Description

FOLDING STOCK STRUCTURE FOR FIREARMS

Technical Field

The invention relates to the folding stock structure, which can be used in firearms, in which the folding direction can be changed manually without using any tools.

In particular, the invention relates to a folding stock structure for firearms that can be easily folded to the right or left without the use of any additional tools in order to provide ease of carrying and ergonomics in weapons used for sniper or tactical purposes.

Background of the Invention

Firearms such as pistols, rifles and bombs are known as structures commonly used in hunting and defense industries. It is of great importance that the stock portion of the gun can be folded in such structures as firearms, such as rifles fired on the shoulder.

A lot of auxiliary equipment and accessories are used to make the shots fired by users instant or predetermined target more stable and more accurate.

Some of the firearms used today are used with fixed chassis or fixed stock and some of them can be folded on the main body of the rifle by using various folding mechanisms.

It provides ease of handling and ergonomics, especially in weapons used for sniper or tactical purposes. Because different people use these rifles, users have variable requests. The direction of the folding stock may also be desirable to different parties according to the user's preferred direction.

Although there are already systems to meet these demands, the stock folding direction can be changed after assembly / disassembly process, tools are used and the work is slowed down. This leads to problems such as the loss of dismantled parts, the necessity of transporting spare parts and the necessary tools, and makes it impossible to change direction and fold to the desired side when time is limited.

In the literature, TR 2011 01744 numbered utility model application related to the subject “There is a cartridge on the pistol grip. The right-hand and left-handed cartridge slots on both sides of the pistol grip anchor form the side cartridges. The cartridge slots located on the upper side of the pistol grip anchor form the upper cartridges. The pistol grip is designed as a spring. Therefore, the cartridge part of the pistol grip anchor - when the tab is open and parallel to the ground - corresponds to a level lower than the shoulder and pistol grip. As a result, neither the cartridges nor the side and top cartridges come into contact with the rifle barrel when the stock is closed. As a result, when the stock is open, the user can take aim and use the rifle in a healthy way, despite the cartridges installed in the cartridges. ” Said application discloses a rifle assembly comprising a folding stock configuration.

In the literature TR 2004 00602 numbered utility model application relates to “The present invention relates to "Folding stock with carrying function for rifles". Spring locking in both positions, which allows the rifle to be carried by hand in the folded position, the handle section is covered with elastic material, has an eccentric shoulder sleeve, movable around the central pin backwards (from the shoulder to the aiming position) and forward (hand to shoot and carrying position) button with folding stock.”

In said embodiment, a folding stock structure having a portable structure is provided.

Again in the literature TR 2015 08545 useful model application related to the subject “Automatic, semi-automatic and air rifle stock, feature; the engagement adjustment holes and the pivot axis hole formed on said main collector body, the auxiliary body accommodating the engagement adjustment and lock, the butt hinge and the stock retaining hinge connected to said engagement adjustment and the lock accommodating auxiliary body the locking system that prevents the opening movement caused by the shot. ” In the said application, a folding stock structure which can be adjusted for aiming is provided.

Again, in our patent application TR 2019 12957 in the literature, regarding the subject, "The invention relates to a folding stock assembly for firearms that can be easily folded to the right or left without the use of any additional tools in order to provide ease of carrying and ergonomics in weapons used for sniper or tactical purposes." statements are included. Due to the disadvantages mentioned above, it was necessary to introduce a new folding stock structure for firearms.

Disclosure of the Invention From this position of the art, it is an object of the invention to provide a new folding stock structure for firearms which eliminates the present disadvantages.

Another object of the invention is to provide a structure which provides ease of transportation and ergonomics in sniper or tactical weapons.

Another object of the invention is to provide a structure which can be folded on both sides.

Another object of the invention is to provide double-sided folding process in firearms with the help of a long time to eliminate the problem is to reveal a structure.

Another object of the invention is to provide a structure which allows the users to make stock folding in a much shorter time. Description of the Figures

A folding stock structure (A) according to invention consists main parts of, body (1) formed in the middle part of the firearm, stock (2) in connection with said body (1) and the hinge (3) formed between said stock (2) and the body (1) which is enabling said butt (2) to be folded, the locking shaft (4), which is fully seated in the slot on the said hinge (3) when it is locked, allows the stock (2) to be folded by bending it in the direction desired by the user after leaving the housing by applying force against the connections of the said stock (2), the hinge (3) and the body (1), hinge shoe (5), which is capable of moving on the rail it is in, in order to provide the left and right movement of the hinge (3) with the release of the said locking shaft (4) in its slot, fixing pin (6) and shoe spring (7) which pulls the stock (2) and the hinge (3) continuously towards the body (1) and which prevents the structure from changing position without applying any force by ensuring that the slots on the hinge (3) are fully seated on the locking shafts (4) when the parts in the said folding stock structure (A) are brought to the desired position.

While the said stock (2) and the body (1) are assembled to each other, the locking shafts (4) are fully seated in the slots on the hinge (3). The stock (2) and the hinge (3) are continuously pulled to the body (1) by means of the mentioned shoe springs (7) and the fixing pins (6).

Thus, locking shafts (4) are prevented from coming back out of the slots, and the stock (2) and body (1) are prevented from turning to the right or left.

When the said stock (2) is desired to be folded to the right or left, first of all, it is necessary to apply a counter force that will overcome the pulling force provided by the shoe springs (7).

After the said stock (2), hinge (3) and body (1) connections are separated by applying counterforce, the user bends the system in the desired direction and allows the stock

(2) to be folded. There are 3 slots with 90° angles between them on both sides of the mentioned hinge

(3). Thus, the hinge (3), the body (1) and the stock (2) can be positioned independently of each other at 0°, +90° and -90°.

When the parts in the mentioned folding stock structure (A) are brought to the desired position, the slots on the hinge (3) are fully seated on the locking shafts (4) by means of the fixing pins (6) and the shoe springs (7), thus preventing the structure from changing position without applying any force.

When the said folding stock structure (A) is wanted to be brought back to the 0° position, a rapid change in position can be performed by bending it in the appropriate direction without applying pulling force.
