Description

本発明は、ドレン排水溝の上流側端部にドレンホースの先端部を接続するためのドレンホース接続具に関する。 The present invention relates to a drain hose connector for connecting a leading end portion of a drain hose to an upstream end portion of a drain drain groove.

近年、冷房器や空調器から出るドレン水は、冷房器や空調器から引き出したドレンホースを、屋外のベランダや廊下などの床面に設けたドレン排水溝の上流側端部に接続することによって、ドレン排水溝を通じて排水することが多くなってきた。 In recent years, drain water from air conditioners and air conditioners can be drained by connecting a drain hose drawn from the air conditioner or air conditioner to the upstream end of a drain drainage groove on the floor of an outdoor veranda or corridor. Drainage through drain drains has become increasingly common.

このようにドレンホースをドレン排水溝に接続する接続（連結）具として、ドレンホースの出口端部が差し込まれドレン水をドレン排水溝部材の排水路に向けて流すようになっているホース差込孔部と、ドレン排水溝部材に直接取り付けられドレン排水溝部材の排水路を上方から塞ぐ蓋体を構成する取付部とからなるドレン連結具が提案されている（特許文献１）。このドレン連結具には、ホース差込孔部が一つのものと、大小二つのホース差込孔部を二股状に分岐させて形成したものとがある。
特開２００７−１１３３５５号公報 In this way, as a connection (connection) for connecting the drain hose to the drain drainage groove, the outlet end of the drain hose is inserted, and the drain water flows toward the drainage channel of the drain drainage groove member. There has been proposed a drain connector comprising a hole portion and an attachment portion that is directly attached to the drain drainage groove member and forms a lid that closes the drainage channel of the drain drainage groove member from above (Patent Document 1). This drain connector includes one having a single hose insertion hole and one formed by bifurcating two large and small hose insertion holes.
JP 2007-113355 A

上記特許文献１のドレン連結具のうち、大小二つのホース差込孔部を二股状に分岐させて形成したものは、太いドレンホースでも細いドレンホースでも差し込むことができるという利点を有する反面、大小二つのホース差込孔部が二股状に分岐しているため嵩高となり、スペースの小さい場所での施工には適さないという問題があった。しかも、二股状に分岐した大小二つのホース差込孔部は、ドレンホースの差込み方向が互いに異なり、ドレンホースを２本とも真下方向に差し込むことができないという問題もあった。 Of the drain connector of Patent Document 1, the one formed by bifurcating two large and small hose insertion holes has the advantage that it can be inserted with either a thick drain hose or a thin drain hose, while large and small. Since the two hose insertion holes branch into a bifurcated shape, the hose is bulky and is not suitable for construction in a small space. In addition, the two large and small hose insertion holes branched in a bifurcated manner have a problem in that the drain hoses are inserted in different directions, so that neither of the two drain hoses can be inserted directly downward.

また、上記のドレン連結具は、ホース差込孔部にドレンホースを差し込むだけであるため、ドレンホースがホース差込孔部から抜け出しやすいという問題もあった。 Moreover, since the above drain connector only inserts the drain hose into the hose insertion hole, there is also a problem that the drain hose is easily pulled out from the hose insertion hole.

本発明は、上記の問題に対処すべくなされたもので、その解決しようとする課題は、太いドレンホースでも細いドレンホースでも同じ方向、好ましくは真下方向に差し込むことができ、嵩張らないのでスペースが小さい場所での施工にも有利であり、抜止め部材を取付ければドレンホースの先端部を抜け出さないように固定することもできる、優れたドレンホース接続具を提供することにある。 The present invention has been made to cope with the above-mentioned problems, and the problem to be solved is that a thick drain hose and a thin drain hose can be inserted in the same direction, preferably in the downward direction. An object of the present invention is to provide an excellent drain hose connector which is advantageous for construction in a small place and can be fixed so as not to be pulled out of a drain hose if a retaining member is attached.

上記課題を解決するため、第一の本発明に係るドレンホース接続具｛（１）のタイプ｝は、ドレン排水溝の上流側端部にドレンホースの先端部を接続するためのドレンホース接続具であって、ドレン排水溝の上流側端部に取付けられて該上流側端部の上面開口部を覆う基板部と、この基板部に形成されたドレンホース差込部とから成り、このドレンホース差込部は、太いドレンホースを差し込む内径の大きい大径部と、細いドレンホースを差し込む内径の小さい小径部とが、直列に一体形成されたものであって、ドレンホース差込部の上部が大径部に形成され、下部が小径部に形成されており、ドレンホース差込部の外周面に、ドレンホース抜止め部材を固定するための凸リブ又は凹溝が周設されていて、ドレンホース抜止め部材の内面には、ドレンホースの螺旋状山部を螺入する不連続な螺旋状の溝部が形成されていることを特徴としている。 In order to solve the above-mentioned problem, a drain hose connector {type of (1)} according to the first aspect of the present invention is a drain hose connector for connecting a leading end of a drain hose to an upstream end of a drain drain groove. The drain hose comprises a base plate portion that is attached to the upstream end portion of the drain drainage groove and covers the upper surface opening of the upstream end portion, and a drain hose insertion portion formed in the base plate portion. insertion portion includes a large large diameter portion of the inner diameter to insert a thick drain hose, and a small diameter portion having an inner diameter plugging the narrow drain hose, I der that is integrally formed in series, the top of the drain hose difference write unit Is formed in the large diameter portion, the lower portion is formed in the small diameter portion, and the outer peripheral surface of the drain hose insertion portion is provided with a convex rib or a concave groove for fixing the drain hose retaining member, On the inner surface of the drain hose retaining member It is characterized by discontinuous spiral grooves for screwing the helical ridges of the drain hose is formed.

