ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to scrubbers and more particularly pertains to a new grout scrubber for providing interchangeable brush heads to facilitate use of a brush size corresponding to the surface being scrubbed.
2. Description of the Prior Art
The use of hand held scrubbers is known in the prior art. More specifically, scrubbers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 5,412,829; U.S. Pat. No. 5,224,234; U.S. Pat. No. 5,809,604; U.S. Pat. No. 5,319,824; U.S. Pat. No. 4,064,588; and U.S. Pat. No. Des. 378,959.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new grout scrubber. The inventive device includes a scrubber portion and a handle assembly. The scrubber portion is slidably couplable to the scrubber portion. The scrubber portion includes a slot having angled sides and a nipple for engaging the handle assembly. In an embodiment, a protrusion is positioned on the handle assembly to engage the nipple on the scrubber portion. The handle assembly provides a grip at a distal end of an elongated handle. In an embodiment, the elongated handle is separable into two sections threadingly engageable to each other. Alternately, the handle assembly provides an angled shortened handle having an offset grip for scrubbing surfaces at an elevated level within reach of an upright user. The interchangeable scrubber heads provide various thicknesses and materials to provide flexibility and facilitate selection of a desired scrubber type and style most suitable for cleaning the desired surface.
In these respects, the grout scrubber according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of providing interchangeable brush heads to facilitate use of a brush size corresponding to the surface being scrubbed.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of scrubbers now present in the prior art, the present invention provides a new grout scrubber construction wherein the same can be utilized for providing interchangeable brush heads to facilitate use of a brush size corresponding to the surface being scrubbed.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new grout scrubber apparatus and method which has many of the advantages of the scrubbers mentioned heretofore and many novel features that result in a new grout scrubber which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art scrubbers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a scrubber portion and a handle assembly. The scrubber portion is slidably couplable to the scrubber portion. The scrubber portion includes a slot having angled sides and a nipple for engaging the handle assembly. In an embodiment, a protrusion is positioned on the handle assembly to engage the nipple on the scrubber portion. The handle assembly provides a grip at a distal end of an elongated handle. In an embodiment, the elongated handle is separable into two sections threadingly engageable to each other. Alternately, the handle assembly provides an angled shortened handle having an offset grip for scrubbing surfaces at an elevated level within reach of an upright user. The interchangeable scrubber heads provide various thicknesses and materials to provide flexibility and facilitate selection of a desired scrubber type and style most suitable for cleaning the desired surface.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new grout scrubber apparatus and method which has many of the advantages of the scrubbers mentioned heretofore and many novel features that result in a new grout scrubber which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art scrubbers, either alone or in any combination thereof.
It is another object of the present invention to provide a new grout scrubber that may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new grout scrubber that is of a durable and reliable construction.
An even further object of the present invention is to provide a new grout scrubber which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such grout scrubber economically available to the buying public.
Still yet another object of the present invention is to provide a new grout scrubber which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Yet another object of the present invention is to provide a new grout scrubber that includes a scrubber portion and a handle assembly, the scrubber portion being slidably couplable to the scrubber portion.
Yet another object of the invention is to provide a scrubber portion that includes a slot having angled sides and a nipple for engaging a protrusion on the handle assembly. The handle assembly provides a grip at a distal end of an elongated handle. The elongated handle is separable into two sections threadingly engageable to each other. Alternately, the handle assembly provides an angled shortened handle having an offset grip for scrubbing surfaces at an elevated level within reach of an upright user.
Still yet another object of the present invention is to provide interchangeable scrubber heads of various thicknesses and materials to provide
