I 11211;? EWWW Aug. 9, 1960 B. COOPER INTERLOCKING BUILDING SECTIONS AND METHOD OF MAKING BUILDINGS Filed Feb. e, 1956 2 Sheeis-Sheet 2 IIIIIIIIIlI/IIIi/IIIIII/ Fatented Aug. 9, 1960 INTERLOCKING BUILDING SECTIONS AND METHOD OF MAKING BUILDINGS My invention relates to sections for buildings and more particularly to portable sections adapted to fit quicklytogether and to be dis-assembled quickly and without a number of tools for easy economical transportation from one location to another and to the method of making buildings from interlocking sections.

In particular I have observed that people who live in house trailers use a variety of methods of enlarging the living space by buildings along side such trailers or constructing alongside thereof various enclosures which are referred to variously as cab-anas, or as lanais, or other terms. Such structures in general consist of roofed and enclosed areas usually enclosed on three sides with one side open to the trailer so that easy access may be had to the trailer from such structure, which'I shall refer to throughout the balance, of this application as a cabana.

It is usually desirable that such structure be economical,

be quickly transportable, easily assembled and disassembled by unskilled persons (frequentlyelderly persons) and that such structure provide reasonable insulation qualities and reasonable living comfort. I have observed many structures of this nature and I have observed many types of portable buildings and building panels.

It is not my intention to limit this invention to the use of such panels in building cabanas for trailers. My invention can just as readily be used to accomplish complete construction on all four sides of a building and can also be used where desirable to construct merely one or two walls for dividing rooms and the like.

I have observed many pro-formed building panels for such cabana use including building panels of metallic material which may be interlocked by a variety of means usually based upon a sliding channel or tongue and groove type structure. Such structures are diflicult for the average person to assemble and usually require, in

addition to other difiiculties, a large number of bolted or otherwise screwed or connected panels in various connections. Further than this, it is frequently necessary to have special panels and expensive structure in connection with the hanging of doors and door frames of such units.

this isnot the exclusive material for such use. Any type metallic, plastic, or other substance which may be formed into the appropriate shape may be used. 7

Basically, in my invention, individual building panels aredesigned having at each end thereof interlocking lugs.

wSaid lugs are so designed as to slide together from the side and firmly engage each other. At the other edge of such panels I have provided on one end a decorative molding which is integral with the panel and which has a slight overlap to engagethe next joining panel. On the opposite 'side of each panel and catercorner from said molding is another molding which, in cross section, has a mushroom appearance and which stands up and above the paneling a distance to engage a deconative panel which slides behind it. This molding is so placed that the :decorative panel, when behind said molding, acts as a look .so that the panels as they have been put together cannot then disengage until this decorative panel is removed. At the corner or end of said decorative panel there is one key decorative molding strip which is placed inposition .to hold such panels in the locked position and such key decorative molding strip is either attached with screws, clips or otherwise and holds the'entire structure together.

' My invention'will be most completely understood and easily recognized "and understood by those skilled in the art by reference to the attached drawings in which:

' Figure 1 is an elevation of one side of such a building;

Figure 2 is a sectional View of the section 11 of Figure 1;

Figure 3 is a fragmentary section through the plane 2-2 of Figure l.

Referring in more detail to Figure 1, there is illustrated a side of a building consisting of corner section 1, interlocking

sections

8, 21, and 27, with decorative moldings 11 and 30,'window 18 in frame 19, door fname 32, door 20, end section 35,

outer wall skin

46, 47, and 48, decorative strip 49 and roof 50.

Referring in more detail to Figure -2 of the drawings the corner post 1, seen here in cross sections, is composed of a hollow lengthy section, preferably an aluminum extrusion, having formed thereon at one corner thereof, and extending the length thereof,-a decorative molding .2 with an overhanging lip 3. Lugs or flanges 4 and 5 are formed on one edge of said corner section 1 and lugs 6 and '7 are formed upon the edge at degrees to the edge containing lugs 4 and 5, all of said lugs extend the length of said corner post 1. Another lengthy section 8, preferably an extrusion, contains lugs or flanges 9 and 10 extending the length thereof, which lugs are cooperable with lugs 6 and 7 and may be slid into position with said lugs. Extending the length of section 8 is a decorative molding 11 with a lip 12, corresponding to the molding .2 with lip 3 on the corner post 1. The corresponding section 42 on the other corner of the corner post 1 contains as a part thereof the lugs 14 and 15 extending the length of said section 42, which interlock with lugs 4 and 5 on corner post 1. Section 8 has a lug 16 extending the length thereof, into which one leg of a channel 17 fits. The channel 17 fits into the open side of section 8 as shown, extends about the window 18 and forms a closure therein into which the window 18 in its frame 19 fits. The Window 1% is broken for conservation of space in this drawing, as is the door 20. Section 21 is similar to section-8 and the lug 22 corresponds to the lug 16, the lugs23 and 24' correspond to the lugs 9 and 10; all of said lugs extending the length of said section 21. Section 21 contains an added element of molding 25 on a stem 26. Section 27 engages with section 21 by the

lugs

28 and 29 extending the length of said section 27. The molding 30 with the lip 31, both extending'the length of section 27, holds the section firmly. The channel 32 is fastened to section 27 by

screws

33 and 34 or other suitable means. The channel 32 extends up the sides and on the top of the door 20 and is fastened to one-end section 35 by

screws

36 and 37 or other suitable means. The door 20 is fastenedto the channel 32 by suitable hinges 38. The interior of'thewall is covered by

panels

39, 40, and 41, of plywood, or other suitable material. Exposed edges of such panels, as at the window opening are covered .by a small channel of metal or

other material

44 and 45. Molding 43 holds the comer of

panels

40 and 41.

