Description

  The present invention relates to a reaction generator for a toy gun that allows a shooter to experience a relatively large reaction.

  Conventionally, an attempt has been made to cause a toy gun to produce a reaction similar to the reaction that occurs when using a real gun. For example, Patent Document 1 discloses a reaction (recoil) to a shooter when a bullet is fired. A toy gun equipped with a reaction generator configured to feel a shock) is described.

  In the reaction generator for a toy gun described in Patent Document 1, a cylinder having a piston slidable in the front-rear direction is disposed in the engine chamber of the gun body, and between the piston and the rear wall of the engine chamber. On the other hand, there is provided a weight working chamber in which a weight is slidable in the longitudinal direction on the moving axis of the piston behind the engine chamber. A recoil spring is interposed between the rear wall surface of the weight and the rear end surface of the weight, and a rod of a fixed length is projected from the center of the front end surface of the weight toward the front, and this rod is attached to the rear of the engine room. It has a structure in which it is slidably penetrated through the wall and its front end protrudes into the engine room so as to be able to contact the rear end surface of the piston.

  Furthermore, a rack is provided projecting rearward at the lower end of the piston, and a sector gear meshed with the rack is rotated through a meshing gear train by a motor that operates by pulling a trigger, After the piston is rapidly retracted while compressing the piston spring, the piston is quickly moved forward by the restoring force of the piston spring by releasing the meshing of the sector gear with the rack at the retracted end, and the air in the cylinder is compressed. While the bullet is fired by compressed air, the recoil spring pushes the weight backward through the rod and compresses the recoil spring, then the piston releases the pressure and the recoil spring pushes the weight forward and starts to expand. The reaction force is recoiled (recoil shock) so that the shooter can experience it. There.

  However, according to the reaction generator for a toy gun described above, the weight and recoil spring are arranged in series in the front and back in the weight working chamber provided behind the engine room. Increasing the length shortens the recoil spring length, while increasing the recoil spring length forces the weight length to be shortened, so the recoil spring extension amount and weight movement amount are limited within a narrow range. After the recoil spring is compressed, it becomes difficult to set the reaction force generated on the rear end surface of the weight working chamber to a sufficient magnitude as the weight moves when the recoil spring is expanded, and the reaction applied to the archer There was a problem that was relatively small.

  Further, as described above, since the amount of movement of the weight in the weight working chamber is limited to a narrow range, when the recoil spring is extended, there is a situation in which the front end of the weight abuts against the front end side of the weight working chamber. In addition to the possibility of damage to the operating mechanism and the like, there is a problem in that the impact force acts in the direction opposite to the reaction generating direction to give the shooter an uncomfortable feeling.

  The present invention has been made in view of such problems, and the object of the present invention is to set the amount of movement of the weight in the weight working chamber and the amount of compression and expansion of the recoil spring to be large. Another object of the present invention is to provide a reaction generator for a toy gun that allows a shooter to experience a sufficient reaction.

  In order to achieve the above object, a reaction generator for a toy gun according to the present invention comprises a cylinder in which a piston is slidably mounted in a longitudinal direction in an engine room of a gun body, and a piston forward. A piston spring that presses against the engine chamber, and a weight storage chamber is provided at the rear of the engine chamber, and a weight that moves backward with the piston when the piston retracts and the weight forward A recoil spring to be pressed, and the piston is retracted by a trigger operation and the weight is retracted integrally with the piston while compressing the recoil spring, and then the piston is moved to the piston spring. The recoil spring acts on the rear wall of the weight storage chamber when the recoil spring moves from compression to extension due to the restoring force. In the toy gun recoil generating device configured to generate movement, a space for storing the recoil spring is provided in the weight disposed in the weight storage chamber so as to be movable back and forth, and after the weight storage chamber. A fixed rod body that is long in the front-rear direction is protruded from the wall surface, and the fixed rod body is inserted into the insertion hole communicating with the space portion from the rear end of the weight. The front end surface of the rod body and the front end of the space portion The recoil spring is interposed between the surface and the surface.

  In the reaction generator for a toy gun configured as described above, the invention according to claim 2 is provided with a through hole communicating with the weight storage chamber in the rear wall of the engine chamber in the gun body, and the piston and the weight storage chamber. A transmission member for transmitting the retraction of the piston to the weight through the through hole is provided between the weight and the weight.

