Abstract: A tilting, swiveling, locking base apparatus tilts, swivels and locks to a computer monitor. The base apparatus comprises a tiltball unit including a slot opening which has a key opening portion, a recessed ledge disposed about the slot opening, and a locking rib disposed on the recessed ledge adjacent the key opening portion. The base apparatus further comprises a support unit having support points lying in a plane and including a shaft extending in a direction substantially perpendicular from the plane to an outer end, teeth on the outer end of the shaft configured to fit through the slot opening only in the key opening portion, a locking rim configured to slideably engage the recessed ledge, and an elastic locking snap formed to be deflected by the locking rib when the teeth are inserted into the key opening and to rebound when the shaft is displaced in the slot from the rib. The base apparatus uses a special tool to deflect the locking snap for detaching the tiltball unit from the support unit.