次に、第二の本発明のドレンホース接続具｛（２）のタイプ｝は、ドレン排水溝の上流側端部にドレンホースの先端部を接続するためのドレンホース接続具であって、ドレン排水溝の上流側端部に取付けられて該上流側端部の上面開口部を覆う基板部と、この基板部に形成されたドレンホース差込部とから成り、このドレンホース差込部は、太いドレンホースを差し込む内径の大きい大径部と、細いドレンホースを差し込む内径の小さい小径部とが、直列に一体形成されたものであって、ドレンホース差込部の上部が小径部に形成され、下部が大径部に形成されると共に、この大径部の上端近傍の外周面に切断用溝部が周設されており、ドレンホース差込部の大径部の外周面と小径部の外周面に、ドレンホース抜止め部材を固定するための凸リブ又は凹溝が周設されていて、ドレンホース抜止め部材の内面には、ドレンホースの螺旋状山部を螺入する不連続な螺旋状の溝部が形成されていることを特徴としている。 Next, the drain hose connector {type (2)} of the second aspect of the present invention is a drain hose connector for connecting the leading end of the drain hose to the upstream end of the drain drain groove, It consists of a substrate part that is attached to the upstream end of the drainage groove and covers the upper surface opening of the upstream end, and a drain hose insertion part formed on this substrate part. A large-diameter portion with a large inner diameter for inserting a thick drain hose and a small-diameter portion with a small inner diameter for inserting a thin drain hose are integrally formed in series, and the upper portion of the drain hose insertion portion is formed in the small-diameter portion. The lower part is formed into a large diameter part, and a cutting groove is provided on the outer peripheral surface near the upper end of the large diameter part, and the outer peripheral surface of the large diameter part and the outer periphery of the small diameter part of the drain hose insertion part. Convex for fixing the drain hose retaining member to the surface And blanking or groove has been circumferentially on the inner surface of the drain hose retaining member, is characterized by discontinuous spiral grooves for screwing the helical ridges of the drain hose is formed.

本発明のドレンホース接続具では、ドレンホース抜止め部材が、開環筒状に形成されていることが望ましい。また、ドレンホース差込部の大径部に対して小径部が内接する位置関係となるように偏心して形成されていることが望ましく、更に、基板部の一端にドレン排水溝の上流側の端面開口部を閉塞する端板部が形成され、他端に接合用の重ね縁部が形成されていることが望ましい。 In the drain hose connector of the present invention, it is desirable that the drain hose retaining member is formed in an open tube shape. The drain hose insertion portion is desirably formed eccentrically so as to be in a positional relationship in which the small diameter portion is inscribed with respect to the large diameter portion of the drain hose insertion portion. It is desirable that an end plate portion for closing the opening portion is formed, and an overlapping edge portion for bonding is formed at the other end.

本発明のドレンホース接続具｛（１）のタイプ及び（２）のタイプ｝のように、ドレンホース差込部が、太いドレンホースを差し込む内径の大きい大径部と、細いドレンホースを差し込む内径の小さい小径部とを、直列に一体形成したものであると、太いドレンホースも細いドレンホースも同じ方向（直列方向）に差し込むことができる。しかも、大径部と小径部を直列に一体形成したドレンホース差込部は、前記特許文献１の二股状に分岐した大小二つのホース差込孔部ほど嵩張らないので、スペースが小さい場所での施工に有利である。 As in the drain hose connector {type (1) and type (2)} of the present invention, the drain hose insertion portion has a large diameter portion into which a thick drain hose is inserted and a large diameter portion into which a thin drain hose is inserted. When the small-diameter portion having a small diameter is integrally formed in series, a thick drain hose and a thin drain hose can be inserted in the same direction (series direction). In addition, the drain hose insertion part in which the large diameter part and the small diameter part are integrally formed in series is not as bulky as the two large and small hose insertion hole parts branched in the bifurcated shape of Patent Document 1, so that the space is small. It is advantageous for construction.

そして、上記（１）のタイプのドレンホース接続具は、ドレンホースが太ければドレンホース差込部の上部の大径部に真下方向に差し込むことができ、ドレンホースが細ければ大径部を通って下部の小径部に真下方向に差し込むことができる。また、ドレンホース差込部の外周面にドレンホース抜止め部材固定用の凸リブ又は凹溝が周設されているので、この凸リブ又は凹溝に太いドレンホースの抜止め部材もしくは細いドレンホースの抜止め部材を取付固定し、ドレンホース差込部の大径部に差し込まれた太いドレンホース、又は、ドレンホース差込部の小径部に差し込まれた細いドレンホースを、上記のドレンホース抜止め部材によって抜け出さないように固定することができる。 The drain hose connector of the above type (1) can be inserted into the large diameter portion at the top of the drain hose insertion portion if the drain hose is thick, and the large diameter portion if the drain hose is thin. It can be inserted in the lower direction through the lower diameter portion. Further, since a convex rib or concave groove for fixing the drain hose retaining member is provided on the outer peripheral surface of the drain hose insertion portion, a thick drain hose retaining member or a thin drain hose is provided in the convex rib or concave groove. The drainage hose is attached to the drain hose insertion part and the thick drain hose inserted into the large diameter part of the drain hose insertion part or the thin drain hose inserted into the small diameter part of the drain hose insertion part. The stopper can be fixed so as not to come out.

