Detailed Description of Embodiments Consistent with the Concepts of the

Inventions

GENERAL

Reverting to the problems with 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, DIY 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, referencing Fig 35, 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 within are described (in some places) with reference to wings including doors, and in particular with reference to those shown in the figures, 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), that in some forms includes flat glass, woven steel mesh, fiberglass mesh, perforated sheet metal, bars or a combination thereof or any other suitable material. In some forms the structure 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, the outer frame 3 supports the infill 2.

In some forms, referencing Fig 10, 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 referencing Fig 10 and 11 , 12 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 22 (or outer edge wall 21) connected to a side 18 and in some cases, connected to opposed sides 18; (although not limited to, in some forms) having a substantially rectangular cross- section and including a hollow 19 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 10; 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 WT deep.

Hollow rectangular outer frame members are well suited to many structures including wings and in particular 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 mOrtise 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, referencing Fig 37, but the structures described herein are not limited to the examples described.

Some structures have corner joints as described in Patents included by reference. Some structures referencing Fig 11. Some have at least one adaptable corner joint 23 as described herein denoted "LJ-X/YY" (X/YY indicating the location]; adaptable corner joint facilitating changes in the effective length of associated outer frame members (as described below); in some applications corner joints joint automatically adjusts in response to changes in length of outer frame members.

In application, it may be necessary to change the effective length of a side to render the structure suitable for a larger opening; the Objective being to fill 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 when each outer frame member is adjacent to a corresponding inner frame member 24 along its length, and where each corner has an included angle equal to its respective nominal included angle and where after the structure has been adjusted to a larger extent the outer frame members are parallel to their respective configurations in the smallest configuration and where each corner joint has an included angle that is equal its respective nominal angle and the joint is referred to as being "perfect" and where after adjustment, the outer frame members will become not parallel to their respective configurations in the smallest configuration resulting in at least one corner joint having the configuration of a "pseudo mortise joint" and having an included angle ["Alpha"] that differs (by a deviation) from its respective nominal angle, and if the joint were an orthogonal mortise joint, the joint would take the form of a pseudo orthogonal joint.

In a particular form of such a 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 is adjacent and parallel to a corresponding inner frame member 24 along its length, and

· 2) nominal angles of ninety degrees at each corner, and

3) the outer frame, referencing Fig 11 includes an upper outer frame member 31 , a lower outer frame member 32, a left hand 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 orthogonal joints located one towards each of its ends denoted OJ-X.

In some structures it is desirable for the inner and outer frame members 24, 11 respectively 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 pre-determined 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, the structures is further configured as a hinged security door having a ["security door form"] that is 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 = 46.6 MM, the Depth D=19, t=1.5, WT=3 so the channel 15 depth WC, referencing Fig 10, can conveniently be set to WC=2.5 +W+WT- WE= 2.5+46.3+3-13 ~ 39.0 where WE=13, WT=3 and W=46.3 these sizes being compatible with a conventional multipoint lock.

If such structure were skewed by 10 MM (so that each corner takes the form of a "pseudo orthogonal mortise joint") 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 between the comer cover flap (cut to size orthogonally) and the shoulder 170 would be very small. 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 corner 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 INCL ADAPTABLE JOINTS

Outer frame members may be connected by corner joints described in Patents included herein by reference but some outer frame members include those referencing Fig 10 and 11 and 12 are connected by joints each having a corner connector 40 that with one or both legs to enable the included angle to be adjusted. In some forms, each corner connector comprises a pair of pairs of legs 41 , 43 relatively disposed at a pre- determined angle, a first leg 41 (extending into the hollow 19 of a first outer member 42) and a second leg 43 (extending into the hollow 19 of a second outer member 44) each having opposed substantially parallel edge surfaces 45 separated by a distance substantially the same as the distance between opposed inwardly raised shoulders 46 that project into the hollow 19 of the respective outer frame member and each corner connector having elongated portions 50, having edge surfaced angled to the internal walls of edges 21 and 22 of the respective outer frame member enabling the outer frame .members to angularly displace relative to the associated leg 41 ,42. In some forms, each corner connector comprises single castings. In some forms, the legs 41 , 43 are connected by a bridge 47,48 respectively that includes apertures 48,49 respectively and in some forms aperture 48 is circular having a diameter substantially the same as the fastener the extends through it, and In some forms, aperture 49 is oval having a depth substantially the same as the fastener that extends through it and being elongated in width to enable the fastener 79, fixing block 63 and associated outer frame member to angularly displace - relative to the respective corner connector.

In some forms, referencing Figure 12, the outer frame members from ends 55,56 respectively inwardly projecting shoulders 57, 58 that extend away from the ends 55,56.

