Description

Firing assembly of a simulated gun using compressed air {A FIRING ASSEMBLY OF A SIMULATED GUN USING COMPRESSED AIR}

The present invention relates to a firing assembly for a simulated gun using compressed air. Specifically, the insufficient parts of the operation of toy guns using the pressure of existing gas or pressurized air are improved by structural improvement, so that the external appearance is the same as that of an actual gun. This relates to a firing assembly of a simulated firearm using compressed air that generates a similar level of operation and sensation.

Currently, mock guns for training used by organizations such as the military or police, or simulated guns used for leisure sports in the private sector, are broadly classified into two categories based on the energy source of firing.

One way to classify the above simulated firearms is the electric type, which operates the piston's retraction stroke using a motor and then uses an elastic body to generate air pressure inside the piston cylinder to fire a simulated bullet with that air pressure. The other method is the liquefied type. There is a gas type that uses the pressure that gas evaporates and expands, or pressurizes and traps air in a specific space and uses the pressure to eject it to fire a simulated bullet through a cylinder.

Here, we will look at gas-type simulated firearms, and in particular, we will look at the pressure vessel device for gas storage and the relationship between the operation of compressed gas.

First, the configuration and operational relationship of the gas-type simulated gun 10 according to the prior art will be examined with reference to Figure 1 attached.

As shown in FIG. 1, the mock gun 10 according to the prior art has a barrel 12 with a pipe-shaped firing passage for the simulated bullet (BB) at the top, and the pipe-shaped longitudinal direction arranged in the front-back direction. ) is provided.

At the rear of the above-mentioned barrel 12, a magazine chamber 14 is disposed in the shape of a pipe extending in the longitudinal direction of the barrel 12 and temporarily fixes the simulated bullet BB.

In addition, the simulated firearm 10 has a grip portion 16 on the rear lower side that allows the user to hold it with his hand, and the grip portion 16 has an opening formed on the inside to the lower side, and the pressure container device 50, which will be described later, is released through the opening. ) is formed to form a mounting portion 18 that allows insertion of the device.

In addition, the mock gun 10 has a trigger 20 installed in the front upper part of the grip portion 16 and below the barrel 12 described above.

Here, the trigger 20 can be pressed backward by the user's finger pinching motion, and operates to elastically restore the set position under the influence of a normal elastic member in response to the release of the finger force.

And the trigger 20 is connected to the movable bar 22 at the rear.

This movable bar 22 is arranged in the front-back direction, the front end is connected to the trigger 20, and the continuous middle part extends to the inside of the grip part 16 to form the side of the pressure vessel device 50, which will be described later. It is connected to the rear of the pressure vessel device 50 at the corresponding position in a shape that surrounds the position, and the continuous rear end portion contacts or connects with one end of the ratchet 24 installed in the grip portion 16 to move the trigger 20 backward. It functions to transmit force so that the ratchet 24, which receives elastic action, rotates.

The ratchet 24 described above rotates around the first hinge h1 arranged in the left and right directions of the simulated gun 10, and the other end of the ratchet 24 rotates around the first hinge h1. Depending on the position, the hammer 26, which rotates elastically around the second hinge h2 at a position spaced apart from the first hinge h1, is latched or released in response to the formed portion of the ratchet wheel 26a. there is.

Here, the rotation of the hammer 26 described above is counterclockwise from the ready position shown in FIG. 1 around the second hinge h2 from the third elastic portion 28 installed inside the grip portion 16. It receives an elastic force to rotate, and at the same time, the ratchet wheel (26a) forming part of the hammer (26) receives support from the other end of the ratchet (24) and starts in a state where rotation is stopped.

In this state, the hammer 26 is released from the lock on the ratchet wheel 26a due to the operation of the trigger 20 and the movable bar 22 and the rotation of the ratchet 24 therefrom, and the third elastic part ( It rotates counterclockwise from the ready position due to the elastic force of 28).

A slider 30 is installed on the upper part of the above-described mock gun 10, which is arranged in the longitudinal direction of the barrel 12 and slides between limited positions in the front-back direction according to the design.

This slider 30 is generally placed at the front setting position by receiving the elastic action of the first elastic part 32 from the setting part of the simulation gun 10, and is mounted in the mounting part 18 inside the slider 30. It is provided with a cylinder (34) to accommodate the compressed gas ejected from the pressure vessel device (50).

In addition, the cylinder 34 forms a gas inlet 34a that is close to and faces the gas discharge port 58a of the pressure vessel device 50 when the slider 30 is placed in the set position, and this gas inlet 34a ) The interior of the cylinder 34 connected to the cylinder 34 and the percussion chamber 34b, which guides the compressed gas flowing in through the gas inlet 34a toward the ammunition chamber 14 based on the partition wall 34d. It defines a recoil chamber (34c) that guides the piston (36) located at the rear to push it rearward.