一方、上記（２）のタイプのドレンホース接続具は、ドレンホースが細ければドレンホース差込部の上部の小径部に真下方向に差し込むことができ、ドレンホースが細ければ、下部の大径部を切断用溝部で切断して上部の小径部を切除し、下部の大径部にドレンホースを真下方向に差し込むことができる。また、ドレンホース差込部の大径部の外周面と小径部の外周面にドレンホース抜止め部材固定用の凸リブ又は凹溝が周設されているので、細いドレンホースを差し込む場合には、ドレンホース差込部の小径部の凸リブ又は凹溝に細いドレンホースの抜止め部材を取付固定して、ドレンホース差込部の小径部に差し込まれた細いドレンホースを抜け出さないように固定することができ、太いドレンホースを差し込む場合には、小径部を切除したドレンホース差込部の大径部の凸リブ又は凹溝に太いドレンホースの抜止め部材を取付固定して、ドレンホース差込部の大径部に差し込まれた太いドレンホースを抜け出さないように固定することができる。On the other hand, when the drain hose is thin, the drain hose connector of the above type (2) can be inserted into the small diameter part at the upper part of the drain hose insertion part. The diameter portion can be cut with a cutting groove to cut the upper small-diameter portion, and the drain hose can be inserted directly into the lower large-diameter portion. In addition, since a convex rib or groove for fixing the drain hose retaining member is provided around the outer peripheral surface of the large diameter portion and the outer peripheral surface of the small diameter portion of the drain hose insertion portion, when inserting a thin drain hose Install a thin drain hose retaining member on the convex rib or groove in the small diameter part of the drain hose insertion part, and fix the thin drain hose inserted in the small diameter part of the drain hose insertion part so that it does not come out. When inserting a thick drain hose, attach the fixing member of the thick drain hose to the convex rib or concave groove of the large diameter part of the drain hose insertion part with the small diameter part cut, and drain hose The thick drain hose inserted into the large-diameter portion of the insertion portion can be fixed so as not to come out.

更に、ドレンホース差込部の大径部に対して小径部が内接する位置関係となるように偏心して形成されたドレンホース接続具は、その内接部分を家屋外壁面側にしてドレン排水溝の上流側端部に取付けると、ドレンホース差込部に太いドレンホースを差し込んだ場合でも、細いドレンホースを差し込んだ場合でも、家屋外壁面とドレンホースとの間隔を同一にすることができ、大径部に対して小径部が同心的な位置関係にあるものに比べると、細いドレンホースを家屋外壁面に近づけることができる。 Furthermore, the drain hose connector formed eccentrically so as to be in a positional relationship in which the small diameter portion is inscribed with respect to the large diameter portion of the drain hose insertion portion has a drain drainage groove with the inscribed portion being the outdoor wall surface side. If you install it at the upstream end of the drain hose, even if you insert a thick drain hose into the drain hose insertion part, even if you insert a thin drain hose, the space between the outdoor wall surface and the drain hose can be the same, Compared with the case where the small diameter portion is concentric with the large diameter portion, the thin drain hose can be brought closer to the outdoor wall surface.

また、基板部の一端にドレン排水溝の上流側の端面開口部を閉塞する端板部が形成され、他端に接合用の重ね縁部が形成されたドレンホース接続具は、その基板部をドレン排水溝の上流側端部に取付けて上面開口部を覆ったときに、同時に上流側の端面開口部も端板部で閉塞されるため、ドレンホースからドレン排水溝に流入したドレン水がドレン排水溝の上流側の端面開口部から流出するのを防止することができ、しかも、重ね縁部をドレン排水溝の蓋部材の端縁に重ねるだけで、ドレンホース接続具の基板部と蓋部材を隙間なく接合できるので、接合作業が簡単になり施工性が向上する。 In addition, the drain hose connector in which the end plate portion for closing the upstream end face opening of the drain drainage groove is formed at one end of the substrate portion and the overlapping edge portion for joining is formed at the other end is connected to the substrate portion. When it is attached to the upstream end of the drain drainage groove and the upper surface opening is covered, the upstream end surface opening is simultaneously closed by the end plate, so that the drain water flowing from the drain hose into the drain drainage groove is drained. The drain hose connector can be prevented from flowing out from the end face opening on the upstream side of the drainage groove, and only by overlapping the overlapping edge on the edge of the drainage drainage lid member, the substrate portion and the lid member of the drain hose connector Can be joined without gaps, making joining work easier and improving workability.

FIG. 7, FIG. 7 is a cross-sectional view taken along the line GG of FIG. 5, FIGS. 8A and 8B are a plan view and an end view of the drain member of the drain drainage groove, and FIGS. FIG. 9 is a plan view showing another example of use of the drain hose connector with the drain hose omitted, and FIG. 10 is a line HIJK in FIG. It is sectional drawing.

このドレンホース接続具１０は、図１〜図３に示すように、ドレン排水溝の上流側端部に取付けられて該上流側端部の上面開口部を覆う基板部１と、この基板部１の中央に形成された円筒状のドレンホース差込部２とを、熱可塑性合成樹脂にて一体に射出成形したものである。 As shown in FIGS. 1 to 3, the drain hose connector 10 is attached to the upstream end of the drain drainage groove and covers the upper surface opening of the upstream end, and the substrate 1 A cylindrical drain hose insertion portion 2 formed at the center of the tube is integrally injection-molded with a thermoplastic synthetic resin.

