FIELD OF THE INVENTION ~ - _ . The present invention relates to fastening methods and apparatus and more particularly, to-a method and apparatus suitable for extending the depth of a frame.
_.
BACKGROUND OF THE INVENTION
A standard depth for window assemblies is approximately three and-one-half inches. This relatively standard depth lends-itself well to installation of. window assemblies in buildings having wall supporting frames built with two by four studs, because any openings for windows axe framed by-studs that are three and one-half inches deep-. On the other hand, this relatively standard depth-does not lend itsel~ particularly well to installation in.buildings having wall supporting frames built with two by six studs, because any openings for windows-ar-e-framed by studs that are five and one-half inches deep.-Nonetheless, economies of scale often discourage the production of five and one-half inch deep window assemblies, perhaps because the bulk. of demand for-windows to- date has been in connection with two by four 25- construction. Thus, a need exists to facilitate installation of three and one-half- inch deep window assemblies into openings framed by five and one-half inch studs or jambs in a manner that is attractive and cost effective. -SBMMARY OF THE INVENTION
The present invention provides--an assembly for extending the effective depth of a frame-to-be secured within an opening-having a-depth greater than that of 35 the frame itself. In this context, "depth" is measured in a direction perpendicular from a-plane defined by the frame or matter.retained within the frame. A-channel is associated with each segment of the frame and opens in the direction in which added frame depth is desired.

BACKGROUND OF THE INVENTION
A standard depth for window assemblies is approximately three and-one-half inches. This relatively standard depth lends-itself well to installation of. window assemblies in buildings having wall supporting frames built with two by four studs, because any openings for windows axe framed by-studs that are three and one-half inches deep-. On the other hand, this relatively standard depth-does not lend itsel~ particularly well to installation in.buildings having wall supporting frames built with two by six studs, because any openings for windows-ar-e-framed by studs that are five and one-half inches deep.-Nonetheless, economies of scale often discourage the production of five and one-half inch deep window assemblies, perhaps because the bulk. of demand for-windows to- date has been in connection with two by four 25- construction. Thus, a need exists to facilitate installation of three and one-half- inch deep window assemblies into openings framed by five and one-half inch studs or jambs in a manner that is attractive and cost effective. -SBMMARY OF THE INVENTION
The present invention provides--an assembly for extending the effective depth of a frame-to-be secured within an opening-having a-depth greater than that of 35 the frame itself. In this context, "depth" is measured in a direction perpendicular from a-plane defined by the frame or matter.retained within the frame. A-channel is associated with each segment of the frame and opens in the direction in which added frame depth is desired.
Each channel has a similar, half-dovetail profile.- A
frame extending member is associated-with each channel.
Each frame extending member has_ a profile that includes a first portion which is rotatable into engagement with a respective channel, and a second portion which extends iri the desired direction when the first portion is retained within the channel.- -As applied to a rectangular-window frame, the=
present invention provides a channel eXtending along substantially the entire length of each of-two vertical frame segments, and a channel extending along each of two horizontal frame segments and between the two--vertical-channels and their associated structure. -The first-and second portions on a pair of vertical -extension members extend substantially the entire length of their corresponding vertical channels. The first portions on a pair of horizontal extensian members extend tha distance between the vertical channels and their associated structure;=and the second portions extend the distance between the vertical extension members.
After the vertical-extension members are manipulated into engagement with their Yespective -channels, the horizontal extension members are then manipulated into engagement with their respective channels. The engaged horizontal extension members extend between the vertical extension members and-thereby prevent the vertical extension members from rotating out of engagement with their respective channels. In one embodiment, the ends of the horizontal members snap into place beyond shoulders formed near the ends of the vertical members to secure the extension members-relative to the frame--and one another. In another embodiment, fasteners extend through the vertical extension-members and into the horizontal extension members to similarly hold thehorizontal-extension members in place=. - In either case, the present invention facilitates construction of a sturdy and attractive frame extending structure in a manner that requires few fasteners and consumes little time.
The channel defining structure may be clipped or integrally joined to the frame members to eliminate the need to drive any fasteners into the frame. The elimination of such fasteners is particularly advantageous in cases where the frame is made of plastic or some other material not necessarily conducive to receiving screws or nails. These advantages and others will become apparent upon a more detailed description of the preferred embodiment.
In one aspect, the invention provides a rectangular window assembly, comprising: a first channel extending along a first horizontal frame member; a second channel extending along a second horizontal frame member; a third channel extending along a first vertical frame member and between distal ends and associated structure of the first channel and the second channel; a fourth channel extending along a second vertical frame member and between opposite distal ends and associated structure of the first channel and the second channel; a first extension member; a second extension member;

A preferred embodiment window and window frame extension constructed according to the principles -of the present-invention are collectively designated as 500 in Figure 1.
Windova Frame The window frame 510-includes four window frame members 501-504 that are secured end to end at right angles relative to one another to form the window frame 510. Each of the four window-frame-members 501-50_4 is an extrusion of a composite material including wood and t polyvinyl chloride, and the cross-sectional profile shown in Figure $. The window frame members 501-504~arew welded to one another by applying heat until a bond forms between some of the polyvinyl chloride-in each of two adjacent members.-WO 96f12861 PCTNS95113253 The specifics of~the window frame members 501-504 are shown and described in greater detail (with reference-_to part number 600) in the more recently filed parent application, U.S. Application Serial No.
