Description

本発明は、軒樋の底部に取り付けられる自在ドレンに関する。   The present invention relates to a universal drain attached to the bottom of an eaves bowl.

軒樋用の自在ドレンとして、ねじ込み方式のものが使用されている。この自在ドレンは、外周面に雄ねじが設けられた円筒の上縁外周にフランジが設けられた内円筒体と、内周面に雌ねじが設けられた円筒の上縁外周にフランジが設けられた外円筒体とからなり、前記内円筒体の雄ねじに前記外円筒体の雌ねじをねじ込むようにしたものである（例えば、特許文献１参照。）。   As a free drain for eaves, a screw type is used. This universal drain is composed of an inner cylindrical body having a flange provided on the outer periphery of a cylinder having a male thread on the outer peripheral surface, and an outer cylinder having a flange provided on the outer periphery of the upper edge of the cylinder having an inner peripheral surface provided with a female screw. A cylindrical body is formed, and a female screw of the outer cylindrical body is screwed into a male thread of the inner cylindrical body (see, for example, Patent Document 1).

この自在ドレンを軒樋の底部に取り付けるには、軒樋の底部に設けられた取付孔に、軒樋の上方から内円筒体を挿入し、この内円筒体の雄ねじに軒樋の下方から外円筒体の雌ねじをねじ込むことにより、自在ドレンが軒樋の底部に取り付けられる。
実用新案登録第２６０１３７６号公報 In order to attach this free drain to the bottom of the eaves bowl, insert the inner cylindrical body from the upper side of the eaves bowl into the mounting hole provided in the bottom of the eaves bowl, and remove it from the lower side of the eaves bowl to the male screw of this inner cylinder body. The free drain is attached to the bottom of the eaves by screwing the cylindrical female screw.
Utility Model Registration No. 2601376

しかしながら特許文献１に記載された自在ドレンの場合、軒樋の底部のドレン取り付け位置に取付孔を設け、軒樋の上方から内円筒体を取付孔に装着し、次いで、軒樋の下方から外円筒体を止め付ける作業となっている。通常、軒樋は高所に取り付けられるから、上記の作業は高所作業となり危険が伴う。更に、軒樋が前高とされて化粧されていたり、水切り段差が設けられたりしている場合は、軒樋の前面を越して、その上から排水孔に内円筒体を取り付けなければならず、直接排水孔を見ながら内円筒体を排水孔に挿入し難いために、この作業は益々困難なものになっているのみならず、挿入した内円筒体のフランジを押さえながら、外円筒体をねじ込むことも難しいものであった。   However, in the case of the universal drain described in Patent Document 1, a mounting hole is provided at the drain mounting position at the bottom of the eaves bowl, the inner cylindrical body is attached to the mounting hole from above the eaves bowl, and then the outer side is removed from the lower side of the eaves bowl. The work is to fix the cylinder. Usually, since the eaves is attached to a high place, the above work becomes a high place work and is dangerous. Furthermore, if the eaves is made with a front height, or if there is a draining step, the inner cylinder must be attached to the drainage hole from above the eaves. This work is not only difficult because it is difficult to insert the inner cylinder into the drain hole while looking directly at the drain hole, but also the outer cylinder is pressed while holding the flange of the inserted inner cylinder. It was also difficult to screw in.

本発明の目的は、内円筒体を軒樋の下方から取り付けることができる自在ドレンを提供することである   An object of the present invention is to provide a universal drain capable of attaching an inner cylindrical body from below the eaves.

請求項１記載の発明は、外周面に雄ねじが設けられた円筒の上縁外周にフランジが設けられた内円筒体と、内周面に雌ねじが設けられた円筒の上縁外周にフランジが設けられた外円筒体とからなり、前記内円筒体の雄ねじに前記外円筒体の雌ねじをねじ込み、両円筒体のフランジ間にて軒樋の底部に形成された排水孔の周縁部を挟持するようにした自在ドレンにおいて、前記内円筒体のフランジに、外周縁から円筒側に向かって切り欠き溝が設けられていることを特徴とする。   According to the first aspect of the present invention, there is provided an inner cylindrical body having a flange provided on the outer periphery of a cylinder having a male screw provided on the outer peripheral surface, and a flange provided on the outer periphery of the cylinder having a female screw provided on the inner peripheral surface. The outer cylindrical body is screwed with the female thread of the outer cylindrical body into the male thread of the inner cylindrical body, and the peripheral edge portion of the drainage hole formed at the bottom of the eaves is sandwiched between the flanges of both cylindrical bodies. In the universal drain, the notch groove is provided in the flange of the inner cylindrical body from the outer peripheral edge toward the cylinder side.

