Device for storing projectile balls and feeding them into the projectile chamber of a gun
View Patent ↗The invention relates to a device for feeding ball-like ammunition, so-called paint balls, into the projectile chamber of a sporting arm. The magazine is arranged separately from the arm and is connected to same by means of a feeder tube. A motor-driven feeder feeds the balls from the ball container into the feeder tube. In so doing, a spring element stores the traction from the motor, so that, even when the motor stops, balls can still be transported using the energy stored in the spring element. The traction from the motor is transmitted via a connection or clutch consisting of a spring element and a transmission element. Protrusions are arranged on both the spring element and the transmission element, which come to bear on each other for transmitting traction. The protrusions are at least partially flexible, so that the transmitted force is limited. This way, explosion of the balls from excessive pressure is prevented. In addition, the feeder is connected with the drive element for the feeder, which is under pressure from the spring, by means of a bayonet-like connection. This way, the feeder can be removed from the ball container with one manipulation to facilitate the cleaning of the ball container in the event a ball explodes in spite of this.
1. Device for storing projectile balls and feeding them into the projectile chamber of a gun, having a ball container, a feeder tube connected to it with its one end, whose other end is connected with the gun, and a motor-driven feeder for feeding balls from the ball container into the feeder tube, a spring element transmitting the traction from the motor to the feeder and the spring element storing at least that traction energy which is necessary for feeding one ball into the projectile chamber, characterized in that the device comprises a slip clutch for transmitting the traction from the motor to the feeder.
2. Device according to claim 1 , characterized in that the slip clutch comprises a transmission element for traction having a plurality of protrusions, the protrusions being arranged at a distance from the axle of the transmission element and concentrically relative to said axle, in that the spring element has a protrusion for engaging the protrusions of the transmission element, and in that, in order to limit the torque transmittable from the transmission element to the spring element, the protrusions of the spring element and/or the transmission element are flexible.
3. Device according to claim 2 , characterized in that the feeder can be detachably connected with the transmission element by means of a bayonet connection.
4. Device according to claim 2 , characterized in that the feeder is a rotary feeder having its feeder chambers arranged at the periphery and having a conical elevation on its upper side.
5. Device according to claim 1 , characterized in that it disposes of freely rotating distance keeper mounted on the same axle as the transmission element, which maintains the protrusion of the spring element essentially at a set distance from the axle.
6. Device according to claim 5 , characterized in that the system for intermittently switching on is dependent on the movement of the balls in the feeder tube.
7. Device according to claim 5 , characterized in that the feeder can be detachably connected with the transmission element by means of a bayonet connection.
8. Device according to claim 5 , characterized in that the feeder is a rotary feeder having its feeder chambers arranged at the periphery and having a conical elevation on its upper side.
9. Device according to claim 1 , characterized in that it comprises a flexible element above the feeder adjacent to the feeder tube, the flexible element being fixed to the ball container with its one end.
10. Device according to claim 9 , characterized in that it comprises a sensor for detecting the movement of the balls in the feeder tube and that the sensor is arranged on the end of the feeder tube that is close to the hand gun.
11. Device according to claim 9 , characterized in that the feeder can be detachably connected with the transmission element by means of a bayonet connection.
12. Device according to claim 9 , characterized in that the feeder is a rotary feeder having its feeder chambers arranged at the periphery and having a conical elevation on its upper side.
13. Device according to claim 1 , characterized in that there is a system for intermittently switching on the motor.
14. Device according to claim 13 , characterized in that the feeder can be detachably connected with the transmission element by means of a bayonet connection.
15. Device according to claim 13 , characterized in that the feeder is a rotary feeder having its feeder chambers arranged at the periphery and having a conical elevation on its upper side.
16. Device according to claim 1 , characterized in that the feeder can be detachably connected with the transmission element by means of a bayonet connection.
17. Device according to claim 1 , characterized in that the feeder is a rotary feeder having its feeder chambers arranged at the periphery and having a conical elevation on its upper side.
18. Device for storing balls and feeding them into the projectile chamber of a gun, having a ball container, a feeder tube connected to it with its one end, whose other end is connected with the gun and a motor-driven feeder for feeding balls from a ball container into the feeder tube, a spring element transmitting the traction from the motor to the feeder and the spring element storing at least that traction energy which is necessary for feeding one ball into the projectile chamber, characterized in that the feeder disposes of a bayonet connection with a transmission element for the feeder, which is under pressure from the spring.
19. Device according to claim 18 , characterized in that the feeder is a rotary feeder having its feeder chambers arranged at the periphery and having a conical elevation on its upper side.
