Description

"Modular wall panel"

Technical Field

[0001] The present disclosure relates to modular wall panels that can be configured with one another to create a wall or partition.

Background

[0002] In some buildings, it is desirable to reconfigure partitions and walls. For example a floor of an office building may be leased to a tenant and the tenant may require a particular configuration to suit their business needs. For example, the tenant may have particular requirements for meeting rooms, enclosed offices, workstations, partitions etc.

[0003] To accommodate the needs of the tenant, an office building may be "fitted" for a tenant. This may include removing or inserting walls, partitions, lighting, heating ventilation and air conditioning. This may also include wiring the office space for power and communications (including telephone and data networks). This may involve substantial costs including labour costs of having specialist technicians (such as electricians) laying out electrical cabling.

[0004] Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application.

[0005] Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. Summary

[0006] A modular wall panel comprising a panel body and a first electrical connector. The panel body has a first interface region to secure the modular wall panel with an adjacent modular wall panel, wherein the first interface region includes at least one interlock protrusion to engage with a respective interface region of the adjacent modular wall panel. The first electrical connector at the first interface region forms an electrical connection with a respective electrical connector of the adjacent wall panel, wherein the first electrical connector is an electrical interface for at least part of an electrical circuit associated with the modular wall panel.

[0007] Therefore the modular wall panel may be secured to adjacent modular wall panels to provide a physical barrier as well as been electrically connected to allow power and/or communications to be transferred from one modular wall panel to another.

[0008] In modular wall panel, the panel body may further comprise a second interface region to secure the modular wall panel with the, or further, adjacent modular wall panel. The second interface region includes at least one interlock recess to engage with a respective interlock protrusion of a respective interface region of the, or further, adjacent modular wall panel. The modular wall panel may further comprise a second electrical connector at the second interface region to form an electrical connection with a respective electrical connector of the, or further, adjacent wall panel, wherein the second electrical connector is also an electrical interface for at least part of the, or another, electrical circuit associated with the modular wall panel.

[0009] In the modular wall panel, the second electrical connector may be at the at least one interlock recess.

This may assist alignment and centring of connected adjacent panels.

[0014] The interlock protrusions may be part of a locking mechanism, wherein the locking mechanism further comprises a rotatable spindle, wherein selective rotation of the spindle configures the interlock protrusions to extend and retract in respective extended and retracted configurations.

[0015] The rotatable spindle may be configured to receive a removable crank such that the crank assists selective rotation of the spindle.

[0016] In some examples of the modular wall panel, one or more of the interlock protrusion may be fixed relative to the panel body. [0017] The panel body of the modular wall panel may comprises: two opposite and substantially rectangular planar wall surfaces; and four side surfaces that extend between respective adjacent edges of the rectangular planar wall surfaces, wherein the first interface region and/or the second interface region are positioned on one or more of the four side surfaces.

[0018] At least one of the four side surfaces may comprise: a first surface portion having the first interface region; and a second surface portion having the second interface region. To secure the modular wall panel 3 to the adjacent modular wall panel, the first surface portion may be positioned to face a respective second surface portion of the adjacent modular wall panel and the second surface portion may be positioned to face a respective first surface portion of the adjacent modular wall panel.

[0019] The first and second surface portions may be asymmetrically positioned along a length of the side.

[0020] The panel body may include a plurality of the first interface region and a plurality of second interface regions, wherein each of the four side surfaces includes one of the first interface region and/or the second interface region.

[0021] The modular wall panel may comprise an internal frame that has a plurality of tubular members to support the panel body, wherein at least one of the interlock protrusions extend from at least one of the tubular members.

[0023] The plurality of tubular members of the internal frame may be in a hash shaped grid such that at least a pair of tubular members extend to each side, wherein each of the pair of tubular members include: a first tubular member wherein one of the interlock protrusions extends from the first tubular member; and a second tubular member wherein one of the interlock recess is inside the second tubular member.

[0024] In some examples, the plurality of tubular members of the internal frame may form a substantially square or rectangular shape at the perimeter of the modular wall panel.

[0025] The modular wall panel may further comprise at least one socket wherein the socket is an electrical interface between at least part of the electrical circuit to an electrical device.

[0026] The modular wall panel may further comprise electrical wiring between one or more electrical connectors and/or sockets. The electrical circuit may comprise one or more of electrical power, telephone, or data communications circuits.

