  • Publication number: 20020093214
    Abstract: A mobile living quarters unit incorporates a slide-out room which is moveable between an extended position providing an auxiliary living area when the unit is parked and a retracted position retracted into the unit when the unit is moved. A latching mechanism automatically latches the slide-out room to the mobile living quarters as the slide-out room is moved into the retracted position, and releases the room to permit outward movement of the slide-out room when the unit is parked and the slide-out room is extended.

  • Publication number: 20020084665
    Abstract: Transportable living quarters includes a main frame supporting a main living area and a slide-out room that slides between an extended and retracted position relative to the main living area. The actuation mechanism for extending and retracting the slide-out room includes a curved slider arm that causes the slide-out room to tilt slightly when moving into the fully extended or retracted positions. Upon extension, the slide-out room tilts outwardly to compress an inner compressible seal between sealing surfaces on the main living area and the slide-out room inner flange. Upon retraction, the slide-out room tilts in the opposite direction to compress an outer compressible seal between sealing surfaces on the outside of the main living area and the outer flange of the slide-out room. This tilting of the room results in a tighter seal at the top of the slide-out room that better isolates the living area from the outside elements.

  • Publication number: 20010008059
    Abstract: Transportable living quarters includes a main frame supporting a main living area and a slide out room which slides between an extended and retracted position relative to the main living area. An extendable member is mounted on the main frame and is rigidly connected to the slide out room floor, so that the weight of the slide out room is transferred from the floor of the main living to the extendable member as the slide out room slides between the retracted and extended positions. In one embodiment of the invention, the floor of the slide out room is leveled with respect to the floor of the main living area when the slide out room is moved to the extended position by bending of the extendable support member in response to the weight transfer.
