Title: Window brackets for providing efficient removal of window screens

Description:
BACKGROUND 
     Headrails for window blinds may be mounted in a window opening by attachment either to the window frame, by an end mount to the inner walls of the window casing, or by an overhead mount to the upper wall of the casing or the ceiling adjacent to the window. Brackets may be used to attach the headrails to the window frame. These brackets may have holes in them through which screws may be driven such that the brackets are secured to the window frame. These brackets may also be adapted to fit around the headrail such that the headrail is selectively secured to the window frame. 
     Some windows, for example double-hung windows, may be drawn inwardly into the home for cleaning purposes. For instance, U.S. Pat. No. 6,658,794, entitled “Guide Assembly for a Tilt-Out Sash Window”, teaches such a window. Furthermore, some windows comprise window screens which may be removed to promote more efficient cleaning of the windows among other things. Some of these window screens may be removed by disengaging the window screen from the window and drawing the window screen inwardly into the home. Among the drawbacks of conventional brackets is that a user may be required to remove the brackets to draw the window and/or window screen inwardly into the home. Such removal may require removal of screws from the window frame which, overtime, may cause wear of the screw holes. 
     It may be desirable to provide a bracket and/or headrail for window blinds in which the bracket and/or headrail allow for removal of the window and/or window screen without necessitating removal of the bracket. It may also be desirable to provide a bracket and/or headrail for window blinds in which the bracket and/or headrail allow for removal of the window and/or window screen without necessitating removal of any screws.

Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive. 
     I. First Bracket 
       FIGS. 1-6  show a bracket ( 100 ) operable for use in a window system as will be described in greater detail below. Bracket ( 100 ) is configured to selectively secure a headrail of blinds ( 20 ) to an interior surface ( 12 ) of the window frame ( 10 ). It should be understood that use of the term “blinds” in this specification refers to any type or method of window treatment, including but not limited to, blinds (horizontal, vertical, etc.), curtains, shades, valances, etc. It should also be understood that use of the term “headrail” in the specification refers to any structure which supports the window treatment of any configuration, including but not limited to, a headbox, a rod, etc. The bracket ( 100 ) comprises a first member ( 110 ) and a second member ( 150 ). As will be discussed in more detail below, the first member ( 110 ) and the second member ( 150 ) are pivotably coupled together. 
     The first member ( 110 ) presents a U-shaped profile having a generally flat portion ( 112 ) and a pair of curved flange members ( 114 ,  116 ) which project from opposite sides of the flat portion ( 112 ) along a portion of the flat portion ( 112 ). The pair of curved flange members ( 114 ,  116 ) are configured to fit within a channel ( 22 ) formed in an upper surface of the headrail of blinds ( 20 ) when the bracket ( 100 ) is secured to the headrail of blinds ( 20 ) as shown in  FIG. 2 . A pair of tabs ( 115 ,  117 ) extends from an end of the pair of curved flanges ( 114 ,  116 ). The pair of tabs ( 115 ,  117 ) are configured to cooperate with a lip ( 23 ) within the channel ( 22 ) of the headrail of blinds ( 20 ) such that the first member ( 110 ) may be secured at least partially within the channel ( 22 ). The first member ( 110 ) comprises a plurality of openings ( 118 ) which pass through the flat portion ( 112 ). The plurality of openings ( 118 ) are operable to receive a plurality of fasteners ( 14 ) to thereby secure the bracket ( 100 ) to the interior surface ( 12 ) of the window frame ( 10 ) such that a top surface of the flat portion ( 110 ) is disposed adjacent to the interior surface ( 12 ) of the window frame ( 10 ). The plurality of openings ( 118 ) of the present example comprises two elongated openings oriented along a common axis. It should be understood that, although the plurality of openings ( 118 ) of the present example comprises two elongated openings oriented along a common axis, any number of openings oriented in any suitable manner may be used and would be apparent to one of ordinary skill in the art according to the teachings herein. For instance, the plurality of openings ( 118 ) may comprise a single elongated opening extending along the flat portion ( 112 ). Alternatively, the plurality of openings ( 118 ) may comprise four circular openings arranged in a rectangular orientation along the flat portion ( 112 ). 
