THIS INVENTION relates to a frame assembly for a window or a door.

The Inventor is aware of aluminium frame assemblys, for © 5 doors and more commonly for windows. While these frame assemblys can be finished to be aesthetically attractive, they are relatively expensive and not very strong. The Inventor wishes to alleviate these problems.

According to one aspect of the invention, there is provided a frame assembly which includes: at least one steel frame defining an aperture to accommodate a pane or panel; a beading arrangement attached or attachable to the frame around a periphery of the aperture, the beading arrangement defining an attachment formation to accommodate a lining; and a lining of a synthetic polymeric material, the lining, in use, being configured to hold the pane captive within the aperture.

The beading arrangement may include a base beading and a glaze beading which are interconnectable with each other, the base beading being attached or attachable to the frame.

The beading arrangement may be selected from one of aluminium and steel.

} | CL wn = . ’ The beading arrangement may be attached or attachable to the frame by means of one of an adhesive, welding and mechanical fasteners.

The frame assembly may include at least one displaceable closure member for closing an access opening. The displaceable closure member may be in the form of a sash, the frame assembly in such case also including a stationary steel frame to which the sash is displaceably mounted. :

The frame assembly may include at least one burglar bar across the access opening.

The steel frame may be fixed and may include at least one 40 mullion member.

The term mullion is understood to denote a member or bar (whether upright or otherwise) dividing a window or other opening. 45 The base beading may be in the form of a flat beading or of a mullion beading.

Outer surface of the frame assembly and/or of the glaze beading may be powder-coated. 50

The invention will now be further described, by way of example, with reference to the accompanying diagrammatic drawings.

In the drawings: 55 Figure 1 shows a three-dimensional view of a frame assembly, in: accordance with the invention;

Figure 3 shows a three-dimensional view of a base beading for use 60 with a mullion of Figure 1;

Figure 4 shows a three-dimensional view of a glaze beading for use with the base beadings of Figures 2 and 3;

Figure 5 shows a cross-sectional view of a beading arrangement comprising the beadings of Figures 2 and 4 interconnected; 65 Figure 6 shows a cross-sectional view of a beading arrangement comprising the beadings of Figures 3 and 4 interconnected; and

Figures 7A and 7B show exploded views of the beading arrangements of Figures 5 and 6 respectively in relation to a frame. 70 Referring to Figure 1, reference numeral 10 generally indicates a frame assembly in accordance with the invention. In this example, the frame assembly 10 is in the form of a window frame, although a door frame could be constructed similarly. 75 The frame assembly 10 includes a steel frame 12. The frame 12 is configured to define two apertures 14.1, 14.2. The first aperture 14.1 is in the form of an access opening which can be closed by a displaceable closure member in the form of a window sash 16. The sash 16, in turn, defines therein an aperture to receive a pane which, in 80 this example, is a glass window pane 18. The sash 16 includes a conventional support arrangement 16.1 (e.g. stainless steel friction stays) to guide the displacement of the sash 16 and support it in its open position. The sash 16 could include a conventional handle or latch (not illustrated). 85

The frame 12 and sash 16 are of A-grade hot rolled steel.

They may be manufactured by cutting the individual steel sections to their exact size and then butt-welding them together. 90 The second aperture 14.2 is defined by a mullion member 15 and three frame members 15.1 and is also for receiving a window pane 18.

The sash 16 includes a beading arrangement 20 attached 95 thereto and extending peripherally around the aperture. Similarly, the mullion member 15 and the frame members 15.1 include beading arrangements 21, 20 respectively attached thereto and extending peripherally around the aperture 14.2. 100 The beading arrangements 20, 21 each comprise a base beading and a glaze beading (refer to Figures 2 to 6). The base beading is attachable to the frame, i.e. the sash 16, the mullion member 15 and the frame members 15.1, while the glaze beading defines therein a groove to receive a lining of a synthetic polymeric material (e.g. rubber). 105

Referring now to Figures 2 to 4, various individual beadings are illustrated. Figure 2 shows a flat base beading 22 for attachment to the periphery of the sash 16 and to the frame members 15.1. The flat : base beading 22 includes a surface 23 for engaging the sash 16 or the 110 frame members 15.1 and a ridge and groove formation 24 for interconnection with the glaze beading. Figure 3 shows another base beading 26, for connection to the mullion member 15. The mullion base beading 26 also includes a surface 23 for engaging the mullion member and a ridge and groove formation 24 for connection to the glaze 115 beading.

