Description

Cocking indicator device for a simulated gun

The present invention relates to a cocking indicator device in a simulated gun that performs cocking by operating an operation member provided on a gun body.

The so-called simulated gun that fires BB bullets is also called an airsoft gun, and there are various types of guns, ranging from those for young people to those targeting 18 years of age and older. In particular, guns provided for adults have been developed as high hobby elements, and for that purpose, guns having a shape, structure, and operability similar to actual guns are desired. The fact that the operability and the like is the same as that of an actual gun is desirable for a simulated gun that has recently been used for exercise purposes in the police and the like.

For example, a bolt action rifle performs cocking by operating a bolt handle provided on the gun body. This type of gun is provided with a cocking indicator so that the state of the gun, that is, whether it has been cocked or not, and the state of the gun can be grasped visually or tactilely with the cocking indicator. Previously, it seemed that there was nothing to mount a cocking indicator on a simulated gun, but there were few precedents. However, since the cocking indicator is also useful for the simulated gun, the applicant of the present application has promoted its development and has created the present invention.

When investigating the prior art, Japanese Patent Application Laid-Open No. 2004-347221 was found. The invention relates to a firing mechanism of a toy gun that makes it possible to determine whether it can be fired or not, and uses a bar-like member called an indicator bar that penetrates the piston cylinder mechanism back and forth. The piston bar mechanism is configured so that the front end of the indicator bar is in contact with the piston in the cocking state and is prevented from moving forward, and the rear end of the indicator bar protrudes to the outside so that it can be seen. It must be longer than that.

Such a long bar-like member is required as an indicator bar, and incorporating this into the gun body leads to a complicated structure. Moreover, due to the mechanism for moving it back and forth, there is a disadvantage that frictional resistance is generated at the sliding portion with the through hole, which may lead to a problem in strength. Further, the bar-shaped indicator bar pressurizes the piston forward by a spring at the time of cocking, and thus acts in a direction to increase the thrust of the piston. As a result, problems such as excessive energy acting on the bullet or unstable operation of the piston are also expected to occur.

JP 2004-347221 A

The present invention has been made in view of the above points, and its object is to make it possible to clearly grasp the cocking state only by an operation member independent of a piston cylinder mechanism or the like. Another object of the present invention is to provide a cocking indicator device in a simulated gun suitable for downsizing.

In order to solve the above-described problems, the present invention provides a simulated gun that performs cocking by operating an operation member provided on a gun body, and is disposed at a rear portion of the operation member, and a part of the cock is operated by cocking the operation member. In response to the indicator, the indicator can be moved in and out, the lock member that is locked to the indicator to keep it in the protruding state when a part of the indicator protrudes from the operating member, and the protruding state of the indicator is not protruding A means for providing a release mechanism is provided.

The cocking indicator device in the simulated gun according to the present invention includes components such as an operation member, an indicator, a lock member, and a release mechanism. Here, what is important is that the indicator is arranged at the rear part of the operation member, and that a part of the indicator is provided with an indicator that can be protruded and retracted from the operation member in response to a cocking operation of the operation member. It is.

In the cocking indicator device according to the present invention, an indicator having an arbitrary form can be adopted. That is, as described in the above-mentioned patent document, an indicator having a form suitable for the shape and structure of the simulated gun can be designed as well as not requiring a long bar-like member as described in the above-mentioned patent document.

In the present invention, a part of the indicator is in a state before cocking in which a part of the indicator is retracted from the rear part of the operation member, a state during cocking in which part of the indicator is substantially the same as the rear part of the operation member, and a part of the indicator is the operation member Three different states can be taken: the state after cocking protruding from the rear part.

From the viewpoint of grasping the cocking state, it is only necessary to know whether cocking has been made or not, so it is sufficient to take any two states such as infestation. Accordingly, claim 1 clearly includes an indicator device of this configuration. However, in some cases, it is necessary to grasp that the cocking operation is in progress, and in order to grasp this, it is necessary to indicate that the vehicle is in an intermediate state that is neither in or out.

The release mechanism acts on the lock member in conjunction with the trigger for the firing operation, and includes a shear that releases the latch of the indicator to make it non-projecting, and the lock member is sheared by engagement of the engagement means. A configuration in which the lock is released by the step is desirable in the present invention.

