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 afl the different common openings.

Such adjustable doors would be manufactured without reference to particular openings (which is time consuming and expensive) and by modem manufacturing techniques and systems resulting in reduced manufacturing costs and unproved 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 this objective. Doors of course could be configured to embrace other predetermined ranges to suit common sizes in Other jurisdiction or territories.

Notwithstanding the inventions are described (in some places) with reference to wings, they are not limited to such structures. In some forms, a structure 1, referencing Fig 1 to 4, includes an infill 2 (not limited to, but) that may take the form of 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 and outer frame 3; the infill 2 and outer frame 3 configured to be relatively disposed and in some forms the outer frame 3 supports the infill 2 and in some forms they are configured to mutually overlap.

In some forms the infill is bounded by a return 4 that extends along the periphery of the infill and although not limfted 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, referencing Fig 2 to 3, 5 to 6, and 8 to 10, are hollow and include a longitudinal recess 19, an outer edge wati (or outer edge) 22 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- sectϊon and including a hollow 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.

Hollgw 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 materia! and by any suitable process; they may 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 they may be 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 Australian security door lock body. For convenience only, the outer frame employed in the figures accommodates a substantially conventional Australian security door lock body but the structures described herein are not limited to such frames. The outer frame members employed in the figures is defined by D=19MM, W=40 MM, t= 1.5 MM.

In some structures, at least one outer frame member 11 has an associated linear joint 23 that may be adjusted to change the effective length of the outer frame member (i.e. to change the separation of the outer frame members to which the said at least one outer frame member 11 is connected) 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, is 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 (and in many cases, the objective being to fill the opening with the structure with only working clearances). In some structures, after the structure has been adjusted to a larger extent the outer frame members are parallel to thetr respective configurations in the smallest configuration; in which case, each corner joint has an included angle that is equal its • respective nominal angles and each 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. The corner joints described herein have structural integrity even when their included angles differ from their respective nominal angles.

Outer frame members 11 , referencing Fig 4 to 6, are connected by corner joints 12 that in some forms comprise butt joints and in others mortise joints that in some forms are as described in the Patent Specifications included by reference. In some forms of structures, each corner joint remains adaptable till a corner fastener 13 is tightened to render the comer joint rigid; in some forms the comer fastener drive recess is accessed through an aperture 270 in an outer frame member 11 having a diameter small than the head 272 of the corner fastener and being just large enough to receive a drive tool.

A particular form of structure includes an infill bounded by an inner frame on ail sides that is bounded by an outer frame on all sides, In a more particular "rectangular structure", the structure is characterized by the inner frame being substantially rectangular and the outer frame having: 1 ) a smallest configuration where each outer frame member abuts (along its entire length) a corresponding inner frame member 24,

2) a nominal angle of ninety degrees at each corner.

In some structures, it is desirable for the inner and outer frame members 24, 11 to have minimum widths for the reasons described below; a competing consideration for some structures 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 openings common within at least some territories; 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. fn a more particular form, the structures comprise a hinged security doors that are adaptable to embrace common door openings in Australia, the doors having a height "H" between 2020 and 245 (where the incremental height h=25) and a width "V" between 805 and 820 (where the incremental width v = 15). Where the outer frame member is configured to suit a substantially conventional Australian security door lock, the depth may conveniently be set to W = 40 MM (and the Depth D=19 and t=1.5) such a depth providing up to 35 MM overlap while still providing 5 MM of overlap, thus easily providing the required incremental distances that can be provided iπ-part by opposed sides of the wing; and the channel 15 depth we can conveniently be set to 40 MM, referencing Fig 34. If such a structure were skewed by 10 MM so that an outer frame side member 11 became 10 MM tower (than it would be if the door remained rectangular), then the widest part of the gap of a simple butt joint would be approximately (10/800) x 40 = 0.5 MM, a very small amounts indeed and other structures characterized by similar ratios will have corresponding similar gaps. Where the first end wall 81 consisted of angled portions 86, the widest part of the gap would be approximately 0.25MM. 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. Where the structure was skewed by 10 MM as described above, the corresponding deviation would be 10/800 x 180/Pi degrees [approx 0.75 degrees].

Although joints could be configured to accommodate larger deviations, it is envisaged that in practice where the structures are configured as doors, the deviations wilt be within the 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.

