The first channels are typically provided adjacent respective corners of the frame member with the second channel provided in a central portion of at least one side.

Description

Frame system The present invention relates to a frame system, particularly a frame system for supporting temporary signage or building structures.

Introduction

Frame systems are commonly used to support temporary structures, such as signs or banners or the like. Such frame systems are often used at exhibitions, where a printed textile is held tight by the frame. Frame systems of this type may also be used to hold rigid board or glass, e.g. to define a wall-like structure to be used as a partition or wall of a temporary enclosure.

A prior art frame system is provided in EP1646792. A sheet 5 is overlaid a frame 3, and the edges of the sheet 5 are retained within a peripheral groove 4 formed on the frame 3. The sheet 5 comprises graphics or text etc. to provide the banner or sign. The sheet 5 is retained within the groove 4 using a retaining member 14, commonly referred to as a lone. The jonc comprises a plurality of flexible wings 12. The jonc 14 is overlaid the sheet 5 and pushed/hammered into the groove, thereby trapping the sheet 5 between the jonc and the groove 4. As the jonc 14 is pushed into the groove 4, the wings 12 flex inwards and then expand back outwards once within the groove 14, thus retaining the jonc 14 therein.

The inventor has found numerous problems with the prior art system provided in EP1646792. During the construction of such systems, the frame is cut to size to according to the size of the banner. However, as banners may vary in shape and size, a bespoke frame must be created for each individual banner. This is time consuming and generates considerable waste as each frame may only be used once or a limited number of times. This increases the cost of such systems and requires the storage of a large number of different sizes of frame.

Additionally, the frame is assembled by bolting the frame members together. Again, this is time consuming and reduces the reusability of each frame, for example, as holes need to be drilled into the frames to attach the bolts.

Furthermore, different sizes of frame and different frame applications may require different attachment means, e.g. other than the jonc described above. For example, there are very different considerations for internal and external usage of frame systems, e.g. to accommodate possible thermal expansion and/or wind loading. The desire to accommodate a variety of different applications and sizes of frame hampers the availability of a universal frame system that can accommodate all such potential uses.

It is an aim of the present invention to overcome more or more of the above problems, for example, to provide a more flexible and universal frame system.

Figures la and lb show a frame member 2 for use in a frame system. As shown more clearly in figure 3, a plurality of frame members 2 are assembled in use to define a frame 4 in which a sheet 6 is mounted to provide a banner, sign or the like. The sheet typically comprises a flexible sheet, such a fabric/textile or flexible plastic sheet, although rigid sheets -e.g. boards, glass or similar -can be supported by the frame if desired. The sheet 6 may comprise text, graphics or images etc. Additionally, the frame 4 may support or accommodate one or more light (not shown) to provide a backlight for the banner.

The frame is typically rectangular in form once erected, although other polygonal shapes could potentially be accommodated if desired.

The frame system is typically used to provide a temporary or semi-permanent structure. For example, the frame system may be used at events, conferences, festivals etc. The system may be constructed at the side and then deconstructed once no longer required. The frame members 2 are therefore typically detachable from one another such that they may be re-used. Additionally, this allows larger systems than could be carried on a vehicle to be constructed. When used internally within an existing building, the frame system may be used to provide a more permanent display or partition wall, although the frame system is easily deconstructed if desired.

The frame member 2 comprises an elongate strut or beam. The beam is substantially hollow, e.g. being tubular in form, thereby reducing the weight thereof. The beam may be formed by extrusion, for example, the beam may comprise an aluminium extrusion. The features of the frame member 2 shown in section in any of the examples of figures 2 and 4-7 are typically constant along the length of the frame member. Thus any lengths of the frame member 2 can be formed and cut to the desired length.

Typically, the frame member 2 is linear/straight in form, however, it can be appreciated that some sections may be curved or angled (e.g. to form angled 25 corners).

Turning to figure 2, the frame member 2 comprises a first channel 8a configured to receive a retaining member to secure the sheet 6 onto the frame member 2 (see figure 9). The channel 8a is delimited by a plurality of side walls 10a,b and a bottom wall 12. The first channel 8a comprises a plurality of inwardly extending flanges 14 configured to retain the retaining member. The flanges 14 are located at substantially the same height as one another (i.e. displaced at a similar distance from the bottom 12 of the first channel). The spacing/gap between the flanges 14 thus defines an opening 16 (e.g. a neck formation) therebetween. The channel 8a is thus closed at its base but has an outwardly facing opening 16 to receive a retaining member in use.