     The second member ( 150 ) includes a pair of spaced apart resilient arms ( 152 ,  154 ) and a resilient locking member ( 160 ). The resilient arms ( 152 ,  154 ) each comprise an inwardly extending tab ( 156 ,  158 ). The locking member ( 160 ) likewise comprises an inwardly extending tab ( 162 ). The tab ( 162 ) of the locking member ( 160 ) is configured to selectively engage a bottom edge of a side surface of the headrail of blinds ( 20 ) such that the second member ( 150 ) is secured to the headrail of blinds ( 20 ) as shown in  FIG. 2 . The tabs ( 156 ,  158 ) of the arms ( 152 ,  154 ) are configured to bear against the same side surface of the headrail of blinds ( 20 ). It should therefore be understood that the bracket ( 100 ) will be secured to the headrail of blinds ( 20 ) by the tabs ( 115 ,  117 ) of the first member ( 110 ) and the tabs ( 156 ,  158 ) of the second member ( 150 ). 
     The first member ( 110 ) is pivotably coupled with the second member ( 150 ). The first member ( 110 ) and the second member ( 150 ) each comprise a pair of cylindrical knuckles ( 120 ,  122 ,  164 ,  166 ). Each cylindrical knuckle of pair of the cylindrical knuckles ( 120 ,  122 ,  164 ,  166 ) comprises a circular opening that passes through the respective knuckle. The pair of cylindrical knuckles ( 120 ,  122 ) of the first member ( 110 ) and the pair of cylindrical knuckles ( 164 ,  166 ) of the second member ( 150 ) are offset relative to one another such that the pair of cylindrical knuckles ( 120 ,  122 ) interlock with the pair of cylindrical knuckles ( 164 ,  166 ) such that the pair of cylindrical knuckles ( 120 ,  122 ,  164 ,  166 ) forms one continuous cylinder as shown in  FIG. 1 . A pin ( 140 ) is disposed through each opening of the pair of cylindrical knuckles ( 120 ,  122 ,  164 ,  166 ) when arranged as a continuous cylinder such that the first member ( 110 ) and the second member ( 150 ) are operable to rotate about the pin ( 140 ). It should therefore be understood that, the first member ( 110 ) and the second member ( 150 ) are pivotably coupled together by a hinge. As will be discussed in more detail below, the bracket ( 100 ) is operable to move from an open position to a closed position or vice versa. In operation, the bracket ( 100 ) is configured to receive the headrail of blinds ( 20 ) in the open position. Non-metallic, or any suitable material, washers or separators may be positioned between the knuckles ( 120 ,  122 ,  164 ,  166 ) and may preclude direct contact between the knuckles ( 120 ,  122 ,  164 ,  166 ). Although the first member ( 110 ) and the second member ( 150 ) of the present example are pivotably coupled together by a hinge, it should be understood that first member the ( 110 ) and the second member ( 150 ) may be pivotably coupled by any appropriate method. For instance, the first member ( 110 ) and the second member ( 150 ) may be pivotably coupled together by a living hinge. 
       FIG. 4A  shows the headrail of blinds ( 20 ) secured within the bracket ( 100 ) which is secured to the interior surface ( 12 ) of the window frame ( 10 ) via the fasteners ( 14 ) passing through the plurality of openings ( 118 ). The bracket ( 100 ) is operable to receive and selectively secure the headrail of blinds ( 20 ) within the bracket ( 100 ) while in the open position.  FIGS. 3A and 4B  show the bracket ( 100 ) with the headrail of blinds ( 20 ) removed from the bracket ( 100 ). As can be seen in  FIGS. 3A and 4B , in the open position, it is impossible to remove a window screen ( 16 ) without first moving the second member ( 150 ) out of the way. It should therefore be understood that, if the bracket ( 100 ) was not capable of moving to the closed position, it would be necessary to remove the bracket ( 100 ) entirely in order to remove the window screen ( 16 ) in the manner shown. As shown in  FIGS. 3B and 4C , however, the bracket ( 100 ) of the present example is operable to move into the closed position such that the second member ( 150 ) no longer inhibits removal of the window screen ( 16 ). In this closed position, the window screen ( 16 ) may be removed without removing the bracket ( 100 ) from the window frame ( 10 ) as shown in  FIGS. 3B and 4D . 
