Description

本発明は、ビルトインタイプのガス器具が、ガス栓を介して建屋側のガス配管に接続されているガス器具の接続部構造に関する。   The present invention relates to a connecting structure of a gas appliance in which a built-in type gas appliance is connected to a gas pipe on a building side via a gas plug.

ビルトインタイプのガス器具は、従来、ガス栓が一体的に組み込まれた専用のガスコックを介して建屋側のガス配管に接続されていた。
その専用のガスコックとしては、建屋側のガス配管であるフレキシブル管に接続される配管側接続部と、ガス器具側に接続される連結部材を有し、その連結部材がガス器具側の雄ねじ部に螺合する雌ねじ部を備え、かつ、雌ねじ部を回転操作するために、その外周にスパナなどの工具と係合可能な略六角形の工具掛け部を備えたものが知られている（例えば、特許文献１参照）。 Conventionally, the built-in type gas appliance has been connected to a gas pipe on the building side through a dedicated gas cock in which a gas stopper is integrated.
As the dedicated gas cock, it has a pipe side connection part connected to the flexible pipe which is the gas pipe on the building side, and a connecting member connected to the gas appliance side, and the connecting member is connected to the male screw part on the gas appliance side. There is known a device having a female thread portion that is screwed and a substantially hexagonal tool hook portion that can be engaged with a tool such as a spanner on the outer periphery in order to rotate the female screw portion (for example, Patent Document 1).

特許第２９０４３４２号公報Japanese Patent No. 2904342

ところが、ビルトインタイプのガス器具を建屋側のガス配管に接続する場合、まず、ビルトイン用の台所用家具を設置し、さらに、台所用家具にガス器具を組み込んだ後、そのガス器具を建屋側のガス配管に接続することになり、そのため、ガス器具とガス配管との接続は、例えば、台所用家具の内部空間など、比較的狭い空間内で行うことになる。
その場合、上記特許文献に開示のガスコックを使用すると、例えば、ガス器具側の雄ねじ部と連結部材側の雌ねじ部を螺合させる際、連結部材外周の工具掛け部にスパナなどの工具を係合して回転操作する必要があり、それを狭い空間内で行わねばならないので、接続作業が非常に困難なものとなる欠点があった。 However, when connecting a built-in type gas appliance to a gas pipe on the building side, first install the kitchen furniture for the built-in, and then install the gas appliance in the kitchen furniture, and then install the gas appliance on the building side. Therefore, the gas appliance and the gas pipe are connected in a relatively narrow space such as an internal space of kitchen furniture.
In that case, when the gas cock disclosed in the above patent document is used, for example, when the male screw part on the gas appliance side and the female screw part on the connecting member side are screwed together, a tool such as a spanner is engaged with the tool hooking part on the outer periphery of the connecting member. Therefore, since it is necessary to perform the rotation operation and it must be performed in a narrow space, there is a disadvantage that the connection work becomes very difficult.

本発明は、このような従来の欠点に着目したもので、その目的は、たとえ狭い空間内においても、ビルトインタイプのガス器具を建屋側のガス配管に容易に接続することが可能なガス器具の接続部構造を提供することである。   The present invention pays attention to such conventional drawbacks, and its purpose is to provide a gas appliance that can easily connect a built-in type gas appliance to a gas pipe on the building side even in a narrow space. It is to provide a connection structure.

