Detailed Description of the Preferred Embodiment

[0045] A novel wireless charging system will be described hereinafter. Although the invention is described in terms of specific illustrative embodiments, it is to be understood that the embodiments described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.

[0046] Illustrated on Figures 1 and 8C is an inductively coupled charging system 100 with integrated primary coils embedded on the top surface S of a furniture F, such as the top surface of a counter of a bar as illustrated. Power is inductively coupled from the top surface S with the integrated primary coil to an electronic smartdevice D, such as a smartphone, a cell phone, a smartwatch, a tablet, a phablet, a laptop computer, a power tool or other handheld devices that have wireless charging capabilities typically embodied as a secondary coil. The inductively coupled work surface may alternatively be installed at the top surface of other furniture such as tables, counters in restaurants or home kitchen, furniture in hotel bed rooms, etc. Primary coils integrated into a work surface may provide varying amounts of power. Smartdevices D containing secondary coils, such as laptop computers, PDAs, cell phones, and power tools, are charged when placed on the top surface S where primaiy coils are integrated.

[0047] As illustrated on Figures 2, 3A, 8A and 8B, the charging system 100 for wirelessly charging a smartdevice D when the smartdevice is positioned over the charging system comprises a charger 110 connectable to an electrical power source (not illustrated) for charging the smartdevice. The charger 110 is configured in size to be inserted inside the furniture F through an opening 200 located at the top surface S of the furniture F. Any sort of primary coil charger known in the art can be used within the scope of the present invention.

[0048] The system 100 further comprises a fixing element 120 configured for fitting with the opening 200. Although the invention described herein shows a circular opening and a fixing element 120 being a ring fitting with the circular opening, different geometries of the opening can be considered within the scope of the invention, inasmuch as the charger can be affixed to the fixing element and can be inserted through the opening. As illustrated in the figures, the fixing element is preferably a ring and the removable cap is preferably a disc adapted to be inserted into the top recess of the ring. The ring is more preferably made of stainless steel but other material may be used within the scope if the invention, such as plastic, wood, etc.

[0049] As illustrated on Figures 8A and 8B, the fixing element 120 is affixed to the charger. The charger can be suspended inside the opening and retained by the fixing element. Alternatively, the charger can be affixed inside the opening ring other internal fixing elements (not illustrated).

[0050] As illustrated on Figures 2, 3A and 4B, the fixing element may be affixed to the charger 110 using another adhesive element 150.

[0051] Alternatively, the fixing element can be affixed to the charger 110 by screwing the fixing nng 120 to the charger 110 as illustrated on Figures 9, 10A, 10B, 10C, 11A and 1 IB. The fixing element 120 then further comprises a threaded internal potion 190 and the charger comprises an external threaded portion 112. The fixing element 120 can be then screwed to the charger 110 before being inserted into the opening of the furniture.

[0052] The system 100 further comprises a removable cap 130 having a top 131 and a bottom 132 surface, the cap 130 being configured for capping the fixing element and covering the charger 110 located inside the furniture F. As illustrated on Figures 2, 3 A, 3B, 4A and 4B, the fixing element 120 defines atop recess 121 configured for receiving the removable cap 130. The top recess 121 may comprise an adhesive material 140 (Fig.2 or 3 A), such as a double face tape, for affixing the removable cap to the fixing element. The adhesive property of the adhesive material also allows the cap 130 to be removed from the fixing element when need be.

[0053] As illustrated on Figures 5A or 5B, the removable cap 130 may be a disc with a squared edge fitting with a squared cross section of the top recess 121 of the fixing element 120. According to another embodiment illustrated on Figures 6A, 6B or 6C, the cap 130 may have a truncated edge fitting with a truncated cross section of the top recess 121. Compared to the squared shape of Figure 5A or 5B, the truncated shape of Figures 6A-6C provides a greater contacting surface between the cap and the recess 121 of the fixing element 120, and also ease the insertion of the cap into the top recess of the fixing element.

[0054] The adhesive element 160 may also plays the role of a waterproof seal 160 located between the bottom surface 122 of the lip 120 of the fixing element and the top surface S of the furniture F adjacent to the opening 200 (Fig. 4B). The seal protects the electronic charger 110 embedded into the furniture F from water or other liquid that can be spread by accident on the top surface S.

[0055] As illustrated on Figures 2, 3A, 4A to 6C, the fixing element comprises an external lip 122 for abutting the edge of the opening 200 when the fixing element 120 is inserted into the opening 200. The external lip may define different geometries, such as a squared lip (Fig. 5A or 6A), a triangular or truncated lip (Fig. 4A, 4B or 6B) or a round lip (Fig. 5B or 6C) for providing a smooth transition from the top surface of the fixing element to the top surface of the furniture as illustrated on Figure 8C. Other non- illustrated forms for the lips can be considered within the scope of the present invention.