5 08/490,400, which is incorporated heroin by reference to same. Generally speaking, the frame members 501-504 are suitable.for receiving a pocket replacement-window and converting same for use in window-in/window out replacement or new construction installation. The-liners of the pocket replacement window simply snap into place-on respective frame members 501-504.
A portibn of the window frame segment.504 is shown in Figure 5 and-is representative-of corresponding portions of the. other-window frame segments 501-503.
The segment 504 includes a main beam 517 which receives and supports a respective liner of a window pocket. One end of the beam 517 terminates in an interior end 510 of the segment 504, which extends generally perpendicular to the beam 517 from a wall engaging foot-511-at one end thereof, to an aesthetically curved surface-'513 at an opposite end. A channel is disposed between the foot -511 and the surface 513 and opens towards the interior of the window assembly 500. The cliannel515 is bounded by a first, angled sidewall 516, a bottom wall 514 which extends at an acute angle.rom the first sidewall 516, and a second-sidewall 512 which extends-approximately perpendicular to the bottom wall 514. -Window Frame Extension The window frame extension 520 includes two vertical members 550a and 550b and two horizontal members-650a and 650b which are connected to the window frame 510, as well as oneanother. - The two vertical members 550a and 550b are mirror images of one another, and the two horizontal members 650a and 650b are.also mirror images of one another. The window frame extension 520 is connected to the window 510 to provide additional depth and effectively span a rough opening of 2X6 construction. -In the preferred embodiment, the members 550a and 550b are wood boards, but those skilled in the art-will recognize-that the present-.invention-may be practiced with members made of various materials.- Each of the vertical members SSOa and S50b is an elongate board having a continuous profile or-uniform cross-section -which-is shown in Figure 3.. The profile may be said to-be generally rectangular with a one-half dovetail-~ 60 at one end thereof.- P. top surface 551 and a bottom surface 552 cooperate to define a-boaYd length therebetween. An outwardly facing-surface 553 and an inwardly facing surface 554 cooperate to define a board thickness therebetween. A distal edge 555 and a parallel edge 564 of the one-half dovetail 560 cooperate-to define a board depth therebetween. The top surface 551 and the bottom surface 552 define obtuse angles relative to the distal edge 555 for reasons discussed-below.
In addition to=the parallel edge 564, the one-half-dovetail 560 includes an offset-edge or surface 561 which extends substantially parallel to the edge 564.
The offset edge 561 extends from a frameward end of the outwardly facing surface 553 and cooperates-therewith to define a generally square, external corner: A nested surface 562 extends from an opposite- end of-the offset.
edge 561 and generally perpendicular thereto. A curved surface-563 extends hetween and interconnects the nested surface 562-and the parallel edge 564. The curved surface 563 extends in generally arcuate fashion through approximately ninety degrees and cooperates with the nested surface 562 and the parallel-edge 564 to provide a-continuous and smooth surface.
A fist-'beveled edge or surface 565 extends from an-opposite end of the-parallel edge 564 at an obtuse angle relative thereto. A second beveled edge or-surface 566 extends from an opposite end of the-first beveled edge WO 96112861 PCTlUS95/13255 565 at an acute angle~relative thereto-. An angled edge 567 extends between and interconnects the second beveled ' edge 566 and the inwardly facing surface 554. The angled -edge 567 extends generally perpendicular to the second beveled edge 566._ _ __ In the preferred-embodiment, the members 650a and 650b are also wood boards, but again, those skilled in the art will recognize that the present invention may be practiced with members made of various materials. Each -of the horizontal members 650a and 650b is an elongate board having a profile or cross-section which is shown in Figure 4. The profile is continuous or-uniform except for--notches formed in each end of each of the .
--- members 650a and 650b.- The overall profile is similar -to that of the vertical members 550a and 550b and thus, may also be said to be generally rectangular with a one-half dovetail 660 at one-end thereof. A top surface 651 and a bottom surface -552--cooperate to -define-a board length therebetween. An outwardly facing surface 653 and-an inwardly facingsurface 654 cooperate to define a board thickness therebetween. -A distal edge 655 and a parallel edge 664 0- the one-half-dovetail 660 cooperate __ to define a=board depth therebetween.
In addition to--the parallel edge 664, the one-half dovetail 660 includes an offset edge or surface 661 -which extends substantially parallel to the edge 664.
The offset edge 661 extends from a-frameward end of the outwardly facing surface-653 and cooperates therewith to define a generally square, external-corner. A nested surface 662 eXtends-from an opposite end of theoffset edge 661 and generally perpendicular thereto. A curved surface 663 extends between and interconnects the nested surface'66'2 and the parallel edge 664.-- The curved -.
surface-663 extends in generally arcuate,_fashion through 35- approximately ninety degrees and cooperates with the nested surface 662 and the parallel edge 664 to provide a continuous and smooth surface.-A first beveled edge ar surface-665 extends from an opposite end of the parallel edge 664 at-an obtuse angle relative thereto. A second beveled edge or surface 666 extends from an opposite end of the first beveled edge 665 at an acute angle relative thereto- An angled edge-667 extends between and interconnects the second beveled edge 666 and the--inwardly facing, surface 654. The-angled edge,667 extends generally perpendicular to the second beveled--edge 666'.
