Description
~06026~
This invention relates to an aluminum patio door assembly.
Condensation on the interior metal surfaces of aluminum patio doors is a common complaint in Canadian homes during the winter season. Because aluminum has lower thermal resistance than single glazing, condensation will occur on the frame before the glass. The condensation can cause severe damage to surrounding surfaces. The result may be stained carpet, rotting or lifting of wood floors, peeling paint or similar problems, all of which are unsightly and costly to repair. Another common complaint isairinfiltration, which causes discomfort and heat loss.
To deal with the condensation problem,patio doors assemblies have heen provided in which the fixed lite and the operatIng sash are both provided with hermetically sealed double glazing, sometimes in a thermally broken aluminum frame. This substantially reduces heat conduction between the outside and inside of the assembly and there-fore reduces condensation. However, air infiltration throughthe single sliding door often results in substantial heat loss and discomfort, particularly under windy conditions.
To date the most effective patio door assembly design to reduce condensation and air infiltration has been one which employs two single glazed doors and two fixed lites. In other words, a complete double assembly has been used. However, this arrangement is expensive and also requires a frame of substantial depth, typically eight or nine inches. In house andapartment construction, in which window frames are four inches F less than depth, and in ~ 2 ~ ~
which normal stud or face brick construction is used, the deep frame create.s a major problem. Special concrete curbs must be used, and interior finishes and the size of inside heating con~ector cabinets may be affected.
The present invention solves this difficulty by providing an aluminum patio aoor assembly having a frame which includes a full perimeter central thermal barrier member. Positioned over the thermal barrier member is a fixed lite which is provided with hermetically sealed double glazing. Two sliding sashes are located one on each side of the fixed lite. The operating sashes are at least single glazed. Because of the compact design, employing a single fixed lite and a pair of operating sashes, one on each side of the fixed lite~ the depth of the frame between the indoorand outdoor sides thereof can be made four and one half inches or less. Because of the compact frame depth, the patio door assembly ofthe invention can readily be matched to existing construction.
Further features and advantages of the invention will appear from the following description, taken together with the accompanying drawings, in which:
Fig. 1 is a view looking toward the outdoor side of a typical patio door assembly according to the invention;
Fig. 2 is a section taken along lines 2~2 of Fig. l;
Fig. 3 is a section taken along lines 3-3 of Fig.
l; and Fig. 4 is a view taken along lines 4-4 of Fig. 1.
Reference is now made to the drawings, which show a patio door assembly according to the invention and generally indicated at 10. The patio door assembly 10 includes a 106~Z6~
rectangular exterior frame 12 having a sill 14, a header 16, and a pair of identical jambs 18, 20. Located within the frame 12 is a fixed lite 22 and a pair of identical operating sashes 24, 26, one on each side of the fixed lite 22. A screen door 28 is also shown in all of the drawings except for Fig. 1. The screen door 28 is located on the outdoor side of the assembly.
The construction of the frame 12 of the assembly is as follows. The sill 14 includes(Figs. 3,4)an extruded lQ indoor section 30 having an indoor vertical edge member 32, a top member 34 which slopes downwardly towards the outdoor side of the assembly, a downward step 35, and a half box member 36 having a U~shaped opening 38 which faces toward the outdoor side of the assembly. The sill 30 also includes an extruded outdoor section 40 having a matching half box member 42 with a U~shaped opening which faces toward the indoor side of the assembly. The indoor section 40 also has a downwardly and outwardly sloping top member 46, and a vertical outdoor edge member 48. A s~uare tubular vinyl thermal barrier member 50 having four projecting legs 52 is snapped into the opposed U~shaped openings 38, 44 to join th e indoor and outdoor sections of the sill together. Be-cause the openings 38, 44 diverge inwardly, and the legs 52 diverge towards their tips, a strong mechanical joint is achieved.
An indoor rail 54 projects upwardly from the upper surface of the sill indoor section 30 of the sill and extends along the entire sill. The rail 54 is approximately centred on the upper surface of-the sill indoor section 30. A
3Q si~ilar outdoor rail 56 extends upwardly from the upper , .: .
