A release for a power door system for actuating door panels between closed and opened positions. A linkage includes an operator arm telescopically supporting a push rod. A housing is secured to the operator arm. A pin extends through apertures in the arm and the push rod. A release cable extends from the housing and, in response to displacement, causes the pin to retract, 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 and preventing return displacement of the spring pin in response to a single pull retraction of the spring pin.

A track-guided power door operator used to simultaneously open a set of opposing hinged doors is disclosed. The door operator comprises a pair of articulated arm linkages, each pair of which is pivotally mounted at one end to a vertically oriented pivot pin at one end of a guide member and pivotally connected at the other end to a vertically oriented pivot pin of a yoke member of a translating carriage, which is engaged by a horizontal lead screw. Translation of the carriage member due to rotation of the lead screw causes lateral separation between the knuckles of the articulated arm pairs to cause doors contacted by the knuckles to rotate about their respective hinges. The door operator may include a control unit to control operation of the doors. The operator may further include magnetic latches to lock the doors closed.

A device for coordinated control and operation of double doors having a plate with a rectilinear motion that is associated with links with adjustable lengths that connect the plate to the double doors, with both the first and the second doors opened when one of the doors is opened and sequentially closed when one of the doors is closed.

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.

A telescopic mechanism and corresponding method for opening and closing sliding doors which allows obtaining a dimensional gain equal to the diameter of the pulleys including an intelligent control board, a motor, a system of pulley and belt linear guides which connect the panel A to Panel B, a lever system, arms, rotary union, shaft of rotation, which originate movements of extension and compression of a sliding structure comprising a chassis, Panel A and Panel B. The belt and pulley system includes a belt, a brake, wheels movable pulleys fixed to the chassis and static pulleys.

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.

A door opening and closing control device includes: one sensor configured to sense an entire detection region, the sensor including one or more transmitting elements configured to transmit a frequency modulated continuous wave (FMCW) type transmitted electromagnetic wave, two or more receiving elements configured to receive a reflected electromagnetic wave obtained by the transmitted electromagnetic wave being reflected by a target, and a calculation unit configured to calculate a distance to the target, a moving speed of the target, and an angle of the target with respect to the sensor using the transmitted electromagnetic wave and the reflected electromagnetic wave; a moving direction calculation unit configured to calculate a moving direction of the target detected by the sensor; and a door opening and closing control unit configured to control opening and closing of a door using the moving direction and the moving speed of the target.

A door opening system for a merchandise container comprising a plurality of bay doors, the door opening system comprising a wheel in frictional contact with a bay door of the plurality of bay doors; and a motor connected in driving arrangement with the wheel. The motor drives the wheel to rotate and thereby to control a movement of the bay door of the plurality of bay doors between a closed position and an open position.
