Modes for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be exemplarily and specifically described with reference to the drawings. However, the components described in the following embodiments are merely examples, and are not intended to limit the technical scope of the present invention thereto.

[0010] [First Embodiment] The muzzle device 100 as the first embodiment of the present invention will be described with reference to FIGS. 1 to 8. FIG. 1 is a schematic perspective view showing an overview of the muzzle portion 150 and the muzzle device 100. The muzzle device 100 may be any component as long as it can be attached to the muzzle portion 150. For example, it includes a Suppressor having a silencing function, a Flach Hider having a function of hiding sparks in a real gun, a Muzzle Brake having a function of reducing recoil in a real gun, a Fullauto Tracer having a function of making a glow-in-the-dark BB bullet glow, and the like.

[0011] The tip portion 152 of the muzzle portion 150 has a thin-walled cylindrical shape. At a position separated from the tip portion 152 of the muzzle portion 150 by a predetermined distance, three convex portions 151 based on a three lug (or tri lug) standard that allows the muzzle device 100 to be attached with one touch (pushed in and rotated 60 degrees) are provided on the outer peripheral surface. However, the present invention is not limited to the three lug standard, and may have an adapter shape with two lug, four lug, or other standards as long as it is a mechanism for pushing in and attaching.

[0012] FIG. 2 is an external view showing the detailed configuration of the muzzle portion 150 and the muzzle device 100. The muzzle device 100 is configured by screwing together, for example, a functional component 202 having a silencing function and an adapter component 201. Further, the muzzle portion 150 of the present embodiment is integrally configured with a front sight 251 having a blade (not shown) for aiming. However, the present invention is not limited thereto. That is, the muzzle portion 150 may be provided separately from the front sight 251, or may be provided integrally with the outer barrel.

[0013] In the state 210 where the muzzle part 150 is inserted into and pushed into the adapter part 201, the outer peripheral part of the adapter part 201 is separated from the functional part 202 and abuts on the muzzle part 150 side. When the outer peripheral part of the adapter part 201 is rotated by a predetermined angle (here, 60 degrees) and then released in this state, the adapter part 201 returns to the functional part 202 side, and the muzzle mounting part 100 is in a state 220 where it is firmly fixed to the muzzle part 150.

[0014] Figure 3 is a cross-sectional view showing the internal structure of the muzzle part 150 and the muzzle mounting part 100. The adapter part 201 of the muzzle mounting part 100 includes cylindrical parts 301, 302 and a spring 303 as a biasing member. The cylindrical part 302 is in contact with the muzzle part 150 and contributes to the positioning of the functional part 202. The cylindrical part 301 is slidable with respect to the cylindrical part 302, and the muzzle part 150 can be fitted by a locking mechanism. The spring 303 biases the cylindrical part 302 in the direction of the cylindrical part 301 so as to be fixed in a state where the convex part 151 of the locking mechanism and the cylindrical part 301 are engaged.

[0015] A screw 321 for screwing with the functional part 202 is provided in front of the cylindrical part 302 (in the firing direction). Here, a configuration where the functional part 202 is screwed to the cylindrical part 302 will be described, but the present invention is not limited to this, and the functional part 202 may be adhered or pinned to the cylindrical part 302. Also, the functional part 202 and the cylindrical part 302 may be integrally formed.

[0016] The cylindrical part 301 constitutes the outer peripheral part of the adapter part 201, and includes a housing member 311 that houses the cylindrical part 302 and the spring 303, a sealing member 312 that seals the opening on the front side (firing direction side) of the housing member 311, and a screw 313 that fixes the sealing member 312 to the housing member 311.

[0017] The cylindrical part 302 is housed inside the cylindrical part 301 so as to be slidable in the front-rear direction (the direction along the axis of the muzzle).

[0018] The cylindrical component 302 abuts against the shooter-side end of the spring 303 and is biased rearward (towards the shooter) by the spring 303. As a result, the end face 322 on the side opposite to the screw 321 of the cylindrical component 302 abuts against the abutment surface 314 provided inside the housing member 311.

[0019] Figure 4 is a front view 401 and an A-A cross-sectional view 402 from the muzzle side showing a state where the muzzle portion 150 is inserted into the rear-side opening 315 of the cylindrical component 301 and the cylindrical component 301 is further biased rearward (towards the shooter) so as to be separated from the functional component 202. By biasing the cylindrical component 301 against the biasing force of the spring 303 towards the shooter side (the gun body side), the end face 322 is separated from the abutment surface 314. A cylindrical elastic portion 421 is attached to the inner surface of the cylindrical component 302, so that the tip portion 152 of the muzzle portion 150 can be inserted into the cylindrical component 302 without being damaged.

[0020] Figure 5 is a front view 501 and an A-A cross-sectional view 502 from the muzzle side showing a state where, from the state of Figure 4, the cylindrical component 301 is further rotated counterclockwise by 60 degrees as viewed from the muzzle side while being biased towards the muzzle portion 150 side. By rotating by 60 degrees, the claw 516 provided on the cylindrical component 301 comes to face a position on the rear side (shooter side) of the convex portion 151.

[0021] Figure 6 is a front view 601 and an A-A cross-sectional view 602 from the muzzle side showing a state where, when the hand is released from the cylindrical component 301 in the state of Figure 5, the cylindrical component 301 moves forward (in the firing direction) due to the elastic force of the spring 303 and abuts against the functional component 202.

[0022] When the claw 516 abuts against the convex portion 151, the muzzle mounting component 100 is firmly fixed to the muzzle portion 150.

[0023] 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 cylindrical component 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 cylindrical component 302.

[0024] As a result, with respect to the muzzle portion 150, the cylindrical component 302 is positioned very accurately while avoiding the accumulation of dimensional tolerances. As a result, the functional component 202 screwed onto the screw 321 of the cylindrical component 302 is also accurately attached to the muzzle portion 150 without wobbling and can be centered.

[0025] FIG. 7 is a view showing a change in the B-B cross-sectional view of FIG. 2. It can be seen that when the cylindrical component 301 rotates, the configuration facing the convex portion 151 of the muzzle portion changes from the notch 701 to the claw 516. That is, when inserting the muzzle portion 150 into the muzzle mounting component 100, insert the three convex portions 151 into the three notches 701, and then push the adapter component 201 toward the muzzle portion 150 and turn it, so that the three claw portions 516 face the three convex portions 151 and are locked. The cylindrical component 301 is provided with three stop portions 702 extending axially from the inner peripheral surface. By the convex portion 151 abutting against the stop portion 702, the rotation of the cylindrical component 301 (counterclockwise during mounting and clockwise during detachment) can be restricted within a certain range. It is possible to prevent the detachment operation from becoming uncertain due to excessive rotation during rotation. The stop portion 702 is not an essential configuration, and as shown in FIG. 8, a configuration without forming the stop portion 702 may be used. In that case, there is an effect that it may be rotated in either direction during mounting and detachment.

[0026] Therefore, while maintaining the functionality of the muzzle mounting component 100 being easily detachable, the muzzle mounting component 100 can be mounted on the muzzle portion 150 without rattling, and even when the functional component 202 is mounted, it is possible to maintain a high firing accuracy of the BB bullets fired from the muzzle portion 150. Furthermore, by improving the firing accuracy, it is possible to prevent the bullets from hitting the internal mechanism and damaging the functional components and BB bullets.

[0027] [Other Embodiments] Although the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the technical scope of the present invention. In addition, systems or devices in which the separate features included in each embodiment are combined in any manner are also included in the technical scope of the present invention.

[0028] Further, the present invention may be applied to a system composed of a plurality of devices or to a single device.