Some outer frames additionally include extensions 14 to the sides 18 that form an Outwardly disposed peripheral channel 16 that in some forms is w deep and configured to receive the fixing tabs of a lock, in a particular format it is 3 MM deep. INNER FRAME & INFILL

In some forms, the inner frame extends along the entire periphery of the infill to provide a continuous channel 15, referencing Fig 39, that extends along the entire periphery of the inner frame. In some forms, the U channel 6 depth has a width we substantially the same as W, referencing Fig 34, in some forms, referencing Fig 5, 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 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; they 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.

Other particular forms of inner frame members, referencing Fig 7 to 10, have a slotted aperture 26 that extends from a mouth 27 located relative to the inner edge of the inner frame, the slotted aperture 26 being defined in-part by a fin 28 and an edge wall 29 of the inner frame. It should be appreciated that the edge wall 29, mouth 27, slotted aperture 26 are features that may extend for the entire periphery of the inner frame while the fin 28 and edge wall 29 in particular forms lie in parallel planes and in a plane parallel to the plane of the infill. The inner frame members 13 are connected by corner joints, referencing Fig 8,9 that may comprise mortise joints that in some forms include a joining member 30 having legs 31 that occupy the longitudinal recesses 32 within the abutting inner frame members, these legs 31 extending internally alongside the edge wall 33 and the adjacent walls of the inner frame and in some forms comprising an interference fit. A convenient form of inner frame, has a slotted aperture of 3 MM wide, an inner wall 34 having a depth of 16 MM (to be compatible with overlapping bars having a depth of 8 MM) connected to an angled wall 35 and other convenient dimensions.

In one form, the infill 2 is configured to include bars 36 that in some forms are configured as a substantially rectangular hollow tube 41 having a continuous axiai recess 42. Each end of each vertical bar is adapted to occupy/mate with opposed apertures 44 disposed towards the interior side of the inner edge 34 and each end of each horizontal bar is adapted to occupy/mate with opposed apertures 43 disposed towards the exterior side of the inner wall 34 [more generally, one set of bars (parallel or not) is exteriorly disposed and another set of bars (parallel or not) is interiorly disposed and each end of each bar extends through a suitable aperture in the wall of an inner frame member 24. In a particular form, each bar has cross-sectional dimensions width=13 x depth= 8 mm and a wall thickness 1.0 mm, and the bar may include an axially elongated cylindrical portion through which an axial recess 42 extends to receive the fastener 37 described below. The end of at least one bar in some forms, is connected by a fastener 37 that extends through an aperture 38 in the inner wall 39 of the inner frame to occupy an elongated axiai aperture 40 located relative to the end of the bar; in some forms each end of each bar is connected in a similar manner.

This arrangement is particularly suitable where the infill and inner frame are of similar metal and where galvanic corrosion is not an issue.

The inner frame members 24 described immediately are configured to enable a removable mesh portion (configured as a sub-assembly) to be easily attached and removed and replaced. This infilling material 45, referencing Fig 10 and 13, is configured to include an elongated upper and lower peripheral infilling frame 45, 47 about which the infilling material is partly wrapped (for better adhesion) and to which the infilling materia! is attached. In some forms, the frames 46 and 47 include a stitching channel 48 through which stitching or staples pass, the stitching or staples being applied externally to pass through the infilling material 45, then through the infilling frames 46 and 47 then through the infilling material 45 on the other side. The upper infilling frame 46 with infilling material 45 attached is received into the slotted aperture 26 within the upper inner frame member and the lower infilling frame 47 with infilling material 45 attached is received into the slotted aperture 26 within the lower inner frame member; the edges of the infilling material 45, which in some forms are partly framed and in some forms not framed, extend into the side slotted apertures 26. The combined thickness of the infilling frame 46 with infilling material 45 attached is substantially the same as the depth of the slotted apertures 26 so once inserted the teeth 49 on the walls of the slotted apertures 26 act to retain the framed end of the infill within the respective slotted apertures 26. In some forms, a screw or other fastener 66 is driven orthogonally through fin 28 to engage with infilling frame 46, 47. By this means, an alternative infill is provided that can be removed and replaced and substantially without the use of tools.

