Abstract

An extendible slideout room having a roof, floor, and sidewalls is moveable between a retracted position and an extended position within a lateral wall of a vehicle such as a motorhome, a boat, or virtually any type of trailer. In the retracted position, the roof, floor and two side walls of the slideout room are disposed within the vehicle, with a third outer side wall positioned in sealed contact with the vehicle'"'"'s lateral wall about the periphery of the slideout room. When extended, the slideout room'"'"'s roof, floor and sidewalls project outwardly from the vehicle'"'"'s lateral wall in sealed contact with the vehicle'"'"'s wall. Elongated screws rotationally coupled to the slideout room'"'"'s outer side wall at their respective distal ends are inserted through respective threaded fittings fixedly attached to the vehicle'"'"'s lateral wall, with each screw disposed adjacent a respective corner of the room. A toothed sprocket is attached to the distal end of each screw, with the sprockets coupled together by means of an endless chain. A drive sprocket connected to a drive motor is also coupled to the chain for displacing the chain and rotating the screws in unison. Rotation of the drive sprocket in a first direction extends the slideout room, while rotation of the drive sprocket in a second, opposed direction retracts the room within the vehicle. The drive mechanism including motor, sprockets and chain are coupled to and move with the slideout room during extension and retraction.

Claims

1. For use in a vehicle having a plurality of first side walls, an arrangement comprising:

a slideout room disposed in an opening in one of said first side walls and including a floor, a ceiling, an end wall and a plurality of second side walls, said slideout room further including a plurality of corners defined by intersections of said floor and said ceiling with each of said second side walls;

a plurality of elongated screws each disposed adjacent a respective corner of said slideout room and having a respective longitudinal axis oriented generally perpendicular to said one of said first side walls of the vehicle, each of said screws further including a distal end coupled to the end wall of said slideout room and a proximal end disposed in the vehicle;

a plurality of threaded fittings attached to said one of said first side walls of the vehicle about the aperture therein, wherein each of said screws is threadably inserted in a respective one of said fittings;

a plurality of sprockets coupled by means of an endless chain, wherein each of said sprockets is fixedly mounted to a proximal end of a respective one of said screws;

drive means coupled to said endless chain for displacing said chain and rotating each sprocket and screw combination in a first direction for retracting said slideout room within the vehicle through the aperture therein or for rotating each sprocket and screw combination in a second, opposed direction for extending said slideout room out of the vehicle through the aperture therein, wherein said drive means is coupled to and moves with said slideout room; and

a plurality of slide members extending between the distal and proximal portions of said slideout room for engaging said one of the vehicle'"'"'s first side walls adjacent the aperture therein for facilitating sliding displacement of the slideout room between the extended and retracted positions.

2. The arrangement of claim 1 further comprising a plurality of retainer fittings each coupled to a distal end of a respective screw and attached to the end wall of said slideout room.

3. The arrangement of claim 1 further comprising a first seal member attached to said one of first side walls of the vehicle and disposed about the aperture therein, and a second seal member disposed about a periphery of the end wall of said slideout room for engaging said first seal member when said slideout room is fully retracted.

4. The arrangement of claim 3 further comprising a third seal member disposed about a proximal periphery of said slideout room for engaging said first seal member when said slideout room is fully extended.

5. The arrangement of claim 1 further comprising an elongated screw and sprocket combination disposed adjacent the ceiling of said slideout room and midway between opposed side walls of said slideout room and coupled to said drive means by means of said endless chain.

6. The arrangement of claim 5 further comprising first and second idler sprockets engaging said endless chain and disposed adjacent to said screw and sprocket combination.

7. The arrangement of claim 1 wherein said drive means includes a drive motor and drive sprocket combination coupled to said endless chain for rotationally displacing said sprocket and screw combinations.

8. The arrangement of claim 7 further comprising an idler sprocket engaging said endless chain and disposed adjacent of said drive sprocket and one of said sprockets mounted to a screw.

9. The arrangement of claim 8 further comprising a plurality of chain guides disposed on a proximal portion of said slideout room and engaging said endless chain for maintaining said chain aligned with said sprockets and under tension.

10. For use in a vehicle having an extendible slideout room, wherein said slideout room includes a floor, a ceiling, an end wall, and a plurality of side walls, an arrangement for displacing said slideout room through an aperture in a lateral wall of the vehicle between an extended position and a retracted position, said arrangement comprising:

a plurality of elongated screws disposed in a spaced manner about the periphery of the slideout room with each of said screws including a distal end coupled to the slideout room and a proximal end disposed in the vehicle and having a sprocket attached thereto, wherein each of said screws is inserted through and threadably coupled to the lateral wall of the vehicle;

an endless chain engaging each of said sprockets disposed on the distal ends of said screws;

drive means coupled to said endless chain for rotating said sprocket and screw combinations in a first direction for extending the slideout room from the vehicle through the aperture in the lateral wall of the vehicle or for rotating said sprocket and screw combinations in a second, opposed direction for retracting the slideout room into the vehicle; and

a plurality of slide members for engaging the lateral wall of the vehicle adjacent the aperture therein for facilitating sliding displacement of the slideout room between the extended and retracted positions.

11. The arrangement of claim 10 further comprising a plurality of retainer fittings each coupled to a distal end of a respective screw and attached to the end wall of said slideout room.

12. The arrangement of claim 11 further comprising an elongated screw and sprocket combination disposed adjacent the ceiling of said slideout room and midway between opposed side walls of said slideout room and coupled to said drive means by means of said endless chain.

13. The arrangement of claim 12 further comprising first and second idler sprockets coupled to said endless chain and disposed to adjacent to said screw and sprocket combination.

14. The arrangement of claim 13 wherein said drive means includes a drive motor and drive sprocket combination coupled to said endless chain for rotationally displacing said sprocket and screw combinations.

15. The arrangement of claim 14 further comprising an idler sprocket engaging said endless chain and disposed adjacent said drive sprocket and one of said sprockets mounted to a screw.

16. The arrangement of claim 15 further comprising a plurality of chain guides disposed on a proximal portion of said slideout room and engaging said endless chain for maintaing said chain aligned with said sprockets and under tension.
