Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a toy gun with a stable firing operation, which is an electric firing drive device which attempts to fire a plastic toy gun in a more stable state than a conventional large electric gun. So, in particular, a new mechanism was created so that it can be mounted even when trying to realize the electricization of small pistols in the future, in order to fire a plastic bullet,
By the rack gear of the left and right inner cylinder drive legs attached to face the bottom, or by fitting the inner wall drive projection attached to the movable lid and the passive projection built on the pump inner cylinder, By the left and right rack gears of the left and right movable lid drive legs that operate by inserting the left and right leg insertion grooves drilled in a part of the sliding groove that is cut into the side body and the sliding edge of the movable lid fits and slides, By engaging the left and right final drive gears and driving the left and right final drive gears by the rotational force of the motor, the spring mounted on the pump inner cylinder is displaced, and when the final displacement point is reached, the pump inner cylinder At the same time as mechanically or electrically controlling by the cylinder restraint mechanism, the final teeth of the left and right final drive gears are restrained, and at the same time the motor drive circuit is closed by an appropriate method to stop the motor and the left and right final drive gears are laterally locked. Ending the firing operation to release from its engagement with allowed toothless portion relative gear. If you want to manually perform rapid firing with the left and right final drive gears released from the meshing of the left and right rack gears, the movable lid was cut on the left and right sides by the same direction and distance as the left and right rack gears driven by the motor. When manually sliding along the left and right sliding edges, the inner wall drive projection of the movable lid presses the inner wall drive projection installed on the upper part of the pump inner cylinder, so that the pump inner cylinder resists the repulsive force of the spring. When the displacement is given, the pump inner cylinder retaining mechanism retains the pump inner cylinder at the final displacement point, and when the hand is released, the movable lid returns to the normal position before the operation by the movable lid return spring. Then, if necessary, pull the trigger to operate the pump inner cylinder restraint mechanism, and the pump inner cylinder is released from the restraint. Inject air to fire a loaded plastic bullet. At this time, the start changeover switch is turned off by any method, in this case, by causing an impact stroke, and the motor does not start operating. When you want to perform normal electric firing again, use an arbitrary method.Here, after returning the shock baffle to the original position and closing the start changeover switch, slide the movable lid manually to make the pump inner cylinder a pump inner cylinder restraint mechanism. If you pull the trigger after detaining, the inner cylinder of the pump will be released each time you pull the trigger.
The electric toy gun is also a stable launching device, which is equipped with a stable firing operation of the toy gun configured such that the toy gun is repeatedly detained and fires one plastic bullet each time the trigger operation is performed.

2. Description of the Related Art A conventional electric toy gun that ejects plastic bullets by air injection generated by the pumping action of a pump inner cylinder and a pump outer cylinder utilizing the displacement repulsive force of a spring driven by a gear driven by a motor is known. driving by the motor all is done by a single drive gear and the rack gear, will inevitably unstable because it is supported by one point of engagement of both the left and right, or also force the engagement point with or twisted or shake down Due to the concentration, the force applied to the drive gear and the rack gear becomes strong, and it causes a synergistic effect against runout and twist, so it is difficult to transmit the drive force from the motor in the correct form, and it is possible to wear or deform the gear early. This problem was serious, especially at the first and last teeth of the toothless portion of the drive gear. Also, because the reaction force of the powerful spring repulsive force makes it impossible to perform a stable firing operation, the conventional electric gun also begins to compress and displace the spring due to the inner cylinder of the pump when the trigger action occurs, and the powerful repulsion of the spring occurs. Due to the power, I could not support the electric gun, and it moved during the target aiming, so I could not aim accurately. In the case of conventional products, whether it is a large toy gun or a small pistol, a gas gun that uses CFCs, etc., controls the mechanism of applying gas pressure by mechanism or by time, and fires first. After that, there was a toy gun with a mechanism to prepare for the next strong reaction, but there was no electric toy gun at all. Furthermore, until now, electric guns have had problems of gear life, and have been limited to large ones that have sufficient space and can use large and thick parts. It has been considered almost impossible to use an electric mechanism for a complete small pistol, except for what is called an electric small pistol that is not completely electrified but seems to be an electric one. The development and manufacture of the optimized small handgun became possible along with the development of the electric gun firing stabilization mechanism, which was highly anticipated by the industry and users as well as the accuracy improvement by the accurate standard of plastic bullet shooting. .

