OUTWARDLY OPENING HINGED WINDOW ASSEMBLY
The present invention relates to casement windows.
More specifically, the present invention provides a window assembly having a novel sash frame made of a combination of metal and plastic.
Casement windows presently available on the market have the sash hinged vertically. The hinge mechanism often allows the open windcw sash to separate completely from the frame and be supported on two bra~kets away from the rame.
This type of hinge mechansim has to have strengthened supports at top and bottom -to carry the full weight of the window and to withstand wind buffeting and other external forces. Casement windows with this type of hinge mechanism are generally opened by means of a lever mechanism with a rotatable handle inside the window frame so that the window can be opened and closed without being touched, thus a fly screen may be placed on the inside of the window without interrupting the opening and closing of the window.
In the past, many windaw sashes were made of wood, however, it is now preferable to make window sashes out of metal, generally steel o~ aluminum. Extrusions of many different cross sections can be easily and cheaply made from aluminum and are light weight and durable. ~lowever, sashes made from metal must have insulation and therefore it is preferable to have outside and inside sash sections made from aluminum extrusions with an insulated central in the form of a portion of vinyl plastic extrusion which has nesting sections and grooves so that the aluminum sections are locked to the vinyl extrugion. The cost of making this type of sash is competitive with a yood quality wood sash because it avoids the necessity of finishing the wood surface, *he extruded sections only have to be cut and assembled. One problem that occurs with sashes made from aluminum and j h~
plastic ex-trusions~ is at the corners. When 45 or mitre corners are used, it is not easy to ensure that adjacent members are aligned correctly. Sometimes a corner is not at exac-tly 90 which requires additional labour t~ correct before a sash can be installed. The present invention provides a window sash made from aluminum extrusions and a plastic insula-ting portion which has a combination mitre joint for thè plastic por-tion and an overlapping lap joint for the aluminum extrusions thus ensuring a good sealO
The present invention overcomes some of the problems herein described and provides a window whose sash has strong corners which are sealed and insulated. In another embodiment the window has a continuous hinge and an arrangement such that when the sash is in the fuIl~ open position, the support for the window sash is provided by the window frame, ;thus avoiding excessive strain on the hinge. There is also provision for easily removing the window sash from the hinge without disassembling the hinge unit.
The present invention provides an outwardly opening hingèd window assembl~ comprisingo an aluminum and vinyl sash assembly and a frame s-tructurè to which one edge of the sash assembl~ is connected b~ means of a continuous hinge.
The sash assembly formed from sections including a central vin~l insulating section with an outside aluminum extrusion section attached to one side and an inside aluminum section attached to the other ~ide of theinsulating section to form a composite sash structure for supporting at least one glass pane, each corner of the sash assembly having a 45 mitre joint for the central insulating section and an overlapping lap joint for the outisde aluminum extrusion section and the inside aluminum extrusion section, each cornar having connection means to hold the outside aluminum extrusion sections the inside-aluminum extrusion sections ~ogether at the overlapping lap In other embodiments the connection means are self ~O 7 ?
~ 3 --tapping screws ex~ending transversely through the overlapping lap joint into one end of the inside aluminum extrusion section and the outside aluminum extrusion section. The continuous hinge may comprise.two gear portions extending for the length of the hinge, one portion a-ttached to the sash assembly and one portion forming part of the frame structure, a clip e~tendi.ng for the length of the hinge holding the two gear portions in gear engaging relationship such that the sash assembly can pivot open and shut, the 10. frame structure having an enyaying member to support the clip when the sash assembly is pivoted open to transfer forces applied to the sash assembly directly to the frame structure.
In yet a further embodiment, a gear portion attached to the sash assembly fits into a groove in the sash assembly extending for the length of the hinge, and including at least one key which slides into at least a portion of the groove and locks the gear portion of the hinge in the groove, removal of the key allows the sash assembly ta be removed from the frame structure leaving the hinge attached to the frame structure.

