"According .to this concept, there is provided one or a pair of sills (depending on-the se'lectedfdesign) which are secured rigidly to the floor of the building, the ends of which abut-the lower end portions-of the 'main frame after the mainframe has been. positioned withinthe door opening. The secondary or door frame is then installed'with, the lower ends of the vertical jambs resting upon the floor and anchored to the'inner endsof the sills, thus'completing theinstallation of the side light frame withintliewallopening. 5 g v A'further ,obj'ectiveof the invention hasbeentoprovide means for connecting the several components of theframe together upon installation in the field in a rapid-convenient;

manner without the use of special tools.

' According to this aspect of the invention, the lower ends of the vertical framing members of the main frame, which'a're' anchored to the wall, each include brackets having ears at their lower ends which interfit the sill, the end of each sill beingsecured to the ears of the main frameby means of screws of the sheet metal-type, passing through the end por-' tion of the sill and through the ears of the-anchor brackets. As

' noted earlier, the sills are anchored rigidly to the floor of the building.

In a similarmanner, the vertical mullions or door jambs of the secondary frame, within which the doors are hung, also havetheir lower ends resting upon the floor and anchored to theinner ends of the sills by brackets and sheet metal screws passing through ears extending from the mullions into the sill.

' SIDE uonr FRAME GENERALLY I The-side lightframe adapts-itself to a number of design variations. For example, the framing .members may be furnishedto provide single or double side'lights with a' single for double door opening. In other instances, the unit may be fumished in single or multiplepanels with no door opening (borrowed light). Still other combinations are available by virtue of the se'ctional construction which imparts design flexi- 'bility. The sectional side light frame assembly is intended par- 7 cross section, arranged to embrace the marginal edge portions of the wall opening on opposite sides, as indicated diagrammatically in FIG. 7. The main frame is completed by a pair of vertical framing members 4 and 5. The framing members 4 section to the header 3. The framing members 4 and 5,,similar to the header 3, embrace the opposite marginal wall surfaces of the opening formed in the wall 1. The header 3 and the framing members 4 and 5 form the basicsectional frame structure which supports the remaining components or dividers of the side light frame, also of sectional construction and of composite design.

J'Ihe mating ends of the header Sand the upper ends of the vertical members 4 and S-are'mitered as'at 6 (FIG. l)to interfit one another upon assembly of the framing members within the wall opening. The mitered ends 6 are held in squared relationship withone another by comerclips'indicated generally at 7 (FIG. 11) which provide a snap fit, rigidly connecting the members together at the corners. A corner clip of this nature is disclosed in US. Pat. No. 3,222,833, issued to Harold L. Woodrum on Dec. 14, 1965, and assigned to the present assignee. A second form of corner clip construction, as shown in the copending application of Harold L. Woodrum, Ser. No. 801,033, also may be used at the corners as an alternate construction.

The vertical members 4 and include adjustable jamb anchors (not shown), located near the upper ends of the mullions. The jamb anchors seat against the vertical studs (not shown) or any other wall surface which delineates the opening and are arranged to force the upper mitered end portions of the vertical members 4 and 5 toward the opposite mitered ends of the horizontal header 3. The anchors also permit the assembled sectional frame structure to be adjusted to a plumb position with reference to the wall opening, thus fixing the main frame 2 in position to act as a support for the other seetional components of the side light frame and the doors which are hung within it. The lower ends of the vertical members 4 and 5 restupon the floor of the building and are anchored to the sills, indicated generally at 8 in FIG. I.

The transom, indicated generally at 10 (FIG. 1), is delineated by a horizontal transom bar ll of composite construction extending transversely between the vertical framing members 4 and 5 and delineating the header of the door opening, which is indicated generally at 12 (FIG. I). In the present example, the structure is arranged to accommodate a pair of doors indicated generally at 13 and 14, which are hung'within the opening, as described later. The door opening 12 is delineated by the transom bar 11 and a pair of door jambs l5 and 16 (FIG. 1 also of composite construction, which extend vertically and in, parallelism with the vertical main framing members 4 and 5.

The door jambs 15 and 16 extend from the floor level, indicated at 17 (FIG. 1) to the horizontal transom bar 11, at which point they are joined to the transom bar 11 as described later. In addition, each door jamb l5 and 16 includes, as a separate piece, an extension projecting upwardly from the transom bar 11 to the header 3 of the main frame 2, as indicated at 18 and 20.

