A stacking panel covering for an architectural opening includes a headrail and a plurality of suspended from the headrail. The panels form an overlapped stack at one end of the headrail when the stacking panel covering is opened, and cover the architectural opening when the stacking panel covering is closed. The panels are piggybacked on those adjacent thereto, so that they stack, one behind the next, when the stacking panel covering is opened, and so that each pulls the next adjacent thereto as the stacking panel covering is being closed. The panels themselves may be planar, or convexly curved in a horizontal direction and substantially straight in a vertical direction.

A foldable structure for a sunshade, a shutter or a fence, comprising at least one guiding member (10); a plurality of displaceable elements (20) slidably connected to said guiding member (10) forming a row (2), a stroke end (54), a first actuator (31) connected to first displaceable element (20) of the row (2), foldable spacers (40) connecting each pair of successive displaceable elements (20), and a spacer guide (50) including successive first portion (51), second portion (52), third portion (53), wherein the second portion (52) urge the foldable spacers (40) from a first folding position to a second folding position; and wherein a second actuator (32) produces a relative movement between the second portion (52) of the spacer guide (50) and the stroke end (54) to adjust the longitude of the third portion (53), said second actuator (32) being in coordination with the first actuator (31).

A collapsible wall for covering an opening in a structure when the collapsible wall is in an extended position. The collapsible wall including a plurality of frame sections engaged with each other to form a telescoping frame movable between the extended position and a retracted position, the frame sections forming at least a portion of a face of the collapsible wall and defining an aperture through the face. A panel is removably engaged to the frame sections, the panel covering the aperture when the panel is disposed in a closed position.

A slat device (1) comprising a plurality of slats (2) arranged parallel to one another, displacement means (9, 10) for displacing the slats (2) between and in a stacking zone and a sliding, and a guide profile (3), which is arranged on a lateral side of the slats (2), wherein a slat (2), on the said lateral side, is provided with a guide element (5), corresponding with the guide profile (3), for guiding the respective slat (2) relative to the corresponding guide profile (3, 6) during its displacement motion between and in the stacking zone and the sliding zone, such that the guide element (5) is rotatable over a certain angle relative to the guide profile (3) about an axis according to the longitudinal direction of the guide profile (3).

To keep the same size motor when panel numbers are varied, the invention includes a torsion spring counter balancing mechanism for a stacking panel shutter door, wherein one end of the or each torsion spring is fixable to a drive transmission shaft of the stacking panel shutter door, the drive transmission shaft being adapted to raise and lower the or each shutter of the stacking panel shutter door; and the other end of the or each torsion spring is fixable to a separate rotatable member of the stacking panel shutter door; and whereby the mechanism is provided with means adapted to enable both the drive transmission shaft and the rotatable member to rotate, during opening and closing of the stacking panel shutter door, in such a manner as to cause respective ends of the or each torsion spring to travel at different speeds during the opening and closing sequence.

A combination awning and shutter (1) having at least two panels (4, 5, 15, 16, 17) of substantially rectangular configuration foldably attached along contiguous sides so that when folded together and supported by support rods (8) or scissor hinges (18) and brackets (19) can be maintained in an angular awning position and when unfolded act as a storm or security shutter over a window or door opening and further securable by the support rods secured in eye bolts (11) on each side of an opening.

In example implementations, a track of a vertically stacking door is provided. The track includes a vertical track, a track coupling coupled to the vertical track, a first curved track portion coupled to the track coupling, a second curved track portion coupled to the track coupling, and a ramp coupled to the vertical track before the track coupling.

An openable sunscreen device with adjustable slats (3) moved by at least one distance adjustment member (21) between opened (O) and closed (C) conditions. Each slat (3) has an axle (9) whose ends (11) slide along a first site for sliding (15) of a side guide (17). Each slat (3) has an inclined arm (23) provided with a slider (25). A rotation member (27) provides for rotation of the slat (3) around its axle (9) and includes a longitudinal track element (31) parallel to the site for sliding (15) and a corresponding transversal track element (33). Each transversal track element (33) intersects the longitudinal track element (31) at a respective switch element (35) rotatable between a rotating condition in which it (37) is aligned with the respective transversal track element (33) and a sliding condition in which it (37) is aligned with the longitudinal track element (31).

Foldable wall systems that greatly reduce traditional wall building processes are contemplated. Suitable foldable wall systems comprise a plurality of panels that form a wall. The panels can be stored or deployed from a housing that is mounted on one or more vertical columns. It is contemplated that the panels comprise one or more track elements that travel within one or more tracks to guide the panels between the stored and deployed configurations.
