In addition, an assembly of such a guide device (1) with a door of frame profile (21), a screen device (2) comprising such a guide device (1), an assembly of such a screen device (2) and a door or frame profile (21), and a method for mounting such a guide device (1) on a door or frame profile (21).

A screen system for use with a sliding panel of a window or door 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 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. The spindle is caused to rotate to wind the screen onto the spindle as the sliding panel is slid towards the closed position. While the screen is wound off the spindle, the cord is wound onto the spindle pulley and vice versa. A tension adjustment arrangement is provided for adjusting the tension in the cable as the screen is wound and unwound from the spindle.

There is provided a screen guide that engages a support rail or is detachable from the support rail at an intermediate position on the support rail. The support rail supports the screen guide and includes first and second engagement edges, and the screen guide is formed by connecting a plurality of guide pieces to one another in series. Each of the guide pieces includes a piece body that engages an end portion of a screen and an engagement member that includes first and second engagement portions that engage the first and second engagement edges of the support rail, respectively. Each of the engagement members is coupled to the corresponding piece body such that the engagement member is capable of being displaced to a first position at which the first and second engagement portions engage the first and second engagement edges, respectively, and to a second, detached position.

A screen assembly including a flexible screen having a first edge and a second edge, a substantially vertical supporting member about which the screen can be wound/unwound and to which the first edge of the screen is mounted, a drum associated with at least one end of the supporting member, at least one line member that can be wound onto and off the drum, and a first removable clip. The first removable clip including: a body portion defining an opening for receiving a portion of a supporting member and drum assembly, and an upwardly extending portion, wherein the upwardly extending portion is configured to hold the at least one line member relative to an external surface of the drum during transportation of the screen assembly or prior to operation of the screen assembly.

A screen device (1), comprising a screen roller (2), a screen (3) which can be rolled up and unrolled hereon, an end lath (4), which is fitted to an opposite side of the screen (3), and a tensioning system (8) to tension the screen (3) in the roll-up and unrolling direction, the tensioning system comprising on each lateral side of the screen (3) a band wheel (5) next to the screen roller (2), a tensioning cord (6), which can be rolled up and unrolled hereon and which, at its end away from the band wheel (5), is fastened to the end lath (4), away from the screen roller (2) a reversing wheel (7), via which the tensioning cord (6) is turned, and a spring sub-system (18), which comprises at least one spring element (9) for keeping the respective tensioning cord (6) under tension, wherein at least one of the spring sub-systems (18) comprises adjustors (10, 11, 14, 13, 16) for adjusting the spring force of the spring element (9).

A flexible-panel door is mountable to a door frame. Opposite ends of a top rail are slidably engaged with end caps respectively affixed to ends of first and second side rails, and opposite ends of a bottom rail are likewise slidably engaged with end caps respectively affixed to opposite ends of the first and second side rails. With the first side rail secured to or in contact with the first side of the door frame, the second side rail is moved into contact with the second side of the door frame such that the top and bottom rails slide relative to at least one of their respective end caps such that each combination extends across the width of the door frame. A flexible panel carried by one of the first and second side rails is extendable toward the other of the first and second side rails.

This electric screen device is provided with an electric motor that causes slidable screen mounting frame part(s) to automatically slide. Torque generated by rotation of a rotation shaft of the electric motor is transmitted to a tension member that is provided inside the screen mounting frame parts, that connects screen guiding frame parts to each other at free ends thereof, and that forms a loop. The tension member moves in a state of being hung around the folded portions which apply tension to the tension member. The slidable screen mounting frame part(s) automatically slide in association with movement of the tension member. Thus, the screen automatically opens and closes.

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 retractable bathroom door includes a fixed frame (1), a mobile frame (2), a first parallel pull string (3) and a foldable portion (4). The mobile frame (2) is perpendicular to the upper frame portion of the fixed frame (1) and horizontally moves in a frame range of the fixed frame (1). A frame portion at one side of the mobile frame (2) has a first hollow structure (13). A first upper pulley (5) and a first lower pulley (6) are respectively disposed at a top end and a bottom end of the first hollow structure (13). The first parallel pull string (3) has two ends which are connected and wound around the first upper pulley (5) and the first lower pulley (6) in a crossover manner. An upper rail and a lower rail are respectively disposed on the upper frame portion and the lower frame portion of the fixed frame (1). An upper rack (9) and a lower rack (10) are respectively disposed on the upper rail and the lower rail. Two ends of the upper rack (9) and the lower rack (10) respectively enter the first hollow structure (13) from a first upper opening (7) and a first lower opening (8) of the first hollow structure (13), and are connected with the first parallel pull string (3). A length of the upper rack (9) disposed on the upper rail is as same as a length of the lower rack (10) disposed on the lower rail. The foldable portion (4) is disposed between two mobile frame portions of the mobile frame. The retractable bathroom door is adapted for small space installation, has strong adaptability and stable moving.

A retractable, flexible-panel door is mountable to a door frame attached to a building and includes a first side rail, a second side rail, a top rail mountable to and between the first and second side rails, and a bottom rail mountable to and between the first and second side rails. A flexible panel extends between the top and bottom rails, and at least one biasing member draws the flexible panel toward one of the first and second side rails. The top and bottom rails are each axially expandable and reducible in length to accommodate mounting of the retractable, flexible panel door to door frames of different widths.
