Description

  The present invention includes a gun body including a barrel assembly having a nozzle assembly for injecting compressed gas from a tip nozzle portion and a bullet loading portion for loading a bullet, and the nozzle assembly is moved backward between the tip nozzle portion and the bullet loading portion. The present invention relates to a device that can change the number of bullets in a bullet feed mechanism that supplies bullets to the tank.

  For a gun commonly called a toy gun or a simulated gun, a spherical plastic bullet called a BB bullet is used. Many guns are loaded with a single bullet in the barrel's loading section, and thus the operation of firing a single bullet in a single cocking operation is repeated. On the other hand, there is also a gun having a structure for firing a plurality of bullets, and the applicant of the present invention has applied for, for example, Japanese Patent Application Laid-Open No. 11-94495 (Patent No. 3045984). The invention of the same issue discloses a loading device for loading a bullet into a gun having a plurality of barrels, and the bullets are automatically loaded into each barrel one by one from the chamber front chamber leading to each barrel. The gun having the above-described configuration can load and fire the same number of bullets as the number of barrels, but the number of bullets to be loaded cannot be increased beyond the number of barrels.

  For example, Japanese Patent Application Laid-Open No. 2004-324962, which is a multiple bullet firing device, emits a plurality of bullets. In the invention, a cylindrical warhead is divided into six bullet chambers and a large gas-filled cylinder at the center, and four plastic bullets are loaded in each of the surrounding bullet chambers. Thus, it is possible to fire 24 bullets at the same time. However, when loading bullets, it is stated that the bullet must be inserted from the tip of the barrel to the bottom of the bullet chamber against the convex part of the seal material. Since it is necessary to insert, it is very troublesome. Further, in the prior art having the same configuration, it is described that when a bullet is loaded, the warhead is removed and a plurality of bullets are loaded again (filled with gas) and then mounted on the barrel.

  Thus, the device described in the above invention remains very cumbersome for the operation of loading the bullets themselves. In addition, the invention of the above-mentioned multiple bullet firing device takes a method of inserting one shot at a time, and it is not possible to change the number of bullets loaded by operation, and technical matters relating to the change of the number of bullets loaded are suggested. Not even. In such a situation, the inventor of the present invention intends to establish a technique for loading a plurality of bullets and a technique for switching the number of bullets for loading a plurality of bullets. Is completed.

JP-A-11-94495 Japanese Patent Application Laid-Open No. 2004-324962

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a loading number switching device capable of switching the number of bullets loaded in a barrel in a bullet feeding mechanism. Another object of the present invention is to provide a bullet feed mechanism in which the number of bullets to be loaded can be switched by a cocking member of either a one-way operation method or a reciprocation operation method provided on the gun body. It is to provide a loading number switching device.

  In order to solve the above-described problems, the present invention includes a gun body including a barrel having a nozzle assembly for injecting compressed gas from a tip nozzle portion and a bullet loading portion for loading a bullet, and the tip nozzle portion is retracted by retreating the nozzle assembly. And a bullet feeding mechanism for supplying a bullet between the bullet loading part and the cocking member attached to the gun body so as to be movable in the forward and backward direction of the nozzle assembly, and the movement of the cocking member is transmitted to the nozzle assembly, The nozzle assembly against the biasing force of an action member provided between the cocking member and the nozzle assembly for moving the nozzle assembly backward and an elastic member biasing the nozzle assembly in the forward direction. Engagement means provided on the cocking member and the action member for retreating the lever, and whether or not the engagement in the engagement means is valid In order to select whether or not the movement of the cocking member is transmitted to the nozzle assembly by selecting whether or not to be effective, a means is provided to include a loading number switching member that switches the working member. Is.

  A bullet feed mechanism that provides a space for supplying a bullet between the tip nozzle portion and the bullet loading portion by retreating the nozzle assembly is a premise of the device of the present invention, but this method itself is known. For example, the thing of the above-mentioned patent document 1 is also the same. It can be said that the device of the present invention switches the number of bullets by repeating the backward movement of the tip nozzle portion in such a bullet feeding mechanism.

  For this reason, the apparatus of the present invention is provided with a cocking member attached to the gun body so as to be movable in the forward and backward direction as an operation member for performing the operation for switching the number of bullets, and for transmitting the movement of the cocking member to the nozzle assembly to move backward. An action member provided between the cocking member and the nozzle assembly, and an engagement member provided on the cocking member and the action member to retract the nozzle assembly against an urging force of an elastic member for urging the nozzle assembly in the forward direction. In order to select whether or not to transmit the movement of the cocking member to the nozzle assembly by selecting the coupling means and whether to enable or disable the engagement in the engagement means, It is equipped with an ammunition number switching member for switching.