Description of Embodiments

[0061] A modular wall system 1 comprising a plurality of modular wall panels 3 is illustrated in Fig. 1, which in this example shows three modular wall panels 3, 103, 203 secured to an adjacent modular wall panel 103, 203.

[0062] The modular wall panel 3, as shown in Figs. 1 and 2(c), includes a panel body 5 having a first interface region 7 to secure the panel 3 with a first adjacent modular wall panel 103. The first interface region 7 includes at least one interlock protrusion 9 to engage with a respective interface region 115 of the first adjacent modular wall panel 103. A first electrical connector 11 is at the first interface region 7 to form an electrical connection with a respective electrical connector 119 of the first adjacent wall panel 103, wherein the first electrical connector 11 is an electrical interface for at least part of an electrical circuit 13 associated with the modular wall panel (3).

[0063] The modular wall panel 3 may also include a second interface region 15 to secure the modular wall panel 3 with an adjacent modular wall panel 103, 203. The second interface region 15 includes at least one interlock recess 17 to engage with a respective interlock protrusion 109, 209 of a respective interface 107, 207 of the adjacent modular wall panel 103, 203. A second electrical connector 19 is at the second interface region 15 to form an electrical connection with a respective electrical connector 111, 211 of the adjacent wall panel 103, 203. The second electrical connector 103, 203 is also an electrical interface for at least part of, or another, electrical circuit 13 associated with the modular wall panel 3.

[0064] The modular wall panel 3 may have multiple first and second interface regions 7, 15 so that the modular wall panel 3 can be secured to multiple adjacent modular wall panels 103, 203. In this example, the modular wall panel 3 is rectangular and adjacent modular wall panels 103, 203 may be secured to each of the four sides 25.

[0065] The system 1 of modular wall panels may achieve two functions. Firstly as a wall panel to partition or segment a space, such as an office. Secondly, to provide an electrical circuit, or network of electrical circuits. Such electrical circuits may include one or more circuits for power and communications. This system may be advantageous for ease of use and simplicity as assembling the system of modular wall panels 3 may provide structure as well as power and communications. That is, this system may be "plug and play" without having an expert electrician installing and running wiring as a separate step, or connecting wires with wire taps separately.

[0066] In some examples, this may allow an operator to reconfigure a room or office space without having to engage the services of multiple specialists, such as a builder, an electrician and/or a communications technician. [0067] In this description, the features of adjacent modular wall panels 103, 203 that are similar or the same as those of the modular wall panel 3 are given the " 100" and "200" prefix. Details of an example modular wall panel 3 will now be described in detail.

Structure of the modular wall panel 3

Internal frame 21

[0068] Referring to Figs. 2 and 3 to 7, the modular wall panel 3 has an internal frame 21 that provides structural rigidity and support for the modular wall panel 3 and system 1. The internal frame 21 may include a plurality of tubular members 23 to support the panel body 5.

[0069] The tubular members 23 may be configured to receive, at least in part, one or more of the interlock protrusions 9, 109, 209. This may include the interlock protrusion 9 of the modular wall panel 3 extending from the tubular members 23 of the frame 21.

[0070] The one interlock recess 17, or part thereof, may be inside one of the tubular members 23 such that an interlock protrusion 109, 209 from an adjacent modular wall panel 103, 203 extends into the tubular member(s) 23.

[0071] In the illustrated example, the tubular members include rectangular hollow sections (RHS) that are joined together to form a hashed shaped grid. Accordingly, each side 25 of the square modular wall panel 3 includes a first tubular member 27 and a second tubular member 29. As will be discussed in further detailed below, the first tubular member 27 may have one of the interlock protrusions 9 extending therefrom and the second tubular member 29 may have, inside, the interlock recess 17.

[0072] The internal frame may be made of steel, aluminium, fibre reinforced plastics, or other suitable rigid material for building construction. In some examples, this may include RHS components welded, bonded, or otherwise joined together to form the internal frame 21.

Laminate, board and insulation of the modular wall panel

[0073] Referring to Figs. 3 to 7 the modular wall panel 3 may also include insulation 31, which may include acoustic insulation and/or thermal insulation. Examples of insulation include glass wool, wool, cellulose fibre, polyester and polystyrene. The insulation 31 may be positioned in the grid of the internal frame 21.

[0074] On opposite sides of the modular wall panel 3, there may be a planar surface board 33a, 33b. The board 33a, 33b, provides the surface to the modular wall panel 3 and may be of a lighter construction compared to the internal frame 21. This may allow the system 1 to be lighter than comparable systems. The board 33a, 33b may be constructed of drywall material, such as plasterboard.

