This invention relates in general to clad windows and clad personnel entry doors. This invention relates especially to clad door frames which are used in buildings as avenues for people entering and exiting the building, including door assemblies wherein windows are joined to such door frames either as side lites or as overhead transom windows. This invention also relates to overlying clad transom windows used in clad door assemblies. The invention further relates to joining clad window frames to each other, to joining clad door frames to each other, and to joining clad window frames and clad door frames to each other.
Arcuate windows, overlying e.g. a rectangular window, or overlying a door, have achieved an established position in the market for windows and doors. Arcuate windows can provide a desired aesthetic/artistic characteristic to the overall appearance of a building.
Penetration of water into window frames is known as a significant source of deterioration/damage in window frames which use wood as a structural and/or decorative material.
Advances have been made in the fabrication of the arcuate portions of window framing from wood, and in the fabrication of glazing units from glass or other sheet material, for such windows. The nosing portion of the cladding which attaches to the structural window framing is desirably made of a material which is more weather-resistant than wood in order to avoid frequent maintenance to the outside surface of the window structure and to reduce the amount of water which penetrates the window, thereby reaching the wood substrate and causing deterioration of the wood substrate.
Doors and windows are generally assembled by an assembler. The assembler incorporates the respective door slab in a door frame and the respective window glazing in a window frame. As desired, window clusters may be assembled in a single window frame which extends about the outer perimeter of the cluster, and side light windows may be assembled to a door frame.
A window which is located directly over a door or door/sidelight combination is commonly referred to as a transom window. Transom windows are desirably assembled into a common unit with the respective underlying door frame so that the combined structure can be inserted, as a single unit, into the rough opening in the building.
However, the industry has not to date provided adequate interface structure which facilitates easily joining the transom window frame to an underlying door frame during assembly of the transom window to the underlying door frame.
Ongoing advances in development of window and door frames have moved toward extruded aluminum and extruded plastics as materials of choice to face the ambient environment on the outside surface of the building. Extruded aluminum and extruded plastics require only limited maintenance.
Transom windows, and windows in general, are conventionally fabricated in a wide variety of shapes. In some windows, all of the sides are straight. In other windows, some of the sides are arcuate or otherwise curvilinear as in conventional half-round and eyebrow windows. So, while it would be desirable to provide similarly-configured nosings and drip caps, extruded aluminum and extruded plastics, from which nosings and drip caps are commonly made, are typically fabricated in extended production runs as straight-line extrusions, whereby arcuate extrusions of such structures are not available as mass produced articles of commerce.
In some instances, it is desirable to attach an arcuate drip cap to an arcuate nosing, or to an arcuate portion of a nosing. In response to the desire for arcuate nosing material for arcuate windows, the industry has developed the technical capability to bend conventionally-fabricated straight-line rectangular nosing extrusions, without drip caps.
Thus, the industry offers an aluminum nosing which is extruded as a straight nosing. After being extruded as an elongate straight profile nosing, the aluminum nosing is bent to the desired arcuate configuration. In order to have an arcuate drip cap which can be used with such bent/arcuate nosing, a straight, extruded drip cap is separately bent into the desired arcuate shape. The lower surface of the platform of the so-bent drip cap is then positioned over the outer surface of the outer flange of the so-bent nosing, with the inner end of the drip cap in general alignment with the inner-facing web of the nosing. In conventional assemblies, there is no alignment structure in the drip cap or in the nosing which assists in holding the drip cap in alignment over the nosing, or which assists in mounting the drip cap to the nosing. Rather, the assembler places the drip cap on the nosing, and holds the drip cap in “X” and “Y” alignment with the nosing, while attaching the arcuately-formed drip cap to the arcuately-formed nosing, using screws spaced generally uniformly along the full length of the drip cap.
The first function of the screws is to attach the drip cap to the nosing. The second function of the screws is to maintain the alignment between the drip cap and the nosing. In addition, as the screws are tightened, the tightening of the screws acts to force the arcuate configuration of the drip cap and the arcuate configuration of the nosing to conform to each other whereby any variations in the angle or consistency of the arc radii of the drip cap and the nosing are desirably nullified as the drip cap and the nosing are drawn together by the tightening of the screws. In the event of a substantial misalignment of nosing and drip cap, or substantially different subtended arcs, extra tightening force may be used on the screws, along with corrective lateral alignment forces between the nosing and the drip cap, within the limits allowed by the screw holes, to attempt to conform the drip cap and nosing to each other. If too much force is used tightening a screw, the threads may be stripped, either on the screw or on the drip cap or on the nosing. If a user encounters excessive difficulty in assembling an assembly, including potential damage to the nosing or the drip cap, the drip cap or the nosing may be discarded in favor of a different piece, drip cap or nosing, which will, hopefully, be better suited for the desired assembly configuration, or will not be damaged during the assembly process. Even where the nosing and the drip cap are properly configured in terms of cooperative arcuate radii, and where the assembler does not strip any threads, the assembly of the two elements together, and their alignment, are completely dependent on use of acceptable gripping power, and structural integrity, relative to the assembly screws, which are maintained under constant stress. The stress on the screws in the assembly represents a combination of the tension normally needed to hold assembled parts in surface-to-surface contact with each other where both parts are in fact formed to the same arcuate configuration, as well as the tension needed to bend either the nosing or the drip cap, potentially along the full lengths of those parts, in order to correct inconsistencies in the arcuate configurations of the parts being assembled.
