V;
2 This invention relates to joinery, more particularly to building joinery, including windows, doors, vents and similar constructions arranged to provids closures for openings of buildings.
1AC(gJROUND-TO THE I-NVENR= The present invention, whilst not limited thereto, has particular application to joinery intended for buildings where relative high temperature differences can exist between an Interior and exterior of a building, such as In colder climates, particularly in colder relatively humid colder climates.
The invention also has special application to join"r requiring a high level of aesthetic character, for example as often required in higher quality buildings. certain cormmial applications and according to architectural specification.
Traditionally, joinery and joinery componentry for buildings has been formed in a variety of materials including timber, metals (particularly steel and aluminium), together with certain plastics. Each of these materials incorporate certain inherent advantages, unfortunately also coupled withinherent disadvantages, typical to the materials involved; for example timber, whilst having usually highly desirable aesthetic properties, particularly on an Interior of a building carries with it the disadvantages of manufacturing cost, high maintenance costs and In some instances a lack of weatherlines/durability.
The more commonly used aluniniurn joinery, whilat often able to technically provide the approriate performance aspects desired and meet cost criteria, is often regarded as lucking in the desired sahetic properties. lFurthermore ouch joinery Is often assaoclate with problems connec-ted with heat conduction and related heating and condensation control difficulties.
Plastics. for example extued PVC secrtion manufactured joinery,' 3 whilst providing intrinsic insulation and moderate cost advantages, is oftsn associated with compromised mechanical Iparticularlv rigidity) properties, together with some perceived durability and aesthetic disadvantages.
Logically, attempts have been made to ameliorate these problems by providing joinery which includes combinations of the best feature, of known joinery constructions and materials however, such combination or composite" joinery designs and constructions have often bean found to be in themselves compromised, for example in cost; in view of the fact that often joinary manufacturers and fabricators are primarily set up and have staff skill sets predominantly for one material type form of joinery and do not readily adapt to composite manufacture, resulting in cast and quality problems.
Further, the performance of composite joinary is often compromised, particularly at an interface between the combined joinery construction a..15 materials, for example in condensation entrapment and the downstream deleterious effects on exposed joinery portions.
Composite joinery, by its very nature involves the interconnection of differing materials, with differing performance characteristics, such as thermal co-efficients of expansion and the like. These differences have led to diff icutlis in secure attachment of the differing components and a potential exposure to customer claims, ongoing maintenance, costs and other market difficulties, to say nothing of customer satisfaction.
It is an object of this invention to come some way In overcoming the ebovernentioned problems, or at least provide the public with a useful choice. Other objects ot this invention will! become apparent from the following description.
4 8OA12 101CRIPEiON QF THE~ PBMMENT According to a further aspect of this invention, there is provided a joinery construction incorporating an outer portion capable of building exterior exposure, an inner portion capable of inner building exposure, characterised in that at least a majority of said outer portion is formed inmtra tyehan hra odciiy ihrta aeilfo hc the inner portion is formed, interengaging means provided to juxtapose with, space apart, but mechanically engage substantially parallely aligned parts of said inner and oter portions, an least one parallely aligned part of A. 10 said outer portion and/or said inner portion overlapped with a juxtaposed portion of said interengaging means to maintain said engagement.
Other aspects of this invention will become apparent from the following description which is given by way of reference to the preferred embodiment.
D)ESCRIPTION 9F THE PREFUMIE gmBODIMiNT inReference is made to Figures 1 and 201f the accompanying drawings inwhich.
Figure 1 is a substantially diagrammatic cross-sectional side elevation through a typical Joinery head framne and opening sash combination In the preferred embodiment where the composite join"r is. formed in a combination of aluminium alloy extrusions to an intended building exterior, and timber to an intended building interior.
Figure 2 is a smnla view to that of Figure 1 with the exception that the alternative embodiment is shown as a cross-section through a sill and with fixed glazing.
Referring to the drawings, paticularly Figure 1. the joinary as generally indicated- by arow 1 in the preferred form, but not exclusively, includes a frame porton as generally indicated by arrow 2 and a sash portion as generally indicated by arrow 3.
'CI
The frame portion 2 is suitable for mounting within a rough opening RO of a building suitably supported by packing or wedging W material.
