Lynch, 4826 Quince Road, Memphis, Tenn. Filed Jan. 20, 1960, Ser. No. 3,682 Claims. (Cl. 189-36) The invention relates broadly to sheet metal structures, and more particularly to framed corrugated sheet metal panels and to posts and connecting means utilized with the panels and posts for erecting fence-like enclosures, building walls and the like.

An object of the invention is to provide a prefabricated relatively lightweight corrugated sheet metal panel, including a rigid marginal frame, permanently secured thereto, the panel being adapted for use in conjunction with novel connecting means in the erection of fences, industrial fence type enclosures, building walls, doors, gates and the like.

A further object of the invention is to provide sheet metal posts and friction type clamp elements for use in conjunction with the prefabricated framed sheet metal panels for building fence type enclosures and the like, the construction being such that the posts need not be set with extreme accuracy, and the necessity for drilling holes for fastening elements in the panels and posts is entirely eliminated.

Another object of the invention is to provide structural assemblies of the above-mentioned character, wherein the prefabricated framed panels are readily adjustable relative to their supporting posts and also bodily removable or replaceable without disturbing the posts when required.

Still another object is to provide sheet metal structural means of the above-mentioned character, capable of a rather wide variety of uses, the structural means being extremely sturdy and durable, easy to erect and disassemble, readily transportable and economical to manufacture.

Other objects and advantages of the invention will become apparent during the course of the following detailed description.

Referring to the drawings in more detail, particularly FIGURES 5 through 13, the numeral 25 designates a relatively light gage sheet metal panel element which is disposed vertically in use and corrugated throughout its length preferably in the manner shown in FIGURES 5 and 7a. The particular shape of the corrugations 26 and 27 may be varied as found desirable, but the corrugations are uniform throughout the length of the panel element 25, so that the same is of uniform overall thickness throughout its length. The panel element 25 may be formed in any desired length and height so that it may be utilized in fabricating any preferred multisided enclosure or wall structure, such as the three-sided partial enclosure shown in FIGURE 6.

As shown in typical FIGURES 8 through 13, the vertically corrugated panel element 25 for any side of the enclosure shown in FIGURE 6 carries a top rail 23 or frame member, permanently rigidly secured thereto by welding at 29 and 30'. This top rail 28 is formed of relatively heavy gage sheet metal, and is quite rigid and extends continuously throughout the horizontal length of the particular panel element 25. The top rail 2S embodies an upper wall 31 which rests upon the top edge of the corrugated panel element 25, and an outer vertical wall 32 which is forwardly oiset or spaced from the panel element 25, as shown. The top rail 28 has an integral depending vertical ange 33, welded to the corrugations 27 at 30. The top rail also includes an inner depending vertical flange 34 welded to the corrugations 26 at 29.

Each corrugated panel element 25 further embodies a rigid bottom rail or frame member 35, permanently rigidly secured thereto by welding. The bottom rail 35, FIG- URE 8, is likewise formed of relatively heavy gage sheet metal and is coextensive with the top rail 28 and corrugated panel element. It comprises an outer vertical web 36, preferably ilush with the outer corrugations `27, a bottom inwardly directed horizontal web 37, an upper horizontal web 38, upon which the lower edge of the corrugated panel element 25 rests, and an integral inner upstanding longitudinal flange 39, secured by welding to the inner corrugations 26.

With reference to FIGURES 10 and 11, each corstiff or rigid. The opposite sides 41 and 42 of the endv rails 49 are permanently rigidly secured by welding to the corrugated panel element 25, as at 43.

It may thus be seen that each side or section of the three-sided partial enclosure illustrated in FIGURES 5 and 6 embodies one of the corrugated lpanel elements 25 of the proper length, and such panel element is bounded at its marginal edges by the top and bottom rails 28 and 35 and by the end rails 40. These rails thus form a continuous marginal rectangular rigid frame for each panel element 25 of the enclosure or like structure.

rIhe enclosure panels thus described are entirely unitary and prefabricated and caribe made in any desired length, height or thickness, as should be obvious. These prefabricated panel sections are capable of a wide variety of uses, one such use being illustrated in FIGURES 5 and 6 for forming a three-side partial enclosure for industrial use or the like.

The partial enclosure of FIGURES 5 and 6 embodies front and side panel sections 44, 45 and 46, and each of these panel sections is constructed from one of the panel elements 25 and the associated rails 28, 35 and 40, previously described.

The partial enclosure of FIGURES 5 and 6 embodies a pair of corner posts 47 and a pair of end posts 48', which may be set in the ground as at 49 without the necessity for extreme accuracy in setting the posts.