A first notch is formed in each end of each of the members650a and 650b by cutting into the inwardly facing surface 654. The cut defines a first plane or edge 671 (or 6-75)- which generally intersects the '-' juncture between the surfaces 654 and 667 and which 15- extends generally parallel-to a line extending from the juncture or-corner=defined between the surfaces 666 and 667 to the juncture or corner defined between the-surfaces '654 and 655. The cut also defines a second plane or edge-672 (or 676) which extends between the first plane 671 (or 675) and the inwardly facing surface 654 and generally perpendicular to each. Hence, the cut into the inwardly facing surface 654 may be madesimply __ by positioning either of the members 650a or 650b on a table saw with the inwardly facing surface 654 facing toward the table, and adjusting the--height of thesaw blade to coincide with the juncture betweenthe surfaces 654 and 667. The width of the edge 671 (or675),-as measured between the second edge 672 (or 676) and-the end 651- (or 652), is approximately equal to the board thickness of-the vertical member to_be secured adjacent thereto. _.
A second notch is formed-in each end of -each of the members ~Sba and 650b by cutting across the inwardly facing surface 654 and the_one-half dovetail 660.== The 35- gut defines a plane or edge 673 (or67_7) which extends substantially perpendicular relative to the inwardly facing surface 654 and at angles of--approximately one -WO 96!12861 PCT/US95/I3255 hundred and thirty-five degrees relative to each of the surfaces651-(or 652) and 664.--These second notches provide clearance for the vertical members 550a and 550b ~ to be inserted into their respective-game members and , rotated into their intended orientation relative thereto.
Each of the extensian-members 550a-b and 650a-b is connected to its respective Frame member in similar fashion. pn eXplariation of this manner of interconnection is made with reference to Figure-5, which shows extension member 55-Ob-relative to its respective frame member 504. The-extension member 550b is positioned relative to the frame member 504 in such a manner that the angled or: leading edge 5.67 is proximate the channel 515 and generally at a mirrored angle relative to the first sidewall 516 thereof. In other words, in this starting position designated at 550b"~
the angled edge;567 and the first sidewall-516 define approximately equal and opposite angles-relative to a line drawn-across-the mount of the channel 515.
The dovetail segment 560 of the extension member 55Db is then moved into the channel 515 to arrive at an intermediate position, which is designated at 560', wherein the curved or trailing edge 562 approaches the mouth of the channel 515 and the second sidewall 512.
The dovetail segment 560 of the extension member 550b is then further inserted into and rotated within the channel 515 to-arrive at a final position, which is shown in solid lines, wherein the angled edge 567 is parallel to the first sidewall 516,-and the parallel edge 564 is parallel to the bottom sidewall 514, and the nested edge 5-62 is parallel to-the second -sidewall 512.
In-this final position relative to the-frame segment 5D4, the extension member 550b cannot be pulled straight out from the channel 515 (in a direction parallel to the main beam 517 of the frame segment 504.
In the preferredembodiment, the horizontal members 650a-b are first connected to their- respective frame segments 501 and 502.--The vertical members--550a-b are subsequently connected to their respective frame segments 503 and 504. The_resilience of the frame ~
5 segments 501 and 502 allows the horizontal (or top-and bottom) extension members--650a=b to-rotate slightly away a from one another tn.receive the vertical extension members 550a-b therebetween. The notches across the corners of the horizontal members 650a-b provide 10 clearance for-the dovetail-segments 560 of the vertical-extension members 550a-b. As the vertical extension members 550a-b are inserted between-the horizontal members 650a-b and rotated into position relative to their respective frame segments-503-504, the opposite ends 551 and 552 thereof snap into-the. notches in the inwardly facing surfaces 654 and behind the edges 672 and 676, respectively,-of the horizontal members 650a-b.
The resilience of the frame segments 501 and 502 then causes--the horizontal (or top and bottom) extension members 650a-b to rotate back toward nne another- to retain the vertical extension members 55Oa-b therebetween (without the-need for any additional-fasteners). Two of-the-resulting corners are shown in Figures 6-and 7.
An application of the present invention is shown in Figure 8 with reference=to_a top view of a casement window 700_ The casement window 700 includes a pocket portion 720 which has been fitted with frame segments 501-504, which in turn; have been fitted with extension =-members 550a-b and 650a-b. The-framed casement window 700 is secured within a rough opening bordered by 2 x 6 studs (2 of which are designated as.1913 and 1914) with a wall-covered by inner and outer sheets 1915-1918. The extension members 550a-b (and 650a-b) cooperate 4~ith the frame segments 503-504 (and 501-502) to span the depth of the opening. Trim pieces 593 and 594 finish off the interior-of-the installed unit.