[0075] In some examples, the modular wall panels 3 may be surfaced by another material, such as a laminate 35a, 35b. This may provide useful for providing a pleasing aesthetic appearance. For example, the laminate may include, or replicate, a wood surface. In some examples, this may include a painted surface. In yet other examples, this may include a fabric or cushion surface so that the surface may be used as a pin board.

Electrical connector 11, 19

[0076] An example of the first electrical connector 11 is illustrated in Fig. 8. In this example, the first electrical connector 11 is located, at least in part, at the interlock protrusion 9. The first electrical connector 11 may include a male plug 41, and where at least part of the first electrical connector 11 is located in a hollow 43 of the interlock protrusion 9. [0077] An example of the second electrical connector 19 is also illustrated in Fig. 8. In this example, the second electrical connector 19 is located, at least in part, at the interlock recess 17. The first electrical connector 11 may include a female plug 45, and where at least part of the second electrical connector 19 is located in a hollow 47 of the interlock recess 17.

[0078] As shown in Fig. 9, when the interlock protrusion 9 is received and engages with the interlock recess 117, 217 this may simultaneously cause mating of the male plug 41 and the female plug 45 so that the first electrical connector 11 of a modular wall panel 3 forms an electrical connection with a second electrical connector 119, 219 of the adjacent panel 103, 203.

[0079] The electrical connection with adjacent modular wall panels may include power and/or communications. In some examples, the first and second electrical connectors 11, 19 may be dedicated to either power or communications. In other examples, the electrical connectors 11, 19 may support both power and

communications. Since each modular panel 3, 103, 203 may have a plurality of first and second electrical connectors 11, 19, some connectors may be dedicated to power and others dedicated to communications.

[0080] Although the first electrical connector 11 described above includes a male plug 41, it is to be appreciated that the first electrical connector 11 may include a female plug and the second electrical connector 19 includes a male plug. In yet further examples, the plugs may include unisex plugs (for example, each connector may include matching electrical contacts).

[0081] Some alternative examples may include an induction connection between modular wall panels 3, 103, 203 to pass electrical power and or communications. This may advantageously reduce risks of an electrical short. Electrical circuit 13

[0082] The electrical circuit 13 associated with the modular wall panel 3 may include a power circuit and/or communication circuit. For example, this may include wiring that electrically connects the first electrical connector 11 to a second electrical connector 19 in the modular wall panel 3. This may allow power and/or data communications from one side 25 of the panel 3 to another side 25 of the panel.

[0083] In some examples, the electrical circuit may include a plurality of electrical circuits. For example, a dedicated power circuit, telephone circuit, and data

communications circuit.

[0084] In some examples, the modular wall panel 3 may also include one or more electrical switching means. For example, the switching means may detect the type of connection, voltage, current etc., received at the first electrical connector 11 and/or second electrical connector 19 and in response route the circuit to one or more other electrical connectors. For example, if the switching means detects 240 volts AC, this may be provided selectively to one or more electrical connectors specified for power. Alternatively if the switching means detects a telephony signals, this may be selectively be connected to other electrical connectors (or a telephony socket) of the modular wall panel 3. It is to be appreciated that the switching means may also be selectively configured by an operator to specify particular circuit paths between one or more of the electrical connectors 11, 19.

[0085] The modular wall panel 3, 103, 203 may further include one or more sockets 71 as illustrated in Figs. 14 and 17. The sockets 71 may an electrical interface between at least part of the electrical circuit 13 to an electrical device. In one example, the socket 71 may be a power socket and the electrical device may be a computer, monitor, desk lamp, battery charger, etc. In a further example, the socket 71 may include a communications socket used with RJ11 and 8P8C systems for telephone and network communications. The sockets 71 may be positioned on the planar surfaces such as on the boards 33a, 33b. The sockets 71 and the electrical connectors 11, 19 may be electrically connected by electrical wiring in the modular wall panel 3, 103, 203.

[0086] In some examples, an AC to DC voltage converter may be integrated in to the modular wall panel. For example, a DC output of 5 volts may be output via a USB socket on the wall panel 3, 103, 203.