CENTRALIZING/POSITIONING THE INFILL & TYPE- 3,4 ORTHOGONAL. BLOCKS In some structures, it is important that the infili 2 be centrally located relative to the outer frame or otherwise relatively aligned to suit a particular situation or need. In some structures this is achieved by means including those described in the Patent Specifications included by reference where one such means includes an orthogonal block that may take one of two forms: a Type-3 block 50, referencing Fig 14, having a substantially cylindrical joint boss 51 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 coaxially relative to an aperture 52. The joint boss 61 includes an axially elongated threaded aperture 53 that supports a threaded fastener 54 (such as a grub screw) that is accessible through a coaxial aperture 55 disposed from the outer frame member to enable a tool (such as an Alan key) to be inserted into the fastener drive recess 56 to rotate the fastener and in some situations, to cause it to protrude from the joint boss 51 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 51 includes a substantially cylindrical end 57 of reduced diameter that extends through ah aperture 58 in the outer frame member to be outwardly peeπed over (to form a ridge 59 that overlap the outer frame member) to retain it attached to the outer frame member.

In another form of such a devise, referencing Fig 15, referred to as a Type-4 block 49, a substantially cylindrical joint boss 60 is supported in the inner edge 21 of the outer frame member 24 to extend towards the outer edge 22.The joint boss 60 includes an axially elongated threaded aperture 63 that supports a threaded fastener 64 (such as a grub screw) that is accessible through a coaxial aperture 65 in the outer frame member to enable a tool (such as an Alan key) to be inserted into the fastener drive recess 56 to rotate the fastener and in some situations, to cause it to protrude from the joint boss 61 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 60 includes a substantially cylindrical end 67 of reduced diameter that extends through an aperture 68 in the outer frame member to be outwardly peened over (to form a ridge 69 that overlap the inner surface of the inner edge 21.

KNOCK- DOWN "DlY" VERSION

Some forms of structure are further configured such that the infill is configured as multiple smaller sub-infills 70, referencing Fig 16 to 18 and some infills comprise multiple $ub-infills (that may be different but) that in some forms consist of a pair of substantially identical sub-infills, each the mirror image of the other.

In some forms, an inner frame member 71 (of the first sub-infill) and inner frame member 72 (of a second sub-infill) are adjacent and abut and in some forms they are connected by hinges 73 (having leafs 74 one connected to each inner frame member 71, 72), so that during assembly the two sub-infills simply hinge open to form a single infill. In a particular form the inner frame member 71 and 72 referencing Fig 18, 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 (described in the cross-section, referencing Fig 16) are truncated; however each has an elongated recess 32 enabling the members abutting 71 , 72 to be connected to their respective other inner frame members by joining members 30.

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 17, having a height H and width W3 the sides of the outer frame consist of a longer_outer_frame_portion 75 (that may be packed diagonally into a carton by) having a length L = sq root [(W3² +(H/2)²] and a shorter _outer_frame_portion 76 having a length = (H-L); where the identical infills have a height H/2 and a width W3. By way of example, consider a structure comprising a door having a height H=2000 MM and a width W3=800 MM, each longer_outer_frame_portion 75 is configured to have a length L = [sq root (1000²+ 800²)] ~ 1.33 M and shorter outer_frame_portion 76 has a length (2000- 1330) - 0.7 M; these outer frame members clearly fitting within a carton that will fit with a sedan vehicle. The outer frame portions 75, 76 may be connected by any convenient means including an elongated joining member 77 that extends longitudinally within the hollow 19 of each outer frame portions 75, 76 to mate with interference so as to form a rigid joint.

SlMPLE LINEAR JOINT

The outer frame portions 75, 76 may be connected by any convenient means including an elongated joining member 77 that extends longitudinally within the hotlow 19 of each outer frame portions 75, 76 to mate with only working clearances having exterior dimensions (at least in-part) that are substantially the same as the interior dimensions of the outer frame members but lesser by a working clearance.

In some forms, the joining member 77 has a first aperture 301 to receive a first fastener 302 and trie outer wall 22 of the longer_outerjrarne_portion 75 has coaxial aperture 303 enabling passage of the first fastener 302; in some forms aperture 303 is longitudinally elongated; in some forms the fastener has a pan head that seats within the channel 16 of the longer_outer_frame_portion 75; joining member 77 similarly has a second aperture 306 to receive a second fastener 307 and the outer wall 22 of the shorter __outer_frame_portion 76 has coaxial aperture 308 enabling passage of a second fastener 307; similarly aperture 306 may be longitudinally elongated; the fastener may have a pan head.

