[0002] RELATED APPLICATIONS

[0003] This application derives priority from Australia patent application number 2024900496 filed on 28 February 2024 with WIPO DAS code 0FF9 incorporated herein by reference.

[0004] TECHNICAL FIELD

[0005] Described herein is a framing system, related items, kitsets and methods of assembly. More specifically, described herein is framing system comprising shaped extrusions fixingly cooperating with couplings, the couplings configured to couple together the shaped extrusions or a part thereof along with related items, kitsets and methods of assembly.

[0006] BACKGROUND

[0007] Framing systems are widely used in the manufacture of structural items such as furniture and shelving.

[0008] Existing framing systems typically comprise framing members that are generally elongated and which are designed to provide structure to the overall item. These framing members are typically welded together or instead, fastened together using screws, bolts, nuts and the like.

[0009] Where welding is used, the items are generally shipped in their finished form which may not be practical for shipping since the finished form is often bulky and with a void volume.

[0010] Where fastening is used, the parts may be flat packed and shipped in a compact form which is preferable for shipping to reduce associated costs. The consumer however must assemble the item on delivery which can be complicated for those unfamiliar with assembling such items and the techniques used. Special tools may be required. Special preparation may also be required to assist the consumer such as use of predrilled holes for the consumer to locate and connect a screw for example. The more complex the assembly, the more likelihood there is of product defects, breakages, returns and consumers having less interest in purchasing the item.

[0011] Flat packing and simple assembly may be favourable to both manufacturer and consumer alike if done well, as evidenced by the success of the Ikea™ brand and their products as one example. One drawback of products like those marketed by Ikea™ is that they are generally directed to producing one item of one prescribed size and shape e.g. a set of cube shelving of a 1x4 or 2x4 matrix. The consumer has no ability to change the size and shape of the item during assembly or, if consumer change is allowed for, this is generally restricted in nature.

[0012] One prior publication KR20230009701A describes a frame connector for modular furniture. The connector comprises an extrusion coupled to a polygonal block via a coupling. The coupling in this case has an elongated form with a head end, straight section, inclined section and threaded opposing end. The threaded head end threadingly engages a threaded opening on the polygonal block. The remainder of the coupling is captured inside the extrusion by a cam that engages the head end and a pressure fixing part or washer that sits between the inclined section and the extrusion wall and which interference fits the coupling and extrusion. Rotation of the polygonal block relative to the extrusion is prevented by a protrusion on the polygonal block face that keys with a similar shape in the extrusion interior. A disadvantage of this coupling is the need for an extra bespoke part (the pressure fixing part). Further, if the tolerances of the bolt inclined face and pressure fixing part and extrusion are not exact, there may be issues assembling the parts together.

[0013] Another prior publication US 2014 / 0241794A1 describes a connection for assembly of display stands comprising a bar member and a polygonal connector. The system requires a specific plug device and a socket device. The bar(s) to be coupled have a common and open crosssection interior. The plug or socket devices are inserted into the end of the bar and used to couple the bar and connector. A disadvantage of this system is the need to use bespoke plug and socket parts that require relatively high tolerance moulding and which, when being assembled, together may not align easily owing the varying cross-section of car or shape of connector.

[0014] It may be useful to provide an alternative framing system, related items, kitsets and methods of assembly that may be flat pack shipped, and coupled together in a variety of size and shape forms at least partially if not fully as prescribed by the consumer and not the manufacturer or retailer, or at least to provide the consumer with a choice.

[0015] Further aspects and advantages of the framing system, related items, kitsets and methods of assembly will become apparent from the ensuing description that is given by way of example only. SUMMARY

[0041] DETAILED DESCRIPTION

[0042] As noted above, described herein is framing system comprising shaped extrusions fixingly cooperating with couplings, the couplings configured to couple together the shaped extrusions or a part thereof along with related items, kitsets and methods of assembly.

[0043] For the purposes of this specification, the term 'about' or 'approximately' or 'substantially' and grammatical variations thereof mean a quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by as much as 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% to a reference quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length.

[0044] The term 'comprise1and grammatical variations thereof shall have an inclusive meaning - i.e. that it will be taken to mean an inclusion of not only the listed components it directly references, but also other non-specified components or elements.