Protrusions 9

[0087] The protrusions 9 may be selectively extended and retracted. This may allow ease of assembly of the modular wall system 1 as multiple modular wall panels 3, 103, 203 may be positioned in place, after which the respective protrusions 9, 109, 209 are extended such that the panels 3, 103, 203 are secured with one another. This may be advantageous for wall systems 1 that are installed such that the wall extends from the floor to the ceiling of the office, as the operator will not need to provide for a clearance at the top (or the sides) to allow the protrusions to slide in during assembly of the panels 3, 103, 203. This can be in contrast to protrusions 9 that are fixed.

[0088] The extendible protrusions will now be described with reference to Figs. 2, 10 to 12. Figs. 2(b), 10(a), 10(b) and 12(a) illustrate a modular wall panel with the interlock protrusions 9 in a retracted configuration, whereby the interlock protrusions 9 are retracted inside the tubular members (such as the first tubular member 27).

Accordingly when in the retracted configuration, the interlock protrusions 9 are configured to disengage with the respective interface regions 115, 215 of the adjacent modular wall panels 103, 203.

[0089] Figs. 2(c), 11(b) and 12(b) illustrate the protrusions 9 in an extended configuration. When in the extended configuration, the interlock protrusions 9 are configured to engage with the respective interface regions 115, 215 of an adjacent modular wall panel 103, 203. This engagement is illustrated in Fig. 1 where the interlock protrusions 9 are received and engaged with interlock recesses 117, 217 of the adjacent modular wall panels 103, 203. [0090] The extendible interlock protrusions 9 may include lock pins, such as the hollow lock pins shown in Fig. 8. The lock pins may be extended and retracted along a respective lock pin axis that coincides with the axis of the first tubular member 27 that slidingly receives the interlock protrusion 9.

[0091] The interlock protrusions 9 may be part of a locking mechanism 51, wherein the locking mechanism further comprises a rotatable spindle 53 as shown in Figs. 12(a) and 12(b). In one example, the rotatable spindle 53 may be linked to the interlock protrusion 9 by arms 55 such that selective rotation of the spindle 53 causes the interlock protrusions 9 to extend and retract. This may allow a user to selectively configure the interlock protrusions 9 to the extended and retracted configurations.

[0092] In other examples, the locking mechanism may include a rack and pinion system where the rack (such as a toothed bar) is moved by rotation of a pinion gear that, in turn, is driven by the spindle 53.

[0093] The rotatable spindle 53 may be configured to receive a removable crank 57. The spindle 53 may include a socket to receive the crank 57 and crank may assist selective rotation of the spindle 53.

Configuration of the modular wall panel

[0094] It is to be appreciated that the modular wall panel 3 may be of different sizes and configurations. It is to be appreciated that the modular wall system 1 may be assembled with different modular wall panels 3 to suit different needs. For example, modular wall panels 3 that are positioned to extend from the floor may have a base side configured to sit flush with the floor. In another example, modular wall panels for higher portions of the ceiling may be configured to interface with ceiling panels, and may be ducted to receive air from a heating ventilation and air conditioning system. In yet another example, some modular wall panels may be configured to receive shelves or cabinets, whilst others may be configured to receive monitors, picture frames, etc. [0095] In some examples, the modular panels for the periphery of the modular wall system 1 may be of a different size and configuration to ensure proper fit. For example, the system may comprise primarily of a "standardised size" modular panel of l x l metre. However, the room may not be dimensioned to within 1 metre units and therefore smaller modular panels may be assembled to the system 1 to cover gaps.

[0096] Referring to Figs. 2 to 7, one example of a modular wall panel 3 includes two opposite and substantially rectangular planar wall surfaces, such as those provided by boards 33 a, 33b. Four side surfaces 25 extend between the adjacent edges of the rectangular planar wall surfaces so that the wall panel 3 is substantially a rectangular prism. The side surface 25 includes a first interface region 7 and/or a second interface region 15.

[0097] In the illustrated example a side surface 25 includes both the first interface region 7 and the second interface region 15. Each side 25 has a first surface portion 61 having the first interface region 7, and a second surface portion 63 having the second interface region 15 as illustrated in Figs. 2(b) and 2(c). The first surface portion 61 and the second surface portion 63 may be asymmetrically positioned along a length of the side 25. As shown in Fig. 1, when the modular wall system is assembled, the first surface portion 61 is positioned to face the second surface portion 63, 163, 263 of an adjacent modular wall panel 103, 203, and the second surface portion 63 is positioned to face the first surface portion 61, 161, 261 of the adjacent modular wall panel 103, 203. This may allow the side surface 25 to abut and join with any other corresponding side surface 25 of the adjacent modular wall panel 103, 203. Thus in some examples, the modular wall panels 3, 103, 203 may not have a strict "top", "bottom", "left" and "right" sides, but instead each side 25 can be joined on any one of the four sides of an adjacent modular panel 3.

