Description
【０００１】[0001]
この考案は、ガス器具に取付けるガスコック、更に詳しくは、閉子を全開と全 閉の中間となる弱火の位置での停止が確実に行なえるガスコックに関する。 The present invention relates to a gas cock to be attached to a gas appliance, and more particularly to a gas cock that can be reliably stopped at a low heat position which is an intermediate position between full opening and full closing.
【０００２】[0002]
ガス器具に取付けて使用される小型のガスコック（開閉栓）は、一端にガス器 具のバーナに対する接続部と他端にホース接続部を有し、ガス通路が貫通するコ ック本体のテーパ孔内に閉子を回動自在に収納し、レバーハンドルによる閉子の 回動操作によりガス通路の全開と全閉を行なうようになっている。 A small gas cock (opening / closing plug) used by attaching to a gas appliance has a connecting part for the burner of the gas tool at one end and a hose connecting part at the other end, and has a tapered hole in the cock body through which the gas passage passes. The closure is rotatably housed inside, and the gas passage is fully opened and closed by rotating the closure with a lever handle.
【０００３】 一般に、ガス通路の全開は、閉子のレバーハンドルをガス通路と平行にするこ とによって得られ、また、全閉はレバーハンドルをガス通路と直角にするように なっており、ガス通路の全開と全閉は容易に得られることになる。Generally, the full opening of the gas passage is obtained by making the lever handle of the closing member parallel to the gas passage, and the full closing is such that the lever handle is perpendicular to the gas passage. Full opening and closing of the passage will be easily obtained.
【０００４】[0004]
ところで、ガス器具においては、バーナの火力を弱火に調整したい場合があり 、このため、レバーハンドルを介して閉子を全開と全閉の中間位置に回動させな ければならないが、従来のガスコックにおいては、開閉操作時に閉子を中間位置 で位置決めする機能が全くなく、レバーハンドルを全開位置から中間位置で止め ようと回動操作したとき、どうしても回りすぎることがあり、弱火の設定がむつ かしく、バーナを消火させてしまう事態が発生するという問題がある。 By the way, in gas appliances, there are times when it is desired to adjust the heating power of the burner to low heat.Therefore, it is necessary to rotate the closure to an intermediate position between fully open and fully closed using the lever handle. There is no function to position the closure at the intermediate position during opening and closing, and when the lever handle is rotated to stop it from the fully open position at the intermediate position, it may inevitably turn too much, making it difficult to set the low heat. However, there is a problem that the burner may be extinguished.
【０００５】 そこで、この考案の課題は、閉子の中間位置での停止が正確に行なえ、弱火の 設定が容易となるガスコックを提供することにある。Therefore, an object of the present invention is to provide a gas cock that can be accurately stopped at an intermediate position of the closure and that can easily set a low heat.
【０００６】[0006]
上記のような課題を解決するため、請求項１の考案は、コック本体に設けたガ ス通路を閉子の回動操作によって開閉するようにしたガスコックにおいて、閉子 の全開と全閉の中間位置を、コック本体と閉子側にわたって設けた位置決め機構 で保持するようにした構成を採用したものである。 In order to solve the above problems, the invention of claim 1 is a gas cock in which a gas passage provided in a cock body is opened and closed by a turning operation of a closing member, and an intermediate position between full opening and closing of the closing member. It employs a structure in which the position is held by a positioning mechanism provided over the cock body and the closing side.
【０００７】 請求項２の考案は、請求項１の考案において、位置決め機構が、閉子上に連成 した円軸部の外周面に設けた凹段部と、前記円軸部の外周面と対応するようコッ ク本体で保持され、凹段部に対して係脱自在となるよう、ばねで凹段部に常時係 合する方向の移動弾性が付与された係合子とで形成されている構成を採用したも のである。According to a second aspect of the present invention, in the first aspect of the present invention, the positioning mechanism includes a concave step portion provided on an outer peripheral surface of a circular shaft portion coupled to the closure, and an outer peripheral surface of the circular shaft portion. Correspondingly, it is held by the cock body, and is formed with an engaging element that is elastically moved in a direction that always engages with the concave step so that it can be engaged with and disengaged from the concave step. Was adopted.
