Abstract

A dusting device is provided that has at least one cleaning member with a microfiber bundle secured to a spine by a seam. The spine provides a resilient flexibility to the cleaning member such that the spine flexes as pressure is applied, but at least partially returns to an original shape upon removal of the pressure.

First claim

What is claimed is:

1. A dusting device comprising,
at least one cleaning member having a spine and a bundle of loose microfiber segments, the loose microfiber segments being secured only to one another to form said bundle, said bundle being secured to only one side of said spine by a seam, said spine providing a resilient flexibility to said at least one cleaning member such that said spine flexes as pressure is applied, but at least partially returns to an original shape upon removal of said pressure; and
wherein said at least one cleaning member comprises a plurality of cleaning members.

2. The dusting device of claim 1 , wherein said spine has a cross sectional shape selected from the group consisting of a substantially polygonal cross section, a circular cross section, an ovoid cross section, a star shaped cross-section having a core with a plurality of evenly spaced or unevenly spaced radially extending members, and any combinations thereof.

3. The dusting device of claim 1 , wherein said loose microfiber segments of said bundle are directly secured to one another by another seam.

4. The dusting device of claim 1 , further comprising a span control member slideably disposed over said plurality of cleaning members for movement between a first position and a second position.

5. The dusting device of claim 4 , wherein said plurality of cleaning members are normally biased to a spread apart position when said span control member is in said first position, said span control member restraining said plurality of cleaning members when in said second position.

6. The dusting device of claim 1 , wherein said seam is selected from the group consisting of a sewn seam, a glued seam, a welded seam, a woven seam, and any combinations thereof.

7. The dusting device of claim 1 , wherein said loose microfiber segments comprise fibers having a denier of less than one.

8. The dusting device of claim 1 , wherein said spine has a flat elongated shape.

9. The dusting device of claim 1 , further comprising a plurality of microfiber bundles secured to said spine by said seam.

10. The dusting device of claim 1 , wherein said plurality of cleaning members each comprises a plurality of spines integrally formed with one another.

11. The dusting device of claim 1 , further comprising a handle connected to said at least one cleaning member.

12. The dusting device of claim 11 , wherein said handle is releasably connected to said at least one cleaning member.

13. The dusting device of claim 11 , wherein said spine is part of a spine assembly, said spine assembly comprising:
a plurality of said spines;
a base portion having said plurality of spines extending therefrom; and
a pair of interlocking features releasably securing said base portion to said handle.

14. A dusting device comprising:
a plurality of elongated spines;
a base portion having said plurality of elongated spines extending therefrom; and
a plurality of microfiber bundles, each bundle of said plurality of microfiber bundles comprising a plurality of microfiber segments secured to one another by a first seam, and each bundle of said plurality of microfiber bundles being secured to a different one of said plurality of elongated spines by a second seam,
wherein said spines are resiliently flexible such that said spines flex as a pressure is applied, but at least partially return to an original shape upon removal of said pressure.

15. The dusting device of claim 14 , further comprising a feature on said base portion to releasably secure said base portion to a handle.

16. The dusting device of claim 14 , wherein each spine of said plurality of elongated spines has a cross sectional shape selected from the group consisting of a substantially polygonal cross section, a circular cross section, an ovoid cross section, a star shaped cross-section having a core with a plurality of evenly spaced or unevenly spaced radially extending members, and any combinations thereof.

17. The dusting device of claim 14 , wherein said second seam is a sewn seam.

18. The dusting device of claim 14 , wherein said microfiber bundle comprises a plurality of fibers having a denier of less than one.

19. The dusting device of claim 14 , wherein each spine of said plurality of elongated spines comprises a material selected from the group consisting of nylon, polyethylene, polypropylene, thermoplastic elastomer (TPE), thermoplastic rubber (TPR), silicone rubber, hard durometer rubbers, foam, acetal, and any combinations thereof.

20. A dusting device comprising,
at least one cleaning member having a spine and a bundle of loose microfiber segments, the loose microfiber segments being secured only to one another to form said bundle, said bundle being secured to only one side of said spine by a seam, said spine providing a resilient flexibility to said at least one cleaning member such that said spine flexes as pressure is applied, but at least partially returns to an original shape upon removal of said pressure; and
wherein said spine comprises a material selected from the group consisting of nylon, polyethylene, polypropylene, thermoplastic elastomer (TPE), thermoplastic rubber (TPR), silicone rubber, hard durometer rubbers, foam, acetal, and any combinations thereof.
