Description of the Related Art A flexible duct of this type is generally formed by inserting glass wool between a porous inner sheet and a synthetic resin outer sheet, and winding the glass wool around a coiled metal wire to form a tubular shape. , It can be bent with a certain degree of freedom.

している。By the way, as shown in FIG. 3, such a flexible duct is bent to form a pipe, or when the length of the pipe is long, the central portion does not hang down. A flexible duct is hung by winding a wire around the flexible duct and hooking the wire on a ceiling or the like. In FIG. 3, reference numeral 10
Is a flexible duct, and A is a wire for suspension.

レキシブルダクト１０が変形する。However, as described above, the flexible duct 10 is formed by inserting glass wool between the porous inner sheet and the synthetic resin outer sheet and winding the glass wool around a coiled metal wire to form a tubular shape. Therefore, the shape retention is poor, and when the wire A is hung around and hung down, the wire A is fitted between the coiled metal wire rods,
The wire A bites into the flexible duct 10 and the flexible duct 10 is deformed.
【０００５】このように、フレキシブルダクト１０が変

障が生じるという問題がある。As described above, when the flexible duct 10 is deformed, there is a problem that the air flow in the flexible duct 10 is hindered.
【０００６】そこで、この発明は、フレキシブルダクト
の吊り下げによる変形を防止しようとするものである。Therefore, the present invention is intended to prevent deformation due to suspension of the flexible duct.

吊り下げ孔を形成したのである。In order to solve the above-mentioned problems, the present invention has a glass wool layer sandwiched between an inner sheet and a synthetic resin outer sheet, which is formed into a tubular shape with a coiled metal wire. In the shape-maintaining flexible duct, the synthetic resin outer surface sheet is integrally formed with strip-shaped portions projecting to the outer side along the length direction, and the suspension holes are formed at predetermined intervals in the strip-shaped portions.

り、ぶら下げ部分に変形が生じない。As described above, since the synthetic resin outer sheet is formed integrally with the strip portion and the suspending hole is formed in this strip portion, when a wire is hung through the suspending hole to hang it, the load of the flexible duct will be increased. It is added to the entire surface and the hanging part does not deform.

２、グラスウール層３、塩化ビニル等の合成樹脂外面シ
ート４を順次巻き付けて円筒状に形成したものである。The flexible duct 1 comprises a core material formed by winding a metal wire in a coil shape, a porous sheet made of glass cloth, a non-woven fabric or the like, an inner surface sheet 2 such as a synthetic resin sheet, a glass wool layer 3 and a synthetic material such as vinyl chloride. The resin outer surface sheet 4 is sequentially wound to form a cylindrical shape.

せ部分をさらに折り返すことによって形成されている。On the outer surface of the synthetic resin outer sheet 4, a band-like portion 5 is integrally formed along the length direction so as to project to the outer surface side. When the synthetic resin outer surface sheet 4 is wound around the glass wool layer 3 and formed into a cylindrical shape, the strip-shaped portion 5 is formed by overlapping both side edge portions and further folding back the overlapped portion.