[0003]

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, the electric firing drive device having the stable firing operation of the toy gun of the present invention is designed to cause the gear transmission mechanism to perform the firing operation in a stable state as much as possible. In order to reduce the wear and deformation of the gears at an early stage, the reaction of the firing operation by the strong repulsive force of the spring hinders stable firing operation, especially in the problem of electrification of small pistols. The instability of the target standard due to the reaction is particularly serious, and it is possible to make it possible with a stable electric firing drive device that the gun shakes a lot with each firing operation and accurate firing is almost impossible. Needed, and small pistols also have a special mechanism not found in large guns, making it difficult to solve these problems in a small space due to the huge complexity of the internal mechanism. Solution It was a big issue to carry out a single shot of a large electric gun, as well as one shot at a time, and one plastic bullet was fired stably at each trigger operation without being affected by the powerful repulsive force of the spring. The present invention is a firing drive device for an electric toy gun for firing a plastic bullet.

[0004]

SUMMARY OF THE INVENTION An electric firing drive device having a stable firing operation of a toy gun of the present invention transmits the driving force of a motor to the left and right final drive gears and directly through the left and right inner cylinder drive legs. Or the inner wall driving projection of the movable lid is fitted to the passive projection of the pump inner cylinder, and the left and right sliding edges of the movable lid are slid in the left and right sliding edges of the left and right side bodies while passing through the left and right leg insertion grooves. When the pump inner cylinder is displaced indirectly through the drive leg against the repulsive force of the spring and reaches the final displacement point, the pump inner cylinder is restrained by the pump inner cylinder restraint mechanism and at the same time, an appropriate method is used. The motor drive circuit is closed to stop the motor, and the inner cylinder of the pump is also locked. Next, when the trigger is pulled, the trigger acts on the pump inner cylinder restraint mechanism, so that the pump inner cylinder is released from the pump inner cylinder restraint mechanism. Air is ejected from the ejection port to eject the loaded plastic bullet. If you want to operate it manually, put the start switch in an arbitrary way here by inducing impact baffle and put the start changeover switch off so that the motor does not start operating again. At the end state of the firing operation, which is released from meshing in opposition to the toothless portion of the final drive gear,
When the movable lid is manually slid in the same direction and distance and with the same operation as the left and right rack gears driven by the motor, it displaces the inner cylinder of the pump with the same mechanism as when the movable lid is driven by the motor. It is locked by the pump inner cylinder locking mechanism at the displacement point. If you release your hand, the movable lid will return to the normal position before the operation by the movable lid return spring. Next, if necessary, pull the trigger.Each time the trigger is pulled, the release of the pump inner cylinder-manual movement of the lid-retention is repeated to fire the toy gun and continue firing one plastic bullet. With a stable and stable electric launch, it was possible to electrify a small handgun.

[0005]

[Operation] The electric firing drive device provided with the stable firing operation of the toy gun of the present invention can be operated manually or by a trigger with the left and right final drive gears being disengaged relative to the toothless portions of the left and right rack gears. When the movable lid is slid by the motor driven to start, the pump inner cylinder restraint mechanism or the final teeth of the left and right final drive gears displace the pump inner cylinder against the repulsive force of the spring until it is locked. , At the same time, the activation switch is opened.
