Description

Description: The present invention relates to a bullet electric launching device for a portable toy gun, which carries out a single shot or multiple shots of plastic bullets. It is mounted on the idle shaft by using rotational force to displace the displacement idler by screwing with the screw, or converting the rotary motion of the gear into a linear motion like a piston through several stages of gears. When a displacement is caused in the displacement idler, the displacement generates a stress by compressing a stress generating means, for example, an air pump chamber, a spring, etc. The plastic bullet loaded in the barrel hole by an appropriate method is instantaneously transmitted to release the stress, and then fired. After the firing, the rotational force of the motor is used again to return the displacement locomotive to its original position. TECHNICAL FIELD The present invention relates to a bullet electric launching device for a portable toy gun, which is capable of single-shot or multiple shots of plastic bullets that are controlled and driven, and can also be repeatedly moved.

Conventionally, most of the bullet launching devices for toy guns of this type are single-shot ones even if they are spring type or gas type, and furthermore, the stress is generated by the stress generating means for performing the shooting once every time. It had to be operated by hand, which was a major obstacle to gunplay, which was extremely complicated and competing for speed.

So, a gas gun using air, CFC gas, etc. was born, but this was also equipped with a gas cylinder,
It requires time-consuming and complicated work such as replacement and pressurization of high-pressure air. Especially, CFC has recently been called for depletion of the ozone layer in the stratosphere, and its use has become a problem. On the other hand, the convenient property of vaporizing is that it is difficult to vaporize at low temperature, especially, it does not vaporize below freezing, and a toy gun that uses gas pressure is completely unusable in winter or in the low temperature regions of Tohoku and Hokkaido. It was a possible and fatal flaw. Here, single-shot or multiple-shot type that can be used in all seasons and low temperature areas,
Moreover, the industry and all users were eager to develop an automatic bullet launcher that does not require the operation to obtain a complicated and complicated source of firing stress, and its development was urgent. .

On the other hand, Japanese Examined Patent Publication No. Sho 36-230 proposes a simulated machine gun operated by compressed air.

The mechanism of this simulated machine gun is a very large one that employs a piston structure and fires a bullet by compressed air, and the energy to actually fire the bullet does not reach that of a real bullet. It requires about 5 joules, which is why we have to take a large structure called a clutch mechanism, let alone consider the fact that it is heavy and is not portable, etc. It was used in the installed state, far from a toy gun, not easy to play, and its mechanism was expensive and its operation was not satisfactory.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a detailed description of a portable electric toy gun bullet electric launching device for single-shot or multiple shots of a plastic bullet according to the present invention, with reference to the drawings. All bullets used here are plastic.

First, the above-mentioned device when the air pump chamber 1 is used as a stress source will be described.

As shown in FIGS. 1 and 2, the floating shaft 5 directly connected to the motor 3 fixed to the base plate 2 is rotatably mounted so as to penetrate through the center of the air pump chamber 1 in an airtight manner. The displacement idler 9 is screwed to the screw portion of the resistor 45. Now, if the trigger 7 is pulled, the switch 8 is closed, and the motor 3 is rotated in the normal direction, the floating shaft 5 rotates and the displacement slider 9 is screwed toward the air pump chamber 1 to compress the air. Displace it as it goes. Since the air pump chamber 1 and the displacement idler 9 are fitted so as to completely maintain airtightness, and the air valve 68 is pressed by the valve spring 69 to close the pump air discharge hole 10, the displacement idler 9 The air pressure in the air pump chamber 1 rises with the displacement of the air pump chamber 1, and when the required pressure is reached, the pump air release hole 10 and the idler air release hole 11 are aligned while pushing the air valve 68. ，
Since 11 is closely connected to the air guide tube 12,
After passing through this, an instantaneous jetting force is given to the filled plastic bullet 15 from the magazine 13 at the tip thereof so that the plastic bullet 15 is fired.

Thus, the plastic bullet 15 passes through the barrel hole 16 and is fired from the muzzle at a predetermined speed. At the same time, when the tip of the displacement idler 9 pushes the switch 18, the motor 3 stops rotating, and the motor 3a coaxially fixed at a position opposite to this starts rotating. Although this rotation direction is a normal direction, it is the opposite direction to the rotation direction of the motor 3 which is facing. However, the motor 3 and the motor 3a are set so as not to interfere with each other by idling when the opponent rotates.