[0045] A Framing System

[0046] In a first aspect, there is provided a framing system comprising: shaped extrusions comprising internal ports, the internal ports configured to fixingly cooperate with couplings; couplings configured to loosely fit or snug fit into one of the internal ports of the shaped extrusions; and fixing members configured to fix the couplings within the internal ports of the shaped extrusions, the fixing members configured to couple an end only of the couplings inside the internal ports; wherein the framing system is configured to provide a structural framework to provide structure, bracing and shape to an item manufactured from the framing system.

[0047] Framing

[0048] In one example, the structural framework assembled from the framing system may have a grid or matrix shape. Varying configurations may be possible and a grid or matrix shape should not be seen as limiting.

[0049] The framing system may be manufactured from structural or semi-structural materials e.g. aluminium or plastic shaped extrusions.

[0050] Shaped extrusions

[0051] The shaped extrusions may have an elongated form.

[0052] The shaped extrusions may have a longitudinal axis and opposing ends.

[0053] The shaped extrusions may have a generally consistent cross-section shape along the longitudinal axis of the shaped extrusions.

[0054] The shaped extrusions may have a varying longitudinal length.

[0055] A shaped extrusion may be formed from a die.

[0056] The shaped extrusions may have a uniform cross-section shape in a plane perpendicular to the longitudinal axis. The cross-section shape may have a generally square, triangular, circular, semi-circular, elliptical, rectangular or other polygonal exterior shape.

[0057] A shaped extrusion may have an external structure, internal structure and the internal ports may be located inside the external structure and amongst the internal structure.

[0058] The external structure may define the overall cross-section shape of a shaped extrusion and may have a smooth exterior face and a shaped interior face.

[0059] The internal structure may link a shaped interior face or part thereof to another shaped interior face or part thereof. The internal structure may be relatively thinner than the external structure. The internal structure may be termed webbing. The internal ports may be void spaces in the shaped extrusions. The internal port sides or void space edges may be bounded by: a shaped interior face or part thereof of the external structure; an internal structure or part thereof; both a shaped interior face or part thereof of the external structure and an internal structure or part thereof;

[0060] The internal ports may be shaped to complement a coupling shape or part thereof and are described more below. The internal ports may be circular, semi-circular, square or other polygonal shape.

[0061] Internal ports

[0062] The internal ports of the framing system may connect an internal void space or spaces inside the shaped extrusion to the shaped extrusion exterior.

[0063] The internal ports of a shaped extrusion may be accessed from an end or ends of the shaped extrusion. As noted above, these end internal ports may be shaped to complement a coupling or service line. The service line may alternatively be an electric cable or other cabling. The end internal port or ports may be generally circular although other shapes may be used.

[0064] The internal ports of a shaped extrusion may be accessed from a side or sides of the shaped extrusion. The side internal ports may be shaped to complement a coupling or service line. The service line may alternatively be an electric cable or other cabling. The side internal port or ports may be generally circular although other shapes may be used.

[0065] The internal ports of a shaped extrusion may be accessed from both the end or ends and the side or sides of the shaped extrusion.

[0066] The internal ports and couplings may have a common size to allow the couplings to snug fit into the internal port. For example, if the coupling is circular in cross-section, the internal port has a circular cross-section complementary to the coupling cross-section diameter. If the coupling instead has a polygonal cross-section shape, the internal port may have a complementary polygonal cross-section shape or may be circular in cross-section, the diameter of the internal port complementing a widest portion of the polygonal coupling cross-section shape. Complementary refers to the coupling and internal port fitting together in a snug fit or looser fit e.g. with a small amount of clearance e.g. less than 5% clearance. The coupling does not interference fit into the internal port. The coupling or internal port do not deform in order to fit together.

[0067] The internal ports may also be provided or used as ducting. The ducting may be fitted with lines such as electrical or fluid carrying cables, hoses or the like. The ducting may directly convey flowing substances e.g., water, oil, dry powders. The internal ports may comprise seals or sealant so as to be continuous in form at least through the interior of the internal port. This may be needed for example, to avoid unwanted flow of a fluid from the internal port or ducting described above.

