Abstract: A platform supports a visual display such as a large flat television monitor. An elevating mechanism behind or in front of the display elevates or lowers the platform and the display with a motor. The motor rotates a pair of vertical threaded rods in synchrony. Threaded nuts on the rods raise and lower as the rods rotate. A support bushing sliding on a vertical smooth rod adjacent each threaded rod is connected to the nut to rise and fall with it. The platform is connected at each end to one of the support bushings and extends away from the mechanism to cause the platform and the display thereon to elevate and lower with the nuts under the control of the motor. An alternative embodiment causes the platform to elevate to a height far above the height of the retracted apparatus for concealment in a shorter cabinet.
