Abstract

PURPOSE: To realize a safety mechanism in which the riskiness of instantaneous ignition can be avoided even if an operator inserts a smoke pot to a loader while he erroneously remains ON an ignition switch in the ignition unit for an ammunition such as the smoke pot. CONSTITUTION: An ignition unit for a smoke pot 3 having a smoking unit 1 and an operating unit 5 has a rotary switch 8 in the ignition circuit of the unit 1, and a safety pin 9 inserted into or discharged from the loader 2 of the pot 3 in cooperation with the switch 8. Thus, even if the pot 3 is erroneously inserted, it cannot arrive at an ignition contact 4, and hence instantaneous ignition of the pot 3 can be avoided.

First of all, as shown in FIG.
At the time of replacement, the rotary switch 8 is turned to the off state by turning it to the right. At this time, the cam 10 pushes the safety pin 9 to the right, and the safety pin 9 is retracted from the insertion portion 2.
Next, as shown in FIGS. 2B and 2C, when the rotary switch 8 is turned to the ON state by turning it to the left side during operation, the cam 10 falls to the left side and the safety pin 9 is free from the cam 10. become. However, at the time of operation, the safety pin 9 has the spring 1 between the safety pin 9 and the safety pin holding metal fitting 11.
It is pushed to the left by 2 and protrudes into the insertion portion 2 as shown in FIG. However, when the smoke producing tube 3 is inserted into the insertion portion 2, it stops on the surface of the smoke producing tube 3 as shown in FIG.

First, the ignition switch 6 of the operation section 5 is turned off, or it is confirmed that the ignition switch 6 is off, and the rotary switch 8 of the smoke emitting section 1 is set to the exchange (off) position. As a result, the electric circuit for ignition is cut at two points, and the safety pin 9 is retracted from the smoke tube insertion portion 2 (FIG. 2 (a)). Then, in this state, the smoke producing tube 3 is inserted into the inserting portion 2.

By the way, in the above operation procedure, even if the ignition switch 6 of the first operation portion 5 is neglected to be turned off, the rotary switch 8 of the smoke emitting portion 1 is set to the exchange (off) position. The ignition electrical circuit is disconnected. Therefore, it is possible to prevent the risk of ignition when the smoke tube 3 is inserted. Further, when the rotary switch 8 is in the operating (ON) state, the safety pin 9 projects into the insertion portion 2 of the smoke emitting tube 3, so that the smoke emission tube 3 is blocked by the safety pin 9 and the insertion portion is inserted. The ignition contact 4 on the bottom of 2 cannot be reached. That is, when the electric circuit is in the ON state, the smoke tube 3 cannot be mechanically inserted by the safety pin 9,
It can only be inserted if the electrical circuit is in the off state. As a result, suddenly when the smoke tube 3 is inserted,
The risk of ignition is prevented.

By the way, in the above operation procedure, even if the ignition switch 6 of the first operation portion 5 is neglected to be turned off, the rotary switch 8 of the smoke emitting portion 1 is set to the exchange (off) position. The ignition electrical circuit is disconnected. Therefore, the risk of ignition when the smoke tube 3 is inserted can be prevented. Further, when the rotary switch 8 is in the operation (ON) state, the safety pin 9 is not inserted into the smoke producing tube 3.
Since projects into N parts 2, flares 3 is blocked in the safety pin 9, until the ignition contact 4 on the bottom of 挿Ten portion 2 can not be reached. That is, when the electrical circuit is in the ON state, the flares 3 can not be mechanically 挿Ten by safety pin 9, the electrical circuit only when in the off state, that you can 挿Ten <br/> Become. This prevents the risk of sudden ignition when the smoke tube 3 is inserted .

1. A safety mechanism of a device for igniting a pyrotechnic article comprising a smoke emitting portion and an operating portion, wherein a rotary switch is provided in an ignition circuit of the smoke emitting portion, and a smoke tube is inserted in conjunction with the rotary switch. A safety pin is provided for moving in and out of the portion, and when the rotary switch is turned on, the safety pin is prevented from protruding into the insertion portion and preventing the smoke tube from coming into contact with an ignition contact in the insertion portion. A safety mechanism for a device that ignites a pyrotechnic product.
