A coupler for connecting and disconnecting a first hydraulic connector and a second hydraulic connector. The coupler has a first end and a second end. The coupler first end has a threaded opening adapted to combine with a threaded connector. The coupler second end has an opening with several members movable relative to the longitudinal axis of the coupler. The movable members have a first position wherein they are moved outward to make the opening larger and a second position wherein they are moved inward to make the opening smaller. The opening in the coupler second end is adapted to receive a threaded connector when the movable members are in their first (larger) position. After a portion of the threaded connector is inserted into the opening, the members are moved to their second (smaller) position thereby securing the threaded connector to the coupler second end.
A means to average the left and right tire height positions relative to the chassis of a vehicle having an independent suspension system. The averaging means uses a rigid member having a first end and a second end wherein the first end is combined with the driver's side independent suspension and the second end is combined with the passenger's side independent suspension. As each side of the vehicle's suspension moves up and down, the ends of the rigid member also move up and down. A sensor determines the average height of the rigid member and communicates that information to the ride-height control system.

A mechanism to affect the coordinated movement of an expandable room in a recreational vehicle. The mechanism comprises a drive chain assembly and a lift assembly. The drive chain assembly has a pair of drive chains (upper and lower) that move generally vertically along vehicle structural members and then the chains are redirected for horizontal travel as the main hydraulic cylinders are actuated to extend or retract the expandable room. The movement of the upper and lower drive chains is synchronized by a rack-and-pinion mechanism. The lift assembly controls vertical movement of the room so that when the room is fully extended, the floor of the vehicle and the floor of the expandable room are substantially flush. The lift assembly comprises at least one lift cylinder for raising and lowering the room. The lift cylinder is vertically combined with the lower end of the structural member.

A synchronizing cylinder comprising a large diameter barrel and a small diameter barrel. The barrels are separated by a junction that is not fluidly sealed so that fluid can be communicated between them. The volume of the large diameter barrel is twice the volume of the small diameter barrel. The barrels comprise a first chamber adapted to communicate fluid to and from a hydraulic manifold, a second chamber adapted to communicate fluid to and from a first mechanism cylinder, and a third chamber adapted to communicate fluid to and from a second mechanism cylinder. The volumetric ratio of the barrels allows an equal volume of fluid to be communicated to and from the mechanism cylinders even though the volume of the barrels is not the same.

Hydraulic slidable storage for a recreational vehicle
A slidable storage tray adapted to be hydraulically actuated between a retracted position wherein the tray is nested inside a vehicle's storage compartment and an extended position wherein at least a portion of the tray is located outside of the vehicle's storage compartment. The slidable storage tray is dual directional so that it extends from either a first side or a second side of the vehicle. The hydraulic circuit comprises a first hydraulic cylinder and a second hydraulic cylinder. The rod of the first cylinder is attached to the vehicle/storage compartment frame and the rod of the second cylinder is attached to the slidable storage tray. The two hydraulic cylinders are attached together so their barrels cannot move relative to one another. The two hydraulic cylinders are facing the same direction so that their rods both extend in the same direction.

Synchronization cylinder having chambers with different volumes
A synchronizing cylinder that allows for the synchronized movement of multiple hydraulic mechanism cylinders having different sizes and volumes. In one embodiment, the synchronizing cylinder has a first chamber in fluid communication with a first mechanism cylinder and a second chamber in fluid communication with a second mechanism cylinder. The first mechanism cylinder has a first volume and the second mechanism cylinder has a second volume wherein the volume of the first mechanism cylinder is smaller than the volume of the second mechanism cylinder. The volume of the fluid being pushed from (or received by) the first chamber in the synchronizing cylinder is less than the volume of fluid being pushed from (or received by) the second chamber in the synchronizing cylinder so that the first and second mechanism cylinders extend and retract at the same speed and distance regardless of the smaller size and volume of the first mechanism cylinder.

A seal assembly primarily for recreational vehicles that have an expandable room. The seal assembly seals the opening in a fixed wall of the vehicle through which the expandable room extends. The seal assembly includes a retainer that is attached to a fixed wall of the vehicles, the retainer holding a bulb-type seal properly in place. The retainer securely holds the bulb seal in place until it is compressed by the expandable room, and the retainer further functions to prevent the bulb seal from being crushed which could cause premature failure of the seal. The seal assembly also provides for relative movement in different directions between the meeting surfaces of the fixed room and moveable room. In this way, it acts as a low friction bearing surface while still maintaining a complete and positive seal at all times.
An assembly adapted to protect a vehicle with an expandable room by preventing water and debris on the roof of an expanded expandable room from being trapped or crushed between the expandable room and the body of the vehicle as the room is retracted. The assembly comprises an upper member and a lower member that mate at a pivoting connection. The upper member is attached to the outside surface of the vehicle above the expandable room. The lower member is pivotally combined with the upper member so that it hangs below the upper member and rests against the top edge of the expandable room. As the room is retracted, a spring urges a portion of the lower member to remain frictionally engaged with the roof of the expandable room so as to slide over the surface of the roof and remove water and other debris from the roof.
