Description

  The present invention relates to a firing mode switching device in an electric air gun.

  A toy gun, commonly called an electric air gun, has a configuration in which a piston cylinder mechanism is electrically driven and a bullet is fired with compressed air generated by the advance of the piston. Prior art relating to this type of toy gun includes a series of ideas and inventions disclosed in Japanese Utility Model Laid-Open Nos. 3-104688, 3-104689, and Japanese Patent Laid-Open No. 3-221793. These are a motor-driven gear mechanism that retracts the piston via a rack provided on the piston side, accumulates a compression spring, and releases the piston when the gear in the gear mechanism is disengaged from the rack. A basic configuration of performing a compression process is disclosed.

  Although the above invention is epoch-making in the basic configuration and can be said to be unchanged at present, the bullet feeding mechanism has been improved, for example, as disclosed in registered utility model No. 3018271, the piston cylinder mechanism By retreating the whole, a space is created in front of the nozzle at the front end of the cylinder, and bullets are supplied there. However, switching between single shot and continuous shot is not perfect in terms of the form and arrangement of the parts with the above-described invention and invention, and there is room for improvement.

  The present invention has been made paying attention to the above points, and an object thereof is to provide a firing mode switching device in an electric air gun having a rational and simple configuration and capable of obtaining a smooth operation. Another object of the present invention is to provide a firing mode switching device in an electric air gun that can be made extremely compact.

  In order to solve the above problems, the present invention provides a piston cylinder mechanism that generates compressed air for firing a bullet, a gear mechanism that operates the piston cylinder mechanism, an electric motor that operates the gear mechanism, and an electric air gun having a switch thereof. A switching member for the firing mode which takes different positions by external operation is provided between the piston cylinder mechanism and the switch switching system of the motor, and the switching member is engaged with the piston in the operation stroke of the piston cylinder mechanism, and the switch of the motor A means for enabling selection between a single-shot mode in which the motor is turned off and a continuous mode in which the switch of the motor is turned on while pulling the trigger by taking a position not related to the operation of the piston-cylinder mechanism is provided.

  In the above configuration, the basic configuration including the piston cylinder mechanism, the gear mechanism, the electric motor, and the switch thereof may be common to the conventional one. The piston / cylinder mechanism may have an operational relationship with the bullet supply system in loading the next bullet into the loading unit by moving backward in connection with the piston retracting. The gear mechanism includes a meshing counterpart provided on the piston cylinder mechanism side, and a reduction gear set that takes out the rotational output of the electric motor in a usable form. The conventional configuration in which the pinion of the final gear of the reduction gear set and the rack on the piston side mesh with each other to retract the piston can be followed in the present invention.

  The switch of the electric motor is interlocked with the trigger operation. When the trigger is pulled, the switch is turned on (on), and when it is released, the switch is turned off (cut). In the present invention, the single-shot mode means an operation mode in which a single firing operation is performed each time the trigger is pulled, and the firing operation is not repeated even if the trigger is continuously pulled. The continuous mode means an operation mode in which the firing operation is repeatedly performed while the trigger is continuously pulled.

  The switching member is disposed between the piston cylinder mechanism and the switch of the electric motor, and operates in connection with the operation of the piston cylinder mechanism, and the operation switches the switch of the electric motor. The switch is turned off by this switching, and the switch is turned on again by the next trigger operation. That is, the single mode in which the operation is stopped for each launch operation is performed via the switching member. On the other hand, when the switching member does not function, the firing mode is repeated in which the firing operation is repeated as long as the trigger is continuously pulled.

  In order to select either the single mode or the continuous mode, the position of the switching member is switched. That is, the switching member is switched by an external operation and takes a different position. This external operation is performed, for example, through parts such as a switching lever and a button attached to the outside of the gun body, and the mechanism and structure for this can be arbitrarily selected.

  The switching member is provided so that one end thereof is positioned in the movement path of the piston and under biasing in the engagement direction with the piston, and resists the biasing force when engaged by retreating the piston. It is provided so as to be movable in the direction of movement. When the moving path of the piston is the front-rear direction, the moving direction of the switching member is the vertical direction, an engaging portion having an inclined surface is provided at the intersection, and the switching member can be moved using the component of the inclined surface as the moving force. .

  Since the present invention has the above-described configuration and operates, the piston-cylinder mechanism and the motor switch are connected by the switching member, and the single-shot mode and the continuous mode are selected by selecting whether or not to make this switching member function. Since the mode can be switched, the operation is smooth and reliable. Since the switching mechanism is combined with the piston / cylinder mechanism, the gear mechanism, the electric motor, and the switch thereof, the entire apparatus is very compact.

  FIG. 1 illustrates an electric air gun 10 equipped with a firing mode switching device 11 according to the present invention, wherein 12 is a gun body, 13 is a piston cylinder mechanism, 14 is a gear mechanism, 15 is an electric motor, and 16 is a switch thereof. Show.

  As shown in detail in FIG. 2 and subsequent figures, the piston cylinder mechanism 13 has a cylinder 21 slidably set on a cylinder slide portion 20, and the cylinder 21 has a nozzle 22 at the tip. The piston 23 is slidably incorporated in the cylinder and is urged in the compression direction by a compression spring 24. The piston 23 has a rack portion 25 at a lower portion, and a locking counterpart 26 that can be locked with a sector gear locking portion 28 described later is provided at the lower portion of the cylinder 21. Reference numeral 27 denotes a cylinder return spring.

