A liftable closure element movable between a lowered and a raised configuration, is associated with a portal structure having a compartment for storing the closure element, delimited by a front wall, a space being provided which communicates with the compartment and with the outer environment between the wall and the closure element. An air seal device for the liftable closure includes first and second sealing members adapted to reach a facing position in which they adhere by magnetic attraction to close the transverse space, one connected to the wall for supporting a ferromagnetic plate, the other consisting of a magnetic member fixed to the closure element. The first sealing member includes a base structure which can be fixed to said wall by first and second adjustable fasteners in a position exactly corresponding to the position of the sealing member fixed to the surface of the closure element.

A high speed sliding roll-up door interposed between two rooms at different temperatures has a flexible curtain to close or open a passage of a wall separating these rooms. The roll-up door has two side uprights having guide rails of the side edges of the curtain, and an upper crosspiece near which there is a storage area of the curtain. A device for draining the condensation water present on the curtain includes guide rails having an upper rectilinear portion, close to the shelter area, and a lower rectilinear portion offset with respect to the upper rectilinear portion, between which an inclined portion is interposed which is connected upstream and downstream with the upper and lower rectilinear portion. Below the upper rectilinear portion there is a gutter formation configured to receive the condensation water present on the curtain, when this rises towards the shelter area.

A closing element for roller shutters comprising a central portion designed to be arranged, in use, according to a closing plane of an access opening of a room to at least partly close the access opening, and at least two connecting portions located on opposite edges of the central portion, each of which designed for connection of the closing element with at least one other closing element. Each connecting portion extends about a respective axis and defines a cavity for housing a connecting bar. The connecting portion has an open profile so that the cavity is accessible transversely to the axis.

A device for control by radiofrequency signals (22) of a domestic electrical appliance powered by an electrical power supply network comprising a first electrical conductor (26) and a second electrical conductor (27) for powering the device (22), a coupler (31), a radiofrequency unit (23) comprising an output and/or an input for the radiofrequency signals (28) which is linked electrically to a point of connection (33) of the coupler (31). The coupler (31) is formed by a printed transmission line (32) on a printed circuit board (29), a first end (34) of the line (32) being linked electrically to the first electrical conductor (26) of the device (22), and a second end (35) of the line (32) being linked electrically to a first reference voltage. And the point of connection (33) of the coupler (31) is disposed between the first and second ends (34, 35) of the printed transmission line (32).

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.
