Detailed Description of Preferred Embodiments The problems previously raised in relation to wings (and in particular screen doors and window screens) raise the possibility of designing a wing that is configurable to suit openings of different widths and/or different heights and further of being adaptable to suit different common openings within a territory and to have a screen that is resistant sagging. Such adjustable wings could be manufactured without reference to particular openings

17864239_1 (GHMatters) P107305.AU.2

(which is time consuming and expensive) and by modern manufacturing methods and systems. Notwithstanding that some of the inventions within are described with reference to the wings shown in the figures, they are not limited to such wings. COMPETING DESIGN CONSIDERATIONS It is desirable for the frames of many wings to have minimum widths and depths for aesthetic reasons and also to minimize material costs; this is particularly true for doors and screens. However, other competing considerations may impact on the sizes that frames may employ, including: the width of frame members needs to be to be large enough to adequately overlap the infill-edging when the wing has been adjusted to the largest pre-determined size; in some doors (including conventional Australian security doors), the closing edge frame member needs to accommodate an industry standard lock body and so includes a hollow having a depth substantially 16MM; some embodiment of the inventions need to provide a wings that embrace all the common sizes encountered in Australia, and where doors to embrace conventional Australian metric doors and conventional Australian imperial doors;

in some doors including conventional Australian security doors, the closing edge frame member (of a closed wing) needs to abut a door-stop while overlapping an opening frame member that supports a strike plate; this configuration enabling a lock bolt of the lock to engage with the strike plate - all of which is well known and common practice; the frame, infill-edging and infilling portion together must provide a structurally sound wing sufficiently robust for the intended purpose; all fasteners whose removal would compromise security, must be inaccessible when the wing is in a closed configuration; for reasons including aesthetic reasons, the infilling portion should be maintained in a substantially planar form and should be biased against sideways displacement which might take the form of flopping or wrinkles in the infilling portion. TWO EMBODIMENTS The inventions described herein include wing 1 including a frame 3 including frame members 11 that extend longitudinally to at least in-part define the edges 183 of the wing and are relatively displaceable to change the shape of the wing, each said frame member connected to other frame members by means including corner connectors 43 and each adapted to include a laterally elongated side-channel 6 that extends longitudinally and

17864239_1 (GHMatters) P107305.AU.2 alongside the corner connectors 43, and an infilling portion 8 that extends laterally between frame members 12, 13 and is defined in-part by opposed sides 181, 182 and a peripheral edge 20 that is retained relative to the side-channel 16 of each frame member. In a first embodiment referencing Fig 1 to 32 and Fig 1 to 19 in particular in particular, each frame member comprises an elongated hollow thin-walled member having a substantially rectangular cross-section defined in-part by an interior side wall 14 and an exterior side wall 15 that also forms one of the walls that define in-part the elongated side channel 16 that is further defined in-part by a longitudinally elongated side-fin 17 extending alongside the exterior wall 15. In a second embodiment referencing Fig 1 to 32 and Fig 20 to 32 in particular, where each frame member comprises an elongated hollow thin-walled member having a substantially rectangular cross-section defined in-part by an exterior side wall B15 and a wider interior side wall B14 that also forms a wall of the elongated side-channel B16 that extends laterally beyond the exterior wall B21- this frame being less deep and although not restricted to, is particularly well suited to window screens.

FIRST EMBODIMENT INFILLING PORTION In some forms the frame members 11, 12, 13 are relatively positioned such that the respective side channels 6 together form a substantially continuous uninterrupted side channel16. In some forms, referencing Fig 2, 6, each frame member 11 is adapted to include a side-fin 17 that extends to form a substantially U shaped side-channel between the exterior side wall 15 of the frame and the side-fin 17; this side-channel comprising the side-channel 6. In some forms, the infilling portion 8 is comprised of material that is substantially inextensible and therefore resistant to stretching. In some forms, it is substantially planar, inextensible but bendable but when supported as described below, it is resistant to bending and substantially resistant to shearing within the plane that substantially defines it. In some such forms it comprises perforated sheet metal 121 or woven steel mesh 120 that in some forms comprises woven 304 S/S or 316 S/S wire and in some forms, having a diameter between 0.7 and 0.9MM. In some forms the infilling portion 8 would be manufactured by processes including cutting to size, slitting and laser cutting to exactly position the holes for studs 71 (described below) - all of which is well known.

17864239_1 (GHMatters) P107305.AU.2

In some forms, referencing Fig 10, the infilling portion 8 includes material that is substantially rigid (it being unable to bend or skew) and in some such forms it comprises glass sheet 122. Experience has shown that unless an infilling portion 8 (that is inextensible but bendable) is well supported along its peripheral edge 20 and held tensioned it may become "loose and floppy" and able to displace sideways in response to displacement of the wing, attack or even wind. Some door manufacturers address this issue by inwardly deforming the frame 3 while the infilling portion 8 is being attached and then releasing the frame 3 to exert outwardly directed forces along the peripheral edge 20; these forces acting to restrain the infilling portion against sideways displacement. These outwardly directed forces also urge the infilling portion 8 against skewing as described below. In other less desirable cases, the infilling portion is supported along its peripheral edge 20 without being tensioned and when the frame incrementally skews or the infilling portion incrementally deflects sideways, outwardly directed reactionary forces develop along the peripheral edge which act to oppose further skewing and/or deflection. By way of example only, consider a substantially rectangular wing, referencing Fig 1 and 2, where the infilling portion's peripheral edge has been adapted to include an infill edging 150 (described below) that includes opposed spaced infill-edging members 25-25 (described below) and opposed spaced infill-edging members 26-26 (described below) and where the infilling portion 8 comprises inextensible but bendable material (that in some forms comprises perforated sheet metal 121 or woven steel mesh 120), held in tension relative to the opposed infill-edging members 25-25, 26-26. Skewing in this context, would result in the longitudinal relative displacement of opposed infill-edging members 25-25 in opposite directions or the longitudinal relative displacement of opposed infill-edging members 26- 26 in opposite directions. Such skewing would require the strands (or virtual strands) of the infilling portion 8 to extend (but this is precluded by them being substantially inextensible) and/or would require opposed infill-edging members 25-25 and/or 26-26 to displace towards each other to allow for example, the horizontal strands of the infilling portion to become angled. However outwardly directed forces (described below) acting along the infill-edging 150 act to oppose this inwards displacement and hence act to oppose skewing. Fixing fasteners 80 may be employed to apply these outwardly directed forces (described below) and these may also act to prevent the infill-edging members 25-25 and 26-26 from displacing inwardly relative to the frame 3 and hence towards each other.

