Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     An assembly of mating components of a two sided door of colonial grid means which reduces assembly cost and provides a closure, such as a door with an authentic colonial grid appearance. 
     2. Description of the Prior Art 
     Closures, in the form of both doors and windows often incorporate a popular design commonly referred to as a colonial grid. Typically, such a structural configuration is defined by a plurality of panes of glass of substantially equal dimension and configuration surrounded by an outer peripheral frame and/or a plurality of vertical and horizontal muntin bars. While clearly such a structure is aesthetically pleasing, the production and/or assembly of a true colonial grid structure is time consuming and accordingly, very expensive. 
     Attempts of course have been made in the prior art to simplify construction or assembly techniques in the production of doors or like closures incorporating a colonial grid appearance. To date, there still appears to be a need for an improved assembly of components for the same and production techniques. This is especially true when modern day production facilities are available which are capable of producing a door with an aluminum or like material framing structure capable of resembling a number of contemporary and traditional colonial designs. 
     SUMMARY OF THE INVENTION 
     The present invention relates to an assembly of components, which is a two sided colonial grid assembly into a door or like closure assembly. 
     The colonial grid assembly includes a peripherally disposed support frame, or frame portion, including a) head and sill members disposed respectively at the top and bottom of the frame, as well as b) jamb members disposed along the longitudinal frame sides and further disposed in interconnecting relation between the head and sill portions of the supporting frame, the support frame being disposed in a horizontal attitude for assembly of the components described herein. The frame is formed from an extruded aluminum material and is specifically configured for mating attachment to the following components of the assembly. 
     Such other components include an attachment bar, preferably aluminum, secured to a track in the inner peripheral edge of the above-noted members of the frame portion. Such attachment bars are structurally configured to include an integrally formed facing extending along the length thereof and disposed in engaging relation with correspondingly positioned glass panes of which the subject closure structure, such as a door, is formed. Further, each of the attachment bars are structurally configured to receive a correspondingly positioned peripheral edge of the glass panes and further structured to also receive a glazing bead, preferably roll formed of aluminum material and itself being structured to snap-fit into engagement in the receiving channel in engaging relation with an opposite side of the glass pane relative to the integral formed bead. 
     Another component of the subject colonial grid assembly comprises the provision of true muntin bars extending transversely in spaced apart parallel relation to one another along the length of the closure wherein each true muntin bar includes a facing portion and an outwardly extending transversely oriented mounting web. The facing portion is disposed on one of two opposite sides of the assembled glass panes wherein the mounting web is of sufficient length to extend between adjacently positioned glass panes and extend outwardly therefrom to an opposite side of the glass panes relative to the facing portion. The protruding portion of the mounting web also defines receiving channels on opposite sides thereof. Each of these receiving channels is also configured to receive a formed aluminum material glazing bead in snap-fitted engagement with the web and the correspondingly positioned and received supported glass pane. 
     The assembly of the two sided colonial grid assembly is essentially completed through the provision of false muntin bars externally configured in a substantially equivalent appearance as the facing portions of the true muntin bars. The false muntin bars are disposed in perpendicular relation to the facing portions of the adjacent true muntin bars and in spaced apart parallel relation to one another. The resulting product of the assembled components has the appearance of a true colonial grid assembly wherein a plurality of elongated glass panes are effectively divided, at least in appearance, by surrounding framing portions on both of two opposite surfaces thereof. In inter-fitting and cooperative structure of the true muntin bars, false muntin bars and glazing beads along with the attachment bars secured to the peripheral frame serve to facilitate ease of assembly and reduce the cost of production. 
     The structure and configuration of the components facilitate ease of assembly and the reduction of cost because the frame is formed of the interconnected header joints and sill members and almost all of the components interconnected on a worktable while remaining flat. 