Further, the screws present a less-than-desirable appearance to the window framing. The screws tend to catch dirt; and the screws provide potential avenues for water to leak into the window structure. Further, the screws incur a certain labor cost while assembling the assembly. Overall, the screws are attended by a number of negative factors whereby it is desirable to reduce the number of screws which need to be used at locations where the screws are exposed to casual visual observation or where the screws are exposed to ambient weather.
In addition, the assembly process bears a certain risk of misalignment of the drip cap on the nosing. Namely, the worker who is assembling the drip cap to the nosing must ensure that the drip cap remains aligned with the nosing throughout the assembly process, until all of the screws are in place.
For conventional joining of clad window frames to clad door frames, or clad window frames to clad window frames, or clad door frames to clad door frames, the respective frames are typically aligned with each other with the assistance of a jig or other fixture which is not part of either frame. The frames are then secured to each other using fasteners such as screws or nails. A mullion cap or the like is then driven into the molding/nosing kerf receptacles thereby to cover the joint between the frames. Such mullion cap is employed for aesthetic/appearance purposes, and does not contribute significantly to the function of holding the frames secured together. Rather, the securement function is performed by the e.g. screws or nails or other fasteners external of the nosings.
Thus, it is desirable to provide a nosing assembly which has minimum maintenance requirements and which is less susceptible to penetration by air-borne water from the ambient environment.
It is still further desirable to provide a nosing assembly wherein relatively lower levels of attention can be exerted toward holding the respective elements in the desired alignment during the assembly process.
It is yet further desirable to provide such nosing assembly wherein at least a portion of the nosing assembly has been fabricated into an arcuate configuration.
It is yet further desirable to provide an arcuate nosing assembly wherein the elements being assembled generally fit together in such a way that, in the loose assemblage of the nosing and drip cap to each other, the nosing and the drip cap assist in self-aligning themselves with respect to each other.
It is also desirable to provide a method of fabricating an arcuate nosing assembly wherein the assembly method so re-forms the nosing and the drip cap that the re-formed nosing and drip cap, themselves, provide the primary structures which hold the respective elements in fixed relationship with respect to each other.
It is yet further desirable to provide a method of fabricating an arcuate nosing assembly wherein the assembly method comprises positioning the nosing and the drip cap generally in the desired assembly configuration, and then bending the combination of the nosing and the drip cap, with the drip cap to the outside of the bent configuration, the bending of the drip cap and the nosing operating to bind the nosing and the drip cap to each other.
It is further desirable to provide a combination of first and second nosings wherein the nosings are adapted to being at least temporarily assembled to each other using only elements of the nosings to hold the elements of the nosings in such joinder.
It is yet further desirable to provide a combination of first and second nosings wherein structure on the nosings causes the sliding assembling of the nosings into each other to stop when the assembly process reaches the point where the outer-facing webs on the respective nosings define a generally common surface.
It is also desirable that the insert on each of the first and second nosings be assembled into a receptacle on the corresponding other nosing.
It is further desirable to employ clad door frames using nosings of the invention.
It is yet further desirable to provide clad window frames, or clad door/window combinations, using nosings of the invention.
It is still further desirable to provide clad door frames which employ the invention in combination with clad window frames in a single assembly unit.
It is still further desirable to provide clad door frame combinations which employ the invention.
In some embodiments, the invention relates to clad arcuate windows, especially clad arcuate windows which are used in transom configurations overlying a clad window frame or overlying a clad door frame. The invention relates to improved nosing structure for use about the arcuate portion of a clad arcuate transom window, and to improved nosing structure for joining respective window units to each other, for joining respective door units to each other, and for joining clad window units to clad door units.
The invention relates to the interface between a first clad window frame and a second clad window frame, or to the interface between a clad window frame and a clad door frame, or to the interface between a first clad door frame and a second clad door frame.
In general, a clad window includes a glazing unit, held in a structural clad window frame and a clad door includes a door slab held in a structural clad door frame.
