INTERCHANGEABLE DOOR

An interchangeable door system (IDS) having a central axis and at least two different opening configurations defined by corresponding different locations of the central axis. The system comprises a wall formed with a wall opening having a circumferential rim and a surface pre-formed with at least a first and a second surface-port. The first and second surface-ports are located along the circumferential rim at locations spaced apart from one another along a direction transverse to the central axis. The system further comprises a door having an outer contour corresponding in shape and dimensions to the opening and being adapted for revolving about the central axis, thereby opening and closing the wall opening. The door is pre-formed with at least a first and a second door-port, the door-ports being located along the outer contour at locations corresponding to the locations of the first and second surface-ports. The system also comprises an interchangeable door arrangement (IDA) adapted to provide selective engagement between each door-port and its corresponding surface-port, forming an engaged port-pair whose location defines the location of the central axis, to thereby bring the central axis into a location of the engaged port-pair, so as to allow the door to operate in the different configurations.
