Background and Unresolved Needs

Some of the inventions described within find application in addressing an age-old problem with doors and gates, that of fitting a pre-made door to an opening so as to occupy the opening with acceptable working clearances so as to be neither too large and unable to fit within the opening nor too small and having unacceptable "gaps" around the periphery. Some of the inventions within find application in addressing such a problem that currently exists in relation to security and storm doors screens, windows, window screens, shutters and gates.

Although prompted by the needs outlined above, the inventions within are applicable to structures in general and in particular, to structures that include a frame, and to structures configured as wings that more particularly may take the form of doors, screens, shutters or barriers. This specification describes the integers relating to the various aspects of the inventions described within including the integers relating to the invention claimed within, and it includes integers relating to the invention to be claimed within future divisional applications.

GENERAL

Reverting to the problems wrth doors and screens, some openings are fabricated according to standard dimensions, some are constructed on site of convenient dimensions, some through poor workmanship are non-rectangular and some openings become skewed as a result of house settlement. In spite of this, DlY hardware retailers sell doors of standard sizes to suit such openings often resulting in poorly fitting doors.

In other cases, doors are "made-to-measure" by a time consuming process where the opening is measured and a door is manufactured to suit the particular opening - sometimes even this process results in a poorly fitting door.

The above deficiencies raise the possibility of designing a door that is configurable to suit openings of different widths and/or different heights and raises a particular . objective of some of the inventions within, that of being able to provide a screen door that suits the different common door openings in a particular countries/territory and a more particularly to provide a door that suits all the different common openings.

Such adjustable doors would be manufactured without reference to particular openings (which is time consuming and expensive) and by modern manufacturing techniques and systems resulting in reduced manufacturing costs and improved quality. Further, it would advantageous if (at least some) doors could be configured to fit within a normal sedan vehicle so that they could easily be transported home to be assembled and fitted by the home owner or a handyman - this feature overcoming a difficulty

experienced by shoppers who purchase doors from retail outlets.

In Australia for example, most screen and security doors fall within a range in widths of 806 to 818 MM and within a range of heights of 2024 to 2042 MM so an adjustable door that embraced these ranges could meet would satisfy some of our objective. Doors of course could be configured to embrace other pre-determined ranges to suit common sizes in other jurisdiction or territories.

Notwithstanding that the inventions are described (in some places) with reference to wings including doors, they are not limited to such structures.

In some forms, a structure 1, referencing the figures, includes an infill 2 (that in - some forms is resistant to deformation), the infill in some forms includes laminar glass, woven steel mesh, fiberglass mesh, perforated sheet metal or bars or a combination thereof or any other suitable material and in some forms it includes a peripheral frame that in some forms includes an outer frame 3; the infill 2 and outer frame 3 configured to be relatively disposed and in some forms they are configured to mutually overlap and in some forms including wings, the outer frame 3 supports the infill 2. In some forms, referencing Fig 3, the infill 2 is bounded by a return 4 that extends along the periphery of the infill (and although not limited to, may take the form of a continuous portion or multiple discrete interrupted portions that extend outwardly) to overlap the outer frame 3; some infills are further configured to include a pair of spaced returns 4 configured as sides 5 that define between them, a substantially U shaped, elongated U channel 6 that extends along the periphery of the infill 2 by extending inwardly from an opening 7; in some forms the sides 5 are substantially parallel. In some forms, the infill 2 includes an inner frame 9 that extends along its periphery, this inner frame 9 being configured to include a base 10 from which the return 4 or sides 5 extend outwardly to overlap the outer frame 3 and in some forms, this inner frame 9 extends along the entire periphery of the infill 2.

