A sliding screen frame for a closure assembly, said frame comprising framing sections assembled to form the screen frame, one of said frame sections being adapted to contain a roll out screen, said roll out screen being slideable between a fully extended position, whereat the screen is substantially payed out from said roll, and a fully retracted position; wherein the screen frame is free to slide in the closure assembly whether the roll screen is at the fully extended or the fully retracted position.

FIELD OF THE INVENTION  
         [0001]    This invention relates to screens for closure assemblies and in a preferred embodiment for patio doors, and windows.  
         BACKGROUND OF THE INVENTION  
         [0002]    In the art there exists numerous devices which provide screening to prevent insects from entering open windows and patio doors. These screening devices may be placed in position within a channel provided with the frame sections of typical window or door assemblies with the screen frame of a predetermined thickness so as to easily fit within the channel. Patio door screens may be slideable in a channel on a track assisted by rollers and moveable to and from the position wherein the screen blocks the opening when the door is in the open position and prevents insects from entering the dwelling, to a position away from the opening wherein the screen does not block the opening  
           [0003]    More recently, roll out screen assemblies have been provided which include after-market products which are permanently fixed in position on or near an exterior frame section adjacent to the door opening. At this position when desired the screen may be rolled out from its housing at a fixed position and extend across the door opening when the door is in an open position. The screen of course may be accumulated on a roller in the housing and thereby provide the occupant with a clear unobstructed view of their yard. But such a construction has difficulty in providing an adequate barrier to insects. They are unsightly and are also costly and may be beyond the level of skill for a homeowner installation.  
           [0004]    Other efforts therefore have been made to make roll screen constructions more invisible and yet functional. Such constructions may be found in Applicant's prior granted patent, U.S. Pat. No. 6,267,168 which teaches the use of a roll screen cassette contained within a framing section of a closure assembly which provides guides in the header and sill frames for the leading edge of the roll screen. This construction improves the barrier against insects but raises other issues. Applicant is also aware of U.S. Pat. No. 6,167,936 that addresses a similar concept. However, such hidden constructions do require that the window frames be manufactured to required specifications to include a void wherein the roll screen may be inserted. Conceptually these patents provide a valuable approach but in one respect from an economic standpoint they require that existing window constructions be re-tooled for the required framing sections with the void for the hidden screen. Most manufacturers do not want to do this because of the cost of moulds and dies. There is therefore, still an unmet need yet unsatisfied which provides a screen construction which does not require an extensive amount of re-tooling.  
           [0005]    Attempts have been made to provide roll screen constructions within its own frame for fastening to an existing window or door frame; for example, U.S. Pat. No. 5,479,979; U.S. Pat. No. 6,082,432; and finally U.S. Pat. No. 6,070,642. Particularly referring to U.S. Pat. No. 6,070,642 as by way of example, there is taught a roll screen assembly which has a support frame which is fixed into position with the upper member ( 30 ), as best seen in FIGS. 1 and 2, including a compartment wherein the roll screen accumulates and pays out. The entire frame section therefore is fixed into position upon a typical frame for a door or a window which is adapted to the existing framing structure proximate the inner peripheral of the window or door frame. The roll screen frame is permanently fixed in position therefore and does not utilize any existing mounting portions available with the homeowner's windows or doors. Further in the case of a patio door the roll screen frame does provide an obstacle at the threshold which will be discussed hereinafter.  
           [0006]    Another example is found in such a fixed structure in relation to U.S. Pat. No. 6,082,432 wherein the roll screen frame, as best seen in FIGS. 1 and 2, is fixed in position and the roll screen is also fixed in position within the chamber compartment ( 40 ) on the brackets ( 41  and  46 ) wherein the screen pays out and accumulates. The handle portion or as it is referred to in the patent, the pulling posts ( 25 ) extends across the frame portions ( 28  and  28   b ) which are positioned in fixed relationship to span the door. Nothing within the reference teaches that the frame section supporting the roll screen may also move in relation to the door in a sliding motion as is with a typical planar screen door for a patio door (which typical screen does not include a roll screen component).  