[0068] Coupling

[0069] The internal ports and a coupling or the couplings may coordinate to couple together multiple shaped extrusions.

[0070] Coupling of the shaped extrusions may be releasable - that is the, shaped extrusions and couplings used may be coupled together in the structural framework and, after a period of time, uncoupled and disassembled in part or in full.

[0071] Once uncoupled, the shaped extrusions and couplings may be re-assembled together again in the same or a different configuration.

[0072] Coupling may be completed using a single tool being a screw driver or similar.

[0073] The term 'cooperation' or grammatical variations thereof as used herein, refers to the internal port(s) having a shape and form that corresponds to the couplings, e.g. a common circumference or width and a depth sufficient to receive a coupling therein.

[0074] The internal ports and couplings may have a common circumference. Alternatively, the internal ports may vary in geometry. For example, an internal port in the shaped extrusion configured for the at least one pin described further below, may have a different shape or size relative to an internal port configured for the elongated bolt or the mating cam. An internal port for the at least one pin may have a wider diameter than an internal port for the elongated bolt. An internal port for the mating cam may be wider in diameter than an internal port for the at least one pin or the elongated bolt.

[0075] The internal ports may have a depth sufficient to receive the couplings therein.

[0076] The internal port depth may extend fully along the longitudinal axis of the shaped extrusion. Elongated Bolt

[0077] The coupling may be an elongated bolt. The elongated bolt may have a substantially straight elongated form with a first end opposing a second end and a shaft, wherein the first end comprises a head, the head having a greater width than a width of the shaft and wherein the second end comprises a threaded portion.

[0078] The elongated bolt may be substantially cylindrical in cross-section with no inclined or declined outer surfaces relative to a longitudinal axis of the elongated bolt.

[0079] Bar

[0080] The coupling may be a polygonal cross-section bar.

[0081] Fixing Member

[0082] The fixing member may comprise an opening configured to engage with an end of the coupling.

[0083] The fixing member may be a cam and, the cam comprises a sloped surface therein that draws an end of the coupling into a housing of the mating cam.

[0084] The fixing member may be a fastener and the fastener or a part thereof directly engages the coupling or a part thereof.

[0085] The fastener may engage an indentation in the coupling.

[0086] The fixing member may be configured to fit into an end or a side internal port of the shaped extrusions and, the coupling or a part thereof, is configured to fit into an opposite end internal port or an opposite side internal port corresponding to a location of the fixing member.

[0087] The elongated bolt and mating cam may be two separate parts that when engaged, act to couple together multiple shaped extrusions.

[0088] In one example, one shaped extrusion may be coupled to a further shaped extrusion via one elongated bolt and one mating cam. Alternatively, two shaped extrusions may be coupled via two or more elongated bolts and mating cams. Reference to a single elongated bolt and mating cam in the description below should not be seen as limiting - multiple elongated bolts and mating cams may be used in lieu of a single connection for example, to increase the coupling strength.

[0089] The elongated bolt may have an elongated form with a first end opposing a second end and a shaft.

[0090] The first end may comprise a head. The head may have a greater width than a width of the shaft.

[0091] The second end may comprise a threaded portion.

[0092] The mating cam may comprise an opening configured to engage with the first end of the elongated bolt.

[0093] The mating cam may comprise a sloped surface. The sloped surface may be inside or scribed into an exterior volume of the mating cam. The sloped surface may act to draw the head of the first end of the elongated bolt into the exterior volume or interior of the mating cam.

[0094] The sloped surface of the mating cam may be eccentric to, or orthogonal to, a longitudinal axis of the elongated bolt.

[0095] Movement of the head of the elongated bolt along the sloped surface of the mating cam may be driven by rotating the mating cam. Rotating of the mating cam may be configured to be driven via a hand tool e.g. a screwdriver, cooperating with an opening in the mating cam.

[0096] The couplings in this example may be in a 90 degree arrangement with the mating cam located in a direction orthogonal to the longitudinal axis of the elongated bolt. The elongated bolt may comprise a swivel or other connector allowing the elongated bolt longitudinal axis to bend or rotate and therefore allow for angled relationships from 0 degrees or parallel to the longitudinal axis through to 90 degrees or orthogonal to the longitudinal axis of the elongated bolt.

