Abstract

A device for cyclically operating a trigger of a firearm includes biasing means for biasing a finger applied to a trigger away from the trigger, and a contact switch coupled to the biasing means and configured to be disposed between the finger and the trigger. In response to the contact switch detecting contact between the finger and the trigger, the biasing means actuates to cyclically bias the finger away from the trigger.

Claims

1. A device comprising:

a glove having a finger stall and a contact switch carried on the glove for detecting contact between the glove and an object;

a pull mounted at the finger stall; and

a drive mechanism operatively coupled to the pull to move the finger stall from a bent configuration toward a straight configuration;

wherein the drive mechanism actuates in response to an activation signal, and the activation signal comprises the contact switch detecting the contact between the glove and the 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 finger stall toward the straight configuration.

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 finger stall toward the straight configuration.

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 finger stall toward the straight configuration.

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 and free ends to impart pivotal movement to the lever arm in response to rotational movement of the eccentric, so as to move the finger stall toward the straight configuration.

8. The device of claim 1, wherein the pull includes a cradle configured to support a finger fit through the finger stall.

9. The device of claim 8, wherein the cradle includes a central hole formed therethrough providing a contact space for the finger fit through the finger stall to contact a trigger.

10. The device of claim 1, wherein the drive mechanism is carried on the glove.
