Description

Loading indicating device in simulation gun

Technical Field

The present invention relates to a loading indicator in a simulation gun for loading by operating an operating member provided in a gun body.

Background

A so-called simulation gun for firing BB projectiles is also called an air gun, and is widely used in a wide range from a gun for teenagers to a gun for 18 years or older. In particular, a gun provided to an adult has been developed as a gun having a high interest, and thus it has been desired to have a shape, a structure, and operability similar to those of a real gun. In recent years, a simulation gun used for training in police and the like is preferably the same in operability and the like as a real gun.

For example, in a bolt rifle, a bolt handle provided in a rifle body is operated to perform loading. Such a gun or the like is provided with a cocking indicator so that whether the gun is cocked or not can be grasped in a state of the gun, and the state of the gun can be grasped visually or tactually by the cocking indicator. Conventionally, although a loading indicator is mounted on a simulation gun, the number of cases is small. However, in the simulation gun, the cocking indicator is also advantageous, and therefore the present applicant has advanced its development and has made the present invention.

As a result of examining the prior art, Japanese patent application laid-open No. 2004-347221 was found. The present invention relates to a shooting mechanism of a toy gun capable of judging whether a shooting state or a non-shooting state is possible or impossible from the appearance, and a rod-shaped member such as an indicator bar penetrating a piston cylinder mechanism in the front and rear direction is used. In the cocked state, the front end of the indicator strip abuts against the piston, and therefore, the indicator strip is prevented from moving forward, and at this time, the rear end of the indicator strip protrudes to the outside and becomes visible, and therefore, the indicator strip has to be longer and larger than the piston cylinder mechanism.

Such a long and large rod-like member is required as the indicator, and assembling this to the gun body causes complication of the structure. Further, the mechanism for moving the front and rear may cause a problem in strength due to a defect that a frictional resistance is generated in a sliding portion with the through-hole. Further, the rod-shaped indicator is biased forward by the spring when the piston is loaded, and therefore acts in a direction to increase the thrust of the piston. As a result, it is predicted that there will be a problem that an excessive energy is applied to the bullet or the piston operation will be unstable.

Disclosure of Invention

Technical problem to be solved by the invention

The present invention has been made in view of the above-described points, and an object thereof is to clearly grasp the charging state only by an operation member independent of the piston cylinder mechanism. Another object of the present invention is to provide a cocking indicator for a compact simulation gun.

Means for solving the technical problem

In order to solve the above problem, the present invention provides a simulation gun that performs loading by operating an operation member provided in a gun body, the simulation gun including: an indicator disposed at a rear portion of the operation member, and configured such that a part thereof can be moved in and out of the operation member in response to a cocking operation of the operation member; a lock member that is locked to the indicator so as to maintain the protruding state when a part of the indicator protrudes from the operation member, and a release mechanism that sets the protruding state of the indicator to a non-protruding state.

The invention provides a loading indicating device in a simulation gun, which comprises an operating member, an indicator, a locking member, a releasing mechanism and the like. Here, it is important to provide an indicator disposed at the rear of the operation member, and a part of the indicator is configured to be able to move in and out of the operation member in response to the cocking operation of the operation member.

The cocking indicator of the present invention may be any indicator. That is, as the indicator, not only the long and large rod-shaped member as described in the above patent document is not necessary, but also an indicator having a shape and a configuration suitable for a simulation gun can be designed.

In the present invention, the indicator can take 3 different states as follows: a pre-cocked state in which a portion thereof is recessed more than a rear portion of the operating member; a state in which a part of the indicator is located in the breech at substantially the same position as the rear portion of the operating member, and a state in which a part of the indicator protrudes from the rear portion of the operating member.

From the viewpoint of grasping the loading state, it is sufficient to know whether or not loading has been performed, and for example, any 2 states such as access are sufficient. Thus, claim 1 clearly includes the indicating device having this structure. However, it is sometimes necessary to grasp whether or not the loading operation is in the middle, and in order to grasp this state, it is necessary to show that the loading operation is in an intermediate state other than the in-and-out state.

In the present invention, it is preferable that the release mechanism includes a sear, the sear is operated to the lock member in conjunction with a trigger for a firing operation, the locking of the indicator is released to set a non-protruding state, and the lock member is released from the engagement state of the engagement mechanism by the sear.

