Within this specification, the term about means plus or minus 20%, more preferably plus or minus 10%, even more preferably plus or minus 5%, most preferably plus or minus 2%.

Within this specification, reference to one or more preferably includes all.

With reference to Figures 1 to 3, different examples of a table 2 comprising a rechargeable leg 1 are provided. In each example, the leg 1 is attached to a table top 3 at one end and a base 4 at the other end. In Figures 1 and 2, power outlets 5 from a rechargeable power source 6 (see Figures 4 to 7) are provided on a dome 7 in the centre of the table top 3. In Figure 3, access to power outlets is via a removable top disc 11 provided in the centre of the table top 3 with the power outlets provided in a recess (not shown) in the top of the leg 1. For example, USB cables 27 and/or power cables 28 could be provided which could be pulled out ofthe recess, through apertures 29, when in use.

The example shown in Figure 1 includes a power inlet socket 8 for providing power to the rechargeable power source 6. The example shown in Figure 2 includes a plug 9 for connection to a mains power socket (not shown) for providing power to the rechargeable power source 6.

Also shown in Figures 1 to 3 is an on/off switch 10 and power indicator light 13 are provided on the table top 3. The power indicator light 13 and on/off switch are connected to the leg 1 via cables (not shown). It will also be appreciated that the on/off switch 10 and power indicator light 13 could be provided on the leg 1. Also provided is a battery charging indicator 26 which lights up when the power source 6 is being recharged. In the example shown, an amber light is displayed during charging and a green light is displayed when the power source 6 has been fully charged.

The leg 1 is provided with a plurality of power outlets 5, an on/off power switch 10 and a power inlet 8, 9 for receiving mains power to charge the power source

6. The rechargeable power source 6 is in electrical communication with the power inlet 8, 9 and is in electrical communication with the power outlets 5 via the power switch.

The housing 21 comprises a cylindrical body of circular section on which the power inlet 8, 9 is located. The rechargeable power source 6 is provided in the internal space defined by the housing 21.

As will be appreciated, when the leg 1 is connected to a table top 3, the power outlets 5 can be presented to a user via a removable disc 11 in the table top 3 (Figure 3) or the leg 1 can extend through the table top 3 to provide a tower or via the side of the leg 1 below the table top 3 or dome with power outlets 5 provided thereon (Figures 1 and 2). Alternatively, the leg 1 can be affixed to the underside of a table top 3 with the power outlets 5 accessible from under the table top 3 with apertures (not shown) provided in the table top 3 through which cables (not shown) can be inserted.

Portions of the leg 1 which remain visible may be selected so as to match the appearance of the furniture item. For example, the appearance (colour, finish, material, patterning etc.) of the leg 1 and/or the disc 11 may be selected to match the appearance of the table top 3.

Power may be supplied to electronic or electrical devices (for example, portable electronic devices such as laptops, notebooks, Chromebooks (RTM), ultrabooks, tablets, mobile telephones, any USB chargeable device and the like) located on or in the vicinity of the leg 1 simply by electrically connecting those devices to a respective one of the power outlets 5, for example by plugging a lead connected with the device into one of the power outlets 5, which power outlet will then supply electrical power from the rechargeable power source 6 to the device.

Power will continue to be supplied to the one or more connected devices until the rechargeable power source 6 is switched off manually, remotely or automatically by the timed switch or until the rechargeable power source 6 is expended.

The rechargeable power source 6 may be recharged for re-use by supplying electrical power to the rechargeable power source 6 via the electrical power inlet 8,9.

This may be achieved by connecting a power supply (e.g. a mains extension lead) directly to the electrical power inlet 8. In embodiments which employ lithium battery technology, charging can take as little as 1 or 2 hours. In addition, the use of lightweight high capacity lithium batteries means that the leg 1 can be easily moved to a recharging socket. This can be aided further by the provision of wheels (not shown) on the leg 1 or legs 1.

The rechargeable power source 6 may comprise one or more rechargeable batteries 6A, 6B, 6C, 6D constructed from one or more cells, which one or more batteries may be of any suitable variety (e.g. Lead Acid, NiMH, NiCD, Lithium etc.) and capacity for the intended application of the leg 1.