17864239_1 (GHMatters) P107305.AU.2

In some wings, the infilling-edging 150 is acted upon by outwardly directed forces that "well tension" the infilling portion 8 whereby to preclude sideways displacement of any part of the infilling portion 8 in excess of a pre-determined limit and to preclude skewing by forces up to a pre-determined limit. These outwardly directed forces derive from one or more types of interconnecting means that in some forms includes springs 130 (also referred to as spring mechanisms 130) and in other forms include fixing fasteners 80. For convenience and to enable a sharing of components different types of interconnecting means in some wings are located adjacently. Importantly, the interconnecting means accommodate relative displacement of the frame members to allow the frame to change shape as described below. Where the infilling portion 8 comprises glass or the like, the infilling portion is unable to substantially skew and where spring mechanisms are employed, they act to urge the infilling portion against lateral displacement relative to the frame and in some wing configurations, they act to centralize the infilling portion 8 between opposed frame members INFILL-EDGING CONSTRUCTION In some forms of wing 1, the peripheral edge 20 is adapted to participate in an infill edging 150 that in some forms also includes infill-edging members 25, 26 and preferably the channels 6, 16 have a depth which provides minimal working clearance to provide good support for the infilling-edging 150 to restrain it against axial rotation and sideways deflection while not restricting lateral displacement relative to the frame. The infill-edging members 25, 26 together can be thought to provide an inner frame 9 that in some forms comprises a single member in which second infill-edging members 26 are connected at each end to a respective second infill-edging member 25. In some such forms, the infill-edging members 25, 26 (described below) are connected by welding; in other forms referencing Fig 3, each connection comprises a plate 124 that overlaps both the end of a first infill-edging members 25 and the end of an adjacent second infill-edging members 26, the plate attached to each by respective eyelets or rivets 126 that extend through respective coaxial apertures in the ends and the plate. In other forms, the infill-edging members 25, 26 referencing Fig 2, each comprise separate elongated members while in other forms again, they each comprise multiple discrete relatively short members. In some forms, the infilling portion 8 is bendable and able to be bent and in some such forms, referencing Fig 3 and 9, the peripheral edge 20 is configured to extend across the exterior side 28 of a respective infill-edging member 25, 26 (and preferably all) to be

17864239_1 (GHMatters) P107305.AU.2 folded at a first corner to extend along the outer edge 29, to be folded again to extend along the interior side 31 to form a U-shaped return 7; this folding providing greatly enhanced retention of the peripheral edge 20 because of the torturous path the peripheral edge 20 would need to slide over and deform over to separate from the respective infill-edging members 25, 26; this folding around the infill-edging members 25, 26 for ease of description being referred to herein as "wrapping around". Preferably at least spaced portions of the entire peripheral edge 20 are so configured. In some forms, substantially the entire peripheral edge 20 is adapted to include a peripherally elongated U-shaped return 7 that participates in an infill-edging 150 that includes elongated infill-edging members 26, 25 that extend relative to at least the majority of the peripheral edge 20. Where the infill is substantially rectangular the infill-edging members 25-25, 26-26 comprise substantially parallel spaced first infill-edging members 25 and substantially parallel spaced second infill-edging members 26, where the second and first infill-edging members 25, 26 are substantially orthogonally positioned. In some forms referencing Fig 3, the U-shaped return 7 is attached along the interior side 31 by spaced fasteners 32 that may comprise rivets 37 that extend through multiple apertures spaced along the U-shaped return 7. In some forms, the rivets comprise solid rivets having a reduced lead diameter and a shank diameter exceeding the diameter of the respective apertures in which they are inserted to become solidly fixed. In other forms, fasteners 32 are omitted. In some forms, referencing Fig 3 prior to assembly, the infilling portion 8 is intermittently slit along lines corresponding to the bends and folds described above to enable the infilling portion 8 to be more easily/neatly folded In some forms, referencing Fig 2, 6, the infill-edging members 25, 26 comprise longitudinally elongated (straight) bars or strips 10 (having exterior surfaces defined by a common plane) and in some forms they comprising 304 or 316 stainless steel having well known properties that include the ability to elastically deflect under load. In a specific form of the first embodiment, the infill-edging members have a rectangular cross-section that is 5 MM thick and 20 MM Wide. In some alternative forms, each infill-edging member 25, 26 referencing Fig 4, is replaced by alternative infill-edging members 66 and 67 comprising elongated aluminium extrusions 215 having a substantially rectangular cross section and having a profiled longitudinally elongated channel 216 that includes ratchet shaped teeth 64 and adhesive 65 substantially as described in Australian patent AU2008 202835. The respective peripheral

17864239_1 (GHMatters) P107305.AU.2 edges 20 of the infilling portion 8 extend into respective channels B216 to be attached there as described in Australian patent AU2008 202835 herein included by reference and as described in the Abstract, reproduced herein as Fig 32. "A method of providing a frame 12......... is performed by engaging an elongate insert 18 of plastics material with one side 16 of an elongate recess 15 in the frame by engaging shaped rib 20 in a corresponding keyhole 050 slot 19. The internal face of the insert 18 is provided with double sided adhesive tape 22 00 positioned such that the edge 11 of the security screen 10 may be fully inserted into the 00 bottom of the recess 15 without contact with the adhesive face 21. The face of the security screen is then forced into contact with the adhesive face 21 by inserting a wedge member 25 having ratchet shaped teeth 27 which engage with corresponding ratchet shaped teeth 24 on the adjacent face of the internal recess . . "

In some simplified forms of the first embodiment, each first frame members 12 and each second frame member 13 are replaced by an alternative first frame member 62 and an alternative second frame member 63 each configured to have an alternative profiled channel 61 that includes ratchet shaped teeth 64 and adhesive 65 substantially as described in Australian patent AU2008 202835. The respective peripheral edges 20 of the infilling portion 8 extend into respective channels 61 to be attached there as described in Australian patent AU2008 202835 herein included by reference and as described in the Abstract, reproduced herein as Fig 32 and the infill edging members 25, 66 and 26, 67 would be omitted. In this cases, the frame members 62, 63 would be displaced (as described elsewhere to change the shape of the wing) after which the peripheral edge 20 would be fixed to the adjacent frame members 22,633. However the method described in AU2008 202835 is adapted such that the protective plastic strip commonly used to separate the adhesive strips from the infilling portion is left in place till the alternative frame has been adjusted to attain the desired shape then protective strips would be peeled off, and the wedge 217 referencing Fig 5 would be driven in. In some cases, the alternative frame would be marginally increased is size after the peripheral edge had been fixed to the frame to well tension the infilling portion. In some forms employing infill-edging members 26, 25, the infill-edging members 25, 26 are flexible and have elasticity properties and are able to deflect within their respective lengths (and hence are able to be outwardly deflected by the interconnecting means described below) and where it is desirable they be maintained in a substantially straight (rectilinear) form, they are preferably supported at multiple points within their respective

17864239_1 (GHMatters) P107305.AU.2 lengths by interconnecting means to maintain any deflection within acceptable predetermined limits. In some forms the infilling portion 8 includes material that is rigid and substantially resistant to deflection and unable to be bent or skewed and in some such forms it comprises glass sheet 122. In some such forms it is supported along its peripheral edge 20 by means including extending into a channel 82 of alternative infill-edging members 25, 26 and in some forms to be retained there by means including adhesive 83; in some forms there are enlarged apertures 214 in the glass to accommodate threaded inserts 127 that are able to engage with studs 71 as described below. In other forms the infilling portion includes other suitable substantially inextensible material.

