[Problems to be solved by the device]

上記のような従来の消火器では、レバー動作板（11）と
封印シール（12）とが別々のものであるから、別々に製
作しなければならないは勿論、組立工程においても別々
に組立なければならず、組立作業性が悪く、コストアッ
プになるという問題点があった。In the conventional fire extinguisher as described above, since the lever operation plate (11) and the seal (12) are separate, they must be manufactured separately, and also in the assembly process. As a result, the assembly workability is poor and the cost is increased.

この考案はかかる問題点を解消するためになされたもの
で、レバー動作板に封印シールの働きを兼ねさせること
により部品点数の削減による組立作業性の向上とコスト
ダウンが図れる消火器を得ることを目的とする。The present invention has been made to solve such a problem, and it is possible to obtain a fire extinguisher capable of improving the assembly workability and reducing the cost by reducing the number of parts by making the lever operation plate also serve as a seal. To aim.

[Means for solving the problem]

上記目的を達成するために、この考案に係る消火器は、
レバー動作板に封印片を一体樹脂成形により形成したも
のである。In order to achieve the above object, a fire extinguisher according to the present invention,
A sealing piece is formed on the lever operation plate by integral resin molding.

[Action]

この考案においては、レバー動作板に封印片を一体成形
したので、封印シールが不要となり、レバー動作板の装
着のみで封印も行える。In this invention, since the sealing piece is integrally formed on the lever operation plate, the seal is not required, and the sealing can be performed only by mounting the lever operation plate.

において、（11A）はレバー動作板で、上方に延びて直
角に屈曲する封印片（11b）を有している。（11c）は封
印片（11b）の折れを容易、確実にするための溝であ
る。このレバー動作板（11A）は樹脂成形され、突起（1
1a）と封印片（11b）と溝（11c）とが形成されている。An embodiment of the present invention will be described below with reference to FIGS. Fig. 1 is a front view of the main part, and Fig. 2 is a line II- in Fig. 1.
II is a partial view seen from II, FIG. 3 is a partial view seen from line III-III in FIG. 1, FIG. 4 is a front view of the lever operation plate of FIG. 1, FIG. 5 is a right side view of FIG. FIG. 6 is a rear view of FIG. 4, and FIG. 7 is a plan view of FIG. 5. The same or corresponding parts as those of the conventional device are designated by the same reference numerals and the description thereof will be omitted. In the figure, (11A) is a lever operation plate having a sealing piece (11b) extending upward and bent at a right angle. (11c) is a groove for easily and surely breaking the sealing piece (11b). This lever operating plate (11A) is molded with resin and has a protrusion (1
1a), a sealing piece (11b) and a groove (11c) are formed.

このようにレバー動作板（11A）に封印片（11b）を一体
成形しておくと、レバー動作板（11A）を突起（11a）に
より提手レバー（６）に装着すると同時に封印片（11
b）が安全ピン（10）の封印の作用をするので、従来の
ような封印シール（12）が不要となる。そして、安全ピ
ン（10）を抜くと、封印片（11b）が溝（11c）の部分で
折れて飛ぶか折曲し、従来と同様に突起（11a）が折れ
ることによりレバー動作板（11A）が落下する。When the sealing piece (11b) is integrally formed on the lever operation plate (11A) in this way, the lever operation plate (11A) is attached to the handle lever (6) by the protrusion (11a) and at the same time the sealing piece (11A) is attached.
Since b) acts as a seal for the safety pin (10), the conventional seal (12) is not required. Then, when the safety pin (10) is pulled out, the sealing piece (11b) folds at the groove (11c) and flies or bends, and the protrusion (11a) folds as in the conventional case, so that the lever operation plate (11A) Falls.

[Effect of device]

以上のように、この考案によればレバー動作板に封印シ
ールの働きを兼ねさせたので、部品点数が削減されて組
立作業性が向上すると共にコストダウンが図れるという
効果が得られる。As described above, according to the present invention, since the lever operating plate also functions as the seal, the number of parts can be reduced, the assembling workability can be improved, and the cost can be reduced.
