further in the first rotational direction R1 and one or both of the end faces (508a, 508b) of each vane (501) is outside of the range of the corresponding bypass passage (805), each area (218) and the corresponding area (217) are not communicated via the corresponding bypass passage (805), and the viscous fluid (6) is unable to move from each area (217) to the corresponding area (218).

Disclosed are systems and devices for controlling the closing of a door. A head unit is to be installed in a doorjamb, comprising a chamber filled at least in part with a shear thickening fluid. A piston is connected to a cap and configured to exert pressure against the shear thickening fluid in response to a force applied to the cap. The systems and devices provide an adjustable design that resists door slamming and aggressive closure, serving as a safety device as well as noise, damage and pet control around doors (preventing closure if desired). An install kit provides exact location, depth control and guide to place over the head unit to tap it into place with a hammer.

A sliding door system includes a door frame and a sliding door leaf that can move relative thereto. A catch is arranged either on the door frame or on the sliding door leaf, which can be coupled to a drive element of a feed device arranged on the respective other component. The feed device has a spring energy store and a cylinder-piston unit. The cylinder-piston unit has a piston that separates a displacement chamber from a compensation chamber. A passage cross-section between the displacement chamber and the compensation chamber can be changed in a load-dependent manner by a piston disk that can be applied at a piston end side. The tension force of the tension spring of a minimal effective length is between 1.5 and 3.5 times the total static friction force of the sliding door leaf and the resistance of the cylinder-piston unit at the maximum passage cross-section.

A furniture drive system includes: a support for mounting the system on a furniture carcass; an actuating arm device movably mounted on the support and to be connected to the movable furniture part; an electric motor to be connected to the actuating arm device to move sections of the actuating arm device; a drive device separate from the electric motor for exerting a force on the actuating arm device; an adjusting device for adjusting the force to be exerted by the drive device; and a control device for controlling the electric motor. The control device has a determining device for determining the force to be exerted on the actuating arm device, and the drive device has a damping device to dampen a closing movement and/or an opening movement of the actuating arm device. The determining device is designed to perform a damper analysis of the damping device.

A damper device set is provided which can mount a damper device on a door that is thin and has a constraint on the mounting position. A first fastening member is used to fix a mounting plate to a door. A second fastening member placed at a position different from the first fastening member in a thickness direction of the door is used to fix, to the mounting plate, a damper device including a case and a linear damper housed in the case. At least part of the linear damper overlaps at least part of the first fastening member in plan view of the door.

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 hinge includes a hinge arm, a hinge cup, at least one resilient member, and a retaining member. The hinge cup is pivotally connected with respect to the hinge arm and includes a receiving room. The resilient member is mounted in the receiving room of the hinge cup. The retaining member is mounted at the resilient member.

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 rotary hinge assembly includes a fluid chamber filled with a fluid and a constricted section with a throat area which is tunable by a throat tuner to control the fluid flow passing through the constricted section. Within the fluid chamber, a rotary connecting pin is mounted so that a first longitudinal end of the pin is connected to a door, and a second longitudinal end of the pin is concentrically and rotatably mounted within the fluid chamber. On the second longitudinal end, a vane is connected and adapted to rotate for displacing the fluid present in the fluid chamber towards the constricted section, when the rotary connecting pin undergoes the rotational movement in response to opening and closing of the door.
