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.

An upper guide track assembly for a retractable screen is described. The assembly comprises a U shaped guide channel, a track attachment member for attaching the assembly to a support, a track outer member connectable to the attachment member and a screen retaining member within the guide channel. The retaining member receives and retains an upper edge of a screen. The retaining member has two resilient wings extending from either side of the body. Each wing is biased towards a position in which the distal end of each wing is away from the body. The wings are moveable against the bias to a retracted position. When the retaining member is retained in the guide channel, each wing is held in the retracted position against the bias. This allows an upper edge of a screen retained by the screen retaining member to be biased in the vertical direction.

The disclosure relates to the field of providing a flexible screen which is extensible and retractable across an opening. It is desirable to provide a bottom guide track which is convenient to fit and with a low profile. The disclosed guide track arrangement provides an elongate mounting member for securing to a support that forms part of the opening, and which provides at least one elongate connection recess; and an elongate track member, formed separately from and attachable to the mounting member, and having a track region with an elongate guide recess for slidingly retaining an edge of a flexible screen. The track member has at least one engagement part engageable into the complementary connection recess by lateral movement of the track member to connect the track member to the mounting member.

A chain structure for a screen device comprises a plurality of chaining unit members (10). Each chaining unit member comprises a bridging portion (11), and comprises a first pivotal connection portion (12) and a second pivotal connection portion (13) that are disposed on two opposite sides of the bridging portion. The chaining unit members are connected by means of the first pivotal connection portions and the second pivotal connection portions, so as to form a chain structure (1). By means of the structure arrangement, the plurality of chaining unit members is serially connected; in this way, when the chain structure slides in the screen device, by means of the swing and pivotal movement of the bridging portions, the problems in the prior art that a member is likely to deform, the slide is not smooth and there is noise can be avoided.

An assembly for closing an opening comprising a door panel adapted for sliding movement between an open position and a closed position, a first extendable member located at a first edge of the opening and extendable towards an opposed second edge of the opening, and a second extendable member located at the second edge of the opening and extendable towards the first edge of the opening, and wherein the door panel includes a stop member attached thereto and movable therewith, the location of the stop member defining the limit of movement of the first extendable member towards the second edge of the opening, and the limit of movement of the second extendable member towards the first edge of the opening.

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.

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. While 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.

A device (1) is described for stopping, releasing and restoring the position of roller-type window nets (3, 48), comprising: a fixing shaft (13) having a coupling groove (15) formed in a front external circumferential surface thereof and an insertion groove (16) formed in a rear surface thereof; a ball rotor (18) inserted into the fixing shaft (13) and coupled to the external circumferential surface of the fixing shaft (13), including a front portion coupled by means of a spring (30) and having a conveying groove (20) formed in a surface thereof for conveying a ball (40) and a guide jaw (38) formed in a central part thereof, wherein the ball (40) is inserted into the conveying groove (20); and an outer rotor (42) coupled to the conveying groove (20) via the ball (40) and having a rotation groove (44) formed in an internal circumferential surface thereof, wherein the ball (40) is coupled to the rotation groove (44) to rotate.

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. Whilst 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.

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, a bottom rail mountable to and between the first and second side rails, a handle coupled to and between the top and bottom rails, a flexible panel extending between the handle and one of the first and second side rails, and at least one biasing member carried by at least one of the first side rail, the second side rail, the top rail and the bottom rail to apply a force to draw the handle toward the one of the first and second side rails, wherein the top and bottom rails are each expandable in length to accommodate mounting of the retractable, flexible panel door to door frames of different widths.
