Abstract

A bullet used for an air gun, a gas gun, etc. has a rear conical shape centering on this head, because the movement to the firing position is centered on the inner diameter of the bullet or the bottom of the bullet, and the bullet head is the fulcrum. The bottom swings. In particular, this swinging is prevented because an inclination occurs due to variations in elastic deformation and plastic deformation depending on the product processing accuracy, and the center axis shifts and leads to wobbling during flight.

Description

The present invention relates to a shape for stabilizing a posture of a bullet used for an air gun and a gas gun when being loaded, and for stabilizing a bullet posture at the time of firing.

In target shooting and hunting shooting, commercially available bullets are generally used, but since it is not easy to check the accuracy of the bullets, they are used in that state. Therefore, bullets are included as an element that causes the landing point to deviate from the target.

The bullet flying toward the target moves to a firing position by pushing a bullet or a bullet manually. A bullet is composed of a bullet head guided by a barrel small diameter portion, a multi-striped spiral groove formed in the barrel, and a skirt bottom portion that receives thrust (air pressure, etc.) by elastic deformation or plastic deformation of the small diameter portion. . When the movement method to the firing position is a rod-shaped object, the bullet inner diameter part is manual, and in the case of manual operation, the rear cone bottom part is the force point and the bullet head is the fulcrum, so the rear cone bottom part swings around this head part To do. In particular, this oscillation causes an inclination due to variations in elastic deformation and plastic deformation depending on the product processing accuracy, and the central axis is deviated and becomes an element that leads to fluctuation during flight.

The means taken to achieve this purpose is a bullet used in an air gun or the like, and when the bullet is moved to the firing position, the bullet head provided on the bullet skirt with the bullet head outer diameter as a fulcrum Two-point support with the same diameter as the outer diameter supports the gun barrel so that it can be loaded at the firing position almost accurately with respect to the barrel, and is subject to elastic deformation and plastic deformation due to the propulsive force (air pressure, gas pressure) at the time of launch. Set the bullet posture at the time of shooting to a stable posture.

And, the above-mentioned bullets are elastically deformed or plastically deformable annularly at the bottom of the skirt that closes the spiral grooves formed in the barrel with the propulsive force (air pressure, gas pressure, etc.) received at the time of firing, and the collar is the skirt. The warhead, the second constricted portion, the inner diameter portion, and the respective portions are concentric to prevent pressure loss and stabilize the posture when moving away from the barrel while flying away from the barrel.

Next, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show the first embodiment, and FIG. 3 shows the second embodiment. In FIG. 1, reference numeral A denotes a bullet body.
The bullet A of the first embodiment has a hollow drum shape with a constricted halfway, and a second constricted portion 3 having the same diameter as the outer diameter X of the bullet head 2 is formed in the bullet skirt portion 1. An annular collar 4 having a diameter Y slightly larger than the spiral groove b1 formed in the barrel B is exhibited.
Further, it has a bullet inner bottom edge 5, which is substantially concentric with 4.

The bullet A formed in this way pushes and moves the bullet inner diameter portion 8 in the case of the rod-like object 7 until it is loaded into the barrel (fired position). When loading into a barrel, 8 is a force point, X diameter is a fulcrum, and 3 is an action point, and is loaded at the firing position. In the case of manual operation, 6 is a power point, X-diameter is a fulcrum, and 3 is an action point, and the firing position is loaded. By this series of flows, the barrel is supported at two points at the X diameter and 3 and moves to the firing position parallel to the barrel inner diameter.

Next, the second embodiment will be described with reference to FIG. 3. When the barrel is loaded, the X diameter of the bullet A first moves elastically or plastically with respect to the barrel inner diameter portion and the spiral groove b1, and then moves. 4 is loaded in the same manner. At that time, the concentricity between 4 and 5 is maintained, in other words, the loading posture due to the difference in thickness is prevented from shifting.

Effect of device

Since the present invention is configured as described above, the following effective effects are exhibited.
According to the first aspect, since the bullet is accurately loaded into the barrel, the original accuracy of the barrel can be exhibited, the target point can be easily corrected, and the propulsive force is efficiently transmitted to the bullet body. Where bullets are subject to elastic or plastic deformation due to propulsive force (air pressure, etc.) at the time of firing, the frictional resistance of the bullets is averaged, and when the propulsion force (air pressure, etc.) and bullet weight are constant, the flight distance is Almost uniform. According to the third aspect, since the outer diameter surface and inner diameter surface of the bullet are substantially concentric, the axial center is maintained, and after the launch, the rotational movement of the bullet by the spiral groove of the barrel is stabilized, so the posture during flight is stable. To do.