OUTER FRAME

The outer frame 3 in some forms, extends along the entire periphery of the infill and in some forms, the outer frame is configured to include one or more elongated outer frame members 11 that (although not limited to) in some forms, are hollow and include a longitudinal recess 19, an outer edge wall (or outer edge wall) 22 connected to a side 18 and in some cases, connected to opposed sides 16; (although not limited to, in some forms) having a substantially rectangular cross-section and including a hollow also having a substantially rectangular cross-section where the sides 18 extend between the outer edge wall 22 and the opposed inner edge wall (or inner edge) 21 , referencing Fig 3; the outer frame member 11 defined by an edge depth "D\ a side width "W" and a side-wall thickness T and by a longitudinal axis that in planar wings, is parallel to the plane defining a side of the wing. Some outer frame members additionally include extensions 14 to the sides 18 that form an outwardly disposed peripheral channel 16 that in some forms is WT deep and configured to receive the fixing tabs of a lock, in a particular format it is 3 MM deep.

Hollow rectangular outer frame members are well suited to many structures including structures configured as wings and in particular as doors; they may be manufactured from any suitable material and by any suitable process; in some forms they comprise drawn steel tube, extruded aluminium, roll-formed steel (having the essential features described herein but modified to suit the roll-forming process), extruded plastic (including pvc) and in some forms they are fabricated from multiple portions to have as a . whole, the essential features described herein. In more particular forms, the outer frame is configured to accommodate a lock body and in some forms, it is configured to

accommodate a substantially conventional security door lock body. For convenience and by way of example only, the outer frames employed in the figures are configured to accommodate a substantially conventional Australian security door lock body but the structures described herein are not limited in any way to the examples illustrated.

In some structures, at least one outer frame member 11 has an associated linear joint 23 ["LJ-X" X indicating location in Fig 4] that may be adjusted to change the effective, length of the outer frame member and in some structures, all sides have a corresponding adjustable linear joint 23 that in. some forms is as described in the Patent Specifications included by reference and in some forms, each is as described below. In application, the effective length of one or more outer frame member may be increased in length to render the structure suitable for a larger opening; the objective being to fit? the opening with the structure with only working clearances.

A particular form of structure includes a rigid infill bounded by an inner frame on all sides that is bounded by an outer frame on all sides where the outer frame has a smallest configuration where each outer frame member abuts a corresponding inner frame member 24 along its length, and where each corner has an included angle equal to its respective nominal included angle. In some structures, after the structure has been adjusted to a larger extent the outer frame members are parallel to their respective configurations in the smallest configuration; in which case, each corner joint has an included angle that is equal its respective nominal angle and the joint is referred to as being "perfect" . In some cases, the outer frame members will become not parallel to their respective configurations in the smallest configuration resulting in at least one corner joint having an included angle ["Alpha"] that differs (by a deviation) from its respective nominal angle.

In a particular form of structure configured as a "rectangular structure" the inner frame is substantially rectangular and the outer frame has:

1 ) a smallest configuration where each outer frame member abuts a

corresponding inner frame member 24 along its length, and

2) nominal angles of ninety degrees at each comer, and

3) the outer frame includes an upper outer frame member 31, a lower outer frame member 32, a left hana" side outer frame member 33 and an opposed right hand side outer frame member 34; the upper and lower outer frame members 31 ,32 connected to a left and right hand side outer frame member 33,34 by respective corner joints. In some forms, Each outer frame member includes a pair of outer frame portions connected by a linear joint that may take a form described in the patent speifications included by reference or as described below and in some forms, each outer frame member includes a pair of orthogonal joints located one towards each of its ends.

In some structures it is desirable for the inner and outer frame members 24, 11 to have minimum widths for the reasons described below but a competing consideration however, requires the widths to be large enough to enable the structure to be adjusted in extent to embrace a predetermined range of opening sizes and a more particular objective of some of the inventions within, is for a single structure to embrace a range of common openings (in some cases, common within at least a territory); a further competing consideration for some structures is the need for the outer frame member to accommodate a lock and of course, in general, the smaller the depth the less expensive will the frame be.

