Description

Toy gun and installation equipment

The present invention relates to a toy gun that can be used to mount a gas cylinder and that uses the pressure generated by the compressed gas in the gas cylinder to emit a pellet, and an installation tool for mounting a gas cylinder in the toy gun.

In the past, a toy gun that can mount a gas cylinder and use a pressure generated by a compressed gas in the gas cylinder to emit a projectile is quite popular. An example of this is the toy gun described in Japanese Laid-Open Patent Publication No. Hei 7-41292.

According to the Japanese Patent Publication No. 7-41292, the toy gun is provided with a cylinder 22 (cylinder). The compressed carbon dioxide gas is stored in the cylinder 22, and the gas chamber 24 of the toy gun is filled with carbon dioxide gas. The user of the toy gun pulls the upper jaw 34 back so that the piston 51 is behind, and then advances the upper jaw 34 to return to its original position. In this state, if the user pulls the trigger 61, the piston 51 advances. If the piston 51 advances, the air in the cylinder 44 is released into the barrel 15, causing the projectile 12 in the barrel 15 to be ejected from the muzzle 16. Further, when the piston 51 advances, the hammer 31 advances to pull the valve 26, and the barrier of the air chamber 24 and the hammer storage chamber 25 by the valve 26 is broken. As a result, the gas in the gas chamber 24 is released into the hammer storage chamber 25, and the hammer 31 is pushed backward to retract the upper jaw 34, so that the piston 51 is positioned rearward. Thereafter, the upper jaw 34 automatically advances and retracts each time the trigger 61 is pulled.

In the toy gun described in Japanese Laid-Open Patent Publication No. Hei 7-41292, the upper jaw 34 can be automatically advanced and retracted, and a plurality of projectiles can be fired in a short time like a real gun. Therefore, the toy gun described in Japanese Laid-Open Patent Publication No. Hei 7-41292 must consume a large amount of compressed gas.

Here, in order to use the toy gun for a long period of time without replacing the cylinder 22, it is conceivable to increase the size of the cylinder 22. However, in this case, it is difficult to carry the cylinder 22.

The object of the present invention is to allow a toy gun that uses a compressed gas to emit a projectile to be used for a long period of time without changing the gas cylinder, and to enhance the portability of the gas cylinder.

The toy gun of the present invention includes: a projectile holding portion for holding a projectile, a gas chamber casing for forming a gas chamber, and a gas discharge portion for guiding the compressed gas in the gas chamber to the projectile held by the projectile holding portion, a valve for opening and closing the communication between the gas chamber and the gas discharge portion, an operation portion for opening and closing the valve, and a plurality of cylinder mounting portions for mounting a gas cylinder for supplying compressed gas, and each of the foregoing The first valve portion of the cylinder mounting portion and the gas cylinder attached from the cylinder mounting portion guide the compressed gas to the gas introduction portion in the gas chamber.

The mounting tool according to the present invention includes: a plurality of cylinder mounting portions for mounting a gas cylinder for supplying compressed gas; and a unit mounting portion detachably attachable to a mounting portion of the toy gun to be used for The compressed gas supplied from the gas cylinder installed in the cylinder mounting portion is guided to the toy gun; the first valve portion is disposed in each of the cylinder mounting portions; and the second valve The portion is provided in the unit mounting portion.

In another aspect, the mounting tool of the present invention includes: a gas chamber casing detachably formed with respect to a toy gun having a projectile holding portion for holding a projectile, and is used to form a gas chamber; and a valve for discharging the gas portion Opening and closing with the air chamber; the gas discharge portion is provided in the toy gun for guiding the compressed gas in the air chamber to the projectile held by the projectile holding portion; and a plurality of cylinder mounting portions for mounting a gas cylinder for supplying compressed gas; a first valve portion provided in each of the cylinder mounting portions; and a gas introduction portion for guiding the compressed gas from the gas cylinder attached to the cylinder mounting portion to the gas chamber.

A plurality of cylinders can be installed in accordance with the present invention. Further, the cylinder mounting portion can be closed by the first valve portion. Therefore, the toy gun can use a plurality of small gas cylinders without using a large gas cylinder. Therefore, a toy gun that uses a compressed gas to fire a projectile can be used for a long time without replacing the gas cylinder. Furthermore, the portability of the cylinder can be improved. Moreover, the cylinder can be miniaturized, and the elastic design of the toy gun can be sought.

An embodiment will be described based on Figs. 1 to 13 . This embodiment is referred to as a first embodiment for convenience of explanation. Figure 1 is a left side view of the toy gun 101. A gas cylinder 102 (cylinder) is installed in the toy gun 101. When the user uses the toy gun 101, the handle 104 is grasped by hand, the trigger 105 is held by a finger, and the muzzle 103 is directed toward the object to be fired (for example, the target), and the trigger 105 is pulled. When the trigger 105 is pulled, borrow The projectile B is emitted from the muzzle 103 by the pressure of the compressed gas enclosed in the gas cylinder 102. Hereinafter, the side of the muzzle 103 is referred to as the front side of the toy gun 101. Further, the side of the grip 104 is referred to as the rear side of the toy gun 101.