When the trigger is pulled here, the trigger mechanically deviates from the pump inner cylinder by the pump inner cylinder restraint mechanism, and the pump inner cylinder is returned by the repulsive force of the spring to cause the pump outer cylinder and the pump outer cylinder to perform the pumping action. Air ejected from the air outlet of the cylinder fires a plastic bullet loaded in front of the air outlet from the muzzle, and at the same time when the firing operation ends, the start switch closes and the motor drive circuit is completed again and the motor And the left and right final drive gears mesh with each other to drive the left and right rack gears, and the left and right sliding edge of the movable lid smoothly fits into the left and right sliding grooves of the left and right side bodies via the left and right movable lid drive legs to move. The lid slides and its inner wall drive projections press the inner cylinder passive projections of the pump inner cylinder to transmit the driving force of the motor to the pump inner cylinder. Displacement of cylinder , Instead of the conventional drive only on the central axis of the pump inner cylinder, a pair of left and right transmission mechanisms are used for stable transmission of the driving force, and the pump inner cylinder continues to displace against the repulsive force of the spring. , At the final displacement point, the pump inner cylinder is locked by the pump inner cylinder locking mechanism, and at the same time, the motor stops when the motor drive circuit is turned off by any method, and the spring continues to stop while being compressed at the final displacement point. Prepare for the next firing operation. With this, the displacement of the pump inner cylinder due to the strong spring is completed before the next firing operation.If the trigger is pulled again in this state, the above operation is repeated, and the pump inner cylinder triggers the displacement and the release. Repeat each time you pull, firing the plastic bullet each time. At this time, the movable lid automatically returns to the localization value before the firing by the movable lid return spring mounted between the movable lid and the left and right side bodies each time the firing operation ends. It is necessary to be careful in this firing operation when the play game is over and the toy gun is no longer used, and when the firing operation is over, it is ready to launch, the spring is compressed and the pump inner cylinder is Since it is in a state of being restrained by the pump inner cylinder restraint mechanism, when the trigger is pulled, a plastic bullet is always fired, which is extremely dangerous. Therefore, at the end of the launch game, it causes an impact hit, or takes some measure to disconnect the motor drive circuit set by any method, and finally pulls the trigger once and shoots one shot. But I have to do it. At this time, if the stability of the firing operation is sacrificed, the pump inner cylinder is immediately moved along with the deviation of the left and right rack gears from the final teeth of the left and right final drive gears without causing a restraining action at the final displacement point of the pump inner cylinder. Even if it is returned, it is possible to perform the firing action by the pump action.In this case, the movable lid has the inner wall drive projection of the movable lid pushed by the inner cylinder passive projection of the pump inner cylinder, Since it returns, it does not affect the operation without the movable lid return spring. When firing plastic bullets manually instead of by motor drive, the start changeover switch is turned off by any method, here by causing street stake, so the motor drive circuit is also opened and the left and right final drive gears are left and right racks. When the movable lid is released against the toothless portion of the gear, slide the movable lid manually against the repulsive force of the spring, and hold the pump inner cylinder with the pump inner cylinder retaining mechanism. And then pull the trigger,
The trigger operates at the trigger operating point of the rapid setting plate to mechanically cause the pump inner cylinder restraint mechanism to deviate from the pump inner cylinder, release the pump inner cylinder and restore it by the repulsive force of the spring, and It works as a pump together with the cylinder to inject air from the air outlet to expel plastic bullets vigorously. In this way, firing-pump inner cylinder displacement (spring compression) -pump inner cylinder restraint is repeated, and the initial action for launch preparation is to move from the first stop position by pulling the trigger in the case of motor drive or manually in the case of manual operation. A small pistol that slides the lid to displace the inner cylinder of the pump to the final point where it is locked, then pulls the impact baffle and returns the impact baffle to the original one shot is impossible with one shot. It can also have unique functions. Moreover, such a manual device also has an advantage that, even if the electric toy gun becomes inoperable due to exhaustion of the battery, it is possible to continue firing manually for the time being. Furthermore, by driving the left and right final drive gears that mesh with the left and right rack gears attached to the inner cylinder drive leg portion that is installed in the pump inner cylinder with a motor,
The present invention for performing the firing operation of the inner cylinder of the pump against the repulsive force of the spring. The drive mechanism of the firing drive device of the electric toy gun for firing the plastik bullet, the firing operation does not use the movable lid, and the inner cylinder drive leg portion. It is exactly the same except that it directly drives the inner cylinder of the pump. Further, when a movable lid is attached to this mechanism, when the pump inner cylinder is driven by the left and right final drive gears via the right and left inner cylinder drive legs,
