RU40455U1 - REPLACEABLE TURNING REAR UNIT UNDER CARTRIDGE - Google Patents

Abstract

The 4-charge swivel interchangeable barrel unit is a one-piece design that rotates in any direction around a special axis provided on the gun frame. The block is fixed on the axis by a latch against spontaneous removal. After firing 2 shots, the block can be rotated in any direction, to replace with 2 other barrels. Two electrical contacts for firing a shot are in the front of the axis, on the frame of the gun and move forward when you press the trigger. The block is fixed from spontaneous circular rotation by a latch in the rear of the gun. Having retained the “flat” look, the new gun has the ability to 4 shots without changing the block. Since the block has a flat rectangular shape, it is very convenient to store and remove it from the pouch. Using an additional unit allows you to have the opportunity to 8-shots with increased speed and ease of reloading.

The essence of the utility model.

The utility model relates to weapons and is a removable rotary barrel unit for a cartridge for gas and rubber cartridges for self-defense pistols.

The essence is as follows:

Since the adoption of the 18x45 ammunition in Russia, two types of barrelless self-defense weapons have been certified. This is a 4-shot PB-4 "OCA" pistol manufactured by the Sergiev Posad Research Institute of Industrial Defense, an MR-461 "Strazhnik" pistol manufactured by the Izhevsk Mechanical Plant. Both of these models have certain disadvantages associated with operation in real conditions.

The “Osa” 4-charge pistol has a rather large-sized case, which impairs the comfort of covert wearing. In addition, the reload system provides for the alternate replacement of used ammunition with new ones, which is not so simple in real conditions and takes a lot of time. The storage of additional ammunition separately is also difficult, and the 2-shot “Strazhnik” pistol has a flatter case and compact dimensions. However, two shots are clearly not enough in real stressful situations.

The designers provided, it would seem, this drawback, using an additional removable 2-charging unit. However, changing the blocks, due to their design features, is not so simple, especially in a combat situation. It is even more difficult to remove the spare unit from the clothes, because it is simply impossible to store this unit in the pouch due to the shape of the case. Both models have one more drawback: a short appearance, not even remotely resembling a serious weapon of self-defense. This is due to the legal feature of the barrelless type of weapon. This model eliminates all of the above drawbacks and opens up new possibilities for self-defense weapons. The 4-charge swivel interchangeable barrel unit is an integral design that rotates in any direction around a special axis provided on the pistol frame. The block is fixed on the axis by a latch against spontaneous removal. After firing 2 shots, the block can be rotated in any direction, to replace with 2 other barrels. Two electrical contacts for firing a shot are in the front of the axis, on the frame of the gun and move forward when you press the trigger. The block is fixed from spontaneous circular rotation by a latch in the rear of the gun. Having retained a “flat” look like that of the “Guard”, the new gun has the ability to 4 shots without changing the block. Since the block has a flat rectangular 4) shape, it is very convenient to store and remove it from the pouch. Using an additional unit allows you to have the opportunity to 8-shots with increased speed and ease of reloading.

It is not unimportant that the gun acquired features similar to real weapons, and with a carefully designed design it can have a very formidable appearance, which corresponds to the serious capabilities of the ammunition. The drawing No. 1 shows a General view with a rotary receiver unit. Position 1 is a rotary receiver unit. The drawing No. 2 shows a side view without a rotary barrel unit. In drawing No. 3 shows four charging removable rotary receiver unit for munition 18 × 45T.

The rotary barrel unit is made for four cartridges located capsule to each other. When firing two rounds of ammunition, we change the block without reloading for firing two other rounds. The list of figures of drawings and other materials. Drawing number 1. A general view with a swivel receiver unit is shown. Drawing number 2. Side view without a rotary barrel unit Drawing No. 3. Four charging detachable rotary receiver for ammunition 18 × 45T.