The gear mechanism 14 has a reduction gear set 30 composed of a required number of gears, the first gear 31 meshes with the pinion of the electric motor 15, and the pinion sector gear 33 coaxial with the final gear 32 meshes with the rack portion 25. Is possible. The pinion sector gear 33 has a tooth portion having the number of teeth for retreating the piston 23 by one rotation and a toothless portion 34 that does not mesh with the rack portion 25. The device parts including the piston / cylinder mechanism 13, the reduction gear set 30, the electric motor 15 and the switch 16 are assembled to the main body base 19 and handled as a unit.

A switching member 35 is incorporated in the main body base 19 so as to be movable up and down between the electric motor 15 and the reduction gear set 30. One end portion 36 of the switching member 35 is located on the moving path of the engaging portion having the inclined surface 37 provided on the lower rear side of the piston 23. The inclined surface 37 has a cam function, and the switching member 35 can be pushed down by the component force of the inclined surface 37 when engaged. The other end 38 of the switching member 35 contacts an intermediate member 39 that connects the switch 16 and the trigger 40. The intermediate member 39 takes the state of FIG. 3 in which the switch 16 is switched by being pushed by the trigger 40 and the state of FIG. 9 in which the trigger operation is not applied to the switch 16 away from the switch. The intermediate member 39 and the trigger 40 constitute a switch switching system.

  The intermediate member 39 is pivotally supported by the base 19 and receives a force acting in a direction to return the trigger 40 and the switch 16 to a connected state. Further, the switch 16 receives the acting force of the return spring 41 and is turned on / off every time a sliding operation is performed from the intermediate member 39 side. The switching member 35 is provided so as to be in a position where it can move up and down, but not in contact with the intermediate member 39 that switches the switch 16 for the continuous mode. A power supply device for the electric motor 15 is built in the gun body 12.

  A bullet supply system 42 is connected to the bullet feeding section in which the nozzle 22 at the tip of the cylinder enters, so that a single spherical bullet 44 can be fed when the nozzle 22 is retracted. . 43 is a bullet portion in front of the nozzle, and when the cocking is completed, a spherical bullet 44 is arranged there.

  Next, the operation of the device 11 of the present invention will be described with reference to FIG. FIG. 2 shows a state in which the bullet supply system 42 is connected, the power is turned on, and the operation can be started anytime. At this time, the rack portion 25 and the pinion 33 of the final gear 32 can engage with the first teeth. Is at a critical stage. Further, the switching member 35 is pushed upward by the spring 45, and the one end 36 is located on the moving path below the piston.

<Single mode>
When the trigger 40 is pulled, the intermediate member 39 is pushed to the left in FIG. 3 and is turned on by pushing the switch 16 to the left to start the electric motor 15. As a result, the pinion (sector gear) 33 coaxial with the final gear 32 is engaged with the rack portion 25 via the reduction gear set 30, and the piston 23 starts to retract against the spring force of the compression spring 24 (FIG. 4). . When the piston 23 starts to move backward and a predetermined time elapses, the locking portion 28 of the sector gear 33 comes into contact with the cylinder side locking partner 26 (FIG. 5), and the cylinder 21 starts moving backward. As the cylinder 21 moves backward, one bullet is sent into the bullet feeding part in front of the nozzle (FIG. 6), and when the locking part 28 is released from the locking of the locking partner 26, the cylinder 21 moves forward and returns to the original position. The first bullet 44 is sent to the loading part 43 (FIG. 7).

  The inclined surface of the engaging portion of the piston 23 that continues to retreat even after bullet loading reaches the one end portion 36 of the switching member 35, and pushes the switching member 35 downward by the component force of the inclined surface 37 while retreating (FIG. 8). When the switching member 35 is lowered, the other end portion 38 pushes down the intermediate member 39, so that the force pushing the switch 16 disappears and the switch member 35 is turned off. At the same time, the last tooth of the sector gear 33 is connected to the rack portion 25. The meshing is released (FIG. 9). Therefore, the piston 23 is instantaneously advanced by receiving the total accumulated force of the compression spring 24 and can eject the bullet 44 by ejecting compressed air from the nozzle 22. Here, since the external force that has pushed down the switching member 35 disappears, when the trigger 40 is released, the intermediate member 39 becomes in a state where it can transmit the acting force again, becomes energized, and returns to the state of FIG.

<Sequential mode>
In the continuous mode, the switching lever (not shown) is operated to switch the one end portion 38 of the switching member 35 to a state where it is out of the movement path of the piston 23. In this switching by the lever, it is assumed that the other end of the switching member 35 is moved to a position where it does not contact the intermediate member 39 (FIG. 11). Therefore, when the trigger 40 is pulled, the electric motor 15 is started, and an operation for retracting the piston 23 is started. This is the same stage as FIG. 3 (FIG. 12). Thereafter, as the piston moves backward, the locking portion 28 of the sector gear 33 temporarily retracts the cylinder 21 (FIGS. 13 and 14), and the bullet 44 is fed from the bullet supply system 42 to the one-shot bullet portion (see FIG. 13). 15) Further, set in the loading section (FIG. 16).

  Even if the piston 23 moves to the retreat limit, since the switching member 35 is moved to a position where it does not contact in the continuous mode, the operation of the motor 15 in the energized state by the trigger operation is continuously performed (FIG. 17, FIG. 18). Then, when the sector gear 33 is disengaged from the mesh with the rack portion 25, the piston 23 is instantaneously advanced to generate compressed air, which is injected toward the bullet 44 (FIG. 19). In the continuous mode, since the motor 15 continues to operate while the trigger 40 is continuously pulled, the above-described operation is repeated as long as bullet supply continues, thus functioning as a continuous gun.