Fig. 2 is a left sectional view showing the internal structure of the toy gun 101. In Fig. 2, the portion filled with compressed gas is filled with dots. The toy gun 101 includes a gun skeleton 111, a magazine 112, a barrel 113, a bolt 121, a chamber casing 122, a valve 123, a bolt spring 124, and a valve spring 129. The gun skeleton 111 is a part constituting the gun body for defining the front-rear direction of the toy gun 101.

The magazine 112 extends downward from a projectile introduction port 190a (described later) provided in the air chamber casing 122. The magazine 112 is formed in a tubular shape in which only one end portion is opened, and the closed end is located below and can be attached to and detached from the gun skeleton 111. A magazine spring 112a and a magazine follower 112b are disposed in the magazine 112. The magazine spring 112a connects the closed end of the magazine 112 to the magazine follower 112b. The projectile B is housed in the magazine 112. The projectile B in the magazine 112 is pushed up by the magazine spring 112a, and is fed into the passage 190 (described later) from the projectile introduction port 190a.

The barrel 113 extends in the front-rear direction of the gun body and protrudes from the gun skeleton 111 toward the front of the toy gun 101. The front end of the barrel 113 becomes a muzzle 103. The rear end of the barrel 113 is coupled to the front side of the gun frame 111. The barrel 113 may be housed inside the gun frame 111.

The gas chamber casing 122 is housed in the gun skeleton 111. A passage 190 is formed in the plenum housing 122. The passage 190 linearly extends from the rear end portion 103a of the barrel 113 opposite to the muzzle 103 in the front-rear direction of the gun body, and communicates with the air chamber 126 (described later). The projectile B supplied from the magazine 112 to the projectile introduction port 190a is pushed up by the magazine follower 112b, is located in the passage 190, and is held by the projectile holding portion 192. An example of the projectile holding portion 192 is a minute recess formed in the upper surface of the space in the passage 190.

An air chamber 126 is formed inside the plenum housing 122. The aforementioned passage 190 extends to the front side of the air chamber 126. The rear side of the air chamber 126 is closed by the rear cover 122a. A through hole 122b penetrating the front-rear direction of the gun body is formed in the rear cover 122a. An annular seal 122c is attached to the front end surface of the rear cover 122a and around the through hole 122b. On the rear side of the through hole 122b, the inner diameter is increased to become the fitting hole 122d. The abutting portion 121e (described later) provided in the bolt 121 is fitted into the fitting hole 122d.

A gas introduction path 122e is formed in the gas chamber casing 122. The gas chamber casing 122 has a shape protruding downward, and is inserted into the gun skeleton 111 to form a gas introduction path 122e.

The bolt 121 is housed in the gun skeleton 111. The bolt 121 has a cylindrical shape and extends toward the front and rear direction of the gun body. The front side of the bolt 121 is an open end 121a. The rear side of the bolt 121 is a closed end 121b. The gun 121c protrudes upward from the upper surface of the bolt 121. A part of the gun 121c protrudes upward from the gun skeleton 111. The locking projection 121d protrudes downward from the lower side of the rear side of the bolt 121. The abutting portion 121e protrudes from the closed end 121b toward the inner space of the bolt 121.

The bolt 121 is movable freely in the front-rear direction of the gun body. The bolt 121 starts to advance when the user pulls the trigger 105, and reciprocates between the pressing position 121A and the retracted position 121B by the bolt spring 124 and the pressure of the compressed gas. Here, the retracted position 121B is a position at which the abutting portion 121e is separated from the bolt 121 of the sliding projection 123b (described later) of the valve 123 on the rear side of the toy gun 101. Fig. 2 shows the case where the bolt 121 is located at the retreat position 121B. Further, the pressing position 121A means that the abutting portion 121e contacts the position of the bolt 121 of the sliding projection 123b of the valve 123 at the front side of the toy gun 101 from the retracted position 121B. Fig. 3 shows the case where the bolt 121 is located at the pressing position 121A.

The bolt spring 124 is located between the outer side surface of the closed end 121b of the bolt 121 and the rear inner side surface 111b of the gun frame 111. The bolt spring 124 pushes the bolt 121 located at the retracted position 121B toward the pressing position 121A.

The valve 123 is disposed between the gas chamber 126 and the passage 190 and disposed inside the gas chamber 126. A flange portion 123a and a sliding protrusion 123b are formed on the rear end side of the valve 123. The flange portion 123a protrudes from the outer circumference of the valve 123 in the radial direction. The sliding projection 123b is fitted into the through hole 122b and protrudes toward the fitting hole 122d. The valve 123 is formed as a straight line 123c and an inclined path 123d. The straight line 123c is connected to the inclined path 123d to allow the compressed gas to pass therethrough. The straight line 123c has an opening formed in the front end surface of the valve 123 and extends in the front-rear direction of the gun body. The inclined path 123d extends in a direction inclined with respect to the straight line 123c, and an opening is formed between the flange portion 123a and the sliding protrusion 123b. An O-ring 127 and a washer 128 are attached to the outer periphery of the front end side of the valve 123. The O-ring 127 is sandwiched by the gasket 128 and the inner wall of the plenum housing 122.

