1. Field of the Invention
The present disclosure is related to dusting devices. More particularly, the present disclosure is related to dusting devices with cleaning members that are flexible, washable, and reusable.
2. Description of Related Art
The recurring need to remove dust from various surfaces in residential and/or commercial settings has led to a variety of hand held dusting devices being developed to accomplish this task. Some common prior art hand held dusting devices range from simple devices, such as a dusting rag, to more elaborate devices such as hand held feather dusters. Each of these prior art hand held dusting devices provide different advantages and/or disadvantages to the user.
More recently, hand held dusting devices consisting of a handle with a cleaning pad removably secured thereon have been introduced. In many examples, the removable cleaning pad is made of non-woven polymeric materials. When using these prior art devices, the non-woven polymeric cleaning pads, once soiled, must be removed from the handle and replaced with a new cleaning pad. The cost and/or perceived environmental impact of constantly replacing the non-woven cleaning pad may reduce the appeal of such hand held dusting devices to some consumers.
Accordingly, it has been determined by the present disclosure that there is a need for hand held dusting devices that overcome, alleviate, and/or mitigate one or more of the aforementioned and other deleterious effects of the prior art.
A hand held dusting device is provided that includes a flexible spine with a washable and reusable cleaning member permanently secured thereon. The cleaning member is comprised of a microfiber bundle, which when combined with the spine allow the dusting device to function in a similar, but improved, manner as common feather dusters. Thus, the microfiber bundle and spine combine to form a flexible, washable, and reusable “microfiber feather”, which provides the dusting device of the present application with the enhanced dust collection functionality of typical microfiber fabrics.
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.
A method of forming a flexible, washable cleaning member for a dusting device is also provided. The method includes bonding a length of microfiber to itself by a first seam; trimming the microfiber to divide the length of microfiber into a plurality of segments secured together by the seam to define a microfiber bundle; fluffing the microfiber bundle to provide loft and separation between the plurality of segments; and securing the microfiber bundle to a flexible spine by a second seam.
The above-described and other features and advantages of the present disclosure will be appreciated and understood by those skilled in the art from the following detailed description, drawings, and appended claims.
Referring to the drawings and in particular to
Cleaning member 14, also referred to herein as a “microfiber feather”, is an assembly of a microfiber bundle 16 with a flexible spine 18 as shown in
As used herein, the term “seam” shall mean any continuous or non-continuous connection between microfiber bundle 16 and flexible spine 18. Seam 20 can be a sewn seam, a glued seam, a welded seam, woven seam, and any combinations thereof.
Bundle 16 is formed of a fiber 22, which is cut into a plurality of segments. In a preferred embodiment, fiber 22 is a microfiber. As used herein, the term “microfiber” shall mean a fiber having a denier of less than one. In some embodiments, fiber 22, when the fiber is a microfiber, is made of a blend of about 75% polyester (PE) and about 25% polyamide (PA) having a denier of about 0.138.
Spine 18 is configured to provide a resilient flexibility to cleaning member 14. Namely, spine 18 bends as pressure is applied during dusting, but at least partially returns to its original shape upon removal of the pressure. Additionally, spine 18 is preferably made of a non-scratch material so that cleaning member 14 can be used on a variety of delicate surfaces. For example, it is contemplated by the present disclosure for spine 18 to be made of nylon, polyethylene, polypropylene, thermoplastic elastomer (TPE), thermoplastic rubber (TPR), silicone rubber, hard durameter rubbers, foam, acetal, and can be fabricated by any suitable method such as, but not limited to, injection molding, compression molding, die cutting, and others. It is also contemplated by the present disclosure for spine 18 to be formed of metallic materials such as spring steel or a core of twisted wire (e.g. pipe cleaner material). Of course, any material or combinations thereof that provide the desired flexibility, washability, and non-scratchability are sufficient.
Spine 18 can have any desired cross section that are sufficient to provide the desired flexibility, washability, and non-scratchability. For example, spine 18 can have a substantially polygonal cross section including triangular, rectangular, or as many sides as desired, a substantially circular or 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.
Advantageously, cleaning member 14 is flexible, washable, and reusable. As used herein, the term “washable” shall mean that the microfiber feather, and when necessary other components of the dusting device, can be washed in a cleaning solution such as water and/or detergent either by hand or in a washing machine such as, a laundry washing machine and a laundry drying machine.
Bundle 16 is described with simultaneous reference to
It should be recognized that bundle 16 is described by way of example only as being constructed with microfiber 22 folded to a single, constant width 26 along length 24. Of course, it is contemplated by the present disclosure for bundle 16 to be constructed with width 26 that varies along length 24. It should also be recognized that bundle 16 is described by way of example only as being constructed with microfiber 22 folded so that width 26 is symmetrical about a central axis 28 of the bundle. Of course, it is contemplated by the present disclosure for bundle 16 to be constructed with width 26 that is non-symmetrical about central axis 28.
