The present invention relates to projectile propelling systems or apparatus. More specifically, the present invention relates to ammunition magazines for projectile launchers, firearms, or paintball markers.
A conventional projectile propelling system, such as a firearm or a paintball marker, is able to fire or launch ammunition continuously as long as the ammunition is available. Ammunition, for example, can be bullets for hand guns or paintballs for paintball guns. To enhance firing power, a type of projectile propelling system employs a magazine which houses more ammunition. A conventional magazine, for example, is a container loaded with ammunition in such a way that, when the magazine is attached to a firearm, the ammunition in the magazine can be sequentially loaded to a firing chamber of a launcher by a loading mechanism before launching.
For an automatic or semi-automatic firing apparatus, a projectile chamber is fired when a trigger is pulled. As soon as a projectile is fired, a retract mechanism of a firearm, for example, reloads the next projectile or bullet from the magazine for the subsequent firing. As the firing speed increases, more ammunition is needed to maintain the firing power. When ammunition in the magazine depletes, the projectile propelling system stops firing until the empty magazine is replaced with a fully loaded magazine.
To supply and provide sufficient amount of ammunition, users or operators usually carry multiple loaded magazines with a finite amount of ammunition such as bullets or paintballs in each magazine. When ammunition inside a magazine depletes, the user replaces the magazine by removing the empty magazine from the projectile propelling system such as a gun and reattaches a fully loaded magazine before a projectile can be fired. Projectile propelling is interrupted or halted during the process of replacing a magazine. To minimize firing interruption from magazine replacement, reducing the frequency of magazine replacement as well as minimum effort of magazine replacement is essential.
A conventional bottom mounted ammunition magazine includes a single column of ammunition such as paintballs with a single supply port. When the single column of ammunition is exhausted, the magazine needs to be replaced. A problem associated with such a conventional ammunition magazine is that it holds a limited amount of ammunition or projectiles.
One embodiment of the present invention discloses a double-magazine (“Dmag”) capable of housing two columns of projectile ammunition with a controlled dispensing mechanism. Dmag, in one aspect, includes a first ammunition channel, a second ammunition channel, and a controlled dispensing mechanism. The controlled dispensing mechanism includes multiple flexible projectile control bars (“FPCBs”). The first ammunition channel contains a first set or column of projectiles and the second ammunition channel which is situated in parallel to the first ammunition channel is configured to house a second column of the projectiles.
Dmag also includes a follower with a follower lock capable of moving inside of the first ammunition channel. The follower is configured to push the first set of projectiles toward a first ammunition supply port of the first ammunition channel. The controlled dispensing mechanism uses one or more FPCBs to control projectiles from dispensing unless a switch, also known as magazine well (“mag-well”) release, is triggered. For example, each FPCB has a flexible flap which keeps the column of projectiles from dispensing or reaching to the loading port of the launcher until the release is triggered.

One embodiment of the present invention discloses a Dmag capable of housing two columns of projectile ammunition with a controlled dispensing mechanism. Dmag, in one aspect, includes a first ammunition channel, a second ammunition channel, and a controlled dispensing mechanism. The controlled dispensing mechanism includes multiple flexible projectile control bars (“FPCBs”). The first ammunition channel contains a first set or column of projectiles and the second ammunition channel which is situated in parallel to the first ammunition channel is configured to house a second set of projectiles.
Dmag also includes a follower with a follower lock capable of moving along the first ammunition channel. The follower is configured to push the first set of projectiles toward a first ammunition supply port of the first ammunition channel. The controlled dispensing mechanism uses one or more FPCBs to control projectiles from dispensing unless a switch, also known as mag-well release, is released. For example, each FPCB has a flexible flap which keeps a set of projectiles from dispensing or reaching to the loading port of the launcher until the follower lock or mag-well release is triggered.
Shell, in one example, is structured or organized to contain two columns or channels 102-104 wherein one end of channel is supply port 110 and the other end of channel is coupled to bottom plate 130. Each channel 102 or 104, also referred to as ammunition channel, is configured to have a column shape in which a column of projectiles 112 which is one projectile on top of another projectile is stored in the channel. The column of projectiles 112, in one aspect, is pushed or guided by a follower 116 with a spring force provided by a spring 118. In one aspect, follower 116 coupled to spring 118 is able to provide a predefined constant dispensing force or pressure that pushes projectiles toward to supply port 110.
