Description

[Technical Field]

[0001] The present invention relates to a toy gun, and more particularly to a toy gun that fires BB bullets by discharging gas stored in a gas cylinder through a release valve. [Background technology]

[0002] Toy guns (gas guns) that use compressed gas to fire BB bullets, such as 6 mm diameter BB bullets, have traditionally used alternative chlorofluorocarbons as their power source, but recently carbon dioxide (CO2) gas has also been used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3222458 Summary of the Invention [Problem to be solved by the invention]

[0004] The energy value of a toy gun must be within the range stipulated by laws and regulations such as the Swords and Firearms Control Law. When gas is used as the energy source for firing bullets, the energy value must be kept within the specified range by adjusting the gas flow rate. In addition, wasteful gas release results in poor cost performance, so it is necessary to prevent unnecessary gas release.

[0005] 12 to 16 are front cross-sectional views of a gas cylinder storage section 102 provided in a valve body 111 located above a grip 106 of a conventional toy gun, and a release valve 103 provided adjacent to the gas cylinder storage section 102, showing a state in which a gas cylinder 101 is stored in the gas cylinder storage section 102. The release valve 103 is shown in a state before being opened. The valve body 111 is a sealed component. As shown in FIG. 15, the valve body 111 is provided with a release valve storage section 124 in the form of a through hole extending from the muzzle side (left side in the figure) to the opposite side of the muzzle (right side in the figure). The release valve 103 is housed inside the hollow release valve storage section 124.

[0006] The discharge valve 103 has a valve pin 122 and a base 123 . A cylindrical hollow base portion 121 is provided in the base portion 123 from the muzzle direction to the direction opposite the muzzle (horizontal direction in the figure). The fitting portion 1035 of the valve pin 122 is inserted into the hollow base portion 121 of the base portion 123 in the muzzle direction (horizontal direction in Figure 15). The fitting portion 1035 of the valve pin 122 is slidable within the hollow base portion 121, and the base portion 123 allows the valve pin 122 to slide freely from the muzzle direction to the direction opposite the muzzle (horizontal direction in Figure 15). The base portion 123 supports the valve pin 122 in the release valve storage portion 124.

[0007] The valve pin 122 of the discharge valve 103 has a hollow portion 1031 inside that is open to the muzzle side (left side in the drawing) and the side (upward in the drawing), and an outer peripheral portion 1032 that is cylindrically provided around the hollow portion 1031. The fitting portion 1035 does not have a hollow portion 1031. The outer circumferential portion 1032 is made up of a small diameter portion 1032b and a large diameter portion 1032a having a larger diameter than the small diameter portion 1032b.

[0008] The release valve 103 has a valve spring 107 attached around the small diameter portion 1032b of the outer circumferential portion 1032. The valve pin 122 of the release valve 103 is always biased in the direction away from the muzzle by the valve spring 107, and is able to slide toward the muzzle and in the direction opposite to the muzzle. As shown in Figures 12 to 16, the release valve 103 is always biased in the direction opposite to the arrow in Figure 15 by the biasing force of the valve spring 107, pushing it in the closing direction. The outer peripheral portion 1032 has an end portion opposite the muzzle that has a larger diameter portion 1032a than the muzzle side, and the tip opposite the muzzle has a contact portion 122a that comes into contact with the base portion 123.

[0009] The end of the valve pin 122 of the release valve 103 opposite the muzzle (the right side in Figure 15) maintains the same outer diameter as shown in Figure 16, but has a hollowed-out recess 1034 on the inside, and is provided with a pointed, protruding contact portion 122a to improve contact with the base 123 and maintain airtightness. As shown in FIG. 13, the tip of the discharge valve 103 located at the tip portion on the muzzle side of the discharge valve is not exposed from the discharge valve housing 124 to the muzzle side gas passage 109 when the discharge valve 103 is closed.

[0010] When gas is supplied from the gas cylinder 101 to the release valve 103, the gas cylinder 101 is pushed into the gas cylinder storage section 102, the storage section presser 108 presses the bottom of the gas cylinder 101, the gas cylinder 101 is pierced into the needle 104 provided in the valve body 111, opening the gas cylinder 101, and gas is supplied into the valve body 111 through the passage 105 provided inside the needle 104. When the trigger (not shown) is pulled, the hammer (not shown) strikes the valve pin 122 hard, overcoming the biasing force of the valve spring 107 and moving the valve pin 122 in the muzzle direction as indicated by the arrow in FIG. 15. Then, the contact portion 122a, which had been in contact with the base 123, separates from the base 123, and a side opening (not shown) of the hollow portion 1031 provided in the valve pin 122 is exposed inside the release valve storage section 124. This allows the CO2 gas that filled the gap between the release valve storage section and the release valve to enter the side opening, and the CO2 gas is released from the hollow section 1031 toward the muzzle, and the BB bullet is fired through the muzzle-side gas passage 109.