【０００８】 ここで、コック本体は、軸心に沿ってガス通路が貫通し、一方の端部にガス器 具バーナへの接続部と他端にホース接続部を有し、閉子はガス通路の途中に位置 するようコック本体に設けたテーパ孔内に回動自在となるよう収納され、上端に 設けたレバーハンドルで回動させることにより、ガス通路の開閉を行なうように なっている。Here, the cock body has a gas passage penetrating along the axis, has a connecting portion to the gas equipment burner at one end and a hose connecting portion at the other end, and the closure has the gas passage. It is housed rotatably in a tapered hole provided in the cock body so that it can be located midway, and the gas passage is opened and closed by rotating it with a lever handle provided at the upper end.
【０００９】[0009]
以下、この考案の実施の形態を図示例と共に説明する。 Hereinafter, embodiments of the present invention will be described with reference to the illustrated examples.
【００１０】 図示のように、コック本体１は、一方の端部にガス器具のバーナに対する接続 部２と他端側にホース接続部３を有し、軸心に沿ってガス通路４が貫通している 。As shown, the cock body 1 has a connecting portion 2 for a burner of a gas appliance and a hose connecting portion 3 at the other end at one end, and a gas passage 4 penetrates along the axis. ing .
【００１１】 上記コック本体１には、ガス通路４の途中と交差し、上面で開口するテーパ孔 ５が設けられ、このテーパ孔５内に閉子６が抜止状態で回動自在となるよう収納 され、閉子６にはガス通路４の連通と遮断を行なうための通孔７が設けられてい る。The cock body 1 is provided with a taper hole 5 that intersects with the middle of the gas passage 4 and opens at the upper surface. The taper hole 5 accommodates the closure 6 so that the closure 6 can be rotated in a detached state. The closure 6 is provided with a through hole 7 for connecting and disconnecting the gas passage 4.
【００１２】 閉子６の上部には、コック本体１の上面上に位置する円軸部８と、更にその上 部に球状頭部９とが連成され、該頭部９に閉子６を回動操作するためのレバーハ ンドル１０が通孔７の軸心と平行する配置で固定されている。A circular shaft portion 8 located on the upper surface of the cock body 1 is coupled to the upper portion of the closure 6, and a spherical head portion 9 is coupled to the upper portion of the circular shaft portion 8. The closure 6 is attached to the head portion 9. A lever handle 10 for rotating operation is fixed in an arrangement parallel to the axis of the through hole 7.
【００１３】 上記閉子６は、レバーハンドル１０を図１に実線で示す如く、ガス通路４と平 行させると、図３（Ａ）のように、通孔７は全開位置となり、また、レバーハン ドル１０を図１（Ｂ）の二点鎖線の如く、ガス通路４と直交させると、図３（Ｃ ）の如く、通孔７は全閉位置になる。When the lever handle 10 is aligned with the gas passage 4 as shown by the solid line in FIG. 1, the through hole 7 is in the fully open position as shown in FIG. When the dollar 10 is orthogonal to the gas passage 4 as shown by the chain double-dashed line in FIG. 1 (B), the through hole 7 is at the fully closed position as shown in FIG. 3 (C).
【００１４】 また、レバーハンドル１０を、図１（Ｂ）の一点鎖線の如く、全開と全閉の中 間位置にすると、図３（Ｂ）のように、ガス通路４に対する通孔７の連通量が小 さくなり、ガス流量を絞り込んで弱火の状態となる。Further, when the lever handle 10 is set to the intermediate position between the fully open position and the fully closed position as shown by the alternate long and short dash line in FIG. 1 (B), as shown in FIG. 3 (B), the through hole 7 is connected to the gas passage 4. The flow rate becomes smaller, and the gas flow rate is narrowed down, resulting in a low fire condition.
【００１５】 前記コック本体１の上面に円軸部８の外周面と対向する突部１１が設けられ、 この円軸部８と突部１１の部分に、閉子６を中間位置に保持する位置決め機構１ ２が設けられている。A protrusion 11 is provided on the upper surface of the cock body 1 so as to face the outer peripheral surface of the circular shaft portion 8. Positioning for holding the closure 6 at an intermediate position between the circular shaft portion 8 and the protrusion portion 11 is provided. Mechanism 12 is provided.
