Description of Embodiments

[0033] Referring firstly to FIGs. 1 and 2 of the accompanying drawings, there is depicted a frame assembly 100 for retaining a security screen 102. In a preferred embodiment, the frame assembly 100 is assembled with the security screen 102 to provide a security door 104. The security screen 102 is preferably formed of a perforated stainless steel sheet or mesh, but may alternatively be made of aluminium, other metal alloys, synthetic fibre, fibreglass or other composite materials. In other embodiments, the frame assembly 100 may be assembled with other types of screens or panels and may be utilised in the construction of sliding doors, hinged doors, pivot doors and other forms of doors. The described embodiments are equally applicable to windows and other structures which require an opening to be covered.

[0034] The frame assembly 100 includes a frame 106 to be fixed to a supporting structure (not shown). The frame 106 surrounds an opening 108 to be closed by the screen 102. The frame is of a generally square or rectangular configuration so as to provide a plurality of elongate frame members, that is, a pair of opposing vertical stiles 110, 112 and a pair of opposing horizontal rails 114, 116 extending between the stiles 110, 112. The stiles 110, 112 and the rails 114, 116 are preferably formed from extruded sections of aluminium.

[0035] With particular reference to FIGs. 3 and 4, the rails 114, 116 include a generally horizontal and longitudinally extending base 118 providing a longitudinal central axis 120 (shown in FIG. 1). The base 118 has a width extending transversely with respect to the axis 120 between a pair of side portions 122a, 122b. Each of the rails 114, 116 has a plane of symmetry A coincident with the axis 120. Similarly, the stiles 110, 112 include a generally vertical and longitudinally extending base 124 providing a longitudinal central axis 126 (shown in FIG. 2) extending perpendicularly with respect to the axis of the rails 120. The base 124 has a width extending transversely with respect to the axis 126 between a pair of side portions 128a, 128b. Each of the stiles 110, 112 has a plane of symmetry B (see Fig. 4) coincident with the axis 126. The planes of symmetry A, B are generally co-planar. Skilled workers in this filed will understand the stile 112 is a so-called 'meeting stile' (it moves to meet with another stile). As such, meeting stiles include a longitudinally extending dust seal fin 129 projecting generally parallel with the plane of symmetry B adjacent the side portion 128b, and hence the extrusion is not strictly symmetrical, but still symmetrical in terms of the main extrusion that receives the inserts and the screen.

[0036] Extending generally vertically from a respective one of the side portions 122a, 122b of the base 118 of each of the rails 114, 116 is a longitudinally extending first flange 130 and a longitudinally extending second flange 132. The second flange 132 opposes the first flange 130 with respect to the plane of symmetry A. The second flange 132 is spaced from the first flange 130 so as to define a longitudinally extending cavity or channel 134 between the first and second flanges 130, 132. The flanges 130, 132 terminate to form an edge portion 136 (shown in FIG 3).

[0037] The flanges 130, 132 have a transverse cross-section that is generally wedge-shaped so as to provide an inner surface 138 adjacent the channel 134 that is inclined with respect to the plane of symmetry A, and an outer surface 140 to face an interior or exterior with respect to the opening 108. The inner surface 138 is inclined so that a transverse width of the channel 134 tapers in a direction toward the base 118. In other words, the width of the channel 134 is greater between the edge portions 136 of the flanges 130, 132 than adjacent the base 118.

[0038] Similarly, extending generally horizontally from a respective one of the side portions 128a, 128b of the base 124 of each of the stiles 110, 112 is a longitudinally extending third flange 142 and a longitudinally extending fourth flange 144. The fourth flange 144 is spaced from the third flange 142 so as to define a longitudinally extending cavity or channel 146 between the third and fourth flanges 142, 144. The flanges 142, 144 terminate to form an edge portion 148.