WO 96f12861 PCT/US95/13255 Alternative Embodiment An alternative embodiment of the present invention ' is discussed with reference-to-Figures 9-11. In one ' application for this alternative-embodiment, a new construction, double hung window assembly 800-includes y extension jamb clips 841-844 secured about an inwardmost portion of respective frame members (including 201 and 203), as well as outer=frame members-or-moulding (including 881and-883)-secured about anoutwardmost portion of respective.frame members (including 201 and 204), respectively. Extending from the outer frame members 881-884 are nailing flanges (including 891 and 893), which are shown and described in-United States Patent No. 4,958,469 to Plummer. To the-extent that it 15- facilitates understanding of the present invention, this patent application is incorporated herein by reference to same.
When thewindow assembly 800 is placed within the rough opening 802, the frame.-members, extension jamb clips, and outer frame members are adjacent respective jambs (including 811 and 813). The nailing flanges are arranged to extend outward from the outer-frame members and to lie. substantially flush against the first __, exterior sheet 815. Nails or other--fasteners are then used-to secure the nailing flanges to the first exterior -sheet, either before or after a--second exterior sheet 816, such as wood siding, is placed-over-the nailing flanges and the first exterior sheet. The nailing flanges span and thereby seal any gap between the window frame members and the jambs about-the xough opening. A
bead of caulk is then disposed along the juncture 817 between the outer frame members and the second exterior sheet to provide an additional seal. The '.vindoci assembly 800 is also secured within the rough opening by scYews--through the side jamb liners and respective frame members, and into-the side jambs 812 and 814, respectively, and screws 821 through the head jamb liner 370 and the frame member 201, and into the. head jamb 811a. ' -Recognizing that the three and one-half inch deep window assembly 800 does not fully occupy the 2 x-6 ' 5- rough opening, extension jambs 861-864--are provided to span the unoccupied depth of the rough opening. Each of the extension jambs 861-864 is-wood and has the cross-sectional shape or profile of that shown in Figure=10 for thesill extension jamb 861.- The profile includes a relatively long segment 865 and a-relatively short segment-865 that are integrally joined at an obtuse angle relative to one another-to define an elbow-867.
An opposite, distal end 868 of the longer=segment=865 is square relative to the-sides of-the longer-segment 865, as is an opposite, distal end 869 of the shorter-segment 866. The resulting configuration may be said to-provide a half dovetail arrangement having,a leading corner 860 that is chamfered in the manner-shown.
Each of the-extension-jamb clips 841-844 has-the cross-sectional shape or profile of..that shown in Figure 10 for-the clip 841. Theprofile includes a -substantially S-shaped portion extending from an upper distal end 848, laterally across an upper horizontal _ member 847, downward along an upper-vertical member 846, 25V substantially laterally across an intermediate member 845,--downward along a-lower vertical member 853, and laterally across a lower horizontal-member-850, to a lower distal end 858. The-upper horizontal member 847, the upper vertical member 846, and the-intermediate member 845 define a channel or groove 849- therebetween, having a substantially trapezoidal-profile=and opening in a direction opposite the extension jamb 861. The intermediate member 8_45, the lower vertical member 853, and the lower horizontal--member 850-define a channel or groove-859 therebetween,-having a substantially-trapezoidal profile and opening-in-a direction toward the extension jamb 861-. The lower horizontal member 850 WO 96!12861 PCTJUS95113255 and the lower vertical member 853 cooperate ta-define an angle A therebetween. The angle~A is slightly less than-ninety degrees, eight-e-fight degrees to be exact, so as to provide a resilient clamping forceagainst an extension jamb inserted therebetween. -The chamfered ~ corner 860 helps to wedge the end.869 between corner 857 and the end 858-of the wall 850.
The lowerhorizontal member 850 extends from the distal end 858 beyond the-=lower vertical member 853 and integrally joins an additional vertical member 851 that may be said to be barbed. The barbed vertical member 851 cooperateswith the lower vertical member 853 and a portion of the lower horizontal member 850 to define a channel or groove-852, which opens in a direction away from the lower horizontal member 850. A-shoulder 854 projects from the barbed vertical member 851 into the groove 852..,The groove 852 receives the barbed end on the window frame 201 and the respective shoulders on the frame end-and the barbed vertical member 852 interengage to resist withdrawal of the frame end from the groove -852. In this manner, thejamb extension clips 841-844 are secured to the window frame members, respectively, to arrive at the arrangement 840 shown in Figure 23.
The width of each channel 859 is substantially similar to the width of the shorter-segment 866 ozi each of the extension jambs 861-864. Beginning with each of the side jamb extensions 862 and 864, each extension is oriented relative to a respective clip as shown in Figure 10._the angled side or leading-edge 876 is 30- positioned proximate the corner 857, and the shorter segment 866 is i:iiserted into the channel 859 until the leading corner 860 contacts the lower vertical member 853. Each of the_side extension jambs 862 and 864 is -.-- then rotated relative to a respective clip 842 and 844 -.
35- in the manner indicated by the arrow R in Figure 10.
