Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
       FIG. 1A  presents a front view of the closed mode of a Folding Screen Frame with movable doors hidden within the outside cover in an embodiment disclosed herein. The Folding Screen Frame comes with several components including two doors, a cover, dual hinges, screen holder and more as described hereinafter. The image shows how a left looking cross section of the left side of the Folding Screen Frame in a closed position with doors closed is presented in  FIG. 3A  for more detailed information thereof. Similarly, the image shows a center front view of the Folding Screen Frame as presented in  FIG. 3B  for more detailed information thereof. The words door or door member are herein interchangeably used. 
       FIG. 1B  presents a front view of the Folding Screen Frame with doors partially rotationally extended beyond the cover in an embodiment disclosed herein. Door members  5  and  6  are shown rotationally attached using two hinges (not shown) one for each door member  5 ,  6 ; thus, a first door member  5  is attached to aa first hinge plate through a first hinge whilst the first hinge plate itself is attached to a first side of a cover  8 . Similarly, the second door member  6  is attached to a second hinge plate through a second hinge whilst the second hinge plate itself is attached to a second side of the cover  8 ; this such that the first and second sides are opposite one another at the inside opposite ends of the cover. The two identical hinges used to so attach the two door members  5 ,  6  are attached as described with respect to  FIG. 8B . 
       FIG. 1C  presents a front view of the Folding Screen Frame with doors fully extended so that the door members extend vertically from the cover in an embodiment disclosed herein. 
       FIG. 1D  presents a front view of the Folding Screen Frame with doors completely rotated so that the doors extend vertically and with a partially deployed folding screen and associated screen holder in an embodiment disclosed herein. 
       FIG. 1E  presents a front view of the Folding Screen Frame with doors completely rotated so that the doors extend vertically and so that these are locked into position with locks associated with the deployable screen holder in an embodiment disclosed herein. 
       FIG. 2A  presents a front view of a Folding Screen Frame in an embodiment disclosed with the screen holder fully deployed and locked with the fully deployed vertical doors in an embodiment described herein. The image shows two cross section lines; a first having a top front view of the leftmost portion of the Folding Screen Frame shown in  FIG. 4A ; and a right looking cross section as shown of the entire Folding Screen Frame with screen and screen holder fully deployed with doors locked with the bottom of the screen holder as shown in  FIG. 2C . 
       FIG. 2B  presents a closeup cross section view as marked in  FIG. 2C  so as to visualize the location of the retractor wheel  13  attached to the inside top of the cover  8  and also shows the beginning of the pulley system within the Folding Screen Frame in an embodiment described herein. 
       FIG. 2C  presents the view described in  FIG. 2A  showing a right looking cross section of the Folding Screen Frame with screen and screen holder fully deployed with doors locked with the bottom of the screen holder. A section marked as  FIG. 5  shows how the screen completely extended outwards is attached to the pulley system at the inside top of the cover and attached to the screen holder inside surface. A section marked  2 B shows a closeup cross section view as marked so as to visualize the location of the retractor wheel  13  attached to the inside top of the cover  8  and also shows the beginning of the pulley system within the Folding Screen Frame. A section marked  FIG. 2D  shows the bottom of the deployed screen holder in an embodiment described herein. 
       FIG. 2D  shows the bottom of the deployed screen holder in an embodiment described herein. Here the spring plungers have their nose or ball extended to lock the door in place. Two spring plungers  18  have their barrels welded within the screen holder  4  in a first mounting hole and a second mounting hole respectively such that the first spring plunger nose is disposed facing the front of the cover whilst the second spring plunger nose is disposed facing the back of the cover. Once mounted each spring plunger is disposed such that their respective noses are movably insertable within a single one of two locking holes found near the respective ends of each respective door. When the screen holder is deployed out of the cover and reaches its greatest extension therefrom and the doors are rotated completely such that these are disposed vertically, then the doors are lockable in association with the screen holder using these locking holes found near the free ends of the doors. 
     In this manner, a front locking hole for the first spring plunger nose and a back locking hole for the second spring plunger nose engage therewith such that a first door is locked together with the screen holder; this is repeated with two other spring plungers on the other side thereby attaching the other door using two holes therein to the other side of the screen holder. Thus, their respective movable first spring plunger nose and second spring plunger nose are movable outwards to pass through a single one of these holes (a front locking hole and a back locking hole) thereby locking the doors into a vertical open mode of operation. As previously stated, the other door  6  is similarly locked into an open mode on the other side of the Folding Screen Frame. To release the locking engagement, a user would press the noses thereby detaching the door ends from the screen holder. 