The valve spring 129 is disposed between the washer 128 and the flange portion 123a and is disposed to wrap around the outer circumference of the valve 123. The valve spring 129 pushes the washer 128 forward to press the O-ring 127 against the inner wall of the plenum housing 122. Further, the flange portion 123a is pressed against the seal member 122c by the valve spring 129. Thereby, the communication between the passage 190 and the air chamber 126 is closed.

Fig. 3 is a left sectional view showing the internal structure of the toy gun 101 in a state in which the bolt 121 is in the pressing position 121A. When the bolt 121 advances and reaches the pressing position 121A, the outer peripheral portion of the rear side of the air chamber casing 122 is fitted to the open end 121a of the bolt 121 (see FIG. 2). When the bolt 121 is further advanced, the abutting portion 121e pushes the sliding projection 123b of the valve 123 projecting in the fitting hole 122d forward. Thereby, the valve 123 is slidably moved to the front side, and the flange portion 123a is separated from the seal 122c, and the communication between the passage 190 and the air chamber 126 is opened.

When the communication between the passage 190 and the gas chamber 126 is opened, the compressed gas filled in the gas chamber 126 flows into the passage 190 through the inclined passage 123d and the straight line 123c as indicated by the arrow in Fig. 3, and the shot holding portion is held. The projectile B (see Fig. 2) held by 192 is pressed behind. As a result, the projectile B is caused to fly out from the muzzle 103 (see Fig. 2). Here, the inclined path 123d, the straight line 123c, and the passage 190 are gas discharge portions 194 that constitute the projectile B that guides the compressed gas in the gas chamber 126 to the projectile holding portion 192. Further, the valve 123 opens and closes the communication between the gas chamber 126 and the gas discharge portion 194.

Further, when the communication between the passage 190 and the air chamber 126 is opened, the compressed gas enters the gap S between the inner wall surface of the through hole 122b and the sliding projection 123b as indicated by the arrow in Fig. 3 . This compressed gas pushes the abutting portion 121e backward through the through hole 122b. Thereby, the bolt 121 starts to retreat and reaches the retreat position 121B (refer to FIG. 2). The bolt 121 reaching the retreat position 121B is pushed by the bolt spring 124 to advance again. Next, when the bolt 121 reaches the pressing position 121A, the sliding protrusion 123b of the valve 123 is pushed forward. In this manner, the bolt 121 is repeatedly advanced and retracted to reciprocate. Further, the bolt 121 abuts and leaves the valve 123 during one reciprocation, and opens and closes the passage 190 in communication with the air chamber 126.

When the abutting portion 121e leaves the sliding projection 123b, the valve spring 129 pushes the valve 123 back. Thereby, the valve 123 is slid back and the flange portion 123a is brought into close contact with the seal 122c. As a result, the passage 190 is connected to the gas chamber 126 to be closed. Then, the inside of the gas chamber 126 is filled with the compressed gas supplied from the gas introduction path 122e.

Refer to Figure 2 again. The toy gun 101 includes a trigger 105, a trigger spring 131, a bolt stopper 132, and a bolt stopper iron spring 133. The trigger 105 is located forward of the grip 104 (see Fig. 1). The trigger 105 is rotatably attached to the gun frame 111 around the fulcrum 105a. The trigger 105 has a finger rest portion 105d and a rear extension portion 105b. The finger hanging portion 105d extends downward from the fulcrum 105a. The rear extension portion 105b extends rearward from the fulcrum 105a. The bolt stopper iron pushing portion 105c protrudes upward from the upper surface of the rear extending portion 105b. The trigger spring 131 pushes the finger rest portion 105d in the clockwise direction of the second drawing.

The bolt stopper 132 is disposed between the bolt stopper upper pushing portion 105c and the lower portion of the bolt 121. The bolt stopper 132 is rotatably attached to the gun frame 111 around the shaft core 132a. The bolt stopper 132 includes a flat front projection 132b and a fan-shaped rear projection 132c on the side. The front protruding portion 132b protrudes forward more than the axial core 132a. The rear protruding portion 132c protrudes rearward from the axial core 132a. Above the rear protruding portion 132c, a braking portion 132d for stopping the locking projection 121d of the bolt 121 is provided. The bolt stopper iron spring 133 abuts against the lower surface of the rear protruding portion 132c, and rotates the bolt stopper 132 in the counterclockwise direction of FIG. 2 to raise the braking portion 132d upward. When the braking portion 132d is raised upward, the braking portion 132d catches the locking projection 121d of the bolt 121 and prevents the bolt 121 from advancing.