           [0007]    Some of the problems experienced with these prior art constructions include, with respect to the roll out doors, that a framing section is provided at the threshold of the assembly. This is true, for example, for screen doors manufactured by the Phantom Manufacturing Limited under the trademark “PHANTOM”™ and by Monroe Tool and Die, and/or KSG Products for “MIRAGE”™ door screens. Typically, these products resemble U.S. Pat. No. 6,082,432 and require supplementary frame sections that extend around the door assembly which provide the obstacle adjacent to the threshold of the assembly. When the roll out screen is accumulated into the roll tube housing, the threshold remains as an obstacle to block the egress of an individual and particularly for those using wheel chairs, walkers and the like. People without particular challenges may simply step on the threshold obstacle and disform it to prevent the screen from rolling out and requiring an expensive repair. Further, such installations require expensive labour for installation and may be quite expensive in comparison to a typical sliding screen door which is not fixed in position.  
           [0008]    Applicant is also aware of a product SCREEN AWAY™ for retractable roll screen assemblies manufactured by Superior Building Products which provides such a device which includes approximately 18 to 24 parts and 22 steps involved in assembling the kit of components provided. Although the product may be esthetically pleasing once assembled, the threshold obstacle is evident which must be present to provide support for the leading edge of the roll screen as it moves across the opening.  
           [0009]    However, a typical known sliding screen frame, for installation adjacent a patio door, when positioned across the patio door opening blocks the occupants view of the yard and may be esthetically displeasing. If the screen door is slid to the opposite position away from the opening then the opposite glass pane is obstructed as well.  
           [0010]    None of the prior art constructions identified above known to Applicants addresses the issue which Applicants' current invention focuses in upon. That is with all of the knowledge of those designing roll out screen assemblies which are bolted in place whether or not in a frame, none of the inventors including Applicant's prior construction take advantage of the existing channels and tracks within windows and patio doors to allow for simplicity of installation to easily fit within known constructions for windows and patio doors.  
           [0011]    Applicant therefore is providing a roll screen frame construction, which is standardized at its perimeter to mate and interfit with well known channels, tracks and hardware. In doing so the present roll screen design makes replacement and installation much simpler. In spite of the numerous efforts made to provide an acceptable roll screen for windows and doors there still remains a long felt need left unaddressed in the art for a roll screen assembly which may be simply and easily installed by the homeowner. Nowhere within the prior art is such a roll screen frame provided which may be merchandized as an OEM as well as an after-market product and which will fit the same constraints provided with windows and doors such as for example the well known planar screen frame which slides in a track in a frame adjacent to a patio door. These particular known frames are inexpensive.  
           [0012]    It is therefore a primary object of the invention to provide a roll screen frame construction, which is standardized at its perimeter to mate and interfit with existing well known channels, tracks and hardware for windows and doors.  
           [0013]    It is yet another object of this invention to provide a sliding screen frame with integral roll screen housing which frame may be slid across the opening of a closure frame and which frame is also used to support the free end of the roll out screen as well.  
           [0014]    It is another object of the invention to make such a roll out screen assembly affordable.  
           [0015]    It is yet a further object of the invention to provide a screen assembly in a fully assembled or alternative knock down kit form which is easy to assemble and/or install.  
           [0016]    It is yet a further object of the invention to provide a screen assembly which may be provided as a kit of components.  
           [0017]    It is yet a further object of the invention to provide a screen assembly which is cost effective.  
           [0018]    Further and other objects of the invention will become apparent to those skilled in the art when considering the following summary of the invention and the more detailed description of the preferred embodiments illustrated herein.  
         SUMMARY OF THE INVENTION  
         [0019]    Reference to a roll screen assembly within this specification is to be defined as also including any screen construction which pays out from and returns to a housing whether a roll screen installed with or without a roll tube, or whether the screen is pleated in an accordion like fashion or the like or any other similar screen construction without limitation. When the term screen is utilized its is intended that other matrices such as shades, blinds, and screens whether transparent, opaque, mesh or the like is implied without limitation.  