When Dmag is coupled with a projectile launcher, not shown in
The projectile or ammunition can be any types of substance delivery capsules such as paintballs, lethal delivery capsules, non-lethal delivery capsules, chemical delivery balls, bullet, and the like. For example, paintballs usually include non-toxic, biodegradable, water soluble color substance wherein they leave colored marks upon breakage. A bullet, on the other hand, is generally made of cylindrical metal shell that can be expelled from a firearm, especially a rifle or handgun.
Each channel 102 or 104 includes a spring 118 wherein one end of spring 118 attaches to the bottom section of follower 116 while another end of spring 118 couples to bottom plate 130. When spring 118 can be flexibly compressed in accordance with the number of projectiles 112 in the channel, spring 118 generates a spring force pushing projectiles 112 away from bottom plate 130. Because of the constant spring force, projectiles 112 can easily reach to the loading port of a receiver passing through supply port 110 when Dmag is coupled to a launcher.
To store and control projectiles 112 from unintended dispensing from the Dmag, a locking mechanism 126 and FPCBs 106 are used to control or manage dispensing of projectiles to improve unintended dispensing of ammunition. For example, when FPCB 106 is in a looking position in response to gate lock or looking hook 126, flexible flap 108 of FPCB 106 leans over from the center of Dmag to the channel opening or supply ports 110 to block projectiles from leaving the channel 102 unless the lock is released or the mag-well release is triggered.
Upon triggering of the lock or mag-well release, FPCB 106 rolls down to retract (or remove) flexible flap 109 from covering a portion of supply port 110. Once flexible flap 109 rolls down or retracts, projectile 112 within channel 104 can freely move to the loading port of launcher for launching. A function of FPCB 106 is to keep or maintain the projectiles in the ammunition channel unless a user is ready to fire.
Dmag, in one embodiment, includes first ammunition channel 102, second ammunition channel 104, first followers 116, and FPCBs 106. First ammunition channel 102 is used to house a first column of projectiles 112 and second ammunition channel 104 houses a second column or set of projectiles 112. In one example, the projectiles are paintballs. Alternatively, the projectiles are breakable lethal delivery capsules. First follower 116 is able to move inside of first ammunition channel 102 to push the first column of projectiles toward a first ammunition supply port 110 for supplying ammunition.
First FPCB 106, which is situated adjacent to first ammunition channel 102, is configured to have a first flexible flap 108 to extend from one end of the first FPCB to the middle of supply port 110. Note that the first flexible flap is configured to keep the first set of projectiles from reaching loading port of a launcher until the first follower lock is released. First FPCB 106 is able to roll down toward or retract toward the bottom of Dmag for ammunition supply when the Dmag is engaged to a projectile launcher.
Dmag also includes a first spring 118, a shell 122, and a first gate lock 126 wherein the top end of first spring 118 attaches to the bottom side of first follower 116 and the bottom end of first spring 118 attaches to the bottom portion of first ammunition channel 102 or bottom plate 130. Shell 122 is structured in such a way that it houses first ammunition channel 102, second ammunition channel 104, and first FPCB 106. It should be noted that shell 122 can be structure to include more than two ammunition channels. The top end of shell 122 includes several supply ports and the bottom end of shell 122 contains one or more flanges used to facilitate engagement to bottom plate 130.
First gate lock 126 situated adjacent to bottom plate 130 is configured to lock first follower 116 in a predefined position within first ammunition channel 102. In one example, bottom plate 130 is formed by two or four substantially identical bottom pieces. Each of the bottom piece includes a locking hook or a groove. The bottom piece is attached to shell 122 by sliding the flange of shell 122 into the groove of bottom pieces to form a bottom plate 130.
Dmag further includes a second follower 116 and a second FPCB 106 for implementing second ammunition channel 104. Second follower 116, in one aspect, is able to move inside of second ammunition channel 104 to push the second column of projectiles 112 toward a second ammunition supply port 110 of second ammunition channel 104. Second FPCB 106, which is situated adjacent to first FPCB 106, is configured to have a second flexible flap 109 extending from one end of second FPCB 106. Second flexible flap 109 is configured to keep the second column of projectiles 112 from leaving second ammunition channel 104 until the mag-well release is triggered.
