Abstract: The invention provides a vertical lift mechanism (10) for a bunk bed within a recreational vehicle. The mechanism includes a lateral support assembly (14) that travels up and down in an upright frame assembly (34). The lifting force is provided by a drive unit (12) mounted to the support assembly (14) that winds and unwinds a flexible member (18) through a guide arrangement (68, 70, 72, 74, 76, 78, 80, 82) mounted to the support assembly (14). The flexible member (18) is preferably an assembly of cables, more preferably four primary cables (52, 54, 56, 58) each having one end attached to the ceiling of the vehicle and their opposite ends coupled together and linked to a leader cable (50) which is wound about the drive spindle (44). The primary cables (52, 54, 56, 58) travel around the guides (68, 70, 72, 74, 76, 78, 80, 82), which can be an arrangement of single and double sheaves or pulleys, to translate the winding force to vertical forces that raise or lower the support assembly (14).

Abstract: A cable operated slide-out mechanism for a recreational vehicle has a linear actuator mounted in a fixed channel alongside the room or compartment and an end of each cable is fixed to the channel. Four cables are provided on each side of the slide-out, with two of the cables on each side fixed to the frame on the top and going to the outside of the slide-out, on the top and bottom, and the other two cables fixed to the frame on the bottom and going to the inside of the room on the top and bottom. Pulleys are provided at each end of the actuator rod to pull on the cables so as to move the room such that the room movement is double the stroke of the actuator.

Abstract: An in-vehicle lift mechanism has a heavy duty drive assembly suitable for lifting heavy loads, such as all terrain vehicles, motorcycles and other motorized equipment and vehicles. The lift mechanism has four corner posts that are fixed to the vehicle and guide a support platform. The drive assembly includes a motor that drives a screw to engage a nut secured to a movable pulley carriage. As the screw turns, the pulley carriage translates relative the platform to either let out or take up cabling allowing the platform to be raised or lowered. The mechanism uses multiple cables, the ends of which are secured in fixed positions, one end being fixed relative to the platform and one fixed relative to the vehicle. A plurality of stationary position pulleys route the cables between the platform and the posts.

Abstract: A leveling leg assembly adapted for mounting to a vehicle includes an outer member and an inner member telescoped slidably into the outer member. The inner member has a first end extending beyond the outer member. The inner member is telescopically driven out of the outer member from a retracted position toward an extended position. A first bracket is fixed to the outer member, and a second bracket is fixable to the vehicle, wherein one of the first and second brackets has a plurality of holes formed therethrough, and the other of the first and second brackets has at least one hole formed therethrough that is aligned with at least one of the plurality of holes to fix the first bracket relative to the second bracket at a desired height relative to the vehicle.

Abstract: A gear operated pivoting travel lock secures a slide-out section of a vehicle in a retracted position. The travel lock includes a gear box, containing two mating worm gears, that mounts to a wall of the slide-out section. The drive gear is mounted at the end of an operating member and the driven gear is mounted to an axle. Two pivot arms are mounted at the ends of the axle. Turning the operating member, preferably by a handle member, rotates the drive gear to mesh with the driven gear. As the driven gear rotates, the pivot arms swing out from a collapsed position to an engaged position. When the slide-out section is retracted within the vehicle, a pressure pad at the end of the pivot arms clamps against an interior surface of the vehicle wall. When the travel lock is collapsed the slide-out section can be moved between the retracted and extended positions.
