Adjustable support for a display monitor

A support for an object of appreciable weight (e.g., for a CRT display) comprises a mount 10 which, in use is located at a reference height. A crank 20 extends from this mount. A boom 12 is pivotally mounted on the mount and extends therefrom to and carries means (not shown) for attaching the intended object which is to be located at an adjustable height with respect to the reference height. A lift lever 26 and a gas strut 30 are carried wholly by the boom. A lift rod 36 is mounted between a position on the crank remote from the mount/boom axis 18 and the lift lever, the latter being pivotally mounted in the boom. The lift rod and the gas strut are connected to the lift lever, but with the strut at a greater separation from the lever's pivot than the rod. The gas strut engages the boom and counteracts the effects of gravity on the loaded support. In addition to the lift mechanism, the support can also incorporate a parallel motion and a tilt mechanism.

Support apparatus

An adjustable support for a display monitor includes a turntable to allow swivelling and carrying a pair of support tubes on which is mounted a slidable support beam. A carrier having cylindrical bearing surfaces co-operates with skid-pads on the support beam. By sliding the carrier with respect to the support beam the angle of the carrier and hence the angle of the display screen can be varied. A non-magnetic gas strut located in one of the support tubes compensates for the weight of the monitor/carrier assembly. The force exerted by the gas strut is shared between the support tubes by means of a pair of coupled rack and pinions which also allow convenient height adjustment of the support beam, carrier and display monitor.