請求項２記載の発明は、請求項１記載の自在ドレンにおいて、外円筒体のフランジ外径が内円筒体のフランジ外径よりも大きくされていることを特徴とする。   The invention according to claim 2 is the universal drain according to claim 1, wherein the outer diameter of the flange of the outer cylindrical body is larger than the outer diameter of the flange of the inner cylindrical body.

本発明の自在ドレンが適用される軒樋の材質は、軒樋の底面が平面状であれば、合成樹脂、金属のどちらでもよい。   The material of the eaves to which the universal drain of the present invention is applied may be either synthetic resin or metal as long as the bottom surface of the eaves is flat.

本発明における自在ドレンを構成している内円筒体および外円筒体の材質は、合成樹脂、金属のどちらでもよい。   The material of the inner cylinder and the outer cylinder constituting the universal drain in the present invention may be either synthetic resin or metal.

内円筒体のフランジには、その外周縁から円筒側にわたって切り欠き溝が設けられている。この切り欠き溝が存在していることで、軒樋の底部に形成された排水孔の周縁部に同様に設けられる切り欠き溝を利用して、軒樋の下方から内円筒体のフランジを軒樋内に差し込むことができる。フランジの厚みや幅はフランジの弾性変形を妨げないように決めればよい。   A notch groove is provided in the flange of the inner cylinder from the outer peripheral edge to the cylinder side. The presence of this notch groove allows the inner cylindrical flange to be connected to the eaves from the lower side of the eaves by using a notch groove provided in the peripheral edge of the drainage hole formed at the bottom of the eaves. Can be inserted into the cage. The thickness and width of the flange may be determined so as not to hinder the elastic deformation of the flange.

また、フランジの切り欠き溝の切り欠き方向は、フランジの外周縁の一点から、円筒の中心に向かう方向ないし円筒の外周面への接線方向の間に位置する向きにすればよい。なお、接線に近い方向に設けると、自在ドレンの取付作業を楽に行える。   Further, the notch direction of the notch groove of the flange may be a direction located from one point on the outer peripheral edge of the flange to the direction toward the center of the cylinder or the tangential direction to the outer peripheral surface of the cylinder. In addition, if it is provided in the direction close to the tangent, the mounting operation of the free drain can be performed easily.

切り欠き溝の長さは、内円筒体の円筒の外径および軒樋の底部に形成される排水孔の内径に応じて決めればよい。切り欠き溝は直線状でも曲線状でもよい。   The length of the cutout groove may be determined according to the outer diameter of the cylinder of the inner cylindrical body and the inner diameter of the drain hole formed in the bottom of the eaves bowl. The notch groove may be linear or curved.

なお、外円筒体のフランジ外径を内円筒体のフランジ外径よりも大きくすることで、軒樋側に設けた切り欠き溝が外円筒体のフランジにて覆われて見えず、自在ドレンの取り付け後の下方からの見栄えがよい。   In addition, by making the outer diameter of the flange of the outer cylinder larger than the outer diameter of the flange of the inner cylinder, the notch groove provided on the eaves side is not covered with the flange of the outer cylinder and cannot be seen. It looks good from below after installation.

軒樋側の切り欠き溝は、軒樋の底部に形成した排水孔の内周縁の一点から外方向に設ければよい。切り欠き溝の形状は直線状あるいは曲線状でもよい。その長さは、排水孔と同心で内円筒体のフランジの外径と同じ大きさの仮想円の円周位置以上とすればよい。このようにすれば、内円筒体フランジを軒樋側の切り欠き溝の奥まで完全に差し込んだ時に、内円筒体の円筒と排水孔とを略同心とすることができる。   The cutout groove on the eaves side may be provided outward from one point on the inner periphery of the drain hole formed in the bottom of the eaves. The shape of the cutout groove may be linear or curved. The length should just be more than the circumference position of the virtual circle which is concentric with the drain hole and has the same size as the outer diameter of the flange of the inner cylindrical body. If it does in this way, when the inner cylinder flange is completely inserted into the notch groove on the eaves side, the cylinder of the inner cylinder and the drain hole can be made substantially concentric.

