Abstract

A trailer having a slideout mechanism for moving an extensible cabin between a retracted position wherein the cabin is substantially inside the trailer and an extended position wherein the cabin is substantially outside the trailer. The slideout mechanism comprising an extension means for positioning the cabin between the retracted and extended positions and a leveling means for vertically positioning the cabin floor between a raised position wherein the cabin floor is substantially above the trailer floor and a lowered position wherein the cabin floor is substantially level with the trailer floor. In one embodiment, the leveling means comprises a frame member having a predetermined profile for controlling the vertical movement of the outboard end of the cabin floor as the cabin is positioned between the retracted and extended positions. In other embodiments, the leveling means comprises a cam assembly or a riser assembly for controlling the vertical position of the cabin floor.

Claims

1. A slideout mechanism for use in a vehicle having a floor, a wall, an opening in the wall, and an extensible cabin movable through the opening between retracted and extended positions, said slideout mechanism comprising

extension means for positioning the cabin between the retracted position wherein the cabin is disposed substantially inside the vehicle and the extended position wherein the cabin is disposed substantially outside of the vehicle,

the cabin having walls and a cabin floor vertically movable relative to the cabin walls, and

leveling means for vertically positioning the cabin floor independently of the cabin walls between a raised position wherein the cabin floor is above the vehicle floor and a lowered position wherein the cabin floor is substantially level with the vehicle floor.

2. The mechanism as set forth in claim 1 wherein the leveling means comprises at least one leveler assembly for vertically positioning an outboard end of the cabin floor between the raised and lowered positions when the cabin is at the extended position.

3. The mechanism as set forth in claim 2 wherein the leveler assembly comprises at least one riser assembly for vertically positioning the outboard end of the cabin floor between the raised and lowered position.

4. The mechanism as set forth in claim 3 wherein the riser assembly comprises upper and lower members slidably engaging each other such that movement of the lower member causes vertical movement of the upper member, and

the upper member supportably engages the cabin floor for movement between the raised position wherein the cabin floor is positioned substantially above the vehicle floor and the lowered position wherein the cabin floor is positioned substantially level with the vehicle floor.

5. The mechanism as set forth in claim 4 wherein the riser assembly comprises an actuator for moving the lower member.

6. The mechanism as set forth in claim 4 wherein the lower and upper members have opposing inclined faces such that movement of the lower member causes the inclined faces to slide relative to each other.

7. The mechanism as set forth in claim 1 wherein the leveling means comprises at least one outboard leveler assembly and at least one inboard leveler assembly for vertically positioning the outboard and inboard ends, respectively, of the cabin floor between the raised and lowered positions when the cabin is positioned at the extended position.

8. The mechanism as set forth in claim 7 wherein each leveler assembly comprises at least one riser assembly for vertically positioning the cabin floor between the raised and lowered position.

9. The mechanism as set forth in claim 8 wherein each riser assembly comprises upper and lower members slidably engaging each other such that movement of the lower member causes vertical movement of the upper member,

the upper member supporting the cabin floor for movement between the raised position wherein the cabin floor is positioned substantially above the vehicle floor and the lowered position wherein the cabin floor is positioned substantially level with the vehicle floor.

10. The mechanism as set forth in claim 9 Wherein the riser assembly comprises an actuator for moving the lower member.

11. The mechanism as set forth in claim 9 wherein the lower and upper members have opposing inclined faces such that movement of the lower member causes the inclined faces to slide relative to each other.

12. The mechanism as set forth in claim 8 wherein the riser assembly is synchronized to vertically position the outboard end of the cabin floor in unison with the inboard end of the cabin floor for maintaining a level orientation of the cabin floor between the raised and lowered positions.

13. The mechanism as set forth in claim 1 wherein the extension means comprises an actuator connecting the vehicle and the frame member for positioning the frame member between the retracted and extended positions.

14. The mechanism as set forth in claim 1 wherein the extension means comprises at least one frame member having one end slidably supported by the vehicle and another end rigidly attached to the cabin for supporting the cabin.

15. The mechanism as set forth in claim 14 wherein at least one of the frame members has a plurality of holes for receiving corresponding fingers projecting from the periphery of a roller, an actuator operatively connected to the roller such that rotation of the roller causes linear movement of the frame members between the retracted and extended positions.