As a result, the displacement idler 9 starts to return to the original position while screwing on the idle shaft 5, and when the displacement is complete, the pump air intake hole 19 and the idler air intake hole 20 are aligned. Then, the outside air is taken into the air pump chamber 1. At the same time, in case of continuous operation, the action rod 30 pushes the switch 21 to stop the rotation of the motor 3a and rotate the motor 3 again, and the displacement idler 9 starts compressing the air in the air pump chamber 1.

Switch between single-shot mode and continuous-shot mode is performed by the switch 22 for single-shot mode switching
In the case of the motor 3 which is put in a single shot, the motor 3 does not start rotating even when the action rod 30 presses the switch 21, and all the operations are stopped here.

Next, details of an embodiment in which a spring 23 is used as the stress generating means of the stress source will be described below with reference to the drawings.

As shown in FIG. 3 and FIG. 4, only one motor 3 is used. The motor 3 has a displacement screw 25 formed in the center thereof and is screwed with the displacement idler 9 fixed to one end of the spring 23. It is directly connected to the floating shaft 5. Now, when the trigger 7 is pulled and the switch 21 is turned on, the motor 3 starts rotating. As a result, the floating shaft 5 is supported by the floating shaft support 27 on one side, and the displacement idler 9 is screwed to the spring 2
Displace 3 to compress. At this time, spring 2
The other end of 3 is ring-shaped, and its forward movement is blocked by a locking hook 29 held by a retaining ring 17 connected to the spring pressure end portion 14 at one end thereof.
3 is gradually compressed, increasing its stress.

When the stress reaches a required stress, the locking hook 29 is pushed down by the action rod 30 provided on the displacement idler 9 to release the lock, and the spring 23 strongly jumps forward. At the tip of the spring 23, the pump inner cylinder 4 is in close contact with the spring pressure end 14 of the spring 23, and the four outer knobs 33 act as a secret while keeping the same in the pump outer cylinder 32. As the air pump chamber 1 is formed by fitting, the magazine 1 is held together with the detention bulletin of the spring 23.
The plastic bullet 15 sent from 3 is jetted from the muzzle together with the air jet. Displacement idler 9 together with the starting action
When the action rod 30 of the switch turns on the switch 18, the motor 3 starts reverse rotation, the floating shaft 5 is screwed, the spring 23 is returned together with the displacement idler 9, and the retaining ring 17 is retained by the retaining hook 29. It continues to return until it is stopped, and the action bar 30 of the displacement idler 9 turns on the switch 21.

At this time, if the switch 22 is in continuous operation, the motor 3 returns to normal rotation, and the displacement idler 9 moves to the spring 23.
Start compressing, repeat the above-mentioned firing and return operation, and if it is a single shot, stop the operation here.

Here, the mechanical principle when the air pump chamber 1 is used will be described.

As shown in FIG. 5, the air pump chamber 1 is now in a normal state, and the pressure inside the chamber is considered to be 1 ptm.

When the motor 3 starts rotating by pulling the trigger 7, the displacement idler 9 of the idle shaft 5 begins to compress the air in the air pump chamber 1. And the pressure gradually increases.

At this time, as shown in FIG.
If the length from the inner wall of the displacement idler 9 to the inner wall of the air pump chamber 1 is l, and that in normal times is L, the displacement idler 9 compresses air to give it to the length of l. The energy amount W _A is W _A = pv p is the pressure in the air pump chamber 1 at the position where the displacement armature 9 is 1.

v is the volume of the portion through which the displacement armature 9 has passed.

Therefore, if the above equation is expressed by L and l, Here, r is the inner diameter of the air pump chamber 1 and R is the inner diameter of the displacement idler 9. If this is regarded as R≈r, Here, the projectile energy is set within 0.4 joules (energy to fire 0.16g of plastic bullets at a speed of 70 / sec) according to industry agreement,
When the value corresponding to this is put and l is calculated, When L = 5 cm and r = 2.5 cm, the above is expressed in cm units. L = 1.9 cm≈2 cm The pressure inside the air pump chamber 1 at that time is P = 5/2 = 2.5 ptm / cm The force given to the displacement idler 9 is F = πr ² p ≈2.5 kg / cm × π / 4 × 2.5 cm × 2.5 cm = 12.25 kg This is the axis of the idle shaft 5 that is applied to the threaded portion of the idle shaft 5. The force in the direction of the screw becomes a load on the screw slope with a diameter of 6 mm and a pitch of 1 mm. This is the force required for the rotation shaft of the motor 3 as a rotation moment.

