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 shutter includes a window frame, a plurality of blade structures, an intake driving unit and an airflow guiding unit. The window frame has an upper frame portion, a lower frame portion and two side frame portions. The blade structures are disposed on the window frame, and each has a through hole and a plurality of outlets. The intake driving unit is disposed in the upper frame portion. The airflow guiding unit is disposed in at least one of the two side frame portions. Each of the through holes of the blade structures communicates with the inside of at least one of the two side frame portions.

The present invention is a gear driven louver shutter system, wherein each louver of the shutter system is attached to the end of a pinion at both its ends. The base of each pinion is engaged with two gear strips disposed within a frame member. The arrangement is provided such that when one louver is adjusted, all the louvers in the shutter system will move accordingly. The gear strip and pinion system eliminates the need for a tilt bar. In a preferred embodiment, louvers of the system engage with pin connectors or clips to attach to the pinions. The pin connectors or clips allow for the louvers to attach to the pinons without requiring a tool. In an embodiment, the louvers will have a S-shape profile, to allow for light to be completely blocked when the shutter system is closed.

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).

A barrier includes a post, a support beam coupled to the post, and multiple slats coupled to the support beam. The multiple slats are also coupled to a flexible elongate member. The flexible elongate member is also coupled to a driving mechanism. As the driving mechanism moves the flexible elongate member, the flexible elongate member causes the multiple slats to rotate between a closed position and various open positions.
