` (c1. iss-75) 3 Claims.

The invention relates to casing constructions and refers more particularly to metal window casing constructions for use especially in buildmgs.

The invention has for one object to provide a casing construction which can be readily attached to a window frame when the latter is mounted in a wall.

'I'he invention has for another object to provide a casing construction which isattachable as a unit toawindow frame. v Y

The invention has for a further object to provide a casing construction in which the casing sections are secured to their respective frame bars by snap engagement.

These and other objects of the invention will become apparent fromthe following description, taken in connection with the 'accompanying drawings, in which Figure 1 is an inside elevation, partly broken away, of a window frame and casing assembly embodying the invention; s

Figure 2` is a vertical section through a building wall illustrating the method of attaching the casing to the window frame;

Figures 3, 4, and 5 are, respectively, head, jamb and sill sections illustrating the complete assembly;

Figure 6 is a view similar to a portion of Figure 2 and illustrating a modied construction;

Figure '7 is a plan view thereof;

Figure 8 is a view showing the. parts attached;

Figure 9 is a View similar to Figure `8 and illustrating a modified construction;

Figure 10 is a plan View thereof;

Figures 11 and 12, Figures 13 and 14, Figures 15 and 16 and Figures 17 and 18 are views similar to Figures 9 and 10, respectively, and illustrating modified constructions; v

Figures 19, 20, 21, 22, 23 and 24 are views similar to Figure 8 and illustrating modied constructions.

As illustrated in Figures 1, 2, 3, 4 and 5, l is a metal window frame of standard construction having its sides formed of the relatively narrow bars 2 which are welded or otherwise secured to each other at the corners to form a rigid structure. In the present instance, the bars are of a Z cross section having the outside and inside

flanges

3 and 4 respectively, the intermediate web 5 and the beads 6 and 'I on opposite sides of the web from the outside flanges `and 4inside flanges respectively. The window frame is adapted to be anchored in the wall of the building through the outside flanges and occupies only a fraction of the width of the wall.

The casing construction supplements the window frame and has a width corresponding to the distance from `the window frame to the inside of theA wall in which the window frame andV casing construction are' mounted; The casing construction is formed of the sheet metal sections 8, 9, IIJ and Il which correspondrespectively to the several bars forming the head, sill and jambs of the window frame. The sections have at their inside edges the plaster ground and trim flange I2. The sections also have their ends fashioned forinterengagement with; each other, the upper and lower sections '8 and .il-being formed at their ends with the flanges I3 for overlapping the upper and lower end portions ofthe jamb sections I0 and Il and the jamb sections being provided withthe tongues I4 which Aare bent over the end portions of the upper and lower sections, thereby locking all of the sections together. The tongues may be either integral withthe jamb sections or permanently attached thereto, as `by riveting, welding, or other method.

The casing is attachable as a unit to the window frame when the latter is mounted in the wall. Thus, while the several sections of the casing may be shipped knocked down to occupy a minimum amount of space during transportation, the sections may be quickly assembled with each other at the point of erection to form the casing unit which may then be installedand attached to the window frame which has been previously mounted in the wall. The attachment is accomplished by movement of the casing unit transversely of the window frame. For interlocking the casing unit tothe window frame cooperating shoulders are provided on each of the casing sections and window frame bars for limiting relative transverse 'movement thereof and also snap `engagement is provided between each of the casing sections and the window frame bars, as illustrated in the present instance. In detail, each of the casing sections 8, 9, I0 and I I has its outside marginal portion formed with the transversely extending portion I5 which provides a shoulder for engaging and cooperating with the shoulder formed by the inside face of the inside bead 'I of the associated window frame bar to limit transverse movement of the section relative to the window frame bar in an outward direction.V The offset portion I B of each section is adapted to pass over the end of the inside bead 'I and is formed with the plurality of longitudinally extending elongated openings Il. Y

I8 are resilient sheet metal clips each having the foot flange I9 xedly secured to the outside flange 3 of each window frame bar, as by riveting, welding, or other means, and having a body extending substantially parallel, but spaced from the web of the bar so that the oifset portion of the associated casing section may pass under the body. The clips correspond in number to the openings I1 and are located so that the tongues 20, one of which is struck out from the body of each clip, may extend intoan opening. The tongues are inclined toward the web of the associated bar and also toward the outside so that when the casing is being inserted the casing sections flex the clips while riding past the tongues until the tongues snap into the openings. The free ends of the clip bodies are preferably inclined away from the webs to facilitate installation of the casing. At this time the ends of the tongues form shoulders which engage and coupe-rate with the shoulders formed by the outside edges of the openings to limit transverse movement of the casing sections relative to the frame bars in an inward direction and the transverse portions I of the sections being engageable with the inside beads 1 to limit transverse movement in the opposite direction. After the casing has been installed, the inside face of the wall may then be finished by plaster which anchors on the anges I2 of the casing sections. i