However, since the diameter of the floating shaft 5 is φ6 mm, its radius is 3
mm and the motor nominal moment is in g-cm units, In other words, it is sufficient for the motor 3 to obtain a motor having a nominal moment of 195g-cm ≈ 200g-cm.

Now, let us consider what kind of dynamic structure will be obtained when the spring 23 is used.

As shown in FIG. 6, the length of the spring 23 under normal conditions is set to L, the length when compressed until the required stress is obtained, the length during compression is x, and the spring constant is k. In fact, the energy when the spring is compressed to x is If 0.4 joule is set as W _s and L = 130 mm and l = 30 mm, then 0.4 = 1 / 2k (130-30) ² 0.8 / 0.01 = kkg / mm k = 80 / mm Become.

In other words, a spring that produces 80g of force per mm is required.

Therefore, the force required to make a displacement of 130mm-30mm = 100mm is F = kx and F = 80g × 100 = 8kg.

When the rotational force of the motor required to make the floating shaft 5 in the vertical direction is obtained, the same as when the air pump chamber 1 is used, Becomes

Therefore, a smaller motor than that in the case of the air pump chamber 1 is required, but this is a gain because the length of the spring 23 is 100 mm, which is twice the length 50 mm of the air pump chamber 1.

Thus, even in the case of the air pump chamber 1, the spring 23
It has been found that it is possible to use a small motor that turns on the battery 6v even when using the, and the bullet electric launching device of the toy gun of the present invention is stressed by the displacement idler 9 of the swinging idle shaft 5. To compress the source to gain energy,
It has been clearly shown that the force efficiency is extremely good and that it has a characteristic that a large force can be produced with a small stress source.

However, of course, if the motor 3 is further strengthened and it becomes possible to use something like a linear motor, the bullet electric launching device for a toy gun of the present invention can be used as a launching device for a toy gun having more functions. It is possible.

Here, an embodiment of the electric circuit of the bullet electric launching device for a toy gun of the present invention will be described with reference to FIGS. 7 and 8. FIG. Normal rotation and reverse rotation are performed by switching the polarity to +-. Since it is used to reduce the stress of the stress source even in reverse rotation, the load is reduced, and if the stress source is designed to be larger than the required output, it will serve as positive energy at the time of recovery and will be momentary. It also enables a return action,
It can withstand reverse rotation sufficiently.

Further, FIG. 8 shows that two motors, a motor 3 and a motor 3a, are used. When a stress source is stressed, it is rotated by the large motor 3 and when returning, the small motor 3a is used. There is.

This takes up a little space, but has the advantage of not giving the same motor the burden of reverse rotation.

In FIG. 7, when the trigger 7 is pulled, the switch 8 is closed, the assembled electric circuit is connected to the electric circuit board 6, the voltage is input to the resistor 34, the differential circuit is formed by the capacitor 35, and the trigger pulse is generated. The resistance 36 and the diode 37 act as a + trigger, and the SCR
Applied to the gate of 38.

As a result, radio waves flow to the SCR 38, the relay 39 operates, the contacts of the relay 40 and the relay 40a are closed, and the battery 4
The + terminal of the motor 3 is connected to +, and the − terminal of the motor 3 is connected to −, so that the motor 3 starts to rotate normally.

Next, when the displacement armature 9 compresses the stress source to reach the required stress, a device appropriately set for each of the air pump chamber 1 and the spring 23 presses the switch 18.

Therefore, this time, resistor 43, capacitor 44, resistor 4
5, the current flows through the SCR 47 due to the diode 46, and the relay 48 operates to activate the relay 4 of the motor circuit.
1. Turn on the relay 41a.

