     FIELD OF THE INVENTION 
     The present invention relates generally to sun protective devices, and more specifically, it relates to a retractable sun protector for a person with a utility solar powered USB device charging station. 
     DESCRIPTION OF THE RELATED ART 
     It is generally well known among those who work outdoors, or who are exposed for a long period of time at an open space that there are several natural or environmental enemies. The sun is one of said enemies, which when unshielded, beats down upon the head, face, ears and neck, causing sunburn. 
     Numerous sun-shade devices have been provided in prior art that are adapted to protect user&#39;s head, face and neck from the sunlight. For example, a well know device is the brimmed hat. However, the use of a brimmed hat has for that purpose is ineffective, because it prevents the flow of air between the head and the hat, resulting in the accumulation of heat. 
     Other devices, such as U.S. Pat. No. 4,112,957 and U.S. Pat. No. 4,657,037, disclose complexes and not easy retractable sun shields. Therefore, there is a need to provide an easy retractable protective device for sun exposure in order to avoid sun&#39;s damage to the worker that has the capability to provide an immediate free of cost power solution for the user, by installing a solar panel and USB connecting port above the overhead canopy, to charge mobile devices during outdoor activity.

     Referring to  FIGS. 1-3  we see an illustrative embodiment  100  of the invention, a backpack  102  having cross belts  104  adapted to extend over shoulders and/or across body of the person, wherein said cross belt comprises attaching means, such as clips (not shown) to secure the backpack to the back of the person. 
     In one embodiment, the backpack  102  has a cavity  428  within which is housed an extendable frame assembly  204  that is attached to the inside of said cavity  428 . When extended  200 , said frame assembly carries at its distal end  202  a top frame top  206  housing a canopy  208  which may have one or more deployable span extensions  302 , a neck-shield extension  304  and one ore more solar panels  306  which may be electrically connected to one or more USB or other suitable outlets within said device. 
     Referring to  FIG. 4 , we see the other components of the backpack  102 . The extendable frame assembly  204  is mechanically connected to the inside of the backpack cavity, and in one embodiment is comprised of two or more frames  402 ,  404 , comprised of a bottom frame  402  and an upper frame  404 , plus none to an infinite number of intermediate frames between said bottom  402  and upper  404  frames. The lowest portion of the bottom frame  402  (also defined as the near end of said bottom frame  402 ) is configured to be attached to the inside of the cavity within said backpack  102 . In one embodiment this may be accomplished with fabric fasteners. In an alternate embodiment, they may be attached with one or more bottom frame locking pins  406 . 
     Deploying the sun-shield is normally accomplished by pulling the extended frame assembly  204  from the cavity within the backpack  102  to its full extended position  300 , then ‘flipping’ the top frame  206  (attached to the distal end  202  of the upper frame  404  from the storage position  200  where the top frame  206  is parallel, significantly or almost parallel to the top frame  206 , for storage within the cavity when the upper frame  404  is pushed into the bottom frame  402 . The one or more rotational flipping means  210 ,  212  securing the top frame  206  to the upper frame  404  are located at the distal end  202  of said upper frame  402 . 
     In one embodiment, said rotational means are comprised of one or more rotating joints  408 . Said joints may have two positions, the stowed position (see in  FIG. 2 , where said top frame  206  is significantly parallel to said upper frame  404 ), and the deployed or open position ( FIG. 3 ), where the top frame is set at an angle. Said angle may be one significantly orthogonal to said top frame  404 , or adjustable by said user as desired. In another embodiment, the rotating joints  408  are adjustable to two or more open position angles. 
     The one or more foldable canopy extensions ( 302 ,  304 ,  306 ) are canopy material spanning the one or more folding span extensions ( 410 ,  412 ,  414 ). These span extensions have a loop or hook end  416 , so that when placed into openings along the perimeter of the top frame  206  said span extensions are designed so that when the shade is open or deployed ( FIG. 3 ), they rest at an angle that is parallel or slightly drooping to form an angled awning to the top frame  206  to the angle of the top frame. 
     When the shield is stowed ( FIG. 2 ), they spans/canopy extensions rotate so that they fold into the area of the top frame  404  for storage within the cavity in the backpack. Similarly, the neck-shield extension  310 , is located along the back of the extendable frame assembly, so that when extended and deployed, it provides protection of the rear of the neck, and when the unit is stowed, it goes into the cavity. 
