Abstract: A projectile launcher includes a receiver and a dual cylindrical-shaped magazine (“DCM”) wherein the receiver contains a propelling mechanism and an ammunition receiving port. The propelling mechanism is used for launching a projectile. The ammunition receiving port, which may be situated at bottom of the receiver, is able to receive projectiles. It should be noted that the projectile launcher can also be a gun or firearm. The DCM includes two canisters and an ammunition supply port which is situated between the two canisters. The DCM carries multiple projectiles in such a way that a first portion of projectiles moves toward the receiver against gravity for supplying projectiles from the ammunition supply port to the ammunition receiving port while a second portion of projectiles move in a direction parallel to the receiver for replenishing projectiles from the second portion of projectiles to the first portion of projectiles.

Abstract: A projectile launcher using a self-resetting trigger system includes a striker, a sear, and a trigger. The striker, also known as hammer, includes an anchoring notch and is able to slide between a firing position and a ready-for-firing position for launching an object. The sear, which is substantially L-shaped sear, has a first sear end and a second sear end wherein the sear maintains the striker to the ready-for-firing position when the first sear end engages with the anchoring notch of the striker. The trigger, which is capable of self resetting independent from the movement of the striker, contains an elastic lip with a ramp and is able to maintain the sear in a ready position when the elastic lip and the second sear end are coupled in a lock position.

Abstract: A projectile launching device such as a paintball gun capable of firing a paintball using a hammer is disclosed. The paintball gun, in one embodiment, includes a bolt, a valve, and a hammer wherein the bolt has an air channel and is able to move within a bolt chamber. The valve, which is situated in a firing control chamber arranged in parallel to the bolt chamber, controls pressurized gas. The hammer, in one aspect, includes a pivot hole capable of hosting a pivot pin which facilitates a swing motion for the hammer. When the hammer swings around the pivot hole, the hammer contacts the valve whereby a portion of the pressurized gas is release. The bolt further includes a hammer reset element which is able to reset the hammer to a ready for firing position during a launch process.

Abstract: A projectile launcher having an upper receiver capable of swinging away from a lower receiver is disclosed. In one aspect, the lower receiver having a first end and a second end contains a firing control chamber. While the second end is located closer to barrel of the launcher, the first end of launcher is located closer to a buttstock. The firing control chamber includes a gas channel, wherein one end of gas channel is coupled to a valve and another end of gas channel reaches to the top of external wall of the chamber. The upper receiver having a first end and a second end contains a bolt chamber. The second end of upper receiver and the second end of lower receiver are pivotally coupled whereby allowing the first end of upper receiver to be pivotally swung away from the first end of lower receiver.

Abstract: A paintball propelling device capable of propelling paintballs using bottom feed magazine is disclosed. The paintball propelling device, in one embodiment, includes a receiver and a bottom feed magazine. The receiver, for example, has a top surface facing upward and a bottom surface facing downward at the ground, wherein the bottom surface of the receiver includes a bottom feed port. The bottom feed magazine provides paintballs to the receiver via a bottom feed port of the receiver. The bottom feed magazine, in one aspect, includes a feed tube, an L-shaped tube, and one-way paintball stopper. The feed tube transfers the paintballs from the bottom or floor of the bottom feed magazine to the top of the bottom feed magazine. The L-shaped tube assists to transfer paintballs from paintball reservoir to the feed tube. The one-way paintball stopper is configured to hold paintballs from leaving the feed tube back to the paintball reservoir.

Abstract: A paintball assembly capable of retaining a paintball in a loading chamber using a paintball catcher is disclosed. The paintball assembly includes a loading chamber, a detent, and a bolt. The loading chamber is coupled to a loading port to receive paintballs. In one embodiment, the detent includes a paintball catcher capable of catching the paintball as it is loaded into the loading chamber. In one example, the paintball catcher is a flexible paintball catcher extending into the loading chamber and is able to catch the paintball and hold it in a predefined position. When a trigger is pulled, the bolt pushes the paintball into a firing chamber while the paintball catcher releases the paintball.
