Description
本発明は、壁面に固定されたガス栓に被覆させて保護するガス栓用保護ケースに関する。 The present invention relates to a protective case for a gas valve that covers and protects a gas valve fixed to a wall surface.
上流側の配管接続部が壁板を水平に貫通し且つ下流側のソケット接続用のプラグ部が下方に向く姿勢で壁面に固定されるガス栓に、保護ケースを装着させたものとして、実開平３－８０１７９号に開示のものがある。
このものでは、壁面に固定されたガス栓の正面、両側面及び上面を覆うように保護ケースを壁面に取り付けることによって、ガス栓を直射日光や風雨又は塵芥や外的衝撃等から保護することができ、ガス栓を使用する際には、保護ケースの下方開放部からソケットを挿入させてプラグ部に接続させることができる。
Japanese Utility Model Application Publication No. 3-80179 discloses a gas valve fitted with a protective case, in which the upstream pipe connection portion penetrates horizontally through the wall panel and the downstream socket connection plug portion is fixed to the wall surface facing downward.
In this device, by attaching a protective case to the wall so as to cover the front, both sides and top of the gas valve fixed to the wall, the gas valve can be protected from direct sunlight, wind, rain, dust, external impacts, etc., and when using the gas valve, the socket can be inserted through the lower opening of the protective case and connected to the plug part.
しかしながら、上記した従来の保護ケースでは、前記下方開放部から保護ケース内に、塵や土埃、雨水の跳ね返りや虫等の異物が侵入するおそれがある。特に、ガス栓の不使用時に、これら異物が侵入し、プラグ部の先端に付着することで汚損されたり、又は、故意にいたずらされたりした場合には、ソケットを接続したときに不具合を生じさせる問題がある。よって、上記した従来の保護ケースでは、ソケットを接続させないガス栓の不使用状態においては、プラグ部の保護が不十分であった。 However, with the conventional protective cases described above, there is a risk that foreign objects such as dust, dirt, splashed rainwater, and insects may enter the protective case through the lower opening. In particular, when the gas valve is not in use, these foreign objects may enter and adhere to the tip of the plug, causing soiling, or if intentional tampering occurs, this can cause problems when the socket is connected. Therefore, with the conventional protective cases described above, protection of the plug is insufficient when the gas valve is not in use and the socket is not connected.
本発明は、上記問題点に鑑みてなされたものであり、壁面に固定されるガス栓に装着させてガス栓を保護する保護ケースであって、ガス栓の不使用時には、プラグ部を含むガス栓全体を確実に覆った状態に保持でき、ガス栓の使用時には、プラグ部側を容易に開放させて前記プラグ部へのソケットの接続を可能にするガス栓用保護ケースを提供することを課題とする。 The present invention was made in consideration of the above-mentioned problems, and aims to provide a protective case for a gas valve that is attached to a gas valve fixed to a wall surface to protect the gas valve. When the gas valve is not in use, the entire gas valve, including the plug portion, is kept securely covered, and when the gas valve is in use, the plug portion side can be easily opened to allow a socket to be connected to the plug portion.
上記課題を解決するために講じた本発明の解決手段は、
上流側の配管接続用の配管接続部が壁板を水平に貫通し且つ、下流側のソケット接続用のプラグ部が下を向く姿勢にて、前記配管接続部の基端部近傍に張り出させた鍔部で壁面に固定されるガス栓を被覆して保護する保護ケースであって、
前記鍔部の周囲を囲むように前記壁面に添設固定される壁面取付枠と、前記プラグ部の左右側方を覆う左右板と、前記プラグ部の上方を覆う上板とからなり、正面側及び下方に開放する基体ケースと、
前記基体ケースの上端近傍に揺動自在に軸支され、前記基体ケース側へ揺動させた閉塞姿勢にて、前記左右板をそれぞれ外側から被覆する左右被覆壁と、前記左右被覆壁に連続し且つ前記プラグ部の正面側を覆う正面壁と、前記左右被覆壁と前記正面壁に連続し且つ前記プラグ部の下方を覆う下被覆壁とを有する可動ケースとからなり、
前記基体ケースの前記上端近傍の両外側面又は前記可動ケースの左右被覆壁の内面上端近傍のどちらか一方に突設された軸部と、どちらか他方に設けられ且つ前記軸部が嵌まり込んで上下方向に移動可能な軸受溝とから軸支部が構成され、
前記軸部を前記軸受溝に沿って下方へ移動させたとき、前記可動ケースが前記閉塞姿勢にロックされるロック機構が設けられ、前記ロック機構によるロック状態は、前記軸部を前記軸受溝に沿って上方へ移動させると解除可能に設定されていることである。
The solution of the present invention taken to solve the above problems is:
A protective case for covering and protecting a gas cock that is fixed to a wall surface by a flange that protrudes near the base end of a pipe connection part for connecting an upstream pipe, the flange having a position where the pipe connection part for connecting a downstream socket faces downward,
a base case that is open to the front and downward and that includes a wall mounting frame that is attached and fixed to the wall so as to surround the periphery of the flange, left and right plates that cover the left and right sides of the plug section, and an upper plate that covers the top of the plug section;