FRAME In some forms referencing Fig 6 to 7, the frame 3 comprises elongated hollow frame members 11 that extend relative to (to help define) the respective edges 183 of the wing, In some wings they are connected by corner joints 40 including respective corner connectors 43 referencing Figs 11 to 13 and 16, together to comprise a continuous articulated frame 3. In some forms, referencing Fig 6 to 7, each frame member 11 has a substantially rectangular cross-section including a substantially rectangular hollow 19, an outer edge wall 21 connected to an opposed inner edge wall 22 by an exterior side wall 15 and an interior side wall 14. Each frame member 11 is adapted to include a longitudinally elongated side-fin 17 that extends laterally to form the substantially U shaped side-channel 6 between the exterior side wall 15 and the side-fin 17; the side-fin 17 extending along the length of each frame member while extending laterally towards the inner edge wall 22; the side-channel 6 defined in part by an lateral opening 140. In the smallest configuration of the wing, the infill-edging members 25, 26 lie in close proximity to the closed end 5 of the side-channel 16. The wing also has a largest configuration where the peripheral edge 20 and/or the infill-edging 150 and/or infill-edging members 26, 25 as the case may be, are displaced from the closed end 5 of the side channel 16 and in some such forms, the infill-edging members 25, 26 are parallel to their respective orientations in the smallest configuration. By way of example only, consider a substantially rectangular infill referencing Fig 1 and 2, where the frame 3 is substantially rectangular and comprises spaced substantially parallel first frame members 12 (that in some wings are substantially vertical) and

17864239_1 (GHMatters) P107305.AU.2 substantially parallel spaced second frame members 13 (that in some wings are substantially horizontal), each first frame member 12 being connected at each end to a respective second frame member 13 by a respective corner joint 40 referencing Fig 11 to 13; in some such forms the side-channel 16 of each first frame member 12 being occupied by a corresponding first infill-edging member 25, the side-channel 6 of each second frame member 13 being occupied by a corresponding second infill-edging member 26. In some forms, the frame 3 referencing 6, 7 comprises a two-part frame comprising: A) a longitudinally elongated first frame member 23 including the substantially rectangular hollow 19, the outer edge wall 21 connected to an opposed inner edge wall 22 by the exterior side wall 15 and by the interior side wall 14 and having one of the pair of fins 18 that define in-part the edge channel 58 and in some forms a side-channel end wall 174 that is able to support an elongated cupped insulator 175 and a longitudinally elongated orthogonal fin 177 extending sideway, and B) a longitudinally elongated second frame member 24 including the side-fin 17 connected to a fin return 173 (that together with outer edge wall 22 form an enhanced outer edge wall 30) by which it is attached to the first frame member 23 and a secondary longitudinally elongated interior fin 176 that extends towards the first frame member 23 to locate adjacent to a longitudinally elongated orthogonal fin 177 extending sideways from the first frame member 23; fins 176 and 177 cooperating to provide support for the wing 17, and C) where each frame member 23, 24 when assembled together provide the substantially U shaped side-channel 6 between the exterior side wall 15 and the side-fin 17; the two portions fixed together and in some forms by fasteners 178 spaced along the fin return 173 to extend through respective coaxial apertures 179 in the outer edge wall 21, the fasteners 178 in some forms comprising (internally threaded) Rivnuts. Hollow rectangular frame members 11 are well suited to and well known in the manufacture of many wings including doors and screens, in some forms they include one or the following: drawn steel tube, extruded aluminium, roll-formed steel, extruded plastic (including pvc) .

CORNER JOINTS Each pair of frame members participating in a respective corner joint are connected by a respective corner connector 43 including a pair of legs 41, 42 each engaged with a respective frame member 12, 13. In the first embodiment the corner is adaptable and the connector 43 is included within a connector 45 comprising a hub 144 and a pair of operable members 48 each extending to engage a respective corner block 52 fixed relative to a

17864239_1 (GHMatters) P107305.AU.2 respective frame member 11, each said operable member 48 operable to displace a respective corner block 52 (and respective frame member 11) away from the hub 144 whereby to change the effective length of the respective frame member whereby to change the shape of the wing - the connector 45 including coaxial apertures 218 for passage of an Alan key into the drive recess of the operable members 80. In some forms, a second leg 42 extends within the hollow 19 of a second frame member 13 and a first leg 41 extending within the hollow 19 of a first frame member 12. In some forms each leg 41, 42 comprises spaced fingers 141. In a substantially conventional mitre joint, the legs 41 and 42 mate with respective hollows 19 with minimal or without clearance to form a rigid joint and the frame members 12, 13 participating in a respective joint are angularly separated by an "included angle" of 90 degrees and the ends of the frame members are angled at 45 degrees to abut along their entire ends. In the angularly adaptable joint, referencing Fig 11 to 13 and 16, the ends 187 and 188 of the first and second frame members participating in a respective joint may be angled at less than 45 degrees to expose a gap 54. The or each leg 41, 42 is able to angularly displace relative to the hollow 19 in which it resides and in some forms, between '+Theta/2' to '-Theta/2' degrees and in a particular form, between + 1/2 deg and - 1/2 deg. The relative rotation is defined by an axis that is substantially orthogonal to the sides of the infilling portion - this enabling the frame members participating in a respective joint to angularly displace relatively in a substantially planar manner but to otherwise be restrained against any relative displacement other than that associated with the lengthening of one or more frame members. In some forms, referencing Fig 9, 16 each leg 41, 42 comprises a substantially rectangular member having a depth substantially the same as the depth d3 of the hollow 19 in which it resides and a basic width w3 less than the width w1 of the respective hollow so as to be able to angularly displace relative to the hollow 19. Part-way along each leg 41, 42 there are opposed, identical protruding wings 44 designed to abut the internal walls of the inner and outer edge walls 21, 22 that are separated by distance w1; the wings 44 having outermost portions that are separated by a distance W4 that in some forms exceeds the width w1 to require the wings 44 to be displaced towards each other (under load) when being inserted into the respective hollow 19. During adjustment of the wing 1 each frame member 11 would relatively rotate about the or each respective finger 44. In some forms, each wings 44 is configured as an elastically deformable extensions to the respective legs 41, 42. The incremental distance W4 less w1 is the distance the wings need to be displaced

17864239_1 (GHMatters) P107305.AU.2 towards each other (under load) when being inserted into the respective hollow 19 - this distance being configured to accommodate tolerances in the extrusions and to urge the respective leg 41, 42 to towards a substantially centrally located position between the inner and outer edge walls 21, 22. In some forms, the hub 144 include cavities 46 configured to retain the heads 47 (with minimal working clearance) of the operable members 48 that in some forms comprises a screw or bolt; in substantially rectangular wings, a first operable member 210 extends into a first frame member 12 and a second operable member 211 that extends into a second frame member 13. Each operable member 48 includes a shank 49 that extends to protrude from the respective leg 41, 42 to engage with a respective corner block 52 retained within the hollow 19 of the respective frame member 12, 13. The corner block is retained by means that may include a edge screw 50 that extends orthogonally to engage in an edge hole 51 in the corner block 52 after passing through an aperture 53 in the respective outer edge wall 21. Preferably each corner of the wing is constructed thus. In some forms, in the smallest configuration, referencing Fig 12, the legs 41 and 42 are fully inserted into the hollows 19 of the respective first and second frame members 12, 13 to abut the respective corner block 52. As stated above, the wing has its shape/size changed by rotating one or more operable members 48 to displace one or more corner blocks 52 away or towards their respective hub 144 to change their respective "effective lengths" and in response included angles may correspondingly be changed. In the cornerjoint represented in Fig 13, we can see that the corner block 52 and frame member 12 have together been displaced Delta L relative to the hub 144 (to increases its effective length by Delta L) and the end of frame member 13 has correspondingly been outwardly displaced by Delta L. SLIDE MECHANISMS In some wings, each frame member 11 is operatively connected to the adjacent infill edging 150 by slide means 70 that restrains the respective frame member 11 against longitudinal displacement relative to the adjacent infill-edging 150 that it overlaps. In some forms of wings, there is at least one slide mechanism 70 located relative to each end of each frame member 11 and there are preferably slide means 70 spaced along the length of each frame member 11. In some forms, each slide means 70 includes at least one elongated stud 71 that extends from an aperture 72 in the side of a corresponding infill-edging member 25, 26 (to which it is attached) to extend through an aperture 79 in the infilling portion to extend freely

