Title: Lever action pump rifle

Description:
TECHNICAL FIELD 
     The invention relates to pump rifles used for hunting or similar purposes. 
     The invention particularly relates to an operation mechanism of a rifle wherein it relates to a lever action pump rifle pulling the trigger and setting a gun with a single hand without the use of a handguard. 
     BACKGROUND 
     As automated rifles used in the prior art feed barred into a new cartridge with pushing of gas, some amount of the energy resulting from the firing is transferred into the mechanism movement. This deteriorates the precision of the shot and decreases standoff distance. 
     In the prior art, collapsible and over-and-under rifles using the whole energy for shooting, at most two bullets can be used. This renders a hunter vulnerable in case of an attack by animals during hunting. 
     In pump rifle systems used in the prior art, the cartridge is fed by holding the grip with one hand and pulling the handguard with the other. This causes time loss and tires human. 
     As a result of the studies conducted on the literatures, various embodiments relating to said pump rifles are encountered. One of these is a utility model application with application number CN2008/02503 entitled “One-piece pump bolt handle”. The abstract of the invention states that “the invention relates to one-piece pump bolt handle performing charge-discharge procedure of the rifle in pump hunting rifle, wherein it consists of two arms and mechanism lower cover and the mechanism has the mechanism lower cover and the one-piece bolt handle on the mechanism lower cover and a pipe at the end of the bolt handle.” 
     Another example relating to said embodiment is a utility model application with application number CN2007/08067 entitled “Collapsible semi-automatic pump hunting rifle”. The Abstract of the invention states that “the invention has a guard leaning on shoulder used for hunting purposes, a rifle mechanism, a trigger enabling the shooting and a mechanism arm and a barrel; semi-automatic pump rifle comprises at least one demountable handguard located on the lower portion of said barrel and serving as an operating handle in order to enable carriage of said rifle, disassembly by collapsing for storage and functioning as serial and pump rifle; at least one operation arm moving on said operating handle and having a pump operation button; at least one lower case body carrying the trigger group and having a trigger group disposed therewithin; at least one upper case body carrying the rifle mechanism; at least one butterfly enabling integration by the upper case body key; and at least one trigger group on the charger tube. 
     Consequently, improvements are performed in parallel with improving technology in pump rifles, thus new embodiment are required to eliminate disadvantages mentioned above and provide solutions to present systems.

     DETAILED DESCRIPTION OF THE INVENTION 
     In this detailed description, preferred embodiments of the lever action rifles ( 70 ) of the invention is explained merely for better understanding of the subject and to form no restrictive effect. 
     The rifle ( 70 ) has the butt ( 6 ) providing support on shoulder during shooting and a charger tube ( 8 ) having cartridge storage; and the barrel ( 9 ) located for shooting of said cartridge. The handguard ( 10 ) hiding the heat of the barrel ( 9 ) during shooting and held for a more balanced shooting comprises the carrier ( 41 ) where the cartridge moving from said charger tube ( 8 ) to the barrel ( 9 ) stands. It consists of the trigger ( 42 ) initiating firing of the cartridge fed to said barrel and the firing pin ( 28 ) hitting on the rear portion of the cartridge in line with the barrel ( 9 ) connected to said trigger. The mechanism ( 20 ) containing said firing pin ( 28 ) has the arm ( 61 ) on which said mechanism ( 20 ) is located. It comprises the lever arm ( 26 ) performing the operating procedure of the rifle by enabling the feeding of the cartridge from the charger tube ( 8 ) to the barrel ( 9 ); the operating handle ( 50 ) connected to said lever arm ( 26 ) and operating the rifle with movement in A and A′ direction; the lever arm sliding channel ( 43 ) enabling the sliding of the lever arm ( 26 ) on said operating guard ( 44 ) in B and B′ direction. 
       FIG. 1  shows assembled perspective view of the lever action rifle ( 70 ) of the invention. The rifle ( 70 ) consists of the main parts of the butt ( 6 ), the operating handle ( 50 ), the trigger group ( 40 ), the carrier ( 41 ), the mechanism ( 20 ), the main body ( 1 ), the handguard ( 10 ), the barrel ( 9 ) and the charger tube ( 8 ). Furthermore, the rear sight ( 3 ), the eye ( 14 ) and the flash hider ( 15 ) are mounted on the barrel ( 9 ). 
       FIG. 2  is perspective view of the disassembled rifle ( 70 ) of the invention. As seen in the figure, the butt ( 6 ) is attached to the main body ( 1 ) with a butt connection_bolt ( 7 ). The operating handle ( 50 ) and the trigger group ( 40 ) is assembled to the lower portion of the main body ( 1 ). The barrel ( 9 ) and the charger tube ( 8 ) are assembled to the inner portion of the main body ( 1 ) such that the barrel ( 9 ) is on top. Afterwards, the handguard ( 10 ) is attached on the charger tube ( 8 ) with the handguard connection_nut ( 11 ), the ring ( 12 ), and the barrel tightening nut ( 13 ). 
       FIG. 3  shows a detailed perspective view of the lever arm ( 26 ), the mechanism ( 20 ) and the operating handle ( 50 ) of assembled rifle ( 70 ) of the invention. 