[0097] The mating cam may be configured to fit into an end or a side internal port of the shaped extrusions. The elongated bolt may be configured to fit into an opposite end internal port or an opposite side internal port corresponding to a location of the mating cam.

[0098] The second end of the elongated bolt may engage a first shaped extrusion and the first end of the elongated bolt may engage a second shaped extrusion. The second end of the elongated bolt may threadingly engage the first shaped extrusion.

[0099] Coupling Ends The coupling may comprise a first end and a second end and, the first end of the coupling threadingly engages a first shaped extrusion and the second end of the coupling engages a second shaped extrusion.

[0100] Pin

[0101] The framing system may further comprise at least one pin, the pin configured to prevent relative rotation between the coupling and the extrusion.

[0102] The at least one pin may have an elongated form.

[0103] The at least one pin may have a generally common cross-section shape along a longitudinal length of the at least one pin.

[0104] A central portion of the longitudinal length of the at least one pin may comprise a rib or ring about a circumference of the at least one pin. The rib or ring may extend at least partly proud of an exterior surface of the at least one pin. The rib or ring may act as a stop to movement of the at least one pin into the internal ports of the shaped extrusions.

[0105] The at least one pin may be inserted into the internal ports of the shaped extrusions. The at least one pin may be inserted into an end internal port or a side internal port of the shaped extrusion.

[0106] The at least one pin may be inserted into at least one internal port eccentric to the internal port to which the coupling is located within.

[0107] The at least one pin may be located adjacent to the elongated bolt and the mating cam so that a coupled first shaped extrusion may have two points of interference with an abutting second shaped extrusion. Relative rotational movement in this example may be restricted or prevented between the first shaped extrusion and the second shaped extrusion.

[0108] Releasable Coupling

[0109] The shaped extrusions and the couplings may be releasably coupled together.

[0110] Connector Node

[0111] The framing system may further comprise a connector node. The connector node may comprise multiple faces. The connector node may be configured to couple together multiple shaped extrusions about the multiple faces. Each of the multiple faces may be located at varying angles so as to allow for varying orientations of shaped extrusion positioning relative to one another.

[0112] The connector node may have shapes such as cuboid, spherical, hexagonal, octagonal, or other polygonal geometries. The connector node may have multiple faces, the multiple faces have varying orientations.

[0113] A connector node may comprise openings configured to be used to couple one side of face or a connector node to a shaped extrusion and another side or face of the connector node and opening therein used to couple the connector node to a further shaped extrusion or shaped extrusions. As noted, the connector node may be configured to couple together multiple shaped extrusions. Examples are described further in terms of one shaped extrusion connected to one other shaped extrusion via one connector node but it should be noted that through varying size and geometry it may be possible to couple three or more shaped extrusions to one connector node.

[0114] Coupling via the connector node may be via a variety of faces on the connector node. A connector mode may comprise multiple faces. Each face may be at varying angles. This may be to allow shaped extrusions to be coupled at a variety of angels to one another. For example, the multiple faces may be position or configured to allow shaped extrusions to be coupled together: orthogonally or offset at an angle. Where offset, the angle may be at a regular angle e.g. 0-180, or 10 to 170 degree, or 30 to 150 degree, or 30 to 120 degree offset. The relative angle between shaped extrusions may be from 30, or 45, or 60, or 75 degrees as measured from the longitudinal axis of each shaped extrusion. As noted or implied above, each of the multiple faces may be located at varying angles so as to allow for varying orientations of shaped extrusion positioning relative to one another.

[0115] The openings described above may act in a similar manner to the internal ports described above used in the shaped extrusions. In the case of a connector node the openings may be located in one or on each side of a connector node. The openings may cooperate with the couplings described above to couple the connector node to the shaped extrusions. One face of the connector node may for example couple to a first shaped extrusion and another face of the connector node may be used to couple to another shaped extrusion.

[0116] Non-rotating coupling may be achieved through use of an adjoining opening in the connector node face configured to receive a pin therein. The pin may also be received in an opposing end of the shaped extrusion. The two couplings (elongated bolt, mating cam and pin) providing two point of interference and acting to restrict or prevent rotation of the shaped extrusion relative to the connector node.