           [0020]    According to a primary aspect of the invention there is provided a screen frame construction for a closure assembly, preferably a roll screen, comprising framing sections having an outer perimeter side and an inner side, and a screen housing from which a screen is payed out and accumulated, said framing sections being adapted proximate the outer perimeter side to interfit with, preferably existing well known, channels, tracks and hardware for windows and doors, and said framing sections being adapted proximate the inner side to provide a guide and support for the screen as it is payed out from the housing.  
           [0021]    According to yet another aspect of the invention there is provided a sliding screen frame for a closure assembly comprising framing sections having an outer perimeter side and a screen housing from which a screen is payed out and accumulated, wherein said framing sections are adapted proximate the outer perimeter side to interfit with the track of the closure assembly to enable the screen frame to slide across the opening of the closure assembly and the frame sections also being adapted to support the free end of the screen as it is payed out and accumulated.  
           [0022]    According to yet another aspect of the invention there is provided a sliding screen frame for a closure assembly having an opening, said screen frame being moveable between a position wherein the screen frame is in an opening blocking position to second position wherein one is free to pass through the door opening, said screen frame comprising framing sections having two sides, and a housing wherein a screen is accumulated and payed out, preferably a roll out screen, said framing sections having two sides, a first side adapted to receive the free end of the screen, and the other side adapted to engage with channels, tracks, hardware or the like of the closure assembly, wherein said screen has a free end being moveable across the screen frame from an accumulated position within the housing, and preferably disposed on a roll, to a fully payed out extended position, the free end of the screen riding within the first side of the framing section.  
           [0023]    According to yet another aspect of the invention there is provided a preferably slideable screen frame for a closure assembly, said frame comprising framing sections and a housing for paying out and accumulating a screen, and preferably a roll screen, said framing sections have a first and second side, the screen being moveable and guided by the first side of the framing sections between a fully extended position, whereat the screen is substantially payed out from said housing, and a fully retracted position within the housing; wherein the screen frame is adapted, proximate the second side of the framing section, to engage with and preferably slide in the, preferably existing channel, track or hardware disposed with closure assembly whether the screen is at the fully extended or the fully retracted position.  
           [0024]    According to yet another aspect of the invention there is provided a sliding screen frame comprising frame members including an integral roll out screen housing, said frame members being adapted to allow said frame to slide across a closure frame as well as providing a support for the free end of the roll out screen. In one embodiment said frame includes rollers or wheels preferably located proximate the top and/or bottom of the frame to assist with the sliding motion of the screen frame across the closure frame opening. Preferably the rollers or wheels are included with a support bracket for supporting the roll screen in said housing. In one embodiment the preferred bracket may also include a section to engage the frame member proximate the corners to assemble the members into the screen frame and to house the roller for movement on the track of header and sill of the closure assembly. Preferably the bracket also includes supports within the brackets opposite the rollers or wheels to engage the roll tube of the roll screen.  
           [0025]    It is not necessary in all embodiments that the screen frame be slideable within conventional constructions such as channels, tracks, and the like. The essence of the invention is therefore that the screen frame includes framing sections and a screen housing, and that each section includes an inner portion adapted to be used as a guide for the free end of the screen and an outer portion adapted to engage with and in one embodiment slide in the preferred existing channel, track or hardware disposed with closure assembly whether the screen is at the fully extended or the fully retracted position.  
           [0026]    The invention therefore also includes a frame member for a screen frame including a housing from which a screen is payed out and accumulated, said member comprising a first portion adapted for engagement with, preferably conventional existing, window and door frame hardware, channels, tracks and the like; and a second portion adapted to guide the free end of the screen.  
