On a plane, it is not possible to walk along the aisle during meal service as the food trolley occupies almost the entire width of the narrow passage. Passengers must wait until the meal distribution comes to an end in order to access the lavatory.
Parallel Dining Car divides the typical trolley into two slim parts that can be used together or split apart. They are connected and disconnected via the manipulation of a magnetic handle. When a passenger needs to pass by, the attendants press a button on the handle. A magnetic ring connecting the handle and the body of the trolley will automatically disengage, thus separating the trolley into two parts. These can be placed one behind the other to allow the passenger to pass. The width of each half-trolley accommodates a row of meal boxes, so the separation will cause no disturbance to regular distribution.
