3 Claims. (Cl. 20-2) This invention relates to a portable building, and more particularly to a house or cabin structure made up of separate parts which may be easily assembled and disassembled and which when disassembled may be formed into a compact assemblage for convenient storage or transportation.

The invention has for an important object the provision of a portable house or cabin embodying foldable side units and separate corner post units, adapted to be fitted together and having means for releasably securing the same in assembled relation.

Another object of the invention is to provide a portable house made up of side units and corner posts adapted to be releasably connected together and which are shaped for interfitting engagement to form a strong, rigidly braced, structure when fitted together.

A further object of the invention is the provision of a portable house having a collapsible roof structure embodying a covering of flexible material and adjustable supporting means therefor which are adjustable to securely hold the covering in a tightly stretched condition.

Another object of the invention is to provide a portable structure of the kind referred to having foldable sides of uniform dimensions, one of which sides includes a door which is foldable therewith and which is also hinged for opening and closing in the usual manner when the structure is assembled.

A further object of the invention is the provision in a portable house of folding sides therefor having Window openings and including closure members for the openings and also having means for supporting the closures in positions to serve as awnings for the windows.

The above and other important objects and advantages of the invention may best be understood from the following detailed description constituting a specification of the same, when considered in conjunction with the annexed drawings, wherein Figure 1 is a perspective view of the invention in fully assembled condition; 7

Figure 10 is a fragmentary, horizontal, cross-sectional view, showing details of structure of a side unit of the invention having a door incorporated therein; and

Figure 11 is a side elevational view, on an enlarged scale, illustrating a latching element of the invention.

Referring now to the drawings in greater detail, the invention is illustrated herein in connection with a building structure of generally rectangular figuration, having folding sides and corner posts, which are adapted to be assembled and secured together to form a rectangular enclosure, upon which a collapsible roof is removably supported, it being understood that the invention is applicable to houses of other configurations, and is not to be limited to the particular construction and arrangement illustrated herein. Each of the side walls is formed of upper and lower sections or panels, 10 and 12, respectively, hingedly connected together along adjacent horizontal edges, having suitable hinges, such as those indicated at 14, whereby the upper sections may be folded down upon the lower sections.

Each of the sections comprises a rectangular frame, of wood, or other suitable material, and the upper sections 10 may be covered with suitable screen 16, while the lower sections may be of solid sheet material 18.

For the purpose of assembling the sections into a rectangular enclosure, corner posts 20 are provided, each of which is formed with a longitudinal groove 22 along one edge of each of its outer faces, whose depth is preferably the same as the thickness of the frame portions of the sections or panels, and into which the ends of the sections may be fitted in assembling the structure. Latching elements 24, of hook shape, are attached to each section, in position to extend beyond the ends of the sections in overlying relation to the outer faces of the corner posts, and the corner posts have bolts 26 extending outwardly from their outer faces, in position to be re ceived in the hook portions of the latching elements, and are provided with Wing nuts 28, whereby the sections are removably secured to the corner posts.

One of the side walls has a central door formed with upper and lower hingedly connected sections 30 and 31, folding with the sections of the side wall, and which is also hingedly connected thereto, as indicated at 32 in Figure 10, to be opened and closed when the structure is in assembled condition, the upper door section 30 being screened, while the lower door section is closed by solid sheet material.

It will be apparent that the side walls may be folded in the manner illustrated in Figure 2, and may then be formed into a compact bundle with the corner posts and the collapsible roof, to be more fully described hereinafter, for the purpose of convenient storage and transportation.

The collapsible roof of the invention comprises roof supporting members made up of telescopingly arranged inner and outer elements 36 and 38, respectively, said outer elements 38 taking the form of rods, whose outer ends are bent downwardly, as indicated at 40, and are perforated, for pivotal attachment to perforated brackets 42, as by means of pins 43, whereby said outer elements may :be foldeddownwardlytolie along the corner posts, and may be moved to .upper'positions extending inwardly from the corner posts for insertion into inner elements 36, to place the roof supporting members in position to support .the roof. Theinner elements 36 are of tubular shape, and are pivotallyattached at their inner ends to perforated brackets 44, as by means of pins 46, the brackets 44 being secured to the upper side of a central plate 48, whereby the inner elements may be folded into parallel relation, or may be moved to extended .positions to receive the inner ends of the outer elements, when the roof is assembled. The center plate'48 also has a centrally positioned upwardly extending bolt 50 for a purpose hereinafter pointed out. The inner elements 36 are also provided with set screws 52, by which the inner and outer elements are adjustably secured together.