図３に示すように、基板部１は偏平なハット形状とされ、その両側端には一段低いフランジ部１ａ，１ａが形成されている。そして、基板部１の表面には、図１に示すように、複数本（３本）の細帯状リブ１ｂが形成されている。この細帯状リブ１ｂは、図８の（ｃ）（ｄ）に示すドレン排水溝の蓋部材３１の表面に形成された細帯状リブ３１ｂに対応して形成されたものであって、基板部１の補強効果と意匠効果が得られるようにしたものである。 As shown in FIG. 3, the board | substrate part 1 is made into the flat hat shape, and the flange parts 1a and 1a one step lower are formed in the both ends. A plurality (three) of strip-like ribs 1b are formed on the surface of the substrate portion 1 as shown in FIG. The strip-like rib 1b is formed corresponding to the strip-like rib 31b formed on the surface of the cover member 31 of the drain drainage groove shown in FIGS. The effect of reinforcement and the design effect can be obtained.

基板部１の一端には、図１、図２、図６に示すように、端板部１ｃが形成されており、後述するようにドレンホース接続具１０をドレン排水溝３（溝部材３２）の上流側端部に取付けると、ドレン排水溝３（溝部材３２）の上流側端部の上面開口部がドレンホース接続具１０の基板部１によって覆われると共に、ドレン排水溝３（溝部材３２）の上流側の端面開口部が端板部１ｃによって閉塞されるようになっている。この実施形態の端板部１ｃは、基板部１の両側のフランジ部１ａ，１ａよりも、ドレン排水溝３の溝部材３２の底板３２ａの厚さ分だけ下方へ突き出すように形成されているが、端板部１ｃの下面とフランジ部１ａ，１ａの下面が面一に揃うように形成してもよい。その場合は、端板部１ｃの下面が溝部材３２の底板３２ａの上面に当接して上流側の端面開口部を閉塞することになるので、図８の（ａ）（ｂ）に示すように溝部材３２の底板３２ａに細溝部３２ｄが形成されているときには、該細溝部３２ｄに嵌まり込む小凸部を端板部１ｃの下面に設けることが好ましい。 As shown in FIGS. 1, 2, and 6, an end plate portion 1 c is formed at one end of the substrate portion 1, and the drain hose connector 10 is connected to the drain drain groove 3 (groove member 32) as will be described later. The upper surface opening of the upstream end of the drain drain groove 3 (groove member 32) is covered by the substrate portion 1 of the drain hose connector 10, and the drain drain groove 3 (groove member 32). ) Upstream end face opening is closed by the end plate 1c. The end plate portion 1c of this embodiment is formed so as to protrude downward by the thickness of the bottom plate 32a of the groove member 32 of the drain drain groove 3 from the flange portions 1a, 1a on both sides of the substrate portion 1. The lower surface of the end plate portion 1c and the lower surfaces of the flange portions 1a and 1a may be formed to be flush with each other. In that case, the lower surface of the end plate portion 1c comes into contact with the upper surface of the bottom plate 32a of the groove member 32 and closes the upstream end surface opening, so as shown in FIGS. When the narrow groove portion 32d is formed on the bottom plate 32a of the groove member 32, it is preferable to provide a small convex portion that fits into the narrow groove portion 32d on the lower surface of the end plate portion 1c.

図１、図２に示すように、基板部１の上記端板部１ｃと反対側端には、一段高い接合用の重ね縁部１ｄが形成されており、図６に示すように、ドレンホース接続具１０をドレン排水溝３（溝部材３２）の上流側端部に取付けるときに、この重ね縁部１ｄをドレン排水溝３の蓋部材３１の端縁部に重ねるだけで、ドレンホース接続具１０と蓋部材３１との接合を簡単に行うことができるようになっている。尚、この重ね縁部１ｄを基板部１の両側面まで形成すると、重ね縁部１ｄが溝部材３２の両側の堤部３２ｃ，３２ｃ［図８の（ｂ）を参照］に当たって、ドレンホース接続具１０をドレン排水溝３（溝部材３２）の上流側端部に取付けることができないため、基板部１の上面のみに重ね縁部１ｃを形成しているが、場合によっては、堤部３２ｃ，３２ｃを覆うように重ね縁部１ｄの両端を延設してもよい。また、この重ね縁部１ｄの下面には、蓋部材３１の細帯状リブ３１ｂが嵌まり込む凹部や、後述するようにドレンホース接続具を連結する際にコーキング剤溜まりとなる凹部を形成してもよい。 As shown in FIG. 1 and FIG. 2, a one-step higher overlapping edge portion 1d is formed at the end of the substrate portion 1 opposite to the end plate portion 1c. As shown in FIG. When the connector 10 is attached to the upstream end of the drain drain groove 3 (groove member 32), the drain hose connector is simply overlapped on the end edge of the lid member 31 of the drain drain groove 3 with the overlapping edge 1d. 10 and the lid member 31 can be easily joined. When the overlapping edge portion 1d is formed up to both side surfaces of the substrate portion 1, the overlapping edge portion 1d hits the bank portions 32c and 32c on both sides of the groove member 32 [see FIG. 10 cannot be attached to the upstream end portion of the drain drain groove 3 (groove member 32), and therefore, the overlapping edge portion 1c is formed only on the upper surface of the substrate portion 1. However, in some cases, the bank portions 32c and 32c are formed. You may extend the both ends of the overlapping edge part 1d so that it may cover. Further, on the lower surface of the overlapping edge portion 1d, a concave portion into which the narrow strip-like rib 31b of the lid member 31 is fitted, or a concave portion that becomes a caulking agent reservoir when connecting the drain hose connector as will be described later, is formed. Also good.