The indicator shows the change in the cocking state, and the cocking is terminated by the completion of the bullet firing or the completion of the firing operation (so-called air shooting), and generally the firing operation goes through the process of being transmitted from the trigger through the shear. Take composition. Therefore, it is significant to associate the indicator lock with the shear.

As a device of the present invention, in a simulated gun that operates an operation member provided on a gun body and performs cocking, the operation member is integrated with a piston cylinder mechanism provided rearwardly with respect to the gun body and a rear part thereof. A bolt member and an operation handle provided between the piston cylinder mechanism and the bolt member, and the bolt member has a hollow portion opened rearward and is disposed in the hollow portion. The indicator protrudes from the operation member by cocking operation of the operation member, the indicator can be moved back and forth in the hollow portion, and a part of the indicator is urged in the direction of moving forward of the bolt member. In order to keep the indicator protruding from the hollow part of the bolt member, the indicator provided on the gun body In addition to having a locking member that engages the locking member, it acts on the locking member in conjunction with the trigger in order to act on the locking member in the protruding state and to release the indicator to release it. A configuration having a release mechanism provided with a shear is preferable.

Since the present invention is configured and operates as described above, it is incorporated into an operation member independent of a piston cylinder mechanism and the like, and an effect is obtained that the cocking state can be clearly grasped. Further, according to the present invention, since it is incorporated in a part of the operation member, it is possible to provide a cocking indicator device in a simulated gun suitable for downsizing.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. A simulated gun 10 according to the present invention shown in the embodiment is modeled on a bolt action rifle, and includes a launcher unit 11 incorporated in a gun body, a barrel unit 12 located at the front thereof, and a launcher unit 11. It is divided roughly into each part of the stock part 13 located in the rear part.

The launching device unit 11 includes a piston 14 and a cylinder 16, and includes an operation member 20 having a piston cylinder mechanism 15 that generates compressed air for bullet firing, a firing mechanism 25 that controls a firing operation by a trigger 22, which will be described later, and It has a bullet loading mechanism 35. The piston / cylinder mechanism 15 has a piston 14 and a cylinder 16 and is attached so as to be movable in the front-rear direction of the gun body, and constitutes a front portion of the operation member 20 that performs cocking. A bolt member 21 is provided on the rear side of the piston cylinder mechanism 15 as described later, and the bolt member 21 constitutes a rear portion of the operation member 20.

The operation member 20 including the piston cylinder mechanism 15 and the bolt member 21 can move in the front-rear direction of the gun body, and an operation handle portion 17 is provided on the bolt member side in order to operate the operation member 20. The operation handle portion 17 is provided with a lever 17c having a shape and a structure imitating a member that is mounted on a bolt action rifle and serves as a bolt handle. In FIG. 1, FIG. 2, etc., the lever 17 c of the operation handle portion 17 is indicated by a two-dot chain line, but this shows only the installation position because the launching device portion is not visible in the illustrated state.

The configuration in which the piston / cylinder mechanism 15 is movably attached to the gun body is well known, and the embodiment may be the same as a general one, so detailed description will be omitted, but the basic configuration according to the embodiment is as follows. It is as follows. That is, the piston cylinder mechanism 15 has a piston spring 18 that accumulates pressure by retreating the piston 14 inserted into the cylinder 16 and advances the piston 14 by releasing the piston 14. The cylinder 16 is incorporated in the gun body so as to be able to advance and retreat. When the cylinder 16 is retracted, a space for raising the bullet B is opened at the front of the nozzle 19 at the tip, and the bullet B is barreled at the tip of the nozzle 19 at the time of advance. It is comprised so that it may load with the loading part of a rear end.

The firing mechanism 25 for performing the above-described firing operation is rotatably supported on the gun body side by a support shaft 22a and has a trigger 22 biased by a trigger spring 22b. The trigger 22 has an input portion 22c that protrudes so as to contact the intermediate member 23 on the front side, and a trigger screw 22d that adjusts the amount of protrusion relative to the intermediate member 23 on the rear side. The intermediate member 23 is pivotally supported by a support shaft 23a on the gun body side, and transmits the operation of the trigger 22 to a first shear 24 of two shears (see FIG. 3). The first shear 24 is rotatably supported on the gun body side by a front support shaft 24a, and springs 23b and 24b act on the intermediate member 23 and the first shear 24, respectively. Further, the first shear 24 has an engaging portion 33 at the rear portion, and is configured to be locked with an engaging counterpart portion 34 of an indicator lock 32 acting on an indicator 30 to be described later.

