Description
Improvements Relating To Windows The present invention relates to windows and in particular to window frames.
Window assemblies comprising a main frame which is fitted in an opening in a wall of a building and a sash mounted to the main frame are known. Usually the sash is mounted to the main frame for movement between an open position and a closed position by means of sliding or pivotal movement or a combination of the two, though it is also known to have window assemblies in which one or more sashes are fixed in a main frame. In known arrangements, the sash includes a frame which is adapted to receive a glazing unit and a glazing bead which clips to the frame to hold the glazing unit in position against an abutment on the frame. The glazing unit may be a single pane of glass or a sealed unit comprising two or more parallel panes of glass.
Both the main frame and the sash frame are made up of frame members that may be made of wood but in many cases are profiles extruded from a plastics material such as PVC-U or a metallic material such as aluminium.
PVC-U window frames are widely used but in many instances aluminium window frames are preferred for aesthetic and other reasons. The biggest disadvantage of aluminium as a window frame material is its high thermal conductance. It readily conducts heat, greatly raising the overall U value of a window assembly. The most common solution to this problem is to incorporate a material having a higher resistance to heat transfer in the extruded aluminium profile to create a thermal break between the inner and outer surfaces. l-lowever, this adds to the cost of manufacture and whilst thermal breaks are effective in reducing thermal conduction through the frame, the over all U values achievable are still not as low as for a window assembly having an equivalent PVC-U frame.
Metal clad window frames are also known in which metallic cladding is fitted to a wooden or PVC-U frame. Typically, the cladding is adapted to be a sliding fit on the frame members and is cut into lengths and fitted separately to each frame member either before or after assembly into a frame. This process is time consuming and the end results are not as aesthetically pleasing as a conventional aluminium frame.
There is a need then for an improved window frame, which overcomes, or at least mitigates, some or all of the disadvantages of the prior art window frames.
In accordance with a first embodiment of the invention, there is provided a composite window frame member, the frame member comprising an inner profile S extruded from plastics material and two outer profiles extruded from a metallic material each outer profile being attached to respective side face of the inner profile.
The inner profile may be hollow and may be divided internally into a number of cells. A reinforcing and/or a thermal insert may be located in one of the cells.
The outer profiles may be are clipped or snap fitted to their respective side faces of the inner profile. In addition, each outer profile may be bonded to the inner profile by means of a double-sided adhesive tape.
The frame member may be configured for use in a main window frame of a widow assembly, one of the outer profiles projecting inwardly of the inner profile to define with the inner profile a recess for receiving part of a window sash. The projecting portion of the at least one outer profile may be configured to mount a seal for engagement with the frame of a widow sash in use.
Alternatively, the frame member may be configured for use in a sash frame of a widow assembly, one of the outer profiles projecting inwardly of the inner profile to define with the inner profile at least part of a glazing recess for receiving a glazing unit. The projecting portion of the at least one outer profile may be configured to mount a seal for engagement with a glazing unit in use. The inner profile may comprise a formation for mounting a glazing bead. The frame member may be configured to receive a glazing unit having a width which is smaller than the width of the inner profile.
In accordance with a second aspect of the invention, there is provided a window frame comprising a plurality of frame members in accordance with the first aspect of the invention The frame may be a main frame for a widow assembly or it may be a sash frame for a window assembly.
In accordance with third aspect of the invention, there is provided a window assembly comprising a main window frame in accordance with the second aspect of the invention and at least one window sash having a frame in accordance with the second aspect of the invention.
In accordance with a fourth aspect of the invention, there is provided a method of manufacturing a window frame member in accordance with the first aspect, the method comprising producing an elongate extrusion of a plastics material to form the inner profile, producing first and second elongate extrusions of a metallic material to form the outer profiles, attaching the first and second outer profile extrusions to respective side surfaces of the inner profile extrusion and cutting the resulting composite to the required length.
