Abstract
A low-cost, compact room slideout assembly is provided for driving a sliding element, such as a floor, and comprises at least one motor having a motor output pinion rotatable about a first axis, a drive screw operatively connected to the motor output and rotatable about the first axis, and a driving member, such an elongate ram adapted to be attached to the sliding element. The ram travels along the first axis between extended and retracted positions in response to rotation of the motor output shaft. Preferably operatively connected between the motor output shaft and the drive screw is a speed reducing gearbox with an output shaft rotatable about the first axis, and a 90 degree gearbox operatively connected to the drive screw and rotatable about the first axis. The 90 degree gearbox preferably also has a second output member which is rotatable about a second axis perpendicular to the first axis. The 90 degree gearbox can comprise a series of bevel gears. In certain preferred embodiments a pair of screws and a pair of corresponding rams may be employed, with a cross shaft connecting the first 90 degree gearbox to a second 90 degree gearbox.
