【考案の詳細な説明】
本考案は家庭用雑排水路等に介在されて臭気の
逆流等を防止するためのトラツプに関する。[Detailed Description of the Invention] The present invention relates to a trap that is installed in a domestic gray water channel or the like to prevent backflow of odors.
この種のトラツプを形状面から分類すると、そ

に分けられる。これらの中で正確な円孤形をなす
ものは他のものに比べてトラツプに要求される
種々の特性を十分に満足するものとされている。 Classifying this type of trap in terms of shape, there are those whose internal passage is formed in the shape of a precise circular arc, those with a crank-shaped shape, or those with a U-shape in which the curvature of each part is continuously changed. It can be divided into things, etc. Among these, those having an accurate circular arc shape are said to more fully satisfy the various characteristics required for traps than the others.

２の端面に突条４をあらかじめ形成しておき、溝
条３に突条４を嵌め込むとともにそのときの接触
面どうしを接着剤を使用して接着していた。 When molding a trap in which the turning part of the inner passage forms a precise circular arc shape using a synthetic resin such as polyvinyl chloride, the outer wall 1 of the inner passage must be formed at the turning part due to molding technology, especially mold release technology. 2, the outer circumferential portion and the inner circumferential portion are divided and molded separately, and after molding, the outer circumferential portion outer wall 11 and the outer circumferential portion outer wall 1 are formed.
2 are joined together. That is, as shown in detail in FIG.
A protrusion 4 was previously formed on the end face of the groove 2, the protrusion 4 was fitted into the groove 3, and the contact surfaces at that time were bonded together using an adhesive.

することができる。 If such a joint structure is adopted, the contact surfaces 31 and 41 of the groove 3 and the protrusion 4, and the contact surfaces 32 on both sides of the groove 3 and on both sides of the protrusion 4,
42 are bonded to each other via an adhesive, and a relatively large bonding area is ensured, making it possible to maintain strong bonding force and sufficiently satisfactory watertightness.

それがある。また、ひどい場合は外周部分外壁１
１が内周部分外壁１２から脱落するおそれもあ
る。 However, some of the distortion that occurs when piping including traps is constructed may be concentrated in the joints mentioned above, and the adhesive used for joining is often the same as that of the exterior wall 1. For example, if the outer wall 1 is made of polyvinyl chloride, a vinyl-based adhesive is used, so when high-temperature wastewater is poured into the internal passage of the trap, the adhesive softens and the joint strength decreases. However, combined with the concentration of strain mentioned above, there is a risk that the watertightness of the joint may be destroyed. In addition, in severe cases, the outer peripheral part outer wall 1
1 may fall off from the inner peripheral outer wall 12.
本考案は上記事情に鑑みてなされたもので、ト

ことを目的とする。 This invention was developed in view of the above circumstances, and is designed to prevent the watertightness of the joint from being destroyed or falling off even if high-temperature waste water is poured into the internal passage of the trap and the adhesive softens. The purpose is to

の破壊および脱落を確実に防止したものである。 That is, the trap according to the present invention not only uses an adhesive to bond the outer wall of the outer circumference and the outer wall of the inner circumference at the turning part of the internal passageway, but also engages the two outer walls with each other. This reliably prevents watertightness from breaking and falling off.
本考案を実施例について説明する。 The present invention will be described with reference to embodiments.
第３図に例示したトラツプは第１図で説明した

ハにおいて溝条３からの突条４の抜け方向で係合
されている点である。 The trap illustrated in FIG. 3 has the same shape as that explained in FIG. They are joined together with the same joint structure as described. The difference between this trap and the one in Figure 1 is that
The outer wall 11 of the outer circumference and the outer wall 12 of the inner circumference are complicated at three arc-shaped joints (A, B, B) in the illustrated example.
At point C, the protrusions 4 are engaged in the direction in which they are removed from the grooves 3.

３および突条４に溶着されている。 Figure 4 shows the outer wall 11 of the outer periphery and the outer wall 12 of the inner periphery.
This is an example of a specific configuration for engaging the two. That is, in the case shown in the figure, the protrusion 4 fitted into and bonded to the groove 3 and the outer wall 33 of the groove 3 superimposed thereon are spot welded using an appropriate means such as ultrasonic waves, and both are bonded together. A rod-shaped portion 5 extending between the two is formed. This rod-shaped portion 5 is the outer wall 3 of the groove 3.
3 and a part of the protrusion 4 are once melted and then re-hardened to form the outer wall 3.
3 and the protrusion 4.

ら両外壁１１，１２の脱落は起こり得ない。 If this is done, the outer peripheral part outer wall 11 and the inner peripheral part outer wall 12 will be firmly engaged in the direction in which the protrusions 4 come out from the grooves 3, so that the adhesive bonding them will Even if the outer walls 11 and 12 are softened, it is less likely that the outer walls 11 and 12 will be misaligned and the watertightness will be destroyed. For the same reason, both outer walls 11 and 12 cannot fall off.

着剤によつて接着してもよい。 In FIG. 4, the rod-shaped portion 5 is constructed by spot welding, but the invention is not limited to this.
For example, the rod-shaped portion 5 may be formed by driving a wedge-shaped or pin-shaped piece of synthetic resin into a hole previously drilled in the outer wall 33 of the protrusion 4 and the groove 3. It may be adhered to the wall 33 with an adhesive.

は自由である。 FIG. 5 shows a modification. That is, in the case of the same figure, a holding piece 6 for the outer wall 33 of the groove 3 mentioned above is integrally provided on the outside of the protrusion 4 on the inner circumferential outer wall 12, and the engaging claw of this holding piece 6 61 is engaged with the stepped portion 34 of the outer wall 33. This also produces the same effect as explained in FIG. 4. Note that even if the holding piece 6 shown in FIG.
It may be provided partially. Further, it is free to adhere the holding piece 6 to the outer wall 33 of the groove 3 using an adhesive.
上記した実施例では、溝条３が外周部分外壁１
１に形成され、突条４が内周部分外壁１２に形成
されているものを説明したが、溝条が内周部分外
壁に設けられ、突条が外周部分外壁に設けられて
いてもよいことは勿論である。 In the embodiment described above, the groove 3 is the outer peripheral portion of the outer wall 1.
1 and the protrusions 4 are formed on the outer wall 12 of the inner circumferential portion, but the grooves may be provided on the outer wall of the inner circumferential portion and the protrusions may be provided on the outer wall of the outer circumferential portion. Of course.

なる。脱落についても同様である。 As described in detail above, according to the trap of the present invention, even if the adhesive bonding the outer wall and the inner wall softens due to high-temperature wastewater being flushed away, the trap will not damage the outer wall and the inner wall. Since these two outer walls are engaged in the direction in which the protrusion formed on the other end surface comes out from the groove formed on one end surface, it is difficult for the positional relationship between the two outer walls to shift. Destruction of watertightness becomes less likely to occur. The same applies to shedding.
