Description

DISPLAY ASSEMBLY BACKGROUND OF THE INVENTION

[0001] This invention relates to a display assembly i.e. to a structure which may be illuminated or carry an aesthetic, ornamental or utilitarian device, which may function as a screen for visual display purposes, form a component of an audio system, be used as a module in a communication network or provide support to, otherwise interact with, diverse mechanisms and components such as tools, phones, computers, toothbrushes, cups, pictures and the like. These are exemplary, non-limiting applications.

[0002] The prior art discloses various display constructions which are based on the use of modular principles, often on the use of pre-constructed elements which can be interconnected or used in a variety of ways.

US6167664 describes a framework used to support removable facing panels and modular office components. US5694727 describes a wall system which is formed from an array of individual panels which extend in rows and courses. US5400560 describes a system which is suited for use in an office or similar institution. US5321579 relates to a panelling system wherein a screen is mounted to a cantilevered arm.

[0004] US20030154673 discloses partition panels which are sectionable into elements. Each element may be used in a particular way. or serve a particular function. A partitioned panel is internally wired to provide power and data connections. [0005] A wall mountabte frame structure for mounting equipment at various chosen locations is disclosed in WO2007/1 3510. Panels are attached to a frame which supports electrical equipment and shelves. Cables, concealed behind the panels, are connected to electrical devices, which are positioned between adjacent panels, aligned with frame elements.

[0006] The various prior art arrangements are. in the applicant^'s view, not always sufficiently adaptable to be used effectively in diverse ways. The making of connections (electrical, audio, video and data) can be problematic and can negatively impact on flexibility of use, and on the provision of an attractive end product (as installed). [0007] An object of the present invention is to provide a display assembly which lends itself for use in a wide range of applications, which is aesthetically pleasing, and which can be varied in size, and wherein the transfer of electrical energy, and the making of connections, for electrical, audio, visual, data and other purposes, in respect of devices incorporated in, or used with, the display assembly, is facilitated. SUMMARY OF THE INVENTION

[0008] The invention provides a display assembly which includes a backing section and a panel section, wherein the backing section has a first side, an opposed second side, formations for engagement with an external support with the second side facing the external support, a first locating arrangement on the first side and a first component of an electrical energy transfer mechanism, and wherein the panel section has an inner side, an outer side, a second component of the electrical energy transfer mechanism and a second locating arrangement, on the inner side, which is interactive with the first locating arrangement thereby to cause the inner side to be positioned correctly relative to the first side, whereupon electrical energy is transferable from the first component to the second component.

[0009] The electrical energy transfer mechanism may indude at least one of the following: a mechanism which transfers electrical energy using inductive coupling processes; a mechanism which is based on the use of interengageable electrical supply and receiving contacts.

[0010] To effect inductive coupling the electrical energy transfer mechanism may include a circuit which in use is connected to a source of electrical energy and which produces an inductive electromagnetic field via at least one transmitting antenna or winding. This is in the backing section. The panel section may then include a receiving antenna or winding which is positioned so that it is etectromagneticaliy coupled to the transmitting antenna when the panel section is correctly engaged with the backing section. Additional circuitry provided in the panel section is then used to process and condition the electrical energy which is received via the receiving antenna. [0011] Electrical energy may be transferred at any appropriate voltage e.g. at a mains voltage (220 volts AC, 110 volts AC or any other suitable voltage which accords with a chosen standard) or at a direct current (DC) operating voltage at a suitable level. The invention is not limited in this respect.

[0012] The panel section may include at least one energy storage device, such as a battery, connected to the second component.

[0013] The panel section may be adapted to provide electrical energy to one or more devices which may be permanently connected to the panel section or which may be connected to the panel section when and as required. This energy may be provided via at least one inductive coupling arrangement or by direct electrical contact e.g. using sockets, pins, plugs or the like.

[0014] The electrical energy transfer mechanism may additionally or alternatively be based on the use of interengageable terminals e.g. sockets and pins or plugs. For example, a first set of electrical terminals may be on the backing section and a second set of electrical terminals may be provided on the panel section. The second set of terminals may be complementary to, and electrically engageable with, the first set of terminals, when the panel section is correctly positioned relative to the backing section and is engaged therewith.