Contrary to when the movable lid is driven indirectly, the inner cylinder passive projection of the pump inner cylinder pushes the inner wall drive projection of the movable lid and is locked by the locking mechanism at the final displacement point in the pump inner cylinder. When the inner cylinder of the pump is locked, the movable lid is independently returned by the repulsive force of the movable lid return spring. It should be noted that, instead of a pair of left and right motor driving force transmission mechanisms such as left and right final drive gears and left and right rack gears, a single final drive gear or a single rack gear is already used for a large transmission toy gun. , It is lacking in stable operation, but there is a difficulty in practical use, but it can be used for electrification of the model pistol, so I will touch it here.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The electric launch drive device having a stable firing operation of the toy gun of the present invention can be used for both a large toy gun and a small pistol in the same manner, but as an example, only a small pistol will be described. To do. A firing drive device for an electric toy gun for firing a plastic bullet according to the present invention will be described in detail with reference to the drawings. First, the mechanism will be described from a small pistol using the movable lid (1). As shown in the drawing, set the inner wall of the movable lid (1) by sliding the movable lid (1) manually to the rear or by inserting the trigger switch (47) to operate the motor drive circuit. The driven inner wall driving projection (2) presses the inner cylinder passive projection (4) provided at the upper rear end of the pump inner cylinder (3) to resist the repulsive force of the spring (5) and the pump inner cylinder. (3) is displaced rearward, and when the spring (5) reaches the final displacement point at which it reaches the stress at which sufficient energy has been stored for firing the plastic bullet (6), the pump inner cylinder (3) causes the pump inner cylinder restraint mechanism. To be detained. This pump inner cylinder restraint mechanism is a mechanism or shape for transmitting an operating force through an intermediary between an operating point (power point) and a pump inner cylinder restraint point, or a method or position for restraining the pump inner cylinder (3). Since there are several possible combinations in terms of shape, etc., only one embodiment of the present specification and drawings will be given as a representative. As shown in the drawings, in the pump inner cylinder restraining mechanism of the embodiment, the pump inner cylinder (3) displaced to the final displacement point is
While pushing down the locking restraint (9) of the rapid-fire setting plate (8) by the restraining tongue (7) set at the lower part, the spring is inserted and restrained, and the pump inner cylinder (3) is displaced. To end. Next, when the trigger (10) is pulled to fire the plastic bullet (6), the pressing protrusion (12) of the trigger (10) loosely attached at the rotation center point (11) causes the rapid-fire setting plate (8). While pushing up the trigger operating point (13) of the, it rotates about the operating center point (14), and the other end of the locking engagement (9).
Is pushed down to release the pump inner cylinder (3) from the lock of the locking lock (9). The rapid firing setting plate (8) is disengaged at the same time as the trigger operating point (13) deviates from the pressing protrusion (12) of the trigger (10) from the retaining lock (9) of the pump inner cylinder (3). Return to the original state and prepare for the next restraint of the pump inner cylinder (3). At this time, the pump inner cylinder (3) vigorously returns due to the repulsive force of the spring (5), performs a pumping action together with the pump outer cylinder (15), and ejects air from the air discharge port (16) thereof. The plastic bullets (6) loaded in the are ejected from the muzzle (17). The pump inner cylinder (3) that has finished firing the plastic bullet (6) returns to the original position and at the same time, the start switch (18) is pressed to start the motor drive circuit,
The motor (20) starts to rotate by the battery (45) and moves from the worm gear (21) to the worm gear (22).
A pair of left and right final drive gears (23, 23 ') via
To drive. As a result, the left and right final drive gears (23, 2,
The left and right rack gears (24, 24 ') meshing with 3') are driven, shaped so as to support the left and right rack gears (24, 24 '), and left and right provided on the left and right side bodies (25, 25'). The left and right movable lid drive legs (28, 28 ') that slide by being inserted into the left and right leg insertion grooves (27, 27') formed in a part of the sliding grooves (26, 26 ') are movable lids (1). ) By the left and right sliding edges (53, 53 ').
Slide smoothly in 3 '). Then, the inner wall drive projection (2) set on the inner wall of the movable lid (1) pushes down the pump inner cylinder (3) while pressing the inner cylinder passive projection (4), and the spring (5) is required. At the final displacement point where the stress is reached, the rapid-fire setting plate (8) is locked by the locking lock (9) and stopped. At this time, the left and right final drive gears (23, 23 ')
Immediately after the actuating projections (29) are attached to either of the left and right sides of the pump inner cylinder (3) at the final displacement point, the control switch (30) is turned off to open the motor drive circuit (19).
