DESCRIPTION OF EMBODIMENTS
[0047] In one aspect described herein, there is provided a base unit 100 for mounting to a surface and for electrical connection to a mains or supply power. Figure 1A shows a front perspective view of a general embodiment of base unit 100 and Figure 1B shows a rear perspective view of the base unit 100 of Figure 1A. In one aspect, the base unit 100 comprises a mounting region 110 for mounting the base unit 100 to the surface. In some embodiments, the surface is a wall. In some other embodiments, the surface is a floor. In some other embodiments, the surface is a wall of a box or other enclosure. In other embodiments, the surface is a frame for supporting the base unit.
[0048] In some embodiments, the mounting region 110 is itself a surface which will come into contact with the surface to which the base unit 100 is to be mounted. In other embodiments, the mounting region 110 is a pin, tab or other connector.
[0049] As shown in Figure 1A, base unit 100 also comprises a base connector 120 for connecting the base unit to a cover unit 200 as will be described in more detail below. The base connector 120 is shown generically in Figure 1A but can take on any form that allows connection of the cover unit 200 to the base unit 100. Such forms include a recess for receiving a protrusion from the cover unit, a protrusion for being received in a corresponding recess in the cover unit, a clipping arrangement, or a magnet for attracting and retaining a region of the cover unit. In other embodiments, the base connector is an adhesive, or a loop-hook connector such as a product sold under the trade mark Velcro® by Velcro Industries B.V. In this embodiment, base connector 120 can be either the loop component of the connector or the hook component.
[0050] Base unit 100 also comprises a base supply power input 130 for electrically connecting the base unit 100 to a supply or mains power supply. In some countries, the mains, or supply power is provided as an alternating current (AC) electrical signal of about 240V (for example between about 220V and 260V) and about 50Hz frequency. In other countries, mains or supply power is provided as an AC signal of between about 100V and 130V. Some systems use a frequency of about 50Hz while others use a frequency of about 60Hz. Some supply power systems are single phase and others may be three-phase. It will be understood that any electrical power that would be considered to be supply or mains power can be used.
[0051] In some embodiments, base unit 100 will also comprise a base power output 150 (see Figure 1A) for providing output power to the cover unit 200 when cover unit 200 is connected to base unit 100.
[0052] Base power output 150 can be provided by any suitable means including a direct plug/socket arrangement with a recess provided in base unit 100 leading to conductive elements which make electrical connection with a corresponding electrically conductive element of a cover unit power input 210 (see below), or can be provided by a radiating element that transfers power from base unit 100 to cover unit 200 by induction or other means. An example of this embodiment is described in more detail below. Any other form of power transfer can also be used.
[0053] In some embodiments, base power output 150 and base connector 120 can be provided by the same element. In one such embodiment, the connection of cover power input to the base power output 150 will also provide sufficient support to retain cover unit 200 to base unit 100 without a further additional base connector 120 or other connection arrangement.
[0054] In some embodiments, base unit 100 will also comprise a power converter 140 which converts the supply input power received at the base supply power 130 input to the output power provided by the base power output 150 to provide useable power to the cover unit 200 when in use.
[0055] In some embodiments, the base power output 150 will be shielded or otherwise protected so that no electrically-live element is easily accessible by a user when the base unit 100 is installed. In some embodiments, the default state of the base power output is to an OFF state and is electrically isolated from the mains or supply power, and/or from the output of the power converter 140. In such an embodiment, only when the cover unit 200 is in place will the base power outlet be electrically connected to the mains or supply power and/or the output of the power converter 140.
[0056] Figure 2 shows an embodiment of base unit 300 and cover unit 200 connected together, with base unit 300 mounted to a surface 40 (e.g. a wall), and mains or source power 50 connected to the base supply power 130 input.