17864239_1 (GHMatters) P107305.AU.2 through the adjacent laterally elongated orthogonal slotted aperture 73 in the exterior side wall 15 of the frame member in which it resides. Each stud 71 is able to slide freely within the elongated orthogonal slotted aperture 73 but is unable to displace relatively in a longitudinal direction. The slotted aperture 73 is defined in part by an axis that is substantially at right angles to the axis of the frame member in which it resides and it has a width substantially the same as the diameter of the stud 71 and has a length sufficiently long to enable relative orthogonal displacement between the infill-edging and frame member within pre-determined limits. A FIRST WING CONFIGURATION By way of example only, consider a wing configured to have a substantially rectangular infilling portion 8 supported by an infill-edging 150 comprising two pair of opposed infill-edging members 25-25, 26-26 supported within the channels 6 of two pair of opposed outer frame members 12-12, 13-13 connected by adaptable corner joints 40 that each include an operable fastener 48 and where the infill-edging members 25, 26 are connected at multiple points along their respective lengths to the adjacent outer frame member 12, 13 by slide means 70 each including a stud 71. Relative to a smallest configuration, operation of an operable fastener 48 causes an outer frame member 12, 13 to have a longer (changed) length and an adjacent outer frame member 13, 12 to displace outwardly away from the infilling portion 8 while the infilling portion 8 remains substantially undisplaced relative to the other outer frame members 12, 13 because relative longitudinal displacement between the infilling portion 8 and frame members 12, 13 is precluded by the slide means 70 described above. Other operable members may similarly be operated till the desired shape is obtained for the outer wing. This form of wing would best be adjusted by displacing each opposed frame member an equal distance from the infill. SPRING MECHANISM The frame 3 and infill-edging 150 in some forms of wing, are operably connected by at least one spring mechanisms 130 referencing Fig 8, 12, 15 and preferably each frame member 12, 13 is so interconnected to the infill-edging 150 at multiple places along their respective lengths with a view to ensuring the infilling portion remains well tensioned. By way of example only, consider a wing 1 referencing Fig 2, having a substantially rectangular inextensible but bendable infilling portion 8, the side-channel 16 of each first frame member 12 being occupied by a corresponding first infill-edging member 25 and at least one spring mechanisms 130 that acts to urge the first infill-edging member 25 outwardly, the side-channel 16 of each first second member 13 being occupied by a

17864239_1 (GHMatters) P107305.AU.2 corresponding second infill-edging member 26 and at least one spring mechanisms 130 that acts to urge the second infill-edging member 26 outwardly. When a frame member 11 has its length increased and the adjacent outer frame member 11 is displaced away from the infilling portion 8 the springs 130 adapt to accommodate the relative displacement while ensuring the infilling edging members 25, 26 remain subject to outwardly directed forces that ensure the infilling portion remains well tensioned. Some forms of spring mechanism 130 comprise a double torsion spring 130 having first torsion spring 132 connected to a second torsion spring 133 by a bridge portion 131 each torsion spring in application abutting and exerting an outwardly directed force on the internal side of the outer edge wall 21 (defining in-part the hollow 19) of the supporting frame member 11 within which it resides; the first torsion spring 132 having a first arm 134 and the second torsion spring 133 having a second arm 135 each arm in application abutting and exerting an inwardly directed force on the internal wall of the inner edge wall 22 of the supporting frame member; the bridge portion 131 abuts the adjacent spring stud 185 connected to the infill edging 150 while extending into the hollow 19, and in any case, the stud 185 is located between the internal wall of the outer edge wall 21 and the bridge portion 131. The spring stud 185 has free displacement within a slotted aperture 186 in the exterior side wall 15 similarly as does stud 71 in slotted aperture 73 and in some configurations, the spring shares stud 71 so that in effect stud 185 comprises stud 71 and the slotted aperture 186 comprises slotted aperture 73. During adjustment of the wing and where the outer edge wall 21 is displaced away from the infill 2, the bridge 131 is urged to displace away from the infill 2 but it cannot because it restrained by the stud 185, 71. Instead the spring 130 is caused to flatten and the arms 134, 135 to spread to exert an increased force on the internal wall of the inner edge wall 22 whereby to provide increased resistance to the outwards displacement of the supporting frame member 11 while providing an increased force on the infill-edging 150 via the stud 185, 71. During adjustment of the wing the outwardly urged studs 185, 71 are able to slide freely in their respective orthogonal slotted apertures 186, 73 in response to one or more frame members being urged to displace away from or towards the infill-edging 150. The spring mechanisms are able to automatically adjust to maintain outwardly directed forces on the infill-edging 150 with a view to ensuring the infilling portion 8 remains well tensioned at all times. Spring mechanisms 130 are preferably employed at multiple points along the infill edging 150 and for convenience, wherever a slide mechanism is employed, in which case,

17864239_1 (GHMatters) P107305.AU.2 the stud 185 takes the form of stud 71 and the slotted aperture 186 takes the form taking the form of slotted aperture 73. This arrangement has particular relevance when the infill-edging members 25, 26 are flexible as described above. Where the infilling portion comprises glass or the like, spring mechanisms may electively be employed at multiple places along their respective lengths with a view to minimizing any free movement between components or rattling of the wing that may result from manufacturing tolerances such as the width of the elongated slotted apertures. A SECOND WING CONFIGURATION By way of example only, consider the wing described under the heading, "A First Wing Configuration" but where the wing 1 is further configured such that each first infill edging member 25 is connected to the adjacent first outer frame members 12 by slide means 70 that each include a stud 71 acted on by a spring 130 and where the springs on opposite sides of the wing are equally depressed to exert equal and opposite forces on the infill, and each second infill-edging member 26 is connected to the adjacent second outer frame members 13 by adapted slide means 75 that each include a stud 71 acted on by a spring 130, but where the adapted slide means 75 is characterized by enlarged (widened) orthogonal slotted apertures 186 that enable limited relative longitudinal displacement between the studs 71 and frame members 13. Relative to a smallest configuration, operation of a second operable fastener 211 causes the corresponding second frame member 13 to become longer and the adjacent first frame member 12 to displace outwardly away from the infilling portion, this action causing one or more springs 130 within the displaced first outer frame member 12 to further compress and exert a greater force along the infill-edging member 25 to urge the infill edging 150 laterally towards the displaced first outer frame member 12. In response to this, the infilling portion 8 displaces till the forces acting on both sides of the infill are substantially equal and correspondingly, the infill is substantially centralized. This lateral displacement of the infill is enabled by the enlarged (widened) orthogonal slotted apertures of the slide means associated with the second frame members. Some forms of door include this "second wing configuration" where the vertical door frame members are configured as a first frame members and the upper and lower door frame members are configured as second frame members. A benefit of this configuration is that during adjustment to change the shape of the door (that sometimes would be performed by unskilled people) the infill automatically adjusts to assume a substantially central position between the vertical frame members. THREADED INTERCONNECTING MEANS