An advantage of using a Dmag is that Dmag provides two or more columns of ammunition to increase overall capacity of ammunition.
For example, during a loading process 202, a projectile 212 is pushed or loaded into ammunition channel 102 via supply port 110. When projectile 212 contacts with flexible flap 108, flexible flap 108, which is sufficient flexible, is bent into channel 102 whereby allowing projectile 212 to pass through supply port 110 for storage. Flexible flap 109, for example, is in a rolled down position whereby projectile 214 is free to leave ammunition channel 104.
It should be noted that the diagram 200 shows two-channel Dmag to simplify the illustration of the present embodiment of invention. Additional channels can be added to Dmag to further increase the ammunition capacity.
Dmag 504 illustrates shell 502, bottom plate 508, follower 116, spring 118, flexible flap 106, and a retracted flexible flap 516. In one aspect, FPCBs 106 are placed in the center part of shell 502 or Dmag 504. Alternatively, FPCBs 106 can also be placed at the edge of shell 502. Bottom plate 508 is attached to shell 502 via flange 506.
One advantage of employing Dmag is that it can be assembled or disassembled without use of tools.
Diagram 702, in one embodiment, illustrates an open view or a cutaway view of feed ramp 606 used to facilitate projectile dispensing, projectile loading, and FPCB movement. Feed ramp 606, which includes two supply ports 722 and two slots, is configured to fit inside of the shell. In one aspect, feed ramp 606 is situated on top of extruder 716 inside of the shell. Alternatively, extruder 716 is partially inserted into feed ramp 606 when both feed ramp 606 and extruder 716 are slide into the shell.
Diagram 704 shows a follower 116 having a hook 730, a projectile seat 732, and a spring anchor 734 wherein spring anchor 734 is used to attach to a spring. Hook 730, also known as follower lock, is used to keep follower 116 in a stationary position until hook 730 is released. Seat 732 is used in contact with a projectile. Upon release of hook 730, seat 732 pushes a column of projectiles toward the supply port of Dmag. Note that seat 732 is structured in a concave half-spherical shape to reduce the pressure to a round-shaped projectile(s) (i.e. paintball) to minimize projectile breakage during the process of pushing.
The exemplary embodiment of the present invention includes various processing steps, which will be described below. For example, in
At block 1604, after pushing or loading a projectile into the first ammunition channel against a spring force supporting the first follower and the first flexible flap for ammunition loading, the first flexible flap, at block 1606, is bent into the first ammunition channel whereby permitting the projectile to pass from the supply port and to be loaded into the first ammunition channel.
At block 1608, the process engages a second FPCB with a locking mechanism that allows a second flexible flap to cover at least a portion of second supply port of a second ammunition channel to prevent projectiles from leaving the second ammunition channel. Upon pushing or loading a projectile or projectiles into the second ammunition channel against a spring force supporting the second follower and the second flexible flap, the second flexible flap is forced to bend or curve into the second ammunition channel whereby allowing the projectile to pass from the second supply port to load the projectile into the second ammunition channel. After aligning the first supply port of the Dmag with a loading port of a launcher, the Dmag is inserted or plugged into the loading port or magazine well of the launcher. The process of plugging triggers release of a first mag-well release. Release of mag-well release causes a flexible flap of FPCB to roll down. Rolling down of the first FPCB means pulling the first flexible flap toward the bottom of the Dmag whereby allowing projectiles to be loaded into the loading port of the launcher. While the first channel is actively supplying ammunition to the launcher, the second FPCB keeps the projectiles in the second ammunition channel from leaving because the second mag-well release has not been triggered yet. The second mag-well release is associated with the second FPCB. After disengaging the Dmag from the launcher and realigning the second supply port of the Dmag with the loading port of the launcher, the Dmag is inserted into the loading port of launcher which triggers the second mag-well release. After the second flexible flap rolls down, the projectiles in the second ammunition channel is allowed to be loaded into the loading port of the launcher.
