Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rotary magazine for a toy gun.

[0002]

2. Description of the Related Art Rotary magazines for toy guns that can fire bullets currently on the market can be broadly classified into two types. One is a type using a cartridge, and the other is a so-called caseless type that does not use a cartridge. As shown in FIG. 14, as a toy gun equipped with a caseless type rotating magazine, a large number of bullets b are loaded inside a shroud i formed below a barrel a, and the bullet b is loaded by a spring c. It is conventionally known that a plurality of circular rubber chambers e are arranged along the circumferential direction on the front surface of a cylinder d which is pressed rearward and faces the rear of a barrel a and a shroud i.

[0003] The bullet b in the shroud i has a spring c
And formed on the crane f and the frame g
After passing through the V-shaped passage h, it is sequentially pushed into one of the rubber chambers e provided on the front surface of the cylinder d. rubber·
The bullet b pushed into the chamber e is sent to the cylinder d which rotates by a fixed angle each time the trigger is triggered, and finally reaches the barrel a, that is, the firing position, and is pulled behind by the trigger. It is fired by the power of the compressed gas injected from the gun and jumps out of the muzzle.

[0004] The above-mentioned conventional toy gun is preferred by users because it can fire a larger number of bullets continuously than an actual gun. However, from the user's desire to reproduce the actual gun more faithfully, since this is loaded with bullets in different parts from the actual gun, not only the internal mechanism but also the appearance Had a problem that it would be significantly different.

Further, a plurality of chambers which are long in the axial direction are arranged along the circumferential direction inside the cylinder, and a gas inlet which communicates with a gas outlet on the gun side is provided at the rear end of each chamber. At the rear of the chamber, a spring that pushes the bullet forward is incorporated. Between the first and second bullets at the forefront of the chamber, a pin that protrudes into the chamber and a pin that moves toward the chamber at the firing position are inserted. Rotary magazine for toy guns with cams to protrude
No. 12399. This satisfies the user's desire that the appearance is close to that of an actual gun and that multiple bullets can be fired continuously, since more bullets than the actual gun are loaded in the cylinder like the actual gun. It has become something. However, this type cannot be used for a toy gun of a type in which a gas chamber is built in a cylinder since a medicine chamber is formed almost entirely except for a central portion inside the cylinder.

[0006]

SUMMARY OF THE INVENTION The present invention is similar in appearance and mechanism to a real gun, can fire a larger number of bullets continuously than a real gun, and furthermore, has a gas chamber provided inside the cylinder. It is an object of the present invention to provide a rotary magazine for a toy gun that can be used for both types and to be installed inside a grip.

[0007]

According to the present invention, there is provided a rotary magazine for a toy gun which excludes a cylinder, a gas ejection path extending in the axial direction inside the cylinder, and a gas ejection path behind a front end face of the cylinder. The part includes a bullet storage chamber formed along the circumferential direction, and a magazine cover covering a front surface of the bullet storage chamber. In the cylinder, a plurality of bullet passage holes are provided on the front end face at equal intervals in the circumferential direction, and the magazine cover has
A defective portion is formed to allow communication between the one end of the bullet storage chamber and the bullet passage hole, and one end of the bullet storage chamber behind the defective portion has a bullet receiving section along a circumferential direction inclined toward the other rear end. The bullet receiving section is formed so that a partition wall near the other end of the bullet receiving section is provided so as to be movable in the circumferential direction, and the partition wall near the other end is urged toward the one end.

When the bullet is continuously pushed into one end of the bullet storage chamber through the bullet passage hole of the cylinder and the missing portion of the magazine cover, the inserted bullet pushes the partition wall near the other end toward the other end against the urging force. The plurality of inserted bullets are circumferentially loaded into the bullet receiving section of the bullet storage chamber. When the empty bullet passage hole after the bullet launch reaches the front of the defect, the bullet located near one end of the bullet storage chamber,
It is pushed forward by the biasing force applied to the partition wall near the other end and the shape of the bullet receiving section, and is automatically engaged with the bullet passage hole through the defect. When the bullet engaged with the bullet passage hole reaches the front of the gas ejection path, it can be fired by the pressure of the gas ejected from the gas ejection path.

[0009] The surface of the partition wall near the other end on the bullet receiving section side may be inclined toward one rear end. In this case, the bullet reaching the one end of the bullet storage chamber can be reliably pushed forward by the pressing force of the partition wall near the other end. While storing the gas chamber inside the cylinder,
It is also possible to form a bullet storage chamber in front of the gas chamber. Thus, a bullet storage chamber can be easily formed behind the bullet passage hole of the cylinder simply by storing the gas chamber in the cylinder. In addition, a bullet chamber made of an elastic material having a projection formed on the inner surface and a concave portion formed at a position corresponding to the projection on the outer surface is fitted into the bullet passage hole, and the bullet is engaged with this projection. Take it,
When the bullet receives gas pressure, the projections may be easily displaced toward the outer surface due to the presence of the recess to enable the bullet to be fired.