Figures 6, '7 and 8 illustrate a modified construction which diiers essentially from that of Figures 1 to 5 inclusive in that the resilient sheet metal clips 2| are U-shaped and have the side flanges 22 flxedly secured to the webs 23 of the window frame bars as by riveting, welding, or other means. The opposite side flanges or body portions 24 of the clips are formed with the transverse elongated openings 25 into which the tongues 26 upon the casing sections are adapted to snap. These tongues are struck out from the offset portions 21 at the outer marginal edges of the casing sections and` are inclined away from the webs 23 and toward the inside. As a result, the ends of the tongues form shoulders adapted to engage and cooperate with the shoulders formed by the inside edges of the openings to limit transverse movement of the casing sections relative to the window frame bars in an inward direction. Relative transverse movement in an outward direction is limited by the transverse portions 28 upon the casing sections engageable with the inside beads 29 of the frame bars.

Figures 9 and 10 illustrate another modification in which each casing section 30 has the longitudinally extending transverse portion 3I for engaging the inside bead 32 of the associated window frame bar 33 and also has the offset marginal portion 34 which is formed with the elongated openings 35 extending longitudinally of the casing section. 36 are resilient sheet metal clips which are generally U-shaped, each having the side flange 31 rigidly secured at its ends as by riveting, welding, or other method, to the web 38 of the bar. The flange 31 is provided intermediate its ends with the boss 39 which enters the circular opening 40 in the web. As a result, each clip is accurately positioned on the frame bar. The opposite side flange 4I of each clip has struck out therefrom the tongue 42 which is inclined toward the web and toward the outside and has its end engageable with the outside edge of the adjacent opening 35. The free end `portion of the outside flange is inclined or .flared to facilitate entrance of the casing section.

In the modication disclosed in Figures 11 and 12, the casing unit is formed of the casing sections 43, each having the longitudinally extending transverse portion 44 for engaging the inside face of the inside bead 45 of the associated window frame bar 46. The offset portion 41 of the casing section is formed With the return-bent iiange 48, the end of which is engageable with the end of the tongue 49 depressed from the free end portion of the side flange 50 of the resilient U-shaped sheet metal clip 5I. The opposite side ange 52 of the clip is formed with the tubular portion 53 which is adapted to extend into the circular hole 54 in the web of the frame bar. 55 is a suitable rivet passing through the tubular portion and iixedly securing the clip to the frame bar, the iiange 50 being formed with the opening 56 to permit access to the rivet to head the same.

In the modified construction disclosed in Figures 13 and 14, the resilient sheet metal clips 51 are U-shaped and each is formed with the tubular portion 58 extending into the circular opening 59 in the web of the frame bar and xedly secured thereto as by the rivet 60. The spaced flange 6I is formed with the opening 62 permitting access to the rivet and with the flared free end portion to facilitate installation of the casing unit. I'he casing unit is formed of the casing sections 63, each of which has the longitudinally extending transverse portion B4 for engaging the inside bead 65 of the associated frame bar. Each casing section also has the offset portion 66 which is adapted to extend between the inside bead and the spaced side ange of the clip and which is formed with the struck out tongues 61 inclined toward and engageable with the outside face of the inside bead. In this construction, the two faces of the inside bead of each window frame bar function to limit transverse movement of the associated casing section in opposite directions.

In the construction illustrated in Figures l5 and 16, 68 is one of a plurality of resilient generally U-shaped sheet metal clips having the base side ilange 69 formed with the tubular portion 10 extending into the circular opening 1I in the web of the bar and riveted thereto. The opposite flange of the clip is formed with the flared portion I2 to facilitate installation of the associated casing section and also with the opening 13 to permit access to the rivet. Thecasing section I4 is formed with the longitudinally extending transverse portion 15 engageable with the inside face of the inside bead 16 of the frame bar and the offset portion 11 of the casing section is formed with the openings 1B, the outside edges of which are engaged by the free ends of the tongues 19 formed upon the base portions 69 and extending outwardly. During the installation of the casing unit, it will be seen that the offset portions of the casing sections flex the spaced flanges of the clips and also flex about the transverse portions of the casing sections until the tongues 19 register with the openings 18, when the offset portions of the casing sections will be resiliently urged toward the webs of the associated bars to engage the tongues in the openings.