Configuring the modular wall system 1

[0098] Figs. 1 and 13 to 17 illustrate a modular wall system 1 that includes multiple modular wall panels 3, 103, 203. In one example, the modular wall panels 3, 103, 203 are substantially rectangular such that the panels are secured to each other in a grid to form a wall. This allows the panels to be used to create an office partition or wall of an office that may be easily scalable and reconfigurable. Advantageously, the modular wall system 1 may be easily assembled to provide not only a physical barrier but also power and communications.

[0099] An example of assembling the modular wall system 1 will now be described. Referring to Fig. 13, a first modular wall panel 3 may be positioned on the floor 80 with the interlock protrusions 9 in a retracted configuration. One or more adjacent modular panels 103, 203, also with respective interlock protrusions 9 in the retracted configuration, are then positioned adjacent to the first modular wall panel 3 such that the first interface region 7 of the first modular wall panel 3 faces the second interface region 115, 215 of the adjacent modular wall panels 103, 203. Similarly, the second interface region 15 of the first modular wall panel 3 faces the first interface regions 107, 207 of the adjacent modular wall panels 103, 203.

[0100] The crank 57 is then inserted into the socket of the spindle 53, and a user may then rotate the crank 57 to cause the interlock protrusions 9 of the first modular wall panel 3 to extend to the extended configuration. These interlock protrusions 9 therefore extends into, and engages with, the interlock recesses 117, 217 of the adjacent modular wall panels 103, 203, and therefore securing the modular wall panels 3, 103, 203 to one another. The crank 57 may then be removed, and if desired, used with one or more other modular wall panels 103, 203 to extend the respective interlock protrusions 109, 209. This process may be repeated as desired to erect the modular wall system 1.

[0101] After the modular wall panels 3, 103, 203 are secured, further accessories may be added as shown in Fig. 14. For example, shelves, desks, lamps, picture frames, computer 82, monitors, etc. may be mounted to parts of the modular wall panels 3, 103, 203. This may also include connecting power and communications to devices via sockets 71. This may also include connecting one or more of the modular wall panels 3, 103, 203 to the main power supply and communications hub. This may be via a socket 71 or through one or more of the electrical connectors 11, 19. [0102] It is to be appreciated that interlock protrusions 9 may not be required on all sides. For example, a bottom side of a modular wall panel 3 at the floor 80 may not require an interlock protrusion 9 as the floor may not have a corresponding recess. In such cases, the interlock protrusion 9 may be removed from the panel. Alternatively, that particular interlock protrusion 9 may be selectively retracted in the retracted configuration whilst the other interlock protrusions 9 are selectively extended.

[0103] To disassemble the modular wall system 1, the protrusions 9 may be selectively retracted to disengage adjacent modular wall panels 3, 103, 203 such that the wall panels may be removed.

Ceiling panels 85

[0104] Fig. 15 illustrates a modular ceiling panel 85 that may be used with the modular wall system 1. The ceiling panel 85 may include a corresponding first interface region 11 and/or second interface 15 region similar to the modular wall panels 3, 103, 203 so that the ceiling panels can be secured to adjacent ceiling panels and/or modular wall panels.

[0105] The ceiling panel 85 may have a similar system of electrical connectors 11, 19 associated with first and second interface regions 7, 15 to provide an electrical interface for an electrical circuit 13. In one example, this may include an electrical circuit including one or more light fittings 87 to provide light to a room. The ceiling panels may also allow power and communications to pass through similar to those of the modular wall panels 3.

[0106] The ceiling panel 85 may also include one or more HVAC (heating, ventilation and air conditioning) ducts 89 that may be fluidly connected to HVAC ducts of adjacent ceiling panels 85. The HVAC ducts assist in providing air flow into the room via ceiling vents 91 as illustrated in Fig. 17. [0107] It is to be appreciated that some examples of the modular wall panels 3 may also have HVAC ducts 89 and vents.

Office Pod 93

[0108] Figs. 16 and 17 illustrate an office pod 93 that includes a plurality of panels assembled and secured together. This may include a plurality of modular wall panels 3 of the modular wall system 1 to form wall so an office and a plurality of ceiling panels 85.

