Abstract

A two part window or door frame comprises an inner frame 10 and an outer frame 20 mounted from either side of an opening, for example window aperture A. At least the inner frame 10, has a peripheral flange 12 for seating against the surface of the opening. The inner frame may abut or co-operate with the outer frame, possibly by means of slot and socket (figure 2), which may incorporate serrated surfaces (figure 7). A window, door or glazing may be arranged to be received in, or integrated with, one of the frames.

Description

24 1 0286 The present invention relates to a frame assembly for a window

or doorway.

When fitting replacement window or doors, it is invariably required, and often a problem, to make good damage caused to the window or door aperture when taking out the original window or door.

I have now devised a frame assembly which is of simple construction and straightforward to fit, yet will overcome or greatly alleviate the problem of making good damage caused when taking out an original window or door.

In accordance with the present invention, there is provided a window or door frame assembly, which comprises an outer frame for fitting into a window or door aperture of a wall from the outside and having a peripheral flange for seating against the outer surface of the wall around the aperture, and an inner frame for fitting into said aperture and into said outer frame from the inside and having a peripheral flange for seating against the inner surface of the wall around said aperture.

It will be appreciated that the inner and outer frames co-operate to completely cover the peripheral surfaces or reveals of the window or door aperture: further, the peripheral flanges of the inner and outer frames cover a margin of the inner and outer surfaces of the wall, around the aperture. The inner and outer frames accordingly cover any damage caused to the reveals, or to the wall around the aperture, when removing the original window or door.

Preferably the inner frame fits into the outer frame in interference manner. The outer frame may be provided with a subsidiary frame on its inner faces, a recess or socket being formed between the outer frame and its subsidiary frame, into which the edges of the inner frame fit. The outer frame may be fixed in position using screws passed through its side, top or bottom elements and into the brickwork. The inner frame may be fixed in position using screws passed through its side, top or bottom elements and into the corresponding elements of the outer frame. In a modification, one or more of the side, top and bottom elements of the inner frame may be provided with formations (e.g. ratchet serrations) to interlock with complementary formations provided on the corresponding elements of the outer frame, to prevent withdrawal of the inner frame once fitted into the outer frame.

The window or door assembly itself may be fitted into the frame assembly once the latter is installed. Instead, the window or door assembly may be fitted to the outer frame before the latter is fitted, or may be integrated with the outer frame.

In some cases, the outer frame need not require its peripheral flange. Accordingly, also in accordance with the present invention, there is provided a window or door frame assembly, which comprises an outer frame for fitting into a window or door aperture of a wall, and an inner frame for fitting into said aperture from the inside and to fit within or abut said outer frame, said inner frame having a peripheral flange for seating against the inner surface of the wall around said aperture.

Embodiments of the present invention will now be described by way of examples only and with reference to the accompanying drawings, in which: FIGURE 1 is a side view of the inner and outer frames of a frame assembly in accordance with the present invention; FIGURE 2 is a sectional view through the inner and outer frames shown in Figure 1; 30FIGURE 3 is a sectional view showing the inner and outer frames being fitted into a window aperture in a wall; FIGURE 4 is a similar view showing the inner and outer frames once fitted into the window aperture; FIGURE 5 is an isometric view showing the outer frame being fitted into the window aperture; FIGURE 6 is a similar view showing the inner frame subsequently being fitted into the window aperture; FIGURE 7 is an enlarged sectional view showing the inner and outer frames fitted into the window aperture, these frames being of modified form whereby they interlock.

Referring to Figures 1 and 2 of the drawings, there is shown a frame assembly for a window or door, the assembly comprising an inner frame 10 and an outer frame 20. The inner frame 10 comprises opposite sides, top and bottom elements, each in the form of a panel which is generally flat and of uniform thickness, and a peripheral, outwardly-directed flange 12. The bottom element of the inner frame is formed with a projecting ledge 14. The outer frame 20 also comprises opposite side, top and bottom elements, each also in the form of a panel which is generally flat and of uniform thickness, and a peripheral, outwardly-directed flange 22. The bottom element of the outer frame is formed with a projecting ledge or sill 24. The inner frame 10 is smaller in cross-sectional size, so as to fit, in interference manner, within the outer frame: in particular, the outer frame 20 has a subsidiary frame 21 on its inner faces, providing a rearwardly-facing recess or socket to receive the edges of the inner frame 10.

As shown in Figures 3 to 6, the outer frame 20 is arranged to fit, from the outside, into a window aperture A in a wall W. so that its peripheral flange 22 seats against the outer vertical surface of the wall, around the aperture A. Likewise, the inner frame 10 is arranged to fit into the window aperture A from the inside, also fitting into the outer frame in interference manner, specifically into the recess or socket 23 provided between the inner faces of the outer frame, and its subsidiary frame 21 with its peripheral flange 12 seating against the inner vertical surface of the wall W. Preferably sealing composition is applied to the flanges 12, 22 of the frames before these are fitted into the window aperture: a seal 25 may be provided on the rear of the flange 22 of the outer frame; a seal 13 may be provided onthe outer faces of the inner frame 10 or on the inner faces of the outer frame 20. The outer frame 20 may be fitted from within the building, by passing it through the aperture A, then turning into the correct orientation and pulling it back into position. The outer frame 20 can be aligned, if necessary, using wedges, and fixed in position using screws passed through one or more of its planar side, top and bottom elements into the brickwork. The inner frame 10, once fitted in position, can be fixed using screws S passed through one or more of its side, top and bottom elements and into the corresponding elements of the outer frame, which it overlaps. Foam filler may be injected into the space between the brickwork and the periphery of the inner frame 10, through one or more holes in the side, top or bottom elements of the inner frame.

As shown in Figure 7, the inner frame 10 may interlock with the outer frame 20, upon fitting the inner frame into position. Thus, the outer periphery of the inner frame 10 may be formed with a series of ratchet serrations 15 for co operating with a complementary series of ratchet serrations 25 on the inner periphery of the outer frame 20.

It will be appreciated that the frame assembly which has been described is of simple construction and straightforward to install. Once the frame assembly has been fitted, whether into a window aperture or a door aperture, the window or door assembly itself is fitted into the frame: alternatively, the outer frame 20 may be provided with the window or door assembly before being fitted into the wall aperture, or the window or door assembly may be formed integrally with the outer frame.