In a more particular form of rectangular structure, the structures is further configured as a hinged security door having a ["security door form"] that is adaptable to embrace common door openings in a particular territory and the door sizes considered appropriate (after allowing for operating and fitting tolerances) are: height "H" between 2024 and 2042 (where the incremental height Delta H = 18) and width "V between 806 and 818 (where the incremental width Delta V = 12). In some forms of doors addressing the above requirement the following convenient size ranges have been adopted: HD: 2020 to 2045 (Delta HD=25) and WD: 800 to 820 (delta WD=20). Where the outer frame member is configured to suit a substantially conventional security door single point lock, the depth may conveniently be set to W= 40 MM, the Depth D=19, t=1.5, WT=3 so the channel 15 depth WC, referencing Fig 3 can conveniently be set to WC=2.5 +W+WT- WE= 2.5+35.5+3-10=31.0 where WE=10, WT=3 and W=35.5. In some cases and where a conventional multipoint lock needs to be accommodated, the following convenient sizes are suitable. W = 43 WC, WC= 39.0 MM.

If such structure were skewed by 10 MM so that an outer frame side member 11 became 10 MM lower (than it would be if the door remained rectangular), then the widest part of the gap of a simple mortise joint would be. very small indeed. Although these gaps are unfortunate, they are preferable to the common solution of fitting a rectangular door into a skewed opening to leave gaps through which insects have passage and/or where security is compromised or of reconstructing the door opening to suit the door.

Although joints could be configured to accommodate larger deviations, it is envisaged that in practice where the structures have a "security door form", the deviations will be within a range -3 degrees to +3 degrees. It should be said that the smaller is the width of the outer frame, the smaller will any comer gaps be for a give angle of skewing and this is another reason for minimizing the width of the outer and inner frame members.

In particular, where the outer frame members take a "security, door form"

MORTISE CORNER JOINTS

In some wings, some outer frame members are connected by mortise joints as shown in Fig 5 and 6, that includes a corner connector 40 that enables the included angle to be adjusted to slightly vary from the nominal angle. In one form, the comer connector comprises a pair of pairs of legs 41, 42 relatively disposed at a pre-determined disposition, a first legs 41 having side surfaces 45 separated by a distance substantially the same as the distance between side walls 18 of a first outer frame member 44, and edges 46 separated by a distance substantially the same as the distance between the internal walls of edges 21 and 22 of a first outer frame member 44;

and a second leg 42 having side surfaces 48 separated by a distance

substantially the same as the distance between side walls 18 of the second outer frame member 49 and edges 50, 51 angled to the internal walls of edges 21 and 22 of a first outer frame member 49 enabling the second outer frame member 49 to angularly displace relative to the second leg 42. In some forms, the corner connector comprises single castings and in orthogonal corner connectors the longitudinal axii of the legs are separated by 90 degrees.

In some forms, the first leg 41 is configured to be a tight press fit into the first outer frame member 44 by dent of a tapered leading end 53 (of width a little less than the distance between edge walls 21 , 22 of the first outer frame member connected to a portion 54 of greater width requiring the first outer frame member to elastically deform to . receive the first leg. In some forms, the second leg 42 has continuously tapered sides 50, 51 connected to a short portion 55 of greater width, the second leg being received into the second outer frame member 49. The second outer frame member is in some forms required to slightly elastically deform to receive the short portion 55 of greater width but not so as to give rise to forces that significantly affect the action of the spring described below. The second leg is angularly dispiaceable between the limit set by the tapered sides.

The second leg 42 supports a fixing block 56 that has a curved shoulder 57 defined by a constant radius R (in the plane of the wing) centred at feature point 59 midway between the comers of the abutting outer frame edges and this abuts a corresponding leading edge 58 of the second leg also defined by a constant radius R centred at a point 59. The second leg is intersected by a coned shaped aperture 61 configured to receive a threaded fastener 60; the aperture 61 connecting to an enlarged recess 62 configured to receive a protruding shoulder 63 that connects to the fixing block 56 and has a substantially axial treaded recess 64 in engagement with the fastener 60. The recesses 62 and 61 are sufficiently large to enable the second leg 42 to angularly displace within pre-determine limits about the fastener and shoulder 63.

In some forms, the fixing block 56 is configured to be a tight press fit into the second outer frame member 49 by dent of a tapered leading end 66 (of width a little less than the distance between edge walls 21, 22 of the second outer frame member connected to a portion of greater width requiring the second outer frame member to elastically deform to receive the fixing block 56.

