Paintball marker with convertible mechanical and electronic cartridges
View Patent ↗An apparatus for firing a projectile, such as a paintball, that comprises a trigger frame assembly that is detachable from either a mechanical cartridge or an electronic cartridge. The trigger frame assembly includes a trigger, a sear, and a frame on which the trigger and the sear are mounted. The trigger has a mechanical actuating surface and an electronic actuating surface. Both the mechanical cartridge and the electronic cartridge are configured to selectively attach to and detach from the frame. It is an aspect of the invention to allow a user to selectively and readily convert the apparatus between mechanical firing actuation and electronic firing actuation.
1. An apparatus for firing a projectile, the apparatus comprising:
a receiver for housing a firing assembly;
a trigger pivotally retained by the receiver, the trigger having a mechanical actuating surface and an electronic actuating surface; and
a cartridge removably and externally attached to the receiver, the cartridge comprising one of either a mechanical cartridge having a recess for permitting mechanical activation of the firing assembly or an electronic cartridge having a blocking surface for preventing mechanical activation of the firing assembly.
2. The apparatus of claim 1 , further comprising fasteners for selectively securing either the mechanical cartridge or the electronic cartridge to the receiver.
3. The apparatus of claim 1 , wherein a sear is pivotally retained by the receiver, the sear having a first trigger surface and second trigger surface, whereby the sear may be pivoted relative to the receiver by selectively engaging either the first trigger surface or the second trigger surface.
4. The apparatus of claim 3 , wherein when the mechanical cartridge is attached to the receiver, the recess allows the mechanical actuating surface to engage the first trigger surface.
5. The apparatus of claim 3 , wherein when the electronic cartridge is attached to the receiver, the blocking surface prevents the trigger from pivoting sufficiently for the mechanical actuating surface to engage the first trigger surface.
6. The apparatus of claim 1 , wherein the electronic cartridge has an electronic actuator, whereby when the electronic cartridge is attached to the receiver and the trigger is pivoted, the electronic actuating surface engages the electronic actuator.
7. The apparatus of claim 6 , wherein engaging the electronic actuator causes an armature pin to engage the second trigger surface.
8. The apparatus of claim 1 , wherein the electronic cartridge comprises a housing that forms a cavity at least partially accessible through a distal end of the housing for removably housing a power source.
9. The apparatus of claim 8 , wherein the cartridge further comprises a retainer attached to the distal end of the housing, the retainer being selectively adjustable between at least a first position and a second position, whereby when the retainer is in the first position, the retainer retains the power source in the housing, and when the retainer is in the second position, the retainer releases the power source allowing the power source to be removed from the housing.
10. The apparatus of claim 9 , wherein the cartridge further comprises:
an electronic actuator for initiating a trigger sequence;
a capacitor for storing a charge;
a solenoid; and
an armature pin for engaging a sear to fire the apparatus,
wherein
the housing retains the electronic actuator, the capacitor, the solenoid, and the armature pin when the cartridge is detached from the receiver.
