この発明は、壁板又は床板に埋設させる形式の埋設式ガス栓の取付構造に関する。 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a mounting structure of a buried type gas plug of the type embedded in a wall plate or floor plate.
壁裏又は床下に埋設させる埋設式ガス栓の取付構造として、実開平５−５０２６５号公報（特許文献１）に開示のものを考案した。
このものでは、図５及び図６に示すように、床板(4)に開けたガス栓取付用孔(40)から、床下に既設のガス配管(41)を室内へ引き出すと共に、これを、予めケーシング(30)内に固定させたガス栓本体(3)に接続し、その後、ガス配管(41)と共に、ガス栓本体(3)を収納させたケーシング(30)をガス栓取付用孔(40)内に落とし込んで、ガス栓取付用孔(40)の周辺の床板(4)に固定させる。
ケーシング(30)の上方開放端には、床板(4)の表面側からガス栓取付用孔(40)の周辺に係止させる鍔部(31)が張り出している。また、床面(4)の裏面側には添設板(32)が設けられている。これら鍔部(31)と添設板(32)とで床板(4)のガス栓取付用孔(40)の周辺を表裏から挟み込み、添設板(32)に螺合させた締付けネジ(36)で締付けることにより、床板(4)は、鍔部(31)と添設板(32)とによって表裏から挟圧されて、ケーシング(30)はガス栓取付用孔(40)内に取り付けられる。
As an attachment structure of the buried type gas plug buried under the wall or under the floor, the one disclosed in Japanese Utility Model Laid-Open Publication No. 5-50265 (Patent Document 1) has been devised.
In this case, as shown in FIGS. 5 and 6, the existing gas pipe (41) under the floor is drawn into the room from the gas plug mounting hole (40) opened in the floor plate (4), It is connected to the gas plug body (3) fixed in the casing (30), and then the casing (30) containing the gas plug body (3) together with the gas pipe (41) is formed into the gas plug mounting hole (40). ) And fix it on the floor plate (4) around the gas plug mounting hole (40).
At the upper open end of the casing (30), a flange portion (31) which is engaged with the periphery of the gas plug mounting hole (40) from the surface side of the floor plate (4) protrudes. Moreover, the attachment board (32) is provided in the back surface side of a floor surface (4). A clamping screw (36) is provided by sandwiching the periphery of the gas plug mounting hole (40) of the floor plate (4) from the front and back by the flange portion (31) and the attachment plate (32) and screwing the attachment plate (32). ), The floor plate (4) is pressed from the front and back by the flange portion (31) and the attachment plate (32), and the casing (30) is mounted in the gas plug mounting hole (40) .
添設板(32)付きの締付けネジ(36)は、鍔部(31)の対向する各位置にそれぞれ設けられており、ケーシング(30)をガス栓取付用孔(40)内に落とし込む際に、添設板(32)が邪魔にならないように、ケーシング(30)の周壁のうち、添設板(32)付きの締付けネジ(36)を具備させた側の両側壁に、図６に示すように、締付けネジ(36)の軸部が挿通可能な縦孔(33a)と、これに連続し且つ添設板(32)が挿通可能な横孔(33b)からなる逆Ｔ字状の逃がし孔(33)が形成されている。 The fastening screw (36) with the attachment plate (32) is provided at each position opposite to the flange (31), and when the casing (30) is dropped into the gas plug mounting hole (40) In the peripheral wall of the casing (30) shown in FIG. 6 on the side wall provided with the clamping screw (36) with the attachment plate (32) so that the attachment plate (32) does not get in the way Thus, a reverse T-shaped relief consisting of a vertical hole (33a) through which the shaft portion of the tightening screw (36) can be inserted and a horizontal hole (33b) continuous to this and through which the attachment plate (32) can be inserted Holes (33) are formed.
