Full Description:
FIELD OF THE INVENTION 
       [0001]    This application claims priority to U.S. Provisional Patent Application Ser. No. 62/050,645 filed on Sep. 15, 2014, which is included herein in its entirety by this reference thereto. 
     
    
       [0002]    This invention relates generally to a solar powered charging station configured for recharging cell phones, tablets, laptops and other electronic devices. More particularly, it pertains to an environmentally friendly device and method for the provision of a charging station for electronic devices providing comfortable shaded seating from an overhead shade structure adapted with an angle to increase shade and maximize the output of rooftop solar energized panels producing electrical current to power the device. 
       BACKGROUND 
       [0003]    In recent years, the popularity of portable electronic devices employed for computing, communications, presentations, mapping and navigation and for other functions has expanded exponentially. In recent years, with the expansion of wireless network capabilities of both public and private networks, smartphones, pad computers, and a plethora of other devices populate the electronics market. All of which have rechargeable batteries which must frequently be charged. 
         [0004]    This need to maintain an operable charge on such portable electronic devices will only increase with the ever expanding number of wireless devices and available wireless networks and mobile hotspots to service such devices. By nature, such devices employ electrical power for the broadcast and receipt of data during network connections. Concurrently, with the battery drain caused by RF wireless communications, the display screen and the electronic computing components of the devices all use electrical power to produce the displayed indicia on the engaged display screen and to process the data using software on the computer component of such devices. This results in a continuous plurality of sources of power drain from the batteries on portable wireless devices as well as portable devices which may be hard-wired to a network connection since the onboard network card employs electric power to transmit and receive data over the network. 
         [0005]    Other larger devices use onboard electrical power stored in batteries. Such include for example golf carts, wheel chairs, powered coolers for food and other contents, and a host of portable devices which use electricity to function and draw such from batteries. Just as with smaller devices, these large devices using power must be recharged to continue to function. 
         [0006]    Conventionally, users of portable electronic devices, both small and large, must plug electric chargers into their electronic portable devices. These charging devices generally are connected to the local electric grid and after a duration of connection will provide a recharge of electric power to onboard batteries of small and large portable devices. Alternatively, many users have vehicle-engageable chargers which may be employed to charge their portable device using a connection to the vehicle in which they may be riding such as a car, truck, airplane, or train or the like, which has an electric generating capability. 
         [0007]    However, many public places where users of portable electronic devices may traverse, such as airports, beaches, recreation areas and the like, have severely limited connections to the power grid for recharging portable electronic devices. This lack of grid power results in users of small and larger portable battery-powered electronic devices being unable to recharge their power supplies when such is invariably required. 
         [0008]    Additionally, many airlines and train lines do not provide connections for device chargers during travel, or offer connections which are not compatible with the charger employed by many users. Thus, the electronic portable devices of users can frequently discharge onboard batteries to the point the portable device becomes inoperable. 
         [0009]    The problem for electronic device users having trouble charging their battery-powered electronic devices is not limited to traveling. Average users frequently forget to charge their device at home or the office, and then find themselves located with their electronic phone or pad computer or other battery-powered device is in danger of losing function when they are visiting a shopping center, mall, campus, beach, outdoor venue such as a zoo or concert, or other venues lacking a connection to the local grid or another power supply. 
         [0010]    While there are charging stations inside many such venues such as airports and campuses, such charging stations are at best inconvenient. This is because they require the user to stand proximate to their slowly charging device, or leave it to charge and risk the potential their device might not be at the charging station when they return. Some such charging stations will provide an exchange of a portable charging component engageable with the user&#39;s device. However, most such charging stations generally charge very high rates to use the provided power connections, and use grid-power produced by fossil fuels and therefor not environmentally friendly, and not positionable in locations where such grid power is not easily connected. 
         [0011]    As such, there is an unmet need for a device and method which will provide for the charging of electronic devices for users who may be situated at airports and train stations, outdoor concert venues, shopping centers, campuses, hotels, spas, parks and other public places not proximate to an electrical grid power connection. Such a device should be adapted to both capture and employ electrical power from a regenerative source which is environmentally friendly. Further, such a device and method should not only provide the users with electrical power, but also provide users a comfortable and preferably shaded and climate controlled area to sit while their device is being re-energized, which also takes advantage of regenerative power sources. Finally, such a device should be configured with electrical storage capacity and sufficient solar electrical generation to allow the charging station device to be located at any outdoor venue without the need for a connection to a power grid, thereby significantly increasing the number of venues where the charging station device may be placed. 
