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 system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.

An apparatus for an architectural opening may include a plurality of panels. At least one of the plurality of panels may include a frame including a pair of rails and a pair of stiles secured to the pair of rails at respective interfaces. The frame may define at least one opening. The interfaces may be sealed in a manner allowing a vacuum to be created inside at least a portion of the frame. An inset panel may be secured within the at least one opening. At least portions of the frame may be vacuum insulated. One or more hinges may secure a first panel of the plurality of panels to a second panel of the plurality of panels. The member may be a transparent or translucent window. The apparatus may be a garage door, an entry door, a window, or a storefront.

A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

The present disclosure is generally directed to a gate having a frame that can fold and collapse into a compact profile for purposes of storage and travel. In an embodiment, a gate consistent with the present disclosure includes a plurality of frame members coupled together via hinged couplers. The hinged couplers provide an in-use configuration whereby the frame members occupy substantially the same plane and form a picture-frame/rectangular shape. Preferably, a foldable material such as mesh at least partially surrounds each frame member and extends between the frame members to form a sidewall. The hinged couplers include at least a first hinged coupler configured to allow for out-of-plane rotation about a first axis to fold the frame members relative to each other in a clamshell fashion, and at least a second hinged coupler to allow for in-plane rotation about a second axis to collapse the frame members.

A folding system has a bottom guide rail and a top guide rail. A first folding wing and a second folding wing are supported movably in the bottom guide rail and the top guide rail, respectively. The first folding wing has a vertically extending frame section. A lock fitting is arranged in the vertically extending frame section of the first folding wing and has a vertically slidably supported locking pin. A locking gear is connected to the locking pin and can move the locking pin into and out of one of the bottom and top guide rails. A reinforcement pin is arranged parallel to the locking pin in the vertically extending frame section of the first folding wing. The locking pin and the reinforcement pin are connected to each other such that the reinforcement pin is entrained parallel to the locking pin when the locking gear is actuated.

An articulating bracket for a hanging door. The articulating bracket is a two-part structure having a top piece and a bottom piece rotatably coupled together. The bottom piece attaches to a door, and the top piece extends upward from the bottom piece, with a roller wheel attached to the top piece and adapted to roll along a rail mounted above the door. The articulating bracket is particularly advantageous for a pair of doors that are coupled together at their proximal edges. With a first articulating bracket attached at one extreme top position of the first door and a second articulating bracket at the other extreme top position of the second door, one of the articulating brackets is affixed to a supporting structure and the other is free to move with the roller wheel along the rail. As the roller wheel is moved, both of the brackets rotate to follow the outward rotation of the doors.

Galley trolley compartment doors that replace traditional trolley retainer latches used to secure trolleys when positioned in galley compartments. The galley trolley compartment doors are designed with engaging arms that help secure the trolleys in place under required loads. Some embodiments of the galley trolley compartment doors are designed with thicknesses that can help improve cooling of the trolley compartment.

A motor control system comprises a motor control circuit, a non-transitory storage medium and a processing circuitry. The storage medium is configured to store a current threshold profile that is indicative of a current requirement of the motor control circuit for an operational cycle of a motor. The processing circuitry is configured to adjust the stored current threshold profile based on a change to the operational cycle of the motor (e.g., from standard to non-standard).
