摘要:
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 screen system for use with a sliding panel of a window or door is used to screen an opening as the sliding panel or door is opened. The screen is attached to the edge of the sliding panel adjacent the opening, and is wound onto a spindle. The spindle is rotatably mounted adjacent the screen opening around which the screen is wound so that the screen can be unwound from or wound onto the spindle. A cord is connected between the sliding panel and the spindle pulley via an idler pulley. In this arrangement the spindle is caused to rotate so as to wind the screen back onto the spindle as the sliding panel is slid towards the closed position. Whilst the screen is wound off the spindle, the cord is wound onto the spindle pulley and vice versa. As the A tension adjustment arrangement can also be provided that is configured to adjust the tension in the cable as the screen is wound and unwound from the spindle due to the change in diameter of the cord around the spindle pulley.
摘要:
A retractable and extendable covering device (1) for architectural openings, which includes first and second substantially parallel posts (3, 5), a retractable and extendable substantially rectangular screen member (7), and a first flexible guide member (9; 109). The first flexible guide member (9; 109) is deflected into one of the first and second posts (3, 5) and slidably receivable therein. Each of the parallel posts (3, 5) has a hollow interior (19, 23), and at least one of the first and second posts being movable toward and away with respect to the other. The retractable and extendable screen member (7) has first and second pairs of opposite parallel edges and is mounted between the first and second parallel posts (3, 5) at its first pair of parallel edges. The first flexible guide member (9; 109) extends along one edge of the second pair of parallel edges of the screen member (7) and between the first and second posts (3, 5) for retaining the one edge of the screen member (7). The first and second parallel posts (3, 5) each include a base profile part (69; 169) and an auxiliary profile part (71; 171) defining the hollow interior (19, 23) therebetween for slidably receiving the first flexible guide member (9). Optionally the auxiliary profile part (71; 171) is mountable to the base profile part (69; 169) in a selected one of two different positions in which it is connectable to the base profile.
摘要:
In a folding screen device pulled in the lateral direction, the widthwise dimension limit of the screen device in the opening and closing direction of the screen is eliminated. A plurality of screen units include movable vertical frame members attached to both ends of a screen expandable in an accordion manner. The vertical frame members are slidable along a lateral frame member of a building opening. Screen guides in the screen units move out and into the interior of the vertical frame member through upper and lower ends thereof in a bent state, and are led along upper and lower ends of the screen in an extended state. A parallel movement mechanism causes the vertical frame members to move in parallel during opening and closing of the screen. The screen units can be arranged in parallel in the building opening by connecting adjacent vertical frame members of the screen units.

An adjustable window grill comprises a first frame member comprising two arms and a base and a second frame member comprising a base and two hollow arms telescopically slidable over the arms of the first frame member. The first frame member has a mesh attached, which extends beyond it and which is received in slots in the inside walls of the arms and the inside and outside walls of the base of the second frame member. A plush fabric is attached to the outer surface of the arms of the first frame.