[0117] Connector nodes may be manufactured from a rigid material such as a metal or metal alloy and shaped or moulded to the desired form.

[0118] Bracing

[0119] Optionally, bracing may be used to provide additional rigidity and strength to the framing system.

[0120] Bracing may be fitted once the framing system and / or furniture item is assembled. Bracing may be fitted during assembly of the framing system and / or furniture item.

[0121] Bracing may take the form of elongated struts, connectors, lines, cables and so on. Typically bracing may have an elongated shape with opposing ends. Bracing may take the form of a cable with crimped lugs. Alternatively, the bracing may take the form of flat or round rods manufactured from metal or alloy.

[0122] The bracing may be configured to provide rigidity in one or more planes of movement to the framing system once assembled.

[0123] Bracing may be fitted to the framing system shaped extrusions.

[0124] Bracing may be fitted to the framing system once assembled in a direction coincident with a longitudinal axis of the shaped extrusions.

[0125] Bracing may be fitted to the framing system once assembled in a direction offset from a longitudinal axis of the shaped extrusions.

[0126] Bracing may be attached to the framing system shaped extrusions once assembled in a direction diagonal to a longitudinal axis of the shaped extrusions.

[0127] Bracing may be coupled to the shaped extrusions. Coupling may be via one or more of the above described couplings or via other fasteners such as screws. Bracing may be coupled to a shaped extrusion or to a connector node or connector nodes if used.

[0128] External Couplings

[0129] In one example, one or more of the exterior faces or exterior sides of a shaped extrusion may comprise an exterior coupling or exterior couplings. The coupling or couplings may be clips or other shaped members configured to couple to and retain alongside the shaped member, a line or cable. The clips may for example have two opposing resilient arms or jaws that elastically deform to receive and retain a line therein. The exterior coupling may releasably couple the line to the shaped extrusion. The line or cable may be for a service such as a power cable, telecommunications cable, hose or fluid line and so on.

[0131] In a second aspect, there is provided an item of furniture comprising a framing system, the item of furniture comprising: a framing system substantially as described above; and one or more related furniture parts.

[0132] The framing system may be assembled to form an item of furniture.

[0133] The one or more related furniture parts may comprises glass, bench tops, drawer facings, shelves and so on.

[0134] Furniture Parts

[0135] The furniture parts noted may be of a variety of forms comprising but not limited to: table tops, shelving, wall materials, cube units, door units, seating materials, bases and so on.

[0136] The furniture parts may be manufactured from a variety of materials common to such items e.g. melamine board, safety glass, polycarbonate materials, plastic materials, sheet metals, cushioning materials and so on.

[0137] Whilst not strictly furniture, the framing system may be used to locate within insulating material (sound or heat) so that the framing system may act as an insulating wall or ceiling feature.

[0138] Further examples of items that are not strictly furniture parts but where the framing system may be used comprise use in engineering and construction frames, safety and materials handling, windows and doors, fences and gates, pipelines and so on. Reference to furniture, furniture items and furniture parts should not be seen as limiting the applications to which the framing system may be used. Kitset

[0194] EXAMPLE 1

[0195] In this example the basic framing system 1 is described with reference to Figure 1, Figure 2 and Figure 3. Figure 1 shows a variety of shaped extrusions 10, couplings 30 in the form of an elongated bolt 40, a mating cam 50 and a pin 60 in perspective view with the different parts in a disassembled orientation. The shaped extrusions 10 have internal ports 13.

[0196] Figure 2 and Figure 3 show a variety of shaped extrusions 10, elongated bolt 40, a mating cam 50 and pins 60 in perspective view with the different parts in an exploded assembled orientation.

[0197] As shown, the shaped extrusions 10 comprise internal ports 13 that cooperate with the couplings 30 shown (elongated bolt 40, mating cam 50 or pin 60) e.g. common diameter and a depth at least sufficient to receive the coupling 30 therein.

[0198] Figure 2 and Figure 3 show how the couplings 40, 50, 60 may be arranged to couple together the shaped extrusions 10 or a part thereof.