     It will be appreciated that the divisions of glass by the true and false muntins result in a colonial grid appearance. However, the actual number of pieces of tempered glass are substantially reduced. For example, in the embodiment shown in FIG. 1 and to be described in greater detail hereinafter, fifteen panels or light zones are in reality only five elongated laterally extending co-planar panels separated by the false muntin bars yielding the colonial grid appearance. This achieves a substantial labor cost reduction and in many cases makes certain jobs possible because in the past, tempered glass has been limited to certain size areas because of cost of manufacture and techniques commercially used in the window art.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A closure assembly such as a door or the like incorporating the two sided colonial grid assembly of the present invention is shown in FIG. 1 and generally represented as 10. 
     Before describing the structure and configuration of each of the components of the colonial grid assembly, it may be helpful to describe, first, their relationships in assembly and the actual assembly of them. The components include: a) peripheral frame members, jambs 18 and 20, and header and sill members 14 and 16, which are seen in cross-section in FIG. 6; b) peripheral attachment bars 24, shown in cross-section in FIG. 5, one of which is received in the track opening 22, see FIG. 6, of the jamb header and sill respectively; and c) true muntin bars, 30, seen in cross-section in FIG. 4 which laterally span the peripheral attachment bars received in the track openings 22 of the jambs, see the plan view of FIG. 1. 
     After these three types of components have been connected together in a flat assembly on a work surface, a first plurality of false muntin bars are connected between the true muntins and attachment bars on the header and sill. Then, d) glass panes 26 are positioned supportingly on co-planar surfaces defined by support surfaces of the attachment bars 24 and true muntins 30. Each of the panes extend between the jambs in parallel spaced co-planar relation, the web of the true muntins being between adjacent panes. Before the panes 26 have been positioned on the assembly, e) the plurality of spaced false muntin bars 40 vertically span the laterally extending true muntin bars 30 separating the appearance of the panes into a colonial grid. When this assembly has been secured together, a second plurality of additional lengths of false muntin bars are applied to the opposite glass surfaces of the glass panes, see 40 in FIG. 7. Finally, glazing strips 50, seen in cross-section in FIG. 2, see also FIG. 11, are &#34;popped&#34; into the assembly along each of the peripheral laterally extending edges of the glass panes, the glazing strips being secured to the attachment bars 24, as seen in FIG. 7 at the lower right hand corner, as designed by the numeral 50 and in FIG. 8. The components of the assembly are thus seen to be interconnected in a relatively inexpensive assembly process which provides a strong closure composed of the components. 
     Referring to the assembly in more detail, a peripheral frame 12 composed of spaced vertical jambs 18 and 20 are interconnected with a spaced head and sill member 14-16, see FIG. 1. The common cross-section of these members is seen in FIG. 6. Each of these frame members, it seen, has an open track 22, see FIG. 6, which in assembly face inwardly, the jamb tracks confronting one another in spaced relation and the header and sill tracks confronting one another in spaced relation. The peripheral frame 12, when interconnected, is in a flat attitude on a flat work surface, as seen in the plan view in FIG. 1. 
     Into the track 22 of each frame member, a peripheral attachment bar 24 is inserted, see FIG. 5. In other words, the attachment bar of FIG. 5, as seen there in cross-section, is moved to the left into the track or opening 22, as seen in the adjacent FIG. 6. As further seen in the plan view of FIG. 1 of the closure assembly, representing the assembly on a horizontal support surface, four laterally extending spaced true muntin bars 30, seen in cross-section in FIG. 4, are provided in spanning relation of the adjustment bars 24 in the jambs 18 and 20. Surfaces on the frame members 14, 16, 18, and 20, and the true muntin bars 30 define five rectangular openings each bounded by a co-planar peripheral support surface. Next, five laterally extending spaced panes of glass 26, appropriately sized, are positioned in co-planar relation on the support surfaces, each pane spanning the jamb member 18 and 20. Each pane its sized such that is opposing peripheral ends rest on the attachment bars 24 in the space designated by the arrowed line 62 in FIG. 5. The longitudinal peripheral edge of the uppermost and lowermost glass panes, along the header and sill respectively, also rest in the space 62 of the attachment bars in the sill and jamb. While the assembly remains flat and before the glass panes are inserted, a first, plurality of false muntin bars 40 are installed, see FIG. 7 illustrating their attachment to the attachment bars 24 and see FIG. 11 illustrating their attachment to the true muntin bars 30. Thereafter, as demonstrated by the arrowed line 40 in FIG. 7, and a second set of false muntin bars may be applied in confronting relation to the first plurality of false muntin bars already described and resting against the opposite surface of the glass panes. Finally, glazing strips, such as 50, seen in cross-section in FIG. 2, and which are of flexible aluminum material, are &#34;popped&#34; into position as designated by the arrowed line 50 at the upper portion of FIG. 8. There is thus assembled a two sided closure, with a colonial grid appearance, such as a door or window. The components will now be further described. 