Figure 3 illustrates the method of holding the outer wall 46 skin of combed aluminum or other suitable material in place in the lug 16 of section 8 and joined in by channel 17 within said lug.

In above description there is seen a description of the manner in which the various portions of this unit fit together. However, it must be observed that the foregoing description does not indicate the manner of fitting these units together. Therefore, this additional explanation is provided. Again referring to Figure 2 it is seen that the corner post 1 has fitted on to it by use of the interlocking logs the sections 8 and 42. These sections quite obviously slide inward into the corner post and thusly lugs 9 and 10 and 14- and 15 come into sliding engagement with the lugs 6, 7, 4, and on the corner post 1. The

lips

3 and 12 of the decorative moldings. 2 and 11 serve as stops and when they come in contact with the edge of the interlocking unit of course can slide no further. The decorative panels '44 and 41 are used on the interior of the walls. These panels, as it will be seen, slide against the interior of the sections 42 and 8, and by being held in place by a corner molding 43, which may be in any of a number of shapes including a simple angular shape.

In further examination of the drawing Figure 2 it will be noted that section 21 which is used on the opposite of the window 18 has a decorative molding 25 standing upon a stem 26. The interior decorative panels 39 are slid behind this molding 25. The panel on the opposite side of the molding 25 from the panel 39 has purposely been omitted from Figure 2 so that there will be no confusion in showing exactly how the interlocking system works.

In operation and practical application the building formed by the use of these materials is formed very quickly and simply by making four foot wide sections or sections of any other convenient width and sliding them together by means of the interlocking arrangement as indicated. It will be observed that one section would be formed by the sections 8 and 21 with the window 18. Another such section will be formed by the

sections

35 and 27 with the door 20.

It will be observed that instead of the corner post 1 in its position that other complete building unit panels similar to the one composed of sections 8 and 21 and the window 18 could be slid on to this unit and so on indefinitely to make a wall of any length whatsoever. In addition a door section can be interspersed at any desired time.

It will be observed that the basic principle involved in this building is the principle of forming basic sections as heretofore set forth consisting of two of the interlocking units with a window or with a door in place and then interlocking these together with other sections.

The corner posts 1 provide the means by which the direction of the wall is changed by 90 degrem to form an. angular or rectangular enclosure.

It will be quite clear to anyone skilled in the art that the preferable method of manufacturing the

basic sections

1, 8, 21, etc. will be by extrusion. However, this is not to be construed to limit my application and it is clear that any other means of forming may be used. In addition it will be observed that the exact shape of the lugs by which the interlocking arrangement is obtained is immaterial and that a wide variety of lug shapes may be designed. The essential here is that they may be slid together without the necessity of lifting one panel to put it into cooperative juncture with another panel.

The outer metallic skin 46 is deemed a desirable type of outer wall arrangement since it does not require upkeep and is easy to handle. However, it is quite clear that wood or any other substance might be used rather than this metallic skin as is indicated in the drawing.

It will be observed that the method of forming a wall by the use of these interlocking sections is the most simplified and speedy method of forming a wall of any predetermined length. A number of illustrations have been indicated for forming a complete building by attaching various building panels to my basic building posts or sections.

By merely adding or taking away sections it is possible to build a building almost as large as desired with virtually no lost time.

It is felt that the process of forming a building from these sections has been adequately described however, it will be clear to anyone skilled in the art that the various procedures might be reversed and the sequence of operation changed without affecting the teaching and scope of my invention. For example the window 18 might be placed in position at any time and need not be placed in position prior to forming of the sections together. Likewise it will be observed that the direction of the interlocking lugs might be reversed and that a channel 32 might be reversed in such a manner that they fasten on the inside nather than the outside of the

sections

27 and 35.

It will be observed also that the

basic building sections

1, 8, 21, etc. are in general of relatively small size (about 2 inches wide and approximately 8 feet high) that any height might be used and any size might be used within rather large limitations. Such, of course, will not in any manner \alfect the scope or teaching of my invention and it is intended that my invention include all such limitations. It is to be observed that the method of interlocking of my wall sections together contemplates all similar methods by which basic wall sections might be slipped together and quickly fastened together with or without the aid of a large number of screws, nuts, bolts, and the like.

It is clear that a number of modifications and variations of the present invention as described may occur to those skilled in the art after a careful study of my disclosure herein. All such modifications and variations properly within the sphere, scope and teaching of my invention are intended to be included and comprehended herein as fully as if they had been described, illustrated and claimed herein. For example, among other things, the shape of the lugs, and whether one, two, three, or four, or any number of lugs might be used is immaterial, and in addition the shape and exact construction and configuration and whether upon the right, left, front, or back side of the panel of the various molding edges indicated are immaterial. Further than this, the exact shape and size of the panels and the exact means of mounting together are immaterial. to the function and cooperation of the various elements concerned.

It is not intended that any of the limitations which might apparently exist in the drawings should be considered as limitations but merely that the present illustration is for illustrative purposes only and is intended to nowise limit the scope of the invention which must be interpreted in the light of the prior arts and inventive claim with due consideration for the doctrine of equivalents.

The exact composition, configurations, constructions, positioning and cooperative relationships of the various component parts are not critical and may be modified to a large degree within the sphere of and without altering the scope of the present invention.