In some forms, referencing Figure 12, the outer frame members from ends 55 and 56 respectively, are formed to have outer elongated edge and side recesses 60,61 respectively configured to receive the flaps or wings 221 and edge plate 220 of a corner cover 20, the recesses 61 being correspondingly bounded by shoulders 170 along the interface with the unformed side of the respective outer frame member. In some forms referencing Fig 21 , the corner cover 20 comprises a flat profiled member 222 having fold lines 223 of reduced thickness enabling the member 222 to be folded to assume the configuration of Fig 20, a configuration that enable it to can occupy the surface recesses of the corner it covers while residing within the channel 15 of the inner frame. For convenience, the flaps or legs 221 include orthogonal cutting channels 224 to receive a cutting tool so the flaps may more easily be cut to length so each respective wing 221 occupies a respective recess 61 while abutting a respective shoulder 170 while each respective edge 220 encloses a respective recess 60.

In some forms, each leg 43 is connected to a respective fixing block 62, 63 that can be fixed relative to respective outer frame members 42,44; in some forms the fixing block 63 has a curved shoulder 65 defined by a constant radius R (in the plane of the wing) centred midway between the respective opposed shoulders 45 and this abuts a corresponding leading edge 57 of the second leg 43 defined by a constant radius R having the same centre. The connecting member includes aperture 71 configured to receive a threaded fastener 79 that extends to engage in a recess 75 in the fixing blocks 75. As mentioned above, in some forms, corresponding aperture 49 takes the form of an oval to enable the leg 43 to relatively angularly displace about fastener 79 within pre-determine limits. In some forms, the fixing blocks are configured to be a size for size fit within the hollow 19 of the respective outer frame member.

In some forms, fixing block 62 has a curved shoulder 64 defined by a constant radius R (in the plane of the wing) centred midway between the respective opposed shoulders 46 and this abuts a corresponding leading edge 56 of the firsts leg 41 defined by a constant radius R having the same centre. The connecting member includes aperture 70 configured to receive a threaded fastener 78 that extends to engage in a recess 74 in the fixing blocks 62. As mentioned above, in some forms, corresponding aperture 49 takes the form of circle having a diameter substantially the same as that of fastenet 78 to prevent the leg 41 from relatively angularly displace about fastener 79

In some forms, referencing Fig 13 to 15, each fixing block 56 includes an outwardly displaceable member 71 and inwardly displaceable member 72 that may comprise pins that extend between aperture 74, 75 and the outer edge 20 and the inner edge 21 respectfully of the associated outer frame members and being configured such that when abutting the sides of the fastener 78, 79 respectfully, they each extend to form and to extend into recesses in the edges 20 and 21 of the respective outer frame members 42, 44; this being achieved by the coned end 170 of the respective fastener being driven between the inner ends of the pair of pins 71,72 to cause these ends to slide up the walls of the cone while displacing outwardly.

In usage, a substantially rectangular wing, referencing Fig 1 , 11 has fixing blocks 62,63 respectively are held restrained against the bridges 47,48 by fasteners 78,79 whose heads 80,81 respectively are held spaced from the bridges 82,83 by removable or destructable spacers 84, 85 Each outer frame member is then displaced from the corner connectors between which it extends (by means that may include use of the orthogonal connecting members) to have the desired effective lengths (for clarity "effective length" and where the context requires it "length", means the distance between corner connectors which the respective outer frame member extends); after which, the spacers 84,85 are removed or crushed one by one as the fasteners 78,79 in the entire structure are lightly tightened to drive respective pairs of pins 71 ,72 outwardly to form recesses in the side walls as described above (to fix the respective outer frame members relative to their respective corner connector); after which the screws 79 may be lightly loosened (while still retaining the pins outwardly displaced) to enable the outer frame to be skewed as required; subsequently the fasteners 79 are tightened to rigidly fix the outer frame. ^• In summary, the effective length of each outer frame member may be changed by operation of either one of the associated orthogonal joint fasteners and the included angles of each corner may automatically change in response to changes in length or changes of configuration of outer frame members (before final tightening of the corner fasteners 79).

INNER FRAME & INFILL

The Infill may comprise any means of filling the space between the outer frame members having means of being attached to it. Some structures include an infill as described in the Patent Specifications included herein by reference.

In some forms, the inner frame 9 extends along the entire periphery of the infill 2 to provide a continuous peripheral recess that ih some forms comprises a channel 15, referencing Fig 5, that extends along the entire periphery of the inner frame. In some forms, the channel 6, 15 is U shaped having a depth D has a width WC, referencing Fig 8. In some forms, referencing Fig 4, 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 5, that extends along the entire periphery of the inner frame 9 by extending around each corner.