In usage, the assembled outer frame is displaced to have the desired included angles at each corner, after which the mortise fasteners 60 are rotated to cause the respective shoulders 58 and 57 to be urged towards each other to a generate frictional reaction force that resists sideways relative displacement between the shoulders 57,58. The fastener can thereby be tightened to rigidly fix the end of the second leg to the fixing block to resistant reconfiguration of the outer frame from the configuration it was at the time of fastener tightening.

In a preferred form, an orthogonal connector (described in more detail below), referencing Fig 6, is included within the first leg 44 and within the fixing block 56; each including an elongated aperture 70, 71 (disposed orthogonally to the respective leg longitudinal axis and) configured to provide passage for the head 72,73 of a respective fastener 74,75 and being axially aligned with a respective nut recess 76,77 configured to retain white preventing respective nut 78,79 from rotating; the respective fastener 74,75 being in engagement with the respective nut 78,79 and extending to extend through a respective aperture 81,82 in the interior walls 21 to present a respective end 83,84 to the inner frame 9.

Joining members may be manufactured from any suitable material and by any suitable process; in some forms it comprises at least in part drawn steel tube, extruded aluminium, roll-formed steel (having the essential features described herein but modified to suit the roll-forming process), extruded plastic (including pvc) and they may be fabricated from multiple portions to have as a whole, the essential features described herein.

It will be appreciated that the construction described immediately above provides an adjustable linear joint enabling the effective lengths of outer frame members to be increased from a minimum length to a longer length where there is a gap (or increased gap) between the outer frame portions 100,101. Additionally, the structure may include a substantially U shaped cover 120, referencing Fig 8, to be placed between the exposed ends of the separated outer frame portions 100, 101 after the structure has been adjusted; the cover 120 having opposed legs 121 connected by a bridge 122 all having a wall thickness substantially the same as the sides 18 and outer edge 22 of the outer frame members; the legs 121 in application being slid over the connecting member 102 and under the sides 5 of the inner frame member to fill the recess created by the separation of the outer frame portions. In some forms, the external sides of the joining portion 102 include opposed external lonngitudinally elongated channels 123 configured to receive inwardly protruding longitudinally elobgated fins 124 that extend inwardly from the side walls of the opppsed legs 121 when the cover has been fully assembled over the joining member 102. In some forms, the cover 120 comprises a longitudinally elongated member having internal channel to enable to easily be cut to length to suit the width of the recess.

INNER FRAME & INFILL

In some forms, the inner frame extends along the entire periphery of the infill to provide a continuous peripheral recess that in some forms comprises a channel 15, referencing Fig 9, that extends along the entire periphery of the inner frame. In some forms, the channel 6 is U shaped having a depth D has a width WC, referencing Fig 3. In some forms, referencing Fig 1 , the inner frame is comprised of elongated inner frame members 24 connected at corners 25 configured to enable the respective channels 6 to be connected to form the continuous channel 15, referencing Fig 16, that extends along the entire periphery of the inner frame 9 by extending around each corner 25. The inner frame members may be manufactured from any suitable material and by any suitable process and may comprise drawn steel tube, aluminium extrusion, roll-formed steel (having the essential features described herein but a but modified to suit the roll-forming process), extruded plastic (including pvc) and in other forms, they may be fabricated from multiple portions to as a whole, have the essentia! features described herein.

In some forms, the infilling material 130, referencing Fig 3, is connected to the inner frame 24 by an edge return portion 131 that extends orthogonally to extend into an orthogonal fixing channel 132 referencing Fig 3 to be secured there by a fixing wedge 133 . In some forms, the fixing channel 132 extends sideways from a side opening 146 and in one form, one side Includes a ramped surface 147 that includes inclined surfaces terminating in orthogonal shoulders and the elongated fixing wedge 133 correspondingly includes a mating ramped surface 148 that includes inclined surfaces terminating in orthogonal shoulders, the latter inclined surfaces extending inwardly as they extend towards a leading edge 149 of the fixing wedge; the components configured such that as the fixing wedge 133 is dnven into the fixing channel 132, the ramped surface 148 displaces elastically away from the ramped surface 147 till the fixing wedge if fully wfthin the fixing channel corresponding to which the respective orthogonal shoulders abut to restrain the fixing wedge from leaving the fixing channel.

