トの外観が悪くなるという欠点があつた。Problems that the invention aims to solve This conventional air conditioning duct has the disadvantage that the sheet-like insulation attached to the duct may peel off over a long period of time. When installing a bent duct in a space, it is difficult and time-consuming to attach sheet-like insulation to the bent duct.
Furthermore, there are disadvantages in that the sheet-like heat insulating material cannot be stuck closely to the three-dimensionally complicatedly curved duct in some places, resulting in dew condensation on the duct during use, and the appearance of the duct becomes poor.

することなどを目的としたものである。 This idea eliminates these drawbacks of conventional air conditioning ducts, and makes it possible to prevent the insulation from peeling off from the duct, to easily attach the insulation to a duct that is three-dimensionally curved, and to make it easier to attach the insulation to the duct. The purpose of this is to make the ducts adhere tightly and provide good insulation, as well as to improve the appearance of the duct.

の被覆場所より移動するのを防止する。Function: The air conditioning duct of this invention is made by covering the outside of the duct with a cylindrical fabric foil that has elasticity and has greater elasticity at both ends than the other parts. The cylindrical cloth foil can be easily attached to a straight duct, and since the cylindrical cloth foil adheres closely to the duct, it provides good insulation and improves the appearance of the duct. Further, since both ends of the cylindrical cloth foil have greater elasticity than the other parts, the cylindrical cloth foil covering the duct is prevented from moving from a predetermined covering area of the duct.
実施例
次にこの考案の空調ダクトを図示した１実施例
について説明する。Embodiment Next, an embodiment illustrating an air conditioning duct of this invention will be described.
ダクト１は三次元的に複雑に屈曲した中空体で
ある。このダクト１の外側を後記の円筒状の編物
２で被覆した空調ダクト３である。円筒状の編物
２は全体が伸縮性を有するとともに両端部２′が
他の部２″より伸縮性を大きく、かつ円筒状の編
物２の他の部２″の径はダクト１の外径より小さ
くしたものである。 The duct 1 is a hollow body that is three-dimensionally curved in a complicated manner. This is an air conditioning duct 3 in which the outside of the duct 1 is covered with a cylindrical knitted fabric 2 to be described later. The entire cylindrical knitted fabric 2 has elasticity, and both ends 2' have greater elasticity than the other parts 2'', and the diameter of the other part 2'' of the cylindrical knitted fabric 2 is larger than the outer diameter of the duct 1. It is a smaller version.
この実施例において、屈曲したパイプのダクト
１に伸縮性を有する円筒状の編物２を拡げるよう

２′が着用時の靴下の上端部と同様に止めバンド
の役目を果して円筒状の編物２が所定のダクト１
の被覆場所より移動しにくくなる。 In this embodiment, when a cylindrical knitted fabric 2 having elasticity is spread out to cover a bent pipe duct 1, the cylindrical knitted fabric 2 contracts due to its own contraction force, and the bent pipe duct 1 is covered with a stretchable cylindrical knitted fabric 2. A cylindrical knitted fabric 2 that adheres well along the
Since the contraction force at both ends 2' is larger than that at other parts 2'', the contraction is large, so both ends 2' of the cylindrical knitted fabric 2 act as a fastening band in the same way as the upper end of a sock when worn, and the cylindrical knitted fabric 2 The shaped knitted fabric 2 is a predetermined duct 1.
It will be more difficult to move than the covered area.

It may also be made of a bias-woven stretchable woven fabric or a stretchable nonwoven fabric sewn into a cylindrical shape. Further, the ends of the cylindrical cloth foil and the other portions thereof do not necessarily have to be made of the same cloth, but may be made by sewing different cloth foils together.

In the one shown in FIG. 3, a protrusion 4' is provided at the end of the duct 4, and the protrusion 4' This is an air-conditioning duct in which the duct 4 near the end is covered with the highly elastic end 5' of the cylindrical cloth foil 5 to prevent the cylindrical cloth foil 5 from moving, as shown in Figure 4. Then, a recess 6' is provided at the end of the duct 6, and the highly elastic end 7' of the cylindrical cloth foil 7 is covered with the recess 6' of the duct 6, so that the cylindrical cloth foil 7 moves. This is an air conditioning duct that prevents

The cylindrical fabric foil can be easily attached to ducts that are three-dimensionally curved in a complicated manner, and the cylindrical fabric foil always adheres well to the duct without peeling off, providing good insulation. At the same time, the appearance of the duct can be improved. Furthermore, since both ends of the cylindrical cloth foil have great elasticity, it is possible to prevent the cylindrical cloth covering the duct from moving from a predetermined covering area of the duct.