An outwardly opening hinged window assembly 10 is sh~wn in Figure 1 which has an outsi.de frame structure 11 and two window sash assemblies 1~ which open about a continuous hinge 13 extending for the full height of the sash 12 at both vertical sides of the window frame 11. As can be seen in Figures 2 to 5 which represent sections through the sash ana frame, the top frame as shown in Figure 2, has an outside aluminum extru~ion section 20 which is keyed to a vinyl insulating section 21 which in turn is keyed to an inside aluminum extrusion section 22. The inside aluminum extrusion section 22 has an aperture for an upper spring roller 23 and a ~lap 24 c~vers the roller 23, which has a fly screen 25 wrapped around it. The screen 25, which in some cases may be a blind, extenas through a slot 26 with seals in the ins.ide aluminum e~trusion section 22.
The sash assembly 12 has an outside aluminum extrusion section 30-which keys into an insulating section 31, made of an extruded vin~l section which in turn is keyed to an inside aluminum extruded section 32. A flange 33 on the outside section 30 and a further aluminum extrusion 34 keyed to the inner side of the sash assembly 12 supports twin glass panes 35 which are sealed together and have seals 36 to hold the glazings 35 in place. The sash assembly 12 has seals 37 on the inside section 32 and the outside section 30 where they mate with the frame structure 11 when the sash assembly 12 is closed.
The lower section of the frame assembly 11 like the.
top section incluaes an outside aluminum extrusion section 40 sloped away from the window to permit water to flow away from the building, a central vinyl insulating section 41 and an inside alumin~ extrusion section 42 having an aperture with flap 43 to contain a lower spring roller 44.
The lower roller has a screen or blind wrapped around it which passes through a slot 45 with seals in the inside aluminum extrusion section 42. The lower section of the sash 12 is substantially the same as the upper section.
Triple glass panes 35 are shown rather than the double gla~ings for the top frame. Whether the number of glazings is one, two or three, depends on the requirement for the window assemb].y,. The vertical frame section for the rame structure 11 and sash assémbly 12 is shown in Figure 4 having an outside aluminum e~trusion section 50, a central insulating section 51 made of a vinyl extru~ion and an inside aluminum extrusion section 52. The insulating section 51 represents ' the same section as used in the top frame structure and the lower frame structure. The sash assembly 12 has vertical sections substantially the same as the top and bottom sash sections. The inside sèction 52 of!the frame structure 11 has a groove 53 for a screen a~ blind 25 to fit in. This 2Q groove 53 holds the edge of the blind or screen 25 and acts as a guide when the screen or blind 25 is moved up or down.
The hinge assembly 13 extends for the height of the window sash 12. A first partial geared portion 56 is formed integral with the outside section 50 of the frame structure 25' 11 and mates with a second partial geared portion 57 which is substantially the same as the first geared portion 56. The second geared portion 57, like the first geared portlon 56 is formed of an aluminum extrusian and has one end that fits in a slot 58 of,the outside section'30 of the ~ash assembly 12. ~ ke~ 59'which is preferably formed of vinyl, holds the second geared portion 57 firmly to the outside section 30 of the sash assembly 12. These vinyl keys 59 are fitted at the top and bottom of the sash sections when the keys 59 are removed, then the 'second geared portion 57 moves back in the slot allowing the sash assembly 12 to ~e disc~nnected from the hinge assembly 13. A clip 60 formed of an aluminum extrusion with a U-shaped configuration having rounded inward facing portions at each end, fit into rounded hollow sockets on both geared portions 56 and 57, thus holding the geared portions 56 and 57 in gea~ engaging relationship and allowing one gear portion to rotat~ about the other gear portion. The outside section 50 of the frame structure 11 has a flat surface 61 whi.ch is adapted to be contacted by 10. the back of the clip 60 when the sash 12 is in the open position. This flat surface 61 provides structural relief for the hinge assembly 13 because foxces on the window applied by wind and the like when in the open position are trans-ferred directl~ from the clip ~0 ta the flat surface 61 of the outside section 50 and thus the frame structure 11.