[0199] The shaped extrusions 10 in more detail comprise an elongated form with a longitudinal length 11 and opposing ends. As shown, the shaped extrusions 10 have a consistent cross-section shape along the longitudinal axis of the shaped extrusions 10 typical of an extruded part. The shaped extrusions 10 have a variety of longitudinal length 11 (shortened and largely common lengths shown in Figures 1-3 for ease of description). Being extrusions, the shaped extrusion 10 length may be of infinite length.

[0200] The shaped extrusions 10 cross-section shape in a plane perpendicular to the longitudinal axis is uniform and may be of a variety of shapes like those illustrated e.g. square, triangular or circular.

[0201] Each shaped extrusion 10 as shown has an external structure and an internal structure 14. The internal ports 13 open to through the external structure and into the internal structure 14.

[0202] The internal ports 13 as shown are round with a diameter 17 to complement a coupling 40, 50, 60 shape or part thereof. The internal ports 13 may be end internal ports 15 or side internal ports 16.

[0203] The elongated bolt 40 and mating cam 50 as shown are separate parts The elongated bolt 40 has an elongated form with opposing ends 42, 43, and a shaft 44 with a longitudinal axis 41. One end 42 comprises a head 45. The head 45 may have a greater width than a width of the shaft 44. The opposing end 43 may comprise a threaded portion 46.

[0204] The mating cam 50 may comprise an opening (not shown in Figures 1-3) in the mating cam side that is configured to engage with the elongated bolt 40 head 45.

[0205] The mating cam 50 comprises a sloped surface (not shown in Figures 1-3) that draws the elongated bolt 40 head 45 into the housing (not shown in Figures 1-3) of the mating cam 50.

[0206] A hand tool (not shown) may cooperate with an opening 55 in the mating cam 50 to allow movement of the hand tool to urge rotation of the mating cam 50 to cause coupling (described further below).

[0207] The mating cam 50 as shown fits into a side internal port 16 of the shaped extrusion 10 although, could be fitted to an end internal port 15 if desired and if the shaped extrusion 10 has an internal port 13 shaped to receive the mating cam 50.

[0208] The elongated bolt 40 as shown fits into an end internal port 15 of the shaped extrusion 10 although, could be fitted to a side internal port 16 if desired and if the shaped extrusion 10 has an internal port 13 shaped to receive the elongated bolt 40.

[0209] The pin 60 as shown has an elongated form with a slender cross-section shape along a longitudinal length 61. A central portion 62 of the pin 60 has a ring 63 about the pin 60 circumference that extends proud of an exterior surface 64 of the pin 60. The ring 63 acts as a stop to movement of the pin 60 into the internal port(s) 13 of the shaped extrusions 10 so the pins only push into the internal ports 13 to the ring 63.

[0210] The pin 60 may be located adjacent to the elongated bolt 40 as shown in Figure 2 so that a coupled first shaped extrusion 10 has two points of interference with an abutting second shaped extrusion 10. Relative rotational movement is prevented between the extrusions 10.

[0211] EXAMPLE 2

[0212] The way the parts couple is shown in more detail in Figure 4 and in Figure 5. Figure 4 and Figure 5 illustrate cross-section side elevation views of an intersection between shaped extrusions 10 in a coupled position with an elongated bolt 40 located in an end internal port 15 and locked in place by a mating cam 50 that has been rotated about direction 54 which causes the camp to engage with and drawn in tension direction 47 the head 45 of the elongated bolt at the first end 42. The elongated bolt 40 second end 43 comprises a thread portion 46 and this threaded portion 46 is threadingly engaged to a side internal port 16 of a shaped extrusion 10.

[0213] Coupling as noted above may be releasable - that is the, shaped extrusions 10 and couplings 40, 50 used may be coupled together to form the structural framework and, after a period of time, uncoupled and disassembled in part or in full. Uncoupling may be achieved by reversing the rotation direction of the mating cam 54 which releases tension on the elongated bolt 40 head 45. Once uncoupled, the shaped extrusions 10 and couplings 30 may be re-assembled together again in the same or a different configuration.

[0214] Coupling may be completed using a single tool being a screw driver or similar that urges rotation of the mating cam 50. The cam surface pulls on the elongated bolt 40 head 45 and causes a tension force along the elongated bolt 40 longitudinal axis.

