ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pitcher pump water dispensing system and more particularly pertains to efficiently collecting and storing water from a source until it is ready to be dispensed.
2. Description of the Prior Art
The use of water regulation devices is known in the prior art. More specifically, water regulation devices previously devised and utilized for the purpose of controlling water flow are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 5,836,346 to Nichols-Roy discloses an pilot operated diaphragm fill valve. U.S. Pat. No. 5,715,859 to Nichols-Roy discloses a adjustable fill valve assembly. U.S. Pat. No. 5,975,125 to Nichols-Roy discloses a combined filter and noise suppressor for fill valve. U.S. Pat. No. 2,434,771 to mueller et al discloses a liquid dispenser. Lastly, U.S. Pat. No. 4,413,778 to Middlemiss discloses an antique lawn pump mobile.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a pitcher pump water dispensing system that allows for efficiently collecting and storing water from a source until it is ready to be dispensed.
In this respect, the pitcher pump water dispensing 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 efficiently collecting and storing water from a source until it is ready to be dispensed.
Therefore, it can be appreciated that there exists a continuing need for a new and improved pitcher pump water dispensing system which can be used for efficiently collecting and storing water from a source until it is ready to be dispensed. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of water regulation devices now present in the prior art, the present invention provides an improved pitcher pump water dispensing 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 pitcher pump water dispensing system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a pitcher pump water dispensing system first includes a pitcher pump that has a generally cylindrical central portion. This central portion has a top region and a bottom region with an opening on the bottom region with female threads. The pump further has a cone shaped open top portion adjacent to the top region of the central portion. The top portion has a laterally disposed dispensing spout. The pump also includes a base with a diameter greater than that the of central portion. The base has a lip with a plurality of bores there through. Next the pump includes a sloping intermediate section between the bottom region of the central portion and the base. The intermediate section has a plurality of openings there through. The pump includes a centrally pivoted pumping handle with a drive rod coupled thereto and a one-way seal. The handle is coupled to a pivot plate. The pivot plate is coupled to the top portion on a side opposite the dispensing spout. When in operation the seal provides a vacuum upon reciprocating of the handle. This draws water up the central portion and out of the spout. The system next includes a reservoir. The reservoir has a cylindrical base section of a uniform diameter with a planar bottom. The reservoir also includes a cylindrical top section with a curved intermediate section. The top section has a curved lip portion. A receiving pipe with an upper end with male threads is coupled to the bottom region of the pump. The receiving pipe has a lower end extending adjacent to the bottom of the reservoir. The reservoir also has handles extending outward from the curved intermediate section. The system further includes a connector. The connector has a solid cylindrical top plate of a diameter slightly greater than that of lip section of the reservoir. The top plate has a central opening and a plurality of bores around the perimeter to receive a plurality of nuts and bolts to couple the connecting means to the base of the pumping means. The connecting means further has a ledge extending down from the top plate. Next, a control assembly has an intake pipe with a top end and bottom end. The bottom end has male threads and the top end has a valve mechanism coupled thereto. The control assembly includes a floating regulator attached adjacent to the intake pipe at a set height to indicate maximum allowed water level in the reservoir. The regulator means responding to the water level in the reservoir and mechanically activates and deactivates the valve by means of lever linkage arms. The control assembly is adjustably held stationary by a upper and lower clamps. The upper clamp is coupled to the lower end of receiving pipe of the reservoir and clasps the bottom end of the intake pipe. The lower clamp is coupled to the top end of the intake pipe and has a long rod parallel to the receiving pipe. The lower clamp also has a guide post associated with it which is coupled to the receiving pipe through which the rod slides. The control assembly allows water to flow into the reservoir when the water level is low as compared to the position of the clamps and stops the flow of water when the desired water level is reached. Furthermore, the system includes an inlet hose. The inlet hose is coupled to the bottom end of the intake pipe of the control assembly. From the intake pipe the inlet hose extends through one of the openings of the intermediate section of the base of the pumping means to a propelled water source. Finally, the system includes a support base. The support base has a round planar platform having a top face and bottom face. A pair of wheels are coupled along a single side and a resting stub is coupled along an opposite side of the bottom face of the support base. The support base allows the system to be easily moved and as well as rest in a balance fashion.
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 attached.
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 descriptions 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 pitcher pump water dispensing system which has all of the advantages of the prior art water regulation devices and none o