A decorative nosing is commonly included at, or added to, the exterior face of the respective clad door frame or clad window frame, which exterior face will face away from the building, generally to provide both exterior aesthetics and to protect the main body of the frame from direct exposure to the weathering/deterioration affects caused by the ambient environment.
In some embodiments of the invention, a combination of an arcuate nosing, and an arcuate drip cap overlying the nosing, are secured together by collective interaction of elements of the nosing and the drip cap. An elongate hook receptacle extends along the length of the nosing, proximate or at an outer flange. An elongate stud receptacle extends along the length of the nosing, also proximate or at the outer flange. Both an elongate hook and an elongate stud extend downwardly from the overlying elongate drip cap. Securement of the drip cap to the nosing is obtained by inter-engaging the elongate hook in the hook receptacle and aligning the stud with the stud receptacle, in a loose engagement combination of straight extruded-aluminum elongate profiles of the respective precursor nosing and precursor drip cap. While the drip cap and nosing are so engaged with each other, the temporary assemblage of the nosing and the drip cap is bent into the desired arcuate configuration, with the inner flange of the nosing being to the inside of the bend, thereby re-forming the combination of the nosing and the drip cap. In the process of bending, reforming the nosing/drip cap combination, to create the desired arcuate nosing assembly configuration, the inter-engaged hook and hook receptacle are re-formed, optionally referred to as “cold-forming”, creating a tightened locking-type engagement between the hook and the hook receptacle. The result is that the nosing and the drip cap are substantially permanently locked to each other as a consequence of the process of bending the assembled nosing/drip cap combination.
In other embodiments of the invention, a nosing, and a drip cap overlying the nosing, are positioned relative to each other by collective interaction of elements of the nosing and the drip cap. An elongate stud receptacle extends along the length of the nosing, proximate or in an outer flange. An elongate stud extends downwardly from the overlying elongate drip cap. Positioning of the drip cap relative to the nosing is obtained by aligning the stud with the stud receptacle, in a loose engagement combination of straight extruded-aluminum elongate profiles of the respective precursor nosing and precursor drip cap. While the drip cap and nosing are so engaged with each other, screw holes are fabricated through the drip cap, and through an outer panel of the nosing. The drip cap is then secured to the nosing using screws extending through the respective holes. The result is that the nosing and the drip cap are substantially permanently secured to each other by the so-employed screws, where the nosing and drip cap are oriented in a straight-line configuration.

An elongate outer-facing web 40 connects to the inner and outer flanges at outer ends 30 and 34. Elongate inner-facing web 42 connects to the inner and outer flanges at inner ends 32 and 36. Elongate intermediate web 44 connects to intermediate portions of the inner and outer flanges.
An elongate stud-receiving receptacle 46, adjacent inner-facing web 42, has an opening 47 extending downwardly and toward the inner flange, from outer surface 38 of outer flange 26. An elongate hook-receiving receptacle 48 has an opening 49 adjacent outer end 34 of outer flange 28. The hook-receiving receptacle extends from the opening 49 toward inner-facing web 42. The hook-receiving receptacle includes a remote upper wall 50 defined between the main body of the receptacle and the upper surface 38 of outer flange 28. Remote upper wall 50 of the hook-receiving receptacle is generally spaced from the remaining portions of nosing 22.
Elongate front facia flange 52 extends downwardly from the inner flange 26, generally as an extended element of inner-facing web 42. In the illustrated embodiment, the front facia flange has a substantially thicker cross-section than either the adjacent inner flange 26 or the adjacent inner-facing web 42.
A first elongate mounting finger 54A extends generally as an extension of the inner flange from the joinder of the inner flange and the inner-facing web. A second elongate mounting finger 54B is spaced from the first mounting finger, generally parallel to the first mounting finger, and extends from the inner-facing web away from the outer-facing web.
Returning to the nosing assembly, elongate drip cap 24 has a platform 60 and a drip flashing flange 61. Platform 60 has an inner end 62, an outer end 64, an upper surface 66, and a lower surface 68. An elongate drip flange 70 extends downwardly from outer end 64 of the platform at an angle “α” of about 30 degrees, more or less in the embodiment illustrated. Angle “α” is required to, and the magnitude of angle “α” is selected to, direct water away from the window frame to a drip edge 71. Thus, the magnitude of angle “α” can vary depending on the particular implementation. An elongate hook 72 extends down from a locus on the platform lower surface which locus is generally toward outer end 64; and the hook extends from there toward inner end 62 of the platform.
An elongate stud 74 extends downwardly from the lower surface 68 of the platform, adjacent inner end 62 of the platform.