The vertical members of the sash assemblies 12 are illustrated in Figure S showing the sealing arrangement between two sashes when closed. A vertical front strip 70 which has a weather strip seal 37, is joined to th~. vert2cal 20. member of the leftl.hand sash 12. The front strip 70 remains attached to the sash when the window opens thus avoids the necessity of having a fixed cen-tral post in the window openingu Similarily a vertical back plate 71 is joined to the vertical member of the adjacent right hand sash 12 thus ~5 allowing the left hand sash to open first, away from the right hand sash 1.2. The right hand sash 12 may be opened after the left hand sash is in the open position.
A handle 72 is provided on the vertical member of the left hand sash 12 with working mechanisms 73 of a type avai].able on the market today which extended both upwards and downwards from the handle 72 to the top and bottom frame strudture and then extending along on~the top member of the sash in a space 74 provided in the central insulating section 31. The mechanism provides a friction locking such that when the handle 72 is turned, the friction locking mechanism 73 is free and the window can be easily opened.
When the handle is then moved upwards again, the friction locking mechanism 73 in the space 74 in the top member o~
the sash locks the sash 12 in that particular location. A
downward extending probè 75 in a space provided in the central insulating section 31 of -the vertical member of the left hand sash, maves downward to lock into a slot provided in the central section 41 of the lower section of the frame assembly 11. This gives a positive lock when the sash is in the closed position~ Another locking mechanism is provided in the vertical member of thè xight hand sash as shown in Figure 5 wherein a downwardextendingprobe 76 provided in a space in the central ins~lating section 31 of the vertical member of the rlght hand sash, also has a mechanism to move it into another slot provided in the central section 41 of the lower section of the frame assembly 11.
In some emb~diments, handles 72 may be provided on both sashes 12 so that both sashes can be opened independ-ently and locked in any desired position. Because the handles 72 æ e necessary to move the window, ~he screen or blind 25 can be moved up or down as desired so that the handle 72 can be easily reached. If the window is open, the screen 25 can be unrolled to provide a screen right across the window opening. If the windaw is closed, the blind can be unrolled across -the window opening. It is preferred to have the screen and the blind 25 having ends that can join while both the screen 25 and blind are held in the side grooves 53 of the ver-tical section in the frame structure 11. However, thè ends of the screen and blind may be separated so that no screen or blind is provided in the window opening.
The corner arrangement ~or the sash assembly 12 is illustrated in Figures 6 to 9~ As seen in Figure 7, the central insuIating section 31 including the interlocked elements 80 of the inside al~minum extrusion section 32 and t:~'7 .
the outside aluminum extrusion section 30.are all cut at an angle of ~5 D representing the shadea port.ion shown in Figure 7 and the dotted line in ~igure 6 for the vertical member, and the shaded portion shown in Figure 8 and the angle line in Figure 6 for the horizontal member. The outside aluminum extrusion section 30 on the horizontal member has the outside flange 33 cut back to li.ne 78 as shown in outline in Figure 8.
The portion of the outside alwninum extrusion section 3~ and the inside aluminum extrusion section 32 are cut back to line 79 as shown in Figure 6 and in dark line in Figure 8. The cut ends of the vertical member and horizontal ~ember are then joined together and two self tapping screws 81 are inserted through holes drilled in the vertical outside section 30 which extend through as shown in Figures 6 and 7 and fit into sockets 82 provided in the hori~ontal outside section 30. The sockets 82 are integrally formed in the section when it is extruded.
Similarily a self tapping screw 81 is inserted through a hole drilled in the-verticai inside section 32 which extends through and fits into a socket 82 provided in the horizontal inside section 32. Thus a 45 mitre joint i5 provided for the oentral insulating sections 31 which provides an excellent seal, and overlapping lap joints, which are at right angles are pro-vided for the inside sections 30 and the outside sections.
~his configuration of lap joint provides excellent strength, 2S avoids misalignment and positively locks the corners.
Whereas one embodiment of the window assembly has been shown herein, it will be appreciated that var.ious changes may be made to the embodiment shown without departing from the scope of the present invention which is lim:ited only by the followiny claims.