このように、従来の埋設式ガス栓の取付構造では、ケーシング(30)に逃がし孔(33)が貫通形成されているため、室内と壁板又は床板(4)の裏側とが逃がし孔(33)を介して連通する構造となっている。このため、ガス栓本体(3)のプラグ筒(3a)にソケット（図示せず）を接続させる際に、ガス栓取付用孔(40)を閉塞するように取付られる化粧板（図示せず）の開閉扉を開くと、壁板や床板(4)の裏側の冷気が室内に流れ込み、冬季においては室内の温度を低下させてしまうといった不都合があった。 As described above, in the conventional buried type gas plug mounting structure, the escape hole (33) is formed in the casing (30), so the escape hole (33) is formed between the room and the back side of the wall plate or floor plate (4). It has a structure which communicates via the Therefore, when connecting a socket (not shown) to the plug cylinder (3a) of the gas plug body (3), a decorative plate (not shown) attached so as to close the gas plug mounting hole (40) When the open / close door is opened, the cold air on the back side of the wall plate or floor plate (4) flows into the room, and the temperature of the room is lowered in winter.
この不都合を解消するために、この考案のものでは、図５に示すように、気密シート(S)で、ケーシング(30)の内面を覆うことで、ケーシング(31)の内外の通気を遮断し、壁板や床板(4)の裏側の冷気が逃がし孔(33)から室内へ侵入するのを防止している。 In order to solve this problem, according to the present invention, as shown in FIG. 5, by covering the inner surface of the casing (30) with an airtight sheet (S), the air flow inside and outside the casing (31) is blocked. The cold air on the back side of the wall plate or floor plate (4) is prevented from entering the room through the escape hole (33).
しかしながら、気密シート(S)を、ケーシング(30)の内面や底面又はガス栓本体(3)の基部(3b)に密着させて設置することは難しく、気密シート(S)が、前記開閉蓋の開閉動作や、プラグ筒(3a)へのソケットの脱着操作の妨げとなって円滑に作業できない不都合があったり、気密シート(S)の装着作業が面倒で手間取ったり、さらには、気密シート(S)が不用意に破れた場合、ケーシング(30)の内外の空気が連通してしまうといった不都合がある。 However, it is difficult to place the airtight sheet (S) in close contact with the inner surface or the bottom of the casing (30) or the base (3b) of the gas plug body (3), and the airtight sheet (S) There is a disadvantage that the opening and closing operation and the removal operation of the socket to the plug cylinder (3a) are obstructed so that the operation can not be performed smoothly, the installation work of the airtight sheet (S) is troublesome and takes time, and further, the airtight sheet (S) Is broken, there is a disadvantage that the air inside and outside the casing (30) will be communicated.

締付けネジが締付けられると、揺動金具は、ナット金具の移動に伴って、前記付勢手段の付勢力に抗して９０度回動し、ガイド板がケーシングの周壁に沿い且つ添設板が鍔部の裏側に略平行に位置する取付姿勢となる』ことを特徴とする。
The mounting structure of the buried type gas plug according to the present invention taken to solve the above-mentioned problems, “A guide plate is extended in a direction perpendicular to the attachment plate from one side of the attachment plate The rocking bracket of the
The screw shaft of the clamping screw is set longer than the depth of the casing,
A nut fitting that supports the rocking fitting in a retaining state and is movable to the flange side as the tightening screw is tightened is screwed onto the screw shaft.
When the nut fitting is positioned in the vicinity of the tip of the screw shaft of the tightening screw, the guide plate is positioned substantially parallel to the back surface of the bottom wall of the casing and the additional plate is outside the periphery of the bottom wall. Biasing means is provided for biasing the rocking fitting so as to be held in the insertion orientation facing
When the tightening screw is tightened, the rocking bracket rotates 90 degrees against the biasing force of the biasing means as the nut fitting moves, and the guide plate follows the peripheral wall of the casing and the additional plate The mounting posture is substantially parallel to the back side of the buttocks.