The switch 18 to which the input voltage is applied simultaneously inserts the resistor 49 into the circuit of the relay 39 to instantaneously drop the anode current below the holding current. Therefore, the SCR38 stops operating,
The relay 39 is released, the relay 40 and the relay 40a are opened, the polarity of the motor 3 is switched by the relay 41 and the relay 41a, the + terminal is + of the battery 42, and the − terminal is +.
Is connected to and starts reverse rotation.

Thus, when the trigger 7 of the floating shaft 5 returns to its original position, the switch 21 is pressed again. However, at this time, if the switch 22 is turned on, the switch 21 puts the resistor 50 in the circuit of the relay 48 and turns off the relay 48, so that the voltage is applied to the resistor 34 again and the motor 3 starts to rotate. If is not present, the motor 3 stops its rotation, and the idle shaft 5 and the displacement idler 9 stop at the normal position. In this way, single operation or continuous operation can be easily switched by operating one of the switches 22.
This is also a great feature of the bullet firing device of the toy gun of the present invention.

The circuit using two motors 3 and 3a is
This is as shown in FIG.

The switch 8 is turned on together with the trigger 7, the + trigger is applied to the gate of the SCR 55 by the resistor 51, the capacitor 52, the resistor 53 and the diode 54, and the motor 3 is rotated by the anode current.

Next, when the rotation reaches the time when the displacement idler 9 of the idle shaft 5 reaches the required stress, the switch 18 is closed, and this time the resistance 5 is reached.
6, a current flows through the motor 3a by the capacitor 57, the resistor 58, the diode 59 and the SCR 60, and the motor 3a starts rotating. At the same time, the other contact of the switch 18 is in the motor 3, which is momentarily opened to put the resistor 61 in the circuit to reduce the current below the holding current to stop the function of the SCR 55 and stop the rotation of the motor 3.

As shown in FIGS. 1 and 2, the motor 3a is the motor 3
Since it is located coaxially with respect to the shaft, the floating shaft 5 can be screwed back to the original position even if the normal rotation is performed.

In this way, when the displacement idler 9 completes the return movement together with the idle shaft 5, the switch 21 is pushed again to rotate the motor 3 and the resistor 67 is inserted in the circuit of the SCR 60 to turn off the motor 3a, but this is finished only once. Whether or not to continue by repeating can be performed by operating the switch 22 in exactly the same manner as described above.

In this way, regardless of whether one motor 3 is used or two motors are used, it is possible to operate the bullet electric launching device of the toy gun of the present invention without any hindrance, and various advantages in design are obtained. It is what you are giving.

Here, the case where the bullet electric launching device of the toy gun of the present invention slides instead of the idle shaft 5 for screwing will be mentioned.

As shown in FIG. 9, this is done through several stages of gears. If this dynamic relationship is also described, the force efficiency in the idle shaft direction due to screwing, fe = 1 rotation screw thread length / Pitch height = 6π x 1 = 18.84 is derived from the combination of gears based on the relationship between the number of rotations and the diameter of the gears. Sliding using the pump action by conversion into sliding motion by using the gear combination and crank action. Some embodiments will be described in detail with reference to FIG. 9, which basically illustrates the operating principle of the present application from the configuration of the pump action by conversion into motion.

As shown in the figure, the combination of the pinion gear 72 and the gear 62 mounted on the motor 3 is now set as fe ₁ = N ₁ / N ₂ = R ₂ / R ₁ = 10/3 = 3.3, and the gear 62 And the gear 63 in the second stage of the gear 63
Via: fe ₂ = N ₂ / N ₃ = R ₃ / R ₂ = 50/10 = 5, at the third stage of gear 64 and gear 65 coaxial with gear 63, via gear 70, fe ₃ = By setting N ₃ / N ₄ = R ₄ / R ₃ = 40/10 = 4, the power efficiency becomes fe = 3.3 × 4 × 5 = 66, and in case of screwing fe =
It is better than 3.3 × 18.84 = 62.172, and can be sufficiently dealt with even considering the loss due to the increase in load due to the rotation of gears and passing of the fulcrum of crank action.

Here, fe is force efficiency, N is the rotation speed of each gear, and R is the diameter of each gear.

Here, an embodiment of firing operation by a crank system will be described with reference to the drawings.

