System for loading a paintball
View Patent ↗The plural option loading system for a pneumatic gun. The pneumatic gun has a receiver with the first and second loading port disposed to permit loading either by gravity or forced loading such as from a magazine. The barrel can be locked to the receiver to permit loading through only one of the two ports depending on the orientation in which it is locked to the receiver and permits selective loading through only a selected port at any time.
1. A pneumatic gun comprising:
a receiver having a first loading port and a second loading port; and
a barrel lockable to the receiver to permit loading only through the first port in a first orientation and only through the second port in a second orientation wherein the barrel manually moveable without tools between the first and the second orientation while the magazine is installed.
2. The pneumatic gun of claim 1 , wherein the barrel has a proximal end and a distal end, the barrel defining an aperture adjacent to the proximal end and a circumferential channel also adjacent to the proximal end, the channel defining a first locking point and a second locking point.
3. The pneumatic gun of claim 2 , further comprising a detent coupled to the receiver and residing in the channel and biased to engage the locking points, wherein when the detent engages the first locking point, the aperture aligns with the first port and when the detent engages the second locking point the aperture aligns with the second port.
4. The pneumatic gun of claim 2 wherein the barrel further defines an entry channel longitudinally disposed and connecting the circumferential channel with the proximal end.
5. The pneumatic gun of claim 3 , further comprising a bias spring to bias the detent into engagement.
6. The pneumatic gun of claim 1 , wherein the first port permits gravity loading of a projectile and the second port permits force loading of a projectile.
7. The pneumatic gun of claim 2 , wherein the locking points comprise rounded depressions in the floor of the circumferential channel.
8. The pneumatic gun of claim 7 , wherein the detent has a rounded engagement surface to engage the rounded depressions.
9. A method of loading a pneumatic gun comprising:
selecting between a plurality of loading ports in a receiver;
manually, without tools, twisting a barrel of the pneumatic gun to align an aperture in the barrel with a selected port while a magazine is installed in the receiver; and
locking the barrel with the aperture aligned with the selected port.
10. The method of claim 9 , wherein locking comprises:
engaging a locking point on the barrel with a detent on the receiver.
11. The method of claim 9 , further comprising:
gravity feeding a paintball into the barrel when the first port is selected; and
magazine feeding a paintball into the barrel when second port is selected.
