Abstract:
A guide rail device is provided for hanging doors. The device is effective to accurately guide the hanging door without deviation, yet does not project up from the floor when the doors are open, as is the case with a guide rail or a groove-rail mounted on the floor surface. When the hanging doors are open, guides of the device are retracted into a guide rail in the floor surface and thus do not project from the floor surface. When the hanging doors are closed, the guides are projected from the floor surface and are fitted in a long groove from in a bottom end surface of the hanging doors, such that the hanging doors are prevented from deviating while being moved.
