The present invention relates to a production line of slats for roller shutters, comprising: a profiling machine; and a foaming machine, integrated in the profiling machine and suitable for dosing a predefined amount of a mixture of polyol and isocyanate in the unit of time inside a hollow, box section profile, partially open while it is being formed by means of an injection nozzle positionable in a predefined dispensing position along said longitudinal direction of advancement. The line comprises an optical acquisition device suitable for capturing images of the jet of the polyol and isocyanate mixture dispensed from said injection nozzle. The line comprises a control system that verifies whether the captured images of the jet are comparable within predefined error margins with said reference image or whether they deviate from it and activates an alarm procedure if a deviation from said reference image is detected.

A slat for roller shutters includes an internally hollow elongated body extending along a longitudinal direction with a first face and opposite second face, designed to turn respectively towards the outside and inside of the compartment closed by the shutter. A cavity along a first longitudinal edge of the body is delimited by a first appendage on the first face, and a second appendage on the second face. A coupling appendage extends from a second longitudinal edge. Two recesses are at ends of the second longitudinal edge. Two notches on the second appendage near the opposite ends extend transverse to the first longitudinal edge, and define, on the second appendage, first and second tabs at opposite ends of the body. Each tab bends against the first appendage to close the coupling cavity at the ends of the body. The first appendage extends continuously from one end of the body.

A vehicle interior assembly includes a tambour door that is moveable along end guides between an open position and a closed position. The tambour door includes a plurality of slats interconnected by a unidirectional cord embedded in a plastic material of each one of the slats. The cord, such as yarn of aramid fibers can be molded-in to each one of the slats to simplified formation of the articulated joints between slats.

A retractable privacy system for roll-up walls and doors is disclosed. In one embodiment, such a retractable privacy system includes one or more drums rotated by one or more motors to draw in or let out one or more flexible sheets from the drum. Multiple motors and drums may work in synchronization to achieve a desired result. In certain embodiments, various inputs are used to automatically open or close roll-up walls and doors. In other embodiments, the retractable privacy system interfaces with a thermostat or security system to achieve a desired result.

A maintenance-free rolling door vacuum slat includes an elongate tubular member forming a cavity with a substantially uniform cross-sectional configuration along its length and forming first and second opposing ends conforming to the cross-sectional configuration. A first cap seals the first end. A second cap seals the second end, a vacuum being formed within the cavity. The first and second caps are joined to the elongate member to form a hermetic seals to render the slat airtight forming a permanent vacuum insulation barrier that requires no maintenance to restore the vacuum within the cavity.

The present invention is related to a roller blind comprising: a length of fabric having a first end connected to a roller tube; a bottom rail have a top piece and a bottom piece releasably secure to one another; a connector for attaching to a second end of the length of fabric; wherein the connector comprises a first retention means adapted to releasably secured to the bottom piece of the bottom rail.

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.
