ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a floor mat with incorporated vacuum system and more particularly pertains to allowing dirt that normally accumulates to be instantly consumed.
The use of shoe cleaning devices is known in the prior art. More specifically, shoe cleaning devices heretofore devised and utilized for the purpose of cleaning shoes 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.
By way of example, U.S. Pat. No. 5,588,175 to Zahner discloses a device for removing debris from shoes using a vacuum assembly capable of being activated when the user steps on a resilient pad with a micro-switch incorporated. U.S. Pat. No. 5,991,967 to Williams discloses a device for cleaning the soles of shoes using an oscillating brush assembly and a vacuum. U.S. Pat. No. 4,425,677 to Cox discloses a shoe cleaning device using a liquid deodorant.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a floor mat with incorporated vacuum system for allowing dirt that normally accumulates to be instantly consumed.
In this respect, the floor mat with incorporated vacuum system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of allowing dirt that normally accumulates to be instantly consumed.
Therefore, it can be appreciated that there exists a continuing need for a new and improved floor mat with incorporated vacuum system which can be used for allowing dirt that normally accumulates to be instantly consumed. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In the view of the foregoing disadvantages inherent in the known types of shoe cleaning devices now present in the prior art, the present invention provides an improved floor mat with incorporated vacuum system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved floor mat with incorporated vacuum system which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a permeable mat portion having a generally rectangular configuration. The mat portion has an upper surface and a lower surface. The upper surface is defined by a plurality of upwardly extending bristles. A vacuum assembly is coupled with respect to the permeable mat portion. The vacuum assembly includes a rectangularly configured pipe circuit disposed below the lower surface of the mat portion. The pipe circuit has a main outlet pipe extending outwardly therefrom. The main outlet pipe has an open outer end disposed beyond the mat portion. The pipe circuit has a plurality of air intakes extending upwardly therefrom in a spaced relationship. The air intakes have open upper ends in contact with the lower surface of the mat portion. The vacuum assembly includes an intake housing positioned adjacently to the mat portion. The intake housing has a hollow interior defining a debris collection chamber. The intake housing receives the open outer end of the main outlet pipe therein. The intake housing has an air exhaust port. The vacuum assembly includes a labyrinth passageway extending from the open outer end of the main outlet pipe to the air exhaust port. The passageway has a debris filter therein above the debris collection chamber. The vacuum assembly includes a suction fan disposed within the intake housing above the debris filter. The vacuum assembly includes a pressure activation switch in communication with the suction fan. The pressure activation switch is disposed below the mat portion whereby pressure on the mat portion will cause the suction fan to be activated.
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, of course, 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.
It is therefore an object of the present invention to provide a new and improved floor mat with incorporated vacuum system which has all the advantages of the prior art shoe cleaning devices and none of the disadvantages.
It is another object of the present invention to provide a new and improved floor mat with incorporated vacuum system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved floor mat with incorporated vacuum system which is of durable and reliable construction.
An even further object of the present invention is to provide a new and improved floor mat with incorporated vacuum system 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 a floor mat with incorporated vacuum system economically available to the buying public.
Even still another object of the present invention is to provide a new and improved floor mat with incorporated vacuum system for allowing dirt that normally accumulates to be instantly consumed.
Lastly, it is an object of the present invention to provide a new and improved floor mat with incorporated vacuum system including a permeable mat portion having an upper surface and a lower surface. The upper surface is defined by a plurality of upwardly extending bristles. A vacuum assembly is coupled with respect to the permeable mat portion. The vacuum assembly includes a pipe circuit disposed below the lower surface of the mat portion. The pipe circuit has a main outlet pipe extending outwardly therefrom. The main outlet pipe has an open outer end disposed beyond the mat portion. The pipe circuit has a plurality of air intakes extending upwardly therefrom in a spaced relationship. The air intakes have open upper ends in contact with the lower surface of the mat portion. The vacuum assembly includes an intake housing positioned adjacently to the mat portion. The intake housing has a hollow interior defining a debris collection chamber. The intake housing receives the open outer end of the main outlet pipe therein. The vacuum assembly includes a suction fan disposed within the intake housing.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specif