The lower end portions of the vertical framing members 4 and 5 and the door jambs l5 and 16 rest upon the floor l7 and include the transverse sills 8-8, the sills 8 being anchored to the floor 17 as described later.

Installation In installing the side light frame assembly, the sectional main frame 2 is first installed within the opening, followed by the components of the side light frame. Preferably, the header 3 is first installed across the top of the opening and may be held in place by frictional engagement with the opposite marginal surfaces of the wall panels I, as indicated in FIG. 7. After the header 3 is installed, one of the vertical framing members, for example vertical member 4, is pivotally connected to the mitered end 6 of the header 3 (FIG. I), by means of the comer clip 7, the construction of which is described later.

After being pivotally connected, the vertical framing member 4 is pivoted to its vertical position with its limbs frictionally embracing the opposite marginal portions of the wall 1. Thereafter, the second vertical framing member 5, in a similar manner, is pivotally connected to header 3 by means of the comer clip 7 and is swung to its vertical position, also embracing the opposed marginal surfaces of the wall about the door opening. As noted earlier, the framing members 3, 4 and 5 of the main frame, and also the divider components, consisting of the transom bar 11, the door jambs l5 and 16 and the jamb extension pieces 18 and 20 are all basically of the same U-shaped configuration in cross section, with telescopically interfitted rails to complete the structure, as explained later.

After the main frame 2 is installed, the composite'transom bar 11 is placed in position transversely between the vertical framing members 4 and 5 (FIG. I). Thereafter, the sills 8-8 may be mounted upon the floor 17, then composite door jambs l5 and 16 may be installed with their lower end portions resting upon the floor 17 and connected to the sills 8-8. The upper ends of the jambs l5 and 16, are connected to the transom bar 11, as described later, after which the vertical jamb extension pieces 18 and 20, also of composite design, are secured in place.

The structural details of the anchorage of the sills 8 to the floor l7 and the devices for connecting the ends of the dividers, consisting of the composite transom bar 1 l, jambs l5 and l6'and jamb extension pieces 18 and 20, simplify the assembly of the frame structure, as described below.

Structural Details As noted earlier, the sectional vertical framing members 4 and 5, and the header 3 of the main frame 2 (FIG. 1) are identical in cross section, each being generally channelshaped in cross section and embracing the opposite marginal portions of the wall I about the door opening. As shown in FIGS. 2 and 6, the framing members 3, 4 and 5 are in the form of sheet metal stampings, each member being of the double rabbet-type, including the stop 21, delineating the rabbets 22-22 FIGS. 2 and 7). The rabbets 22-22 each include a yieldable limb 23, completing the channel-shaped cross section, and each limb 23 includes an in-turned flange 24 which seats against the opposed surfaces of the wall 1.

Corner Clip As indicated earlier at 7 (FIG. 11), the corner clips 7-7 are of the snap on-type as disclosed in the earlier Woodrum Patent No. 3,222,833.

The upper ends of the vertical framing members 4 and 5 are pivotally connected to the header 3 by means of a tongue (not shown) which interfits a slot formed in the end portion of the header. During installation of the framing members, the header 3 preferably is located across the top of the opening, then the tongues of the vertical framing members 4 and 5 are slipped into the slots of the header to provide a pivotal connection. After the tongues are interfitted with the slots of the header, the vertical framing members 4 and 5 are pivoted, by virtue of the pivotal connection, with reference to the wall opening to their vertical positions to provide the snap connection with the corner clips 7, as described below.

Described generally (FIG. I 1 each corner clip 7 comprises a latch plate or stamping 25 secured preferably by welding to the upper end portion of each jamb. The latch plates 25-25 coact with a pair of keeper plates 26 26, consisting of sheet metal stamping and welded in place at the mitered end portion 6 of the header 3 at opposite ends.

Each latch plate 25 includes a corner portion 27 which projects outwardly beyond the mitered end 6 of the jambs on opposite sides. The comer portions 27-27 act as pivots or guides to align the latch plates (and jambs) with the keeper plates 26 so as to bring the jambs and header into precise alignment as the vertical framing members 4 and 5 are pivoted to their final vertical position within the wall opening.

