BACKGROUND OF THE INVENTION

The present invention relates to a hammer and a new hammer spring that accelerates the firing time in weapons fired by striking a pin.

The invention particularly relates to a hammer spring that does not require any bending or twisting operation.

By definition, a weapon is a mechanical or electronic device comprising multiple parts that can harm, injure or neutralise, sicken, disintegrate or destroy living beings and specified targets from a certain distance.

Firearms include weapons of all types and sizes, from shotguns to pistols. Firing occurs when the cocked hammer is activated, and the pin hits the bottom plate. The movement of the hammer striking the pin is caused by the movement generated by the pulling of the trigger being transmitted to the hammer. Firing occurs as a result of the hammer striking the pin or capsule.

The most common for the installation of the hammer are helical-coil springs. Here the spring must be twisted into a spiral. These springs have a long service life, but they work slowly. In addition, they are difficult to obtain as a manufacturing method. In the state of the art, these springs can be seen in applications numbered TR1998/01446, TR2011/04292, TR2011/05715, TR2012/10764, TR2013/04544.

V-type hammer springs are used to eliminate the above drawbacks. V-type hammer springs are fast in transferring the movement to the hammer after installation, but since they contain a V-shaped bending-twisting-forming during installation, they often break, they are not long-lasting.

SUMMARY OF THE INVENTION

Based on the prior art, the need to design a spring that is long-lasting and quick in transferring movement to the hammer after installation has emerged. In order to realise this object, a hammer spring with a thickness (k), a width (e), a length (b), structured as b>e>k to ensure flexibility, shaped without any bending/twisting forming was obtained. Thus, a fast responding and long-lasting hammer spring is obtained.

In another embodiment of the invention, the width dimension (e), which is shaped in such a way that its dimension (e′) decreases as it goes from the part where the gun is connected with the body to the part in contact with the hammer (e>e′), has been obtained. In this way, the flexing capability of the hammer spring can be further increased.

In another embodiment of the invention, a thickness dimension (k) is obtained which is formed (k>k′) in such a way that it decreases (k′) from the part where it is connected to the receiver (10) of the weapon to the part in contact with the hammer. In this way, the flexing capability of the hammer spring can be further increased.

In another embodiment of the invention, a pin locating cavity is configured in the part where the hammer spring meets the body. In this way, the hammer spring can be easily installed and removed on the body.

The hammer spring that is the subject of the invention will be better understood when explained by referring to the figures and reference numbers below.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a perspective view with the hammers (20) are cocked. The firearms have a main receiver (10), which contains the parts necessary for firing and which operate in an interconnected manner. In firearms, the hammer (20) is the part that strikes the firing pin (40) to cause the firing pin (40) to fire the ammunition (not shown). The sear (30) is the part that holds the hammer (20) in tension when the weapon is hammered, releases the hammer (20) when the trigger is pulled and allows the hammer (20) to strike the firing pin (40) using the impulse of the hammer spring (50). In firearms, the firing pin (40) is the part that strikes the ammunition with the impact of the hammer (20) and enables the ammunition to be fired. The hammer spring (50) is the spring that becomes taut when the weapon is hammered, is integrated with the hammer, and ensures that the hammer strikes the firing pin with high thrust when the trigger is pulled, and the sear releases the hammer.

There are various weapons known in the prior art and their specific hammering methods. Our invention is primarily configured for use in crushing weapons. The barrel of the weapon is opened (breaking action takes place) by means of the opening latch/lever/button (depending on the structure of the weapon) on the receiver (10), and after the required amount of opening, the hammer (20) in the receiver (10) is moved backwards towards the point where it will be cocked by means of the cocking mechanism and the sear (30) catches the hammer. As the hammer (20) moves to cocked position, the hammer spring (50) in contact with the hammer (20) becomes taut. When the trigger is pulled and the shot is fired, the sear (30) releases the hammer (20) and the hammer spring (50), which has become taut, pushes the hammer (20) with a high thrust force, causing the hammer to strike the firing pin (40); thus, the shot is fired.

FIG. 2 is a drawing showing the perspective shape of the hammer spring (50) of the invention. The hammer spring (50) has a thickness (k), a width (e), a length (b). In order to ensure flexibility, it is shaped as b>e>k and has the ability to stretch without any bending/twisting on it. The thickness (k), width (e) and length (b) can be configured in different dimensions according to the expected thrust and speed of the spring. The hammer spring (50) is shaped in such a way that its width (e) decreases (e′) as it moves from the part (52) where it is connected to the receiver (10) of the weapon to the part (53) in contact with the hammer (20). (e>e′). FIG. 3 is a two-dimensional figure showing a cross-section of the inventive hammer spring (50) from the thickness (k) part in length. Similarly, the thickness (k) of the hammer spring (50) is shaped in such a way that the thickness (k) decreases as it moves from the part (52) where it is connected to the receiver (10) of the weapon to the part (53) in contact with the hammer (20). In addition, in the part (52) where the hammer spring (50) meets the receiver (10), a pin locating cavity (51) is provided for easy assembly and to prevent the spring (50) from changing its position.

Between FIG. 4 and FIG. 7, some of the positions of the hammering spring (50) in use in the weapon are illustrated for the understanding of the subject.