In the installed state, in some forms, the fixing wedge 133 fits tightly within in the fixing channel 132 to exert sideways disposed forces on both the return potion 131 and the ramped surface 147; these forces giving rise to forces on the return portion 131 restraining it against relative displacement and against leaving the fixing channel.

In some forms, referencing Fig 15, the return portion 131 includes fastener apertures 220 spaced along its periphery to provide passage for multipre headed fasteners 221 to extend between respective opposed apertures 222 within the opposed side walls of the fixing channel in the inner frame 24 to attach the infilling material to the inner frame, these fasteners 221 extending through respective apertures 220 coaxially aligned with apertures 222. In some of these forms, the fixing wedge 133 serves more to conceal the fixing channel 132 than to retain the Infilling material. In some of these forms, referencing Fig 32, the fixing channel has a reduced width and in some forms, the secondary return portion is omitted, and in some forms the fixing wedge is omitted.

In some forms, the return portion 131 is integrally connected to a secondary return portion 134 that is overlapped by the fixing wedge 133 which is configured to act on the return portion to restrain it against relative displacement and against leaving the fixing channel; in some forms, the secondary portion is disposed parallel the face of the infill 2. In some forms, the secondary return portion includes fastener apertures 135 spaced along its periphery to provide passage for multiple headed fasteners 136 to engage, referencing Fig 8, in respective multiple apertures 137 in the inner frame 24 to attach the infilling material to the inner frame, in which case and in some forms, the fixing wedge 133 serves more to conceal the fixing channel 132 more than to retain the infilling material.

It will be appreciated that infilling material described above can be easily removed by simply removing the fixing wedge and/or fasteners and it can easily be replaced by replacing these fixing wedge and/or fasteners enabling the infilling material to be removed for repairs, replacement and cleaning and also allowing the infilling material to be fitted at the last minute in the manufacturing/fitting process; this allowing for the separate sale of infilling materials.

Some structures, referencing Fig 13, 14, incJude infills that alternatively or additionally include one or more bars 150 that in some forms are configured as substantially rectangular hollow tubes 151 referencing Fig 14, having a continuous axial recess 152. Each end of each bar is adapted to occupy/mate within opposed apertures 154 of the inner wall 155. In a particular form, each end of bar includes an axially elongated aperture 160 to receive a fastener 157 that extends through an respective aperture 158 in the respective inner wall 159 to extend through the fixing channel 132 to extend through another aperture of the inner frame to occupy and engage in threaded engagement with the elongated aperture to engage 160; in some forms each end of each bar is connected in a similar manner.

in some structures, referencing Fig 13, 14, the bars 150 abutt the inner wall 155 and opposed apertures 154 are omitted.

in some forms, the aperture 152 extends from one end of the bar to the other and some forms, an additional continuous axial recess 161 is occupied by one or multiple enhancing elements 162 resistant to sawing and cutting (that in some forms comprises hardened steel rod/s that in some forms is configured to be able to freely rotate in response to attemped sawing). In some forms, the element 162 is separated from the walls of recessw161sby anulii of insulating tape to amongst other things, impede galvanic corrosion between the infilling material and the inner frame; this being particularly relevant when the materials are different.

Some structures referencing Fig 30 include an infill including infilling material 230 having a protruding return portion 231 that extends sideways along its peripheral edge (similarly as described above) to occupy a side recess 232 of the inner frame. In application, each edge of the infilling material 230 is inserted into a slotted aperture 233 through the mouth 234 of a respective inner frame member and subsequently, opposed inner frame members are displaced towards each other to cause the return portion 231 to occupy the side recess 232 and to overlap the fixing shoulder 235. At which time, a fixing wedge 236 (that in some forms Is a resilient and elastically deformable member) is driven through the mouth 234 alongside the infilling material 230 adjacent to the second fin 237 to urge it further into the side recess 232 and to prevent the return portion 231 from displacing from the recess. It will be appreciated that the mouth 234 and slotted aperture 233 need to be wide enough to provide passage for the return portion 231 ; the fixing wedge may take the form of a longitudinally elongated member having the cross- section shown or it make take the form of multiple discrete portions having the same cross section.

