Application October 9, 1940, Serial No. 360,372
This invention relates to a portable house or similar structure that can be readily assembled and disassembled.
The chief objects of the invention are to pro- Vide a portable house of sturdy but inexpensive construction which can be put together and taken apart by unskilled labor without tools in a relatively short time; which can be used Without a floor or platform if desired, and without any bracing means such as the guy wires that must be used with a tent.
It is also an object of the invention to provide a portable house which when disassembled can be stacked in a small space for ease in transportation, storage, and handling.
It is also an object of the invention to provide a portable house which will withstand adverse wind and rain conditions so that it can be comfortably occupied for long periods of time as a semi-permanent structure.
The portable house of the present invention comprises, basically, corner posts, side posts, and interchangeable side wall panels. The panels may be solid or formed with door and window openings as desired. The panels and posts are interconnected by easily operated fastening means, such as wing nuts and bolts. All the panels are exactly the same size and bolt-receiving apertures are formed in exactly corresponding positions on all the side posts and corner posts and along the sides of all the panels. Consequently the panels are fully interchangeable:
each panel can be used in any position desired,
i. e., at the front, side, or back of the house, and the panels do not have to be numbered or otherwise marked for identification during assembly.
A roof of any desired construction may be used in connection with the house as long as it is readily detachable from the other parts of the house. It may be a sheet of canvas, or a roof structure of hinged panels may be used as hereinafter described.
The house of the invention may be set up directly on a level piece of ground if desired or it may be mounted on any suitable flooring such as the usual type of wooden tent platform. In the latter case means such as angle irons may be provided for securing the house to the platform. If desired ropes and stakes may be used to secure the house to the ground or platform where it is set up, but in View of the rigidity of the house these ropes can be extended closely along the sides of the house and need not be extended away from the house as in the case of tent guys. This is an important advantage as it conserves space and eliminates the danger of tripping over the ropes and stakes.
To achieve ease in transportation and storage each of the side panels may be hinged at its center. If the panel includes a door extending substantially over the entire height thereof, the door may also be hinged as well as the remaining parts of the panel constituting the door frame. The posts and any elongated roof members such as the ridge-pole may also be hinged if desired but this is not usually necessary as such members are light in weight and consequently are easily carried and handled.
While a feature of the invention is that a post of a very simple nature can be used, special forms of posts as hereinafter described, affording more support to the panels, may be used where a more rigid structure is desired.
Further objects and features of the invention will be apparent from the following description of a preferred embodiment of the invention taken in conjunction with the accompanying drawings in which:
Fig. 1 is a perspective View of a portable house embodying the principles of the invention.
v Fig. 2 is a section on the line 2-2 of Fig. 1 showing a detail of a side wall panel.
Fig. 3 is a fragmentary elevation of the portion of a side panel along the hinged joint thereof, looking from the inside.

Fig. 5 is a section through a side post along the line 55 of Fig. 1.
Fig. 6 is a section similar to Fig. 5 a modified form of side post.
Fig. 7 is a perspective View corresponding to the upper part of Fig. l but with the roof removed.
Fig. 8 is a section along the line 88 of Fig. 1.
Fig. 9 is a section along the line 9-9 of Fig. 8.
Fig. 10 is a section along the line iii-l0 of Fig. 1.
Fig. 11 is a section through a corner post along the line HII of Fig. 1.
Figs. 12 and 13 are sections similar to Fig. 11 but showing modified forms of corner post.
Referring to the drawings, the portable house of the invention, in the embodiment shown, comprises eight sidewall panels I5a-l5h (see Figs. 1 and 7) hereinafter referred to collectively as the panels i5. Each of these panels is of the same size, for example 6' high by 4' wide by A" thick, so that a panel can be used at any desired position in the house.
but showing At the sides of each panel are bolt-receiving apertures l6 (Fig. 3), one series of apertures along each side of the panel and spaced from the edge thereof, say by 1 inch. These apertures are formed in the same relative positions on all the panels, for the purpose of making the panels interchangeable.
The panels I5 are mounted between corner posts I! and side posts [8, 18a. each of said posts having portions overlapping the sides of two adjacent panels and provided with corresponding bolt-receiving apertures.