A latching detent 28 forms a partof each corner portion 27 of the latch plate 25, each detent 28 including a curved section- 30 providing a camming action. In order to provide the snap-in action, each keeper plate 26 includes a yieldable keeper arm 31 which is spaced from the limb 23 of the header 3 at opposite sides. The keeper plate 26 includes an open slot 32 to receive the latching detent 28 to provide the snap-in connection at the mitered corner 6 of the frame members.

In connecting the framing members 3, 4 and 5 (after the tongue engages the slots to provide the pivot connector) the comer portion 27 first enters the space between the limbs 23 and keeper anns 31, thereby to provide a pilot action to align the members. As the pivotal motion continues, the inclined camming section 30 of the latching detents 28 engage the free end portions of the keeper arms 31, then snap into engagement within' the open slots 32 of the keeper arms, thus completing the corner connection.

' v After the vertical framing nel-shaped in cross section, comprising a baseplate'35 secured to the floor and having vertical limbs 36-36 rising'from the base. The upper ends of the limbs 36 include angulated upper end portions 37 which provide a camming action with reference to the'sill8. I A 1 a J Generally speaking, the sill 8 is of a two-PIECE construction (FIGS. and 9) consisting of the section 38 and a companion section 40. The sill section 38 includes a stop 41 corresponding to the stop 21: previously described with reference to the framing members 3, 4 and 5. The stop 41 includes a lip 42 overlying an angular section 43, the two parts interfltting one another. The two sections are secured together by screws, as described later. I

After assembly of the vertical framing members 4 and 5 and Q the header 3, with the mitered joints 6 joined by .the corner clip 7, the sills are anchored tothe floor by clamping engagement withthe baseplates 35-35 on opposite sides of the opening. The endsof the sill 8-8are'then secured to the lower ends of the vertical framing members 4 and 5,- thus securing the main framepermane'ntly in position within the wall openmg.

' Sill Connection Details I After the main framing members 3, 4 and 5 have been-installed in the opening, as described above, each sill 8 is installed upon the floor 17 to anchor. the lower ends of the framing members in position with reference to the wall opening.

The end of each sill 8 is anchored to the vertical framing members and'S after they have been installed with the wall opening. Described with reference to the left-hand sill (FIG. 9) the sill 8 is anchored to the lower end portion of the vertical framing member 4 by means of a pair of brackets 44-44 secured to the rabbets 22 of the vertical framing members, in' this case the left band member Each bracket 44 includes ears 45-45 at its upper andlower ends and is reinforced by a side flange 46. The composite sill 8:includes holes 47 and the ears 45 include'holes 48 which match with the holes 47 when the sill is installed with respect tothe vertical member 4. With the sill in position, screws 50, preferably of the sheet metal-type, arethreaded through the matching holes 47 and 48, thus anchoring the sill 8to the vertical member 4.

The sidewalls of the sill sections 38 and 40 also include holes 47 which match the holes 48'formed in the side flanges 46 of bracket 44 (FIG. 9). Screws 50 are threaded through the matching holes at assembly. A similar construction is utilized in'anchoring the right-hand sill 8-to the vertical member 5. It will be noted that the end portionof the sill 8, which abuts the stop 2l of the vertical member 4 or 5.

Transom Bar v 6 Door Jamb Connection As noted earlier, the lower ends of the door jambs 15 and 16, which delineate the door opening, rest upon the floor l7 and are anchored to sills 8-8 in the same manner as described earlier and shown in FIG. 9 by means of the brackets 44'and the self-threading sheet metal screws 50. Y The upper end portion ol each door jamb 15 and 16 is connected to the transom bar 11 by means of .the U-shaped brackets 6l-61 (FIG. 10). In this case, identical U-shaped brackets 61 are secured to the upper surface (rabbets 22) of the transom bar 11 tomake the connection with the jamb extension pieces 18 and 20. In a similar manner self-threading sheet metalscrews are threaded in place through the vertical'door jambs members 15 and 16 and through the apertures 62 of the mounting brackets 61. I

The upper ends of the vjamb extensions 18 and 20 are secured to the header 3 of the main frame 2 by the use of similar mounting brackets 6l-61welded to the header 3 and secured in place by sheet metal screws 50, as described below.

Jamb Members As best shown in FIG. 4,,the door jambs l5 and 16 (shown generally in FIG. 1) are of composite construction, similar to the. transom bar 11, asdescribed above. the jamb extensions, previously indicated at 18 and 20 (FIG. 1) are of similar construction in cross section.