[0215] The internal ports 13 have a depth sufficient to receive the couplings 30 therein. The internal port 13 depth may extend fully along the longitudinal axis of the shaped extrusion 10.

[0216] The couplings 40, 50 in this example may be in a 90 degree arrangement with the mating cam 50 located in a direction orthogonal to the longitudinal axis of the elongated bolt 40. A swivel or other connector could be used to vary this angle from 90 degrees.

[0217] EXAMPLE 3

[0218] As noted above, the framing system 1 may comprise a connector node 70 or connector nodes 70. Figure 6 and Figure 7 show the connector node 70 in more detail and how they may be used. Figure 6 shows perspective views of three geometries of connector node 70. Figure 7 shows partly assembled framing systems 1 and furniture item 90 incorporating the connector nodes 70.

[0219] As shown in these Figures, the connector node 70 may have various shapes such as cuboid or other polygonal geometries. The connector nodes 70 have multiple faces 71 and the multiple faces 71 have varying orientations. The faces 71 have openings 72 configured to be used to couple one side or face 71 of a connector node 70 to a shaped extrusion 10 and another side or face 71 of the connector node 70 and opening 72 therein used to couple the connector node 70 to a further shaped extrusion 10 or shaped extrusions 10.

[0220] Faces 71 of the connector nodes 70 may be at varying angles to allow shaped extrusions 10 to be coupled at a variety of angles relative to one another. The openings 72 in the connector nodes 70 act in a similar manner to the internal ports 13 described above used in the shaped extrusions 10. The openings 72 cooperate with the couplings 30 described above to couple the connector node 70 to the shaped extrusions 10.

[0221] Non-rotating coupling may be achieved through use of an adjoining opening 72 in the connector node 70 face 71 configured to receive a pin 60 therein. The pin 60 may also be received in an opposing end of the shaped extrusion 10. The two couplings (elongated bolt 40, mating cam 50 and pin 60) providing two points of interference and acting to restrict or prevent rotation of the shaped extrusion 10 relative to the connector node 70.

[0222] EXAMPLE 4

[0223] To further demonstrate the framing system 1 and structural framework 2 produced, Figure 8 is provided illustrating a partially assembled framing system 1 using shaped extrusions 10 having internal ports 13 and, in some cases, side internal ports 16. Couplings 30 as shown, in this Figure as elongated bolts 40 and cams 50. Pins 60 are also used in the example illustrated to provide a stop to rotational relative movement of one shaped extrusion 10 relative to another shaped extrusion 10. As shown in Figure 8, corners of the shaped extrusions 10 may be mitred and the couplings 30 adjusted to suit the corner angle (shown as a 90 degree bend in Figure 8). Also shown is the way a foot 130 may be integrated into the design as well e.g. threaded into an internal port 13 of a shaped extrusion 10.

[0224] EXAMPLE 5

[0225] The couplings 30 may as noted above take varying forms. Figure 9 illustrates a kit of parts for a framing system 1 comprising couplings 30 in the form of elongated bolts 40 or plate or bar shaped couplings 120 along with other parts already described including shaped extrusions 10 and connector nodes 70. The plate shaped couplings 120 may take a variety of shapes and forms as illustrated including, for example, indents 121 shaped to received a grub screw 122 against and which locks the plate shaped coupling 120 in place. The plate shaped couplings 120 may further comprise a variety of ending shapes corresponding to the shaped extrusion 10 position to which the plate shaped coupling is coupled e.g. a hook ending or a notched ending 123, a round ending and so on. The plate shaped extrusions 120 may be straight or bent to suit an angle between shaped extrusions 10. Figure 10 demonstrates a partly assembled framing system 1 using the parts shown in Figure 9, specifically using shaped extrusions 10, plate shaped couplings 120 comprising indents 121 and grub screws 122 fixing the plate shaped couplings 120 in the shaped extrusion 10 internal ports 13 be interference with the indents 121 in the plate shaped extrusions 120. Plate shaped couplings may be useful to prevent rotation between shaped extrusions in a manner that avoids use of pins 60 although, as illustrated, the framing system 1 may use a combination of varying coupling 30 types.

