The lower horizontal frame member (70) of the upper glazed unit (71) has a downwardly facing recess (75) which is defined by a generally L-shaped profile formed by a generally horizontal base surface (76) and a downwardly projecting flange (77); the upper horizontal frame member (74) of the rectangular frame of the lower glazed unit (73) is received by the downwardly facing recess (75); and the combined frontal appearance of the lower horizontal frame member (70) of the upper glazed unit (71) and the upper horizontal frame member (74) of the lower glazed unit (73) simulates that of a transom of a sliding sash type window assembly. <IMAGE>

Description

WINDOW ASSEMBLY This invention relates to a window assembly, and particularly, though not exclusively, to an open out, top hung window assembly constructed from extruded material sections, for example UPVC or aluminium, and which is capable of simulating the appearance of a double hung sliding sash window assembly.
It is desirable to be able to supply UPVC or replacement windows which have a traditional or distinctive appearance, and which are made traditionally from timber framed assemblies; for example, the customer may wish to have windows installed which confer a particular character or appearance to the property. One example of such windows are the traditional double hung sliding sash type windows.
Replacement UPVC windows of the sliding sash type are currently available, but these units tend to be quite expensive, whereas the types of UPVC replacement window assemblies which can be manufactured more economically, namely rectangular framed window assemblies having a fixed transom to separate a top open-out hinged unit and a bottom fixed window unit, cannot provide any effective simulation of traditional sliding sash window designs in the current state of the art.
The invention has been developed primarily, though not exclusively, with a view to address these problems by providing a conversion or modification of existing styles of manufacture of windows of the top hung open out type to a window having the appearance of the traditional style double hung sliding sash window.
The invention therefore provides for a simulation of a sliding sash type window assembly, such as a traditional design of timber framed sash window, while using modern materials which require virtually no maintenance.
Thus, a supplier of e.g. UPVC windows may manufacture window assemblies with the traditional double hung sliding sash appearance, but using existing designs of frames and window units in the factory without incurring unacceptable or high setting up and tooling costs. Therefore, windows of this type can be provided at reasonable and attractive prices to the consumer when compared to existing sliding sash window units constructed from extruded UPVC or aluminium sections.
In the specification of UK patent application no 9302206.9 (Publication No GB2263928A), there is disclosed a window assembly of the type having frames made of extruded material and intended to simulate the appearance of a double hung sliding sash type window, said assembly comprising: an outer frame having a transom which divides the frame into an upper window aperture and a lower window aperture; a first glazed unit hingedly mounted in the upper window aperture for movement between open and closed positions, said first unit having a rectangular frame comprising top and bottom horizonal frame members, and substantially vertically extending side frame members; and a second glazed unit fixedly mounted in the lower window aperture, said second unit having a rectangular frame comprising top and bottom substantially horizontal frame members and substantially vertically extending side frame members, and of which the top horizontal frame member forms at least part of said transom; in which the second glazed unit is inset relative to the first glazed unit by an amount sufficient to make it appear that the units could be slid up and down one in front of the other.
The window assembly construction disclosed in GB 2263928A provides an effective simulation (using extruded frame sections) of a sliding sash type window, and the present invention seeks to further enhance the appearance which can be simulated by a window assembly of the general type referred to above.
Accordingly, in a window assembly of the type referred to above, the present invention is characterised by the following features: (1) the lower horizontal frame member of the rectangular frame of the first hingedly mounted glazed unit has a downwardly facing recess which is defined by a generally L-shaped profile formed by a generally horizontal base surface and a downwardly projecting flange; (2) the upper horizonal frame member of the rectangular frame of the second glazed unit is received by said downwardly facing recess; and (3) the combined frontal appearance of the lower horizontal frame member of the first glazed unit and the upper horizontal frame member of the second glazed unit resembles that of a transom of a sliding sash type window assembly.
Thus, the upper horizontal frame member of the lower glazed unit may be entirely received within the downwardly facing recess, in which case the lower edge of the downwardly projecting flange of the rectangular frame of the upper hingedly mounted glazed unit may define the lower edge of the simulated transom when the upper unit is in the closed position.
Alternatively, the lower edge of the upper horizontal frame member of the lower glazed unit may be substantially flush with the lower edge of the downwardly projecting flange, so that together they define the lower edge of the simulated transom.
