TITLE: WINDOW ASSEMBLIES INCLUDING BRONZE ELEMENTS

This application claims priority to, the benefit of, and incorporates herein by reference US Application Serial No. 13/838,269, filed 3/15/2013; and US Application Serial Number No. 61/647,796, filed 5/16/2012.

BACKGROUND OF INVENTION

[1] The fenestration industry dates from antiquity and mankind has used many methods of securing the openings in buildings that provide light, air and access. After the invention of steel and the methods of readily producing clear glass were developed it became commonplace to enclose openings by means of slender steel framework that held glass panels by means of clips and glazing putty. This allowed for a higher level of shelter to be constructed. Windows made from steel and glass allowed natural light while providing protection from the elements and this paved the way to control indoor temperature. The invention of air conditioning induced a further need to control air infiltration, radiant energy and thermal transfer and consequently steel window production slowly gave way to more energy efficient methods of construction. This transition significantly altered the architectural style that had been established with the low profile steel windows. The applicants present invention allows for the architectural style established with the narrow sight lines of steel windows with a maintenance free window that has the thermal performance required in modern construction.

BRIEF DESCRIPTION OF THE INVENTION

[2] Applicant has created a window typically constructed, in one embodiment, primarily from bronze and brass extrusions with a profile similar to the old fashioned steel windows, that can be dry glazed and with a design that helps reduce thermal transfer through the frame and provides for the use of monolithic or insulated glass. This window system, with the unique single into a building structure, allows for integration into the modern building envelope, providing necessary barrier against moisture, air infiltration and solar energy while maintaining the distinctive architectural style of a bygone era.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[9] Turning to Figure 1 , we see Mulled Window (1) comprised of a Fixed Window (2) and Operating Window (3), joined by common Outside Frame (4). Typically, Fixed Glass (5) is set directly into Frame (4) of Fixed Window (2), although interrupted by Fixed Horizontal Muntin Bar (6) and Vertical Fixed Muntin Bar (7). Active Sash (8) is operably connected to Outside Frame (4) by means of Hinge (12), and supports Horizontal Active Muntin Bar (9) and Vertical Active Muntin Bar (10), which together holds the Sash Glass (11). Of course there are many different configurations that windows can be arranged in, and this drawing is to illustrate the basic parts of one embodiment of the windows in discussion.

[10] In Figures 2a— 2e, we see the Steel Cross Section (20) which is a typical detail of existing art. More specifically we see Steel Cross Section (20) has many of the same components as the Mulled Window (1) of Figure 1, including the Outside Frame (4), Fixed Glass (5), Horizontal Fixed Muntin Bar (6), Active Sash (8), Horizontal Active Muntin Bar (9) and Sash Glass (1 1). Further we see Fixed Glass (5) and Sash Glass (1 1) may be single pane glass and are secured with Glazing Putty (21) which is inserted to seal the edges. Also of note is that the Horizontal Fixed Muntin Bars (6), Outside Frame (4), Horizontal Active Muntin Bar (9) and Active Sash (8) are all constructed of monolithic pieces of metal which readily transmit heat.

