Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は主として屋内の暖炉から天井を経て屋
外に導く断熱材を介在させた二重壁から成る接続
型煙突に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a connected chimney consisting of a double wall with a heat insulating material interposed therebetween, which leads from an indoor fireplace to the outdoors through the ceiling.

[Conventional technology]

従来、この種の煙突には例えば実開昭55−
141736号公報に掲載されたものがある。 Traditionally, this type of chimney was made using
There is one published in Publication No. 141736.

このものは第５図に示すように筒体ａの上端に
突出環部ｂを形成し、下端に、下位の筒体ａの突
出環部ｂが嵌まる嵌合凹部ｃを設け、突出環部ｂ
と嵌合凹部ｃに互いに係合する係止突起ｄ，ｅを
数箇所突出させ、上下の筒体の突出環部ｂと嵌合
凹部ｃとを嵌合させた後筒体を僅少回わして係止
突起ｄ，ｅを係止させるものである。 As shown in Fig. 5, a protruding ring part b is formed at the upper end of the cylinder a, a fitting recess c is provided at the lower end into which the protruding ring part b of the lower cylinder a is fitted, and the protruding ring part b
The locking protrusions d and e that engage with each other are protruded from the fitting recesses c at several locations, and after the protruding ring portions b of the upper and lower cylinders are fitted into the fitting recesses c, the cylinder is slightly rotated. This is to lock the locking protrusions d and e.

[Problem that the invention attempts to solve]

上記従来の接続型煙突は上下の筒体を嵌合した
後回転させなければならず、従つて真直でない屈
曲した筒体を接続すると所要の向きにすることが
できない場合も生じ接続構造としては好ましくな
い。 In the above-mentioned conventional connected chimney, the upper and lower cylinders must be rotated after they are fitted, and therefore, if the cylinders are not straight and bent, it may not be possible to make them in the desired orientation, so this is not preferable as a connection structure. do not have.

本考案の目的は、前記従来の欠点を除去し、接
続作用が確実で、しかも屈曲筒も所望の向きに接
続できる煙突を提供することにある。 SUMMARY OF THE INVENTION The object of the present invention is to provide a chimney which eliminates the above-mentioned drawbacks of the conventional chimney, has a reliable connecting action, and allows the bent tube to be connected in a desired direction.

[Means for solving problems]

本考案の手段は次の通りである。 The means of the present invention are as follows.

(イ) 筒体１の上端部と下端の周面に密着つば４及
び５を突設し、 (ロ) 上下互いに嵌合した上位筒体１の下端のつば
５と下位筒体１の上端のつば４とを密着させる
く形の締付環６とを備えていること。(a) Close-fitting collars 4 and 5 are protruded from the circumferential surfaces of the upper and lower ends of the cylinder 1; It is provided with a dog-shaped tightening ring 6 that brings the collar 4 into close contact with the collar 4.

[Effect]

下位の筒体１の突出環部２を上位の筒体１の嵌
合段部３に嵌め、締付環６を接合した両密着つば
４，５の外周に位置させて締付けると、締付環６
は断面く形のため互いに密着する。 When the protruding ring part 2 of the lower cylinder body 1 is fitted into the fitting step part 3 of the upper cylinder body 1, and the tightening ring 6 is positioned on the outer periphery of the two joined tight-fitting ribs 4 and 5 and tightened, the tightening ring 6
Because of their rectangular cross-sections, they fit closely together.

〔Example〕

第１図乃至第４図について本考案の具体例を説明
する。 A specific example of the present invention will be explained with reference to FIGS. 1 to 4.

図中符号１は筒体で上端の直径が下端の直径よ

締付環で緊締ねじ７を締付環の切断部に突出した
取付片８，８′にねじ込む。尚図中１′は屈曲筒体
を示す。 In the figure, reference numeral 1 denotes a cylindrical body, which is formed into a conical shape in which the diameter of the upper end is smaller than the diameter of the lower end, and consists of inner and outer double walls 1b and 1c with a heat insulating material 1a interposed therebetween, and a protruding ring part 2 is formed at the upper end. However, a fitting stepped portion 3 into which the protruding ring portion 2 of another cylindrical body 1 is fitted is provided at the lower end. Furthermore, contact flanges 4 and 5 are provided projecting from the top and bottom of the circumferential surface of the cylindrical body 1. 6 is a tightening ring with a rectangular cross section that connects the upper and lower cylindrical bodies 1, 1 as shown in Fig. 3 and fixes both tight fitting collars 4, 5, and a tightening screw 7 is protruded into the cut part of the tightening ring. Screw into the mounting pieces 8, 8'. In the figure, 1' indicates a bent cylinder.

[Effect of idea]

本考案によれば上下の筒体の接続し作用が確実
に行なわれ、特に従来のように筒体を回転させて
係止する構造になつていないため、第４図に示す
ように接続する筒体が屈曲している場合でも所望
の向きに接続し得る効果がある。 According to the present invention, the connection between the upper and lower cylinders is performed reliably, and in particular, since the cylinders do not have a structure in which the cylinders are rotated and locked as in the past, the connecting cylinders can be connected as shown in Fig. 4. Even when the body is bent, the connection can be made in a desired direction.
