Abstract

PROBLEM TO BE SOLVED: To load a bullet manually by providing a rotatively opened-and-closed type barrel and enable a visual check if the bullet is loaded in a rifle by folding the barrel double so as to open. SOLUTION: A barrel 14 is connected to a pivot (11) with a hinge so as to be rotated between a closed position in alignment with a receiver unit with the pivot 11 and an open position bent by an angle with respect to the pivot. A cartridge is conveyed from sideward and a cartridge case is removed from a bottom of the pivot 11.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-automatic sports rifle and a shotgun having a smooth and / or spiral hole.

[0002]

2. Description of the Prior Art At present and on the one hand, only conventional rifles with one barrel or two parallel or stacked barrels have a rotary opening and closing mechanism which makes the barrel rotatable on a rotation axis. have. These rifles are rear-loading guns, with the restriction that they must be reloaded by inserting a cartridge into the barrel or by inserting a cartridge into each of the barrels each time, The gun has an advantage in terms of safety against accidental firing, thanks to the fact that the gun can be opened and the presence of ammunition can be checked by looking at the barrel.

On the other hand, semi-automatic sport rifles and shotguns have only one barrel having a coaxial configuration between the barrel axis and the breech hole, and can deliver two or more bullets, One bullet in the barrel and at least one other bullet on the position feed means are fired in succession.

[0004]

However, these semi-automatic sports rifles and shotguns do not have a rotary opening / closing mechanism, and therefore cannot be opened.
There is no security equivalent to that of a conventional rotary rifle, and it cannot be checked whether or not a bullet is loaded in the gun.

[0005] It is therefore an object of the present invention to have a rotating openable barrel, and thus to manually load a bullet therein and to "see" whether or not the rifle is loaded with a bullet. To provide a semi-automatic rifle that can be folded into two and opened.

It is another object of the present invention to create a semi-automatic rifle that can be opened and held open when not in use for maximum security against accidental firing. And is of particular value in the field of trap shooting or similar sports practice.

Another object of the present invention is to create a semi-automatic rifle with a smooth or helical barrel that is as secure as a conventional rotary rifle. Due to loading from below and discharging from below, a semi-automatic rifle with superior quality in two different types of guns: opening and security of rotary guns, precision, target construction and the possibility of using two hands Characteristics are found.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a pivot (11) fixed to the tail and having a trigger and bullet feed means, a barrel having a breech hole (15), a metal strip (16) and a gripping stem. A semi-automatic sports rifle or shotgun comprising (14), wherein the barrel (14) is folded at an angle with respect to the pivot, in a closed position aligned with the breech bolt unit in the pivot. This is achieved by the semi-automatic sports rifle or shotgun, which is hinged (21) to the pivot (11) for rotation of the barrel between the open positions.

The barrel bottom is connected to the pivot by a horizontal pin (21), which pin forms a rotation axis of the barrel between the closed position and the open position, and the pin is Preferably, it can be withdrawn to remove the barrel from the pivot.

Further, the barrel bottom has a rear appendage, which locks the pivot when the barrel is in the closed position, and the locking operation is performed by trigger means at the lower part of the pivot. Preferably, it is controlled.

[0011] Furthermore, a bullet feed means is provided in the lateral direction,
Preferably, the ignited cartridge case is removed from the bottom by the bullet feed means.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A rifle has two main units. One includes a trigger 12 and a floor tail 1
A pivot 11 fixed to 3, the other being a barrel 14 with a metal strip 16 and a stem 17 associated with a breech bolt (or sleeve) 15.

The pivot 11 houses a trigger 12 having a breech unit 18. The unit 18 has a bullet feed means 19 arranged on one side of the gun and means for removing the cartridge case from the bottom thereof. And are combined.

For said bottom, the pivot 11 is provided at the front with a projection 20 having two perforations.
The breech hole or sleeve 15 of the barrel 14 is connected by a horizontal pin 21.

The pin 21 thus forms the axis of rotation of the barrel 14, whereby the barrel is folded at an angle to the pivot 11, in a closed position aligned with the breech bolt unit 18. Between the open positions.

FIGS. 1 and 2 show each of these two closed and open positions.

A mechanism (not shown) includes a rear accessory 1 of the play bottom.
Interacting with 5 ', of which only the control trigger means 22 is shown, which provides a locked or unlocked state of the barrel in its closed position.

Thus, the barrel of the semi-automatic rifle can be rotated and opened by a simple rotation about the pin 21 to achieve the above-mentioned purpose.

In addition, the pin 21 can be withdrawn, separated into the two main units of the gun as shown in FIG. 3, and for the purpose of reducing the failure of the semi-automatic rifle when not in use, It can be divided into two parts in the case and carried in a short case.

[0020]

As is apparent from the above description, according to the rotary semi-automatic rifle according to the present invention, the barrel is folded in two in order to check whether or not the rifle is loaded with a bullet. The opening can be provided, and the effect that the opening state can be maintained can be achieved.
