【作用】[Action]

セットレバー(2)を下方へ押し下げると、回転軸(3)を支点として引き上 げレバー(4)が上方へ回転し、これに伴い、鎖(5)でつながっている引っか け棒(8)、金属球(9)が引き上げられ、コイルバネ(11)が伸びる。引っ かけ棒(8)の上部にある止めヅメ(7)の下端が止め板(6)の上端を越える とここに引っかかり、コイルバネ(11)は伸びた状態で固定される。この時、 セットレバー(2)は上方へ押し上げて、鎖(5)をたるませておく。この状態 で、ガスは中空管(1)の上方から下方に向け通過する。地震があると、金属球 (9)が上下左右に振動し、引っかけ棒(8)は、止め板(6)の下端をてこの 支点として動き、この動きがある程度を越えると、止めヅメ(7)が止め板(6 )から外れ、金属球(9)はコイルバネ(11)に引かれるまま下方へ落下する 。そして、金属球(9)は自重、バネの引力及び上方からのガスの圧力によりゴ ムパッキン(10)に密着して、ガスの経路を遮断することができる。 When the set lever (2) is pushed downward, the pull-up lever (4) rotates upward with the rotating shaft (3) as a fulcrum, and accordingly, the catch bar (8) connected by the chain (5). ), The metal ball (9) is pulled up, and the coil spring (11) extends. When the lower end of the stopper claw (7) on the upper part of the hooking rod (8) exceeds the upper end of the stopper plate (6), it is caught here and the coil spring (11) is fixed in an extended state. At this time, the set lever (2) is pushed upward to slacken the chain (5). In this state, the gas passes downward from above the hollow tube (1). In the event of an earthquake, the metal ball (9) vibrates vertically and horizontally, and the hooking rod (8) moves with the lower end of the stop plate (6) as the lever fulcrum. ) Is disengaged from the stop plate (6), and the metal ball (9) falls downward while being pulled by the coil spring (11). Then, the metal ball (9) is brought into close contact with the rubber packing (10) by its own weight, the attractive force of the spring and the pressure of the gas from above, and the path of the gas can be blocked.

【実施例】【Example】

以下、本案の実施例について説明する。 (イ)中空管(1)の上部に密閉性を保った回転軸(3)を設け、回転軸(3) を中心に中空管(1)の外部にセットレバー(2)、内部に引き上げレバー (4)を設ける。 (ロ)中空管(1)の内部に止め板(6)を設ける。 (ハ)上部に円錐状の止めヅメ(7)を設けた引っかけ棒(8)を金属球(9) の上端に、接続部が自由に回転するように接続し、金属球(9)の下部にコ イルバネ(11)の上端をを接続する。 (ニ)引き上げレバー(4)の先端に鎖(5)を装着し、鎖(5)のもう一方の 端を、止めヅメ(7)の上端に接続する。 (ホ)コイルバネ(11)の下端を中空管(1)の下部に接続する。 (ヘ)金属球(9)と接触する中空管(1)の下部にゴムパッキン(10)を装 着する。 本案は以上のような構造で、これを使用するときは、セットレバー(2)を下 方に押し下げ、止めヅメ(7)の下端を、止め板(6)の上端に引っかける。こ のときコイルバネ(11)は伸びた状態に固定される。この状態でガスは中空管 (1)の上方から下方へ向けて通過する。地震などによる振動があると、金属球 (9)が上下左右に振動し、引っかけ棒(8)が、止め板(6)の下端をてこの 支点として振れる。この時、金属球(9)の動きがある程度を越えると、止めヅ メ(7)の下端が止め板(6)からはずれ、金属球(9)はコイルバネ(11) に引かれるまま下方に落下し、自重、バネの引力及び上方からのガスの圧力によ りゴムパッキン(10)と密着して、ガスの経路を遮断する。 なお、本考案は、従来のガス器具の内部に取り付けてもよいし、単体の装置と して既に使用されているガス器具と、ガスの元栓との中間位置に取り付けて使用 することも可能である。 Hereinafter, examples of the present invention will be described. (A) A rotary shaft (3) that maintains hermeticity is provided above the hollow pipe (1), and a set lever (2) is provided inside the hollow pipe (1) around the rotary shaft (3) and inside the hollow pipe (1). Provide a lifting lever (4). (B) A stopper plate (6) is provided inside the hollow tube (1). (C) A hook rod (8) having a conical stopper (7) at the top is connected to the upper end of the metal ball (9) so that the connecting portion can rotate freely, and the lower part of the metal ball (9) is connected. Connect the upper end of the coil spring (11) to. (D) Attach the chain (5) to the tip of the lifting lever (4), and connect the other end of the chain (5) to the upper end of the stopper claw (7). (E) The lower end of the coil spring (11) is connected to the lower part of the hollow tube (1). (F) A rubber packing (10) is attached to the lower part of the hollow tube (1) that comes into contact with the metal balls (9). The present invention has the structure as described above, and when using it, the set lever (2) is pushed downward and the lower end of the stopper claw (7) is hooked on the upper end of the stopper plate (6). At this time, the coil spring (11) is fixed in an extended state. In this state, the gas passes from above the hollow tube (1) to below. When there is a vibration due to an earthquake or the like, the metal ball (9) vibrates vertically and horizontally, and the hook rod (8) swings with the lower end of the stopper plate (6) as a lever fulcrum. At this time, if the movement of the metal ball (9) exceeds a certain amount, the lower end of the stopper claw (7) is disengaged from the stopper plate (6), and the metal ball (9) is dropped downward while being pulled by the coil spring (11). Then, due to its own weight, the attractive force of the spring, and the pressure of the gas from above, it makes close contact with the rubber packing (10) and shuts off the gas path. The present invention may be installed inside a conventional gas appliance, or may be installed at an intermediate position between a gas appliance that has already been used as a single device and the gas main tap. is there.