The step of attaching the first and second outer profile extrusions to respective sides of the inner profile extrusion may comprise clipping the outer profile extrusions to their respective side surfaces of the inner profile extrusion.
The step of attaching each of the first and second outer profile extrusions to the inner profile extrusion may comprise affixing a length of double-sided adhesive tape to a surface of one of the inner profile extrusion and the outer profile extrusion, attaching the outer profile extrusion to the inner profile extrusion to bring an exposed surface of the tape into contact with a corresponding surface on the other of the inner profile extrusion and the outer profile extrusion.
In accordance with a fifth aspect of the invention, there is provided a method of manufacturing a window frame, the method comprising producing a plurality of frame members of desired lengths in accordance with the method of the fourth aspect and assembling the frame members together to form the frame.
An embodiment of the invention will now be described, by way of example only, with reference to the drawings in which: Figure 1 is across section through a frame member forming part of a main window frame of a window assembly.
Figure 1 shows a lateral cross section through a composite frame member 10 forming part of a main or outer frame of a window assembly. The frame member comprises an inner profile 12 and two outer profiles 14, 16, each outer profile 14, 16 being mounted to a respective side face 18, 20 of the inner profile.
The inner profile is an extruded profiled element made of a thermoplastics material such as PVC-U and forms the main structural component of the frame member 10. The inner profile is hollow and is divided internally by walls 22, 24 into thee hollow chambers 26, 28, 30 to give the inner profile a required level of structural rigidity. The exterior of the inner profile is provided with various protrusions 32 for attaching the frame member within an opening in a wall of a building or the like.
A thermal insert 34 is located within a central chamber 28 of the inner profile 12. The insert 34 is a hollow member which is of a corresponding shape and similar dimensions to the central chamber 28. As shown in Figure 1, the thermal insert 34 sits within the chamber 28 with minimal clearance between it and the walls of the chamber 28. It should be understood, however, that the thermal insert 34 could also be of a smaller dimension than that of the central chamber 28 so that the insert only partially fills the chamber 28. The thermal insert 34 is elongate and may extend along the entire length of the inner profile. The thermal insert 34 is manufactured of a material such as PVC-U having a low thermal conductivity and is configured to act as a thermal barrier to reduce the transfer of heat across the frame member. As shown in Figure 1, the thermal insert is divided internally into a number of internal cells 34 aligned in a lateral direction of the frame member profile. Each of the cells acts as a thermal barrier to reduce the conduction of heat across the frame member. Alternative designs for the thermal insert are possible. For example, the insert 34 could have a hollow body filled with a thermally insulating material such as expanded foam.
The thermal insert is not essential to the invention and could be omitted altogether or replaced by a reinforcing insert configured to increase the strength and rigidity of the inner profile 12 and hence the frame member 10 without providing a thermal barrier. For example, a reinforcing insert could be in the form of an elongate metallic member of channel or hollow box section dimensioned to fit snugly in one of the chambers 26, 28, 30, typically the central chamber 28.
The two outer profiles 14, 16 are elongate extruded profiled elements made of a metallic material. En one embodiment the outer profiles 14, 16, are extruded from aluminium or aluminium alloy. For ease of reference, the term "aluminium" will be used herein but it should be understood that references to "aluminium" are intended to encompass aluminium alloys.
Each of the outer profiles has a pair of spaced, elongate clip members 36, 38 which project from an inner surface for engagement with a corresponding pair of clip formations 40, 42 on a respective side face of the inner profile. The clip members 36, 38, 40, 42 have co-operating head portions which enable the outer profiles to be firmly secured to the inner profile with a clipping or snap-fit action by pressing the outer profiles into engagement with the inner profile in the direction of arrows A and B until the head portions of the clip formations engage as shown in Figure 1. The outer surfaces of the head portions are angled to facilitate engagement.
For added security, the outer profiles 14, 16 can be bonded to the inner profile.