[0011] In conventional toy guns, the CO2 gas pressure is so high that when the release valve is opened, more CO2 gas than necessary is released through the gas passage inside the release valve and out of the gun. This type of release valve makes it difficult to maintain an appropriate gas flow rate. Another issue is the waste of CO2 gas. [Means for solving the problem]

[0024] A first embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes the grip of a toy gun (air gun). The embodiment of the present invention is a handgun-type air gun. In such handgun-type air guns, the gas cylinder is often stored in the grip, and the valve body is often located near the grip because it receives gas from the gas cylinder. However, the present invention can also be used with rifle-type and shotgun-type air guns. Because the gun body, including the barrel, is large, the mechanism according to the present invention may be housed in a location other than the grip. Therefore, the location of the mechanism according to the present invention may vary depending on the gun and is not limited to the grip. Both the gas cylinder and the valve body may be located in a location other than the grip. 1 is a front cross-sectional view of a valve body 11 located above a grip 1 of a toy gun according to an embodiment of the present invention and a gas cylinder storage section 12 provided inside the grip 1, with a gas cylinder 13 stored in the gas cylinder storage section 12. The release valve 21 is shown in a state before being opened. When the release valve 21 is opened, CO2 gas supplied from the gas cylinder 13 is supplied to the muzzle side, causing a BB bullet to be fired. When the release valve 21 is closed, the supply of CO2 gas to the muzzle side is stopped.

[0025] Reference numeral 11 denotes a valve body. The valve body 11 is a sealed component, and in this embodiment, is provided above the grip 1 of the toy gun. However, like the gas cylinder, the location of the valve body 11 may vary depending on the gun. The valve body 11 may also be provided so as to be detachable from the gun body. As shown in Figures 1 and 2, the valve body 11 is provided with a discharge valve storage section 18. The discharge valve storage section 18 is provided inside the valve body 11 in the form of a hollow through-hole extending from the muzzle side (left side in the drawing) to the opposite side of the muzzle (right side in the drawing). A release valve 21 is housed inside the hollow release valve housing 18. A release valve housing packing 28 is provided on the muzzle side of the release valve housing 18.

[0026] The discharge valve 21 has a substantially cylindrical shape and includes a valve pin 22 and a base 23. A hollow cylindrical base hollow portion 231 is provided in the direction opposite to the muzzle (horizontal direction in the drawing) from the muzzle direction of the base 23. The fitting portion 221, which is the end of the valve pin 22 opposite to the muzzle side, is inserted into the base hollow portion 231. Base 23 allows valve pin 22 to slide and supports valve pin 22 in release valve housing 18. Valve pin 22 is slidable. The tip of valve pin 22 on the muzzle side is inserted into release valve housing packing 28, which always maintains an airtight seal.

[0027] The valve pin 22 of the discharge valve 21 has a hollow portion 24 inside that is open to the muzzle side (left side in the drawing) and the side (upper side in the drawing), and an outer peripheral portion 25 that is cylindrically formed around the hollow portion 24. The fitting portion 221 does not have a hollow portion 24. The hollow portion 24 is hollow, with a muzzle-side opening 241 inside the valve pin 22. A side opening 242 of the hollow portion 24, which is provided in the outer periphery 25 of the valve pin 22, is provided so that the end of the hollow portion 24 appears on the side opposite the muzzle. The side opening 242 is provided inside the tip of the outer periphery 25 that contacts the base 23. Therefore, when the valve is in the closed state, the side opening 242 is not exposed inside the release valve housing 18. Although the hollow portion 24 appears to pass through the center of the valve pin 22 in the drawings including FIG. 3, it may pass through a location offset from the center. The valve pin 22 is constantly biased by the biasing force of the valve spring 17 in the direction opposite to the muzzle on the right side in FIGS. 1 to 4, and is pushed in the closing direction. Reference numeral 251 denotes a valve pin tip portion. Valve pin tip portion 251 is provided closer to the muzzle (left side in FIGS. 2 and 4) than large diameter portion 25a of outer circumferential portion 25. Valve pin tip portion 251 has an open tip. The muzzle-side opening 241 is a hollow portion of the valve pin tip 251 . Reference numeral 242 denotes a side opening of the valve pin 22. The side opening 242 is provided so as to open to the outer periphery 25 on the inner side of the contact portion 26 arranged at the tip of the outer periphery 25 that contacts the base portion 23.

