Abstract

A lifting system can be used to move an item between a use position and a stowed position in a structure such as a vehicle or home. The item may be an article of furniture, an appliance, a storage unit, a platform, workbench, or the like. The lifting system may be motorized and/or utilize a flexible drive to move the item. The lifting system may be used to reciprocally move the item between the use position and the stowed position in the structure.

Claims (40)

1. A structure comprising:

a floor and a ceiling;

an item that moves vertically and at least substantially translationally between a lowered position where the item is positioned to be used and a raised position where the item is stored, the item including a first side and a second side positioned opposite the first side; and

a lifting system including a flexible drive member which moves along an endless path to move the item between the lowered position and the raised position;

wherein the item is positioned closer to the floor of the structure when the item is in the lowered position than when the item is in the raised position and the item is positioned closer to the ceiling of the structure when the item is in the raised position than when the item is in the lowered position;

wherein the item comprises at least one item selected from the group which includes a seating unit having a seat base and a seat back, a desk, a table, a workbench, an entertainment center, an appliance, a television, a sink, a cupboard, a cabinet, a shelf, a counter, and combinations thereof; and

wherein the lifting system is positioned adjacent to only the first side of the item so that the item is easily accessible from the second side.

2. The structure of claim 1 wherein at least a portion of the flexible drive member extends lengthwise in a vertical direction.

3. The structure of claim 1 wherein at least a portion of the flexible drive member is positioned inside a wall of the structure.

4. The structure of claim 1 wherein the flexible drive member includes a cable.

5. The structure of claim 1 wherein the lifting system includes a motor that moves the item between the lowered position and the raised position.

6. The structure of claim 1 wherein the item comprises at least one item selected from the group which includes a desk, a table, a workbench, an entertainment center, an appliance, a television, a sink, a cupboard, a cabinet, a shelf, a counter, and combinations thereof.

7. The structure of claim 1 wherein the item comprises at least one item selected from the group which includes an entertainment center, an appliance, a workbench, a television, a cupboard, a cabinet, a shelf, a counter, and combinations thereof.

8. The structure of claim 1 wherein the item comprises the workbench.

9. The structure of claim 1 wherein the structure is a recreational vehicle.

10. The structure of claim 1 wherein the item is positioned adjacent to the ceiling of the structure when the item is in the raised position.

11. The structure of claim 1 wherein the structure includes a storage area for one or more cars and the lifting system is positioned in the storage area.

12. A structure comprising:

a floor and a ceiling;

an item that moves vertically and at least substantially translationally between a lowered position where the item is positioned to be used and a raised position where the item is stored; and

a lifting system including a toothed wheel which engages a support member coupled to the structure to move the item between the lowered position and the raised position;

wherein the item is positioned closer to the floor of the structure when the item is in the lowered position than when the item is in the raised position and the item is positioned closer to the ceiling of the structure when the item is in the raised position than when the item is in the lowered position;

wherein the item comprises at least one item selected from the group which includes a seating unit having a seat base and a seat back, a desk, a table, a workbench, an entertainment center, an appliance, a television, a sink, a cupboard, a cabinet, a shelf, a counter, and combinations thereof; and

wherein the toothed wheel moves vertically as the item moves between the lowered position and the raised position.

13. The structure of claim 12 wherein the lifting system is configured to reciprocally move the item between the lowered position and the raised position.

14. The structure of claim 12 wherein the item comprises the workbench.

15. The structure of claim 12 wherein the structure is a recreational vehicle.

16. The structure of claim 12 wherein the item is positioned adjacent to the ceiling of the structure when the item is in the raised position.

17. A structure comprising:

a floor and a ceiling;

an item that moves vertically and at least substantially translationally between a lowered position where the item is positioned to be used and a raised position where the item is stored,. the item including a first side and a second side positioned opposite the first side; and

a lifting system including a roller chain used to move the item between the lowered position and the raised position where at least a portion of the roller chain extends lengthwise in a vertical direction;

wherein the item is positioned closer to the floor of the structure when the item is in the lowered position than when the item is in the raised position and the item is positioned closer to the ceiling of the structure when the item is in the raised position than when the item is in the lowered position;

wherein the item comprises at least one item selected from the group which includes a seating unit having a seat base and a seat back, a desk, a table, a workbench, an entertainment center, an appliance, a television, a sink, a cupboard, a cabinet, a shelf, a counter, and combinations thereof; and

wherein the lifting system is positioned adjacent to only the first side of the item so that the item is easily accessible from the second side.

18. The structure of claim 17 wherein the lifting system is configured to reciprocally move the item between the lowered position and the raised position.

19. The structure of claim 17 wherein the item comprises the workbench.

20. The structure of claim 17 wherein the item is positioned adjacent to the ceiling of the structure when the item is in the raised position.

21. The structure of claim 1 wherein the structure is an immobile structure including living quarters.

22. The structure of claim 1 wherein the structure is a home.