上記手段は次のように作用する。
ケーシングの底壁を貫通するようにガス栓本体を取り付けると共に、壁板又は床板に開けられたガス栓取付用孔から、その裏側に予め配設されているガス配管を室内へ引き出して前記ガス栓本体に接続させる。ケーシングの鍔部の所定位置に締付けネジを貫通させた後、そのネジ軸に断面略Ｌ字状の揺動金具を挿通させ、さらに、ナット金具を螺合させる。
ネジ軸の長さはケーシングの深さよりも長く設定されているから、ナット金具をネジ軸の先端に位置させれば、揺動金具は、ケーシングの底壁を超えた位置でナット金具により抜け止め状態に保持される。このとき、揺動金具は、ガイド板がケーシングの底壁の裏面に略平行に位置し且つ添設板がケーシングの底壁の周縁よりも外側にてネジ軸の先端側へ向く挿入姿勢に保持されるように、付勢手段によって付勢され、これに伴い、締付けネジも、ケーシングの周壁側（内側）に揺動させられた姿勢となる。
前記付勢手段の付勢力によって揺動金具を前記挿入姿勢に保持し、締付けネジをケーシングの周壁側に揺動させた状態に保持した状態で、ケーシングを、締付けネジ、揺動金具及びナット金具と共にガス栓取付用孔に挿入し、鍔部をその周辺の壁板又は床板の表面に添設させる。
The above means operate as follows.
The gas plug main body is attached so as to penetrate the bottom wall of the casing, and the gas pipe previously disposed on the back side is drawn out from the gas plug mounting hole opened in the wall plate or floor plate to the chamber Connect to the body. After a fastening screw is penetrated to a predetermined position of the flange portion of the casing, a rocking fitting having a substantially L-shaped cross section is inserted through the screw shaft, and a nut fitting is screwed.
Since the length of the screw shaft is set to be longer than the depth of the casing, if the nut fitting is positioned at the tip of the screw shaft, the rocking fitting is prevented by the nut fitting at a position beyond the bottom wall of the casing. It is held in the state. At this time, the rocking fitting is held in an insertion orientation in which the guide plate is positioned substantially parallel to the back surface of the bottom wall of the casing and the attachment plate faces the tip of the screw shaft outside the periphery of the bottom wall of the casing As described above, the clamping means is biased by the biasing means, and accordingly, the clamping screw is also pivoted to the peripheral wall side (inner side) of the casing.
The casing is held in a state in which the rocking metal fitting is held in the inserted position by the urging force of the urging means and the tightening screw is rocked to the peripheral wall side of the casing. And insert the flange into the surface of the wall plate or floor plate around it.
鍔部をガス栓取付用孔の周辺の壁板又は床板の表面に添設させた後、締付けネジを締付けると、揺動金具は、ネジ軸を鍔部側へ移動するナット金具によって押されることにより、付勢手段の付勢力に抗して９０度回動し、締付けネジを外側に揺動させてケーシングの周壁に沿わせると共に、ガイド板がケーシングの周壁に沿い且つ添設板が鍔部に略平行な取付姿勢となる。その後、締付けネジを最終締め付け状態に達するまで締付けると、添設板はガス栓取付用孔の周辺の壁板又は床板の裏面に当接し、添設板と鍔部とで前記壁板又は床板を表裏から挟圧する態様で、ケーシングはガス栓取付用孔内に固定される。 After the flange is attached to the surface of the wall plate or floor plate around the gas plug mounting hole, tightening the tightening screw will cause the rocking metal fitting to be pushed by the nut fitting that moves the screw shaft to the flange side. Urges the clamping screw outward along the peripheral wall of the casing, while the guide plate is along the peripheral wall of the casing and the attachment plate is flanged The mounting posture is approximately parallel to the After that, when the tightening screw is tightened to the final tightening state, the attachment plate abuts against the back of the wall plate or floor plate around the gas plug mounting hole, and the wall plate or floor plate The casing is fixed in the gas plug mounting hole in such a manner as to press from the front and back.
上記埋設式ガス栓の取付構造において、『前記ガイド板の両側辺からガイド板に対して直角に且つ前記添設板と同じ方向に突出する一対の耳部が設けられ、
各耳部の先端近傍に係止孔が貫通し、
前記付勢手段は、前記ガス栓本体のうちケーシングの底壁から外方に突出している部分に一回以上巻回させてなるコイル部と、前記コイル部の両端に延長し且つ前記ガス栓から離反する方向に引っ張られることにより前記コイル部を弾性的に縮径させる一対の腕部とからなる金属線バネとし、
前記腕部の先端は前記耳部の係止孔にそれぞれ係止されている』ことが望ましい。
このものでは、揺動金具が前記挿入姿勢のとき、コイル部はガス栓本体より大径に巻回されており、揺動金具が挿通姿勢から取付姿勢へ９０度回動するとき、耳部に係止させた腕部の先端が回動方向に引っ張られることにより、コイル部が縮径方向に弾性変形するように設定されている。すなわち、揺動金具は、金属線バネの弾性復帰力によって、挿入姿勢に保持されることとなる。
In the above-mentioned mounting structure of the buried type gas plug, “a pair of lugs are provided which project from both sides of the guide plate at a right angle to the guide plate and in the same direction as the attachment plate;
A locking hole penetrates near the tip of each ear,
The biasing means includes a coil portion wound one or more times around a portion of the gas plug body projecting outward from the bottom wall of the casing, and extends to both ends of the coil portion and from the gas plug A metal wire spring comprising a pair of arm portions that elastically reduce the diameter of the coil portion by being pulled in a separating direction;
It is preferable that the tip end of the arm portion be locked in the locking hole of the ear portion.