     In some versions of the bracket ( 100 ) it may be advantageous to bias the bracket ( 100 ) toward the open position or toward the closed position. For instance, as shown in  FIG. 5 , a torsion spring ( 18 ) may be positioned between the first member ( 110 ) and the second member ( 150 ). The torsion spring ( 18 ) may be configured to urge the first member ( 110 ) and the second member ( 150 ) toward the open position or toward the closed position. It should be understood that, although the bracket ( 100 ) of the present example comprises the torsion spring ( 18 ) to bias the bracket ( 100 ) toward the open position or toward the closed position, any other biasing member may be used and would be apparent to one of ordinary skill in the art according to the teachings herein. For instance, a leaf spring may be positioned between the first member ( 110 ) and the second member ( 150 ). Furthermore, it should be understood that the biasing member may be placed in any operable position relative to the first member ( 110 ) and the second member ( 150 ) and that any number of biasing members may be used to bias the bracket ( 100 ). Finally, it should be appreciated that in versions of the bracket ( 100 ) wherein the first member ( 110 ) and the second member ( 150 ) are pivotably coupled together by a living hinge, the living hinge may be resiliently biased to urge the first member ( 110 ) and the second member ( 150 ) toward the open position or toward the closed position. 
     In some versions of the bracket ( 100 ) it may be advantageous to provide a feature which “locks” the bracket ( 100 ) in the closed position. For instance,  FIG. 5A  shows a resilient locking arm ( 180 ) extending downwardly from the curved flange member ( 114 ). A tab ( 182 ) projects inwardly from the locking arm ( 180 ) such that when the bracket ( 100 ) is moved into the closed position, the tab ( 182 ) couples about an exterior edge of the resilient arm ( 152 ), as shown in  FIG. 5B , thus “locking” the bracket ( 100 ) in the closed position. It should be understood that, the locking arm ( 180 ) may be placed in any operable position and further that any number of the locking arms ( 180 ) may be used to “lock” the bracket ( 100 ). It should also be understood that, although the bracket ( 100 ) of the present example comprises the locking arm ( 180 ) to “lock” the bracket ( 100 ) in the closed position, any other locking feature may be used and would be apparent to one of ordinary skill in the art according to the teachings herein. For instance,  FIG. 6  shows a set of hook and loop pads ( 190 ,  192 ) positioned on a bottom surface of the flat portion ( 112 ) of the first member ( 110 ) and an interior surface of the second member ( 150 ). The pads ( 190 ,  192 ) are oriented such that the pads ( 190 ,  192 ) align when the bracket ( 100 ) is in the closed position thereby “locking” the bracket ( 100 ) in the closed position. 
     It should be appreciated that any appropriate number of the brackets ( 100 ) may be used to secure the headrail of blinds ( 20 ) to the window frame ( 10 ). It should further be appreciated that although the bracket ( 100 ) is discussed in the context of use with the headrail of blinds ( 20 ) and the window frame ( 10 ), the bracket ( 100 ) may be used for any purpose and would be apparent to one of ordinary skill in the art according to the teachings herein. 