The nosing assembly illustrated in
The straight drip cap and the straight nosing can be initially joined together by longitudinally sliding the drip cap and nosing with respect to each other, with the hook engaged in the hook receptacle. With the hook so engaged, the stud is automatically aligned over the stud receptacle and is readily engaged in the stud receptacle.
As a second method of joining the nosing and the drip cap, the nosing and drip cap can be brought together with the lower surface of the drip cap overlying the upper surface of the outer flange, and with the leading edge of the hook at opening 49 of the hook receptacle. With the hook so positioned, the stud is proximate, but displaced from, stud receptacle 46. The drip cap is then slid toward fourth inner end 36 of outer flange 28, to a stop location where the structure of the platform or nosing stops the engaging of the hook into the hook receptacle and the stud is in alignment over the stud receptacle. With the hook so-engaged and fully seated in the hook receptacle, the stud is readily seated in the stud receptacle. Full engagement of the hook and the stud, thus brings the drip cap and the nosing into registered alignment with respect to each other relative to the inner and outer webs, e.g. such that the inner end of the drip cap platform is aligned with the inner end of the outer flange of the nosing.
The nosing and drip cap are easily disassembled from each other at this stage by simply raising the inner end of the drip cap, thus disengaging the stud from the stud receptacle and then sliding the drip cap relatively toward the outer-facing web. As a second disassembly technique, the drip cap can simply be slid longitudinally with respect to the nosing.
With the drip cap so-joined to the nosing, as a temporary assembly that can be readily separated, the temporary assembly can be converted to a permanently-mounted assembly having an arcuate shape. To make such conversion, the temporary assembly is mounted in a bending jig or other suitable machine. The nosing/drip cap assembly combination is then bent into a desired arcuate configuration, typically in a cold-forming process, bending both the drip cap and the nosing together as a single unit. In the illustrated embodiments, the assembly is bent with the inner flange of the nosing disposed toward the interior of the bend and the drip cap platform disposed toward the outside of the bend.
As the bending force is applied collectively to both nosing 22 and drip cap 24, both the nosing and the drip cap, bending together, take on bent configurations generally similar to each other. As the bending force is released, and the normal limited rebound of the cold-formed elements occurs, the now-arcuate upper surface 76 of hook 72 is left in a forceful abutting-type surface-to-surface engagement with the arcuate lower surface 77 of upper wall 50, as illustrated in
In addition to the locking of the nosing and the drip cap to each other, the resulting abutting engagement between the hook and the hook receptacle, and the convoluted path around hook 72, around wall 50, and along the interface between outer flange 28 and platform 60, to inner end 62, serves as a barrier to air-borne water penetrating to inner end 62 of the nosing assembly where such water can potentially reach water-susceptible wood frame 14. Applicant contemplates that such barrier is effective to prevent weather-generated water penetration except, perhaps, in dangerously-violent weather conditions.
In the arcuate embodiments built to date, of which
And, in order to better insure that the two screws which are used are not entry points for water getting into the window frame, once the screw holes are drilled after the drip cap and nosing are bent, caulk or other flexible sealing compound is forced/injected between the drip cap and the nosing, from the ends of the drip cap and nosing, to and past the screw holes. When a screw is installed, and the drip cap and nosing are drawn together, the space between the drip cap and the nosing, at the ends of the nosing and drip cap, is closed. As the distance between the nosing and drip cap is closed, the caulk is forced to spread in the narrowing space, filling voids between the screw and the side walls of the holes, and occupying the space between the nosing and the drip cap. This application of caulk, including the method of spreading the caulk about the holes which present potential water entry points, essentially eliminates risk of water entering the window frame through the screw holes.
The observed abutting surface-to-surface locking-type engagement of the hook and the upper wall of the hook receptacle, with each other, may be at least in part caused by re-forming of the configuration of the hook 72 relative to the hook receptacle 48 as the nosing and the drip cap take on the arcuate configuration, as well as by the collective rebound from the forming/bending operation. Whatever the mechanism, the bending of the nosing and the drip cap, collectively as the nosing assembly, brings the nosing and the drip cap into an essentially inseparable locked engagement at hook 72 and upper wall 50 as illustrated in
Both hook receptacle 48 and stud receptacle 46 extend to depths substantially greater than the depths reached by the hook or the stud. The space between the end of the stud and the end of the stud receptacle is greater than the space occupied by the stud in the receptacle. Similarly, the space between the end of the hook and the end of the hook receptacle is greater than the space occupied by the hook in the hook receptacle. Such greater depths allow for flow of material during the bending of the initially-joined nosing/drip cap assembly.
While hook receiving opening 48 is illustrated on the outer flange, opening 48 can as well be located on the outer-facing web or the inner-facing web. And while the hook receptacle is shown extending toward the inner-facing web, it could as well extend toward the outer-facing web.
