[0009] Hereinafter, embodiments of the present invention will be described in detail 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.

[0010] [First embodiment] A toy gun 100 according to a first embodiment of the present invention will be described with reference to Fig. 1. The toy gun 100 is a gas blowback toy gun.

[0011] As shown in FIG. 1, the toy gun 100 includes a slide 101, a hammer 102, a hammer roller 103, and a valve knocker 104.

[0012] The slide 101 moves backward by gas pressure and then returns to the forward position (the state shown in FIG. 1).

[0013] Hammer 102 rotates in conjunction with the movement of slide 101. Hammer roller 103 is rotatably supported on hammer 102. Valve knocker 104 moves magazine valve 106 in conjunction with the rotation of hammer 102, and turns on and off the gas ejection from gas storage section 171 of magazine 107.

[0014] When the slide 101 moves backward, the hammer roller 103 comes into contact with a downward convex portion 111 that constitutes part of the slide 101 and is urged backward, causing the hammer 102 to rotate backward (clockwise in the drawing), and the hammer roller 103 itself also rotates clockwise in the drawing.

[0015] As described above, the hammer roller comes into surface contact with the slide, and as the hammer roller rotates along the surface of the slide, it also rotates the hammer itself, reducing the contact resistance between the slide and hammer and achieving extremely smooth drive.

[0016] [Second embodiment] Next, a toy gun according to a second embodiment of the present invention will be described with reference to Figure 2 onwards. Figure 2 is an external view of a gas blowback toy gun 200 according to this embodiment.

[0017] Toy gun 200 includes slide 201, grip 202, and trigger 203. When trigger 203 is pulled, gas is ejected from a magazine or a dedicated gas cylinder attached to grip 202, and the force of the gas causes a BB bullet to be fired, moving the slide backward, and the BB bullet in the magazine is loaded.

[0018] 3 is a cross-sectional view of the rear (shooter's side) of toy gun 200 as seen from the shooter's left side. Hammer 302 rotates rearward about pivot shaft 321 in conjunction with the movement of slide 201. Hammer roller 303 is supported on hammer 302 so as to be rotatable about pivot shaft 331. Valve knocker 304 moves magazine valve 306 in conjunction with the rotation of hammer 302, turning on and off the release of gas from gas storage section 371 of magazine 307.

[0019] FIG. 4 is a perspective view of the hammer roller 303, showing the overall shape from four directions. The hammer roller 303 includes a rotation shaft 331, a roller portion 432, flat portions 433 and 434 formed on the side surfaces of the roller portion 432, and regulating surfaces 435 and 436 serving as regulating means for regulating the rotation angle between the roller portion 432 and the hammer 302 to a predetermined angle. Similar regulating surfaces are also provided on the hammer 302. The hammer roller 303 rotates by approximately 60 degrees, which is the angle between the regulating surfaces 435 and 436. The flat portion 434 is formed larger than the flat portion 433.

[0020] FIG. 5 shows a state in which, from the state shown in FIG. 3, trigger 203 is pulled, causing a trigger bar (not shown) to move the sear, releasing hammer 302, and hammer 302 is raised by the biasing force of spring 305. In other words, hammer 302 is raised in conjunction with trigger 203 via the sear. As hammer 302 rotates, valve knocker 304 is pushed toward magazine 307, magazine valve 306 slides, and gas is ejected from gas storage section 371 to piston 308. In a standby state in which hammer 302 is raised, restriction surfaces 435 and 436 restrict the rotation of hammer roller 303 so that flat surface 433 faces vertically. Hammer 302 is the starting point for the action of firing a bullet in conjunction with the trigger.

[0021] When the slide 201 moves back a little due to the gas pressure, as shown in FIG. 6, the flat portion 433 of the hammer roller 303 comes into contact with a downward convex portion 601 that constitutes part of the slide 201 and is urged backward. This causes the hammer 302 to rotate backward (clockwise in the figure). The downward convex portion 601 has a flat surface 611, a flat surface 612, and a curved portion 613 that connects them. When the toy gun 200 is held pointing straight ahead of the shooter, the flat surface 611 is a vertical plane and the flat surface 612 is a horizontal plane. The downward convex portion 601 is provided on the underside of the piston 308 built into the slide 201, and the rear corner of the flat surface 612 is provided with a curved portion 613 that has a large radius, and the front corner of the flat surface 612 is provided with a curved portion that has a small radius.

[0022] 7 shows a state in which slide 201 has moved further back from the state shown in FIG. 6, and hammer 302 has rotated about 30 degrees. Hammer roller 303 gradually rotates backward so that flat portion 433 of hammer roller 303 abuts against curved portion 613 of downward convex portion 601 and follows the curved surface.

[0023] Figure 8 is a partial see-through view of the rear (shooter's side) of toy gun 200 as seen from the shooter's right side in the state shown in Figure 7. In this state, sear 801 does not engage with engaging portion 802 provided on hammer 302, allowing hammer 302 to rotate freely. Sear 801 is provided to maintain the position of hammer 302 when it has rotated rearward.