請求項１記載の発明においては、内円筒体のフランジに、外周縁から円筒側に向かって切り欠き溝が設けられているので、軒樋の底部に形成された排水孔の周縁部にフランジと同様の切り欠き溝を設け、この両者の切り欠き溝を利用して、軒樋の下方から内円筒体を取り付けることができる。   In the first aspect of the present invention, since the notch groove is provided in the flange of the inner cylindrical body from the outer peripheral edge toward the cylinder side, the flange and the peripheral edge of the drainage hole formed in the bottom of the eaves A similar notch groove is provided, and the inner cylindrical body can be attached from below the eaves by using the notch grooves of both.

請求項２記載の発明においては、外円筒体のフランジ外径が内円筒体のフランジ外径よりも大きくされているので、軒樋側に設ける切り欠き溝は外円筒体のフランジにて覆われる。このため、自在ドレン取付後に、軒樋側の切り欠き溝が地表側から見えず、軒先の外観の見栄えがよい。   In the invention described in claim 2, since the outer diameter of the flange of the outer cylindrical body is larger than the outer diameter of the flange of the inner cylindrical body, the notch groove provided on the eaves side is covered with the flange of the outer cylindrical body. . For this reason, after mounting the free drain, the cutout groove on the eaves side is not visible from the ground surface side, and the appearance of the eaves is good.

次に、本発明の自在ドレンを図面を参照して説明する。
図１は本発明の自在ドレンの一例を示す半縦断面図である。図２は図１の内円筒体の一例を示す平面図である。 Next, the universal drain of the present invention will be described with reference to the drawings.
FIG. 1 is a half vertical sectional view showing an example of a universal drain according to the present invention. FIG. 2 is a plan view showing an example of the inner cylindrical body of FIG.

図１に示すように、自在ドレン１は内円筒体２と外円筒体３とからなっている。内円筒体２は、円筒２１の外周面２１１に雄ねじを有し、かつ、円筒２１の一端に外向きにフランジ２２が設けられている。外円筒体３は、円筒３１の内周面３１１に雌ねじを有し、かつ、円筒３１の一端に外向きにフランジ３２が設けられている。雄ねじと雌ねじは互いに螺合するようになっている。内円筒体２および外円筒体３はともに硬質塩化ビニル樹脂製のものである。   As shown in FIG. 1, the universal drain 1 includes an inner cylindrical body 2 and an outer cylindrical body 3. The inner cylindrical body 2 has a male screw on the outer peripheral surface 211 of the cylinder 21, and a flange 22 is provided outwardly at one end of the cylinder 21. The outer cylindrical body 3 has a female thread on the inner peripheral surface 311 of the cylinder 31, and a flange 32 is provided outwardly at one end of the cylinder 31. The male screw and the female screw are screwed together. Both the inner cylindrical body 2 and the outer cylindrical body 3 are made of hard vinyl chloride resin.

図２に示すように、内円筒体２のフランジ２２には、その外周縁部２２１の一点から円筒２１の中心に向かって、直線状の切り欠き溝２３がフランジ２２幅全長にわたって設けられている。この切り欠き溝２３の幅ａ１は、後述する軒樋４の底部４１の厚みｔ２より少し大きくされている。   As shown in FIG. 2, the flange 22 of the inner cylindrical body 2 is provided with a linear notch groove 23 over the entire length of the flange 22 from one point of the outer peripheral edge 221 toward the center of the cylinder 21. . The width a1 of the cutout groove 23 is set to be slightly larger than the thickness t2 of the bottom 41 of the eaves ridge 4 described later.

なお、切り欠き溝２３の方向は、図３に示すように、円筒２１の円周の接線方向であっても良い。また、切り欠き溝２３は、円筒２１側が狭く、フランジ２２の外周部に向かって徐々に広くされていると、自在ドレン１を軒樋４の底部４１に取り付ける際に、内円筒体２のフランジ２２の回転をより容易に行える。   The direction of the cutout groove 23 may be a tangential direction of the circumference of the cylinder 21 as shown in FIG. Further, when the cutout groove 23 is narrow on the cylinder 21 side and is gradually widened toward the outer periphery of the flange 22, the flange of the inner cylinder 2 is attached when the universal drain 1 is attached to the bottom 41 of the eaves 4. The rotation of 22 can be performed more easily.

フランジ切り欠き溝２３の側壁は、このフランジ切り欠き溝２３に排水孔５周縁部の軒樋４の底部４１が差し込まれ、かつ、フランジ２２と軒樋４の底部４１とが略平行とされてこれらが互いに摺動されるので、図４（ｂ）に示すように、フランジ２２の上下面に対して斜めになるように設けられると良い。斜めの角度は、フランジ２２の厚みや軒樋４の底部４１の厚みによって変化させればよく、状況に応じて直角を含め適宜適当な角度に変更して決められれば良い。   As for the side wall of the flange cutout groove 23, the bottom 41 of the eaves 4 at the periphery of the drain hole 5 is inserted into the flange cutout groove 23, and the flange 22 and the bottom 41 of the eaves 4 are substantially parallel to each other. Since these are slid with respect to each other, as shown in FIG. The oblique angle may be changed depending on the thickness of the flange 22 and the thickness of the bottom 41 of the eaves 4 and may be determined by appropriately changing to an appropriate angle including a right angle depending on the situation.