In this case, the coil portion is wound larger in diameter than the gas plug body when the rocking metal fitting is in the insertion posture, and when the rocking metal fitting rotates from the insertion posture to the mounting posture by 90 degrees, The coil portion is set to be elastically deformed in the diameter reducing direction by pulling the tip end of the locked arm portion in the rotation direction. That is, the rocking metal fitting is held in the insertion posture by the elastic return force of the metal wire spring.
上記埋設式ガス栓の取付構造において、『前記ケーシングは略円筒状に形成されると共に、その周壁のうち、対向する両側壁に、相互に平行に位置する平面部が形成され、この平面部側に位置する前記鍔部の各位置に前記締付けネジを挿通させるネジ挿通孔がそれぞれ形成され、
一対の締付けネジの各々に前記揺動金具と前記付勢手段を具備させている』ものが望ましい。
ケーシングを略円筒状とすることで、壁板や床板に形成するガス栓取付用孔を、ホールソーを使って円形に形成することができるから、施工の作業性が良い。この円形のガス栓取付用孔にケーシングを挿入すると、ケーシングの対向する両側壁を構成する平面部と円形のガス栓取付用孔の周縁との間に、比較的広い隙間が生じる。この隙間に対応する鍔部にネジ挿通孔が形成され、これに、揺動金具やナット金具を具備させた締付けネジが挿通されると共に、揺動金具は、付勢手段によって、挿入姿勢に保持された状態に付勢される態様となるため、ケーシングをガス栓取付用孔に挿入するとき、揺動金具やナット金具がガス栓取付用孔に引っ掛かることがなく、ケーシングのガス栓取付用孔への挿入が容易となる。
また、締付けネジを締付けて揺動金具を移動させる際に、ガイド板を平面部に沿わせることができるから、揺動金具をスムーズに且つ真っ直ぐに移動させることができると共に、ケーシングは、鍔部のうち、対向する２か所で挟圧されることとなるから、ケーシングを安定した状態でガス栓取付用孔内に固定させることができる。
In the mounting structure of the buried type gas plug, “the casing is formed in a substantially cylindrical shape, and flat portions positioned in parallel with each other are formed on opposite side walls of the peripheral wall, and the flat portion side Screw insertion holes through which the tightening screws are inserted are respectively formed at respective positions of the flanges located in
Preferably, the rocking fitting and the biasing means are provided on each of a pair of tightening screws.
By making the casing into a substantially cylindrical shape, the gas plug mounting holes formed in the wall plate and the floor plate can be formed in a circular shape using a hole saw, so that the workability of the construction is good. When the casing is inserted into the circular gas plug mounting hole, a relatively wide gap is generated between the flat portion forming the opposite side walls of the casing and the periphery of the circular gas plug mounting hole. A screw insertion hole is formed in a flange portion corresponding to the gap, and a tightening screw provided with a rocking metal fitting or a nut metal fitting is inserted into the screw insertion hole, and the rocking metal fitting is held in the insertion posture by biasing means. Because the rocking fitting and the nut fitting are not caught in the gas plug mounting hole when the casing is inserted into the gas plug mounting hole, the gas plug mounting hole of the casing is inserted. It is easy to insert into.
In addition, when moving the rocking bracket by tightening the tightening screw, the guide plate can be made to be along the flat portion, so that the rocking metal fitting can be moved smoothly and straightly, and the casing is Among the above, since the pressure is clamped at two opposing positions, the casing can be fixed in the gas plug mounting hole in a stable state.
