[0002]
[Prior art]
An electric toy gun that obtains air (compressed air) for firing a bullet by a piston-cylinder device is known, and the present applicant has also filed Japanese Patent Application Laid-Open No. Hei 6-235597 and has commercialized it. . However, in the case of the conventional electric toy gun, the piston cylinder device and the barrel are arranged on the same axis, so that it becomes longer in the front-rear direction, so that the type of gun that can be modeled is limited. It was.
[0003]
On the other hand, it is not unthinkable to arrange the piston cylinder device not on the barrel side but on the grip side, but in that case, the problem is what to do with the power supply. Conventional electric toy guns have a battery inside the grip part or an external power supply. However, if they are built in, the battery and piston cylinder device will be housed in the grip part, and the capacity of the piston cylinder device and the battery capacity will become increasingly insufficient. And practicality is poor.
[0004]
[Problems to be solved by the invention]
The present invention has been made paying attention to the above points, and an object thereof is to provide an electric toy gun in which the types of guns that can be modeled are not limited. Another object of the present invention is to provide an electric toy gun that can obtain necessary and sufficient power without arranging a piston-cylinder device coaxially with a barrel and that can easily accommodate a power battery. .
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a piston cylinder part as a mechanism that allows a compressed air to be injected and fired onto a bullet arranged in a bullet part at the rear of the barrel, and the piston cylinder part is driven. In the toy gun that performs the operation electrically, a nozzle having an air passage for injecting compressed air to the bullet of the bullet loading unit is arranged behind the barrel having the bullet loading unit so that the bullet can be loaded into the bullet loading unit. In addition, the nozzle is provided in a state where it can be moved forward and backward at the rear part of the barrel and urged forward, and the piston cylinder part is disposed on the grip part side of the gun body, and at the position where it communicates with the air passage of the nozzle when the nozzle advances , established the cylinder outlet of the piston cylinder device, provided with a motorized mechanism for accumulating the firing spring with the retraction of the piston to the grip portion, for supplying power to the electric mechanism power To, in which took measures that shall have the structure arranged in the barrel portion along the battery barrel.
[0006]
This toy gun has a piston cylinder part as a mechanism for injecting compressed air to a bullet placed in the rear part of the barrel and allowing it to be launched, and the piston cylinder part is driven electrically. Then, it has commonality with the conventional one. However, in the present invention, the piston cylinder portion has an electric mechanism for accumulating the firing spring as the piston moves backward, and the accumulated force of the firing spring is used instead of the electric mechanism when the piston moves forward.
[0007]
In this invention, a piston cylinder part is provided in the grip part side of a gun main body with the electric mechanism which drives this. By providing the piston cylinder part and the electric mechanism on the grip part side, it becomes easy to apply the present invention to a pistol type toy gun having a relatively short length behind the barrel part, and the length behind the barrel part Since the present invention can also be applied to a long toy gun, the types of toy guns that can be modeled vary.
[0008]
In the present invention, as a power source for supplying power to the electric mechanism, a battery is arranged along the barrel in the barrel portion. This power supply battery is preferably provided at an appropriate location around the barrel, and is preferably mounted inside the gun body. However, it is also possible to take a form in which a casing having an outer shape as a part of a gun is formed, a power supply battery is built in, and the casing is attached to and detached from the gun body.
[0009]
Compared with the conventional piston cylinder device that is coaxial with the barrel, the piston cylinder part is set to have a relatively large cross-sectional area and a relatively short stroke, so that the cylinder capacity cannot be significantly different from the conventional device. Has been. For this reason, the amount of compressed air that can be used in one firing stroke is not much different from the conventional one, and the same launching ability is maintained.
[0010]
The electric mechanism for accumulating the firing spring acting on the piston includes a gear set for transmitting the rotation of the motor to the piston, and the toothless portion provided in the sector gear therein is used as a quick return portion to It is desirable to have a configuration that releases accumulated pressure. Although this configuration itself is not exceptional, in order to advance the piston as fast as possible, the present invention uses a stronger firing spring, so the deceleration by the gear set of the electric mechanism can also accommodate the stronger firing spring. It will be something.
[0011]
In addition, in order to make it possible to load bullets into the loading part, there is provided a nozzle retreating part for retreating a nozzle for injecting compressed air to the bullet of the bulleting part, and the nozzle retreating part is interlocked with the sector gear. Can be taken. Since the sector gear rotates each time a bullet is fired, the nozzle can be moved backward by interlocking with the sector gear to temporarily open the space between the loading parts and feed the bullets one by one. it can.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, reference numeral 11 denotes a main body of a pistol-type toy gun, which has a barrel portion provided with a barrel 12 therein, and a grip portion 13 located at a lower rear portion thereof.
[0013]
In the rear end portion of the barrel 12, there is provided a loading portion 14 capable of locking a single bullet B. A nozzle 15 for injecting air toward the loading portion 14 is provided behind the loading portion 14. It is provided so as to be able to move forward and backward and biased forward by a spring 16. The upstream end of the air passage in the nozzle is opened and communicates with the discharge port 18 of the cylinder 17 of the piston cylinder portion. The cylinder 17 secures the maximum displacement by making it as large as possible in the internal space of the grip portion 13, and is provided so that air is ejected to the bullet loading portion 14 with almost no resistance. Reference numeral 19 denotes a spring receiving member.
[0014]
A piston 21 is slidably fitted into the cylinder 17, and a seal ring 22 shown as an O-ring is attached to the sliding portion. The piston 21 has a piston rod 23 extending in the sliding direction, a rack 24 is provided along the outside of the piston rod 23, and the piston 21 has a powerful launch to urge the piston 21 in the front direction. The spring 25 is acting. The other end of the firing spring 25 is supported by a spring receiver 26 provided below the piston 21 so as to be extendable and contractable with respect to the piston 21.
