    Abstract: An electrically releasable hold-open device for use with a door closing mechanism employing a latch device that engages an element reciprocating in a trackway. The latch device has a pair of arms that are controlled by a solenoid. The solenoid, when energized, operates a wedge to spread the arms. The arms in spread position perform a latching function in cooperation with a cavity on the reciprocating element. The solenoid when deenergized deactivates the latching function.

    Abstract: A door with electro-mechanical operating means has a height substantially equal to half the height of the opening to be closed. Two elbowed guide rails are situated on either side of the opening and made fast with the door frame, and two pairs of guide devices are provided on either side and quite close to the lower and upper extremities of the lower panel. A winding device constituted by a winding drum is driven by a motor and reduction gearing or a hydraulic or pneumatic element, and a strap or linkage connects the lower extremity of the lower panel, on each side of the opening, to the winding element. A device for couples the two panels of the door, and the operating means are controlled by a tumbler change-over switch.

    Abstract: An electrically releasable hold-open device for use with a door closing mechanism employing a latch device that is engaged by an element reciprocating in a trackway. The element when moved to hold-open position shifts the latch device up an inclined ramp to a location in which the latch device is releasably held by retaining means. The retaining means is controlled by an electrically energized solenoid so that it is released in the event of an emergency.