What is important for the hook receptacle is that the receptacle extend in such direction that an upper wall of the receptacle, or other structure which is capable of cooperating with a hook to re-form and/or engage the combination, is defined as part of the hook receptacle. In the illustrated embodiment, the combination is re-formed such that the hook and the upper wall of the receptacle are brought into the firm abutting-type locking engagement whereby the drip cap and the nosing are securely bound to each other.
The opening for the hook receptacle can be located on the outer flange as shown, or on the inner-facing web, or on the outer-facing web. For example, opening 49 can be located anywhere along the height of the outer-facing web, e.g. between inner and outer flanges 26 and 28, whereby hook 72 extends down the face of the outer-facing web 40 to the opening. A similar arrangement can, in the alternative, be defined for the inner-facing web 42. When the assembly is bent and released, both the hook, as part of the drip cap, and the receptacle as part of the nosing, are re-formed, and the resulting abutting-type locking engagement is created.
The hook receptacle is illustrated remote from drip flashing flange 61 and the stud receptacle is illustrated proximate the drip flashing flange. The hook receptacle and the stud receptacle can be relocated to generally reversed relative positions, and are typically spaced from each other. The hook and stud are correspondingly relocated also.
In the illustrated embodiments, the nosing and drip cap are elongate aluminum extrusion profiles. As such, each element defined in such profiles typically extends, as extruded, for the full length of the respective profile. Thus, the extrusions generally function as cladding, covering/cladding surfaces of the wood substrate elements which generally provide the structural substance of the window frame and which surfaces would otherwise be exposed to the ambient environment.
While the description herein addresses primarily wood substrates for window and door frames, the substrates can be any desired material including, without limitation, solid plastic substrates, extruded profile plastic substrates, extruded aluminum profiles, pultruded fiberglass-reinforced profiles, or combinations of any of the above, with or without wood elements.
In the illustrated embodiment of

The general size of the nosing profile as seen in
The thus loosely-assembled straight assembly was then placed in a bending jig and bent about an approximately 18-inch radius, measured from the inner flange, into a half-circle, and released from the bending operation. Once released, the assembly retained its general half-circle configuration and the resulting bent assembly exhibited a strong securement of the drip cap and nosing to each other along the bent length, such that the drip cap and the nosing were essentially inseparable from each other along the bent length. A strong abutting-type locking engagement was noted between hook 72 and upper wall 50. Thus, upon completion of the bending process, the drip cap and the nosing were in a locked relationship with each other.
Given the 18-inch radius bend in the subject nosing assembly, the inventor contemplates that even shorter radius bends such as 15 inches radius, or 12 inches radius, or 7.5 inches radius, may be achieved with little if any modification to the disclosed profiles and such shorter-radius profiles are thus considered to be part of the invention. The inventor contemplates that, in light of the disclosure herein, substantially any radius equal to half of the width of conventional commercially-available windows and doors, down to e.g. about 6 inches radius, can be accommodated by making obvious modifications to the nosing and drip cap profiles in order to achieve some of the smaller such radii whereby all such radii are considered to be enabled by the disclosure herein.
The above portion of the detailed description generally refers to the upper arcuate portion of transom window frame 14. Turning now to the interface between transom window 12 and door frame 10, reference is made to

As seen in
An elongate outer-facing web 94 connects to the inner and outer flanges at outer ends 84 and 88. Elongate inner-facing web 96 connects to the outer flange at inner end 90 and extends toward inner end 86.
A first lock 98 on the inner-facing web and a second lock 100 at the inner end 86, of the inner flange define an opening 102 which extends from outside the nosing, between the first and second locks, and into the interior space 104 inside the nosing.
An elongate receptacle 106 has an opening 108 where third outer end 88 of outer flange 82 and the upper end of outer-facing web 94 come together. Thus, opening 108 can be considered either as part of outer flange 82 or as part of web 94. Receptacle 106 extends from opening 108 toward inner-facing web 96. Receptacle 106 includes a remote upper wall 110 defined between the main body of the receptacle and the outer surface 92 of outer flange 82. Remote upper wall 110 is generally spaced from the remaining portions of nosing 76.
Nosing 76 is mounted to jamb cover 112. Jamb cover 112 covers the surfaces of an e.g. wood jamb substrate 114 of the header jamb 79 of the door frame, thus, generally functioning as cladding and thereby covering surfaces of the wood substrate elements which generally provide the structural substance of the door frame and which surfaces are otherwise exposed to ambient environmental conditions. Jamb cover 112 has a main side panel 118 which covers that side of the e.g. wood substrate which faces into the doorway opening. Outer panel 120 of the jamb cover is joined to main side panel 118 at a common corner, and covers the side of the substrate which faces away from the building. Lock structure extends from the outer panel in the physical expression of two lock studs 122A, 122B. Lock studs 122A, 122B interface with first and second locks 98 and 100 on the nosing 76.