a movable case that is pivotally supported near the upper end of the base case so as to be swingable, and that has left and right covering walls that cover the left and right plates from the outside, respectively, when in a closed position swung toward the base case, a front wall that is continuous with the left and right covering walls and covers the front side of the plug portion, and a lower covering wall that is continuous with the left and right covering walls and the front wall and covers a lower part of the plug portion,
a shaft portion protruding from either one of both outer surfaces near the upper end of the base case or the inner surfaces near the upper ends of the left and right covering walls of the movable case, and a bearing groove provided on the other of the two, into which the shaft portion fits and which is movable in the up and down direction;
A locking mechanism is provided that locks the movable case in the closed position when the shaft portion is moved downward along the bearing groove, and the locked state of the locking mechanism is set to be releasable when the shaft portion is moved upward along the bearing groove.
上記手段は次のように作用する。
ガス栓は、配管接続部が壁板を水平に貫通し且つプラグ部が下方に向く姿勢となるように鍔部で壁面に固定され、この鍔部を囲むように、基体ケースの壁面取付枠が壁面に取り付けられる。
基体ケースと可動ケースとは、基体ケースの上端近傍の両外側面又は前記両外側面を覆う可動ケースの左右被覆壁の内面上端近傍のどちらか一方に設けた軸部が、どちらか他方に設けた軸受溝に嵌め込まれて揺動自在に軸支される態様で一体となる。プラグ部にソケットを接続させないガス栓の不使用時には、可動ケースを基体ケース側へ揺動させて閉塞姿勢とする。この閉塞姿勢にある可動ケースが自重により又は手動による下方への移動に伴って、軸部が軸受溝に沿って下方へ移動すると、ロック機構がロック状態となって可動ケースは閉塞姿勢に保持される。
前記閉塞姿勢にて、前記プラグ部の上方は基体ケースの上板で、正面側と下方は可動ケースの正面壁と下被覆壁で、プラグ部の左右両側方は、基体ケースの左右板と可動ケースの左右被覆壁で二重に覆われた被覆状態となる。
The above means operates as follows.
The gas valve is fixed to the wall surface by the flange so that the pipe connection portion passes horizontally through the wall panel and the plug portion faces downward, and the wall mounting frame of the base case is attached to the wall surface so as to surround this flange.
The base case and the movable case are integrated in such a manner that a shaft provided on either one of both outer surfaces near the upper end of the base case or near the upper ends of the inner surfaces of the left and right covering walls of the movable case that cover both outer surfaces is fitted into a bearing groove provided on the other side and pivotally supported so as to be able to swing freely. When the gas valve is not in use and the socket is not connected to the plug part, the movable case is swung toward the base case to assume the closed position. When the shaft moves downward along the bearing groove due to the movable case's own weight or manual downward movement in this closed position, the locking mechanism enters a locked state and the movable case is maintained in the closed position.
In the closed position, the plug portion is doubly covered by the upper plate of the base case above, the front and lower sides by the front wall and lower covering wall of the movable case, and the left and right sides of the plug portion by the left and right plates of the base case and the left and right covering walls of the movable case.
閉塞姿勢にある可動ケースを上方へ移動させると、軸部が軸受溝に沿って上方へ移動すると共に前記ロック状態は解除される。ロック解除後に可動ケースを正面側へ揺動させて、プラグ部の下方が開放する開放姿勢とすれば、プラグ部にソケットを接続してガス栓を使用することができる。
また、ソケットを取り外すときは、可動ケースをソケット全体が露出するまで正面側へ大きく揺動させればソケットをプラグ部から容易に取り外すことができる。ソケットを取り外した後は、可動ケースから手を離すと、可動ケースは自重により閉塞方向に揺動した後、下方へ落下し、自動的にロックがかかる。なお、この作業は手動で行っても良い。
When the movable case is moved upward from the closed position, the shaft moves upward along the bearing groove, and the locked state is released. After the lock is released, the movable case is swung forward to the open position, where the bottom of the plug is open, and the socket can be connected to the plug and the gas valve can be used.
