Abstract
The cathode ray tube assembly of a visual display unit is suspended over the static base in a cradle, the suspension pivots being as close as possible to the center of gravity of the moving section. Attached to the underside of the cradle is a bracket with forked arms. The forks engage with a spindle carrying a pair of friction pads and a helical compression spring. The spindle runs in a curved slot in a bracket attached to the static base. The friction pads are situated one on each side of the bracket and are maintained in intimate contact with it by the helical spring generating a friction force. Thus a force of sufficient magnitude applied to the moving part of the visual display unit will overcome the friction force and permit it to move, although normally the friction force will hold it in the required position.
