Abstract
An extension arm has an inner end mounted to a base plate for rotation about a first vertical axis, and an outer end supporting a head assembly. The head assembly has a lower disc fixed to the arm and an upper disc mounted to the lower disc for rotation about a second vertical axis. A first clevis is secured to the upper disc, and includes a first clevis pin passing through the lower end of a connection arm about a first horizontal axis. Adjustable locking means are provided in the first clevis pin, to interlock the first clevis with the connection arm in a selected rotational position about the first horizontal axis. The upper end of the connection arm is secured to a second clevis with a second clevis pin about a second horizontal axis. The second clevis is mounted to a monitor plate which supports the video monitor.