When the user holds the gun 121c and moves the bolt backward, the locking projection 121d crosses the braking portion 132d. Next, when the user's hand releases the gun 121c, the bolt 121 is pushed by the bolt spring 124 to advance, and the locking projection 121d is caught by the braking portion 132d. Thereafter, when the user pulls the trigger 105 back with a finger, the trigger 105 rotates counterclockwise in FIG. 2 to move the bolt iron pushing-up portion 105c to shift the front protruding portion 132b upward. Thereby, the bolt stopper 132 is rotated in the clockwise direction of FIG. 2, and the locking projection 121d is displaced downward. As a result, the bolt 121 is pushed forward by the bolt spring 124, and the valve 123 is moved forward to open the communication between the air chamber 126 and the gas discharge portion 194. Further, in Fig. 2, the state of the trigger 105, the trigger spring 131, the bolt stopper 132, and the bolt stopper spring 133 when the trigger 105 is pulled backward is indicated by a two-dot chain line.

When the user's finger leaves the trigger 105, the trigger spring 131 pushes the finger-hanging portion 105d in the clockwise direction of FIG. 2, and the bolt stopper iron pushing-up portion 105c is displaced downward. Here, the bolt stopper iron 133 presses the bolt stopper 132 so as to rotate counterclockwise in FIG. Therefore, the front protruding portion 132b moves downward, and the braking portion 132d moves upward. As a result, the advancement of the bolt 121 is prevented, and the valve 123 is pushed backward, and the communication between the air chamber 126 and the gas discharge portion 194 is closed. In this manner, the trigger 105 constitutes an operation portion 130 for opening and closing the valve 123.

Here, the gas cylinder 102 used for the toy gun 101 and the cylinder mounting tool 201 for attaching the gas cylinder 102 to the toy gun 101 will be described. The cylinder mounting device 201 is a "mounting device" equivalent to the scope of the patent application. First, refer to Figure 1. In the present embodiment, the gas cylinder 102 is housed in the cylinder mounting tool 201 and is located in front of the trigger 105. The cylinder mounting tool 201 is attached to the unit mounting portion 122f in a state in which the gas cylinder 102 is housed (see also FIG. 2). The unit to-be-attached portion 122f is an end portion provided below the gas introduction path 122e.

The cylinder mounting tool 201 has a box shape in which the long sides are formed in the vertical direction. The unit mounting portion 202 protrudes from the upper surface of the cylinder mounting tool 201. Inside the cylinder mounting tool 201, a storage space 203 for accommodating the two gas cylinders 102 is formed. A partition portion 203a is provided in the housing space 203. The partition portion 203a is an arrangement space 204a in which the storage space 203 is formed to arrange the respective gas cylinders 102. A gas cylinder introduction port 204 that communicates with the storage space 203 is formed on the side surface of the cylinder mounting tool 201. Two cylinder pressers 206 are disposed in the storage space 203 and in the vicinity of the mounting device bottom 205 on the opposite side of the unit mounting portion 202. The shaft body 207 is respectively extended from the cylinder pressing member 206. Each axle body 207 extends through the bottom 205 of the mounting fixture. The handle 208 is provided at the end of each of the shaft bodies 207 outside the storage space 203. Further, a screw portion 209 is provided on the outer circumference of each of the shaft bodies 207. The threaded portion 209 is screwed to the bottom 205 of the mounting device. If the user rotates the handle 208, the cylinder presser 206 can move up and down. When the user stops rotating the handle 208, the cylinder presser 206 is fixed so as not to fall by the screwing of the mounting device bottom 205 and the threaded portion 209. The cylinder presser 206, the shaft body 207, the handle 208, and the screw portion 209 are the sealing materials for moving the gas cylinder 102 disposed in the arrangement space 204a and piercing the gas cylinder 102 by the needle portion 217a (see Fig. 6 and the like). 102c (refer to Fig. 4, etc.), in which the gas cylinder 102 is fixed.

The technique of fixing the gas cylinder 102 by the needle portion 217a piercing the sealing material 102c of the gas cylinder 102 disposed in the arrangement space 204a can replace the cylinder presser 206, the shaft 207, the handle 208, and the threaded portion 209. The technique described in the specification of U.S. Patent No. 7,290,539 is used. In this case, the panel having the rotating rotor is attached to the cylinder mounting tool 201, and the storage space 203 is opened and closed by the panel. When the panel is closed, the rotating rotor presses the gas cylinder 102 of the storage space 203. When the gas cylinder 102 is pressed by the rotary rotor, the gas cylinder 102 can be fixed in the storage space 203, and the needle portion 217a can pierce the sealing material 102c of the gas cylinder 102.