     II. Second Bracket 
       FIG. 7  shows an alternative bracket ( 200 ) operable for use in a window system as will be described in greater detail below. Bracket ( 200 ) is configured to selectively secure an alternative headrail of blinds ( 40 ) to the interior surface ( 12 ) of the window frame ( 10 ). The bracket ( 200 ) comprises a curved member ( 210 ) having a first flat portion ( 212 ), a second flat portion ( 214 ), and a curved portion ( 213 ). The curved portion ( 213 ) is positioned between the first flat portion ( 212 ) and the second flat portion ( 214 ). The second flat portion ( 214 ) comprises a plurality of openings ( 216 ). The plurality of openings ( 216 ) are operable to receive a plurality of fasteners ( 54 ) to thereby secure the bracket ( 200 ) to the interior surface ( 12 ) of the window frame ( 10 ) such that a top surface of the second flat portion ( 214 ) is disposed adjacent to the interior surface ( 12 ) of the window frame ( 10 ). The plurality of openings ( 216 ) of the present example comprises two elongated openings oriented along a common axis. It should be understood that, although the plurality of openings ( 216 ) of the present example comprises two elongated openings oriented along a common axis, any number of openings oriented in any manner may be used and would be apparent to one of ordinary skill in the art according to the teachings herein. For instance, the plurality of openings ( 216 ) may comprise a single elongated opening extending along the second flat portion ( 214 ). Alternatively, the plurality of openings ( 216 ) may comprise a pair of circular openings arranged along a common axis. 
     As best seen in  FIGS. 9A-9B , with the second flat portion ( 214 ) pressed flush against the interior surface ( 12 ) of the window frame ( 10 ), the curved portion ( 213 ) is configured such that the first flat portion ( 212 ) extends generally parallel to the interior surface ( 12 ) of the window frame ( 10 ) thus defining a gap between the first flat portion ( 212 ) and the interior surface ( 12 ). Alternatively, the first flat portion ( 212 ) may extend at a slight upward angle from the curved portion ( 213 ) so as to urge the headrail of blinds ( 40 ) upward against an interior surface of the window frame ( 10 ), thus pinching the headrail of blinds ( 40 ) between the first flat portion ( 212 ) and the interior surface of the window frame ( 10 ) as will be understood from the discussion below. As shown in  FIG. 8 , the headrail of blinds ( 40 ) comprises a plurality of slots ( 42 ) extending at least partially through the headrail of blinds ( 40 ) from an exterior surface of headrail of blinds ( 40 ). The plurality of slots ( 42 ) is positioned a distance from a top surface of headrail of blinds ( 40 ) substantially similar to the gap between the first flat portion ( 212 ) and the interior surface ( 12 ). Each slot ( 42 ) of the plurality of slots ( 42 ) is configured to slidably receive the first flat portion ( 212 ) of each bracket ( 200 ). With the bracket ( 200 ) slidably disposed within the slot ( 42 ), the headrail of blinds ( 40 ) is secured to the window frame ( 10 ). A flat member ( 218 ) projects from the second flat portion ( 214 ) of the curved member ( 210 ) and is configured to bear against a portion of the window frame ( 10 ) to, among other things, add to the rigidity and strength of the bracket ( 200 ). The flat member ( 218 ) is sized such that the flat member ( 218 ) does not inhibit removal of the window screen ( 16 ). 
     As shown in  FIG. 9A , to remove the window screen ( 16 ), the headrail of blinds ( 40 ) must first be removed from the bracket ( 200 ). Once the headrail of blinds ( 40 ) is removed, from the bracket ( 200 ), the window screen ( 16 ) may be removed without requiring removal of the bracket ( 200 ) as shown in  FIG. 9B . 
     The first flat portion ( 212 ) of the bracket ( 200 ) may comprise a locking feature configured to selectively secure the bracket ( 200 ) within the slot ( 42 ). The slot ( 42 ) may comprise a mating locking feature to engage the locking feature of the bracket ( 200 ). It should be understood that, the plurality of slots ( 42 ) may extend partially or completely through the headrail of blinds ( 40 ) such that the first flat portion ( 212 ) of the bracket ( 200 ) may extend partially or completely through the headrail of blinds ( 40 ). It should also be understood that, the first flat portion ( 212 ) may be angled upward to thereby drive the headrail of blinds ( 40 ) upward into the interior surface ( 12 ) of the window frame ( 10 ), thus pinching headrail between first the flat portion ( 212 ) and the interior surface ( 12 ). 