Stop the motor (20). There are various possible ways to turn off the motor drive circuit (19). In this embodiment, the control switch (30) is used. However, the timer IC generates one firing time to control the transistor. It is also possible to consider a method of performing it, and several other types of circuits are possible, and it is for that reason that the motor drive circuit (19) is cut off by an arbitrary method in the scope of the patent. This is the end of the firing operation, but the electric toy gun is held in standby for the next firing operation with the pump inner cylinder (3) being locked and the spring (5) being compressed. By the way, at this time, the control switch (18) turns on the pump inner cylinder (3).
Since it is operating immediately after the restraint of the vehicle is completed, its operating point is after the final displacement point in terms of time, and the left and right final drive gears (23, 23 ') are the left and right rack gears (24, 24 ') has been driven and the toothless portion of the movable lid (1) has been disengaged from each other.
Is in a free floating state, and the movable lid return spring (3
By 4), it has returned to the localization value before the firing operation. At this time, if the stability of the firing operation is sacrificed, from the final teeth (52) of the left and right final drive gears (23, 23 ') without causing the restraining action at the final displacement point of the pump inner cylinder (3). Even if the left and right rack gears (24, 24 ') are deviated and the pump inner cylinder (3) is immediately returned, it is possible to perform the firing action by the pump action. In this case, the movable lid (1) is the spring ( When the inner wall driving projection (2) of the movable lid (1) is pushed by the inner cylinder passive projection (4) of the pump inner cylinder (3) by the repulsive force of 5), the movable lid return spring (34) returns to its original position.
The need for is gone. The force method for restraining the inner cylinder (3) of the pump at the final displacement point can also be performed by electric control, which will be described with reference to the drawings. As in the motor drive circuit shown in the figure, in this case, the pump inner cylinder (3) is now the left and right rack gears (24, 24 ') by the final teeth (52) of the left and right final drive gears (23, 23'). It is in custody, and by pulling the trigger, the trigger switch (47)
Is pressed, the motor drive circuit (19) is activated, the left and right final drive gears (23, 23 ') are driven, and the left and right rack gears (24, 24') are released from the retention of the final teeth (52). Then, the pump inner cylinder (3) performs a firing operation by the repulsive force of the spring (5). At the same time, the left and right final drive gears (2
(3, 23 ') has deviated from the control switch (30), so it continues to rotate, and after the firing operation is completed, the left and right rack gears (24, 24') of the pump inner cylinder (3) at the localization value are located.
The first inner tooth of the gear is caught and meshed, and the inner cylinder (3) of the pump is displaced while compressing the spring (5) again to reach just before the final tooth (52) of the left and right final drive gears (23, 23 '). Then, the control switch (30) is activated and the motor (2
0) stopped rotating and left and right final drive gears (23, 2)
3 ') rotates one or two gears due to inertia (just stopped at this final tooth (52) and stopped. The timing at which this final tooth (52) is locked and stopped is the position of the control switch (30). When the trigger (10) is pulled in the next firing operation of the pump inner cylinder (3) thus restrained, the motor drive circuit (19) is activated again and each firing operation is performed. In this way, when the pump inner cylinder restraint mechanism is used, trigger operation-plastic bullet firing-start switch ON-motor rotation-pump inner cylinder displacement-spring compression-pump inner cylinder restraint. -Repeating the motor stop repeatedly, the left and right final drive gears (2
(3, 23 ') is locked by the final tooth, the trigger operation, the trigger switch operation, the motor start, the pump inner cylinder release, the firing operation, the pump inner cylinder displacement, the spring compression, and the pump inner cylinder restraint are repeated. The firing operation is continued until the plastic bullets (6) in the magazine (31) are exhausted one by one. Next, when it is desired to take a rapid-fire attitude, the impact baffle (32) is applied while the final left and right drive gears (23, 23 ') deviate from the mesh with the left and right rack gears (24, 24'). When it is caused, the start changeover switch (33) is turned off, and the motor drive circuit (1
Since 9) is not completed, it can no longer be driven by the motor. When the movable lid (1) is slid manually, the pump inner cylinder (3) is operated in exactly the same procedure as the first firing preparation operation of electric drive.
