Expandable building with telescoping enclosures and hingedly connected barriers

Claim 2

A building construction unfoldable from a compact storage condition into an extended condition defining a cabin-type enclosure comprising first and second rectangular housing sections, each said first and second housing section being defined by a side wall, a front wall, a rear wall, a floor, a first rectangular arrangement of frame members bounding a top opening, and a second rectangular arrangement of frame members bounding a side opening in opposing relation to said side wall, said first and second housing sections having operative positions telescoped one within the other defining said compact storage condition and being slidably movable therefrom into said extended condition thereof in which said side openings are in adjacent position and said side walls, front and rear walls, and floors cooperate to define said cabin-type enclosure, a first roof construction for said first housing section consisting of two hingedly connected panels one of which is hingedly connected to said frame member bounding said top opening and adjacent said side wall thereof, a second roof construction for said second housing section consisting of one panel hingedly connected to said frame member bounding said top opening adjacent said side wall thereof, said first and second roof constructions being pivotable from horizontally oriented storage conditions within each of said top openings into operative erect conditions cooperating to define a three-dimensional roof construction of triangular shape in cross section on top of said internal cabin-type enclosure, and gable members hingedly connected along the tops of said front and rear walls pivotable from horizontally oriented storage conditions within each of said top openings into vertically oriented erect conditions in supporting relation to said panels of said first and second roof constructions, whereby said three-dimensional roof construction contributes both head room and an aesthetic gabled appearance to said building construction.

Claim 3

A building construction unfoldable from a compact storage condition into an extended condition defining a cabin-type enclosure comprising first and second rectangular housing sections, each said first and second housing section being defined by a side wall, a front wall, a rear wall, a floor, a first rectangular arrangement of frame members bounding a top opening, and a second rectangular arrangement of frame members bounding a side opening in opposing relation to said side wall, said first and second housing sections having operative positions telescoped one within the other defining said compact storage condition and being slidably movable therefrom into said extended condition thereof in which said side openings are in adjacent position and said side walls, front and rear walls, and floors cooperate to define said cabin-type enclosure, a first roof construction for said first housing section consisting of two hingedly connected panels one of which is hingedly connected to said frame member bounding said top opening and adjacent said side wall thereof, a second roof construction for said second housing section consisting of one panel hingedly connected to said frame member bounding said top opening adjacent said side wall thereof, said first and second roof constructions being pivotable from horizontally oriented storage conditions within each of said top openings into operative erect conditions cooperating to define a three-dimensional roof construction of triangular shape in cross section on top of said internal cabin-type enclosure, and gable members hingedly connected along the tops of said front and rear walls pivotable from horizontally oriented storage conditions within each of said top openings into vertically oriented erect conditions in supporting relation to said panels of said first and second roof constructions, whereby said three-dimensional roof construction contributes both head room and an aesthetic gabled appearance to said building construction.