The first channel 8a is provided on a side 18a of the frame member 2 (i.e. the side walls 10 protrude therefrom). The first channel 8a is provided adjacent a corner 20a of the frame member. A second first channel 8b is provided at the corner 20b on the opposing end of the side 18a of the frame member 2. Thus each corner 20 of the frame member 2 comprises two first channels 8, one at each adjoining side of the corner. In the embodiment shown in figures 1 and 2, this arrangement is repeated at all four corners of the frame member 2 and/or on all sides18b-d of the frame member 2.

The first channels 8 are provided adjacent one another at the respective corners 20. The adjacent first channels 8 are therefore angled with respective to one another (i.e. at right angles). The adjacent first channels 8 share a common intermediate wall 10a. The common intermediate wall 10a may also be referred to as an oblique/side wall and it bisects the corner 20 (i.e. extends at 45 degrees relative to the sides 18. This arrangement gives the first channels 8 a right-angled trapezium shape. The common side wall 10a comprises a plurality of flanges 14, e.g. defining an arrow like shape in section.

Eight of the first channels 8 are provided in the example of figure 2 and are labelled 8a-8h. The channels 8 and their respective openings 16 are of common dimensions.

A grip surface 22 is provided on the flanges 14, adjacent the opening 16. The grip surface 22 comprises a plurality of parallel ridges/grooves (e.g. a saw tooth like configuration). In other embodiments, the grip surface 22 comprises a roughened surface texture and/or a high-friction finish.

A second type of channel 24 is provided between the first channels 8 on each side of the frame member. The second type of channel 24 is configured to a receive a connection member to allow attachment of a further frame member to the frame member 2 (see figure 10d). The second channel 24 comprises a plurality of sides walls 10b and a bottom wall 26. The second channel 24a on side 18a is provided adjacent and between the two first channels 8a and 8b and shares a common wall 10b with each of them. One of the second channels 24a-24d is provided on each side 18a-18d of the frame member 2.

The second channel 24a comprises a plurality of inward facing flanges 28 configured to retain the retaining member in use. The flanges are provided on the side wall 10b and define an opening 30 therebetween. The second channel 24a is therefore substantially rectangular.

The second channel 24 is provided in a centre of the frame member side 18 (i.e. the centre of the channel 24 is aligned with the centre of the side 18). In alternative embodiments, the second channel 24 may be offset from the centre of the side 18. In each second channel 24, there may be provided a central groove or indent for alignment purposes during construction of a frame.

The second channel 24a is offset radially/inwardly relative to the first channels 8a,b. This is common on all sides of the frame member 2. The second channel bottom wall 26 is therefore offset toward the centre of the frame member 2 relative to the first channel bottom wall 12.

The second channel flanges 28 are also offset inwardly relative to the first channel flanges 14. The flanges 28 are therefore provided part way along the side walls 10b.

The second channel 24a is shallower than the first channel 8, e.g. the height between the base and the flanges of the second channel is a fraction of, e.g. approximately half, the height of the first channel 8.

The opening 30 of the second channel 24a is different from the openings 16 of the channels 8, e.g. being wider in this example. The opening 30 may be between 1 and 3 times wider than opening 16, e.g. approximately double the width. The flanges 28 of channel 24a may be the same as, or different from, the flanges 22 of channels 8.

The second channel 24a thus has one or more different dimension from the first channel 8a, e.g. comprising a difference in channel width, channel depth, radial position and/or opening width.

Such an arrangement is repeated on each of the side 18b-d, thereby providing a second channel 24a-d on each side of the frame member 2. The frame member 2 is substantially square. The frame member 2 therefore comprises 4-fold rotational symmetry. The flanges 14 are aligned and colinear on each respective side 18 of the frame member 2, thus the flanges 14 collectively define a rectangular net shape.

In alternative embodiments, the first and second channel arrangement may only 20 be provided a single or a select number of sides 18 of the frame member 2.

A second embodiment of the frame member 2 is shown in figure 4. The second embodiment is similar the first embodiment, however, the frame member 2 only comprises the channel arrangement of the first side 18a, and the adjacent corner first channels 8c,h of the second and fourth sides 18b,d respectively. The third side 18c is substantially flat and extends between the side walls 10b of the corner channel 8c,h. The frame member 2 is therefore truncated in line with the side walls 10b. The second embodiment provides a compact configuration and the flat side 18c a more aesthetically pleasing surface.