Is detained. When you want to fire, pulling the trigger (10) releases the pump inner cylinder (3), and the plastic bullet (6) is fired by the pump action, but at this time, the motor drive circuit (19) Since it is open, the motor (20) does not work, and when you want to fire again, the movable lid (1)
Is manually slid to lock the pump inner cylinder (3). This mechanism is convenient because the firing can be continued manually when the battery runs out while the electric gun is in use. Moreover, the mechanism for pulling the impact stick (33) to take rapid fire is also attached to the real gun. It resembles a thing and enhances the power of a toy gun. Further, the movable lid stopper (35) is also attached to the outside of the left and right side bodies (25, 25 ') in order to resemble a real gun, and constitutes a part of the start changeover switch (33). , When not firing, raise the movable lid stopper locking end (37) to lock the movable lid (1) in the normal position in the movable lid notch groove (36), and at the same time, start switch (33) The motor drive circuit (19) is also turned off by the movable lid stopper switch (51) of the motor (1
0) does not start absolute rotation. If the magazine (31) is touched and the battery (21) is now pulled out from the handle of the gun, the magazine (31) integrated with it will also come out. Here, the compression spring (39) is used to compress and set the magazine spring (38) to the full position with the notch stopper (40) until it stops, and the plastic bullet (6) is packed to the entrance (about 10 shots). . After that, the magazine (3
1) is inserted until it coincides with the ballistic fitting opening (43) at its tip, and the compression knob (39) is removed from the cutout stopper with a thin object from the outside, and the plastic spring (38) remains compressed. By pressing 6), this pressure also extends to the magazine trajectory (41) and the plastic bullet (6) that is clogged in the loading port (42), and the air is released from the pump outer cylinder ((15)) during the firing operation. As the outlet (16) retreats, the plastic bullets (6) are sent to the firing port (44) one by one and fired one by one by a firing operation. There are various feeding mechanisms of (6) to the launch port (44),
This embodiment is only a very rudimentary example, and although there are various methods, it is omitted because it is not the purpose of the patent. Next, it is not a small pistol that uses the movable lid (1), but an outer shape is integrated and the firing drive mechanism is stored, so that the operation of the small pistol cannot be seen from the outside. An embodiment using a driving drive device for an electric toy gun that shoots bullets will be described. As shown in FIGS. 3 and 4, in the movable lid system, the left and right rack gears (24, 24 ′) are set to the left and right movable lid drive leg portions (28, 2 ′) set on the movable lid (1).
8 '), but in the case of this mechanism, the left and right inner cylinder drive legs (46, 46') provided with the left and right rack gears (24, 24 ') are attached to the pump inner cylinder (3). Directly attached to the left and right rack gears (2
4, 24 ') meshes with the left and right final drive gears (23, 23') as in the case of the movable lid system, and the motor directly drives the pump inner cylinder (3), and its firing mechanism is The movable lid system is exactly the same as the movable lid system except that the manual operation of displacing the pump inner cylinder (3) by the movable lid and restraining it by the restraining mechanism to prepare for the firing is impossible. Furthermore, when attaching the movable lid (1) to this mechanism,
When the pump inner cylinder (3) is driven by the right and left final drive gears (23, 23 ') via the right and left inner cylinder drive legs (46) directly connected, the movable lid (1) is indirectly driven. Contrary to when it is operated, the inner cylinder passive projection (4) of the pump inner cylinder (3)
While pushing the inner wall drive projection (2) of the movable lid (1), the pump inner cylinder (3) is displaced until it is locked by the locking mechanism at the final displacement point, and the pump inner cylinder (3) is locked. Then, the movable lid (1) is independently returned by the repulsive force of the movable lid return spring (34). Further, as shown in the drawing, the left and right final drive gears (23, 23 '), the left and right rack gears (24, 2')
4 ') drives the pump inner cylinder (3) both in the case of the movable lid system and in the case of directly driving the pump inner cylinder by using a single final drive gear and a single rack gear instead. It is possible to drive exactly the same electric gun, and large electric toy guns are already manufactured and sold in general, but it is also possible to electrify small handguns by using a single final drive gear and rack gear. It will be possible, so put it here.
Here, the operation of the motor drive circuit that drives the motor will be described. However, it should be noted that this circuit is merely an example, and several types of circuits are conceivable as described above. As shown in the figure, the motor drive circuit (19) operates the relay (48) to turn on the relay switch (49) to drive the motor (20). To get ready to fire first, pull the trigger and close the trigger switch (47).