[0039] The flanges 142, 144 have an abutment portion 150 adjacent each of the edge portions 148. Each of the abutment portions 150 provide an inner surface 152 adjacent the channel 146 that is inclined with respect to the plane of symmetry B. The inner surface 152 is inclined so that a transverse width of the channel 146 between the abutment portions 150 tapers in a direction toward the base 124. The flanges 142, 144 also provide an outer surface 154 to face an interior or exterior with respect to the opening 108.

[0040] Each of the stiles 110, 112 and each of the rails 114, 116 further include a pair of longitudinally extending clip members 156 projecting perpendicularly from a respective one of the bases 118, 124 into a respective one of the channels 134, 146 and terminating to form a free hanging end portion 158. Each of the clip members 156 include a resiliently deformable stem 160 connecting the free-hanging end portion 158 to the respective base 118, 124. The stems 160 of the clip members 156 are spaced from and oppose each other with respect to a respective one of the planes of symmetry A, B. The stems 160 are equally spaced from a respective one of the flanges 130, 132, 142, 144. The free-hanging end portion 158 includes a longitudinally extending ledge surface 162 projecting laterally from the stem 160 in a direction away from a respective one of adjacent flanges 130, 132, 142, 144. The ledge surface 162 terminates to form a ledge edge 164. The free-hanging end portion 158 further includes a longitudinally extending guide surface 166 projecting from the ledge edge 164. The guide surface 166 is inclined by an acute angle to the ledge surface 162.

[0041] Each of the rails 114, 116 further include a pair of longitudinally extending locating tabs 168 projecting perpendicularly from the base 118 into the channel 134. The tabs 168 project to a depth which is less than a depth to which the clip members 156 project into the channel 134. The tabs 168 include a first sidewall 170 spaced from the stem 160 of the respective clip member 156. Together, the sidewall 170, the stem 160 and the base 118 define a longitudinally extending slot 172 within the channel 134. The tabs 168 include a second sidewall 174 opposite the first sidewall 170. The tabs 168 further include a seating surface 176 adjacent the base 118 that projects laterally from the second sidewall 174 towards the plane of symmetry A. The second sidewall 174 is inclined by an obtuse angle to the seating surface 176.

[0042] Similarly, the stiles 110, 112 further include a pair of longitudinally extending tabs 178 projecting perpendicularly from the base 124 into the channel 146. The tabs 178 project to a depth which is less than a depth to which the clip members 156 project into the channel 146. The tabs 178 include a third sidewall 180 spaced from the stem 160 of the respective clip member 156. Together, the sidewall 180, the stem 160 and the base 124 define a longitudinally extending slot 182 within the channel 146. The tabs 178 include a fourth sidewall 184 opposite the third sidewall 180. Unlike the tabs 168 of the rails 114, 116, the tabs 178 of the stiles 110, 112 do not include a seating surface.

[0043] The base 118, 124, the flanges 130, 132, 142, 144, the clip members 156 and the tabs 168, 178 of each of the rails 114, 116 and the stiles 110, 112 are preferably co-extruded so as to be integrally formed.

[0044] With particular reference to FIGs. 5 and 6, the frame assembly 100 further includes a pair of first and second beads or inserts 186, 188 to be arranged partly within the channel 134 of the rails 114, 116 and the channel 146 of the stiles 110, 112. The inserts 186, 188 include a longitudinally extending planar body 190. The body 190 has a transverse width extending between first and second side portions 192, 194 of the body 190. The width of the body 190 is generally equal to or less than half the width of the base 118, 124 of the respective rail 114, 116 or stile 110, 112.

[0045] Projecting from the body 190 of the first insert 186 are longitudinally extending first and second leg portions 196, 198 adjacent the respective first and second side portion 192, 194. The leg portions 196, 198 are preferably integrally formed with the body 190. The first leg portion 196 is spaced from an edge of the side portion 192 to form an overhang 200. The overhang 200 is configured to rest on the edge portion 136 of the flange 130 or on the abutment portion 150 when the insert 186 is arranged within the channels 134, 146 as will be explained in greater detail below. The first leg portion 196 of the first insert 186 has a mating surface 202 that is inclined by an obtuse angle to the overhang 200 for ramped engagement with a respective one of the inner surfaces 138, 152 of the flange 130 or the abutment portion 150. In this way, the mating surface 202 is inclined to the plane of the opening 108 for flat contacting engagement with a respective one of the surfaces 138, 152 of the flange 130 or the abutment portion 150.