17864239_1 (GHMatters) P107305.AU.2

In some forms, referencing Fig 8, 9, 10 at least one stud 185, 71 (and in some configurations all studs 185, 71) includes a threaded aperture 76 located coaxially with an aperture 77 in the outer edge wall 21, 30 of the frame member 11 where in some forms aperture 77 is configured as an aperture within a Rivnut 178 that extends between the first and second frame member 23, 24 and where the Rivnut 178 extends through coaxial apertures 179 in the first and second frame member 23, 24 to connect them together. Where aperture 76 is engaged by a fixing fastener 80 it is required to be threaded and where a stud-guide 78 extends through aperture 76 it may be unthreaded but alternatively the stud-guide 78 may have a threaded shank 84 that is sufficiently small in diameter to not engage with the threaded aperture 76. In some forms, the stud-guide 78 has a short threaded portion able to engage with the aperture 77 to be retain relative to the frame. The fixing fastener 80 has a threaded shank 85 that engages with the threaded aperture 76 and in some forms, a short portion of the shank lies within the mouth of the Rivnut to help retain the fixing fastener 80 relative to the frame. In some forms, the fixing fastener 80 comprise grub screws and in some forms comprises a zinc plated grub screw having a drive recess located within the mouth of the Rivnut to be accessible by a tool that may comprise an Alan key 212. We can also consider the stud 71, 185 to be restrained against sideways relative displacement by the stack-up of component thicknesses wherein a stud-guide 78 or fixing fastener 80 (described below) is held spaced from the exterior side wall 15 by the interspaced bridge 131 of spring 130; the bridge 131 being defined by an axis substantially orthogonal to that of the slotted aperture 73 and unable to be displaced into the slotted aperture 73. The fixing fastener 80 is operable to apply an outwardly directed force on the stud 71 and infill-edging and/or to outwardly displace the associated stud 71. These fixing fastener 80 are particularly relevant to wings suspended adjacent to openings in concrete walls defined by steel frame members that have been forced to bow inwards - in this case, fasteners 80 on each side of the wing can be tightened to draw the frame members 12 inwardly to better suit the opening. In some forms each stud 71, 185 extends to protrude from the infill-edging 150 on the exterior side to abut (or be in close proximity to) the side-fin 17 and extends inwardly to abut (or be in close proximity to) the inner frame wall 14. In a particular form, the Rivnut has a M8 internal thread that the fixing fastener 80 (configured as a M6 grub screw) can pass freely through to engage aperture 76 having an internally threaded aperture M6; and stud-guide 78 is configured to have a 4.5 Dia. shank

17864239_1 (GHMatters) P107305.AU.2 and a head configured as portion of an M8 grub screws that can engage the internal Rivnut; this configuration of fasteners enabling them to be interchangeable at any time. GALVANIC CORROSION In some forms, referencing Fig 16, the woven mesh 120 comprises 304 or 316 stainless steel as does the infill-edging members 25, 26 as does stud 71. In some forms, an insulating strip 110 (that may comprise adhesive backed nylon strip) is attached to the interior side of the infill 2 and to the exterior side of side-channel 16 to avoid contact between these members and the walls of the side-channel 16. In some forms, the stud is separated from the slotted aperture 73 by an insulating sleeve that extends along the shank of the stud 71 and in some forms the bridge 131 of the spring is enveloped by an insulation sleeve. In some forms, referencing Fig 9, the lip 174 of the frame 11 is enveloped by an peripherally elongated insulating member 175 to keep the infilling portion 8 separated from the frame 11. LOCKS, HINGES & ROLLERS In some wings configured as Conventional Australian Security Doors, referencing Fig 14, the closing edge 213 is adapted to support a lock body 95 of a lock 90 that in some forms comprises an Australian Security Door Lock 92. The outer edge 21, 30 and the overlying side-fin return 173 include an aperture 93 to receive the lock body 95 and the frame is also adapted to include opposed apertures 96 in the interior 14 and exterior 15 side walls and side-fin 17 to enable all the communicating lock components 91 to extend sideways to mesh with apertures in the lock body 95; there being an aperture in the lock body corresponding to a cylinder 94, aperture corresponding a drive rod 97, apertures corresponding handle back plate fixing spigots 98; this being common and well understood in the trade. Apertures 96 are overlaid by handle back plates mounted on both sides of the door adjacent to the lock body - their footprint 99 covering the apertures 96 as is well known. Where the wing is configured as a hinged door, the first frame member 12 (opposed to the closing edge 213) is adapted to be connected to hinges 100 and that may comprise making spaced apertures to enable hinge fixing screws to be attached. The closing edge outer edge wall 21, 30 is prepared for the lock by well known means that may include displacing a cutting tool through the outer edge wall between the side-fins 18 to remove a rectangular portion of the wall of the channel 58 whereby to create a rectangular aperture 93. The side apertures 96 are manufactured by placing a mandrel (having within it, an aperture 116 substantially the same as aperture 96) through aperture 93 and by

17864239_1 (GHMatters) P107305.AU.2 displacing a cutting tool (having a shape substantially the same as aperture 96) through the of the walls 14, 15 respectively and into the aperture of the mandrel whereby to displace a portions of the walls 14, 15 - as is well understood and common in door manufacture. CORNER COVERS As stated above, the wing has its shape/size changed by rotating one or more operable members 48 to displace one or more corner blocks 52 and frame members 12, 13 away or towards their respective hub 144 to change the "effective length" of the respective frame member. In doing so, portions of respective hubs 144 becomes visible. To address this issue referencing Fig 17 to 19, an exterior cover 55 and an interior cover 56 are attached to opposite sides of each corner, each having a first portion that extends along the first frame member 12 to cover the cut end 187 in all configurations of the wing and having a second portion that extends along the second frame member 13 to cover the cut end 188 in all configurations of the wing. Each cover has a pair of spaced inwardly projecting substantially cylindrical bosses 192, 193 respectively each extending to abut an opposed corner 189 of the recess 147 in the hub 144 to retain the covers against rotation relative to the connector 45. Each exterior boss 192 includes an elongated threaded recess 194 that extends from below the surface to in application be invisible and each interior boss 193 includes an elongated recess 195 that extends from the surface to in application be accessible to enable the insertion of a screw or other fixing fastener and to have a diameter providing free passage to the fastener. Each portion of the exterior cover includes a first exterior return 196 that extends along the channel 58 and sideways to the centre of channel 58. The finl8 adjacent the first return 196 is removed and the return 196 has a thickness the same as channel 58 so in application, the return does not protrude beyond the line of the fin 18. Each portion of each interior cover 56 includes a first return interior 197 that extends along the channel 58 and sideways to the centre of channel 58. The finl8 adjacent the first interior return 197 is removed and the return 197 has a thickness the same as channel 58 so in application, the return does not protrude beyond the line of the fin 18. The first returns 196 and 197 of course abut along the centre line of channel 58. Each portion of the exterior cover 55 also includes a second exterior return 198 attached to the first return 196 and that extends alongside the adjacent finl8 without extending into the channel 58 and without the need to remove the adjacent fin 18 portion. Each portion of each interior cover 56 includes a second interior return 199 that extends along the channel 58 and sideways to abut the spaced (exterior) fin18. The fin18 adjacent the second interior return 199 is removed and the return 199 has a thickness the