A third embodiment is shown in figure 5. The third embodiment is substantially the same as the first embodiment, however, the second channels 24 are spaced from the first channels 8 (i.e. do not share a common wall) along each side. The profile of the third embodiment is thus larger/wider than the first embodiment such that gaps exist between the first 8 and second 24 channels on each side of the frame member.

The spacing between the first 8 and second 24 channels may provide a third channel 32a. The third channel 32a shares common walls 10b,c with the first channel 8 and the second channel 24 respectively. The third channel 32 is outwardly offset from the first channel 8 (i.e. is shallower). The third channel 32a is substantially L-shaped, e.g. having only a single flange instead of a pair of flanges to define its opening.

The third channel 32a comprises an inwardly extending flange 36 to provide retention of a retaining member. The second channel 24 comprises a second plurality of flanges 38 aligned with the third channel flanges 36. The second and third channel flanges 36,38 are aligned with the first channel flanges 14. The second channel 24 has two optional sets of flanges in this example, thereby defining two openings, one radially inside the other in a stacked manner.

A further third channel 32b is provided on the opposing side of second channel 24 in a mirrored arrangement. The second channel 24 is thus interposed between a plurality of third channels 32, which are interposed between a plurality of first channels 8. This arrangement is repeated on each side of the frame member 2.

A fourth embodiment of the frame member 2 is shown in figure 6. A first second channel 24a extends across the first side 18a of the frame member 2. A second channel 24b is provided on an opposing position on third side wall 18c.

A plurality of first channels 8a,d are provided on the fourth side 18d. The first channels 8a,d are provided in a side-by-side arrangement, i.e. without a second channel there-between. A second plurality of first channel 8b,c are provided on the opposing second side 18b. The first channels 8b,c share a common wall 10a, as do the channels Bad. The common walls 10a comprises a plurality of flanges 14, in a T-shaped arrangement. The common wall 10a is provided at a centre of the opposing sides of the frame member and extends perpendicular thereto.

The first channels 8 laterally extend past corners 20 of the frame member 2 (i.e. past the bottom 26 of the second channel 24). The second channel 24 is therefore sandwiched between the first channels 8a,b, although it is located on a different/intermediate side of the frame member relative to the first channels 8. The bottom wall 12 of the first channel 8 provides the side wall of the second channel 24. The side wall 10b of the first channel 8 is co-linear with the second channel flange 28. The side wall 10b, second channel flange 28 and the first channel flange 14 thus define an [-shape.

The bottom wall 26 of the second channel 24 comprises a recess 40 therein. The recess 40 is substantially trapezoidal. The recess 40 only occupies a portion of the bottom wall 26. The recess 40 is provided is central portion of the bottom wall 26 (i.e. the recess 40 is aligned with the opening 30).

A fifth embodiment of the frame member 2 is shown in figure 7. The frame member 2 comprises a substantially planar member, i.e. having a flatter profile or reduced height compared to the preceding embodiments. A second channel 24 is provided on a first side 18a. The second channel comprises a pair inwardly extending flanges 28 and a pair of outwardly extending flanges 42. The outward flanges 42 are outwardly offset from the inward flanges 28.

A plurality of first channels 8 are provided at opposing ends of the frame member 2. The first channels 8 comprises a simple rectangular shape. The first channels comprise an opening 16 which is perpendicular to the opening 30 of the second channel 24.

The remaining side 18c is substantially linear/planar. The side 18c is continuous/co-linear with the side walls of the first channel 8a,b.

The first channels 8 are laterally spaced from the second channel 24. The spacing is provided by a chamfered section 43a, with the chamfer surface facing the first channels 8. The second channel 24 is vertically spaced from the first channels 8.

The vertical spacing is provided by a substantially rectangular section 43b.

The frame member 2 cross-sectional shapes herein described will typically extend along the full length of the frame member 2. The cross-sectional shape of the frame member 2 will thus remain constant along the length thereof. However, in other embodiments, the cross-sectional shape may vary and/or be discontinuous along the length thereof (i.e. one or more of the channels are provided in select portions of the frame member 2).

A first embodiment of the retaining member 44 is shown in figures 8a-8c. As previously discussed, the retaining member 44 is configured to be inserted into the first channel 8 to retain the sheet therein by way of a close fit within the channel 8. Such a retaining member is commonly called a retaining strip and will be referred to from herein by such a term.

