Patent number: 6886875Abstract: A securing mechanism for use with a recreational vehicle (RV) slide out assembly. The securing mechanism structurally interconnects the slide out assembly to the RV when the slide out assembly is in a retracted position and when it is in an extended position. Specifically, loads in the RV induced from the road, from passengers, from equipment, and other various sources are distributed through the slide out assembly. Advantageously, flexure of the RV walls around the slide out opening is reduced. As a result, walls and their fixtures are less likely to be damaged due to flexure, seals between the RV walls and the slide out are more likely to stay intact, and the size of slide outs can be increased without compromising the structural integrity of the RV.Type: GrantFiled: September 16, 2003Date of Patent: May 3, 2005Assignee: Alfa Leisure, Inc.Inventor: Johnnie R.

Patent number: 6807735Abstract: A method of fabricating a motorhome, wherein the motorhome comprises a chassis, a vehicle frame, and a coach body. In one embodiment, the method begins by prefabricating the frame by joining a plurality of parallel elongate members with cross-tie members. The frame is prefabricated separate from the chassis, and in one embodiment, the frame is prefabricated upside down such that the underside of the frame is accessible for attachment of a plurality of bulkheads. Then, the frame is rotated upright and positioned atop the chassis. In one embodiment, the rails of the chassis lie inside a channel defined by the plurality of bulkheads. Next, additional bulkheads are joined to the frame and chassis to further interconnect the frame and chassis. Preferably, the additional bulkheads comprise an opening such that the additional bulkheads can surround the chassis on all sides. Finally, the coach body is assembled on the frame.Type: GrantFiled: September 26, 2001Date of Patent: October 26, 2004Assignee: Alfa Leisure, Inc.Inventor: Johnnie Crean

Patent number: 6793260Abstract: A recreational vehicle (RV) with a central actuator that controls locking and unlocking of a plurality of access doors. Each of the access doors has a locking member that is interconnected to the central actuator. Thus, the central actuator may be configured to lock or unlock selected group of doors simultaneously. The central actuator is located inside the RV, and controlling input to the central actuator may be from a remote transmitter, or by direct manipulation of the central actuator. The locking members and the central actuator may be linked mechanically, electromagnetically, hydraulically, pneumatically, or in any number of ways. The central actuator advantageously permits an RV user to lock or unlock groups or all of the access doors simultaneously while inside the RV, or by using the remote transmitter.Type: GrantFiled: July 24, 2002Date of Patent: September 21, 2004Assignee: Alfa Leisure, Inc.Inventor: Johnnie R.

Patent number: 6776451Abstract: A unitized heating, ventilation, and air conditioning (HVAC) system ventilates and regulates the air temperature inside a motorhome. Air is drawn from inside the motorhome and is directed to a furnace and an air conditioning unit via a common air return. A filter is positioned within the common return. The HVAC unit is compact and adapted for placement below the living area of motorhome so as to reduce the noise inside the cabin generated by the HVAC system and to reduce the center of gravity of the motorhome.Type: GrantFiled: October 4, 2001Date of Patent: August 17, 2004Assignee: Alfa Leisure, Inc.Inventor: Johnnie R.

Patent number: 6698818Abstract: A slideout-bed coupling system for a recreational vehicle that allows the bed to be positioned at desirable locations when the slideout is in retracted and extended configurations. By selectively coupling the slideout to the bed during the movement operation of the slideout, the bed's position relative to its surrounding can be controlled. In one embodiment, the bed's axis is oriented to be parallel to the longitudinal axis of the recreational vehicle, and the bed partially moves when the slideout extends. As such, when the slideout is in the retracted configuration, the bed can be positioned to provide selected access to the one or more side of the bed. When the slideout is in the extended configuration, the coupling system allows the bed to be positioned to provide enhanced accessible clearance to both sides of the bed.Type: GrantFiled: July 24, 2002Date of Patent: March 2, 2004Assignee: Alfa Leisure, Inc.Inventor: Johnnie R.

Patent number: 6688678Abstract: A vehicle frame with a low profile is designed to be suitable for attaching directly to an incomplete, preassembled motorized chassis to construct a motorhome. The vehicle frame includes planar bulkheads and a storage area floor that are attached to the frame and to the chassis so as to create a three-dimensional space frame that is highly resistant to bending and twisting forces as well as storage areas that extend the width of the motorhome. The motorhome with the frame mounts a heating, ventilation, and air conditioning (HVAC) system as well as heavy holding tanks within or below the plane of the vehicle frame so as to lower the center of mass of the motorhome to thereby improve vehicle handling and safety. Placement of the HVAC system within and/or below the vehicle frame obviates the need to position HVAC components on the roof of the motorhome thereby further lowering the center of mass and eliminating a source of liquid water condensation above the living space of the motorhome.Type: GrantFiled: January 28, 2003Date of Patent: February 10, 2004Assignee: Alfa Leisure, Inc.Inventor: Johnnie Robert Crean

Patent number: 6637804Abstract: A recreational vehicle having an expandable room, wherein the expandable room may be positioned in either a retracted or deployed configuration. In the deployed configuration, the room expands outwardly from the main housing of the vehicle so as to enlarge the overall living space area of the main housing. In the retracted configuration, the room slides inwardly into the main housing of the vehicle so as to reduce the width of the vehicle. The expandable room is equipped with at least one additional door on an outer wall in a manner so as to allow access to other rooms when expandable room is in the retracted configuration. The room may be extended in conjunction with an exterior slide-out assembly, wherein the deployed slide-out assembly produces a larger inner living space so as to accommodate the expanded room.Type: GrantFiled: October 30, 2001Date of Patent: October 28, 2003Assignee: Alfa Leisure, Inc.Inventor: Johnnie R.

Patent number: 6565144Abstract: A recreational vehicle having an expandable room wherein the room can be positioned in a retracted or deployed configuration. In the deployed configuration, the room expands inwardly into the main housing of the vehicle so as to enlarge the area of the room without displacing the fixtures and plumbing that are typically positioned adjacent an outer wall of the room. The room can be extended in conjunction with an exterior slide-out assembly wherein the deployed slide-out assembly creates a larger inner living space so as to accommodate the expanded room wherein the expanded room comprises a walk-in closet.Type: GrantFiled: August 31, 2001Date of Patent: May 20, 2003Assignee: Alfa Leisure, Inc.Inventor: Johnnie Crean

Patent number: 6505873Abstract: 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.Type: GrantFiled: December 6, 2000Date of Patent: January 14, 2003Assignee: Alfa Leisure, Inc.Inventor: Johnnie Robert Crean