外円筒体３のフランジ３２の外径ｄ２は、図１に示すように、内円筒体２のフランジ２２の外径ｄ１よりも大きくされている。   The outer diameter d2 of the flange 32 of the outer cylindrical body 3 is larger than the outer diameter d1 of the flange 22 of the inner cylindrical body 2, as shown in FIG.

図１の自在ドレン１を軒樋の底部に取り付ける手順の一例を図５を参照して説明する。まず、図５（ａ）に示すように、軒樋４の底部４１のドレン取り付け位置に、内円筒体２の円筒２１の外径と等しいか、あるいは少し大きい内径の排水孔５を設ける。この排水孔５の内周縁の一点から、排水孔と同心で内円筒体２のフランジ２２の外径と同じ大きさの仮想円の円周上まで、軒樋側の切り欠き溝５１を設ける。この切り欠き溝５１の幅ａ２は内円筒体２のフランジ２２の厚みｔ１よりも大きくする。   An example of a procedure for attaching the free drain 1 of FIG. 1 to the bottom of the eaves will be described with reference to FIG. First, as shown in FIG. 5A, the drain hole 5 having an inner diameter that is equal to or slightly larger than the outer diameter of the cylinder 21 of the inner cylindrical body 2 is provided at the drain attachment position of the bottom 41 of the eaves rod 4. A cutout groove 51 on the eaves side is provided from one point on the inner peripheral edge of the drainage hole 5 to the circumference of a virtual circle concentric with the drainage hole and having the same size as the outer diameter of the flange 22 of the inner cylindrical body 2. The width a2 of the cutout groove 51 is made larger than the thickness t1 of the flange 22 of the inner cylindrical body 2.

その際、内円筒体２側の切り欠き溝２３、軒樋４側の切り欠き溝５１を、図４（ａ）に示すように、フランジ面あるいは軒樋の底面に対して垂直に設けるよりも、図４（ｂ）に示すように、フランジ面あるいは軒樋の底面に対して斜めに設けると、両切り欠き溝２３、５１を利用しての内円筒体２の取り付けをより簡単にできる。   At that time, the notch groove 23 on the inner cylindrical body 2 side and the notch groove 51 on the eaves ridge 4 side are provided perpendicular to the flange surface or the bottom surface of the eaves ridge, as shown in FIG. As shown in FIG. 4 (b), when it is provided obliquely with respect to the flange surface or the bottom surface of the eaves, it is possible to more easily attach the inner cylindrical body 2 using both the cutout grooves 23 and 51.

つぎに、図５（ｂ）に示すように、軒樋４の下方から、内円筒体２のフランジ２２を上側にして、フランジ２２を軒樋４の底部４１と平行にして排水孔５下面に沿わせる。軒樋側の切り欠き溝５１を捩り広げて、内円筒体２のフランジ２２を軒樋４の底部４１の軒樋側の切り欠き溝５１に差し込む。更に、フランジ２２側の切り欠き溝２３を捩り広げて、軒樋４の排水孔５１の内周面５１１に当て、軒樋４の底部４１を内円筒体２のフランジ切り欠き溝２３に差し込む。   Next, as shown in FIG. 5 (b), from the lower side of the eaves rod 4, the flange 22 of the inner cylindrical body 2 is set to the upper side, and the flange 22 is parallel to the bottom 41 of the eaves rod 4, so Keep along. The cutout groove 51 on the eaves side is twisted and expanded, and the flange 22 of the inner cylindrical body 2 is inserted into the cutout groove 51 on the eaves side of the bottom 41 of the eaves 4. Further, the notch groove 23 on the flange 22 side is twisted and expanded so as to hit the inner peripheral surface 511 of the drain hole 51 of the eaves rod 4, and the bottom 41 of the eaves rod 4 is inserted into the flange notch groove 23 of the inner cylindrical body 2.

