Abstract

A frame assembly for a pistol with a lock lever. The frame assembly includes a lower frame having a grip and an upper frame assembled on the lower frame and to a slide. The lower frame has: a mounting projection projecting upward to face the upper frame; and a lever mounting unit separated from the mounting projection and projecting upward. The upper frame has: a mounting groove into which the mounting projection is inserted to face the lower frame, and a lever hooking hole at one side of the mounting groove. The lever mounting unit has a lock lever having one end locked to be rotatable by a lock pin and the other end elastically supported to project upward. When the upper frame is assembled to the lower frame, the other end of the lock lever is inserted into the lever hooking hole and the upper frame is locked.

Claims (32)

1. A frame assembly for a pistol with a lock lever, the frame assembly ( 1 ) comprising:

a lower frame ( 10 ) having a grip ( 11 ) formed at a lower side; and

an upper frame ( 20 ) that is assembled on the lower frame ( 10 ) and is assembled to a slide,

wherein the lower frame ( 10 ) has:

a mounting projection ( 15 ) which has a predetermined length and projects upward to a predetermined height in a direction to face the upper frame ( 20 ); and

a lever mounting unit ( 16 ) formed to be separated by a predetermined distance in a horizontal direction from the mounting projection ( 15 ) and project upward to a predetermined height,

wherein the upper frame ( 20 ) has:

a mounting groove ( 25 ) which has a predetermined depth and into which the mounting projection ( 15 ) is inserted in a direction to face the lower frame ( 10 ), and

a lever hooking hole ( 27 ) which has a predetermined depth at one side of the mounting groove ( 25 ), and

wherein the lever mounting unit ( 16 ) has a lock lever ( 40 ) having one end that is locked to be rotatable by a lock pin (P) and the other end that is elastically supported to project upward by an elastic spring (S), and when the upper frame ( 20 ) is assembled to the lower frame ( 10 ), the other end of the lock lever ( 40 ) is inserted into the lever hooking hole ( 27 ) and the upper frame ( 20 ) is locked.

2. The frame assembly for a pistol with a lock lever according to claim 1 ,

wherein the lower frame ( 10 ) and the upper frame ( 20 ) are screw-assembled by fastening a coupling screw (B) from an inner side of the upper frame ( 20 ) toward the lower frame ( 10 ).

3. The frame assembly for a pistol with a lock lever according to claim 1 ,

wherein the mounting projection ( 15 ) has fitting grooves ( 15 A) which have a predetermined depth and are formed along both side surfaces in a length direction of the mounting projection, and

wherein the mounting groove ( 25 ) has hook projections which project by a predetermined width and are formed along both side surfaces in a length direction of the mounting groove so as to be fitting-inserted into the fitting groove ( 15 A).

4. The frame assembly for a pistol with a lock lever according to claim 1 ,

wherein the grip ( 11 ) has mounting portions ( 12 ) which have a predetermined depth at both side surfaces along a vertical length of the grip, and

wherein the mounting portion ( 12 ) has a pair of grip panels ( 30 ) which are provided to be slid and fitting-assembled in a vertical direction.

5. The frame assembly for a pistol with a lock lever according to claim 1 ,

wherein the lower frame ( 10 ) is manufactured in a single type or a double type depending on a size of a magazine which can be mounted inside the lower frame,

wherein the upper frame ( 20 ) is manufactured to have a size of 4.25 in., 5 in., and 6 in. depending on a length of a gun barrel, and

wherein the lower frame ( 10 ) as any one selected from the single type and the double type and the upper frame ( 20 ) as any one selected from upper frames of 4.25 in. 5 in. and 6 in. are configured to be assembled together.

6. The frame assembly for a pistol with a lock lever according to claim 2 ,

wherein the mounting projection ( 15 ) has fitting grooves ( 15 A) which have a predetermined depth and are formed along both side surfaces in a length direction of the mounting projection, and

wherein the mounting groove ( 25 ) has hook projections which project by a predetermined width and are formed along both side surfaces in a length direction of the mounting groove so as to be fitting-inserted into the fitting groove ( 15 A).

7. The frame assembly for a pistol with a lock lever according to claim 2 ,

wherein the grip ( 11 ) has mounting portions ( 12 ) which have a predetermined depth at both side surfaces along a vertical length of the grip, and

wherein the mounting portion ( 12 ) has a pair of grip panels ( 30 ) which are provided to be slid and fitting-assembled in a vertical direction.

8. The frame assembly for a pistol with a lock lever according to claim 2 ,

wherein the lower frame ( 10 ) is manufactured in a single type or a double type depending on a size of a magazine which can be mounted inside the lower frame,

wherein the upper frame ( 20 ) is manufactured to have a size of 4.25 in., 5 in., and 6 in. depending on a length of a gun barrel, and
