Lock mechanism of a trigger group that enables assembly and disassembly of a gun

Abstract

A lock system which is included in shotguns that are used by hunters to hunt game animals, characterized in that it is developed to provide safety storage by disassembling the trigger group from the case when the gun is not used and to provide the trigger group to be easily mounted on the case when the gun is used. This provides easy assembly and disassembly procedures of the trigger group on the case via a lock bolt gap, a contact surface and a locking point created on the case belonging to the gun. A stop gap, fitting surface, lock bolt gap, vertical surface, assembly gap, positioning gap and operating gap are created on the trigger guard of the trigger group. A lock bolt contacted with a cap pin extends through the assembly gap by positioning in the lock bolt gap created on the trigger group.

DETAILED DESCRIPTION OF THE INVENTION

(11) FIG. 1 is a mounted and sectional side view of the case (100) belonging to a shotgun used by hunters to hunt game animals, and the trigger guard (210) belonging to the trigger group (200) and lock system (300), which is the topic of the invention.

(12) During the production process of the invention developed for providing safety storage by disassembling the trigger group (200) through the case (100) in cases where the gun is not used and for mounting the trigger group (200) on the receiver (100) when the gun is used: lock bolt gap (102), the contact surface (103) and locking point (104) were created in the case (100); and stop gap (211), fitting surface (212), lock bolt gap (213), vertical surface (214), assembly gap (215), positioning gap (216) and operating gap (217) were created on the trigger guard (210) of the trigger group (200).

(13) The lock system (300), which provides for easy assembly and disassembly of the trigger group (200) on the case (100) via lock bolt (310) contacted with capped pin (360) extending through the assembly gap (215) by positioning to the lock bolt gap (213) created on the trigger guard (210) belonging to the trigger group (200), consists of: assembly gap (215), pin clearance (311) and lock rim (312) located on lock bolt (310), intermediate member (320) found on assembly gap (215), surface (321) and side pressure surface (322), lock switch (330) having an upper surface (331) and a subsurface (332), pin (340) connected with pin gap (311) found in lock bolt (310), sear spring (350) enabling the lock bolt (310) or lock system (300) to be in the forward position, thus to be active by means of stretched position, capped pin (360) providing the connection of the lock system (300) with the trigger guard (210).

(14) In the mounting process of the lock system (300) to the trigger guard (210), lock switch (330) is positioned to the positioning gap (216) on the trigger guard (210) so as to move the upper part of the lock system on the operating gap (217). Cap pin (360) is mounted by extending through the assembly gap (215) after the intermediate member (320), lock bolt (310) and sear spring (350) concerning the lock system (300) are positioned on the lock bolt gap (213). At this stage, the lock system (300), since one end point of the sear spring (350) contacts with the vertical surface (214) and another end point of the sear spring contacts with the pin (340) on the lock bolt (310), the lock bolt (310) is pushed forward, thus the lock system (300) is in the locking position.

(15) Mounting of the trigger guard (210) to the receiver (100) through the lock system (300) which is the topic of the invention is provided as shown in FIG. 4. In this process, stop gap (211) on the trigger guard (210) is screwed to the stop (101) on the receiver (100). Later, locking point (312) is provided to screw through the lock bolt gap (102) by overcoming the power of the sear spring (350) of the lock bolt (310) after the trigger guard (210) is pushed upward to the case (100). At the same time, the lock rim (312) presses the locking point (104). At this point, fitting surface (212) on the trigger guard (210) contacts with the contact surface (103) on the case (100), locking is enabled, and the gun is now ready to use.

(16) The trigger group (200) must be disassembled from the case (100) to eliminate accidental risk in the cases where the gun is not used. This process, which includes the disassembly of the trigger group (200) from the case (100), is shown representatively in FIG. 7.

(17) In the process specified, the hunter pushes the lock switch (330) by pushing it from the subsurface (332) upward. Intermediate member (320) contacts with the lower pressure surface (321) to the upper surface (331) of the lock switch (330) moving through the operating gap (217) moves around the axis of the cap pin (360) and therefore, it pushes the pin (340) on the lock bolt (310) via side pressure surface (322). As a result of the movement of the pin (340), the lock bolt (310) is enabled to be disassembled from the lock rim (312) thus, lock bolt gap (102) by overwhelming the sear spring (350). In this case, the trigger guard (210) is moved to the bottom, stop guard (211) is separated from the stop (101), so the trigger group (200) is easily disassembled from the case (100).

(18) By means of the lock system (300) which is the topic of the invention, the trigger group (200) can be kept by easily disassembling from the case (100) in cases where the gun is not used as stated above. Therefore, it was provided to prevent the gun from firing and to eliminate the accidents that may be experienced in situations where the kids play with a gun.