[00 5] The first set of electrical terminals may include an electrical socket and the second set of electrical terminals may include an electrical plug which is of complementary shape to and which is engageable with the socket. The socket may be provided on the backing section and the plug on the panel section, or vice versa. [0016] The backing section may be secured directly to a support surface provided by a fixed or permanent external structure. However, it is preferred to make use of an intermediate device, which provides said support surface and which is attached to a fixed or permanent external support structure. One benefit in this respect is that it is possible to engage the backing section correctly orientated and positioned relative to the intermediate device with ease. Another benefit lies in the fact that the backing section could be engaged with a hook action with the intermediate device and could be disengaged therefrom with similar ease. [0017] in one form of the invention the backing section includes first and second members. The first member may have a front side, and a rear side which constitutes said second side of the backing section. The second member may have an outer side which constitutes said first side of the backing section and an inner side which opposes the front side of the first member.

[0018] The front side of the first member may be formed with at least one formation, and preferably with a plurality of formations, each of which is adapted to be engaged with a respective first set of electrical terminals.

[00191] The second member may be of complementary shape to the first member so that it can be superimposed on and can be engaged with the first member. The second member may include a plurality of openings and a respective first set of electrical terminals may pass at least partly through each respective opening, or be accessible through each opening.

[0020] The first component of the electrical energy transfer mechanism may be positioned at least partly in a space formed between opposing sides of the first member and of the second member. An electrical circuit may be positioned inside the space and may be connected to an electrical supply source (mains or otherwise), and to transmitting or inductive windings or to electrical contacts or terminate or to both.

[0021] The first locating arrangement on the first side of the backing section may comprise one or more formations which are engageable with complementary formations included in the second locating arrangement on the inner side of the panel section. If electrical terminals are used in the electrical energy transfer mechanism then each set of terminals may be provided in or incorporate structure which is included in the first locating arrangement and which assists in correctly positioning the panel section on the backing section.

[0022] The backing section may include fixing components which secure the second member of the backing section to the first member of the backing section. Any appropriate technique may be used in this respect. In one example of the invention each fixing component comprises a short stud, on the front side of the first member which is engageable with a socket, of complementary shape to the stud, on the inner side of the second member.

[0023] The second member may include a plurality of apertures and a respective first set of electrical terminals may extend, at least partly, through a respective aperture so as to be accessible on the outer side of the second member.

[0024] The panel section may be one of plurality of panel sections, which may be similar or different. Each panel section may be separately engageable with a separate backing section. Alternatively, a relatively large backing section may be provided and a plurality of panel sections may be engageable therewith.

[0025] The panel sections may be identical to one another, or vary in shape, size and formation.

[0026] The panel section may be made in any appropriate manner. In one form of the invention the panel section includes a first component which is engageable with a second component which is in the nature of a cover. The cover (second component) may have an outer side and an inner side. The first component may have an inner side which faces the inner side of the cover and an outer side which, in use, faces the backing section.

[0027] The cover and the first component may be interengageable through the use of a plurality of clip formations. [0028] Electrical circuitry, including the aforementioned second component of the electrical energy transfer mechanism, may be positioned at least partly inside a space formed between opposing surfaces of the cover and of the first component.

[0029] The second locating arrangement on the panel section may be formed, at least, by one or more formations which are engageable with complementary formations in or on the backing section.

[0030] The first component of the panel section may include a plurality of formations whereby the panel section can be fixed to a backing section. Appropriate fasteners can be used for this purpose. These formations may include or contain elements which are magnetically engageable with other elements which are correctly positioned and which are on the first side of the backing section. For example, the elements on the first component may comprise high strength magnets e.g. rare earth magnets, and elements of a magnetic material e.g. steel, or oppositely polarized magnets, may be positioned on the outer side of the backing section.

[0031] Preferably the elements on the outer side of the backing section are located in respective small recesses, and corresponding magnetic elements on the outer side of the panel section are positioned in respective protrusions to facilitate correct positioning of the panel section relative to the backing section. [0032] Depending on the mass of the pane) section use of a magnetic interengagement between the panel section and the backing section may be adequate to support the panei section in the backing section. However, if the panel section is heavy then, in place of or in addition to the magnets, one or more fasteners may be used to fix the first component to the backing section and, subsequently, the cover may be engaged with the first component.