     It should be appreciated that any appropriate number of the brackets ( 200 ) may be used to secure the headrail of blinds ( 40 ) to the window frame ( 10 ). It should further be appreciated that although the bracket ( 200 ) is discussed in the context of use with the headrail of blinds ( 40 ) and the window frame ( 10 ), the bracket ( 200 ) may be used for any purpose and would be apparent to one of ordinary skill in the art according to the teachings herein. 
     III. Third Bracket 
       FIG. 10  shows another alternative bracket ( 300 ) operable for use in a window system as will be described in greater detail below. Bracket ( 300 ) is configured to selectively secure the headrail of blinds ( 40 ) to the interior surface ( 12 ) of the window frame ( 10 ). The bracket ( 300 ) comprises a first flat member ( 310 ) and a second flat member ( 320 ) each extending from a third flat member ( 330 ) and thus defining a gap there between. As best seen in  FIG. 11 , the first flat member ( 310 ) extends perpendicularly from the third flat member ( 330 ) whereas the second flat member ( 320 ) extends at a slight upward angle from the third flat member ( 330 ). As will be discussed in more detail below, this upward angle of the second flat member ( 320 ) will drive the headrail of blinds ( 40 ) upward into the first flat member ( 310 ), thus pinching the headrail of blinds ( 40 ) between the first flat member ( 310 ) and the second flat member ( 320 ). 
     The first flat member ( 310 ) comprises a plurality of openings ( 312 ). The plurality of openings ( 312 ) are operable to receive a plurality of fasteners ( 64 ) to thereby secure the bracket ( 300 ) to the interior surface ( 12 ) of the window frame ( 10 ) such that a top surface of the first flat member ( 310 ) is pressed flush against the interior surface ( 12 ) of the window frame ( 10 ). The plurality of openings ( 312 ) of the present example comprises two circular openings oriented along a common axis. It should be understood that, although the plurality of openings ( 312 ) of the present example comprises two circular openings oriented along a common axis, any number of openings oriented in any manner may be used and would be apparent to one of ordinary skill in the art according to the teachings herein. 
     The second flat member ( 320 ) also comprises a plurality of openings ( 322 ) aligned with the plurality of openings ( 312 ) of the first flat member ( 310 ). The plurality of openings ( 322 ) are operable to allow the plurality of fasteners ( 64 ) to pass completely through to thereby engage the first flat member ( 310 ). The plurality of openings ( 322 ) of the present example comprises two rounded-square openings oriented along a common axis. It should be understood that, although the plurality of openings ( 322 ) of the present example comprises two rounded-square openings oriented along a common axis, any number of openings oriented in any manner may be used and would be apparent to one of ordinary skill in the art according to the teachings herein. 
     As discussed above, the headrail of blinds ( 40 ) comprises the plurality of slots ( 42 ) extending inwardly from an exterior surface of the headrail of blinds ( 40 ). The plurality of slots ( 42 ) is positioned a distance from a top surface of the headrail of blinds ( 40 ) substantially similar to the gap between the first flat member ( 310 ) and the second flat member ( 320 ). Each slot ( 42 ) of the plurality of slots ( 42 ) is configured to slidably receive the second flat member ( 320 ) of each bracket ( 300 ). With the bracket ( 300 ) slidably disposed within the slot ( 42 ), the headrail of blinds ( 40 ) is pinched between the first flat member ( 310 ) and the second member ( 320 ) and is thereby selectively secured to the window frame ( 10 ). The third flat member ( 330 ) is configured to be disposed against a portion of the window frame ( 10 ) to, among other things, add to the rigidity and strength of the bracket ( 300 ). The third flat member ( 330 ) is sized such that neither the third flat member ( 330 ) nor the second flat member ( 320 ) inhibits removal of the window screen ( 16 ). 
