  Hereinafter, a rocket fireworks launching apparatus 1 according to an embodiment of the present invention will be described with reference to the drawings.

  The rocket fireworks launching device 1 in this embodiment has a shape like a gun that can be held with one hand. As shown in FIG. 1, a cylinder body 2 into which a rocket fireworks 8 is inserted, and the cylinder body 2 are provided. A grip portion 5 that can be gripped in a state directed in a specific direction is provided, and an ignition device 7 can be detachably attached to the inside of the grip portion 5. Characteristically, the rocket fireworks 8 can be inserted from the rear side of the cylinder main body 2, and when inserting the rocket fireworks 8, the rocket fireworks 8 rotate downward like a check valve, and the rocket fireworks 8 The first shutter 3 for returning the inner space of the cylinder main body 2 to be closed after passing the combustion part 81 in front of is provided. In addition to this, when the ignition wire 82 is ignited, the ignition wire 82 and the ignition device 7 are opened to allow ignition, and after the ignition wire 82 is ignited, the ignition device 7 and the ignition wire are ignited. The second shutter 6 is provided so as to close the space between the ignition device 7 and the ignition device 7 can be protected. Hereinafter, an embodiment of the present invention will be described in detail.

  First, the cylinder body 2 is constituted by a cylindrical metal member, and is configured so that a single rocket fireworks 8 can be inserted in the axial direction. A circular insertion port 21 is provided behind the tube main body 2 so that the rocket fireworks 8 can be inserted. The rocket fireworks 8 can be inserted from the insertion port 21. The insertion port 21 is configured to have a labyrinth structure so that the injection flame of the inserted rocket fireworks 8 can be prevented from leaking backward.

  A first shutter 3 is provided on the rear side of the cylinder body 2. As shown in FIG. 3A, the first shutter 3 is configured such that when the rocket fireworks 8 are inserted from the insertion port 21, the upper end portion is pivoted downward about the pivot shaft 31 to cause rocket fireworks. 8, and when the combustion unit 81 is passed, the upper end portion is again rotated upward by the pressing force of the spring 32 as shown in FIG. The main body 2 is configured to be closed. Here, the first shutter 3 is inclined so as to constitute a check valve, whereby the rocket fireworks 8 can be inserted from the rear. Further, as shown in FIG. 2, a recess 33 is formed at the upper end of the first shutter 3 so that the shaft 83 of the rocket fireworks 8 can pass therethrough. The concave portion 33 is formed so that a slight gap can be formed between the first shutter 3 and the shaft 83 when the first shutter 3 is closed, so that the shaft 83 can be smoothly moved when the rocket fireworks 8 are fired. I try to pull it out. The jet flame leaking from the concave portion 33 flows backward to some extent, but the leak of the jet flame is suppressed by the labyrinth structure provided in the insertion port 21.

  In the inclined portion on the front surface side of the first shutter 3, a guide portion 4 that guides the lead wire 82 of the rocket fireworks 8 toward the ignition device 7 is provided. The first shutter 3 is provided in an inclined state. By inserting the rocket fireworks 8 from the rear and pulling back (the state shown in FIG. 4C), the lead wire 82 can be separated downward along the inclined surface. I am doing so. At this time, since it is necessary to bring the igniting wire 82 as close to the ignition device 7 as possible, here, as shown in FIG. And the left and right wall surfaces 41 are formed so as to be narrower toward the lower side so that the front end portion is positioned closer to the ignition device 7.

  Next, the structure of the ignition device 7 will be described.

  The ignition device 7 is constituted by a lighter that is detachably accommodated in the grip portion 5, and can be ignited by the fire output from the tip portion thereof. When this lighter is mounted, the nozzle portion is inserted first from the opened portion on the front side of the grip portion 5, and then the main body portion is pushed in. Then, the lead wire 82 is ignited by pulling the lever 71 provided so as to be exposed from the grip portion 5 with the index finger. The tip position of the nozzle of the ignition device 7 is provided at a position close to the igniting wire 82, so that the igniting wire 82 can be ignited even with a small flame.

  In this way, when the nozzle of the ignition device 7 is brought close to the lead wire 82, the resin part of the nozzle or lighter is melted by the flame at the time of ignition, or metal powder adheres to the vicinity of the nozzle by the jet flame, It may rust or not discharge. Therefore, here, the second shutter 6 is provided in which the space between the nozzle and the conductive wire 82 is closed after ignition of the conductive wire 82.