     The door is defined by a peripheral frame generally indicated as 12. The peripheral frame 12 comprises a plurality of interconnected components including a head portion 14, a sill portion 16 and oppositely disposed elongated jamb portions 18 and 20. The head and sill, 14 and 16 respectively, are shown in cross-section in FIG. 6 and include one open elongated side or track, generally indicated as 22, see FIG. 6. This track is structured to receive a peripheral attachment bar 24, to be described in the following paragraph with reference to FIGS. 5, 7 and 10. 
     The attachment bars 24 have an elongated configuration and extend along and partially within the inner longitudinal side opening tracks 22 of the head 14, sill 16 and jambs 18 and 20 and in receiving, supporting engagement with correspondingly positioned edges of the plurality of glass or like material panes 26, see FIG. 7. 
     Each of the glass panes 26 have an elongated configuration and extend in substantially parallel co-planar and adjacent or spaced relation to one another transversely across the closure structure 10 as in the preferred embodiment seen in plan in FIG. 1. It should be apparent therefore that the elongated panes 26 have their opposite peripheral ends supported to the jambs 18 and 20 by virtue of their interconnection with correspondingly positioned attachment bars 24. 
     Another component of the subject colonial grid assembly comprise true muntin bars, see FIG. 4, generally indicated as 30. Each true muntin bar 30 includes an outwardly exposing facing portion 32, See FIGS. 4 and 9, and a transverse outwardly extending mounting web 34. The mounting web 34 is integrally secured to the facing portion 32 and has one end, as at 35, secured to the facing portion as shown in FIG. 4 and the web 34 and other end 37 extend through, that is between the, adjacently positioned edges of glass panes 26 and extending outwardly from the opposite side of each such pane relative to the facing portion 32. The true muntin bars 30 extend in spaced, parallel relation to one another and transversely, that is across the length of the closure 10, as shown in FIG. 1. Further, the true muntin bars 30 have their opposite ends 36 and 38, matingly configured and structured to be interconnected to the jamb portions 18 and 20 respectively of the peripheral support frame 12 as best shown in FIG. 1. Other structural features of the true muntin bar 30 as represented in FIGS. 4 and 11 include elongated channels 31 in which caulking or like sealant material is placed for the sealing engagement with correspondingly positioned surfaces of the glass panes 26. In addition, each of the channels 31 are bordered along their length by outwardly extending elongated flanges 3 wherein the flanges 33 extend outwardly in equal distance so as to concurrently engage the corresponding surface of the pane along with the caulking or sealant within the channels 31, this facilitates against leakage or breakage of the glass pane so engaged. Further, the terminal ends of these flanges are co-planar with the support surfaces of the attachment bars and also comprise support surfaces of the glass panes 26. The similar surface included in the attachment bar generally indicated as 24 is designated 33&#39; and shown in detail in FIG. 5. In other words, each attachment bar includes one face 49, see FIG. 5, having on the opposite surface two channels such as 31&#39; in which caulking or like sealant material is supplied for confronting engagement with the corresponding surface of the glass pane 26. Elongated ridges or flanges 33&#39; extend along the length thereof and are co-planar as indicated for stable confronting engagement with the corresponding surface of the pane 26 and for supporting the glass panes in assembly. 
