Appl. No.:

10/833403

Inventors:

John Scott Erickson - Roscoe IL, US

Assignee:

Atwood Mobile Products, Inc. - Elkhart IN

International Classification:

B60S 9/00

US Classification:

280 6153, 280 6154, 280 6155

Abstract:

An electronic controller for a vehicle leveling system comprises an extend-enable switch, a retract-enable switch, an all-activate switch, and at least one group-activate switch. It is configured to generate an all-extend electronic signal upon coordinated actuation of the extend-enable switch and the all-activate switch, an all-retract electronic signal upon coordinated actuation of the retract-enable switch and the all-activate switch, a group-extend electronic signal upon coordinated actuation of the extend-enable switch and the group-activate switch, and a group-retract electronic signal upon coordinated actuation of the retract-enable switch and the group-activate switch. Vehicle leveling systems having the electronic controller further include a plurality of jacks operably controlled by the electronic controller and a power system.

International Classification:

E04B 1343
B60P 334

US Classification:

52 67

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.
