Description

TECHNICAL FIELD

[0001] The present invention relates to a profile device for forming part of a frame member. In particular, the present invention relates to a profile device for a frame member, the frame member being suitable for forming part of a frame assembly for a glazing system. The present invention further relates to a frame member comprising the profile device, a frame assembly comprising one or more of the frame members, and a glazing system comprising the frame assembly, the glazing system being useable in a window system, door system or façade element.BACKGROUND

[0002] In the construction of windows, it is desirable to maximise thermal performance and mitigate heat loss through the window. For example, the use of double-glazed units and triple glazed units in glazing systems contributes to the reduction of heat loss through the glass of the window. These glazing systems may be suitably implemented, for example, in skylight window systems, where the glazing system is placed on and fixed to a support member, such as an upstand.

[0003] However, one potential source of heat loss from the warm internal surface of a building to outer surface of the building is via the frame assembly of the glazing system. In glazing systems where the frame assembly is made from a metallic material, such as aluminium or steel for example, whilst these materials provide substantial reductions in both weight and strength, they are effective heat conductors and accordingly, heat may therefore escape via the frame assemblies thus counteracting the insulation properties provided by the glazing unit used within the glazing system.

[0004] In order to mitigate heat loss through these types of frame assemblies, a thermal barrier, also known as a thermal break, is typically implemented in the glazing system used. The thermal break is manufactured using a material that has a low thermal conductivity, relative to the metal used for the frame assembly. The thermal break forms part of the glazing system and is used to interrupt thermal transfer via the frame assembly of the glazing system used.

[0005] However, one issue with current glazing systems is that, depending on the thickness of glazing unit required, the remaining parts of the glazing system must be manufactured to specifically accommodate that thickness of glazing unit. For example, should it be desirable to use a triple-glazed unit in a glazing system, it is necessary to manufacture at least a custom frame assembly specific to that thickness of glazing unit, and typically, a thermal break specific to accommodate that thickness of glazing unit. If another thickness of glazing unit is to be implemented, at least a separate frame assembly and typically a thermal break must be manufactured that is specific to and only useable for that thickness of glazing unit. Accordingly, the requirement to manufacture and stock many different components increases the costs associated with the manufacture of these glazing systems as well as the complexity of stocking systems. Additionally, should a user of the window system wish to upgrade from a first glazing unit to a second glazing unit with an improved thermal performance, such as from a double-glazed unit to a triple-glazed unit, it is necessary to manufacture an entirely separate glazing system having a triple-glazed unit for swapping with the currently fitted glazing system.

[0006] It is an object of the present invention to mitigate or obviate the disadvantages as outlined above.SUMMARY

[0007] According to a first aspect of the invention, there is provided a profile device for forming part of a frame member, the frame member being suitable for forming part of a frame assembly for a glazing system, the glazing system comprising a glazing unit selectable from a first glazing unit having a first glazing unit thickness and a second glazing unit having a second glazing unit thickness that is different to the first glazing unit thickness, said frame member comprising a first portion comprising a first portion profile member and a second portion comprising the profile device, wherein the profile device comprises: a profile body comprising a plurality of surfaces; wherein the plurality of surfaces comprise a first surface and a second surface opposite to and spaced apart from the first surface; wherein the first surface has a first end and a second end; wherein the second surface has a first end and second end; wherein the profile body comprises a first side that extends from the first end of the first surface to the first end of the second surface, wherein the first side is configured, in use, to be a coupling side; wherein the profile body extends in a first direction; wherein the profile body extends in a second direction, wherein the second direction is a longitudinal direction, and wherein the first direction is perpendicular to the longitudinal direction; wherein the first surface and the second surface are spaced apart from each other in the first direction; wherein the profile body has a central plane extending through the profile body that is perpendicular relative to the first direction; wherein the coupling side comprises one or more coupling portions, wherein the, or each, coupling portion is engageable with an engaging portion located on the first portion profile member such that the profile device is couplable to the first portion profile member to form a recess for receiving a part of the glazing unit; wherein the one or more coupling portions of the coupling side comprise one or more offset coupling portions wherein the, or each, offset coupling portion is offset relative to the central plane of the profile body; wherein the profile device is configured to be couplable to the first portion profile member in a first coupling position and a second coupling position; wherein, in the first coupling position, the profile device is couplable to the first portion profile member to form a first interlocking arrangement in which the first portion profile member is fixable, relative to the profile device, in a first position along the first direction; wherein, in the second coupling position, the profile device is couplable to the same first portion profile member to form a second interlocking arrangement in which the same first portion profile member is fixable, relative to the profile device, in a second position along the first direction that is different to the first position; and wherein said profile device is switchable between the first coupling position and the second coupling position by rotation of the profile device about at least one rotational axis of the profile device.