[0057] In other embodiments, base unit 100 also comprises a base switch interface 160 for interfacing with a switch element of the cover unit 200, to allow actuation of a switch on the cover unit 200 to be effected on the base unit 100. Figure 3 shows a base unit 100 with base switch interface 160. In some embodiments, base switch interface 160 is an electrical interface such as a radio frequency (RF) receiver for receiving RF signals from a switch on the cover unit 200 when actuated. In some embodiments, base switch interface 160 is an infrared (IR) receiver for receiving IR signals from a switch of cover unit 200. In other embodiments, base switch interface 160 is a component of a touch switch which actuates upon a user touching or near-touching a corresponding switch element on the cover unit 200. An example of such a touch switch arrangement is described in PCT patent application no. PCT/AU12011/001675 (published as WO 12012/083380) entitled “Touch Switch” incorporated by reference in its entirety.
[0058] In other embodiments, base switch interface 160 is a mechanical interface for engaging with a switch element or a cover switch interface of cover unit 200 as is described in more detail in Australian Patent Application No. 2015275225 previously incorporated by reference in its entirety.
[0059] Figure 3 shows a general representation of the components of an embodiment of a switch assembly, connected to base unit 100 according to one aspect. Broadly, in this aspect, switch assembly 500 comprises two sub-assemblies, being base unit switch part 510 and operational part 1200. As shown in Figure 3, base unit switch part 510 comprises a functional part 1000 and a base switch interface 160.Operational part 1200 is for actuation by a user and for controlling the functional part 1000, via the base switch interface 160, for interfacing the functional part 1000 and the operational part 1200.
[0060] It will be noted that the operational part 1200 is not fixed to the base switch interface 160 or the functional part 1000 and is able to move freely with respect thereto as discussed in more detail in Australian Patent Application No. 2015275225 previously referred to, as well as Australian Patent Application No 2015275227 entitled “Switch Assembly, System and Method”, Australian Patent Application No 2015275234 entitled “Push Button Switch Assembly, and Operational Part”; and Australian Patent Application No 2015275233 entitled “Switch Assembly with Rotatable Operational Part”, all previously incorporated by reference in their entirety.
[0061] It will be understood that there can be any combination of different operational parts 1200 and plates or cover units 200. For example, a switch assembly 500 with a small dolly 1201B might be converted to a switch assembly with a big dolly 1201B by replacing the operational part 1200 with a small dolly as described above. In another example, a switch assembly with a round push-button switch might be converted to a switch assembly with a square push-button/rocker switch by changing the operational part and the plate. In another combination, as shown in Figure 4, the appearance of system 300 may be changed completely by changing the existing plate or cover unit 200 with a plate or cover unit 200’ of a different type. In one embodiment, the user interface 1201 can be used, or a different user interface 1201 can be used. In the example of Figure 4, the switch interface 1201 is changed from a round dolly 1201B to a square dolly 1201B’.
[0062] Various aspects are hereby provided to facilitate circuit identification for power outlets and data outlets, of the type described above, as well as for more traditional power and data outlets.
[0063] In one aspect, as shown generally in Figure 5, there is provided an electrical system 300 comprising base unit 100 for connection to a source of mains power 50 (not shown) and for mounting to a surface. Also shown is a cover unit 200 for connection to the base unit 100, wherein, there is provided a circuit identification region 320, for receiving a circuit identification 320’ (not shown in this view), the circuit identification region 320 being recessed.
[0064] The electrical system 300 could be any suitable system including a power outlet, a data outlet and/or a switch or control unit.
[0065] The fact that the circuit identification region 320 is recessed, means that a circuit identification 320’ provided on the circuit identification region 320 is more protected and less likely to be removed or damaged by passing objects that may brush against the surface of the electrical system 300.
[0066] In some embodiments, the cover unit 200 is a functional unit such as described in Australian Patent Application No 2017236025 previously incorporated by reference. In other embodiments, cover unit 200 is simply a face plate for covering a base unit or grid plate. In other embodiments, cover unit 200 is a combination of both face plate and functional unit.