内円筒体２のフランジ２２と軒樋４の底部４１とを、それぞれの切り欠き溝２３、５１の奥まで充分に差し込むと、内円筒体２の円筒２１が排水孔５と略同軸の位置にくる。なお、内円筒体２のフランジ２２と軒樋４の底部４１とは、それぞれ切り欠き溝５１又は切り欠き溝２３に差し込まれて捩られているが、内円筒体２のフランジ２２と軒樋２の底部４１とはいずれも強度と弾性変形に富んでいるので、捩られた変形形状は、内円筒体２の取り付け後は元の形状に戻る。   When the flange 22 of the inner cylindrical body 2 and the bottom 41 of the eaves ridge 4 are fully inserted into the notch grooves 23 and 51, the cylinder 21 of the inner cylindrical body 2 is positioned substantially coaxially with the drain hole 5. come. The flange 22 of the inner cylindrical body 2 and the bottom 41 of the eaves ridge 4 are respectively inserted into the notch groove 51 or the notch groove 23 and twisted. Since the bottom part 41 is rich in both strength and elastic deformation, the twisted deformed shape returns to the original shape after the inner cylindrical body 2 is attached.

次いで、内円筒体２のフランジ２２と軒樋２の底部４１とをそれぞれ切り欠き溝２３、５１の奥まで押し込んだ状態で、内円筒体２の円筒２１を、フランジ２２の切り欠き溝２３の軒樋４の上方に位置する側を先頭にして回す。このように内円筒体２の円筒２１を回すと、フランジ２２の切り欠き溝２３は排水孔５の周縁部の内面を摺動しながら移動し、切り欠き溝２３の後側の内円筒体２のフランジ２２が、フランジの回転に連れて軒樋４側の切り欠き溝５１を通過し、内円筒体２のフランジ２２全体が軒樋４の底部４１の上方に移動する。 Next, in a state where the flange 22 of the inner cylindrical body 2 and the bottom 41 of the eaves 2 are pushed into the notch grooves 23 and 51 respectively, the cylinder 21 of the inner cylinder 2 is inserted into the notch groove 23 of the flange 22. Turn with the side located above the eaves 4 at the top. When the cylinder 21 of the inner cylindrical body 2 is thus rotated, the cutout groove 23 of the flange 22 moves while sliding on the inner surface of the peripheral edge of the drain hole 5, and the inner cylinder 2 on the rear side of the cutout groove 23. As the flange rotates, the flange 22 passes through the notch groove 51 on the eaves rod 4 side, and the entire flange 22 of the inner cylindrical body 2 moves above the bottom 41 of the eaves rod 4.

内円筒体２のフランジ２２全体が軒樋４の底部４１内面上に移動したら、軒樋４の排水孔５から下方に突出している内円筒体２の雄ねじに外円筒体３の雌ねじをねじ込み、両円筒体のフランジ２２，３２間にて軒樋４の排水孔５の周縁部を挟持することで自在ドレンの取り付けを完了する。   When the entire flange 22 of the inner cylindrical body 2 moves on the inner surface of the bottom 41 of the eaves rod 4, the female screw of the outer cylindrical body 3 is screwed into the male screw of the inner cylindrical body 2 protruding downward from the drain hole 5 of the eaves rod 4. The attachment of the free drain is completed by sandwiching the peripheral edge of the drain hole 5 of the eaves 4 between the flanges 22 and 32 of both cylindrical bodies.

外円筒体３のフランジ３２の外径ｄ２が内円筒体２のフランジ２２の外径ｄ１よりも大きくされているので、自在ドレン１を軒樋４に取り付けた後、下から取付個所を見上げても、軒樋４側の切り欠き溝５１は見えず見栄えが良い。   Since the outer diameter d2 of the flange 32 of the outer cylindrical body 3 is made larger than the outer diameter d1 of the flange 22 of the inner cylindrical body 2, the flexible drain 1 is attached to the eaves 4 and then the mounting location is looked up from below. However, the cutout groove 51 on the eaves 4 side is not visible and looks good.

なお、軒樋の内面に、あるいは軒樋と接する内円筒体のフランジ面に、接着剤あるいはシール材を塗布して内円筒体２の取付作業を行っても良く、外円筒体を内円筒体に螺合する時に、外円筒体のフランジ面と軒樋の底部との間に接着剤、シール材或いは止水パッキン等を併用して、止水を確実にしても良い。   The inner cylinder 2 may be attached by applying an adhesive or a sealing material to the inner surface of the eaves or the flange surface of the inner cylinder that is in contact with the eaves. When screwing together, an adhesive, a sealing material, or a waterproof seal may be used in combination between the flange surface of the outer cylindrical body and the bottom of the eaves so as to ensure the waterproof.