[0008] Beneficially, the profile device of the present invention is useable to adjust the position of a corresponding profile member for forming part of a frame member in the first direction. The one or more offset coupling portions, being offset relative to the midplane of the profile body, enables the frame member formable from interlocking the profile device and corresponding first portion profile member to be useable for a pair of glazing units selectable for use in the glazing system. In contrast, other frame members are solely manufactured for a single glazing unit thickness, meaning that a glazing unit having a different thickness requires a separately designed frame member.

The central plane may extend through a midpoint of the interior space formed between the plurality of surfaces.

The profile device may be operable to control the depth of the recess formed by being selectively implementable in the first interlocking arrangement or the second interlocking arrangement. Beneficially, this enables a user or manufacturer to selectively control the recess depth formed without having to manufacture additional components to suit another glazing unit thickness.

[0161] The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

[0162] The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention.

[0163] It is to be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

[0164] Referring generally to Figures 1 and 2, there is shown a non-limiting example of a profile device, generally indicated by reference numeral 100. The profile device has a profile body 102 comprising a plurality of surfaces 104, 106, 108, 110, 112.

[0165] The profile body 102 extends in a first direction. The profile body 102 extends in a second direction, wherein the second direction is a longitudinal direction, and wherein the first direction is perpendicular to the longitudinal direction. The longitudinal direction corresponds to the longitudinal direction of the profile device 100. The profile body 102 has a central plane (CP) extending through the profile body 102 that is perpendicular relative to the first direction. It will be understood that the central plane is simply an imaginary plane that passes through the body. The first direction, as shown in the non-limiting example shown in Figures 1 and 2, is a height direction, with the profile body 102 also extending in a third direction which is a transverse direction. It will be understood however that the first direction may instead be the transverse direction, and the third direction may instead be the height direction.

[0166] The plurality of surfaces 104, 106, 108, 110, 112 comprises a first surface 104 and a second surface 106 opposite to and spaced apart from the first surface 104. The first surface 104 has a first end 114a and a second end 114b. The second surface 106 has a first end 116a and second end 116b. The first surface 104 and the second surface 106 are spaced apart from each other in the first direction.

[0167] The profile body comprises a first side 118 that extends from the first end 114a of the first surface 104 to the first end 116a of the second surface 106, wherein the first side is configured, in use, to be a coupling side 118. The coupling side 118 comprises one or more surfaces (two shown), 108, 110. As shown in the non-limiting example in Figures 1 and 2, the coupling side comprises a first surface 108 extending in the first direction and a second surface 110 inclined relative to the first direction. The first surface 108 of the coupling side 118 as shown is a coupling surface 108. By coupling surface, is meant that coupling means are located on the surface. The second surface 110 connects a first end 120 of the coupling surface 108 to the first end 114a of the first surface 104. The second surface 110 of the coupling side 118, as shown, is inclined angularly relative to the first direction. In use, the incline surface 110 is advantageous as it may enable tools, such as a rolling tools, to be used to aid assembly of a frame member of a frame assembly that comprises the profile device 100, as will be later described.

[0168] The profile body 102 also comprises a second side 122 that is spaced apart from the first side 118. The second side 122 is oppositely arranged to the first side 118 and comprises a single second side surface 112.

[0169] The profile body 102 is a tubular profile body 102. The tubular profile body 102 is defined by the plurality of surfaces 104, 106, 108, 110, 112, with the plurality of surfaces 104, 106, 108, 110, 112 being arranged to define an interior space therebetween. The central plane (CP) extends through a midpoint (MP) for a spacing distance of the profile body 102 measurable in the first direction. In particular, the midpoint (MP) is the midpoint (MP) associated with a spacing distance between the first surface 104 and the second surface 106, wherein the midpoint is equidistant from first surface 104 and the second surface 106 of the tubular profile body. The spacing distance is the maximum spacing distance between the first surface 104 and the second surface 106.

[0170] The profile device 100 is an elongate profile device 100 and has a geometric cross-section, and in particular a pentagonal cross-section. However, it will be readily understood that other geometric cross-sections may suitable be used such as quadrangular, hexagonal and octagonal cross-sections, amongst others. The geometric cross-section can be irregularly shaped or regularly shaped

[0171] The profile body 102 as shown is a hollow. The profile device 102 has one or more struts (three shown) 124 extending between surfaces of the profile device, and in particular, extending between the first surface 104 and second surface 106 of the device. The one or more struts 124 are spaced apart from one another to form a plurality of hollow channels 126 within the interior space defined by the plurality of surfaces 104, 106, 108, 110, 112. It will be understood however, that the profile device 100 does not necessarily need to be hollow.

[0172] The profile device 100 is formed from a thermally insulating material, such as polyamide. In use, this enables the profile device 100 to stop heat transfer from inside of a building to outside of a building.

[0173] The coupling side 118 comprises one or more coupling portions 128, wherein the, or each, coupling portion 128 is engageable with an engaging portion located on the first portion profile member such that the profile device 100 is couplable to the first portion profile member to form a recess for receiving a part of the glazing unit 302, as will be later described.