[0067] In some embodiments, the circuit identification region 320 is provided in the cover unit 200.
Figures 6A and 6B show an embodiment of this aspect, in which the cover unit 200 is provided by a face plate, which itself has a circuit identification region 320. Figure 6B shows a side-view cross- section along the line A-A’ of Figure 6A, showing the circuit identification region 320 therein.
[0068] In some embodiments, the circuit identification region 320 is provided on the base unit 100 and is viewable via an aperture 330 provided in the cover unit 200. Figures 7A and 7B show an embodiment of this aspect in which the cover unit (in this case a face plate) 200 is has an aperture 330 therein, as can be seen in Figure 7B by the side-view cross-section along the line B-B’ of Figure 7A.
[0069] In such embodiments, the circuit identification region 320 is able to be provided on a part of the base unit 100, to be viewable via the aperture 330 in the cover unit. Figure 8 shows an embodiment of this aspect, with cover unit 200, in this view, provided by a face plate, having two apertures 330, 330’. As can be seen in this view, a portion of the base unit 100, which in this view is shown as a grid plate 100, can be seen via the apertures 330, 330’. Specifically, this portion is the circuit identification region 320. Circuit identification 320’ can be provided on circuit identification region 320 by any suitable means including direct printing, embossing, provision on a removable tag, and application of an adhesive label, as will be described in more detail below.
[0070] Figure 9 shows another aspect according to some embodiments, in which the circuit identification region 320 or aperture 330 is covered by a window 340, through which the circuit identification region 320 is viewable. In the example shown in Figure 9, face plate 200 has two windows 340, 340’
[0071] Window 340 can be made of any suitable material including plastic, glass or any other transparent or translucent material through which circuit identification region 320 may be seen. In some embodiments still, window 340 could be made of an opaque material and may be removed from aperture 330 or circuit identification region 320 to view the circuit identification therebelow.
[0072] Figure 10 shows base unit or grid plate 100 according to some embodiments, for use in the arrangements shown in Figures 8 and 9. In this view, circuit identification region 320 is shown. Also shown in this view are base switch interfaces 160 as previously described.
[0073] As will be described in more detail below, circuit identification 320’ can be applied to the circuit identification region 320 in any suitable manner.
[0074] Broadly then, there is provided a grid plate for connection to a source of mains power and for mounting to a surface, and for receiving a face plate, the grid plate comprising a circuit identification region for receiving and retaining a circuit identification.
[0075] Figure 11 shows an embodiment of a face plate 200 as shown in Figures 6A and 6B, and in a specific example, a face plate for use with the grid plate 100 of Figure 10. In this embodiment, the circuit identification region 320 is provided on the face plate 200 as a recessed portion. As previously described, the circuit identification 320’ can be applied to this region in many different ways, including in the form of a sticky label, direct printing or inscribing, and via a removable substrate on which the circuit identification is provided.
[0076] Broadly then, there is provided a face plate 200 for connection to a grid plate 100 for connection to a source of mains power and for mounting to a surface, the face plate 200 having a front face 201 and at least one edge 202 angled with respect to the front face 201, wherein there is provided a circuit identification region 320 for receiving a circuit identification 320’, wherein the circuit identification region is recessed.
[0077] Figure 12 shows another embodiment of face plate 200 according to the aspect of Figures 7A and 7B. In this aspect, face plate 200 has an aperture 330 (in the specific embodiment shown in Figure 12, there are two apertures 330). Figure 13 shows a rear view of the face plate 200 of Figure 12, showing the apertures 330. As previously, described, face plate 200 according to these aspects can be placed over a grid plate 200 as shown in Figure 10, to allow viewing of the circuit identification region 320 located on the grid plate 100.
[0078] In some embodiments still, the apertures 330 may have a window 340 inserted therein. An example of such a window 340 is shown in Figures 14A and 14B, with Figure 14A showing a front perspective view and Figure 14B showing a side view.
