Abstract

There is disclosed a window of the kind having at least one light (11) comprised by a non-metallic rectangular frame (12) of wood or wood substitute material wherein said rectangular frame (12) has a rebate (14) around the inner edge (15) of its outer face (16), a first extruded section (17) secured to the walls (18) of the rebate (14) lying in the plane of the frame (12), a second extruded section (25) engaged with said first section (17) so as to be restrained against outward movement, resilient sealing strips (22, 29) on opposite inner edges of said first and second sections (17, 25) and a glazing unit (30) firmly gripped around its perimeter between said sealing strips (22, 29).

SPECIFICATION

Window 1 i I 1 45 This invention concerns a window of the kind (hereinafter termed as the kind referred to) having at least one light comprised by a non metallic rectangular frame of wood or wood substitute material. Generally, though not necessarily, there will be several such lights separated by mullions and transoms of some of which lights may be fixed and other of which may be openable.

Many glazing systems are known for sup 15 porting sealed double-glazed units within an inner frame formed from extruded aluminium or plastics sections which is then usually mounted in a surrounding outer frame of tim ber. Disadvantages of such systems include 20 the untraditional appearance of the two frames from the inside and on the possibility of con densation on the inner surfaces of the inner frame particularly when of metal.

The mounting of single glass sheets or 25 sealed double glazing units directly into a tim- 90 ber frame has necessitated a labour intensive operation involving the use of putty and bead ing both of which can deteriorate and require maintenance or replacement before other parts 30 of the window.

It is an object of the present invention to provide a window which overcomes the disad vantages aforesaid.

According to the present invention there is 35 provided a window of the kind referred to wherein said rectangular frame has a rebate around the inner edge of its outer face, a first extruded section secured to the walls of the rebate lying in the plane of the frame, a sec 40 ond extruded section engaged with said first 105 section so as to be restrained against outward movement, resilient sealing strips on opposite inner edges of said first and second sections and a glazing unit firmly gripped around its perimeter between said sealing strips.

The glazing unit may be a sealed double glazed unit.

The first and second extruded sections may have complementary interengageable hook-like 50 formations.

The second extruded section may have a tongue receivable in a channel formation in the first extruded section.

The first extruded section may be dimen 55 sioned so as not to extend inwardly of the rebated portion of the frame.

The first extruded section may include a portion of 'fir-tree' section adapted to be forced into a groove in a wall of the debate 60 for securement.

The invention will be further apparent from the following description with reference to the several figures of the accompanying drawing, which show, by way of example only, one form of window embodying same.

Of the drawing:- Figure 1 is an interior elevation of the window; Figure 2 is an exterior elevation of the win- 70 dow of Fig. 1; Figure 3 is a cross-section through the window on the line 111-111 of Fig. 2; Figure 4 is a cross-section through a first extruded section used in the construction of 75 the window of Fig. 1; Figure 5 is a cross-section through a second extruded section used in the construction of the window of Fig. 1; and Figure 6 is a cross-section through a modi- 80 fied second extruded section.

Referring now to the drawing it will be seen that the window 10 comprises a single fixed light 11 positioned within a surrounding rectangular wooden frame 12. It will be under- 85 stood that the window might comprise a plurality of lights some of which might be fixed and others might be opening.

As best seen from Fig. 3 the frame 12 has a rebate 14 around the inner edge 15 of its outer face 16.

A first extruded aluminium section 17 (see Fig. 4) is secured to the walls 18 of the rebate 14 lying in the plane of the frame 12. In this example the section 17 is secured by 95 means of an integral portion 19 of 'fir-tree' section which is forced into a groove 20 in the walls 18.

The section 17 is of generally L-shape having a slot 21 at its inner edge which locates a resilient sealing strip 22, and a channel forma- tion 23 and hook formation 24.

A second extruded aluminium section 25 (see Fig. 5) has a tongue 26, a hook forma tion 27 and slot 28 on its inner edge which locates a resilient sealing strip 29, and is en gaged with the first section 17 to firmly grip a sealed double-glazing unit 30 around its peri meter between the oppositely disposed seal ing strips 22 and 29.

Engagement of section 25 with section 17 is through location of tongue 26 in channel formation 23 and coupling of the hook forma tions 24 and 27 to restrain the section 25 from outward movement.

The section 17 is dimensioned so as not to extend inwardly of the rebate 14 so as to be unseen when the interior of the window 10 is seen in elevation (Fig. 1).

Any condensation forming on the sections 17 and 25 is constrained to drain to the out side of the wall in which the window 10 is f itted.

The shape of the second section 25 may be modified as shown in Fig. 6 by adjusting the angle of the web 31 connecting slot 28 with tongue 26 to adapt for a glazing unit 30 of different thickness.

It will be appreciated that it is not intended to limit the invention to the above example only, many variations, such as might readily GB2185057A 2 occur to one skilled in the art, being possible, without departing from the scope thereof as defined by the appended claims.

Thus, for example, the portion 19 of section 17 may be omitted, and the section secured by screws, nails or adhesive.

Claims

1. A window of the kind referred to 10 wherein said rectangular frame has a rebate around the inner edge of its outer face, a first extruded section secured to the walls of the rebate lying in the plane of the frame, a second extruded section engaged with said first 15 section so as to be restrained against outward movement, resilient sealing strips on opposite inner edges of said first and second sections and a glazing unit firmly gripped around its perimeter between said sealing strips.

2. A window according to claim 1 wherein the glazing unit is a sealed double-glazed unit.

3. A window according to either claim 1 or claim 2 wherein the first and second extruded section have complementary interengageable hook-like formations.

4. A window according to any preceding claim wherein the second exi--tuded section has a tongue receivable in a channel formation in the first extruded section.

5. A window according to any preceding claim wherein the first extruded section is dimensioned so as not to extend inwardly of the rebated portion of the frame.

6. A window according to any preceding 35 claim wherein the first extruded section includes a portion of 'fir- tree' section adapted to be forced into a groove in a wall of the rebate for securement.

7. A window substantially as described 40 herein with reference to and as illustrated by the figures of the accompanying drawing.

CLAIMS Amendments to the claims have been filed, 45 and have the following effect:- Claims 1 above have been textually amended.

Textually amended claims have been filed as follows:- 1. A window of the kind referred to wherein said rectangular frame has a rebate around the inner edge of its outer face, a first extruded rigid section secured to the walls of 55 the rebate lying in the plane of the frame, a second extruded rigid section engaged with said first section so as to be restrained against outward movement, resilient sealing strips on opposite inner edges of said first 60 and second sections and a glazing unit firmly gripped around its perimeter between said sealing strips.