           [0027]    Therefore, to these ends according to another aspect of the invention, there is provided a kit of components for a screen frame comprising framing members, a screen housing, and a screen contained in and payed out from said housing, said framing members being firstly adapted engage with, preferably conventional existing, window and door frame hardware, channels, tracks and the like; and also being adapted to guide the free end of the screen. The first adaptation of the frame members is to provide engagement of the screen frame of the present invention with known constructions which presently engage known screens for doors, windows and patio doors, 1) such as a typical rail used with patio doors which includes a rail or the like which engages a sliding mechanism, usually a roller; or 2) such as a typical lift out screen arrangement for windows including a generally u-shaped flange for acceptance of a screen frame; or 3) such as a typical casement screen channel with engagement pins which are rotated out of position to allow screen removal; wherein the present invention is unlike the prior art constructions not permanently attached which can be readily replaced and attached by a home owner. Therefore a kit of components may be provided which includes the framing sections and the housing and roll screen which may be assembled to provide the above-mentioned screen frame. Of course the screen frame may also slide which has been described above. This however, is not absolutely necessary. The need that is being satisfied is that the present invention allows for replacement of existing screens using the same channels, rails and/or hardware provided for existing assemblies wherein the present invention is adapted to fit those channels, rails and/or hardware allowing the home owner the ease of installation without providing the requirement of an expensive installer and retro fitted parts.  
           [0028]    According to yet another aspect of the invention there is provided a support bracket for a roll screen which comprises a support for said roll screen proximate one end of the bracket and an integral mounting part for a roller or wheel proximate the other end of the bracket. Preferably the bracket may be made from nylon, plastic, Delrin® or the like.  
           [0029]    The framing members may be formed from nylon, plastic, steel, aluminum, fiberglass, PVC or the like by any conventional method including roll forming, pultrusion, extrusion, CNC fabrication, with no limitation being implied whatsoever.  
           [0030]    When the term conventional and or existing hardware, channels, tracks or the like is used in this specification with reference to the various aspects of the invention described above it is implied that such hardware, channels, and tracks are utilized to secure existing planar screens found in windows, doors, patio doors and other closure assemblies whether existing, replacement or original assemblies such as but not limited to tilt and slide windows, casement windows, double hung windows, awning windows, pivoting doors, and patio doors. Further it is intended that the screen assembly of the various embodiments of the invention may be easily and simply placed or dropped into position with a minimum of effort without requiring fastening in position with the exception of rotating or retracting a holding pin or the like or making a tension adjustment to the roller. Conventionally hardware channels and/or tracks or the like are located with the various assemblies discussed above to allow this simple installation. The homeowner can therefore use conventional existing hardware for installation of the various embodiments of the present invention or alternatively if desired can provide replacement hardware which may be of any compatible shape or configuration or which may engage the conventional hardware or alternatively may replace it. Simplicity of replacement or installation is the key for our screen assembly.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0046]    Although the following description focuses on a patio door screen, it is not intended that the invention be limited in this aspect. The invention also may be embodied with other doors, windows, or the like. Those skilled in the art will recognize these other uses without limitation.  
         [0047]    Referring generally to the figures, there is illustrated a screen frame assembly ( 10 ) which includes a screen housing ( 14 ) and frame sections ( 11 ,  12 , and  13 ) making up the frame ( 10 ). The assembly ( 10 ) slides within an opening of a closure assembly such as a patio door. The sliding action of the screen frame ( 10 ) is accomplished by sliding the screen frame along the edges ( 11   b  and  13   b ) within tracks or channels normally found within a patio door assembly. These channels are found in the sill and the header of the door assembly. The screen frame ( 10 ) therefore moves as is known in prior art sliding constructions. However, integral with the framing section ( 10 ) is a compartment ( 15 ) within which is found a spring biased roll screen assembly. As best seen in FIG. 2, the leading edge ( 31 ) of the screen ( 30 ) travels within the inside edges ( 13   a  and  11   a ) of the frame portions ( 11  and  13 ) to and from a fully accumulated position wherein the screen is accumulated on the roll tube which will be described hereinafter, to a fully extended position wherein the leading edge ( 31 ) is located proximate the channel portion ( 12   a ) adjacent the interior of section ( 12 ) which screen edge ( 31 ) may be latched and/or locked in position. Whether the screen ( 30 ) is at the fully accumulated or the fully extended position, the entire screen assembly ( 10 ) may be slid across the patio door opening. In this manner, the screen is slid out of a position where it might block the threshold to an occupant. This allows passage of wheel chairs, walkers and the like in a simple manner and overcomes one of the problems in the art.  