[0174] The one or more coupling portions 128 are homogenously formed as part of the profile body 102. In the non-limiting example shown in Figures 1 and 2, the one or more coupling portions 128 comprise two male coupling portions 128a, 128b, wherein each male coupling portion 128a, 128b is engageable with a respective female engaging portion located on the first portion profile member. It will be appreciated however, that the coupling portions 128 need not be limited to two coupling portions 128, and other variations, such as one coupling portion, or more than two coupling portions may be suitably implemented. Furthermore, whilst the two coupling portions 128a, 128b shown are male coupling portions 128a, 128b, it will be understood that that coupling portions 128 need not be restricted to being male coupling portions and may instead be, or comprise, female portions for example

[0175] The one or more coupling portions 128 of the coupling side 118 comprise one or more offset coupling portions 128 wherein the, or each, offset coupling portion 128a, 128b is offset relative to the central plane of the profile body. As shown in the non-limiting example in Figure 1 and 2, the one or more offset coupling portions comprises a plurality of offset coupling portions 128a, 128b. The plurality of offset coupling portions 128 comprises a first offset coupling portion 128a and a second offset coupling portion 128b, wherein the first offset coupling portion 128a and second offset coupling portion 128b are offset from the central plane (CP). The first offset coupling portion 128a is offset from the central plane (CP) by a first offset distance, and the second offset coupling portion 128b is offset to the central plane (CP) by a second offset distance that is non-equivalent to the first offset distance. The first offset coupling portion 128a and the second offset coupling portion 128b are asymmetrically offset from the central plane (CP).

[0176] The first offset coupling portion 128a and the second offset coupling portion 128b each comprise a coupling part 130a, 130b for engagement with the engaging portions located on the first portion profile member. Each coupling part 130a, 130b is functionable, in use, to form an interlock with the engaging portions located on the first portion profile member. Each, interlock formable lies on an interlocking plane as will be later described.

[0177] The profile device 100 is configured to be couplable to the first portion profile member 204 in a first coupling position and a second coupling position, as shown in Figures 1 and 2 respectively. In the first coupling position, the profile device 100 is couplable to the first portion profile member 204 to form a first interlocking arrangement in which the first portion profile member 204 is fixed, relative to the profile device 100, in a first position along the first direction. In the second coupling position, the profile device 100 is couplable to the same first portion profile member 204 to form a second interlocking arrangement in which the same first portion profile member 100 is fixed, relative to the profile device 100, in a second position along the first direction that is different to the first position.

[0178] The profile device 100 is switchable between the first coupling position and the second coupling position by rotation of the profile device 100 about at least one rotational axis of the profile device 100. In the embodiment shown in Figures 1 and 2, the at least one rotational axis comprises a transverse axis of the profile device 100. The profile device 100, in the first coupling position, is rotatable one hundred and eighty degrees about the transverse axis of the profile device 100 to switch to the second coupling position. The profile device 100, in the second coupling position, is rotatable one hundred and eighty degrees about the transverse axis of the profile device 100 to switch to the first coupling position.

[0179] Referring now generally to Figures 3 to 6, there is shown a non-limiting example of a window assembly, generally indicated by reference numeral 400. The window system 400 comprises a glazing system 300. The glazing system comprises a glazing unit 302, wherein the glazing unit 302 is selectable from a first glazing unit 302a having a first glazing unit thickness and a second glazing unit 302b having a second glazing unit thickness that is different to the first glazing unit thickness.

[0180] The glazing unit 302 is implementable as the first glazing unit 302a or the second glazing unit 302b within the glazing system 300. In Figures 3 and 4, the window system 400 is shown with the glazing unit 302 being implemented as the first glazing unit 302a. In Figures 5 and 6, the window system 400 is shown with the glazing unit 302 being implemented as the second glazing unit 302b. In the non-limiting example of the window system 300 shown, the first glazing unit 302a implementable in the glazing system 300 as the glazing unit 302 is a double-glazed unit 302a and the second glazing unit 302b implementable in the glazing system 300 as the glazing unit 302 is a triple-glazed unit 302b.

[0181] The triple-glazed unit 302b shown in Figures 5 and 6 has a larger thickness than the double-glazed unit 302a shown in Figures 3 and 4. For example, in the non-limiting example shown, the double-glazed unit 302a is 25 mm thick and the triple-glazed unit 302b is 32 mm thick. However, the glazing unit 302 is not restricted to being implementable using this pair of glass thicknesses, nor is it restricted to being implementable as a double-glazed unit 302a or a triple-glazed unit 302b. The glazing unit 302 could be, for example, a double-glazed unit with a first thickness as the first glazing unit and another double-glazed unit with a second thickness as the second glazing unit. Furthermore, the glazing unit 302 need not necessarily be selectable from a double-glazed unit or a triple-glazed unit and may comprise a single-glazed unit as the first glazing unit and / or second glazing unit for example. Other types of glazing units, such as quadruple glazed units, may also be suitably implemented as the glazing unit.

