A power door system for actuating door panels between closed and opened positions. An operator arm telescopically supports a push rod. A housing is secured to the operator arm. A spring pin extends through apertures in the arm and the push rod. A release cable extends from the housing and is movable to retract the pin, permitting inter-telescoping motion of the push rod relative the operator arm, in turn permitting manual displacement of the doors. A compression spring supported within the housing influences the pin into engagement with the operator arm and push rod. A locking pin and guide is incorporated into a cable mounting guard below the spring pin, the locking pin displacing with the spring pin to a retracted position in response to actuation of the release cable, a successive actuation of the release cable releasing the spring pin and lock pin to reengage the apertures in the arm and the push rod.

A door operator system and a method for moving a door leaf between a closed and open position utilize a door operator and a supervise unit. The door operator includes a control unit, a presence sensor, activation sensors, and a drive unit. The drive unit is connected to the door leaf and moves the door leaf between the open and closed position to achieve a plurality of operational states. The presence sensor is configured to monitor a risk area and send presence data associated with an object detected in the risk area to the control unit. The activation sensors are configured to monitor respective activation areas near the door leaf and send activation data associated with an object detected in the respective activation areas to the control unit. The control unit controls a movement of the drive unit based on the activation and presence data.

A door control device includes: a speed control unit configured to perform speed control of an electric motor that drives a door; a speed detection unit configured to detect a speed of the door; and an obstruction detection unit configured to detect obstruction between the door and a door pocket, upon a value of the speed of the door detected by the speed detection unit decreasing by a first predetermined value or more with respect to a speed command value in the speed control during a door opening operation of the door.

A control system for a sliding door operator system (1) having at least one sliding wing (12, 14) and a door header (16) is provided. The control system comprises a first sensor (20a) configured to define a first activation zone (A1), a first wing presence zone (W1) and a first side presence zone (S1). The system further comprises a controller (30) configured to evaluate data from the first sensor (20a) for controlling the operation of the at least one sliding wing (12, 14) in the sliding door operator system (1).

A vehicle includes a cabin and a track assembly. The track assembly is coupled to a portion of the cabin. The track assembly includes a rail assembly. The rail assembly defines an interior aperture. The interior aperture is inaccessible from a top side, a first lateral side, and a second lateral side of the rail assembly. The rail assembly defines a first external channel in the first lateral side and a second external channel in the second lateral side. The first and second external channels receive a carriage power conductor and a carriage data conductor, respectively.

Methods and apparatus to wirelessly interlock doors are disclosed. A door system includes a user interface to receive interlock configuration data input from a user, the interlock configuration data to define an interlock condition to be satisfied before a first door is to undergo an operation, the interlock condition associated with a current state of a second door. The door system includes a first wireless transceiver to receive a signal from a second wireless transceiver associated with a second door. The method includes a door operation controller to at least one of (1) implement the operation of the first door in response to a request when the current state of the second door satisfies the interlock condition, (2) ignore the request, or (3) not execute the operation of the first door in response to the request when the current state of the second door does not satisfy the interlock condition.

An automated window shutter assembly includes a pair of shutters that is each movably positioned on an exterior wall of a building. Each of the shutters is positionable in an open position or a closed position. A housing is coupled to the exterior wall of the building and the housing is positioned above the window. A pair of screws is each rotatably positioned within the housing and each of the screws is rotatable in a closing direction or an opening direction. A drive unit is positioned within the housing and the drive unit engages each of the screws. The drive unit is turned on to rotate each of the screws in the closing direction or the opening direction. A plurality of engagements each threadably engages a respective one of the screws. Each of the engagements is coupled to a respective one of the shutters for opening and closing the shutters.

A device for the sliding movement of doors and wardrobe doors (12) provided with at least two doors (14,16) or (62, 64, 66) sliding so as to move along respective and parallel guides (18) and (18) fixed near the front edge of the upper base (20, 60) of said wardrobe, comprising: at least one pair of carriages (22), provided with at least one wheel or roller (32), fixed to the inner front of each door (14) and (16) at or near the respective upper edge; a plate-like element (22) for the direct attachment of at least one of the carriages (22) to the doors (14) or (16); at least one frame with an inverted U cross-section (46), and/or (46) supporting a wheel or roller (32); opposite air pistons (24) fixed to the end of the guides (18) along which the wheels or rollers (32) of the carriages (22) slide for the cushioned stop at the end stroke upon closing and opening of said carriages, and thus of the doors (14) and (16). Said device comprises a support (30) housing a piston (40) surmounted by an integral pincer or elastic clamp (44), said support (30) is fixed to at least one of the frames with an inverted U cross-section (46) or (46).

A fitting assembly has a device for securing against operating errors that has a first protrusion which can be moved relative to a second protrusion by means of a first operating rod assembly. A buffer can be provided between the end sides of the first protrusion and the second protrusion. The first protrusion can be a cylinder and/or the second protrusion can extend in an elongated manner. The fitting assembly can have an anti-lifting device with a third protrusion which prevents a lifting of the first leaf. The fitting assembly has multiple carriages and multiple sliders in order to position leaves of the window or the door into their slide position in parallel with the main plane of the window or the door. In the blocking position, the leaves can be pressed against a fixed frame of the window or the door via the fitting assembly with multiple carriages and multiple sliders, in order to reliably seal the window or the door.

An automated window shutter assembly includes a pair of shutters that is each movably positioned on an exterior wall of a building. Each of the shutters is positionable in an open position or a closed position. A housing is coupled to the exterior wall of the building and the housing is positioned above the window. A pair of screws is each rotatably positioned within the housing and each of the screws is rotatable in a closing direction or an opening direction. A drive unit is positioned within the housing and the drive unit engages each of the screws. The drive unit is turned on to rotate each of the screws in the closing direction or the opening direction. A plurality of engagements each threadably engages a respective one of the screws. Each of the engagements is coupled to a respective one of the shutters for opening and closing the shutters.
