Description
- The present invention relates to gun technology, and more particularly to a magazine locking structure for gun, which allows the user to unlock the magazine from the gun by either a front operating mode or a rear operating mode.
- The
magazine 10 of a big gun (seeFIG. 1 ) is mounted at the main gun body "a" in front of thegrip 20, and detachably secured to the main gun body "a" by a magazine locking device "b". The magazine locking device "b" comprises alocking member 30 and aspring member 303. Thelocking member 30 is mounted at one lateral side of the main gun body "a", comprising apress rod portion 301 and alocking rod portion 302 connected at right angles. Thepress rod portion 301 is supported on thespring member 303 that is mounted within the main gun body "a". Normally, thepress rod portion 301 is not pressed by an external force, and thelocking rod portion 302 is help in aretaining groove 101 to lock themagazine 10 to the main gun body "a". Once thepress rod portion 301 is pressed by a user, thelocking rod portion 302 is immediately forced out of theretaining groove 101 by thespring member 303, allowing removal of themagazine 10 from the main gun body "a". - Subject to gun function design considerations, a gun can be configured having the
magazine 10 mounted in the main gun body "a" at a rear side relative to the grip 20 (seeFIG. 2 ). Themagazine 10 can be detached from the main gun body "a" in the same manner as shown inFIG. 1 . However, this prior art gun design has drawbacks as follows: - 1. The
magazine 10 is disposed near therear gun butt 40 and kept near the user's body. Because thelocking member 30 is not in the front sightline, the other hand (normally the left hand) of the user that is not holding thegrip 20 cannot press thepress rod portion 301 easily and rapidly when going to replace themagazine 10, complicating themagazine 10 mounting and dismounting procedures. - 2. When going to replace the
magazine 10, the user needs to put down the gun, and then pick up the gun for firing after replacement of themagazine 10. The application of this design of gun causes inconvenience and lacks mobility. - The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a magazine locking structure for gun, which eliminates the magazine replacement problems of prior art designs and facilitates mounting and dismounting of the magazine.
- To achieve this and other objects of the present invention, a magazine locking structure of the present invention is mounted in a gun. The gun comprises a main gun body equipped with a grip, and a magazine detachably mounted in the main gun body at a rear side relative to the grip. The magazine defines a retaining groove. The magazine locking structure comprises a locking member mounted at one lateral side of the main gun body adjacent to the magazine, and a first spring member supporting the locking member. The locking member has two opposite ends thereof respectively terminating in a press rod portion and a locking rod portion. The press rod portion has an inner side thereof connected to and supported on the first spring member in such a manner that the locking rod portion is held in the retaining groove of the magazine to lock the magazine to the main gun body when the press rod portion receives no pressure; the locking rod portion is forced out of the retaining groove of the magazine to unlock the magazine from the main gun body when the press rod portion is pressed by an external force. The magazine locking structure further comprises a spring-loaded button set and a link. The spring-loaded button set and the link are mounted within the main gun body. The spring-loaded button set comprises a press block and an actuation rod. The press block is transversely inserted through the main gun body and alternatively movable leftward and rightward relative to the main gun body. The actuation rod is mounted in the press block, and movable by the press block to carry the link alternatively forward and backward. The link comprises a rear lug located at a rear side thereof and abutted at an inner side of the locking member. The rear lug is adapted to force the locking rod portion of the locking member out of the retaining groove of the magazine, and to further unlock the magazine from the main gun body when the actuation rod is forced to carry the link forward, and to let the locking rod portion of the locking member be forced into the retaining groove of the magazine and to further lock the magazine to the main gun body when the actuation rod is forced to carry the link backward.
- Further, the spring-loaded button set is mounted in the main gun body at a front side relative to the grip. The press block comprises an oblique left slot and an oblique right slot disposed in a symmetric manner and linked to each other. The actuation rod is accommodated in between the oblique left slot and the oblique right slot when the press block is not pressed, and is forced into the oblique right slot when the press block is pushed leftward relative to the main gun body by an external force, or into the oblique left slot when the press block is pushed rightward relative to the main gun body by an external force.