[0109] The office pod 93 may allow ease of fabrication, transportation and erection of the office pod. For example, a customer may specify an office and panels are selected to meet those specifications. This may include using existing panels, and if required, fabricating customised panels. The panels are then shipped and erected onsite, with the panels secured to one another as described above. Securing the panels 3, 85 to one another may allow quick mechanical/structural interconnection, power,

communications and HVAC. This may be in contrast to other systems that may require technicians to separately wire power, lighting, communications and to install ventilation to the office.

[0110] In some examples, the office pod 93 may also include one or more modular floor panels 95 with features similar to those of the modular wall panels 3 and ceiling panels 85 described above.

Power line communications

[0111] In some examples, the electrical circuit 13 may be used for power line communications. That is, using electrical wiring that carries both power and data. Examples of power line communications include those specified by following standards: IEEE 1901 (HomePlug AV), ITU-T G.9960/1 (G.hn), ITU-T G.9903 (G3- PLC), ITU-T G.9904 (PRIME), IEC 61334-5-1, where the names in the parentheses indicate common names given to these standards, or examples of these standards. [0112] Thus in some examples, the first and second electrical connector 11, 19 are electrical interfaces for a common data and power line. In some examples, the panels, 3, 85, 95 may further include a power line modem to modulate and demodulate signals on the power line.

[0113] Power line communications may be used for communications and automation of one or more devices or components of the system 1. For example, the light fittings 87 and HVAC may be selectively controlled through signals on the power line communication. Therefore in some examples, the modular wall panels 3 may also include electronic controllers in communication with the electrical circuit 13 for controlling these devices.

Variation

Variation with first and second interface regions on opposite sides

[0114] A variation of the modular wall system is illustrated in Fig. 18. In this alternative, the modular wall panel 3' includes a panel body 5' that has a first interface region 7' on one side and a second interface region 15' on an opposite side. Thus in this variation, not all sides of the modular wall panel 3' may be secured to any side of the adjacent modular wall panel 103', 203'.

[0115] For example, the side with the first interface region 7' may be the "male side" having the interlock protrusion 9. The side with the second interface region 15' may be the "female side" having the interlock recess 17' . In this variation, only the male side can be secured with the female side of an adjacent modular wall panel. This variation may be useful in circumstances where modular wall panels 3', 103', 203' should be configured in certain orientations and it is desirable to prevent, or reduce the likelihood, assembly of the panels in an incorrect configuration. Variation with combination of different interface types

[0116] Another variation will now be discussed with reference to Figs. 19(a) to 28(c).

[0117] In this variation, the modular wall panel 303 comprises two different interface types. A first type includes first and second interface regions 307a, 315a that include a fixed interlock protrusion 309a and a fixed interlock recess 315a. A second type includes first and second interface regions 307b, 315b that include selectively extendable and retractable interlock protrusions 309b and a corresponding interlock recess 317b.

[0118] Referring to Figs. 19(a) and 19(b), the modular wall panel 303 may include an internal frame 303 formed of tubular members that are provided at the perimeter of the modular wall panel. In some examples, the internal frame 303 may be substantially square or rectangular. The tubular members may be RHS welded (or otherwise joined together) to form a substantially square or rectangular shape.

[0119] The wall panel 303 may also include insulation 31, planar surface boards 33a, 33b and laminates 35a, 35b as described above.

First interface type - Fixed interlock protrusion

[0120] Referring to the example of a wall 400, as shown in Fig. 22, the first interface types are provided at upper and lower sides 325', 325" ' of each wall panel 303 such that the respective first interface types of the wall panels 303 engage with each other to connect the wall panels 303 vertically (i.e. one on top of another such as wall panels 411, 412, 413, 414).

[0121] Referring to Fig. 20(a), a top side 325' of the wall panel 303 includes a first surface portion 361 that has a first interface region 307a and the fixed interlock protrusion 309a. The upper side 325' also includes a second surface portion 363 having a second interface region 315a and the fixed interlock recess 317a. The lower side 325" ' similarly has an arrangement of both a first surface portion 361 and a second surface portion 363 (and corresponding first and second interface regions 307a, 315a. The arrangement of having both a first interface region 307a and a second interface region 315a on a side 325 may assist connecting with other modular wall panels in the system. In some examples, having an asymmetric arrangement of the first and second interface regions 307a, 315a may assist orientation of wall panels 303. For example, if one surface of a wall panel should be an interior surface and the opposite surface should be an exterior surface. The asymmetric arrangement may prevent inadvertent mounting in the wrong configuration.