A second shear 27 is rotatably supported on the first shear 24 by a support shaft 27a, and the second shear 27 is biased by a shear spring 27b so as to protrude in the direction of the piston 14. On the other hand, an engagement portion 28 is provided at the rear portion of the piston 14 and is configured to engage with the protruding tip 29 of the second shear 27 at the piston retracted position (see FIG. 6B). Further, a slit 16 a for allowing the tip 29 to pass therethrough is formed in the longitudinal direction of the lower surface of the cylinder 16 for engagement with the piston 14.

As described above, the intermediate member 23 is pivotally supported on the gun body side at the lower portion, and is engaged with the engagement counterpart portion 26 formed at the rear portion of the first shear 24 by the engagement portion 23c formed at the upper portion. (See FIG. 3). Further, the intermediate member 23 has an arm length arbitrarily set between the support shaft 23a and the locking portion 23c. In the embodiment, the input portion 22c of the trigger 22 is in contact with the half of the intermediate member 23. .

The aforementioned operation handle portion 17 is positioned between the bolt member 21 and the piston cylinder mechanism 15 as a part of the operation member 20, and the operation handle portion 17 is provided so as to be rotatable around the longitudinal axis with respect to the piston cylinder mechanism 15. (See FIG. 4 etc.). The operation handle portion 17 is configured so that the lever 17c can be rotated from the lower position shown in FIGS. 4A to 4C to the upper position shown in FIGS. 5A to 5C for cocking operation.

The operation handle portion 17 is engaged with a recess 17a on the operation handle portion side at a portion 30a of the indicator 30 described later at a position below the lever 17c. Further, at a position above the lever 17 c, the convex portion 17 b provided so as to be able to protrude and retract on the front side of the operation handle portion 17 is engaged with a concave portion 15 b provided at the rear portion of the piston cylinder mechanism 15. By such engagement means, the lever 17c of the operation handle portion 17 is positioned at the lower position and the upper position, respectively.

The above-described indicator 30 is incorporated in the hollow portion 21a of the bolt member 21 so as to be movable back and forth, and forwardly, that is, by an indicator spring 31 disposed between the bolt member side receiving portion 21b and the indicator side receiving portion 30b. , And is biased in the direction of retracting from the hollow portion 21a. As is apparent from FIGS. 4A and 4C, the concave portion 17a on the operation handle portion side can be engaged with a part 30a of the indicator 30 only when the lever 17c of the operation handle portion 17 is in the lower position. A portion 30a of the indicator 30 protrudes slightly below the front portion thereof, and serves to stop the indicator lock 32 from rising when not operating and to stop the advancement of the indicator 30 when cocking.

The concave portion 17a on the operation handle portion side also serves as a portion into which the indicator lock 32 is inserted in order to keep the indicator 30 in a protruding state. The indicator lock 32 constitutes a lock member that keeps the indicator 30 in a protruding state, and is incorporated in the gun body side of the rear end portion of the first shear 24 described above (see FIG. 3), and the tip end portion 32a is the above-described concave portion 17a. It is urged upward by the lock spring 32b so as to enter. The tip 32a of the indicator lock 32 protrudes upward from the gun body side passage 32c.

In addition, as an engaging means with the first shear 24, a mating portion 34 for engagement with the engaging portion 33 on the first shear 24 side is provided in the indicator lock 32. The engagement portion 33 on the first shear 24 side engages with the engagement counterpart portion 34 of the indicator lock 32 to define the upper movement limit, and is lowered by the rotation of the first shear 24 so that the indicator lock 32 is moved. It operates to be removed from the indicator 30 side and unlocked. The engaging portion 33 on the first shear 24 side and the engaging counterpart portion 34 of the indicator lock 32 constitute a release mechanism that makes the protruding state of the indicator non-protruding.

The bullet loading mechanism 35 described above is a part of the simulated gun 10 and is illustrated as a type in which a detachable magazine 37 is attached to a magazine receiver 36 provided on the gun body side. The bullet B is urged forward by a magazine spring 38 from a state in which the magazine 37 is filled, and is fed to a position behind the barrel through the bullet feeding portion 39.