         [0012]    With respect to the above, before explaining at least one preferred embodiment of the device and method for recharging portable electronic devices in detail or in general, it is to be understood that the invention is not limited in its application to the details of employment and to the arrangement of the components or the steps set forth in the following description or illustrated in the drawings. The various apparatus and methods of the herein disclosed invention for capturing solar power and providing both charging and cool shaded areas for sitting is capable of other embodiments, and of being practiced and carried out in various ways, all of which will be obvious to those skilled in the art once the information herein is reviewed. 
         [0013]    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 other charging devices and methods. It is important, therefore, that the embodiments, objects and claims herein, be regarded as including such equivalent construction and methodology insofar as they do not depart from the spirit and scope of the present invention. 
       SUMMARY OF THE INVENTION 
       [0014]    The charging station device and method herein solve the shortcomings of the prior art, through the provision of an easily loadable combination including a charging station with user seating which is configured for positioning anywhere an adequate sunlight supply is available to generate electrical power. Thus, the device herein may be situated outside in malls or shopping centers, outdoor concert and other arenas, outdoor areas adjacent airports and train stations, beaches, national parks, and virtually anywhere the sun rises for a sufficient time to charge the onboard batteries using the roof-positioned solar cells. 
         [0015]    The roof-mounted photovoltaic solar panel or a solar array of such solar panels, includes sufficient solar cells to generate electric power when contacted with the anticipated sunlight in the geographic area which the device is to be located, to charge one or a plurality of onboard eclectic storage batteries operatively engaged to the solar array. The slanted roof, supported by opposing sidewalls, doubles as a shade structure and rain shield for users of the device who may be seated on an underlying bench or seat which is situated to cover a lower housing atop a battery compartment therein. Operative wiring from the solar array to the underlying eclectic storage batteries within the battery compartment is routed through passages within the roof and the supporting sidewalls and thereby communicate to operative engagement with the batteries located in the battery compartment. 
         [0016]    The opposing sidewalls engaged to the base on opposite sides of the seating bench are unequal in length to thereby impart a determined slant to the roof and engaged solar array, when operatively situated over the underlying bench. This angle or slant of the roof may be changed to maximize the communication of sunlight to the solar array when the device is operatively postponed on the ground or support surface at a venue. This determined angle of the roof relative to a level roof may change depending on the latitude in which the device is located for operation. A greater incline or slant may be imparted to the roof of devices located at latitudes closer to the North or South poles to better provide for sunlight contact with the solar panel and such may be accommodated by changing the length of extension above the bench of one or both sidewalls which may be configured for independent replacement to accommodate such a change in angular disposition of the roof. 
         [0017]    Wired in operative communication with the batteries are a plurality of charging ports, and/or power sockets such as AC power sockets, and/or inductive charging components, which are operatively engaged with power plates positioned on the sidewalls. Appropriate electric transformers and power invertors if needed and other components well known in the art to convert DC solar panel voltage to the desired AC or DC power and voltage, will be situated between the batteries which are charged by the solar panel, as well as in-between the storage batteries and one or a plurality of user-engageable connectors for charging wires located in the power plates. 
         [0018]    One or a plurality of power plates will be populated with such electrical connectors which may vary in mechanical configuration for allowing for engagement for any of multiple power cords which users may employ to communicate electric power from the charging station device, to charge the battery on their respective electronic device, or to power for instance an AC powered device such as a drill or charging of electric vehicles. 
         [0019]    Inductive charging connection areas may also be provided for wireless charging. Such will allow users having differing power cord connectors to operatively connect their electronic device to the system herein for charging or to power the device in real time. The connectors are of course adapted for replacement to allow for engagement of new connecters as standards change over time. 
         [0020]    Additionally, provided to facilitate easy transport and location is a recess or passage formed at a bottom edge of opposing sidewalls of the lower housing section of the charging station device. A passage communicating between and through the recesses in the bottom edges of the opposing sidewalls will allow for the operative communication of forks from a pallet jack or forklift or the like to elevate the charging station device for easy rolling transport to a desired position at a venue or geographic location. 