The retaining strip 46 comprises a flexible member 48 configured to be inserted into the first channel 8 and to engage the flanges 14 to retain the retaining strip 46 therein. The flexible member 48 comprises a plurality of arms 50. The arms 50 are flexible to allow lateral compression of the flexible member 48 (i.e. by bending of the arms 50). The arms 50 comprise a laterally extending ridge/protrusion 51. The ridge 51 is formed by a first angled portion 50a extending laterally outward from the arms 50. A second angled portion 50b extends from the first angled portion 50a in a laterally inward direction. The arms 50 thus comprises a linear portion and an arrow/chevron shaped portion. The apex of the chevron portion faces an outward direction. The retaining strip 46 is table or "pi" shaped.

During insertion, the ridges 51 engage the flanges 14 of first channel 8. The second angled portion 50b induces a lateral compression/flexion of the arms 50 when pressed into the opening 16. The arms then expand into the channel 8 once the ridges 51 passes the flange 14, and the first angled portion 50a engages the inner side of the flanges 14 to retain the retaining strip 46 therein. The retaining strip 46 therefore snap fits into the first channel 8. During removal, the process is reversed and the first angled portion 50a induces a lateral compression of the arms until the ridge 51 passes the flanges.

In alternative embodiments, the flexible arms 50 are linked in a concertina like shape (i.e. defining an inverted "M"-shape).

The flexible member 48 is fixed to a top plate 52. The top plate 52 comprises a plurality of outstanding flanges 54. As shown in figure 9, in use the flanges Swill overlie the frame member 2 and engage the grip member 22 and/or frame 2, thereby helping to retain the sheet 6 therebetween. As shown in figures 8b and Sc, the retaining strip 46 is elongate, and may extend partially or fully along the length of the frame member 2, as required.

The retaining strip 46 comprises semi-flexible material (i.e. a material that maintains shape under its own weight, however, is flexible enough to allow a small amount of deformation). The retaining strip 46 may comprise a plastics material.

A first embodiment of the connection member 56 is shown in figure 10. As previously discussed, the connection member 56 is configured to engage the second channel 24 to provide a connection between a first frame member 2a and a second frame member 2b. The connection member is generally rigid and platelike, i.e. being flatter and/or wider than the flexible member of the retaining strip 46.

The connection member 56 comprises a first portion 58a configured to be received 30 in the first frame member 2a and a second portion 58b configured to be received in the second frame member 2b. The first and second portion are angled with respect to one another (i.e. to provide an angled bracket). In this present embodiment, the first and second portion are angled at 90 degrees with respect to one another. However, it can be appreciated that the first and second portion may be angled at any required angle, for example, 30 degrees, 45 degrees, 60 degrees, 120 degrees, 135 degree, 150 degrees etc, depending on the shape of the frame structure to be assembled.

The first and second portions are substantially rectangular. The width of the first and second portions substantially corresponds to the width of the second channel, such that connection member 56 is freely movable therein (i.e. along the axis of the frame member 2), however, is retained by the flanges 28. Thus, the connection member 56 can be slid along the channel 24 to the desired position.

The first and second portions are connected via a narrower neck portion 60. The width of the neck portion 60 substantially corresponds to the width of the second channel opening 30. This ensures the connection member 56 is receivable within the channel 24, but prevents any significant lateral movement or wobbling of the connection member therein.

The first and second portions comprises apertures 62 therein configured to receive a fastener 64 (see figure 10d), such as a threaded fastener. The fastener 64 may engage the frame member 2 (e.g. via an aperture therein, or by frictionally engaging the surface thereof) to retain the connection member 56 in place. In preferred embodiments, each fastener is engaged between the base 26 (see figure 2) of the channel and the aperture 62. Thus tightening of a threaded fastener biases the connection member 56 against the flanges 28, away from the channel base 26, and the connection member is firmly held in place by frictional engagement due to compression in the fastener during tightening. In this regard, apertures are no longer needed in the frame member and no drilling is required to connect frame members together. A groove may be provided in the base 26 of the second channels 30 to ensure correct fastener alignment during tightening.

The fasteners 64 may be partially released to allow the connection member 56 to slide along the second channel 24 to provide positional adjustment thereof. The fastener can then be tightened to fix the position of the connection member during assembly of the frame system.