The corner 860_travels into a recessed area formed by the acutely angled corner-856 between-the intermediate member 845-aiid the lower- vertical member 853; the end 869 moves into a substantially flush or aligned orientation relative to the lower vertical member 853;
and a portion of the longer member 865 moves into a ' su-bstantially flush or aligned orientation relative to the lower horizontal member 850. The same procedure is then followed for the head jamb extension 861 and the sill jamb extension 863. - --As shown in Figure 9, the side jawb-clips 842 and 844 and-the side jamb extensions 862 and 864 extend lengthwise substantially the entire length of the window assembly 800: On-the other hand, the head jamb clip 841 and the sill jamb clip 843; and the head jamb extension 861 and the sill jamb extension 853 extend lengthwise less than the entire width of the window assembly SDO, because they are bordered at opposite ends by the side jamb clips 8.42 and 844 and the side jamb extensions 862 and 864, respectively. The shortersegments 866 of the head and sill jamb extensions 861 arid 863 extend lengthwise the same distance-as the-head and sill:-jamb clips 841 and-843, respectively.- The longer segments 865 of- the head and sill jamb extensians 861 and 863 extend lengthwise beyond the shorter segments 866 to span the upper vertical members 846 of the.side jamb clips 842 and 844 and abut the side jamb extensions 862-and 864. Once the head and sill jamb extensions 861 and 863 are inserted into their respective clips 841 and 843 and rotated between the opposing side jamb extensions 862 and 864, the four jamb extensions are secured in place by screws 898, which extend through holes 89.9 in the side jamb extensions and into the head and sill jamb extensions. This half dovetail extension jamb arrangement 840 requires only four screws to assemble and eliminates the need oruse of nails or-other fasteners extending from the extension,jambs into the window frame or associated structure.-Once the extension jambs are secured in place, trim CA 02203111 1997-04-18'-members (including 871 and 873) are_secured between the square ends 868 of-the respective extension jambs (including 861 and 863) and the interior sheet of material 817, either before or after the interior sheet 5 of material 817 is coated with paint or some other finish.
A second application for the alternative embodiment is discussed with reference to Figure 12, wherein removal of an existing window assembly, including the 10 frame and moulding, leaves-a rough opening bounded by structural members, in this case "2x4" boards approximately three and one-half inches-wide and one and one-half inches thick.
A suitably sized replacement window-901 is 15 positioned within the rough opening and secured in place by means of screws 921 driven through the-head liner 370 and upper frame'member-201 and into-the head jamb 911a, and screws driven through,the side jamb liners and side frame members and into the respective side jambs.
Interior trim members ,(including 97_1 and 973) are secured between the interior sheet of material 917 and the. upper vertical members 846 on respective jamb clips (including 841 and 843). Exterior trim members (including 991 and 993) are secured to the exterior sheet of material 916. A bead of--caulk -is disposed along a corner defined between each of the trim members and the exterior sheet of--material 916.' The present invention is described with reference to particular embodiments and applications. However, those skilled in-the art will recognize-additional embodiments and applications of the present invention.
Accordingly, the present invention is to be limited only to- the extent of the following claims:
.. .. , ,: ..". ~,.
A portibn of the window frame segment.504 is shown in Figure 5 and-is representative-of corresponding portions of the. other-window frame segments 501-503.
The segment 504 includes a main beam 517 which receives and supports a respective liner of a window pocket. One end of the beam 517 terminates in an interior end 510 of the segment 504, which extends generally perpendicular to the beam 517 from a wall engaging foot-511-at one end thereof, to an aesthetically curved surface-'513 at an opposite end. A channel is disposed between the foot -511 and the surface 513 and opens towards the interior of the window assembly 500. The cliannel515 is bounded by a first, angled sidewall 516, a bottom wall 514 which extends at an acute angle.rom the first sidewall 516, and a second-sidewall 512 which extends-approximately perpendicular to the bottom wall 514. -Window Frame Extension The window frame extension 520 includes two vertical members 550a and 550b and two horizontal members-650a and 650b which are connected to the window frame 510, as well as oneanother. - The two vertical members 550a and 550b are mirror images of one another, and the two horizontal members 650a and 650b are.also mirror images of one another. The window frame extension 520 is connected to the window 510 to provide additional depth and effectively span a rough opening of 2X6 construction. -In the preferred embodiment, the members 550a and 550b are wood boards, but those skilled in the art-will recognize-that the present-.invention-may be practiced with members made of various materials.- Each of the vertical members SSOa and S50b is an elongate board having a continuous profile or-uniform cross-section -which-is shown in Figure 3.. The profile may be said to-be generally rectangular with a one-half dovetail-~ 60 at one end thereof.- P. top surface 551 and a bottom surface 552 cooperate to define a-boaYd length therebetween. An outwardly facing-surface 553 and an inwardly facing surface 554 cooperate to define a board thickness therebetween. A distal edge 555 and a parallel edge 564 of the one-half dovetail 560 cooperate-to define a board depth therebetween. The top surface 551 and the bottom surface 552 define obtuse angles relative to the distal edge 555 for reasons discussed-below.
In addition to=the parallel edge 564, the one-half-dovetail 560 includes an offset-edge or surface 561 which extends substantially parallel to the edge 564.
