A bi-directional door for the elderly and handicapped which comprises a support assembly mounted to a floor, a swing gate pivotally mounted about a support shaft in the support assembly, and a controller assembly located within the support assembly. A first bevel gear at the base of the swing gate is positioned for rotation about the support shaft. A second bevel gear, which is controlled by the controller assembly, is coupled to the first bevel gear at a 90 degree angle. Accordingly, when the swing gate is opened and released, the controller assembly controls the rotation of the first and second bevel gears such that the swing gate returns back to a home position at a predetermined rate. In addition, the support assembly includes various ways for adjusting and fine tuning the angular position of the bi-directional door in the support assembly.
