Abstract

(57) [Summary] [Purpose] When a ball bullet jumps out of a chamber, it imparts an upward rotational force to the ball bullet, delays the parabola drawing the ball bullet for a certain period of time, and the rotational force of the ball bullet drops. By the way, a parabola is drawn and dropped to increase the flight distance of a ball. A tongue is projected on an upper surface of an opening at a ball projecting opening of the chamber, the tongue deforms a part of the O-ring toward the center of the opening, and the ball passes through the O-ring. At this time, the ball bullet is rotated toward the sky.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toy gun that emits a bullet (plastic bullet) using the pressure of compressed air or gas, and a high-speed rotating force is applied to the bullet to increase the flight distance. Regarding

[0002]

[Prior Art]

 A conventional toy gun utilizing the pressure of compressed air or gas will be described with reference to FIG. 1 is a case, 2 is an inner barrel held in the barrel portion 1a of the case 1, 3 is a barrel base connected to the inner barrel 2, 4 is a chamber housed in the barrel base 3, and 5 is a chamber. A spring 7 interposed between the tip of the chamber 4 and the barrel base 3 to absorb a reaction generated when the ball 6 of the chamber 4 is fired is housed in the valve portion 3a at the rear end of the barrel base 3. It is a valve and is constantly pressed toward the valve seat by the spring 7a.

Reference numeral 8 is a hose connector connected to the barrel base 3 to which a hose for compressed air or gas is connected. 9 is a trigger, 10 is a trigger bar that moves in a horizontal direction by pulling the trigger 9, 11 is connected to the trigger bar 10, and when the trigger bar 10 moves, the valve 7 is a spring of a spring 7a. Compressed air and gas from the hose connector pushed up against the force are introduced into the valve portion 3a, the gas passage hole 3b of the barrel base 3, and the chamber 4.

Reference numeral 12 denotes a magazine which is detachably set to the case 1, and accommodates a large number of ball bullets 6 pressed upward by the spring 12a. The ball 6 is adapted to enter the chamber 4 through the ball passage hole 4a formed in the chamber 4. Reference numeral 13 is a safety for preventing erroneous operation of the trigger 9, and 14 is a magazine catch for ensuring mounting of the magazine 12 in the case 1.

Next, the operation will be described based on the above-mentioned configuration. Since the ball 6 from the magazine 12 is pushed up by the spring 12a, the ball 6 is moving into the chamber 4. In this state, when the trigger 9 is pulled, the valve 7 is pushed up and compressed air or gas is supplied from the gas hole 4b of the chamber 4 and hits the rear surface of the ball bullet 6 to move it forward.

However, since the O-ring 4c having an inner diameter smaller than the outer diameter of the ball bullet 6 exists in the chamber 4, the ball bullet 6 temporarily stops moving at this O-ring 4c. When the pressure on the rear surface of the ball 6 rises in this state, the ball 6 overcomes the elastic force of the O-ring 4c and vigorously jumps out of the chamber 4 and is launched to the outside through the inner barrel.

[0007]

[Problems to be solved by the device]

 By the way, when the ball 6 is ejected from the chamber 4 due to the pressure of compressed air or gas, the ball 6 comes into contact with the O-ring 4c over the entire circumference and is ejected. Therefore, there is a problem that the ball 6 falls in a parabola due to gravity and falls, resulting in a short flight distance.

The present invention is intended to solve the above-mentioned problems, and an object thereof is to give an upward rotational force to a ball bullet when the ball bullet jumps out of the chamber so that the ball bullet creates a parabola. To delay the drawing for a certain period of time, draw a parabola when the rotational force of the ball has fallen and drop it, so as to provide a ball firing device for a toy gun with a long flight distance is there.

[0009]

[Means for Solving the Problems]

 The ball-firing device for a toy gun of the present invention is intended to achieve the above-mentioned object, and the means is that the ball-foam in the chamber is compressed by the compressed air or gas pressure from the back side to move the ball-foam to the O-ring. In a ball-firing device for a toy gun, which is adapted to be fired against elastic force, a tongue piece is projected on the upper surface of the opening at the ball-ejecting opening of the chamber, and a part of the O-ring is projected by the tongue piece. Is deformed toward the center of the opening so that when the ball passes through the O-ring, the ball is rotated toward the sky.

[0010]

[Action]

 In the ball-firing device for a toy gun of the present invention constructed as described above, the tongue is projected on the upper surface of the opening at the ball projecting opening of the chamber, and by this tongue, a part of the O-ring is moved to the center of the opening. When the ball bullet passes through the O-ring, the ball bullet is rotated toward the sky when passing through the O-ring. The ball travels longer because the ball drops in a parabola when the rotational force drops.

[0011]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. The one shown in the drawing shows the portion of the chamber 4, but the other portions are the same as those shown in FIG.

In the chamber 4 according to the present invention, the tongue piece 4e is formed on the upper surface of the opening 4d from which the ball bullet 6 is projected, that is, on the side opposite to the surface on which the ball passage hole 4a is formed. The O-ring 4c in the conventional example is housed in the chamber 4, but the O-ring 4f in the present invention is characterized by being arranged along the end face of the opening 4d. Therefore, when the O-ring 4f is arranged along the end surface of the opening 4d, the portion of the O-ring 4f that contacts the tongue 4e is curved inward due to the presence of the tongue 4e.

When the chamber 4 thus constructed is housed in the barrel base 3, the O-ring 4f is sandwiched between the end surface of the opening 4d of the chamber 4 and the catch 5a of the spring 5 in FIG. It is fixed in the closed state. Therefore, the ball 6 that has entered the chamber 4 from the ball passage hole 4a is ejected by the back pressure of the gas by pulling the trigger 9, but when the ball 6 passes through the O-ring 4f, the tongue piece Since the friction with the inwardly curved portion is increased by 4e, the ball 6 rotates right as shown by the arrow in FIG.

That is, since the ball 6 projecting from the inner barrel 2 is given a rotation in the sky direction, the time for drawing the parabola of the ball 6 is delayed, and therefore the parabola is about to fall when the rotational force of the ball 6 is reduced. Since the ball 6 draws and falls, the flight distance of the ball 6 becomes long.

[0015]

[Effect of the device]

 As described above, the present invention bends the O-ring inward so as to rotate the ball toward the sky when the ball passes through the O-ring. When the parabola is drawn with a delay and the rotational force of the ball is reduced, the parabola is drawn and the ball falls. Therefore, the flight distance of the ball is increased.