なお、上記埋設式ガス栓の取付構造において、『前記ケーシングの深さ方向に沿った前記平面部の中心線上に、締付けネジのネジ軸が嵌入可能な凹溝が形成されると共に、前記ガイド板の前記平面部に沿う側の面に、前記凹溝に摺動可能に嵌り込む凸条が形成されている』ものが望ましい。
このものでは、揺動金具を締付けネジの先端にナット金具と共に具備させた状態で挿入姿勢に付勢させると、ネジ軸の一部が凹溝に嵌入可能となるから、締付けネジを、凹溝の深さ分、ケーシング側へ大きく揺動させた状態に付勢させることができる。
また、締付けネジの締付けによって、ガイド板に設けた凸条をケーシングの両側壁に設けた凹溝内に嵌め込んだ状態で揺動金具を鍔部側に移動させることができるので、添設板が壁板や床板の裏面に対して歪むことなくまっすぐに取付姿勢を保持したまま引き上げることができる。
In the above-described mounting structure of the buried type gas plug, “a concave groove into which a screw shaft of a tightening screw can be inserted is formed on the center line of the flat portion along the depth direction of the casing, It is preferable that a ridge formed to be slidably fitted in the recessed groove is formed on the surface on the side along the flat portion.
In this case, a part of the screw shaft can be fitted into the concave groove when the rocking metal fitting is equipped with the nut metal fitting at the tip of the clamping screw and the part is screwed into the concave groove. It is possible to urge the casing side to a large swing to the depth of.
In addition, since the rocking metal fitting can be moved to the flange side in a state in which the protruding strips provided on the guide plate are fitted into the recessed grooves provided on the both side walls of the casing by tightening the fastening screws. But can be pulled up while holding the mounting posture straight without being distorted relative to the back of the wall board or floor board.
さらに、上記埋設式ガス栓の取付構造において、『ケーシングの底壁にガス栓本体を挿通させるためのガス栓挿通孔が形成され、前記ガス栓本体を取り付けるためのガス栓取付部は、前記ガス栓本体と前記ガス栓挿通孔との隙間を閉塞するように、前記ケーシングの底壁に設けられる』ことが望ましい。
このものでは、ケーシングの底壁に形成されるガス栓挿通孔からの通気を、ガス栓取付部によって遮断する構成としたから、ガス栓挿通孔から底壁の裏側の冷気や塵芥がケーシング内に侵入してくることはない。また、前記ガス栓本体と前記ガス栓挿通孔との隙間から小物等をケーシングの裏側へ落とす不都合もない。
Furthermore, in the mounting structure of the buried type gas plug, “a gas plug insertion hole for inserting the gas plug main body is formed in the bottom wall of the casing, and the gas plug mounting portion for mounting the gas plug main body is the gas Preferably, it is provided on the bottom wall of the casing so as to close the gap between the plug body and the gas plug insertion hole.
In this case, since air flow from the gas plug insertion hole formed in the bottom wall of the casing is blocked by the gas plug mounting portion, cold air or dust on the back side of the bottom wall from the gas plug insertion hole is contained in the casing. It does not invade. In addition, there is no inconvenience of dropping small articles and the like to the back side of the casing from the gap between the gas plug body and the gas plug insertion hole.