Accordingly, in preferred embodiments of the invention as described in more detail herein, there is no unsightly downward projection of the upper horizontal frame member of the lower glazed unit below the edge line of the flange of the lower horizontal frame member of the upper glazed unit, and therefore a neat appearance is provided, which can more effectively simulate a traditional design appearance of the transom of a sliding sash type window assembly.
Preferably, the frame sections making up the rectangular frame of the upper hingedly mounted glazed unit are made of extruded UPVC. The lower horizontal frame member of an extruded UPVC section usually defines a relatively shallow (in a vertical sense) depth, and the invention uniquely provides a design in which the top horizontal frame member of the lower fixedly mounted glazed unit can be entirely received within this shallow recess, or at least has its lower edge at substantially the same level as the lower edge of the downwardly projecting flange of the upper horizontal frame member, and therefore a relatively shallow simulated transom appearance is provided.
In view of the relatively shallow depth of the recess defined in which to receive the upper horizontal frame member of the fixed lower glazed unit, it is preferred that the upper horizontal frame member be made of a metal section, preferably aluminium, to provide sufficient strength of the section in which to hold rigidly and reliably the upper horizontal edge of the fixed glazed unit.
The metal section may have a decorative foil adhesively secured thereto, which will have an appearance to correspond with the appearance of the remaining parts of the extruded sections. Thus, if UPVC is used, a white coated foil may be used. Alternatively, if a simulated hardwood appearance is required, a foil with a simulated hard wood surface may be provided e.g. with a mahogany look.
Preferred embodiments of the present invention will be described in detail, by way of example only, with reference to Figures 5 to 7 of the accompanying drawings. However, to facilitate proper understanding of the preferred embodiments of the invention, description will first be made of the embodiments illustrated in the drawings in publication no GB2263928A. The accompanying drawings which are listed below comprise Figures 1 to 4 which appear in publication no GB2263928A, and in which Figures 5 to 7 illustrate preferred embodiments of the invention, and in which: Figure 1 is an exploded view of a window assembly comprising a top hung open-out window, fixed outer frame and fixed glazed unit prior to assembly; Figure 2 is a front view of the assembled window, having the appearance of a traditional double hung sliding sash type window; Figure 3 is a front view of a modified arrangement of window assembly; Figure 4 is a side view corresponding to Figure 3; Figure 5 is a detailed vertical sectional view of a first embodiment of the present invention; Figure 6 is a view, similar to Figure 5, of a further embodiment of the invention; and Figure 7 is a detailed illustration of a still further embodiment of the invention.
Before describing the preferred embodiments of the invention shown in Figures 5 to 7, description will first be made of the window assembly constructions shown in Figures 1 to 4.
The window assembly shown in Figures 1 and 2 is generally indicated by reference 40 and comprise frame sections made of extruded material, such as UPVC for preference, or aluminium. The assembly 40 comprises a top hung open out window 41 mounted in an upper aperture 51 of a fixed frame assembly, generally indicated by 50, with suitable hinging means. The hinging of the window assembly 41 may be achieved with friction side stays mounted on the sides 52 of the upper aperture 51 of frame 50 and to the side rails 42 of the assembly 41, or with conventional hinges at the top.
The hinged sash window (vent) 41 comprises a glazed unit 43 mounted via beads 43a within a frame with mechanical or welded joints 44 and 45 between the side rails 42 and top and bottom rails 47. Side rails 42 are prepared with extending shaped end portions 46 or "horns". This gives the window the appearance of a traditional sliding sash window assembly.
Fixed outer frame 50 is constructed with normal head 48, sill 49 and sides 52 welded together with a transom 53 welded or mechanically jointed to the outer frame, to divide outer frame 50 into upper aperture 51 for openable window assembly 41, and a lower aperture 54 in which a fixed window unit 55 is mounted via side pieces 56 and transom 53. Make up side extrusions 56 are clipped or fixed by screws or other suitable means to the sides of the lower window aperture 54 and horizontally displace the plane of fixed glazed unit 55 mounted in the lower aperture 54 from that of the openable window assembly 41. Thus, upper glazed unit 41 is displaced from the lower glazed unit 55 to simulate the appearance of two sash-type glazed panels which are normally able to slide past each other, as in traditional sliding sash windows.
Thus, the lower glazed unit is inset relative to the plane of the upper (open-out) glazed unit, and gives the appearance that the two units could be slid up and down, one in front of the other like a traditional sliding sash type window assembly.