     As shown in  FIG. 12A , to remove the window screen ( 16 ), the headrail of blinds ( 40 ) must first be removed from the bracket ( 300 ). Once the headrail of blinds ( 40 ) is removed, from the bracket ( 300 ), the window screen ( 16 ) may be removed without requiring removal of the bracket ( 300 ) as shown in  FIG. 12B . 
     The second flat member ( 320 ) of the bracket ( 300 ) may comprise a locking feature configured to selectively secure the bracket ( 300 ) within the slot ( 42 ). The slot ( 42 ) may comprise a mating locking feature to engage the locking feature of the bracket ( 300 ). It should be understood that, the plurality of slots ( 42 ) may extend partially or completely through the headrail of blinds ( 40 ) such that the second flat member ( 320 ) of the bracket ( 300 ) may extend partially or completely through the headrail of blinds ( 40 ). 
     It should be appreciated that any appropriate number of the brackets ( 300 ) may be used to secure the headrail of blinds ( 40 ) to the window frame ( 10 ). It should further be appreciated that although the bracket ( 300 ) is discussed in the context of use with a the headrail of blinds ( 40 ) and the window frame ( 10 ), the bracket ( 300 ) may be used for any purpose and would be apparent to one of ordinary skill in the art according to the teachings herein. 
     IV. First Rotatable Fastener 
     It may be necessary to allow a user to selectively remove a bracket from a window frame ( 10 ) without requiring removal of the fastener(s) securing the bracket to the window frame ( 10 ). It may further be necessary to allow such selective removal of a bracket while the bracket is attached to the headrail of blinds ( 20 ). (It should be understood that the headrail of blinds ( 20 ) have been omitted from  FIGS. 18A and 18B  for the sake of clarity.)  FIGS. 13-18B  show a fastener ( 400 ) operable for use in a window system as will be described in greater detail below. Fastener ( 400 ) is operable to allow a user to selectively remove and/or secure a bracket ( 450 ), whether secured to the headrail of blinds ( 20 ), to the window frame ( 10 ) without requiring removal of a screw ( 440 ), which secures the bracket ( 450 ) to the window frame ( 10 ). 
     As best seen in  FIGS. 13-15 , the fastener ( 400 ) comprises a cylindrical body ( 410 ), a lever arm ( 420 ), and a locking member ( 430 ). The lever arm ( 420 ) and the locking member ( 430 ) extend form the cylindrical body ( 410 ). As best seen in  FIG. 14 , the lever arm ( 420 ) extends from the cylindrical body ( 410 ) along a first axis (A 1 ), and the locking member ( 430 ) extends from the cylindrical body ( 410 ) along a second axis (A 2 ). The first axis (A 1 ) and the second axis (A 2 ) are oriented such that the first axis (A 1 ) and the second axis (A 2 ) define an angle (α) between them. For instance, the angle (α) may be 45°; it should be understood however, that any appropriate angle may be used. A cylindrical opening ( 412 ) passes completely through the cylindrical body ( 410 ) along a third axis (A 3 ). As will be discussed in more detail below, the screw ( 440 ) passes through the opening ( 412 ) to rotatably secure the fastener ( 400 ) to the interior surface ( 12 ) of the window frame ( 10 ). The lever arm ( 420 ) includes a paddle ( 422 ) positioned at an end of the lever arm ( 420 ) opposite of the cylindrical body ( 410 ). As will be discussed in more detail below, a user engages the paddle ( 422 ) of the lever arm ( 420 ) to thereby rotate the fastener ( 400 ) about the third axis (A 3 ) from an unlocked position to a locked position. 