         [0048]    As best seen in FIGS. 3 and 4 the portion ( 13   b ) of section ( 13 ) has opening (b) therein to be received in standard sized channels or rails provided in the sill and header frames of the track assembly. The leading edge of the screen ( 31 ) will slide or be guided via guide (G) within the section ( 13   a ) within channel (a) thereof as described above and hereinafter to assist motion of the leading edge ( 31 ) of the screen ( 30 ).  
         [0049]    Rollers (R) may be provided with the brackets ( 21  and  20 ) at mounting slots ( 20   d ) and ( 21   d ) which rollers travel within the sill track. They also may be provided for brackets ( 22 ) and ( 23 ) for the header. The bracket portions ( 20 ,  21 ,  22  and  23 ) also provide channel portions ( 20   a,    21   a,    22   a  and  23   a ) which marry within the track portions of the closure assembly and which assist with the assembly of the screen frame  10 . As seen in FIG. 11 a  leg portions (d) and (f) for brackets ( 20  and  22 ) and ( 21  and  23 ) respectively interfit in channels (b), (d′) and (b′) respectively to assemble the frame sections ( 11 ,  12  and  13 ) with the housing ( 14 ). The brackets also provide extensions for example, track portion ( 13   b ) and providing a channel (b) to receive the track disposed within the sill and header of the rails normally provided. The roller (R) therefore is spring biased as is known to accommodate various tensions. Release pins may be provided, as is known, within the legs of brackets ( 21  and  23 ) to allow installation and replacement of the screen frame in a similar manner as conventional planer screen frames, which are known in the art. The brackets ( 22  and  20 ) support the roll screen assembly (S) therebetween mounted on a tube. The tube has a slot in it to receive one end of the screen with the other end of the screen being proximate the exit from the tube housing ( 15 ) as best seen in FIG. 14 at ( 15   c ). The brackets ( 20  and  22 ) as best seen in FIGS. 6, 7,  8  and  9  have holes therein for aligning with holes (y) within the housing ( 14 ) to align the portion ( 22   z ) with portion ( 15   b ) and receipt of threaded screws. The mouth ( 15   c ) therefore of the cover ( 15 ) allows for the free end ( 31 ) of the screen assembly ( 30 ) to extend therefrom. Locking portions ( 22   c ) provide locking of the roller tube in position.  
         [0050]    When fully assembled the screen assembly ( 10 ) therefore can replace an existing sliding screen utilizing the same channels of the existing patio door. This enables the homeowner to effect the replacement without the need for an experienced installer or add on supplementary components. No assembling is required. The screen assembly  10  merely drops into the existing channels.  
         [0051]    As can be seen from the Figures, the present invention resembles the well-known prior art sliding patio door screen in that it may be slid from a position where it fully covers the door opening to a position where it does not. However, it clearly has the added advantage in that the screen may be accumulated on the roller when the entire frame is at the first position so that it does not block the view of the occupants when the patio door is in fact closed. However, when the patio door is open, the roll screen may be extended to the fully extended position and latched thereat so as to prevent insects from entering the dwelling. However, when an occupant wishes to exit the dwelling, the patio screen assembly ( 10 ) may be slid in a conventional manner so as to not obstruct the threshold as is the case with prior art structures discussed in the background of the invention. The framing sections ( 11 ,  12 ,  13  and  14 ) may be made from aluminum extrusions or the like, and the brackets ( 20 ,  21 ,  22  and  23 ) may be manufactured from nylon or other resins. Section  14  may be an aluminum extrusion as well.  
         [0052]    The entire assembly may be provided in a kit of components wherein all of the framing sections ( 10 ,  11 ,  12 ,  13  and  14 ), brackets ( 20 ,  21 ,  22  and  23 ) housing ( 14 ) and the roller screen assembly may be provided in the kit which may be easily assembled. When compared to the prior art constructions of PHANTOM™ or MIRAGE™, instead of the typical 22 steps in order to provide such a prior art construction which typically is done by an expensive installer, the present roll out screen will be marketed for substantially the same price as the well-known standard sliding planer screens in various consumer outlets and may be used to replace standard screens when they are in need of repair.  