And the above-mentioned piston 36 is connected to the cylinder 30 and the second elastic part 38, and is placed in a position to reduce the internal volume of the recoil chamber 34c by receiving the tension of the second elastic part 38. , and the expansion pressure within the recoil chamber 34c acts to form a sliding relationship with the slider 30 toward the rear of the cylinder 30.

In addition, the slider 30 described above has a push block 40 installed on the rear lower side, and the rear end of the push block 40 collides with the hammer 26 that rotates counterclockwise and moves elastically forward. Then, the space between the accumulating pressure chamber 56 and the gas passage 58 is opened by pressing the discharge valve 60 of the pressure vessel device 50, which will be described later, and then, when the slider 30 moves backward or by elastic action, it returns to the restored position. It is in a relationship of moving backwards.

At this time, the restoration movement of the push block 40 and the restoration movement of the above-described discharge valve 60 are performed simultaneously.

Looking at the movement process of the slider 30 from the above configuration, as described above, the backward movement of the trigger 20 and the resulting operation of the hammer 26 cause instantaneous compressed gas from the pressure vessel device 50 to the gas outlet ( It is discharged through 58a).

The compressed gas discharged in this way proceeds into the cylinder 34 through the oppositely located gas inlet 34a, and some of the compressed gas flowing into the cylinder 30 moves to the percussion chamber 34b and enters the ammunition chamber 14. The simulated bullet (BB) on the top is triggered, and the rest moves to the recoil chamber (34c).

The compressed gas flowing into the recoil chamber 34c in this way acts as an expansion pressure that pushes the piston 36, a heavy body, backward, using the cylinder 34 as a support base.

The resulting rearward movement of the piston 36 leads the cylinder 34 and the slider 30 connected by the second elastic portion 38 to the rear, and at this time, the gas inlet 34a of the cylinder 34 releases the above-mentioned gas. At the same time as it leaves the opposing position of the discharge port 58a, the compressed gas in the recoil chamber 34c is released.

In addition, in the above process, the push block 40 pushes the hammer 26 and rotates it to the ready position, and then the ratchet wheel 26a is caught by the ratchet 24, causing the hammer 26 to be in the ready position. Make sure it is in

Afterwards, the slider 30 including the cylinder 34 and the piston 36 moves to the front set position by the elastic action of the first elastic part 32, and during this restoration process, the slider 30 waiting at the top of the magazine part 54 One subsequent simulated bullet (BB) is moved to the ammunition chamber (14) and reloaded.

Subsequently, when the slider 30 is restored to its position, the gas inlet 34a of the above-described cylinder 34 is positioned to face the gas outlet 58a.

Meanwhile, the pressure vessel device 50 according to the prior art, as shown in FIG. 1, includes a magazine unit for sequentially supplying simulated bullets (BB) to a portion of the interior of the main body 52 of the pressure vessel device 50. (54) is formed, and in the remaining part, an accumulating pressure chamber (56) is formed to accommodate liquid compressed gas.

The liquid compressed gas accumulates in the lower part of the above-mentioned pressure accumulation chamber 56, and the upper part of the pressure accumulation chamber 56 traps the vaporized compressed gas.

In addition, a gas passage 58 is formed on the upper side of the pressure accumulation chamber 56 of the main body 52 to guide the movement of compressed gas, and between the pressure accumulation chamber 56 and the gas passage 58 is shown in FIGS. 1 and 2. As shown, a discharge valve 60 is installed to control the movement of compressed gas, and on one side of the pressure accumulation chamber 56, a liquid compressed gas can be injected into the pressure accumulation chamber 56. Installation of one charging valve 62 is performed.

As previously revealed, the pressure vessel device 50 formed in this way is mounted through the opening of the mounting part 18 provided in the grip part 16, so that the gas discharge port 58a, which is the upper part of the gas passage 58, is opened. The center of the gas inlet 34a of the cylinder 34 described above is generally aligned with the gas inlet 34a.

Among the conventional technical configurations examined above, the operation of the piston 36 with respect to the cylinder 34 described above provides the realistic feeling of percussion recoil like an actual firearm using live ammunition through training systems such as video shooting simulators, VR shooting simulators, and the Miles system. It is intended to be implemented from simulated firearms used in.

However, the recoil action of the cylinder 34, piston 36, and slider 30 according to the prior art configuration was significantly insufficient when compared to an actual firearm.

In addition, the second elastic portion 38 that connects the cylinder 34 and the piston 36 is located away from the center of the cylinder 34 and the piston 36, so it moves during the sliding movement of the piston 36. Due to the elastic action of the second elastic portion 38, it moves in the direction of its action, and as a result, there is an unnatural problem in the sliding movement, including uneven wear, between the cylinder 34 and the piston 36.