In a convenient embodiment, the outer profiles are bonded to the inner profile by means of a length of double-sided adhesive tape 44. The inner profile 12 has an outer surface region 46 on either side between the clip formations 40, 42. Each outer surface region 46 is configured to lie in close proximity to the inner surface 48 of the respective outer profile 14, 16 when the outer profiles 14, 16 are affixed to the inner profile. Prior to assembly of the outer profiles to the inner profile, a length of double-sided tape is affixed to each of the surface regions 46 on the inner profile. When the outer profiles 14, 16 are clipped to the inner profile, the exposed surface of the tape contacts and adheres to the inner surfaces 48 of the outer profiles 14, 16. It will be appreciated that the lengths of double-sided tape could be initially affixed to the outer profiles 14, 16 rather than to the inner profile 12 if desired.
The outer profiles 14, 16 are shaped to fully cover their respective sides of the inner profile 12 and to provide a facia with an aesthetically pleasing aspect. A first one of the outer profiles 14 projects radially inwardly of the inner profile 12 so as to define with the inner profile a recess 50 for receiving the frame of a window sash (not shown). The projecting part 52 of the first outer profile 14 acts as an abutment against which the sash frame can be brought into contact when the sash is in a closed position relative to the main frame. The abutment 52 is provided with a formation or recess 54 for mounting a seal (not shown) for contact with the sash frame in a known manner.
Four or more frame members 10 of suitable lengths can be assembled together to form a main window frame in a manner known in the art. In a preferred method of manufacture, elongate extrusions for forming the inner profile 12 and the outer profiles 14, 16 are produced. The outer profile extrusions are then assembled to the inner profile extrusion using the double-sided tape 44 and the resulting composite is then cut to produce frame members 10 of the desired length. The frame members 10 can then be assembled into a frame. Typically, the frame will have a rectilinear shape and the ends of the frame members 10 will be mitred and welded together. Where a thermal or reinforcing insert 34 is required, this can be produced and inserted into the inner profile extrusion before the composite is cut to produce individual frame members of the required length.
It will be appreciated that the overall shape of the frame member 10 and the shapes of the inner 12 and outer profiles 14, 16 can be varied from those shown in Figure 1, which is only an example of a typical arrangement suitable for use in a main window frame.
Whilst the invention has been described with reference to a frame member for a main or outer window frame, it will be appreciated that the same principles can be applied to a frame member for window sash frame. In a typical widow assembly, it is desirable for both the main fame and the, or each, sash frame to have the same appearance and this can be achieved by manufacturing both the main frame and the sash frame(s) using composite frame members essentially as described above.
Where a frame member in accordance with the invention is intended for use in a sash frame, one of the outer profiles may project radially inwardly beyond the inner profile so as to form an abutment which defines together with the inner profile a recess for receiving a glazing unit. In addition, the inner profile may be provided with a recess or other formation to which a glazing bead can be attached to secure a glazing unit in position within the recess.
A composite widow frame member 10 in accordance with the invention has the advantage of having the appearance of a metallic, and in particular aluminium, window frame, whilst a significant part of the internal structure is formed by means of a plastics, and in particular PVC-U, extruded profile. As a result, the thermal resistance to conductivity across the frame member is much higher than that of an aluminium extruded frame member and is even higher than known extruded frame aluminium frame members which incorporate a conventional thermal break.
Consequently, the overall U value of a window assembly having window frames made up from the composite widow frame members can be kept low. A further advantage is that much less aluminium used in the construction of a composite frame member in accordance with the invention than in an equivalent aluminium frame member, which helps to keep production costs low. However, unlike conventional clad window frames, the outer profiles 14, 16 form part of the structure of the frame member rather than just forming a covering so that the appearance of the resulting window frame is much closer to that of a conventional aluminium window frame.
Whereas the invention has been described in relation to what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed arrangement but rather is intended to cover various modifications and equivalent constructions included within spirit and scope of the invention.