With reference to FIGURE 10, each corner post 47 embodies a pair of main vertically extending webs 48, arranged at right angles and forming the outer finished corners of the enclosure shown in FIGURE 6. Each corner post 47 has inwardly directed vertical flanges 49, at right angles to the webs 48 and coextensive vertically therewith and with the panels 44, 45 and 46. Inner ange extensions 50, parallel to the webs 48 and at right angles to the flanges 49, are arranged for abutting engagement with the outer sides 42 of the vertical end rails 40 of the panels.

As best shown in FIGURE 12, a plurality of vertically equidistantly spaced brackets 51 are secured by welding at 52 to the ange extensions 50. The brackets 51 eX- tend diagonally between the welds 52 as shown in FIG- URE 10. A corresponding number of readily detachable diagonal friction clamp brackets 53 of a shape similar to the brackets 51 abut the inner sides 41 of end rails 40. The clamping brackets 53 are apertured for the reception of bolts 54, which have screw-threaded engagement at 55 within screw-threaded openings of the permanently attached brackets 51.

By means of the construction shown for the corner posts and clamping means in FIGURE 10, it should now be apparent that the prefabricated panels 44, 45 and 46 may be readily adjusted horizontally or endwise and also vertically somewhat with respect to the corner posts 47 before the panels are rigidly clamped in place by tightening of the bolts 54. With this arrangement, it is unnecessary that the various posts be set in the ground with extreme accuracy, and consequently, the enclosure may be erected by unskilled labor at a great saving of money.

With reference to FIGURE 11, each end post 48 may be identical in cross sectional shape with the corner posts 47, and need not therefore be described in further detail. An L-shaped bar 56, coextensive in length with the end post 48 is welded at 57 to the ange extensions 50, as shown. A plurality of separable L-shaped frictional clamping brackets 58, preferably corresponding in number and spacing to the brackets 53, are provided at the end posts, and one leg 59 of each such bracket clampingly engages the inner side 41 of end rail 40 of the adjacent enclosure panel 45 or 46. The other leg 60 of each clamping bracket 48 engages the L-shaped bar 56 at 61. Each bracket 58 has its leg 59 apertured for the receptlon of a horizontal bolt 62, the latter having screw-threaded engagement at 63 within a screw-threaded opening formed through the L-shaped bar 56,

Prior to tightening the clamping bolts 62 of each end post 48, the enclosure panels 45 and 46 may be adjusted relative to the end posts 48 in generally the same manner described in connection with the adjustment of the panels relative to the corner posts 47.

With reference to FIGURES 8 and 9, sheet metal finishing caps 64 and 65 for the corner and end posts 47 and 48 are preferably provided. These finishing caps have outer vertical anges 65, apertured at 66 for the reception of sheet metal screws or the like, used to attach the tinishing caps to the respective corner and end posts. The finishing caps are also shown in FIGURES 5 and 6 of the drawings.

In connection with the invention thus far described, it should be understood that the prefabricated panels and associated corner and end posts and their frictional clamping means may be utilized to form fence-like enclosures of any desired size and shape, as well as partial enclosures of the type illustrated in FIGURE 6.

With reference to FIGURES 1 through 4, a modified type of industrial enclosure or the like has been shown, utilizing the same basic type of panel, post and frictional clamping means, described in detail in connection with FIGURES 5 through 13.

The enclosure shown in FIGURE 1 embodies panels 66, 67, 6?, 69, 78 and 71, all constructed in the same manner as previously described in connection with FIG- URES 5 through 13. The enclosure of FIGURE 1 also embodies a plurality of the corner posts 47 and associated elements, all previously described. Additionally, the enclosure of FIGURE 1 embodies a pair of gates 72 and 73, the detailed construction of which will be described hereinafter. The enclosure of FIGURE 1 also embodies a central or dividing panel 74, likewise identical in construction with any of the previously described panels 44, 45 or 46.

The employment of the panel 74 requires however the use of the enclosure of a pair of partition posts 75. With reference to FIGURE 3, each partition post 75 is formed of heavy gage sheet metal and includes vertically extending portions 76, generally U-shaped in cross section and having inner sides 77 to abut the sides 42 of panel end rail-s 40. An inwardly directed vertically extending post web 78 is welded to the post body portion 75 at 79. The web 78 carries a U-shaped extension 80, the side of which is adapted to abut the adjacent end rail 40 of partition panel 74. A plurality of vertically equidistantly spaced bracket plates 81 corresponding generally to the brackets 51 in number and spacing are welded to the post 75, centrally thereof, and at 82, as shown. Readily detachable L-shaped clamp brackets 83 having corresponding legs 84 engaging the rigid plate elements 81, and the other legs 8S of these clamp brackets clampingly engage the inner sides of the end rails 40 of the panels 70 and 71 or 67 and 68 to adjustably secure the same against post flanges 77. Bolts 85 engage through apertures in the clamp bracket legs 85 and have screw-threaded engagement with the plate elements 81 as shown in FIGURE 3.