Referring particularly to Fig, 11 which shows a preferred form of corner post, it will be seen that the post consists of two sheets of material I9, 20 arranged at right angles and nailed or cemented together. Although a simple lap joint is shown, a mitre or other special form of joint may also be used. A strip of material 2| is arranged at the inside meeting corner of sheets I9, 20 to act as an abutment for the panels l5. Preferably this strip is made of resilient material such as sponge rubber so as to provide a tight seal between the panels and post.
An important reason for using the abutment strip 2| is in connection with the interchangeability of the panels. If the panels were allowed to lap one another in the manner of sheets I9, 20, the apertures it of one panel would have to be a different distance from. the panel edge than the apertures of the other panel. By providing the abutment strip 2i, the apertures of all the panels, and the apertures on both sides of the same panel, can be arranged at the same distance from the panel edge.
It will be seen from Fig. 11 that bolts 22 are passed through the registering apertures of the panels and corner post and cooperating wing nuts 23 are screwed up on the b01135 to hold the parts firmly together. At the inside the bolts also extend through individual angle pieces 24 preferably of metal (see also Fig. 7) The wing nuts are arranged on the outside of the structure so as to be quickly and easily operable.
Some of the many possible modifications of the corner post are shown in Figs. 12 and 13. Fig.
12 shows a unitary corner post Ila which may be a molded plastic or extruded metal element. Fig. 13 shows a corner post lib with a jointed tongue and groove construction. In the case of both Figs, 12 and 13, the post itself comprises a double wall structure extending the entire height of the panel so that the individual angle pieces 24 of Fig. 11 are not used. The continuous double wall structure of course adds greater rigidity to the post and to the house as a whole.
Referring now to Fig. 5 which shows a preferred form of side post, it will be seen that the post consists of two parallel sheets of material 25, 26 secured together in spaced relationship by an intermediate abutment strip 21. The sheets 25, 26 and the strip 21 may be cemented or nailed together.
The abutment strip 27 is preferably made of resilient material such as sponge rubber, the thickness of the abutment strip is such that the sheets 25, 26 will be spaced apart a distance slightly greater than the thickness of the panels l5for example a distance of where the panels are thick. In assembly, bolts 22 having associated wing nuts 23 are passed through the registering apertures of the sheets 25, 26, and intermediate panel I5. Upon tightening the wing nuts 23 the rubber abutment strip is flattened from the dotted line position to the full line position shown in Fig. 5, thereby forming a tight seal between the post and panels.
Fig. 6 shows a modified form of side post consisting of only a single sheet l8. With this post individual backing elements 28, preferably of metal, are used corresponding to the angle pieces 24 of Fig, 11.
It will be understood that either form of side post is provided along its edges with a series of bolt-receiving apertures corresponding in location to the apertures of the panels. The distance from the apertures of the side post to the edge of the abutment strip 21 (Fig. 5) or to the center line of the post it (Fig. 6) is the same as the distance from the apertures of corner post I! to the portions of the corner post acting as abutments for the panels. As a result of this, interchangeability of the panels is assured.
Referring again to the sidewall panels l5, it will be seen that the same are hinged along a central horizontal line so as to be foldable outwardly of the house. Thus, panel |5a consists of the two halves 2%, 35 connected by hinges 3|. As shown in Figs. 2 and 3, a strip of material 32 is secured along the upper edge of the lower half 35 of the panel with part of the strip projecting above said edge to form a stop for the hinging movement of the upper half 29 of the panel. This relieves strain on the hinges 3|. The strip 32 also reinforces the panel half where the hinges 3| are connected thereto. Referring to Fig. 3 it will be seen that, at the positions of the hinges, rectangles 33 cut out from the strip 32 are secured to the panel half 29 as reinforcement for the hinges.
The upper panel half 29 (see Fig. 1) is shown as having a window opening 34 formed by cutting out a. rectangular portion 35 of the panel. The portion 35 is replaced in the opening to serve as a shutter, being hinged at its upper edge to the panel by any suitable hinges or, as shown, by a continuous flexible strip 36 which may be of rubberized fabric so as to be waterproof. A suitable latch 31 may be provided at the lower edge of the shutter and the shutter may be retained open when desired by a stick or prop.
The next sidewall panel I517 is shown as including a door 38 which is hinged at 39 so as to be foldable with the remainder of the panel and also hinged at 40 so as to be capable of opening and closing movement after the house has been set up. Suitable latches 4! are provided to lock the door in closed position.