The operation of the cocking indicator device in the simulated gun according to the present invention configured as described above will be described with reference to FIG. FIG. 6A shows a state in which the cocking operation is not performed, the lever 17c is in the lower position, and a part 30a of the indicator 30 is engaged with the recess 17a (FIG. 4). At this time, the indicator 30 is biased by the indicator spring 31 and is in the forward position, and the rear end is in an immersive state where it enters the hollow portion 21 a of the bolt member 21.

Although the immersive indicator 30 cannot be seen from the side, it can be seen that the indicator 30 is retracted into the hollow portion 21a of the bolt member 21 when the user touches it with a fingertip. Therefore, it is confirmed that the simulated gun is not cocked and is in a safe state with no change even if the trigger 22 is operated. The ability to make a tactile judgment is also effective when the indicator 30 cannot be visually observed at night or when there is no room for visual confirmation.

Next, when the handle lever 17c is operated and rotated to the upper position for cocking, the concave portion 17a is detached from the part 30a of the indicator 30, and the convex portion 17b and the concave portion 15b of the piston cylinder mechanism 15 are engaged. A state is reached (FIG. 5). As a result, since the lever 17c is held at the upper position, it is possible to stably pull the operation member 20 rearward.

In the piston cylinder mechanism 15, the engagement portion 28 of the retracted piston 14 and the tip 29 of the second shear 27 are engaged (FIG. 6B). Accordingly, a part 30a of the indicator 30 is detached from the recess 17a and moves rearward while coming into contact with the rear surface of the operation handle portion 17. At this time, the indicator 30 is in a flush state with the bolt member 21, but this flush state can also be easily confirmed by visual or tactile sensation. As the cylinder 16 is retracted, the indicator lock 32 is raised to a position in contact with the cylinder 16 by the lock spring 32b. Further, when the bullet B is in the bullet feeding portion 39, the bullet 16 moves to a position behind the barrel as the cylinder 16 moves backward.

Furthermore, cocking is performed by pushing the operating member 20 until the lever 17c stops forward. In this state, the piston 14 of the piston cylinder mechanism 15 is kept engaged with the tip 29 of the second shear 27 at this time. Further, the lever 17c is returned to the lower position, and the concave portion 17a comes above the indicator lock 32, so that the tip end portion 32a rises and can be engaged. As the cylinder 16 advances, the bullet B is loaded into the loading portion by the nozzle 19 at the tip.

As the operation member 20 advances, a part 30a of the indicator 30 engages with the tip 32a of the indicator lock 32 biased upward, and the advancement is stopped. As a result, the indicator 30 is slightly more than the bolt member 21. It protrudes backward and enters the protruding state. By the protrusion of the indicator 30, it is clearly grasped visually and tactilely that it is in the cocking state.

When the trigger 22 is operated in a state where cocking is completed, the piston spring 18 is activated, compressed air is generated by the advance of the piston 14, and a bullet B is fired by the generated compressed air (FIG. 7B). In the firing mechanism 25, the rear end portion of the first shear 24 descends in conjunction with the operation of the trigger 22, so that the engagement portion 33 provided at the rear end portion is lowered to engage with the counterpart portion 34 of the indicator lock 32. Then, the indicator lock 32 is pushed down, and as a result, the indicator 30 is advanced by the indicator spring 31 and returns to the state where it is retracted into the hollow portion 21 a of the bolt member 21.

FIG. 8 shows an inoperative state after the bullet B is fired. The indicator 30 is retracted and the cocking operation is not performed. That is, it is the same state as FIG. 6A, and the lever 17c has moved to the lower position, thereby indicating that it has returned to the initial state. As described above, according to the present invention, in addition to the two states of protruding and immersing, the user takes the third state that is neither intruding nor recessed. The state can be grasped clearly.

Since the indicator device according to the present invention is configured as described above and can be compactly incorporated into a simulated gun as an extremely small indicator, even a long simulated gun such as a bolt action rifle can It can be implemented without the need for major changes in the internal structure. Therefore, the present invention is not limited to a rifle-type simulation gun, and can be easily transferred to, for example, a handgun-type simulation gun.