         [0021]    Further provided in the favored mode of the device, is an LED illuminated overhead panel to provide lighting to the area of the charging station under the roof. Such will run on electrical power generated by the solar panels or array and will use minimal electrical power to provide maximum illumination of the seating area under the roof when required. 
         [0022]    Employing the onboard electric power generated by the solar array and stored in the onboard batteries located within the lower housing, and employing electric components operatively engaged for the interfacing electric power to the component or purpose, the device may also be configured for: 
         [0023]    security camera monitoring of surrounding areas employing WiFi or other wireless communication to communicate captured images; 
         [0024]    providing cooling fans and/or water misting for users positioned under the roof; 
         [0025]    providing a potable water supply to users through the employment of solar powered water condensing; 
         [0026]    providing an emergency medical station where patients may be provided care remotely; 
         [0027]    providing a safe haven wherein operative RF monitoring components and software running on a computing device powered by the power from the device would ascertain any emergency call made within 100 feet and emit a light and sound beacon to dissuade attackers and or alert first responders to the area of the situation; 
         [0028]    providing cold water and other products using solar powered refrigeration; 
         [0029]    using onboard wireless communications equipment powered by the charging station device, providing weather information from an onboard display and speakers or interactive sports odds/betting; 
         [0030]    using an onboard display powered by the batteries of the charging station device to operatively engaged wireless media electronic components to generate a feed to the display and/or sound, provide a news feed, sports scores, interactive news, a stock ticker, a local events calendar, a photo booth, a video calling station, a Lo-jack/find my phone interface, an emergency telephone call station or beacon, or other media which may be generated by the onboard electronic equipment operatively powered by the power generated by the device. 
         [0031]    Additionally, employing the onboard power generated by the batteries or solar panels of the charging station device, and operative electronic components also thereby powered, the charging station device may also function as an emergency broadcast system warning device to warn people proximate thereto of an immediate emergency, and to emit a visual and/or audio warning and safety instructions in such an event, for example an approaching tsunami at a beach location. 
         [0032]    Finally, the device and system may function using the onboard power as an Amber/Silver Alert notification system to operative electronic phones and computers of people proximate to the charging station device in the event of an Amber Alert or Silver Alert. In such an event, operative well known electronic components operatively engaged with the charging station device would emit a visual and audio signal, as well as provide images on the onboard display of those missing, their last known whereabouts and any vehicle information pertinent to the bulletin. 
         [0033]    As can be discerned, the charging station device herein, through the provision of onboard electrical power generation and storage capacity, can provide any or all of the above functions in a single unit, all of which are enabled wirelessly thereby allowing the positioning of the device virtually anywhere sufficient sunlight is available to provide the electrical power from the onboard solar array, to charge onboard electric storage such as a battery or batteries, to power the electronic components needed for the included functions. 
         [0034]    It is an object of this invention to provide an electric power generation charging station device in combination with a roofed seating area for users to occupy during use. 
         [0035]    Another object of the invention is to provide such a power generation device and user occupied roofed housing which includes power connections and wireless communications to operate a plurality of electronic components and video displays and audio producing components to enable the device for multi functions without the need for a connection to the power grid or a hard wired connection to a network. 
         [0036]    The foregoing has outlined some of the more pertinent objects of the invention provided by the device and system herein. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed device and system in a different manner or by modifying the invention within the scope of the disclosure. 
         [0037]    Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0048]    Referring now to  FIGS. 1-10  herein, wherein similar components are identified by the same numerals, there can be seen in one favored view of the charging station device  10  showing an assembled view showing the structural and ornamental aspects of the unique configuration of the assembled device  10 . The device  10  has a housing  11  formed of an upper section  13  in a removable engagement to a lower section  15  which provides for ease of configuration the tilt of the roof  14  to adjust an angle of the solar panel  12  thereon. The device  10  is lightweight and easily loadable thereby providing a combination charging station and user shelter and seating apparatus which is adapted for positioning anywhere an adequate sunlight supply is available for the solar panel  12 . 
         [0049]    Shown in  FIGS. 1-3  are a roof-mounted photovoltaic solar panel  12  or solar array, which includes sufficient solar cells to generate electric power for the intended use of the device  10  taking into consideration the geographic area which the device  10  is to be located. The roof  14 , providing the mount for the solar panel  12 , is supported by opposing support walls  16  and  18 , and so supported, forms a shade structure within the user cavity between the roof  14  and the bench  20  as well as a rain shield for users who may be seated on the underlying bench  20  positioned on top of a lower section  15  of the housing  11 . 