[0122] In this example, the fixed interlock protrusion 309a may include RHS that extend from corresponding hollows of an internal frame 321. In some examples, the fixed interlock protrusion 390a may be fabricated by inserting an RHS into the internal frame 321 and welding the RHS in place. In other examples, other methods may be used such as using fasteners to fix the fixed interlock protrusion relative to the internal frame 321. It is to be appreciated that the fixed interlock protrusion 309a may have some of the advantages of the extendible protrusion 9 discussed above.

[0123] The first interface region 307a of the first interface type also has a first electrical connector 11 (similar to the examples discussed above). In some examples, this may include providing the interlock protrusion 309a with electrical connectors 11 at a distal end and/or within a hollow of the protrusion.

[0124] The fixed interlock recess 317a may be formed from a hollow of the internal frame 321. In some examples the fixed interlock recess 317a may including a lining or coating to assist in insertion of the fixed interlock protrusion 309a. Such a lining or coating may include a polytetrafluoroethylene based material. The lining or coating may also assist in corrosion resistance of either or both the material of the fixed interlock recess 317a or fixed interlock protrusion 309a. [0125] The second interface region 315a of the first interface type also has a second electrical connector 19 to form electrical connections with a respective electrical connector 11 (similar to the examples discussed above).

Second interface type - retractable interlock protrusions

[0126] The second interface types are provided at lateral sides 325", 325" " of each wall panel 303 such that the second interface types of wall panels 303 engage with each other to connect the wall panels 303 horizontally (i.e. side-by-side such as wall panels 403, 413, 423, 433, 443).

[0127] In this example, the second interface type includes a first interface region 307b that includes interlock protrusions 309b that are selectively extendable and retractable. When extended, the interlock protrusions 309b may be configured to engage with a corresponding interlock recess 317b of a second interface region 315b. When retracted, the interlock protrusions 309b may be configured to disengage from the corresponding interlock recess 317b.

[0128] In the illustrated example in Fig. 20(b), the second interface type may have a first interface region 307b provided at one side 325" " and a second interface region 315b provided at another side 325 " . This may reduce the chance of inadvertently positioning the wall panels in the incorrect configuration (e.g. inside and outside facing surfaces). However it is to be appreciated that in some other examples, a particular side 325 may have the second interface type including a mixture of first and second interface regions 307b, 315b.

[0129] An example of a mechanism of the second interface type will now be described with reference to Figs. 21(a) to 21(c). This example includes an interlock protrusion 309b that includes a rotatable latch 310. In Fig. 21(a), the rotatable latch 310 is in a retracted configuration. The rotatable latch 310 is connected by linkage arm 355 to a spindle 53. Rotation of the spindle 53 allows selective configuration of the rotatable latch 310 and, in this example, rotation of the spindle 53 in an anti-clockwise direction will configure the rotatable latch 310 towards the extended configuration as shown in Fig. 21(b).

[0130] When the rotatable latch is in the retracted configuration, the interlock protrusions 309b do not extend past the outer perimeter of the side 325" " . This may be advantageous during installation of the wall panels 303 as the protrusions 309b will not interfere with moving and positioning of the wall panels 303. Once the wall panel 303 is positioned in place relative to one or more adjacent wall panels 303', the spindle may be rotated to extend the rotatable latch 310.

[0131] As illustrated in Fig. 21(c), in the extended configuration the rotatable latch 310 extends into, and engages with, the second interface region 315b. In this examples, this includes the rotatable latch 310 extending into the interlock recess 317b. The rotatable latch 310 is in the form of a hook that engages with a corresponding strike 312 of the second interface region 315b. The engagement of the hook and strike 312 secures the adjacent panels 303, 303' to one another.

[0132] In some examples, the interlock protrusions include a first rotatable latch 310' and a second rotatable latch 310" (as shown in Fig. 20(b)). The first rotatable latch 310' is rotatable in a clockwise direction from the extended configuration to the retracted configuration. The second rotatable latch 310" is rotatable in an anticlockwise direction from the extended configuration to the retracted configuration. That is, the first and second rotatable latch rotate in opposite direction towards respective extended and retracted states. In some examples, both the first and second rotatable latch 310', 310" are manipulated by the same spindle 53.