Jamb cover 112 can be mounted to the substrate by e.g. screws or other fasteners, not shown, at screw apertures, not shown, between lock studs 122A and 122B, such apertures being spaced along the length of the jamb cover.
Given the relative flexibility in the respective locks on the extruded aluminum nosing 76 and jamb cover 112, nosing 76 can be secured/mounted to the jamb cover, and thus to the illustrated header jamb, by snap-locking the first and second locks 98 and 100 on nosing 76 to studs 122A and 122B on the jamb cover.
Nosing 20 has an inner flange 124, and an outer flange 126 spaced from the inner flange. Inner flange 124 has a fifth outer end 128, a sixth inner end 130, and an inner surface 132. Outer flange 126 has a seventh outer end 134 and an eighth inner end 136.
An elongate outer-facing web 138 connects to the inner and outer flanges at outer ends 128 and 134. Elongate inner-facing web 140 connects to the inner and outer flanges at inner ends 130 and 136. An elongate spacing stud 141 extends down from inner surface 132 of inner flange 124. Spacing stud 141 thus spaces the inner flange of nosing 20 from the outer flange of nosing 76 by a distance which maintains the inner flange of nosing 20 in a generally parallel relationship with the outer flange of nosing 76 for the full depth, between the inner-facing webs and the outer-facing webs, of nosings 76 and 20, whereby outer-facing webs 94 and 138 define a generally common and flat surface.
An elongate receptacle 142 proximate fifth outer end 128 of nosing 20 has an opening 144 spaced, from outer end 128, toward the sixth inner end 130 of inner flange 124. Receptacle 142 extends from opening 144 toward outer-facing web 138. Receptacle 142 includes a remote lower wall 146 defined between the main body of the receptacle and inner surface 132 of inner flange 124. Remote lower wall 146 is generally spaced from the remaining portions of nosing 20.
A first elongate mounting finger 148A extends generally as an extension of outer flange 126 from the joinder of outer flange 126 and inner-facing web 140. A second elongate mounting finger 148B is spaced from the first mounting finger and extends from the inner-facing web away from the outer-facing web, generally parallel to mounting finger 148A.
Elongate front drip flange 150 extends upwardly from the outer flange, generally as an extended element of inner-facing web 140.
In assembling the door frame, left and right side jambs are joined to a header jamb, and optionally to a threshold. In assembling the window frame, the arcuate upper frame section is assembled to the lower straight frame section.
The items illustrated in
The bottom of the window assembly is at the bottom of supports 152. Nosing 20 is mounted to the window frame as illustrated in
The window frame and door frame can be assembled to each other as follows. With the door frame held stationary, the window frame is positioned generally as illustrated in
An e.g. manual pushing force is then engaged at the bottom of the window frame, pushing rearwardly, e.g. on nosing 20, toward fourth inner end 90 of the outer flange of nosing 76. The force required to push the window rearwardly is typically, though not necessarily, within the capability of an average adult. As the window is pushed rearwardly, remote upper wall 110 of nosing 76 becomes at least temporarily engaged in receptacle 142 of nosing 20 and remote lower wall 146 of nosing 20 becomes at least temporarily engaged in receptacle 106 of nosing 76, thus locking nosings 76 and 20 to each other as shown in
In the assembly process, the window frame is moved rearwardly until the outer-facing web 138 on nosing 20 comes into alignment with outer-facing web 94 on nosing 76, such that the two outer-facing webs form a generally common surface as illustrated.
With the nosings so joined, and with the window frame located at its desired final juxtaposition relative to the door frame, the assembly is being held together at the outwardly-facing surface of the assembly, which will face outwardly of a building to which the assembly will be joined, by the interaction of upper wall 110 and lower wall 146 in the respective receptacles. Given the restraints provided by the interactions of the upper and lower walls 110, 146, no mull cap is needed or used to hold the two nosings in the desired nearer/further e.g. vertical relationship with respect to each other. While receptacle slots could be designed into the outer webs of nosings 20 and 76, such that a mull cap could be used, no such receptacles or mull caps are needed, and normally none are employed.
By avoiding the need to use a mull cap, the cost of the mull cap element is avoided, as is the labor cost of installing the mull cap. Also, the dirt and water penetration associated with the two conventional mull cap recesses is avoided. Further, the collective design of walls 110 and 146, along with the respective receptacles, provides ease of assembly, and ease of alignment of the underlying and overlying nosings with respect to each other so as to provide a generally common surface at the front face of the assembly, namely that face which is directed outwardly from the building.