In some forms referencing Fig 4 and 9, the inner frame corner joints are substantially butt joints where the horizontal members extend between the vertical frame members and where the horizontal members include screw apertures 183 whereby to receive fasteners 184 that extend through apertures 185 in the base 10 of the respective vertical member; it being appreciated that the base of vertical frame members adjacent to the horizontal members are removed to enable the recess 6 to extend round the corner as shown in Fig 19; it will be further appreciated that the wing 80 portions of the vertical and horizontal outer frame members participating in a joint comprise mortise portions again to enable enable the recess 81 to extend round the corner as shown in Fig.19.

In some forms, each inner frame member 24 includes an elongated wing 80 referencing Fig 10, 26, 41 that extends along substantially the entire periphery of the respective inner frame member to provide a continuous offset recess 81 to receive the infilling material return portion 102 (a sideways extending portion that may extend along the entire periphery of the infilling material). In some forms it comprises a channel 82 having a side opening 89 of width Q and a hollow bounded by the base 10, a

supporting wall 93, the inner wall 92 and the return wall 91. Within the hollow is a peripherally elongated fixing bar that occupies some of the hollow but which leaves clear sapace substantially Q in width. The return portion 102 extends sideway to extend through the opening 89 to occupy the clear space to be fastenered there by fasteners 86 referencing Fig 26 to 32 and 42, spaced along the channel 6 of the inner frame and extend inwardly (by having threaded shank portions that extend in a direction substantially coplanar with the face of the wing) to extend through the infilling material to extend into a fixing bar 87. In some forms, referencing Fig 26, the fasteners are in threaded engagement with the base 10 but having clearance holes in the fixing bar 87; in some forms, referencing Fig 27 to 31 , the fasteners are in threaded engagement with the fixing bar but not the base 10. In some cases the fixing bar comprises an extension to the inner frame, in other cases, the fixing bar 88 is a separate member housed within the hollow.

In some forms, the surface of the fixing bars 87,88 are textured and it may be ramped 130, the ramping including inclined surfaces 131 that extend inwardly as they extend away from opening 89. In some forms, the infilling material comprises substantially planar material formed to have an elongated peripheral return portion 102 described above that extends sideways to extend into the recess 81 and in some forms the return portion extends along the entire periphery of the infilling material. The infilling material may comprise any suitable material including woven steel mesh and perforated sheet metal and flexible materials such as fiberglass mesh where the return portion is formed on fitting. The infill may an adapted inner frame to suit bars attached to the or an adapted inner frame as described in patents included herein by reference.

In summary, in part, the peripheral channel is occupied by a fixing bar so the return portion is between the said fixing bar and a wall of the recess and fasteners extend through the said recess wall to extend through the infilling return to be in threaded engagement with the fixing bar to better retain the infilling material.

In some forms the fasteners are tightened to draw the return towards the recess wall and/or to sqeeze the return between the recess wall and fixing bar to better retain the infilling material and/or to urge the adjacent infilling material outwardly.

In some forms, including those where the infilling material is of a different material to the inner frame material and galvanic corrosion is to be prevented, for example, the infilling material is of stainless steel woven mesh and the inner frame is of aluminium, the infilling material is separated from the inner frame by a non-conductive gasket 104 (that in one form comprises PVC) that extends peripherally to enclose the return portion 102 and adjacent material; it will be appreciated in this case that the fasteners extend through apertures punctured in this gasket. In one form, the gasket includes sideways wings 104 configured to engage with the walls of the recess 81. In some forms, the gasket is a material softer than the woven mesh that if squeezed will deform to protrude into spaces on the surface of the woven mesh and into the spaces adjacent to the ramped surface of the fixing bar 87,88 so that to better retain the infilling material return portion within the fixing recess; dislocation of the return portion requiring shearing of the gasket in a direction parallel the base 10.

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 essential features described herein.

In some forms, the infill may include glass attached to the inner frame 3 by a resilient and/or elastic grommet that acts to support the glass or other material while holding it separate from the inner frame as described in Patents included by reference.

CENTRALIZING/POSITIONING THE INFILL ^' ,

In some structures, referencing Fig 34,35 the infill 2 may be centrally located in the outer frame or otherwise relatively aligned to suit particular situations or needs. In some structures this is achieved by means of orthogonal joints 120 situated relative to ends of outer frame members, they having a boss 121 that is supported between in the outer and inner edge 21,22 of the respective outer frame member. Each boss 121 includes an axially elongated threaded aperture 123 that supports a threaded fastener 124 (such as a grub screw) that is accessible to enable a tool (such as an Alan key) to be inserted into the fastener drive recess 125 to rotate the fastener to cause it to protrude through an aperture 126 in the outer frame to act on the associated inner frame member 24 to displace the outer frame member 11 away from the inner frame member 24 (not shown). In some forms the boss 121 substantially comprises a fixing block 56 having the pins 71 ,72 replaced by a single elongated fastener 124.

