Description

CLEANING IMPLEMENT

BACKGROUND OF THE INVENTION

Difficulties controlling dust have been well documented in the art. Indeed, most have come across collections of dust at home, work, and the like. However, controlling the population of dust particles has been a long recognized difficulty.

Devices for controlling dust include items as simple as wiping with a rag or towel. However, using a rag or towel poses a significant burden on the user. For example, the reach of the rag or towel is substantially the same as the span of the user's arm and/or hands. Also, rags or towels pose cleanliness issues in that the dust particles trapped by the rag or towel easily come into contact with the user's person, thus spreading the dust particles.

Other cleaning implements have also been contemplated. One standing problem with these implements involves the amount of surface they are capable of cleaning. Specifically, the configuration of these cleaning implements is such that they are capable of cleaning one flat surface at a time, resulting in cleaning inefficiencies. Because these cleaning implements are capable of cleaning one surface at a time, at lease two passes of the cleaning implement must be utilized in order to sufficiently remove dust from the surfaces to be cleaned.

While attempts to improve the cleaning characteristics of dusters or cleaning implements have been made, there has to date been no cleaning implement that substantially eliminates its problems and inefficiencies.

It is, therefore, highly desirable to create a cleaning implement that maximizes a user's effort while minimizing the spreading of dust particles. Further, it is highly desirable to maximize the functionality and versatility of a cleaning implement. This invention accomplishes those goals.

SUMMARY OF THE INVENTION

A first aspect of this invention relates to a cleaning implement comprising a base, at least two prongs functionally connected to the base, wherein each prong is capable of receiving at least one cleaning material having a cleaning portion, wherein said at least two prongs substantially parallel to a longitudinal axis, and wherein said cleaning implement when rotated 360° about the longitudinal axis is capable of contacting said cleaning portion with a surface during at least about 185°. A second aspect of this invention relates to a cleaning implement comprising a base, a first prong and a second prong functionally connected to the base wherein the first prong and the second prong are capable of receiving at least one cleaning material, a pivot longitudinally interposed between the first prong and the second prong wherein at least one of the first prong or the second prong is capable of at least partially rotating about the pivot, and a lock functionally connected to at least one of the first prong or the second prong capable of at least temporarily fixing at least one of the first prong or the second prong about the pivot.

In such an embodiment, the device of the present invention is capable of at least temporarily fixing at least one prong about the pivot in at least two or more positions, in another embodiment two positions. As a non-limiting example, a first lock of the present invention is utilized to hold the prongs at least about 165°, in another embodiment at least about 170°, in another embodiment at least about 175°, in another embodiment substantially planar when measured about the pivot as the center or vertex of the angle. A second lock of the present invention is utilized to hold the prongs at least hold the prongs less than about 20°, in another embodiment less than about 15°, in another embodiment less than about 10°, in another embodiment less than about 5°, in another embodiment substantially parallel when measured about the pivot as the center or vertex of the angle.

It is contemplated that where there exists more than one lock, the prongs may be at least temporarily fixed in multiple positions. These positions, as formed by the angle from the first prong and second prong with the pivot as the vertex include substantially planar, substantially parallel, substantially perpendicular, acute, obtuse, less than about 90°, greater than about 90°, less than 45°, greater than 45°, less than about 10°, less than about 5°, from about 170° to about 190°, from about 175° to about 185°.