[0079] Figure 15 shows the face plate 200 rear view of Figure 13, with the windows 340 inserted into apertures 330.
[0080] As previously described, window 340 can be made of any suitable material including plastic, glass or any other transparent or translucent material through which circuit identification region 320 may be seen. In some embodiments still, window 340 could be made of an opaque material and may be removed from aperture 330 or circuit identification region 320 to view the circuit identification therebelow. Figure 9 shows a front perspective view of a face plate according to such embodiments.
[0081] Figure 16 shows another embodiment of electrical system 300 according to another aspect. In this aspect, the circuit identification region 320 is provided on one or more of the edges of the electrical system 300. In the example shown in Figure 16, the circuit identification region 320 is provided on two edges. In some embodiments, circuit identification region 320 is provided on one edge only. In some embodiments, circuit identification region 320 is provided on three edges. In some embodiments, circuit identification region 320 is provided on four edges or more.
[0082] As previously described, in some embodiments, circuit identification region 320 is provided by a recess in the face plate 200 as shown in Figure 17 and as described for example, with reference to Figures 6A, 6B and 11.In some embodiments, a window 340 is provided over this recess. In some embodiments, circuit identification region 320 is provided on a base unit or grid plate 100 below the cover unit or face plate 200, which itself is provided with an aperture 330, as shown in Figure 18, to allow the circuit identification region 320 to be viewed via the aperture 330. In some embodiments, aperture 330 is covered with a window 340, as shown in Figure 19.
[0083] Figure 20 shows an example of a base unit or grid plate 100 of the electrical system 300 shown in Figure 16. In this embodiment, circuit identification region 320 is provided on two grid edges 102. In some embodiments, circuit identification region 320 is provided on one edge only. In some embodiments, circuit identification region 320 is provided on three edges. In some embodiments, circuit identification region 320 is provided on four edges or more.
[0084] Figure 21 shows another embodiment of the grid plate 100 of the aspect of Figure 20. In this embodiment, a removable substrate or tab 400 is shown engaged with one of the circuit identification regions 320.
[0085] In some embodiments, the circuit identification region 320 has a removable substrate retaining part 321 for connecting to and retaining the removable substrate 400. In the embodiments shown, removable substrate retaining part 321 is simply a recess for receiving a corresponding engagement portion 410 of the removable substrate in a snap-fit arrangement. However, any suitable means of engaging, connecting and/or retaining the removable part may be used, including magnetic means, adhesive means, electrostatic means or “hook and loop” means.
[0086] In some embodiments, the circuit identification 320’ may be provided on the removable substrate 400 which is engaged with one or more of the circuit identification regions 320. In some embodiments, circuit identification 320’ may be directly inscribed on one or more of the circuit identification regions 320, or a label may be adhered to one or more of the circuit identification regions 320, or a combination of the various options.
[0087] Figure 22 shows the arrangement of Figure 21 but with two removable substrates or tabs 300 engaged with the circuit identification regions 320. The removable substrate or tab 400 will be described in more detail below.
[0088] Figure 23 shows another embodiment of grid plate 100, this time with windows 340 placed over the removable substrate 400/ circuit identification region 320. In some embodiments, window 340 is connected to grid plate 100. In some embodiments, window 340 is connected to face plate 200 within the aperture 330, which then covers the removable substrate 400/ circuit identification region 320 when the face plate 200 is connected to the grid plate 100 to form electrical system 300.
[0089] Figure 23 also shows user interface rockers 1201. In some embodiments, such as when used in the system described above with reference to Figures 1 to 4, user interface 1201 can be connected to the face plate or cover unit 200 to interact with interface 160 of the grid plate. In other embodiments, when a more conventional system is used, user interface 1201 forms part of a more traditional mechanism such as a switch mechanism, which itself is connected to the grid plate 100, as will be understood by the person skilled in the art.