[0133] One advantage of having the first and second rotatable latch 310', 310" rotating in opposite directions is that it may assist in centring and alignment when connecting with adjacent wall modules 303. Referring to Fig. 21(c), when the rotatable latch 310 is rotated anti-clockwise, over travel of the rotatable latch 310 may result in force against the strike 315b such that the panel 303 is biased upwards. However if a second rotatable latch (such as latch 310" in Fig. 20(b)) is provided, then the second rotatable latch would provide force in an opposite direction which will help relieve imbalance and assist centring and alignment.

[0134] Figs. 21(a) to 21(c) also illustrates first and second electrical connectors 11, 19 that may be provided at the first and second interface regions 307b, 315b. In some examples, these may include contact connectors. In other examples, the first and/or second connectors may be retractable and extendable to provide the electrical connection between the wall panels 303, 303' . In some examples, retracting and extending the electrical connectors may be affected by operation of the spindle 53 so that rotating the spindle 53 can simultaneously engage adjacent wall panels 303 and provide the electrical connection (and conversely disengage wall panels 303 and disconnect the electrical connectors).

[0135] Although the above example of the second interface type is for a rotatable latch, it is to be appreciated that other types of extendable and retractable interlock protrusions may be used as the second type, including those that are linearly extendable and retractable as described in Figs. 2(a) to 2(c).

Types of panels

[0136] The system 1 may include a variety of different wall panels 303. This may include wall panels that are substantially square such as panel 413 illustrated in Fig. 22. For tailoring to different desired room and wall dimensions, smaller panels may be provided, including rectangular shaped panels. For example, panels 401, 402, 403, 404 have a relatively narrower width than other panels 413, 423 in the wall 400. This allows adjusting to the desired length and/or width of the walls of a room. Similarly, the panels may have various heights to adjust to a desired height of a wall or room and panels 411, 421 have less height compared to other panels such as panels 413,423. Wall panels 303 of different sizes may also be used to adjust to different requirements or designs for example, panels 414, 424 may be panels more suited for lower portions of the wall and may have features suitable for such use, such as additional electrical and/or communications sockets 71. [0137] The wall panels may also include wall panels that include windows 336 such as panels 421, 423, 432, 433. A detailed example of a window panel 432 is illustrated in Figs. 23(a) to 23(c) that shows a square window 336 surrounded by the internal frame 321.

[0138] The system 1 may also include edge panels 503 that are located at or near where traditional skirting boards and cornices are located in a room. The edge panels 503 may have similar features to the wall panels 303 (and in some cases are modular wall panels 303) so that the edge panels 503 can engage with other edge panels 503 and wall panels 303. This may include having first and/or second interface regions. In some further examples, the edge panels 503 may also have electrical connectors to connect with the wall panels 303 and other edge panels 503. In some examples, the edge panels 503 may be corner edge panels that connect wall panels 303 that extend in different planes as shown in Figs.24(a) to 27(c).

[0139] Figs. 24(a) to 24(c) illustrate an example of a corner edge panel 506 to connect a wall 400 to a ceiling. The corner edge panel 506 has a first internal frame portion 321 ' that is connected to adjacent wall panels 303 and a second internal frame portion 321 " to connect with ceiling panels (not shown). The second internal frame portion 321 " includes fixed interlock protrusions 509a to engage with respective interlock recesses of ceiling panels. The second internal frame portion 321 " may also include retractable interlock protrusions 509b and corresponding interlock recesses 517b. The corner edge panel 506 may also include a board 508 parallel to the ceiling. The corner edge panel 506 may also have one or more HVAC system components. For example, a HVAC ventilation duct 510, and HVAC inlet/outlet 514 that leads into the duct 510, and a ventilation grill 512 to provide a fluid passage between the room and the duct 510.

[0140] Figs. 25(a) to 25(d) illustrate another example of a corner edge panel 516 that connects a wall 400 to a ceiling (not shown) and also supports glazing 536. [0141] Figs. 26(a) to 26(c) illustrate yet another example of a corner edge panel 516 for connecting two adjacent perpendicular walls and a ceiling. In this example the corner edge panel 516 has retractable interlock protrusions 509b and respective interlock recesses 517b to engage with corresponding components of adjacent corner edge panels or ceiling panels.

[0142] Figs. 27 (a) to 27(c) illustrate a corner wall panel 520. In this examples, the corner wall panel 520 connects two adjacent and perpendicular walls.

[0143] Figs. 28(a) to 28(c) illustrate another edge panel 522 to connect to a wall 400 and to support glazing 536.

[0144] It is to be appreciated that other types of wall panels may be used, including those with combinations of the various features in the above described examples.

[0145] It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