本発明の第１の特徴構成は、ビルトインタイプのガス器具が、ガス栓を介して建屋側のガス配管に接続されているガス器具の接続部構造であって、前記ガス栓が、開閉用操作部とその開閉用操作部により開弁状態と閉弁状態とに切り換え可能な弁体を備え、そのガス栓とワンタッチ式カプラの一方が一体化されて前記ガス配管側に接続され、ワンタッチ式カプラの他方が前記ガス器具側に接続され、そのガス器具側に接続された器具側カプラとガス配管側に接続された建屋側カプラとが接続されて、前記ガス器具が建屋側のガス配管に接続され、前記建屋側カプラと器具側カプラとの接続が解除された際に、前記ガス配管からのガスの流出を阻止する安全弁が前記建屋側カプラに設けられ、前記建屋側カプラと器具側カプラとの接続を解除する解除操作部が、前記建屋側カプラに対してその軸心方向に沿って移動自在に設けられ、その解除操作部の前記軸心方向への移動による解除操作を規制する環状のストッパが、前記建屋側カプラに着脱自在に外嵌されているところにある。 A first characteristic configuration of the present invention is a connecting structure of a gas appliance in which a built-in type gas appliance is connected to a gas pipe on a building side through a gas plug, and the gas plug has an opening / closing operation. And a valve body that can be switched between a valve open state and a valve closed state by an opening / closing operation unit, and one of the gas plug and the one-touch coupler is integrated and connected to the gas pipe side, and the one-touch coupler Is connected to the gas appliance side, an appliance-side coupler connected to the gas appliance side and a building-side coupler connected to the gas piping side are connected, and the gas appliance is connected to the gas piping on the building side. When the connection between the building-side coupler and the appliance-side coupler is released, a safety valve for preventing gas from flowing out from the gas pipe is provided in the building-side coupler, and the building-side coupler, the appliance-side coupler, Disconnect A release operation part is provided movably along the axial direction with respect to the building-side coupler, and an annular stopper for restricting a release operation due to movement of the release operation part in the axial direction includes the building It is in a place that is detachably fitted to the side coupler .

本発明の第１の特徴構成によれば、ガス栓とワンタッチ式カプラの一方が一体化されてガス配管側に接続され、ワンタッチ式カプラの他方がビルトインタイプのガス器具側に接続され、そのガス器具側に接続された器具側カプラとガス配管側に接続された建屋側カプラとが接続されて、ガス器具が建屋側のガス配管に接続されているので、ビルトインタイプのガス器具と建屋側のガス配管とを接続する際、ワンタッチ式カプラを接続するだけで、つまり、器具側カプラと建屋側カプラとをワンタッチ接続するだけで済む。
したがって、たとえ台所用家具の内部空間のような狭い空間内においても、建屋側のガス配管に対してビルトインタイプのガス器具を容易、確実に接続することができる。 According to the first characteristic configuration of the present invention, one of the gas stopper and the one-touch type coupler is integrated and connected to the gas piping side, and the other of the one-touch type coupler is connected to the built-in type gas appliance side. Since the appliance-side coupler connected to the appliance side and the building-side coupler connected to the gas piping side are connected, and the gas appliance is connected to the gas piping on the building side, the built-in type gas appliance and the building side coupler are connected. When connecting the gas pipe, it is only necessary to connect a one-touch type coupler, that is, only one-touch connection between the appliance side coupler and the building side coupler.
Therefore, even in a narrow space such as the interior space of kitchen furniture, the built-in type gas appliance can be easily and reliably connected to the gas piping on the building side.

そして、本発明の第１の特徴構成によれば、建屋側カプラと器具側カプラとの接続が解除された際に、ガス配管からのガスの流出を阻止する安全弁が建屋側カプラに設けられているので、例えば、何らかの理由によって、器具側カプラと建屋側カプラの接続が不測に解除されても、建屋側カプラに設けられた安全弁によりガス配管からのガスの流出は確実に阻止される。 And according to the 1st characteristic structure of this invention, when the connection of a building side coupler and an appliance side coupler is cancelled | released, the safety valve which prevents the outflow of gas from gas piping is provided in the building side coupler. Therefore, for example, even if the connection between the appliance-side coupler and the building-side coupler is unexpectedly released, the outflow of gas from the gas pipe is reliably prevented by the safety valve provided in the building-side coupler.

