A door component has a controllable rotary damper and two connector units which can be moved relative to one another. One of the two connector units can be connected to a load-bearing construction and the other one can be connected to a movable door device of a vehicle, in order to damp a movement of the door device between a closed position and an open position in a controlled manner. Two mutually engaged spindle units are arranged between the two connector units, one spindle unit being a threaded spindle and the other being a spindle nut. A first spindle unit is fastened rotatably on a coupling rod connected to one of the connector units. A magnetorheological transmission device is arranged between the coupling rod and the first spindle unit, in order to brake a rotational movement of the first spindle unit as required.

A device has at least two components which are movable relative to one another. The first component is equipped with a rotary receptacle and wherein the second component is rotatably received on the rotary receptacle. A third component is coupled to the second component. Two connection units which are movable relative to one another and a controllable braking device are included, wherein the braking device is designed as a controllable rotary brake in order to provide controlled damping of a movement of a door device between a closed position and an open position. The first connection unit is formed on the first component, and the second connection unit is pivotably coupled to the third component. The pivot axis is oriented transversely with respect to an axis of rotation of the second component.

A hinge for mounting a door on a piece of furniture or the like comprises a hinge arm, a box connected to the hinge arm by an articulation system comprising a plurality of movable connecting levers and seven articulation axes, spring means acting in closing direction of the hinge, and a damping device having an actuation member linearly movable according to a longitudinal axis; the damping device is at least partially enclosed between the side walls of the hinge arm, and the actuation member of the damping device extends at a front end of the hinge arm facing the hinge box for contacting thrust element of one of the connecting levers of the articulation system or integral with one of the connecting levers or with the hinge box at least in a range near the closing position of the hinge.

A device has at least two components that can be moved relative to each other. A drive device is provided with a drive housing and a drive shaft in order to bring about a relative movement of a first component to a second component. If the drive shaft is coupled in a rotationally fixed manner to the second component, the drive housing is rotatably accommodated on one of the two components and can be coupled by an actuator in a rotationally fixed manner to the first component and can be decoupled therefrom. If the drive housing is coupled in a rotationally fixed manner to the second component, the drive shaft can be coupled by an actuator in a rotationally fixed manner to the first component and can be decoupled therefrom.

A hinge arrangement having a first hinge part and having a second hinge part, which are connected to one another such that they can pivot, a first hinge pin being formed on the first hinge part, on which a first hinge sleeve is pivotably mounted, which forms a first sliding bearing with the first hinge pin, a dimensionally stable support part being connected to the first hinge sleeve. A first axial protrusion is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove of the first hinge sleeve, wherein a circumferential first side wall of the first groove together with the first axial end face and an inner side of an end cover fixed at the end of the first hinge sleeve delimits a working space which is filled with a damping fluid for damping a relative movement of the first axial protrusion with respect to the first groove.

Included are: a main body including an installation part in which a cartridge housing a liquid for treating a test substance contained in a specimen is installed and a detector configured to detect the test substance treated with the liquid within the cartridge installed in the installation part; a lid part arranged rotatably on the main body about a shaft so as to open and close the installation part; a biasing part biasing the lid part in an opening direction; and a plurality of regulators each generating resistance against a biasing force in the opening direction at different timing during an opening motion of the lid part.

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).
