Patent Application
20130205522
The field of this invention is personal care products and specifically to lint removal devices.
The field of lint removal devices has seen various embodiments from hand formed folds of tape to bristle brushes. Conventional lint rollers include a handle, a tape roll support extending from the handle, and a roll of tape rotatably mounted on the support. The user rolls the tape (having an adhesive side facing outwardly) over the surface to be cleaned, and debris (e.g. lint, hair, etc.) is adhered to the tape thus lifting it off of the surface being cleaned. One problem with conventional lint rollers is that some debris is difficult to remove from the surface to be cleaned (i.e. the tape adhesive is not strong enough to separate the debris from the surface).
The present invention solves the aforementioned problem by providing a debris agitator integral to the lint roller assembly.
The cleaning apparatus includes a handle with a first end and a second end, a cleaning roll support extending from the handle second end and terminating at a distal end, an agitator arm extending from the handle second end parallel to the cleaning roll support and terminating at a distal end and an end cap rotatably connected to the agitator arm distal end. The end cap is configured to be rotatable between an open position away from the cleaning roll support and a closed position in which the end cap engages with the distal end of the cleaning roll support.
Other objects and features of the present invention will become apparent by a review of the specification, claims and appended figures.
For a better understanding of the embodiments described in this application, reference should be made to the Detailed Description below, in conjunction with the following drawings in which like reference numerals refer to corresponding parts throughout the figures.
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a sufficient understanding of the subject matter presented herein. But it will be apparent to one of ordinary skill in the art that the subject matter may be practiced without at least some of these specific details. Moreover, the particular embodiments described herein are provided by way of example and should not be used to limit the scope of the invention to these particular embodiments. In other instances, well-known components have not been described in detail so as not to unnecessarily obscure aspects of the embodiments of the invention.
An end cap 160 is rotatably attached or formed to the end of the agitator arm 140 via a hinge 170. Hinge 170 can be any conventional hinge allowing end cap 160 to rotate relative to arm 140. In the embodiment shown, the hinge 170 between the end cap 160 and the end of agitator arm 140 is a living hinge, which is a thin deformable section of material allowing the end cap 160 to rotate relative to arm 140 by flexing the material that forms the hinge. The end cap 160 includes a flat section 161 and an annular shoulder 162 dimensioned to snugly fit into the circular open end 130 of the support 120.
Once the cleaning roll 150 is slid onto the support 120, the end cap 160 can be rotated down until the annular shoulder 162 engages with the open end 130 of the support 120 (i.e. a friction fit) via the living hinge 170. Once engaged it its (closed) position, the end cap 160 serves several purposes, including: 1) preventing the roll of tape 150 from inadvertently sliding off of the support 120 during use, and 2) provide mechanical support for the agitator arm 140 (i.e. to prevent the arm 140 from being deflected or bent during use). The agitator arm 140 includes an agitator 141 made of any material that effectively loosens debris from surfaces. For example, agitator 141 can be ribs (see for example
In operation, the user rubs the agitator 141 on the surface to be cleaned, loosening or
freeing debris from the surface. The end cap 160 extending between the agitator arm 140 and end of support 120 provides rigid support so that the agitator arm 140 does not deflect or bend when it is pressed hard against the surface being cleaned. After application of the agitator 141, the user rolls the cleaning roll 150 over the surface, where roll 150 rotates around the support 120. In the case of a tape roll for cleaning roll 150, the tape roll 150 has an adhesive surface facing outwardly, where the adhesive collects the loosened debris from the surface. The tape preferably includes many layers, so that when one layer is full of debris, it can be removed thus exposing a fresh layer with adhesive underneath.
It is to be understood that the present invention is not limited to the embodiment(s) described above and illustrated herein, but encompasses any and all variations falling within the scope of the appended claims. For example, references to the present invention herein are not intended to limit the scope of any claim or claim term, but instead merely make reference to one or more features that may be covered by one or more of the claims. The embodiments described above are disclosed with reference to roll 150 being an adhesive tape roll. However, any debris collecting roll having an outer surface that will collect debris when rolled over the surface to be cleaned can be used. For example, roll 150 need not be made of layers of tape, but rather could instead be a solid or composite substrate with a debris attracting outer surface (e.g. gel, rubber or other sticky or adhesive outer surface) for picking up debris without damaging or leaving a residue on the surface being cleaned. While handles having gripping portions parallel or perpendicular to the rolling direction of roll 120 are shown and described, handles 110 with other shapes could be used.