それに加えて、本発明の第１の特徴構成によれば、建屋側カプラと器具側カプラとの接続を解除する解除操作部が、建屋側カプラに対してその軸心方向に沿って移動自在に設けられているので、必要な場合には、解除操作部を操作して建屋側カプラと器具側カプラとの接続を解除することができる。
そして、その解除操作部の前記軸心方向への移動による解除操作を規制する環状のストッパが、建屋側カプラに外嵌されているので、必要な場合に建屋側カプラと器具側カプラとの接続を解除することができるにもかかわらず、解除操作部の解除操作を規制する環状のストッパによって、建屋側カプラと器具側カプラとの接続が誤って不測に解除されることが防止される。 In addition , according to the first characteristic configuration of the present invention, the release operation unit for releasing the connection between the building-side coupler and the appliance-side coupler is movable along the axial direction of the building-side coupler. Since it is provided, if necessary, the connection between the building-side coupler and the appliance-side coupler can be released by operating the release operation unit.
And since the annular stopper that regulates the release operation by the movement of the release operation part in the axial direction is externally fitted to the building-side coupler, the building-side coupler and the appliance-side coupler can be connected when necessary. In spite of being able to release, the annular stopper that restricts the release operation of the release operation portion prevents the connection between the building side coupler and the appliance side coupler from being accidentally released.

本発明の第２の特徴構成は、前記器具側カプラが前記ガス器具の背面に配置されているところにある。 A second characteristic configuration of the present invention is that the appliance-side coupler is disposed on the back surface of the gas appliance.

本発明の第２の特徴構成によれば、器具側カプラがガス器具の背面に配置されているので、その器具側カプラおよび器具側カプラに接続される建屋側カプラなどをガス器具の背面に配置することができ、したがって、ガス器具の下方、つまり、ガス器具がビルトインされる台所用家具などの内部空間を自由に使用することができる。
そして、器具側カプラと建屋側カプラが同じ高さレベルになるように設定されている場合には、ガス器具を建屋側に押し込むことによって、建屋側カプラと器具側カプラをワンタッチで接続することができるので、両カプラの接続作業を簡単に行うことができる。 According to the second characteristic configuration of the present invention, since the appliance-side coupler is arranged on the back surface of the gas appliance, the appliance-side coupler and the building-side coupler connected to the appliance-side coupler are arranged on the back surface of the gas appliance. Thus, the space below the gas appliance, that is, the interior space such as kitchen furniture in which the gas appliance is built, can be freely used.
If the appliance-side coupler and the building-side coupler are set to have the same height level, the building-side coupler and the appliance-side coupler can be connected with one touch by pushing the gas appliance into the building. Therefore, it is possible to easily connect both couplers.

本発明によるガス器具の接続部構造の実施の形態を図面に基づいて説明する。
本発明が対象とするガス器具は、いわゆるビルトインタイプのガス器具で、図１に示すように、システムキッチンで使用される台所用家具Ｆなどに一体的に組み込まれて使用される。図示のガス器具１はガスコンロで、そのガスコンロ１が、建屋Ｂ側に配設されたガス配管Ｐにガス栓２とワンタッチ式カプラ３を介して接続されている。
ワンタッチ式カプラ３は、図２の（ａ）、（ｂ）に詳しく示すように、建屋Ｂ側のガス配管Ｐに接続される一方のカプラ、つまり、建屋側カプラ３ａと、ガスコンロ１側に接続される他方のカプラ、つまり、器具側カプラ３ｂを備え、建屋側カプラ３ａとガス栓２が一体化された構成とされている。 An embodiment of a gas appliance connector structure according to the present invention will be described with reference to the drawings.
The gas appliance to which the present invention is directed is a so-called built-in type gas appliance, which is used by being integrated into kitchen furniture F or the like used in a system kitchen, as shown in FIG. The illustrated gas appliance 1 is a gas stove, and the gas stove 1 is connected to a gas pipe P disposed on the building B side via a gas plug 2 and a one-touch coupler 3.
As shown in detail in FIGS. 2A and 2B, the one-touch coupler 3 is connected to one coupler connected to the gas pipe P on the building B side, that is, the building-side coupler 3a and the gas stove 1 side. The other coupler, that is, the appliance side coupler 3b is provided, and the building side coupler 3a and the gas plug 2 are integrated.