[0033] The nature and construction of the cover are determined primarily by aspects of use and appearance of the panel section in question. For example, one or more light sources may be provided in a space between the cover and the first component. In this event the cover may be made from a light diffusive material. The light sources may be uniformly coloured, varied or, in use, the colour of tight from the light sources can be changed on a continuous basts, on a mood basis or for different purposes.

[0034] The cover may form part of a display screen e.g. a video or television screen or. depending on the size of the cover, constitute the entire screen. [0035] The cover may include or overlie an audio outlet e.g. a loudspeaker. The cover may include terminals or connections to one or more electrical appliances, a cellular telephone, a computer or the like. The invention is not restricted in this regard. For example, provision may be made on the cover for a cellular telephone, correctly positioned on the cover, to be charged automatically, preferably by means of inductive coupling techniques. Another possibility is to include a terminal on the cover to which a cellular telephone or other device can be connected for charging purposes.

[0036] It is recognised that, increasingly, various appliances are powered by chargeable batteries as opposed to a mains supply. For example, battery powered electrical drills, screwdrivers and the like are being used to an increasing extent. It falls within the scope of the invention for the pane) section to include a mechanism for recharging these types of appliances. This may be via an inductive coupling process, by direct electrical contact, or a combination of these techniques may be employed. The invention is not limited in this respect.

[0037] The cover may include at least one shelf, a holder for a glass or a cup, or one or more hooks for use with a movable appliance or device. It falls inside the scope of the invention for the cover to be internally illuminated according to requirement.

[0038] If the cover forms part of, or an entire, display screen then suitable connections can be used to transfer audio or visual signals to the screen and to power the screen. Similarly, data can be transferred to or from the screen.

[0039] The screen may comprise part of an interactive computer network.

[0040] A plurality of the panel sections may be connected to at least one backing section with the panel sections arranged in an array of abutting rows, or abutting columns, or hi rows and columns.

[0041] The panel section may include at least one energy storage device e.g. a battery which is charged by the transfer of electrical energy from the first component to the second component. One or more power outlets on the panel section e.g. engageable with a plug or socket, according to design, may be provided on the panel section and may be powered, at least partly, by the energy storage device. [0042] The backing section and the panel section may be made from any suitable materials depending, at least, on the intended application. The invention is therefore not limited in this respect.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0044] One objective of the invention is to provide a display assembly wherein at least one panel section, which can be configured in a variety of forms or shapes, can be engaged with ease to at least one backing section. The panel section may be one of a plurality of similar or different panel sections which are attached to a single backing section or to more than one backing section. A further objective is to facilitate the making of electrical connections between the backing section and each panel section, for electrical energy transfer purposes, or for establishing video, audio or data links, or the like.

[0045] As used herein the phrase "electrical connections^* refers to electrical power connections, whether AC or DC, or at a high or low voltage, data connections, connections for signal, communication and data transfer purposes, connections for audio or visual purposes and the like. The invention is not restricted in this respect.

[0046] Preferably the display assembly of the invention is based on sizes which conform to international paper sizes IS0216. Although this is desirable ft is not limiting. There are however benefits associated with this size standard. Each size in the series is defined by halving a preceding size along a larger dimension. Typically, therefore, each panel section (referred to hereinafter) preferably has an outline conforming to one of the sizes A1, A2, A3 etc. Conveniently, for many applications, each panel section has an A4 dimension. If large panels are required, for example for a visual display, then a panel could have an appropriate dimension. To the extent that the outline does not conform to the outline of a standard television display (for example) then, a perimeter portion of the display, not occupied by the visual image, could be blacked out

[0047] If a panel section is to be used for audio purposes, either to pick up sound or to distribute sound, then the material from which the panel section is made should have suitable acoustic properties.

[0049] If a panel section is to be used for power delivery purposes, for example to host an electrical kettle or the like, then electrical connections which are made to the panel section are correspondingly rated and insulated. [0049] Considerations of the aforementioned type are not described in detail hereinafter.

[0050] The following description is thus made herein primarily with reference to conceptual and innovative details although, merely by way of non-limiting examples. various practical embodiments of different panel sections are illustrated.