[0182] The glazing unit 302 may be a glass glazing unit 302. The glazing unit 302 may be a plastic glazing unit 302. The glazing unit 302 may be any suitable glazing that is implementable within the glazing system 300.

[0183] The glazing system 300 comprises a frame assembly 200 comprising one or more frame members 202 (one shown). The frame member 202 shown comprises a first portion 202a comprising the first portion profile member 204. The frame member 202 shown in Figures 3 to 6 also comprises a second portion 202b, the second portion 202b comprising the profile device 100.

[0184] The first portion profile member 200 in the example shown is formed from metal, such as aluminium. The first frame profile member 204 may also be described as a cover profile member 204. As shown in Figures 3 to 6, the first portion profile member 204 has a fixed length in the first direction. The fixed length of the first portion profile member 204 is coaxially aligned with the first direction.

[0185] The first portion profile member 204 comprises a profile member body 208. The profile member body 208 has a first surface 210a. The profile member body 208 has a second surface 210b. The first surface 210a may be arranged, in use, to be an inner surface 210a. The second surface 210b may be arranged, in use to be an outer surface 210b. By outer surface 210b, it is meant that this surface 210b may exposed to the outer surface environment of a building. For example, in the window system 400 shown, the outer surface is exposed to the outer surface environment.

[0186] The first portion profile member 204 comprises one or more engaging portions (two shown) 206 for coupling of the profile device 100 thereto. The one or more engaging portions 206 of each first portion profile member 204 are located on the first surface 210a of the first portion profile member 204. In the non-limiting example shown, the two engaging portions 206a, 206b comprise a first female engaging portion 206a and a second female engaging portion 206b.

[0187] Each engaging portion 206a, 206b is homogeneously formed as part of the frame member 202. Each female engaging portion 206a, 206b is tapered and arranged to receive a respective tapered male coupling portion 128a, 128b. In the first coupling position, the first coupling portion 128a is engageable with the first female socket 206a. In the second coupling position the first coupling portion 128a is engageable with the second female socket 206b. In the first coupling position, the second coupling portion 128b is engageable with the second female socket 206b. In the second coupling position, the second portion 128b is engageable with the first female socket 206a. In use, the use of a plurality of coupling portions 128a, 128b may enable a strong interlocking formation to be achieved between the first portion profile member 204 and the profile device 100 in the first interlocking arrangement and the second interlocking arrangement. However, it will be appreciated that the one or more engaging portions 206a, 206b need not be restricted to being one or female engaging portions 206a, 206b as shown. For example, each of the one or more engaging portions may comprise a male engaging portion for engaging with a respective female coupling portion located on the profile device. Furthermore, the one or more engaging portions 206 need not necessarily be homogenously formed as part of the frame member 202 and may, for example, comprise one or more fasteners for fastening the profile device 100 thereto, wherein each of the one or more coupling portions 128a, 128b of the profile device 100 are arranged to receive a respective fastener located within or protruding through the frame member 202.

[0188] As shown in the Figures 3 to 6, the profile member body 208 of the first portion profile member 204 is configured in both interlocking arrangements formable with the profile device 100, to extend in the first direction. The profile member body 208 of the first portion profile member 204 is also a longitudinal body 208 and extends in the second direction. As shown, the height direction corresponds to a vertical direction; however, height direction will be understood by the skilled person to also encompass inclined orientations, for example, when the window assembly is situated on a pitched roof. Accordingly, the first direction may also be described as being perpendicularly arranged relative to the surface on which the window is located. For example, in the flat root window system shown, the flat roof extends in a horizontal direction and the first direction is a vertical direction. In a pitched roof that inclines at an angle, the pitched roof has an inclined surface plane parallel to the pitched roof surface, and the first direction is perpendicularly arranged relative to the inclined surface plane of the roof. In other applications, such as vertical windows, or door systems for example, the first direction is perpendicular to the major plane of the door surface or glazing unit surface. Accordingly, the recess formable may be adjusted in a width direction in these applications.

[0189] In Figures 3 and 4, the profile device 100 is coupled to the first portion profile member 204 to form the first interlocking arrangement. In Figures 5 and 6, the profile device 100 is coupled to the same first portion profile member 204 to form the second interlocking arrangement. The first interlocking arrangement and the second interlocking arrangement are asymmetrically formed in the first direction. By asymmetrically formed in the first direction, it is meant that the interlocking formations are displaced relative to each other in the first direction.

[0190] The profile member body 208 of the first portion profile member 204 comprises a first end 212a and a second end 212b. The first end 212a as shown in the non-limiting example is a top end 212a. The second end 212b is a bottom end 212b. The second end 212b comprises a bent portion 214. The fixed length of the first portion profile member 204 is defined between the first end 212a and the second end 212b of the profile member body 208.