また、基板部１のドレンホース差込部２と端板部１ｃとの間には、後述するようにドレンホース接続具１０を複数連結してドレン排水溝３の上流側端部に取付ける場合に、端板部１ｃを切除しやすくするための薄肉部１ｅが基板部１の全幅に亘って端板部１ｃと平行に形成されている。この薄肉部１ｅは、カッターなどによる切断作業性を向上させる観点から、図１、図２に示すように薄肉部１ｅの全長に亘ってＶ字形もしくはＵ字形の断面を有する溝状に形成することが望ましいが、薄肉部１ｅの両端部（基板部１の両側面からフランジ部１ａに形成された部分）のみをＶ字形もしくはＵ字形の断面を有する溝状に形成してもよい。 Further, when a plurality of drain hose connectors 10 are connected between the drain hose insertion portion 2 and the end plate portion 1c of the substrate portion 1 and attached to the upstream end portion of the drain drain groove 3 as will be described later. A thin portion 1 e for facilitating excision of the end plate portion 1 c is formed in parallel with the end plate portion 1 c over the entire width of the substrate portion 1. This thin portion 1e is formed in a groove shape having a V-shaped or U-shaped cross section over the entire length of the thin portion 1e as shown in FIGS. However, only both end portions of the thin portion 1e (portions formed on the flange portion 1a from both side surfaces of the substrate portion 1) may be formed in a groove shape having a V-shaped or U-shaped cross section.

図１〜図３に示すように、基板部１の中央のドレンホース差込部２は円筒形に形成されており、その上部が、太いドレンホース４を差し込む内径の大きい大径部２ａとなっている。そして、ドレンホース差込部２の下部には、細いドレンホース４０を差し込む小径部２ｂとして内径の小さい内筒部２ｂが大径部２ａと同心的に一体形成されている。 As shown in FIGS. 1 to 3, the drain hose insertion portion 2 at the center of the substrate portion 1 is formed in a cylindrical shape, and the upper portion thereof is a large diameter portion 2 a having a large inner diameter into which the thick drain hose 4 is inserted. ing. An inner cylindrical portion 2b having a small inner diameter is integrally formed concentrically with the large-diameter portion 2a as a small-diameter portion 2b into which the thin drain hose 40 is inserted at the lower portion of the drain hose insertion portion 2.

上記のように、ドレンホース差込部２が大径部２ａと小径部２ｂを上下に直列させて一体形成したものであると、太いドレンホース４も細いドレンホース４０も真下方向に差し込むことができ、しかも、大小二つのホース差込孔部が二股状に分岐したものほど嵩張らないので、スペースの小さい場所で施工する場合に有利である。また、太いドレンホース４を差し込んだときは、該ホースの下端が大径部２ａと小径部２ｂの段差部に当止され、ドレン排水溝３の溝底に当たるまで挿入されることが防止されるので、ドレンホースの下端開口が溝底で閉塞されてドレン水の流入が妨げられる心配をなくすことができる。同様に、小径部２ｂの下端内周面に内鍔部（不図示）を形成すると、細いドレンホース４０の下端が該内鍔部によって当止され、ドレン排水溝３の溝底に当たらなくなるので、ドレン水の流入が妨げられる心配をなくすことができる。 As described above, when the drain hose insertion part 2 is integrally formed by vertically connecting the large diameter part 2a and the small diameter part 2b, the thick drain hose 4 and the thin drain hose 40 can be inserted directly downward. In addition, the two large and small hose insertion holes are not as bulky as the bifurcated one, which is advantageous for construction in a small space. Further, when the thick drain hose 4 is inserted, the lower end of the hose is stopped against the stepped portion of the large diameter portion 2a and the small diameter portion 2b and is prevented from being inserted until it contacts the bottom of the drain drain groove 3. Therefore, it is possible to eliminate the concern that the lower end opening of the drain hose is blocked by the groove bottom and the inflow of drain water is hindered. Similarly, if an inner flange portion (not shown) is formed on the inner peripheral surface of the lower end of the small-diameter portion 2b, the lower end of the thin drain hose 40 is stopped by the inner flange portion and will not contact the groove bottom of the drain drain groove 3. This eliminates the worry that the inflow of drain water is hindered.