A shown in figures 10c and 10d, the connection member 56 allows an angled connection between the frame members 2a,2b. Connection members 56 may be used in pairs, e.g. engaging the same or different channels of the frame members to create a secure connection.

Figure 10c shows the frame members 2a,2b provided in a mitre joint arrangement. The connection members 56 are provided on the inside corner 66a and the outside corner 66b of the joint respectively. Fasteners (not shown) fix the connection member 56 to the respective frame members 2a,2b.

Figure 10d shows the frame members 2a,2b provided in a butt joint arrangement. The connection members 56 are provided in an adjacent but opposing arrangement (i.e. the respective first portions 58a extend away from one another within a common channel). The connection members 56 therefore engage each side of the further/adjoining frame member 2b. The connection member 56 is then fixed to both frame member 2a,2b via fasteners 64. In the present embodiment, the butt joint is provided part way along the frame member 2a (i.e. a T-junction), however, it can be appreciated that the butt joint may be provided at an end of the frame member 2a, thus providing a corner butt joint.

A second embodiment of the connection member 56 is shown in figure 10b. In this embodiment, the first portion 58a and the second portion 58b are co-linear, thus providing a linear bracket. The bracket therefore provides end-to-end connection of frame members 2a,2b. The connection member 56 does not require a neck portion, as the bracket is configured to be contained with the respective second channels 24. The connection member 56 comprises apertures 62 therein. The connection 56 may be used to provide an end-to-end butt or scarf joint.

It can be appreciated that connection member 56 may be used to provide any joint type as required. For example, the joint may provide lap, rabbet, rub or dado joint.

A third embodiment of the connection member 56 is shown in figures lla and 11b. The connection member comprises a channel 64 configured to receive a frame member 2b therein. The channel 64 comprises a bottom wall 66 and parallel side walls 68, thus defining a U-shaped channel.

A plurality inward facing flanges 70 are provided on the underside of the bottom wall 66. The flanges 70 are spaced from the bottom wall 66. The flanges 70 are thus L-shaped. The flanges 70 are configured to engage either the flanges 14 of spaced first channels 8 (i.e. such that the connection member 56 spans second channel 24) or engage the flanges 36 of the third channels 32a,32b of the embodiment shown in figures (i.e. such that the connection member 56 spans the second and third channel 24). The flanges 14/36 of the first/third channels are thus sandwiched between the flanges 70 and the bottom wall 66 of the connection member 56 in use.

The flanges 70 are provided laterally inward from the side walls 68. Such an arrangement provides a wide base for connection of the frame member 2b, which typically comprises an intermediate frame member, e.g. a cross member part-way along a side/edge, rather than an outer side/edge of the frame structure once constructed.

As shown in figure 12, in this embodiment, the further frame member 2b comprises a "plain" rectangular tubular section (i.e. the walls of the frame do not comprise channels etc.). This allows the frame to be at least partially constructed conventional structural members. The frame member 2b slots into the channel 64 and a fastener or the like may be used to secure the frame member 2b therein, the frame member 2b may be secured at an angle as required by the user.

A fourth embodiment of the connection member 56 is shown in figure 13. The fourth embodiment is similar to the third embodiment in terms of its U-shape and flange arrangement. However, the side walls 68 are provided further inward than then side walls 68 of the third embodiment. The side walls 68 are thus provided laterally inward from the flanges 70. This arrangement is more suited for use with thinner frame member 2b.

Further embodiments are shown in figures 14 and 15. These embodiments are substantially the same as those shown in figures 12 and 13, however, the channel is laterally offset from a centre of the connection member 56. The side walls 68 are therefore offset from the centre of the bottom wall 66/centre point of the flanges 70. One of the side walls 68 is placed adjacent the end 72 of the bottom wall 66.

It can be appreciated that the connection member 56 may be used with the frame 15 member 2 as described in previous embodiments, with the side walls 68 engaging the outer walls (e.g. the flanges 14) of the frame member 2a.

In some embodiments, the flanges 70 may be outwardly facing. This allows the connection member 56 to be connected either of the inward flanges 28/38 on the 20 second channel 24 A seventh embodiment of the connection member 56 is shown in figures 16a and 16b. The connection member 56 is configured to be received within a further frame member 2b (i.e. received within a cavity/recess therein). The connection member 25 56 thus comprises a pin like member.

