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 fabric fire rated door is described. The door utilizes a fire resistant fabric curtain with an end lock attachment. A tubular steel shaft is driven by an internal tube motor. The shaft is supported to minimize deflection. Single door shafts can also be joined together with a coupler shaft to create infinitely wide doors. The coupler shaft is spring loaded to act as a take up reel for a coupling curtain which will overlap each adjacent single door shaft. All curtains are attached to the same bottom bar. A hood covers the shaft, curtain, and the supports that run across the width of the door. The curtain travels over these horizontal supports as it drops down through the hood opening. The horizontal supports keep the curtain in position for proper seal during a fire/smoke event.

A tubular electromechanical actuator includes an assembly, a casing and a closure element for closing off the casing. The assembly includes an electronic control unit, an electric motor, a reduction gear and an output shaft. The casing is hollow and configured to house the assembly. The casing includes a first end and a second end. The output shaft protrudes from the casing at the first end of the casing, in an assembled configuration of the actuator. The closure element protrudes from the casing at the second end of the casing, in the assembled configuration of the actuator. The actuator also includes an interface element. The interface element is arranged between the closure element and the electronic control unit. In addition, the interface element includes a housing containing an element for preventing play between the closure element and the interface element along the axial direction of the actuator.

An optoelectronic component includes a carrier, and a light source arranged on a surface of the carrier, said light source including at least one luminous surface formed by at least one light-emitting diode, wherein a transparent converter-free spacer is arranged on the luminous surface such that a distance is formed between the luminous surface and a spacer surface of the spacer facing away from the luminous surface, and wherein the light source is potted by a potting compound such that the spacer surface is formed extending flush with a potting compound surface facing away from the surface of the carrier and a surface formed by a spacer surface and the potting compound surface is plane.

A roll-up wall system including a frame having a longitudinal axis, a first roller disposed in the frame, a second roller disposed in the frame, and a tube disposed in the frame. A screen may be connected to the tube. The screen may be supported by the first roller and the second roller. Further, the screen may be movable between a first configuration and a second configuration. In the first configuration, the screen is rolled around the tube which is spaced a first distance from the first roller. In the second configuration, the screen forms a barrier adjacent the frame, and the tube is spaced a second distance from the first roller. The second distance may be less than the first distance. Also, the roll-up wall system may be an acoustic barrier which achieves a Sound Transmission Class rating ranging from approximately 31 STC to approximately 53 STC.