ドレンホース接続具１０を取付けるドレン排水溝４は、図８の（ａ）（ｂ）に示すような合成樹脂製の溝部材３２と、図８の（ｃ）（ｄ）に示すような合成樹脂製の蓋部材３１からなるものである。溝部材３２は、縦長の底板３２ａの左右両側に全長に亘って堤部３２ａ，３２ａを形成したものであって、この堤部３２ａ，３２ａの相対向する内側面の下端には、蓋部材３１の左右両側のフランジ部３１ａ，３１ａを挿入する凹条３２ｂ，３２ｂが形成されており、また、底板３２ａの上面には、少量のドレン水でもスムーズに流れるように、多数の細溝部３２ｄが形成されている。一方、蓋部材３１は、ドレンホース接続具１０の基板部１と同様の偏平なハット形状の断面を有するもので、左右両側には一段低いフランジ部３１ａ，３１ａが形成されており、上面には補強効果、意匠効果、排水効果等を発揮する３本の細帯状リブ３１ｂが形成されている。そして、蓋部材３１の裏面には、耐荷重を向上させるための３つの支持片３１ｃが形成されている。 The drain drain groove 4 to which the drain hose connector 10 is attached includes a synthetic resin groove member 32 as shown in FIGS. 8A and 8B and a synthetic resin as shown in FIGS. 8C and 8D. The lid member 31 is made of a metal. The groove member 32 is formed by forming the bank portions 32a, 32a over the entire length on both the left and right sides of the vertically long bottom plate 32a, and the lid member 31 is provided at the lower end of the opposite inner side surfaces of the bank portions 32a, 32a. Grooves 32b and 32b for inserting the left and right flange portions 31a and 31a are formed, and a large number of narrow groove portions 32d are formed on the upper surface of the bottom plate 32a so that even a small amount of drain water flows smoothly. Has been. On the other hand, the lid member 31 has a flat hat-shaped cross section similar to that of the substrate portion 1 of the drain hose connector 10, and is formed with lower flange portions 31a and 31a on the left and right sides, and on the upper surface. Three narrow strip-shaped ribs 31b that exhibit a reinforcing effect, a design effect, a drainage effect, and the like are formed. And on the back surface of the lid member 31, three support pieces 31c for improving the load resistance are formed.

次に、上記のドレンホース接続具１０、溝部材３２、蓋部材３１を用いて、図４に示すようなドレン排水設備を屋外のベランダ等に施工する場合について説明する。 Next, the case where drain drainage equipment as shown in FIG. 4 is constructed on an outdoor veranda or the like using the drain hose connector 10, the groove member 32, and the lid member 31 will be described.

まず、上記溝部材３２の凹条３２ｂ，３２ｂに上記蓋部材３１のフランジ部３１ａ，３１ａを挿入し、ドレンホース接続具１０が取付けられる上流側端部を残して、溝部材３２の上面開口部（両側の堤部３２ｃ，３２ｃの相互間の開口部）を蓋部材３１で覆うことにより、ドレン排水溝３を組み立てる。次いで、ドレン排水溝３（溝部材３２）の上流側端部の凹条３２ｂ，３２ｂに、ドレンホース接続具１０のフランジ部１ａ，１ａを挿入することによって、図５〜図７に示すようにドレンホース接続具１０を溝部材３２の上流側端部に取付け、ドレンホース接続具１０の基板部１で溝部材３２の上流側端部の上面開口部を覆うと共に、ドレンホース接続具１０の端板部１ｃで溝部材３２の上流側の端面開口部を閉塞する。そして、図６に示すように、ドレンホース接続具１０の重ね縁部１ｄを蓋部材３１の端縁に重ねて、ドレンホース接続具１０と蓋部材３１を接合し、このドレンホース接続具１０を取付けたドレン排水溝３を、図４，図６に示すようにベランダ床面５の片側の一辺沿いに敷設して、ドレン排水溝３の下流側の端面開口部をベランダの排水溝５ａに臨ませる。そして、図４、図６、図７に示すように屋内の冷房機や空調器から引き出した細いドレンホース４０の先端をドレンホース接続具１０のドレンホース差込部２の小径部２ｂに差し込むか、又は、仮想線で示すように太いドレンホース４をドレンホース差込部２の大径部２ａに差し込んで、ドレン排水設備の施工を完了する。 First, the flanges 31a and 31a of the lid member 31 are inserted into the recesses 32b and 32b of the groove member 32, and the upper end opening of the groove member 32 is left, leaving the upstream end to which the drain hose connector 10 is attached. The drain drainage groove 3 is assembled by covering the opening portion between the bank portions 32c and 32c on both sides with the lid member 31. Next, as shown in FIGS. 5 to 7, by inserting the flange portions 1 a and 1 a of the drain hose connector 10 into the recesses 32 b and 32 b at the upstream end of the drain drain groove 3 (groove member 32). The drain hose connector 10 is attached to the upstream end of the groove member 32, the upper surface opening of the upstream end of the groove member 32 is covered with the substrate portion 1 of the drain hose connector 10, and the end of the drain hose connector 10 The end surface opening on the upstream side of the groove member 32 is closed by the plate portion 1c. Then, as shown in FIG. 6, the overlapping edge portion 1 d of the drain hose connector 10 is overlapped with the end edge of the lid member 31, the drain hose connector 10 and the lid member 31 are joined, and the drain hose connector 10 is connected to the drain hose connector 10. The drain drainage groove 3 attached is laid along one side of the veranda floor surface 5 as shown in FIGS. 4 and 6, and the downstream end face opening of the drainage drainage groove 3 faces the drainage groove 5a of the veranda. I will. Then, as shown in FIGS. 4, 6, and 7, the tip of the thin drain hose 40 drawn from the indoor air conditioner or air conditioner is inserted into the small diameter part 2 b of the drain hose insertion part 2 of the drain hose connector 10. Alternatively, as shown by the phantom line, the thick drain hose 4 is inserted into the large diameter portion 2a of the drain hose insertion portion 2 to complete the construction of the drain drainage facility.

尚、ドレンホース接続具１０の端板部１ｃと溝部材３２の上流側の端面は接着剤等で水密的に接着することが望ましく、また、ドレンホース接続具１０の端板部１ｃと家屋外壁面７との間にはコーキング剤等を詰めることが望ましい。 The end plate 1c of the drain hose connector 10 and the upstream end surface of the groove member 32 are desirably water-tightly bonded with an adhesive or the like, and the end plate 1c of the drain hose connector 10 and the outdoor side of the house. It is desirable to pack a caulking agent between the wall surfaces 7.