FIG. 4 is a perspective view of the gas cylinder 102. The gas cylinder 102 has a cylindrical shape. The compressed gas is sealed in a gas cylinder 102. The compressed gas is, for example, carbon dioxide gas, flon gas, or fluorocarbon gas. The first end portion 102a of the gas cylinder 102 is constricted in a conical shape. A gas discharge port 102b is provided at the tip end of the first end portion 102a. The gas discharge port 102b is sealed by the sealing material 102c. The second end portion 102d of the gas cylinder 102 is a closed end.

In the present embodiment, the cylinder mounting portion 210, the first valve portion 211, the unit mounting portion 202, and the second valve portion 212 are unitized to belong to the cylinder mounting tool 201. Therefore, the cylinder mounting tool 201 can be integrally attached and detached with respect to the unit-mounted portion 122f.

The communication path 213 has a main path 213a. The main path 213a is provided in the unit mounting portion 202 and extends inside the unit mounting portion 202. The main road 213a is divided into two divergent roads 213b. The branch road 213b is composed of a first road 213ba and a second road 213bb. The first path 213ba extends from the end of the main path 213a in a direction crossing the main path 213a. The second path 213bb connects the first path 213ba to the arrangement space 204a.

The cylinder mounting portion 210 and the first valve portion 211 are disposed in the branch path 213b. Hereinafter, the cylinder mounting portion 210 and the first valve portion 211 will be described. The cylinder mounting portion 210 has an unsealing member 217 (described later) and is provided at an end portion of the branching passage 213b on the side of the arrangement space 204a. The gas discharge port 102b of the gas cylinder 102 is attached to the cylinder mounting portion 210 (see Fig. 4). The first valve portion 211 is provided in the cylinder mounting portion 210. The first valve portion 211 is used to open and close the communication between the communication passage 213 and the arrangement space 204a. The first valve portion 211 includes a check valve 211a. The check valve 211a is composed of a valve ball 214 and a ball ball seal 215.

In the second passage 213bb, the valve ball 214, the ball ball seal 215, the first auxiliary seal 216, the unsealing member 217, and the second auxiliary seal 218 are sequentially introduced from the arrangement space 204a.

A flange portion 220b is formed on a side surface of the valve body 220 at a portion closer to the branch path 213b than the opening of the vent hole 220a. The valve body spring 219 is located between the flange portion 220b and the spring receiving portion 213d, and presses the valve body 220 toward the opening portion 202a. The spring receiving portion 213d is provided at the boundary between the main path 213a and the branch path 213b, and protrudes toward the inner side of the communication path 213. The valve body seal 221 is formed with a through hole 221a through which the valve body 220 enters. The flange portion 220b of the valve body 220 pressed by the valve body spring 219 is pressed against the valve body seal 221 . The third auxiliary seal 222, the press-fitting member 223, and the nozzle support member 224 are for preventing the movement of the valve body seal 221 toward the opening portion 202a side. Further, the opening of the vent hole 220a located on the side of the valve body 220 is in contact with the inner peripheral surface of the through hole 221a. Thereby, the main path 213a is blocked.

Fig. 7 is a left sectional view showing a communication path 213 in a state in which the unit is mounted by the mounting portion 122f. Refer to Figure 7 and Figure 2. The unit to-be-attached portion 122f has a nozzle 122g (see FIG. 2). The nozzle 122g is in communication with the gas introduction path 122e. The outer periphery of the tip end of the nozzle 122g is slightly recessed to form a minute segment portion 122h. The nozzle 122g is inserted into the main path 213a from the opening 202a. In the nozzle 122g, the nozzle supporting member 224 holds the side surface of the nozzle 122g after the insertion, and blocks the gap between the nozzle supporting member 224 and the nozzle 122g. Thereby, the inner space of the inserted nozzle 122g and the vent hole 220a of the valve body 220 are brought into communication. Further, the front end of the inserted nozzle 122g allows the valve body 220 to move toward the branch path 213b side. Here, by engaging the minute portion 221b of the valve body seal 221 with the minute portion 122h of the nozzle 122g, the valve body 220 pressed by the nozzle 122g does not hit the spring receiving portion 213d. Therefore, the valve body spring 219 is not deformed to block the main path 213a. Thereby, the inner space of the nozzle 122g and the vent hole 220a and the main path 213a are brought into communication. Further, by the valve body 220 moved by the nozzle 122g, the locus of the one-dot chain line of Fig. 6 is formed. When the nozzle 122g is separated from the main path 213a, the valve body spring 219 presses the valve body 220 toward the opening 202a side to block the main path 213a.

Here, a modification of the second valve portion 212 will be described based on the eighth and ninth drawings. Fig. 8 is a left sectional view of the communication path 213. The second valve portion 212 includes a check valve 212a. The check valve 212a is composed of a valve ball 225 and a valve body seal 221 . The valve ball 225 is disposed in place of the valve body 220 and has a true spherical shape. The valve ball 225 is pressed toward the opening 202a by the pressure of the compressed gas in the valve body spring 219 and the communication passage 213, and is pressed against the edge of the through hole 221a. By interrupting the main path 213a.