In the light of the previous description in connection with FIGURES 5 through 13, it is ybelieved that the construction in FIGURES 1 through 4 will be obvious with- In FIGURES 14 through 16 of the drawings, there is shown a preassembled sheet metal panel 86, adapted to serve as a door or gate, such as the gates 72 and 73 shown in the enclosure of FIGURE 1, and the gate illustrated in FIGURES 17 through 23 to be described. The gate panel 86 is rectangular, as shown, and embodies a unitary relatively thin gage corrugated sheet metal panel element 87 substantially similar to the previously described panel element 25. As shown in FIGURES 14 through 16, the corrugated panel element 87 has a rigid marginal frame 88, including side frame members 89 and top and bottom frame members 90, mitered and welded at 91. r[he frame members 89 and 90 are identical in cross sectional shape, FIGURES 15 and 16, and comprise forwardly offset walls 92 and side or marginal wall-s 93, integral therewith, and arranged at right angles to the walls 92. Inwardly directed ilanges 94 of the walls 92 carry flange extensions 95, at right angles thereto, and abutting the forwardly projecting corrugations 96 of the panel element 87, around all four sides of the prefabricated panel. The flange extensions 95 are secured to the corrugations 96 by skip welding or the like. Rear flange extensions 97 integral with the Walls 93 overlap and abut the rear corrugations 98 of panel element 87 and are welded thereto around all sides of the panel 86. The frame sides 89 and 90, thus Welded to the corrugated panel element 87, render the prefabricated panel 86 extremely strong and durable, yet relatively lightweight.

FIGURES 17 through 20 illustrate a partial enclosure utilizing the prefabricated panel 86 as a horizontally swinging gate, in conjunction with another prefabricated pael 99, made exactly in accordance with the prior description in connection with FIGURES through 13. The embodiment of FIGURES 17-20 may also include one of the corner posts 47 and associated elements, previously described, one of the end posts 48 and associated elements, and a suitable gate post 100.

The gate panel S6 is hung from the forward face of the end post 48 by conventional hinges 101, as shown in FIGURES 17 and 19. Conventional latch mean-s 102 on the forward side of gate post 10th coacts with a suitable keeper 103 carried by the forward side and adjacent edge of the gate panel 86.

In View of the detailed description relative to FIG- URES 5 through 13, and FIGURES 14 through 16, no further description should be necessary in connection with FIGURES 17 to 20, which merely illustrate the utility of the prefabricated gate panel 86 in conjunction With the other prefabricated panels, posts and attaching means, all previously described.

FIGURES 21 through 23, like FIGURES 17-20, show a further embodiment of the invention, wherein the same gate panel 86 is utilized in conjunction With prefabricated panels 104 and 105, made in accordance with the description relative to FIGURES 5 through 13. The same corner post 47 and associated elements and end posts 48 and associated elements are employed, and no further detailed description is 'believed to be necessary in connection with FIGURES 21-23, which merely show a further use of the gate panel S6, generally in accordance with the description in FIGURES 17 through 20.

Referring once again to the constructions in FIGURES 5 through 13, which are basic to the invention, except for the modifications of FIGURES 14 through 16 and 1-4, it is desired to point out and emphasize that only certain preferred uses of the prefabricated panels and their supporting posts and clamping or attaching means have been illustrated in the drawings and described in the specification. It is also contemplated to use the prefabricated panels, lsuch as panels 44, 45 or 46, in conjunction with the post and attaching or clamp means shown in FIGURES 5 through 13 for erecting the walls of readily dismantlable buildings of various types.

Toward this end, it is desired to point out in connection with FIGURES 5 through 13 that a plurality of the prefabricated panels 44, 4S or 46 may be stacked vertically in edge-to-edge and side-by-side Vertical relation, in conjunction with the same post and clamping or attaching means, shown 'in detail in FIGURES 10-12, for making the side walls of a building. To effect this, the posts 47 and 48 need yonly be made long enough to accommodate `a plurality of the preiabricated panels stacked on edge vertically, and a correspondingly increased number of the clamping or attaching means shown in FIGURES 10 through 12 are also employed.

While I have shown and described sheet metal panel elements 25 provided with oppositely offset rectangular corrugations land being formed of la single section of sheet metal within a rigid frame, I wish to point out that it is within the scope of the invention to make the panel elements -flat or uncorrugated Iand in one piece with suitable flanges formed at ltheir opposite ends for attachment to the metal posts. I also contemplate making the panel elements 25 from a plurality of separately 4formed interconnected panel sections which may be either flat or corrugated and designed for attachment to the posts.

It is to be understood -that the forms of the invention herewith shown and described are to be taken yas preferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the subjoined claims.