17864239_1 (GHMatters) P107305.AU.2 same as channel 58 so in application, the return 199 does not protrude beyond the line of the fin 18. The second returns 198 and 199 each a have a longitudinal length that exceeds the maximum distance the respective frame member will be displaced away from the hub 144 so at all times the exterior side fin 18 will extend from a slotted recess 200 so that no portion of the cut fins 18 is visible from the exterior side 181 of the wing. Where the first returns abut the faces are interrupted to provide apertures 219 coaxial with apertures 218 for passage of an Alan key into the drive recess of the operable members 80. RESISTANCE TO ATTACK Doors are subject to two common forms of attack: a) Pulling the bottom corner on the lock side (closing edge) outwardly (in the hope of making a gap large enough for entry), this action having the affect of stretching the interior side wall 14 of the closing edge frame member 12 and compressing and buckling the exterior side 15 and side-fin 17. The two-part frame described within comprising a second frame member 23 attached to a first frame member 23 has a moments of inertia in excess of that for a typical security door frame and is more resistant to deformation and in particular, to buckling of the outer frame wall 25 which happens in the most common form of failure. b) A jimmy is placed between the door (adjacent to the lock) and the opening frame and worked in an attempt to force the lock and adjacent frame member 12 away from the door opening frame 154 to disengage the lock bolt from a strike plate attached to the opening frame as is well known Again, the two-part frame described within comprising a second frame member 23 attached to a first frame member 23 has moments of inertia in excess of that for a typical security door frame and is more resistant to deflection. Resistance to such deflection can be further increased by attaching a piece of steel tube 180 within the hollow 19 rearward of the lock to extend upwardly and downwardly from the lock to at least compensate for the reduction in frame strength caused by apertures 93 and 96 SECOND EMBODIMENT INFILLING PORTION As stated above, in the second embodiment, each frame member comprises an elongated hollow thin-walled member having a substantially rectangular cross-section defined in-part by an exterior side wall B15 and a wider interior side wall B14 that also forms a wall of the elongated side-channel B16 that extends laterally beyond the exterior wall B21.

17864239_1 (GHMatters) P107305.AU.2

In some forms the frame members 12B, 13B are relatively positioned such that the respective side channels 6B together form a substantially continuous uninterrupted side channel16B. In some forms, the infilling portion B8 is comprised of material that is substantially inextensible and therefore resistant to stretching. In some forms, it is substantially planar, inextensible but bendable but when supported as described below, it is resistant to bending and substantially resistant to shearing within the plane that substantially defines it. In some such forms it comprises perforated sheet metal B121 or woven steel mesh B120 that in some forms comprises woven 304 S/S or 316 S/S wire and in some forms, having a diameter between 0.7 and 0.9 MM. In some forms the infilling portion 8 would be manufactured by processes including cutting to size, slitting and laser cutting. As stated above, experience has shown that unless an infilling portion B8 (that is inextensible but bendable) is well supported along its peripheral edge B20 and held tensioned it may become "loose and floppy" and able to displace sideways in response to displacement of the wing, attack or even wind and outwardly directed forces acting along the infill-edging B150 act to oppose this inwards displacement and hence they act against skewing; in some forms fixing fasteners B80 act to actually prevent the infill-edging members B25-B25 and B26-B26 from displacing relative to the frame 3 and hence towards each other. In some wings, the infilling-edging B150 is acted upon by outwardly directed forces that "well tension" the infilling portion B8 whereby to preclude sideways displacement of any part of the infilling portion B8 in excess of a pre-determined limit and to preclude skewing by forces up to a pre-determined limit. These outwardly directed forces in some wings derive from one or more types of interconnecting means that include springs B130 and/or fixing fasteners B80. Importantly, the interconnecting means accommodate relative displacement of the frame members to allow the frame to change shape as described below. Where the infilling portion B8 comprises glass or the like, the infilling portion is unable to substantially skew and where spring mechanisms are employed, they act to urge the infilling portion against lateral displacement relative to the frame and in some wing configurations, they act to centralize the infilling portion 8 between opposed frame members INFILL-EDGING CONSTRUCTION In some forms of wing B1, the peripheral edge B20 is adapted to participate in an infill-edging B150 that in some forms also includes infill-edging members B25, B26 and preferably the channel B16 has a depth which provides minimal working clearance to

17864239_1 (GHMatters) P107305.AU.2 provide good support for the infilling edging B150 to restrain it against axial rotation and sideways deflection while not restricting lateral displacement relative to the frame. In other forms, the infill-edging members B25, B26 referencing Fig 23, each comprise a separate elongated members while in other forms again, the infill-edging members B25, B26, each comprise multiple discrete relatively short members. In some forms, the infilling portion B8 is bendable and able to be bent and in some such forms, referencing Fig 21 and 26, the peripheral edge B20 is configured to extend across the exterior side B28 of a respective infill-edging member B25, B26 to be folded at a first corner to extend along the outer edge B29, to be folded again to extend along the interior side B31 to form a U-shaped return B7; this folding providing greatly enhanced retention of the peripheral edge B20 because of the torturous path the peripheral edge B20 would need to slide over and deform over to separate from the respective infill-edging members B25, B26; this folding around the infill-edging members B25, B26 for ease of description being referred to herein as "wrapping around". Preferably at least spaced portions and some forms, substantially the entire peripheral edge B20 is adapted to include a peripherally elongated U-shaped return B7 that participates in an infill-edging B150 that includes elongated infill-edging members B26, B25 that extend relative to at least the majority of the peripheral edge B20. In some forms, prior to assembly, the infilling portion B8 is intermittently slit along lines corresponding to the bends and folds described above to enable the infilling portion 8 to be more easily/neatly folded Where the infill B2 is substantially rectangular the infill-edging members B25-B25, B26-B26 comprise substantially parallel spaced first infill-edging members B25 and substantially parallel spaced second infill-edging members B26, where the second and first infill-edging members B25, B26 are substantially orthogonally positioned. In some forms, referencing Fig 21, 22, 26, the infill-edging members B25, B26 comprise longitudinally elongated (straight) bars or strips B10 (having exterior surfaces defined by a common plane) and in some forms they comprise 304 or 316 stainless steel having well known properties that include the ability to elastically deflect under load. In a specific form of the first embodiment, the infill-edging members have a rectangular cross section that is 3 MM thick and 16 MM Wide. In a particular form, the depth of the side-channel B16 is required to not exceed 8 MM and because the fixing screw B80 is required to be not less than M4 for strength reasons, and because the infilling portion in some forms is 1.8 MM thick, the depth of the infill-edging member B26 referencing Fig 26, needs to be expanded locally to provide for the

