. The general purpose of the invention is to provide an improved sectional metal partition economical to manufacture and capable of easy and effective installation, the parts fitting neatly and the completed installation having the appearance of paneled woodwork.
More particularly the invention has for its objects the provision of improved posts from all sides of which partitions may be extended and between which the sections of the partition are secured; panel members and clips therefor for use on the exposed sides of said posts; cross-bars cooperating with said posts to define frames in which metal or glass panels, transoms, doors and the like are easily and quickly installed and from which the same can be readily removed, together with improved parts for securing the panels, transoms and doors in place; base and top trim members capable of easy installation and removal; an improved door construction; and improved ceiling and wall fect fitting in a partition.
The foregoing and other objects of the invention are attained in the metal partition constructions illustrated in the accompanying drawings and described below. It is to be understood that the invention is not limited to the specific forms thereof shown and described.

Referringto the drawings, the numerals 10, 10 designate posts or uprights by which the partition'is supported. 7 These posts are preferably formed in halves ofsheet metal strips shaped in section asshown and secured together as by spot welding cooperatingoutwardly bentflanges 11, 11 thereon. The posts 10 are generally square in section and are formed with vertical grooves 12, 12, 100 one on each face thereof, the flanges 11 fallsection on line 1313 of 7 ing within certain of these grooves so as not to interfere with assembling of a partition and so as to be concealed when a partition is constructed.
The bottoms of the post may be arranged to be secured to the floor by means of angle brackets 13 (Fig. 4) secured as by screws 14, 14 in grooves 12 and secured to the floor as by screws 15, the angle brackets 13 lying wholly within grooves 12 so as to be concealed when a partition is completed. Apertures 16,16 may also be provided in the inner walls of the grooves 12 adjacent the bottoms of the posts to permit bringing electric wiring into or through the partition.
Arranged for cooperation with spaced posts 10 are transverse base bars17, 17 (Fig ure 9) which are provided at each end with clips 18, 18 secured to the end thereof as shown in Figure 9 and also as shown where the same clips are used on an intermediate transverse panel or transverse bar in Figure to be described later, clips 18 coopcrating with clips 19 secured on posts 10 as shown in Figures 9, 14 and 15, the clips 18 and 19 interengaging to support the transverse base bar and upper transom or'panel bars all in the same manner.
The base bar 17 is preferably formed in halves comprising strips of sheet metal of the section shown with the halves formed with cooperating flanges at 20 secured together preferably by spot welding. The upper side of the bar 17 is provided with a groove 21 corresponding to and cooperating with grooves 12 in posts 10 as will be explained and flanges 20 fall within this groove in a manner similar to flanges 11 in grooves 12 of posts 10. V
The bottom edges of the bars 17 are formed with outwardl and upwardly turned flanges 22, 22 and base strips 23 of sheet metal suitably formed to simulate the usual wooden base board of a room are provided with inwardly turned, downwardly bent flanges 24 for hooking over flanges 22 to secure said base board strips to the base bar 17. The base board strips 23 may be formed at their bottoms with inwardly bent portions '25.
thereon from which extend downwardly bent flanges 26, 26. A channel strip 27 is fitt d between the bottoms of posts 10 and may be secured to the floor by screws 27, 27. This channel strip has upwardly bent flanges 28, 28 thereon to which flanges 26 may be secured as by screws 29, 29., This construction permits the use of molding strips 30, 30 which may be flat as shown or of any desired'ornamental form so as to conceal the fastenings of the base board strips 23 to the channels 27 and to simulate the usual wood molding at the oint of base board and floor of a room. v a
The intermediate panel or transom bars which are indicated by the numeral 31 are shown in section in Figure 10 and are formed in halves of sheet metal strips similar to posts 10 and similarly secured as by flanges 32 spot welded together. The transom bars 31 are formed with grooves 33, 33 in the upper and lower surfaces thereof corresponding to and cooperating with grooves 12 in posts 10 and flanges 32 are located in these 'rooves as shown. The side walls of the panel or transom bars 31 are formed with slightly depressed grooves 34, 34 in simulation of wood paneling. These bars are supported at the desired height between posts 10 by clips 18 and19 (Figures 9, 14 and 15) as has been explained with reference to the base vbars 17.