Facing portions 4 of said frame 2 are in the preferred embodiment arranged to overlap building cladding C in the traditional manner for securement of frame 2 in the rough opening RO of a building, Building inner lining (not shown) is arranged to trim the interior of the building and engage in a recess provided either by an interaction of a jamb liner/architrave combination or alternatively a longitudinal recess provided in the jamb liner I (not shown).
The sash 3 Is preferably moveable relative to the frame 2 to enable opening and closing of the sash 3 relative to a rebate 7 provided In the frame 2, sealing being provided via appropriate gaskets 8 between the sash 3 and opposing frame portions 2 as is shown in Rgure 1.
Alternatively, fixed glazing as shown in Figure 2 may be provided for the frame 2 by mounting a fixed adaptor 5 in the frame rebate 7 or alternatively dispensing with sashladaptor assemblies altogether and providing direct glazing into the rebate 7 of the frame 2 (not shown), according to known techniques.
Throughout this specification, references are made to "inner" and "outer". These are to be interpreted in accordance with a general orientation where "outer" means toward a normally intended exterior of the building with which the joinery is intended to be used and "inner", being in the direction of the intended interior of the building.
Further, where reference is made to the terms "upper" and "lower", these are taken to be relative to the orientation of the drawings of Figure 1 and Figure 2, where the structure depicted is intended to show a crosssection through a head (Figure 1) and a sill (Figure 2) of a joinery construction. It is to be appreciated that in accordance with normal joinery construction techniques, tha similar structure can also be used in jamb and head configurations.
8 Referring particularly to Figure the joinery construction incorporates both frame 2 and sash 3 portions of a conmpouite configuration where portions normally in use exposed to an outer portion of the joinery construction including, but not essentially, both the frame 2 and sash 3 directly or indirectly, are formed in aluminium alloy extrusion, whereas, inner portions of said joinery construction I are formed in a material having a higher inaulative property than aluminium alloy and preferably timber- With reference to Figure 1, frame 2 and sash 3 outer portions generally indicated by arrow 10 and include portions of the sash 3 directly exposed to the exterior in use in a building, thote portions which are indirectly exposed (for example by heat conduction and the like including the frame recess 7 abutment 9 and further portions 12 of the sash forming part of the general sash 'extrusion' as depicted).
Outrportions also include frame 2 portions directly or indirectly exposed to the exterior of the building, including the facing portion 4, rebate forming portions 7 and for example, flange portions 13 provided for securement of the frame 2 or within the building rough opening RO.
Inner portions 11 of the joinery construction are in the embodiment depicted in Figure 1 provided as portions of timber 14 applied to the Sash 3 t rvd h ne xoe ufc o h ah3adtejm ie o the frame 2.
'Indirectly interior facing' parts 10 at the cuter portions 10 of the sash 3 and frame 2 (in thea case of the embodiment of Figure 2 the adaptor incorporate an abutment face against which the inner portions 11 may I "25 abut. The sash portion 3 preferably includes inwardly directed elongate rib I1I which asiat seourement of the inner portions 11 thereto.
An Inner edge portion 1 7a of the rib 17 is preferably orthogonally flanged so as to provide a recess generally indicated by arrow 18B into which correspondingly shaped portions of an interengaging member or gasket 9 engage in a longitudinally overlaped assembly. Furthermore,
I-.
7 adjacent edge portions of the timber inner portions 11 applied to the sash 3 are correspondingly shaped and grooved so as to fit in an overlapping relationship with the interengaging member 19 with parallely aligned parts thereof each longitudinally overlapped. The adjacent outer frame portions 10 with the interengaging member 19 and the inner frame portions 11 with the interengaging member 19. In this way it will be appreciated that the longitudinally overlapped assembly assists to securely connect those portions together as effectively one composite building element.
Suitable fixing means, for example screws 20 and the like are 10 provided at regular intervals through the sash 3 outer portion 10 into the sash inner portion 11 to cooperatively maintain a secured attached relationship composite sash 3 element.
In the preferred form of the invention the interengaging means 19 or gasketing means is preferably provided as an elongate strip of thermally 15 insulative material, for example plastics, such as PVC and the like which preferably incorporates substantially moisture transmittal resistance properties. In the preferred form of the invention, preferably the gasket 19 is arranged of a shape length and size so as to correspond with the elongate portions of the sash 3 and frame 2 so that the gasket 19 can be positioned between the inner and outer portions of the sash 3 and frame 2; in this embodiment, between the timber and metal of the inner and outer portions 11 and It will be appreciated that the interengaging means or gasket 19 in providing a substantially moisture resistant barrier will effectively control the passage of any moisture through condensation and the like which forms on the inner face of the sash 3 and frame 2 outer portion 10 and will prevent such moisture contacting directly the timber inner portions 13 thus resisting an otherwise tendency for such moisture to cause damage, for example rotting and the like in that area.
