Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a shotgun type model gun capable of simultaneously firing two or more bullets.

(Prior Art) A model gun that uses low-pressure compressed gas or compressed air can have power close to that of a real gun, and in order to eliminate the danger, the upper limit of the bullet firing speed is set by the voluntary regulation of the industry. There is. In the case of a shotgun that fires two or more bullets at the same time, it can be divided into a type that fires multiple bullets from one barrel and a type that bundles multiple barrels that fires one bullet from one barrel. .

However, when firing multiple bullets from a single barrel, setting the firing speed in the case of multiple bullets to the upper limit will greatly exceed the regulation speed in single-shot firing, and conversely within the default value in single-shot firing. When set to, the result is no distance when firing multiple bullets. In contrast,
If multiple barrels are provided, there is no problem as long as the normal conditions of use are adhered to, but only one muzzle remains and the other remains 1
The pressure is concentrated on one muzzle, which greatly exceeds the regulation speed.

(Problems to be solved by the invention) Therefore, in the present invention, in the shotgun type model gun, even if the other muzzle except one is closed, the pressure is not concentrated on the remaining muzzle, and a plurality of simultaneous shots are performed. However, it provides a model gun that can be fired at about the same speed even with a single shot.

(Means for Solving the Problems) The above-mentioned problems are attached to the gun body 1 and each one bullet b
Has a plurality of barrels 3 each having one barrel 2 for firing, and a plurality of chambers 4 following each barrel 2 and stopping the bullet b having a circular cross section at the front of each chamber And a sealing member 5 that is pushed out when pressure is applied from the rear and allows the bullet to pass therethrough.
And a storage case which comprises a supply system for the compressed gas, the same number as that of the barrel 3 and the medicine chambers 4, which accumulates pressure until the time of firing in order to apply the gas pressure to the respective medicine chambers 4 from the rear. A chamber 7 and a valve 8 for sealing the pressure in the pressure accumulating chamber are provided in the front part, and a plurality of operating rods 9 that are movable back and forth and whose rear part operably protrudes from the outside of the accumulating chamber and each operating rod protruding outside the accumulating chamber. Shotgun model including a firing mechanism 11 which acts on the rear part and includes a trigger 10 for simultaneously opening a plurality of valves 8 by a trigger operation, and a gas pressure source 12 for supplying compressed gas to each of the accumulator chambers 7. Solved by cancer.

(Action) The gun body 1 has one gun cavity 2 for firing one bullet each.
A plurality of barrels 3 for waiting for are provided. Each barrel 3 is provided with a cartridge case 6 and a pressure accumulating chamber 7 separately, and since the accumulating chamber 7 has a valve 8, it is guided from a gas pressure source 12. The compressed gas is in a state of being filled in each pressure accumulating chamber 7. Trigger here 10
When is pulled, the valve 8 is opened by the operating rod 9, and the bullet b in front of each accumulator chamber is fired from each barrel 3 at a predetermined pressure.

In such a model gun, even if one barrel 3 is left and other barrels are closed, the valves 8 of the pressure accumulating chambers 7 are simultaneously opened, and compressed gas is discharged to the front of each. Since each system is independent, the pressure of the blocked barrel does not flow to other systems, and the speed of the bullet fired from the remaining barrel 2 does not change.

(Example) Hereinafter, description will be given with reference to the drawings.

FIGS. 1 and 2 show a four-fold center-folding type having four barrels on the left, right, top, and bottom. The gun body 1 has a firing mechanism 11 at the front of a barrel 13 and a lower portion of the front of the mechanism 11. Four barrels 3, 3 are provided vertically and horizontally supported by a shaft 14. The barrel 3,
3 is held in the firing state shown in FIG. 1 by a locking mechanism (not shown).

Each barrel 3 has a loading chamber 15 at the base of the barrel 2 which penetrates the barrel 3 for loading four upper, lower, left and right cartridge cases 6, 6. Each shell 6 has a bullet b inside which has a circular cross section when viewed at least from the front.
Has a drug chamber 4 which is loaded in advance and is coaxially arranged with the gun cavity 2 in a fired state. The bullet b is in contact with the bullet b around the bullet b at a front portion thereof up to a certain pressure. And has an O-ring-shaped seal member 5 which is spread by a bullet b when a pressure higher than a preset value is applied and which allows the bullet b to pass. Reference numeral 16 denotes an inlet for compressed air flow which is opened at the rear end of the medicine chamber 4.