         [0053]    Further Applicants may utilize the flexible screen connectors of FIG. 14 in the screen assembly ( 10 ) as taught in its prior patent technology referenced above, using a roll tube having a compatible detent therein and handle portion having compatible detent therein for receiving the flexible T-shaped connector at each end of a screen cloth which may therefore may accommodate easy screen replacement. It is required that the same dimensions (length, width and thickness) be utilized for the threshold and header track engaging framing portions ( 11  and  13 ) as those which are standard at the present date. This will allow for easy replacement of the conventional planer screen with the present invention. As is taught in Applicant's prior invention the tube may be tensioned by the means as disclosed therein.  
         [0054]    Referring now to FIGS. 10, 10 a,    11 ,  11   a,    11   b,  and  14  there is illustrated the assembly ( 10 ) of FIG. 1 engaging top rail (R T ) bottom rail (R B ) proximate the top thereof (L). Conveniently therefore the sections ( 11 ) and ( 13 ) are provided having openings or channel sections as best seen in FIGS. 3 and 4 at ( 11   a ) and ( 11   b ) and ( 13   a ) and ( 13   b ) which as best seen in FIG. 11 defining the top and bottom sections of the screen assembly ( 10 ) which now includes the housing for the roll out screen (S) and the frame sections ( 11 ) and ( 13 ) which includes an upper and a lower section or profile ( 11   a ) and ( 11   b ), ( 13   a ) and ( 13   b ) respectively. The inside portions ( 11   a ) and ( 13   a ) are for the receipt of the legs (d) and (f) of the brackets ( 20 ,  21 ,  22  and  23 ) to close the frame sections and integrate the entire assembly by attaching the housing and roll screen thereto. Clearly, as can best be seen in FIG. 10A the roller (R)  24 ¢, engages the rail (R B ) proximate the top thereof (L) in a conventional manner, said roller being provided with the brackets ( 21  and  20 ) and preferably ( 23  and  22 ) as previously described in relation to FIG. 2. The patio screen assembly ( 10 ) will therefore be free to roll upon the rails (T, R and B) in a conventional manner. However, the sections ( 11  and  13 ) also include sections ( 13   a  and  11   a ) for receipt of and the carriage of the guide (G) for the handle (H) of the screen assembly accumulated on the tube (T) advanced via handle (H) to the guides ( 11   a  and  13   a ) to proximate the section opening of ( 12   a ) where at the handle may be latched. The latch is not illustrated nor described and would be as is known. The brackets therefore in combination with the framing sections ( 11 ,  12 , and  13 ) provide, along with housing ( 14 ), an integrated screen frame which will slide along the known rails in a patio door closure assembly with the guides (G) attached to handle (H) via the legs which extend upwardly and downwardly into the opening provided in the handle with the handle being engaged with the T section shown in FIG. 14 at (S 2 ) attached to the screen and the handle at ( 305   y ) and to the tube at ( 305   x ) via T section (S 1 ). As seen in FIG. 11 b  the tube is attached to bushings (B 1  and B 2 ) which are subsequently attached to the pins provided with each bracket ( 20  and  22 ) to allow for the rotation of the tube. The bushings therefore provide for the pivoting of the tube while the spring is attached to the pivot ( 20   b  and  22   b ) and allows for pre-winding of the roller screen to a pre-determined tension to ensure that it will return to its fully accumulated position.  
         [0055]    Referring now to FIGS. 12 and 13 there is illustrated examples of the various forms which the present invention may take without intending any limitation being derived by the reader in providing these examples. With regard to FIG. 12 there is illustrated corresponding sections found in prior art installations typical for a slider window, for example A, wherein a channel is provided within which a typical screen frame fixed in position. However, the screen frame blocks the view of the individual as it is permanently placed in position until such time as it is removed. As seen in FIG. 13A, the present invention provides for a combination of the screen including a frame which engages the same channel section in the prior art window of FIG. 12A, and yet provides with the same frame section, the movement of the roll screen to and from the housing ( 14 ) to allow for the occupant to have the screen in place when the window is open and have the screen out of view when the window is closed. This may be accomplished utilizing the same window channel provided in known window and typically slider window constructions.  