Joining members may be manufactured from any suitable material and by any suitable process; it may 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 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 can be simply adapted to provide an adjustable simple linear joint 312 enabling the effective lengths of an outer frame member that includes this construction can be increased from a minimum where portions 75 and 76 abut to a longer length where there is a gap between portions 75 and 76. Where it is intended the joint be adjustable, for each joint a horse shoe shaped side cover 304 is provided to occupying the gap and to straddle the exposed end joining member 77 plug; it will be appreciated that once the structure has been adjusted, the side cover is. cut to length (by the removal of portions 311 to suit the length of the gap. In some forms, the side cover 304 includes spaced arms 305 that extend from each end of side cover 304 configured to occupy a respective portion of channel 16, in which case fasteners 302 and 307 have a countersunk heads to seat with respective countersunk recesses 310 in a respective wing 305.

A side cover 304 can also be used to fill the gap adjacent to the corner of a butt joint (described below), in which case, the wing 305 not within the channel 16 is removed.

SIMPLE ADJUSTABLE BUTT CORNER JOINT

The outer frame members may include butt or mortise joints as described in the Patent Specifications included by reference or simple adjustable butt joints that may be configured to be "perfect " where the included angle at which the members abut is the same as the nominal angle at which the first end 81 is disposed to the axis of the first member 82 and it abuts the second member 84 at all points along an end 81. In orthogonal joints, the first end 81 may be orthogonal (as it is in the simple butt joint) or it may be substantially orthogonal but adapted (relative to a side view) to have two angled edges 86, referencing Fig 4, (equally angled relative to the longitudinal axis) that meet in the middle such that when the included angle is at either predetermined extreme disposition, one or other of the angled edge 86 is substantially parallel to the second outer frame member 84.

In some forms, the simple adjustable butt joints 8O₁ referencing Fig 19 to 20 and 4, the outer frame members 11 are connected such that an end 81 of a first outer frame member 82 is joined to (with reference to an edge portion 83 of) a second outer frame member 84 that includes a longitudinally elongated slotted edge aperture 87 in the inside edge 21 relative to which the first outer frame member is restrained.

In one form, the slotted edge aperture 87 commences at or adjacent to an open end 85 of the second outer frame member 84 and in some forms, an orthogonal rectangular slotted auxiliary aperture 88 intersects the slotted edge aperture 87 to extend sideways from aperture 87 to provide bearing surfaces 116.

In these and other forms, the end plug 92 has a protruding shoulder 94 that includes a leading end 110 defined by a radius "R" about the axis 111 that may comprise a curved convex leading end surface 112 defined by constant radius "R" defined about the axis 1 "j 1. In a. particular form, the leading end surface 112 comprises two spaced shoulders 113. In some forms, the end plug member 92 includes a pair of side bearing shoulders 115 that locate within, to be supported by the auxiliary aperture 88.

In some form, a second outer frame member 84 is characterized by concave surface 104 defined by a constant radius "R; in some forms the concave surface 104 is witfiin a member 102 supported and fixed relative to second outer frame member 84 (that may comprise a moulding and in a particular form comprises an injection moulding 515). In some forms this: member 104 has an aperture 106 about which ft is supported and through which the fastener 13 extends (with no or minima} clearance) to engage with a nut 96 described below; in some forms concave surface 104 is comprised of spaced portions. The end plug 92, is intersected by a longitudinally elongated axial aperture 120 configured to receive a fastener 13 that extends through the aperture 120 to engage with a nut 96 supported against a nut radial surface 97 on the inner end of the end plug 92 and having its surface defined by a radius "R" about an axis coaxial with axis 111; the fastener 13 also extends through the outer wall 22 of the outer frame member (with no or minimal clearance) and the head of the fastener 86 is configured as a pan or other similar head to seat within walls 14 and on the floor of the channel 16. The features are configured such that when the fastener is tightened the end plug member 92 is urged towards concave surface 104 to become restrained against relative angular displacement. Correspondingly, when included, the bearing shoulders 115 occupying the bearing recesses 116 act on the sides of the bearing recesses 116 to further resist relative angular displacement; (the bearing shoulders fitting between the sides of the bearing recesses 116 with no or only working clearance).