[0051] Figure 1 of the accompanying drawings illustrates an electrical socket 10 which is used for the making of electrical connections to corresponding plugs 12 (see Figure 2) in implementing a display assembly according to one form of the invention. The electrical socket includes a pedestal 14 and a centrally located projection 16. of circular cross-section. An annular passage 18 extends into the projection from an outer face 20. The annular passage contains a tubular electrical contact 22. A central spigot 24 contains a concentrically positioned slender tubular electrical contact 26.

[0052] The contacts 22 and 26 are respectively connected to isolated terminals 22A and 26A on an underside of the pedestal. The terminals can be connected to appropriate leads using solder, clips or the like.

[0053] Figure 2 is a side view of the plug 12 for use with the socket of Figure 1 while Figure 3 shows the plug 12 in cross-section. The plug has a cup-shaped housing 30 with a central conductive pin 32 and a surrounding conductive tube 34. The plug can be engaged with the socket and. when this occurs, the pin 32 slides into the contact 26 while the tube 34 engages electrically with the contact 22.

[0054] Figure 4 shows, in perspective, an intermediate support 40 which is made from a suitable material, e.g. aluminium. The support has a number of apertures 42 to reduce its mass and cost. The support is generally rectangular in outline and. at each corner, has a respective rebate 44 which has a fixing hole 46 in a pedestal. Close to each corner is a respective fixing and locating spigot 48.

[0065] Figures 5, 6 and 7 are different views of a first member 50 which forms part of a backing section used in the display assembly. The first member is preferably made from an appropriate plastics material. It is formed with a plurality of regularly spaced upstanding sets of formations 52 on what is referred to herein as a front side 54. Small studs 56 are located at regular spacings on the front side 54. Primary fixing formations 58, in the form of apertures, are centrally positioned and extend through the first member.

[0056] Figure 8 illustrates in perspective the front side 54 of the first member 50. A respective socket 10 is engageable with a twisting action in a secure manner with a respective set of first formations 52.

[0057] Figures 9 and 10 respectively show an outer side 60, and an inner side 62, of a second member 64 included in the backing section. The second member has a plurality of apertures 66 at locations which coincide with the spacings between the formations 52 shown in Figure 5. Each aperture is at a base of a recess which is in the form of a well 68. Four shallow sockets 70 are adjacent each well. Each socket carries a steel element 72 which is firmly embedded in the socket. [0058] The inner side 62 has a number of fixing components 74 (shown on an enlarged scale in Figure 11). Each fixing component is in the nature of a stud with a base 76 which is uttrasonically welded to the inner side 62. and a tubular projection 78. A shallow wall 80 forms a periphery of the second member. [0059] The second member is shaped and sized to be superimposed on the first member. When the second member is correctly positioned relative to the first member and is in contact with the first member, the tubular projections 78, on the inner side 62 are forced into contact with the corresponding studs 56 on the front side 54 of the first member and then uitrasonicaily welded together.

[0060] Depending on requirement, a respective socket 10 then extends through one of the apertures 66 and is visible on the outer side 62. Due to the surrounding weii 68 the socket 10, although visible and accessible, does not protrude beyond a planar surface 82 of the second member. A shallow cavity is formed inside the backing section between the inner side 62 of the second member 64 and the opposing front side 54 of the first member 50. Electrical connections to the various sockets are made, as required, by means of appropriate conductors which are positioned inside the space defined by this cavity.

[0061] The assembly of the backing section is normally done under factory conditions. Wires or conductors to the various sockets are passed through one or more apertures, not shown, provided for this purpose.

[0062] Figures 12 and 13 respectively illustrate in perspective an outer side 86 of a first panel component 88. and an inner side 90 of the first panel component 88. The panel component is rectangular in outline, preferably complying, as has been stated, with a standard size in the international size standard IS0216. The outer side 86 has an upstanding conical formation 92 with a central aperture 94. Surrounding the conical formation 92 are four small tubular formations 100 and, positioned inside each tubular formation, is a respective strong magnet 102 comprising, for example, a strong rare earth magnet. On opposed shorter edges the first component has resilient clips 104.