[0191] As shown in Figures 3 to 6, at least part of the first portion profile member 204 is arranged, in use, to be proximal to a peripheral edge of the glazing unit 302. The first portion profile member 204 is sealable to the glazing unit 302 using a sealing means, such as silicone sealant to fix the glazing unit 302 thereto. Similarly, the profile device 100 is sealable to the glazing unit 302 using a sealing means to seal the profile device 100 to the glazing unit 302.

[0192] When in the first coupling position, the profile device 100 is couplable to the first portion profile member 204 to provide the recess with a first recess depth, as shown in the first interlocking formation formed. The first recess depth substantially corresponds to the first glazing unit thickness. As shown in Figures 3 and 4, the recess formed in the frame member 202 for receiving part of a glazing unit 302 flushly receives the peripheral edge of the first glazing unit 302a.

[0193] When in the second coupling position, the profile device 100 is couplable to the first portion profile member 204 to provide the recess with a second recess depth that is different to the first recess depth of the recess. The second recess depth substantially corresponds to the second glazing unit thickness. As shown in Figures 5 and 6, the recess formed in the frame member 202 for receiving part of a glazing unit 302 flushly receives the peripheral edge of the second glazing unit 302b.

[0194] Accordingly, the profile device 100 is operable to control the depth of the recess formed in the frame member 202. In particular, the profile device 100 is operable to control the depth of the recess formed by being selectively arrangeable in the first coupling position or the second coupling position for subsequent coupling to the first portion profile member 204.

[0195] As shown in Figure 4, the first offset coupling portion 128a is engaged with the first female socket 206a to form a first interlock. The interlock formed between the first offset coupling portion 128a and the female socket 206a lies in an first interlocking plane, the interlocking plane being perpendicularly arranged relative to the first direction. The first interlocking plane is offset relative to the central plane of the profile body 102. The first interlocking plane is offset relative to the central plane of the profile body 102 and parallel to the central plane of the profile body 102. The first interlocking plane extends through the centre of the interlock formed, and in particular, through the centre of the female socket 206a and the coupling part 130a of the coupling portion 128a engaged to form the interlock. Accordingly, the interlock plane bisects the first offset coupling part 130a of the first interlocking plane.

[0196] Additionally, in Figure 4, the second offset coupling portion 128b is engaged with the second female socket 206b to form a second interlock. The second interlock formed between the second offset coupling portion 128b and the female socket 206b lies in a second interlocking plane, the interlocking plane being perpendicularly arranged relative to the first direction. The second interlocking plane is offset relative to the central plane of the profile body 102. The second interlocking plane is offset relative to the central plane of the profile body 102 and parallel to the central plane of the profile body 102. The second interlocking plane extends through the centre of the interlock formed, and in particular, through the centre of the female socket 206b and the coupling part 130b of the coupling portion 128b engaged to form the interlock. Accordingly, the interlock plane bisects the second offset coupling part 130b of the second interlock. The first offset distance may be defined as the spacing between the first interlocking plane and the central plane in the first direction. The second offset distance may be defined as the spacing between the second interlocking plane and the central plane in the first direction.

[0197] The profile device 100 is useable to switch the first portion profile member 204 between the first position and second position. Furthermore, the profile device 100 is useable to selectively fix the first portion profile member 204 along the first direction in the first position or the second position relative to the profile device 100. The first portion profile member 204 is moveable between the first position and the second position by axial displacement of the first portion profile member 204 in the first direction. The displacement distance between the first position and the second position may substantially correspond to the difference in thickness between the first glazing unit 302a and second glazing unit 302b. By displacement distance, it will be understood that this refers to the translation distance defined between the first position and the second position in the first direction.

[0198] The profile device 100 is configured, in both interlocking arrangements formable by coupling of the profile device 100 to the first portion profile member 204, to be positionally fixed in the first direction, and in particular positionally fixed relative to the first portion profile member 204 in both interlocking formations, as shown in Figures 3 to 6.

[0199] The frame member 202 is configured to retain the glazing unit 302 in both the first interlocking arrangement and the second interlocking arrangement formable. The frame member 202 is configured to securely retain the glazing unit 302 in both the first interlocking arrangement and the second interlocking arrangement formable.

[0200] As shown, the frame member 202 is configured, in use in the frame assembly 200, to securely retain the part of the first glazing unit 302a within the recess formed in the first interlocking arrangement. The frame member 202 is also configured, in use in the frame assembly 200, to securely retain the part of second glazing unit 302b having a second glazing unit thickness that is different to first glazing unit thickness within the recess formed in the second interlocking arrangement. By in use in the frame assembly 200, it will be understood that this refers to assembled frame and by securely retain, it is meant that the glass will not topple or fall, which may be relevant when applied to, for example, a vertical window assembly or door system.