  Therefore, according to the present invention, the number of times the nozzle assembly is retracted, that is, the number of bullets to be loaded can be controlled by switching the action member when the cocking member is moved in the forward and backward direction. The operation of the cocking member is transmitted to the nozzle assembly via the action member. Therefore, the number of times the nozzle assembly is retracted can be changed by controlling the number of times that the action member is transmitted. The cocking member and the working member are engageable by the engaging means, so that selecting whether the engagement is valid or not means whether the movement of the cocking member is transmitted or not transmitted to the nozzle assembly, that is, This is control of the number of times of loading, and the number of loadings is switched.

  In the apparatus of the present invention, either one-way operation or reciprocation operation of the cocking member can be selected. The one-way operation is, for example, an operation of retracting the nozzle assembly a plurality of times by one retraction operation of the cocking member. In this case, when the cocking member moves forward, it is not involved in the change in the number of bullets, but is simply returned to the original position. In a device that performs a one-way operation, the cocking member is disposed at intervals along the moving direction. For example, the cocking member has two engaging portions and retracts the nozzle assembly by the number of times of the two engaging portions. The action member has a portion 1 that engages with the first engagement portion as an engagement partner constituting the engagement means together with the two engagement portions, and the first position. In order to release the engagement with the engaging portion of the nozzle assembly, it has a portion 2 that comes into contact with the releasing portion disposed at the rear of the nozzle assembly, and forcibly engages with the first engaging portion. And a portion 3 that comes into contact with the operation of the number-of-mounts switching member to be released and releases the engagement with the first engaging portion, and further engages with the second engaging portion. Two parts 1 are provided in the nozzle assembly.

  On the other hand, the reciprocating operation is an operation for moving the cocking member backward and forward, and the number of bullets is switched by the backward and forward operations. In the apparatus that performs the reciprocal operation, the cocking member has one engaging portion provided in the middle of the moving direction, and is configured to retreat the nozzle assembly by the reciprocating movement of the one engaging portion. The action member is attached to the gun body so as to be movable in the front-rear direction with respect to the nozzle body and the cocking member, and is also rotatably attached to the gun body. And a portion 2 composed of teeth that mesh and move with the rack on the nozzle assembly side by the rotation, and when the cocking member is retracted, The nozzle assembly is retracted by the engaging means provided on the action member and further moved from the state advanced by the urging means to the nozzle assembly following the advancement of the cocking member. Configured with a portion 3 for selecting whether to perform.

  The above-described parts 1, 2 and 3 are components necessary for both the one-way operation type device and the reciprocating direction operation type device. However, these components do not all coincide with each other in specific contents such as configuration and operation, and the contents differ depending on the difference between the one-way operation method apparatus and the reciprocal operation method method. Further, each of the portions 1 to 3 is not limited to one location but may be a plurality of locations. The present invention includes them.

  Since the present invention is configured and operates as described above, in the bullet feeding mechanism, it is possible to switch the number of bullets loaded in the barrel by operating the cocking member, and the number of bullets that can be fired is small or large. There is an effect that can also be selected. In addition, according to the present invention, there is provided a device for switching the number of bullets in a bullet feed mechanism, wherein the number of bullets to be loaded can be switched by a cocking member of either a one-way operation method or a reciprocating operation method. Therefore, there is an effect that the degree of freedom in implementation is large.

  The bullet feed mechanism 23 having such a configuration is provided with a loading number switching device. As described above, the number-of-loads switching device of the present invention can be operated in one direction or in a reciprocating direction with respect to the cocking member 31. Among these methods, the number-of-loads switching device 30 of Example 1 according to the one-way operation method shown in FIGS. 1 and 4 to 11 will be described below. First, the cocking member 31 is formed long in the front-rear direction and attached to the gun body 11 so as to be movable in the forward and backward direction of the nozzle assembly 14 (FIG. 1). As an engagement means in the bullet number switching device 30 of Example 1, an engagement portion 32 located in the middle of the cocking member 31 and a front portion of the nozzle assembly 14 are used to switch the bullet number by one-way operation. It has two places of engaging part 31b. Of the two engaging portions 32 and 31b, the first engaging portion 32 is engaged with the portion 1 (35-1), and the second engaging portion 33 is the groove portion that is the second portion 1. The nozzle assembly 14 can be engaged with the front end 31b, and the nozzle assembly 14 is retracted at the time of each engagement. The first engaging portion 32 protrudes from the upper surface of the cocking member 31, and the second engaging portion 33 protrudes to the side of the nozzle assembly 14 and has a groove portion 31 a lower than the upper surface of the cocking member 31. It can move and contact the groove front end 31b. In addition, the action member 34 is provided in the front part with the part 1 (35-1) so that it may touch the cocking member 31 with a fixed load.