[0083] On the inner side 90 each conical formation 92 defines a recessed well formation 110. [0064] Figure 14 illustrates, in perspective, the inner side 90 of the first panel component 88. A plug 12 of the kind shown in Figures 2 and 3 is engaged, with a twisting action, with a selected aperture 94 in a conical formation 92. Terminals 114 to the pin 32 and conductive tube 34 are accessible on the inner side 90. These terminals are connected, as appropriate, to various electrical members, elements or devices, not shown. For example, the terminals may be connected to a plurality of Ught sources, to a loud speaker system, to a microphone system, to a custom-designed electrical circuit or the like.

[0065] The construction and nature of the socket in Figure , the plug in Figures 2 and 3, and, in general, of the electrical terminals, may be varied, as required. The illustrated constructions are exemplary only and are non-limiting. For example, to make data connections compact plug and socket structures may be provided. Additionally, a plurality of plug and socket formations may be provided so that these are engageabte with one another simultaneously. For video and communication purposes use may be made of shrouded cables as is known in the art and the socket and plug structures may be varied accordingly.

[0066] Figure 15 shows in perspective the outer side 86 of the first panel component 88. The pin 32 and the surrounding tubular contact 34 of the plug 12 are surrounded by the conical formation 92 which thus is protective but also supportive. [0067] Figure 16 and Figure 17 respectively show an outer side 120, and an inner side 122, of a cover 124 which is used in a panel section. The cover is made from any appropriate material and, merely by way of example, for lighting purposes the cover is made from a wholly or partly diffusive or translucent plastic material.

[0068] The outer side 120 is planar and is surrounded by a wall 126 which has clip formations 128 along each of its opposed shorter edges. The cover is engageabie with the first component 88, shown in Figures 12 and 13, by coupling the clips 104 to the formations 128. A cavity 130 between the side 122 and the opposing side 90 of the first component provides a space which can, by way of example, accommodate one or more light sources, a loudspeaker, a microphone or the like. The outer side 120 and the inner side 122 may be formed by a video display surface, a touch screen or the like.

[0069] Figure 18 shows, in perspective and in partial cross-section, the cover 124 coupled to the first component 88. The plug 12 is exposed and accessible on the outer side 86 and is surrounded and protected by the conical formation 92. The cavity 130, between the sides 122 and 90, accommodates wiring, electrical components or the like.

[0070] In use of the display assembly an intermediate support device 40 of the kind shown in Figure 4 is attached to a surface of a suitable fixed or "permanent" supporting structure at an appropriate position. Normally the supporting surface is vertical e.g. a side of a wall, but this is not necessarily the case. It is possible to use the display assembly in a horizontal orientation, for example with the intermediate support device fixed to a roof structure.

[0071] Electrical leads which extend to the backing section are passed through one or more of the apertures 42 and are connected, preferably in a concealed manner, to incoming, and outgoing, conductors, as appropriate. Suitable switches are provided, as appropriate, in the leads.

(00723 The backing section, comprising a first member 50 connected to a second member 64 in the manner which has been described, is then attached to the intermediate support 40. This is easily done in that the four primary fixing apertures or formations 58 of the first member 50 are engaged with a direct insertion action, followed by a sliding action, with the studs 48 of the intermediate support 40.

[0073] The formations 58 are cross shaped - a feature which allows the backing section to be moved to a limited extent to the left or to the right, or up or down, relative to the intermediate support, in order to couple these components together. Thereafter, according to requirement, a panel section is attached to the backing section at a desired location. The magnets 102 on the first panel component 88 are, effectively, automatically aligned with the respective steel elements 72 (or oppositely polarized magnets) in the second member 64. The magnets are strong and. as a consequence, the panel section is firmly attached to the backing section. The steel elements are held in formations which are slightly recessed and. conversely, the magnets are in formations which protrude slightly from the outer side 86. These features allow for a physical engagement of the panel section with the backing section, with the magnetic forces keeping the protrusions located within the respective recesses. [0074] Figure 15 shows a panel section with a single connecting plug. Figure 9 (by way of example only) shows a second member 64 of the backing section wherein provision has been made for sixteen sockets. It is of course not essential that each aperture 66 should be occupied by a corresponding socket. However, the arrangement is one in which the position of a socket can be varied as required to any one of the apertures. Different factors play a role here including the nature of the connections to be made and the size of each panel section.