[0201] In the non-limiting example shown, the window system 400 is a roof window system 400, and in particular a flat roof window system 400. The window system 400 has a support member 404. In this example, the support member 404 comprises an upstand 404. The upstand 404 may be an insulated upstand 404. The glazing system 300 is supportable on the upstand 404 and may be fixed to the upstand 404 in any suitable manner, such as being adhesively fixed to and / or mechanically fixed to the upstand 404, for example. The glazing system 300 may be hingedly fixed to the support member 404 so that the window system 400 may be moved between an open position and a closed position.

[0202] However, it will be readily appreciated that the glazing system may be suitably used in other applications, such as in a door system or façade element or vertical window assembly. In these arrangements, the first direction may be the transverse direction, such that the first frame profile member 204 is adjusted in the width direction, rather than the height direction as shown in the example window system 400. In these arrangements, the first profile frame member 204 may have an L-shaped cross-section, such that, at the first end of first profile frame member 204, an extension is arranged perpendicularly to the profile member body 208, and thus the recess has a two side supporting portions extending along the longitudinal direction of the frame member to retain the glass in position.

[0203] Now referring to Figures 7 and 8, there is shown another example of a window system 800. The window system comprises a glazing system 700. The glazing system 700 comprises a glazing unit 702 selectable from a first glazing unit 702a having a first glazing unit thickness or a second glazing unit 702b having a second glazing unit thickness. The glazing system 700 also comprises a frame assembly 600 comprising one or more frame members 602 (one shown). The frame member shown 602 comprises a first portion 602a and a second portion 602b. The first portion 602a of the frame member shown 602 comprises a first portion profile member 604. The second portion 602b of the frame member 602 shown comprises a profile device 500. The profile device 500 shown in Figures 7 and 8 is similar to the first example of the profile device 100 shown in Figures 1 to 6, and the differences between the profile devices are described in further detail below.

[0204] In Figures 7 and 8, the profile device 500 shown has a profile body 502 comprising a plurality of surfaces 504, 506, 508, 510, 512. The profile body 502 is an elongate profile body 502. In the example shown in Figures 7 and 8, the profile body 500 is formed from metal, such as aluminium.

[0205] Furthermore, the profile device 500 is a reinforced profile device 500. In particular, each hollow channel 526 of the plurality of hollow channels 526 formed in the interior space of the reinforced profile device 500 comprises an insert member 532. The insert member may be an insulation member 532. The insert member 532 may be functionable to reinforce the profile device 500.

[0206] The one or more coupling portions 528 of the profile device 500 shown in Figures 7 and 8 differs from the profile device 100 shown in Figures 1 in that, rather than the one or more coupling portions 528 being homogenously formed as part of the profile body 502, in the example shown, the one or more portions 528a, 528b of the coupling side 518 of the profile device 500 are integrally formed with the profile body 502. In other words, the one or more portions 528a, 528b are coupled to a part of the profile body 502. In particular, the first coupling portion 528a and the second coupling portion 528b each comprise a thermal barrier coupling member in the form of a thermal barrier strip 528a, 528b. Each thermal barrier strip 528a, 528b is formed from a thermally insulating plastic, such as polyamide. Each thermal barrier coupling member 528a, 528b is coupled to a respective thermal barrier receiving means 533 for coupling the thermal barrier member thereto 528a, 528b. The thermal barrier receiving means 533 is located on the coupling surface 508 of the profile device 500. Each thermal barrier coupling member 528a, 528b is further couplable to the engaging portion located on the first portion profile member to form the first interlocking arrangement, as shown in Figure 7, and the second interlocking arrangement, as shown in Figure 8. Each thermal barrier coupling member 528a, 528b is operable, in use, to prevent heat transfer between the first frame portion 602a and the second frame portion 602b of the frame assembly 600. Additionally, an insert member 534 is located between the first coupling portion 528a and the second coupling portion 528b of the profile device 500.

[0207] Additionally, the profile device 500 shown in Figures 7 and 8 comprises a gripping means 536 to grip a glazing seal member 538. In particular, the profile body 502 has a second side 522 opposite to and spaced apart from the coupling side 518. In the example shown in Figure 7 and 8, the second side 522, and in particular the second surface 512 comprises the gripping means 536, said gripping means 536 extending from the second surface 512 of the profile body 502. It will be appreciated, however, that other surfaces of the profile body 502 could be suitably implemented with the gripping means 536, such as the first surface 504 or the second surface 506. The gripping means 536 comprises a first glazing seal gripping portion 540a and a second glazing seal gripping portion 540b. In use, rather than using an adhesive to sealably secure the glazing unit to the profile body 502, a user assembling the glazing system may insert a removably insertable glazing seal member 540 to form a seal between the glazing unit and the profile body 502. The glazing seal member 540 is insertable into either the first glazing seal gripping portion or the second glazing seal gripping portion depending on whether the first interlocking formation or second interlocking formation is desired.