The butt joint is further configured to accommodate limited relative angular displacement between the end plug member 92 and concave surface 104 by accommodating rotation of the end plug member 92 about the fastener 13 by enlarging the aperture 120 such that as it extends away from the axis 111, the aperture widens; it does so in both directions relative to the axis 111. By noting that surface 97 is also radial to the axis 111, we can see that the distance between the fastener head 86 and nut 96 is substantially independent of the included angle, so that tightening the nut does not give rise to a moment urging the first and second plugs to relatively rotate. In a particular form, the nut 96 has radial inner surface 119 defined by a radius identical to radius defining surface 97 and a width such as to restrict the nut against rotation within recess 19. This butt joint, enables the included angle "alpha", to be varied without affecting the structural integrity of the corner joint (including "without significantly affecting its ability to sustain a moment")

In some structures the end plug 92 extends longitudinally into the first outer frame member 82 to become firmly fixed by means including interference; in some forms, the end plug 92 is bounded by a narrow peripheral shoulder 95 against which end 81 may abut. SIMPLE CORNER LINEAR JOINT

In some forms, referencing Fig 6 and 19, the end plug 92 mates with working clearance so that although it cannot rotate it can displace relatively acting as a simple corner linear joint 313 whereby to achieve a desired "effective length" of the first outer frame member 82 (and in doing so, a gap is left between the outer frame end 81 and surface 83); [the end plug 92 having exterior dimensions (at least in-part) that are substantially the same as the interior dimensions of outer frame member 82 but lesser by only working clearances]

In some forms, once adjusted, a fastener 38 is driven through an aperture 99 in the outer frame member to form and/or enter an aperture 79 in the end plug 92. In some forms, aperture 99 is configured as a longitudinally elongated slotted aperture enabling the first outer frame member 82 to be displaceable from the corner after the fastener 98 has been installed (but before it is tightened).

The gap referred to above, for aesthetic reasons in some structures is occupied by a horse-shoe shaped side cover 304 (described above) fitted to straddle the exposed end plug 92 by extending between the inner frame walls 5 along the end plug 92 from end 81; it will be appreciated that once the structure has been adjusted, the covers 304 may be cut to length to suit the length of the gap.

ENHANCED ADJUSTABLE BUTT CORNER JOINT - for greater resistance to moments

In a particular construction, the corner connector includes of a longitudinally elongated hollow member 91 that in one forms is free to slide with only working clearance wfthin the hollow 19 of the first outer frame member 82 (that may comprise an aluminium extrusion) and that is attached firmly (by means that may include an interference fit) to an adapted member 92.

In a particular construction, referencing Fig 21, the corner joint includes a longitudinally elongated hollow member 101 (that may comprise an aluminium extrusion) having sides 116 between which an adapted member 102 is supported, this member 101 and member 102 having coaxial apertures through which the fastener 13 extends and shoulder 94 is configured to have a depth enabling it to slide freely between the sides 116 and within a slotted aperture 103 that is aligned with aperture 87. In this case, the head of the fastener 86 may seat within a corresponding recess 107 in the outer edge of member 101. The sides 116 in some forms include notches aligned with auxiliary aperture 88 to provide auxiliary bearing recesses 105; these configured such that when the shoulder 110 is abutting surface 104, the bearing shoulders 115 are restrained within the auxiliary bearing recesses 106 but without acting to urge the bearing shoulders 110 away from the concave surface 104,

In another particular construction, referencing Fig 22, aperture 87 is omitted and the member 101 extends into outer frame member 84 to be retained there with working clearance to enable the outer frame member 84 to be displaced away from member 102 to achieve an increased "effective length" of outer frame member 84 and in doing so, a gap is left between outer frame end 89 and the end of the respective hollow member 101 and in some structures, the exposed hollow member 101 is covered by a corner cover 130 described below.

Similarly as described above, once set, a fastener 320 can be driven through an aperture 321 in the outer frame member 84 to form and/or enter an aperture 32 in the member 101. In other forms, the aperture is configured as a longitudinally elongated slotted aperture enabling the second outer frame member 84 to be displaceable from the corner after the fastener 320 has been installed (but before it is tightened)

These butt joints described immediately enable the included angle to be changed by similarly accommodating limited relative angular displacement between the end plug 92 and concave surface 104 by accommodating rotation of the end plug member 92 about the fastener 13.