ガス栓２は、開閉用操作部４とそれに連動する弁体５を備え、さらに、ガス配管Ｐが接続される入口開口６と出口通路７を備え、開閉用操作部４の回動操作に伴って弁体５が回動し、ガス配管Ｐからのガスが出口通路７へ通流する開弁状態とガスの通流を停止する閉弁状態とに切り換え可能に構成されている。
そのガス栓２と一体化された建屋側カプラ３ａは、いわゆる雌型のカプラで、器具側カプラ３ｂが挿入される接続用開口８を備え、安全弁用スプリング９によって閉弁方向に付勢された安全弁１０が内装されている。その安全弁１０の外周部には、パッキンホルダ用スプリング１１により接続用開口８側に付勢されたパッキンホルダ１２が外嵌され、さらに、その外周部には、スリーブスプリング１３により接続用開口８側に付勢された解除操作部としてのスリーブ１４が外嵌されている。 The gas stopper 2 includes an opening / closing operation unit 4 and a valve body 5 interlocked therewith, and further includes an inlet opening 6 and an outlet passage 7 to which the gas pipe P is connected. Thus, the valve body 5 rotates, and is configured to be switchable between a valve open state in which the gas from the gas pipe P flows to the outlet passage 7 and a valve closed state in which the gas flow is stopped.
The building-side coupler 3a integrated with the gas plug 2 is a so-called female-type coupler, which has a connection opening 8 into which the appliance-side coupler 3b is inserted, and is biased in the valve closing direction by a safety valve spring 9. A safety valve 10 is provided. A packing holder 12 urged to the connection opening 8 side by the packing holder spring 11 is fitted on the outer peripheral portion of the safety valve 10, and the connection opening 8 side is provided on the outer peripheral portion by the sleeve spring 13. A sleeve 14 serving as a release operation portion biased by is externally fitted.

解除操作部としてのスリーブ１４は、建屋側カプラ３ａと器具側カプラ３ｂが接続された状態において、両カプラ３ａ，３ｂの接続を解除するためのもので、建屋側カプラ３ａの軸心方向に沿って移動自在に構成され、図２の（ａ）に示すように、両カプラ３ａ，３ｂが分離された状態でボール１５に係合している。
他方、器具側カプラ３ｂは、いわゆる雄型のカプラで、ガスコンロ１に接続される出口開口１６を備え、さらに、安全弁１０に当接して安全弁１０を開弁操作する安全弁用段部１７、パッキンホルダ１２に当接してパッキンホルダ１２を押し込み操作するパッキンホルダ用段部１８、ボール１５が嵌入するボール用溝１９などを備えている。 The sleeve 14 as a release operation part is for releasing the connection between the couplers 3a and 3b in a state where the building-side coupler 3a and the appliance-side coupler 3b are connected, and extends along the axial direction of the building-side coupler 3a. As shown in FIG. 2A, both couplers 3a and 3b are engaged with the ball 15 in a separated state.
On the other hand, the appliance-side coupler 3b is a so-called male coupler and includes an outlet opening 16 connected to the gas stove 1, and further includes a safety valve step portion 17 that contacts the safety valve 10 and opens the safety valve 10, and a packing holder. 12 is provided with a packing holder step 18 for pushing the packing holder 12 in contact with it, a ball groove 19 into which the ball 15 is inserted, and the like.

