Abstract

A sliding mechanism for moving a slide-out compartment of a vehicle includes a guide member, a sliding member, and a gear. The gear is used to move the sliding member relative to the guide member. The sliding member and the guide member cooperate with each other to move the slide-out compartment between an extended position and a retracted position.

wherein the another guide member and the another sliding member cooperate with each other to move the slide-out compartment between the extended position and the retracted position.

17. The sliding mechanism of claim 16, comprising support elements coupled between the guide member and the another guide member to provide a rigid base assembly which includes the guide member, the another guide member, and the support elements, the support elements being separate from a frame of the vehicle.

18. The sliding mechanism of claim 16, comprising supports which are coupled between the ends of the sliding member and the another sliding member to provide a rigid slider assembly which includes the sliding member, the another sliding member, and the supports.

19. The sliding mechanism of claim 16, comprising a timing assembly which moves telescopically between one position where the gear and the another gear move in unison and another position where the gear and the another gear move independently of each other.

2. A sliding mechanism for moving a slide-out compartment of a vehicle, the sliding mechanism comprising:

a guide member which is open on a longitudinal side;

a sliding member which cooperates with the guide member to move the slide-out compartment between an extended position and a retracted position, the sliding member being at least partially disposed in an interior channel defined by the guide member; and

a gear which engages the sliding member to move the sliding member relative to the guide member;

wherein the sliding member is positioned between the gear and the longitudinal side of the guide member.

20. The sliding mechanism of claim 2, wherein the gear is coupled between opposing side walls of the guide member.

21. The sliding mechanism of claim 20, wherein the guide member defines an interior channel, the opposing side walls defining at least a portion of the channel.

22. The sliding mechanism of claim 2, wherein the gear is positioned to rotate on an axis which is in an interior channel defined by the guide member.

23. The sliding mechanism of claim 2, wherein the sliding member at least substantially closes the longitudinal side of the guide member.

24. The sliding mechanism of claim 2, wherein the gear engages a plurality of holes in the sliding member to move the sliding member relative to the guide member.

25. The sliding mechanism of claim 2, comprising an electric motor used to drive the gear.

26. The sliding mechanism of claim 2, wherein the guide member is shaped substantially like a C.

27. The sliding mechanism of claim 2, wherein the guide member includes a roller which is used to guide movement of the sliding member.

28. The sliding mechanism of claim 2, wherein the sliding member is positioned to support the slide-out compartment through the longitudinal side of the guide member.

29. The sliding mechanism of claim 2 comprising

another guide member which is open on a longitudinal side;

another sliding member which cooperates with the another guide member to move the slide-out compartment between the extended position and the retracted position; and

another gear which engages the another sliding member to move the another sliding member relative to the another guide member;

wherein the another sliding member is positioned between the another gear and the longitudinal side of the another guide member.

30. The sliding mechanism of claim 29, comprising support elements coupled between the guide member and the another guide member to provide a rigid base assembly which includes the guide member, the another guide member, and the support elements, the support elements being separate from a frame of the vehicle.
