Abstract: A device for lifting and lowering objects and electronic devices includes an elevating mechanism that elevates a first sliding frame and a second sliding frame. The first and second sliding frames move independently inside of a mounting frame. A linear actuator drives the first sliding frame and causes the first sliding frame to rise and fall. A belt and pulley configuration transfers an elevating force from the first sliding frame to the second sliding frame. The second or subsequent sliding frame is elevated to place the display or object at a desired height and may be retracted to conceal the display or object in a cabinet, or the like.

Abstract: A device for lifting and lowering visual displays, such as television sets, video monitors, plasma displays, pieces of art, or the like. The elevating device includes an elevating mechanism that elevates a first sliding frame and a second sliding frame. The first and second sliding frames move independently inside of a mounting frame. A motor rotates a pair of vertical threaded rods to drive the first sliding frame and cause the first sliding frame to rise and fall. A belt and pulley configuration transfers an elevating force from the first sliding frame to the second sliding frame. The second sliding frame includes supporting bars and is elevated to place the display at a desired height and is retracted to conceal the display in a cabinet, or the like.

Abstract: Two adjustable display-supporting bars, which are attached to the front of the elevating apparatus, support visual display such as plasma television. An elevating mechanism elevates or lowers two supporting bars with attached display, with use of motor. The motor rotates one or two vertical threaded rods.
