Abstract

A thermally broken frame member comprises an extruded aluminium member 2 having inner 4 and outer 6 sides connected by a transverse web 8 and an elongate plastics web 12. The plastics web 12 has recessed edge portions 14 and clip formations 16 which connect with ribs 18 and which with portions 20 of the sides 4, 6 define open channel formations in which a resin mass 26 is formed by curing a liquid resin therein. Thermal breaks 24 are formed in the channels in the web 8 by casting a settable resin and finally cutting a gap 30 in the metal. <IMAGE>

Description

SPECIFICATION Thermally broken frame member This invention relates to a thermally broken frame member for use in the manufacture of doors and windows and like purposes.
It is well known that hollow metal frames conduct some heat between the inner and outer sides which may cause undesirable condensation on the inner surface under certain conditions. To alleviate this problem, it is known for example, from UK Patent 2060750, to provide a hollow frame member having two spaced apart integral connecting webs, each of which forms the base of a channel extending between the inner and outer sides of the frame member, upon which a sequence of filling and cutting operations is performed to provide a thermal break in each of the connecting webs.
In the known method it is necessary to carry out a cutting operation on each web and to provide a thermally insulating bridging strip over at least one of the slots formed by the cutting operation.
This invention provides a thermally broken frame member as claimed in Claim 1 hereof.
The use of a plastics web member reduces the number of cutting operations required, and the need for bridging a previously debridged channel is avoided.
During manufacture of the frame member as claimed a liquid resin material is poured into each of the channel formations defined between the recessed sides of the plastics web and the sides of the frame which, when cured, locks the assembly together.
The inner and outer sides of the frame and the plastics web are preferably each provided with a keying formation which is at least partially embedded in the resin material in each of the channel formations. This arrangement provides a strong mechanical joint. Retaining means may be provided on the plastics web member to cooperate with complimentary means provided on the inner and outer sides of the frame whereby the plastics web may be retained during the filling of the channel formations with liquid resin material.
To facilitate assembly each side edge of the plastics web may be provided with a resilient clip formation each of which cooperates with a complimentary formation provided on the inner and outer sides of the frame member.
This arrangement has the advantage that the plastics web can be pressed into a position in which it is retained.
One or more other webs may be formed initially integrally with the inner and outer sides of the frame, each such integral web having at least one longitudinally extending channel, the or each channel being filled with an insulating resin and a longitudinal slot being formed in the base of the or each channel to provide a thermal break therein.
In order that the invention may be more clearly understood one embodiment will now be described by way of example only with reference to the accompanying drawings in which Figure 1 is a cross section of a thermally broken frame member and Figure 2 is a cross section of the thermally broken frame member shown in Fig. 1, at an intermediate stage of production.
Referring to the drawings, an aluminium alloy extruded frame member 2 has an inner side 4 and an outer side 6 initially connected together by an integral web 8 (Fig. 2) which is formed with two longitudinal channels 10.
An elongate plastics web member 12, having recessed side edges 14 and a resilient clip 16 along opposed edges is retained by means of clips 16 between the opposed ribs 18 projecting inwardly from the frame sides 6 and 4.
Prior to web 12 being retained in the position shown in Fig. 2 the channels 10 in web 8 are filled with a liquid resin material to provide a cured resin mass 24.
As may be seen, each recessed side edge 14 of web 12. together with the associated rib 18 and side portion 20, provides a channel formation indicated generally by numeral 22 in Fig. 2. The channels 22 are filled with a liquid resin material to provide a cured resin mass 26. Keying formations 28 are provided on the inner and outer sides 4, 6 and on the plastics web 12 to provide a key with the resin mass 26.
The frame member as shown in Fig. 1 is then completed by providing longitudinal slots 30 in the base of each channel 10 to provide a thermal break between the inner and outer sides 4, 6.
1. A thermally broken frame member having inner and outer side portions inter-connected by a plurality of thermally broken webs, characterised in that at least one of the webs comprises an elongate plastics member having recessed side edge portions to define, respectively, with the inner and outer sides of the member longitudinal channels formations which are filled with resin material to lock the assembly together.
2. A frame member as claimed in Claim 1 wherein the inner and outer side portions and the elongate plastics web member are each provided with a keying information at least partially embedded in the resin material.
3. A frame member as claimed in Claim 1 or 2 in which each side edge portion of the plastics web member has a resilient clip formation each cooperating with a complimentary formation provided on the inner and outer side portions of the frame member respectively.
4. A frame member as claimed in Claim 1,

Referring to the drawings, an aluminium alloy extruded frame member 2 has an inner side 4 and an outer side 6 initially connected together by an integral web 8 (Fig. 2) which is formed with two longitudinal channels 10. An elongate plastics web member 12, having recessed side edges 14 and a resilient clip 16 along opposed edges is retained by means of clips 16 between the opposed ribs 18 projecting inwardly from the frame sides 6 and 4. Prior to web 12 being retained in the position shown in Fig. 2 the channels 10 in web 8 are filled with a liquid resin material to provide a cured resin mass 24. As may be seen, each recessed side edge 14 of web 12. together with the associated rib 18 and side portion 20, provides a channel formation indicated generally by numeral 22 in Fig. 2. The channels 22 are filled with a liquid resin material to provide a cured resin mass 26. Keying formations 28 are provided on the inner and outer sides 4, 6 and on the plastics web 12 to provide a key with the resin mass 26. The frame member as shown in Fig. 1 is then completed by providing longitudinal slots 30 in the base of each channel 10 to provide a thermal break between the inner and outer sides 4, 6. CLAIMS