The offset edge 561 extends from a frameward end of the outwardly facing surface 553 and cooperates-therewith to define a generally square, external corner: A nested surface 562 extends from an opposite- end of-the offset.
edge 561 and generally perpendicular thereto. A curved surface-563 extends hetween and interconnects the nested surface 562-and the parallel edge 564. The curved surface 563 extends in generally arcuate fashion through approximately ninety degrees and cooperates with the nested surface 562 and the parallel-edge 564 to provide a-continuous and smooth surface.
A fist-'beveled edge or surface 565 extends from an-opposite end of the-parallel edge 564 at an obtuse angle relative thereto. A second beveled edge or-surface 566 extends from an opposite end of the-first beveled edge WO 96112861 PCTlUS95/13255 565 at an acute angle~relative thereto-. An angled edge 567 extends between and interconnects the second beveled ' edge 566 and the inwardly facing surface 554. The angled -edge 567 extends generally perpendicular to the second beveled edge 566._ _ __ In the preferred-embodiment, the members 650a and 650b are also wood boards, but again, those skilled in the art will recognize that the present invention may be practiced with members made of various materials. Each -of the horizontal members 650a and 650b is an elongate board having a profile or cross-section which is shown in Figure 4. The profile is continuous or-uniform except for--notches formed in each end of each of the .
--- members 650a and 650b.- The overall profile is similar -to that of the vertical members 550a and 550b and thus, may also be said to be generally rectangular with a one-half dovetail 660 at one-end thereof. A top surface 651 and a bottom surface -552--cooperate to -define-a board length therebetween. An outwardly facing surface 653 and-an inwardly facingsurface 654 cooperate to define a board thickness therebetween. -A distal edge 655 and a parallel edge 664 0- the one-half-dovetail 660 cooperate __ to define a=board depth therebetween.
In addition to--the parallel edge 664, the one-half dovetail 660 includes an offset edge or surface 661 -which extends substantially parallel to the edge 664.
The offset edge 661 extends from a-frameward end of the outwardly facing surface-653 and cooperates therewith to define a generally square, external-corner. A nested surface 662 eXtends-from an opposite end of theoffset edge 661 and generally perpendicular thereto. A curved surface 663 extends between and interconnects the nested surface'66'2 and the parallel edge 664.-- The curved -.
surface-663 extends in generally arcuate,_fashion through 35- approximately ninety degrees and cooperates with the nested surface 662 and the parallel edge 664 to provide a continuous and smooth surface.-A first beveled edge ar surface-665 extends from an opposite end of the parallel edge 664 at-an obtuse angle relative thereto. A second beveled edge or surface 666 extends from an opposite end of the first beveled edge 665 at an acute angle relative thereto- An angled edge-667 extends between and interconnects the second beveled edge 666 and the--inwardly facing, surface 654. The-angled edge,667 extends generally perpendicular to the second beveled--edge 666'.
A first notch is formed in each end of each of the members650a and 650b by cutting into the inwardly facing surface 654. The cut defines a first plane or edge 671 (or 6-75)- which generally intersects the '-' juncture between the surfaces 654 and 667 and which 15- extends generally parallel-to a line extending from the juncture or-corner=defined between the surfaces 666 and 667 to the juncture or corner defined between the-surfaces '654 and 655. The cut also defines a second plane or edge-672 (or 676) which extends between the first plane 671 (or 675) and the inwardly facing surface 654 and generally perpendicular to each. Hence, the cut into the inwardly facing surface 654 may be madesimply __ by positioning either of the members 650a or 650b on a table saw with the inwardly facing surface 654 facing toward the table, and adjusting the--height of thesaw blade to coincide with the juncture betweenthe surfaces 654 and 667. The width of the edge 671 (or675),-as measured between the second edge 672 (or 676) and-the end 651- (or 652), is approximately equal to the board thickness of-the vertical member to_be secured adjacent thereto. _.
A second notch is formed-in each end of -each of the members ~Sba and 650b by cutting across the inwardly facing surface 654 and the_one-half dovetail 660.== The 35- gut defines a plane or edge 673 (or67_7) which extends substantially perpendicular relative to the inwardly facing surface 654 and at angles of--approximately one -WO 96!12861 PCT/US95/I3255 hundred and thirty-five degrees relative to each of the surfaces651-(or 652) and 664.--These second notches provide clearance for the vertical members 550a and 550b ~ to be inserted into their respective-game members and , rotated into their intended orientation relative thereto.
Each of the extensian-members 550a-b and 650a-b is connected to its respective Frame member in similar fashion. pn eXplariation of this manner of interconnection is made with reference to Figure-5, which shows extension member 55-Ob-relative to its respective frame member 504. The-extension member 550b is positioned relative to the frame member 504 in such a manner that the angled or: leading edge 5.67 is proximate the channel 515 and generally at a mirrored angle relative to the first sidewall 516 thereof. In other words, in this starting position designated at 550b"~
the angled edge;567 and the first sidewall-516 define approximately equal and opposite angles-relative to a line drawn-across-the mount of the channel 515.
The dovetail segment 560 of the extension member 55Db is then moved into the channel 515 to arrive at an intermediate position, which is designated at 560', wherein the curved or trailing edge 562 approaches the mouth of the channel 515 and the second sidewall 512.