建屋側カプラ３ａと器具側カプラ３ｂとの接続は、いわゆるワンタッチ式で、建屋側カプラ３ａの接続用開口８に器具側カプラ３ｂを挿入するだけで自動的に接続される。
すなわち、建屋側カプラ３ａの接続用開口８に器具側カプラ３ｂを挿入すると、図２の（ｂ）に示すように、器具側カプラ３ｂの安全弁用段部１７が、安全弁用スプリング９の付勢力に抗して安全弁１０を押し込み操作して開弁し、同時に、パッキンホルダ用段部１８が、パッキンホルダ用スプリング１１の付勢力に抗してパッキンホルダ１２を押し込み操作する。
パッキンホルダ１２の押し込みに伴って、ボール１５に対するスリーブ１４の係合が外れて、スリーブ１４がスリーブスプリング１３の付勢力によりストップリング２０に当接するとともに、ボール１５が器具側カプラ３ｂのボール用溝１９に嵌入して、両カプラ３ａ，３ｂが接続され、かつ、その接続状態が維持される。 The building-side coupler 3a and the appliance-side coupler 3b are connected by a so-called one-touch type, and are automatically connected only by inserting the appliance-side coupler 3b into the connection opening 8 of the building-side coupler 3a.
That is, when the appliance side coupler 3b is inserted into the connection opening 8 of the building side coupler 3a, the safety valve step portion 17 of the appliance side coupler 3b is urged by the safety valve spring 9 as shown in FIG. The safety valve 10 is pushed in against the opening to open, and at the same time, the packing holder step 18 pushes in the packing holder 12 against the biasing force of the packing holder spring 11.
As the packing holder 12 is pushed in, the sleeve 14 is disengaged from the ball 15, the sleeve 14 comes into contact with the stop ring 20 by the urging force of the sleeve spring 13, and the ball 15 is in the ball groove of the instrument side coupler 3 b. 19, the couplers 3a and 3b are connected, and the connected state is maintained.

つぎに、このワンタッチ式カプラ３を使用して、建屋Ｂ側に配設されたガス配管Ｐにビルトインタイプのガスコンロ１を接続する手順について説明する。ただし、以下に説明する手順は単なる一例であるため、実際の実施に際しては、手順の一部が相前後することもあり得る。
まず、ガス工事の専門家が、図３の（ａ）に示すように、建屋側カプラ３ａと一体化されたガス栓２の入口開口６に建屋Ｂの壁面や床面から延出している可撓性のガス配管Ｐを接続し、かつ、必要なガス停止処置を行ってガス工事を終了する。
その後、図３の（ｂ）に示すように、例えば、大工の専門家が台所用家具Ｆを設置し、さらに、台所用家具Ｆにガスコンロ１を組み込む。図示の例では、ガスコンロ１の下面に器具側カプラ３ｂが配置されており、この器具側カプラ３ｂは、ガスコンロ１の設置時に予め取り付けられている。 Next, a procedure for connecting the built-in type gas stove 1 to the gas pipe P disposed on the building B side using the one-touch coupler 3 will be described. However, since the procedure described below is merely an example, a part of the procedure may be mixed in actual implementation.
First, as shown in FIG. 3 (a), a gas construction expert can extend from the wall surface or floor surface of the building B to the inlet opening 6 of the gas plug 2 integrated with the building side coupler 3a. The flexible gas pipe P is connected, and necessary gas stop treatment is performed to finish the gas work.
Thereafter, as shown in FIG. 3B, for example, a carpenter expert installs the kitchen furniture F, and further incorporates the gas stove 1 into the kitchen furniture F. In the illustrated example, the appliance side coupler 3 b is disposed on the lower surface of the gas stove 1, and the appliance side coupler 3 b is attached in advance when the gas stove 1 is installed.

