Abstract
The actuator uses reinforced polyurethane timing belts as a flexible rack member mounted to the slide-out room and a pinion assembly mounted at the top and bottom of the slide-out opening of the main compartment. A pair of timing belts are mounted at the corners of the slide-out room top and floor, each running longitudinally to the direction of the slide-out movement. Each pinion block includes a pinion and two idle rollers. The timing belts pass through the drive block being trained around the pinion between two idle rollers in a serpentine fashion. A reversible electric motor, which is operatively connected to all four pinion blocks, simultaneously turns the pinions to propel the timing belts through the pinion blocks thereby extending and retracting the slide-out room through the slide-out opening.
