Abstract

(57) [Summary] (Modified) [Purpose] Extend the flight distance of a bullet in a toy gun. [Structure] A protrusion 4 having a rounded tip is provided in the axial direction on an upper portion of an inner wall of the barrel main body 1 having one end connected to an engine portion and the other end serving as a muzzle 3 near the engine portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a barrel for a toy gun, and more particularly to a barrel for a toy gun capable of extending the flight distance of a projectile.

[0002]

[Prior art]

 Toy guns, which are called bebby bullets and are made of spherical plastic bullets with a diameter of several millimeters and are ejected by the force of compressed air, gas, springs, etc., have become very popular in recent years, and have been loved by a large number of people, centered around the youth.

[0003]

[Problems to be solved by the device]

 The bullets used in this type of toy gun are relatively lightweight and have low ejection energy to prevent danger, and the flight distance is short, and many users are dissatisfied with the flight distance.

It is clear that in order to increase the flight distance of a bullet, it is sufficient to eject a bullet having a large specific gravity with a strong firing output, but it is necessary to avoid giving excessive energy to the bullet from the viewpoint of danger. I had to find a safe and effective way to increase the flight distance.

The present invention is intended to solve the above-mentioned problems relating to toy guns, and does not provide a novel toy barrel that can increase the flight distance of a bullet even if it is ejected with the same ejection energy. It is what

[0006]

[Means for Solving the Problems]

 According to the invention, a toy gun is provided with a projection 4 having a rounded tip, which is attached to an upper portion of an inner wall of the barrel main body 1 having one end connected to an engine portion and the other end serving as a muzzle 3 in the vicinity of the engine portion, with its axial direction oriented. The object is to solve the above-mentioned problems by constructing a barrel for a vehicle.

[0007]

[Action]

 The spherical plastic bullet 2 is fed into the barrel body 1 from an engine section (not shown) by spring pressure, compressed air, gas pressure, etc., and moves at high speed while being accelerated toward the muzzle 3. Then, when reaching the position where the projection 4 is provided, the bullet 2 is given a rotational force in a certain direction by sliding contact with the projection 4 and jumps out from the muzzle 3. At this time, the rotating force in the clockwise direction in Fig. 1 is applied to the bullet, and as shown in Fig. 3, the interaction between the rotation and the air flow causes the upper surface of the bullet to have a low atmospheric pressure and the lower surface to have a high atmospheric pressure. The levitation force is generated due to this difference in atmospheric pressure, which increases the flight distance.

【Example】

 1 is a sectional view of an embodiment of a toy barrel according to the present invention, and FIG. 2 is a sectional view taken along the line AA in FIG.

In the figure, reference numeral 1 denotes a barrel main body made of metal or synthetic resin, having an inner diameter slightly larger than the diameter of the bullet 2, and one end thereof is connected to an unillustrated engine section (firing mechanism section). , The other end is the muzzle 3.

A protrusion 4 having a rounded tip is attached to the upper portion of the inner wall of the barrel main body 1 near the engine portion in the axial direction. It is necessary that the projecting size of the projection 4 is within a range in which the bullet 2 can pass through the inner wall.

In this embodiment, a screw hole is made in the wall surface of the barrel main body 1, and a screw having a rounded tip is screwed into the screw hole to form the protrusion 4, but it may be bonded, integrally formed, or the like. The protrusion 4 may be formed by the above means. In the method of this embodiment, the amount of protrusion of the protrusion 4 can be finely adjusted, which is very effective.

[0012]

The barrel for a toy gun according to the present invention has the above-described structure, and is accelerated by spring, air pressure, gas pressure, etc., and is moved in the barrel body 1 toward the muzzle 3 direction. The bullet 2 is given a rotational force in a fixed direction (clockwise direction in FIG. 1) by a projection 4 provided on the inner wall of the barrel body 1. Therefore, as shown in FIG. 3, the upper surface of the bullet 2 ejected from the muzzle 3 is in a low atmospheric pressure state, and the lower figure is in a high atmospheric pressure state.

In FIG. 3, reference numeral 7 indicates an air stream branched above the bullet, and 8 indicates an air stream branched below the bullet. This levitation force increases the flight distance of the bullet 2 and causes it to fly farther than a bullet ejected with the same ejection energy.

In this way, it is possible to extend the flight distance without increasing the ejection energy, and it is not necessary to give the bullet excessive energy. Therefore, it is extremely excellent in terms of danger prevention and safety measures. Further, the structure is simple, no precise adjustment is required, and it can be easily added to conventional products, which is of great value in practical use.