The corner cover 130 referred to above and referencing Fig 5, 23 and 24, comprise a substantially rectangular shaped member that can straddle the exposed portions of the members 91 and 101 to extend between the outer frame walls 5 of the outer frame members 82 and 84 respectively from end 81 and end 89 to occupy the entire gap. Because the outer frame members may change in length, each cover needs to be adjustable in length in two orthogonal directions. In a particular form, referencing Fig 24, corresponding to the outer frame having a channel 16, the corner cover 130 includes a first arm 132 as deep and wide as channel 16 and a similar second arm 133 orthogonally disposed. From both sides of these arms there are substantially parallel substantially planar sides 134 that extend to abut. The inner surface of these sides 134 are separated by substantially the same distance as the outer surfaces of sides 18 are separated and the outer surfaces of these sides 134 are separated by substantially the same distance as the width of channel 6. After adjusting the length of an outer frame member, the corresponding side^'s 134 are cut to suitable lengths by removing side portions 135 so that after assembly they will abut the ends of the associated outer frame members.

LOCKS. HINGES & ROLLERS

Where a structure, takes the form of a hinged or sliding door, referencing Fig 29 to 30, the outer frame member corresponding to the closing edge will usually be adapted to support a lock 160; in some forms (and in particular, when the lock is a conventional Australian security door lock) this comprises making an aperture 161 in the outer edge of the outer frame to enable a lock body 162 to be inserted into the outer frame to in-part occupy recess 19 and making apertures 163 in the opposed sides to enable a cylinder 164 to be attached to the lock body and to extend through the sides of the outer frame to enable a drive rod 165 and handle back plate fixing spigots 166 to extend through the sides of the outer frame; in 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). It will be appreciated, that because the lock is fixed to the outer frame, it will displace together with the inner frame as the inner frame is displaced relatively to the outer frame during adjustment (if the lock is fitted at that time). 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 5 and in some cases, to protrude an equal distance from their associated channels 5 up to a pre-determined convenient distance.

Being able to invert the wing, requires the outer frame to have enlarged aperture/s 167 that enable the cylinder, spigots and drive rod 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 lock comprises a substantially conventional Australian security door lock (or a similar lock) the lock has upper and lower fixing tabs 168 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. 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 169. Alternatively, referencing Figs 25 to 27, 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 structure discussed above within the ranges determined by the need for the wing to have outer dimensions: height = H to H+h and width = V to V+ v. Where the structure configured as a sliding door, referencing Fig 30, the outer frame member corresponding to the lower edge of the structure will usually be adapted to support a roller 170 and may comprise making spaced elongated apertures 171 to enable the roller assemblies to be inserted into the outer frame. Where the structure configured as a hinged door, the outer frame member opposed to the closing edge will usually be adapted to support spaced hinges 172 that may comprise making spaced apertures to enable hinge the fixing screws to be attached.

ALERNATlVE INNER FRAMES & INFILLS

Particular forms of inner frame include inner frame members having a cross- sectional profile, referencing Fig 34 and 38, including a side recess 180 adjacent to a fixing shoulder 181 of an inwardly extending first fin 182 that in-part defines a slotted aperture 133 of the inner frame member that extends inwardly from a mouth 84, the slotted aperture being further defined in-part by an opposed inwardly extending second fin 185, It should be appreciated that the side recess 180, fixing shoulder 181 and first and second fins 185, 182 are features that may extend for the entire peripheral length of the inner frame while the fins in a particular form lie in parallel planes and in a plane parallel to the plane of the infill. The inner frame members 24 of this particular forms of inner frame are connected by corner joints that may comprise mortise joints, referencing Fig 35, that in some forms include a joining member 30 having legs 31 that occupy the longitudinal recesses 186 within the abutting inner frame members, referencing Fig 34, in some forms these legs 31 extending longitudinally alongside the first fin 182 and outer wall 187 of the inner frame. The joining member close to the corner of the inner frame, may also occupy the recess that extends within the rear of the slotted aperture 183 - it will be appreciated that where the recess is so occupied, the return portion 190 described below may need to be omitted or accommodated. These joining members may take any suitable inform that may comprise castings or metal pressings. In some infill the inner frame has a distance between fins of 8 MM, a side recess having a width substantially 4 MM and a slotted aperture width of 16 MM. Where the inner frame comprises extruded plastic such as pvc, the corners may be alternatively or additional joined by welding as is well known.