     The upper frame  404  extends from the bottom frame (and any other intermediate frame members part of the extendable frame assembly) and remains in the extended position through the locking pin  418  located at said upper frame near end, engagement with the top of the bottom frame  402 . To unlock it and store it, the one or more release buttons located at the distal end of said upper member  404  are pushed (via user digit activation and/or through the folding of said top frame  206  into the stowed position  FIG. 2 , which actives one or more connecting rods  422 , which releases the locking pin  418 , allowing the upper frame to go into the bottom frame (or other intermediates frame elements, all collapsing into the backpack cavity. 
     In one embodiment, the backpack  102 , foldable canopy  424  (made of the top frame cover  426  as well as the one or more deployable foldable canopies ( 302 ,  304 ,  306 ) and neck-shield  310 ) could be made of a single or a variety of materials, sizes, styles and/or colors. Preferred materials are lightweight materials, such as, but not limited to nylon, Dacron, cotton, polyester, carbon fiber, Kevlar, and is configured to have an ergonomic shape or materials that provide a cushioned, comforting and gentle contact with the user&#39;s back and shoulders. Similarly, the extendable frame (including the bottom  402 , upper  404 , top  206  frames (as well as any other intermediate frame and other structures) could be made of similar or different materials. Preferred materials are strong lightweight materials, such as aluminum, carbon fiber, fiberglass and Kevlar, among others. 
     In another embodiment, the stowable shield  300  comprises an interchangeable flexible cover (canopy) comprising an upper cover and lower cover. The upper cover and lower cover may be integrally made or separated. Mainly, the upper cover  426  stretches over the top frame  206  and/or the lower cover covers (comprised of the foldable canopies ( 302 ,  304 ,  306 ) placed on the retractable mechanism. One or more affixing means are used to attach the cover  426 , to the top frame  206 , such as fabric fasteners, magnets, zippers and more. The fabric may include different materials. However, preferred materials are UV-resistant, water-repellent as the flexible cover. Further, the fabric may include indicia for promotional purposes. 
     In one embodiment, the left and right folding canopies ( 302 ,  306 ) of the sun shield comprise lateral covers to protect user&#39;s face from the sun and other elements, as well as to shield direct sun exposure. Such lateral shields are attached to the top and back covers by means of zippers, fabric fasteners or buttons. Preferred material for such lateral shields is see through mesh to allow visibility and ventilation, while providing the intended protection. 
     The top part of the canopy comprises a top frame  206 , lateral and front spans ( 410 ,  412 ,  414 ); wherein said spans ( 410 ,  412 ,  414 ) are configured to be fixed or adjustable as to cover a user&#39;s head, neck and shoulders. For example, the frame dimensions are wide and long enough to avoid or reduce user&#39;s exposure to sunlight, rain, snow among other elements. In the instant case, and as part of the exemplary embodiment, the top frame  206  comprises a square shape, but any other suitable shape may be used, as long as it fits within the backpack cavity. For example, the top frame  206  may double fold, making it a longer piece extending in front of the wearer. 
     In one embodiment, the upper frame  404  slides upward through the inside of the bottom frame  402  extending outside the backpack cavity, performing the deployment action and bringing with it the folded top rack  206  and canopy/solar panel. The extraction may happen via pulling on the handle  430  and or on the near side of the top frame  206  where it meets the distal end of the upper frame  404 . Storing is accomplished by pushing the upper frame into the bottom frame (as shown above), and then pressing quick pin assemblies  406  and actuating the plastic triggers. 
     In one embodiment, the displacement between said upper frame  404  and said bottom frame is completed (reaching a recessed position) by vertically sliding upward the upper frame  404 , where a quick pin assembly  418  locks the extension frame upper frame  404  at the recess position within the top or distal end of the bottom frame  402 . 
     In one embodiment the flexible cover  424  and top frame  206  when deployed are positioned above a user&#39;s head to provide the desired sun protection. Such may be accomplished by rotating the top frame  206  around the rotating joint or hinge mechanism  420  in such a way that the top frame  206  and canopy  426  are substantially parallel to the ground or ground datum when a person wearing the backpack stands. 
     In one embodiment, a solar cell  432  is mounted atop the top frame  236  and any other obstruction, so that it may be exposed to the sky ( FIG. 3 ) when the shield is deployed. The energy generated by said cell  432  is then routed via a cable down the extended frame assembly for directly charging a cellphone/tablet/PC/iPAD etc.  434  and/or into the backpack for charging a battery. In either case, the solar cell  432  may be connected to a USB/Lightning or other similar DC charger, or to an inverter to generate AC voltages. The cable coming down may be straight or coiled, to compensate for the extension of the top frame  206  away from said backpack.
