Description:
BACKGROUND 
       [0001]    This invention relates to a reconfigurable shade, and more particularly to a removable screen or panel that is magnetically moveable along a window or other surface using the inherent metal embedded in the environment, such as corner bead or steel beams around windows or doors. 
       SUMMARY 
       [0002]    The present invention is directed to a magnetic removable screen system. 
         [0003]    In an implementation, the invention relates to a removable screen apparatus with a plurality of magnetic fasteners and a formable material, where the formable material has at least two opposing sides that are configured to receive one or more of the magnetic fasteners in each of the opposing sides. 
         [0004]    In one implementation, the magnetic fasteners are magnetic strips that can be continuous along one or more sides of the formable material. The magnetic strips can also be continuous along the entire perimeter of the formable material. 
         [0005]    In another implementation, the magnetic fasteners are individual magnets or magnetic disks that can have various shapes, for example, they can be spherically shaped. The magnetic fasteners can be distributed along the perimeter of the formable material, throughout the surface, or in the corners of the formable material. The magnetic fasteners can be distributed evenly, in a pattern, or randomly. The magnetic fasteners can also be distributed in a tessellation pattern. 
         [0006]    In various implementations of the invention, the formable material can be penetrable by light, partially penetrable by light or impenetrable to light. The formable material can be a solar screen. The formable material can also be permeable to air or impermeable to air. Further yet, the formable material can be permeable to water or impermeable to water. The formable material can also be fire resistant. The formable material can also be flexible, semi-flexible, semi-rigid or rigid. The formable material can also be reusable origami paper and can be formed into three-dimensional shapes. In yet further implementations, the formable material can be a textile, plastic or an insect screen. The formable material can also be nonflammable. The formable material can also include fiber optic lights or a photovoltaic solar cell circuit for an illuminated solar shade. 
         [0007]    In another implementation, the invention relates to a removable screen system with a plurality of magnetic fasteners, a formable material having one or a plurality of receptacles for receiving the magnetic fasteners, and an attachment surface external to the formable material that is magnetically compatible with the magnetic fasteners and where the formable material is movable along the attachment surface. 
         [0008]    In implementations, the receptacles can be pockets, folds, adhesives or other types of means for securing the plurality of magnetic fasteners. In some implementations, the attachment surface can be integral to a window, a wall, a ceiling, or another type of surface. The attachment surface can also be affixed to a window, wall, ceiling or other type of surface, for example by means of screws, snaps, tacks or adhesive. The attachment surface can also be removable. The attachment surface can include a magnetic material or a ferromagnetic material. 
         [0009]    In further implementations, the attachment surface can be a track or a strip of material, or any other shaped surface. The attachment surface can also be a ball bearing or roller bearing. The attachment surface can also be an electric magnetic track or a curtain rod with magnetic or ferromagnetic properties. 
         [0010]    In implementations, the formable material slides along the attachment surface. In other implementations, the formable material rolls along the attachment surface. 
         [0011]    In implementations, the formable material can be rectangular, circular, a polygon, or any other geometric or non-geometric shape. In further implementations, multiple pieces of the formable material can connect to form layers or larger panels. 
         [0012]    The invention can be used as a window shade, for example, to partially or completely block light, air, or insects. The invention can also be used as a room divider or a projection screen. 
         [0013]    One or more implementations of this invention have the following advantages: implementations of the invention do not use hanging cords or rods that can cause injury, especially to small children; the installation is fast, easy and simple without the need for additional tools or mechanisms; implementations of the invention are transformative and interactive; implementations of the invention minimize damage to walls by eliminating the need for drilling holes; implementations of the invention are easily removable; implementations of the invention are simple and inexpensive; implementations of the invention can provide a variety of functions including privacy, light control, airflow control, temperature control, decoration, interactive sculpture and innovative design; implementations of the invention can be used as a window shade, a room divider, a projection screen, an artistic display, or as part of an installation; implementations of the invention can include solar panels and can be used to reduce the carbon footprint of a building; implementations of the invention can also be used to illuminate a building.

Each of the magnets  137   a - l  and  139   a - c  can be coupled to removable screen  110  by means of an individual receptacle or groups of magnets can be coupled by means of the same receptacle. Receptacles can include pockets, fasteners, or any other mechanisms or means that can receive a magnet. 
         [0041]    Magnets  137   a - l  and  139   a - c  can be coupled to removable screen  110  such that they are not visible from a given perspective of the formable material. Receptacle  127  and any other receptacles can also be kept out of view. 
         [0042]      FIG. 2  shows a fold line between each pair of magnets  137   a - l  and  139   a - c , for example, fold line  141   a  between magnets  137   g  and  137   d,  and fold line  141   b  between magnets  137   g  and  139   c.  These fold lines will be discussed in more detail below. 
