     FIELD OF INVENTION  
       [0002]     This invention relates to improvements to roller assemblies and specifically embodied on a roller cassette to be used with closure assemblies. In one example the frame of a window assembly includes both a bug screen and a blind material provided with a replaceable roller cassette disposed within opposite jamb sections of a window assembly.  
       BACKGROUND OF THE INVENTION  
       [0003]     It is well known to provide roller blinds for windows. Typically these roller blinds are included on a roller assembly that is mounted above a typically window. The roller blind is pulled down over the window and blocks the sunlight. Normally, the roller blind is mounted on brackets that are positioned above the frame of the window or alternatively maybe installed on the frame of the window.  
         [0004]     Such an installation is inconvenient, clumsy, and unattractive. The roller blind assembly is visible at all times and may disrupt the appearance of the window and detract from decorating scheme of a particular room.  
         [0005]     Roll out screen assemblies are well known and may be provided as a supplementary assembly to be installed on a jamb of a window assembly such as those manufactured and sold by the Phantom® or screens are alternatively as sold by Preferred Engineering Ltd. including bug screen mesh installed on a roller assembly which is hidden within the hollow of a jamb of a window assembly as disclosed in the U.S. Pat. No. 6,209,610 owned by the assignee of this application. The disclosure of that application is incorporated by reference in its entirety with respect to the teachings of roll out mesh screen assemblies, from which this application claims priority and specifically from U.S. patent application Ser. No. 11/433,445 filed on May 15, 2006 a divisional of the granted U.S. Pat. No. 6,209,xxx.  
         [0006]     In the prior patent literature of Preferred Engineering there is also taught that the mesh screen material on the roll out screen assembly may alternatively be other screen like materials, for example solar screens and blind material. So, one may substitute therefore blind material for the bug mesh provided in the teachings of the U.S. Pat. No. 6,209,610. Prior filed co-pending application U.S. application Ser. No. 11/448,851 filed on Jun. 8, 2006 presently co-pending and from which this application claims CIP status, teaches in for example claim  12  that the roll out screen assembly provided in the supporting frame may include French door type assemblies wherein the screens extend from either vertical frame section and engage proximate the center of the assembly. It is further discussed that in this French door alternative one side may be blind material and the other side may include bug screen material. Applicant has discovered that this scenario would also be operative in various windows and doors assembly structures which include Applicants roller assemblies hidden within a pocket of a frame section. Applicant therefore has found that that installation would be extremely advantageous to the house holder by enabling a roll out screen assembly and a roll out solar screen assembly and a roll out blind assembly to be hidden within the pocket of window structures.  
         [0007]     Is therefore a primary object of this invention to provide a roll out cassette assembly including solar blind, bug screen and blind materials which are disposed within frame elements of closure assemblies incorporating a pocket or, alternatively a housing proximate each side of a closure assembly.  
         [0008]     It is a further object of the invention to provide a roller assembly for blind material which extends from one jamb section of the closure assembly and which also provides a bug screen roller assembly extending from the opposite jamb section of the closure assembly.  
         [0009]     It is a further object of this invention to provide the above mentioned assemblies to improve; the aesthetics of the closure assembly, and the appearance to the home owner.  
         [0010]     It is yet a further object of the invention to provide said roll out assembly which incorporates the aspect of being hidden until such time as it is desired to cover an opening in a building.  
         [0011]     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.

         [0084]     Referring now to  FIG. 20  sill  582  has a pocket P that contains screen cassette  591  with the bug screen S.  FIG. 20  illustrates bug screen S fully extended from the cassette  591  to the header  581  of the window where it is engaged by draw bar  592 ′. In this embodiment of the invention the tracks T are located on the right and left jambs  583  and  584  of the awning window. These tracks T have multiple detents D which provide multiple stops for the blind or screen.  
         [0085]     Referring to  FIG. 21  bug screen S is fully retracted into cassette  591  while the blind S′ is partially extended from its cassette  59 ′ toward the bottom part of the window. As in previous embodiments there are number of multiple positions for both rollout assemblies S and S′ forfully extended, fully retracted, and partially extended positions whereat track detents are engaged. Both draw bars  592  and  592 ′ are equipped with draw bar handles  593  and  593 ′ and latch operators  594  and  594 ′ which allows the engagement of the draw bar pins with the detents D of the tracks #. On the leading edge of each draw bar there are provided bug seals  595  which contact one another when the draw bars engage. In the alternative embodiments of the invention illustrated in  FIGS. 22 and 23  the pockets with the cassettes are located in the left jamb  584  and right jamb  583  of the assembly and the tracks T including detents D are located in the header and sill parts of the window frame  581  and  582 .  
