摘要:
Flexible ventilation ducts require an alternative means of connection to traditional rigid ducts. A ventilation ducting connector (6) is therefore provided for connecting ventilation ducting sections (2,4) formed from a compressible material. The connector (6) is arranged to receive the free ends of two contiguous ducting sections (2,4) such that the ducting sections define a continuous air conduit. The collar (6) is reconfigurable between an open configuration in which the ducting sections (2,4) may be freely inserted into the collar (6), and a clamped configuration in which it surrounds part of each ducting section (2,4) and provides a compressive force to hold the ducting sections in a relative position. The collar comprises at least one inwardly extending projection (24,28) arranged on its inner surface to penetrate the outer surface of at least one of the ducting sections (2,4) when the collar (6) is in the clamped configuration.

The invention provides an air duct assembly comprising: an air duct (16) elongate in a longitudinal direction (24), the air duct (16) comprising a sidewall (18) that is pliable, the sidewall (18) being tubular and defining an interior (26) of the air duct (16) and an external area (28) outside the air duct (16); an overhead support member (36, 36a, 36b, 36c) in the external area (28) outside the air duct (16); a hoop (34) disposed within the interior (26) of the air duct (16), the hoop (34) providing the sidewall (18) with support in a radial direction (64) that is substantially perpendicular to the longitudinal direction (24); and a bracket (78) passing through an opening (80) in the sidewall (18) and extending from the hoop (34) to the overhead support member (36), the bracket (78) being more rigid than the sidewall (18), and the bracket (78) cooperating with the hoop (34) to subject the air duct (16) to tension in the longitudinal direction (24), the bracket (78) and the hoop (34) being non-adjustably coupled.
摘要:
A flexible ventilation duct production method, wherein an inner layer using at least one or more of aluminium PET, polyester, metalised OPP, metalised polyester and/or PVC; an insulation layer comprised of rubber, polyethylene liners, polyester fibres or similar insulation materials; a flexibility providing steel wire taking its shape from being spirally wound around a cylinder; and an outer layer using at least one or more of aluminium PET, polyester, metalised OPP, metalised polyester and/or PVC are laminated by being wound to a constantly rotating cylindrical shaft by means of being given in a certain order to form an integrated, holistic structure between all the factors, which is constantly rotated around its own axis in strip plates and is constantly fed to the mentioned cylindrical shaft, by meanwhile providing complete lamination with the applied chemicals.

摘要:
An air duct for transport or distribution or suction of air, the duct having walls (2) made of a woven or non woven fabric or foil, wherein the duct comprises - wall (2) of the duct, which has a cross section of a triangular or rectangular shape, - at least one upper longitudinal bearing profile (1), in which an upper corner (4) of the duct is embedded, and - at least one lower longitudinal delimiting profile (3) for setting a position of a lower corner (5) of the duct, and
at least one further profile (1, 3), in which a further corner (4, 5) of the duct is embedded, and which is adjustable in a fixed position in respect of the upper bearing profile (1) and / or the lower delimiting profile (3).
摘要:
A duct member (1,10) for air transportation and distribution, which comprises a wall (2,22) made of woven or nonwoven fabric or foil, wherein the wall is provided with a system of through holes (5,25) for air passage, the duct member (1, 10) further comprising at least one guiding element (6) for guiding a regulating strip (3) along at least some of the systems of holes (5, 25) for regulating the amount of the air distributed through the through holes (5, 25).
