Description

FIREARM HAVING A LEVER-LATCH TRIGGER MECHANISM
Technical Field
The present invention relates to the firearms in any calibre having a Lever-latch - Trigger mechanism that belongs to the lever-action firearms category particularly designed for repeating shooting, which interrupts sequential shooting after each shot and enables cocking the firearm manually by a user for reshooting.
Prior Art
In firearms designed for sequential shooting, generally, it is necessary to cock the firearm manually through a mechanism (make ready the trigger and hammer for shooting and move the cartridge into the barrel chamber) for repeatedly firing after each shot. Said manual cocking action after each shot is compulsory in hunting regulations of some countries (regions). Moreover, according to many regulations, it is necessary to take the trigger finger off the trigger during the cocking action and to perform cocking action manually as per this condition.
In the state of the art, patent documents numbered DE105618, US1360873, and the patent document numbered CH40069, and titled "Recoil Loader with Sliding Barrel", disclose firearms which prevent the serial shooting and feature a mechanism that provides manual cocking for re-shooting the firearm. In the shotgun type firearms, once the trigger is pulled and the hammer hits the needle; the cartridge is fired and by means of the energy generated in the course of firing (explosion), the bolt of the shotgun moving backwards. In the firearm disclosed in the patent document numbered CH40069, the moving back mechanism is locked by means of being held via a 'pivot yoke' in this position. Pivot yoke provides the function of holding (locking) the moving bolt by compressing. Pivot yoke is connected to another component and can move up and down from the contact point. Thus, the compressing move may occur. A hinge is positioned at the other end of the Said part. For re-firing, the user interferes with the component manually. For this, there is a part ("activator finger") connected to the component and can be reached by the trigger finger. When the user pulls this part, the component moves back and down and pulls the pivot yoke that compresses the moving bolt. Thus, the bolt moves forward through springs and provides cocking for the next shooting. However, in the Said firearm, locking as a result of compression provided by the movement of two interconnected rod-shaped parts creates abrasion in a short time and the risk of failure as a result of this abrasion in the mechanism parts. Additionally, in the Said firearm, when the "activator finger" is held down continuously by the user, the gun can operate in a semi-automatic way since there will be no compression function.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a firearm in any calibre having a Lever-latch mechanism, that belongs to the firearm category, particularly to the category of guns designed for sequential repeatedly shooting, which interrupt the sequential shooting after each shot and enable to cock manually by a user for re shooting, characterized in that;
- The mechanism, which interrupts the sequential shooting and provides manual cocking for reshooting has an optimum number of parts and has a simple and solid structure, thus the risk of failure is minimized; - It is ensured that the trigger is immobilized when the user keeps the lever-latch pushed down, so that semi automatic operation is not possible, and thus, the innovational firearm provides safe shooting under all conditions.
DESCRIPTION OF THE INVENTION
The inventive firearm has a lever-latch - trigger mechanism that works connectedly. Said lever-latch - trigger mechanism interrupts the sequential shooting after each shot and ensures a manual cocking process to be conducted by the user for reshooting.
The said mechanism is specially designed to have a minimal number of parts. The parts are designed to have the optimal sizes. Thus, the use of parts that are hard to manufacture, and that increases the failure risk are avoided in the present invention.
The mechanism consists of a lever-latch and trigger parts. Trigger and Lever-latch function interconnected with each other. The trigger is the part that actuates the shooting sequence of the firearm. The Lever-latch is the part that used to cock the firearm again for reshooting after it has been shot once. After firing, the user removes his index finger from the trigger; presses the lever-latch and ensures that the gun is ready for firing. Trigger becomes non-functional when the user presses the Lever-latch. Thus, a safe cocking process is ensured, and semi automatic use is prevented.
Operating principle of the inventive firearm is as follows:
On the Lever-latch, there is at least one horizontal pin, which is perpendicularly positioned to the direction of the gun. When the gun is fired by pulling the trigger, the bolt of the gun moves backwards (to gun stock) in the direction of the gun in consequence of explosion energy. In the moving bolt of the gun, which is characterized by the invention, there is at least one groove. When the gun bolt moves backwards, the horizontal pin of the Lever-latch clamps to the bolt groove. Thus, the gun bolt remains in its rearward position. The spring, which preserves the position of the Lever-latch, enables the revolving pin to move to the groove. When the gun bolt gets its rearward position, the groove corresponds to the horizontal pin of the Lever-latch. The bolt moves backwards until the groove axis will get the position of the horizontal revolving pin axis and the Lever latch catches the bolt in the rearward position due to the spring.