[0015]
The rack 24 is provided so as to be able to mesh with the sector gear 27 of the gear set 30 and not mesh with the toothless portion 28 thereof, and the gear set including the sector gear 27 has a motor 29 constituting an electric mechanism at its end. Meshes with the output gear attached to the shaft. The motor 29 is attached to a position where it can be communicated with the rack 24 on the piston side by a gear set 30 so as to fit in the lowest space in the grip.
[0016]
Further, in order to retract the nozzle 15 for injecting compressed air against the spring 16 so that the bullet B can be loaded into the loading part 14, the nozzle retracting part 31 communicates with the gear set 30 and the nozzle 15. Is provided. The illustrated retreating portion 31 includes a nozzle communication rotating projection 32 provided coaxially with the sector gear 27, a nozzle communication rod 33 pushed up by the rotation of the projection 32, and a cam 34 rotated by the rod 33. And a connecting portion 35 that engages with the cam 34 and receives the rotation to retract the nozzle side member.
[0017]
Due to the backward movement of the nozzle 15, a bullet supply part 36 for arranging the bullet B between the nozzle tip and the bullet loading part 14 is provided at a position closer to the front of the grip part 13. The bullet supply unit 36 illustrated as an example extends obliquely from the lower part of the grip toward the rear part of the loading unit, and includes an extruding part 37 that extrudes the bullet B and a pushing spring 38 that extrudes the bullet B in the extruding direction.
[0018]
A mechanism for interlocking the piston cylinder portion and the retreating portion 31 for loading bullets by operating the trigger 41 is provided. Reference numeral 42 denotes a trigger bar for connecting the trigger 41 and the movable switch contact piece 43, and 44 denotes a switch terminal. The switch contact piece 43 is brought into contact or separated by a trigger operation. Reference numeral 45 denotes a trigger contact, which is operated by a mode selector 46 that switches the firing mode between the full auto mode and the semi auto mode. In the full auto mode, a part of the cutoff member 47 does not come into contact with the trigger contact 45. This enables continuous firing.
[0019]
In the present invention, a battery is provided in the barrel portion along the barrel as the power supply portion 48 for supplying power to the motor 29 constituting the electric mechanism. The illustrated power supply unit 48 is constituted by two rows of battery groups, and is disposed obliquely with the interior of the space below the barrel 12 as the accommodating unit 40, connected to the electric mechanism by cordless wiring, and attached and detached at the connector portion. Can be charged or replaced. Reference numeral 53 denotes a detachable upper cover having an outer shape imitating a pistol slide. Thus, the battery of the power supply unit 48 is integrated into the gun body 13 in a state in which the battery is incorporated in the housing unit 40 under the barrel, prevented from being pulled out upward by the engaging unit 54, and further covered by the upper cover 53. Is in a state.
[0020]
The operation of the electric toy gun 10 of the present invention configured as described above will be described with reference to FIG. FIG. 3 shows a semi-automatic mode and a state before firing. When the trigger 41 is pulled, the trigger bar 42 moves forward, the switch contact piece 43 comes into contact with the switch terminal 44 and becomes energized. 29 is energized and the gear set 30 begins to rotate. It is the state of FIG.
[0021]
The piston 21 is compressed by the sector gear 27 that meshes with the rack 24, and the firing spring 25 is compressed. At the same time, the connecting rod 33 is pushed up by the rotating projection 32 that rotates simultaneously with the sector gear 27 and pushes the connecting portion 35 of the nozzle side member back via the nozzle cam 34 (FIG. 5). Retreats, and one bullet B is supplied to the loading chamber 14. Thereafter, the nozzle 15 is advanced by the spring 16 to complete the loading.
[0022]
When the piston 21 is retracted to the limit and the sector gear 27 is disengaged from the rack 24, the firing spring 25 performs a rapid forward movement, but immediately after the sector gear 27 is disengaged from the rack 24, the cut-off member 47 is moved to the sector. Since it is pushed up by a part 55 of the gear 27 and the connector 45 on the trigger side is pushed up, the switch contact piece 43 is returned and separated from the switch terminal 44 to stop power feeding. It is the state of FIG. Since the piston 21 receiving the accumulated pressure of the firing spring 25 moves forward rapidly and compresses the air in the cylinder 17, the compressed air passes through the discharge port 18 and the nozzle 15, and the bullet B held in the loading chamber 14. Will act and fire.
[0023]
When the mode selector 46 is switched to the full auto mode (FIG. 7), the contactor 45 moves and does not come into contact with the cut-off member 47, so that the electric mechanism is always in a power supply state and while the trigger 41 is being pulled. The sector gear 27 continues to rotate, and the backward movement of the piston 21 and the forward movement by the firing spring 25 are repeated. As the sector gear 27 rotates, the bullets B are loaded into the loading unit 14 one by one. Therefore, in the full auto mode, the bullets B are continuously fired. In the electric toy gun of the present invention, since the power source battery is arranged in the barrel part, the front is heavier compared to a toy gun that does not have a power source battery in the barrel part. It also contributes to restraining the gun from shaking.
[0024]
【The invention's effect】
Since the present invention is configured and operates as described above, the piston cylinder part and the electric mechanism can be arranged on the grip part side, and the types of guns that can be modeled are various, and as in the conventional case. Even if the piston cylinder part is not arranged coaxially with the barrel, the necessary and sufficient power can be exerted, and the battery of the power source can be easily stored, so that the outer shape of the gun is not damaged.
