Description
Window Frames, Window Vents and Manufacture
thereof
This invention relates to a window frame, to a window vent and to the manufacture of said frame and vent.
Plastics window frames, both main frames and sub-frames, are generally made by cutting PVCU extrusions to length and jointing the lengths at the corners of the required frame, which is invariably square or rectangular.
According to one aspect of the present invention, there is provided a method of manufacturing a window frame according to which two partial frames of plastics material are produced by injection moulding, the partial frames being correspondingly square or rectangular and constituting interior-facing and exterior-facing parts of the frame, and the two partial frames are secured together to form a complete square or rectangular window frame.
According to another aspect of the invention, there is provided a window frame which consists of two correspondingly square or rectangular partial frames secured together, the partial frames constituting the interiorfacing and exterior-facing parts of the frame, each partial frame being injection moulded of plastics material.
Although the invention does not exclude main frames for windows and doors, these frames are required to fit into wall openings which, at least in the case of replacement windows, means that main frames may be required in a wide variety of sizes. The present invention, however, is more suited to the production of frames which have a limited number of standard sizes, as is usually the case with window vents.
According to still another aspect of the invention, therefore, there is provided a method of manufacturing a window vent according to which two partial frames of plastics material are produced by injection moulding, the partial frames being correspondingly square or rectangular and constituting the interior-facing and exterior-facing parts of the frame of the vent, and the two partial frames are secured together to hold the window glass between them and thereby form a complete window vent.
According to yet another aspect of the invention, there is provided a window vent which consists of two correspondingly square or rectangular partial frames secured together to hold the window glass between them, the partial frames constituting the interior-facing and exterior-facing parts of the frame, and each partial frame being injection moulded of plastics material.
It will thus be appreciated that the invention, in the case of a window vent, provides the additional advantage that the window glass is readily incorporated into the vent frame on assembly of its two parts.
In all cases, however, the invention provides the possibility of producing a less expensive frame of improved appearance, because the steps of cutting and jointing frame lengths are avoided, and the finished frame does not possess joint lines at the corners.
Preferably, the injection moulded partial frames are produced with a weather-resistant and colour-fast skin and a core of foamed or solid plastics material. The skin may conveniently be formed of UPVC or acrylic plastics material. It is essential for this skin to be colour-fast and resistant to effects of U/V light.
The core may be hollow, and filled with gas on its interior. This gas may be a gas with high thermal insulating properties. In this injection moulded frame, the skin provides only the required surface finish; the gas filled core imparts the required strength to the frame.
Thus, in the injection moulding process, material for producing the skin is first injected into the mould, followed by the material for producing the core and then a gas under pressure which blows the material outwardly towards the walls of the mould cavity. In this way a dense skin is produced, enclosing a hollow gas filled core.
Economy in production of the frames can be achieved by using recycled plastics material to form the core.
The two partial frames are preferably moulded with interfitting parts at which the two partial frames interengage and preferably interlock, most preferably non-separably.
Alternatively or more usually additionally, however, the two partial frames may be secured together by fixing screws, for example passing through at least certain interengaging fittings.
Interengaging fittings could be provided continuously around the partial frames, but preferably a number of spaced interengaging fittings, a plurality on each side of the frame, are produced by the moulding process.
In the case of a window vent, one or other of the partial frames may be moulded with integrally formed hinge and/or handle and/or stay fittings. Additionally, a glazing wedge may be formed integrally with one or other of the partial frames, generally the interior partial frame. A separate glazing wedge may then be forced into position tightly to secure the window glass.
It may also be possible to mould a semi-flexible glazing bead integrally with one or other of the partial frames.
A window vent in accordance with the invention is now described by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a window vent in perspective from the
exterior side;
Figure 2 shows the vent from the interior side;
Figure 3 is a cross-sectional view throat and along one
side of the vent;
Figure 4 is a parallel cross-section through the glasing;
and
Figure 5 is a transverse cross-section through one side
of the frame.
Referring first to Figures 1 and 2, there is shown a window vent 10 produced in accordance with the invention.
The illustrated vent is for convenience of a minimum square size. However, window vents of larger rectangular size can readily be made and differ only in longitudinal frame dimensions in respect of the features described below.
In the drawings, Figure 1 shows the exterior facing-side 12 of the vent 10 and Figure 2 shows the interior-facing side 14.
The interior and exterior-facing sides of the vent frame are constituted by separate partial frames, as later described. However, referring to Figures 1 and 2, it is to be noted that there are no corner joints in the frame.