       FIG. 3A  presents a side view cross section of the Folding Screen Frame in an embodiment disclosed herein. An outside cover  8  made from metal or rigid PVC is formed as an upside down U shaped member having two open ends; one at either end of the cover  8  and opposite each other. Attached to either open end of the cover  8  is a single one of two hinge plates  10  (not shown in this view but shown in  FIG. 8A-8B ) attached by welding. These hinge plates  10  serve to attach a single one of two doors, one door to each hinge plate  10  (the hinge itself is a spring loaded barrel type hinge loaded between two small wings  14 ,  15 ) using two spring hinges one for each door. Thus, a first spring hinge has a wing  14  attached to a first hinge plate  10  (welded or using screws) and the other wing  15  would attach to a door  5  (welded or using screws). The other door  6  is attached similarly to the other plate  10  at the other side of the cover  8 . 
     Within this cover  8  is a corresponding smaller U shaped member forming a screen holder  4  that is sized to fit within the confines of the outside cover  8  thereby protecting the screen  12  that it is holding from the elements. The screen is attached to a first attachment assembly that is in turn attached to the inside top of the cover  8  running along an upwardly disposed longitudinal depression. The bottom of the screen  12  is attached to a second attachment assembly that is in turn attached to the inside bottom of the screen holder  4  running along a downwardly disposed longitudinal depression therein. 
     It should be apparent from the drawings that the outer surface of the cover  8  has two inwardly directed longitudinal depressions on the front and back sides for cosmetic and aerodynamic reasons. Similarly, the screen holder  4  has a varied surface having depressions therein. The doors  5 ,  6  have similar contours having longitudinally disposed depressions. Finally it should be apparent that the spring plungers are in their closed positions with their respective noses retracted into their respective bodies as they are pushed back therein by contact with the inner surface of the doors  5  or  6  as there are no holes to engage in this view (as the rotation of the respective door has placed it in a position where there is no hole therein) which is opposite the open nose position in  FIG. 2D . 
       FIG. 3B  presents a front view of a central portion of the outside cover having two mounts; each mount is formed from a set of two small rivets mounting a plate to the cover  8 . These plates have a central hole through the plate and a corresponding hole in the metal surface of the cover  8  for welded attachment of the barrel of a spring plunger handle  17 . This spring plunger handle  17  is used to lock the cover into a closed configuration by engagement with corresponding locking holes on the front surface near the ends of either door  5 ,  6 ; thus, when the doors are rotated into position on their respective hinges this thereby moves the aforementioned each locking hole into alignment with a single central hole of the metal plate/single central hole in the metal surface of the cover; at this point the spring plunger handle  17  nose extends therethrough and locks these two together. Manipulation by (turning, twisting or pulling depending on type) of a spring plunger handle  17  causes its nose to retract thereby releasing a respective door from the cover. 
       FIG. 4A  presents a closeup front view of a top front view of the leftmost portion of the Folding Screen Frame shown in  FIG. 2A  in an embodiment described herein. 
       FIG. 4B  presents a closeup perspective view of the top leftmost portion of the Folding Screen Frame in an embodiment described herein. A cross section of a portion thereof is also shown. 
       FIG. 5  presents a closeup front view of that sectioned in  FIG. 2C  showing the screen attached to the inner top portion of the cover  8 , and the bottom of the holder  4  in an embodiment disclosed herein. Here two further sections are shown a top left section is shown directed to  FIG. 6  and a bottom left section is shown directed to  FIG. 7 . There are two retractor wheels attached to the top inner portion of the cover one for each door; these are disposed one close to one end and one close to the opposite end of the inside portion of the cover  8 . Each retractor wheel along with associated pulleys forms a separate system for opening and closing a door  5 ,  6  and extending and retracting the screen holder  4 . 
     The pulleys are threaded with the wire or cable tied to the retractor wheel and are free floating with the exception of a first pulley attached to the inner top portion of the cover  8  (using an eyebolt  2  or dedicated integral mount) and the final attachment of the wire, cable to an inner surface of the screen holder  4  (using an eyebolt  2 ). Thus, these rely on the stiffness of the first and final connection to straighten the screen  12 . The screen  12  itself is attached to the inner portion of the cover  8 , and to the screen holder  4  using either eyebolts  2  and elastic rope  3  or the pulleys connected using elastic rope  3  as described further below. 
