Abstract
Abstract A supporting base for controlling height, swivel and inclination of display means such as monitor, television and computer terminal device. The invention is characterized by comprising: first knuckle means N1 in which bosses 4a, 4a of arm 3 are rotatably fixed to bosses 2a, 2a formed at rear end portion of base 1 respectively, and second knuckle means N 2 in which bosses 2b, 2b formed at top end of said arm 3 respectively, said first knuckle means N1 and second knuckle means N2 are coupled with tapered pins of knobs at both ends of screw bar, and tapered bushings urged by compression coil springs are inserted to circumference of said tapered pins whereby closely contacting with surface to tapered holes, simultaneously being provided resiliently by torsion springs, respectively. According to the invention, display means such as monitor or computer terminal can be easily fixed any height, inclining angle and swiveling angle to meet easy viewing by user.
