Description

[Detailed description of the invention] "Industrial application field" This invention relates to a bullet firing device for a toy gun.
In particular, the present invention relates to a bullet firing device for a fully automatic toy gun that continuously fires bullets using a pressure medium such as compressed air or low-pressure gas.

``Prior Art'' Conventionally, this type of bullet firing device warms the valve of a supply cylinder connected to the gun body via a hose.
When the trigger is pulled with water, the foot lever is released from the hook provided on the piston member, and the piston member reciprocates due to changes in the pressure medium supplied from the supply cylinder, thereby releasing the bullets sent from inside the magazine. It was constructed in such a way that when continuous firing was performed, and the valve of the supply cylinder was closed, the movement of the piston member of the power unit was stopped, and as a result, the bullets were not fired.

However, in the above configuration, when the valve is tightened, the piston member immediately stops at any position, or there is a possibility that the piston member stops, and the nozzle of the piston member is located at an inappropriate location in the bullet inlet. As a result, the piston member often malfunctioned in the next firing round. Furthermore, the launcher with the above configuration had only a fully automatic function and lacked interest.

``Problems to be Solved by the Present Invention'' In view of the above-mentioned drawbacks of the conventional systems, the present invention has developed a mechanical system that starts and stops the power unit immediately by operating a trigger without having to warm up or tighten the valve of the supply cylinder. When the power unit is stopped, the piston member is securely stopped in the predetermined position to prevent malfeeding, and furthermore, it can be changed from full auto to semi-auto by simply operating the selection lever. Or, to obtain a firing device for a toy gun which can be freely changed from semi-automatic to fully automatic, and which can be manufactured at low cost by reducing the number of constituent parts.

``Means for Solving Problems'' This invention is a trigger for a bullet firing device in a fully automatic toy gun that continuously fires bullets sent from a magazine by reciprocating a piston member using a pressure medium. a long hook piece that engages with the piston member to completely stop the piston member when it is in an initial state, and releases the engagement and starts the piston member when the trigger is pulled; and this long hook piece. As the piston rotates, it rotates in the direction of locking the piston member, temporarily stopping the backward movement of the piston member that fired a single bullet, and in semi-automatic mode, the short hook piece is freely released. A selection lever is provided.

``Embodiment of the Present Invention'' Hereinafter, in an embodiment shown in the drawings, reference numeral 1 indicates a gun body of a toy gun, and for convenience, illustration of other non-essential parts is omitted. Reference numeral 2 denotes a cylinder of a power unit provided inside the gun body 1, and a pressure medium 3 such as compressed air or low-pressure gas is sent to the cylinder 2 from a supply cylinder (not shown) via a hose. 4 is a piston member that reciprocates within the cylinder 2 by means of a pressure medium, and this piston member 4
A lock bar 6 is integrally provided at the tip of the nozzle 5 and extends downward from the outer circumferential wall of the tip of the cylinder 2. Reference numeral 7 designates an engaging protrusion formed at an appropriate location on the horizontal portion of the lock bar 6. Reference numeral 8 denotes a long hook piece that is pivoted on the gun body 1 and rotates when the trigger 9 is operated.A claw 8a that engages with and disengages from the engagement protrusion 7 is formed at one end of this long hook piece 8. The long hook piece 8 is always urged by the pivot 11 in the direction in which the claw 8a engages with the engagement protrusion 7 of the lock bar. 10 is a long hook piece 8
between the pivot 11 of the gun body 1 and the claw 8a.
The short hook piece 10 is always locked by a selection lever 12 that is pivoted at a position below the long hook piece 8 when the toy gun functions as a fully automatic type. A claw 10a that engages with and disengages from the engagement protrusion 7 is also formed on the part, and the short hook piece 10 is always moved in the direction in which the claw 10a engages with the engagement protrusion 7 of the lock bar by a spring provided on the pivot shaft 13. energized. Reference numeral 14 denotes a boss portion that projects from the outer surface of the short hook piece 10 near the other end and comes into contact with the inner circumferential wall of the long hook piece 8. Note that B1, B2, and B3 are a large number of bullets that are sent one after another from a magazine (not shown) to the bullet injection port side where the packing member 15 is provided. Also S
A spring member is provided in the cylinder 2 of the power unit and biases the piston member 4 rearward.

In the above structure, when the toy gun is to be used as a fully automatic gun, first, as shown in FIG. The short hook piece 10 is prevented from rotating in the direction of the hour hand by a spring provided therein.

Therefore, when the trigger 9 is in the initial state, or when the trigger 9 is stopped being pulled, the trigger 9
returns to its original state, the long hook piece 8 is attached to the pivot 1
1 is rotated in the direction of the hour hand, and its pawl 8a engages with the engaging protrusion of the retracting piston member 4. Therefore, the piston member 4 that was reciprocating within the cylinder 2 by the pressure medium 3
is locked by the long hook piece 8, and its backward movement by the spring member S is prevented. In this case, the tip of the piston member 4 opens the bullet introduction port 17 of the bullet introduction path 16, and the bullet B1 located at the lowest position in the bullet introduction path 16 falls into the bullet injection port of the packing member 15.