     Another component of the subject assembly includes the false muntin bars 40, seen in cross-section in FIG. 3, which also may be formed from aluminum material. Each of these bars include an outer exposed facing portion 42, 42&#39; substantially identical in appearance to the facing portion 32, 32&#39;, see FIG. 4, of the true muntin bars 30. As shown in FIG. 3, false muntin bars 40 have the co-planar flanges 44 disposed in engaging, confronting relation with the opposite surfaces of the adjacent glass panel 26 respectively and their opposite spaced longitudinal ends structured and configured to matingly and abuttingly connect to either an integrally formed facing 48 on the attachment bar 24, see FIG. 7, or the exposed facing portion 32 on the true muntin bar 30 (see FIG. 9). Also, the opposite ends of each of the false muntin bars 40 may include appropriately curved slots or cut out portions 43 to mate with and receive the curved facing, of the above-noted integral facings or true muntin bars 30 and attachment bars 24 (see FIGS. 7, 10 and 11). This also forms an end on each such bar which is matingly received in companionate notch 61, see FIG. 10 of the attachment bar 24 and the notch 60 of the true muntin bar, see FIG. 11. 
     The final component are glazing beads 50, see FIG. 2. These are preferably roll formed from an aluminum material and specifically structured to have a facing portion 52 substantially identical in configuration and appearance to the facing 48 of the attachment bars 24. In addition, the roll forming of the glazing bead 50 allows it to be flexible to a certain extent. Accordingly, it can be handled or manipulated when the colonial grid assembly is being formed on a work surface or when being installed. The glazing bead 50 further includes a receiving flange as at 54 which is designed to fit beneath and in engagement with a peripheral edge of the pane 26, see FIG. 8, as it is &#34;snap-fitted&#34; in appropriate position in receiving channels formed both on the mounting web of the true muntin bars 30 or the attachment bar 24. With regard to FIG. 4, the first and second receiving channel, generally indicated as 56 and 58 (see FIG. 4), are formed on opposite sides of the mounting web 34 and specifically are cooperatively structured with the placement of the individual panes 26 each to receive one glazing bead 50 therein. With reference to FIG. 8, it is seen that one of the first and second receiving channels, as at 56, on one side of the mounting web 34 is disposed and structured to receive the periphery of the pane 26 in a manner such that the receiving flange 54 of the glazing bead 50 is effectively sandwiched therebeneath. In such a position, the exposed facing portion 52 of the glazing bead is disposed on the opposite surface of the pane 26 relative to the facing portion 32 and is cooperatively configured so as to be similar in appearance. 
     The end portion 37 of the web of the true muntin bars 30 resembles the outermost elongated member 32&#39; on the exposed surface of the facing portion 32 of the true muntin bars 30. In order that both sides of the closure as shown in FIG. 1 appears the same and to have a duplicate colonial grid structure, the false muntin bars 40 also have the elongated surface 42&#39; similar in appearance, configuration, dimension, etc. 
     Placement of first and second glazing beads 50 within the first and second receiving channels 56 and 58 of the real muntin bars will resemble muntin bars on opposite surfaces of the pane 26 as should be apparent with review of FIG. 8. A surface 59 of the glazing beads 50 is disposed in confronting relation with one of the surfaces of the glass pane 26 as also shown in FIG. 8. 
     With reference to FIG. 7, lower right hand portion, a third glazing bead 50&#39; is seen, which is identical in structure, dimension and configuration to the first and second glazing beads, as represented in FIG. 2. It is designed to fit within the third receiving channel 62 of the attachment bar 24, see FIG. 5, and extend along the length thereof. The flange 54 of the respective glazing bead as at 50&#39; will fit beneath the peripheral edge 26&#39; as shown in FIG. 7 and the confronting surface as at 59 will confront the corresponding surface of the glass pane 26. Similarly, the facing portion 52 is identical in appearance, dimension, configuration, etc. to the facing 48 of the attachment bar 24 thereby forming an identical appearance of the colonial grid on both opposite surfaces of the panes 26. 
     Now that the invention as a structure and process have been described,