It will be understood that, once the panel l5b is assembled with the corner post and side post at its margins, there will be no tendency for the door to collapse or fold at its hinges 39.
The panels E and 15d shown at the side of the house are substantially the same as the panel [5a described above. The shutter 35 of panel 15d is shown as partially opened to reveal a screen 42 extending over the window opening. The panels l5el5h may also be the same as panel l5a or may be solid panels without windows or doors.
Attention is directed to the modified hinging shown in connection with panels I50 and |5d and involving the use of a continuous strip of flexible material similar to the strips 35 used for hinging the shutters 35. The hinges 3i are shown below strip 43 and are preferably mounted in the panel so that they do not project substantially beyond the surface thereof. Also the flexible strip may be cut out where it overlies the hinges to reduce the bulk thereof. The strip 43 could also be used without any hinges 3l' or a continuous piano hinge could be used with or without strip 43. The joint between the two panel halves need not be a simple joint as shown in Fig. 2 but could be a rabbet joint. By the use of a rabbet joint and a continuous flexible waterproof strip, an extremely water-tight arrangement can be provided.
Referring now to Figs. 1 and 7, the corner posts I! and two of the side posts l8a are the same height as the sidewall panels. However, the other two side posts l8 extend upwardly beyond the panels, for example these posts can be 6' 9" high when the other posts are 6 high. At their upper ends the side posts 18 are formed with slots 44 to receive a ridge-pole 45 which may be, for example, 8' 6 x 2 x A". This ridgepole is provided with an upper surface 46 of resilient material such as sponge rubber.
Hinged to the ridge pole 45 are rafters 45a shown in Fig. 7. The outer ends of these rafters are slotted and are received in complemental slots in the side posts I 8a. The left-hand side of Fig. 7 shows the rafter and side post before engagement while the right-hand side of Fig. 7 shows these parts engaged. Due to the hinged connection of the rafters to the ridge-pole, the rafters can be folded up against the ridge-pole when the house is disassembled.
The roof 4! of the house is shown as formed of three pairs of hinged panels 41a, 41b, 410. Each individual panel (6 in all) may be 3 x 4' 4" x The hinged ends of the roof panels rest on the rubber surface of the ridgepole 45 while their free ends are supported on and extend beyond the sidewall panels I50, ld and 15g, l5h. The front and rear roof panels 41a, 41c rest on the sidewall panels, and the center roof panel 411) overlaps and rests on the front and rear roof panels as shown in Figs. 1,
8, 9 and 10. A resilient rubber strip 48 may be used between the roof panels. By the use of these separate, overlapping roof panels, good protection can be obtained even if some warping occurs.
Fastening means such as hooks and eyes 49 are arranged between the free edges of the roof panels and the side panels so that the roof panels can be pulled down onto the top of the side panels. This action also results in a tight joint between the hinged ends of the roof panels and the rubber surface 46 of the ridge-pole 45.
As shown in Figs. 1 and 8 a flexible strip 58 may be arranged across the joint at the hinged edges of the roof panels and between said panels and the hinges 5|. The strip 50 may be of rubberized fabric or a tough flexible building paper such as sold under the name Sisalkraft, and which can be repeatedly bent without breaking, can be used.
In the triangular spaces between the tops of panels [5a, Nb and the roof, gable members 52 are provided. These are shown as screened but solid gables could be used if desired. As shown in Fig. 4, downwardly projecting strips 53 are secured to the bottom of the gable member so that said member can be slid over the top of the repective panel. For additional protection a cover 54 of canvas or other impervious material may be secured over the gable member by hooks 55. It is preferable to use a cover of transparent material such as Pliofilm so that light is not shut off. Transparent material such as a transparent plastic could also be used for the gable member itself in the case of a solid gable. It will be understood that gable members are also mounted on the rear sidewall panels l5e and I5) not shown in Fig. 1.
From the foregoing description the manner of assembling the portable house of the invention should be apparent. Preferably two of the sidewall panels are assembled with an intermediate corner post while fiat on the ground. Then the subassembly so formed can be stood up and the other sidewall panels and posts added thereto. When all the parts of the sidewalls are in position except the last panel, the parts have sufficient flexibility so that they can be spread apart to permit insertion of the last panel between the respective corner and side posts, even if doublewall posts are used.