[0028] 10, a represents the difference in outer circumference between outer periphery 25 and valve pin tip 251. The outer circumference of valve pin tip 251 is set smaller than the outer circumference of outer periphery 25 by the difference a. The diameter of the valve pin tip 251 located at the tip of the valve pin 22 on the muzzle side is made smaller than the diameter of the valve pin 22 stored in the discharge valve storage section 18, specifically the small diameter section 25b of the outer periphery 25. Regarding the difference a between the outer circumference of outer periphery 25 and valve pin tip 251, in the embodiment, the distance from the outer circumference of the valve pin tip to the center of valve pin 22 is approximately 86% of the distance from the outer circumference of small diameter portion 25b of outer periphery 25 to the center of valve pin 22.

[0029] As shown in FIG. 2, CO 2 gas from the gas cylinder 13 is filled into the gap S between the release valve 21 and the release valve housing 18. Next, when the trigger (not shown) is pulled, the hammer (not shown) strikes the valve pin 22 hard, overcoming the biasing force of the valve spring 17 and moving the valve pin 22 toward the muzzle as indicated by the arrow in Figures 3 and 4. This causes the valve pin contact portion 26, which had been in contact with the base 23, to separate from the base 23, exposing the side opening 242 of the hollow portion 24 in the valve pin 22 to the inside of the release valve housing 18. This causes the CO2 gas that had filled the gap S to enter the side opening 242 and is released from the hollow portion 24 toward the muzzle, firing a BB bullet.

[0030] The outer peripheral portion 25 is made up of a small diameter portion 25b and a large diameter portion 25a having a larger diameter than the small diameter portion 25b. Valve pin 22 has valve spring 17 attached around small diameter portion 25b of outer periphery 25. As shown in Figures 1 and 2, valve pin 22 of release valve 21 is always biased by valve spring 17 in the direction away from the muzzle (to the right in the figures), and is able to slide toward the muzzle (to the left in the figures) and in the direction opposite to the muzzle. At the end of the outer circumferential portion 25 opposite the muzzle, a large diameter portion 25a is provided with a larger diameter than the muzzle side, and the tip of the large diameter portion 25a opposite the muzzle has a contact portion 26 that comes into contact with the base portion 23.

[0031] The contact portion 26 at the end of the valve pin 22 of the release valve 21 opposite the muzzle (the right side in Figures 1 to 4) maintains the same outer diameter as shown in Figures 2 and 3, but has a hollowed-out recess 27 on the inside. The contact portion 26 has a pointed tip to improve contact with the base portion 23 and maintain airtightness, and is formed in a sharp, protruding shape.

[0032] As illustrated in Figure 10, b is the length of the valve pin tip 251; The symbol c denotes the length from the rear end of the valve pin tip 251 of the outer circumferential portion 25 to the tip of the large diameter portion 25a on the muzzle side. In this embodiment, the length relationship is approximately b=1 and c=3.

[0033] A gas cylinder storage section 12 is provided inside the lower part of the valve body 11, that is, inside the lower part of the grip section 1. A gas cylinder 13 is stored in the gas cylinder storage section 12. The gas cylinder storage section 12 and the gas cylinder 13 may be provided separately from the toy gun. An insertion port 15 is provided at one end of the gas cylinder storage section 12.

[0034] Reference numeral 30 denotes a needle. The needle 30 has a needle-shaped tip. The needle 30 is installed in the innermost part of the gas cylinder storage section 12 where the gas cylinder 13 is stored, with the needle tip facing the insertion port 15 of the stored gas cylinder 13. The gas cylinder 13 is inserted into the gas cylinder storage section 12 through the insertion port 15 and pushed in with the insertion port holder 16, whereby the needle 30, which is installed in the innermost part of the gas cylinder storage section 12 facing the storage port of the gas cylinder 13, pierces the gas cylinder 13, opening it, and allows gas to flow into the valve body. A ready-made product is used as the needle 30.