10 and 11 are pumps using the operating principle shown in FIG. 9 to use the spring 23 as a stress source and the pumping action shown in FIGS. 1 and 2 together. Inner cylinder 4
The pump outer cylinder 32 and the pump outer cylinder 32 are caused to perform a pumping action by converting the rotary motion into the sliding motion by the crank system, and the plastic bullet 15 is to be jetted by the jetting air.

This is the same operating principle as that shown in FIG. 3 and FIG. 4, but since the structure of converting the rotary motion into the sliding motion is used, the compressed spring 23 returns by itself and the pumping action is performed. Is configured to do.

As shown in FIGS. 10 and 11, when the trigger 7 is pulled now, the single switching device 24 that works together with the trigger 7 operates. This device controls the rotation of the motor 3 by a mechanical method to convert the rotary motion into the sliding motion by a mechanical method, and performs a switching operation of single-shot mode. When the trigger 7 is pulled, the trigger crank 26 Rotates about the pivot axis and the other end pushes the switch 8 to close the circuit. At this time, if the control pin 31 of the single switching plate 28 that is driven by the rotation of the external knob 33 is closer to the trigger 7, the trigger 7 stops by pressing the switch 8, the circuit remains closed, and the motor 3 continues to rotate. , This is a continuous operation. When this is rotated by the external knob 33 to rotate the single switching plate 28 to fit the gear 70 into the other notch, the control pin 31 is separated from the trigger crank 26 and the stroke of the trigger 7 becomes longer.
When the trigger 7 is pulled hard, the trigger crank 26 is pushed all the way down and it goes down as it is.
Is returned to the original state in an instant, and the switch 8 momentarily opens and closes the circuit and ends. In the single switching device 24,
Although not shown, a proper activation and return spring is incorporated to smoothen the single continuous operation of the trigger 7. Further, the single continuous switching device 24 is only one embodiment and various other types are conceivable. However, since they are not related to the gist of the present invention, many of them will be omitted.

The firing actuation mechanism will be described in detail with reference to the drawings. Figure 10,
As shown in FIG. 11 and FIG. 16, when the trigger 7 is pulled and the switch 8 is closed, the motor 3 starts to rotate and the gear 65
When the shaft starts to rotate in the direction of the arrow, the floating shaft 5 is pulled against the stress of the spring 23, the pump inner cylinder 4 fixed as a displacement idler is attracted to the tip of the shaft, and the pump outer cylinder 32 is hermetically sealed. The spring 23 is compressed while sliding smoothly. When the compressive stress reaches the required magnitude,
When the gear 65 almost completes a half rotation and just exceeds the conversion point (dead point) to the linear motion in the conversion operation of the rotary motion to the sliding motion, the rotation of the motor 3 returns the spring 23 without changing the rotation direction. Instead of the force to be exerted, in combination with the repulsive return stress of the spring 23, it instantaneously returns, the pump inner cylinder 4 also instantaneously returns, and at the same time, air is blown out from the pump air discharge hole 10 at once and loaded immediately before that. The ejected plastic bullet 15 is ejected.

In the case of continuous firing, if the single switching device 24 is set to continuous firing and the trigger 7 is kept pulled, the switch 8 remains closed, the motor 3 continues to operate, and the gear 65 keeps rotating. Spring 2 which expands and contracts by the floating shaft 5
3, the pump inner cylinder 4 repeats the reciprocating motion, and the compressed air is repeatedly ejected from the pump air discharge hole 10, so that the magazine 1
Plastic bullets 15 sequentially sent out from No. 3 are continuously ejected to perform continuous operation.

In the above-described switching of single-shot firing operation, the drive circuit of the motor 3 is controlled by a mechanical mechanism instead of the electronic control circuit.

As shown in FIG. 16, when the switch 8 is turned on, in the case of a single shot, the switch 8 momentarily closes the circuit of the motor 3, so that the motor 3 starts to rotate, and together with the circumferential cam 66, the switch instantly switches. 71 is pushed and connected, and the circuit is continuously connected for the length of the circumferential cam 66. When this is completed, the circuit is removed and the motor 3 is stopped.

However, the set point of the switch 71 needs to be determined in consideration of the inertia of the motor 3, and is considered to be a position slightly before the maximum compression point of the spring 23.
The length of 6 is also short, and it seems that about half of the circumference is sufficient.

