Abstract: A screen retraction mechanism for a retractable screen assembly, the screen retraction mechanism comprising: a roller housing; a roller spinably mounted within the roller housing and for rolling a screen material sheet thereon; a torsion spring coupled to the roller for rotationally biasing the roller; and a tension adjuster coupled to an end of the torsion spring and configured to move in and out of engagement with the roller housing, wherein the tension adjuster is spinnable to selectably tension the torsion spring when out of engagement with the roller housing.

Abstract: A brake arrangement, for a retractable screen arrangement in which the a screen roller applies a retraction force to the screen and brake arrangement, includes a brake arrangement, for providing a braking force between the brake arrangement and a track which guides the brake arrangement, to resist retraction. The brake arrangement provides a brake member with a friction surface for contacting the bearing surface; a brake member support for supporting the brake member; and a forcing arrangement for forcing the friction surface against the bearing surface. The forcing arrangement includes a biasing arrangement for biasing the friction surface onto the bearing surface, and a force-increasing arrangement for increasing the force with which the friction surface engages the bearing surface. The force increasing arrangement converts a frictional force between the friction surface and the track into additional contact pressure force of the friction surface onto the guide track.

Abstract: A retractable screen that is integrated within a wall cavity and fixed to an internal door frame. The screen has a base frame mounted to the support. The base frame comprises a lower elongate member a U shaped upper elongate member and two U shaped side elongate members each having an upper part and a lower part respectively fixed to the upper and lower elongate members. A lower guide track is mounted to the lower elongate member. An upper guide track assembly is mounted within the upper elongate member. The upper guide track assembly includes an elongate insert member with an upper guide track mounted therein and the elongate insert member is configured for insert installation into the upper elongate member. The side elongate members house a roller assembly for a screen.

Abstract: 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.

Abstract: A mounting arrangement comprised of a first component for attachment to a support, and a second component supportable by the first component. The first component has a first side which is in use distal from the second component and provides a supporting portion spaced from the first side. The second component provides an engagement portion for engagement with the supporting portion. The mounting arrangement provides a restraining part moveable between a restraining configuration for restraining disengagement of the engagement portion from the supporting portion, and a release configuration for allowing disengagement of the engagement portion from the supporting portion. The mounting arrangement further provides a securing component which is insertable between the second component and the first side of the first component to restrict disengagement of the engagement portion from the supporting portion.

Abstract: 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.

Abstract: An apparatus for retaining a blind comprises: a first elongate element for attachment to a supporting structure; a second elongate element attachable to the first elongate element, in order to at least partially form a guide track providing a guide channel in which a part to be guided may be constrained, the first and second elements together at least partially defining the external surfaces of the guide track. The second elongate element is attachable to the first elongate element by displacement of the second element relative to the first element. The direction of displacement may be a direction substantially transverse to the direction of elongation of the first element.

Abstract: A retractable screen for extending across an architectural opening is disclosed. The retractable screen includes a fixed side having a fixed screen post; a displaceable handle post having an upper region and a lower region, the displaceable handle post is displaceable away from the fixed side towards a closed position, and is displaceable towards the fixed side back into an open position; at least one of an upper guide track and a lower guide track which is operatively engaged with the upper or lower region of the handle post and guides movement of the handle post between the open and closed positions.

Abstract: The present invention relates generally to barriers for architectural openings, in particular to a screen apparatus and method for screening off an architectural opening. The screen apparatus includes an elongated overhead frame member, a transverse fixed side frame member, a displaceable side frame member, and an elongated articulated bottom frame member. A screen member extends between the frame members, the screen member being interchangeable between a collapsed condition when the screen is open and an extended condition when the screen is closed by movement of the displaceable side frame member.
