    摘要： A fire or smoke barrier (1) having a head box (2) for housing a curtain (4) which is open at its underside to allow the curtain to be deployed and withdrawn. The head box (2) houses a roller (3) for the curtain (4) to be rolled from for deployment and rolled back onto for withdrawal and attached at the bottom of the curtain (4) is a bottom bar (7) for weighing down the curtain (4) when deployed. The head box (2) has one or more apertures (14, 15) for cleaning air circulation and being provided at the, or each, aperture (14,15) with a spring (22) loaded trap (16,17) normally held open by a fusible link (31), the link fusing (31) in event of fire.

    摘要： A fire curtain assembly is presented that is collapsible for easy transport and quickly and easily assembled for use. This system includes a panel having a plurality of support members positioned in approximate parallel spaced alignment to one another across the panel. The support members have a center section and opposing end sections that selectively connect to the center section thereby forming rigid supports across the panel. End sections have a handle member that connects to a pushrod having a locking pin connected to its end. The locking pin selectively engages and disengages the center section. The handle members have detents that fit within detent sockets thereby holding the handle members in a withdrawn position or an inserted position.

    摘要： A non-directional smoke control damper includes a central blade (11), a plurality of outer blades (12) and a blade advancing/retreating device; an outer edge of the central blade (11) overlaps with an opening edge of the plurality of outer blades (12); a support shaft (110) is disposed to pass through the overlapping portion of the edges; a rear end of the support shaft (110) is coupled through a shaft coupling plate (230); and if the central blade (11) advances forwards, the plurality of outer blades (12) advance forwards in order so that a gap is formed at each edge between the central blade (11) and an adjacent outer blade and between a prior-order outer blade and a posterior outer blade to form a blowing passage, thereby allowing an air current to flow into the vestibule through the blowing passage.

    摘要： An air flap device (10) for a cooling or/and freezing appliance of kitchen equipment comprises an air flap (18) which is mounted so that it can pivot about a first axis of rotation (20) between an open position and a closed position, uncovers an air passage opening for the passage of air in the open position and at least substantially blocks the air passage opening against the passage of air in the closed position, and a motor-driven flap operating mechanism for pivoting the air flap. According to the invention, the flap operating mechanism comprises a rotary member (26) which is disposed so as to be driven about a second axis of rotation (28) as well as a separate force transmission member (32) which serves to transmit force between the rotary member and the air flap, is coupled to the rotary member at a point lying eccentrically to the second axis of rotation and is coupled to the air flap (18) at a point lying at a distance from the first axis of rotation.

    摘要： The invention relates to a protection device for ventilation ducts where at least one duct opening for the supply and/or evacuation of air is provided, in particular for fire protection of air conditioned rooms for information technology installations. To separate the protection zones in the event of an emergency according to high safety standards, it is suggested that said protection device comprises at least one protection slide that is supported in a vertically displaceable manner and furthermore includes a sliding mechanism by means of which said protection slide is movable from an open position to a closed position of said duct opening, said duct opening being completely covered by said protection slide in said closed position.
