Mode for Carrying Out the Invention

[0011] Hereinafter, with reference to the drawings, embodiments of the present invention will be exemplarily described in detail. 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.

[0012] [First Embodiment] The toy gun 100 as the first embodiment of the present invention will be described with reference to FIG. 1.

[0013] As shown in FIG. 1, the toy gun 100 according to the present embodiment includes an inner barrel 101, a hop generation unit 102, and a hop-up adjustment unit 103.

[0014] The inner barrel 101 is a cylindrical member through which the fired bullet 130 passes, and has a joint portion 111 for connecting the hop generation unit 102 at its rear end (user side end).

[0015] The hop generation unit 102 is a component having a protruding portion 121 that abuts against the bullet 130 in the inner barrel 101 and applies a frictional force.

[0016] The hop generation unit 102 is disposed between the inner barrel 101 and the nozzle 120. The bullet 130 is fired by the pressure of the gas ejected from the nozzle 120 and rotates due to the frictional force with the protruding portion 121.

[0017] The hop-up adjustment unit 103 can be biased against the hop generation unit 102 at a position close to the protruding portion 121. By changing the biasing region 122 in the hop generation unit 102, the frictional force exerted by the protruding portion 121 on the spring 130 can be adjusted. By changing the frictional force applied to the spring 130, the rotational speed in the direction of arrow 140 changes, and as a result, the ballistic trajectory and flight distance can be adjusted.

[0018] The hop generation unit 102 is a cylindrical member disposed at the rear end (user side end) of the inner barrel 101. The protruding portion 121 protrudes downward from the upper inner surface of the cylindrical member and abuts against the spring 130.

[0019] The hop-up adjustment unit 103 is a component having a contact portion 131 that contacts the hop generation unit 102. When the hop-up adjustment unit 103 slides back and forth or left and right with respect to the hop generation unit 102, the biasing region 122 in the hop generation unit 102 changes, and the degree of deformation when the protruding portion 121 is pressed against the spring 130 changes, so that the frictional force applied to the spring 130 can be adjusted.

[0020] Here, in the present embodiment, the hop generation unit 102 is made of an elastic member, but its shape does not change depending on the position of the hop-up adjustment unit 103. By changing the resistance force against the pressing force received from the spring 130, the frictional force applied to the spring 130 changes as a result. Since the protruding portion 121 has cushioning properties, it can give a constant rotational speed without depending on a slight difference in the size of the spring, and the hop-up can be stabilized.

[0021] The hop-up adjustment unit 103 includes a clip portion 132 that clips onto the outer peripheral surface of the inner barrel 101.

[0022] Figure 2 is a perspective view of the hop-up adjustment unit 103. The hop-up adjustment unit 103 includes a bridge 233 between the contact portion 131 and the clip portion 132.

[0023] FIG. 3 is a cross-sectional view showing a state in which the hop-up adjustment unit 103 is slid forward (toward the muzzle side of the toy gun) from the position shown in FIG. 1.

[0024] When the hop-up adjustment unit 103 slides forward (toward the muzzle side of the toy gun) with respect to the hop generation unit 102, in the hop generation unit 102, the biasing region 322 assumes the position shown in the figure. As a result, the degree of deformation when the protruding portion 121 is pressed against the bullet 130 becomes smaller, and the frictional force applied to the bullet 130 becomes larger. Consequently, a larger rotational speed can be imparted to the bullet 130.

[0025] FIG. 4 is a cross-sectional view showing a state in which the hop-up adjustment unit 103 is further slid forward (toward the muzzle side of the toy gun) from the position shown in FIG. 3.

[0026] When the hop-up adjustment unit 103 slides further forward with respect to the hop generation unit 102, in the hop generation unit 102, the biasing region 422 assumes the forward position shown in the figure (directly above the protruding portion 121). As a result, the degree of deformation when the protruding portion 121 is pressed against the bullet 130 becomes even smaller, and the frictional force applied to the bullet 130 becomes larger. Consequently, a larger rotational speed can be imparted to the bullet 130.

[0027] In the present embodiment, the hop generation unit 102 is attached between the rear end (user side end) of the inner barrel 101 and the nozzle 120, but the present invention is not limited thereto.

[0028] Also, in the present embodiment, the hop-up is adjusted by sliding the hop-up adjustment unit 103 back and forth, but the present invention is not limited thereto. By rotating the hop-up adjustment unit 103 left and right along the inner barrel 101, the area of the biasing region that biases the hop generation unit 102 may be changed, and consequently, the frictional force applied to the bullet 130 may be adjusted.

[0029] According to the configuration of the present embodiment, hop-up adjustment can be achieved with a very small number of parts. As a result, even a small-sized gun that originally has a large space constraint can perform hop-up adjustment. For example, in many conventional small-sized guns, since a plurality of parts cannot be mounted, they have a fixed hop-up, but in that case, it depends on the molded product, and there are individual differences and lot differences in the hop-up amount. And there was a problem that if the hop-up was not performed well, the flying distance would not be achieved. Also, if the hop-up could not be adjusted, it was impossible to handle bullets with different weights. According to the present embodiment, all of these problems can be solved.

[0030] The hop-up adjustment mechanism of the present embodiment is applicable to any toy gun regardless of the power source or mechanism, such as an air cocking gun, an electric gun, or a gas gun.

[0031] The toy gun 100 may be provided with an operation part or an opening part for sliding the hop-up adjustment part 103 back and forth or left and right with respect to the hop generation part 102 from the outside of the toy gun 100.

[0032] [Second Embodiment] Next, the toy gun 500 according to the second embodiment of the present invention will be described with reference to FIG. 5. FIG. 5 is a cross-sectional view of the toy gun 500 according to the present embodiment. The toy gun 500 according to the present embodiment is different from the first embodiment in that the hop generation part 502 has an inclined surface 523. Since the other configurations and operations are the same as those of the first embodiment, the same configurations and operations are denoted by the same reference numerals and the detailed description thereof is omitted.

[0033] Since the hop generation part 502 has the inclined surface 523, when the hop-up adjustment part 103 is slid forward (towards the target of the toy gun), it is possible to apply a stronger downward biasing force to the hop generation part 502, and it is possible to apply a stronger rotational force to the bullet 130.

[0034] [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 modifications 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. Further, a system or apparatus in which the respective separate features included in each embodiment are combined in any manner is also included in the technical scope of the present invention.