The window is further secured to the door frame header at or adjacent the inwardly-facing surfaces of the assembly. For example, a corrugated sheet fastener 147, illustrated to the right of the header jamb and the supports in
Other methods of securing the window and door to each other are contemplated, such as nails and/or screws toe-nailed through the joint at the inner faces. Or screws or nails can be driven through the wood surface 154 of that portion of the jamb which faces the doorway opening, especially adjacent or under weather seal kerf 156 where such fasteners will be hidden by the weather seal.
The spacings and tolerances of the remote upper and lower walls of the nosings, and the corresponding receptacles are such that the engagements of the upper and lower walls of the respective nosings in the receptacles are substantial frictionally-restrained engagements, such that, even before the frames are further secured to each other at e.g. the inwardly-facing surfaces of the assembly, the nosings tend to remain engaged with each other under modest handling and are not generally released from each other by the action of gravity, even if the temporarily-engaged assembly is re-oriented with limited support for one or more of the door frame and/or the window frame in the assembly.
Within the same context, disengagement of the window frame and the door frame from each other is accomplished by e.g. manually pulling the base of the window frontward toward nosing 76, and tilting the window so spacing stud 141 will clear top surface 92 of nosing 76.
While the process of joining, and disengaging, the nosing and drip cap to the door frame has been described in terms of the window frame being moved relative to the, the joining and disengaging of the nosing and drip cap can as well be accomplished by holding the window frame stationary and moving the door frame, or both the window frame and the door frame can be moved as part of the process of joining and/or disengaging the nosing and the drip cap.
While
Thus, nosing 22 in
Elongate outer-facing web 40 connects to the inner and outer flanges at outer ends 30 and 34. Elongate inner-facing web 42 connects to the inner and outer flanges at inner ends 32 and 36. Elongate intermediate web 44 connects to intermediate portions of the inner and outer flanges.
Elongate stud-receiving receptacle 46, adjacent inner-facing web 42, extends downwardly and toward the inner flange, from outer surface 38 of outer flange 28.
Elongate hook-receiving receptacle 48 has an opening 49 adjacent outer end 34 of outer flange 28. The hook-receiving receptacle extends from the opening 49 toward inner-facing web 42. The hook-receiving receptacle includes a remote upper wall 50 defined between the main body of the receptacle and the upper surface 38 of the outer flange. Remote upper wall 50 of the hook receptacle is generally spaced from the remaining portions of nosing 22.
Elongate front facia flange 52 extends downwardly from inner flange 26, generally as an extended element of inner-facing web 42. In the illustrated embodiment, the front facia flange has a substantially thicker cross-section than either adjacent inner flange 26 or adjacent inner-facing web 42.
First elongate mounting finger 54A extends generally as an extension of inner flange 26 from the joinder of inner flange 26 and inner-facing web 42. Second elongate mounting finger 54B is spaced from the first mounting finger and extends from the inner-facing web away from the outer-facing web, generally parallel to first mounting finger 54A.
Nosing 20 has inner flange 124, and outer flange 126 spaced from the inner flange. Inner flange 124 has fifth outer end 128, sixth inner end 130, and inner surface 132. Outer flange 126 has seventh outer end 134 and eighth inner end 136.
Elongate outer-facing web 138 connects to the inner and outer flanges at outer ends 128 and 134. Elongate inner-facing web 140 connects to the inner and outer flanges at inner ends 130 and 136. Elongate spacing stud 141 extends down from inner surface 132 of inner flange 124 thus to space the inner flange of nosing 20 from the outer flange of nosing 22 by a distance which maintains the inner flange of nosing 20 in a generally parallel relationship with the outer flange of nosing 22 for the full depths of nosings 20 and 22, between the inner-facing webs and the outer-facing webs.
An elongate receptacle 142 proximate fifth outer end 128 of nosing 20 has an opening 144 spaced, from outer end 128, toward the sixth inner end 130 of inner flange 124. Receptacle 142 extends from opening 144 toward outer-facing web 138. Receptacle 142 includes remote lower wall 146 defined between the main body of the receptacle and inner surface 132 of inner flange 124. Remote lower wall 146 is generally spaced from the remaining portions of nosing 20.
A first elongate mounting finger 148A extends generally as an extension of outer flange 126 from the joinder of outer flange 126 and inner-facing web 140. A second elongate mounting finger 148B is spaced from the first mounting finger and extends from the inner-facing web away from the outer-facing web.
Elongate front drip flange 150 extends upwardly from the outer flange, generally as an extended element of inner-facing web 140.