In some forms, the drive recess 125 is accessible through a coaxial aperture 126 in the outer wall 22 and in some situations, the drive recess 125 (in an inverted fastener) is accessible through a coaxial aperture 127 in the wing 80 and a corresponding recesses 128 and 129 in the base 10 and inner wall 21 respectively - in this case the fastener 124 would always at least protrude into aperture 128 and the boss 121 would be free to displace in the associated hollow 19. This latter configuration being suitable for window screens and shutters as well as other applications.

Referencing Fig 11 , we see an orthogonal joint towards each end of each outer frame member. The fasteners in these may be turned to displace the ends of the outer frame members to their desirable configurations relative to the infill (when the spacers 85 are in-situ); for example the fasteners in either OJ-U/LH and/or OJ-U/RH may be displaced inwardly to lengthen the upper outer frame member 31.

LOCKS, HINGES & ROLLERS

Where a structure, takes the form of a hinged or sliding door it comprises a structure having a substantially rectangular infill and an outer frame comprising two pair of opposed outer frame members where each outer frame member has associated a adaptable joint and is connected to each outer frame member of the other pair by a corner joint and where the outer frame member corresponding to the closing edge is adapted to support a lock 200.

In some forms (and in particular, when the lock is a conventional security door lock) the door is prepared by making an aperture 201 in the outer edge of the outer frame to enable a lock body 202 to be inserted into the outer frame to in-part occupy recess 19 and making apertures 203 in the opposed sides of the outer frame to enable a cylinder 304, 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 207 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 the lock comprises a substantially conventional security door lock (or a similar lock) the lock has upper and lower fixing tabs 208 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 207 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 15 and in some cases, to protrude an equal distance from their associated channels 6 up to a pre-determined convenient distance and similarly with the height. Referencing Figs 37 to 40, the apertures in the inner frame 207 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 40, 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 209 guided by a template attached relative to the outer frame

Where the structure configured as a sliding door, referencing Fig 2, the outer frame member corresponding to the lower edge of the structure will usually be adapted to support a roller 210 and may comprise making spaced elongated apertures 211 to enable the roller assemblies to be inserted into the outer frame. Where the structure configured as a hinged door, referencing Fig 1 , the outer frame member opposed to the closing edge will usually be adapted to support spaced hinges 212 that may comprise making spaced apertures to enable hinge the fixing screws to be attached.

In some forms of wihgs 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 by an adjustable spacer that in some forms comprising an adapted orthogonal joint where aperture 126 has been omitted, to restrict the outer frame from being inwardly displaced as may occur during attempted forced entry.

ADDITIONAL FASTENERS

After the structure has been adapted to suit a particular opening, it can be strengthened by the application of additional fasteners; some 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 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 .

A SUBSTANTIALLY RECTANGULAR WING EMPLOYING THE INTEGERS

Notwithstanding any other forms of structures employing combinations of the integers described within this patent specification (that includes the patent specifications included herein by reference) that may fall within the scope of the inventions described herein, a form of one of the inventions comprising: a wing having a substantially rectangular infill and an outer frame comprising two pair of opposed outer frame members where wherein each outer frame member has associated a pair of adaptable corner joints to be relatively displaceable to change the effective length of the respective outer frame member, each outer frame member being connected to each outer frame member of the other pair by the adaptable corner joint will now be described, with reference to the manner in which it can be adapted to suit a particular opening.

Prior to adjustment (and fitting if the structure comprises a door), the wing would be assembled by assembling the outer frame members to the peripheral channel 15 of the inner frame. The wing, referencing Fig 1 , would then be adjusted to suit a particular opening by:

• If the wihg is further configured to be a door, making the apertures in the outer frame member to receive the lock

• Assembling the outer frame to the inner frame and lightly tapping the outer frame members till they have assumed a configuration corresponding to the smallest extent of the wing.

• Loosely tightening fasteners 79 and 78 while spacers 408 are in place (while the wing is substantially rectangular)

• Adjusting the length of a particular outer frame members by equally rotating

fasteners in the closest orthogonal joints in the outer frame members connected to the particular outer frame member; doing likewise for all outer frame members

• Removing the spacers 408 and tightening all fasteners 78

• Loosening fasteners 79 and skewing the wing as required and then tightening fasteners 79 to flatten the spacers and allow the fastener 79 to drive the pins 71 ,72 outwardly

• If the wing is further configured as a hinged door, attaching the hinges to outer frame member 33.

• Cutting the wings of corner wrap covers 20 to length and applying them to occupy the corner surface recesses

· If a lock is required, cutting the apertures in the outer frame member with the hole saw to accommodate the lock by using a template referencing the inner frame.
