A transportable folding door includes a folding door body and a door handle bar arranged on a side of the folding door body. A handle is arranged on the door handle bar. The folding door body is made of a flexible polyester material. The door handle bar is formed by splicing a plurality of supporting bars, and a connecting assembly is arranged between two adjacent supporting bars. Connecting holes are separately formed at a connection of the two adjacent connected supporting bars, and the connecting assembly is fixedly connected to the connecting holes of the two adjacent connected supporting bars. The connecting assembly includes a clamping bar with a U-shaped cross section, connecting columns, and a connecting piece. Both ends of the clamping bar are separately provided with receiving holes corresponding to the connecting holes on the two adjacent connected supporting bars.

A retractable bathroom door includes a fixed frame, a mobile frame, a first pull string and a foldable portion. The mobile frame is perpendicular to the upper frame portion of the fixed frame and horizontally moves in a frame range thereof. A frame portion at one side of the mobile frame has a first hollow structure. A first upper pulley and a first lower pulley are respectively disposed at a top end and a bottom end of the first hollow structure. The first pull string has two ends which are wound around the first upper pulley and the first lower pulley in a crossover manner. An upper rail and a lower rail are respectively disposed on the upper frame portion and the lower frame portion of the fixed frame. An upper strip and a lower strip are respectively disposed on the upper rail and the lower rail.

An access device enables controlled or secure communication between different areas of an enclosure, and in the example illustrated in the present application of an aircraft, while providing reduced size. The access device includes a folding door which, when in folded position, allows at least one of said openings to be closed and, when in deployed position, forms a security vestibule with at least one movable shutter allowing said opening created by the deployment of said folding door to be closed. By superimposing the main components of the security vestibule that said components allow to close, the device frees up the adjoining cabin space when the security vestibule is not in use.

A separation and containment system is provided. The separation and containment system can contain natural gasses, e.g., compressed natural gas (CNG) and liquefied natural gas (LNG), within a natural gas vehicle (NGV) service area, and separate the NGV service area from a conventional service area. The separation and containment system utilizes one or more barriers, such as industrial fabric/vinyl materials that meet various regulatory safety standards applicable to NGVs. The separation and containment system is easily constructed, dismantled, and resized/adapted in accordance with desired operating conditions.

A retractable bathroom door includes a fixed frame (1), a mobile frame (2), a first parallel pull string (3) and a foldable portion (4). The mobile frame (2) is perpendicular to the upper frame portion of the fixed frame (1) and horizontally moves in a frame range of the fixed frame (1). A frame portion at one side of the mobile frame (2) has a first hollow structure (13). A first upper pulley (5) and a first lower pulley (6) are respectively disposed at a top end and a bottom end of the first hollow structure (13). The first parallel pull string (3) has two ends which are connected and wound around the first upper pulley (5) and the first lower pulley (6) in a crossover manner. An upper rail and a lower rail are respectively disposed on the upper frame portion and the lower frame portion of the fixed frame (1). An upper rack (9) and a lower rack (10) are respectively disposed on the upper rail and the lower rail. Two ends of the upper rack (9) and the lower rack (10) respectively enter the first hollow structure (13) from a first upper opening (7) and a first lower opening (8) of the first hollow structure (13), and are connected with the first parallel pull string (3). A length of the upper rack (9) disposed on the upper rail is as same as a length of the lower rack (10) disposed on the lower rail. The foldable portion (4) is disposed between two mobile frame portions of the mobile frame. The retractable bathroom door is adapted for small space installation, has strong adaptability and stable moving.
