Application July 23, 1954, Serial No. 445,217

6 Claims. (Cl. 189-444) To provide a composite unit of considerable strength in relation to its weight; and

To: permit manufacture of the parts. of the unit by mass production methods, at a relatively low unit cost.

For further comprehension of the invention, and of z the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claiins in which the various novel features of the invention are more particularly set forth.

Fig. 13 is a fragmentary perspective view ofa modified tie bar.

Fig. 14 is a fragmentary view of a modified coupling block.

The assembled unit shown in Fig. 1 is made up of five diflerent types of cooperating elements, shown in Figs. 2 through 7. These include a tie bar 24 (Fig. 2); a coupling block 22 (Fig. 3); a key retainer 24 (Fig. 4); a panel retainer 26 (Fig. 5); a panel 255 (Fig. 6); and aholding pin 3i) (Fig. 7).

The tie bar, four of which are used in assembling the unit, includes an elongated body 325 of square cross section. Cut into each corner of the body 32 is agroove of angular cross section, disposed radially of the body, each groove extending thefull length of the body. The grooves cooperate to define dovetail tongues 34 extending Patented Jan. 29, lfibd longitudinally of the body from end to end thereof, over the full area of each longitudinal surface or face of the body. The tie bar is hollowed out into a tubular form, to permit the passage of electric wiring (not shown) therethrough.

The'ends of the body are cut ofl squarely, and formed upon and extending beyond each end of the body is a pair of jaws 36, saidijaws being bowed inwardly toward oneanother.

Each coupling block22is of square or cubical formation, and all edges thereof arecut inwardly to provide, on each surface or face of the coupling block, a rectangular, flattened locking projection 38 having undercut sides.

Four of the coupling blocks are used in the assembly of a single building unit, one at each corner of the unit.

The key retainer 24 is fashioned from rigid sheet metal material, and. includes a flat, square, plate-like body ill, each edge of which is, integral with a flange or lip 42 that is turned inwardly atanjangle of 45 to the plane of the plate-like body. The opposite ends of each flange or lip 42 are cut away or beveled obliquely.

Four key retainers 24. are used in the: assembly of each unit, one ateach corner.

The panel retainer is also formed from rigid sheet metal material, and includes an elongated, rectangular, flat, plate-like body 44 integral at its opposite ends with end tongues or flanges 46. Each flange 4-6 is beveled at its opposite ends, and each flange 45 is obtusely related at an angle of 45 to the body 44-.

Integrally formeduponthe opposite side or longitudinal edges of the body 44, andextending the full length of the body, are sideflanges 43, these being turned under as shown in Fig. 5,,at acute angles to the body As shown in Fig. 9 the opposite ends of. each flange 43 are pointed, the pointed end portion of each flange 48 extending beyond. the adjacent end of body 44.

Four of the panel retainers 26 are utilized, one at each side of the building unit.

The panel member 28 is framed by the parts previously described herein, and is formed as a large, rectangular sheet of material shaped with a flat body 54?, integral at its several edges with narrow flanges 52, each of which is obtusely related to the body 50.

A single panel member 28 is used in the assembly of a single building unit.

In Fig. 7 there is shown a holding pin 3d] of wire material, having a U shape, the. opposite legs being of a springable nature, so as to be yieldably and resiliently sprung away from one another during the assembly of the panel. Each leg of the spring clip or holding pin 30 includes, at its free end, an inwardly turned finger 53.

In assembly of the building unit, the first step is to assemble a rectangular outer frame, composed of the tie bars and coupling blocks. Each tie bar is detachably connected at its oppositeends to coupling blocks 22, and to eifect the connection, one need simply shift the tie bar toward the associated coupling block, or vice versa as shown in Fig. 8, so as to engage jaws 36 with the undercut sides of the adjacent projection 33. The tie bar is thus engaged in end-abutting relation to the adjacent coupling blocks used at the corners of the building panel.

Since projections 38 are provided on all. faces of the coupling block, a single block can be connected to a plurality of tie bars. Not only can a single unit be con structed, but also, adjacent units, each formed as in Fig. i, can be connected in perpendicular planes, to permit assembly of the building without the necessity of tools or the like. Further, adjacent units can be connected in coplanar relation so that a number of units can be used to form asingle wall.

7 Each jaw 36 has an opening 54, and after the coupling blocks and tie bars have been assembled as discussed above, a clip St is applied in straddling relation to the jaws 36 (see Fig. 10), with the fingers 53 of the spring clip engaging in the openings 54 of the jaws 36. This lockably holds each tie bar assembled with its associated coupling blocks, preventing separation thereof in one direction. The assembled tie bars and coupling blocks define a rectangular-shaped opening, the dimensions of which are sufiicient to receive the panel member 59.

The panel member 5%) is now applied, with the flanges 52 thereof engaging in the angular grooves of the several tie bars, in the manner shown in Fig. 11. Panel retainers 26 are now slid lengthwise into position over a dovetail tongue 34 of a tie bar, the side flanges 48 of the p nel retainer engaging in thegrooves defined at opposite sides of said dovetail tongue, to hold Within said grooves the flanges 52 of the panel member. It will be understood that the panel retainers can be mounted on the front of the tie bars in the manner shown in Figs. 8 and 9, during the assembly of the tie bars with the coupling blocks.

When each panel retainer is shifted into a position in which it is co-terminous with its associated tie bar, an end tongue 46 of the panel retainer will be interlocked with the adjacent undercut side of a projection 38 of the coupling block 22, in the manner shown in Fig. 12.

Key retainers 2d are now applied, over each exposed projection 38, the inwardly turned lips 42 being engaged with its associated projection 38. Thereafter, the lips 42 will engage in the grooves provided in the coupling block, to hold the end tongues of the panel retainers in place.

This completes the assembly of the building unit, and the final unit will appear as in Fig. 1. This unit can be assembled with other units, as will be apparent, adjacent units being either normal to the illustrated unit, or in perpendicular relation thereto, whichever is desired.

In Figs. 13 and 14 there are shown modified forms of the tie bar and coupling block, respectively. The modified tie bar Ztl is in this instance of tubular formation, being shaped from sheet metal or the like. This lightens the construction. The actual functional characteristics and exterior configuration of the tie bar remains unchanged, the tie bar having rabbeted grooves 34 in each face thereof, extending the full length of the tie bar. The jaws 3t in this form can be made integral with opposite sides of the tie bar, as in the first form, and are shaped as in the first form of the invention.

in Fig. 14 a modified coupling block 22 is shown, said block being of open frame or skeleton construction, rather than solid as in the first form.' Again, the purpose is to lighten the structure without sacrificing strength.

Block 22 includes projections 38*, each of which projections is formed as a square, open frame 55, having arms 56 extending inwardly from the opposite ends thereof, the several arms 56 being integrally or otherwise fixedly joined at each corner of the block as shown, slots being shown between the projections and frame.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
