らる可撓性断熱ホースの改良に関する。[Detailed description of the invention] The present invention consists of a soft synthetic resin band, a band-shaped heat insulating material, and a soft synthetic resin band, which are arranged sequentially from the inside to the outside. This invention relates to an improvement in a flexible heat insulating hose which is formed into a hose-like body consisting of three layers: an inner wall, a heat insulating layer and an outer wall by spirally winding the side edges of the hose with their side edges overlapped and welded together.

ものである。 Conventional flexible insulated hoses, for example,
- As shown in Publication No. 131273, a wide strip and a narrow strip of heat insulating material are used, and the wide strip is bent into a crank shape and its side edges overlap each other. It was constructed so that the heat insulating material was wrapped in the single wide band-shaped body by welding to the wide band.

加工を行ない難いものである。 In a flexible insulated hose configured in this way,
There is an inconvenience in that a special strip supply structure is required to overlap and weld the wide strips while bending them in the middle, and also because the inner and outer walls can only be configured to the same specifications. There was an inconvenience in that the flexible hose could not be utilized more effectively by providing functional differences between the two. In other words, this type of flexible hose is used to flow fluids that require insulation inside the inner wall, or to pass objects that require insulation through it, so it is necessary to maintain the inner peripheral surface of the inner wall in the desired shape. However, increasing the thickness of the outer wall increases the weight of the entire hose and tends to reduce its flexibility, but increasing the thickness of the inner wall increases the hose's original diameter. As a result, the material that has a strong tendency to collapse in the radial direction is further strengthened, and with a small increase in wall thickness, it is possible to improve the shape retention of the inner peripheral surface of the inner wall while avoiding an increase in the weight of the hose. However, it is difficult to perform such processing on the conventional flexible hose.
また、上記従来のものでは、断熱材を備えてい
るとはいえ、内外壁が一連の厚肉の帯状体で構成

伝導が生じ易くなることを避け難いものであつ
た。 In addition, although the above-mentioned conventional type is equipped with a heat insulating material, the inner and outer walls are composed of a series of thick strips, so heat conduction easily occurs through the strips forming the wall. It was hard to avoid what would happen.
そこで本考案では、内外壁を別々の部材から構

熱の伝導を避けられるようにすることに本考案の
目的がある。。 Therefore, in the present invention, the inner and outer walls are constructed from separate members to increase the shape-retaining strength of the inner walls and to avoid heat conduction through the wall constituent materials. If the inner wall is simply made thicker, when the hose is bent, the inner wall will not follow the bending of the outer wall smoothly, and there will be a difference in the degree of bending between the inner and outer walls, causing the insulation to deteriorate. There is a risk that the insulation performance will deteriorate early due to strong compression in some parts, or when performing gentle bending, the inner wall will hardly bend even if the outer wall is bent. Therefore, it is possible to increase the shape-retaining strength of the inner wall without causing such inconvenience, to enable smooth bending of the inner and outer walls, and to reduce the conduction of heat through the wall constituent materials. The purpose of this invention is to avoid this. .

りを良く追随させて、断熱材の局部的な圧縮によ
る劣化を避け易く構成できたものである。 In other words, in order to improve the shape-retaining strength of the inner wall, rather than increasing the thickness of the entire inner wall uniformly, we increased the thickness of parts of the inner wall to ensure sufficient strength against crushing in the radial direction. The hose maintains good flexibility in the bending direction, and by connecting the easily deformable thin part of the inner wall to the outer wall with thin tape, the inner wall can easily follow the bending of the outer wall. Therefore, it is possible to easily avoid deterioration of the heat insulating material due to local compression.
また、内外壁を連結するものは、内外壁構成材
とは別体の薄肉テープであるため、ホース全体の
可撓性を損う虞れは殆んどなく、しかも、薄肉テ
ープとして熱伝導度の低い素材を選択することも
自由にできるものである。 In addition, since the material that connects the inner and outer walls is a thin tape that is separate from the inner and outer wall constituent materials, there is almost no risk of damaging the flexibility of the entire hose. It is also possible to freely select materials with low oxidation.

C is an outer wall formed by winding a soft synthetic resin band 3 in a spiral shape on the outside of the band-shaped heat insulating material 2 forming the heat insulating layer B, and welding the side edge portions together while overlapping each other. A thin tape 4 made of soft synthetic resin is placed between the side end surfaces of the band-shaped heat insulating materials 2, 2 that are adjacent to each other in the axial direction, and both end portions 4a and 4b of the thin tape 4 are placed between the outer circumferential surface of the inner wall A and the inner surface of the outer wall C.
