Magnetic drive bypass system for paintball loader
View Patent ↗A drive system for a regulating the rotation of a drive system or agitator in a paintball loader is disclosed. It is designed to regulate the rotation of a feeder, especially during a jam or when projectiles in a hopper become misaligned. This allows a user to quickly and effectively clear a jam and resume or continue rapid fire without damaging projectiles, the loader or the paintball marker.
1. A paintball loader comprising:
a loader body having an interior area for receiving a plurality of paintballs, an exit opening, and an outfeed tube in communication with the exit opening and configured to communicate with the infeed portion of a paintball gun;
a drive shaft, rotatable about a central axis, having first and second ends and having at least one magnetic portion adjacent the second end; and,
a paintball feed mechanism that moves paintball toward the exit opening, rotatable about the central axis and including at least one magnetic or magnetically attractable portion positioned to come into proximity with the at least one magnetic portion so that the paintball feed mechanism is releasably magnetically coupled for movement with the drive shaft.
2. The paintball loader of claim 1 , further comprising a motor coupled to the first end of the drive shaft.
3. The paintball loader of claim 2 , further comprising a controller in operative communication with the motor.
4. The paintball loader of claim 3 , further comprising a sensor in operative communication with the controller.
5. The paintball loader of claim 3 , wherein the rotation of the drive shaft is reversible.
6. The paintball loader of claim 1 , wherein the drive shaft remains rotatable if the paintball feed mechanism is prevented from rotating.
7. The paintball loader of claim 1 , wherein the paintball feed mechanism comprises a base portion which includes the at least one magnetic or magnetically attractable portion.
8. The paintball loader of claim 1 , wherein the paintball feed mechanism further comprises: an impeller portion and a drive spring having a first end and a second end, the first end of the drive spring coupled to the impeller portion; and a base portion having a magnetic or magnetically attractable portion and is coupled to the second end of the drive spring, the base portion being operable to wind the drive spring.
9. The paintball loader of claim 1 , wherein magnetic attractive forces between the at least one magnetic portion of the drive shaft and the at least one magnetic or magnetically attractable portion of the paintball feed mechanism is less than a rupture force of a paintball adapted to be loaded by the paintball feed mechanism.
10. A paintball loader comprising:
a paintball loader body for housing a plurality of paintballs;
a drive shaft within the loader body rotatable about a central axis having a keyed portion;
a clutch plate, having a mating keyed opening mounted on the drive shaft, the clutch plate including at least one first magnetic element, the keyed opening matingly engaged with the keyed portion of the drive shaft; and
a paintball feed mechanism rotatable about the central axis adjacent to the clutch plate, the paintball feed mechanism including at least one of a second magnetic element or magnetically attractable element attractable to the first magnetic element.
11. The paintball loader of claim 10 , further comprising a motor coupled to the drive shaft.
12. The paintball loader of claim 11 , further comprising a controller in operative communication with the motor.
13. The paintball loader of claim 12 , further comprising a sensor in operative communication with the controller.
14. The paintball loader of claim 13 , wherein the rotation of the drive shaft is reversible.
15. The paintball loader of claim 10 , wherein the drive shaft remains rotatable if the paintball feed mechanism is prevented from rotating.
16. The mechanism paintball loader of claim 10 , wherein the paintball feed mechanism comprises a base portion which includes the at least one of a second magnetic element or magnetically attractable element.
17. The paintball loader of claim 10 , wherein the paintball feed mechanism further comprises: an impeller portion and a drive spring having a first end and a second end, the first end of the drive spring coupled to the impeller portion; and a base portion which includes the at least one of a second magnetic element or magnetically attractable element and is coupled to the second end of the drive spring, the base portion being operable to wind the drive spring.
18. A method for driving paintballs in a paintball loader comprising the steps of a) providing the paintball loader, comprising a loader body incorporating a including: i) a drive shaft rotatable about a central axis having at least one first magnetic element; ii) a paintball feed mechanism mounted for rotation about central axis and having at least one second magnetic element magnetically attractable to the first magnetic element; and b) rotating the drive shaft; c) rotating the paintball feed mechanism via magnetic force between the at least one first magnetic element and at least one second magnetic element.
19. The method of claim 18 , wherein, the at least one first magnetic element and the at least one second magnetic element form a magnetic coupling between the drive shaft and the paintball feed mechanism.
20. The method of claim 18 , wherein the magnetic coupling causes the paintball feed mechanism to rotate in unison with the drive shaft.
21. The method of claim 18 , wherein the magnetic coupling disengages if the paintball feed mechanism is unable to rotate.