"` 106026~
surface of the sill outdoor section 40 and is located at the same distance from the thermal barrier member 50 as is the indoor rail 54. The height of the outdoor rail 56 is greater than that ofthe indoox rail 54, so that the upper surfaces of both rails are located in the same horizontal plane.
Projecting upwardly from the sill indoor and outdoor sections 30, 40, between the rails 54, 56, are vertical members 58, 60 which form a raised frame. The members 58, 60 have channels 62, 64 at their tops. The purpose of the members 58, 60 will be explained shortly.
To permit escape of water which has condensed or infiltrated within the assembly, spaced weep holes 66 to 74 inclusive are provided in the rails 54, 56 and in the vertical members 32, 58, 60, 48. The holes provide a path for water drainage.
The header 16 is of similar construction to the sill 14,and primed reference numerals are used to indicate corresponding parts. The difference between the header 16 and the sill 14 is that the lower members 34', 46' of the header are entirely horizontal and are not provided with rails or weep holes. In addition, the indoor section 30' of the header is provided with a deep vertically extending pocket 78, defined by members 32' and 58'. The~header outdoor section 40' is provided with a similar deep vertically extending pocket 80defined by member 60' and by another vertically extending member 82.
The constructionof the jambs 18, 20 (Fig. 2) is the same as that of the header 16, except that the pockets therein are less deep. Double primed reference numerals indicate 1060Z6~
corresponding parts in the jambs.
The frame 12 is secured to the building in which it is located by a set of bolts 86 spaced around the indoor sections of the frame and by another set of bolts 88 spaced around the outdoor sections of the frame. The heads of the bolts are located in pockets in the ~rame so that they will not interfere with operation of the sliding sashes.
The fixed lite 22 includes a hermetically sealed double glass unit 90 tFigs. 2, 3) bordered by a full perimeter flexible vinyl glazing spline 92. The vinyl glazing spline ~2 includes opposed outwardly projecting ribs 94 which are set within the openings of the U-shaped channels 62', 64' in the header 16 and in the openings of channels 62", and 64"
in the jamb 20 against which the fixed lite rests (the fixed lite may rest against either jamb). Thus, no separate frame is needed for the top and one side of the fixed lite.
The bottom of the fixed lite 22 is set into an extension frame 96 (Fig. 3). The extension frame 96 has an indoor section 98 and an outdoor section 100. Each section includes an upper channel 102 having an opening to accommodate a rib 94 of the vinyl glazing spline, and also has a vertical wall 106, and a half box section 108 of the same construction as the box sections 38, 42 of the sill.
A thermal barrier member 110 of the same type as barrier member 50 joins and spaces apart the indoor and outdoor sections of the extension frame. Projecting from the bottom of the extension frame 96 are L-shaped legs 112 which fit into the channels 62, 64 of the sill. The extension frame serves to lift the fixed lite so that the bottom of the glazing thereof will be at the same level as the bottom of the glazing in the sliding sashes.
- , ..
~06026~3 The free vertical edge 117 of the fixed lite 22 is provided ~Fig. 2) with a mullion 116, again consisting of an indoor section 118 and an outdoor section 120 separated by a rigid vin~l thermal barrier member 122. The ribs 94 of the vinyl glazing spline 92 project into opposed U-shaped channels 124 in the mullion 116 and the free open end of the mullion is closed by a snap-in vinyl closure 126.
The operating sashes 24, 26 are identical. Each sash includes single glazing 130 set within a rigid vinyl glazing spline 132. The single glazing 130 and spline 132 are setwithin extruded aluminum frames 134 having opposed full perimeter pockets 136 extending therearound. The pockets 136 contain weather stripping 138 to seal the sashes against air infiltration. The upper and lower parts of the sashframes include upper and lower pockets 140, 142 respectively. The lower pockets 142 are provided with conventional adjustable wheels 144 which ride on the rails 54, 56. An operating handle 146 is provided at one end of the indoor sash 26, to move the sash 26. The mullions 150 of the sashes include inwardly projecting L-shaped legs 152 which penetrate into U~shaped recesses 153 in the mullion 116 of the fixed lite, to limit movement of the sashes in the direction of arrow A. Resilient bumpers 154 are fixed to the jamb 18 to limit movement of the sashes in the direction of arrow B.
