The lateral boundaries (2) have a module rail (6) that is close to the ground and is provided with receptacles for functional elements and/or functional modules of the access control device, more particularly with specifically adapted receptacles for functional elements and/or functional modules of the access control device, preferably in a predefined grid.

A vehicle side door opening/closing device includes a motor, a gear case to which the motor is fixed and which is fixed to a side door, a speed reducer built in the gear case, an output gear provided to the speed reducer, a rack of which an end portion is pivotably supported to a vehicle body and which is provided with a rack gear, and an engagement holding unit connected with the gear case and movably supporting the rack while constantly keeping an engagement allowance between the rack and the output gear. The side door is moved in an opening direction by pushing the rack and in a closing direction by pulling the rack respectively following the rotation of the output gear. The engagement holding unit rotates around a rotation center of the output gear by a swing of the rack following the opening/closing operation of the side door.

A bidirectional door opening structure includes a first door configured to be opened by rotating about a first end of a vehicle that is adjacent to a roof of the vehicle, a second door configured to be opened by rotating about a second end of the vehicle that is adjacent to the roof of the vehicle, the second end being opposite the first end, a drive unit disposed at a portion of the roof between the first door and the second door, and a controller configured to receive a door drive request with respect to the first door or the second door and to apply a driving force to at least one of the first door or the second door, wherein the drive unit comprises a spindle unit, a latching lever, and a rotation lever.

A door opening and closing device for a refrigerator includes a door coupled by means of a hinge unit to a main body defining a storage compartment therein, a gasket disposed between the door and the main body to provide a hermetic seal therebetween, and an opening and closing unit for opening and closing the door with respect to the main body, wherein the opening and closing unit includes a drive unit for generating a driving force, a gasket separation mechanism for pushing the main body using rotational force transmitted from the drive unit to separate the gasket from the main body or the door, and a door rotating mechanism for rotating the door using the rotational force transmitted from the drive unit.

A drive arrangement for motorized adjustment of a cargo-space-tailgate arrangement of a motor vehicle the cargo-space-tailgate arrangement including a cargo-space tailgate adjustable between an open position and a closed position, the drive arrangement includes an electric drive, for providing a drive force, and a control arrangement for activating the electric drive. The drive arrangement includes an output element and a drive coupling. The output element transmits the drive force to the drive coupling for motorized adjustment of the cargo-space tailgate. The control arrangement activates the drive in an adjustment routine for motorized adjustment of the cargo-space tailgate to assist an actuation action introduced manually the cargo-space tailgate, and the control arrangement activates the adjustment routine based on an activation preset that is dependent on at least one friction parameter of the drive.

Mechanism for the movement of a wing of furniture with a downward folding opening, designed to be placed on one side of the furniture item, the mechanism being contained in a box consisting of two half-shells, and including a hinge including a plurality of levers, articulated one in relation to the other, to the box and to the wing for the movement of the latter, one of the levers being able to slide in a track formed in the box, another of the levers being able to rotate around a fulcrum point provided on the box and acting with one of its ends on the front side of a linear slider, the rear side of which acts on one end of a rocker lever, whose other end acts on.

A method (1000) for testing of a door operator (100), said door operator (100) being configured to via a mechanism (104) move at least one door leaf (200) between an first position and a second position, the door operator (100) comprising a first drive unit (102) configured to optionally move the door leaf (200) into said first position, said door operator (100) further comprising a control unit (103) connected to a sensor (105).

An overhead door system is disclosed, which includes a first track and a second track mounted on opposite sides of an opening. Each track has a vertical portion, a transition portion, and a horizontal portion, with the transition portion being between the vertical portion and the horizontal portion. An overhead door engages the first and second tracks on opposite sides of the overhead door and is movable along the first and second tracks between a closed, vertical position and a raised, horizontal position. A motor unit has a motor that is mounted above the horizontal portions of the first and second tracks. A rail is parallel to and disposed between the horizontal portions of the first and second tracks. The rail carries a carriage configured to move in a first direction to raise the overhead door and in a second, opposite direction to lower the overhead door. A connecting member is pivotally attached at one end near a top edge of the overhead door and attached at an opposite end to the carriage. A one-way bearing is disposed between the motor and the carriage. The motor, as it rotates in a first rotational direction, applies force to the carriage to move the carriage in the first direction to raise the overhead door. Nevertheless, owing to the one-way bearing, the motor, as it rotates in a second, opposite rotational direction, does not apply force to the carriage to move the carriage in the second direction to lower the overhead door. A kit to retrofit an overhead door system with a one-way bearing is also disclosed.

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.
