Description

Technical Field

[0001] The present invention relates to a primer cartridge for holding bullets loaded into a toy gun, and particularly relates to a highly safe primer cartridge for a toy gun that suppresses the dropout of gunpowder during firing and enables reliable ignition of the gunpowder to generate a cracking sound like that of a real gun.

Background Art

[0002] Conventionally, many cartridges for toy guns with various devices have been used, and cartridges with various structures have been developed and used.

[0003] [[ID=1 6]]The cartridges for toy guns have various structures, such as a structure in which a toy bullet is enclosed inside, or a structure in which only gunpowder is enclosed and the bullet is separated and loaded into the gun. When using gunpowder, since the power of the bullet increases and the possibility of having a killing ability becomes higher, the gunpowder and the bullet are arranged separately, and the gunpowder is used to generate a cracking sound and the smell of gunpowder.

[0004] Such a toy gun using gunpowder requires high safety, such as suppressing the dropout of gunpowder and accidental firing, and it is desirable that the gunpowder is firmly held.

[0005] As a technology related to such a primer cartridge for a toy gun, there is Japanese Patent No. 5167434. Here, it is a technology related to a safe toy gun in which the gun body and the chamber are blocked, and a structure in which a cartridge without a bullet is loaded into a receiver not connected to the gun body, or a structure in which a blocking wall for separating the gun body and the cartridge is provided in the middle between the gun body side and the cartridge side is disclosed. According to this technology, it is certainly possible to maintain high reproducibility of the cartridge shape and ensure the reproducibility of real gun operation and the safety required for a toy. However, there is an inherent problem that the gunpowder in the cartridge may drop out during firing or the gunpowder may not be reliably ignited.

[0006] When constructing toy guns that enhance their appeal by enclosing gunpowder in a cartridge and igniting it, a stable ignition mechanism is necessary. There has been a demand for the development of a highly safe ignition cartridge for toy guns that solves the problems mentioned above and prevents situations where the gunpowder in the cartridge falls out during ignition or fails to ignite reliably. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Patent No. 5167434 [Disclosure of the Invention] [Problems that the invention aims to solve]

[0008] To solve the above problems, the present invention aims to provide a highly safe firing cartridge for toy guns that holds bullets loaded into a toy gun, and in particular suppresses the detachment of gunpowder during firing, while reliably igniting the gunpowder and producing a popping sound similar to that of a real gun. [Means for solving the problem]

[0009] To achieve the above objective, the present invention provides a firing cartridge that can be loaded into a toy gun, comprising: a hollow cylindrical cartridge body; a cylindrical inner part housed within the cartridge body so as to be movable back and forth; the cartridge body comprising: an installation portion for installing and fixing the inner part and one or more first cap gunpowder components; a striking portion that seals the inner part within the cartridge body and ignites upon impact; and a top portion having a circular first opening provided at the end opposite the striking portion to prevent the inner part from falling out; the inner part is installed and fixed on the top portion side of the installation portion, It is on the outside of the inner layer.The first cap gunpowder is placed and fixed on the side of the installation portion that is struck, the inner part is in contact with the first cap gunpowder, and the first cap gunpowder is in contact with the struck portion, the inner part consists of an inner cap having a cylindrical internal space for enclosing one or more second cap gunpowders, and an inner body having thickness in the screwing direction for screwing into the inner cap to seal the second cap gunpowder, the inner cap has a second opening at the end opposite to the part into which the inner body is screwed. Furthermore, the inner body is configured such that a third opening is cut through it from the internal space side of the inner cap toward the side of the part to be struck. When the part to be struck is struck, the first cap gunpowder ignites, and the pressure of the gas generated causes the cartridge body to retract, moving the inner part inside the cartridge body to the top. At the same time, the ignition ignites the second cap gunpowder through the third opening, and the resulting smoke and popping sound are generated from the first opening at the top through the second opening.