         [0043]    A removable screen, such as removable screen  10  or removable screen  110 , can be magnetically coupled to a window or other frame by the magnetic attraction of the magnets within the removable screen to magnetically compatible elements such as corner bead. In the absence of corner bead or other property within a window or frame that would result in magnetic attraction of the magnets within the removable screen to the wall or screen, the removable screen can be magnetically coupled to a window or other frame by means of an attachment surface. Referring now to  FIG. 3A , attachment surface  60  is coupled to a window  50 . Attachment surface  60  is a continuous strip of material along window edges  51 ,  52 ,  53  and  54 . Attachment surface  60  is made of magnetic, ferromagnetic or other material that would result in magnetic attraction to the magnets within a removable screen. Attachment surface  60  can be permanently affixed to window  50 , for example by means of screws or permanent adhesive or can be attached by removable means, such as Velcro, pins, tacks or a removable adhesive. As illustrated in  FIG. 3A , attachment surface is a continuous strip of material but can also include multiple strips of material or individual small pieces of material distributed where needed, for example, at corners  50   a,    50   b,    50   c  and  50   d  of window  50 . 
         [0044]    Referring now to  FIG. 3B , a side view of a removable screen system  800  is shown. Attachment surface  860  is coupled to frame  870  of window  850 . Removable screen  810  includes magnets  837   a - g , which are magnetically coupled to attachment surface  860 .

         [0046]    Referring now to  FIG. 3D , a side view of a removable screen system  1000  is shown. Frame  1070  of window  1050  includes corner bead (not shown in  FIG. 3D ), or other material embedded within window  1050  capable of magnetic attraction, therefore an attachment surface is not needed. Removable screen  1010  includes magnets  1037   a - 1037   g,  which are magnetically coupled to frame  1070 . 
         [0047]    Referring now to  FIG. 3E , a side view of a removable screen system  1100  is shown. Frame  1170  of window  1150  includes corner bead (not shown in  FIG. 3E ), or other material embedded within window  1150  or frame  1170  capable of magnetic attraction, therefore an attachment surface is not needed. Removable screen  1110  includes a continuous magnetic strip  1180 , which is magnetically coupled to frame  1170 . 
         [0048]    Referring now to  FIG. 4A , the removable screen arrangement  200  is an example of a horizontal Roman shade arrangement of the removable screen  10  of  FIG. 1  or removable screen  110  of  FIG. 2 . Removable screen  210 , as illustrated in  FIG. 4 , has a rectangular shape and has a top edge  211 , a right edge  213 , a bottom edge  215  (not shown in  FIG. 4 ) and a left edge  217 , is coupled to window  250 . Removable screen  210  includes a plurality of magnets (not shown in  FIG. 4 ), as discussed in  FIG. 1 . For aesthetic purposes, some or all of the magnets can be kept out of view. In particular, there is at least a magnet  237   a  at corner  229 , a magnet  237   e  at corner  231 , a magnet  237   g  at corner  233 , a magnet  237   k  at corner  235 , magnets  237   b  and  237   c  along right edge  213 , and magnets  237   i  and  237   j  along left edge  217 . 
         [0049]    Removable screen  210  is magnetically coupled to window  250 . Removable screen  210  can be magnetically coupled to window  250  by virtue of corner bead that is embedded within the frame of window  250 , which is commonly found in many households. Alternatively, removable screen  210  can be magnetically coupled to window  250  by means of an attachment surface  260  (not shown in  FIG. 4 ), as discussed above. 
         [0050]    Arrangement  200  is achieved by first magnetically coupling removable screen  210  to window  250  such that right edge  213  of removable screen  210  is parallel to the right edge of window  250 , that left edge  217  of removable screen  210  is parallel to the left edge of window  250 , and that removable screen  210  lays flat on top of window  250 , as shown in  FIG. 1  or  FIG. 2 . Magnets  237   b  and  237   j  slide up along the left and right edges of window  250  to create fold  251  in removable screen  210  as shown in  FIG. 4 . Similarly, magnets  237   c  and  237   i  slide up along the left and right edges of window  250  to create fold  253 , and magnets  237   e  and  237   g  slide up along the edges of window  250  to create fold  255 . 
         [0051]    Referring now to  FIG. 4B , the removable screen arrangement  300  is an example of a vertical Roman shade arrangement of the removable screen  10  of  FIG. 1  or removable screen  110  of  FIG. 2 , and is achieved similarly to arrangement  200  of  FIG. 4A , that is, by sliding pairs of magnets  337   b  with  337   j,    337   c  with  337   i,    337   d  with  337   h,  and  337   e  with  337   g,  along the edges of window  350 , to create folds  351 ,  353 ,  355  and  357 . 
         [0052]    Referring now to  FIG. 5 , removable screen arrangement  400  is an example of another arrangement of removable screen  10  of  FIG. 1  or removable screen  110  of  FIG. 2 . Arrangement  400  is achieved by first magnetically coupling removable screen  410  to window  450 , but unlike arrangements  200  and  300  of  FIGS. 4A and 4B , arrangement  400  is achieved by lifting pairs of magnets  437   c  with  437   i,  and  437   d  with  437   h  and placing them along the edges of window  450  to create fold  451 . 
         [0053]    Referring now to  FIG. 6 , removable screen arrangement  500  is an example of a side roll arrangement of removable screen  10  of  FIG. 1  or removable screen  110  of  FIG. 2 . Arrangement  500  is achieved by starting with removable screen  510  flat on top of and magnetically coupled to window  550 . Instead of sliding magnets, magnets are lifted and joined with other magnets to create rolls or folds. For example, referring to  FIG. 6 , magnet  537   a,  which is coupled to the upper right corner  529  (not shown in  FIG. 6 ) of removable screen  510  and to the upper right corner  550   a  of window  550 , is lifted.
