Systems for providing electrical power in response to deposited coins
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a system for providing electrical power in response to deposited coins and more particularly pertains to allowing campers, truckers, motorists or the like to purchase the use of electrical outlets for the amounts of time for which they pay. 
     2. Description of the Prior Art 
     The use of electrical outlets is known in the prior art. More specifically, electrical outlets heretofore devised and utilized for the purpose of allowing an electrical hookup at a convenient site 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, the prior art discloses in U.S. Pat. No. 3,637,059 a coin-operated electric power supply station especially adapted for use in remote unsupervised locations. 
     U.S. Pat. No. 3,930,363 discloses a parking meter which electrically indicates &#34;remaining time&#34; and which electrically operates only in the presence of a vehicle and when there is &#34;paid-for&#34; time on the meter, for example, unused time by one departing motorist is cancelled. 
     U.S. Pat. No. 4,183,205 discloses an arrangement for resetting a coin operated parking meter by utilizing a sensor to monitor a parking space by determining when a vehicle leaves the parking space with parking time remaining. 
     U.S. Pat. No. 4,532,418 discloses a structure for and method of charging an electric vehicle at a parking location and facilitating billing for the charging energy utilized and the parking time. 
     U.S. Pat. No. 4,676,358 discloses a coin control system for determining whether proper coinage has been inserted to start a coin operated device. 
     Lastly, U.S. Pat. No. 5,184,707 also discloses a parking meter system. 
     In this respect, the system for providing electrical power in response to deposited coins 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 campers, truckers or the like to purchase the use of electrical outlets. 
     Therefore, it can be appreciated that there exists a continuing need for new and improved System for providing electrical power in response to deposited coins which can be used for allowing campers, truckers or the like to purchase the use of electrical outlets for the amounts of time they pay for. In this regard, the present invention substantially fulfills this need.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved system for providing electrical power in response to deposited coins embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     The present invention, the new and improved system for providing electrical power in response to deposited coins, is a system 10 comprised of a plurality of components. In its broadest context, such components, include a mounting post, an input head, a plurality of readouts, an output module and a microprocessor. These components are individually constructed and correlated one with respect to the other to most efficiently carry out the intended object. 
     More specifically, the central component of system is a mounting post 12. Such mounting post 12 is simply a support member secured at its lower end to the ground or other surface and with its upper end 16 adapted to support the other operational components of the system. 
     Located at the upper end 16 is the input head 20. The input head 20 is secured to the mounting post in a permanent relationship. Such input head 20 includes a plurality of slots 22, 24, 26 and 28. Such slots are adapted for the receipt of coins, as for example, slots for a nickel, dime and quarter. The fourth slot 28 is adapted to receive a token that might be utilized at the facility employing the system 10 of the present invention. The name of the coin to be deposited into the appropriate slot is written adjacent to such slots. The coins inserted into the slots are adapted to be used for determining the extent of the electrical energy to be provided when using the present system. 
     Next provided are a plurality of readouts 32, 34 and 36. Such readouts are printed on the input head 20. The function of the readouts is to indicate different types of information including the amount of coins deposited, the time of electrical usage remaining for the previously deposited coins and, an indication of the selected voltage. In association therewith, a switch 38 is provided for being pivoted to one position or the other to point to the 110 or 220 as an indication of the voltage to be selected. 
     Next provided is an output module 42. The output module 42 is located at the upper edge of the mounting post 12. It is located immediately beneath the input head 20. The output module 42 includes a pair of electrical receptacles 44 and 46. The first receptacle 44 is adapted for the receipt of a 110 volt plug with a grounding component in the conventional configuration. The second electrical receptacle 46 is adapted for the receipt of a 220 volt plug with a grounding component as well as horizontal and vertical legs. 
     The last and functionally central component of the system 10 is a microprocessor 50. The microprocessor 50 is adapted to receive input from the coins deposited and from the positioning of the switch. In response thereto, the readouts are illuminated for indicating the time of electrical usage remaining, the money deposited, and the voltage being supplied. In response to the inserted coins and the information on the readouts, the output device will supply electrical current for the user through the plug inserted in the receptacle corresponding to the selected voltage type. In this manner, during operation and use, the present system 10 will provide the desired time and voltage for current to be utilized for any purpose desired by the user. 
     A door 54 on the back of the input head 20 may be opened by a key 56 to allow collecting the money therefrom. 
     The present invention is a power timer that operates in the same fashion that a parking meter operates. The owner would have to run the appropriate electrical lines underground and up to and through the power timer. On the end of each meter, there would be a male/female socket that would connect to the electrical wire. The meter head would correspond with the amount of time along with the amount of money. For example, one dollar would allow the switch to be turned to the position that equals one hour. The relay would then start and continue until the switch &#34;clicked&#34; back to the starting position. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
