No. 663,425 Int. Cl. E04b 7/00 US. CI. 52-18 3 Claims ABSTRACT OF THE DISCLOSURE Housing core adapted to be permanently afiixed to ground contains kitchen and bathroom facilities and is permanently closed on bottom, top, and ends. One or both sides open and temporarily covered by at least two superposed roof panels hinged to upper edge of core side. Panels may be hinged together or telescopically arranged. When expanded, panels form roof extension joined to core. Roof panels may cover upper portion of core side, and superposed floor panels hinged to lower edge of core side cover remainder of core side, floor panels being expandable to form floor extension joined to core.
This invention relates to a building construction, and more particularly to a structure which can be optionally arranged compactly, for transportation to the building site, or expanded to provide many times the room area of the compact structure.
The structure is especially well suited for use as a vacation home.
It is an object of the invention to provide a building enclosure containing in compact relationship the essential bathroom fixtures and kitchen appliances required in a dwelling, and collapsible roof and floor panels permanently attached to the enclosure and capable of being oriented to define room area adjacent to the enclosure.
It is a further object of the invention to provide such a structure with a roof panel arrangement of special character whereby the size of the adjacent room can be made larger than with conventional structures of this type, and which permits the creation of a variety of roof designs not possible with such conventional structures.
To achieve these and other objectives, the invention provides a generally rectangular core unit permanently closed on top, bottom, and ends. The core contains complete bathroom and kitchen facilities needed in a residence, and is adapted to be permanently secured to the ground and connected to conventional water, electricity, and possibly gas, supplies. At least one side, and preferably both sides, of the core are open to permit access to the facilities within, and a multiple panel arrangement is hinged along the top edge of each open side. For purposes of shipping the core to the building site, the panels are arranged in superposed relation and lie parallel to the open side of the core so that the panel arrangement serves to close the core side and protect the interior. When the core is fixed at the site, the panel arrangement is swung upwardly to provide an extension of the top of the core, the extension serving as a roof for a room adjacent to the core. The roof panels may all be hinged together so that, although very compact when in superposed relation, they open to cover an area several times the width of each individual panel. In addition, the hinged relationship affords the opportunity to erect a flat, a peaked, or other roof design, as desired. In the alternative, the panel hinged to the core may be hollow and telescopically enclose the remaining panels when they are arranged in superposed relation, the nested panels being moved out of each other when the arrangement is expanded to form a roof.
3,462,891 Patented Aug. 26, 1969 Additionally, the width of the roof panels may be such that, when compacted, they cover only a portion of the open core side, the remainder of the core side being covered by a superposed arrangement of hinged-together floor panels. One of the floor panels is hinged along the bottom edge of the core, and when the arrangement is opened into a flat, horizontal condition, it provides a floor for the room area adjacent to the core.
Additional features and advantages of the invention will be apparent from the following description in which reference is made to the accompanying drawings.

FIG. 2 is a plan view of the core unit;
FIG. 3 is a perspective view of core unit provided with roof panels according to this invention;

FIG. 10 is an enlarged perspective view of a roof support post of FIG. 7; and
FIG. 11 is a cross-sectional view through an alternative construction of a roof panel arrangement.
The building structure chosen to illustrate this invention includes acore unit 19 having a permanently closedbottom wall 20,top wall 21, andend walls 22. The sides of the core are open to provide access to the facilities within.
The arrangement of facilities within the core may, of course, be varied as desired, but an example of the plans which may be used is shown in FIG. 2. The kitchen area houses arange 23, asink 24, and arefrigerator 25, and the bathroom area includes atoilet 26, a sink 27, and ashower 28. Ahot water heater 29 is adjacent to both the kitchen and bathroom, and a closet 30 is next to the bathroom.
In FIGS. 3-6, thecore 19 is shown fixed on concrete piles 33, and it is assumed that the plumbing and appliances are suitably connected to utility supplies (not shown). In the embodiment illustrated in these figures, each open side of thecore 19 is completely covered, when in compacted condition, by two superposed panels adapted to be expanded to form a roof. On one side, theroofforming panels inner panel 34 is hinged along its upper edge to the top edge of the core side byhinges 36, and the lower edges of the two panels are also hinged together, byhinges 37. On the other side of the core, thepanels
The embodiment of the invention illustrated in FIGS. 7-10 shows how a peaked roof may be achieved with multiple hinged panels, as well as a self-contained floor. In this example, the upper portion of each open core side is covered, when in compacted condition, by four superposed panels adapted to be expanded to form a roof, and the lower portion of each core side is covered by three superposed panels adapted to be expanded to form a floor. On one side, the roof-formingpanels outermost panel 43 is hinged along its upper edge to the top edge of the core side by apiano hinge 47, and the remaining panels are hinged together in order byhinges 48. On the other side of thecore 19, the panels 4346 are shown in opened condition forming a roof for a room adjacent to the core.
On one side of the core, the floor-formingpanels outermost panel 51 is hinged along its lower edge to the bottom edge of the core side by apiano hinge 54, and the remaining panels are hinged together in order byhinges 55. On the other side of the core, the panels 51-53 are shown in opened condition in a single horizontal plane forming a floor for the room adjacent to the core.Columns 56 for supporting the roof may rest on concrete piles, and each column carries an inwardly-projectingmember 57 which fits between the upper face of the opened floor panels and the lower face of the roof panels. If desired, anangle member 58, which may be formed of a suitable plastic, may be used to cap the peak between adjacent roof panels to prevent leakage through the joint.
The alternative form of roof panel arrangement shown in FIG. 11 involves telescoped panels. One edge of ahollow panel 61 is hinged to the upper edge of the core side by ahinge 62. Slidably nested within thepanel 61 is apanel 63. When the roof is collapsed, theentire panel 63 fits within thepanel 61, whereby the panels are in superposed relation. However, when the roof is opened, thepanel 63 is slid almost completely out of thepanel 61, suitable means being provided to prevent complete separation of the panels. Obviously, as many panels as desired may be telescopically arranged in this way.
The invention has been shown and described in preferred form only, and by way of example, and many variations may be made in the invention which will still be comprised within its spirit. It is understood, therefore,
4 that the invention is not limited to any specific form or embodiment except insofar as such limitations are included in the appended claims.