  The nozzle assembly 14 is provided with a plurality of springs 11b as urging means for advancing the nozzle assembly 14 to return to the original position, and the nozzle assembly 14 is retracted against the urging force. Further, engaging means 38 are provided between the cocking member 31 and the action member 34 and between the cocking member 31 and the nozzle assembly 14, respectively. The action member 34 has a portion 1 (35-1) as an engagement partner constituting the engagement means 38 together with the first engagement portion 32, and is engaged with the first engagement portion 32. In order to release, the portion 2 (35-2) that contacts the release portion 36 disposed at the rear of the nozzle assembly is provided, and the engagement with the first engagement portion 32 is forced. It has a portion 3 (35-3) that comes into contact with the operation of the loading number switching member 37 to be released and releases the engagement with the first engaging portion 32.

  In the bullet number switching device 30 of Example 1 above, the spring 11b of the biasing means is supported at the rear end portion by the portion 11a having the air chamber 17 of the gas gun body 11, and presses the nozzle assembly 14 at the front end portion. doing. The action member 34 is rotatably supported on the side surface of the nozzle assembly 14 by a shaft 34a, and the portion 1 (35-1) is slidably provided on the upper surface of the cocking member 31 formed long in the front and rear direction. It has been. The release portion 36 is composed of an inclined surface provided on the side surface of the portion 11a having the air chamber 17 toward the front lower side, and can come into contact with the portion 2 (35-2) when it is retracted. Further, the bullet number switching member 37 is provided at the rear end portion of the barrel 15 and is provided integrally therewith, and is provided so as to be able to contact the portion 3 (35-3) with a slope directed rearward and downward. .

  The effect | action of the loading number switching apparatus 30 of Example 1 is demonstrated. First, in FIG. 1, the bullet B is pressurized by a spring inside the cartridge 24, and from this state, the bullet B is lifted up toward the bullet loading portion 15a and hits the tip nozzle portion 14e entering there. In this state, when the cocking member 31 is moved rearward as shown in FIG. 4, the portion 1 (35-1) of the action member 34 is thereby engaged with the first engaging portion 32, and the action member 34. As a result, the nozzle assembly 14 is retracted. As the nozzle assembly 14 moves backward, a space 22 (a front chamber 25) is formed between the tip nozzle portion 14e and the mounting portion 15a. Thus, the bullet B is supplied to the empty space 22 from the bullet feed path 24 a via the bullet feed mechanism 23. After supplying the first three bullets B, the action member 34 is rotated counterclockwise in FIG. 5 by moving the cocking member 31 rearward, so that the portion 1 (35-1) is one place. Since it disengages from the engagement portion 32 of the eye, the nozzle assembly 14 is pushed forward by the spring 11b of the urging means (the middle stage in FIG. 5), and the bullet B is loaded into the loading portion 15a. The space 22 between 15a is closed. At this stage, the bullets B of the three barrels 15 are loaded with a total of three bullets B, one each, and the supply of the bullets B is once cut off.

  When the cocking member 31 is further moved rearward, the action member 34 once rotates clockwise, and accordingly, the portion 1 (35-1) moves near the upper surface of the cocking member 31, and the front portion of the nozzle assembly 14 is moved. The second engaging portion 33 provided on the second portion moves in the groove portion 31a and comes into contact with the front end engaging portion 31b, so that a backward moving force is transmitted to the nozzle assembly 14 (upper stage in FIG. 6). As a result, the nozzle assembly 14 retreats, and again enters the space 22 (the front chamber 25 of the impacting portion) between the tip nozzle portion 14e and the impacting portion 15a from the bullet feeding path 24a via the bullet feeding mechanism 23, not shown. The bullet B pressed by the spring is supplied (middle stage and lower stage in FIG. 6). Thereafter, when the cocking member 31 is moved forward, the nozzle assembly 14 is pushed forward from the state in the middle of FIG. 6 by the spring 11b of the urging means (upper stage in FIG. 7), and the space 22 between the loading portion 15a and the space 22 is formed. Closes. As a result, a total of six bullets B are loaded in each of the bullet loading portions 15a of the three barrels 15 (two in each row) (lower row in FIG. 7).

