A customizable closure system comprising panels of a pre-selected size and one or more conversion kits for mounting the panels. A room divider conversion kit comprises a hinge for converting the panels into room dividers, and a bypass conversion kit comprises a header for converting the panels into slidable panel doors, such as a closure for a shower area. Other conversion kits include a swing conversion kit and a hanger conversion kit. One embodiment of the panels further comprises a reinforcing system for securely retaining the panes with the panel.

Drive assemblies for partition systems may include a motor and a power transmission mechanism operably coupled to a drive shaft of the motor. The power transmission mechanism may include a first bevel gear rotatable by the drive shaft and a second bevel gear positioned for engagement with the first bevel gear. The second bevel gear may include an axis of rotation oriented at least substantially perpendicular to an axis of rotation of the first bevel gear. A disengagement mechanism may be coupled to at least one of the first bevel gear or the second bevel gear and configured to selectively engage and disengage the first bevel gear and the second bevel gear.

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.

An accordion type folding door system having a plurality of elongated panels hinged together along their longitudinal side edges into a pleated or zig zag arrangement, the folding panels being interconnected by a hinge assembly. The hinge assembly is disposed between and interconnects a pair of adjacent panels, each of the pair of interconnected adjacent panels including a side edge having longitudinal groove and an extension flange, wherein the hinge assembly includes a hinge pin and a plurality of hinge knuckles disposed vertically end-to-end in alternating arrangement on the hinge pin, the hinge knuckle having a tubular central opening for accepting the hinge pin, an outwardly extending tongue for connecting to a corresponding longitudinal groove in an adjacent panel in a tongue and groove connection, and an outwardly flared wedge that extends beyond the extension flanges of the panels, whereby the wedge cooperates with the extension flanges to limit angular folding extension to a maximum desired angle.

A barrier door configured to be mounted in an opening in a cabin area of an aircraft. The barrier door is movable between an open position to allow persons to pass through the opening and a closed position to prevent passengers from moving through the opening. The barrier door is configured to be locked in the closed position.

An aircraft lavatory monument is provided that includes a first lavatory including a first door providing access to the first lavatory from an aisle of an aircraft; a second lavatory proximate the first lavatory, the second lavatory including a second door providing access to the second lavatory from the aisle of the aircraft; and a movable wall disposed between the first lavatory and the second lavatory, the movable wall including a latching mechanism positioned on an exterior edge of the movable wall and accessible from the aisle of the aircraft, where the latching mechanism, responsive to being in a locked position, causes the movable wall to be positioned at a first position separating the first lavatory from the second lavatory and providing privacy therebetween, and where the latching mechanism, responsive to being in an unlocked position, allows the movable wall to collapse thereby forming an enlarged bathroom space.

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.

There are described fully trackless, frameless bi-fold doors for use with conventional bathtubs, showers, or walk-in bathtubs.

A powered folding door or window system includes at least two rigid panels that are linked together by at least one vertical hinge/pivot to fold between a closed state, where the panels extend across an opening, to an open state, where they are retracted to one side of the opening and stacked against each other. The system incorporates a motor and a drive belt mechanism as primary means for driving the panels. The system further includes a powered actuator on one of the panels and a co-operative element on a linked adjoining panel; whereby the powered actuator cooperates with the co-operative element on the linked adjoining panel to move the linked adjoining panel and said one panel about the vertical hinge/pivot linking them; whereby the powered actuator may start the opening of the door or window system and/or complete the closing of the system.

Monitoring systems for automatic doors comprise at least one input device configured for sensing at least one characteristic of at least one operational parameter of an automatic door system, a door system controller coupled to the at least one input device, at least one monitor display comprising a first interface operatively coupled to the door system controller, and at least another interface operatively coupled to the monitor display and configured to be operatively coupled to at least one remote display device. The at least one monitor display is configured to continuously request information representative of the at least one operational parameter characteristic from the door system controller and display the information. Methods of monitoring an automatic door system comprise transmitting data representative of an operational parameter characteristic from an input device to at least one door system controller; sending a description of the operational parameter to a monitor display continuously; and displaying indicia representative of the description of the operational parameter.