The extension pieces 18 and20 are also of composite construction, each consisting of a main channel-shaped member 63 (FIGS. 4 and'6), each member having a mullion section 64'.

Tocomplete the jambs and the extension pieces, and to provide a symmetrical structure, each main channel member 63 (FIG. 4) includes'an internal insert bar 65, formed of sheet metal, and generally channel-shaped in cross section. The insert bar 65 includes outwardly projecting flanges 66.

As described abovewith reference to the transom bar 11, the composite jambs l5 and 16 and their extensions 18 and 20 each include'amullion section 67, also formed of sheet metal including outwardly turned flanges 68 seated against flanges verticalmember (FIG. 9) is inset as at 51 to accommodate the I composite construction consisting basically of a sheet metal channel-shaped member 52 having a series of U-shaped clips 53. In order to complete the transom bar 11 and form a symmetrical structure, the U-shaped clips 53 (FIG.' 3) include flanges 56-56 underlying the flanges 57-57 of the channelshaped transom bar includes an internal insert 58, also channi-shaped v and having flanges 60-60 seated against the flanges 56 of the clips 53. r

In assembling the composite transom bar 11, the insert clips 53 are slipped within the bar 52, and the insert bar 58 is then slipped'in position. Thereafter, the cap 55 is slipped upon the clips 53 to complete the assembly (FIG. 3).

66 of insert bar 65. Assembling the composite jambs, the insert mullions 67 and the internal reinforcing bar 65 are telescopically interfltted and snapped together, thus forming a rigid assembly.

The lower end portion of the assembled jambs 15 and 16 rest upon thefloor l7 and are anchored to the respective sills by means of the brackets and screws 50, as described earlier with reference to FIGQ9. It will be understood that the end'of the sills which abut the jambs 15 and 16 are inset as previously indicated at 51 to accommodate the stop 21.

Transom Bar Connection transom bar 11 is connected to the vertical main framing members 4 and 5 by means of the pairs of brackets 70 which are U-shaped to provide ears 71-71. The brackets are attached to the rabbets 22 on opposite sides of the stop 21.

Upon installation of the transom bar 11, the ends of bar 1] 1 are placed in abutment with respect to the vertical members 4 and 5 such that the walls 72 of thecomposite transom bar 11 register with the ears 71-71 of the mounting brackets 70. With the opposite endsof bar 11 in position, sets. of screws 73, preferably of the self-threading sheet metal-type, are installed within the matching walls and ears, thus securing the horizontal transom bar to the vertical framing members.

Installation The frame structure is furnished to the user as sectional parts-suitably packaged and ready for installation within the door opening of the wall 1, the door opening having been delineated by suitable vertical studs and a horizontal header (not shown). Preferable the composite framing members, that is the door jambs l and 16, the vertical extension pieces 18 and 20, and the composite transom bar 11 are assembled at the manufacturing plant. However, these members can be assembled at the building site if desired or necessary.

At installation in the field, the main frame 2 is first installed within the opening of the wall 1 preferably by placing horizontal header 3 in position and pivoting the vertical framing members about the header by operation of the comer clips 7, as described earlier. After the main framing members 4 and S are joined to the opposite ends of the header (mitered joints 6 FIG. 1) the remaining components of the frame, consisting of vertical door jambs l5 and 16, as described earlier, the lower ends of the jambs and 16 are anchored to the sills 88 (previously installed). The transom bar 11 which extends across the entire frame between the vertical framing members 4 and 5 is then installed across the upper ends of the jambs l5 and 16, and the parts are secured together by the sheet metal screws 50, as described earlier.

After the main frame 2 and the inner frame have been installed within the opening, the transom panels 54 and the side light panels 54 are installed within the frame. It will be noted that the panels are seated against the stop sections 21 of the mullions and secured by retainer strips 74 engaging the surface of the panels and being secured in place by the screws 50.

Referring to FIGS. 1 and 6, the frame structure is provided with a pair of doors indicated at 13 and 14. A suitable lock (not shown) secures the doors in closed position when not in use. The doors l3 and 14 (FIG. 6) are hung within the jambs l5 and 16 by means of hinges 75 of conventional design, the hinges being secured to rabbet section 22 of the jambs l5 and 16.
