A method for controlling a motorized flap assembly of a motor vehicle, wherein the flap assembly includes a pivotable flap, a drive arrangement associated with the flap and a control arrangement for controlling the drive arrangement. A position sensor for determining position information related to the position of a selected component of the flap assembly is associated with the flap assembly and movement commands for the drive arrangement are generated by the control arrangement based on the position information, to close the flap to an upright closed position during a motorized closing process and to open the flap to a horizontal open position during a motorized opening process. The pivoted open flap may be occupied by an object or a person. The position sensor detects the object or person based on at least one occupancy criterion and an occupancy reaction is triggered depending on the detected occupancy state.

An emergency door closing device that can be installed upon existing doors and hinges to automatically close doors in the response to smoke and fire. The improvements incorporated therein include a hinge cam pivot member that attaches to an existing hinge member of a door and produces a moment force about the existing hinge member allowing a reduced force necessary to pivot the door into a closed position. Further, a novel spring, cam, and lever system is incorporated to activate the moment force to close the door.

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 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.

A door system comprises a door frame adapted to be mounted within an opening, a door pivotally attached to the door frame, an AC/DC converter configured to be electrically connected to an AC power unit operably associated with the door system, a slot in the door, a pre-wired receptacle disposed in the slot, and a DC electric device removably disposed in the pre-wired receptacle and electrically connected to the AC/DC converter through the electrical connector of the pre-wired receptacle. The pre-wired receptacle comprises an electrical connector electrically connected the AC/DC converter.

A hinge (1) for connecting a door to a household appliance compartment is described, comprising a fastening bracket (2) adapted to be fastened to the compartment of said household appliance, a movable support (3) to rotatably constrain said door to said fastening bracket (2), an activating arm (5) coupled to said fastening bracket (2), movement means (6) adapted to move said activating arm (5), said activating arm (5) comprising a first end portion (5a) adapted to be constrained to said door, and a second end portion (5b) fitted to be coupled to said movement means (6) to move said activating arm (5) between an open position (P2) of the door and a closed position (P1) of the door, said movement means (6) comprising an electric motor (10) and reversible connecting means (9) to couple and decouple selectively said electric motor (10) and said second end portion (5b), said hinge (1) being configured so that when said electric motor (10) is coupled to said second end portion (5b), the electric motor (10) causes the movement of the activating arm (5), whereas when said electric motor (10) is decoupled from said second end portion (5b), the movement of the first end portion (5a) occurs independently of the electric motor (10) to allow a user to freely move the door.

An entrance system (1) comprises a swing door member (10) having a door leaf (12), and a sensor unit (S1; S) mounted to the door leaf (12), the sensor unit comprising a door angle sensor (S1). The entrance system (1) further comprises an automatic door operator (30) having a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and a linkage (40) connected to the automatic door operator (30) and the door leaf (12) for transferring torque generated by the motor (34) to the door leaf (12). The automatic door operator (30) is operable in a learn mode (60) and an operational mode (70). In the learn mode (60), the controller establishes a linkage reduction curve (65) relating a movement of said door member (10) with the torque required to move the door leaf (12) through different angles (). The door leaf angles are determined from measurement readings of said door angle sensor (S1). In the operational mode (70), the controller compensates for a non-linear torque transfer characteristic of the linkage (40) by applying the linkage reduction curve (65) to control the motor (34).

An apparatus comprising a baseplate configured to be coupled to an interior side of an inswing door adjacent a pivot edge of the door; a rotatable closing arm with a first end and a second end, the second end coupled to a motor, the motor configured to be engaged in response to receipt of a signal from a remote electronic device; and circuitry electrically coupled between a power supply and the motor, the circuitry configured to wirelessly send and receive information to and from the remote electronic device.

Provided are a cab for a work machine and a work machine capable of preventing a door from opening against an operator's intention. The cab includes a cab body, a door, and a gas spring. The cab body is formed with a doorway. The door is rotatably supported on the cab body. The door opens and closes the doorway. The gas spring biases the door in the closing direction.

An apparatus includes a control unit. The control unit is configured to control an automatic flap and/or door. The flap and/or door is automatically transferrable from an open position into a closed position by at least one actuator. The flap and/or door is configured to press against a seal when in the closed position. In relation to a closing operation of the flap and/or door, the control unit is configured to determine time information in relation to an open state time duration during which the flap and/or door was in the open position before the closing operation. In relation to a closing operation of the flap and/or door, the control unit is also configured to operate the at least one actuator configured for the closing operation as a function of the time information.