[0226] EXAMPLE 6

[0227] As noted elsewhere, the framing systems 1 described may be used to form items of furniture 90, the item of furniture comprising: a framing system as described above 1 and one or more related furniture parts. The furniture parts may be table tops, shelving, wall materials, cube units, door units, seating materials, bases and so on. The furniture items 90 may be tables, shelving units, coffee tables, seats and so on.

[0228] Figures 11 to 18 illustrate examples of furniture items 90 made using the framing system 1 described specifically:

[0231] Figure 13 illustrates an entertainment unit made up from square shaped extrusions 10 coupled to varying shapes of shelving (furniture part) to form the overall entertainment unit (furniture item 90). In this example, the shaped extrusions may be used for the base only or may be hidden within a veneer, the shaped extrusions providing structure to form the entertainment unit sides, top and base along with internal walls (optional);

[0233] Figure 15 shows an alternative shelving unit comprising multiple spaced apart tall shaped extrusions 10 and shelving (furniture parts) to form the shelving unit 90 (furniture item). The shelving unit 90 in this example may comprise bracing 80, shown in this case as diagonal directed elongated slender members. The bracing 80 may be used to provide additional stability to the furniture item 90;

[0234] Figure 16 shows a further alternative shelving unit that may used to form a wardrobe having hanging members, drawers and shelving of varying depth. Again in this example, bracing 80 may be used intermediate shaped extrusions 10;

[0235] Figure 17 illustrates a coffee table assembled using the framing system 1 comprising square shaped extrusions 10 and connection nodes 70 described elsewhere along with a glass table top (furniture part) to form the furniture item 90; and

[0236] Figure 18 illustrates a partial view of a table assembled using the framing system 1 comprising varying shaped extrusions 10 along with a solid table top (furniture part) to form the furniture item 90.

[0237] EXAMPLE 7

[0238] In this example a set of instructions are provided for assembly of a framing system 1 representing one method of assembly.

[0239] • Select two square cross-section shaped extrusions 10 of lengths A and B that may be used to form one 90 degree tee connection.

[0240] • Both shaped extrusion 10 length A and length B may contain the same internal crosssection shape 12. Both 10 may have internal ports 13 configured to accept at least one elongated bolt 40 and optionally also at least one pin 60 within an end of the shaped extrusion 10 (end internal port(s) 15). Shaped extrusion 10 of length A. may also have a side internal port(s) 16 configured to accept the opposite end (threaded) 43 of the elongated bolt 40 and an internal port that accepts an opposite end of the pin 60 if used. This pair of the elongated bolt 40 and pin 60 have a required distance from the other to match the same distances in the internal ports 13 of the shaped extrusion 10 of length B.

[0241] • To couple the shaped extrusions 10, screw in the elongated bolt 40 threaded end 43 to the shaped extrusion 10 of length A threaded opening 13,15,16. Then push the pin 60 into the internal port 13, 15, 16 in the side of shaped extrusion 10 of length A.

[0242] • Take the shaped extrusion 10 of length B and slide the end internal ports 13, 15 over the elongated bolt 40 head 45 end 42 and exposed end of the pin 60 until the end of shaped extrusion 10 of length B touches against the side of shaped extrusion 10 of length A.

[0243] • An internal port (side port) 13, 16 for the mating cam 50 is bored a corresponding distance from the end of shaped extrusion 10 of length B to meet up with a rebate step in the elongated bolt 40 head 45.

[0244] • The side internal port 13, 16 may be drilled slightly deeper than the mating cam 50 into the side face of shaped extrusion 10 of length B to allow the mating cam 50 to drop fully into the side internal port 13, 16.

[0245] • Drop the mating cam 50 into this side internal port 13, 16 with an arrow 55 on the mating cam 50 outer face facing the shaped extrusion 10 of length A.

[0246] • Rotate the mating cam 50 clockwise to cause the elongated bolt 40 head 45 and mating cam 50 to engage. As rotation continues, the mating cam 50 will draw the elongated bolt 40 head 45 into the mating cam 50 interior causing tightening of shaped extrusion 10 of length B towards shaped extrusion 10 of length A, creating a firm connection.
