That is, each bolt 4 is connected to the seat plate 8 through a universal joint formed by slidingly fitting the two bolts, and each blind hole 9 is recessed in the side surface of the seat plate 8, and from the recessed part 9a. The above bolt with ball joint can be rolled sideways.

A bolt insertion notch 6 corresponding to the above is provided, and the bolt 4 with the ball joint can be inserted into the notch 6 and raised onto the flange. In addition, an eye nut 5 equipped with a ring 5a is prepared, and the eye nut 5 can be fixed to the upper surface of the collar by screwing the bolt 4 raised up onto the flange, and a tool is inserted into the ring 5a of the eye nut 5. The lid 3 is inserted between the nut 5 and the ring-shaped seat 8 by turning the nut 5.
Tighten the flange 3a to seal it tightly. Similarly, the eye nut 5 is loosened and the ball joint bolt 4 is rolled in the radial direction to allow the lid 3 to be opened.

短管に閉合された蓋上へ直立させ、これに六角ナ
ツトを螺合して蓋の締付け、密閉を図る構成を採
つていた。 Conventionally, when attaching a cleaning port to a bent pipe, a short pipe with a flange is set upright from the periphery of the window, a lid with a window stopper is closed to the flange of the short pipe, and a bolt is attached to the underside of the flange. The bolt is rotatably attached to the protruding bearing plate using a pin shaft, and the bolt is made to stand upright on the lid that is closed to the short pipe using the pin shaft as a fulcrum, and a hexagonal nut is screwed onto this to secure the lid. It was designed to be tightened and sealed.
上記より理解されるように掃除口用に鍔付の短
管を使用するため、ベンド管の外曲部、即ち曲げ
配管部から該掃除口部が大きく飛び出る構造とな
るばかりか、短管の開口部がベンド管の窓より非
常に高い位置となるため、ベンド管内を臨める視
野が非常に狭いものとなつて汚損状態の確認、掃
除に極めて不便となるばかりか、掃除具、腕等の
出し入れ角度も制約を受け、掃除範囲も限られた
ものとなる。 As can be understood from the above, since a short pipe with a flange is used for the cleaning port, not only does the cleaning port protrude greatly from the outside curved part of the bent pipe, that is, the bent piping part, but also the opening of the short pipe Since the part is located very high above the window of the bend pipe, the field of view looking into the inside of the bend pipe is very narrow, which not only makes it extremely inconvenient to check for dirt and clean it, but also makes it difficult to put in and take out cleaning tools, arms, etc. The scope of cleaning is also limited.
加えて、蓋の栓は短管へ深く嵌入しつつベンド
管壁(窓壁)へ嵌合する非常に長い嵌合しろが必
要となつて、蓋が徒らに重く扱い憎いものとな
る。 In addition, the lid plug needs to have a very long fitting margin that fits deeply into the short pipe and into the bend pipe wall (window wall), making the lid unnecessarily heavy and difficult to handle.
更に六角ナツトでは締付が不安定で締付け作業
に大きな労力を要し、これを軽減するためアイナ
ツト等を用いると更に突出高さが高くなるのでこ
れを使用することもできず、ボルト支点がピン軸
構造では強力な締付けに対し強度に欠け、錆、薬
品劣化等で折損する恐れがある等の数々の短所を
有する。それにも拘らず今日まで殆んど改善を見
ることなく使用されてきたのが実情である。 Furthermore, with hexagonal nuts, tightening is unstable and requires a lot of effort, and if you use an eye nut to reduce this, the protrusion height will be even higher, so it is impossible to use this, and the bolt fulcrum is pinned. The shaft structure has a number of disadvantages, including a lack of strength against strong tightening and a risk of breakage due to rust, chemical deterioration, etc. Despite this, the reality is that it has been used until today with almost no improvement.
本考案は掃除口付ベンド管の上記欠点を一掃
し、上記の如き実情を抜本的に打開する。 The present invention eliminates the above-mentioned drawbacks of the bent pipe with a cleaning port and fundamentally overcomes the above-mentioned situation.
即ち、本考案においては既述した構造の採用か

みに過ぎず、該座盤の厚みをボルトのボール継手
を埋込滑合するに足る厚みにすれば良く、曲げ配
管部からの突出高さを従来の数分の一に抑えるこ

しても突出高さを許容限度内に止めることがで
き、それ自身は蓋の開放時には側転されてしまう
ので、掃除作業時にはベンド管の管壁から座盤の
厚みだけの僅かな立上げ高さになり、従つてベン
ド管内の視野角度が著しく拡大されることとな
り、掃除可能範囲が大巾に拡大され、作業性のよ
い能率的な管内清掃が可能となる。 That is, in the present invention, since the above-mentioned structure is adopted, the opening for fitting the cleaning port cover is only the thickness of the seat, and the thickness of the seat is not enough to fit the ball joint of the bolt. It only needs to be thick enough, and the protrusion height from the bent pipe can be reduced to a fraction of that of conventional pipes. Therefore, even if a tightening mechanism such as an eye nut is used, the protrusion height can be kept within the allowable limit. Since the lid itself is cartwheeled when the lid is opened, the height of the bend pipe is raised from the wall of the bend pipe only by the thickness of the seat during cleaning work, and therefore the viewing angle inside the bend pipe is reduced. As a result, the cleaning area is greatly expanded, and the inside of the pipe can be cleaned efficiently with good workability.
加えて、蓋の開閉、締付密閉作業が容易に行
え、構造的に締付機構が堅牢で強力な蓋締付を可
能とする等の多くの長所を期待できる。 In addition, it can be expected to have many advantages, such as opening/closing the lid, tightening and sealing operations with ease, and having a structurally robust tightening mechanism that enables strong lid tightening.