[1 1] Figures 3a, 3b and 3c details Bronze Cross Section (30), which is a typical detail of applicant's present invention. In the Bronze Cross Section (30) there are also the components listed in the Mulled Window (1) of Figure 1, including the Outside Frame (4), Fixed Glass (5), Horizontal Fixed Muntin Bar (6), Active Sash (8), Horizontal Active Muntin Bar (9) and Sash Glass (1 1). A distinguishing feature of the applicant's present invention is the double Muntin Snap Joints (35) and Perimeter Snap Joints (36) which comprise of Snap Attachment Channel (40) and corresponding Attachment Clip Ridge (41) which are formed by contouring the wall of Double Muntin Retainers (31) and double Perimeter Retainers (32) and Muntin Base (33) and Perimeter Base (34) respectively. So as the window is constructed, the Double Muntin Retainers (31) and Double Perimeter Retainers (32) are affixed to the Muntin Base (33) and Perimeter Base (34), respectively, and are fastened together at Muntin Snap Joints (35) and Perimeter Snap Joints (36), forming a Glazing Channel (37) to support the glass. It will be noted that Glazing Channel can optionally provide for Sealant Groove (38) to house Glazing Gasket (39) which eliminates the need for glass to be set in a wet bed of sealant, and replaces the Glazing Putty (21) Figure 2 in the prior art. It is also noted that the Fixed Glass (5) and Sash Glass (11) are double pane, or insulated glass, although it could be constructed with single pane glass in the same manner. The Muntin Base (33) and Perimeter Base (34) are typically constructed of a non- metallic material or different density metal coated so as to reduce thermal conductivity, and consequently significantly increasing the insulating properties of the window. Further it can be seen on Bronze Cross Section (30) that Outside Frame (4) is comprised of Active Sash Perimeter Frame (80) at Operating Window (3) for operable attachment to Active Sash (8). Further, the geometry of Active Sash (8) allows for uniformity between Active Perimeter Retainer (42) and the double Perimeter Retainers (32) when viewed from Exterior Face (82). Support Frame (84) can be seen on Interior Face (86) and provides strength and a place to mount commercially available locking hardware. Outside Edge (87) of Active Sash Perimeter Frame (80) is closely contoured to correspond with Inside Edge (88) of Active Sash Perimeter Frame (80), and Weather Stripping (89) is used to seal between Active Sash (8) and Active Sash Perimeter Frame (80).

[12] Figures 4a and 4b, detail Fixed Plaster Flange (50) a cut-away section of Outside Frame (4) with the unique Plaster Flange (51) attached to outside frame (4) and mounted in Structural Wall (48) that is clad with Sheathing (49) such as OSB board. It is noted that Outward Edge (53) is affixed to the Building Structure (54), which can be a 2x4 or any such structural member, and provides a surface for Waterproofing Membrane (55) which can be Tyvek or any suitable building waterproofing membrane, to seal against. Reinforced Plaster (57) can then wrap around Building Structure (54) as a Plaster Return (52) stopping at Plaster Termination (59) as defined by Plaster Pocket Forming Member (56). This allows Plaster Return (52) sufficient thickness to be structurally sound and Trowel Guide (58) forms a utility point to guide the masons trowel as the plaster is applied. Of course, the plaster is referred to as a means of illustration but any exterior building material such as stone or wood could be used instead of the plaster. Once applied, Reinforced Plaster (57), or any whatever building material used to clad the structure, forms one side of the Caulk Channel (60) where Flexible Caulk (61) is applied to form an additional seal against moisture penetration. Thus applicant has demonstrated how the unique Fixed Plaster Flange (50) allows for windows to be installed inset from the Outside Face (63) of Structural Wall (48), allow for the thickness of Plaster Return (52) by means of Plaster Pocket Forming Member (56) and still maintain a complete seal between Outside Frame (4) and Structural Wall (48).

[13] Figures 5a and 5b, Replacement Frame (70) is a cut-away section of Outside Frame (4) with alternate Remodel Flange (71). In practice, Setting Block (72) is fastened to Existing Wall (73) and Remodel Flange (71) is connected the Setting Block (72) by means of Clip (74). Frame is sealed into Existing Wall (73) by means of Flexible Caulk (76).

[14] Figure 6 is a cut-away section of the Alternate Bronze Frame (90), which is an alternate design detail of applicant's present invention. The Alternate Bronze Frame (90) includes some of the components listed in the Mulled Window (1) of Figure 1, including the Outside Frame (4), Fixed Glass (5). The distinguishing feature of the applicant's alternate configuration is the combination of Alternate Perimeter Base (92) and Inside Perimeter Stop (94) into a one piece Perimeter Retainer Base (95). Perimeter Retainer (96) is then applied to Perimeter Retainer Base (95) to secure the glass. The utility of this can be applied to Active Sash (8) and Muntin Bar (6) on Figure 3.

[15] Although the invention has been described with reference to a specific embodiment, the description is not meant to be construed in a limiting sense. On the contrary, various

modifications of the disclosed embodiments will become apparent to those skilled in the art upon reference to the description of the invention. It is therefore contemplated that the appended claims will cover such modifications, alternatives, and equivalents that fall within the true spirit and scope of the invention.