[0046] The second leg portion 198 of the first insert 186 is spaced from the first leg portion 196 and projects generally perpendicularly from the body 190. Projecting laterally from a lower portion of the second leg portion 198 is a longitudinally extending shelf 202 to engage the ledge surface 162 of the clip member 156. The second leg portion 198 further includes a tapered foot 206 to engage the seating surface 176 and the second sidewall 174. The second leg portion 198 of the first insert 186 also includes a secondary foot 208 extending from the shelf 202 to be received within the slot 172, 182.

[0047] The second leg portion 198 includes a gripping profile 210 extending the longitudinal length of the second leg portion 198. The gripping profile 210 faces outwardly with respect to the insert 186. In a preferred embodiment, the gripping profile 210 is provided by channeling grooves 212 along the longitudinal length of the second leg portion 198 to form a plurality of longitudinally extending ribs 214.

[0048] Like the first insert 186, the second insert 188 includes longitudinally extending third and fourth leg portions 216, 218 projecting from the body 190 adjacent the respective first and second side portions 192, 194 of the second insert 188. The leg portions 216, 218 are preferably integrally formed with the body 190. The third leg portion 216 is spaced from an edge of the side portion 192 to form an overhang 220. The overhang 220 is configured to rest on the edge portion 136 of the flange 132 or on the abutment portion 150 when the insert 188 is arranged within the channels 134, 146 as will be explained in greater detail below.

[0049] The third leg portion 216 has a mating surface 222 that is generally perpendicular to the overhang 220 for engagement with the respective inner surfaces 138, 152 of the flange 132 or the abutment portion 150. Projecting from the mating surface 222 is a ramp 224 that is inclined by an acute angle to the mating surface 222. The ramp 224 leads to a foot 226 of the third leg portion 216.

[0050] The fourth leg portion 218 of the second insert 188 is spaced from the third leg portion 216 and projects generally perpendicularly from the body 190. Projecting laterally from a lower portion of the fourth leg portion 218 is a longitudinally extending shelf 228 to engage the ledge surface 162 of the clip member 156. The fourth leg portion 218 further includes a tapered foot 230 to engage the seating surface 176 and the second sidewall 174. Unlike the second leg portion 198 of the first insert 186, the fourth leg portion 218 of the second insert 188 does not include a secondary foot to be received within a slot.

[0051] Like the second leg portion 198, the fourth leg portion 218 includes the gripping profile 210 extending the longitudinal length of the fourth leg portion 218. The gripping profile 210 faces outwardly with respect to the insert 188. In a preferred embodiment, the gripping profile 210 of the fourth leg portion 218 includes the grooves 212 and the ribs 214.

[0052] A method 250 of assembling the security door 104 will now be described with reference to FIGs. 7a to 7d. The method 250 includes an initial step of providing the frame members, that is, the rails 114, 116 and the stiles 110, 112. At step 252, the first insert 186 is provided and positioned relative to the respective channel 134, 146. The first insert 186 is then moved toward the respective base 118, 124 of each of the frame members so that the secondary foot 208 engages the guide surface 166 of the clip member 156 causing the stem 160 to momentarily deform. Movement of the first insert 186 is continued until the lower portion of the second leg portion 198 clears the guide surface 166 at which point the ledge surface 162 snap-lockingly engages the shelf 204 thereby at least aiding in securing the first insert 186 to the respective frame member.

[0053] Further movement of the first insert 186 towards the respective base 118, 124 is prevented by engagement between the overhang 200 and the edge portion 136 of the flange 130 (if the frame member is one of the rails 114, 116) or the abutment portion 150 (if the frame member is one of the stiles 110, 112). In this position, the secondary foot 208 is positioned within one of the respective slots 172, 182 and the tapered foot 206 is engaged with one of the respective sidewalls 174, 184 (and the seating surface 176 if the frame member is one of the rails 114, 116) to further aid in securing the first insert 186 to the frame member.