Similarly, the power outlets 5 may be of any suitable form. In the examples shown in Figures 1 and 2, each of the power outlets 5 comprises a mains power socket, but other power outlets (e.g. a Universal Serial Bus (USB) power socket) may be employed. The leg 1 may also be provided with one or more DC power outlets with voltages (and connectors as necessary) specific to laptop type devices where laptop device input voltages range from e.g. 9V to 20V (often

19V). In a further alternative, the leg 1 may be provided with a combination of differing power outlets e.g. two USB power sockets and one mains power socket. Further, the leg 1 may be provided with any desired number of power outlets; it is envisaged that a plurality of power outlets 5 would be most preferable to permit power to be simultaneously supplied to a plurality of devices, but a leg 1 having a single power outlet could also be provided.

Further, the leg 1 may be provided with any suitable circuitry to provide electrical power at its one or more power outlets 5 in any desired form. For example, the circuitry of the leg 1 may comprise a voltage converter to provide power via the one or more power outlets 5 at a desired voltage level; similarly, the leg 1 may comprise a voltage inverter to provide AC power at the one or more power outlets 5.

The leg 1 may comprise additional circuitry components. For example, the leg 1 may comprise low voltage disconnect circuitry and/or a power indicator light 13, lights, gauge or LCD to indicate the status of the rechargeable power source 6, such as the level of charge remaining, and/or to indicate when the rechargeable power source 6 is being recharged. As a further example, the leg 1, and/or the furniture item (e.g. table 2) of which the leg 1 forms a part of, may be provided with a solar panel to supply recharging power to the rechargeable power source

6. Furthermore, it will be envisaged that wireless charging technology could be included, for example in the form of a wireless inductive power charging mat.

In the examples shown, the power switch 10 is operable to interrupt the supply of power from the rechargeable power source 6 to all of the power outlets 5 of the leg 1. However, a plurality of power switches may instead be provided, each to interrupt the supply of power to a respective one of a corresponding plurality of power outlets 5. The power switch 10 may be connected to timing electronics and relays in order to only provide power to some or all of the power outlets 5 for a definable period of time.

With reference to Figures 4 and 5, the internal scaffold 12 is shown on which internal components such as sections of the rechargeable power source 6A, 6B, 6C and a communications device 14 are supported. The scaffold 12 is connected to a base 4.

With particular reference to Figure 5, the scaffold 12 comprises metal bars 16 and cross plates 17. The cross plates 17 comprise protrusions 18 for engagement with holes 19 in the metal bars 16. The cross plates 17 also comprise holes 20 through which screws (not shown) can be inserted and screwed into corresponding holes (not shown) on the internal components 6A, 6B, 6C, 14.

As shown in Figures 6, 8A and 8B, the leg 1 includes a housing 21 with double/combined channels 22 for holding the metal bars 16 and for receiving a plurality of screws. Each double/combined channel 22 includes first 22A and second 22B channels separated by a wall 22C. The first channel 22A is for housing a metal bar 16. The second channel 22B is a screw-receiving channel.

Additional screw-receiving channels 22B are provided within the housing 21 which are not adjacent a metal bar (support) channel 22A.

Each screw-receiving channel 22B comprises an elongate channel with an opening 23 for receiving a plurality of screws (not shown), said opening 23 extending along the channel 22B for receiving screws from within the housing. This allows screws to be screwed into the channel 23 from within the internal space defined by the housing 21.

The end of the screw-receiving channel 22B comprises an open end 24 for receiving a screw from outside the housing 21. Accordingly, not only can the screw-receiving channels 22B receive screws from within the housing 21, for example screws which are used to secure internal components to the inside face of the housing, but the screw-receiving channels 22B can also aid construction of a furniture item using the leg 1. For example, it will be envisaged that a table top 3 could be secured to the leg 1 by passing one or more screws through the table top 3 and into the end 24 of one or more screw-receiving channels 22B to secure the table top 3 to the leg 1. Corresponding ends 24 of the screwreceiving channels 22B are provided at the other end of the housing 21 for connection to, for example, a base 4.