17864239_1 (GHMatters) P107305.AU.2 recess or aperture B88 and B89 that extends inwardly from the edge of the infill-edging member B25, B26. In some such forms this is provided by longitudinally slitting the infill edging member B26, B25 locally to form strips B87 and then outwardly forming adjacent strips B87 in opposite directions as shown in Fig 26 to form an enlarged knuckle B86 (and later if necessary drilling the required aperture to size and tapping a thread where necessary) - adjacently to the knuckle B86, the infilling portion B8 is removed to observe the 8 MM limitation. In some simplified forms of the first embodiment, each first frame members B12 and each second frame member B13 are replaced by an alternative first frame member B62 and an alternative second frame member B63 each configured to have an alternative profiled channel B61 that includes ratchet shaped teeth B64 and adhesive B65 substantially as described in Australian patent AU2008 202835. The respective peripheral edges B20 of the infilling portion B8 extend into respective channels B61 to be attached there as described in Australian patent AU2008 202835 herein included by reference and as described in the Abstract, reproduced herein as Fig 32 and the infill edging members B25, B66 and BB6, B67 would be omitted. In this cases, the frame members B62, B63 would be displaced (as described elsewhere to change the shape of the wing) after which the peripheral edge B20 would be fixed to the adjacent frame members B12, B13. However the method described in AU2008 202835 is adapted such that the protective plastic strip commonly used to separate the adhesive strips from the infilling portion is left in place till the alternative frame has been adjusted to attain the desired shape then protective strips would be peeled off, and the wedge B217 referencing Fig 27 would be driven in. In some cases, the alternative frame would be marginally increased is size after the peripheral edge had been fixed to the frame to well tension the infilling portion. In some forms where the infill-edging members B26, B25 are flexible and have elasticity properties and are able to deflect within their respective lengths and where it is desirable they be maintained in a substantially straight (rectilinear) form, they are preferably supported at multiple points within their respective lengths by interconnecting means to maintain any deflection within acceptable predetermined limits. In some forms the infilling portion B8 includes material that is rigid (as described in the first embodiment) and substantially resistant to deflection and unable to be bent or skewed and in some such forms it comprises glass sheet. In some such forms it is supported along its peripheral edge B20 by means including extending into a channel of alternative infill-edging members (as described above) and in some forms to be retained there by

17864239_1 (GHMatters) P107305.AU.2 means including adhesive (as described in the first embodiment); in some forms there are enlarged apertures in the glass to accommodate threaded inserts that are able to engage with studs . In other forms the infilling portion includes other suitable substantially inextensible material. FRAME In some forms referencing Fig 21, 22, 24, the frame B3 comprises elongated hollow frame members B11 that extend relative to (to help define) the respective edges B183 of the wing. In some forms, each frame member B11 has a substantially rectangular cross-section including a substantially rectangular hollow B19, an outer edge wall B21 connected to an opposed inner edge wall B22 by an exterior side wall B15 and an interior side wall B14

. Sidewall B14 and wall B17 are outwardly extended to form a pair of fins B18 that protrude relative to outer edge wall B21 to define between them the edge channel 58 Each frame member B11 is adapted to include a longitudinally elongated outer channel-wall B17 that extends laterally to help form the substantially U shaped side-channel B6 that extends between the interior side wall B14 and the outer channel-wall B17; the outer channel-wall B17 extending along the length of each frame member while extending laterally towards the inner edge wall B22; the side-channel 6 defined in part by an lateral opening B140 and a channel end wall 174. In the smallest configuration of the wing, the infill-edging members B25, B26 lie in close proximity to the closed end B5 of the side-channel B16. The wing also has a largest configuration where the peripheral edge B20 and/or the infill-edgingB150 and/or infill-edging members B26, B25 as the case may be, are displaced from the closed end B5 of the side channel B16 and in some such forms, the infill-edging members B25, B26 are parallel to their respective orientations in the smallest configuration. In a particular form, the infill referencing Fig 23, is substantially rectangular and the frame B3 is substantially rectangular and comprises spaced substantially parallel first frame members B12 (that in some wings are substantially vertical) and substantially parallel spaced second frame members B13 (that in some wings are substantially horizontal), each first frame member B12 being connected at each end to a respective second frame member B13 by a respective corner joint B40 referencing Fig 23; in some such forms the side channel B16 of each first frame member B12 being occupied by a corresponding first infill edging member B25, the side-channel 6 of each second frame member B13 being occupied by a corresponding second infill-edging member 26. CORNER JOINTS

17864239_1 (GHMatters) P107305.AU.2

In some forms, referencing Fig 24, 25, 28, 29, the frame member are connected by adaptable corner joints B40, where each of a pair of frame members participating in a respective joint are connected to each other by a corner connector B43 comprising angularly spaced legs B41, B42; a second leg B42 extending within the hollow B19 of a second frame member B13 and a first leg B41 extending within the hollow B19 of a first frame member B12. In some forms, the frame members participating in a respective joint are connected to a hub B144 from which a pair of operable members B48 extend, each to engage a respective corner block B52 fixed relative to a respective frame member B11, each said operable member B48 operable to displace the respective corner block B52 and respective frame member B11 away from the hub B144 whereby to change the effective length of the respective frame member whereby to change the shape of the wing. In some forms referencing Fig 24, 25 each cornerjoints B40 is angularly adaptable and the ends B187 and B188 of the first and second frame members respectively are angled at less than 45 degrees to expose a gap B54 occupied in part by the hub B144. The or each leg B41, B42 is able to angularly displace relative to the hollow B19 in which it resides and in some forms, between '+Theta/2'to '-Theta/2' degrees and in a particular form, between

+ 1/2 deg and - 1/2 deg. The relative rotation is defined by an axis that is substantially orthogonal to the sides of the infilling portion B8 - this enabling the frame members B11 participating in a respective joint to angularly displace relatively in a substantially planar manner but to otherwise be restrained against any relative displacement other than that associated with the lengthening of one or more frame members. In some forms, referencing Fig 24, each leg B41, B42 comprises a substantially rectangular member having a depth substantially the same as the of the hollow B19 in which it resides and a basic width w3 less than the width w1 of the respective hollow so as to be able to angularly displace relative to the hollow B19. Part-way along each leg B41, B42 there are opposed, identical protruding side protrusions B44 designed to abut the internal walls of the inner and outer edge walls B21, B22 that are separated by distance w1; the wings B44 having outermost portions that are separated by a distance substantially w1. During adjustment of the wing 1, each frame member B12, B13, would relatively rotate about the or each respective finger B44. In some forms, each wings B44 is configured as an elastically deformable extensions to the respective legs B41, B42 and in some forms they are substantially as described in Embodiment 1. Some cornerjoints include a hub B144 comprising a substantially right-angled plates that include apertures B145 coaxial with a first operable member B210 that extends into a

17864239_1 (GHMatters) P107305.AU.2 first frame member B12 and a second operable member B211 that extends into a second frame member B13, each passing through a respective aperture B145 to be retained by a circlip B146 situated in a groove in the shank B 49 of the operable member adjacently positioned to the underside of the apertures B145. Each operable member B48 includes a shank B49 that extends to engage a respective corner block B52 retained within the hollow B19 of the respective frame member B12, B13 - in some forms it comprising a small substantially rectangular block having a head that resides in channel B58 and a portion that extends through an aperture B53 in the outer wall B21 to protrudes in hollow B19 and including a longitudinally elongated threaded aperture coaxial with the associated operable member. As stated above, the wing has its shape/size changed by rotating one or more operable members B48 to displace one or more corner blocks B52 towards or away from the hub B144 to change their respective "effective lengths" and in response included angles may correspondingly be changed. SLIDE MECHANISMS & FIXING FASTENERS In some wings, referencing Fig 22, 25, 26, 28, each frame member B11 is operatively connected to the adjacent infill-edging B150 by slide means B70 that restrains the respective frame member B11 against longitudinal displacement relative to the adjacent infill-edging B150 that it overlaps. In some forms of wings, there is at least one slide mechanism B70 located relative to each end of each frame member B25, B26 and there are preferably slide means B70 spaced along the length of each frame member B25, B26. In the second embodiment, each slide means B70 comprises a elongated unthreaded guide-stud B78 that extends through an unthreaded aperture B77 in the outer edge wall B21 to be restrained relative to the frame B11 and having a shank that extends freely within an edge recess B88 that extends laterally inwardly from the edge of a respective infill-edging member B25, B26. Some wings include one or more fixing fastener B80 each extending through an aperture B77 in the outer edge wall B21 to be restrained relative to the frame and having a threaded shank that extends to engage in a threaded edge recess B89 that extends laterally inwardly from the edge of a respective infill-edging member B25, B26. A FIRST WING CONFIGURATION By way of example only, referencing Fig 23 consider a wing configured to have a substantially rectangular infilling portion B8 supported by an infill-edging B150 comprising two pair of opposed infill-edging members B25-B25, B26-B26 supported within the channels B6 of two pair of opposed outer frame members B12-B12, B13-B13 connected by angularly adaptable corner joints B40 that each include an operable fastener B48 and where the infill

