     TECHNICAL FIELD 
       [0003]    Generally, the invention relates to an electrical distribution device comprising a plurality of receptacles for providing both alternating and direct current (AC/DC). Specifically, the invention is a vending machine that distributes metered electricity for use in powering small hand-held devices and/or charging electronic devices. Thus, the invention assists people that need a place to recharge their electrical devices. It should be noted that in the United States, electricity is traded or sold on the electrical grid in amounts of kilowatt/hours. In the present invention, metered electricity is to be sold in typical smaller increments of watts/minutes. 
       BACKGROUND OF THE INVENTION 
       [0004]    Most households in the United States are connected to the electrical grid and receive a supply of electricity therefrom. However, with the continued reduction of coal usage in the production of electricity, the cost of electricity is rapidly increasing. Such cost increases tend to push the budget of fixed-income families, which may result in these families being driven from the electricity marketplace because they are unable to pay a monthly electric bill. As most depend on a cellular telephone or other electrical device to remain in contact with their loved ones, they may need to borrow electricity from others. This tends to inconvenience others and is not a long-term solution to living without reliable electricity. 
         [0005]    In third world countries, there may be no electrical grid. Or, the electrical grid may be unreliable and experience frequent failures. Moreover, many foreign countries have grids which only periodically provide electricity. That is, the electrical grids in these countries may only operate for a few hours each day and do not provide electricity constantly. It is an aim of the instant invention to provide an electrical distribution center for those who are in need of electricity but not connected to a reliable electrical grid. 
         [0006]    There are a variety of devices that have be utilized in distributing electricity. By way of example, the following devices exemplify such devices. U.S. Pat.

In this instance, 120 VAC is routed onto a terminal bus  49  which includes at least four sets of terminals. The ground, neutral and hot wires are connected onto one side of a respective terminal. The ground is coupled to the metal casing of the machine and to the respective grounds on each receptacle  39  as well as a ground rod or the like. Likewise, the neutral wire is connected to the neutral on the GFCI protected receptacles  39 . The hot wire is routed into a relay  47  which is energized when a coin is deposited into the machine and counted by the coin-counter  48  to provide electricity to the receptacles  39 . A timer  46  and associated cherry micro switch  44  is provided for controlling the amount of time that the receptacles are energized. 
         [0046]    It should be noted that in this instance, the receptacles include a circuit which provides 5 VDC to the USB portion of the receptacles. Such circuits may be known ones such as a Wheatstone Bridge, chopper circuit, voltage divider and associated diodes, capacitors or transformers or the like for stepping down and converting the 120 VAC to 5 VDC. These circuits could be provided external to the receptacles and the power supplying the USB may be coupled to separate inputs than the 120 VAC hot wire and may be turned on and controlled by the timer. However, in the preferred embodiment, the receptacles include the converting and stepping down circuits. 
         [0047]    The casing may comprise a partition for mounting various parts mentioned above. The machine may be mounted atop a metal tube  150  as shown in  FIG. 1F . In this instance, a pair of plates  151  is fastened on the top and the bottom of the tube. The top plate is fastened to the bottom of the casing and the bottom plate is fastened to a solid surface such as a base of concrete. 
         [0048]      FIG. 2A  shows a second embodiment of the machine. In this instance, the machine includes a human interface comprising a keypad  60  with numbers  1  through  9  and having an up button  61  and down button  62  for toggling between options shown on the display  63 . A coin slot  8 , coin return button  7 , and a coin return opening  6  are provided as in the first embodiment. A bill acceptor  64  and a card reader  65  is also provided for accepting both paper money and either a credit or debit card or the like. The bill acceptor  64  accepts money currency and credits the amount of electricity provided through the GFCI receptacles for a prepaid period of time. A card reader  65  allows a user to charge or debit the cost of the electricity to a credit card or debit card respectively. In this instance, the GFCI receptacles  39  are arranged on the side and may be accessed in similar fashion as mentioned above with respect to the first embodiment, as more clearly shown in  FIG. 2B . Likewise, the GFCI receptacles  39  are selectively powered through a relay  47 . 
         [0049]      FIG. 2B  shows one embodiment of the invention fastened to a pole  150 . The pole  150  includes a bend  151  and an upper portion to which a solar panel  155  is fastened. The bottom of the pole extends into a flared region  156  which fastens to a metal box  157  which houses batteries  175  that store electricity for use when the sun is not shining. A hinged door  158  is provided on the side of the box to provide access to the batteries  175 . The box  157  is solidly fastened to the ground. In this instance, a receptacle  39  is arranged within the security locker  28 . As in the first embodiment, each security locker  28  includes a door  27  through which access to the security locker  28  may be controlled through a microprocessor  95 . Upon deposit of money, a random code is generated by the microprocessor  95  and assigned to an electronic lock register which corresponds to the control of the electronic lock. In this manner, the electronic lock arranged on the security locker door is disengaged when the randomly generated code is entered. That is, when the code that is currently stored in the electronic lock register of the microprocessor is entered into the machine via the keypad, the associated lock with a particular security locker is disengaged to unlock that security locker door. The user then opens the door, connects their device to the receptacle  39 , and closes the door which is then locked until such time as the particular code is re-entered into the microprocessor via the keypad and display. Once the code is used to open the security locker twice, the code is then changed via a random number generator in the microprocessor and used by the next user in a similar fashion to open the security locker twice.  FIG. 2C  is a perspective front view of the second embodiment. 
         [0050]      FIG. 3  shows a third embodiment of the machine. In this instance, the keypad includes an enter button and a cancel button along with buttons representative of numbers  1 - 9 . The GFCI receptacles and their associated spring-loaded covers are provided above the keypad  60  along with a display  63  and the respective currency accepting devices  8 ,  64 ,  65 . 
         [0051]      FIG. 4  is a representative schematic showing a solar panel  155  coupled to a charge controller  174  and a pair of batteries  175 . The solar panel  155  charges the batteries during the daylight hours while the sun is shining after which the energy stored in the batteries are utilized when at night or during overcast days. It should noted that the solar panel may be substituted for another power source such as the electrical grid. Energy from the batteries is converted from DC to AC in inverter  173 . Electricity from the inverter  173  is routed to a terminal bar or bus  172 . A neutral is connected to a first set of terminals. A ground is coupled to another set of terminals. A constant hot is routed to a third set of terminals. The last set of terminals is a controlled electricity which is only energized when relay  47  is on. This controlled electricity is timed in accorded with the amount of currency that is deposited into the machine. For purposes of understanding, the coin counter  48  is only shown in this schematic. However, it is to be recognized that the bill acceptor  64  and card reader  65  are also connected to the microprocessor  95  for causing the GFCI receptacles to be energized in accord with an amount of currency deposited into, charged to, or debited to the microprocessor  95 . The microprocessor  95  is connected to the display  63  for providing commands, passwords, or other data necessary to operate the machine  1 .