[0075] Figure 19 illustrates an arrangement wherein four panel sections 128. each of A4 size, are positioned on, and are engaged with, a single backing section. Figure 20 shows an arrangement wherein each panel section 128A is of A5 size. Consequently four panel sections 128A make up an A4 outline and, effectively, replace a panel section 128. This type of variation can be continued, within reason, by using appropriate sizes of panel sections. [0076] Figures 19 and 20 show panel sections with planar outer faces. By way of example reference is made to Figures 21 to 23 to obtain further insight into possible variations.

[0077] Figure 21 shows a panel section 142 which is orientated with a longer dimension vertical. The panel section carries a soap tray 144 and a holder 146 for a drinking glass.

[0078] Figure 22 shows a panel section 150 which on an outer side 120 has a plurality of hook formations 152. This type of structure is usable in a workshop, in a kitchen, in a retail outlet or the like.

[0079] Figure 23 shows, from one side, a panel section 160. In this instance the conical formation 92, although present, does not house a corresponding plug. An outer side 120 of the cover 124 is formed with relatively large hooks 164 which for example can be used as coat or hat hooks. [0080] In many applications the magnetic interengagement of a panel sections with a backing section provides more than adequate security of attachment. However, if a panel section is particularly heavy then it is not prudent to rely solely on magnetic forces to keep the panel section in position. Figure 24 shows in perspective and cross-section an outer side 86A of a first panel component 88A which has been modified to include a number of deep tubular sockets 168 dose to respective corners of the panel component.

[0081] A corresponding backing section 170 has a modified first member 172 which includes sockets 174 to which are bonded internally threaded steel tubes 176. [0082] The backing section is attached to a wall using an intermediate support device in the manner which has been described. Thereafter the assembled panel section is located on the backing section and fasteners 180 are inserted into the sockets, passing through registering holes 182 in the associated modified first panel component 184 and are threadedly engaged, using a suitable tool with the respective steel tubes 176. The heads of the fasteners 180 are recessed and are not normally visible. If required plugs, not shown, could be frictionally engaged with the sockets 168 to provide a smooth and flush external finish to the outer face of the panel section.

[0083] In one convenient form of the invention (not shown) an upwardly facing surface of a shelf of a panel section has a socket outlet with which a plug on an appliance e.g. a kettle is engageabie when the kettle is placed on the shelf.

[0084] The description relating to the preceding examples of the invention deals primarily with an electrical energy transfer mechanism based cm the use of interengageable electrical terminals e.g. plugs and sockets. In the illustrated embodiments the plugs and sockets are generally of circular outline This is exemplary only. It is preferred however that the plugs and sockets are mounted in formations, in which, in themselves are of complementary form so mat. when a panel section is to be connected to a backing section, physical alignment of the two sections is facilitated in such a way that a plug is effectively automatically connected to a socket when the panel section is correctly oriented.

[0085] Reference has also been made to the use of magnets which provide a convenient means of coupling a panel section to a backing section. If the magnets are of a suitable composition then they can be used for conducting electrical current provided that the passage of the current does not, in itself, interfere adversely with the magnetic properties of the magnet. Thus, a magnet which is magnetically attached to, say. a steel component can be used to establish an electrical path through the component and the magnet and, in this way, an electrical current can be passed between the panel section and the backing section. This electrical current can be used for power transfer purposes or to convey electrical signals of any appropriate form e.g. for data, communication, audio or video purposes.

[0086] The use of the magnets in this way can be as an alternative to the plug and socket type arrangement or to an inductive arrangement or in addition thereto.

[0087] An effective form of energy transfer, which lends itself to aesthetically pleasing structures or which is of a sealed or closed form and therefore not liable to damage etc, is provided through the use of inductive coupling.

[0068] Figure 35 shows, in block diagram form, an energy transfer arrangement 198 based on the use of inductive coupling. A backing section (generally of the aforementioned kind but excluding electrical terminals of the type referred to) carries a circuit 200 while a panel section (also of modified form in that it does not include electrical terminals of the kind referred to) includes a circuit 202.

