【考案の詳細な説明】本考案はトラップ本体へのストレーナ−の着脱を容易且
つ確実にせしめる様にした排水トラップに関するもので
ある。[Detailed Description of the Invention] The present invention relates to a drainage trap that allows a strainer to be easily and reliably attached to and removed from the trap body.

従来、この種のトラップとして螺子方式及び嵌合方式に
てストレーナ−をトラップ本体に締結せしめたものが見
受けられるが、かかる方式にて両者を締結せしめると、
螺子溝部及び嵌合部間に砂及び粉塵等が介入し、トラッ
プ本体内部の掃除の際に上記ストレーナ−の取り外しに
困難性を有する等の欠点を有せしめていた。Conventionally, this type of trap has been seen in which the strainer is fastened to the trap body using a screw method or a fitting method, but when the two are fastened using such a method,
Sand, dust, etc. get in between the threaded groove and the fitting part, resulting in drawbacks such as difficulty in removing the strainer when cleaning the inside of the trap body.

本願は上記欠点に鑑み、排水口筒周壁に溝を設けると共

実施の一例を図面に基いて説明すると、１はトラップ本体であって、底部中央に内周壁を上方へ
拡開する排水口筒２を形成し、該排水口筒２を形成し、
該排水口筒２の内周壁略中央位置に凹状の溝部３を周設
せしめている。In view of the above-mentioned drawbacks, the present application attempts to eliminate the above-mentioned drawbacks by providing a groove on the peripheral wall of the drain port cylinder and providing a protrusion that engages with the groove on the arm hanging down from the bell. An example will be explained based on the drawings. Reference numeral 1 denotes a trap body, in which a drain port tube 2 is formed in the center of the bottom portion to expand the inner circumferential wall upward;
A concave groove 3 is provided approximately at the center of the inner peripheral wall of the drain pipe 2.

角部１１．１１’を形成している。Reference numeral 4 denotes a strainer that is locked to an annular step 6 formed in the upper opening 5 of the trap body 1, and a bell 8 made of an elastic material such as plastics is attached to the lower part of the strainer, which is fastened with a bolt 7. At the same time, the pair of arms 9 and 9' are made to hang down from the lower part of the bell 8 to form a 0-shaped protrusion 10 and 10' that protrudes outward at the tips of the arms 9 and 9'. The distal end is made narrower than the outer side to form an acute angle portion 11.11' at the distal end.

尚、腕部９，９′の基部１２．１２’外側は排水口筒２
の内周壁延線上に位置せしめ、又突起部１０．１０’は

成せられている。In addition, the outside of the base 12 and 12' of the arms 9 and 9' is the drain pipe 2.
The projections 10 and 10' are formed at positions where they fit into the grooves 3 of the drain pipe 2 when the strainer 4 is engaged with the annular step 6 of the trap body 1. I am forced to do so.

ラスチックス等の弾性部材より形成せられているので、
上方に拡開する排水口筒２の上方開口部より先端鋭角状
の腕部９，９′を挿入すれば、腕部９，９′は内方へ屈
撓しながら下方へ進み、排水口筒２内周壁に周設した溝
部３へ突起部１０．１０’を案内するのである。According to the structure of the embodiment of the present invention, since the arm portions 9°9' are made of an elastic member such as plastic,
When the arms 9, 9', each having an acute angle at the tip, are inserted into the upper opening of the drain pipe 2, which expands upward, the arms 9, 9' move downward while bending inward, and 2. The protrusion 10.10' is guided into the groove 3 provided around the inner circumferential wall.

要するに本考案はトラップ本体１の排水口筒２周壁に溝

で、ストレーナー４のトラップ本体１への取付は取外し
は容易且つ確実になるのである。In short, the present invention forms a groove 3 in the circumferential wall of the drain pipe 2 of the trap body 1, and attaches a bell 8 made of an elastic member to the lower part of the strainer 4, and the bell 8 has a protrusion 10.1.
Since the arm portions 9.9' forming the 0' are made to hang down, and the protrusions 10.10' are fitted into the groove 3, the strainer 4 can be attached to the trap body 1 without having to be removed. It becomes easy and reliable.

′は排水口筒２内周壁土をスライドするのである。In addition, the inner circumferential wall of the drain pipe 2 is expanded upward, and the distal ends of the arms 9 and 9' are made narrower than the outer sides.
, 9' together with the elasticity of the arms 9, 9', the arms 9, 9 can be easily and smoothly moved.
' slides on the inner wall soil of the drain pipe 2.

一方溝部３を排水口筒２内周壁上に周設せしめたので、
溝部３に対して円周方向上如何なる位置からも腕部９，
９′が挿入出来る等その実用的効果甚だ大なるものであ
る。On the other hand, since the groove portion 3 is provided around the inner circumferential wall of the drain pipe 2,
The arm portion 9 can be viewed from any position in the circumferential direction with respect to the groove portion 3.
9' can be inserted, and its practical effects are enormous.