Next, an operation in the case where only three shots are loaded in the loaded number switching device 30 of Example 1 will be described. In the case of loading only three shots, as shown in FIG. 8, the number-of-loads switching member 37 at the rear end of the barrel 15 is operated to push down the portion 3 (35-3) that contacts the inclined surface directed rearward and downward. Like that. Even if the action member 34 is rotated in the counterclockwise direction in advance and the first operation for retracting the cocking member 31 is performed, the portion 1 (35-1) is engaged with the first engaging portion 32. The cancel state is set so as not to match (FIG. 9). When the cocking member 31 is further moved rearward, the portion 1 (35-1) is not engaged with the first engaging portion 32, and two portions provided at the front portion of the nozzle assembly 14 are provided. Since the engaging portion 33 of the eye moves in the groove portion 31a of the cocking member 31 and comes into contact with the front end 31b, a backward moving force is transmitted to the nozzle assembly 14 (upper stage in FIG. 10). As a result, the nozzle assembly 14 moves backward, and enters the void 22 (the front chamber front chamber 25) between the tip nozzle portion 14e and the above-mentioned bullet loading portion 15a from the bullet feed path 24a via the bullet feed mechanism 23, not shown. The bullet B pressed by the spring is supplied (lower stage in FIG. 10). Thereafter, when the cocking member 31 is moved forward, the nozzle assembly 14 is pushed forward by the spring 11b of the urging means (the upper stage in FIG. 11), and the space 22 between the bullet loading portion 15a is closed. As a result, only three bullets B are loaded in the loading portions 15a of the three barrels 15 (lower row in FIG. 11).

  Furthermore, the number-of-loads switching device 40 of Example 2 according to the reciprocating direction operation method will be described with reference to FIG. In the bullet number switching device 40 of Example 2, the cocking member 41 is formed long in the front-rear direction, and is attached to the gun body 11 so as to be movable in the forward and backward direction of the nozzle assembly 14 (FIG. 12). In the loading number switching device 40 of Example 2, the cocking member 41 has one engaging portion 42 provided in the middle of the moving direction, and the one engaging portion 42 is moved by the reciprocating movement of the cocking member 41. The nozzle assembly 14 is configured to retract twice. The nozzle assembly 14 is provided with a plurality of springs 11b as urging means for moving it forward to return to the original position, and the configuration of the bullet feeding mechanism 23 and the like is the same as in Example 1. .

  The action member 43 is attached to the side of the gun body 11 so as to be movable in the front-rear direction with respect to the nozzle assembly 14 and the cocking member 41 and so as to be rotatable. Furthermore, it has a portion 1 (45-1) that engages with the one engaging portion 42 to cause rotation, and a tooth 47 that meshes with the rack 44 on the nozzle assembly side by the rotation and causes movement. The nozzle assembly is formed by the engagement of the cocking member 41 with the portion 1 (45-1) provided on the action member 43 as the cocking member 41 is retracted. Whether the nozzle assembly 14 is moved backward and further moved forward by the spring 11b of the urging means, the nozzle assembly 14 is returned to the retracted position, and the nozzle assembly 14 is moved backward as the cocking member 41 moves forward. It has the part 3 (45-3) to select.

  In the bullet number switching device 40 of Example 2, the engaging portion 42 is formed in a trapezoidal shape having a slope 42a, 42b on the front and rear sides, projecting substantially at the center of the top surface of the cocking member 41. The action member 43 has a fan-shaped shape, and is pivotally supported by the movable member 46 at a portion 43a corresponding to the main portion 43, and a portion 1 (45-1) is formed at the front end portion of the fan-shaped arc. The part is provided with teeth 47. The movable member 46 is provided on the gun body side so as to be movable in the front-rear direction, is urged rearward by a spring 46a, and is stopped by a stopper 46b (FIG. 12B). The engagement means 50 is provided at the rear end portion of the movable member 46 so as to be engageable with the engagement claw 48b of the bullet number switching member 48 pivotally supported on the gun body side by the shaft 48a, and the engagement claw 48b. It consists of a hook-shaped engagement partner 49.

  The operation of the bullet number switching device 40 of Example 2 will be described. In FIG. 12, the bullet B is pressurized by the spring inside the cartridge 24 as in FIG. 1, and then rises from the bullet feed path 24a toward the bullet loading portion 15a and enters the tip nozzle portion 14e entering there. Assume that you are hitting. In this state, when the cocking member 41 is moved rearward, the action member 43 is moved counterclockwise in the figure by engaging and pushing up the portion 1 (45-1) to the inclined surface 42a of the engaging portion 42. Rotates (FIG. 13A) and teeth 47 engage with rack 44 in portion 2 (45-2), causing nozzle assembly 14 to retract against spring 11b. As a result, a void 22 (a bullet chamber front chamber 25) is formed between the tip nozzle portion 14e and the bullet loading portion 15a, so that the bullet B enters the void 22 from the bullet feed path 24a via the bullet feed mechanism 23. Supplied. When the cocking member 41 is further moved rearward, the action member 43 rotates in the clockwise direction in the drawing (FIG. 13B), the portion 1 (45-1) engages with the inclined surface 42b of the engaging portion 42, and the nozzle assembly 14 Moves forward under the bias of the spring 11b and the bullet B is loaded into the loading portion 15a, and the space 22 between the loading portion 15a is closed. At this stage, a total of three bullets B are loaded into the loading portions 15a of the three barrels 15 one by one.