したがって、台所用家具Ｆにガスコンロ１を組み込んだ後においては、図３の（ｃ）に示すように、建屋側カプラ３ａと器具側カプラ３ｂを接続すればよく、必ずしもガス工事の専門家が接続作業を行う必要はない。
そして、建屋側カプラ３ａと器具側カプラ３ｂを接続した状態では、スリーブ１４をガス栓２側へ押し込み操作してボール１５に対する係合を解除しない限り、建屋側カプラ３ａと器具側カプラ３ｂの接続が解除されることはないので、両カプラ３ａ，３ｂが不測に外れる可能性は少ない。その上、図２の（ｂ）において仮想線で示すように、スリーブ１４の押し込み操作を規制する環状のストッパ２１が、建屋側カプラ３ａに外嵌されているので、両カプラ３ａ，３ｂが不測に外れる可能性は更に少なくなる。また、たとえ両カプラ３ａ，３ｂが不測に外れたとしても、安全弁用スプリング９の付勢力によって安全弁１０が自動的に閉弁され、ガス配管Ｐからのガスの流出は阻止されることになる。 Therefore, after incorporating the gas stove 1 into the kitchen furniture F, as shown in FIG. 3C, the building-side coupler 3a and the appliance-side coupler 3b may be connected, and a gas construction specialist is not necessarily connected. There is no need to do work.
When the building-side coupler 3a and the appliance-side coupler 3b are connected, the connection between the building-side coupler 3a and the appliance-side coupler 3b is performed unless the sleeve 14 is pushed into the gas plug 2 side to release the engagement with the ball 15. Is not released, it is unlikely that both couplers 3a and 3b will come off unexpectedly. In addition, as indicated by the phantom line in FIG. 2B, since the annular stopper 21 that restricts the pushing operation of the sleeve 14 is externally fitted to the building-side coupler 3a, both the couplers 3a and 3b are unexpected. The possibility of falling off is further reduced. Even if the couplers 3a and 3b are unexpectedly disconnected, the safety valve 10 is automatically closed by the urging force of the safety valve spring 9, and the outflow of gas from the gas pipe P is prevented.

〔別実施形態〕
つぎに、別の実施形態について説明するが、先の実施形態で説明した構成部品や同じ作用を有する構成部品については、重複説明を避けるため、同じ符号を付すことにより説明を省略する。 [Another embodiment]
Next, although another embodiment will be described, the same reference numerals are given to the components described in the previous embodiment and the components having the same action to avoid redundant description, and the description will be omitted.

（１）これまでの実施形態では、ガスコンロ１の下面に器具側カプラ３ｂを配置した例を示したが、図４に示すように、ガスコンロ１の背面に器具側カプラ３ｂを配置して実施することもできる。
その場合には、建屋Ｂの壁面内に配管されたガス配管Ｐにガス栓２と建屋側カプラ３ａとが一体化されたものを使用し、かつ、建屋側カプラ３ａと器具側カプラ３ｂが同じ高さレベルになるように設定することにより、図４の（ａ）に示すように、ガスコンロ１を建屋Ｂの壁面側に押し込むことによって、図４の（ｂ）に示すように、建屋側カプラ３ａと器具側カプラ３ｂをワンタッチで接続することができるので、両カプラ３ａ，３ｂの接続作業を簡単に行うことができる。
もちろん、ガスコンロ１の背面に器具側カプラ３ｂを配置した場合においても、図３を用いて説明した接続方法が適用可能であることはいうまでもない。 (1) In the previous embodiments, an example of arranging the instrument-side coupler 3b to the lower surface of the gas stove 1, as shown in FIG. 4, carried out by placing the instrument side coupler 3b to the back of the gas stove 1 You can also.
In that case, a gas pipe P piped in the wall surface of the building B is used in which the gas stopper 2 and the building side coupler 3a are integrated, and the building side coupler 3a and the appliance side coupler 3b are the same. by setting so that the height level, as shown in FIG. 4 (a), by pressing the gas stove 1 in the wall surface of the building B, as shown in FIG. 4 (b), the building-side coupler Since 3a and the appliance side coupler 3b can be connected by one touch, the connection work of both the couplers 3a and 3b can be performed easily.
Of course, it is needless to say that the connection method described with reference to FIG. 3 can be applied even when the appliance-side coupler 3b is disposed on the back surface of the gas stove 1.

（２）これまでの実施形態では、ガス器具１の一例としてガスコンロを例示して説明したが、ガス器具１としては、特にガスコンロに限るものではなく、ガスコンロ以外の各種のガス器具にも適用可能であり、さらに、都市ガス用のガス器具はもとより、プロパン用のガス器具にも適用可能である。 In the previous embodiments (2) which it has been described by way of example a gas stove as an example of the gas appliance 1, as the gas appliance 1, it is not particularly limited to the stove, to various gas appliances other than gas stove Further, it can be applied not only to gas appliances for city gas but also to gas appliances for propane.
