Abstract
The present invention is a compound motorized lift device facilitating the uninterrupted and nearly noiseless movement of a low-profile television. The invention is comprised of a base unit, an intermediate unit, and a support unit slidably disposed in a telescoping fashion in the described order. A pair of linearly extensible slides are fastened between base and intermediate units and between intermediate and support units. The intermediate unit is extended and retracted with respect to the base unit in a linear fashion via a motor driven screw. The support unit is extended and retracted in a linear fashion via a cable-pulley arrangement that couples motion by the intermediate unit in a likewise direction to the support unit.