In some forms, the surface 240 of the second fin 237 may be textured and it may be to better retain the fixing wedge 236 and/or strip described below; the ramping on the second fin including inclined surfaces that extend inwardly as they extend away from the fin mouth and the fixing wedge may include a mating ramped surface that extend outwardly as they extend inwardly. When installed the surface engage to retain the fixing wedge within the slotted aperture 232. The fixing channel is preferably further configured to have a width such as to exert a sideways force on the fins in the assembled state.

In some forms, the infilling material 130, referencing Fig 31 , is connected to the inner frame 24 by an edge return portion 131 that extends orthogonally to extend into an orthogonal fixing recess 240 referencing Fig 31 that extends sideways from a side opening 241 of the inner frame. In some forms, the return portion 131 includes fastener apertures 220 spaced along its periphery to provide passage for multiple headed fasteners 221 to extend from respective apertures 243 within the side wall of the fixing recess in the inner frame 24 to attach the infilling material to the inner frame, these fasteners 221 extending through respective apertures 244 in the return portion coaxially aligned with apertures 243. In some forms, the fasteners engages in threaded engagement within the respective aperture 220. In some of these forms, a cover strip is employed to conceal the fixing recess 240.

In some forms, as shown in Fig 13, the return portion 131 and secondary return portion 134 are separated from the walls of the fixing channel 132 by an insulating strip 247 that extends the entire length of the return portion to maintain the infilling material separated from the inner frame to amongst other things, impede galvanic corrosion between the infilling material and the inner frame; this being particularly relevant when the materials are different.

In some forms the infilling material comprises metal sheet (that in some forms includes secondary portion/s) that in some forms comprises perforated s/s sheet or perforated aluminium sheet and in some forms or additionally, the Infilling material may comprise fiberglass mesh.

In some forms, the infilling material comprises discrete strips of material that extends between sides of the inner frame and having return portions at each to be secured by any of the methods described above. In some forms each return portion is connected to a secondary return portion to enable fixing by any of the methods described.

Referencing Fig 3, 30 and 31 , the inner frame members 24 are rigidly connected by corner joints that in some forms, referencing FiglO-12, include a joining member 323 having legs 324 that occupy the longitudinal hollow of the inner frame member described in Fig 3, 30 and 31 these being hollows 320, 321 and 322 respectively within the abutting inner frame members, these legs 324 extending internally to abut opposed walls of the hollows of the respective inner frame members that in some forms required to slightly elastically deform to receive the respective leg 324 to form an interference fit that acts to restrain the inner frame members participating in the joint against relative displacement. In some forms, the joining member comprises a sandwich construction comprising a first side member 325, a second side member 326 and sandwiched between a steel strengthening member 327 supported about multiple cylindrical bosses 328 that extend from the first side member 325 to extend through apertures 329 in the second side member 326 to be peened over to form a rigid sub-assembly.

In some forms, referencing Fig 17-19, the inner frame includes side wall corner joints 170 to assist the connected inner frame members 24 to remain connected; these and preferably included on both sides of each comer of the inner frame. In some forms, each side wall joint includes a side wall connector 171 having a first arm 172 extending within an elongated recess 172 in an inner frame member and a second arm 173 extending within an elongated recess 174 in the other inner frame member, each recess 172, 174 connecting to provide an angled elongated continuous recess. Each recess 172,174 extends outwardly from the inner face 175 of the respective inner frame member and having a width substantially the same as that of a respective associated arm 172,173 and a depth substantially the same as the thickness of the side wall connector 171.

The arms 172,173 include sideways extending wings 177 that extend beyond their general width so as to protrude so that when the comer connector is forced into the recesses 172, 174 the wings 177 gouge mating recesses which they occupy to form a tight fit to restrain the connecting member 171 within the recesses.

