ABSTRACT:
The base support of a display device provided comprises a base plate and a brake device. The base plate has a plurality of cavities with a depth and corresponding retainer plates. Within each cavity a rolling ball with a diameter is received. Each retainer plate is attached to the base plate for retaining the rolling ball within the cavity and has a circular opening smaller than the diameter of the rolling ball. The diameter of the rolling ball is larger than the depth of the cavity such that a small portion of the rolling ball is exposed to the outside of the cavity through the circular opening. The rolling ball comes into a first rolling contact with a table surface. The base plate also has a plurality of slots each receiving a roller. The rollers come into a second rolling contact with the table surface. The base plate also has a plurality of slots each receiving a roller. The rollers come into a second rolling contact with the table surface. The brake device is connected to the base plate and is selectively enabled to prohibit the rolling movement of the base support on the table surface.