[0010] Furthermore, the inner body is configured to be fixed to the installation part of the cartridge body and to have an O-ring fitted around it to prevent gas leakage. [Effects of the Invention]

[0011] As the present invention has the configuration described in detail above, it has the following effects. 1. The inner body is screwed into the inner cap to seal the second cap gunpowder, preventing the gunpowder from falling out during ignition. Furthermore, the ignition of the first cap gunpowder causes the cartridge body to retract (the inner body moves to the top), and at the same time, the ignition ignites the second cap gunpowder, producing smoke and a popping sound. This configuration allows for the reproduction of realistic and powerful smoke and popping sounds, enhancing the playability and hobby aspect. 2. By providing an O-ring in the inner body, it is possible to provide a highly safe ignition cartridge that prevents gas from flowing back due to ignition. [Best Mode for Carrying Out the Invention]

[0012] The ignition cartridge according to the present invention will be described in detail below based on the embodiments shown in the drawings. Figure 1 is a side cross-sectional view of the ignition cartridge according to the present invention, and Figure 2 is an exploded perspective view of the inner part. Figure 3 is a side cross-sectional view of the ignition cartridge with the firing pin attached, and Figure 4 is a side cross-sectional view of the ignition cartridge after ignition.

[0013] As shown in Figure 1, the ignition cartridge 1 of the present invention consists of a cartridge body 100 and an inner part 200. It suppresses the detachment of gunpowder during ignition and ensures reliable ignition of the gunpowder, producing a popping sound similar to that of a real gun. It is a safe and highly hobby-oriented ignition cartridge that can be loaded into toy guns.

[0014] The cartridge body 100 is a component that constitutes the housing of the ignition cartridge 1. As shown in Figure 1, it is a hollow cylindrical member, with one end of the cylinder sealed and the other end having an opening (first opening 132). Since the gunpowder ignites inside the cartridge body 100, it is desirable that it be made of a sturdy material and be thick-walled.

[0015] The inner 200 is a component for sealing and holding gunpowder inside, and is housed within the cartridge body 100 so as to be movable back and forth. The inner 200 is positioned within the cylindrical hollow of the cartridge body 100, and in this embodiment, it is a cylindrical component with approximately the same diameter as the hollow of the cartridge body 100. In this embodiment, as shown in Figures 3 and 4, when the firing cartridge 1 is loaded into the gun, the elongated pipe-shaped firing pin 30 attached to the barrel is inserted into the first opening 132, and the end of the firing pin 30 comes into close contact with the inner 200.

[0016] As shown in Figure 1, the cartridge body 100 comprises an installation section 110, a striking section 120, and a top section 130. The installation section 110 is a component for installing and fixing the inner 200 and the first cap gunpowder 10 inside the cartridge body 100. It has a cylindrical space inside, and the inner 200 and the first cap gunpowder 10 are installed within this space. As shown in Figure 1, the internal space of the installation section 110 is longer than the installation length of the inner 200 and the first cap gunpowder 10.

[0017] The first cap gunpowder 10, as described later, is a component that generates firepower to ignite the second cap gunpowder 20, as described later, by using the pressure of the gas produced by ignition to retract the cartridge body 100 (the inner 200, which is in close contact with the firing pin 30, moves within the internal space of the installation section 110). One or more first cap gunpowder 10 are installed. In Figure 1, one first cap gunpowder 10 is installed in the installation section 110, but this is not the only configuration. It is also possible to install two or more first cap gunpowder 10 to increase the power of the ignition and enhance the hobby aspect.

[0018] The striking part 120 is sealed inside the cartridge body 100 to prevent the inner 200 from falling out, and is an ignition primer that is struck by a striking member provided on the toy gun loaded with the ignition cartridge 1 when fired. In this embodiment, the toy gun loaded with the ignition cartridge 1 has a member that strikes the end of the ignition cartridge 1 with strong force. As shown in Figure 1, the striking part 120, which is the ignition primer, is installed at the end of the ignition cartridge 1, and when this part is struck, the striking part 120, which is the ignition primer, ignites and the first cap gunpowder 10 that is in contact with it ignites, generating a flame and gas and creating a pressing force.

[0019] The top head part 130 is a member that serves as a lid to prevent the inner part 200 from falling off the cartridge body 100. As shown in FIG. 1, it is provided at the end on the side facing the struck part 120 of the cartridge body 100. The top head part 130 has a structure with a circular first opening 132. The firing pin 30 attached to the gun body is inserted into this opening, and the smoke and bursting sound generated by the second cap powder 20 described later are led to the outside through the pipe-shaped firing pin 30.

[0020] The arrangement of the above-mentioned members will be described. As shown in FIG. 1, the inner part 200 is installed and fixed on the side of the top head part 130 of the installation part 110 of the cartridge body 100. Also, one or more first cap powders 10 are placed and fixed on the side of the struck part 120 of the installation part 110.