When the rotation of the motor 3 is turned off by the switch 71, the switch 8 is instantaneously opened by the single switching device 24, and the motor 3 is stopped by a single operation.

On the other hand, if the single switching device 24 is continuously activated and the trigger 7 is kept pulled, the circumferential cam 66 of the gear 65 is
Even if the drive circuit of the motor 3 is cut off by the
Is locked by the control pin 31 of the single switching device 24 and keeps pressing the switch 8, so that the drive circuit of the motor 3 is held and continues to rotate, so that the trigger 7 is released at an appropriate time. The switch 8 is opened, and the motor 3 is stopped and the continuous operation is stopped after waiting for the switch 71 which is repeatedly opened and closed with the rotation of the circumferential cam 66 to be opened.

In this way, the crank system is used to convert the rotational motion into the sliding motion, and the drive circuit of the motor 3 is controlled to carry out the single-shot firing operation. In the direction of increasing or decreasing the stress of the stress source, the floating shaft 5
As the method of sliding the
As shown in FIG. 7, it is naturally conceivable that, for example, the floating shaft 5 and a gear of several stages are used.

That is, a rack 5a, which is a slider, is attached to the pump inner cylinder 4 that piston-operates as a displacement slider 9 that slides in the air pump chamber 1, and the rack 5a meshes with the gear 65 and slides to indirectly. 23 which is a stress source
Rack 5 which is a floating shaft in the direction of increasing or decreasing the stress of
a is slid.

More specifically, several stages of gears mesh with a gear that is rotated by the driving torque of the motor 3, and the rack 5a meshes with a gear 65 that meshes at the final stage.

On the other hand, the piston-operated inner cylinder 4 of the pump is constantly pressed by the spring 23 in the direction in which the air in the air pump chamber 1 is compressed so as to fire the bullet. Then, when the trigger 7 is pulled, the switch 8 is turned on, the motor 3 is rotated by the drive circuit of the motor 3 by the mechanical mechanism as shown in FIG. 17, and the pump inner cylinder 4 that piston-operates is moved by the elastic force of the spring 23. , Is instantaneously slid in the direction of compressing the air in the air pump chamber 1, and the compressed air is released to fire a bullet. In this case, when the motor 3 is stopped, the motor 3 is allowed to idle, and the motor drive circuit may be mechanical or electrical. However, in this case, it is desirable to provide a stopper for stopping the instantaneous movement in the compression direction of the pump inner cylinder 4 that operates the piston at an appropriate position. This stopper operates the electric circuit, and therefore an electric switch is used. The switch 18 shown in FIG. 17 fulfills its function.
This switch 18 is very important for rotating the motor 3 in the forward or reverse direction or idling to operate the piston of the pump inner cylinder 4 at an accurate position.

The electrical operation including the function of the switch 18 will be described in detail with reference to the electric circuit diagram shown in FIG.

Now, when the trigger 7 is pulled, the trigger crank 26 momentarily opens and closes the switch 8 if the single switching device 24 described above is set to a single shot. At this time, what is important is that, as shown in FIG. 17, the switch 8 and the switch 22 are connected in series, and the switch 71 is connected in parallel to these two switches. The opening and closing of the switch 8 remains open for only a moment until the circumferential cam 66 of the gear 65 pushes the switch 71 to hold the motor drive circuit,
When the circuit is closed together with the trigger operation, the switch 22 that has entered in series is pushed and connected at the front end of the rack 5a, so that the drive circuit is completed and the motor 3 starts to rotate, but at the same time, the pump inner cylinder 4 advances the rack 5a. With spring 2
3 is pushed forward while pushing 3, so that the switch 22 is released from the front end of the rack 5a where the switch was pushed, and the circuit is opened.

Therefore, the switch 71 must be connected before the switch 22 is turned off.

When the pump inner cylinder 4 advances until the compressive stress of the spring 23 reaches the required magnitude by the rotation of the motor 3, the circumferential cam 66 of the gear 65 ends and the switch 71 disengaged therefrom opens.

With this, the drive circuit of the motor 3 is completely cut off. Immediately thereafter, the switch 5 is pushed by the forward rack 5a, the terminal electrode of the motor 3 is reversed, and the motor 3 is reversed. Trying to start spinning.