Once folded to the desired length 24, the various portions of microfiber 22 in bundle 16 are joined by a seam 30. In the illustrated embodiment, seam 30 is defined along central axis 28. Of course, it is contemplated by the present disclosure for seam 30 to be defined in any desired position on bundle 16. One having ordinary skill in the art can appreciate that the various portions of fiber 22 of bundle 16 and seam 20 can be fabricated by a continuous feeding process. That is, seam 20 can join the various portions of fiber 22 as the length of the fiber is repeatedly folded upon itself. This allows bundle 16 the option of being cut to any desired length 24.
Once secured together by seam 30, loops 32, which are formed by the folds of fiber 22, are cut so that the microfiber is divided into a plurality of segments 34. Thus, in
In some embodiments, bundle 16 can include one or more cut-guiding seams 36 (two shown on each side of axis 28). Cut-guiding seams 36 have been found by the present disclosure as being advantageous to maintain fiber 22 in a desired position to ensure that each loop 32 is cut. After cutting loops 32, cut-guiding seams 36 are removed so that segments 34 move freely about their connection at seam 30.
It should be recognized that bundle 16 is described by way of example only as being constructed with fiber 22 coiled to a single, constant width 26 along length 24. Of course, it is contemplated by the present disclosure for bundle 16 to be constructed with width 26 that varies along length 24. It should also be recognized that bundle 16 is described by way of example only as being constructed with fiber 22 coiled so that width 26 is symmetrical about central axis 28 of the bundle. Of course, it is contemplated by the present disclosure for bundle 16 to be constructed with width 26 that is non-symmetrical about central axis 28.
Once coiled to the desired length 24, the various portions of fiber 22 in bundle 16 are joined by seam 30. In the illustrated embodiment, seam 30 is defined along central axis 28. Of course, it is contemplated by the present disclosure for seam 30 to be defined in any desired position on bundle 16 and can be formed by a continuous feeding process as detailed above.
Once secured together by seam 30, coils 32′, which are formed by the repeated coiling of fiber 22, are cut so that the microfiber is divided into two different plurality of segments 34. Thus, in
In some embodiments, bundle 16 can include one or more cut-guiding seams 36 (two shown on each side of axis 28), which are removed after cutting so that segments 34 move freely about their connection at seam 30 as discussed above.
Again, it should be recognized that bundle 16 is described by way of example only as being constructed with two microfibers 20 folded to a single, constant width 26 along length 24 and having the microfibers folded so that width 26 is symmetrical about a central axis 28 of the bundle. Of course, any desired configuration is contemplated by the present disclosure.
Once folded to the desired length 24, the various portions of microfibers 20 in bundle 16 are joined by a seam 30. In the illustrated embodiment, seam 30 is defined along central axis 28. Of course, it is contemplated by the present disclosure for seam 30 to be defined in any desired position on bundle 16 and can be formed by a continuous feeding process as detailed above.
Once secured together by seam 30, the outermost loops 32″, which are formed by the folds of microfibers 20, are cut so that the two microfibers are divided into plurality of segments 34. Thus, in
In some embodiments, bundle 16 can include one or more cut-guiding seams 36 (two shown on each side of axis 28). Cut-guiding seams 36 have been found by the present disclosure as being advantageous to maintain fiber 22 in a desired position to ensure that each outermost loop 32″ is cut. After cutting loops 32″, cut-guiding seams 36 are removed so that segments 34 move freely about their connection at seam 30. It should be noted that loops 32 can be cut between cut-guiding seams 36 so that one of the cut-guide seams remains with the cut loop, while the other of the cut-guiding seam remains on the segments for later removal. If desired, loops 32 can be cut on either side of cut-guiding seams 36.

Returning now to
In some embodiments, handle 12 can be configured so that the entire dusting device 10 can be placed in the washing machine. However, it is also contemplated by the present disclosure for connection device 38 to removably connect cleaning members 14 to handle 12. In this manner, cleaning members 14 can be removed from handle 12 for washing and drying.
In the embodiment shown in
In some embodiments, second portion 42 maintains cleaning members 14 connected to one another such that a subassembly 44, consisting of the cleaning members and the second portion 42, can be removed from handle 12 for washing and drying. Thus, in this embodiment, at least cleaning members 14 and second portion 42 of dusting device 10 are washable. However, it should also be noted that cleaning members 14 can also be removed in individual manner (i.e. the ability of removing each cleaning member 14 seperately) to perform a washing/drying operation.

For example, hinge member 72 can be a ball-and-socket hinge 74 that provides a limited range of motion 76. Alternately, hinge member 72 can be a living hinge 78 defined in spine 18 by weakening the spine in one or more locations. The living hinge 78 can be provided by narrowing the thickness of the spine, adding one or more openings through the spine, or any other method to locally weaken the spine to bending. Of course, the present disclosure contemplates any other type of hinge member 72 is suitable to provide one or more regions of enhanced flexibility to spine 18.