[0021] The inner part 200 abuts against the first cap powder 10. Furthermore, the first cap powder 10 is configured to abut against the struck part 120. Thus, when the struck part 120 is struck, the struck part 120 catches fire and ignites the first cap powder 10 that abuts against it. At the same time, the generated gas presses the inner part 200. As shown in FIG. 4, the cartridge body 100 moves backward and the inner part 200 moves inside the installation part 110 toward the top head part 130 side.

[0022] As shown in FIGS. 1 and 2, in this embodiment, the inner part 200 is composed of an inner cap 210 and an inner body 220. The inner cap 210 is a member having a cylindrical inner space, and one or more second cap powders 20 are enclosed in this inner space. In this embodiment, as shown in FIG. 1, two second cap powders 20 are enclosed back to back, but it is not limited to this configuration. Depending on the size of the firing cartridge 1 or to adjust the power of firing, it is possible to appropriately select to have one second cap powder 20 or enclose more second cap powders 20.

[0023] The inner body 220 is a lid-shaped member for screwing and installing on the inner cap 210 to seal the second cap gunpowder 20, and is configured to screw onto the inner cap 210 to securely enclose the second cap gunpowder 20. The inner body 220 has a thickness in its screwing direction. This makes it possible to suppress a situation where the inner body 220 is damaged due to the ignition of the first cap gunpowder 10.

[0024] As shown in FIGS. 1 and 2, the inner cap 210 is configured such that a second opening 212 is provided at an end portion facing the portion where the inner body 220 is screwed. Further, as shown in FIG. 1, the inner body 220 is configured such that a third opening 222 is drilled through from the inner space side of the inner cap 210 toward the struck portion 120 side. That is, the ignition from the first cap gunpowder 10 installed outside the inner 200 is transmitted into the inner 200, and the smoke and rupture sound generated by the ignition of the second cap gunpowder 20 enclosed inside the inner 200 are released to the outside of the inner 200.

[0025] Next, the operation of the ignition cartridge 1 will be described. As shown in FIG. 3, when a striking member that operates during firing provided in the toy gun strikes the struck portion 120, the first cap gunpowder 10 is ignited through the ignition of the struck portion 120, which is an ignition primer. Due to the pressing force of the gas generated thereby, as shown in FIG. 4, the cartridge body retreats due to the pressing force, and the inner 200 moves within the installation portion 110 of the cartridge body 100 up to the top portion 130. At this time, since the diameter of the inner cap 210 is larger than the diameter of the first opening 132, the inner 200 does not escape to the outside of the ignition cartridge 1. In addition to making the inner cap 210 have a larger diameter than the first opening 132, it is also possible to provide a locking portion 214 on the inner cap 210 and configure the locking portion 214 to lock to the first opening 132 to prevent the inner 200 from escaping to the outside of the ignition cartridge 1.

[0026] Furthermore, simultaneously with the ignition of the first cap charge 10, the ignition of the first cap charge 10 ignites the second cap charge 20 through the third opening 222. The resulting smoke and popping sound are then released to the outside through the second opening 212 and the first opening 132 of the top portion 130 via the pipe-shaped firing pin 30.

[0027] As a result, it is possible to reproduce realistic and powerful smoke and explosion sounds, enhancing the playability and hobby aspect. Furthermore, when the first cap gunpowder 10 is fired, the cartridge body 100 retracts and the inner part 200 moves to the top, making the impact and vibration transmitted to the hand when fired more realistic, similar to firing live ammunition, thus creating a more hobby-oriented firing cartridge 1.

[0028] By adopting the above configuration, it has become possible to provide a highly safe and hobby-grade firing cartridge for toy guns that suppresses situations where the gunpowder inside the cartridge falls out during ignition or where the gunpowder cannot be reliably ignited.

[0029] In this embodiment, the inner body 220 is configured to have an O-ring 224 fitted around it, as shown in Figures 1 and 2. The O-ring 224 surrounds the inner body 220 and is a component that abuts against the cylindrical mounting portion 110 of the cartridge body 100. This makes it possible to stably fix the inner 200 to the mounting portion 110 of the cartridge body 100, prevent leakage of gas generated from the ignited gunpowder, and prevent backflow of gas due to ignition, thereby providing a highly safe ignition cartridge.