         [0056]    Referring now to FIG. 12B, there is illustrated a typical rail of a patio door having a section (L) which engages a roller attached to a frame section which also has permanently installed therewith a screen. With regard to FIG. 13B, the present invention includes and provides with the framing section and the assembly  10 , as seen and described in relation to the prior figures, a roller within section ( 13   b ) which engages the known rail (L) within channel section ( 13   b ), and wherein in addition the free end ( 31 ) of the roll screen is movable within the channel ( 13   a ) of Section  13 . The same advantages are described in relation to FIG. 13A and are realized therefore as well with the patio door screen embodying the invention. The screen frame may roll on the rail (L) and the screen may be guided to and from an accessible position to a position wherein the screen is out of view.  
         [0057]    Referring now to FIG. 12C or  12 D there is illustrated a typical casement window planer screen which is attached to a framing section permanently and would permanently block the view of an occupant through the casement window. The planer screen is released via a pin release in FIG. 12C or with a pivot pin in FIG. 12D moved in the directions indicated. Utilizing the same channels and stops therefore the present invention in FIGS. 13C and 13D provide for placing of a casement screen of the present invention in exactly the same manner as with the prior art constructions with the additional combination heretofore unknown of the framing section ( 13 ″) including portions ( 13 ″ b ) for engaging the known hardware within the frame section and section ( 13 ″ a ) for providing for the guiding channel of the free end of a roll out screen assembly which has been integrated therewith.  
         [0058]    As is normally required it is highly recommended that sealing portions (not shown) be provided for sections  12  and housing  14  disposed along the entire outside vertical edges thereof.  
         [0059]    Referring now to FIGS. 1A, 2A,  3 A,  4 A,  6 A,  7 A,  8 A,  9 A,  10 B,  10 C,  11 E and  11 D there is illustrated the screen assembly ( 100 ) similar in all respects to screen assembly ( 10 ) as previously described with the difference being that the screen assembly ( 100 ) does not roll or slide within a track. The screen assembly ( 100 ) which includes sections ( 111 ,  112 ,  113 ) and housing ( 114 ) supported on brackets ( 120  and  122 ) and further assembled with the assistance of brackets ( 121  and  123 ) consistent with the previous patio door example, and utilizing the similar bracket ( 122 ) for example in FIGS. 6A and 7A which includes a leg ( 122   x ) which will be inserted within the framing sections ( 113  and  111 ) to assist with the assembly of the embodiment. As best seen in FIGS. 11C, 11D and  11 E the conventional u-shaped section ( 200 ) is provided in a window assembly frame to which the window screen ( 100 ) will engage in a manner as shown in relation to FIGS. 10B and 10C consistent with previously described patio door embodiment with the section ( 200 ) being engaged by the leg ( 122   b ) of the window screen ( 100 ) having a roll screen as seen in FIG. 11E contained within the housing ( 114 ) identical to FIG. 11A in all respects except that it is now a window screen as opposed to a patio door screen. Therefore, FIGS. 11B and 11E are comparable and the reader is referred thereto for like parts, and the operation thereof with the exception of the sliding. The descriptions are very much the same. The essence therefore, is that the window screen assembly ( 100 ) will interfit within the frame section ( 200 ) provided adjacent the header and sill of a window closure assembly with the invention ( 100 ) including the roll out screen within housing ( 114 ) being guided via guides (g) within frame elements ( 111   a  and  113   a ) to and from the accumulated and the employed position. When the window screen requires replacement or repair, it can easily be removed from the channel ( 200 ), repaired or replaced by dropping the new screen or repaired screen in position.  
         [0060]    The window embodiment of window screen ( 100 ) may also be utilized with the other examples provided in FIGS. 13A, B and C. A man skilled in the art would understand what minor modifications would have to be made to do so.  
         [0061]    Therefore, in essence the present invention provides for a combination of features heretofore unknown allowing for installation of the various forms of the invention within the hardware and channel portions already provided with known window constructions, patio door constructions, and casement window constructions. The illustrations and descriptions in relation to FIGS. 12 and 13 are for illustrative purposes only and in no way limit the invention.  
         [0062]    As many changes can be made to the preferred embodiments of the invention without departing from the scope thereof. It is intended that all matter contained herein be considered illustrative of the invention and not it a limiting sense.