The pressure accumulating chambers 7 are provided on the front part of the gun body 1 behind the cartridge case 6 coaxially with the respective gun cavities 2 and the drug chambers 4 in four vertical and horizontal rows,
A valve opening 17 is provided at the front end thereof, which is continuous with the introduction opening 16 at the rear end of the medicine chamber. A passage 18 is provided for passage. Reference numeral 19 is a seal ring provided around the through-hole 18, and seals the operating rod 9. The operating rod 9 has a valve opening at the front end.
It has a valve 8 for opening and closing 17, and a spring forward in the pressure accumulating chamber 7.
Since it is biased by 20, the compressed gas 9 is accumulated until it is operated by the firing mechanism 11.

The compressed gas G is supplied from the gas pressure source 12 to the respective ports of the four pressure chambers 4 and 4 in the upper, lower, left and right directions through a pressure resistant air supply pipe 12 '. The pressure source 12 is shown as a pressure tank provided in the gun barrel 13. A gas cartridge or the like is connected to the tank by an injection port 12 ″ to supply compressed gas, but the cartridge is still connected. Various non-combustible gases and air are used as the compressed gas G.

The firing mechanism 11 operates the trigger 10 to operate the four valves 8, 8
It is provided to open simultaneously, and the illustrated one is a hammer 21 that is commonly inserted in the four operating rods 9 and 9 projecting rearward of the accumulator chamber so as to be able to move back and forth, and the hammer 21 is pressed backward. Then, a valve opening spring 22 for retracting the operating rods 9, 9 to open the valves 8, 8 and a stopper 23 for locking the hammer 21 for keeping the spring 22 in a compressed state by the hammer 21 in the forward position. When,
And a trigger 10 for releasing the locking of the stopper 23. 24 is a hammer receiver at the rear end of the operating rod, 25 is a stopper 23

Therefore, the cartridge case 6 filled with the bullet b is loaded into the loading chamber 15, the barrels 3 and 3 are returned to the original state, and the firing state is set.
Since the compressed gas G of each of them fills the inside of the pressure accumulating chamber 7, when the firing mechanism 11 opens the four valves 8 ... Simultaneously by the operation of the trigger 10, the bullets b, b are fired simultaneously from all the bores 2 ... .

The model guns shown in FIGS. 3 to 5 are of a type that uses a magazine 30 preloaded with a plurality of four-type cartridge casings 6,
By moving the firing mechanism 11 back and forth by operating the lever 31, the pod and the next cartridge case 6 are loaded. That is, a slide member 33 having a pressure accumulating chamber 7 is provided in the gun body 1 so as to be retractable so that the cartridge case 6 can be pushed into the rear of the loading chamber 15 from the magazine 30, and the four cartridge cases 6 are loaded when they are pushed up. Room
The slide member 33 is configured to be moved forward by a lever operation in order to push it into 15. Therefore, the firing mechanism 11 is partially provided on the slide member 33, and the trigger operation transmission member 34 that connects the trigger 10 and the stopper 23 is provided on the gun body 1 so as not to interfere with the forward and backward movement of the slide member 33. ing.
Reference numeral 35 denotes an extractor pivotally supported on the front portion of the slide member 33, which is locked to the rear locking portion 36 of the quadruple-type cartridge case 6 and holds the cartridge case 6 so as not to shift from the slide member 33. Reference numeral 37 denotes a cartridge case pushing spring in the magazine 30. The other structure is the first
Since it may be similar to that of the embodiment shown in the figure, the reference numerals are used and detailed description is omitted.

In the case of this example as well, the operation is exactly the same as the above-mentioned example except the operation of mounting and dismounting the quadruple-type cartridge case 6, and by operating the lever 31,
When the trigger 10 is pulled in a state in which is set, the stopper 23 is disengaged via the transmission member 34, and the hammer 21 presses the two hammer receivers 24 to open both valves 8 and 8. Therefore, the step circles b and b are fired at the same time. In the above example, the case where the number of barrels is 4 has been described, but it is easy to set the number to 2 or 3 or increase to 5 or more.

(Effect) Since the present invention is configured and operates as described above, it is possible to fire two or more bullets at the same time, and a system for supplying compressed gas to the bullets in the cartridge case to fire each bullet Since the individual accumulators 7 are independent of each other and are not affected by other factors, even if the muzzle is blocked leaving only one place, the pressure will not concentrate on the remaining muzzle, and multiple shots will occur. It is very safe because the bullets are fired at the same speed as at the same time, and it has the effect of enabling commercialization of shotguns.