In some forms of inner frames, referencing Fig 34, the opposed inner surfaces of the sides 5 are inclined inwardly frorh the base 10, in some forms the opposed inner surfaces of the sides 5 are inclined inwardly from the base 10 so that the sides 5 have to be separated by force to accept the outer frame members 11 a result of which, the sides 5 press inwardly on the outer frame 3 and the frames may be further configured to ensure that the inner frame 9 is in contact with the outer frame 3 along its periphery and the frames may be configured to preclude openings between the frames through which insects, breeze or water may pass and into which tools may be inserted during forced entry. The above configuration having particular relevance to addressing the issue of requiring the sides 5 to abut both sides of the outer frame 3 even though the inner and outer frame have depths that vary within a manufacturing tolerance. In some forms, the . outer edges of the sides 5 have slightly inwardly protruding shoulders 190 that extend along the entire periphery so that the sides 5 only abut the outer frame 3 along the shoulders 190. In some forms, the opposed shoulders 190 include a gasket 191 to interface wrth the outer frame 3, the gasket providing a better seal and/or reduced friction enabling the outer frame 3 and inner frame 9 to relatively displace at reduced forces as occurs during adjustment at fitting. In some forms, the opposed shoulders 3 include a longitudinally elongated recess 192, referencing Fig 34, to receive and retain a gasket comprising an elongated resilient sealing member 193 that may comprise a rubber or plastic cord or fibrous strip; the recess 192 being characterized by a width w1 and an opening 194 of reduced width w2.

Some structures include an infill as described in the Patent Specifications included herein by reference; others include an infill as described above referencing Fig 7 to 13. Other forms of infill 2, referencing Fig 34 and 38 eiectively include an infilling material 200 that is connected to the inner frame 9 by a protruding return portion 190 {that although not limited to, may take the form of a continuous portion or multiple discrete interrupted portions) that extends sideways along the edge of the infilling material 200 to occupy side recess 180. In application, each edge of the infilling material 200 is inserted into the slotted aperture 183 through the mouth 184 of a respective frame member and subsequently, opposed inner frame members are displaced towards each other to cause the return portion 190 to occupy the side recess 180 and to overlap the fixing shoulder 181. At which time, a fixing wedge 201 (that in some forms Js a resilient and efasticaHy deformable member) is driven through the mouth 184 alongside the infilling material 200 adjacent to the second fin 185 to urge it further into the side recess 180 to prevent the return portion 190 from displacing from the recess to disengage the fixing shoulder 180. It will be appreciated that the mouth and slotted aperture need to be wide enough to provide passage for the return portion 190; 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 203 of the second fin 185 may be textured and it may be ramped 204, referencing Fig 36, (to better retain the fixing wedge 201 and/or strip described below); the ramping on the second fin including inclined surfaces 206 that extend inwardly as they extend away from the fin mouth and the fixing wedge may include a mating ramped surface 212 that extend outwardly as they extend inwardly - the components preferably being configured such that as the fixing wedge is driven in, high, ridges on the fixing wedge displace over the high ridges of the second channel. When installed the high ridges engage to retain the fixing wedge within the slotted aperture 183. 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. A convenient infill consistent with the- inner frame described above has a slotted aperture 8 MM deep has a thickness substantially 1.0 MM, a return of 5.5 MM (6 MM less a working clearance 0.5 MM) and the strip 62 described below of insulating material has a depth 1.00 MM while the fixing wedge 53 would have a depth substantially 6 MM. in some infills, referencing Fig 36. a strip 207 of materia? (that in some forms is a resilient and elastically deformable member) extends the length of the slotted aperture 183 between the first fin 182 and infilling material 200. In some forms it includes a return 208 that extends sideways to overlap the fixing shoulder 181, to separate the return portion 190 from fin 182. In some forms, the strip 207 is a resilient and/or elastically deformable member that deforms to protrude into the surface of the infilling material while in other forms having a contoured surface that protrudes into the surface of the infilling material so that in either case, installation of the fixing wedge 201 urges the infilling material against the strip 207 both to retain the retain the surface of the strip 207 protruding into the infilling material 200 to retain the infilling material relative to the fixing shoulder 181. This latter form is particularly relevent to infills not having a return portion 208 and having a textured or profiled surface and is particularly well suited to woven metal mesh and the strip may take the form of a nylon strip having a surface that mates with a side of the woven mesh.