The items illustrated in
The two window frames 14A and 14B, with nosings attached, can be assembled to each other as follows. With the lower window frame 14A held stationary, upper window frame 14B is positioned generally as illustrated in
A pushing force is then engaged at the bottom of upper window frame 14B, such as at nosing 20, pushing rearwardly toward fourth inner end 36 of the outer flange of nosing 22. As the window frame is pushed rearwardly, remote upper wall 50 of nosing 22 becomes engaged in receptacle 142 of nosing 20 and remote lower wall 146 of nosing 20 becomes engaged in receptacle 48 of nosing 22, thus locking nosings 22 and 20 to each other as shown in
In the assembly process, the upper window frame is moved rearwardly until one of the inserts reaches the inner end of the corresponding receptacle, which serves as a stop, terminating the rearward movement of the upper window frame, whereupon the outer-facing web 138 on nosing 20 is in alignment with outer-facing web 40 on nosing 22, such that the two outer-facing webs form a generally common surface as illustrated.
The spacings and tolerances of the remote upper and lower walls and the respective receptacles are such that the engagements of the remote upper and lower walls of the respective nosings in the receptacles are substantial frictional engagements, such that the nosings tend to remain engaged with each other with modest handling and are not generally released from each other by the action of gravity, even if the temporarily-engaged assembly is re-oriented with limited support for one or more of the window frames. Within the same context, disengagement of the window frames from each other is accomplished with substantial e.g. manually-applied force urging the respective frames in a disengaging direction. Restated, while the nosings are not so loosely engaged as to easily disengage with normal handling, neither do the nosings need to be so forcefully held together that disengagement requires more than the force which can be applied manually by an average adult.
With the nosings so joined, and with the upper window frame located at its desired final juxtaposition relative to the lower window frame, the assembly is being held together at the outwardly-facing surface of the assembly, which will face outwardly of a building to which the assembly will be joined. The upper window is further secured to the lower window at or adjacent the inwardly-facing surface of the assembly by e.g. a corrugated sheet fastener 147, or by nails, or screws, all as discussed with respect to
While the process of joining and disengaging the nosings has been described in terms of the upper window frame being moved relative to the lower window frame, the joining and disengaging of the nosings can as well be accomplished by holding the upper window frame stationary and moving the lower window frame, or both members can be moved as part of the joining and/or disengaging of the nosings.
Still referring to
Since the nosing on lower window frame 14A is not bent into an arcuate configuration, the support of intermediate web 44 is not needed, whereby intermediate web 44 becomes optional and can, as desired, be eliminated.
Also because the nosing is not bent into an arcuate configuration in the embodiments illustrated in
Since the nosing on lower window frame 14A is not joined to an arcuate drip flashing flange,
While window frames 14A and 14B have been illustrated as being in overlying, underlying relationship, the same elements and assembly procedures can be used in mounting window frames in a wide variety of collective configurations, thus to mount together multiple window frames/windows in an “X-Y” window matrix having essentially any number of window units in each of the “X” and “Y” directions. Thus, window assemblies can be fabricated in any desired size using a wide variety of assembly configurations, and using a wide variety of window shapes for the designs of the respective windows. Such assemblies can be fabricated in any desired configuration which can subsequently be handled safely for installation.
Any time a straight nosing is being joined to either another straight nosing or a straight drip cap, a flexible sealing compound such as caulk can optionally be spread along the interface before the nosings, or the nosing and the drip cap, are joined to each other. For example and without limitation, in the embodiments of
a)-7(p) illustrate a wide variety of shapes of windows which can be built using the nosings and drip caps, and collective assemblies of such nosings and drip caps.
Any such window having a straight bottom side can be so-mounted to a door header jamb as a transom window. Where the bottom of the window is not straight, the lower edge of the window can be set in an adapter which adapts the lower end of the window to a straight configuration, with the nosing 20 mounted to the lower portion of the adapter.
In the alternative the upper edge of the door frame can be mounted into an adapter which adapts the upper edge of the door frame to the lower edge of the window frame. Either way, the adapter can provide the interface between window and door.
Returning now to the drawings,
A straight drip cap 24 is used with the nosing which extends the top of the window. Drip cap 24 uses e.g. a stud 74 to engage e.g. stud receptacle 46, both of which are illustrated in
Since the hook/hook receptacle combination does not secure the drip cap to the nosing like in the arcuate configuration, the drip cap must be otherwise secured to the nosing. In the illustrated embodiment of e.g.
The above description illustrates that the stud and stud receptacle, in the nosing/drip cap combination, serve a positioning function when the stud is seated in the stud receptacle. Namely, the stud will seat in the stud receptacle only when the drip flashing and the nosing are properly aligned with each other. Thus, the stud/stud receptacle combination always provides certainty that the nosing and drip cap are properly aligned with each other. Thus, even where the nosing and drip cap do not need to be bent, the stud/stud receptacle combination provides a desired benefit of certainty of alignment.