To remove the socket, simply swing the movable case forward until the entire socket is exposed, and the socket can be easily removed from the plug. After removing the socket, release the movable case, and it will swing in the closing direction under its own weight, then fall downward and automatically lock. This operation can also be done manually.
上記ガス栓用保護ケースにおいて、好ましくは、『前記ロック機構は、前記基体ケースの左右板の外面と、前記可動ケースの左右被覆壁の内面のどちらか一方に設けられた係合部と、どちらか他方に設けられる被係合部とからなり、
前記閉塞姿勢にある可動ケースを下方へ移動させると、前記係合部と被係合部とが係合し、前記閉塞姿勢にある可動ケースを上方へ移動させると、前記係合部と被係合部との係合が解除されるように設定されている』ことである。
ロック機構を構成する係合部と被係合部を、基体ケースの左右板の外面と可動ケースの左右被覆壁の内面とにそれぞれ設ける構成としたから、ロック機構のための部材や装置を別途設ける必用がなく、容易に且つ安価にロック機構を構成することができる。
In the above-mentioned gas cock protective case, preferably, the locking mechanism comprises an engaging portion provided on either the outer surface of the left or right plate of the base case or the inner surface of the left or right covering wall of the movable case, and an engaged portion provided on the other of the outer surface of the left or right covering wall of the movable case,
When the movable case in the closed position is moved downward, the engaging portion and the engaged portion engage with each other, and when the movable case in the closed position is moved upward, the engagement between the engaging portion and the engaged portion is released.
The engaging and engaged parts that make up the locking mechanism are provided on the outer surfaces of the left and right plates of the base case and on the inner surfaces of the left and right covering walls of the movable case, respectively, so there is no need to provide separate members or devices for the locking mechanism, and the locking mechanism can be constructed easily and inexpensively.
上記ガス栓用保護ケースにおいて、好ましくは、『前記係合部は、前記可動ケースの左右被覆壁の開放端縁から内方へ突設させた凸部とし、
前記被係合部は、前記基体ケースの左右板の外面に形成される凹溝とし、
前記凹溝は、前記左右板の正面側端縁から前記壁面取付枠に至る横溝と、前記横溝の前記壁面取付枠側の端部から下方へ連続する縦溝とから略Ｌ字状に形成されている』ことである。
前記可動ケースを閉塞方向へ揺動させると、可動ケースの左右被覆壁の開放端縁に設けた凸部が、基体ケースの左右板の外面に設けた略Ｌ字状の凹溝のうち、横溝内を横方向に移動することにより、可動ケースを基体ケース側へスムーズに揺動させて閉塞姿勢とすることができる。可動ケースが閉塞姿勢となった時点で、凸部を横溝の前記壁面取付枠側の端部から下方へ連続させた縦溝内へ移動させると、凸部の横方向への移動が阻止される。これにより、可動ケースの開放方向への揺動が阻止され、閉塞姿勢にてロックされた状態となる。
このように、ロック機構を凸部と凹溝とで構成することにより、より一層容易に且つ安価にロック機構を設けることができる。
In the gas cock protective case, preferably, the engaging portions are convex portions protruding inward from the open end edges of the left and right covering walls of the movable case,
the engaged portions are recessed grooves formed on the outer surfaces of the left and right plates of the base case,
The groove is formed in an approximately L-shape from a horizontal groove extending from the front edge of the left and right plates to the wall mounting frame, and a vertical groove continuing downward from the end of the horizontal groove on the wall mounting frame side.
When the movable case is swung in the closing direction, convex portions provided on the open edges of the left and right covering walls of the movable case move laterally within horizontal grooves of approximately L-shaped recessed grooves provided on the outer surfaces of the left and right plates of the base case, allowing the movable case to smoothly swing toward the base case and assume the closed position. Once the movable case is in the closed position, the convex portions are moved downward from the end of the horizontal groove on the wall mounting frame side into the vertical groove, preventing the convex portions from moving laterally. This prevents the movable case from swinging in the opening direction and locks it in the closed position.
In this way, by configuring the locking mechanism with a convex portion and a concave groove, the locking mechanism can be provided more easily and inexpensively.