       FIG. 6  presents a front view of a top left section of  FIG. 5  showing how the screen  12  is held to the inner top portion of the cover  8 . Here a single retractor wheel  13  is attached to the top inner portion of the cover  8  near the left side thereof. The wheel has an attached spooled wire or cable that is threaded through a series of pulleys that are free floating with the exception of a first one attached to the top inner portion of the cover  8  using an eyebolt (with an integral annular supported pulley or dedicated integral mount) and to a last fixed point attached to an inner bottom portion of the screen holder  4 . The screen  12  is itself attached along a number of its attachment points using integral annular devices to the inside top portion of the cover  8 , to various free floating pulleys  20  and to the bottom inner portion of screen holder  4 . The screen holder  4  and cover  8  attachments are accomplished using eyebolts  2  (attached by welding, threaded hole or mount to the appropriate portions of the screen holder  4  or cover  8 ) that are in turn threaded with elastic rope  3  that itself is likewise threaded into an annulus of the screen  12  and back tied to itself thereby locking these together as a loop tie. The pulleys are attached along either left or right side of the screen using annuli of the screen having elastic rope placed therein and on into an integral annular portion of a pulley and tied to itself forming a loop completing the engagement. 
       FIG. 7  presents a bottom left section of  FIG. 5  showing how the screen  12  is held to the screen holder in an embodiment disclosed herein.  FIG. 7  presents a front view of the bottom left section view of  FIG. 5  showing the attachment of the screen  12  to the inner portion of the screen holder  4  using a set of eyebolts  2  that are attached (welded, screwed into a pre-threaded hole, locked with a bolt nut combo or similar attachment mechanism) to the inner bottom portion of the screen holder  4  using screen  12  pre-installed annuli and pieces of elastic rope. These eyebolts  2  each in their own turn is threaded with an elastic rope that is also threaded within a single annulus of the screen  12  and the rope is tied to itself forming a loop; this thereby holds the screen  12  to the screen holder  4 . 
     The screen holder  4  is also movably attached to the right and left side of the screen using the cable or wire; this cable or wire is inserted onto one or more wheels of corresponding one or more free floating pulleys  20  and using a plurality of pieces of elastic rope is movably attached to screen  12 . These one or more pulleys  20  each have an end having an annular attachment point so that a piece of elastic rope  3  is placed within it and through a single annuli of the screen  12  on the right or left side of the screen  12  whereupon it is attached back to itself forming a loop through sewing, adhesive, heat treatment or other means. Upon reaching the inner bottom portion of the screen holder  4 , the cable or wire is tied onto an eyebolt that has been welded or held in place as previously described (welded, screwed into a pre-threaded hole, locked with a bolt nut combo or similar attachment mechanism) to the extreme leftmost position of screen holder  4 . A duplicate eyebolt, pulleys, elastic rope, attachment to a duplicate cable or wire is found on the right side of the inner bottom portion of the screen holder  4 . 
       FIG. 8A  presents an assembly view of the Folding Screen Frame showing how various components come together in an embodiment disclosed herein. The view also shows three other views including  FIG. 8B  at upper left,  FIG. 8C  at middle top and  FIG. 8D  at bottom left showing various features to be described herein. The cover  8  is shown separated from the two doors  5 ,  6  that rotate on hinges attached to a hinge plate that serves as end caps for the cover  8 . Additionally, the figure shows the screen holder  4  at bottom that is associated with the folding screen  12  at center. Additionally, a final trademark carrying poly extruded cap is shown above and outside of the cover  8  and hinge plate serving as an end cap  7  for the cover  8 . 
       FIG. 8B  shows how various features of the upper left of the Folding Screen Frame are assembled in an embodiment disclosed herein. It should be understood that the same features herein described are duplicated on the other side of the Folding Screen Frame. The retractor wheel  13  has a bolt  1  placed within a central hole of the retractor wheel  13  and as it exits from the hole, the bolt  1  passes into a lock washer  11  then through a fender washer  9  and on into steel rail nut  16 ; the steel rail nut  16  was slid within the rail  19  and is welded thereto. It should be understood that steel rail  19  has been welded to an upwardly centrally disposed longitudinal depression on the inside top of cover  8 . Further, the steel rail is a downwardly disposed U shaped longitudinal device whose downwardly disposed ends curl inwards towards each other creating a thin longitudinal slit. Thus, a steel rail nut  16  welded therein can not exit through this slit as it is both welded to the steel rail  19  and incapable of passing through the thin slit which is much smaller than the length, width, and or height of the steel rail nut  16 . 
     A wire or cable is wound about the circumferential surface of the retractor wheel  13  and tied thereto with a lock notch on the outer surface of one of two integral flanged surfaces; these extend from the outer surface of the retractor wheel creating a loading space for the wire or cable on the circumference of the retractor wheel  13 . The wire or cable extends further to the left and is threaded onto a wheel within a pulley  20 . This pulley  20  is attached to the inside top surface of the cover more specifically within the rail  19  that has as before had another steel rail nut  16  slid within the rail  19  and welded at an appropriately spaced distance. First the pulley has an integral annular attachment end that is attached to an eyebolt  2 ; this eyebolt  2  has an end that passes into a lock washer  11  then through a fender washer  9  and on into steel rail nut  16  that as we discussed above is placed within the steel rail  19  and welded thereto. 