[0089] The circuit 200 includes a connection 204 on a rear side of the backing section which is engageabte with a mains supply e.g. 220 volts AC. 110 volts AC or the like. The mains supply connection is connected to a switch mode power supply 206 which produces a usable low level DC output voltage, e.g. of the order of 19 volts, at output terminals 208. The output voltage is passed through a fitter 210 which fitters noise from the DC supply and improves system stability. A DC output 212 from the filter is fed to a controller/driver 214 which, for example, operates at an interface standard developed by the Wireless Power Consortium for inductive electrical power transfer, over a limited distance. The controller 214 produces an alternating electrical output 216 which is supplied to an inductive transmitter 218 which includes a plurality of windings 218A. [0090] On the receiving side i.e. on the panel section, the circuit 202 is adapted to make use of the power radiated from the transmitter 218.

[0091] The circuit 202 includes a receiver 220 which has a plurality of coils or windings 220A into which electrical power is induced when exposed to an electromagnetic field. The receiver produces an alternating output 222 which is applied to a receiver/rectifier unit 224. This produces a stable DC output 226, at a desired voltage, typically of the order of 5 volts which is passed through a filter 228 to remove noise. An output 230 from the filter is applied to a DC converter 232 which produces an output signal 234 with a voltage which, typically, is of the order of 10 volts and which is applied to a charger 236 which in turn is used to control the charging of a battery 238. Any appropriate battery may be used but a lithium ion battery is preferred in that it has a long life over which it can emit a stable output voltage. Additionally, the battery is rechargeable effectively and repeatedly under the control of the battery charger 236. [0092] When the circuit 200 is energised by means of a mains supply connected to the connector 204, an electromagnetic field 240 is established by the transmitter 218 and, if the receiver 220 is close to the electromagnetic field, typically within 4 cm of the transmitter, electrical energy is effectively coupled into the receiver and, as indicated in the preceding description, the battery 238 is charged continuously and automatically. [0093] A benefit of the inductive coupling arrangement which is possible through the use of circuits of the kind shown in Figure 35, is that contactless energy transfer is achieved between the backing section and the panel section. In this respect, referring for example to Figure 32 which shows a first side 250 of a different type of backing section 252, it is preferred to position the transmitting windings 218A, shown in dotted outline, in a recessed formation 254 of square or rectangular outline and to position the remaining components of the circuit 200 inside a space or cavity between the first side 250 and a second side 256 of the backing section. Similarly, referring for example to Figure 31 which shows an inner side 260 of a modified panel section 262, the windings 220A (shown in dotted outline) are positioned in a projecting formation 264 which is square or rectangular outline and which is of complementary shape to the recessed formation 254. Thus, the formation 264 is engageable with a nesting and close-fitting action with the formation 254, and the windings 220A and 218A are thereby automatically positioned physically close to each other. This is Important to ensure effective and efficient inductive energy transfer from the backing section to the panel section.

[0094] Figure 25 illustrates from a front side and in perspective a configuration 300 of a display assembly according to the invention which can be implemented using the plug and socket approach referred to hereinbefore but which preferably makes use of an arrangement of the kind shown in Figure 35. The display assembly includes a backing section 302, an upper panel section 304 and a lower panel section 306. The upper panel section 304 is shown in Figure 26. It includes a cover 308 and tower and upper shelves 310 and 312 which extend from an outer side 314 of the cover. The upper shelf 312 has three racks 316, 318, 320 which extend upwardly and two spaced bollards 322. The lower shelf 310, which is shown displaced from the main drawing in Figure 26, has a hollow interior 324 within which are two sets of windings 330 and 332, shown in dotted outline. These windings are similar to the windings 218A and each is used, in practice, for transferring electrical energy to a device such as a cellphone, a light or any other device which includes a rechargeable battery, using inductive transfer principles.

[0095] The outer side 314 includes a plurality of spaced apart electrical sockets 336. These accord with standardised sockets and are used with HDMI cables or the like. For example if a tablet (computer) is slotted into the racks then a cord from the tablet can be coupled to one of the sockets, for recharging a battery in the tablet. Excess cord can then conveniently be wrapped around the bollards 322.

[0096] Figure 27 shows a side 360 of the upper panel section 304 which includes a projecting formation 362, substantially the same as what has been described in connection with Figure 31. A space between the side 314 and side 360 accommodates an electrical circuit 202 of the type shown in Figure 35.

