Abstract

Furniture components, such as office furniture components, are configured to include electronic components that transfer electrical power to peripheral electronic devices via wireless technologies, including conductive and inductive technologies. The articles of furniture may include grommet devices received within work surfaces, the grommet devices incorporating or housing the electronics of wireless power systems. The articles of furniture may also include the electronics of wireless power systems physically embedded or integrated within work surfaces in a manner in which the continuous surfaces of the work surfaces are maintained, and the work surfaces may optionally further include lighting or other indication features to indicate the locations of the electronics to a user.

Claims (27)

1. A furniture component for use in inductively transferring power to an electronic device that includes a secondary coil of an inductive coupling, the furniture component comprising:

a work surface having an uninterrupted and continuous upper surface, a lower surface disposed opposite and below said upper surface, and an intermediate portion disposed between said upper and lower surfaces;

a primary coil mounted to said lower surface, said primary coil operable to induce a current in the secondary coil when the electronic device is positioned proximate said upper surface and above said primary coil.

2. The furniture component of claim 1 , wherein said lower surface includes a cavity extending into said intermediate portion of said work surface without extending through said upper surface, said primary coil positioned within said cavity and disposed proximal to said upper surface.

3. The furniture component of claim 1 , wherein said work surface is made at least in part of a translucent material.

4. The furniture component of claim 1 , wherein said work surface is made at least in part of a thermoplastic selected from the group consisting of an acrylic, polypropylene, and a combination thereof.

5. The furniture component of claim 4 , wherein said work surface further comprises a filler material.

6. The furniture component of claim 1 , wherein said work surface is made at least in part of acrylic with alumina trihydrate filler.

7. The furniture component of claim 1 , further comprising at least one illumination marker disposed beneath said upper surface, said illumination marker illuminating through a portion of said upper surface to indicate a location of said primary coil.

8. The furniture component of claim 7 , comprising a plurality of said illumination markers arranged to form an illuminated pattern.

9. The furniture component of claim 7 , wherein said at least one illumination marker is spaced from said primary coil.

10. A furniture component for use in inductively transferring power to an electronic device that includes a secondary coil of an inductive coupling, the furniture component comprising:

a work surface formed at least in part of a translucent material and having an uninterrupted and continuous upper surface, a lower surface disposed opposite and below said upper surface, and an intermediate portion disposed between said upper and lower surfaces;

a primary coil mounted to said lower surface and operable to induce a current in the secondary coil when the electronic device is positioned proximate said upper surface and above said primary coil; and

at least one illumination marker disposed beneath said upper surface and spaced from said primary coil, said illumination marker illuminating through said translucent material of said upper surface to indicate a location of said primary coil.

11. The furniture component of claim 10 , wherein said translucent material is a thermoplastic selected from the group consisting of acrylic, polypropylene, and a combination thereof.

12. The furniture component of claim 11 , wherein said translucent material further comprises a filler material.

13. The furniture component of claim 10 , comprising a plurality of said illumination markers arranged to form an illuminated pattern.

14. The furniture component of claim 10 , wherein said lower surface includes a cavity extending into said intermediate portion of said work surface without extending through said upper surface, said primary coil positioned within said cavity and disposed proximal to said upper surface.

15. A furniture component for use in inductively transferring power to an electronic device that includes a secondary coil of an inductive coupling, the furniture component comprising:

a work surface having an uninterrupted and continuous upper surface, a lower surface disposed opposite and below said upper surface, and an intermediate portion disposed between said upper and lower surfaces;

said lower surface including a cavity extending into said intermediate portion of said work surface without extending through said upper surface;

a primary coil positioned within said cavity and operable to induce a current in the secondary coil when the electronic device is positioned proximate said upper surface and above said primary coil; and

at least one illumination marker disposed beneath said upper surface and spaced from said primary coil, said illumination marker illuminating through a portion of said upper surface to indicate a location of said primary coil.

16. The furniture component of claim 15 , wherein said work surface is made at least in part of a translucent material, said at least one illumination marker operable to transmit light through said translucent material.

17. The furniture component of claim 16 , wherein said translucent material is a thermoplastic selected from the group consisting of an acrylic, polypropylene, and a combination thereof.

18. The furniture component of claim 15 , comprising a plurality of said illumination markers arranged to form an illuminated pattern.