The connection member 56 comprises a retaining means 74 configured to be received within the first channel 8 between opposing flanges 22. The retaining means comprises a plurality of outwardly extending flanges 76 configured to engage the flanges 22 of the first channel 8. The outer, lower surface 77 comprises a chamfered surface. The flanges 76 thus comprise a latch, hook or P-shaped arrangement to prevent removal of the connection member 56 in a radial direction.

The connection member 56 comprises a first portion 78a and a second portion 78b. The first and second portion are pivotally connected via a pivot 80. The pivot is provided at opposing ends of the first and second portion relative to the flanges 76. The first and second portions are pivotable between a first configuration in which the flanges 76 are proximal or adjacent one another (i.e. the first and second portions are parallel or touching) and a second configuration in which the flanges 76 are displaced from another (i.e. the first and second portions are provided in a V-shape).

An end portion 82 of the second portion 78b is pivotally received with an end portion 84 of the first portion 78a (i.e. a channel 86 therein), thus defining the pivot 15 80. The end portion 82 comprises an arcuate surface configured to be received by the correspondingly shaped channel 86.

In the present embodiment, the end portion 82 comprises a C-shaped member. However, it can be appreciated that in other embodiments, the end portion 82 may be solid/circular. The channel 86 comprises a C-shaped member, with the opening in the C-shape allowing the degree of angular movement between the first and second portions.

An aperture/recess 88 is provided on the second portion, adjacent the end portion 82 thereof and an end 90 of the channel 86. When a retaining member is inserted into the aperture 88, pivoting of the first and second portion apart beyond the condition shown in figure 16a is prevented. Alternatively, a flexible or resilient member is provided within the aperture 88, thus biasing the flanges 76 together. Thus, the connection member 56 is itself a sub-assembly of pivoting members held together.

The first and second portion comprise a respective recess 94 therein. The recesses 94 are provided on an inner surface on the first and second portion in a facing arrangement. The recesses 94 thus collectively define an aperture 96. The aperture 96 may be rectangular/octagonal.

The relative angular orientation of the first 78a and second 78b portions is controlled using a threaded fastener 92 arranged to be inserted in aperture 102. The aperture 102 is only provided in one of the first portion 78a or second portion 78b, such that the fastener 100 passes through the aperture 102 and engages the other portion to bias the first and second portion apart. If the pin 92 is removed or fully retracted in the aperture 102, the flanges 76 can be brought together so they are narrower than the opening 16 in the first channel 8. This allows easy insertion or removal of the connection member 56 from the first channel S. When the pin 92 is inserted, e.g. being tightened using a threaded engagement, the flanges are forced apart to hold the connection member 56 in place in the channel Sand prevent removal thereof. This ensures the flanges 76 remain engaged within the channel 8 (e.g. against the bias of pin member in the aperture 88) to hold the connection member 56 at a desired location along the length of the frame member.

The connection member 56 may have a square/rectangular cross section (when looking down the axial length thereof). As shown in figure 17, the connection member 56 can be closely received within a rectangular recess 98 in the further frame member 2b. The connection member 56 is secured to the further frame member 2b via the fastener 92. The fastener is received within aperture 102 in the connection member 56 through an aligned aperture in the side of the recess 98, e.g. towards the end of the further frame member. This ensures the connection member 56 can be held in the correct position in the further frame member 2b such that the flanges 78 protrude for engagement in the relevant channel in the frame member 2a. Tightening of the fastener 92 thus splays the portions 78a and 78b to provide a secure fastening between the frame members 2a and 2b.

Using the connection member 56 described above, the first channel 8 can be used not only to receive a retaining member, such as a retaining strip, but also a connection member for another frame member.

As shown in figures 18a and 18b, a blanking member 104 may be provided. The blanking member comprises a retaining means 106 connected to a blanking surface 108. The retaining means 106 comprises a plurality of flanges that may be configured to attached to any of the channels on the frame member 2.

The blanking surface 108 comprises a surface configured to at least partially hide or obscure the frame member 2. This may improve the aesthetic properties or may prevent items (e.g. dirt or fingers etc) becoming trapped in the channels 8,24. The surface 108 is substantially planar (i.e. does not comprise channels, grooves, ridges etc. On its outward facing surface). In the present embodiment, the surface is substantially flat. In other embodiments, the surface may be curved, polygonal or other substantially planar shape.