It will be understood that, as all the sidewall panels are identical in their size and shape and in the position of the bolt-receiving apertures therein, and as all the posts have bolt-receiving apertures in the same positions, any sidewall panel may be placed at any part of the house desired. The panels do not have to be numbered or otherwise identified for guidance in assembly. The position of the various side panels may be changed upon successive uses of the house.
After assembly of the sidewall panels and posts, the ridgepole 45 is next placed in position in the slots of the side posts l8 and the rafters are moved on their hinges to a position above the slots of the side posts |8a and pushed down into said slots.
The front and rear roof panels 41a, 410 are next placed over one side of the roof in folded position, extending from the ridgepole to one side wall. By pushing up with a stick on the free edge of the upper roof panel of each pair where it overhangs the side wall, the folded panel can then be opened like a book, said upper roof panel being allowed to swing over and fall upon the sidewall panel at the other side of the roof. If two people are erecting the house, While one stays outside the house and pushes the roof panel over as indicated above, the other can station himself inside the house to check the fall of said panel with a stick and lower same into position on the sidewall panel. The center roof panel is then applied in a similar manner.
The gable members 52 are slid into position, lifting the respective roof panels for this purpose as may be necessary. Finally the hooks and eyes 49 are connected to secure the roof panels, and consequently also the gable members, in position.
In the drawings, no flooring has been shown in connection with the house, as it has been found that the house may be erected on the ground without any flooring and is entirely self-supporting and extremely resistant to adverse wind and weather conditions. A canvas sheet may be used as a floor if desired to keep moisture out. Also, if desired, the house may be mounted on a floor such as a wooden tent floor or platform and, in such a case, the side-wall panels or posts may be connected to the floor by angle brackets, guy wires or other means.
If guy wires are used either for fixing the house to a platform or to the ground, these wires may extend from an upper corner of the house at one side to a stake adjacent the diagonally opposite lower corner of the house at the same side. In other words, the guys do not have to extend outwardly from the house as in the case of tent guys. This means that more houses may be accommodated in a given space and there is no danger of tripping over the guy wires.
Although a roof structure consisting of panels has been shown a sheet of canvas supported by the ridge-pole rafters, and sidewall panels could be used instead.
The side wall panels of the house of the invention may be made of wood or composition board such as Masonite, Cellotex, or Weatherwood. It has been found that good results can be obtained by using the products sold under the names of Weatherwood Denseboard and Weatherwood Structoboard, the latter grade being stronger and more weather-resistant. The posts and roof panels may be made of the product sold under the name of Weatherwood Hardboard which is a still harder composition material, or metal or plastics could be used. Another form of sidewall panel that could be used comprises a frame of wood or metal with canvas or screening stretched thereover.
The house of the present invention has a large field of use, both indoors and outdoors. Indoors it can be used as a playhuse, darkroom for photographic purposes, for subdividing a large room into individual cubicles or dressing rooms, or for other sub-division purposes. In the latter case, no roof may be required or desired. Outdoors, the house of the invention may be used as a temporary or semi-permanent cabin, for housing troops, for housing refugees and for isolation cabins in emergencies, for camping trips, as a guest house or beach cabana.
The house may be made of any size desired by adding side posts and sidewall panels. The house shown, when disassembled and the sidewall panels and roof panels folded over as permitted by the hinging thereof will occupy a space of only about 4 X 3 X 6 except for the posts, ridge-pole, and rafters. If desired the latter could also be hinged but this is generally unnecessary as they are light in weight. The house of the invention may therefore be transported readily by automobile for camping or week-end trips and can be set up by one man without tools in a short time-considerably less than one hour. With two experienced persons it is possible to assemble or disassemble the house in about minutes.
While specific dimensions are referred to in the above description it will be understood that these have been given by way of example only as the individual parts of the house and the house as a whole may be made of any size desired. Also the sidewall panels need not be hinged or may be hinged along a difierent line from that shown, depending on the size of the panels and the requirements as to transportation and storage. The invention is susceptible of numerous changes and modifications in addition to those suggested above and it is intended for the appended claims to cover all such changes and modifications that fall within the spirit of the invention.