     The mechanism ( 20 ) has the parts of the lock ( 22 ), the cartridge puller knockout pin ( 23 ), the cartridge puller ( 24 ) and the firing pin ( 28 ).  FIG. 6  shows assembled perspective view of the mechanism ( 20 ), the lever arm ( 26 ) and the arm group ( 60 ). As seen in the figures, the mechanism body ( 21 ) is seated on upper portion of the arm ( 61 ). Again, the lever atm ( 26 ) is fixed to the arm connection_bed ( 62 ) on the arm ( 61 ). This procedure is by means of the lever arm connection_bolt ( 27 ). 
     The lever arm ( 26 ) is connected from the other side to the operating handle ( 50 ). During this procedure, the operating handle pulley ( 29 ) is attached to the lever arm sliding channel ( 43 ), and secured with the pulley connection_bolt ( 25 ). The operating handle ( 50 ) is secured to the trigger body ( 54 ) with the operating handle connection_member ( 53 ). Also, the trigger ( 42 ) is assembled on the trigger body ( 54 ). 
     The lever arm lower boundary pulley ( 46 ) and the lever arm upper boundary pulley ( 48 ) which restrict the movement of the lever arm ( 26 ) are secured on the main body ( 1 ). This securing procedure is by means of the lever arm upper boundary pulley pin ( 47 ) and the lever arm lower boundary pulley pin ( 45 ). 
     Another part restricting the movement of the lever arm ( 26 ) when the rifle ( 70 ) is operated is the lever arm rear restriction pulley ( 4 ) secured to the main body ( 1 ) with the lever arm rear restriction pulley connection_pin ( 5 ). 
     It consists of the parts of the operating handle ( 50 ), the operating handle guard ( 44 ) and the operating handle grip ( 51 ). On the inner portion of the operation handle grip ( 51 ), there is the finger protection member ( 49 ), thereby preventing injuries that may occur during the operation procedure. 
     There is the cartridge discharge opening ( 2 ) where the cartridge corresponding to the upper portion of the carrier ( 41 ) portion in the main body ( 1 ) leaves the rifle ( 70 ). For the movement of said carrier ( 41 ), the hammer ( 52 ) connected to the arm ( 61 ) is secured to the main body ( 1 ). There is the mechanism hammer connection clearance ( 63 ) on which said hammer ( 52 ) is connected to the mechanism body ( 20 ). 
     Operation Principle: 
     For the operation of the rifle ( 70 ) in normal position, the operating handle ( 50 ) is held from the operating handle grip ( 51 ) and moved in the operation direction (A). During this procedure, the operating handle ( 50 ) rotates from M 1 ; the portion of the arm ( 61 ) secured to the arm connection_bed ( 62 ) of the arm located on the mechanism ( 20 ) of the lever arm ( 26 ) rotates in M 2  axis. The operating handle pulley ( 29 ) slides in downward direction (B) in the lever arm sliding channel ( 43 ). Proceeding of the operating handle ( 50 ) in the operation direction (A) terminates with the contact of the lever arm ( 26 ) to the lever arm lower boundary pulley ( 46 ). As the upper portion of the lever arm ( 26 ) is connected to the mechanism body ( 21 ), downward movement (B) of the lever arm ( 26 ) moves the mechanism ( 20 ) in mechanism tensioning direction (C). As a result of this procedure, the cartridge from the charger tube ( 8 ) falls into the carrier ( 41 ). With the help of  FIG. 4 , procedures explained in this paragraph will be clearly understood. 
     In this position, the system may be locked by means of the lock ( 22 ) on the mechanism body ( 21 ). 
     Afterwards, movement is initiated in the operating handle ( 50 ) settlement direction (A′). As explained above, the operating handle ( 50 ) rotates in M 1  axis and the lever arm ( 26 ) in M 2  axis. Other end of the lever arm ( 26 ) proceeds in upward movement direction (B′) with the slide of the operating handle pulley ( 29 ) in the lever arm sliding channel ( 43 ). Here, the lever arm ( 26 ) moves the mechanism ( 20 ) in the feeding direction (C′). During this movement, the mechanism body ( 21 ) is connected to the hammer ( 52 ) from the mechanism hammer connection clearance ( 63 ). The hammer ( 52 ) rotates the carrier ( 41 ) in M 3  axis, and moves the carrier in the feeding direction (D). With this movement of the carrier ( 41 ), the cartridge on the carrier ( 41 ) is fed into the muzzle ( 16 ). With the movement of the mechanism ( 20 ) in the feeding direction (C′) and feeding of the cartridge into the mu771e ( 16 ) are simultaneous. The cartridge coining into the muzzle ( 16 ) enters into the barrel ( 9 ) with pushing of the mechanism body ( 21 ) moving in the feeding direction (C).  FIG. 5  is a perspective view of the cartridge provision into the barrel ( 9 ). 
     Movement of the operating handle ( 50 ) in the settlement direction (A′) terminates with the contact of the lever arm ( 26 ) with the lever arm upper boundary pulley ( 4 . 8 ) and the lever arm rear restriction pulley ( 4 ). 
     Lastly, the firing pin ( 28 ) which is free with the push on the trigger ( 42 ) hits the cartridge, thereby enabling the shooting. After the shooting, the mechanism ( 20 ) moves in the tensioning direction with the movement of the operating handle ( 50 ) in the operation direction (A) again. Meanwhile, empty cartridge is discarded out of the rifle from the cartridge discharge opening ( 2 ) by means of the cartridge puller ( 24 ). 
     Protection scope of this application is stated in claims and cannot be restricted to what is explained above with the purpose of exemplification. Novelty of one skilled in the art revealed in the invention can apparently be applied on other fields with similar purpose.