         [0086]      FIGS. 24, 25 ,  26  and  27  illustrate a replacement screen frame assembly. Therefore the assembly  600  has a top frame member  601  a bottom frame member  602 , a right housing  603  and left housing  604 . Housing  603  contains a rollout bug screen assembly S and the housing  604  contains a rollout blind assembly S′. The bug screen assembly S illustrated in  FIG. 25  includes a draw bar  605 , draw bar handle  606  and a latch operator  607 . It also contains a bug seal  608  on the leading edge of the draw bar and additional stoppers  609  that prevent jamming of the draw bar inside the cassette housing  603  when retracted. The top and the bottom frame members shown in  FIG. 24  include tracks T for the movement of rollout assemblies including multiple detents D providing predetermined stop positions for the rollout assemblies. As mentioned previously the roll out assemblies operates in various modes, for example; a fully retracted position as illustrated in  FIG. 24 , a partially extended position near the central part of the screen frame as illustrated in  FIG. 25 . The bug screen S is shown fully extended from the cassette  603  adjacent the housing part  604  as best seen in  FIG. 26 . Blind S′ is fully extended from the housing  604  adjacent the housing  603  as best seen in  FIG. 27 . In this position the bug screen S is fully retracted into the housing  603 . Either rollout assembly might be operated to and from an intermediate position along the track of the screen frame assembly. The engagement with track T of the rollout assemblies at various positions along the tracks functions in the same manner as described and illustrated in relations to  FIG. 8 .  
         [0087]     An assembly for replacement screen frames might be installed with previously described closure assemblies such as doors or windows. The following are examples for the use of such a screen frame embodied with various door assemblies such as a French door, an entry door and a patio door. These examples are illustrative only and are not to be considered as limiting the scope of the invention.  
         [0088]     In  FIGS. 28, 29 , and  30  a replacement or add on screen assembly is illustrated attached to the frame of a French door assembly. The French door assembly contains an inside frame which consists of a header  611 , seal  612 , right frame member  613  and left frame member  614 . The screen frame previously illustrated in FIGS.  24  to  27 , is shown attached to the inside surface of the French door assembly frame. In a similar manner to the embodiment with a window assembly, the screen frame attached to the French door assembly may operate in various modes. For example,  FIG. 28  shows a partial extension of the blind S′ from the left housing to the center of the assembly with the bug screen S being partially extended from the right housing  603  to the center of the assembly.  FIG. 29  illustrates the bug screen S fully extended from the housing  603  to the left side of the door assembly.  FIG. 30  illustrates partial extension of the blind S′ from the housing.  
         [0089]     In yet another embodiment of the invention, the screen frame may be attached to the entry door assembly as shown in  FIG. 31 .  FIGS. 31 and 32  therefore illustrate an entry door with an add onscreen assembly similar to the French door embodiment. The add on screen assembly is thereof attached to an entry door frame containing header  611 , seal  612 , right frame member  613  and left frame member  614  and entry door  615 .  FIG. 33  illustrates the detents D positioned on the bottom frame member of the screenless screen. Again as in previous embodiments the add on screen frame assembly operates in various modes. For example in  FIG. 31  the screen is fully extended from the housing  603  toward the left part of the assembly and in the  FIG. 32 , both rollout assemblies are partially extended from the housing.  
         [0090]     In the same manner, replacement or add on screen assemblies may be attached to a patio door assembly as illustrated in  FIGS. 34 and 35 . The door frame assembly illustrated includes top frame member  611 , bottom frame member  612 , right frame member  613  and left frame member  614  having attached there to a replacement or add-on screen assembly as described in relation to FIGS.  24  to  27 .  FIG. 34  illustrates the use of an add-on or replacement screen assembly with a bug screen S extending from the housing part  602  toward the center of the assembly and the blind S′ extended from the housing  603  toward the center of the assembly.  FIG. 35  illustrates the bug screen S fully retracted into the housing  604  and blind S′ partially extended from the housing  603 .  
         [0091]      FIG. 36 , illustrates an exploded view of a screen cassette assembly including a jamb with an integral pocket and associated parts from the header and the sill as taught in Applicant&#39;s prior patents namely U.S. Pat. No. 6,267,168 hereby in corporation by reference. However the draw bar of the current invention is different from the one illustrated in the  FIG. 36  wherein parts  350 ′- 340 ′- 330 ′- 320 ′ are replaced by a new draw bar and latch operator with retractable pins shown in  FIGS. 42, 44  and  45 .  
         [0092]      FIG. 37  illustrates the assembly  640  of the blind S′ with the T-shape keys  643 ,  645  as described in Applicant&#39;s prior patent abovementioned hereby incorporated by reference. The T-shaped keys at the end of the blind material engage with the T-shaped cavities  649 ,  648  of the draw bar  641  and the roller  642 . As is apparent from  FIG. 37  the T-shaped keys are attached to the blind material in the following manner. The blind material S′ has numerous perforations along its sides, which perforation are inserted between the key members  643  and a supplementary portion  644 . The blind material may be optionally perforated. However it may be attached without perforations as well. These plastic members  643 ,  644  and blind S′ are attached by means of known welding techniques, by the application of heat or any other method known to persons skilled in the art. In this way the T-shaped keys are attached to any type of blind S′ regardless the type of the material.  
