Abstract: A monitor stand provides a self-aligning and self-orientating swivel lock mechanism for desktop monitors so the monitor stand can be easily locked at the center position to provide better user experience and easier manufacturing. A base of a monitor stand has a die cast plate and a swivel plate attached thereto to allow the monitor stand to rotate from the center position. A lock plunger of a swivel lock mechanism travels along a circular guided cam profile on the swivel plate when the swivel lock mechanism is engaged and the monitor stand is rotated. When the swivel lock mechanism rotates to the center position, a recessed portion of the circular guided cam profile receives the lock plunger of the swivel lock mechanism to thereby lock the swivel plate at the center position. The user engages/disengages the swivel lock mechanism by pushing an engagement button that extends from the base.