Fig. 9 is a left sectional view showing a communication path 213 in a state in which the unit is mounted by the mounting portion 122f. In the present modification, the notch 122i is formed at the tip end of the nozzle 122g. When the nozzle 122g is inserted into the main path 213a from the opening 202a, the gap between the nozzle support member 224 and the nozzle 122g can be blocked. Further, the tip end of the nozzle 122g after the insertion can move the valve ball 225 toward the branch path 213b side. Thereby, the inner space of the nozzle 122g is brought into communication with the main path 213a. Here, since the notch 122i is provided, the communication between the space inside the nozzle 122g and the main path 213a can be made reliable. Further, by engaging the minute portion 221b of the valve body seal 221 with the minute portion 122h of the nozzle 122g, the valve ball 225 pressed by the nozzle 122g does not hit the spring receiving portion 213d. Therefore, the valve body spring 219 does not deform and blocks the main path 213a. Further, by the valve ball 225 moved by the nozzle 122g, the trajectory of the dot chain line of Fig. 8 is formed. When the nozzle 122g is separated from the main path 213a, the valve body spring 219 presses the valve ball 225 toward the opening 202a side to block the main path 213a.

Here, when the valve ball 225 shown in FIGS. 8 and 9 is pressed by the pressure of the compressed gas in the communication passage 213 and pressed against the valve body seal 221, the valve body spring 219 can be omitted. However, by providing the valve body spring 219, when the nozzle 122g is separated from the main path 213a, the valve ball 225 can be quickly moved toward the opening portion 202a, and the main path 213a can be immediately blocked.

Further, the contact portion between the valve body seal 221 and the valve ball 225 may be an inclined surface that is inclined with respect to the through hole 221a as in the receiving portion 215a of FIGS. 6 and 7.

Returning to the description of the first embodiment. Fig. 10 is a left sectional view showing the cylinder mounting tool 201 in a state in which the gas cylinder 102 is attached to only one of the cylinder mounting portions 210. In Fig. 10, the portion filled with compressed gas air is filled with dots. The user introduces the gas cylinder 102 from the gas cylinder introduction port 204 (see FIG. 1) into the arrangement space 204a. At this time, the first end portion 102a is close to the cylinder mounting portion 210, and the second end portion 102d is close to the cylinder presser 206. Next, the user rotates the handle 208 to move the cylinder presser 206 toward the cylinder mounting portion 210. Thereby, the needle portion 217a of the unsealing member 217 is pierced by the sealing material 102c of the gas cylinder 102 (see also FIG. 4). Then, the compressed gas in the gas cylinder 102 is ejected and enters the vent hole 217d, and the valve ball 214 is separated from the valve ball seal 215. Thereby, the compressed gas flows into the main path 213a through the branch path 213b, and the air pressure in the communication path 213 is immediately increased.

Here, in the cylinder mounting portion 210 (the cylinder mounting portion 210 on the left side of FIG. 10) in which the gas cylinder 102 is not attached, the valve ball 214 is pressed by the air pressure in the communication passage 213, and is pressed against the valve ball. The receiving portion 215a of the seal 215. Therefore, the compressed gas does not leak out from the cylinder mounting portion 210 of the gas cylinder 102.

Further, in the second valve portion 212, the valve body 220 is pressed by the valve body spring 219 to block the main passage 213a. Therefore, the compressed gas is not leaked from the unit mounting portion 202.

Fig. 11 is a left sectional view showing the cylinder mounting tool 201 in a state in which the gas cylinders 102 are attached to all of the cylinder mounting portions 210. In Fig. 11, the portion filled with compressed gas is filled with dots. The user also installs the gas cylinder 102 in the same order for the cylinder mounting portion 210 in which the gas cylinder 102 is not installed. Thereby, the compressed gas enters the communication path 213 from any of the cylinder mounting portions 210.

Fig. 12 is a left sectional view showing a state in which the cylinder mounting tool 201 (the gas cylinder 102 is attached to all of the cylinder mounting portions 210) is coupled to the air chamber casing 122. In Fig. 12, the portion filled with compressed gas is filled with dots. The user inserts the nozzle 122g provided in the air chamber casing 122 into the opening portion 202a of the unit mounting portion 202. Thereby, the gas introduction path 122e in the gas cell casing 122 and the communication path 213 in the cylinder mounting tool 201 are brought into communication. Further, a gas introduction portion 301 is formed to guide the compressed gas into the gas chamber 126 from the cylinder mounting portion 210 attached to the cylinder mounting portion 210. Further, in the present embodiment, as described above, the gas introduction portion 301 is separably separable by the unit-mounted portion 122f and the unit mounting portion 202. Further, each time the user pulls the trigger 105 (see FIG. 1 and the like) and fires the projectile B (see FIG. 1 and the like) from the muzzle 103 of the toy gun 101 (see FIG. 1 and the like), the compressed gas is introduced through the gas. The portion 301 is supplied from the gas cylinder 102 and is filled in the gas chamber 126.