[0090] Figures 24A, 24B, 24C and 24D show the removable substrate 400 in more detail. Figure 24A shows an embodiment of removable substrate or tab 400, which can be engaged with circuit identification region 320 as previously described. In some embodiments, removable substrate 400 comprises one or more engagement portions 410 for engaging with a corresponding removable substrate retaining part 321 of the circuit identification region 320 as previously described. While the embodiment shown here is a projection for inserting into a corresponding recess as described previously, any other suitable engagement means may be used, including magnetic means, adhesive means, electrostatic means or “hook and loop” means. In other embodiments still, engagement portion 410 may be provided by a recess, and corresponding removable substrate retaining part 321 of the circuit identification region 320 may be a projection.
[0091] In some embodiments, some reinforcing means may be provided, such as the reinforcing pattern 420 shown in Figure 24B. Figure 24C shows a side view of the removable substrate or tab 400.
[0092] Figure 24D shows an embodiment of the removable substrate or tab 400 with circuit identification 320’ displayed thereon. As will be appreciated by the person skilled in the art, the circuit identification 320’ can be provided by any suitable format, including words such as “fridge”, alpha- numeric combinations such as “DE-17” as shown in Figure 24D, colours, patterns, or any other suitable indicia that will convey identification information of the circuit with which the electrical system, base unit, cover unit, grid plate or face plate is associated.
[0093] In some embodiments, a set of removable substrates or tabs 400 may be provided, with some in the set being the same colour, and others being different colours. A specific colour of the tabs 400 can be selected and associated with a particular circuit, and tabs of that colour will be used in electrical systems 300 associated with that selected circuit. This allows a quick and convenient way for a technician to identify associated electrical systems such as power or data outlets.
[0094] According to another aspect, the provision of the removable substrate or tab 400 allows a particular grid plate or face plate to be easily updated, simply by removing an existing removable substrate or tab 400 and replacing it with a new one. This can be particularly useful if the circuit identification region 320 is on a face plate 200, which is more likely to be changed than a grid plate, particularly in the system as previously described with reference to Figures 1 to 4.
[0095] It will be appreciated that removable substrate or tab 400 may be made from any suitable material, including plastic, cardboard, metal and wood.
[0096] Furthermore, the use of the removable substrate or tab 400 allows easy replacement of existing circuit identifications 320’ that may have become damaged.
[0097] Broadly then, there is also provided a method of providing a circuit identification to an electrical system, the method comprising engaging a removable substrate or tab bearing the circuit identification, with a circuit identification region of the electrical system. In some embodiments, the step of engaging comprises inserting an engagement portion of the removable substrate or tab with a corresponding removable substrate retaining part of the electrical system.
[0098] Figure 25 shows an embodiment of an electrical system 300 comprising various aspects described herein. Electrical system 300, in this case a power outlet, comprises grid plate 100 (not visible in this view), face plate 200, comprising power sockets 310 and user switch interfaces (rockers) 1201, as well as apertures 330. Apertures 330 allow visibility of the circuit identification region 320 on the grid plate 100, with which removable substrate or tab 400 is engaged. Removable substrate or tab 400 clearly displays circuit identification 320’ in the form of the alphanumeric code “DE-17”, identifying a particular circuit, with which the power outlet 300 is associated.
[0099] Because the circuit identification 320’ is recessed from the surface of the outlet 300, it is less likely to be damaged. Of course, further protection can be provided in some embodiments by the provision of window 340 in aperture 330.
[00100] Throughout the specification and the claims that follow, unless the context requires otherwise, the words “comprise” and “include” and variations such as “comprising” and “including” will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.
[00101] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement of any form of suggestion that such prior art forms part of the common general knowledge.
[00102] It will be appreciated by those skilled in the art that the invention is not restricted in its use to the particular application described. Neither is the present invention restricted in its preferred embodiment with regard to the particular elements and/or features described or depicted herein. It will be appreciated that the invention is not limited to the embodiment or embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the invention as set forth and defined by the following claims.