Some such forms may include a similar opposed strip that extends the length of the slotted aperture 183 between the fixing wedge 201 and infilling material 200 that in some forms has a return {hat extends sideways to overlap the leading end of the fixing wedge 201 (of reduce depth) The above means are particularly relevant to the retention of infilling material taking the form of woven mesh, and the strip may take the form of a nyion strip having a surface that mates with a side of the woven mesh. in some forms, the strips may be configured to act as an insulating material and be constructed from a material such as nylon to reduce the probability of galvanic corrosion, this being particularly relevant where the infilling material and inner frame are constructed from different metals; the fixing wedge may similarly be constructed from insulating materia! such as nylon and for the same reason.

The infill may include other material, referencing Fig 38, such as 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 while holding it separate from the inner frame. The infill 2 may be configured to include bars 220, referencing Fig 30 to 32, each end of each bar 220 connected by a fastener 221 that extends through an apertures 223 of the inner frame to occupy an elongated axial aperture 222 located relative to the end of the bar. In some structures, each bar is configured as hollow tube 224 having a continuous axial recess 225. Each end of each bar is adapted to occupy the slotted aperture 183 by having an elongated end portion 226 having a width Jess than that of the slotted aperture 183 and a depth substantially the same as that of the slotted aperture 183. In some forms, each end portion 226 is enveloped by a mating boot 227 having an inner surface that substantially conforms to the outer form of the end portion 226 and having an outer surface that mates within the slotted aperture 183 and it extends to abut the inner wall 228 of the slotted aperture. In a particular configuration, within each tube end is a threaded tube insert 229. In a particular form, the bar has cross-sectionai dimensions 13 x 13 mm and a wall thickness 1.0 mm, the slotted aperture 183 has a depth 8 mm, the end portion within supports a tube insert 229 having a portion 11 x 11 MM and a portion 11 x 6 MM through which an axial recess 230 extends to receive a fastener 221 and the boot 227 has a wall thickness of 1.0 mm. This arrangement enables an infill of a dissimilar metal to be attached to the inner frame without directly contacting it thus reducing the probability of galvanic corrosion. It should be understood that the bars in some forms are further configured, referencing Fig 31, 32 (remote from the slotted aperture 183) so that some may extend adjacently (one set horizontally the other vertically) to form a secure grill and yet still be attached as described above. The bar form shown in Fig 31, 32 is suitably offset enabling a similar horizontal bar (rotated about its axis 180 degrees with reference to the bar 220 shown in Fig 31) to extend past bar 220 without intersecting it. Some infills, referencing Fig 33, have an inner frame adapted to provide an infill ' that includes a removeable infill portion 239 configured as a sub-assembly that may easily be removed - and to be replaced if damaged, for example by one in good condition. This removeable infill portion 239 in one form, is configured to have a peripheral infilling frame 241 configured to be attached to a side of the inner frame. In, a particular form, the infilling frame has a resilient outer leaf 243 and an opposed inner edge peripheral blade 244. The inner frame has a peripheral undercut recess formed by an overlapping shoulder 250 that overlaps the leaf to require the leaf to deform to leave the recess 249. The above features are further configured such that in usage, the blade 244 would be inserted into a corresponding undercut recess 247 and the leaf 243 would be pushed inwardly to slide down the ramped shoulder become overlapped by the overhanging shoulder 250. Similarly, other sides of the infilling frame would be attached to corresponding inner frame members. In some form, the infilling material 81 is configured as flexible mesh 251 that may comprise fiberglass mesh and the infilling frame 32 is configured as mating strips 93 between which the infilling material 241 is sandwiched; in some forms, which the infilling frame is fabricated by uitrasonicalty welding nylon together with the fiberglass mesh between, in other forms, a raised undercut axially elongated protrusion of a cover strip is forced into a mating under cut aperture in the underlying strip with the mesh 252 sandwiched between to be retained there by dint of the undercut features. By this means, an infill is provided that can be removed and replaced and substantially without the use of tools