The indicator indicates a change in the cocking state, and the cocking is completed by the end of the firing of the bullet or the end of the firing operation (so-called blank fire), and generally, the firing operation is configured to pass through a process of being transmitted from the trigger via the sear. Therefore, it is a significant structure to associate the locking of the indicator with the sear.

In the simulation gun according to the present invention, the operation member is preferably configured to be loaded by operating an operation member provided in the gun body, and the operation member includes: a piston cylinder mechanism provided movably in the forward and backward directions with respect to the gun body; a bolt member integrally attached to a rear portion of the piston cylinder mechanism, and an operation handle portion provided between the piston cylinder mechanism and the bolt member, the bolt member having a hollow portion opened rearward and having a spring member disposed in the hollow portion and protruding from the operation member by a cocking operation of the operation member, the indicator being movable forward and backward in the hollow portion and having a part thereof urged in a direction in which the bolt member moves forward, the cocking indicator device having a lock member locked to the indicator provided to the gun body in order to hold the indicator in a state in which the indicator protrudes from the hollow portion of the bolt member, the cocking indicator device having a release mechanism having a sear which is set in a non-protruding state in order to act on the lock member in the protruding state and which acts on the lock member in conjunction with the trigger to release the locking of the indicator, thereby setting the state of non-protrusion.

Effects of the invention

The present invention is configured and functions as described above, and therefore, the present invention exhibits an effect that the present invention can be incorporated into an operation member independent of the piston cylinder mechanism to clearly grasp the charging state. Further, according to the present invention, it is possible to provide a cocking indicator in a simulation gun suitable for miniaturization by being assembled to a part of an operation member.

Detailed Description

The present invention will be described in more detail below with reference to the illustrated embodiments. The simulation gun 10 according to the present invention shown in the embodiment is a bolt rifle as a prototype, and is roughly divided into a firing device unit 11 assembled to a gun body, a barrel unit 12 positioned in front of the firing device unit 11, and a butt unit 13 positioned in rear of the firing device unit 11.

The launcher 11 includes a piston 14 and a cylinder 16, and includes: the operation member 20 includes a cylinder mechanism 15 for generating compressed air to fire a bullet, a firing mechanism 25 for performing a firing operation by a trigger 22 described later, and a bullet loading mechanism 35. The piston cylinder mechanism 15 has a piston 14 and a cylinder 16, is movably attached in the front-rear direction of the gun body, and constitutes the front part of an operation member 20 for cocking. On the rear side of the piston cylinder mechanism 15, a bolt member 21 is provided as will be described later, and the bolt member 21 constitutes the rear portion of the operating member 20.

An operating member 20 including a piston cylinder mechanism 15 and a bolt member 21 is movable in the front-rear direction of the gun body, and an operating handle 17 is provided on the bolt member side to operate the operating member 20. The operating handle portion 17 includes an operating lever 17c having a shape and a structure that imitate a member of a bolt handle provided in a bolt rifle. In fig. 1, 2, and the like, the operating lever 17c of the operating handle portion 17 is indicated by a two-dot chain line because the transmitter portion is not visible in the illustrated state, and therefore only the installation position is illustrated.

The structure 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 the normal structure, and therefore, a detailed description thereof will be omitted. That is, the piston-cylinder mechanism 15 includes a piston spring 18 that is pressurized by the retraction of the piston 14 inserted into the cylinder 16 and releases the pressurized piston to advance the piston 14. The cylinder 16 is assembled to the gun body so as to be able to advance and retreat, and is configured to open a space for raising the bullet B at the front of the nozzle 19 at the front end when retreating, and to load the bullet B to the loading portion at the rear end of the barrel through the front end of the nozzle 19 when advancing.

The firing mechanism 25, which serves as a firing operation as described above, has the trigger 22 pivotally supported on the gun body side by the fulcrum shaft 22a in a rotatable manner, and is urged by the trigger spring 22 b. The trigger 22 has an input portion 22c protruding so as to come into contact with the intermediate member 23 on the front side, and a trigger screw 22d for adjusting the amount of protrusion from the intermediate member 23 on the rear side. The intermediate member 23 is pivotally supported on the gun body side by a support shaft 23a, and transmits the operation of the trigger 22 to the 1 st sear 24 in the sear including 2 members (see fig. 3). The 1 st sear 24 is pivotally supported on the gun body side rotatably by a front support shaft 24a, and springs 23b, 24b act on the intermediate member 23 and the 1 st sear 24, respectively. The 1 st sear 24 has an engaging portion 33 at the rear, and is configured to be locked in this state by being engaged with an engagement target portion 34 of an indicator lock 32 acting on an indicator 30 described later.

