ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to battery chargers and more particularly pertains to a new portable self contained battery charger and radio for charging batteries for power tools.
2. Description of the Prior Art
The use of battery chargers is known in the prior art. More specifically, battery chargers 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 objective and requirements.
Known prior art includes U.S. Pat. Nos. 5,187,422; 2,591,438; 4,214,197; 5,396,162; 5,752,205; 4,691,383; and U.S. Pat. Des. No. 307,829.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new portable self contained battery charger and radio. The inventive device includes a portable housing having a top wall which is removable form the housing. A first plug is adapted for connecting to a home electrical power outlet. The first plug is a two prong plug operationally coupled to a first cord. A second plug for a vehicle power outlet is a cylinder having a first end and a second end. A wall connects the first and second ends. The first end has an electrical contact thereon and the wall of the second plug has an electrical contact thereon. The second end of the second plug is affixed to a second cord such that the first and second electrical contacts of the second plug are electrically coupled to the second cord. The first and second plugs provide power. A power cell for transforming current is mounted within the housing and has an outlet therein adapted to receive two pronged plugs. The power cell is operationally coupled to the power supply. A sound system for transforming audio and radio signals into sound is mounted in the housing and operationally coupled to the power cell. Two speakers are mounted in the front wall, and each of the speakers is operationally coupled to the sound system. A rechargeable battery for supplying power to the power cell is operationally coupled to the power cell. A recharger compartment for inserting battery rechargers is within the housing.
In these respects, the portable self contained battery charger and radio 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 charging batteries for power tools.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of battery chargers now present in the prior art, the present invention provides a new portable self contained battery charger and radio construction wherein the same can be utilized for charging batteries for power tools.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new portable self contained battery charger and radio apparatus and method which has many of the advantages of the battery chargers mentioned heretofore and many novel features that result in a new portable self contained battery charger and radio which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art battery chargers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a portable housing having a tip wall which is removable from the housing. A first plug is adapted for connecting to a home electrical power outlet. The first plug is a two prong plug operationally coupled to a first cord. A second plug for a vehicle power outlet is a cylinder having a first end and a second end. A wall connects the first and second ends. The first end has an electrical contact thereon and the wall of the second plug has an electrical contact thereon. The second end of the second plug is affixed to a second cord such that the first and second electrical contacts of the second plug are electrically coupled to the second cord. The first and second plugs provide power. A power cell for transforming current is mounted within the housing and has an outlet therein adapted to receive two pronged plugs. The power cell is operationally coupled to the power supply. A sound system for transforming audio and radio signals into sound is mounted in the housing and operationally coupled to the power cell. Two speakers are mounted in the front wall, and each of the speakers is operationally coupled to the sound system. A rechargeable battery for supplying power to the power cell is operationally coupled to the power cell. A recharger compartment for inserting battery rechargers is within the housing.
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 self contained battery charger and radio apparatus and method which has many of the advantages of the battery chargers mentioned heretofore and many novel features that result in a new portable self contained battery charger and radio which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art battery chargers, either alone or in any combination thereof.
It is another object of the present invention to provide a new portable self contained battery charger and radio which may be easily and efficiently manufactured and marketed.
It is another object of the present invention to provide a new portable self contained battery charger and radio which is of a durable and reliable construction.
An even further object of the present invention is to provide a new portable self contained battery charger and radio 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 self contained battery charger and radio economically available to the buying public.
Still yet another object of the present invention is to provide a new portable sel
