A stand (10) has a base (20) with upstanding portion (20) stationary therewith. The base (20) can rotate. A post (30) is attached to upstanding portion (20) by carriage (38) and knob (26.) When knob (26) is in an unlocked position the carriage (38) slides in channel (44) of post (30). When knob (26) is in a locked position the post (30) remains stationary with respect to upstanding means (22). Carriage (38) is connected to post (30) by a constant force arrangement which can include coil spring(s), elastic cord(s) or a gas spring to provide balanced damped movement of post (30) when knob (26) is unlocked. At top end of post (30), a fixture (34), pivotable on adjustable pivot bolt (35), can hold a flat panel display on arms (99). Fixture (34) can be rotated to provide a 15-20mm height adjustment. Cables from the computer to the display screen may be contained in a plurality of channels or conduits contained in the vertical post. The longitudinal axis of the post may be inclined forward by 7{ in order to move the centre of gravity of the stand. A brake means may be provided to lock the moveable sections of the vertical post in a desired position. |