Figures 1'1 and 18 disclose another modified construction in which the resilient sheet metal clips are generally U-shaped and have their base side flanges 8l fixedly secured to the web of the associated window frame bar as by rivet. ing, Welding, or other method. The opposite side flange 82 is formed at its free edge with the return-bent portion 83 which assists inv guiding the oiset portion 84 of the casing section 85. The offset portion is formed with the elongated openings 86 which are engageable by the tongues 8l' formed 4upon the free ends of .the base anges 8|. This structure is installed in much the same manner` as that illustrated in Figures 15 and 16.

The modied constructions disclosed in Figures 19 to 24 inclusive have Window frames in which the bars are of special cross section. In the structures disclosed in Figures 19 to 22inclusive thecasings are attachable as units to the Window frames, While in the constructions illustrated in Figures 23 and 24 the casings are attachable-,to the Window frames by attaching the casing sections forming the casings individually to their respective window frame bars. Y

Referring to the structure of Figure 19, 88 is one of the casing sections of the casing unit having at its outer edge the V-shaped portion 89 which is adapted to engage a correspondingly shaped portion formed upon the associated window frame bar 8B by the inside flange 9| and the oppositely extending inside bead 92. The casing unit has a snap engagement with the Window frame, the bars of the latter having permanently secured to their webs the resilient clips 93 Which have at their free ends the transverse portions or tongues 94 Which overlie the terminal edges of the V-shaped portions 89 and prevent accidental disengagement of the casing unit from the Window frame.

As shown in Figure 20, each of the casing sections 95 are formed at their outside edges with the transverse flanges 88 and each of the Window frame bars 97 is formed with a rabbet which is produced by the inside ilange 98 and the inside bead 98, the latter being offset outwardly relative to the former. |80 is one of the resilient sheet metal clips xedly secured to the Webs of the window frame -bars and having at its free end the sheared out tongue the end of which is engageable with the inside face of the flange @6. As a result, each of the casing sections of the casing unit is held from transverse movement in either direction relative to the associated Window frame bar.

As shown in Figure 21, the bars |02 of the window frame are of Z section but the face of the web |93 of each bar opposite the inside flange is in the one plane. Each of the ycasing sections |04 of the casing unit are adapted to slide over this face of the Web and have at their outside edges the return-bent portion |05, the free end of which is engageable With the tongues |86 struck out from the resilient sheet metal clips |61 Which have their bases fixedly secured to the Web by suitable means, such as riveting, Welding, or other method. The other end of the return-bent portion is engageable With the transverse portion |88.

The bars forming the Window frame illustrated in Figure 22 are formed in the same manner as the bars |82 of Figure 21. The casing sections |89 of the casing unit are each provided with the sheet metal resilient clips H0 xedly secured at one end to the outer edge of the casing section. Each of these clips is formed With the struck out tongue Which, after the casing unit has been installed, has its free end engageable with the outside edge ||2 of the stop |13 fixedly secured to the adjacentvveb of the windowframe bar. The outerend of each .of the resilient clips is engageable AWit-hr thel adjacent outside `flange of the frame bar, theconstruction .being such that movementof each of the casing sections transversely of itsassociated Window frame bar in opposite directions is limited. i Y.

As disclosed in. Figure 23, each of the Window frame bars is of general Z' section having the outside and insideangesl I4 and ||5, respectively, the .connecting Web |||,V the bead extending away from -the outsideffl'ange, and the bead ||8 extending atlan angle lavvay from the insidebead ||5rand inwardly.' Each of the casing sections |9 isindividually attachable'ito its vassociated framebar and each casingrs'ection has at its outside marginal edge thevshaped portion 20, one part of which extends parallel to and engages the outside face of the inside beadA I8 and the other part of Which extends substantially at right anglesl thereto. Substantially.- U-shaped resilient sheet metal clips |2| have their `base side anges rigidly secured to the web ||6 and have the struck out tongues |22 and |23 struck out from the spaced side flanges and engageable with the terminal part of the V-shaped portion at opposite sides thereof.

As illustrated in Figure 24, each of the Window frame bars |24 is of general Z section and has opposite the inside flange the longitudinally extending V-.shaped recess |25, the Walls of Which 4associated frame bar, this also being true of the other casing sections.

In the structures of both Figures 23 and 24, the casing sections after being individually engaged with their respective frame Ibars are secured to each other at their ends preferably in the same manner as illustrated in Figure 1.