[0054] As the first insert 186 is moved towards the respective base 118, 124, the mating surface 202 engages the inner surface 138 of the flange 130 (if the frame member is one of the rails 114, 116) or the abutment portion 150 (if the frame member is one of the stiles 110, 112) in a ramped manner. By virtue of this ramped engagement, the first insert 186 is urged in a direction away from the respective flange 130, 144.

[0055] The first insert 186 is configured to be entirely located within the channel 146 of each of the stiles 110, 112 so that the body 190 is generally co-planar with the edge portions 148 of the flanges 142, 144.

[0056] Once the first insert 186 is secured to the frame member, at step 254, the screen 102 is then positioned relative to the first insert 186 so that a respective edge portion of the screen 102 is engaged with the gripping profile 210 of the first insert 186. In this way, the screen 102 is arranged to be co-planar with the planes of symmetry A, B so that the screen 102 sits generally within a central region of the frame 106. A longitudinal clearance 232 may be formed in the base 118 of the rails 114, 116 to receive part of the edge portion of the screen 102.

[0057] At step 256, the second insert 188 is then provided and positioned relative to the respective channel 134, 146. The second insert 188 is then moved toward the respective base 118, 124 of each of the frame members so that the ramp 224 engages the guide surface 166 of the clip member 156 causing the stem 160 to momentarily deform. Movement of the second insert 188 is continued until the lower portion of the fourth leg portion 218 clears the guide surface 166 at which point the ledge surface 162 snap-lockingly engages the shelf 228 thereby at least aiding in securing the second insert 188 to the respective frame member. Further movement of the second insert 188 towards the respective base 118, 124 is prevented by engagement between the overhang 220 and the edge portion 136 of the flange 132 (if the frame member is one of the rails 114, 116) or the abutment portion 150 (if the frame member is one of the stiles 110, 112). In this position, the foot 226 is engaged with the stem 160 of the respective clip member 156 and the tapered foot 230 is engaged with the respective sidewall 174, 184 (and the seating surface 176 if the frame member is one of the rails 114, 116) to further aid in securing the second insert 188 to the frame member.

[0058] As the second insert 188 is moved towards the respective base 118, 124, the gripping profile of 210 of the second insert 188 slidably engages the edge portion of the screen 102 whilst the mating surface 222 simultaneously engages the inner surface 138 of the flange 132 (if the frame member is one of the rails 114, 116) or the abutment portion 150 (if the frame member is one of the stiles 110, 112) in a ramped manner.

[0059] As shown in step 258, by virtue of this ramped engagement, the second insert 188 is urged in a direction toward the edge portion of the screen 102 so that frictional resistance between the gripping profiles 210 and the edge portion of the screen 102 securely retains the screen 102 between the second and fourth leg portions 198, 218 which are in turn securely retained within the respective frame member.

[0060] The second insert 188 is entirely located within the channel 146 of each of the stiles 110, 112 so that the body 190 is generally co-planar with the edge portions 148 of the flanges 142, 144.

[0061] Preferably, the first insert 186 and/or the second insert 188 is assembled to the frame member with the aid of a mechanical device such as a pneumatic or hydraulic press (not shown).

[0062] Referring to FIG. 8 of the accompanying drawings, a security door 300 according to a second embodiment is depicted. In the assembly of the security door 300, the first and second inserts 186, 188 are replaced with third and fourth inserts 236, 238, respectively. The inserts 236, 238 are of a similar configuration to the inserts 186, 188, respectively, of the first embodiment. Accordingly, for features that are identical between the inserts 236, 238 and the inserts 186, 188, it will be appreciated that the above description of those features in relation to the inserts 186, 188 is also applicable to the corresponding identical features found in the inserts 236,238.