- Preferably, the spring-loaded button set further comprises a push block and two second spring members. The push block has a front end thereof fixedly connected to the press block. The two second spring members are respectively mounted at opposing left side and right side of the push block, and adapted to push the press block back to the position where the actuation rod is kept in between the oblique left slot and the oblique right slot after the press block having been pushed leftward or rightward relative to the main gun body.
- Further, the actuation rod comprises a top extension portion upwardly extended out of the press block. The link further comprises a side lug transversely extended from one side of a front end thereof and fixedly connected to the top extension portion of the actuation rod.
- Preferably, the link further comprises an oblong horizontal slot located at a middle part thereof and horizontally slidably coupled to a guide rod of the main gun body.
- Preferably, the press block further comprises a locating groove located at a rear side thereof. The push block has a front end thereof fixedly connected to the locating groove of the press block.
- Preferably, the locking member further comprises a beveled guide edge located at an inner side of the locking rod portion and abutted against the rear lug of the link so that the locking rod portion of the locking member is movable out of the retaining groove of the magazine by the rear lug when the actuation rod carry the link forward.
- In conclusion, the invention provides a magazine locking structure for use in a gun where the magazine is mounted at the main gun body at a rear side relative to the grip. By means of the functioning of a spring-loaded button set and the functioning of a link that is coupled between the spring-loaded button set and a locking member of the magazine locking structure, the magazine can be conveniently unlocked from the main gun body either by pressing the rear-sided locking member or pushing a front-sided push block of the magazine locking structure.

FIG. 3 , a magazine locking structure C in accordance with the present invention is shown installed in a gun. The gun comprises a main gun body A and a magazine B. The main gun body A comprises a grip A1, a trigger A2 disposed at a front side relative to the grip A1 (seeFIG. 4 ), a trigger holder A3 disposed around the top side of the grip A1 (seeFIG. 3 ), a front block A4 fixedly located at the front side of the trigger holder A3, and a cover plate A5 connected to the top side of the front block A4. The cover plate A5 defines a notch A51 at the front side thereof. The magazine B is mounted in the main gun body A at a rear side relative to the grip A1, defining a retaining groove B1. Further, the magazine locking structure C comprises a lockingmember 1, a spring-loaded button set 2, and alink 3. - The locking member 1 (see
FIG. 3 ) is mounted at one lateral side of the main gun body A adjacent to the magazine B, having two opposite ends thereof respectively terminating in apress rod portion 11 and a lockingrod portion 12. Thepress rod portion 11 has its inner side connected to and supported on afirst spring member 13. Thus, when thepress rod portion 11 is not pressed, the lockingrod portion 12 is held in the retaining groove B1 of the magazine B (seeFIG. 9 ) to lock the magazine B to the main gun body A. On the contrary, when the user presses the press rod portion 11 (seeFIG. 10 ), the lockingrod portion 12 is forced out of the retaining groove B1 to unlock the magazine B from the main gun body A, allowing removal of the magazine B from the main gun body A. - The spring-loaded button set 2 (see
FIG. 3 ) is mounted within the main gun body A at a front side relative to the grip A1, comprising apress block 21, anactuation rod 22, apush block 23, and two second spring members 24 (seeFIG. 5 ). Thepress block 21 is transversely movably inserted through the main gun body A, i.e., the opposing left and right ends of thepress block 21 respectively protrude over the opposing left and right sides of the main gun body A (seeFIG. 7 ) and thepress block 21 can be pushed leftward or rightward relative to the main gun body A. Further, thepress block 21 is disposed at a front side relative to the trigger holder A3 (seeFIG. 