上記ガス栓用保護ケースにおいて、好ましくは、『前記ロック機構は、前記基体ケースの壁面取付枠の下端部と、前記可動ケースの前記下被覆壁の開放端縁のどちらか一方に設けられた係合部と、どちらか他方に設けられる被係合部とからなり、
前記閉塞姿勢にある可動ケースを下方へ移動させると、前記係合部と被係合部とが係合し、前記閉塞姿勢にある可動ケースを上方へ移動させると、前記係合部と被係合部との係合が解除されるように設定されている』ことである。
このものも、ロック機構のための部材や装置を別途設ける必用がなく、容易に且つ安価にロック機構を構成することができる。
In the above-mentioned gas cock protective case, preferably, the locking mechanism comprises an engaging portion provided on either the lower end of the wall mounting frame of the base case or the open end edge of the lower covering wall of the movable case, and an engaged portion provided on the other of the engaging portion,
When the movable case in the closed position is moved downward, the engaging portion and the engaged portion engage with each other, and when the movable case in the closed position is moved upward, the engagement between the engaging portion and the engaged portion is released.
This also eliminates the need to provide separate members or devices for the locking mechanism, and the locking mechanism can be constructed easily and inexpensively.
以上のように、基体ケースに対して可動ケースを閉塞姿勢とすることで、壁面に固定されたガス栓のプラグ部の先端を含む全体を完全に覆うことができ、また、ロック機構により前記閉塞姿勢を維持することができるようにしたから、閉塞姿勢にある可動ケースが、風や悪戯等によって不用意に揺動して開放する不都合がなく、特に屋外壁面にガス栓を設置するような場合には、ガス栓を直射日光や風雨から確実に保護することができると共に、土埃や塵芥、又は、虫等がプラグ部に付着する不都合を防止することができる。これにより、ガス栓を、長期に渡って、操作性が損なわれることなく、常に安定した状態で保護することができる。 As described above, by placing the movable case in a closed position relative to the base case, it is possible to completely cover the entire gas valve, including the tip of the plug portion, which is fixed to the wall surface. Furthermore, the locking mechanism allows this closed position to be maintained, so the movable case in the closed position will not accidentally swing open due to wind or vandalism. This ensures that the gas valve is protected from direct sunlight and wind and rain, particularly when the gas valve is installed on an outdoor wall, and also prevents dirt, dust, or insects from adhering to the plug portion. This allows the gas valve to be protected in a stable state over the long term without compromising operability.
また、ガス栓を壁面に固定させている鍔部の周囲を囲むように、基体ケースの壁面取付枠を壁面に取り付け可能とすることで、既設のガス栓に保護ケースを容易に施工することができ、保護ケースが汚れたり、疵が付いたりした場合には、ガス栓を壁面に設置させた状態のまま基体ケースや可動ケースの取り換えや修理が可能であるから、メンテナンスも容易となる。 In addition, by making it possible to attach the wall mounting frame of the base case to the wall so that it surrounds the flange that secures the gas valve to the wall, the protective case can be easily installed on an existing gas valve. If the protective case becomes dirty or damaged, the base case or movable case can be replaced or repaired while the gas valve is still installed on the wall, making maintenance easy.
以下に、本発明を実施するための最良の形態について添付図面を参照しながら説明する。
本発明の実施の形態にて採用したガス栓は、図１及び図２に示すように、上流側の配管接続用の配管接続部(41)から下流側のソケット接続用のプラグ部(4)に至るガス流路が略Ｌ字状に形成されたガス栓であり、壁板(5)に設けられた開口(50)に配管接続部(41)が水平に挿通し且つプラグ部(4)の先端が下に向く姿勢で、配管接続部(41)の基端部近傍から張り出させた鍔部(42)を壁面(51)の開口(50)の周辺に添設させる。鍔部(42)は、図３に示すように、略矩形状板であり、３か所のコーナ部に設けられたネジ挿通孔(40)に挿通させる固定ネジ（図示せず）によって、開口(50)の周辺にネジ止めされて固定される。
Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.
