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.

A door, in particular a high-speed industrial door, with an intelligent door leaf is disclosed. The door has a door leaf which is guided by lateral guides and covers a door opening, and which has a first and a second side, a driving means for moving the door leaf between an open and a closed position, a door control means for controlling the driving means, as well as an electrically self-sufficient door leaf means arranged in the door leaf. The door control means also has a first communication unit. In addition, the door leaf device comprises at least one sensor unit for detecting at least a physical quantity, an energy converter which converts non-electrical energy into electrical energy, a second communication unit and at least one actuator unit. The first and second communication units communicate wirelessly with each other.

An kinetic object protection system for protecting a space in a building or vehicle comprising a protective barrier including one or more sheets of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets, nets, or mesh which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the barrier from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the barrier to transition from the retracted state to the deployed protective state such that in the protective state, the barriers are adapted to be resistant to penetration by the kinetic objects such as vehicles.

An insertable roll-up door for a vehicle is formed from a header, left and right guide members and, optionally, a bottom sill. These components are assembled at a first geographic location to form a dimensionally stable subassembly. A flexible door panel is connected with a roller and installed in the subassembly where ends of the roller are received at top portions of the guide members and supported to rotate about a roller axis to wind the door panel onto and off from the roller. Edges of the door panel are guided by the guide members to move vertically to open and close the door. The assembled door is shipped to a second location to be installed on a vehicle. At the second location, an opening is created in the vehicle sized to receive the door. The door is inserted in the opening and fixed to the vehicle with fasteners.

A multi-curtain assembly has curtain segments of a retractable curtain, the curtain segments having leading edges affixed to a bottom bar and extending between opened and closed positions by winding on and unwinding from a barrel assembly, each curtain segment being optionally connectable to the other curtain segment adjacent thereto by a fastener at respective adjacent edges of each curtain segment during unwinding. The multi-curtain assembly includes: a motor driving the barrel assembly of a first curtain segment, adjacent and further curtain segments meeting one another at an interface angle; and at least one curtain driving interface that passes along a rotational barrel driving force from the barrel assembly of the first one of the plurality of curtain segments. The driving interface being an interface for angle of 90 degrees, of less than 90 degrees, or greater than 90 degrees, or an interface for barrel assemblies at different heights.
