Device for cyclically operating a firearm trigger
View Patent ↗A device for cyclically operating a trigger of a firearm includes a glove having a finger stall, a pull mounted at the finger stall, and a drive mechanism coupled to the pull to move the finger stall from a bent configuration toward a straight configuration. The drive mechanism actuates in response to an activation signal.
1. A device comprising:
a base;
a spar extending forwardly from the base, the spar terminates at a pivot;
a rigid pull mounted at the pivot for pivotal movement, the pull configured to hold a finger;
a contact switch carried on the pull for detecting contact between the pull and an object; and
a drive mechanism operatively coupled to the pull to move the pull from a bent configuration of the finger toward a straight configuration of the finger;
wherein the drive mechanism actuates in response to an activation signal comprising the contact switch detecting the contact between the pull and an object.
2. The device of claim 1 , wherein the drive mechanism actuates cyclically in response to the activation signal.
3. The device of claim 1 , wherein the contact switch is a pressure switch.
4. The device of claim 1 , wherein:
the drive mechanism includes a pneumatic cylinder and a gas supply coupled in gaseous communication to the pneumatic cylinder; and
the pneumatic cylinder is coupled to the pull to move the pull toward the straight configuration of the finger.
5. The device of claim 1 , wherein:
the drive mechanism includes a solenoid and a battery coupled to the solenoid to provide power to the solenoid; and
the solenoid is coupled to the pull to move the pull toward the straight configuration of the finger.
6. The device of claim 1 , wherein:
the drive mechanism includes an eccentric mounted for rotational movement; and
the eccentric is coupled to the pull to move the pull toward the straight configuration of the finger.
7. The device of claim 6 , wherein:
the drive mechanism further includes a lever arm having a pivot end and a free end;
the free end of the lever arm is coupled to the pull; and
the eccentric is in contact with the lever between the pivot end and the free end to impart pivotal movement to the lever arm in response to rotational movement of the eccentric, so as to move the pull toward the straight configuration of the finger.
8. The device of claim 1 , wherein the pull includes a cradle configured to support a finger held by the pull.
9. The device of claim 8 , wherein the cradle includes a central hole formed therethrough providing a contact space for the finger held by the pull to contact a trigger.
10. The device of claim 1 , wherein the drive mechanism is carried on the base.
11. A device comprising:
a base and a spar extending forwardly from the base, the spar terminates at a pivot;
a rigid pull mounted at the pivot for pivotal movement, the pull configured to hold a finger;
biasing means for biasing the pull in a first direction, the biasing means comprising a drive mechanism carried on the base and operatively coupled to the pull to bias the pull between first and second positions along the first direction;
a switch coupled to the biasing means;
wherein in response to an activation of the switch, the biasing means cyclically actuates to cyclically bias the pull in the first direction.
12. The device of claim 11 , wherein the drive mechanism is configured with respect to the pull to bias the pull only along the first direction.
13. The device of claim 11 , wherein the drive mechanism is carried off the base.
14. The device of claim 11 , wherein the switch is a pressure switch.
15. The device of claim 11 , wherein the switch is carried on the pull.
16. The device of claim 11 , wherein the switch is disposed on an underside of the pull.