The screen door 28 includes an exterior frame 156 having upper and lower adjustable wheels 158, 160 respectively.
The wheels 158, 160 ride on third and fourth rails 162, 162' constituted by the free edges of the vertical edge members 48, 48' of the sill and headersections 40, 40'. Little ~ 7 ~
10602~i8 additional frame depth is required for the sreen door, since more than half of the depth of the screen door projects outside the frame 12.
It will be seen that although the upper surface of sill 14 slopes downwardly, the indoor and outdoor rails S4, 56 have their tops aligned, and therefore identical sashes can be used on each side of the fixed lite 22. In addition~ although only a single fixed lite is provided, it can be caulked and can therefore be sealed effectively against wind and water infiltration. Because of the movable :
:~ nature of the sashes, it is more difficult to seal them against wind and water infiltration, but because two are provided, one on each side of the fixed lite, they are separated by a substantial air space to provide good thermal properties, and yet the double sash construction provides a good barrier against wind and water infiltration.

Further features and advantages of the invention will appear from the following description, taken together with the accompanying drawings, in which:
Fig. 1 is a view looking toward the outdoor side of a typical patio door assembly according to the invention;
Fig. 2 is a section taken along lines 2~2 of Fig. l;
Fig. 3 is a section taken along lines 3-3 of Fig.
l; and Fig. 4 is a view taken along lines 4-4 of Fig. 1.
Reference is now made to the drawings, which show a patio door assembly according to the invention and generally indicated at 10. The patio door assembly 10 includes a 106~Z6~
rectangular exterior frame 12 having a sill 14, a header 16, and a pair of identical jambs 18, 20. Located within the frame 12 is a fixed lite 22 and a pair of identical operating sashes 24, 26, one on each side of the fixed lite 22. A screen door 28 is also shown in all of the drawings except for Fig. 1. The screen door 28 is located on the outdoor side of the assembly.
The construction of the frame 12 of the assembly is as follows. The sill 14 includes(Figs. 3,4)an extruded lQ indoor section 30 having an indoor vertical edge member 32, a top member 34 which slopes downwardly towards the outdoor side of the assembly, a downward step 35, and a half box member 36 having a U~shaped opening 38 which faces toward the outdoor side of the assembly. The sill 30 also includes an extruded outdoor section 40 having a matching half box member 42 with a U~shaped opening which faces toward the indoor side of the assembly. The indoor section 40 also has a downwardly and outwardly sloping top member 46, and a vertical outdoor edge member 48. A s~uare tubular vinyl thermal barrier member 50 having four projecting legs 52 is snapped into the opposed U~shaped openings 38, 44 to join th e indoor and outdoor sections of the sill together. Be-cause the openings 38, 44 diverge inwardly, and the legs 52 diverge towards their tips, a strong mechanical joint is achieved.
An indoor rail 54 projects upwardly from the upper surface of the sill indoor section 30 of the sill and extends along the entire sill. The rail 54 is approximately centred on the upper surface of-the sill indoor section 30. A
3Q si~ilar outdoor rail 56 extends upwardly from the upper , .: .
"` 106026~
surface of the sill outdoor section 40 and is located at the same distance from the thermal barrier member 50 as is the indoor rail 54. The height of the outdoor rail 56 is greater than that ofthe indoox rail 54, so that the upper surfaces of both rails are located in the same horizontal plane.
Projecting upwardly from the sill indoor and outdoor sections 30, 40, between the rails 54, 56, are vertical members 58, 60 which form a raised frame. The members 58, 60 have channels 62, 64 at their tops. The purpose of the members 58, 60 will be explained shortly.
To permit escape of water which has condensed or infiltrated within the assembly, spaced weep holes 66 to 74 inclusive are provided in the rails 54, 56 and in the vertical members 32, 58, 60, 48. The holes provide a path for water drainage.
The header 16 is of similar construction to the sill 14,and primed reference numerals are used to indicate corresponding parts. The difference between the header 16 and the sill 14 is that the lower members 34', 46' of the header are entirely horizontal and are not provided with rails or weep holes. In addition, the indoor section 30' of the header is provided with a deep vertically extending pocket 78, defined by members 32' and 58'. The~header outdoor section 40' is provided with a similar deep vertically extending pocket 80defined by member 60' and by another vertically extending member 82.
