A hinge including: a first leaf assembly accommodating a portion of a first panel having a first cut-out section, the first leaf assembly including a first insert component which is tight fittingly receivable within the first cut-out section; a second leaf assembly, hingedly coupled to the first leaf assembly, for accommodating a portion of a second panel having a second cut-out section; one or more biasing components to bias the hinge toward a closed position; and a dampener to slow movement of the first and second leaf assemblies to the closed position, a first portion of the dampener is located within the first insert component and a second portion is configured to at least partially retract within the first insert component when coining into contact with the second leaf assembly during movement, a second portion of the dampener extends and retracts along an axis coplanar with the first panel.

A vehicle interior component is disclosed. The component may comprise a base and a door moveable along a track between open and closed positions. The door may move in a direction transverse to the track between offset and biased/centered positions. The door may comprise a spring to bias the door toward the biased position. The spring may move first and second arms of the door against the base to prevent door rotation. The door may move along a biased path and first and second offset paths parallel to the biased path. The component may comprise a mechanism configured to move the door from the open position to the closed position along the offset paths and the biased path. The component may comprise at least one of a console, a floor console, a center console, an instrument panel, a door, a cockpit, a storage compartment.

A door closer having an elongate housing for mounting in a door leaf or door frame, the elongate housing having opposite forward and rear end parts, a plunger disposed in and movable along the housing, the plunger including a ferromagnetic material, a spring biasing element disposed in the housing and applying a first biasing force to bias the plunger inwardly of the housing and away from the forward end part and towards the rear end part, a tension member having a first end connected to the plunger and a second end connected to an anchor element assembly, the anchor element assembly comprising a mounting member for mounting in the other of the door leaf or door frame, the tension member and anchor element forming a tension assembly which extends through the forward end part.

A braking device for a movable door leaf comprises an electric motor operated as a generator, whose shaft is rotatable through a movement of the door leaf and at whose terminals a movement-dependent motor voltage is created and a brake circuit to which the motor voltage is applied or could be applied and which can be short-circuited via the motor terminals to dampen movement of the door leaf. In addition, the braking device comprises an emergency brake circuit to which the motor voltage is applied or applicable and via which the motor terminals can be short-circuited to dampen a movement of the door leaf. In doing so, means are provided which are designed to detect the presence of a malfunction of the brake circuit and to short-circuit the motor terminals via the emergency brake circuit when the presence of a malfunction of the brake circuit is detected.

In a method for the commissioning of a door or window closer which comprises an energy accumulator, a damping device with an electric motor being operable as a generator and a transmission element, the leaf is opened and/or closed at least once in a teach-in process, the angular position of the motor shaft is detected during opening and/or closing, a functional relationship is determined between the angular position of the motor shaft and an angular position of the rotatable leaf at least over an area of the opening width of the leaf and the functional connection is automatically taken as a basis for a subsequent actuation of the electric motor for the damping of the closing movement of the leaf.

A pneumatic control device of auto door includes a first directional control valve configured to control a direction of a compressed air supplied to a door cylinder for opening and closing a door, a door detection sensor configured to detect an open/close state of the door, first and second exhaust lines respectively connected to first and second outlet ports of the first directional control valve, and second directional control valves installed in the first and second exhaust lines respectively to operably exhaust the compressed air exhausted from the first and second outlet ports according to an emergency stop signal, and capable of changing positions to reduce an exhaust speed of the compressed air in case that the door is not completely open or closed when an operation signal is generated after the emergency stop signal.

A positionable hidden hydraulic hinge configured for installation of a door is provided. The positionable hidden hydraulic hinge includes a non-movable device body configured to be connectable with a door frame, a rotatable device body configured to be connectable with a door leaf, and a hinge configured to connect the non-movable device body and the rotatable device body. The rotatable device body includes a bearing guiding base having a guiding groove and a hydraulic chamber body. The positionable hidden hydraulic hinge also includes a linkage assembly configured to penetrate throughout the hinge. Two ends of the linkage assembly are configured to pivotably connect with the non-movable device body and an internal mechanism of the rotatable device body, respectively. A first end of the bearing guiding base is fixedly connected with the hinge, and a second end of the bearing guiding base is connected with the hydraulic chamber body.

A door system comprises a door frame adapted to be mounted within an opening, a door pivotally attached to the door frame, a power converter such as an AC/DC converter operably associated the door frame, and a DC electric device mounted to the door and electrically connected to the AC/DC converter. The AC/DC converter is configured to be electrically connected to an AC power unit operably associated with the door system.