In some forms, referencing Fig 17 to 19, the comer connector 171 is substantially planar and in some forms, either additionally or alternatively, adhesive is applied between the side wall corner joints 170 and the recesses 172, 174 for reasons that include assisting or better connectting the comer connector to the inner frame and/or to improve the manufacturing process

KNOCK- DOWN "DIY" VERSION '

Some forms of structure, referencing Fig 20 to 22 are further configured such that the infill is configured as multiple smaller sub-infills 180 and some infills comprise a pair of substantially identical sub-infills, each the mirror image of the other with inner frame member 181 (of the first sub-infill) and an adjacent inner frame member 182 (of a second sub-infill) abutting and in a particular form, referencing Fig 21 , the inner frame, member 181 and 782, have identical cross-sections that take the form of the cross- section of the inner frame members 24 on the other sides except the sides 5 are truncated but each includes a respective fixing channeM 32.

This construction lends itself to hinged screen doors that may be configured in "knock-down" form to fit within a carton or other retail packaging, the door being assembled later by a home owner handyman or tradesman after being transported by passenger vehicle. In some such hinged doors, referencing Fig 4, having a height H and width V the sides of the outer frame consist of a longer outer_frarne portion- 191 (that may be packed diagonally into a carton by) having a length L = sq root [(V² +(H/2)²] and a shorter _outer_frame portion 192 having a length = (HW.); where the identical infills have a height A/2 and a width B. By way of example, consider a structure comprising a door having a height H=2000 MM and a width V=800 MM, each longerputeMtame portion 191 is configured to have a length L = [sq root (1000² + 800²)] ~ 1.33 M and shorter _outer_frame portion 192 has a length (2000 - 1330) - 0.7 M; these outer frame members dearly fitting within a carton that will fit with a sedan vehicle.

Each set of outer frame portions 191 , 192 may be connected by any convenient means including the linear connector described above taht including the elongated connecting member. In some forms, referencing Fig 22, employing bans, the sub infills are held together by bars 320 that extend within opposed additional continuous axial recesses 161 to be secured there by a rivet 183 that extends sideways through coaxial apertures in the side of the inner frame member 181 and the bar 320 and another rivet 183 that extends sideways through coaxial apertures in the side of the inner frame member 182 and the bar 320. In some forms, referencing Fig 20, sub infills are held together on a first side by strips 184 that extend within channel 6 of the inner frame member to be secured there by one or multiple fasteners185 that extends edgeways through coaxial apertures in the strip 184 and the base 10 of the inner frame member and one or multiple fasteners 185 similarly extend edgeways through coaxial apertures in the same stripl 84 and the base 10 of the adjacent inner frame member; the other sides of the pair of sub-infills being similarly connected.

LOCKS. HINGES & ROLLERS

Where a structure, takes the form of a hinged or sliding door it comprises a wing having a substantially rectangular infill and an outer frame comprising two pair of opposed outer frame members where wherein each said outer frame member includes a pair of outer frame portions connected by a telescopic joint to be relatively displaceable to change the length of the respective outer frame member, each said outer frame member being connected to each outer frame member of the other pair by an adaptable corner joint and the outer frame member corresponding to the closing edge is adapted to support a lock 300.

In some forms (and in particular, when the lock is a conventional security door lock) this comprises making an aperture 301 in the outer edge of the outer frame to enable a lock body 302 to be inserted into the outer frame to in-part occupy recess 19 and making apertures 303 in the opposed sides to enable a cylinder 304 to be attached to the lock body and to extend through the sides of the outer frame to enable a drive rod 305 and handle back plate fixing spigots 306 to extend through the sides of the outer frame; in some cases, these apertures are configured to enable the lock to be fitted either end up so accommodating the door to be fitted either end up (as this is an objective of some of the patents^' described within).

Being able to invert the wing, requires the outer frame to have enlarged aperture/s 303 that enable the lock communicating lock components to have passage through the outer frame irrespective of which way up the wing is but with the lock always orientated so that downward action of an unlatching handles causes the bolt to retract.

Where channel 16 is provided, and where the tock comprises a substantially conventional security door lock (or a similar lock) the lock has upper and lower fixing tabs 307 that are attached within channel 16 by fasteners as would be one leaf of the hinges. These apertures a pre-determined and can be machined or pressed into the outer frame member during manufacture of the door.