【００１６】 上記位置決め機構１２は、円軸部８の外周面に溝状の凹段部１３を設け、突部 １１に設けた横孔１４が円軸部８の外周面に臨む側で開口し、この横孔１４内に 球体を用いた係合子１５と、該係合子１５に常時円軸部８の外面に圧接する外方 へ向けての弾性を付勢するばね１６とを収納して形成され、凹段部１３は、ハン ドル１０を図２（Ｂ）の一点鎖線で示した中間位置にしたとき係合子１５が係合 するように位置が設定されている。The positioning mechanism 12 is provided with a groove-like recessed step portion 13 on the outer peripheral surface of the circular shaft portion 8, and a lateral hole 14 formed in the protrusion 11 is opened on the side facing the outer peripheral surface of the circular shaft portion 8. The lateral hole 14 is formed by accommodating a spherically-engaged engaging element 15 and a spring 16 which constantly presses the engaging element 15 against the outer surface of the circular shaft portion 8 and urges outward elasticity. The recessed step portion 13 is positioned such that the engaging element 15 engages when the handle 10 is moved to the intermediate position shown by the alternate long and short dash line in FIG.
【００１７】 この考案のガスコックは上記のような構成であり、各種ガス器具に取付け、バ ーナに対するガス供給の開閉を行なうものであり、レバーハンドル１０で閉子６ を全開の位置にした状態で弱火にしたいときは、レバーハンドル１０を図１（Ｂ ）の時計方向に回動させ、閉子６が弱火の中間位置になった時点で円軸部８の凹 段部１３が係合子１５に臨み、係合子１５が凹段部１３に落込むことにより、ハ ンドル１０の回動操作に抵抗が生じる。The gas cock of the present invention has the above-mentioned structure, is attached to various gas appliances and opens and closes the gas supply to the burner, and is in a state in which the lever handle 10 is set to the fully open position of the closure 6. To reduce the heat to low, rotate the lever handle 10 in the clockwise direction in FIG. 1 (B), and when the closure 6 reaches the intermediate position of the low heat, the concave step portion 13 of the circular shaft portion 8 is engaged with the engagement element 15. Then, the engaging element 15 falls into the concave step portion 13 to cause resistance to the rotating operation of the handle 10.
【００１８】 従って、凹段部１３に係合子１５が落込んだ時点でハンドル１０の回動を停止 すれば閉子６は図２（Ｂ）と図３（Ｂ）で示すように、ガス通路４に対する通孔 ７の連通量を絞り込んだ中間位置となり、バーナの弱火燃焼が得られる。Therefore, if the rotation of the handle 10 is stopped at the time when the engaging element 15 is dropped into the concave step portion 13, the closing element 6 is provided with a gas passage as shown in FIGS. 2 (B) and 3 (B). 4 is an intermediate position in which the amount of communication of the through hole 7 with respect to 4 is narrowed down, and low-burn combustion of the burner is obtained.
【００１９】 このように、位置決め機構１２の抵抗と感触により、閉子６の中間位置が簡単 かつ容易に設定でき、また、全開や全閉にする場合は、凹段部１３と係合子１５ の係合力に打勝つ力でレバーハンドル１０を回動させればよい。As described above, the intermediate position of the closure 6 can be easily and easily set by the resistance and the feel of the positioning mechanism 12, and in the case of fully opening or fully closing, the recessed step portion 13 and the engaging member 15 can be set. The lever handle 10 may be rotated by a force that overcomes the engagement force.
【００２０】[0020]
以上のように、この考案によると、ガスコックにおける閉子の中間位置への設 定が位置決め機構によって簡単かつ正確に行なえ、ガス器具のバーナ燃焼の弱火 設定時に、ガスの供給を止めてしまうような不都合の発生を防止することができ る。 As described above, according to the present invention, the position of the closure of the gas cock can be set easily and accurately by the positioning mechanism, and the gas supply is stopped when the burner combustion of the gas appliance is set to low heat. Inconvenience can be prevented.