[0097] Four strong rare earth magnets 320, is located in respective pillars 324, are positioned around the projection 362. [0098] Figure 28 snows from one side and in cross-section the upper panel section 304. Depending on the weight which is to be carried by the shelves 310 and 312, use is made of mechanical fasteners 370 which extend from the space 362 into appropriate bushes 374 located in projections 376. The projections extend into sockets 378 in the outer side. The fasteners 370 are placed in position before the outer side is fixed to the inner side 360.

[0099] The lower panel section 306. in this example, is a so-called "mood light". Figure 31 shows the inner side 260. of the lower panel section, which is coupled to a cover 380 by means of appropriate clip formations 382.

[00100] Figure 30 shows a board 384 which carries an array of spaced apart light emitting diodes 386 at regular intervals. These diodes may be of any appropriate kind but suitably are tricolour diodes, each of which can be energised using suitable control circuitry which functions under the control of a microprocessor 390 located in a space between the inner side and the outer side (Figure 29). The processor, in turn, can be controlled in any appropriate way, for example, using a touch technique, by means of capatitive coupling, charge transfer principles or the like. Another possibility is to make use of ultrasonic, infrared or radio waves to control the operation of the microprocessor. Techniques which are used for example in remote controls for devices such as television sets or video recorders can be employed for this purpose. [00101] The inner side 260 is clipped to the cover which is translucent and opaque. Thereafter the assembled panel section is fixed to the backing section 252.

[00102] The backing section is shown from a front side in Figure 32 and from a rear side in Figure 33. The first side has recessed formations 254 and holes or passages 380 into which the magnets 326 are positionable. Effective coupling automatically takes place then between the transmitting and receiving antennas in the backing section and the panel section. The panel section is engageable with an intermediate support device 400 which can be fixed to a wail by means of fasteners 402 which, as is known in the art, are placed into holes drilled into the wall and then expanded. This is an initial step. Thereafter, as is shown in Figure 34 and Figure 29, the backing section is clipped into engagement with the support device 400. The support device has shaped securing formations 404 and the second side of the backing section (see Figure 33) has corresponding formations 408 which are engageable with a clip action with the intermediate support device 400. [00103] A benefit of making the recessed formation 254 and the projecting formation 264 of square or rectangular outline is that engagement of a panel section which has a single locating formation with a backing section which also has a single locating formation, is facilitated. This is because such engagement can only be effected if the panel section is correctly oriented relative to the backing section. Such orientation results automatically due to the straight sides of the formations. It is not possible to displace a panel section in an angular sense relative to a backing section as is the case when the locating formations are round e.g. of the kind shown in Figure 9 and Figure 18. The use of multiple locating formations, even if of a round or circular shape, does however eliminate the problem of correctly orientating a panel section relative to a backing section.

[00104] If the locating arrangements do include round or circular formations (projections and recesses) and if an inductive energy transfer mechanism is employed then the transmitting and receiving windings are again, preferably, located in the respective formations to ensure effective energy transfer.

[00105] If the panel sections which are to be coupled to the backing section have significant mass or are expected to carry significant weight in use then, as is shown in Figure 28 fasteners 410 are passed through the panel section into threaded engagement with threaded sockets 412 in the backing section to ensure a sound fitting together of these components.

[00106] The display arrangement shown in Figure 29 relies on the use of a backing section of the kind depicted in Figure 32 which has upper and lower recessed locating formations 254. Although this arrangement is only exemplary it is indicative of the modular-type construction embodied in the principles of the invention in that according to requirement, a single backing section can be configured to be engageable with a plurality of panel sections. Alternatively a number of backing sections could be designed to be engageable with a single or multiple panel sections. Figure 36 for example depicts a backing section 420 which has four recessed formations 254 which are evenly spaced over its operative surface. Each recessed formation is associated with a plurality of electrical windings 218A of the kind described hereinbefore. Other details of the backing section 420 are not described hereinafter. [00107] The backing section 420 can be used in a vertical or horizontal orientation, according to requirement The backing section can accommodate four individual modules or pane) sections, a combination of a double and two single panel sections, a combination of a triple and a single panel section or, if required, a compound panel section which stretches over the length of the backing section.

[00108] Aspects of the embodiments shown in Figure 36 can be extended to make up a backing section (not shown) which is of substantial size and which consists of a plurality of rows and columns of the formations 254 wherein each formation can be associated with a respective complementary formation on a single or a compound panel section.
