A building structure 1a, 1b, and 1c incorporates an outer wall 6 provided on a lower side of a sloped ceiling 2 in a slope direction, an opening part 5 formed in the outer wall 6, a box-shaped groove part 15 formed at a lower end of the sloped ceiling 2 along the outer wall 6 and having a lower opening 14 opened downward, and an attachment part 17 provided inside the groove part 15 and to which an upper end part of a light shielding material 16 that shields light incident on the opening part 5 is attached, wherein the groove part 15 is a ceiling-embedded type embedded in the sloped ceiling 2, and a lower end of a side plate of the groove part 15 on a side opposite to the opening part 5 is lower than a height of a lower surface of a frame 23 on an upper side of the opening part 5.

Disclosed is a roller-shutter-type guardrail, which includes: a shutter fixing seat provided with an insertion hole; and a shutter assembly, the roller shutter assembly including a shutter mounting seat, a rotating shaft being rotatably mounted on the roller shutter mounting seat, the rotating shaft being provided with a shutter cloth, a connecting member being arranged on a free end of the shutter cloth, and the shutter mounting seat being provided with a locking mechanism for limiting or releasing rotation of the rotating shaft.

A lining is provided that covers doors or windows to provide protection against all inclement weather conditions. The lining prevents sunlight or any other type light from entering inside a room. The lining that includes horizontal slotted blinds that are operated manually using a flat cord. The horizontal slotted blinds work using tongue and groove concept.

The enclosure comprises: a partition (1) of panels (2) provided with longitudinal grooves (3) and a space for mounting a door (6); and a door (6) comprising: an upper box (7); and two vertical posts (9) with vertical guides (30) for moving a closing element (10), in addition to longitudinal channels (15) defining passages, with the longitudinal grooves (3), for housing fastening elements (16, 17) that can be vertically moved between a position wherein the door (6) is held and a position wherein the door (6) is released. The door comprises means for ensuring peripheral tightness in the closed position.

A roller blinds structure, having a casing provided with side walls that define an inner chamber intended to house drive means linked to a blind or similar, and guide profiles able to be located at opposite ends of the casing, which are configured to guide the blind or similar, the guide profiles being intended to extend in a downward direction with respect to the positioning of the casing, including an attachment system to attach each one of the guide profiles and the casing. The attachment system includes a first interconnection member able to be coupled to one end of the casing by means of fixing means and a connector member able to be coupled to the first interconnection member by means of first releasable quick-fit means and able to be coupled to a respective guide profile by means of second releasable quick-fit means.

A screen assembly for a window includes a pair of parallel and spaced apart side rails locatable against respective sides of a window opening, and a head assembly including a roller upon which is wound a screen. The head assembly extends between the side rails and is adapted to be mounted on upper ends of the side rails to be supported thereon against and/or adjacent to an upper side of the window opening. Each side rail is linearly extendable whereby the upper and lower ends of the side rails frictionally engage upper and lower faces of a window opening to secure the side rails, and the head assembly mounted thereon, in place within the window opening.

Illustrative configurations of greenhouse shading systems are disclosed. One illustrative system includes a plurality of main trusses supporting a translucent material defining an interior space, a plurality of gantries; and a plurality of shades attached to the gantries and the main trusses. The main trusses, gantries, and shades cooperate to move the shades between a closed position and an open position thereby regulating the amount of light the entering interior space of the greenhouse.

A high-speed roll-up door for separating two rooms at different temperatures includes a flexible curtain to close or open a passage of a room separation wall, which passage is delimited, by a portal structure which includes a pair of hollow rails for guiding the curtain. The lateral edges of the curtain have projections for engaging cavities formed between the successive teeth of gear wheels for controlling the movement of the curtain. In the open condition of the door the curtain is received in an upper shelter area axially delimited by two guide panels having specular guide paths. Each guide panel comprises has a seat of a respective gear wheel arranged away from the wall to which the portal structure is associated with, and under the guide panels is prepared a tray for collecting the condensation water present on the curtain, to allow the curtain to be collected entirely above the tray.

This disclosure presents a safe high speed roll-up door with spiral brackets. To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.