The constructionof the jambs 18, 20 (Fig. 2) is the same as that of the header 16, except that the pockets therein are less deep. Double primed reference numerals indicate 1060Z6~
corresponding parts in the jambs.
The frame 12 is secured to the building in which it is located by a set of bolts 86 spaced around the indoor sections of the frame and by another set of bolts 88 spaced around the outdoor sections of the frame. The heads of the bolts are located in pockets in the ~rame so that they will not interfere with operation of the sliding sashes.
The fixed lite 22 includes a hermetically sealed double glass unit 90 tFigs. 2, 3) bordered by a full perimeter flexible vinyl glazing spline 92. The vinyl glazing spline ~2 includes opposed outwardly projecting ribs 94 which are set within the openings of the U-shaped channels 62', 64' in the header 16 and in the openings of channels 62", and 64"
in the jamb 20 against which the fixed lite rests (the fixed lite may rest against either jamb). Thus, no separate frame is needed for the top and one side of the fixed lite.
The bottom of the fixed lite 22 is set into an extension frame 96 (Fig. 3). The extension frame 96 has an indoor section 98 and an outdoor section 100. Each section includes an upper channel 102 having an opening to accommodate a rib 94 of the vinyl glazing spline, and also has a vertical wall 106, and a half box section 108 of the same construction as the box sections 38, 42 of the sill.
A thermal barrier member 110 of the same type as barrier member 50 joins and spaces apart the indoor and outdoor sections of the extension frame. Projecting from the bottom of the extension frame 96 are L-shaped legs 112 which fit into the channels 62, 64 of the sill. The extension frame serves to lift the fixed lite so that the bottom of the glazing thereof will be at the same level as the bottom of the glazing in the sliding sashes.

~06026~3 The free vertical edge 117 of the fixed lite 22 is provided ~Fig. 2) with a mullion 116, again consisting of an indoor section 118 and an outdoor section 120 separated by a rigid vin~l thermal barrier member 122. The ribs 94 of the vinyl glazing spline 92 project into opposed U-shaped channels 124 in the mullion 116 and the free open end of the mullion is closed by a snap-in vinyl closure 126.
The operating sashes 24, 26 are identical. Each sash includes single glazing 130 set within a rigid vinyl glazing spline 132. The single glazing 130 and spline 132 are setwithin extruded aluminum frames 134 having opposed full perimeter pockets 136 extending therearound. The pockets 136 contain weather stripping 138 to seal the sashes against air infiltration. The upper and lower parts of the sashframes include upper and lower pockets 140, 142 respectively. The lower pockets 142 are provided with conventional adjustable wheels 144 which ride on the rails 54, 56. An operating handle 146 is provided at one end of the indoor sash 26, to move the sash 26. The mullions 150 of the sashes include inwardly projecting L-shaped legs 152 which penetrate into U~shaped recesses 153 in the mullion 116 of the fixed lite, to limit movement of the sashes in the direction of arrow A. Resilient bumpers 154 are fixed to the jamb 18 to limit movement of the sashes in the direction of arrow B.
The screen door 28 includes an exterior frame 156 having upper and lower adjustable wheels 158, 160 respectively.
The wheels 158, 160 ride on third and fourth rails 162, 162' constituted by the free edges of the vertical edge members 48, 48' of the sill and headersections 40, 40'. Little ~ 7 ~
10602~i8 additional frame depth is required for the sreen door, since more than half of the depth of the screen door projects outside the frame 12.
It will be seen that although the upper surface of sill 14 slopes downwardly, the indoor and outdoor rails S4, 56 have their tops aligned, and therefore identical sashes can be used on each side of the fixed lite 22. In addition~ although only a single fixed lite is provided, it can be caulked and can therefore be sealed effectively against wind and water infiltration. Because of the movable :
:~ nature of the sashes, it is more difficult to seal them against wind and water infiltration, but because two are provided, one on each side of the fixed lite, they are separated by a substantial air space to provide good thermal properties, and yet the double sash construction provides a good barrier against wind and water infiltration.