It will be apparent that with the side walls and corner posts assembled; the outer elements 38 may be swung upwardly and inserted in the inner elements 36, the center plate 48 being then moved to a central position between the walls, and the set screws .52 tightened, whereby the roof supports may be securelyheld in position to support the roof.

A roof cover 56, of generally rectangular configuration is supported on the roof-supports, the cover having a central opening 59, through which the bolt 50 of the center plate 48 extends, and the marginal portions of the cover extending downwardly over the upper edges of the walls.

The marginal portions of the cover maybe provided with spaced openings 58, through which turn'buttons 60 secured to the upper margins of the walls may be extended, to removably attach the cover to the walls. The marginal portions of the cover may, if desired,'be turned inwardly over the upper edges of the walls, as seen at '62 in Figures 7 and 9. When thus assembled the roof is of pyramid shape.

The upper screen sections '10 of the Walls form window openings, which may he provided with closure members 64, which also serve as awnings, the same being preferably formed of flexible fabric such as canvas, or the like having marginal openings along their inner margins, corresponding to the openings 58 of the roof cover, and through which the turn buttons 60 may be extended, to attach'the closures to'the walls. The inner marginal portions of the closures are preferably positioned beneath the outer margins of the roofcover, as indicated at 65, v

in Figure 9, to provide water shedding arrangement. The outer margins of the closures may be formed with hems, indicated at 66, through which U-shaped rods 68 areextended, whose side arms are received in tubular elements 70, pivotally connected to brackets 72 carried by the walls, below the upper edges of the walls. The tubular elements 70 are provided with set screws 74, by which the arms of the rods 68 may be adjustably secured thereto, whereby the position of the closures may be adjusted as desired. Each of the closures may have one or more chains 76, or similar tension elements, shown in Figure 9, connected at their outer ends to the rods .68, and at their inner ends to the Walls, above the screens 16, to prevent stretching of the fabric of the closure.

By this construction, it will be evident that the closures may be raised or lowered, as desired, by suitably adjusting the rods 68, in the elements 70, whereby the closures may serveias awnings, or may be moved to positions to close thewindow openings.

provided between'thesections-for the accommodation of 'the'closures -7-4-with their supporting elements, whereby these parts will be enclosed between the sections and protected thereby when the structure is folded into a stack or bundle.

A somewhat modified form of the invention is illustrated in Figure 8, wherein the screen 16' of the upper Wall section 10' is provided with a frame 80, which is removably attached to the section, as by means of bolts 82, provided with wing nuts 84.

One of the latch elements 24 of the invention is illustrated in detail in Figure 11, this element having a hook portion 25 formed with a bill, whose throat 86 is somewhat narrowed, whereby the latch elements may be snapped into position over the bolts 26, to hold the sections in contact with thecorner posts, for convenience in assembling the structure.

To assemble the structure, the folded side walls may be placed in positions to form a rectangle as illustrated in Figure 2, the upper sections being swung outwardly away from-the lower sections 12, to act as props to hold the lower sections upright. The corner posts may then be placed in position at each corner, the latch elements 24 being hooked over the bolts 26 to secure the lower sections to the posts. When the corner posts are thus connected to the wall sections the bolts 26 are prevented from slipping out of the hooks 25, due to the restricted throats86 of the hooks.

With the sides and corner posts thus connected the upper sections 10 may then be swung upwardly into engagement with the posts and secured thereto, to complete the walls.

The elements 38 of the roof supports are then swung upwardly and inserted into the elements '36, to assemble the roof supports. By suitably adjusting the elements 36 and 38 and tightening the set screws 52 the center plate may "be supported in a central position above the walls with the roof supports extending radially outwardly to the corner posts.

'ture.

It .will thus'be seen, that the invention, constructed as described above provides a portable building which is easily assembled and disassembled and whose parts may be readily stacked and folded into acompact unit for convenient storage or transportation.

The inventionhas been disclosed hereinin connection witha certain specific embodiment of the same, but it will be understood that this is intended by way of illustration only, .and that numerous changes can be made in construction and arrangement of the various parts without departing from the spirit of the invention or the scope of the appended claims.