     As the wire or cable exits from the pulley it passes down to another wheel pulley  20  that has an integral annular end that is attached to an annulus of the screen  12  using an elastic rope  3  attached to itself after being threaded through the screen annulus and the pulley annular end; this is repeated on down as described previously thereby creating a plurality of pulley to screen annuli attachments on both the left and right sides. Annuli are disposed about the periphery of the screen  12 ; each of the top horizontally disposed annuli of the screen  12  are attached thereto as follows. First an elastic rope  3  is threaded within the annulus and on into an eyebolt  2  whose end passes into a lock washer  11  then into a fender washer  9  and on into steel rail nut  16 ; as was discussed above the rail nut  16  is placed within the steel rail  19  and welded thereto. Finally, attached to either open end of the cover  8  is a single one of two hinge plates  10  attached by welding. These hinge plates  10  serve to attach two doors to the cover, one door to each hinge plate  10  (formed as a spring loaded barrel hinges having two small wings  14 ,  15 ). Thus, using a first spring hinge would have a wing  14  attached to a first hinge plate  10  and the other wing  15  would be attached to a door  5 . The other door  6  is attached similarly to another plate  10  at the other side of the cover  8 . 
       FIG. 8C  shows how various features of the middle cover of the Folding Screen Frame are assembled in an embodiment disclosed herein. This view presents a closeup front view of a central portion of the cover  8  having two mounts; each mount is formed from a plate attached using a set of two small rivets (through rivet holes in the plates and corresponding holes in the cover  8 ) mounting the plate to the cover  8 . These plates have a central hole through the plate and a corresponding hole in the metal surface of the cover  8  for insertion of a spring plunger handle  17  which is weld thereto. This spring plunger handle  17  is used to lock the cover into a closed configuration along with corresponding locking holes near the ends of either door  5 ,  6  when the door holes are rotated into position on their respective hinges. Each spring plunger handle  17  has a nose that extends or retracts by pulling, rotating, turning or similar modality. Thus, the nose of each spring plunger handle  17  is designed to enter through the hole in a corresponding plate and on into a hole in the cover  8  and into corresponding hole in a door  5 ,  6 . 
     The figure also shows how a screen  12  top based annulus is attached to steel rail  19  using an elastic rope  3 ; the rope  3  is threaded through the annulus and through the hole in an eyebolt  3  and tied back to itself. The eyebolt&#39;s end passes into a lock washer  11  then into a fender washer  9  and on into steel rail nut  16 . As was discussed above the rail nut  16  is placed within the steel rail  19  and welded thereto. 
       FIG. 8D  shows how various features of the bottom left of the Folding Screen Frame are assembled in an embodiment disclosed herein. Another steel rail  19  runs along the centrally disposed longitudinal depression at the inner bottom of the screen holder  4 . This steel rail in contradistinction with the one welded to the cover  8  is disposed with its longitudinal slit directed upwards, thereby forming a U shaped steel rail  19  having top ends curling inwards towards each other. Because of this, integral annuli at the bottom of the screen  12  are attached to the steel rail using the same devices as before. First, the elastic rope  3  is threaded through an annulus and through the hole in an eyebolt  2  and tied back to itself. The eyebolt&#39;s end passes into a lock washer  11  then into a fender washer  9  and on into steel rail nut  16 . As was discussed above the rail nut  16  is placed within the steel rail  19  and welded thereto. 
     Two spring plungers  18  are placed into front and back holes on the corresponding surface of the screen holder  4  and have their respective barrels welded thereto. These are used to extend their respective noses on into corresponding holes in the front and back of door  5 ,  6  thereby locking the doors into a vertical open mode of operation; this when the first spring plunger nose extends into a first hole on the front portion of the screen holder and the second spring plunger nose extends into a second hole on the rear portion of the screen holder. It should be understood that the screen holder  4  is a U shape so that the rear vertical portion of the U is the rear portion and the front vertical portion of the U is the front portion. The other door  6  is similarly locked into an open vertical mode on the other side of the Folding Screen Frame using another set of two spring plungers  18 . Pressing the noses of the spring plungers have the intended effect of releasing the doors from the screen holder  4 . A user can then use the retraction power of the retractor wheel to retract the screen holder back into the cover and lock it using spring plunger handles and the corresponding door locking holes when the doors are rotated upwards into a closed position.