The interior-facing side 14 has a face 16 (possibly curved) which slopes towards the window glazing 18; the exteriorfacing side 12 has a face 20 which slopes towards the glazing 18 and a peripheral face 22 which slopes towards the interior-facing side. The lines 24 which appear in
Figures 1 to 3 at the frame corners indicate the lines at which two inclined faces meet, and do not indicate joints.
The frame in accordance with the invention does not have corner joints.
Referring now to the cross-sectional view of Figures 3 and 4, the exterior-facing and interior-facing sides 12 and 14 of the frame can be seen. These exterior-facing and interior-facing sides are constituted by partial frames, to which the references 12 and 14 are now applied. The two partial frames 12, 14 have corresponding square or rectangular shapes and are interengaged and secured together, sandwiching the window glazing 18 between them, in order to produce the complete vent.
Figure 3 is a longitudinal cross-section through and along one side of the two interengaged partial frames 12, 14 and Figure 4 is a parallel cross-section through the glazing 18, which is considered transparent to enable the far side of the frame to be seen in the drawing.
The two partial frames 12, 14 are each made by an injection process in which UPVC material (or acrylic or other suitable plastics material which is colour-fast and U/V light-resistant) is first injected into the mould, followed by a core material of any suitable plastics material which may be recycled plastics material, in turn followed by injection of gas under pressure which forces the injected solid material outwardly towards the walls of the mould, thereby to form each partial frame with a dense skin rigidified by a gas filled core. The core material may be a foamed or a solid material, and the gas may have high thermal insulating properties.
For reasons of clarity, the partial frames 12, 14 are shown in Figures 3 and 4 as simple hollow members.
However, a realistic cross-section through the partial frames is shown in enlarged view in Figure 5.
In Figure 5, the UPVC or similar skin is referenced 12A, 14A respectively, the core 12B, 14B respectively, and the pressurised gas filled space within the core is referenced 12C, 14C respectively.
Additionally, the partial frames 12, 14 are moulded with fittings 26, 28 respectively, of plastics material, at which the two partial frames interengage. The fittings 26, 28 are as shown in Figure 5 formed of the plastics material forming the skin, but this is not essential.
The moulding process can be carried out in such a manner that, provided the core is a solid as distinct from foamed material, it is the core material which produces the required fittings. In this connection it will be appreciated that the fittings are hidden in the assembled complete vent.
The moulded fittings 26 on the exterior partial frame 12 comprise box-like formations. The moulded fittings 28 on the interior partial frame 14 comprise spaced fins which engage into the said box-like formations.
At least some of the fins 28 have integral enlarged heads 30 which lock into recesses 31 in the walls of the boxlike formations 26, so that the two partial frames 12, 14 interlock into non-separable engagement. Additionally, however, and referring specifically to Figure 4, it can be seen that certain interengaging fittings 26, 28 are also fixed together by fixing screws 32, so that in the finished vent 10 the two partial frames 12, 14 are completely immovable relative to one another and the complete unit, as seen from the interior or exterior, is virtually indistinguishable from a one-piece moulding.
The interengaging fittings 26, 28 are spaced around the frame, with a plurality of such interengaging fittings on each side.
In Figure 4 can also be seen glazing wedges 34 which are integrally moulded into the inner peripheral surface of the interior partial frame at the end regions of its sides.
The window glass 18 is trapped between the parts 36 and 37 of the two partial frames when said partial frames are interengaged. After securing the two partial frames 12, 14 together with the glazing 18 sandwiched between them, separate glazing wedges (not shown) can be driven into place to cooperate with the glazing wedges 34 and thus secure the glass tightly in place.
Additionally, as again shown in Figure 4, fittings 38 for hinges may be integrally moulded into the outer peripheral face of the exterior partial frame. Such fittings would be provided only on one side of the frame, the vertical side in the case of a side hung vent. nnalogously, fittings for receiving a handle and/or window stays may be formed by the moulding process on the opposite side of the frame, as indicated at 39.
For completeness, Figure 3 also shows the way in which the window vent 10 abuts the main frame 40 in the closed position. Manufacturing the window vent by the injection moulding process described can enable a larger overlap to be obtained of the peripheral edge of the vent 10 over the peripheral edge of the main frame 40. The illustrated main frame is a conventional extruded UPVC main frame, but it is possible for the main frame also to be produced by injection moulding, for example in accordance with the present invention.
