Abstract: A truck bed extension device (10) for use with a truck (12) having a cargo bed structure, wherein the device (10) allows for carrying items which extend beyond or overhang the bed structure. The device (10) comprises a deck (24); a support structure (26); and a signaling system (28). The deck (24) is horizontally adjustable relative to the bed structure so as to allow for achieving a desired spacing therebetween. The deck (24) is also vertically offset when unloaded so as to be substantially flush when loaded. Because the device (10) or the load carried thereon may obstruct viewing of the truck's existing brake and turn signals, the signaling system (28) repeats these signals where they are more visible. A second embodiment of the device (110) provides a hitch structure (170) for coupling the truck with a trailer via the device (110).

Abstract: A slide-out room (12) support system (28) for a recreational vehicle (10) has outer C-shaped rails (34) received at least partially within the thickness of the floor (64) with the slot of the C-shape opening downwardly. A fixed support (30) extends up through the slot and mounts four rollers (38), two on each side, which extend into the space between the top wall (42) of the rail (34) and the flanges (40) so as to support the rail (34) generally horizontal and relieve much of the weight of the slide-out room (12) from being borne by the stationary floor of the recreational vehicle (10). A lead screw (46) that moves longitudinally with the rail (34) drives it in and out, and a rack (60, 70) and pinion (62, 68) system synchronizes the movement of the rails (34) when two or more rails (34) are provided. The lead screw (46), or alternatively the rack (60, 70) and pinion (62, 68) system, may be manually or electrically driven.

Abstract: A recreational vehicle includes a main living area and a slide out room that slides between an extended and retracted position relative to the main living area. At least one extendable support member is mounted within the floor of the main living area, and is connected to the slide out room so that the weight of the slide out room is transferred to the extendable support member as the room slides to the extended position. The extendable support member bends in response to the weight transfer such that the room floor is substantially flush and level with respect to the main living area floor. The extendable support includes an inner support connected to the room and the outer support connected to the vehicle. The shape of the inner support may be such that the end connected to the room drops vertically as the inner support is extended from the outer support.

Abstract: A slide-out room for recreational vehicles, sleeper cabs of trucks, and similar mobile living quarters is supported for movement through an aperture in the side wall of the mobile living quarters by a set of four linkages, two of which are mounted between each side of the slide-out room in the corresponding side of the aperture of the side wall of the unit. When the slide-out room is fully retracted within the mobile living quarters, one of the linkages on each side of the slide-out room is fully extended and the other is fully collapsed. As the slide-out room is moved toward the fully-extended position, the other linkage gradually expands and the one linkage collapses, so in the fully extended, as well as the fully retracted position, the slide-out room is supported and aligned for movement through the aperture in the vehicle slide-out room, and the slide-out room is continuously supported as it travels between the extended and retracted positions.

Abstract: A recreational vehicle having an extendable slide-out controlled by an actuator assembly is provided with a damage avoidance system. The damage avoidance system determines if the slide-out is in an adverse state and, if the adverse state is detected, inhibits the actuator assembly from moving the slide-out. The slide-out is in the adverse state if (a) a collision between the slide-out and a nearby object is imminent, (b) a collision has recently occurred, or (c) a resistive force is acting on the slide-out which substantially inhibits the actuator assembly from moving the slide-out. The damage avoidance system comprises a sensor module for monitoring the state of the slide-out and for providing an override signal to the actuator assembly, wherein the override signal is indicative of the slide-out being in the adverse state.

Abstract: An electronic slide-out room synchronization system is provided to synchronize multiple actuators of a slide-out room so that the slide-out room has accurate alignment during extension or retraction while further providing a proper seal at full extension or retraction. The system comprises two linear actuators such as lead screw mechanisms or hydraulic cylinders in communication with a controller activated by an activation or room switch located inside a recreational vehicle. The linear actuators, when signaled via the controller, move the slide-out room between a retracted position and an extended position. If the controller determines, by receiving signals from a sensor, that one of the linear actuators is moving faster or is extended or retracted further than the other linear actuator, the controller synchronizes the actuators so that they extend and retract in unison.

Abstract: A drive mechanism is shown for transportable living quarters. An outer tube is oriented so that the corresponding inner tube extends downwardly relative to the main living area, lowering the slide-out room back wall and causing the slide-out room to tilt slightly outward in its extended position to compress an inner compressible seal between sealing surfaces on the main living area and the slide-out room inner flange. Similarly, upon retraction, the back wall is raised relative to the main living area, tilting the room in the opposite direction to compress an outer compressible seal between sealing surfaces on the outside of the main living area and the outer flange of the slide-out room. The mechanism may include an adjustment mechanism to adjust the angle of the outer tube for optimal sealing. The mechanism may also be used in conjunction with a wear bar attached to the edge of the main living area floor to increase the tilt applied to the slide-out room for added pressure on the compressible seals.

Abstract: A recreational vehicle includes a main living area and a slide out room that slides between an extended and retracted position relative to the main living area. At least one extendable support member is mounted within the floor of the main living area, and is connected to the slide out room so that the weight of the slide out room is transferred to the extendable support member as the room slides to the extended position. The extendable support member bends in response to the weight transfer such that the room floor is substantially flush and level with respect to the main living area floor. The extendable support includes an inner support connected to the room and the outer support connected to the vehicle. The shape of the inner support may be such that the end connected to the room drops vertically as the inner support is extended from the outer support.

Abstract: Transportable living quarters includes a main frame supporting a main living area and a slide-out room that slides between an extended and retracted position relative to the main living area. The actuation mechanism for extending and retracting the slide-out room includes a curved slider arm that causes the slide-out room to tilt slightly when moving into the fully extended or retracted positions. Upon extension, the slide-out room tilts outwardly to compress an inner compressible seal between sealing surfaces on the main living area and the slide-out room inner flange. Upon retraction, the slide-out room tilts in the opposite direction to compress an outer compressible seal between sealing surfaces on the outside of the main living area and the outer flange of the slide-out room. This tilting of the room results in a tighter seal at the top of the slide-out room that better isolates the living area from the outside elements.