It will be appreciated, that because the lock is fixed to the outer frame, it will displace together with the outer frame as the inner frame is displaced relatively to the outer frame during adjustment (if the lock is fitted at that time) and this requires the aperture/s 303 to be even further enlarged to enable the lock communicating lock components to have passage through the outer frame irrespective of how (within the predetermined ranges) the door is adjusted.

In general, the structure may be configured such that the required increase in width is provided by the outer frame opposed side member being, displaced to protrude further from their associated channel 6 and in some cases, to protrude an equal distance from their associated channels 6 up to a pre-determined convenient distance.

Referencing Figs 25 to 28, the apertures in the inner frame can be pre-made as enlarged apertures configured to enable the cylinder, spigots and drive rod to have passage through the inner frame irrespective of its disposition relative to the outer frame and for the particular structures within the ranges determined by the need for the wing to have outer dimensions (as described previously): height = HD to HD + Delta HD and width = WD to WD + Delta WD.

Alternatively, once the door has been assembled and adjusted, referencing Fig 28, apertures can be made in the inner frame member (with reference to the apertures in the outer frame) to enable the cylinder, spigots and drive rod to have passage through the inner frame; these apertures can conveniently be made with a conventional hole saw 308 guided by a template attached relative to the outer frame

Where the structure configured as a sliding door, referencing Fig 24, the outer frame member corresponding to the lower edge of the structure will usually be adapted to support a roller 310 and may comprise making spaced elongated apertures 311 to enable the roller assemblies to be inserted into the outer frame. Where the structure configured as a hinged door, referencing Fig 23, the outer frame member opposed to the closing edge will usually be adapted to support spaced hinges 312 that may comprise making spaced apertures to enable hinge the fixing screws to be attached.

In some forms, referencing Fig 38 of PCT/AU2O09/0C0O81, the inner frame is adapted to included a slotted aperture 183 relative to which the infilling material is attached and in some forms the infilling material comprises substantially planar material that in some forms, referencing the Figures in PCT/AU2009/000081 , includes glass 210 attached to the inner frame 3 by a resilient and/or elastic grommet 211 that acts to support the glass or other material and in some forms, while holding it separate from the inner frame.

In some forms of wings and being particularly applicable to doors, the inner frame is held spaced from the outer frame in the vicinity of the fixing tabs 302 and the hinges 312 by an adjustable spacer that in some forms comprises a conventional Rivnut, referencing Fig 29, to restrict the outer frame from being inwardly displaced as may occur during attempted forced entry. Each Rivnut includes a substantially cylindrical joint boss 331 that is supported in the outer edge 22 of the outer frame member 11 to extend towards the inner edge 21 where It is disposed cbaxially relative to an aperture 332. The joint boss 331 includes an axially elongated threaded aperture 334 that supports a threaded fastener 333 (such as a grub screw) that is accessible to enable a tool (such as an A/an key) to be inserted into the fastener drive recess 335 to rotate the fastener and in some situations, to cause it to protrude from the joint boss 331 to act on the inner frame member 24 to displace the outer frame member 11 away from the inner frame 9. In some forms the joint boss 331 includes a substantially cylindrical end 337 of reduced diameter that extends through an aperture33S in the outer frame member to be outwardly peened over (to form a ridge 339 that overlap the outer frame member) to retain it attached to the outer frame member.

ADDITIONAL FASTENERS

After the structure has been adapted to suit a particular opening, it can be strengthened by the application of additional fasteners; some such being applied to the side/s of the inner frame to extend through and mate in threaded engagement in apertures in the sides of the outer frame - in some cases these being applied towards the upper and lower ends of the structure on both sides and/or in some cases being applied adjacent to the angled end of each inner frame member to better support the respective end of the inner frame; and/or in some cases being applied adjacent to the lock and hinges to lend rigidity to the structure and to amongst other things, to restrict the outer frame from being inwardly displaced relative to the infill as may occur during attempted forced entry; and some such being applied to the edge/s of the outer frame to extend through and mate in threaded engagement in apertures in the edges of the legs 41 , 42 of each corner connector .