付勢手段によって、揺動金具の略全体が、ケーシングの底壁の裏側に位置させる挿入姿勢に保持された状態に付勢されると共に、締付けネジもケーシングの周壁側に揺動された状態で保持されるから、締付けネジや揺動金具やナット金具を具備させた状態のケーシングをガス栓取付用孔内に容易に落とし込んで固定することができる。よって、ケーシングの周壁に、締付けネジや添設板等を逃がすための逃がし孔を設ける必要がないから、室内と、壁板又は床板の裏面との通気が連通することなく、壁板や床板の裏側の冷気が室内に侵入する不都合を確実に防止することができる。
また、締付けネジを締付けるだけで、揺動金具を、付勢手段の付勢力に抗して９０度回動させて、ガイド板がケーシングの周壁に沿い且つ添設板が壁板や床板に平行となる取付姿勢と姿勢変更することができ、この取付姿勢のまま壁板や床板の裏面に向かって移動させて、鍔部と添設板で壁板や床板を挟圧させてケーシングを取り付けることができるので、ケーシングのガス栓取付用孔への取付作業が容易となり、施工性が向上する。
さらに、施工後の取付方向の変更やガス栓のメンテナンスにおいても、締付けネジを初期位置まで緩めるだけで揺動金具を初期位置（挿入姿勢）に復帰させることができ、ガス栓本体をガス配管と共に容易に引き出すことができるので、メンテナンス性に優れたものとなる。
The biasing means biases substantially the entire rocking fitting in the inserted position to be positioned behind the bottom wall of the casing, and the tightening screw is also rocked toward the peripheral wall of the casing. Since it is held, it is possible to easily drop and fix the casing provided with the tightening screw, the swing fitting and the nut fitting in the gas plug mounting hole. Therefore, there is no need to provide a relief hole for releasing the tightening screw, attachment plate, etc. in the peripheral wall of the casing, so that ventilation between the room and the back of the wall plate or floor plate does not communicate. It is possible to reliably prevent the inconvenience that cold air on the back side intrudes into the room.
In addition, just by tightening the tightening screw, the rocking bracket is rotated 90 degrees against the biasing force of the biasing means, and the guide plate is along the peripheral wall of the casing and the attachment plate is parallel to the wall plate or floor plate The mounting posture and posture can be changed, and the mounting posture is moved toward the back of the wall plate or floor plate as it is, and the wall plate or floor plate is pinched by the flange portion and the additional plate to attach the casing. As a result, the mounting work of the casing to the gas plug mounting hole is facilitated, and the workability is improved.
Furthermore, also in changing the installation direction after installation and maintaining the gas plug, the rocking metal fitting can be returned to the initial position (insertion posture) simply by loosening the tightening screw to the initial position, and the gas plug body together with the gas pipe Since it can be easily pulled out, it becomes excellent in maintainability.
また、付勢手段として金属線バネを採用したものでは、金属線バネの一端を揺動金具に設けた耳部の一方に係止孔に係止し、ガス栓本体に１回以上巻回させた後に、他端を耳部の他方の係止孔に係止させるだけで取付けられるから、付勢手段の構造及び取付けが簡単であり、揺動金具を、金属線バネの両腕部の先端が係止可能な構成とすれば、施工後長期間経過しても金属線バネは劣化や破損することがないので、ガス栓の交換やメンテナンス等を行う際にも締付けネジを初期位置まで緩めさえすれば揺動金具が初期位置（挿入姿勢）に復帰させることができ、ガス栓をガス配管とともに引き出すことができる。 Also, in the case of adopting a metal wire spring as the biasing means, one end of the metal wire spring is locked in one of the hooks provided on the swing metal fitting, and wound around the gas plug body once or more. After that, it is attached only by locking the other end to the other locking hole of the ear, so that the structure and mounting of the biasing means is simple, and the rocking metal fitting is the tip of both arms of the metal wire spring. If the lockable structure is used, the metal wire spring will not deteriorate or break even after a long period of construction, so loosen the tightening screw to the initial position even when replacing the gas plug or performing maintenance, etc. The rocking metal fitting can be returned to the initial position (insertion posture) by pulling the gas plug together with the gas pipe.
以下、本願発明の実施の形態を、図面に基づいて説明する。
この実施の形態に採用するガス栓は、図１に示すように、下流端にソケット接続用のプラグ部(2a)が接続されていると共に、上流端にガス配管(41)が接続される配管接続筒部(2b)が形成されている略Ｌ字状のガス栓本体(2)からなり、ケーシング(20)の底壁(20a)には、ガス栓本体(2)の前記下流端側がちょうど挿通可能な大きさのガス栓挿通孔(22)が形成されている。

Hereinafter, embodiments of the present invention will be described based on the drawings.
The gas plug employed in this embodiment is, as shown in FIG. 1, a pipe in which a plug portion (2a) for socket connection is connected to the downstream end and a gas pipe (41) is connected to the upstream end. It consists of a substantially L-shaped gas plug main body (2) in which a connection tube portion (2b) is formed, and the downstream end side of the gas plug main body (2) is just on the bottom wall (20a) of the casing (20).