         [0050]    Shown in  FIG. 3 , the lower section  11  of the housing  11  has an interior cavity  24  underneath the bench  20  which may be padded with a cushion  19 . Supports  21  support users seated on the upper wall of the cavity  24  defining the bench  20  and which defines a top area of the interior cavity  24  which is sized for the operative positioning of a plurality of one or a plurality of batteries  26  therein. 
         [0051]    Operative wiring (not shown but well known) communicates through both the lower section  15  and upper section  13  of the housing  11  such as running through supports  41  in the support wall  18  along a race therein, from the solar array or solar panel  12 . This allows communication of electric power to the underlying batteries  26  within the interior cavity  24 . The wiring for both the batteries  26 , and any electronic interfaces, wireless communications, inventors, transformers, and to and from video displays and charging connections, and the like, is routed through passages within the roof  14  and the supporting sidewalls  16  and  18  and the interior cavity  24  and is well known in the art and need not complicate the drawings by depiction thereof. 
         [0052]    As shown in  FIGS. 1-3  the opposing support walls  16  and  18  are engaged to the lower section  15  of the housing  11  on opposite sides of the formed bench  20  using removable mating connections between both components such as plates  39  operatively positioned on both the support walls  16  and  18  and opposite ends of the lower section  13  of the housing  11 . 
         [0053]    The sidewalls  16  and  18  as shown, are purposely formed unequal in length to thereby impart a determined slant to the roof  14  providing the mount for the solar array  12 . This angle of the roof  14  can be changed, by changing the respective length of one or both sidewalls  16  and  18 . The angle of the roof  14  being changeable is particularly preferred so as to maximize the communication of sunlight to the solar panel  12  of the device  10 , depending on the latitude in which the device  10  is positioned for operation. 
         [0054]    Wired in operative communication with the batteries  26  are a one or preferably a plurality of charging ports engaged with the housing  11  with plates or power plates  27 . The plates  27  are configured to engage with the housing  11  with one surface exposed which has an electric connector therein such as such as AC or DC power sockets, and/or inductive charging components, which are operatively engaged with power plates  27  positioned on the sidewalls  16  and  18  or roof  12  interior. Such connectors might also include USB cord connectors, plug receptacles for AC power cords, or any other connector configured to engage and existing or future connector used for charging a portable electrically powered device. The plurality of power plates  27  can be populated with a plurality of differing electrical connectors adapted to engage a plurality of different power cords which users may employ to communicate electric power from the device  10 , to their respective electrical device for charging, or to power for instance an AC powered device. 
         [0055]    Additionally preferred in the device  10 , as shown in FIGS.  1 - 3  for example, to facilitate easy transport, is a recess  30  formed in opposing sidewalls of the lower section  15  of the housing  11 . As noted the opposing recesses  30  form a passage therethrough and therebetween, underneath the lower section  15  configured for engagement of a lifting component such as forks from a pallet jack or forklift or similar lifting component which may be employed to elevate the device  10  for easy rolling transport to the desired position. 
         [0056]    As shown in  FIG. 2 , the device  10  may also include an engagement of the solar panel  12  to the roof  14  on a rotatable member or axis  21 . The axis  21  may be engaged to an electrically operated or mechanical rotating component  23  such as an electric motor. With the included axis  21  engagement of the solar panel  12 , it may be tilted around the axis  21  to optimize the angle of contact of sunlight with the solar panel  12 , in addition to adjusting the tilt of the roof  14 . By including the axis  21  and rotating component  23  the solar panel  12  will thus be angularly adjustable in two different planes. Additionally, shown in  FIG. 2  are an optional video display  31  and the inclusions of means for electronic payment by a user such as a credit card reader  33  or other means for digitally authorizing payment. 
         [0057]    Shown in  FIG. 3 , and additionally preferred for inclusion in the favored mode of the device  10  herein, is an LED illuminated panel  32 . The illuminated panel  32  is preferred to provide illumination to the area under the roof  12  which is a low power draw from generated power from the solar panel  12 . A diffuser  33  is situated to provide even directed light from the LED panel  32 . 