The 1 st sear 24 is pivotally supported by the 2 nd sear 27 through a support shaft 27a in a rotatable manner, and the 2 nd sear 27 is urged to project in the direction of the piston 14 by a sear spring 27 b. On the other hand, an engaging portion 28 is provided at the rear portion of the piston 14, and is configured to engage with a protruding tip 29 of the 2 nd choke bar 27 at the piston retreating position (see fig. 6B). A slit 16a through which the tip 29 passes is formed along the longitudinal direction of the lower surface of the cylinder 16 so as to engage with the piston 14.

As described above, the intermediate member 23 is pivotally supported by the gun body side at the lower portion, and is locked to the locking target portion 26 formed at the rear portion of the 1 st sear 24 by the locking portion 23c formed at the upper portion (see fig. 3). The intermediate member 23 has a rod length arbitrarily set between the support shaft 23a and the locking portion 23c, and the input portion 22c of the trigger 22 is in contact with a position of about half of the rod length in the embodiment.

The operating knob portion 17 described above is located between the bolt member 21 and the piston-cylinder mechanism 15 as a part of the operating member 20, and the operating knob portion 17 is provided so as to be rotatable about a longitudinal axis with respect to the piston-cylinder mechanism 15 (see fig. 4A to 4C, etc.). The operating handle 17 is configured to be able to rotate the operating lever 17C from a lower position shown in fig. 4A to 4C to an upper position shown in fig. 5A to 5C for cocking operation.

The operating handle portion 17 is located below the operating lever 17c, and a part 30a of an indicator 30 described later is engaged with a recess 17a on the operating handle portion side. At a position above the operating lever 17c, a convex portion 17b provided to be able to move forward and backward to the front side of the operating handle portion 17 is engaged with a concave portion 15b provided at the rear portion of the piston cylinder mechanism 15. With this engagement mechanism, the operating lever 17c of the operating handle portion 17 is positioned at the lower position and the upper position, respectively.

The indicator 30 is assembled to the hollow portion 21a of the bolt member 21 so as to be movable forward and backward, and is urged forward, that is, in a direction recessed from the hollow portion 21a, by an indicator spring 31 disposed between the bolt member side receiving portion 21b and the indicator side receiving portion 30 b. As is apparent from fig. 4A and 4C, the recess 17a on the operation knob portion side is in a state engageable with the portion 30a of the indicator 30 only when the operating lever 17C of the operation knob portion 17 is located at the lower position. The portion 30a of the indicator 30 protrudes slightly downward from the portion in front of the indicator, and functions to prevent the indicator lock 32 from being lifted when not in operation and to prevent the indicator 30 from moving forward when loaded.

The recess 17a on the operation handle portion side also serves as a portion into which the indicator lock 32 enters to hold the indicator 30 in a protruding state. The indicator lock 32 constitutes a lock member for holding the indicator 30 in a projecting state, is assembled to the gun body side of the rear end portion of the 1 st sear 24 (see fig. 3), and is biased upward by a lock spring 32b so that the front end portion 32a enters the recess 17 a. The front end portion 32a of the indicator lock 32 protrudes upward from the through hole 32c on the gun body side.

As the engaging mechanism with the 1 st sear 24, an engaging portion 33 on the 1 st sear 24 side is provided with an indicator lock 32 as an engaging target portion 34. The engaging portion 33 on the 1 st sear 24 side is engaged with the engaging portion 34 of the indicator lock 32 to define the upward movement limit, and is lowered by the rotation of the 1 st sear 24 to pull out the indicator lock 32 from the indicator 30 side to release the lock. The engaging portion 33 on the 1 st sear 24 side and the engagement target portion 34 of the pointer lock 32 constitute a release mechanism for setting the protruding state of the pointer to the non-protruding state.

The bullet loading mechanism 35 as described above is a part of the artificial gun 10, and is illustrated as a magazine 37 that is detachably mounted in a magazine slot 36 provided on the gun body side. The bullet B is urged forward by the magazine spring 38 from a state filled in the magazine 37, and is fed to a position rearward of the barrel by the bullet feed section 39.