5 ), defining an obliqueleft slot 211 and an obliqueright slot 212 disposed in a symmetric manner and linked to each other and a locatinggroove 213 located at a rear side thereof. Theactuation rod 22 is pivotally mounted in thepress block 21. When thepress block 21 is not pressed (seeFIG. 7 ), theactuation rod 22 is accommodated between the obliqueleft slot 211 and the obliqueright slot 212; when the user pushes thepress block 21 leftward (seeFIG. 8 ), theactuation rod 22 will be forced into the obliqueright slot 212; on the contrary, when the user pushes thepress block 21 rightward, theactuation rod 22 will be forced into the oblique left slot 211 (not illustrated). Further, theactuation rod 22 comprises atop extension portion 221 protruding over the top side of thepress block 21 and engaged into the notch A51 of the cover plate A5 (seeFIG. 6 ). Further, thepush block 23 is supported on the front block A4 below the cover plate A5, having its front end tightly secured to the locatinggroove 213 of thepress block 21. The twosecond spring members 24 are respectively mounted at opposing left side and right side of thepush block 23. After thepress block 21 having been pushed leftward or rightward, the elastic potential energy of the correspondingsecond spring member 24 immediately pushes thepress block 21 back to its former position where theactuation rod 22 is kept in between the obliqueleft slot 211 and the obliqueright slot 212. - The link 3 (see
FIG. 3 ) is mounted within the main gun body A, comprising aside lug 31 transversely extended from one side of a front end thereof, arear lug 32 downwardly extended from an opposing rear end thereof, and an oblonghorizontal slot 33 located at a middle part thereof and horizontally slidably coupled to a guide rod A6 of the main gun body A. Theside lug 31 is fixedly connected to thetop extension portion 221 of theactuation rod 22, enabling thelink 3 to be moved synchronously with theactuation rod 22 when the user pushes thepress block 21 leftward or rightward. Therear lug 32 is disposed at an inner side relative to the locking member 1 (seeFIG. 9 ). When the user pushes thepress block 21 leftward or rightward to move theactuation rod 22 into the obliqueleft slot 211 or oblique right slot 212 (FIG. 8 illustrates theactuation rod 22 moved into the oblique right slot 212), thelink 3 is carried forward by theactuation rod 22, causing therear lug 32 to push the lockingrod portion 12 of the lockingmember 1 out of the retaining groove B1 of the magazine B (seeFIG. 10 ) for allowing removal of the magazine B from the main gun body A. When the external force is released from thepress block 21, theactuation rod 22 is immediately returned to the position between the obliqueleft slot 211 or oblique right slot 212 (seeFIG. 7 ) to carry thelink 3 backward, thereby causing the lockingrod portion 12 of the lockingmember 1 to be engaged into the retaining groove B1 of the magazine B to lock the magazine B to the main gun body A again (seeFIG. 9 ). - Further, the locking
member 1 comprises abeveled guide edge 121 located at an inner side of the lockingrod portion 12 and abutted against therear lug 32 so that the lockingrod portion 12 of the lockingmember 1 can be pushed out of the retaining groove B1 of the magazine B by therear lug 32 when thelink 3 forward (seeFIG. 10 ). - As stated above, when going to dismount the magazine B, the user can directly press the
press rod portion 11 of the lockingmember 1, enabling the lockingrod portion 12 to be forced out of the retaining groove B1 of the magazine B. Alternatively, the user can push thepress block 21 of the spring-loaded button set 2 to move theactuation rod 22, thepush block 23 and thesecond spring members 24 and to further shift thelink 3 forward (seeFIG. 8 ) or backward. When thelink 3 is moved forward (seeFIG. 8 ), therear lug 32 will push the lockingrod portion 12 of the lockingmember 1 in direction away from the retaining groove B1 of the magazine B (seeFIG. 10 ), thereby unlocking the magazine B from the main gun body A, i.e., the user can operate the spring-loaded button set 2 to drive thelink 3 to move lockingmember 1 in direction away from the magazine B, thereby unlocking the magazine B from the main gun body A. Therefore, the invention effectively eliminates the drawbacks of the conventional designs. - Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
