Slide-out room mechanism for a vehicle
View Patent ↗A slide-out system having a first and second slide-out assembly which are fixed to a first and second side of a slide-out room respectfully. Each assembly preferably includes an upper and lower gear rack fixed to the respective side of the slide-out room. An electric motor is connected to a drive gear that engages the top gear rack, driving movement of the slide-out room. This movement is distributed or synchronized with a lower portion of the room by an axle having a top gear engaged with the top gear rack and a bottom gear engaged with the bottom gear rack. Since the axle is not directly connected to the motor, it acts solely as a secondary synchronization mechanism between the top and bottom of the room.

10. The slide-out system of claim 4 , wherein said upper bearing block and said lower bearing block are engaged with a vertical channel.
11. The slide-out system of claim 10 , further comprising a clamp member shaped to selectively engage said vertical channel and an inner surface of a vehicle wall.
12. The slide-out system of claim 10 , further comprising a clamp member shaped to selectively engage said vertical channel and an outer surface of a vehicle wall.
13. The slide-out system of claim 4 , wherein said first horizontal gear rack and said second horizontal gear rack each include a geared track adhered to a gear track mounting channel of each of said first horizontal gear rack and said second horizontal gear rack; wherein said gear track mounting channel has a substantially uniform rectangular shape.
14. The slide-out system of claim 4 , wherein said motor is accessible and removable from an interior of a vehicle when said slide-out system is installed on a slide-out room of a vehicle.
15. A slide-out system for a vehicle, comprising:
a first horizontal gear rack horizontally mounted on a first sidewall of a slide-out room;
a second horizontal gear rack located below said first gear rack and horizontally mounted on said first sidewall of said slide-out room;
a drive gear connected to a motor and engaged with said first horizontal gear rack;
a synchronizing mechanism connected to and synchronizing movement of said first horizontal gear rack and said second horizontal gear rack; said synchronizing mechanism comprising a rotating vertical synchronizing linkage having an upper synchronizing gear engaged with said first horizontal gear rack, and a lower synchronizing gear engaged with said second horizontal gear rack;
wherein said drive gear, said motor, and said synchronizing mechanism are fixed within a first vertical channel member, and said first vertical channel member is configured for mounting to a first vehicle wall.
16. The slide-out system of claim 15 , wherein said vertical channel comprises a fixed flange portion and a clamp engagement portion; wherein said clamp engagement portion is shaped to accept and orient a clamp member in a position generally parallel to said flange portion.
17. The slide-out system of claim 16 , wherein said flange portion and said clamp member each include a vertical channel containing adhesive.
18. The slide-out system of claim 16 , wherein said fixed flange portion is oriented to engage an outer surface of a vehicle wall and wherein said clamp member is positioned to engage an inner surface of said vehicle wall.
19. The slide-out system of claim 15 , further comprising:
a third horizontal gear rack configured for horizontal mounting on a second sidewall of a slide-out room;
a fourth horizontal gear rack located below said third gear rack and configured for horizontal mounting on said second sidewall of said slide-out room;
a second drive gear connected to a second motor and engaged with said third horizontal gear rack;
a second synchronizing mechanism connected to and synchronizing movement of said third horizontal gear rack and said fourth horizontal gear rack;