         [0093]      FIG. 38  illustrates the preferred T-shaped key attached to the edge of blind S′ and  FIG. 39  illustrates the preferred T-shaped key attached to the bug screens. Other key shapes are also possible as taught in Applicant&#39;s prior patent abovementioned.  
         [0094]      FIG. 40  shows how the T-shaped key members  645  and  643  fit into the T-shaped cavities  648  and  649  in the roller drum  642  and in the draw bar assembly  641 .  FIG. 41  illustrates screen S′ fully attached to the roller drum and the draw bar as previously taught in Applicant&#39;s prior patent abovementioned.  
         [0095]      FIG. 42  illustrates screen cassette assembly  511  with partially extended blind S′. It is easy to see that draw bar  512  has a bug seal  515 , handle  513  which may include a guide members  517  which guides the rollout assembly along the tracks. In addition, draw bar  512  include a latch operator  514  which controls the retractable pins  518  on the opposite ends of the draw bar. The latch operator is fully described in Applicants provisional application No. 60/689,068 incorporated herein by reference and from which this Application claims priority. The blind S′ is attached to the draw bar  512  as explained above in relation  FIGS. 37-41 , by the same means blind S′ is attached to the roller which is mounted on brackets  519  and  519 ′ for installation in the jamb pockets. These brackets allows accurate installation of the screen cassette into the pocket inside the jamb illustrated in  FIG. 43  without additional fastening means.  
         [0096]      FIG. 43  illustrates the profile of the jamb  503  and the details thereof with the pocket P as described in  FIGS. 1-7 ,  9 - 23 . Following the installation of the screen cassette  511  into the pocket P, brackets  519  and  519 ′ engage with the surfaces of the interior of the pocket P, allowing the roll out assembly S or S′ to extend from the cassette when pulling the draw bar handle to the required operating position, while the brackets are prevented from moving as taught in Applicant&#39;s prior patent abovementioned.  
         [0097]      FIGS. 44 and 45  illustrate side and front view of the latch mechanism described in Applicant&#39;s prior application No. 60/689,068 incorporated herein by reference and from which priority is claimed. The retractable square pins  518 , presented in one of numerous geometrical forms such as square, cylinder, or triangular for example, are activated by the latch operator  514 . As best seen on  FIG. 45 , by the mean of horizontal motion of the latch operator  514  pulls the pins  518  into the draw bar assembly allowing the draw bar to move along the track T. This assembly is taught in Applicant&#39;s prior priority Application abovementioned. Releasing of the latch operator  514 , the spring member  516  extends, and releases the pins  518  of the draw bar, so as to engage with one of the multiple detents D located along the tracks T as was previously disclosed above.  
         [0098]     Referring to  FIG. 46 , there illustrated an alternative embodiment of the invention including up to four roll out assemblies embodied into one add on or replacement screen assembly. Such an assembly if desired may be incorporated onto the frame of an existing window assembly or attached to the frame of a patio door assembly in the same way as has been previously described for add on and replacement screen. This assembly includes a top frame member  621  and a bottom frame member  622 . In this case the frame includes two cassette housings on each side. For the front right side a housing and cassette  624  are provided and at the back housing  623  as well. At the left side housing cassettes  625  and  626  are also provided at the back and front as well.  
         [0099]     Also shown in  FIG. 46  are rollout assemblies extending from housings  624  and  625  in a fully retracted position while the rollout screen from the housing  623 , with the draw bar  628 , is fully extended from the right side to the left and rollout screen assembly from the housing  626  with draw bar  629 , is partially extended to the right. This assembly is not a limiting one and it may for example include one bug screen in the cassette housing  623 , a solar screen in cassette housing,  625  and two blinds within cassette housings  626  and  624 , or other alternatives as desired.  
         [0100]     Referring now to  FIGS. 47 and 48  there illustrated an alternative embodiment of the invention for a tilted slide window two moveable sashes incorporating three rollout assemblies therein. This assembly resembles the embodiments of  FIGS. 13 and 14  with an additional track T′ disposed in the sill and the header behind the sashes, and an additional pocket for a screen cassette located in the left jamb  544 . The third solar screen S″ is best seen in  FIG. 48  with both sashes in a tilted and opened position.  
         [0101]     It is important to note that each cassette is sized so as to be received in a pocket for the various embodiments of the invention. Thus the cassettes are interchangeable in position for the homeowners&#39; convenience. Replacement cassettes are also readily available.