上記のように本発明のドレンホース接続具１０を用いて施工すると、太いドレンホース４でも細いドレンホース４０でも差込み接続することができ、しかも、ドレンホース差込部２が円筒形で嵩張らないため、図４に示すようにベランダのスペースの小さい片隅においてドレン排水溝３の上流側端部にドレンホース接続具１０を取付けるような場合に施工がし易くなる利点がある。また、ドレン排水溝３（溝部材３２）の上流側の端面開口部がドレンホース接続具１０の端板部１ｃで閉塞されるため、ドレンホース４又は４０から流入したドレン水はドレン排水溝３（溝部材３２）の端面開口部から流出することなく、ドレン排水溝３を下流側に流れてベランダの排水溝５ａへ排水される。その場合、ドレン水が少量でも、溝部材３２の細溝３２ｄをスムーズに流れて排水される。また、ドレンホース接続具１０の重ね縁部１ｄを蓋部材３１の端縁に重ねるだけで簡単に接合できるので、この点からも施工性が向上する。 When constructed using the drain hose connector 10 of the present invention as described above, either the thick drain hose 4 or the thin drain hose 40 can be inserted and connected, and the drain hose insertion portion 2 is cylindrical and not bulky. As shown in FIG. 4, when the drain hose connector 10 is attached to the upstream end portion of the drain drain groove 3 at one corner of the veranda having a small space, there is an advantage that the construction becomes easy. In addition, since the upstream end face opening of the drain drain groove 3 (groove member 32) is closed by the end plate 1c of the drain hose connector 10, the drain water flowing in from the drain hose 4 or 40 is drain drain groove 3. Without flowing out from the end surface opening of (groove member 32), it flows through drain drainage groove 3 downstream and drains into drainage groove 5a of the veranda. In that case, even if the drain water is small, it flows smoothly through the narrow groove 32d of the groove member 32 and is drained. Moreover, since it can join simply by overlapping the overlap edge part 1d of the drain hose connector 10 on the edge of the cover member 31, workability improves also from this point.

上記の施工例は、ドレン排水溝３にドレンホース接続具１０を一つだけ取付けたものであるが、例えば太いドレンホース４と細いドレンホース４０が２本引き出されているような場合には、二つのドレンホース接続具１０を連結してドレン排水溝３の上流側端部に取付ける必要がある。そのような場合は、二番目のドレンホース接続具１０の基板部１を、Ｖ字形の断面を有する溝状の薄肉部１ｅ沿いにカッター等で切断して端板部２を切除し、図９、図１０に示すように、この二番目のドレンホース接続具１０の基板部１の切断端部に、一番目のドレンホース接続具１０の重ね縁部１ｄを重ねて、双方のドレンホース接続具１０，１０を連結すると共に、二番目のドレンホース接続具１０の重ね縁部１ｄをドレン排水溝３の蓋部材３１の端縁部に重ねて接合し、一方のドレンホース接続具１０のドレンホース差込部２の大径部２ａに太いドレンホース４を、また、他方のドレンホース接続具１０のドレンホース差込部２の小径部２ｂに細いドレンホース４０を、それぞれ差し込んで接続すればよい。このようにドレンホース接続具１０を複数連結する場合、前述したように接合用の重ね縁部１ｄの下面にコーキング剤溜まりとなる凹部が形成されていると、コーキング剤を詰めて水密的に連結することができる。 In the above construction example, only one drain hose connector 10 is attached to the drain drainage groove 3. For example, when two thick drain hoses 4 and two thin drain hoses 40 are pulled out, It is necessary to connect the two drain hose connectors 10 and attach them to the upstream end of the drain drain groove 3. In such a case, the substrate portion 1 of the second drain hose connector 10 is cut with a cutter or the like along the groove-like thin portion 1e having a V-shaped cross section, and the end plate portion 2 is cut away. As shown in FIG. 10, the overlapping edge portion 1 d of the first drain hose connector 10 is overlapped with the cut end portion of the substrate portion 1 of the second drain hose connector 10, and both drain hose connectors are connected. 10 and 10, the overlapping edge 1 d of the second drain hose connector 10 is overlapped and joined to the end edge of the lid member 31 of the drain drain groove 3, and the drain hose of one drain hose connector 10 is joined. A thick drain hose 4 may be inserted into and connected to the large diameter portion 2a of the insertion portion 2 and a thin drain hose 40 may be inserted into the small diameter portion 2b of the drain hose insertion portion 2 of the other drain hose connector 10 respectively. . When a plurality of drain hose connection devices 10 are connected in this way, as described above, when a concave portion serving as a caulking agent pool is formed on the lower surface of the overlapping edge portion 1d for joining, the caulking agent is packed and watertightly connected. can do.

更に、３本以上のドレンホースが引き出されている場合は、二番目以降のドレンホース接続具１０の端板部１ｃを全て切除し、上記と同様に連結して３個以上のドレンホース接続具１０をドレン排水溝３に取付け、それぞれのドレンホース接続具１０のドレンホース差込部２の大径部２ａ又は小径部２ｂに、太いドレンホース４又は細いドレンホース４０を１本ずつ差し込んで接続すればよい。 Furthermore, when three or more drain hoses are pulled out, all the end plate portions 1c of the second and subsequent drain hose connectors 10 are cut out and connected in the same manner as described above to connect three or more drain hose connectors. 10 is attached to the drain drainage groove 3, and one large drain hose 4 or one thin drain hose 40 is inserted into the large diameter portion 2a or the small diameter portion 2b of the drain hose insertion portion 2 of each drain hose connector 10 and connected. do it.

