Abstract
A rolling window screen assembly for use with a window assembly. The screen assembly is deployable in at least three positions. The first engagement position exists wherein the flexible screen may be extended over the entire window. The second engagement position exists wherein the flexible screen is releasably engaged to a sash to enable the flexible screen o be deployed dynamically according to the position of the sash. Finally, the flexible screen may be disengaged from the window assembly and retracted to expose substantially all of the window opening. A pull-cord apparatus having a pull-down non-elastic cord interfacing with an elastic take-up cord may be utilized for manipulating the flexible screen.
Claims15
A rolling window screen apparatus comprising:
- a roller rotatably attachable to a window assembly, wherein said window assembly includes a window frame having top, bottom, and opposite sides which together define a window area and having a sash slideably retained within the window frame for being selectively positioned for defining a window opening within the window frame;
- and
- a flexible screen carried by the roller, wherein the flexible screen may be deployed in at least three deployment states, and wherein the at least three deployment states comprise:
- a first deployment state wherein the flexible screen is releasably engaged to the window frame to enable the flexible screen to be deployed statically to cover at least a portion of the window opening;
- a second deployment state wherein the flexible screen is releasably engaged to the sash to enable the flexible screen to be deployed dynamically according to the position of the sash;
- and
- a third deployment state wherein the flexible screen is disengaged from the window assembly to enable the retraction of the flexible screen onto the roller to expose substantially all of the window opening.
A pull-cord apparatus for deploying a window treatment, the pull-cord apparatus comprising:
- a pull-down non-elastic cord having a general length attached to a window treatment having a bottom and a bottom edge, wherein the window treatment is rollable into an undeployed position and unrollable into a deployed position for at least partially covering a window, wherein the pull-down non-elastic cord attaches substantially near the center of the bottom;
- an elastic take-up cord of a general length carried by the bottom edge of the window treatment;
- an interface for interfacing the pull-down non-elastic cord and the elastic take-up cord at a position below the bottom of the window treatment enabling the elastic take-up cord to influence the pull-down non-elastic cord;
- a stiffening member carried by the bottom of the window treatment intermediary to the pull-down non-elastic cord and the elastic take-up cord;
- wherein the pull-down non-elastic cord has a first retracted position wherein the elastic take-up cord influences a portion of the pull-down non-elastic cord to be generally horizontal to the bottom of the window treatment, the pull-down non-elastic cord having a sufficient length such that a force transmitting portion of the pull-down non-elastic cord depends downward from the interface providing a surface for grabbing when in the first retracted position;
- and
- wherein the pull-down non-elastic cord has a second position when a downward force is applied to the force transmitting portion of the pull-down non-elastic cord such that the pull-down non-elastic cord is generally normal to the bottom of the window treatment enabling the downward force to be transmitted to the window treatment facilitating the downward deployment of the window treatment.
A rolling window screen apparatus comprising:
- a roller rotatably attachable to a window assembly, wherein said window assembly includes a window frame having top, bottom, and opposite sides which together define a window area and having a sash slideably retained within the window frame for being selectively positioned for defining a window opening within the window frame;
- and
- a flexible screen carried by the roller and having an edge, wherein the flexible screen is deployable in at least three deployment states, and wherein the at least three deployment states comprise:
- a first deployment state wherein the flexible screen is releasably engaged to the window frame to enable the flexible screen to be deployed statically to cover at least a portion of the window opening;
- a second deployment state wherein the flexible screen is releasably engaged to the sash to enable the flexible screen to be deployed dynamically according to the position of the sash;
- and
- a third deployment state wherein the flexible screen is disengaged from the window assembly to enable the retraction of the flexible screen onto the roller to expose substantially all of the window opening;
- and
- a pull-cord apparatus for deploying the flexible screen, the pull-cord apparatus comprising:
- a pull-down non-elastic cord having a general length connected to the edge of the flexible screen;
- an elastic take-up cord of a general length carried by the edge of the flexible screen;
- an interface for interfacing the pull-down non-elastic cord and the elastic take-up cord at a position below the edge of the flexible screen enabling the elastic take-up cord to influence the pull-down non-elastic cord;
- wherein the pull-down non-elastic cord has a first retracted position wherein the elastic take-up cord influences a portion of the pull-down non-elastic cord to be generally horizontal to the edge of the flexible screen, the pull-down non-elastic cord having a sufficient length such that a force transmitting portion of the pull-down non-elastic cord depends downward from the interface providing a surface for grabbing when in the first retracted position;
- and
- wherein the pull-down non-elastic cord has a second position when a downward force is applied to the force transmitting portion of the pull-down non-elastic cord such that the pull-down non-elastic cord is generally normal to the edge of the flexible screen enabling the downward force to be transmitted to the flexible screen facilitating the downward deployment of the flexible screen.