The gas valve employed in this embodiment of the present invention is a gas valve having a generally L-shaped gas flow path from a pipe connection portion 41 for connecting an upstream pipe to a plug portion 4 for connecting a downstream socket, as shown in Figures 1 and 2. The pipe connection portion 41 is inserted horizontally into an opening 50 provided in a wall panel 5, with the tip of the plug portion 4 facing downward, and a flange portion 42 extending from the vicinity of the base end of the pipe connection portion 41 is attached to the periphery of the opening 50 in the wall panel 51. As shown in Figure 3, the flange portion 42 is a generally rectangular plate, and is fixed to the periphery of the opening 50 by fixing screws (not shown) inserted through screw insertion holes 40 provided in three corners.
壁面(51)に添設固定させた鍔部(42)と鍔部(42)から正面側に突設させたプラグ部(4)を全体的に覆うように、保護ケース(100)を装着させる。保護ケース(100)は、鍔部(42)を嵌め込み可能な大きさ形状の開口部(10)が形成された壁面取付枠(12)によって壁面(51)に固定される基体ケース(1)と、基体ケース(1)に揺動自在に軸支される可動ケース(2)とから構成されている。 The protective case (100) is attached to the wall surface (51) so as to completely cover the flange (42) attached to the wall surface (51) and the plug (4) protruding from the flange (42) toward the front. The protective case (100) is composed of a base case (1) fixed to the wall surface (51) by a wall mounting frame (12) having an opening (10) sized and shaped to fit the flange (42), and a movable case (2) pivotally supported on the base case (1) so as to be able to swing freely.
基体ケース(1)は、図１～図３の各図に示すように、壁面取付枠(12)と、壁面取付枠(12)の左右辺から正面側へ突設されてプラグ部(4)の左右両側方を覆う左右板(11a)(11b)と、左右板(11a)(11b)の上端辺に連続し且つプラグ部(4)の上方を覆う上板(13)とからなる、正面側及び下方に開放する略矩形の箱体であって、その上方には上方延設部(14)が連設されている。また、壁面取付枠(12)の壁側の端縁からは、薄肉のフランジ片(15)が左右方向及び下方へ壁面(51)に沿うように張り出している。
なお、壁面取付枠(12)の正面の対角線上には、図３に示すように、取付け用ネジ（図示せず）を挿通させるネジ挿通孔(12a)(12b)が形成されている。
1 to 3, the base case 1 is a generally rectangular box-shaped body that is open to the front and downward and that is made up of a wall-mounting frame 12, left and right plates 11a and 11b that protrude from the left and right sides of the wall-mounting frame 12 toward the front and cover both the left and right sides of the plug portion 4, and a top plate 13 that is continuous with the upper edges of the left and right plates 11a and 11b and covers the upper part of the plug portion 4. An upward extension portion 14 is connected to the top of the top plate 13. In addition, thin flange pieces 15 protrude left and right and downward from the wall-side edge of the wall-mounting frame 12 so as to follow the wall surface 51.
As shown in FIG. 3, screw insertion holes 12a and 12b for inserting mounting screws (not shown) are formed on the diagonal line on the front surface of the wall mounting frame 12.
可動ケース(2)は、基体ケース(1)の正面側及び下方開放部を開閉自在に揺動するように、上方延設部(14)の左右両面部に軸支されており、基体ケース(1)の正面側及び下方開放部を閉塞した閉塞姿勢にて、左右板(11a)(11b)の外側をそれぞれ被覆する左右被覆壁(21a)(21b)と、左右被覆壁(21a)(21b)の正面側端縁に連続し且つプラグ部(4)の正面側を覆う正面壁(22)と、正面壁(22)の下端と左右被覆壁(21a)(21b)の下端に連続し且つプラグ部(4)の下方を覆う下被覆壁(23)とから構成されている。 The movable case (2) is pivotally supported on both the left and right sides of the upper extension (14) so as to swing open and close the front and lower openings of the base case (1). When in the closed position, which closes the front and lower openings of the base case (1), the movable case (2) is composed of left and right covering walls (21a) and (21b) that cover the outside of the left and right plates (11a) and (11b), respectively; a front wall (22) that is continuous with the front edges of the left and right covering walls (21a) and (21b) and covers the front side of the plug section (4); and a lower covering wall (23) that is continuous with the lower ends of the front wall (22) and the left and right covering walls (21a) and (21b) and covers the lower part of the plug section (4).