Whilst described with reference to the sill configuration of Figure 2, it will be appreciated that in the sill assembly of both embodiments described 4 8 with reference to Figures 1 and 2. a recess 21ils provided betwean opposed portions of teinterengaging means ISand adjacent portions of the flange 17 so that when the whole section is positioned in the sill orientation as is shown by Figure 2, it will be appreciated that the recess 21 enclosed by opposing portions of the intereng aging member 19 and the flange portion 17 is provided to collect any liquid resulting from condensation which may occur on the surface of the outer frame portion opposing the interengaging member 1 9 or gasket.
In the preferred form of the invention, suitable ports 22 are provided at intervals through the wall of the outer frame portion 10 (for example through The adaptor 5 as shown in Figure such that any condensation created will drain to the exterior.
Iti to be appreciated that any liquid of condensation will be relatively minimal as a result of the substantially enclosed nature of -the inner surfaces of the outer frame portion 10 normally liable to condensation.
C. Furthermore, the flanged nature of the engagement of the flange 17 and interangaging member 19 in the overlIapping relationship further serves to reduce the opportunity for moisture inl the recess draininig other than as described hereinbetore. In this way it will be seen that the normally less durable inner frame portions 11 are reduced in their exposere to moisture of condensation, arm secretly secured and are arranged in a manner which also restricts the exposure of the inner surfaces of the outer frame 10 to -exposure to damp air, thus reducing the opportunities for condesation and heat conduction to occur, all whilst providing beneficial aesthetics.
Referring to both Figures 1 anid 2. it will be appreciated that the owfiguration of the frame 2 rebate 7 and in particular, the height of an uppe portion 7a of an upstand forming portion 9 of the rebate 7 Is osuitiorned sufficie-itly out of register with the timber innr portion 14 of the sash 3 or adaptor 5 such tht a seal 8. may readlily position therein, thus effectively separating the portions; of the frame 2 and sash oute portionsi frorn the interior of Thejoinety when it is in a closed condition.
It will be appreciated that th asemblies of both Figures 1 and 2 in he&% conduction through th joinery adtherefoe the Cetnlcoo of condensation and "chilling', through the joinery.
Whilst the invention has been described with reference to a preferred embodiment incorporating double glazing, the invention is not limited I thereto, and In alternative embodiments of the invention, single. or alternative multiple glazing arrangements may be provided, I .it will appreciated that in assembly of both the preferred the joinery manufacturer provides elongate elements for the join"r 1 of the required length and configuration for normal jointing techniques, for example butt and mitre joints. During assembly, inter engagement of the inner and outer frame portions with one another is attended to much that te joinery can be readily and simply constructed into the composite farm and configuration as described wihreference tothe drawings.
In particular, it will be appreciated that convenient assembly of the inner and outer portions, particularly the inner portion 11 with the outer sash or adaptor portions Carn be achieved by readily eliding preformed and precut Inner portions 1 1 into assembly with final adjustmnens being carried *.20 out after assembly and securement of the outer frame portions with one another, so so to achieve a high level of joint accuracy and other quality control.
in the preferred embodiment of the invention, it wilg be appreciated that the assembly provides simple, and secure attachiment of the inner 2S frome portions with the outer frame portions however in a manner which facilitates removal of the inner frame portions; from the outer frame portions without necessarily requiring disaasembly of joints formed in t or frame portion, for example, should any remedial maintenance or other work be required, given that timber is generally less duirable than other commonly used joinery materials.
Overall, it will be appreciated that the joinery configuratio ns as described hereinbefore with reference to Figures -I and 2 facilitate the convenient and efficient construction of composite joinery incorporating perceived advantages of the materials used and in particular, facilitating preferred aesthetic pcope rtiea often thought to be achieved in some joinery configurations, whilst maintaining other performance attributes required.
Whilst the invention has been described by way of example and with reference to typical *window" configurations, it is to be apprecisad that the invention is not limited thereto and is applicable to all forms of joinery including doom, 1 windows, vents and the like.