     As shown in  FIGS. 16A-17B , the fastener ( 400 ) is secured to the interior surface ( 12 ) of the window frame ( 10 ) by the screw ( 440 ). A washer ( 442 ) is positioned between a head of the screw ( 440 ) and the cylindrical body ( 410 ) of the fastener ( 400 ) to provide for rotation of the fastener ( 400 ). With the fastener ( 400 ) secured to the interior surface ( 12 ) of the window frame ( 10 ), the lever arm ( 420 ) extends beyond the window frame ( 10 ) such that a user may easily engage the paddle ( 422 ) of the lever arm ( 420 ) to thereby rotate the fastener ( 400 ).  FIGS. 16A and 17A , show the fastener ( 400 ) in the unlocked position. As best seen in  FIG. 17A , in the unlocked positioned, the locking member ( 430 ) is oriented substantially perpendicular to the window frame ( 10 ). As will be discussed in more detail below, in the unlocked position, the fastener ( 400 ) is capable of receiving the bracket ( 450 ).  FIGS. 16B and 17B , show the fastener ( 400 ) having been rotated into the locked position by rotation of the lever arm ( 420 ). As best seen in  FIG. 17B , in the locked positioned, the locking member ( 430 ) is oriented substantially parallel to the window frame ( 10 ). As will be discussed in more detail below, in the locked position, fastener ( 400 ) is capable of locking the bracket ( 450 ) adjacent to the interior surface of the window frame ( 10 ). 
       FIG. 18A  shows the fastener ( 400 ) in the unlocked position. The bracket ( 450 ) of the present example is configured to operate substantially similar to the bracket ( 100 ) discussed above except for the differences discussed below. For instance, the bracket ( 450 ) is configured to selectively secure the headrail of blinds ( 20 ) to the interior surface ( 12 ) of the window frame ( 10 ). The bracket ( 450 ) is configured such that it is not capable of bending. The bracket ( 450 ) includes an elongate opening ( 452 ) which passes through a flat portion ( 454 ) of bracket ( 450 ). The locking member ( 430 ) is configured to pass through the elongate opening ( 452 ) such that the bracket may be disposed adjacent to the interior surface ( 12 ) of the window frame ( 10 ). When the bracket ( 450 ) is disposed adjacent to the interior surface ( 12 ) of the window frame ( 10 ), the cylindrical body ( 410 ) is rotatably positioned within the elongate opening ( 452 ). Furthermore, when the bracket ( 450 ) is disposed adjacent to the interior surface ( 12 ) of the window frame ( 10 ), the lever arm ( 420 ) is positioned between the bracket ( 450 ) and the interior surface ( 12 ) of the window frame ( 10 ). Thus, it should be understood that, when the bracket ( 450 ) is disposed adjacent to the interior surface ( 12 ) of the window frame ( 10 ), the lever arm ( 420 ) is positioned above the flat portion ( 454 ) of bracket ( 450 ), the locking member ( 430 ) is positioned below the flat portion ( 454 ) of bracket ( 450 ), and a portion of the cylindrical body ( 410 ) is positioned within the elongate opening ( 452 ). As best seen in  FIG. 15 , a vertical space ( 414 ) is defined between the lever arm ( 420 ) and the locking member ( 430 ). It should be understood that this vertical space ( 414 ) is configured such that the vertical space ( 414 ) measures substantially similar to a height of the flat potion ( 454 ) of the bracket ( 450 ).  FIG. 18B  shows the fastener ( 400 ) rotated into the locked position by rotation of the lever arm ( 420 ). In the locked position, the locking member ( 430 ) secures the bracket ( 450 ) to the interior surface ( 12 ) of the window frame ( 10 ). 
     It should be understood that although the headrail of blinds ( 20 ) of the present example has been omitted for the sake of clarity, bracket ( 450 ) may be secured and/or removed from the window frame ( 10 ) by fastener ( 400 ) while the bracket ( 450 ) is secured to the headrail of blinds ( 20 ). It should further be understood that, with bracket ( 450 ) secured to the headrail of blinds ( 20 ), the locking member ( 430 ) of fastener would rotate within the channel ( 22 ) formed in the upper surface of the headrail of blinds ( 20 ) such that the fastener ( 400 ) may be rotated from the locked position to the unlocked position and vice versa. 