左右被覆壁(21a)(21b)の上端近傍内面には、図２の点線で示すように、軸部(3a)(3b)がそれぞれ内方へ突設されており、軸部(3a)(3b)が対向する上方延設部(14)の左右両側部には、図４、図５に示すように、軸部(3a)(3b)が各々嵌まり込み可能な縦長の軸受溝(30)が形成されている。左右の軸部(3a)(3b)を上方延設部(14)の左右両側部の軸受溝(30)に各々嵌め込むことにより、基体ケース(1)と可動ケース(2)は一体となり、可動ケース(2)は基体ケース(1)に対して開閉方向に揺動可能で且つ上下方向へスライド可能に組み付けられる態様となる。 As shown by the dotted lines in Figure 2, shafts 3a and 3b protrude inward from the inner surfaces of the left and right covering walls 21a and 21b near their upper ends. On the left and right sides of the upward extension 14 where shafts 3a and 3b face, vertically elongated bearing grooves 30 are formed, into which shafts 3a and 3b can fit, as shown in Figures 4 and 5. By fitting the left and right shafts 3a and 3b into the bearing grooves 30 on the left and right sides of the upward extension 14, base case 1 and movable case 2 are integrated, and movable case 2 is assembled to base case 1 so that it can swing open and close and slide up and down.
基体ケース(1)と可動ケース(2)からなる保護ケース(100)を、壁面(51)に添設固定されているガス栓に装着させるには、図２～図４に示すように、可動ケース(2)を正面側に大きく揺動させて基体ケース(1)の正面側及び下方を開放させた開放姿勢とし、壁面(51)に固定されたガス栓の鍔部(42)を、壁面取付枠(12)の開口部(10)内に位置させた状態にて、壁面取付枠(12)を壁面(51)に添設させ、図示しない取付け用ネジを、ネジ挿通孔(12a)(12b)を介して壁板(5)に捻じ込んで固定させる。 To attach the protective case (100), consisting of the base case (1) and the movable case (2), to a gas valve attached to a wall (51), as shown in Figures 2 to 4, swing the movable case (2) forward to open the front and bottom of the base case (1). Then, with the flange (42) of the gas valve attached to the wall (51) positioned within the opening (10) of the wall mounting frame (12), attach the wall mounting frame (12) to the wall (51). Then, install the mounting screws (not shown) by screwing them into the wall panel (5) through the screw insertion holes (12a) and (12b).
次に、可動ケース(2)を基体ケース(1)に対して閉塞姿勢に維持するロック機構について説明する。 Next, we will explain the locking mechanism that maintains the movable case (2) in a closed position relative to the base case (1).
この実施の形態では、ロック機構を構成する係合部としての凸部(31)は、図２の点線で示すように、可動ケース(2)の左右被覆壁(21a)(21b)における下被覆壁(23)寄りの内面の開放端縁に沿った所定位置から内方へ突設させており、凸部(31)が係合する被係合部としての凹溝(32)は、可動ケース(2)を閉塞方向に揺動させる際に、凸部(31)が対向する基体ケース(1)の左右板(11a)(11b)の外面の所定位置に形成されている。 In this embodiment, the convex portions (31) serving as engaging portions that constitute the locking mechanism protrude inward from predetermined positions along the open edges of the inner surfaces of the left and right covering walls (21a) and (21b) of the movable case (2) near the lower covering wall (23), as shown by the dotted lines in Figure 2. The concave grooves (32) serving as engaging portions with which the convex portions (31) engage are formed at predetermined positions on the outer surfaces of the left and right plates (11a) and (11b) of the base case (1) that the convex portions (31) face when the movable case (2) is swung in the closing direction.
凹溝(32)は、図２及び図４に示すように、左右板(11a)(11b)の正面側端縁に開放し且つフランジ片(15)に至る横溝(33)と、横溝(33)におけるフランジ片(15)側の端部から下方へ連続する縦溝(34)とから略Ｌ字状に形成されている。 As shown in Figures 2 and 4, the recessed groove (32) is formed in a roughly L-shape by a horizontal groove (33) that opens to the front edge of the left and right plates (11a) and (11b) and reaches the flange piece (15), and a vertical groove (34) that continues downward from the end of the horizontal groove (33) on the flange piece (15) side.
図４及び図５に示すように、可動ケース(2)の左右被覆壁(21a)(21b)の所定位置から内方へ突設させた軸部(3a)(3b)を、基体ケース(1)の上方延長部(14)の左右両側部の軸受溝(30)の上端に位置させた状態にて、可動ケース(2)は揺動自在であり、図４に示すように、基体ケース(1)の正面側及び下方を開放させたり、図５に示すように、基体ケース(1)の正面側及び下方を閉塞することができる。 As shown in Figures 4 and 5, when the shafts (3a) and (3b) protruding inward from predetermined positions on the left and right covering walls (21a) and (21b) of the movable case (2) are positioned at the upper ends of the bearing grooves (30) on both the left and right sides of the upward extension (14) of the base case (1), the movable case (2) is free to swing, and the front and bottom of the base case (1) can be opened as shown in Figure 4, or closed as shown in Figure 5.