17864239_1 (GHMatters) P107305.AU.2 edging members B25, B26 are connected at multiple points along their respective lengths to the adjacent outer frame member B12, B13 by slide means B70 each including a guide-pin B78 Relative to a smallest configuration, operation of an operable fastener B48 causes an outer frame member B12, B13 to have a longer (changed) length and an adjacent outer frame member B13, B12 to displace outwardly away from the infilling portion B8 while the infilling portion B8 remains undisplaced relative to the other outer frame members B12, B13 because relative longitudinal displacement is precluded by the slide means B70 described above. Other operable fasteners B48 may similarly be operated till the desired shape is obtained for the outer wing. This form of wing would best be adjusted by displacing each opposed frame member B12, B13 an equal distance from the infill. SPRING MECHANISM The frame B3 and infill-edging B150 in some forms of wing, are operably connected by at least one spring mechanisms B130 referencing Fig 21, 25 and preferably each frame member B12, B13 is so interconnected to the infill-edging B150 at multiple places along their respective lengths with a view to ensuring the infilling portion remains well tensioned. Some forms of spring mechanism B130 comprises a torsion spring B130 that resides in the side-channel B16 having a first arm B134 held against displacement by abutting the channel end wall B174 and a second arm B135 held against displacement by abutting the edge of an infill-edging member B25, B26 to urge that infill-edging member outwardly During adjustment of the wing and where the frame member B11 (and outer edge wall B21 and channel end wall B174) are displaced away from the infill B2, the spring 130 is caused to flatten and the arms B134, B135 to spread to exert an increased force on the channel end wall B174 to provide increased resistance to the outwards displacement of the supporting frame member B11 while providing an increased force on the infill-edging B150. Each spring mechanism is able to automatically adjust to maintain outwardly directed forces on the infill-edging B150 with a view to ensuring the infilling portion B8 is well tensioned at all times. Spring mechanisms B130 are preferably employed at multiple points along the infill-edging B150. This arrangement has particular relevance when the infill edging members B25, B26 are flexible as described above. A SECOND WING CONFIGURATION By way of example only, consider the wing described under the heading, "A First Wing Configuration" but where the wing B1 is further configured such that each first infill edging member B25 is connected to the adjacent first outer frame members B12 by slide means B70 and is acted on by a spring B130 and where the springs on opposite sides of

17864239_1 (GHMatters) P107305.AU.2 the wing are equally depressed to exert equal and opposite forces on the infill, and each second infill-edging member B26 is connected to the adjacent second outer frame members 13 by adapted slide means B75 and by a spring 130, but where the adapted slide means 75 is characterized by widened apertures B88 that enables limited relative longitudinal displacement between the pin-guides B78 and frame members B13. Relative to a smallest configuration, operation of a second operable fastener B211 causes the corresponding second frame member B13 to become longer and the adjacent first frame member B12 to displace outwardly away from the infilling portion, this action causing one or more springs B130 within the displaced first outer frame member B12 to further compress and exert a greater force along the infill-edging member B25 to urge the infill-edging B150 towards the displaced first outer frame member B12. In response to this, the infilling portion B8 laterally displaces till the forces acting on both sides of the infill are substantially equal and correspondingly, the infill is substantially centralized. The lateral displacement of the infill is enabled by the enlarged (widened) apertures B88 of the slide means associated with the second frame members. Some forms of wings include this "second wing configuration" where the vertical frame members are configured as a first frame members and the upper and lower door frame members are configured as second frame members. A benefit of this configuration is that during adjustment to change the shape of the wing (that sometimes would be performed by unskilled people) the infill automatically adjusts to assume a substantially central position between the vertical frame members. GALVANIC CORROSION In some forms, referencing Fig 21, the woven mesh B120 comprises 304 or 316 stainless steel as does the infill-edging members B25, B26. In some forms, an insulating strip B110 (that may comprise adhesive backed nylon strip) is attached to the interior side of the return portion of the infill-edging member and to the exterior side of side-channel B16 to avoid contact between these members and the walls of the side-channel 16. CORNER COVERS As stated above, the wing has its shape/size changed by rotating one or more operable members B48 to displace one or more hubs B144 away or towards their respective corner blocks B52 to change the "effective length" of the respective frame member. In doing so, portions of respective hubs B144 becomes visible. To address this issue corner covers substantially as described for the first embodiment are attached to the sides of the wing adjacent to each corner, an exterior cover B55 and an interior cover B56 that are connected together by ultrasonic welding or other well known means, each having a first portion that

17864239_1 (GHMatters) P107305.AU.2 extends along the first frame member B12 to cover the cut end B187 in all configurations of the wing and having a second portion that extends along the second frame member B13 to cover the cut end B188 in all configurations of the wing. Each portion of the exterior cover includes a first exterior return B196 that extends along the channel B58 and sideways to the centre of channel B58. The fin B18 adjacent the first return B196 is removed and the return B196 has a thickness the same as channel B58 so in application, the return does not protrude beyond the line of the fin B18. Each portion of each interior cover B56 includes a first return interior B197 that extends along the channel B58 and sideways to the centre of channel B58. The fin B18 adjacent the first interior return B197 is removed and the return B197 has a thickness the same as channel B58 so in application, the return does not protrude beyond the line of the fin B18. The first returns B196 and B197 of course abut along the centre line of channel B58. Each portion of the exterior cover B55 also includes a second exterior return B198 attached to the first return B196 and that extends alongside the adjacent fin B18 without extending into the channel B58 and without the need to remove the adjacent fin 18 portion. Each portion of each interior cover B56 includes a second interior return B199 that extends along the channel B58 and sideways to abut the spaced (exterior) fin B18. The fin B18 adjacent the second interior return B199 is removed and the return B199 has a thickness the same as channel B58 so in application, the return B199 does not protrude beyond the line of the fin B18. The second returns B198 and B199 each a have a longitudinal length that exceeds the maximum distance the respective frame member will be displaced away from the hub B144 so at all times the exterior side fin B18 will extend from a slotted recess B200 so that no portion of the cut fins B18 is visible from the exterior side B181 of the wing. Where the first returns abut the faces are interrupted to provide apertures B219 coaxial with apertures B145 for passage of an Alan key into the drive recess of the operable members B80. A PARTICULAR FIRST EMBODIMENT By way of example only, consider a wing configured as a substantially conventional door where the infilling portion 8 comprises inextensible material comprising woven steel mesh 120 and where the height of the wing "H is variable between 2000 and 2050 (50 MM adjustability) and the width "V is variable between 800 and 850 (50 MM adjustability) respectively and so Delta L would be 25 (since 2 x 25 = 50). This configuration clearly embraces the range of sizes common for Australian screen doors where the width is generally between 806 and 818 MM and the height is generally between 2024 and 2042.