Fig. 13 is a left sectional view showing a state in which the cylinder mounting tool 201 (only the gas cylinder 102 is attached to one of the cylinder mounting portions 210) is coupled to the gas chamber casing 122. In Fig. 13, the portion filled with compressed gas is filled with dots. As shown in Fig. 10, even if the cylinder mounting device 201 in which the gas cylinder 102 is attached to only one of the cylinder mounting portions 210 is attached to the plenum housing 122, the user can use the toy gun 101 without any problem. This is because, as described above, the compressed gas does not leak out of the cylinder mounting portion 210 from which the gas cylinder 102 is not installed. Further, even if the user installs the cylinder mounting device 201 in which the gas cylinder 102 is installed in the entire cylinder mounting portion 210 to the toy gun 101 and then removes one gas cylinder 102, the compressed gas does not cause the cylinder of the gas cylinder 102 to be never installed. The mounting portion 210 leaks out.

Further, when the user removes the cylinder mounting tool 201 from the nozzle 122g, the valve body spring 219 presses the valve body 220 toward the opening 202a side to block the main path 213a. Thereby, the compressed gas in the gas cylinder 102 is prevented from leaking from the opening portion 202a.

As such, the toy gun 101 of the present embodiment can be provided with a plurality of gas cylinders 102. Further, the cylinder mounting portion 210 can be closed by the first valve portion 211. Therefore, the toy gun 101 can use a plurality of small gas cylinders 102 without using a large gas cylinder 102. Therefore, the toy gun 101 can be used for a long time without replacing the gas cylinder 102. Moreover, the portability of the gas cylinder 102 can be improved. Further, by miniaturizing the gas cylinder 102, the elastic design of the toy gun 101 can be achieved. Moreover, by closing the first valve portion 211, the projectile B can be fired from the toy gun 101 even if only one gas cylinder 102 is attached to the cylinder mounting device 201.

Further, the toy gun 101 of the present embodiment includes the check valve 211a in the first valve portion 211. Therefore, the user does not need to open and close the first valve portion 211 when loading and unloading the gas cylinder 102.

In the toy gun 101 of the present embodiment, the cylinder mounting portion 210, the first valve portion 211, the unit mounting portion 202, and the second valve portion 212 are unitized to belong to the cylinder mounting tool 201. Therefore, the usability of the cylinder mounting tool 201 can be improved.

Further, in the toy gun 101 of the present embodiment, even if the bottle mounting tool 201 is detached from the nozzle 122g or a plurality of gas cylinders 102 are detached from the cylinder mounting tool 201, the compressed gas does not leak. Therefore, after the cylinder mounting tool 201 is detached from the nozzle 122g, the gas cylinder 102 originally installed in the cylinder mounting tool 201 can be used later. The cylinder mounting tool 201 that is detached in a state in which the gas cylinder 102 is attached can also be attached to the other toy gun 101.

Next, another embodiment will be described based on Fig. 14. For convenience of explanation, the present embodiment will be referred to as a second embodiment. In this case, the same portions as those in the first embodiment are denoted by the same reference numerals and their description will be omitted.

Fig. 14 is a left sectional view showing the toy gun 101 in a state in which all the cylinder mounting portions 210 are mounted. In Fig. 14, the portion filled with compressed gas is filled with dots. In the present embodiment, the elements corresponding to the cylinder mounting tool 201 of the first embodiment are integrally formed with the gas chamber casing 122. That is, the gas cylinder mounting portion 201a is formed to extend downward from the gas chamber casing 122 of the present embodiment. The storage space 203 is formed in the gas cylinder mounting portion 201a, and the components belonging to the cylinder mounting tool 201 such as the cylinder mounting portion 210 and the first valve portion 211 are housed therein. Here, in the present embodiment, the toy gun 101 does not include the second valve portion 212 (see FIG. 6 and the like). Further, the gas introduction path 122e and the main path 213a are shared. Further, the toy gun 101 is not provided with a spring receiving portion 213d (see Fig. 6) located at the boundary between the main path 213a and the branch path 213b.

The toy gun 101 of the present embodiment is also a plurality of small gas cylinders 102 that can be used in the same manner as the first embodiment. Therefore, the toy gun 101 can be used for a long time without replacing the gas cylinder 102. Moreover, the portability of the gas cylinder 102 can be improved. Further, in the toy gun 101 of the present embodiment, since the gas chamber casing 122 and the gas cylinder mounting portion 201a are not separable, the cylinder mounting tool 201 (refer to the first embodiment) is not lost.

Next, another embodiment will be described based on Fig. 15 and Fig. 16. For convenience of explanation, the present embodiment will be referred to as a third embodiment. This embodiment is a second embodiment of the license. In this case, the same portions as those in the second embodiment are denoted by the same reference numerals and their description will be omitted.