Figure 4 shows a glaze beading 27 which includes a ridge and groove formation 28 for interlocking with either of the formations 24 of the base beadings 22, 26. The glaze beading 27 also defines a groove 120 29 for receiving a corresponding formation in the rubber lining.

The beadings 22, 26, 27 may be of aluminium or of steel.

In Figure 5, the beading arrangement 20 is shown in more 125 detail to include the flat base beading 22 interconnected by means of the ridge and groove formation 24 to the glaze beading 27. The rubber lining (also referred to in trade as a butterfly gasket) is attached to the glaze beading 27. The rubber lining 30 holds the window pane 18 captive, in use, such that the sash 16 is generally air- and watertight. 130

Figure 6 shows a similar mullion beading arrangement 21.

The mullion base beading 26 is interconnected by means of the ridge and groove formation 24 to the glaze beading 27 which accommodates the rubber lining 30. 135

Figures 7A and 7B show respective exploded views of the beading arrangements 20, 21 of Figures 5 and 6 in relation to the frame 12. 140 To assemble and install the beading arrangement 20, the surface 23 of the flat base beading 22 is coated with an adhesive and is applied to an inner face of the sash 16 and/or frame members 15.1. It is to be appreciated that with a square or rectangular sash 16 as illustrated, four sections of flat base beading 22 are applied. The sections of fiat 145 base beading 22 may need to be cut to size to match the dimensions of the sash 16 and/or frame members 15.1 and do not necessarily need to

: - 7 = extend along an entire length of a side of the sash 16 and/or frame members 15.1. ®F2008/02 12 5 150 Next, the rubber lining 30 is fed into the groove 29 defined by the glaze beading 27. The glaze beading 27 is then interconnected with the flat base beading 22 via the ridge and groove formation 24. The rubber lining 30 can then receive a window pane 18 and hold it securely captive within the sash 16. 155

The mullion beading arrangement 21 is applied to the mullion member 15 in similar fashion. The mullion base beading 26 is wider than the flat base beading 22 as a groove or recess defined by the mullion member 15 is deeper than that defined by the sash 16. The mullion 160 beading arrangement 21 in the mullion member 15 together with the beading arrangement 20 of the frame members 15.1 accommodate the window pane 18.

The frame 12 is then installed in an opening of a base 165 structure, such as a wall, and secured thereto, for example by securing means (not illustrated). If desired, burglar bars (e.g. 10 mm x 10 mm solid square bar or 20 mm x 5 mm flat bar) can be fitted across the aperture 14.1 to inhibit entry through the aperture 14.1 when the sash 16 is open. 170

A wedge lining or gasket (not illustrated) is then inserted against the pane 18.

The exterior surfaces of the frame 12 including the sash 16 175 and of the glaze beading 27 are powder coated. The sash 16 may further . include a seal (not illustrated) for providing a seal between the sash 16

C:WORD Specs P422412A00 Lenting Frame Assembly Complete Spec JD/cve 3/5/2008 12:41 PM

} og - and the frame 12 when the sash 16 is closed. For example, the seal may be a moderate density cross-linked EVA/polyethylene blended sponge. 180 It is to be understood that the particular configuration of the frame assembly 10 may vary, for example by having more or fewer access openings 14.1 and corresponding sashes 16, and/or by having more or fewer fixed apertures 14.2 and corresponding mullion members and frame members 15.1. 185

The Inventor believes that the invention as exemplified is advantageous as it provides a product which is durable, inexpensive, low maintenance and aesthetically appealing. Further, the product is stronger than similar products of which the Inventor is aware and has the further 190 advantage that it is strong enough securely to accommodate burglar bars.