可動ケース(2)の開放姿勢にて、ガス栓のプラグ部(4)にソケット(43)を接続することができ、ソケット(43)を接続後に、可動ケース(2)から手を離すと、可動ケース(2)は自重により、閉塞方向に自動的に揺動し、図６に示すように、可動ケース(2)の下被覆壁(23)の開放端がソケット(43)に当接する使用形態となる。
ソケット(43)を取り外す際には、再度、図４に示すように、可動ケース(2)を正面側に大きく揺動させて、基体ケース(1)の正面側及び下方を開放させれば、ソケット(43)の取外し作業を容易に行うことができる。
With the movable case (2) in the open position, the socket (43) can be connected to the plug portion (4) of the gas valve. After the socket (43) is connected, when the movable case (2) is released, the movable case (2) automatically swings in the closing direction due to its own weight, and as shown in Figure 6, the open end of the lower covering wall (23) of the movable case (2) abuts against the socket (43).
When removing the socket (43), the movable case (2) is again swung largely toward the front as shown in Figure 4 to open the front side and the bottom of the base case (1), which makes it easy to remove the socket (43).
ソケット(43)を取り外した後に、可動ケース(2)から手を離せば、可動ケース(2)は自重により閉塞方向に揺動し、図５に示すように、可動ケース(2)の開放端部が、基体ケース(1)のフランジ片(15)に当接すると同時に、凸部(31)が、基体ケース(1)の左右板(11a)(11b)の外面に設けた略Ｌ字状の凹溝(32)のうち横溝(33)内を横方向に移動して、横溝(33)のフランジ片(15)側の端部に到達する。この状態では、また、ロック機構は非ロック状態である。 After removing the socket (43), if you release the movable case (2), the movable case (2) will swing in the closing direction due to its own weight. As shown in Figure 5, the open end of the movable case (2) abuts against the flange piece (15) of the base case (1). At the same time, the convex part (31) moves laterally within the horizontal groove (33) of the approximately L-shaped recessed groove (32) on the outer surfaces of the left and right plates (11a) and (11b) of the base case (1), and reaches the end of the horizontal groove (33) on the flange piece (15) side. In this state, the locking mechanism is again in the unlocked state.
その後、可動ケース(2)は自重により落下することにより、図７に示すように、軸部(3a)(3b)が軸受溝(30)の下端まで移動すると共に、凸部(31)は縦溝(34)内へ嵌まり込む。凸部(31)が縦溝(34)内に嵌まり込むと、凸部(31)の横方向への移動が阻止されるから、可動ケース(2)は、開放方向への揺動が阻止され、閉塞姿勢にてロックされた状態となる。
なお、閉塞姿勢にある可動ケース(2)を手で下方に引っ張って、前記ロック機構をロック状態としても良い。
Thereafter, movable case 2 falls due to its own weight, and as a result, shafts 3a and 3b move to the lower end of bearing groove 30, and convex portion 31 fits into vertical groove 34, as shown in Figure 7. When convex portion 31 fits into vertical groove 34, lateral movement of convex portion 31 is prevented, and therefore movable case 2 is prevented from swinging in the opening direction and is locked in the closed position.
The locking mechanism may be locked by manually pulling the movable case (2) downwards in the closed position.
可動ケース(2)が閉塞姿勢にロックされることにより、保護ケース(100)は外的衝撃やいたずら等により不用意に開放することがなく、不使用時におけるガス栓を直射日光や風雨から確実に保護することができる上に、土埃や塵芥、又は、虫等がケース体内に侵入したり、故意にいたずらされたりする不都合も防止できる。よって、壁面(51)に取り付けられるガス栓のプラグ部(3a)を含むガス栓全体を確実に長期に渡って保護することができる。 By locking the movable case (2) in the closed position, the protective case (100) cannot be accidentally opened due to external impact or tampering. This not only reliably protects the gas valve from direct sunlight and wind and rain when not in use, but also prevents dirt, dust, insects, etc. from entering the case or being intentionally tampered with. This ensures long-term protection for the entire gas valve, including the plug portion (3a) of the gas valve that is attached to the wall surface (51).