[0208] Now referring to Figures 9 and 10, there is shown another example of a window system 1200. The window system 1200 comprises a glazing system 1100. The glazing system 1100 comprises a glazing unit 1102 selectable from a first glazing unit 1102a having a first glazing unit thickness or a second glazing unit 1102b having a second glazing unit thickness. In the example window system shown in Figures 9 and 10, the difference in thickness between the first glazing unit 1102a and the second glazing unit 1102b is greater compared to the previous example window systems shown 400, 800. The glazing system 1100 also comprises a frame assembly 1000 comprising one or more frame members 1002 (one shown). The frame member shown 1002 comprises a first portion 1002a and a second portion 1002b. The first portion 1002a of the frame member shown 1002 comprises a first portion profile member 1004. The second portion 1002b of the frame member 1002 shown comprises a profile device 900. The profile device 900 shown in Figures 9 and 10 is similar to the previous examples shown in Figures 1 to 8, with the main differences being described below.

[0209] In Figures 9 and 10, the profile device 900 shown has a profile body 902 comprising a plurality of surfaces 904, 906, 908, 912, the plurality of surfaces 904, 906, 908, 912 being arranged to define an interior space therebetween. In the example shown, only four surfaces are provided, rather than five as shown in the devices 100, 500. The profile body 902 is an elongate profile body 902. In the example shown in Figures 9 and 10, the profile body 902 is formed from metal, such as aluminium.

[0210] In the example shown in Figures 9 and 10, the second surface 912 has a gripping means 936, the gripping means 936 being the same gripping means 936 as described in Figures 7 and 8. The profile device 900 is similarly a reinforced profile device 900, with each channel of the plurality of hollow channels 926 comprising an insert member 932.

[0211] In order to better support the glazing unit 1102 of the glazing system 1100, the window system 1200 has a wider upstand 1204 in comparison to the previous window systems shown, 400, 800.

[0212] Now referring to Figures 11 to 12, there is shown another example of a window system 1600. The window system 1600 comprises a glazing system 1500. The glazing system 1500 comprises a glazing unit 1502. The glazing system 1500 also comprises a frame assembly 1400 comprising one or more frame members 1402 (one shown). The frame member shown 1402 comprises a first portion 1402a and a second portion 1402b. The first portion 1402a of the frame member shown 1402 comprises a first portion profile member 1404. The second portion 1402b of the frame member 1402 shown comprises a profile device 1300.

[0213] In the present example, the profile device 1300 shown in Figures 11 to 12 is the same as the profile device 900 shown in Figures 9 and 10, and similar to previous examples shown. For example, the profile body 1302 of the device has a central plane extending through the profile body 1302 that is perpendicular relative to the first direction, the first direction being a height direction in the non-limiting example shown. The coupling side 1318 has one or more coupling portions 1328, and in particular, two coupling portions 1328a, 1328b, wherein each coupling portion 1328a, 1328b is engageable with an engaging portion, of the one or more engaging portions 1406, located on the first portion profile member 1404 such that the profile device 1300 is couplable to the first portion profile member 1404 to form a recess for receiving a part of the glazing unit 1502.

[0214] As best shown in Figure 11, the profile device 1300 is configured to be couplable to the first portion profile member 1404 in a coupling position, which, in the non-limiting example, is a first coupling position. In this (first) coupling position, the profile device 1300 is couplable to the first portion profile member 1404 to form a first interlocking arrangement in which the first portion profile member 1404 is fixed, relative to the profile device 1300, in a first position along the first direction.

[0215] As shown in Figure 11, and in contrast to the previous non-limiting examples shown, there is provided at least one spare engaging portion 1406a, and in particular, one spare engaging portion 1406a that is not engaged to form an interlock, and more particularly, an interlock with the profile device 1300 in the first interlocking arrangement. Thus, it will be appreciated that in the present example, when the profile device 1300 is arranged in the (first) coupling position, the profile device 1300 is further couplable with the same first portion profile member 1404 to form one or more additional interlocking arrangements in which the first portion profile member is fixed, relative to the profile device, in a different position along the first direction relative to the first position. In an additional interlocking arrangement not shown when the profile device 1300 is in the (first) coupling position, the engaging portion 1406a that is arranged as the at least one spare engaging portion shown in Figure 11 may form a first interlock with coupling portion 1328a, and a second interlock may be formed between a second engaging portion 1406b with the other coupling portion 1328b. Thus, in this additional interlocking arrangement not shown, the third engaging portion 1406c, which is engaged with coupling portion 1328b as shown in Figure 11, will not be engaged to form an interlock. In both the one or more additional interlocking arrangements not shown and the first interlocking arrangement shown in Figure 11, the first surface 1304 is located proximally to the major plane of the glazing unit 1502. In both the one or more additional interlocking arrangements formable when the profile device 1300 is arranged in the (first) coupling position, the recess formed is provided with a depth that is different to the depth of the recess formed in the first interlocking arrangement. Beneficially, this enables the same frame assembly 1400 to accommodate two (or more) different thicknesses of glazing unit without having to manufacture a different frame assembly.