[0035] A gas passage 14 is provided between the valve body 11 and the gas cylinder 13.

[0036] A muzzle-side gas passage 31 is provided continuous with the muzzle side of the release valve housing 18 (on the left side in the drawing). Reference numeral 32 denotes a passage bend. The passage bend 32 is the junction between the release valve housing 18 and the muzzle-side gas passage 31 provided from the release valve housing 18 toward the muzzle, and is bent at approximately right angles to the sliding direction of the valve pin 22 toward the muzzle and the opposite side from the muzzle, ensuring space for sliding of the valve pin 22. In this embodiment, another passage bend is provided above this passage bend 32, allowing gas to flow toward the muzzle.

[0037] 4 to 8, a protrusion 34 is provided on the bending surface of the passage bending portion 32, i.e., on the valve pin facing surface 33 of the valve pin 22, which faces the position where the valve pin 22 of the release valve 21 slides toward the muzzle. The protrusion 34 acts as a stopper or chock when the valve pin 22 moves toward the muzzle. The valve pin tip 251 abuts against the protrusion 34, creating a gap between the valve pin tip 251 and the valve pin facing surface 33. This gap becomes a gas flow path when the valve pin 22 advances and gas flows out toward the muzzle.

[0038] A valve pin tip 251 located at the tip of the valve pin 22 on the muzzle side is exposed from the discharge valve housing 18 and protrudes into the muzzle side gas passage 31. The diameter of the discharge valve storage section 18 is made larger than the valve pin tip 251 located at the tip of the discharge valve on the muzzle side. The muzzle side of the valve pin 22 is extended, and the extended muzzle side portion, i.e., the valve pin tip portion 251, has an even smaller diameter than the side opposite the muzzle, i.e., the small diameter portion 25b of the valve pin 22.

[0039] The pre-opening, opening and closing of the discharge valve 21 will now be described. 1 to 4, the valve pin 22 is constantly biased in the closing direction away from the muzzle (right side in Figures 1 to 4) by the biasing force of the valve spring 17. Therefore, the release valve 21 is closed and in the pre-open state. From the moment the gas cylinder 13 is stored in the gas cylinder storage section 12, CO2 gas flows into the valve body 11 via the gas passage 14, and the gap S between the release valve 21 and the release valve storage section 18 is filled with CO2 gas.

[0040] When the trigger (not shown) is pulled, the hammer (not shown) strikes the valve pin 22 hard, overcoming the biasing force of the valve spring 17 and moving the valve pin 22 toward the muzzle. As a result, the contact portion 26 that had been in contact with the base 23 separates from the base 23, and the side opening 242 of the hollow portion 24 provided in the outer periphery 25 of the valve pin 22 becomes exposed inside the release valve housing 18. This allows the CO2 gas that had filled the gap S to enter the side opening 242.

[0041] The valve pin 22 moves toward the muzzle, and the valve pin tip 251 comes into contact with the protrusion 34 provided on the valve pin facing surface 33 and stops. CO2 gas that enters side opening 242 of valve pin 22 passes through hollow portion 24 and, while valve pin tip 251 is in contact with protrusion 34, is ejected toward valve pin opposing side 33, and then flows out into muzzle-side gas passage 31. The CO2 gas that flows into the muzzle-side gas passage passes through the gap created by the contact between valve pin tip 251 and protrusion 34 and the gap between valve pin tip 251 and the muzzle-side gas passage 31, and is ejected toward a BB bullet located closer to the muzzle than muzzle-side gas passage 31, and is pushed by gas pressure to fire the BB bullet. Thereafter, the valve pin 22 moves away from the muzzle due to the biasing force of the valve spring 17, and the discharge valve 21 closes.

[0042] In the toy gun according to this embodiment, by providing a narrow section in the flow path while ensuring a flow path for CO2 gas, the flow rate of CO2 gas used can be adjusted appropriately, the energy value can be kept within a predetermined range, and waste of the gas used can be reduced.

[0043] A second embodiment shown in FIG. 11 will now be described. In the second embodiment, the muzzle side of the valve pin 22 is extended, and a gap is provided between the valve pin tip 251, which is the tip of the extended muzzle side, and the inner diameter and inner surface of the discharge valve housing 18. Therefore, in the second embodiment as well, by providing a narrow portion midway through the flow path while still ensuring the flow path, the flow rate of the gas can be set to an appropriate value.