On the other hand, when the trigger 9 is pulled in the direction of the arrow a shown in FIG.
is removed from the engagement protrusion 7 of the lock bar 6. In this case, the short hook piece 10 remains locked to the selection lever 12 and is not affected in any way by the rotation of the long hook piece 8. The piston member reciprocates due to changes in the pressure medium 3, and continuously fires bullets set in the packing member 15 from the bullet injection port one after another.

Next, when the toy gun is used as a semi-automatic gun, the selection lever 12 is manually switched from the position shown by the solid line in FIG. This allows axis 1
The short hook piece 10, which is about to rotate in the direction of the hour hand by the spring 3, is released from the selection lever 12, but
Since the boss portion 14 is in contact with the inner circumferential wall of the long hook piece 8, its rotation is still prevented.

When the trigger 9 is pulled in the direction of the arrow a as shown in FIG.
is disengaged from the engaging protrusion 7 of the lock bar 6, the piston member 4 is moved toward the rear side of the cylinder 2 by the spring member S, and begins to move forward again by the pressure medium 3. On the other hand, the short hook piece 10 is rotated in the direction of the hour hand by the spring force of the pivot shaft 13 because the tip side of the long hook piece 8 is downwardly moved. and,
As the piston member 4 advances toward the bullet injection port,
On the way, the claw 10a of the short hook piece 10 and the engagement protrusion 7 of the lock bar 6 abut each other,
The claw 10a of the short hook piece passes over the engagement protrusion 7 of the lock bar. Furthermore, as shown in FIG. 4, the piston member 4 moves forward and the tip end of the piston member
7 is closed, and bullet B is set in the packing member 15.
1 with pressure medium 3, then piston member 4
When the hook moves backward, the short hook piece 10 that has climbed over the engagement protrusion 7 first waits for the engagement protrusion 7 of the lock bar 6, and as shown in FIG.
Temporarily stop the backward movement of. In this case, the trigger 9 remains pulled, and the piston member 3 is temporarily stopped. Also, the next bullet B2 in the bullet introduction path 16
The bullet introduction port 17 opens due to the retreat of the piston member 4, and the bullet falls into the bullet injection port.

However, if the trigger 9 is kept pulled, the piston member 4 is temporarily stopped, but the trigger 9
When the long hook piece 8 is returned to its original position, the long hook piece 8 rotates in the direction of the hour hand, and as the long hook piece 8 rotates, the inner peripheral wall of the long hook piece 8 pushes up the boss portion of the short hook piece 10, and as a result,
The short hook piece 10 rotates in the counterclockwise direction and disengages from the engagement protrusion 7 of the lock bar 6. At this time, the piston member 4 starts to move rearward due to the spring force of the spring member S, but before that, the claw 10a of the long hook piece 8 comes into contact with the outer peripheral wall of the lock bar 6, and the engagement protrusion 7 moves back. I'm waiting for it to come. When the piston member moves backward, it is locked by the long hook piece 8 and comes to a complete stop as shown in FIG. From then on, bullets are fired one by one in a semi-automatic manner using this operating mode.

"Effects of the present invention" As is clear from the above explanation, the present invention has the following effects.

(1) Simply switch the selection lever to switch the toy gun from full-auto to semi-auto.
Or it can convert from semi-automatic function to fully automatic function. (2) When the short hook piece is locked with the selection lever and the trigger is pulled, the piston member automatically reciprocates and the bullets are fired continuously (full auto).
Then, when the trigger is returned to its original state,
The long hook piece immediately engages the piston member;
The piston member comes to a complete stop, even though pressure medium continues to be supplied into the cylinder from the supply cylinder.

(3) On the other hand, when the short hook piece is unlocked with the selection lever and the trigger is pulled, the piston member that has fired one bullet is temporarily stopped by the claw of the short hook piece while moving backward, Further, when the trigger is returned to its original state, the short hook piece disengages from the piston member as the long hook piece rotates, and then the long hook piece engages with the piston member to completely stop the piston member. .

(4) Therefore, the piston can be mechanically started and stopped simply by operating the trigger, and the above (1)
Or (3) doubles the fun of toy guns.

(5) In the case of an embodiment in which the piston member is integrally provided with a lock bar that engages with a long hook piece at a predetermined position when the trigger is returned to its original position, for example, if the nozzle of the piston member opens the bullet inlet Since the long hook piece can be engaged with the long hook piece at an appropriate location, there is no possibility of malfeeding of bullets from the bullet inlet.

(6) Since the number of constituent parts is small, it can be manufactured at low cost.
