The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.

Movement system for a closure structure with folding movement, comprising a transmission hinge which connects a first panel to a second panel of the closure structure. The transmission hinge has a first wing fixed to the first panel, a movement lever hinged to the first wing around a first axis, and a second wing which is hinged to the movement lever around a second axis and is fixed to the second panel. The movement system comprises a transmission mechanism which, following the rotation of the first panel, drives the movement lever to rotate around the first axis. The transmission hinge comprises a gear connecting the first wing to the second wing so that, following the rotation of the movement lever, the second wing is actuated by such gear to rotate around the second axis in order to make the second panel rotate with respect to the first panel.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

A motor control system for a folding partition includes a data storage device and processing circuitry. The data storage device is configured to store a normal threshold profile to serve as a threshold for a measured current supplied to a motor to detect abnormal operation of the motor. The motor is configured to drive motion of the folding partition. The processing circuitry is operably coupled to the data storage device. The processing circuitry is configured to generate an adjusted threshold profile to serve as a threshold for the measured current supplied to the motor while moving the folding partition during a transition from an abnormal operational mode to the normal operational mode. The adjusted threshold profile is used for detecting additional abnormal operation of the motor. The processing circuitry is configured to generate the adjusted threshold profile by adjusting at least a portion of the normal threshold profile.

An expandable lavatory and an aircraft cabin configuration including the same. First, second and third walls form the lavatory interior and the third wall is repositionable to expand the lavatory interior footprint to accommodate a wheelchair. The third wall carries a door deployable when the third wall is in the expanded configuration such that the wheelchair can access the lavatory interior via an exit pathway. A first door positioned in the second wall provides access to the lavatory interior via a longitudinal aisle. In some embodiments, a wheelchair securement area is positioned longitudinally aligned with the second door, when the second door is deployed, such that wheelchair access to the lavatory is provided through second door when the lavatory is in the expanded configuration.

Disclosed is an automatic released foldable door having a two-way door structure, which foldable door comprises a first closing door device (11) and a second closing door device (13), wherein a first door leaf (2) is connected to one side of the first closing door device (11), the second closing door device has one side connected to the first door leaf (2) and the other side thereof connected to a second door leaf (6), the second door leaf (6) is a door-in-door and a two-way door structure; and the foldable door further comprises a plurality of fixing devices (3, 31, 7) and at least one hinge (4). The foldable door has a relatively small turning radius and can be folded for receiving, and the door-in-door can be rotated in different directions.

A new door system and related technology for a passenger carrying rail vehicle, such as a President's Conference Committee (PCC) streetcar rail vehicle, and a method for retrofitting a rail vehicle door system with the new door system. In some embodiments, the new door system includes an electro-mechanical angle drive motor, a solid door control pivot rod, a door leaf panel clamp that is permanently connected to the solid door control pivot rod, a lever arm that includes a positive locking device and that is coupled to the solid door control pivot rod, and a connecting rod that is attached to the electro-mechanical angle drive motor and to the lever arm to enable the connecting rod to impart motion generated by the electro-mechanical angle drive motor to the lever arm.

A bi-fold door stop controls movement and travel of lead and pivot doors in a set of vertically hung bi-fold doors. The bi-fold door stop has at least two non-parallel surfaces that each may act upon one or both of the lead and pivot door stiles to limit movement in two directions. Movement transverse to the track longitudinal axis is limited when the bi-fold door is either fully open or fully closed, while parallel movement is controlled by limiting the extent that the bi-fold door may be opened. At least two non-parallel surfaces are provided that each may act upon one or more of the lead and pivot door stiles, while an additional surface may act upon the face of the pivot door. The bi-fold door stop may be fabricated as a single part using common molding operations, and acts directly on the door panels, thereby preserving bi-fold door hardware.