  Next, when the operation of moving the cocking member 41 forward from the most retracted position is performed, the portion 1 (45-1) is engaged with the inclined surface 42b of the engaging portion 42 and pushed up, this time, contrary to the outward path. Then, the action member 43 rotates counterclockwise in the figure (FIG. 13C), and its teeth 47 engage with the rack 44, causing the nozzle assembly 14 to retract against the spring 11b. Therefore, a void 22 (a front chamber 25 for loading portion) is formed between the tip nozzle portion 14e and the bullet loading portion 15a, and the bullet B is supplied to the void 22 from the bullet feeding path 24a via the bullet feeding mechanism 23. . When the cocking member 41 is further moved forward, the action member 43 rotates in the clockwise direction in the drawing (FIG. 13D), the portion 1 (45-1) engages with the inclined surface 42b of the engaging portion 42, and the nozzle assembly 14 Moves forward under the bias of the spring 11b and the bullet B is loaded into the loading portion 15a, and the space 22 between the loading portion 15a is closed. As a result, a total of six bullets B are loaded into each of the bullet loading portions 15a of the three barrels 15, two shots each.

  When only three shots are loaded in the bullet number switching device 40 of Example 2, as shown in FIG. 14, the engagement means 50 is operated to engage the engagement claws 48b of the bullet number switching member 48 with the saddle type engagement. The engagement with the counterpart 49 is released (FIG. 14A). In this state, the action member 43 is urged rearward by the spring 46a and is only stopped by the stopper 46b (FIG. 12B). However, when the cocking member 41 is moved rearward, the portion 1 (45-1) is engaged with the inclined surface 42a of the engaging portion 42 and pushed up, and the action member 43 rotates counterclockwise in the figure (FIG. 14A), in part 2 (45-2), the teeth 47 engage with the rack 44, and the nozzle assembly 14 is retracted against the spring 11b. As a result, a void 22 (a bullet chamber front chamber 25) is formed between the tip nozzle portion 14e and the bullet loading portion 15a, so that the bullet B enters the void 22 from the bullet feed path 24a via the bullet feed mechanism 23. Supplied. When the cocking member 41 is further moved rearward, the action member 43 rotates in the clockwise direction in the drawing (FIG. 14B), the portion 1 (45-1) engages with the inclined surface 42b of the engaging portion 42, and the nozzle assembly 14 Advances under the urging force of the spring 11b and the bullet B is loaded into the loading portion 15a, and the space 22 between the loading portion 15a is closed, so that one shot is placed in each of the loading portions 15a of the three barrels 15. A total of three bullets B are loaded.

  Subsequently, when an operation for moving the cocking member 41 forward from the most retracted position is performed, this time, contrary to the outward path, the inclined surface 42b of the engaging portion 42 contacts the portion 1 (45-1). Although the portion 1 (45-1) is pushed up by the inclined surface 42b, it cannot resist the urging force of the spring 11b acting on the nozzle assembly 14 (FIG. 14C), and hardly recedes. A space 22 is not formed between the mounting portion 15a. When the cocking member 41 is further moved forward, the action member 43 returns to the original position. However, since the bullet is not supplied in the latter half of the reciprocating movement, only three bullets B are loaded.

  Since the apparatus of the present invention is configured in this way, the number of bullets can be switched easily and reliably. In Example 1 and Example 2, when the cocking member 41 is retracted after finishing six shots, three more bullets B are loaded, and six shots are loaded by forward movement. It is also possible to increase the number of bullets loaded. In addition, each of the above examples is a three-barrel type in which three barrels 15 are bundled, but this can be easily applied to a four-barrel or more type or single-barrel type gun. As described above, the present invention is intended for a gas gun, but the gas used is a compressed gas. Therefore, the present invention can also be applied to a gun configured using compressed air as a pressure source. It is. As for the structure of the gas source, what is shown in FIG. 1 is a built-in type in the gas gun body 11, and FIG. 12 is a detachable type in the gas gun body 41. However, as described above, the present invention can be applied to both types.