The operation of the loading indicating device in the simulation gun according to the present invention configured as described above will be described with reference to fig. 6A to 6B. Fig. 6A shows a state in which the cocking operation is not performed, and a state in which the lever 17C is positioned at the lower position and a part 30a of the indicator 30 is engaged with the recess 17a (fig. 4A to 4C). At this time, the indicator 30 is biased by the indicator spring 31 to be positioned at the front position, and the rear end enters the hollow portion 21a of the bolt member 21.

Although the indicator 30 in the submerged state cannot be seen from the side, the user can see that the indicator 30 is recessed into the hollow portion 21a of the bolt member 21 when the user touches the indicator with the fingertip. Thus, it can be confirmed that the gun is not loaded, and even if the trigger 22 is operated, the gun is in a safe state without any change. The tactile-sense-based judgment can be made, which is also effective when the indicator 30 is not visible or visually confirmed at no time, such as at night.

Next, when the handle lever 17C is operated to rotate to the upward position for cocking, the concave portion 17a is disengaged from the portion 30a of the indicator 30, and the convex portion 17b is engaged with the concave portion 15b of the piston cylinder mechanism 15 (fig. 5A to 5C). As a result, the operating lever 17c is held at the upper position, and therefore the operating member 20 can be sufficiently latched rearward in a stable manner.

In the piston cylinder mechanism 15, the engagement portion 28 of the retreated piston 14 and the tip 29 of the 2 nd choke 27 are in an engaged state (fig. 6B). Thereby, the part 30a of the indicator 30 is separated from the concave portion 17a, and is brought into contact with the rear surface of the operation grip portion 17 to move rearward. At this time, the indicator 30 is in a state of being flush with the bolt member 21, and the flush state can be easily confirmed visually or by touch. Then, as the cylinder 16 retreats, the indicator lock 32 is raised to a position contacting the cylinder 16 by the lock spring 32 b. When the bullet B is positioned at the bullet supply portion 39, the cylinder 16 moves backward to a position rearward of the barrel.

Then, the operating member 20 is pushed forward until the operating lever 17c is stopped, thereby performing cocking. In the state of fig. 7A, the piston 14 of the piston-cylinder mechanism 15 is engaged with the tip 29 of the 2 nd choke 27. Then, the operating lever 17c returns to the lower position, and the recessed portion 17a comes to the upper position of the indicator lock 32, so that the tip portion 32a rises and can be engaged. Further, the cartridge B is loaded into the loading portion through the nozzle 19 at the tip by the advance of the cylinder 16.

As the operating member 20 moves forward, the portion 30a of the indicator 30 engages with the front end portion 32a of the indicator lock 32 that is biased upward, and the advance is stopped, and as a result, the indicator 30 protrudes slightly rearward from the bolt member 21, and becomes a protruding state. The indicator 30 is projected to clearly grasp the loaded state visually and tactually.

When the trigger 22 is operated in a state in which the cocking is completed, the piston spring 18 is operated, compressed air is generated by the advance of the piston 14, and the bullet B is shot by the generated compressed air (fig. 7B). In the striking mechanism 25, the rear end portion of the 1 st sear 24 descends in conjunction with the operation of the trigger 22, and further, the engagement portion 33 provided at the rear end portion descends to engage with the engagement target portion 34 of the indicator lock 32, and the indicator lock 32 is pressed, and as a result, the indicator 30 advances by the indicator spring 31, and returns to the state of being recessed in the hollow portion 21a of the bolt member 21.

Fig. 8 shows a state of no action after the bullet B is fired, and is a state in which the indicator 30 is depressed and the cocking operation is not performed. That is, the state is the same as that of fig. 6A, and the joystick 17c is moved to the lower position, thereby returning to the initial state. As described above, according to the present invention, the 3 rd state which is not the entry/exit state is taken in addition to the 2 protruding/recessed states, and therefore, the user can clearly grasp the states before, during, and after the operation of the loading.

The indicating device of the present invention can be compactly incorporated in a simulation gun as an extremely small indicator, and therefore, even if a long simulation gun such as a rifle is cocked, the indicating device can be implemented without significantly changing the internal structure of the simulation gun. Thus, the present invention can be applied not only to a rifle type simulation gun but also to a pistol type simulation gun, for example, with ease.