Figure 2 shows the fully assembled and converted window having the appearance of a traditional double hung sliding sash window. The complete unit has an outer frame feature 50a fixed to the external face of the head and side rails of the outer frame 50 and projecting from the outer frame to a point level with, or beyond the projection of the top hung sash 41. An optional make up extrusion 57 may be added to the upper surface of the bottom of the outer frame 50 and performs the same function as side extrusion pieces 56. This gives the appearance that both sashes are wholly contained and slidable within the outer frame 50 of the window assembly.
The outer frame is connected to a UPVC sub sill 59 to complete the effect. The preferred shape of the end portions 46 of the top hung sash is shown in both Figures 1 and 2; however, ends formed with alternative or decoratively shaped or patterned end portions would still achieve the same effect.
Referring now to Figures 3 and 4, this shows a modified window assembly designated generally by reference 60, having an aluminium or PVC external frame, in which a top window unit 61 is mounted by fasteners 62 shown in Figure 4, and which is built-up from a welded frame, and which is provided with decorative end pieces or "horns" 63, which may be attached as an integral part of the window unit during assembly, or may be applied subsequently by being attached by any suitable means.
Figure 4 shows aluminium clip assemblies 64 employed in the assembly of the top hung window unit.
Referring now to Figure 5, this shows in vertical section a lower horizontal frame member 70 of extruded material, preferably extruded UPVC, and which forms part of a rectangular frame of a top hingedly mounted open out glazed unit 71 which is mounted in a fixed rectangular window frame, of which one vertical side frame member is shown by reference 72. The top horizontal frame member of a lower fixed glazed unit 73 is designated generally by reference 74, and preferably comprises an extruded metal section, more particularly aluminium.
The horizontal frame section 70 forms a downwardly facing recess 75 which is defined bya a generally L-shaped profile formed by a generally horizontal base 76 and a downwardly projecting front flange 77. Frame section 70 can be of standard profile section currently available, and holds captive the lower horizontal edge of the glazed unit 71 by clip-on bead 78 and inner upstand 79 in known manner. An operating handle 80 operates a locking and/or latch mechanism in known manner, and may comprise means to operate e.g. an espagnolette type locking system.
The recess 75 is relatively shallow in depth, and as it is desirable for the horizontal frame section 74 to be received within it, this imposes some constraints with regard to the design and construction of profile 74 which must be sufficiently strong to hold upper horizontal edge of the lower fixed glazed unit 73. Therefore, it has been found best for the section 74 to be made of metal, and preferably aluminium.
As can be seen from Figure 5, the lowest extremity of section 74, comprising lower horizontal surface 81, is located on generally the same level as the lower horizontal edge 82 of flange 77. Therefore, when the top glazed unit 71 is in the closed position as shown in Figure 5, the combined frontal appearance of lower horizontal section 70 and upper horizontal section 74 resembles that of a transom of a sliding sash type window assembly, and with no downward projection of any part of the section 74 which would destroy the illusion of an effective simulation of a sliding sash type window assembly.
The section 74 is a one piece construction which completely embraces the top horizontal edge of lower glazed unit 73, and has a vertically extending inwardly located flange 83 on which can be slideably mounted a decorative elongate plastics strip 84. If desired, decorative foil shown by dashed outline 85, may be applied to the exposed faces of section 74, and this may be white, to blend with extruded sections of UPVC, or provided with a simulated wood grain finish e.g. mahogany, if required.
An alternative embodiment is shown in Figure 6, and parts corresponding with those already described with reference to Figure 5 are given the same reference numerals, and will not be described in detail again.
In this embodiment, the extruded section 74 has an alternative arrangement at its inner end, and replaces the vertical flange 83 with a profile section 83a, having horizontally extending grooves in which seals 86 and 87 can be received, with seal 86 forming a permanent seal with the upper edge of the fixed glazed unit 73, whereas seal 87 forms a weather proof seal with the hinged upper glazed unit 71 when the latter is moved to the closed position, whereby profile section 83a effectively forms an inner upstand against which the upper hinged window can engage. A decorative trim strip 84a can be slideably mounted on profile section 83a.
Figure 7 shows a generally similar arrangement to that of Figure 6, but with the glazed unit 71 omitted, and Figure 7a shows detail of a central locking arrangement operated by handle 80, and to provide espagnolette locking into the fixed side frames which is necessary for a large top hung window unit.