[0024] 9, when slide 201 is further moved backward from the state shown in FIG. 7, hammer 302 rotates approximately 60 degrees. At this time, flat surface portion 433 of hammer roller 303 comes into contact with flat surface 612 of downward convex portion 601.

[0025] Figure 10 is a partial see-through view of the rear (shooter's side) of toy gun 200 as seen from the shooter's right side in the state shown in Figure 9. At this point, sear 801 engages with engagement portion 802 of hammer 302. Hammer 302 is configured to be able to rotate to an angle slightly larger than the angle at which it most closely engages with sear 801, preventing sear 801 from failing to engage hammer 302.

[0026] FIG. 11 is a diagram showing a state in which the slide 201 is further moved back from the state shown in FIG. The spring 305 rotates the hammer 302 so that when the slide 201 moves backward, the downward convex portion 601 comes into contact with the flat portion 433 and the hammer roller 303 is urged downward, and then moves upward after climbing over the downward convex portion 601.

[0027] Figure 12 is a partial see-through view of the rear (shooter's side) of toy gun 200 as seen from the shooter's right side in the state shown in Figure 11. As hammer roller 303 has climbed over downward convex portion 601, hammer 302, which had been tilted down excessively, has risen up until it comes into contact with sear 801.

[0028] 13 shows the state in which slide 201 has been moved back to its limit. In this state, hammer 302 attempts to move upward due to the biasing force of spring 305, and although there is clearance between hammer roller 303 and bottom surface 1311 of piston 308, the rotation is restricted by sear 801, and hammer 302 remains stationary.

[0029] When the hammer 302 is held by the shear 801, the distance from the rotation axis 331 of the hammer roller 303 to the flat surface 433 is shorter than the vertical distance from the rotation axis 331 to the bottom surface 1311, which serves as the front lower surface. Therefore, when the slide 201 is near the rearmost position, it does not come into contact with the hammer roller 303 at all, and the hammer roller 303 moves smoothly.

[0030] Figure 14 is a diagram showing a state in which slide 201 has advanced from the state in Figure 13. As slide 201 advances, flat surface 434 of hammer roller 303 comes into contact with the front portion of downward convex portion 601 and is urged forward, causing hammer roller 303 to rotate. Meanwhile, the rotation of hammer 302 is restricted by shear 801, and hammer 302 is in a stationary state. Here, the distance from pivot shaft 331 of hammer roller 303 to flat surface 433 is greater than the shortest distance from pivot shaft 331 to downward convex portion 601 when hammer 302 is held by shear 801.

[0031] Figure 15 is a diagram showing a state in which hammer roller 303 has further rotated forward from the state shown in Figure 14. As slide 201 moves forward, flat surface 434 of hammer roller 303 comes into contact with downward convex portion 601 and is urged forward, causing hammer roller 303 to rotate. Meanwhile, the rotation of hammer 302 is restricted by shear 801, and the hammer 302 is in a stationary state.

[0032] Figure 16 is a diagram showing a state in which the hammer roller 303 has rotated further forward from the state in Figure 15. When the hammer roller 303 rotates to the state in Figure 16, a clearance is created between the hammer roller 303 and the downward convex portion 601, and the slide 201 moves forward smoothly.

[0033] In other words, the distance from the rotation axis 331 of the hammer roller 303 to the flat portion 434 is shorter than the shortest distance from the rotation axis 331 to the convex portion 601 of the slide 201 when the hammer 302 is locked to the shear 801 as shown in FIG.

[0034] When the slide 201 moves further forward from the state shown in FIG. 16, it returns to the state shown in FIG. 3, and the sear 801 locks the hammer 302 and goes into a standby state until the trigger 203 is pulled again.

[0035] As described above, according to this embodiment, when the downward convex portion rotates the hammer roller, no force is required to move the hammer, so there is no large resistance and the movement is smooth.

[0036] [Third embodiment] Next, a hammer roller according to a third embodiment of the present invention will be described with reference to Figure 17. Figure 17 is a diagram illustrating the appearance of a hammer roller 1701 according to this embodiment. Hammer roller 1701 according to this embodiment differs from the second embodiment in that it has concave portions 1733 and 1734 instead of flat portions. Other configurations and operations are similar to those of the second embodiment, so the same configurations and operations are denoted by the same reference numerals and detailed description thereof will be omitted.

[0037] 17 is a front view of roller portion 1732 of hammer roller 1701. Here, two concave portions 1733 and 1734 are provided, but either one may be a flat portion.

[0038] [Other embodiments] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments. Various modifications can be made to the configuration and details of the present invention that are understandable to those skilled in the art within the technical scope of the present invention. Furthermore, any combination of the separate features included in each embodiment is also included in the technical scope of the present invention.
