ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to paint application devices and more particularly pertains to a new portable spray booth for applying paint to plank-like members.
2. Description of the Prior Art
The use of paint application devices is known in the prior art. More specifically, paint application devices 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. Nos. 4,924,801; 3,904,431; 2,347,728; 5,597,414; 4,174,678; and 5,893,515.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new portable spray booth. The inventive device includes a housing having a top wall, a bottom wall, a front wall, a back wall and a pair of lateral side walls. The front and back walls each has an opening therein. The openings in the front and back walls are aligned and are positioned generally between the top and bottom walls. A delivery pipe is positioned in the housing and extends around an interior of the housing. A plurality of nozzles is fluidly coupled to the delivery pipe. An inlet pipe is fluidly coupled to the delivery pipe and extends through one of the lateral side walls. A pump is fluidly coupled to a container for pumping paint out of the container. The pump is in communication with the delivery pipe.
In these respects, the portable spray booth 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 applying paint to plank like members.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of paint application devices now present in the prior art, the present invention provides a new portable spray booth construction wherein the same can be utilized for applying paint to plank like members.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new portable spray booth apparatus and method which has many of the advantages of the paint application devices mentioned heretofore and many novel features that result in a new portable spray booth which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art paint application devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing having a top wall, a bottom wall, a front wall, a back wall and a pair of lateral side walls. The front and back walls each has an opening therein. The openings in the front and back walls are aligned and are positioned generally between the top and bottom walls. A delivery pipe is positioned in the housing and extends around an interior of the housing. A plurality of nozzles is fluidly coupled to the delivery pipe. An inlet pipe is fluidly coupled to the delivery pipe and extends through one of the lateral side walls. A pump is fluidly coupled to a container for pumping paint out of the container. The pump is in communication with the delivery pipe.
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 portable spray booth apparatus and method which has many of the advantages of the paint application devices mentioned heretofore and many novel features that result in a new portable spray booth which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art paint application devices, either alone or in any combination thereof.
It is another object of the present invention to provide a new portable spray booth which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new portable spray booth which is of a durable and reliable construction.
An even further object of the present invention is to provide a new portable spray booth 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 portable spray booth economically available to the buying public.
Still yet another object of the present invention is to provide a new portable spray booth 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.
Still another object of the present invention is to provide a new portable spray booth for applying paint to plank like members.
Yet another object of the present invention is to provide a new portable spray booth which includes a housing having a top wall, a bottom wall, a front wall, a back wall and a pair of lateral side walls. The front and back walls each has an opening therein. The openings in the front and back walls are aligned and are positioned generally between the top and bottom walls. A delivery pipe is positioned in the housing and extends around an interior of the housing. A plurality of nozzles is fluidly coupled to the delivery pipe. An inlet pipe is fluidly coupled to the delivery pipe and extends through one of the lateral side walls. A pump is fluidly coupled to a container for pumping paint out of the container. The pump is in communication with the delivery pipe.
Still yet another object of the present invention is to provide a new portable spray booth that may be taken within a dwelling for applying paint to multiple planks in an efficient manner.
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 specific object