[0216] In the non-limiting example shown and as described above, there is provided at least one spare engaging portion 1406 in the first interlocking arrangement and the one or more additional interlocking arrangements. It will be appreciated however, that other alternative configurations may be suitably used. For example, rather than there being provided at least one spare engaging portion as illustrated in Figure 11, there may instead be provided at least one spare coupling portion, or even a combination of at least one spare engaging portion and at least one spare coupling portion in any of the interlocking arrangements formable. For example, the at least one spare coupling portion may include a thermal barrier receiving means that does not have a thermal barrier coupling member coupled thereto or alternatively, has a thermal barrier coupling member coupled thereto that is not engaged to form an interlock.

[0217] In the present non-limiting example, the one or more coupling portions 1328 include a number N of coupling portions, and in particular, two coupling portions 1328a, 1328b. In other words, the one or more coupling portions 1328 is a plurality of coupling portions 1328. The one or more engaging portions 1406 include a number N of engaging portions, and in particular, 3 engaging portions 1406a, 1406b, 1406c. In other words, the one or more engaging portions 1406 is a plurality of engaging portions 1406. In some examples, the number N of engaging portions 1406 may be greater than the number N of coupling portions 1328. In this way, there can be provided at least one spare engaging portion in any interlocking arrangement formable. The number N of engaging portions 1406 is greater than the number N of coupling portions 1328 by an integer value that is equal to one. However, in other examples, the number N of coupling portions 1328 may be greater than the number N of engaging portions 1406 by an integer value of more than 1. Thus, where there is an excess number of engaging portions 1406, there will be provided at least one spare engaging portion 1406 in any interlocking arrangement formable. In yet other examples, the number N of coupling portions 1328 may be greater than the number N of engaging portions 1406. In this way, there can be provided at least one spare coupling portion 1328 in any interlocking arrangement formable. Yet further alternatively, the number N of coupling portions 1328 may be equivalent to the number N of engaging portions 1406. Where the number N of coupling portions 1328 is equivalent to the number N of engaging portions 1406, in order to provide at least one spare coupling portion and / or at least one spare engaging portion, it will be appreciated that the number N of engaging portions 1406 and the number N of coupling portions 1328 will be two or more. Furthermore, it will be appreciated that only some of the two or more coupling portions 1328 and only some of the two or more engaging portions 1406 may be engaged to form interlocks.

[0218] In the present example and as best shown in Figure 12, the profile device 1300 is also configured to be couplable to the same first portion profile member 1404 in a second coupling position, as previously described for the example shown in Figures 9 and 10. The profile device 1300 is switchable between the first coupling position and the second coupling position by rotation of the profile device 1300 about at least one rotational axis of the profile device 1300, which in this example is a transverse axis. In contrast to the example shown in Figure 9 and 10, in the second coupling position, the profile device 1300 is also couplable to the same first portion profile member 1404 to form one or more additional interlocking arrangements with the same first portion profile member 1404. In an additional interlocking arrangement not shown when the profile device 1300 is arranged in the second coupling position, the third engaging portion 1406c may be arranged to form an interlock with the coupling portion 1328a, the second engaging portion 1406b may be arranged to form an interlock with the coupling portion 1328b, and the first engaging portion 1328a may be a spare engaging portion 1406a.

[0219] As per previous examples described, the one or more coupling portions 1328 of the coupling side 1318 includes one or more offset coupling portions 1328 wherein the, or each, offset coupling portion 1328a, 1328b is offset relative to the central plane of the profile body 1302. As shown in the non-limiting example in Figure 9 and 10, the one or more offset coupling portions 1328 includes a plurality of offset coupling portions 1328. The plurality of offset coupling portions 1328 includes a first offset coupling portion 1328a and a second offset coupling portion 1328b, wherein the first offset coupling portion 1328a and second offset coupling portion 1328b are offset from the central plane (CP). The first offset coupling portion 1328a is offset from the central plane (CP) by a first offset distance, and the second offset coupling portion 1328b is offset to the central plane (CP) by a second offset distance that is non-equivalent to the first offset distance. The first offset coupling portion 1328a and the second offset coupling portion 1328b are asymmetrically offset from the central plane (CP). It will be appreciated however that in the present example, with the provision of at least spare coupling portion and / or at least one spare engaging portion in any of the interlocking arrangements formable, the use of symmetrically arranged coupling portions or a single coupling portion lying in the central plane may be possible. For example, a symmetrically arranged offset pair of coupling portions in the coupling position may be engageable with a first group of a plurality of engaging portions to form the first interlocking arrangement. The symmetrically arranged offset pair of coupling portions, in the (first) coupling position, may further be couplable to a second group of the plurality of engaging portions to form an additional interlocking arrangement in which the first portion profile member is adjusted in the first direction such that is the first portion profile is in a position that is different to the position which the first portion profile member is arranged in the first interlocking arrangement. For example, the first position may be a first height, and the different position may be a different height relative to the first position.
