Abstract: In one embodiment, the present invention provides a slide-out system comprising an inner rail that slides into and out of an inner rail. The inner rail is supported within the outer rail by a single support roller and a retaining slide, while a rail gear drives a gear rack on the inner rail to cause extension or retraction. This arrangement allows the rails of the slide-out system to be narrower than those used in many popular flush-floor slide-out systems in use today.

Abstract: An improved RV lift mechanism according to the present invention. In one embodiment, the lift functions by way of an elongated, rotatably mounted acme screw. A bracket slides parallel to the acme screw, securing to an acme screw and an object to be lifted. The acme nut is threaded onto the acme screw and further held from rotation by the bracket. Thus, as the acme screw turns, it presses against the bracket, lifting or lowering both it and its payload.

Abstract: The present invention provides a slide-out room synchronizing mechanism. In one preferred embodiment according to the present invention, the slide-out room synchronizer includes upper and lower timing belts fixed to the side of the slide-out room. Each belt is coupled to a synchronizing belt within the vehicle by a set of connecting gears. As the bottom of the slide-out room moves, the force is transferred through the gears and synchronizing belt to the top upper timing belts. In this respect, the movement of the top of the slide-out room is synchronized to the bottom, providing synchronized extension or retraction at equal or varying speeds.

Abstract: The present invention relates to a vehicle having a fixed room and a slide-out room which extends and retracts relative to the fixed room. The fixed room includes a floor section, sidewall sections, and a roof section, and the slide-out room includes a floor section, sidewall sections, and a roof section. A slide-out extension mechanism extends and retracts the slide-out room in a cantilevered manner. In a fully retracted position, the roof section and two of the sidewall sections of the slide-out room are typically concealed from exterior view, and a third sidewall section of the slide-out room forms a portion of the sidewall section of the fixed room. Furthermore, the floor section of the slide-out room is flush with the floor section of the fixed room, and proximal ends of the sidewall sections of the slide-out room are flush with an inner surface of one of the sidewall sections of the fixed room when the slide-out room is fully extended.

Abstract: The present invention provides a slide-out mechanism that adjusts the elevation of a slide-out room relative to the main body of a vehicle. In one preferred embodiment, the slide-out mechanisms includes an acme screw elevator on a telescoping support arm below the slide-out room. As the slide-out room extends or retracts, the acme screw elevator increases or decreases the height of the slide-out room so as to allow full retraction within the vehicle body and complete level extension.

Abstract: In one embodiment, the present invention provides an upper locking device for a slide-out room which ensures a substantially tight seal is created at the upper portion of the slide-out room.

Abstract: In a preferred embodiment, the present invention provides a vehicle mounting bracket having an adjustable linkage mounting portion. The mounting bracket is fixed to the vehicle and the linkage system, while adjustment bolts on the mounting bracket allow the user to adjust the vertical height of linkage relative to the vehicle. Scalloped adjustment joints of the linkage allow a user to modify the joint angle while effectively increasing or decreasing the length of the linkage members.

Abstract: A slide-out mechanism is provided that adjusts the elevation of a slide-out room relative to the main body of a vehicle. In one preferred embodiment, the slide-out mechanisms includes a tube roller mounted near the edge of the floor to slide vertically. The top end of the tube roller contacts the floor of the slide-out room while the bottom of the tube roller rolls along an extending arm. The extending arm includes a groove which allows the tube roller to reduce its vertical position when the slide-out is fully extended, causing the proximal end of the slide-out to therefore reduce in height.

Abstract: A motor and brake assembly having a disengaging mechanism for use with RV's are disclosed. The assembly includes a motor and a disengaging mechanism that is mounted thereon. The disengaging mechanism includes a motor mount comprised of a cylindrical piece with a plurality of holes disposed on the periphery of an outer flange of the cylindrical piece. The cylindrical piece extends over the barrel of the motor and is secured to the barrel with a plurality of screws. Through manipulation of the cylindrical piece, the user can selectively engage or disengage the brake from the motor.

Abstract: The slide-out mechanisms described herein are generally composed of two components. More specifically, the slide-out mechanism includes at least one elongated member, also referred to as a ram, which is coupled to the floor of a movable room. This elongated member moves with the extendable portion of a movable room. Additionally, the slide-out mechanism includes a base that is coupled to the coach floor and contains a motive device for extending and retracting the movable room accessible from the inside of the slide-out room. According to various embodiments disclosed herein, the motive device may be a hydraulic, pneumatic, or electrical motor. Alternatively, the motive force may be a crank that may be manually actuated to extend and retract the slideout room.

Abstract: Apparatus for selectively extending and withdrawing a trailer slide-out portion includes first and second rails, each slidably supported in a channel mounted underneath the trailer body. The outer ends of the rails are attached to the underside of the slide-out portion. A sheave driven by a reversible motor is mounted between the channels. First and second cables are wrapped around the sheave, the first cable having its ends attached to the first rail, and the second cable having its ends attached to the second rail. A pulley assembly supports each of the cables as it passes from the sheave to its respective rail. The cables, in conjunction with the pulley assemblies, translate the rotation of the sheave into longitudinal motion of the rails through the channels. Thus, sheave rotation in a first direction causes the cables to pull the rails outwardly, extending the slide-out, while sheave rotation in the opposite direction causes the cables to pull the rails inwardly, withdrawing the slide-out.
