A mobile modular dwelling system comprising a floor; a front semicircular sub-assembly secured to the floor, the front semicircular sub-assembly including a pane arrangement; and a rear polygonal sub-assembly also secured to the floor and to the front semicircular sub-assembly. In combination, the front and rear sub-assemblies provide a shelter in the face of prevailing wind and rain, regardless of the direction from which weather may originate, while offering an interior designer a wider latitude of furniture choices than does a semicircular footprint alone.

An on-board toilet cubicle for an aircraft, including a front long side and a rear long side; a front short side and a rear short side, which are each connected at one end to the front long side and at their other end to the rear long side, the long sides and the short sides enclosing an interior of the on board toilet cubicle, and the front and the rear long sides each being wider than the front and the rear short sides; a toilet unit with a toilet opening; and an L-shaped door for accessing the on-board toilet cubicle, the L-shaped door having one door leg in the front long side and one door leg in the front short side, the toilet unit arranged adjacent to the rear long side, and the door leg in the front long side being wider than the door leg in the front short side.

A dual-occupancy aircraft minisuite incorporating a modular multiple-egress door assembly is disclosed. In embodiments, the dual-occupancy minisuite can accommodate two passengers in enhanced privacy. Access to (and egress from) the minisuite is through the modular multiple-egress door assembly, which provides forward and rear (relative to the egress gap between) sets of outer, intermediate, and inner doors. The outer doors translate laterally along rails in the intermediate doors, and the intermediate doors likewise translate laterally along rails in the inner doors, to open the minisuite for passenger access or direct view (or to close the minisuite for enhanced privacy). The forward and rear sets of doors are proportioned such that when any forward or rear translating door is jammed in a closed position, the remaining egress gap is of sufficient width to provide a distinct and independent emergency egress path for each occupying passenger of at least minimum required width.

A retractable curved door assembly includes a spring-loaded roller assembly having a reel structure configured to rotate about an axis of rotation thereof, a rail extending away from the spring-loaded roller assembly in a direction perpendicular to the axis of rotation of the reel structure with at least a portion of the rail curving about an axis arranged parallel to the axis of rotation of the reel structure, a door end structure slidably engaging the rail, a flexible screen coupled to the reel structure and to the door end structure, and a tension element coupled to the reel structure and the door end structure. A greater tensile force is applied to the tension element than to the flexible screen when the door end structure is slid along the rail in a direction away from the spring-loaded roller assembly to prevent buckling of the flexible screen.

A door assembly for a restroom stall having first and second opposed side walls and a front opening includes first and second housings defining first and second inner cavities and configured to be mounted on the first and second side walls, first and second doors moveably mounted on the first and second housings, each having opposed inner and outer surfaces that are curved and being moveable along an arcing path between an open position and a closed position. In the open position, the door is retracted within the respective housing and at least partially received in the respective inner cavity, and in the closed position, the door is extended outward of the respective housing relative to the open position. In the closed positions, the first and second doors combine to obstruct the front opening, and in the open positions, the first and second doors permit passage through the front opening.

A privacy enclosure that includes a floor plate, a ceiling assembly, and a sidewall that collectively define an interior cavity. The sidewall may have a laminate structure. The floor plate has a bottom surface and a top surface each with channels therein. The ceiling assembly includes a ceiling plate having a bottom surface with a channel therein. Portions of the sidewall may be positioned within the channel in the ceiling plate and the channel in the top surface of the floor plate. A door may be coupled to the ceiling assembly and to the floor plate. Specifically, the ceiling assembly may include a track member having a track therein and a follower member of the door may ride along the track to alter the door between open and closed states. A bracket member coupled to the door may slide within the channel in the bottom surface of the floor plate.

A traffic door includes a door body having at least one edge and opposed faces, and an edge trim including an inner surface and an outer surface and attached to the door body to cover at least a portion of the at least one edge. The inner surface of the edge trim includes a cavity that receives the at least one edge of the door body therein and the edge trim is secured to the door body through a friction fit between the cavity and the door body. The edge trim includes reinforcement regions adjacent the cavity to increase strength in this region, and void regions away from the cavity to minimizing weight and material usage. A method of assembling a traffic door having edge trim is also disclosed.

Provided is a tower of a wind turbine, having a hollow inner space and a door for opening and closing an aperture into the inner space, wherein the door is a sliding door, which is slidingly arranged on a tower aperture member attached to the tower, and which sliding door is at least partially sealed by a seal to the tower aperture member at least when the door is in the closed position.
