BEST MODE FOR CARRYING OUT THE INVENTION Exemplary embodiments of the present invention will be described in detail below with reference to the drawings. However, the components described in the following embodiments are merely examples, and the technical scope of the present invention is not limited to them.

[First Embodiment]
A muzzle device 100 according to a first embodiment of the present invention will now be described with reference to FIGS. 1-8. FIG. 1 is a schematic perspective view showing an outline of a muzzle portion 150 and a muzzle attachment component 100. FIG. The muzzle mount component 100 can be any component that attaches to the muzzle 150 . For example, a suppressor that has a silence function, a flash hider that has a function to hide sparks in a real gun, a muzzle brake that has a recoil reduction function in a real gun, and a glowing BB bullet. A full auto tracer with a function is included.

A tip portion 152 of the muzzle portion 150 has a thin cylindrical shape. Three projections 151 based on the three lug (three lug or tri lug) standard that allow the muzzle attachment part 100 to be attached with one touch (push in and rotate 60 degrees) are located at a predetermined distance from the tip portion 152 of the muzzle 150. is provided on the outer peripheral surface. However, the present invention is not limited to the three lug standard and may be a two lug or four lug or other standard adapter configuration as long as the mechanism is push-fit.

FIG. 2 is an external view showing the detailed configuration of the muzzle part 150 and the muzzle attachment part 100. FIG. The muzzle attachment component 100 is configured by screwing together a functional component 202 having, for example, a muffling function and an adapter component 201 . Further, the muzzle portion 150 of this embodiment is integrally configured with a front sight 251 having a blade (not shown) for aiming. However, the invention is not limited to this. That is, the muzzle portion 150 may be provided separately from the front sight 251, or may be provided integrally with the outer barrel.

In a state 210 in which the muzzle part 150 is inserted into the adapter part 201 and pushed in, the outer peripheral part of the adapter part 201 is separated from the functional part 202 and contacts the muzzle part 150 side. In this state, when the outer peripheral portion of the adapter part 201 is rotated by a predetermined angle (here, 60 degrees) and then released, the adapter part 201 returns to the functional part 202 side, and the muzzle attachment part 100 is firmly fixed to the muzzle part 150. State 220 is reached.

FIG. 3 is a cross-sectional view showing the internal configuration of the muzzle part 150 and the muzzle attachment component 100. As shown in FIG. The adapter part 201 of the muzzle-mounted part 100 comprises tubular parts 301, 302 and a spring 303 as a biasing member.
The tubular part 302 contacts the muzzle part 150 and contributes to the positioning of the functional part 202 . The tubular part 301 is slidable with respect to the tubular part 302 and the muzzle 150 can be fitted with a locking mechanism. The spring 303 urges the tubular part 302 toward the tubular part 301 so that the convex part 151 of the lock mechanism and the tubular part 301 are fixed in an engaged state.

A screw 321 for screwing with the functional component 202 is provided in front of the cylindrical component 302 (shooting direction). Here, a configuration in which the functional component 202 is screwed to the cylindrical component 302 will be described, but the present invention is not limited to this. It may be pinned. Also, the functional component 202 and the cylindrical component 302 may be integrally formed.

The tubular part 301 constitutes the outer periphery of the adapter part 201, and includes a housing member 311 that houses the tubular part 302 and the spring 303, and a sealing member that seals the opening on the front side (shooting direction side) of the housing member 311. A stop member 312 and a screw 313 for fixing the sealing member 312 to the housing member 311 are provided.

The tubular part 302 is housed inside the tubular part 301 so as to be slidable in the front-rear direction (direction along the axis of the muzzle).

The cylindrical part 302 is in contact with the shooter's side end of the spring 303 and is biased rearward (in the shooter's direction) by the spring 303 . As a result, the end face 322 of the cylindrical part 302 on the side opposite to the screw 321 is in contact with the contact surface 314 provided inside the housing member 311 .

FIG. 4 shows the muzzle 150 inserted into the rear opening 315 of the tubular part 301, and the tubular part 301 urged rearward (shooter's direction) away from the functional part 202. FIG. 401 is a front view from the side and 402 is a section AA. The end surface 322 is separated from the contact surface 314 by urging the cylindrical part 301 toward the shooter (gun body side) against the urging force of the spring 303 . A tubular elastic part 421 is attached to the inner surface of the tubular part 302, so that the tip part 152 of the muzzle part 150 can be inserted into the tubular part 302 without damaging it.

FIG. 5 is a front view 501 from the muzzle side showing a state in which the tubular part 301 is further rotated 60 degrees counterclockwise as viewed from the muzzle side while being biased toward the muzzle portion 150 from the state shown in FIG. and AA sectional view 502. FIG. By rotating by 60 degrees, the claw 516 provided on the cylindrical part 301 faces the rear side (shooter side) of the projection 151 .

In FIG. 6, when the tubular part 301 is released in the state of FIG. 601 is a front view 601 from the muzzle side and a cross-sectional view 602 taken along line A--A showing a state in which the lens is pressed.

The claw 516 abuts on the convex portion 151 to firmly fix the muzzle attachment component 100 to the muzzle portion 150 .

Also, at this time, the outer peripheral surface of the tip portion 152 of the muzzle portion 150 is firmly held and positioned by the inner peripheral surface 621 of the tubular part 302 . on the other hand. The outer peripheral surface of the convex portion 151 of the muzzle portion 150 is also firmly held and positioned by the inner peripheral surface 622 of the tubular part 302 .

As a result, relative to the muzzle 150, the tubular part 302 is positioned very precisely, avoiding accumulation of dimensional tolerances, resulting in a function screwed onto the threads 321 of the tubular part 302. The component 202 is also precisely mounted and centered on the muzzle 150 without wobbling.

FIG. 7 is a diagram showing changes in the BB cross-sectional view of FIG. It can be seen that as the cylindrical part 301 rotates, the configuration facing the convex portion 151 of the muzzle changes from the notch 701 to the claw 516 . That is, when inserting the muzzle portion 150 into the muzzle mounting component 100, three projections 151 are inserted into the three notches 701, and then the adapter component 201 is pushed toward the muzzle portion 150 and turned. The three claw portions 516 are engaged with the three protrusions 151 so as to face each other.
The tubular part 301 has three dead ends 702 extending axially from the inner peripheral surface. Since the protrusion 151 abuts against the stop portion 702, the rotation of the cylindrical part 301 (counterclockwise when attached and clockwise when detached) can be limited to a certain range. It is possible to prevent the attachment/detachment operation from becoming unreliable due to overshoot during rotation. The dead end portion 702 is not an essential configuration, and as shown in FIG. 8, the dead end portion 702 may not be formed. In that case, there is an effect that it can be rotated in either direction when it is attached or detached.

Therefore, the muzzle attachment part 100 can be attached to the muzzle part 150 without rattling while maintaining the functionality of being able to attach and detach the muzzle attachment part 100 easily. It is possible to maintain a high bullet firing accuracy. Furthermore, by improving the firing accuracy, it is possible to prevent the bullet from hitting the internal mechanism and damaging the functional parts and the BB bullet.