The substrate member 1 is attached to the upstream end of the groove member 32 and the lid member 31 of the drain drain groove 3 is joined with an adhesive or the like, and the upstream end surface opening of the groove member 32 is a caulking agent. And is blocked by a sealing agent. Then, the drain hose retaining member 7 or 71 indicated by the phantom line in FIG. 16 is connected so that the thick drain hose 4 or the thin drain hose 40 does not come out in the following manner. In addition, the drain hose retaining members 7 and 71 are formed integrally with the large-diameter cylindrical portions 7a and 71a and the small-diameter cylindrical portions 7b and 71b as well as the inner surfaces of the large-diameter cylindrical portions 7a and 71a. A concave groove into which the convex rib 2c is fitted is formed, and a discontinuous spiral groove portion into which the spiral peaks 4a and 40a of the drain hoses 4 and 40 are screwed is formed on the inner surfaces of the small diameter cylindrical portions 7b and 71b. Is.

まず、細いコルゲート管からなるドレンホース４０を接続する場合は、図１６に仮想線で示すように、細いドレンホース４０をドレンホース抜止め部材７１の小径筒部７１ｂにねじ込み、細いドレンホース４０の先端部をドレンホース差込部２の小径部２ｂに挿入しながら、ドレンホース抜止め部材７１の大径筒部７１ａを少し弾性拡開してドレンホース差込部２の小径部２ｂに外嵌合させ、小径部２ｂの外周面の凸リブ２ｃ，２ｃを大径筒部７１ａの凹溝に嵌め込んで、細いドレンホース４０を抜け出さないように固定する。 First, when connecting the drain hose 40 made of a thin corrugated pipe, the thin drain hose 40 is screwed into the small diameter cylindrical portion 71b of the drain hose retaining member 71 as shown by the phantom line in FIG. While inserting the distal end portion into the small diameter portion 2b of the drain hose insertion portion 2, the large diameter cylindrical portion 71a of the drain hose retaining member 71 is slightly elastically expanded to fit the small diameter portion 2b of the drain hose insertion portion 2. Then, the convex ribs 2c, 2c on the outer peripheral surface of the small diameter portion 2b are fitted into the concave grooves of the large diameter cylindrical portion 71a, and the thin drain hose 40 is fixed so as not to come out.

一方、太いコルゲート管からなるドレンホース４を接続する場合は、予め、ドレンホース差込部２を切断用溝部２ｄに沿って切断することにより、図１７に示すように小径筒部を切除する。そして、図１７に仮想線で示すように、太いドレンホース４をドレンホース抜止め部材７の小径筒部７ｂにねじ込み、太いドレンホース４の先端部をドレンホース差込部２の大径部２ａに挿入しながら、ドレンホース抜止め部材７の大径筒部７ａを少し弾性拡開してドレンホース差込部２の大径部２ａに外嵌合させ、大径部２ａの外周面の凸リブ２ｃ，２ｃを大径筒部７ａの凹溝に嵌め込んで、太いドレンホース４を抜け出さないように固定する。 On the other hand, when connecting the drain hose 4 made of a thick corrugated tube, the drain hose insertion part 2 is cut in advance along the cutting groove 2d, so that the small-diameter cylindrical part is cut as shown in FIG. Then, as shown by phantom lines in FIG. 17, the thick drain hose 4 is screwed into the small diameter cylindrical portion 7 b of the drain hose retaining member 7, and the distal end portion of the thick drain hose 4 is the large diameter portion 2 a of the drain hose insertion portion 2. The large-diameter cylindrical portion 7a of the drain hose retaining member 7 is slightly elastically expanded while being inserted into the large-diameter portion 2a of the drain hose insertion portion 2, and the outer peripheral surface of the large-diameter portion 2a is convex. The ribs 2c and 2c are fitted into the concave grooves of the large-diameter cylindrical portion 7a to fix the thick drain hose 4 so as not to come out.

このドレンホース接続具１３の他の構成及び作用効果は、前述のドレンホース接続具１０と同様であるので、図１６，図１７において、同一部分に同一符号を付し、重複説明を省略する。尚、このドレンホース接続具１３では、ドレンホース差込部２の大径部２ａと小径部２ｂの外周面に凸リブ２ｃ，２ｃを２本ずつ形成し、ドレンホース抜止め部材７，７１の大径筒部７ａ，７１ａの内面に２つの凹溝を形成しているが、凸リブ２ｃと凹溝の数は１つでも３つ以上でもよく、また、ドレンホース差込部２の大径部２ａと小径部２ｂの外周面に凹溝を形成し、大径筒部７ａ，７１ａの内面に凸リブを形成するようにしても勿論よい。また、
ドレンホース４，４０が、リング状の山部と谷部を交互に連成したコルゲート管からなる場合は、ドレンホース抜止め部材７，７１の小径筒部７ｂ，７１ｂの内面に、不連続な螺旋状溝部に替えて開環状の溝部を形成し、小径筒部７ｂ，７１ｂを少し弾性拡開してドレンホース４，４０に外嵌着させることにより、ドレンホース４，４０のリング状山部を小径筒部７ｂ，７１ｂの開環状溝部に嵌め込んで抜けないようにドレンホース４，４０を取付ければよい。 Since other configurations and operational effects of the drain hose connector 13 are the same as those of the drain hose connector 10 described above, the same reference numerals are given to the same parts in FIGS.