An outwardly opening hinged window assembly 10 is sh~wn in Figure 1 which has an outsi.de frame structure 11 and two window sash assemblies 1~ which open about a continuous hinge 13 extending for the full height of the sash 12 at both vertical sides of the window frame 11. As can be seen in Figures 2 to 5 which represent sections through the sash ana frame, the top frame as shown in Figure 2, has an outside aluminum extru~ion section 20 which is keyed to a vinyl insulating section 21 which in turn is keyed to an inside aluminum extrusion section 22. The inside aluminum extrusion section 22 has an aperture for an upper spring roller 23 and a ~lap 24 c~vers the roller 23, which has a fly screen 25 wrapped around it. The screen 25, which in some cases may be a blind, extenas through a slot 26 with seals in the ins.ide aluminum e~trusion section 22.
The sash assembly 12 has an outside aluminum extrusion section 30-which keys into an insulating section 31, made of an extruded vin~l section which in turn is keyed to an inside aluminum extruded section 32. A flange 33 on the outside section 30 and a further aluminum extrusion 34 keyed to the inner side of the sash assembly 12 supports twin glass panes 35 which are sealed together and have seals 36 to hold the glazings 35 in place. The sash assembly 12 has seals 37 on the inside section 32 and the outside section 30 where they mate with the frame structure 11 when the sash assembly 12 is closed.
The lower section of the frame assembly 11 like the.
top section incluaes an outside aluminum extrusion section 40 sloped away from the window to permit water to flow away from the building, a central vinyl insulating section 41 and an inside alumin~ extrusion section 42 having an aperture with flap 43 to contain a lower spring roller 44.
The lower roller has a screen or blind wrapped around it which passes through a slot 45 with seals in the inside aluminum extrusion section 42. The lower section of the sash 12 is substantially the same as the upper section.
Triple glass panes 35 are shown rather than the double gla~ings for the top frame. Whether the number of glazings is one, two or three, depends on the requirement for the window assemb].y,. The vertical frame section for the rame structure 11 and sash assémbly 12 is shown in Figure 4 having an outside aluminum e~trusion section 50, a central insulating section 51 made of a vinyl extru~ion and an inside aluminum extrusion section 52. The insulating section 51 represents ' the same section as used in the top frame structure and the lower frame structure. The sash assembly 12 has vertical sections substantially the same as the top and bottom sash sections. The inside sèction 52 of!the frame structure 11 has a groove 53 for a screen a~ blind 25 to fit in. This 2Q groove 53 holds the edge of the blind or screen 25 and acts as a guide when the screen or blind 25 is moved up or down.
The hinge assembly 13 extends for the height of the window sash 12. A first partial geared portion 56 is formed integral with the outside section 50 of the frame structure 25' 11 and mates with a second partial geared portion 57 which is substantially the same as the first geared portion 56. The second geared portion 57, like the first geared portlon 56 is formed of an aluminum extrusian and has one end that fits in a slot 58 of,the outside section'30 of the ~ash assembly 12. ~ ke~ 59'which is preferably formed of vinyl, holds the second geared portion 57 firmly to the outside section 30 of the sash assembly 12. These vinyl keys 59 are fitted at the top and bottom of the sash sections when the keys 59 are removed, then the 'second geared portion 57 moves back in the slot allowing the sash assembly 12 to ~e disc~nnected from the hinge assembly 13. A clip 60 formed of an aluminum extrusion with a U-shaped configuration having rounded inward facing portions at each end, fit into rounded hollow sockets on both geared portions 56 and 57, thus holding the geared portions 56 and 57 in gea~ engaging relationship and allowing one gear portion to rotat~ about the other gear portion. The outside section 50 of the frame structure 11 has a flat surface 61 whi.ch is adapted to be contacted by 10. the back of the clip 60 when the sash 12 is in the open position. This flat surface 61 provides structural relief for the hinge assembly 13 because foxces on the window applied by wind and the like when in the open position are trans-ferred directl~ from the clip ~0 ta the flat surface 61 of the outside section 50 and thus the frame structure 11.