A voltage is applied to the signal input of 9), the SCR used operates to drive the relay (48), and the relay contact (49)
Is closed and the motor (20) rotates. Simultaneously with the rotation, the left and right final drive gears (23, 23 ') retract the left and right rack gears (24, 24'), so that the start switch (18) opens and disconnects the signal circuit, but the SCR continues to operate. Then, immediately after the pump inner cylinder (3) is locked by the locking lock (9) of the rapid-fire setting plate (8) at its final displacement point, the control switch (30) is activated to operate the motor drive circuit (19).
Turn off the motor (20) to stop the preparation for firing. Then pull the trigger (10) if necessary,
The pump inner cylinder (3) is mechanically released from the restraint of the locking restraint and is instantly returned by the repulsive force of the spring (5) to activate the starter switch (18), and the trigger switch (in series) ( Since 47) is closed by the trigger operation, it functions as a signal input to the motor drive circuit (19), the SCR is operated, and the relay (48) rotates the motor (20) to rotate the pump inner cylinder (3). Displace and turn off the control switch (30) as described above at its final displacement point. During this time, one plastic bullet (6) is fired, and each time the trigger (10) is pulled, a single firing operation is repeated. When the impact baffle (32) is pulled and the rapid firing mode is set, the movable lid (1) is manually slid backward to hold the pump inner cylinder (3), and the trigger (10) is pulled. The detention is mechanically released, the pump inner cylinder (3) is restored, and the start switch (18) is pushed, but the impact switch (33) causes the impact change switch (33) to move.
Since 0) is cut off, the SCR does not start, so the firing operation ends, and the firing operation is repeated by pulling the movable lid (1) and repeating firing.

[0007]

Since the electric firing drive device having the stable firing operation of the toy gun of the present invention has the structure as described above, the firing drive is performed by the pair of left and right final drive gears and the left and right rack gears. By doing so, a huge amount of force is applied to the final drive gear and the rack gear in order to prepare for the firing operation against the strong repulsive force of the spring, and therefore, conventionally,
In the drive system that is supported only on the center axis of the pump inner cylinder, the final drive gear and rack gear are twisted or tilted and the meshing becomes unstable, and an extra load is applied to the motor and the pump inner cylinder tilts. The pump action is incomplete by inserting it into the outer cylinder of the pump, or idling due to premature wear or damage of the gears, especially the first and last teeth of the left and right final drive gears. Although there were various defects that could not be counted particularly violently, the present invention, which was supported at two positions on the left and right, has a fulcrum at the positions of two points, so that it can be stably driven without tilting or twisting, and an enormous spring Since the driving force that utilizes the repulsive force of is also divided into two points, it is possible to support it in a divided manner. Extended life of parts It contributes to the improvement of the quality of the toy gun, which in turn leads to a relative cost reduction of the product, and since the left and right final drive gears are separated into left and right, there is a space between them, Various parts can be incorporated, and it is possible to deal with the complicated mechanism due to the upsizing of toy guns, and it is especially effective for electrification of small pistols.

Claims (3)

(57) [Claims] 1. A head of an electric toy gun in an electric toy gun in which a motor displaces a spring through a gear and a repulsive force drives a pump action to eject a plastic bullet by jetting air. Part of the left and right sliding grooves is placed at an appropriate position on the left and right sliding edges on both sides of the movable lid that is fitted so as to cover the part and slide back and forth along the left and right sliding grooves of the left and right side bodies. The left and right movable lid drive legs that are set to operate while being fitted into the left and right leg insertion grooves, or the bottom of the pump inner cylinder that operates by being fitted into the pump outer cylinder to perform the pump action. By the left and right inner rack drive gears attached to the left and right inner cylinder drive legs,
It meshes with the left and right final drive gears driven by the motor, and the inner wall drive protrusions on the inner wall of the upper part of the movable lid interact with the passive protrusions installed on the upper part of the pump inner cylinder. By transmitting the driving force from the movable lid to the pump inner cylinder or vice versa, the pump inner cylinder fitted into the pump outer cylinder is displaced against the repulsive force of the spring and the spring reaches the required stress. At the same time when the final displacement point is reached, the left and right final drive gears deviate from the rack gears of the left and right inner cylinder drive legs at the toothless portions, and the pump inner cylinder returns due to the repulsive force of the spring and the pump outer cylinder and pump An electric firing drive device having a stable firing operation of a toy gun that operates. 2.