  According to a third aspect of the present invention, the front end of the transmission member is fixed to the central portion of the rear end of the piston, while the rear end has a small space forward from the front end surface so as to be able to contact the front end surface of the weight. It is characterized by being spaced apart.

  Further, in the invention according to claim 4, a short coil spring in which the rear end portion is inserted into the through hole when compressed is provided in the through hole provided in the rear wall of the engine room. A head having a smaller diameter than the through hole is provided at the front end of the weight, and the front end surface of the small diameter head is received by the rear end of the coil spring.

  According to a fifth aspect of the present invention, the transmission member comprises a small-diameter tube, a buffer spring is disposed in the front portion of the transmission member, and a small-diameter movable rod is disposed in the transmission member from the rear end of the transmission member. The small-diameter movable rod is inserted so that the front end of the small-diameter movable rod comes into contact with the rear end of the buffer spring and is detachably received, while the rear end of the small-diameter movable rod protruding rearward from the rear end of the transmission member It connects with the front-end part of this.

  According to the first aspect of the present invention, the weight is stored in the weight storage chamber disposed behind the engine chamber in the gun body so as to be movable back and forth, and the space portion in which the recoil spring is disposed in the weight is provided. A rod body that is long in the front-rear direction is provided on the rear wall of the weight storage chamber, and the rod body is inserted into an insertion hole that is provided so as to communicate with the space from the rear end of the weight. Since the recoil spring is interposed between the front end surface of the lever body and the front end surface of the space portion, the recoil spring is disposed inside the weight. And the length of the recoil spring can be set to be as long as possible to increase the amount of compression and extension, and therefore the piston in the engine chamber can be moved rearward. When the recoil spring is compressed while pushing the weight backward, the reaction force due to the recoil spring transmitted to the rear wall surface of the weight storage chamber is increased with the movement of the weight when the pressure by the piston is released. This reaction force allows the shooter to experience a large reaction (recoil shock).

  Furthermore, even if the recoil spring is extended, a space is provided between the front end surface of the weight and the rear wall of the engine room so that the weight can further advance, so that the front end of the weight is on the front end side of the weight storage chamber. It is possible to prevent a situation such as a collision.

  According to the second aspect of the invention, the rear wall of the engine chamber in the gun body is provided with a through hole communicating with the weight storage chamber, and the piston is retracted between the piston and the weight in the weight storage chamber. Since the transmission member that transmits to the weight through the through hole is provided, the operation of the piston can be reliably and accurately transmitted to the weight via this transmission member.

In addition, according to the invention of claim 3, the front end of the transmission member is fixed to the central portion of the rear end of the piston, while the rear end is brought forward from the front end surface so as to be able to contact the front end surface of the weight. Since the piston is separated by a small interval, when the piston moves backward, the spring that presses the piston forward is compressed and the backward movement is transmitted to the weight via the transmission member to ensure the piston and the weight. On the other hand, when the piston reaches the retracted end at an accelerated speed, the weight is instantaneously separated from the rear end surface of the transmission member by the inertial force and impacted on the rear end surface of the weight storage chamber. So that the archer can experience a greater reaction and the piston is advanced forward by the restoring force of the spring. And smoothly to stretch the recoil spring without impinging weight to the transmitting member can be effectively generating the recoil.
Can be generated automatically. )

  According to the invention of claim 4, the short coil spring whose rear end portion is inserted into the through hole when compressed is provided in the through hole provided in the rear wall of the engine room. Since the front end of the weight is provided with a head having a smaller diameter than the through hole and the front end surface of the small diameter head is received by the rear end of the coil spring, the recoil spring is compressed and expanded. When the weight is extended back to the maximum when it is pushed back, the front end surface of the weight is brought into contact with the protruding end of the coil spring provided in the through hole. The weight can be returned to the original position while decelerating, and the front end face of the weight can be reliably prevented from colliding with the rear wall of the engine room, and the operating mechanism and the like in the rear wall and the engine room are damaged. Can prevent .

  According to a fifth aspect of the present invention, the transmission member comprises a small-diameter tube, a buffer spring is disposed in the front portion of the transmission member, and a small-diameter movable rod is disposed in the transmission member from the rear end of the transmission member. The small-diameter movable rod is inserted so that the front end of the small-diameter movable rod comes into contact with the rear end of the buffer spring and is detachably received, while the rear end of the small-diameter movable rod protruding rearward from the rear end of the transmission member is weighted. When the piston moves backward while compressing the piston spring, the small-diameter movable rod in the transmission member is first pushed backward while compressing the buffer spring, and the weight starts to retract. Immediately after applying the initial speed, the rear end of the transmission member can be brought into contact with the weight so that the weight can be smoothly retracted, and the weight generates a recoil via the recoil spring. When the pushed the small diameter movable rod forward rebounding while the impact force to the piston absorbs the pressing force by the buffer spring it can be prevented from being transmitted.

A firing means is provided. As shown in FIG. 1, this bullet firing means has a rack 24 projecting rearward from the lower end portion of the piston 4 housed in the cylinder 3, and a sector gear 25 is engaged with the rack 24. By rotating the sector gear 25, the piston 4 provided with the rack 24 is retracted while compressing the piston elastic spring 16, and when the non-toothed portion of the sector gear 25 comes into contact with the rack 24, the meshing is released and the piston 4 is The bullet 23 is fired by quickly moving forward while compressing the air in the cylinder 3 by the restoring force of the piston bullet spring 16.

  The sector gear 25 is rotated via a meshing gear train 27 driven by a motor 26. The motor 26 is operated by a switch that is switched by pulling a trigger 20, and can be switched between single firing and continuous firing. I have to.

  Next, the action of the recoil generating device in the toy gun configured as described above will be described. Prior to the use of this toy gun, the piston 4 is located in the front part of the cylinder 3 by the piston spring 16 and, as shown in FIG. The rear end faces the front end opening of the through hole 13 provided in the rear wall 2a of the engine room 2, and the small-diameter movable rod 19 disposed in the transmission member 14 has its front end connected to the transmission member. The rear end of the shock absorber spring 18 disposed in the front portion of 14 is pressed into contact with the rear end of the transmission member 14 from the rear end of the transmission member 14 into the weight storage chamber 5 behind the engine chamber 2. The cylindrical member 12 provided in the weight 6 is brought into contact with the front end.

  Further, the sector gear 25 meshes with the rear end portion of the rack 24, while in the weight storage chamber 5 behind the engine chamber 2, the weight 6 is pressed forward by the recoil spring 10 and the small-diameter head 6 a The front end surface is received by the rear end of the short coil spring 17 protruding from the inside of the hole 13.

  When the trigger 20 is pulled from this state to drive the motor 26 and rotate the sector gear 25 via the meshing gear train 27, the piston 4 having the rack 24 meshed with the sector gear 25 is moved to the piston spring 16. Retreats rapidly while compressing. In the initial stage of the retraction of the piston 4, first, the transmission member 14 is disposed in the front portion of the transmission member 14 while the transmission member 14 moves backward until the rear end thereof contacts the small-diameter head 6 a of the weight 6. The buffer spring 18 is compressed and the compression force is transmitted to the weight 6 via the small-diameter movable rod 19 to push the weight 6 slightly backward, and then the rear end of the transmission member 14 contacts the tip member 6a of the weight 6. As shown in FIG. 3, the weight 6 retreats integrally with the piston 4 through the transmission member 14 while compressing the recoil spring 10.

  The recoil spring 10 is disposed in the weight 6, and a guide rod 9 in which a fixed rod body 8 projecting forward from a stock end 7 at the rear end of the weight storage chamber 5 is provided at the center of the weight 6. Since the recoil spring 10 is received at the tip end of the weight 6, the weight 6 can be retracted to a position where the rear end face is close to the stock end 7 while the recoil spring 10 is compressed in the weight 6. The amount of compression of the recoil spring 10 can be increased to generate a large resilience.

  The piston 4 starts to move backward and the weight 6 moves backward to the vicinity of the stock end 7 instantaneously. The compression force of the recoil spring 10 due to the backward movement of the weight 6 is stored through the fixed rod body 8. When the weight 6 is transmitted to the end 7 and moves to the backward end as shown in FIG. 4, the sector gear 25 is disengaged from the rack 24, and the piston 4 is moved by the restoring force of the piston spring 16. 5, the recoil spring 10 is compressed by the advance of the piston 4, and the recoil spring 10 is turned to the extension by the restoring force following the advance of the piston 4, and the weight 6 is moved. Pushing forward, the rebound acting force when restoring from the compression of the recoil spring 10 is transmitted as a reaction force to the stock end 7 via the fixed rod body 8. Can the reaction force to feel the shooter as a reaction (recoil shock).

  Further, when the piston 4 rapidly moves rearward and then turns forward, the weight 6 is momentarily further retracted by the inertial force, and the rear end surface collides with the stock end 7 to cause a recoil shock (recoil shock). It is possible to cause the shooter to experience a large reaction as well as the reaction caused by the recoil spring 10. The weight 6 can be made to collide with the stock end 7 directly by inertial force because the sum of the length of the weight 6 and the length of the recoil spring 10 is the length of the weight storage chamber 5 as described above. In the present invention, even if the sum of the length of the weight 6 and the length of the recoil spring 10 is made shorter than the length of the weight storage chamber 5, the recoil spring 10 causes the reaction. Can be generated.

  As described above, when the weight 6 turns forward by the restoring force of the recoil spring 10 following the piston 4 while generating a recoil, and the small-diameter head 6a reaches near the rear surface 2a of the rear wall 2a of the engine room 2. The front end of the small-diameter movable rod 19 projecting forward from the small-diameter head 6a abuts the rear end of the buffer spring 18 disposed in the front portion of the transmission member 14, as shown in FIG. The buffer spring 18 is compressed, and the front end surface of the small-diameter head 6a abuts against the rear end of the coil spring 17 protruding rearward from the inside of the through hole 13 to compress the coil spring 17. The forward movement force of the weight 6 is absorbed by the compression of the weight 18 and the coil spring 17 to brake the forward speed, and the front end surface of the weight 6 is not brought into contact with the rear wall 2a of the engine room 2 and the tip of the small-diameter head 6a. With the part immersed in the through-hole 13 Stop moving forward.

  In this manner, the weight 6 can be moved forward by the restoring force of the recoil spring 10 until the tip of the small-diameter head 6a is immersed in the through hole 13, so that the recoil caused by the recoil spring 10 can be increased. .

  Further, immediately after the weight 6 compresses the coil spring 17 and the forward end of the small-diameter head 6a is inserted into the through hole 13 and stops moving forward, the weight 6 causes the recoil spring 10 to move by the restoring force of the coil spring 17. As shown in FIG. 7, it is pushed back while being compressed, and the rearward movement of the weight 6 is transmitted as a slow reaction force from the recoil spring 10 to the stock end 7 via the fixed rod body 8, and this reaction force It is possible to give the shooter a feeling that the gun body 1 is swinging.

  In this way, after the weight 6 is pushed back by the restoring force of the coil spring 17, it immediately moves forward by the restoring force of the recoil spring 10, and as shown in FIG. Contact 17 and prepare for the next shot. In addition, when switching to continuous shooting, the above operation is repeated, and the swinging sensation given to the shooter by the restoring force of the coil spring 17 can be more clearly manifested.

  In the above embodiment, the buffer spring 18 and the small-diameter movable rod 19 are provided in the tubular transmission member 14 protruding rearward from the rear end surface of the piston 4. Without providing the movable rod 19, the rear end surface of the transmission member 14 may be pressed against the front end surface of the weight 6 so that the weight 6 is moved backward against the elastic force of the recoil spring 10. . In this case, the transmission member 14 may be configured to transmit the rearward movement of the transmission member 14 to the weight 6 via a buffer spring as necessary.

  Further, without using the transmission member 14, the elastic spring 16 'is interposed between the piston 4 and the weight 6 as shown in FIG. In this case, the recoil spring 10 is disposed in the weight 6 provided in the weight storage chamber 5 so as to be movable back and forth. If the end is received by the front end of the fixed rod body 8 projecting forward from the stock end 7 and the recoil spring 10 is compressed and stretched, the weight 6 rebounds to generate a recoil. Can be satisfied.
