Abstract
A swivel base includes a stationary bottom support to be placed on for example a desk and a movable tray movably supported on the fixed bottom support to support thereon for example a monitor. The bottom support has a circular wall having an inclined inner face and the movable tray has a concave member corresponding to and slidably supported on the inclined face. A post located at center of a recess defined by the circular wall with an expanded retaining member fixed thereon. An elongated slot is provided on the concave member and has an widened section to receive the penetration of the retaining member for retaining the post within the slot in a movable manner and to allow the movable tray to rotate about the post. A stop block is provided within the recess defined by the circular wall and a corresponding rib is provided on the underside of the concave member to be contactable with the stop block for limiting the rotation of the movable tray about the post. A slit is formed on the inclined face adjacent to the stop block to define a cantilever type, resilient plate having a free end close to the stop block. The resilient plate is arranged to be contacted and depressed by the rib of the movable tray during mounting the movable tray to the bottom support and to prevent the movable tray from accidently disengaging from the bottom support.
