A window frame assembly has a built-in foldable screen, having a body, the body having at least a first frame part and a second frame part; the first frame part has at least a first end surface and a second end surface; the second end surface is fixedly connected to the second frame part; the first end surface is provided with a protruded guiding convex part; the guiding convex part is provided with a line receiving groove; and two sides of the line receiving groove are respectively provided with a concave part. The above structure has the benefits of enabling the guiding convex part located on the transverse frame in the foldable screen module to be re-assembled on the structure of the window frame assembly, thus reducing the number of foldable screen module components, and also improving the convenience of assembling the foldable screen module in the window.

A wire drawing tightness controller for an easily detachable and foldable screen, comprising: a connecting member, a wire drawing control device, a first connecting unit and a second connecting unit, wherein the connecting member is provided on a window frame, the wire drawing control device is provided with at least a control unit, and the first connecting unit and the second connecting unit are arranged between the connecting member and the wire drawing control device. By means of the arrangement of the first connecting unit and the second connecting unit, the wire drawing control device can be conveniently connected to the connecting member, and can also be easily separated from the connecting member, thereby enhancing the convenience of assembling a foldable screen.

A retractable screen structure to cover opening of windows. The structure has a first housing member with a coiled screen mesh therewithin. A second elongated housing member is engaged with an end of the screen mesh extending out of the first housing member. The second housing member has a releasable locking element and is parallel to the first housing member. A cooperative releasable locking element positioned on the window or window frame, is configured to cooperate with the releasable locking element of the second housing member to effect a releasable locking h, The coiled screen mesh substantially covers the opening when uncoiled and is connected to a retracting/extending mechanism contained within the first housing which allows the end of the screen mesh be drawn through an opening in the first housing and uncoiled to substantially cover the opening and to retract the screen mesh when desired.

Retractable screen assemblies having cores with tension sections and methods are described herein. The retractable screen assemblies include features configured to promote parallel (or nearly parallel) extension and retraction in a retractable screen assembly in which the edges of the screen material are retained during extension and retraction.

Disclosed is an adjustable retractable screen door including a retractable screen door, wherein a screen housing is sleeved with an end cap, the end cap includes a housing and a guide leg, the end cap is connected with a screen channel through the guide leg, and the screen channel is provided with an end cap connection channel and a handle slide channel. This mounting accessory is used for compatibly mounting the above-mentioned adjustable retractable screen door and includes an upper mounting adapter and a lower mounting adapter. The upper mounting adapter includes an upper mounting block and an adjustment block which cooperates with the upper mounting block and a connector, the upper mounting block includes a screw boss, an adjustment screw and a locator guide, and the adjustment block includes a threaded hole and a guide bump.

A retractable screen system includes a screen that is movable, via rotational movement of a motor to raise and lower the screen in a vertical manner. The screen can start at the motor and retract downward. To aid in the controlled movement of the screen, a track system includes an outer rail housing an inner channel. The inner channel includes a channel for receiving a portion of the screen, such as a keder. The keder channel controls the movement of the keder and screen. At times, the outer rail or inner channel may not be oriented as desired, and therefore, the inner channel includes the ability to float or move in a direction transversely to the direction of movement of the screen. Plastic clips can urge the inner channel to a position but can be manipulated to allow for some float of the inner channel.

A looped tension member is disposed in a Z-axis direction, and an inside of a slidable frame is divided into first and second storage portions for respectively storing first and second guides at opposite sides in the X-axis direction. The first and second storage portions allow the tension member to pass, and direction changing members on which the tension member is suspended are provided in opposite end portions of the slidable frame in the Z-axis direction. One of the direction changing members is disposed through a supporting member at one end portion in the Z-axis direction of the first storage portion, relieving pieces extending in the Z-axis direction and opposing each other in a Y-axis direction are provided with the supporting member, and each of the relieving pieces contacts needle parts of screen retaining members and causes the needle parts to bend away from the supporting member.

A screen device includes a cylinder body, a movable frame and two first frame materials, wherein the cylinder body and the movable frame are disposed between the two first frame materials, and a rolling bar is disposed in the cylinder body; a screen is disposed between the rolling bar and the movable frame, and at least one rotating member is disposed in the cylinder body; at least one pull line penetrates the movable frame, and at least one end of the pull line penetrates the first frame material to extend into the cylinder body, and is then combined to the rotating member; the rotating member is disposed on a side portion of the cylinder body, and therefore, the rotating member can be adjusted and controlled only by using a tool on the side portion of the cylinder body, so as to adjust and control the tightness of the pull line when needed. The process thereof is completely free from blockages caused by any component, and adjustment and control is really convenient.

A connector is connected to a second guide unit positioned at one end in a Z-axis direction of a second guide stored in a storage portion of a slidable frame, is longitudinal in an X-axis direction and has a female part and a male part that is fixable to and separate from the female part. The female part has a pair of connecting pieces having respective third openings into which second pins of a second guide unit are respectively fitted, a fourth opening at one end portion in the Z-axis direction and which is open in the X-axis direction, and a hollow receiving portion extending in the Z-axis direction. The male part is storable in the receiving portion, and opposite ends of a tension member are fixed to the male part. The male part includes a fixing piece which has a fifth opening capable of communicating with the fourth opening.

Retractable and extendable covering device for an architectural opening, comprising: first and second substantially parallel, in particular vertical, posts, each having a hollow interior, and at least one of the first and second posts being movable toward and away with respect to the other of the first and second posts; a retractable and extendable substantially rectangular screen member having first and second pairs of opposite parallel edges and being mounted between the first and second parallel posts at the first pair of parallel edges; a first flexible guide member coupled to the covering member and arranged to be at least partially moved into the hollow interior of the first post;

wherein the covering device further comprises a flexible covering member covering at least part of the first flexible guide member.