The blanking member 104 may comprises a plastics material or a metal/aluminium material. The blanking member 104 may be coloured or comprise graphics etc. The blanking member 104 may extend substantially the length of the frame member 2. The blanking member 104 may be provided as a substantially continuously length, or may be provided as one or more discrete portion (as shown in figure 18b).

As shown in figures 19a and 19b, a spacer member 110 may be provided. The spacer is configured to space the sheet 6 away from the frame member 2. For example, this allows the installation of one or more lights in the available depth behind the sheet 6.

The spacer member 110 comprises a retaining means 112. The retaining means 106 comprises a plurality of flanges configured to engage the first channel 8 on the frame member 2, thus removably attaching the spacer 110 thereto.

The spacer 110 comprises a plurality of upstanding fins 114. The distal end 116 of the fins are configured to engage the sheet 6 in use. The fins 114 extend away from the retaining means 112 in parallel and are configured to extend along the length of the frame member 2 in use (e.g. resembling a heat sink arrangement). Any number of fins 114 may be provided, for example, in accordance with the width/height of the frame member 2.

The spacer 110 comprises a grip member 118 which cooperates with an opposing retaining member configured to retain the sheet 6 in use. The grip member 118 comprises a fin having an outstanding protrusion 120 facing an adjacent fin 114a.

The protrusion 120 is aligned with the end 116 of the adjacent fin 114a. In use, the retaining member cooperates with the protrusion 120 and the sheet 6 will be trapped between the fins 114a and 118 by the retaining member, and overlies the ends 116 of remaining fins 114.

A further example of finned spacer 110a is shown attached to the frame member 2 in figure 20. The flanges 112 are located within the first channel 8 and engage the flanges 14 thereof. In this embodiment, the spacer 110a does not comprise a grip member 118. The sheet 6 may be sandwiched between the bottom side 122 of the spacer and the grip means 22 of flange 14.

A further embodiment of the spacer 110 is shown in figures 21a and 21b. In this embodiment, the spacer 110 is configured to span the corner 20 of the frame member 2. The spacer 110 comprises a plurality of sides 124a,124b configured to engage a respective side 18a,18b of the frame member 2 in use. A plurality of fins 114 are provided of each side of the corner 20. The respective fins 114 on each side of the corner 20 extend substantially perpendicular to one another, thus the ends 116 of the fins 114 collectively define a corner 126 spaced from the frame member 2 corner 20.

The fins 114a adjacent the corner 126 comprise a branch portion 128 extending toward the corner 126. The fins 114a are therefore substantially forked or Y-shaped.

A corner fin 114b is interposed the fins 114a. The corner fin 114b bisects the fins 114b (i.e. is angled at 45 degrees with respect thereto). The corner fin 114b therefore provides an outmost/apex part of the corner 126.

The corner fin 114b comprises a protrusion/ridge 130 to allow gripping the of sheet 6 using a correspondingly shaped retaining member (not shown) in a manner similar to the embodiment of figure 19. The sheet 6 may be sandwiched between the retaining member and the adjacent fins 114a (and/or the respective branch 128), 114b. The protrusion 130 is provided part way along the fin 114b.

The spacer 110 comprises retaining means 132 configured to engage the first channels 8a,8b provided either side of the frame member corner 20. The retaining means 132 comprises a plurality of outwardly extending flanges 134 configured to engage the flanges 14 of the first channels 8a,8b (i.e. those distal the corner 20). The flanges 134 are provided on respect sides 124a,124b of the spacer 110. The flanges 134 therefore extend in substantially perpendicular directions.

A stop member 136 is configured to engage the flanges 14 proximal the corner 20. The stop member 136 therefore prevents any lateral movement of the spacer 110 within the channels 8a,8b.

Alternatively, the flanges 134/stop member 136 could be configured to engage one of the second channels 24 or third channels 32.

Another embodiment of the spacer 110 is shown in figure 22a. This embodiment provides a corner spacer as provided in figure 21. However, the fins 114 are provided in a parallel arrangement. The fins 114 extend in a direction bisecting the angle of the corner 20 of the frame member 2. In the present embodiment, the fins 114 extend in a direction angled 45 degrees relative to the sides 124a,124b of the spacer 110.

A branched fin is not required as the adjacent 114a extends parallel to the corner fin 114b. Additionally, the stop member 136 is not provided. Lateral movement 10 may be prevented by engagement of the corner flange 14 of the frame member 2 with the corner between the sides 124a,124b of the spacer 110.