Top transverse bars are shown at 35, 35 and the construction thereof will be apparent from the sectional views thereof in Figures 11 and 12. These are preferably formed in one piece strips of the sectional shape shown which may be made up to fit various partitions with mitered corner pieces, etc., and formed with a groove 36 in the under side thereof corresponding to and cooperating with grooves 12 in posts 10. These bars usually are extended over a number of posts in continuous lengths and the joints therein secured as by welding or the like.
The bars 35 may be arranged to support top molding strips 37 37 as by the provision of punched out lugs 38, 38 downwardly bent under which may be hooked an upturned flange 39 on the bottom of a strip 37 and by the provision of clips 40 pivoted at 41 adjacent the upper edges of bars 35 and having forked formations 42 on the ends thereof for engaging under and embracing a downwardly turned flange 43 on the upper edge of each strip 37. TV here the sections of strips 37 abut joint covering strips 37 shaped to lit the strips 37 are provided to be pla ed thereover.
As shown in Figure 12, bars 35 are adapted to be secured upon the tops of posts 10, the latter having plates 44 secured in the tops thereof, tabs 45, 45 on said plates preferably being spot welded to the inner walls of posts 10 (see Figure 13) and said plates having threaded apertures 46 to receive screws 47 extended down through the bridge members 48 and the wall of bar 35. The bridge memhere 48 extend into the lower corners of the inside of bars 35 and serve to hold said bars snugly against the posts 10. The bars 35 are open at their upper sides and are formed with inwardly bent flanges 49, 49 to support the ceiling fillers as will be later described.
It will be seen from the foregoing that the posts 10 and bars 17, 31 and 35 when secured together constitute a frame work in which doors, panels. transoms, etc., may be arranged as desired. Figures 1 and 2 show the posts and transverse bars so arranged as to provide a door space and transom space, the base bar 17, of course, not being used in this section of the partition.
The door is indicated by the numeral and it may be constructed with a frame of sheet metal as shown in Figures 5 and 6, the inner perimeter of the frame being formed with flanges 51 along each edge bent inwardly first straight and then convergingly toward each other and then outwardly back upon themselves as at 52 whereby binder strips 53 may be secured on the inner edges of the frame, the strips 53 having inwardly turned flanges 54 extending parallel to flanges 51 in spaced relation therefrom and having reversely bent flange portions 55 for engaging in back of flange portions 52.
The spaces between the flanges 54 of the binder strip 53 and the flanges 51' of the door frame are thus adapted to receive outwardly extending flanges 56, 56 for the door glass or panel supporting frame strips 57, the flanges 56 having nobular formations 56 thereon for snapping into depressions formed in the binder strip flanges 54. The frame ofthe door, of course, is made in sections including the binder and glass frame strips assembled as shown and permanently secured together if desired or necessary. One side of the glass or panel frame 57 is formed with a permanent glass or panel retaining flange portion 57 and the other side thereof is adapted removably to receive a frame portion 57 secured as by screws 57 c to the frame 57. A glass 50 is shown mounted in place in the door.
The door 50 is hinged as at 58, 58 to a jamb strip 59 secured to post 10 by flanges 60, 6O thereon engaged in back of flanges 61, 61 on a clip 62, the latter being fitted in a groove 12 in post 10 and secured therein by screws 63, 63, a jamb strip 64 being similarly secured in the post 10 (Figure 6) at the other side of the door space and a amb strip 65 being similarly secured to the transom bar 31 above the door space, the channel strip therefor (not shown) fitting in the bottom groove 33 of said transom bar.
The transom shown at 66 and the various panels 67 and 68 are all secured in the partition frame in the same way. The manner of securing these transoms and panels in place will be apparent from an inspection of Figures 5, 7, 9, 10 and 11. Each such panel or transom is provided with a frame including a main frame member 69 formed with a permanent panel or glass retaining flange portion 7 0 against which the panel, whether of glass or metal or other material, is clamped by a frame member 72 which may be removably secured to frame 69 by screws 73. The frames 69 may be made in two parts, including filler channel strips 69 secured about the outer edges thereof between flanges 69 69 as by spot welding.
The cooperating grooves in the posts 10, base bars 17, transom or intermediate bars 31 and top bars 35 provide for easy insertion and removal of the various panel or transom sections, the dimensions of the panel and transom frames being such that one side edge of a panel or transom may be inserted angularly into a groove in a post at one side of the panel opening until it engages the back of the groove, whereupon the panel may be swung into alignment with the groove in an opposite post, then elevated into a groove in an upper transverse bar and supported from below as by means mounted on a lower transverse bar (see dotted and full line positions of panel in Figure 1)..