     It should further be understood that, although the fastener ( 400 ) is discussed as being configured to selectively secure the bracket ( 450 ) to the interior surface ( 12 ) of the window frame ( 10 ), the fastener ( 400 ) may be used to selectively secure any of the brackets ( 100 ,  200 ,  300 ) discussed above to the interior surface ( 12 ) of the window frame ( 10 ). Furthermore, it should be understood that the headrail of blinds ( 20 ) may include integral slots such that the headrail of blinds ( 20 ) may be secured to the window frame ( 10 ) via the fastener ( 400 ) without the need for the bracket ( 450 ) in the manner described above. 
     V. Second Rotatable Fastener 
       FIGS. 19-21  show an alternative fastener ( 500 ) operable for use in a window system as will be described in greater detail below. Fastener ( 500 ) is operable to allow a user to selectively remove and/or secure the bracket ( 450 ), whether secured to the headrail of blinds ( 20 ), to the window frame ( 10 ) without requiring removal of a screw (not shown), which secures the bracket to the window frame ( 10 ). Fastener ( 500 ) is configured to operate substantially similar to fastener ( 400 ) discussed above except for the differences discussed below. In particular, fastener ( 500 ) is configured to rotate between a locked position and an unlocked position to thereby secure the bracket ( 450 ) to the interior surface ( 12 ) of the window frame ( 10 ). 
     The fastener ( 500 ) comprises a cylindrical body ( 510 ), a lever arm ( 520 ), and a locking member ( 530 ). The lever arm ( 520 ) and the locking member ( 530 ) extend form the cylindrical body ( 510 ). As best seen in  FIG. 20 , the lever arm ( 520 ) extends from the cylindrical body ( 510 ) along a first axis (A 4 ), and the locking member ( 530 ) extends from the cylindrical body ( 510 ) along a second axis (A 5 ). The first axis (A 4 ) and the second axis (A 2 ) are oriented such that the first axis (A 4 ) and the second axis (A 5 ) define an angle (α) between them. For instance, the angle (α) may be 45°; it should be understood however, that any appropriate angle may be used. A cylindrical opening ( 512 ) passes completely through the cylindrical body ( 510 ) along a third axis (A 6 ). A screw passes through the opening ( 512 ) to rotatably secure the fastener ( 500 ) to the interior surface ( 12 ) of the window frame ( 10 ). The lever arm ( 520 ) includes a paddle ( 522 ) positioned at an end of the lever arm ( 520 ) opposite of the cylindrical body ( 510 ). A user engages the paddle ( 522 ) of the lever arm ( 520 ) to thereby rotate the fastener ( 500 ) about the third axis (A 6 ) from an unlocked position to a locked position. 
     The locking member ( 530 ) includes a ramp ( 532 ) positioned at an end of the locking member ( 530 ) opposite of the cylindrical body ( 510 ). The ramp ( 532 ) is oriented such that as the fastener ( 500 ) is rotated toward the locked position, the ramp ( 532 ) will increasingly apply force to the bottom surface of the flat portion ( 454 ) of the bracket ( 450 ) to thereby increasingly compress the flat portion ( 454 ) of the bracket ( 450 ). It should be understood that, locking member ( 530 ) may be flexible such that as more force is applied to the bottom surface of the flat portion ( 454 ) of the bracket ( 450 ), the locking member ( 530 ) will flex. 
     It should be understood that, although the fastener ( 500 ) is discussed as being configured to selectively secure the bracket ( 450 ) to the interior surface ( 12 ) of the window frame ( 10 ), the fastener ( 500 ) may be used to selectively secure any of the brackets ( 100 ,  200 ,  300 ) discussed above to the interior surface ( 12 ) of the window frame ( 10 ). Furthermore, it should be understood that the headrail of blinds ( 20 ) may include integral slots such that the headrail of blinds ( 20 ) may be secured to the window frame ( 10 ) via the fastener ( 500 ) without the need for the bracket ( 450 ) in the manner described above.
