この考案は、火薬の燃焼により生じるガス圧に
よつて収縮状態にあるベローズを伸長側に膨出さ
せ、その膨出による押圧力を利用して行なう駆動
装置に関する。[Detailed Description of the Invention] This invention relates to a drive device that bulges a bellows in a contracted state to the extension side by gas pressure generated by combustion of gunpowder, and uses the pressing force caused by the bulge.

つた。 Conventionally, this type of drive device has been used, for example, when moving an object holding the detonator in a fuse to align the detonator with the detonator, and structurally, it has been used, for example, in Figure 1 a, b or Figure 1. Structures as shown in Figures 2a and 2b are known. However, in the dimple type shown in FIG.
Further, the bellows type shown in FIG. 2 has the advantage that the amount of protrusion of the driving part 2a is large, but the problem is that it is difficult to obtain an effective driving force because the direction in which the protruding driving part 2a protrudes tends to be unstable. The point was hot.
この考案は、このような問題点に対処してなさ

もとで、ベローズ方式による有効な駆動力が安定

にある。 This invention was developed in response to these problems, and its features include a drive device that uses a bellows method to stably obtain effective driving force with an extremely simple configuration. It is about providing.
次に、この考案を図面に基づいて説明する。 Next, this invention will be explained based on the drawings.

９が冠着状に被せてある。 FIG. 3 shows a cross section of an embodiment of the drive device, and 3 is a case accommodating the gunpowder 4, and this case 3 includes a base part 6 containing an ignition part 5, and a front part from the periphery of this base part 6. A bellows cap 9 is placed over the cylinder part 7 so as to close the opening 8 thereof.

なお、点火部５はヒータにて構成してあり、リー
ド線１０を介して点火電流が供給される。 In the bellows cap 9, a folded bellows portion 9a is located on the outer periphery of the cylinder portion 7, and a base portion 9b thereof is fixed to the base portion 6 of the case 3. Therefore, the cylinder portion 7 extends as much as possible to a position where the bellows portion 9a comes into contact with the inner surface of the cap portion 9c in the folded state.
Incidentally, the ignition section 5 is composed of a heater, and an ignition current is supplied through a lead wire 10.
この考案の駆動装置は上述の如く構成して、い

ケース３を構成するシリンダ部７でガイド可能に
保持してあるから、点火部５による点火で火薬４
が燃焼すると、その燃焼ガス圧によつて膨出する
ベローズキヤツプ９がシリンダ部７に沿つて開口
８方向に撓みを生じることなく適確に突出でき
る。第４図がこの状態を示す。 The drive device of this invention is constructed as described above, and the so-called folded bellows cap 9 is held so that it can be guided by the cylinder part 7 that constitutes the case 3, so that when the ignition part 5 ignites the gunpowder
When the bellows cap 9 is combusted, the bellows cap 9, which expands due to the pressure of the combustion gas, can properly protrude along the cylinder portion 7 in the direction of the opening 8 without being bent. FIG. 4 shows this state.
また、ベローズキヤツプ９にはシリンダ部７が
対設してあるので、ベローズ部９ａが撓みやすい
機能を有していても、火薬４の燃焼ガス圧による
ベローズキヤツプ９の膨出は折りたたまれている
ベローズ部９ａが径方向に加圧されることがなく
一定方向に膨出できる。このため、膨出されるベ
ローズキヤツプ９はみだりな撓みを生じることが
ないので、膨出による押圧力が有効に得られる。 Further, since the cylinder portion 7 is provided opposite to the bellows cap 9, even if the bellows portion 9a has a function of being easily bent, the bellows cap 9 is not bulged due to the combustion gas pressure of the gunpowder 4. The bellows portion 9a can bulge in a fixed direction without being pressurized in the radial direction. Therefore, the bellows cap 9 that is bulged out will not be unnecessarily bent, so that the pressing force due to the bulging can be effectively obtained.

の信頼性を大きく高めることができる。 Therefore, according to this invention, the gas pressure of the gunpowder 4 burning in the case 3 can be increased by the pressing force P caused by the expansion of the bellows cap 9 while maintaining the directionality in a certain direction by the cylinder part 7. Therefore, the pressing driving force of the cap portion 9c of the bellows cap 9 can be effectively generated with minimal waste. Therefore, the driving position of the cap portion 9c can be expanded to a reliable extended position with an appropriate driving force, and the reliability of this type of driving device can be greatly improved.