However, since the rack 5a immediately shifts to the return movement, the switch 18 is immediately opened, and the reverse rotation time is extremely short,
The motor 3 is in a stopped state rather than reversely rotated, and the repulsive force of the compressed spring 23 causes the motor 3 and the gear group to idle and return the pump inner cylinder 4 to the original position. This is the stopper action of the switch 18,
At this time, in the case of a single shot, since the motor drive circuit is in the off state, the motor 3 is stopped by one rotation by the stopper action of the switch 18, and the gear operation also takes a single shot. If you put the single switching device 24 in a row,
The trigger 7 keeps pressing the switch 8 by the control pin 31, so that the circumferential cam 66 is pressed before the switch 22 is turned off.
The motor 3 continues to rotate by closing the switch 71, and when the switch 71 is disengaged from the circumferential cam 66, the motor drive circuit is opened, the switch 18 engages the stopper to lose the rotational force, and the spring 23 is repulsive. The process in which the pump inner cylinder 4 is returned, the switch 22 is turned on again by the rack 5a, and the motor drive circuit is completed together with the push-off switch 8 is repeated, the motor 3 continues to rotate, and the firing operation is also repeated. If the trigger 7 is released appropriately, the motor 3 is stopped and the continuous firing operation is completed by waiting for the end of the circumferential cam 66 and opening the switch 71.

As described above, the present invention can devise various firing mechanisms from the disclosed embodiments. From FIGS. 1 and 2, the injection of the plastic bullet 15 by the pumping action is described from FIGS. 3 and 4. Can inevitably analogize the method of using the displacement stress by using the spring 23 as a stress source. Furthermore, from FIG. 9, as a means for converting a rotary motion into a sliding motion, a gear group is used. It is also extremely easy to come up with all the piston methods.

Thus, a portable toy gun bullet electric launching device for single or continuous firing of plastic bullets according to the present invention,
Whichever the air pump chamber 1 or the spring 23 is used, the most significant effect is to give a huge gain of displacement on the screw shaft and a stress displacement in the axial direction at right angles to the center of the stress source regardless of the rotational moment of any motor. By the method of ideal force transmission, a strong stress source was formed, and by this stress, we succeeded in imparting 0.4 joules and super speed of 70 m / sec per second to the plastic bullet. , A simple conversion operation of continuous fire, in particular, a reliable operation with a simple mechanism by eliminating a complicated mechanism such as a clutch that does not require a large firing force unlike the conventional model machine gun In addition, it does not require complicated work such as gas cylinder conversion, compressed air injection, etc., all can be automatically operated, and it is completely affected by the temperature of air and springs. Not by energy source,
It makes it possible to use a toy gun's bullet firing effect all seasons, realizes the dream of using a toy gun in cold regions and winter, and in addition, it is very useful for preventing the pollution of CFC emission, which is ideal. As a projectile launching device for a toy gun, its numerous inventive benefits along with its novel invention principle give great benefits and progress in social and product aspects, and its value is truly immeasurable.

Claims (1)

[Claims] 1. A small toy gun that is fired in a single-shot or multiple-shot mode by a trigger operation by a control driven by an electric method and fixed by using a battery stored inside the toy gun body. Displacement is given to the pump inner cylinder as a displacement idler that fits into the pump outer cylinder and slides in an airtight manner by a floating shaft that is screwed directly by the rotational force of the motor or indirectly slides through a gear, A stress generating means such as a spring is set so that a stress is generated by the displacement of the pump inner cylinder, and the stress ejects air from the air discharge hole by the pumping action of the pump inner cylinder and the pump outer cylinder to eject the plastic bullet. When it reaches a size where it can be jetted with 0.4 joule of energy, the stress is instantaneously transmitted to the bullet by releasing the displacement and fired from the muzzle. In order to utilize the rotational force of the above in the direction of decreasing the stress of the stress generating means, when the floating shaft is slid again directly or indirectly via the gear, the driving of the floating shaft in the direction of increasing stress is performed. By making the rotational force of the motor ineffective, the pump inner cylinder as the displacement idler is returned to its original position, and it is also possible to repeat the motion of increasing and decreasing the stress. A portable electric toy gun bullet launcher that fires single or multiple shots of a characteristic plastic bullet.