  As shown in FIG. 4 (d), the second shutter 6 allows a gap between the ignition device 7 and the lead wire 82 to be opened by pressing a lever 61 that protrudes to the rear portion of the grip portion 5. The clearance 61 is configured to be closed by releasing the lever 61. At this time, since the lever 61 is provided behind the grip portion 5 on the side opposite to the lever 71 of the ignition device 7, the ignition operation and the opening of the second shutter 6 can be performed simultaneously with the index finger and the thumb. Become. The second shutter 6 is provided so as to be rotatable about a rotation shaft 62, and can always block the gap between the lead wire 82 and the ignition device 7 by the force of the spring 63.

  Next, a method of using the rocket fireworks launching device 1 configured as described above will be described.

  First, when using the rocket fireworks launching apparatus 1, one rocket firework 8 is inserted from the insertion port 21 at the rear of the tube body 2 (FIG. 1). Then, as shown in FIG. 3A, the combustion part 81 of the rocket fireworks 8 hits the back side of the first shutter 3 and pushes down the upper end part of the first shutter 3 against the pressing force of the spring 32. It becomes like this. Further, when the rocket fireworks 8 are pushed in from this state, the combustion portion 81 of the rocket fireworks 8 passes through the first shutter 3 and rotates so that the first shutter 3 returns to the original state by the force of the spring 32 ( FIG. 3 (b)). As a result, the rear portion of the cylinder body 2 is blocked by the first shutter 3. At this time, the shaft 83 of the inserted rocket fireworks 8 is positioned inside the recess 33 provided at the upper end of the first shutter 3 as shown in FIG.

  Then, in this state, the shaft 83 of the rocket fireworks 8 is pulled back (FIG. 4C). Then, the conducting wire 82 provided behind the combustion unit 81 is separated downward along the inclined surface of the first shutter 3 and is guided to the channel-shaped guide unit 4. And the front-end | tip part of the conducting wire 82 is positioned in the vicinity of the ignition device 7 by the guidance | induction part 4 provided so that the mutual wall surface 41 might become narrow toward the downward direction. Thus, the rocket fireworks 8 can be fired.

  When the rocket fireworks 8 are fired in this state, the muzzle is directed in the firing direction, and the lever 61 provided behind the grip portion 5 is pressed (FIG. 4D). Then, the second shutter 6 is rotated to open the space between the ignition device 7 and the igniting wire 82, so that the ignition can be performed. Then, when the lever 71 of the ignition device 7 is operated in this state, a flame is output, and the igniting wire 82 is ignited. At this time, by releasing the lever 61 provided on the rear side of the grip portion 5, the second shutter 6 is closed and the ignition device 7 is protected.

  When this fire reaches the combustion part 81 via the lead wire 82, the gunpowder in the inside is ignited, and the rocket fireworks 8 can be launched in the firing direction (FIG. 5). At this time, the jet flame is blocked from leaking backward by the first shutter 3, and from the leak to the ignition device 7 by the second shutter 6.

  As described above, according to the above-described embodiment, in the rocket fireworks launching apparatus 1 in which the rocket fireworks 8 loaded in the cylinder main body 2 are ignited so that the rocket fireworks 8 are fired from the cylinder main body 2. Since the shutters (first shutter 3 and second shutter 6) that can be opened and closed to prevent leakage of the jet flame from the rocket fireworks 8 inserted into the main body 2 are provided, when inserting the rocket fireworks 8, The first shutter 3 can be opened for easy insertion, and at the time of ignition, the first shutter 3 can be closed to prevent the injection flame from leaking.

  In addition, an insertion port 21 that allows the rocket fireworks 8 to be inserted is provided at the rear of the cylinder body 2, and opens when the rocket fireworks 8 are inserted from the rear of the cylinder body 2. Since the first shutter 3 that closes when passing is provided, the rocket fireworks 8 can be easily inserted by opening and closing the first shutter 3 simply by inserting the rocket fireworks 8 from the rear.

  In addition, since the second shutter 6 is provided to divide the rocket fireworks 8 and the ignition device 7 so as to be openable and closable, it is possible to prevent the injection flame from being applied to the ignition device 7. It is possible to prevent the metal powder from adhering and rusting, and the lighter resin from melting.

  Furthermore, when the first shutter 3 is provided, since the lead wire 82 can be separated by inserting the rocket fireworks 8 and then pulling back, the leakage of the injection flame can be prevented and the lead wire 82 can be separated at the same time. It becomes possible to easily ignite the separated lead wire 82.

  In addition, according to this invention, it can implement in a various aspect, without being limited to the said embodiment.