In order to support each panel or transom in place in the partition frame, means are provided as shown in Figures 9 and 10 to support each panel or transom from the bottom. This means may include a strip 74 formed with a molding-like portion 75, said strip adapted to rest on a transverse bar at one side of apanel groove and extending across said groove to the other side thereof, a downwardly turned flange 76 thereon resting against the other side wall of the groove. A panel supporting and locking strip 77 is provided for cooperation with strip 74, the strip 77 being formed with a molding-like portion 78 and being adapted to secure the panel between its molding-like portion 7 8 and the corresponding portion of strip 74 by the pro-vision of at least two supporting and locking plates 79 that are secured to strip 77 and extend laterally therefrom transversely of the strip 74. The plates 79 are provided with respective projecting lips 7 9 for substantially fitting between the downwardly directed flanges of the panel or transom frames, the lower edges of said flanges resting on the upper edges of plates 79 at each side of lip 79 and preferably having notches 80 therein for embracing the supporting plates to hold the panels in the center of their spaces. The plates 79 rest on strip 74. By this construction a panel can only be removed from one side of the partition by lifting it slightly to clear lip 79 and then withdrawing strip 77, as is most clearly shown in Figure 17, the portion 75 of strip 74 preventing removal of the panel from the other side of the partition.
As shown in Figures 1 and 7, the partition may be extended in any direction from a post by the use of angle strips adapted tobe secured to any side of a post 10 as by means of clips 86 formed to lit in a groove 12 and adapted to be secured therein as by screws 87, said clips 86 having flanges 88, 88for engaging about flanges 89, 89 on the angle strips 85 to secure the same between the clips 86 and the post 10. Angle pieces 85 are formed with grooves 90 corresponding to grooves 12 to receive transverse bars, panels, transoms, etc. therein in the same manner as clearly shown in Figure 7.
here a partition ends adjacent a wall less than a standard sectional width therefrom,
4 Those grooves 12 of posts 10 which would be exposed in a completed partition may be fitted with post panel strips 104, 10 i similar to strips 98 and secured in the grooves 12 by clips 96 in the same way as strips 98. These post panel strips are of such dimensions as to be depressed slightly be ow the faces of the post to impart the desired panel effect.
Where completion of a partition to the ceiling is desired, a ceiling filler construction may be employed as shown in Figures 2, 3, 11, 12 and 12. truts 105, 105 of sheet metal preferably of square formation are arranged to be supported on top bar 35 by being provided with shoulders 106, 106 for resting on the top wall of groove 36 of top bar 35 and with opposite flanges 107, 107 for embracing the side walls of groove 36. (Figure 11.) The tops of these struts may have angle plates 108 secured therein through which are threaded screws 109 adapted to be adjusted to provide a determinate thrust in the strut to hold the various parts of the ceiling filler in place. A ceiling filler channel strip 110 is provided to lie against the ceiling being held thereagainst by screws 109 or additional securing means (not shown).
Channel strips 110 are formed with grooves 111 in the under sides thereof in which struts 105 are adapted to extend, screws 109 bearing against the channel in the groove. A channel strip 112 may be secured in groove 111 and provided with flanges 113, 113, providing spaces between the side walls of grooves 111 and the strip 112 to receive the upper edges of the ceiling filler plates 11 1- which are arranged to conceal struts 105 therebetween. The bottom edges of the filler plates 114 may be supported on bridge members 115 removably,mounted on the top flanges 49, 49 of the top bar 35, the plates 114 preferably being secured to the sides of an upwardly projecting formation 116 on bridge members 115 as by means of crews 117, 117. Where the ceiling filler extends to a wall its edges may be secured in the same way as the wall filler panel plates 91" and 91 to a wall channel strip 92. lhe plates 11a of adjoining partition sections may be jointed by means of clip strips 118, 118 (see Figure 12), these being flat sheet metal strips formed with reversely bent flanges 119, 119 to provide grooves in their edges to receive the edges of the filler plates 11%.
[is will ap -ear from Figure 16, the partitions may be constructed in forms in which p rtition. parts are extended from all sides posts 10, panels being shown so extended therefrom in this additional illustration of the manner in which partitions may be constructed from the parts shown.