The dovetail segment 560 of the extension member 550b is then further inserted into and rotated within the channel 515 to-arrive at a final position, which is shown in solid lines, wherein the angled edge 567 is parallel to the first sidewall 516,-and the parallel edge 564 is parallel to the bottom sidewall 514, and the nested edge 5-62 is parallel to-the second -sidewall 512.
In-this final position relative to the-frame segment 5D4, the extension member 550b cannot be pulled straight out from the channel 515 (in a direction parallel to the main beam 517 of the frame segment 504.
In the preferredembodiment, the horizontal members 650a-b are first connected to their- respective frame segments 501 and 502.--The vertical members--550a-b are subsequently connected to their respective frame segments 503 and 504. The_resilience of the frame ~
5 segments 501 and 502 allows the horizontal (or top-and bottom) extension members--650a=b to-rotate slightly away a from one another tn.receive the vertical extension members 550a-b therebetween. The notches across the corners of the horizontal members 650a-b provide 10 clearance for-the dovetail-segments 560 of the vertical-extension members 550a-b. As the vertical extension members 550a-b are inserted between-the horizontal members 650a-b and rotated into position relative to their respective frame segments-503-504, the opposite ends 551 and 552 thereof snap into-the. notches in the inwardly facing surfaces 654 and behind the edges 672 and 676, respectively,-of the horizontal members 650a-b.
The resilience of the frame segments 501 and 502 then causes--the horizontal (or top and bottom) extension members 650a-b to rotate back toward nne another- to retain the vertical extension members 55Oa-b therebetween (without the-need for any additional-fasteners). Two of-the-resulting corners are shown in Figures 6-and 7.
An application of the present invention is shown in Figure 8 with reference=to_a top view of a casement window 700_ The casement window 700 includes a pocket portion 720 which has been fitted with frame segments 501-504, which in turn; have been fitted with extension =-members 550a-b and 650a-b. The-framed casement window 700 is secured within a rough opening bordered by 2 x 6 studs (2 of which are designated as.1913 and 1914) with a wall-covered by inner and outer sheets 1915-1918. The extension members 550a-b (and 650a-b) cooperate 4~ith the frame segments 503-504 (and 501-502) to span the depth of the opening. Trim pieces 593 and 594 finish off the interior-of-the installed unit.
WO 96f12861 PCT/US95/13255 Alternative Embodiment An alternative embodiment of the present invention ' is discussed with reference-to-Figures 9-11. In one ' application for this alternative-embodiment, a new construction, double hung window assembly 800-includes y extension jamb clips 841-844 secured about an inwardmost portion of respective frame members (including 201 and 203), as well as outer=frame members-or-moulding (including 881and-883)-secured about anoutwardmost portion of respective.frame members (including 201 and 204), respectively. Extending from the outer frame members 881-884 are nailing flanges (including 891 and 893), which are shown and described in-United States Patent No. 4,958,469 to Plummer. To the-extent that it 15- facilitates understanding of the present invention, this patent application is incorporated herein by reference to same.
When thewindow assembly 800 is placed within the rough opening 802, the frame.-members, extension jamb clips, and outer frame members are adjacent respective jambs (including 811 and 813). The nailing flanges are arranged to extend outward from the outer-frame members and to lie. substantially flush against the first __, exterior sheet 815. Nails or other--fasteners are then used-to secure the nailing flanges to the first exterior -sheet, either before or after a--second exterior sheet 816, such as wood siding, is placed-over-the nailing flanges and the first exterior sheet. The nailing flanges span and thereby seal any gap between the window frame members and the jambs about-the xough opening. A
bead of caulk is then disposed along the juncture 817 between the outer frame members and the second exterior sheet to provide an additional seal. The '.vindoci assembly 800 is also secured within the rough opening by scYews--through the side jamb liners and respective frame members, and into-the side jambs 812 and 814, respectively, and screws 821 through the head jamb liner 370 and the frame member 201, and into the. head jamb 811a. ' -Recognizing that the three and one-half inch deep window assembly 800 does not fully occupy the 2 x-6 ' 5- rough opening, extension jambs 861-864--are provided to span the unoccupied depth of the rough opening. Each of the extension jambs 861-864 is-wood and has the cross-sectional shape or profile of that shown in Figure=10 for thesill extension jamb 861.- The profile includes a relatively long segment 865 and a-relatively short segment-865 that are integrally joined at an obtuse angle relative to one another-to define an elbow-867.
An opposite, distal end 868 of the longer=segment=865 is square relative to the-sides of-the longer-segment 865, as is an opposite, distal end 869 of the shorter-segment 866. The resulting configuration may be said to-provide a half dovetail arrangement having,a leading corner 860 that is chamfered in the manner-shown.