With reference to Figure 7, the housing 21 can be slid over the scaffold 12 and into engagement with the base 4 and scaffold 12. This then hides the scaffold 12 and the internal components 6A, 6B, 6C, 6D, 14 supported thereon within the housing 21. The housing 21 is placed into slideable engagement with the scaffold 12 by aligning the metal bars 16 with the support channels 22A and then sliding the support channels 22A onto the metal bars 16.

It will be appreciated that housings 21 of differing height can be used with a single scaffold 12. In this respect, it is not necessary for the metal bars 16 of the scaffold to extend all the way to the top of the housing 21. Accordingly, this allows for the provision of a modular system with not only the ability to easily change the external appearance of the leg 1 via the use of different coloured housings 21, but also to easily change the height of the leg 1 and thus a furniture item 2 of which the leg 1 forms a part without replacing the entire leg

1. This is particularly advantageous since all the electrical components can be provided on the scaffold 12 which means that it is only necessary to change the housing 21 if a different appearance and/or height of leg is required whilst wishing to retain the original functionality. This also makes manufacture of legs 1 according to the invention much easier.

As described herein, the rechargeable leg of the present invention has a number of advantageous features.

Rechargeable batteries and electrics can be integrated into one or more table legs to provide power to electrical and electronic devices. This means that the tables can be used in locations with no mains power sockets.

A modular construction is provided which allows different battery capacities, types and numbers of batteries, different power conversion electronics (AC and DC conversion), different power socket types and quantities, and different table/furniture heights, designs and configurations to be provided.

The leg can be manufactured in a variety of lengths and widths and so used to construct tables and other furniture of different sizes and heights.

One or more power outlets can be provided, with options of mains, USB, DC for laptops and other power types.

The provision of lithium battery technology or similar with fast charge capability (e.g. 1 to 2 hours) means that an extension lead can be used for a short period of time to recharge the table/furniture item, although other battery technologies such as Lead Acid can also be utilised.

The use of lightweight high capacity lithium batteries means that a table/furniture item incorporating one or more of the legs is light enough to be wheeled or moved to a recharging socket.

The use of large battery capacities can provide over 1000 Wh of power.

The configurable internal design using a specially designed extruded tube with internal scaffold tower to mount and retain batteries, electrics and other components is particular advantageous.

Also provided is the option to connect, store and hideaway user device adapters and cables within the leg, for example via the provision of internal sockets.

Push to start, variable timed power-on electronics can be included so power automatically starts and/or shuts off after a pre-determined amount of time to prevent unnecessary battery discharge.

The ability to remotely manage and monitor the rechargeable leg using wireless communication and web and/or mobile device based applications provides particularly useful advantages. The functionality of this technology can include the ability to manually and/or automatically remotely power off of the leg, indicate charge level status, provide usage statistics and provide information regarding the identity of a furniture item and/or location of a furniture item incorporating one or more of the legs.

The leg provides the ability to power display screens, mobile and desktop computers, projectors and other IT equipment.

The leg can also be configured as a local back up power solution for critical use scenarios in the event of mains power loss, for example like a UPS (uninterruptible power supply) for a server but integrated into the leg.

The inclusion of a pop-up centre, for example using a gas strut to reveal power sockets and provide adapter/cable storage is particularly advantageous. The pop-up centre can be pushed down to hide it away.

Other powered electrical devices can be provided within the leg, for example a local Wi-Fi booster, Wi-Fi hub, Wi-Fi router with integral Ethernet switch, and so on.

The leg can be provided with a battery charge gauge.

Power and/or data cables, including a charging power lead, can be retractable back into leg, for example using sliding weights, in a sprung loaded fashion or just manually.

Wireless inductive charging pads can be provided on the leg or on another part of a furniture item to which the leg is connected, for example integrated into the surface of a table top.

Solar panels for recharging the power source can be provided on the leg or on another part of a furniture item to which the leg is connected, for example integrated into the surface of a table top.

It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. It is therefore intended that such changes and modifications are covered by the appended claims.