上記ロック機構は、図７の状態にあるロック状態にある可動ケース(2)を、左右被覆壁(21a)(21b)を指で挟んで上方へ引き上げれば、凸部(31)を縦溝(34)から抜き取って、凸部(31)と縦溝(34)との係合を解除でき、図５に示す非ロック状態とすることができる。このとき、可動ケース(2)の軸部(3a)(3b)は、基体ケース(1)の軸受溝(30)の上端に位置し、可動ケース(2)は開放方向へ揺動可能となる。 The locking mechanism can be configured so that when the movable case (2) is in the locked state shown in Figure 7, the left and right covering walls (21a) and (21b) are pinched between the fingers and pulled upward, the convex portion (31) is removed from the vertical groove (34), disengaging the convex portion (31) from the vertical groove (34), and the movable case (2) can be placed in the unlocked state shown in Figure 5. At this time, the shafts (3a) and (3b) of the movable case (2) are positioned at the upper ends of the bearing grooves (30) in the base case (1), and the movable case (2) can swing in the opening direction.
ロック機構としては、上記第１番目の実施の形態における凸部(31)と凹溝(32)に限定されるものではなく、例えば、図８に示すように、可動ケース(2)の下被覆壁(23)の開放端中央部から下方へ突設させた係合突片(35)と、基体ケース(1)のフランジ片(15)の下端から正面側に突設させた係合環(36)とから構成されても良い。
このものでは、図８の(A)に示す開放姿勢にある可動ケース(2)を基体ケース(1)側へ揺動させて閉塞姿勢としただけでは、係合突片(35)は、二点鎖線の矢印に示すように、係合環(36)の上方に位置する非ロック状態に設定されている。この非ロック状態から、可動ケース(2)を下方へ移動させると、同図の(B)に示すように、係合突片(35)が係合環(36)内に嵌め込まれることにより、可動ケース(2)の揺動は阻止されてロック状態となり、可動ケース(2)の閉塞姿勢が維持される。
係合突片(35)と係合環(36)との係合状態を解除させるには、可動ケース(2)を上方へ引っ張りあげて、係合突片(35)を係合環(36)から上方へ引き抜けば良い。
The locking mechanism is not limited to the convex portion (31) and the concave groove (32) in the first embodiment described above, but may be composed of, for example, an engaging projection (35) projecting downward from the center of the open end of the lower covering wall (23) of the movable case (2), and an engaging ring (36) projecting toward the front side from the lower end of the flange piece (15) of the base case (1), as shown in FIG.
In this device, simply swinging the movable case 2 from the open position shown in Figure 8(A) toward the base case 1 to the closed position places the engaging projection 35 in an unlocked position above the engaging ring 36, as indicated by the two-dot chain arrow. When the movable case 2 is moved downward from this unlocked position, the engaging projection 35 fits into the engaging ring 36, as shown in Figure 8(B), preventing the movable case 2 from swinging and placing it in a locked position, thereby maintaining the closed position of the movable case 2.
To release the engagement between the engaging projection (35) and the engaging ring (36), the movable case (2) is pulled upward and the engaging projection (35) is pulled upward from the engaging ring (36).
なお、ロック機構としては、開放姿勢又は閉塞姿勢にある可動ケース(2)が基体ケース(1)と相互に対向し合う各位置に各々設けられ且つ、解除自在に係合可能な他の係合手段であっても良い。 The locking mechanism may also be another engaging means that is provided at each position where the movable case (2) in the open or closed position faces the base case (1) and can be releasably engaged.
上記ガス栓用保護ケースは、屋外屋内のいずれの設置型のガス栓に装着させても良く、例えば、屋内の厨房の壁面に設置したものでは、保護ケース(100)によって、燃焼機器からの輻射熱や飛散する熱湯や高温の油から、ガス栓、特に、そのプラグ部を確実に保護することができる。
また、保護ケース(100)の壁面への取付手段は、ネジ止めに限定されることはなく、接着等で取り付けるようにしても良い。
The protective case for a gas valve may be attached to any installed gas valve, whether indoors or outdoors. For example, when installed on the wall of an indoor kitchen, the protective case (100) can reliably protect the gas valve, particularly its plug portion, from radiant heat from the combustion appliance and splashes of hot water or high-temperature oil.
Furthermore, the means for attaching the protective case (100) to the wall surface is not limited to screws, but may be adhesive or the like.