Each of the-extension-jamb clips 841-844 has-the cross-sectional shape or profile of..that shown in Figure 10 for-the clip 841. Theprofile includes a -substantially S-shaped portion extending from an upper distal end 848, laterally across an upper horizontal _ member 847, downward along an upper-vertical member 846, 25V substantially laterally across an intermediate member 845,--downward along a-lower vertical member 853, and laterally across a lower horizontal-member-850, to a lower distal end 858. The-upper horizontal member 847, the upper vertical member 846, and the-intermediate member 845 define a channel or groove 849- therebetween, having a substantially trapezoidal-profile=and opening in a direction opposite the extension jamb 861. The intermediate member 8_45, the lower vertical member 853, and the lower horizontal--member 850-define a channel or groove-859 therebetween,-having a substantially-trapezoidal profile and opening-in-a direction toward the extension jamb 861-. The lower horizontal member 850 WO 96!12861 PCTJUS95113255 and the lower vertical member 853 cooperate ta-define an angle A therebetween. The angle~A is slightly less than-ninety degrees, eight-e-fight degrees to be exact, so as to provide a resilient clamping forceagainst an extension jamb inserted therebetween. -The chamfered ~ corner 860 helps to wedge the end.869 between corner 857 and the end 858-of the wall 850.
The lowerhorizontal member 850 extends from the distal end 858 beyond the-=lower vertical member 853 and integrally joins an additional vertical member 851 that may be said to be barbed. The barbed vertical member 851 cooperateswith the lower vertical member 853 and a portion of the lower horizontal member 850 to define a channel or groove-852, which opens in a direction away from the lower horizontal member 850. A-shoulder 854 projects from the barbed vertical member 851 into the groove 852..,The groove 852 receives the barbed end on the window frame 201 and the respective shoulders on the frame end-and the barbed vertical member 852 interengage to resist withdrawal of the frame end from the groove -852. In this manner, thejamb extension clips 841-844 are secured to the window frame members, respectively, to arrive at the arrangement 840 shown in Figure 23.
The width of each channel 859 is substantially similar to the width of the shorter-segment 866 ozi each of the extension jambs 861-864. Beginning with each of the side jamb extensions 862 and 864, each extension is oriented relative to a respective clip as shown in Figure 10._the angled side or leading-edge 876 is 30- positioned proximate the corner 857, and the shorter segment 866 is i:iiserted into the channel 859 until the leading corner 860 contacts the lower vertical member 853. Each of the_side extension jambs 862 and 864 is -.-- then rotated relative to a respective clip 842 and 844 -.
35- in the manner indicated by the arrow R in Figure 10.
The corner 860_travels into a recessed area formed by the acutely angled corner-856 between-the intermediate member 845-aiid the lower- vertical member 853; the end 869 moves into a substantially flush or aligned orientation relative to the lower vertical member 853;
and a portion of the longer member 865 moves into a ' su-bstantially flush or aligned orientation relative to the lower horizontal member 850. The same procedure is then followed for the head jamb extension 861 and the sill jamb extension 863. - --As shown in Figure 9, the side jawb-clips 842 and 844 and-the side jamb extensions 862 and 864 extend lengthwise substantially the entire length of the window assembly 800: On-the other hand, the head jamb clip 841 and the sill jamb clip 843; and the head jamb extension 861 and the sill jamb extension 853 extend lengthwise less than the entire width of the window assembly SDO, because they are bordered at opposite ends by the side jamb clips 8.42 and 844 and the side jamb extensions 862 and 864, respectively. The shortersegments 866 of the head and sill jamb extensions 861 arid 863 extend lengthwise the same distance-as the-head and sill:-jamb clips 841 and-843, respectively.- The longer segments 865 of- the head and sill jamb extensians 861 and 863 extend lengthwise beyond the shorter segments 866 to span the upper vertical members 846 of the.side jamb clips 842 and 844 and abut the side jamb extensions 862-and 864. Once the head and sill jamb extensions 861 and 863 are inserted into their respective clips 841 and 843 and rotated between the opposing side jamb extensions 862 and 864, the four jamb extensions are secured in place by screws 898, which extend through holes 89.9 in the side jamb extensions and into the head and sill jamb extensions. This half dovetail extension jamb arrangement 840 requires only four screws to assemble and eliminates the need oruse of nails or-other fasteners extending from the extension,jambs into the window frame or associated structure.-Once the extension jambs are secured in place, trim CA 02203111 1997-04-18'-members (including 871 and 873) are_secured between the square ends 868 of-the respective extension jambs (including 861 and 863) and the interior sheet of material 817, either before or after the interior sheet 5 of material 817 is coated with paint or some other finish.
A second application for the alternative embodiment is discussed with reference to Figure 12, wherein removal of an existing window assembly, including the 10 frame and moulding, leaves-a rough opening bounded by structural members, in this case "2x4" boards approximately three and one-half inches-wide and one and one-half inches thick.
A suitably sized replacement window-901 is 15 positioned within the rough opening and secured in place by means of screws 921 driven through the-head liner 370 and upper frame'member-201 and into-the head jamb 911a, and screws driven through,the side jamb liners and side frame members and into the respective side jambs.
Interior trim members ,(including 97_1 and 973) are secured between the interior sheet of material 917 and the. upper vertical members 846 on respective jamb clips (including 841 and 843). Exterior trim members (including 991 and 993) are secured to the exterior sheet of material 916. A bead of--caulk -is disposed along a corner defined between each of the trim members and the exterior sheet of--material 916.' The present invention is described with reference to particular embodiments and applications. However, those skilled in-the art will recognize-additional embodiments and applications of the present invention.
Accordingly, the present invention is to be limited only to- the extent of the following claims:
