Also, a buffering coil spring 8 is disposed in the front end of the weight working chamber 5. An inertial force of the weight 6 is increased by a retreat force of the piston 4 and a spring force of the buffering coil spring 8 at the retreating of the piston 4, so that an accumulated pressure is increased by the compression of the recoil spring 7, and thereby a large recoil is transmitted to a shooter when the weight 6 retreats and advances.

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 in the normal state, the outer peripheral portion of the front end surface of the weight is provided on the inner peripheral surface of the front portion of the weight working chamber by the elastic force of the recoil spring. This step is used as a stopper to prevent further advancement of the weight, and a rod of a certain length projects forward from the center of the front end surface of the weight. The rod is slidably passed through the rear wall of the engine room, and the front end of the rod is brought into contact with the rear end surface of the piston when the piston is retracted so that the weight can be pushed backward. It has the structure which becomes.

  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 generating device in the toy gun, the weight is always urged forward by the recoil spring, and before the operation, the weight in the length direction of the weight working chamber is caused by the pressing force of the recoil spring. Since it is in a state of being pressed against the stopper consisting of the stepped peripheral portion provided on the inner peripheral surface of the intermediate portion, when generating a reaction, in order to push the weight backward via the rod by retreating the piston, The recoil spring must be compressed against the pressing force of the recoil spring. Therefore, the reverse speed of the weight, that is, the backward motion acceleration becomes small, and a large reaction cannot be generated.

  Furthermore, as described above, the weight is configured to move backward from the position of the stopper portion formed of the stepped peripheral portion provided in the intermediate portion in the length direction of the weight working chamber to generate a reaction. The moving distance becomes relatively short and it is difficult to set the length of the weight sufficiently, and the weight of the weight has to be lightened. The reaction force is reduced, making it difficult for the shooter to experience a sufficient reaction.

  In addition, when the weight moves backward by compressing the recoil spring by the backward movement of the piston, the urging force to the rear is released by the advance of the piston, and the weight moves forward by the elastic restoring force of the recoil spring. There is a problem that the stopper made of the peripheral step is impacted and received, and the impact force acts in a 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 increase the motion acceleration and the moving distance of the weight in the weight working chamber in the weight working chamber when the reaction is generated, and the weight. It is also possible to provide a reaction generator for a toy gun that can be set to a relatively large weight, can generate a large reaction, and can be operated smoothly without causing a sense of incongruity to the shooter.

  In order to achieve the above object, a reaction generator for a toy gun according to the present invention is provided with a gun body and an engine room of the gun body, as described in claim 1, and in conjunction with a trigger operation, a cylinder A piston that moves back and forth in the interior, a coil spring that always presses the piston forward, a weight working chamber that is located behind the cylinder chamber and that is located behind the rear wall of the engine chamber, and a front and rear of the weight working chamber. A weight that is movably mounted; a biasing means that biases the weight forward; and a transmission member that transmits the retreating force of the piston to the weight through a through hole provided in the rear wall of the engine chamber. When the piston moving back and forth by a trigger operation is retracted, the retracting force is transmitted to the weight via the transmission member, and the weight is retracted against the urging force of the urging means to advance the piston. Time In the reaction generator for a toy gun configured to transmit a reaction force when the weight moves forward by the urging force of the urging means to the rear wall surface of the weight operation chamber, the front end surface of the weight is placed in the front end portion of the weight operation chamber. A buffer coil spring that can be received is provided.

  In the reaction generator for a toy gun configured as described above, the invention according to claim 2 is such that when the weight is retracted, the front end of the buffer coil spring is separated from the rear surface of the rear wall of the engine room, or the rear end of the buffer coil spring is The length of the buffer coil spring is set so as to be separated from the front end of the weight.

  The invention according to claim 3 relates to a preferred structure of the urging means, and comprises a recoil spring interposed between the rear end surface of the weight in the weight working chamber and the rear wall surface of the weight working chamber. It is characterized by that.

  The invention according to claim 4 relates to still another preferable structure of the urging means, and is fixed to the rear end surface of the weight and the rear end surface of the weight working chamber with the same magnetic poles facing each other so as to generate a repulsive force. It is characterized by comprising a pair of permanent magnets.

  In the invention according to claim 5, a recoil spring as an urging means is not provided between the rear end surface of the weight in the weight working chamber and the rear wall surface of the weight working chamber, and a spring storage chamber is provided in the weight. The recoil spring is disposed in the spring storage chamber, and a fixed rod body is projected from the rear wall surface of the weight working chamber so that the fixed rod body communicates with the spring storage chamber from the rear end of the weight. The rear end surface of the recoil spring is received by the front end surface of the fixed rod body, and the reaction generated when the weight is operated is transmitted to the rear end surface of the weight working chamber via the fixed rod body. It is configured as follows.

  In the invention according to claim 6, the transmission member for transmitting the retreating force of the piston to the weight has its front end fixed to the center of the rear surface of the piston, while the rear end can be brought into contact with the front end surface of the weight. It is characterized by being separated from the front end face by a small distance forward.

  According to the first aspect of the present invention, the buffer coil spring capable of receiving the front end surface of the weight is disposed in the front end portion of the weight working chamber, and the urging means for urging the weight forward is disposed in the rear portion. Therefore, after the piston is moved backward and the weight is pushed rearward against the biasing force of the biasing means via the transmission member, when the piston is advanced to release the pressure on the weight, the weight is released from the biasing means. Due to the urging force, it rapidly moves forward and collides with the buffer coil spring, and this buffer coil spring can be compressed to absorb the impact force of the weight, so that it can shoot without giving the shooter a sense of incongruity In addition to being able to do this, the above-described buffer coil spring is used to press the piston back when the weight is pushed backward through the transmission member by retreating the piston. At the same time, the restoring force of the buffer spring can be applied to the weight, the motion acceleration of the weight is increased, and a large repulsive force is instantaneously accumulated in the urging means to generate a large reaction (recoil shock) at the time of the repulsion. be able to.

  Further, since the weight is formed so as to reach the buffer coil spring provided at the front end of the weight working chamber from the biasing means in the rear portion of the weight working chamber, the weight thereof becomes relatively large and the motion acceleration is increased. The inertial force at the time of moving backward acting together increases, and the repulsive force can generate a large reaction force on the rear end face of the weight working chamber to make the shooter feel a strong reaction.

  According to the invention of claim 2, when the weight is retracted, the buffer coil spring has a front end separated from the rear surface of the rear wall of the engine room, or a buffer coil spring so that a rear end is separated from the front end of the weight. Since the length of the spring is set, when a reaction occurs, when the weight is retracted against the biasing force of the biasing means by the pushing force of the buffer coil spring and the piston, the weight is buffered by the coil spring. Or the buffer coil spring is separated from the rear wall rear surface of the engine room to the rear, and the weight is rapidly suppressed without the action force at the start of pushing back of the weight by the biasing means being suppressed by the buffer coil spring. It can be moved forward and a large reaction can be generated.

  Further, according to the invention according to claim 3, since the urging means comprises a recoil spring interposed between the rear end surface of the weight in the weight working chamber and the rear wall surface of the weight working chamber, When the piston is retracted and the weight is pushed backward through the transmission member, and at the same time the elastic force of the buffer coil spring is applied to the weight, the weight is moved backward by a large inertial force to greatly compress the recoil spring. The compression force can be transmitted to the rear wall of the weight working chamber while the piston is advanced to release the pressure against the weight, and the weight is rapidly moved forward by the strong elastic restoring force of the recoil spring. It can be moved, and the reaction force generated at that time can make the archer feel a large reaction Kill.

  On the other hand, according to the invention of claim 4, the biasing means is fixed to the rear end face of the weight and the rear end face of the weight working chamber with the same magnetic poles facing each other so as to generate a repulsive force. Since it is composed of a permanent magnet, the piston is retracted as described above to push the weight backward through the transmission member, and at the same time, the elastic force of the buffer coil spring is applied to the weight to cause the weight to have a large inertial force. When moved rearward, the permanent magnet fixed to the rear end surface of the weight approaches the permanent magnet fixed to the rear end surface of the weight working chamber, and the repulsive force between these permanent magnets increases rapidly. Therefore, it is possible to obtain an urging force larger than the urging force by the spring. Therefore, when the piston is advanced and the pressure against the weight is released, the weight is generated by the repulsive force of both permanent magnets. The reaction force acting toward the forward abruptly pushed back to the rear end surface of the weight can also be increased from at urged by the spring, it is possible to experience a large recoil shooter.

  According to the fifth aspect of the present invention, the spring storage chamber is provided in the weight, the recoil spring as the urging means is disposed in the spring storage chamber, and the fixed rod body is provided on the rear wall surface of the weight operation chamber. Since the fixed rod body protrudes and is inserted into the insertion hole communicating with the spring storage chamber from the rear end of the weight, the rear end surface of the recoil spring is received by the front end surface of the fixed rod body. The weight can be moved by guiding the fixed rod until it reaches the rear wall of the weight working chamber. Therefore, the moving distance of the weight can be lengthened and the recoil spring provided in the weight can be lengthened as much as possible. The amount of compression and extension can be increased, and the weight is transferred to the rear wall of the weight storage chamber as the weight moves backward. It is possible to remarkably increase the reaction force of the recoil spring is a large recoil shooter and can be impulsively directly collide with the wall surface after the weight operation chamber weights can be experienced.

  According to the invention of claim 6, the transmission member for transmitting the retreating force of the piston to the weight has its front end fixed to the center of the rear surface of the piston, while the rear end can be brought into contact with the front end surface of the weight. Since the piston is moved backward from the front end surface with a small gap, the weight is pushed backward through the transmission member against the biasing force of the biasing means, and then the piston is advanced. When the weight is released and the weight is moved forward by the urging force of the urging means, the front end surface of the weight is directly collided with the buffer spring without colliding with the transmission member to compress the buffer spring. In addition, when the elastic force of the buffer spring is restored, the transmission member is pressed against the weight again by the backward movement of the piston. It is possible to generate a large reaction by increasing the inertia of the.

  A specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a rifle-type toy gun equipped with a recoil generating device, in which a barrel A is integrally provided on the front end side and a stock base B is integrally provided on the rear end side. In the engine body 2 of the gun body 1, a cylinder 3 is disposed and fixed with its center on the same axis as the barrel A, and a piston 4 is slidably mounted in the cylinder 3 so as to be slidable in the front-rear direction. Further, a cylindrical weight working chamber 5 that is long in the front-rear direction is disposed behind the rear wall 2a of the engine chamber 2 with the center thereof on the same center line as the cylinder 3, and the front end of the weight working chamber 5 is located at the engine. The rear end of the chamber 2 is fixed to the rear surface 2a, and the rear end is fixed to the front end of the base B integrally.

  In the weight working chamber 5, a circular rod-like weight 6 long in the front-rear direction is disposed so as to be movable back and forth. The weight 6 is moved forward between the rear end surface of the weight 6 and the rear end surface of the weight working chamber 5. A recoil spring 7 is disposed as a biasing means for biasing, and a buffer coil spring 8 capable of receiving the front end surface of the weight 6 is disposed in the front end portion of the weight working chamber 5. The front end portion of the weight 6 is formed in a head portion 6a having a diameter smaller than the diameter of the body portion of the weight 6 and the inner diameter of the buffer coil spring 8. However, the head portion 6a is not necessarily provided.

  The front end of the buffer coil spring 8 is fixed to the rear surface of the rear wall 2a of the engine room 2. On the other hand, when the weight 6 is not in operation, the rear end thereof is the front end of the small-diameter head 6a of the weight 6. When the weight 6 moves forward, the weight front 6 receives the front end surface of the outer periphery of the proximal end of the small-diameter head 6a at the rear end thereof and compresses it as the weight 6 advances. However, the front end of the buffer coil spring 8 is disposed between the rear wall 2a and the front end surface of the weight 6 without fixing the front end of the buffer coil spring 8 to the rear surface of the rear wall 2a of the engine room 2. Sometimes, the engine room 2 may be configured to be separated from the rear wall 2a. In this case, the weight 6 is configured so that the rear end of the buffer coil spring 8 can be brought into contact with and separated from the front end surface of the weight 6 without providing the small-diameter head 6a.

  In the recoil spring 7, the rear end is fixed to the rear end surface of the weight working chamber 5, while the front end is in contact with and separated from the rear end surface of the weight 6 when not operating, When the recoil spring 7 is compressed and expanded by its restoring force to push the weight 6 back forward, the weight 6 is separated from the front end of the recoil spring 7 that has reached the expansion limit, and the rear end and the front end of the recoil spring 7 A gap is formed between the two.

  In this recoil spring 7, the rear end surface may be brought into contact and separation without being fixed to the rear end surface of the weight working chamber 5. In short, the rear end surface of the weight 6 and the rear end surface of the weight working chamber 5 may be arranged. A recoil spring 7 may be disposed between them.

  A through-hole 12 communicating with the weight working chamber 5 is formed in the rear wall 2a of the engine chamber 2 in the gun body 1. The through-hole 12 is formed to have a smaller diameter than the buffer coil spring 8, and is configured such that a small-diameter bar-shaped transmission member 9 that transmits the retraction to the weight 6 when the piston 4 is retracted is inserted into the through-hole 12. Yes.

  The transmission member 9 has its front end integrally fixed to the central portion of the rear surface of the piston 4. When the piston 4 is not in operation, its rear end faces the opening end of the through hole 13 to operate the weight. The front end surface of the small-diameter head 6a of the weight 6 in the chamber 5 is spaced forward from the front end surface of the small-diameter head 6a. The weight 6 is configured to move rearward by coming into contact with the front end of 6a, but the piston 4 is slidably inserted into and supported by the through-hole 13 without fixing its tip. The front end of the piston 4 may be brought into contact with the rear surface of the piston 4 and moved rearward together with the piston 4 so that the rear end thereof is brought into contact with the front end of the small-diameter head 6a of the weight 6. .

  Further, a piston pressing coil spring 10 is interposed between the rear surface of the piston 4 and the front surface of the engine room rear wall 2a around the through hole 12 so as to always press the piston 4 forward. . The coil spring 10 projects forward from the front surface of the engine room rear wall 2a around the through hole 12 so that the coil spring 10 can be accurately expanded and contracted around the transmission member 9 in the length direction of the transmission member 9. The rear portion of the small-diameter cylindrical spring guide member 11 is supported to be extendable and contractible.

  Also, a bullet loading section 13 communicating with the rear end of the barrel A is provided between the barrel A of the gun body 1 and the engine room 2. When the piston moves backward, the bullet 15 is sent from the magazine 14 to the bullet loading section 13, and when the piston 4 moves forward, the bullet 15 is fired from the muzzle by the compressed air generated in the cylinder 3.

  The piston driving means is disposed in the lower part of the engine chamber 2 and, as shown in FIG. 1, a rack 16 is formed at the lower end of the piston 4 built in the cylinder 3, and the rack 16 has a sector gear. 17 is engaged, and the rotation of the sector gear 17 retracts the piston 4 while compressing the coil spring 10 for pressing the piston. When the toothless portion of the sector gear 17 faces the rack 16, the engagement is released and the piston 4 is released. Is rapidly advanced by the restoring force of the piston pressing coil spring 10.

  The sector gear 17 is rotated through a meshing gear train 19 driven by a motor 18. The motor 18 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 use of the toy gun, the piston 4 is located at the front of the cylinder 3 by the piston pressing coil spring 10 and, as shown in FIG. The rear end of 9 faces the front end opening of the through hole 12 provided in the rear wall 2a of the engine room 2, and the weight 6 in the weight working chamber 5 is pushed forward by the recoil spring 7 to The front end of the head 6a is held at the rear end of the buffer coil spring 8, or when the head 6a is not provided, the front end surface of the weight 6 is brought into contact with the rear end surface of the buffer coil spring 8 or It is close. Further, the sector gear 17 meshes with the rear end portion of the rack 16 formed at the lower end portion of the piston 4.

  When the motor 18 is driven by pulling the trigger 20 from this state and the sector gear 17 is rotated via the meshing gear train 19, the piston 4 having the rack 16 meshed with the sector gear 17 is moved to the piston pressing coil. Retracts rapidly while compressing the spring 10. As the piston 4 moves backward, the rear end of the transmission member 9 integral with the piston 4 comes into contact with the small-diameter head 6a of the weight 6 as shown in FIG. 6 is pushed backward while compressing the recoil spring 7, and when the weight 6 moves back to the position where the recoil spring 7 is compressed to the maximum as shown in FIG. 4, the sector gear 17 is disengaged from the rack 16. The piston 4 is instantaneously moved forward as shown in FIG. 5 by the restoring force of the piston pressing coil spring 10 to separate the rear end of the transmission member 9 from the front end surface of the head of the piston 4. As the recoil spring 7 is uncompressed and the piston 4 moves forward, the recoil spring 7 turns into an extension by a restoring force. The weight 6 as shown in moving forward.

  The piston 4 starts retreating and the weight 6 moves to the rear end side of the weight working chamber 5 while compressing the recoil spring 7, and the piston 4 is restored to the piston pressing coil spring 10 following this operation. The operation of moving the weight 6 forward by the repulsive force of the recoil spring 7 at the same time as the force moves forward to the original position is instantaneously performed, and the powerful rebound acting force when restoring from the compression of the recoil spring 7 is the weight operation. The reaction force can be transmitted to the rear end face of the chamber 5 as a reaction force, and the reaction force can be experienced by the shooter as a reaction (recoil shock).

  Further, when the sector gear 17 is disengaged from the rack 16 and the piston 4 is instantaneously advanced to the original position by the restoring force of the piston pressing coil spring 10, the piston 4 is integrated with the piston 4 pressed against the front end surface of the weight 6. The rear end of the transmission member 14 returns from the buffer coil spring 8 to the original position in the rear end portion of the engine room 2 through the through hole 12, and at the same time, the weight 6 is rapidly moved forward by the restoring elastic force of the recoil spring 7, and the recoil spring. 6, when the rear end of the weight 6 is separated from the front end of the recoil spring 7, the front end surface collides with the buffer coil spring 8 as shown in FIG. Then, the buffer coil spring 8 is compressed.

  The weight 6 is braked while absorbing the impact force of the weight 6 against the buffer coil spring 8 by the compression of the buffer coil spring 8, and the weight 6 is immediately stopped by the restoring force of the buffer coil spring 8 after stopping the forward movement of the weight 6. Is reversed and moved backward.

  At this time, when the buffer coil spring 8 changes from compression to extension, the sector gear 17 is engaged with the rack 16 in conjunction with the operation of the buffer coil spring 8 and the piston pressing coil spring 10 is compressed. 4 is retracted instantaneously, the rear end of the transmission member 9 is brought into contact with the front end surface of the head 6a of the weight 6, and the motion acceleration of the weight 6 is increased by the transmission member 9 together with the restoring force of the buffer coil spring 8. While generating a large inertial force on the weight 6, the weight 6 is moved rearward with the inertial force and is brought into impact contact with the recoil spring 7 with a strong force, and the recoil spring 7 is greatly compressed to the maximum. Possess strong resilience.

  Accordingly, the restoring force of the recoil spring 7 increases the reaction force acting on the rear end surface of the weight working chamber 5 when the recoil spring 7 starts to expand, and the archer can feel a large reaction (recoil shock) due to the reaction force. be able to.

  In this way, a large inertia force is generated in the weight 6 by the restoring force of the buffer coil spring 8 and the retraction force of the transmission member 9 due to the retraction of the piston 4, and the weight 6 is moved rearward by the inertia force and the recoil spring 7. , The recoil spring 7 is compressed, and following this operation, the weight 6 is reversely moved forward by the restoring force of the recoil spring 7 when the pressure of the weight 6 is released by the forward movement of the piston 4. Depending on the operation, a large recoil can be generated on the rear end face of the weight working chamber 5 each time the piston 4 reciprocates back and forth.

  FIG. 7 shows another embodiment of the present invention. In the above embodiment, the recoil spring 7 is used as a biasing means disposed in the rear portion of the weight working chamber 5 to press the weight 6 forward. However, in this embodiment, the urging means is not affected by the recoil spring 7 and the repulsive force is generated between the rear end surface of the weight 6 and the rear end surface of the weight working chamber 5 facing the rear end surface. It is composed of a pair of permanent magnets 71 and 72 that are fixed with the magnetic poles facing each other. Since other configurations are the same as those in the above embodiment, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  With this configuration, before the operation, the weight 6 is pressed toward the front side in the weight operation chamber 5 by the repulsive force of the permanent magnets 71 and 72, and the front end surface thereof abuts against the buffer coil spring 8. Or in a close proximity.

  When the motor 18 is driven by pulling the trigger 20 from this state and the sector gear 17 is rotated via the meshing gear train 19, the piston 4 having the rack 16 meshed with the sector gear 17 is moved to the piston pressing coil. Retracts rapidly while compressing the spring 10. As the piston 4 moves backward, the rear end of the transmission member 9 integral with the piston 4 comes into contact with the small-diameter head 6a of the weight 6 as shown in FIG. Is pushed backward against the repulsive force of the permanent magnets 71, 72.

  The piston 4 moves backward until just before the sector gear 17 is disengaged from the rack 16, and when the weight 6 approaches the rear end surface of the weight working chamber 5 as shown in FIG. 9, the weight 6 is forced to push forward. When the repulsive force of the magnets 71 and 72 reaches the maximum and the meshing of the sector gear 17 with the rack 16 is released from this state, the piston 4 is integrated with the transmission member 9 by the restoring force of the piston pressing coil spring 10. The weight 6 moves forward by the repulsive force of the permanent magnets 71 and 72 so as to follow the forward movement of the piston 4 simultaneously with the forward movement to the original position instantly.

  The repulsive force of the permanent magnets 71 and 72 is usually larger than the elastic force of the recoil spring 7. The repulsive force causes the weight 6 to rapidly advance and its front end surface collides with the buffer coil spring 8 as shown in FIG. The buffer coil spring 8 is compressed as shown in FIG.

  The compression of the buffer coil spring 8 brakes the weight 6 while absorbing the impact force applied to the buffer coil spring 8 by the weight 6, and immediately stops the forward movement of the weight 6 in the same manner as in the above embodiment. The weight 6 is reversely moved backward by the restoring force.

  At this time, when the buffer coil spring 8 changes from compression to extension, the sector gear 17 is engaged with the rack 16 in conjunction with the operation of the buffer coil spring 8 and the piston pressing coil spring 10 is compressed. 4 is retracted instantaneously, the rear end of the transmission member 9 is brought into contact with the front end surface of the head 6a of the weight 6, and the motion acceleration of the weight 6 is increased by the transmission member 9 together with the restoring force of the buffer coil spring 8. While generating a large inertial force in the weight 6, the weight 6 is moved backward by the inertial force to bring the permanent magnets 71 and 72 closer together, and the repulsive force by these permanent magnets 71 and 72 is increased.

  Accordingly, the reaction force acting on the rear end surface of the weight working chamber 5 when the weight 6 moves forward due to the repulsive force of the permanent magnets 71 and 72 increases, and a large reaction (recoil shock) due to the reaction force is applied to the shooter. You can feel it.

  FIG. 11 shows still another embodiment of the present invention. In the embodiment shown in FIG. 1, the recoil is provided as a biasing means disposed in the rear portion of the weight working chamber 5 to press the weight 6 forward. In the embodiment shown in FIG. 7, a pair of permanent magnets 71 and 72 having the same magnetic poles opposed to each other so as to generate a repulsive force are used as the biasing means. These use urging means for both the recoil spring 7 and the pair of permanent magnets 71 and 72.

  That is, a recoil spring 7 for urging the weight 6 forward is disposed between the rear end surface of the weight 6 disposed in the weight working chamber 5 so as to be movable back and forth and the rear end surface of the weight working chamber 5. At the same time, the pair of permanent magnets 71 and 72 are fixed with the magnetic poles facing each other so that a repulsive force is generated between the rear end surface of the weight 6 and the rear end surface of the weight working chamber 5 facing the rear end surface. is there. Since other configurations are the same as those in the above embodiment, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  Thus, by using the recoil spring 7 and the pair of permanent magnets 71 and 72 as the biasing means for biasing the weight 6 forward, the weight 6 is retracted integrally with the piston 4 by the retraction of the piston 4. When pushing forward by the elastic force of the buffer coil spring 8 together with the pushing force of the transmitting member 9 to be pushed forward, the accumulated pressure for pushing the weight 6 forward becomes extremely large, and when the weight 6 advances by this pressure The reaction force acting on the rear end face of the weight working chamber 5 is further increased, and a large reaction can be experienced by the shooter.

  Next, in any of the above-described embodiments, the weight 6 is configured to be urged forward by the urging means from the rear in the weight working chamber 5, but as shown in FIG. A structure in which a recoil spring 7 ′ as an urging means is disposed may be employed.

  The structure of this urging means will be described in detail. A fixed rod body 21 having a length reaching the middle of the weight working chamber 5 is projected from the center of the rear end surface of the weight working chamber 5 while A spring housing chamber 22 having a constant diameter having a length reaching the rear portion from the front end portion of the weight 6 is provided in the central portion of the weight 6, and the front end is received by the rear surface of the front end wall of the weight working chamber 5 in the spring housing chamber 22. A recoil spring 7 ′ that is stopped is housed, and an insertion hole 23 of the fixed rod body 21 is formed from the rear end of the spring housing chamber 22 to the rear end of the weight 6. The fixed rod body 21 is inserted, and the rear end surface of the recoil spring 7 ′ is received by the front end surface of the fixed rod body 21.

  The length and weight of the weight 6 are determined by whether the rear end surface of the weight 6 abuts the rear end surface of the weight working chamber 5 when the weight 6 moves backward using the fixed rod body 21 as a guide by compressing the recoil spring 7 '. Or, it is set to an appropriate length and weight so as to reach a close position with a slight gap. Since other configurations are the same as those in the above embodiment, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  With this configuration, the weight 6 is lightly urged forward by the recoil spring 7 ′ in the weight 6 whose rear end is received by the front end face of the fixed rod body 21 before the operation. The front end face is brought into contact with the buffer coil spring 8 by the biasing force, or the small-diameter head 6a of the weight 6 is inserted into the rear end of the buffer coil spring 8.

  When the motor 18 is driven by pulling the trigger 20 from this state and the sector gear 17 is rotated via the meshing gear train 19, the piston 4 having the rack 16 meshed with the sector gear 17 is moved to the piston pressing coil. Retracts rapidly while compressing the spring 10. By the retraction of the piston 4, the rear end of the transmission member 9 integrated with the piston 4 comes into contact with the small-diameter head 6 a of the weight 6, and the weight 6 is moved from the buffer coil spring 8 by the transmission member 9 as the piston 4 retreats. The recoil spring 7 'is pushed away while being separated and compressed.

  When the piston 4 moves backward until the sector gear 17 is disengaged from the rack 16 and the weight 6 is brought close to the rear end surface of the weight working chamber 5 as shown in FIG. 13, the amount of compression of the recoil spring 7 'is maximized. In this state, when the meshing of the sector gear 17 with the rack 16 is released, the piston 4 is instantaneously moved forward to the original position integrally with the transmission member 9 by the restoring force of the piston pressing coil spring 10. The weight 6 is rapidly advanced by the repulsive force due to the elastic recovery of the recoil spring 7 ′ so that the piston 6 can instantaneously follow the advance of the piston 4 by releasing the pressing force from the transmission member 9. The buffer coil spring 8 is compressed as shown in FIG.

  The compression of the buffer coil spring 8 brakes the weight 6 while absorbing the impact force applied to the buffer coil spring 8 by the weight 6, and immediately stops the forward movement of the weight 6 in the same manner as in the above embodiment. The weight 6 is reversely moved backward by the restoring force.

  At this time, when the buffer coil spring 8 changes from compression to extension, the sector gear 17 is engaged with the rack 16 in conjunction with the operation of the buffer coil spring 8 and the piston pressing coil spring 10 is compressed. 4 is retracted instantaneously, the rear end of the transmission member 9 is brought into contact with the front end surface of the head 6a of the weight 6, and the movement of the weight 6 is caused by the rear end force of the transmission member 9 together with the restoring force of the buffer coil spring 8. The acceleration is increased, a large inertia force is generated in the weight 6, the weight 6 is moved away from the buffer coil spring 8 by the inertia force, and further moved rearward, and the recoil spring 7 ′ is greatly compressed, and at the same time the weight 6 The rear end surface of the weight working chamber 5 is made to collide with the rear end surface of the weight working chamber 5 by its inertial force, and the rear end surface of the weight working chamber 5 is generated on the rear end surface of the weight working chamber 5 when rebounding after the collision. Along with the large reaction force, the archer can experience a strong reaction due to the reaction force transmitted to the rear end face of the weight working chamber 5 via the fixed rod body 21 when the recoil spring 7 'changes from compression to extension. Can do.

  In addition, the weight 6 may be configured to reversely move forward after reaching a close position without colliding with the rear end face of the weight working chamber 5. In this case, the weight working chamber As described above without depending on the impact force applied to the rear end surface of 5, the reaction force transmitted to the rear end surface of the weight working chamber 5 via the fixed rod body 21 when the recoil spring 7 ′ changes from compression to extension. You can feel the reaction.