Then, the user pushes the Lever-latch and ensures that the bolt moves to its initial position by moving forward to the barrel direction. The user ensures that the horizontal pin is released from the bolt groove by pushing the Lever-latch downward. Thus, the bolt is released from the Lever-latch. The bolt released from the lever-latch moves to its initial position and becomes ready to shoot by pushing the cartridge carried from the magazine. When the lever-latch is pressed and released, the bolt is released from the lever-latch pin. The lever-latch returns to its initial position (before being pressed) under the influence of the spring.
As is seen, after shooting for once, the user needs to press the lever-latch to reshoot. However, when the Lever-latch is pressed (when it is remained pressed), the trigger remains inactive. In this case, the user must release the Lever-latch to shoot. Thus, processes of pressing the Lever-latch and pulling the trigger are made as fully separated moves from each other. There is at least one vertical pin on the upper side of the trigger. When the Lever-latch is pressed, the horizontal pin of the Lever latch represses the vertical pin of the trigger. Thus, it is not possible to press the trigger and the trigger does not function. In this way, it is prevented that the user releases the bolt by keeping the Lever-latch pressed (disables the semi-automatic function of the gun). When the user releases the Lever-latch, the Lever-latch goes back to its initial position before pressing under the influence of the spring. In this way, the pressure on the trigger is removed and the trigger can function.
The present invention is described hereinafter in detail by means of illustration with attached drawings (figures), herein;

DETAILED DESCRIPTION OF THE INVENTION
The present invention is a firearm in any calibre having a Lever latch (3) - trigger (4) mechanism that belongs to the lever action gun (1) category, particularly to the category of guns (1) designed for repeating shooting, which interrupts the sequential shooting after each shot and enables to cock the gun (1) manually by a user for reshooting, characterized in that, it comprises;
- a trigger (4) that ensures the user to shoot cartridge (bullet) from the gun (1); - a gun (1) bolt (2), which moves backwards in the direction of gun's (1) stock with the explosion effect of the cartridge that comes out from the barrel when shooting is performed by pulling the trigger (4) and tends to move forward (to barrel) to take cartridge from the magazine by returning to its initial position after getting the rearward position; - a Lever-latch (3), which is positioned closer to the trigger (4) group of the gun (1) and moves slightly towards the trigger (4) (downwards) in a vertical direction when being pressed on the lever head (3.1) of the Lever-latch (3) and returns to its initial position after being released by means of the lever spring (3.3);
- at least one Lever-latch pin (3.2) on the Lever-latch
(3);
- a trigger pin (4.1), which is located on the upper side of the trigger (4) and prevents the trigger (4) to function by repressing by the Lever-latch (3) or the Lever-latch pin (3.2) when the Lever-latch (3) is in a pressed position; - a groove (2.1), which is on the gun (1) bolt (2) and ensures that the bolt (2) is captured rearward by the Lever-latch (3) by corresponding to the Lever-latch pin (3.2) at the end of the backward movement of the bolt (2) and the bolt (2) is released from the Lever-latch pin (3.2) to return its initial position when the user presses the Lever-latch (3)
An example operation of the present invention is as follows:
When the user presses the trigger (4), the gun (1) bolt (2) moves backwards by means of the energy of the cartridge after the explosion. When the bolt (2) is moved backwards and riches the Lever-latch (3), the Lever-latch pin (3.2) clings to the groove (2.1) of the bolt and holds the bolt (2) rearwards.
The user presses the lever head (3.1) of the Lever-latch (3) so that the bolt (2) is ready to shoot again. When the lever head (3.1) of the Lever-latch (3) is pressed, the Lever-latch (3) moves and the lever- latch pin (3.2) comes out from the bolt (2) groove (2.1). When the Lever-latch pin (3.2) comes out of the bolt (2) groove (2.1), the carrier latch carries the cartridge from the magazine and the bolt (2) inserts the cartridge into the chamber by moving forward and the gun (1) becomes ready for firing.
If the user continuously keeps pressed on the Lever-latch (3) which holds the bolt (2), the bolt (2) cannot remain rearwards and moves forward. However, in this case, the trigger pin (4.1) is clamped by the Lever-latch (3) and the movement of the trigger
(4) is prevented. Thus, the semi-automatic self-loading shooting cannot be performed.