The vertical members of the sash assemblies 12 are illustrated in Figure S showing the sealing arrangement between two sashes when closed. A vertical front strip 70 which has a weather strip seal 37, is joined to th~. vert2cal 20. member of the leftl.hand sash 12. The front strip 70 remains attached to the sash when the window opens thus avoids the necessity of having a fixed cen-tral post in the window openingu Similarily a vertical back plate 71 is joined to the vertical member of the adjacent right hand sash 12 thus ~5 allowing the left hand sash to open first, away from the right hand sash 1.2. The right hand sash 12 may be opened after the left hand sash is in the open position.
A handle 72 is provided on the vertical member of the left hand sash 12 with working mechanisms 73 of a type avai].able on the market today which extended both upwards and downwards from the handle 72 to the top and bottom frame strudture and then extending along on~the top member of the sash in a space 74 provided in the central insulating section 31. The mechanism provides a friction locking such that when the handle 72 is turned, the friction locking mechanism 73 is free and the window can be easily opened.
When the handle is then moved upwards again, the friction locking mechanism 73 in the space 74 in the top member o~
the sash locks the sash 12 in that particular location. A
downward extending probè 75 in a space provided in the central insulating section 31 of -the vertical member of the left hand sash, maves downward to lock into a slot provided in the central section 41 of the lower section of the frame assembly 11. This gives a positive lock when the sash is in the closed position~ Another locking mechanism is provided in the vertical member of thè xight hand sash as shown in Figure 5 wherein a downwardextendingprobe 76 provided in a space in the central ins~lating section 31 of the vertical member of the rlght hand sash, also has a mechanism to move it into another slot provided in the central section 41 of the lower section of the frame assembly 11.
In some emb~diments, handles 72 may be provided on both sashes 12 so that both sashes can be opened independ-ently and locked in any desired position. Because the handles 72 æ e necessary to move the window, ~he screen or blind 25 can be moved up or down as desired so that the handle 72 can be easily reached. If the window is open, the screen 25 can be unrolled to provide a screen right across the window opening. If the windaw is closed, the blind can be unrolled across -the window opening. It is preferred to have the screen and the blind 25 having ends that can join while both the screen 25 and blind are held in the side grooves 53 of the ver-tical section in the frame structure 11. However, thè ends of the screen and blind may be separated so that no screen or blind is provided in the window opening.
The corner arrangement ~or the sash assembly 12 is illustrated in Figures 6 to 9~ As seen in Figure 7, the central insuIating section 31 including the interlocked elements 80 of the inside al~minum extrusion section 32 and t:~'7 .
the outside aluminum extrusion section 30.are all cut at an angle of ~5 D representing the shadea port.ion shown in Figure 7 and the dotted line in ~igure 6 for the vertical member, and the shaded portion shown in Figure 8 and the angle line in Figure 6 for the horizontal member. The outside aluminum extrusion section 30 on the horizontal member has the outside flange 33 cut back to li.ne 78 as shown in outline in Figure 8.
The portion of the outside alwninum extrusion section 3~ and the inside aluminum extrusion section 32 are cut back to line 79 as shown in Figure 6 and in dark line in Figure 8. The cut ends of the vertical member and horizontal ~ember are then joined together and two self tapping screws 81 are inserted through holes drilled in the vertical outside section 30 which extend through as shown in Figures 6 and 7 and fit into sockets 82 provided in the hori~ontal outside section 30. The sockets 82 are integrally formed in the section when it is extruded.
Similarily a self tapping screw 81 is inserted through a hole drilled in the-verticai inside section 32 which extends through and fits into a socket 82 provided in the horizontal inside section 32. Thus a 45 mitre joint i5 provided for the oentral insulating sections 31 which provides an excellent seal, and overlapping lap joints, which are at right angles are pro-vided for the inside sections 30 and the outside sections.
~his configuration of lap joint provides excellent strength, 2S avoids misalignment and positively locks the corners.
Whereas one embodiment of the window assembly has been shown herein, it will be appreciated that var.ious changes may be made to the embodiment shown without departing from the scope of the present invention which is lim:ited only by the followiny claims.