A fourth embodiment of the spacer is shown in figure 22b. The fins 114 extend in a parallel direction. However, the distal ends 116 of the fins 114 are aligned. The spacer 110 thus provides a chamfered corner 126 (i.e. perpendicular sides interposed by an angled side). The angled side is angled at an angle perpendicular to the bisector of the corner 20 of the frame member. In this embodiment, the angled side is thus angled at 45 degrees relative to the sides 124a,124b of the spacer 110. Three fins 114 are provided, however, it can be appreciated that the number/spacing of the fins 114 can be varied to vary the width of the chamfered surface.

Alternatively, such a chamfered arrangement may be provided by truncating the corner fin 114b of the embodiments shown in figures 21 and 22.

In this embodiment, the retaining means 132 comprises a plurality a of respective flanges 134a,134b configured to engage both of the flanges 14 of the respective first channels 8a,8b.

It can be appreciated that the frame member 2 may comprise any cross-sectional shape as required, for example, a triangular, hexagonal, octagonal, polygonal, circular or arcuate shape. The corner spacer 110 will be modified accordingly to accommodate the angular arrangement of the corners 20 of the frame member 2. For example, in a hexagonal frame member 2, the sides 124a,124b of the spacer 110 will be angled at 120 degrees. The corner fin 114b will be angled at 120 degrees relative to the sides 124a,124b. The remaining fin 114 will either be perpendicular or angled at 120 degree relative to the sides 124a,124b, depending on the exact configuration. Similarly, in the chamfered configuration, the angled side will be angled at 30 degrees relative to the sides 124a,124b.

A fifth embodiment of the spacer member 110 is shown in figures 23a and 23b.

The spacer 110 comprises a channel 136 configured to a receive a retaining strip 48 to retain the sheet 6 therein. The spacer 110 therefore effectively provides a further first channel spaced from the first channel 8 on the frame member 2. The channel 136 comprises a plurality of flanges 138 to define an opening 140 therebetween. The flanges 138 comprise a grip means 142.

The spacer 110 comprises a back member 144 with a retaining means 146 thereon. The channel 136 is spaced from the back member 144 via an internal channel 148. The retaining means 146 comprises a plurality of flanges of the type already described above.

The spacer 110 comprises an angled surface 150. The angled surface 150 extends from the flanges 138 to a distal end 152 of the back member 144. The spacer 110 thus comprises a trapezoidal shape. The angled surface 150 provides a bevelled/chamfered surface on which the sheet 6 can extend around. This may be used to space the sheet 6 around a corner of the frame system. The angled surface 150 thus provides an aesthetically pleasing arrangement.

A sixth embodiment of the spacer 110 is shown in figure 24. This embodiment is similar to the fifth embodiment, however, the angled surface is not present. The spacer 110 is thus substantially rectangular.

The retaining means of aforementioned spacers 110 may be applied to any of the embodiments herein described. For example, the retaining means may comprise: a single flange member for each respective channel; a single flange member with a stop member; or two flange members.

Although the spacer member 110 have been described for attachment of the first channel 8, it can be appreciated that they may be configured for attachment to the third channel 32 and/or the second channel 24.

The words "vertically", "laterally", "sidewards", "top", "bottom" etc have been used to merely to aid with understanding of the invention. It can be appreciated such words are not limiting on the scope of the invention, and the system may be used in any orientation as required.

The present invention provides a modular system that allows a plurality of frame members to be attached to one another in a detachable way. This allows recycling of the frame member and permits more complex systems to be made. Additionally, this increases both and the speed and ease in which the frame system can be constructed/deconstructed.

The use of separate channels for attaching the sheet and the frame member reduces the chance of incorrectly assembling the system and allow for a more flexible arrangement of different size or shape connection members.

The frame system accommodates a wide variety of fabric or panel holders/retainers in the form of retaining strips, spacers, brackets, or the like as well as blanking plates and various fixings for different types of adjoining intermediate or end frame members. The frame system offers total flexibility in frame construction and fabric holding arrangements based around the careful design of common channel features through the range of different frame profiles.

All profiles can conveniently be formed by extrusion and cut to the desired length. The frame system does not require drilling of holes on site for fixing of adjoining frame members, thereby allowing reuse of the frame members and other components in different frame applications. Intermediate frame member can be positioned and repositioned with ease along the length of the channels. Different sizes and strengths of frames can be assembled with ease to provide the necessary structural strength and decorative/aesthetic properties.