Fig. 15 is a left sectional view of the cylinder unit 401. In the present embodiment, the gas chamber casing 122, the gas introduction portion 301, the cylinder mounting portion 210, the first valve portion 211, and the valve 123 are unitized into a cylinder unit 401. The cylinder unit 401 corresponds to the "installation tool" of the patent application. The cylinder unit 401 is detachably formed with respect to the gun frame 111. The structure of the cylinder unit 401 is the same as that of the air chamber casing 122 of the second embodiment. In other words, the cylinder unit 401 includes a gas chamber casing 122 through which the gas cylinder mounting portion 201a extends, and a valve 123 housed in the gas chamber casing 122. Further, the flange portion 302 extends from the side surface of the gas introduction portion 301.

Figure 16 is a left sectional view of the toy gun 101. Below the gun frame 111, a slit 111a for introducing the cylinder unit 401 from below is provided. The guide portion 111c extends from the edge of the slit 111a toward the inside of the gun skeleton 111. The guiding portion 111c is for guiding the cylinder unit 401.

A stopper 111d is provided on the side of the gun skeleton 111. The stopper 111d is slidable in the left-right direction of the toy gun 101 and can be moved by the user. The stopper 111d is a flange portion 302 for holding the cylinder unit 401 inserted from the slit 111a to prevent the cylinder unit 401 from moving in the up and down direction. Further, as shown in Fig. 16, the upper surface of the front portion of the stopper 111d can support the lower surface of the front end portion of the air chamber casing 122.

The holding projections 111e protrude from the left and right inner side faces of the gun skeleton 111. The left and right sides of the plenum housing 122 are sandwiched by the holding projections 111e to prevent the cylinder unit 401 from moving in the left-right direction of the toy gun 101. Further, the bolt 121 is formed in a shape that does not interfere with the holding projection 111e.

The user lifts up the cylinder unit 401 in which the gas cylinder 102 is attached to the gas cylinder mounting portion 201a, and introduces the gas chamber casing 122 of the cylinder unit 401 upward from the slit 111a. The chamber housing 122 is guided by the guide portion 111c and is located at a position coaxial with the barrel 113 and the valve 123. At this time, the air chamber casing 122 is sandwiched by the holding projections 111e. Next, the user moves the stopper 111d to hold the flange portion 302 by the stopper 111d. In this state, when the user pulls the trigger 105, the bolt 121 advances and the abutting portion 121e (see FIG. 2, FIG. 3, etc.) presses the sliding projection 123b (see FIG. 2, FIG. 3, etc.). The compressed gas of the gas chamber 126 is passed through the gas discharge portion 194 to push the projectile B out. As a result, the projectile B is emitted from the muzzle 103.

The toy gun 101 of the present embodiment is also similar to the first embodiment, and a plurality of small gas cylinders 102 can be used. Therefore, the toy gun 101 can be used for a long time without replacing the gas cylinder 102. Moreover, the portability of the gas cylinder 102 can be improved. Furthermore, the toy gun 101 of the present embodiment can replace the air chamber housing 122. Here, the plenum housing 122 has an air chamber 126 and a valve 123 that are important for the projectile B to be launched. Therefore, by replacing the cylinder unit 401, the user can enjoy various feelings through the toy gun 101.

As a modification of the third embodiment, as shown in Fig. 17, the magazine 112 can be attached to the side surface of the gas cylinder mounting portion 201a of the cylinder unit 401.

In the third embodiment and its modifications, the flange portion 302 (see FIGS. 15 and 16) and the stopper 111d are used for fixing and releasing the cylinder unit 401 of the gun frame 111 (see FIG. 16). In addition to, etc., the following methods can also be used.

Next, an example of fixing and releasing the cylinder unit 401 of the gun frame 111 will be described. A magazine release portion having a groove extending in the left-right direction is provided in the gun skeleton 111. The cylinder unit 401 inserted from the slit 111a is engaged with the groove. When the magazine release portion is moved, the engagement between the slot and the cylinder unit 401 can be released, and the magazine 112 can be removed.

Next, another example of fixing and releasing the cylinder unit 401 of the gun frame 111 will be described. A magazine receiver having a claw portion and an operating lever portion is coupled to the gun frame 111. The claw portion of the magazine receiving member is retractable with respect to the lower surface of the valve 123 to support the lower surface of the valve 123. The claw portion is drilled into the lower surface of the valve 123 by pressing the magazine receiver by a spring or the like. When the user moves the operation lever portion, the claw portion is retracted from the lower side of the valve 123, and the cylinder unit 401 is freely insertable with respect to the slit 111a. When the user's hand releases the operating lever portion, the claw portion moves to support the lower surface of the valve 123. Thereby, the cylinder unit 401 is fixed to the gun skeleton 111.

In any of the first to third embodiments, the toy gun 101 belongs to the continuous firing mode of the projectile B as long as the trigger 105 is continuously pulled, but the present invention can of course be applied to the single-shot toy. A toy gun with a gun and a burst.