         [0058]    As noted, using the electric power generated by the solar panel  12  and stored in a plurality of batteries  26  within the lower section  15  of the housing  11 , and employing electric components operatively engaged for the purpose, the device may also be configured with a digital video camera for security camera monitoring of surrounding areas. The camera may employ hard wiring or wireless communication to send captured images to a remote location. A fan may be engaged to the roof  14  of support walls  16  and  18 , to provide a cooling breeze to users positioned under the roof  14 . 
         [0059]    In other modes a water filtering component might be powered and engaged and provide a potable water supply to users or such might be supplied using solar powered water condensing. Using RF communication equipment  41  such as transceivers the device  10  may be configured for RF monitoring and software running on a computing device  43  having electronic memory and electronic computing processors powered by the power from the device  10  can operate as a cellular antenna and re broadcaster and also operate to monitor RF traffic and ascertain any emergency call made within  100  feet of the device  10 . Thereafter, it may be configured to emit a discernable alarm, such as a light and sound beacon to dissuade attackers and or alert first responders to the area of the situation. 
         [0060]    Additionally, the computing device  43  and the onboard wireless RF communications equipment  41  powered by the device  10  and the video display  31  the device  10  can be enabled to provide weather information from the onboard display  41  and speakers (not shown). Or the device  10  can be configured as an informational stand using an onboard display  31  powered by the device and operatively engaged electronic components of the computing device  43  to generate a video display feed to the display  31  and/or sound, and thereby provide users with a news feed, sports scores, interactive news, a stock ticker, a local events calendar, a photo booth, a video calling station, a Lo-jack/find my phone interface, an emergency telephone call station or beacon, or other media which may be generated by the onboard electronic equipment operatively powered by the power generated by the device. 
         [0061]    Additionally, employing the onboard power generated by the device  10 , and operative electronic components of the computing device  43  powered by the device  10 , the device may also function as an emergency broadcast system warning device to warn people proximate thereto of an immediate emergency, and emit the alarm as a visual and/or audio warning and safety instructions in such an event. Further, the device  10  using the onboard power may be configured to function as an Amber/Silver Alert notification system for people proximate to the device  10  in the event of an Amber Alert or Silver Alert communicated wirelessly to the device. 
         [0062]    As can be discerned, the device  10 , through the provision of onboard electrical power generation and storage capacity, can be easily configured by those skilled in the art, with wiring and computing devices  43  and RF wireless communications  41  and display screen  31  and audio, to provide any or all of the above functions in a single unit. Consequently, such components need not be shown in detail. 
         [0063]    Seen in  FIGS. 4-6  are differing views of the lower section  15  which is removably engageable to the upper section  13  forming the housing  11  of the device  10 . Currently preferred dimensions of the device  10  lower section  15  are shown in  FIG. 4 , including the three inch wide passage  49  communicating underneath the lower section  15 . 
         [0064]    Also shown in  FIGS. 4-6  and in  FIG. 7 , are the removably engageable mating connections for the lower section  15  of the housing  11  to the support walls  16  and  18  of the upper portion  13  of the housing  11 . The plates  39  on both the support walls  16  and  18  and the lower section  15  of the housing  11 , have apertures  43  which are aligned when the plates  39  are mated. Thereafter, removable connectors such as a nuts and bolts can be engaged through the aligned mated apertures  43 . A wiring aperture  43  is also shown for passage of operative wiring engagements therethrough. 
         [0065]    In  FIG. 8  is shown a side view of an upper portion  13  of the housing  11  which can be engaged to any lower portion  15  having the mating connections therefor. As shown the opposing support walls  16  and  18 , can be configured with a gap  50  for insertion of wall inserts  51  in-between the roof  14  and the support walls  16  and  18 . The wall inserts  51  would engage with mating connections as noted above or other mating connections such as a sliding engagement of each wall insert  51  in between a support wall  16  or  18 , and the roof  14 . Such can be by a slots formed in the mating surfaces of both the roof  14  and the top of each support wall  16  and  18  engageable by projections on each side surface of the wall insert  51 , or other means of engagement therebetween known in the art. 
         [0066]    Consequently, the angle of the roof  14  and attached solar panel  12  is abusable relative to a level surface such as the depicted bench  20 . The angle of the roof  14  may be adjusted by changing the length of either of the support walls  16  and  18  to thereby change the angle of the roof  14  when the upper section  13  is engaged to the lower section  15  of the housing  11 .
