Pusher mechanism for powered fastener driver

A powered fastener driver comprising:

• a housing;
• a nosepiece coupled to the housing and extending therefrom;
• a driver blade movable within the nosepiece between a ready position and a driven position;
• a canister magazine coupled to the nosepiece in which collated fasteners are receivable;
• a lifting mechanism operable to move the driver blade from the driven position toward the ready position;
• an electric motor operable to supply torque to the lifting mechanism to move the driver blade from the driven position toward the ready position;
• a pusher mechanism coupled to the nosepiece for individually transferring collated fasteners in the canister magazine to a driver channel in the nosepiece in which the driver blade is movable, the pusher mechanism including:
• a body coupled to the nosepiece for relative translation therewith,
• a feeder arm pivotably coupled to the body for movement therewith and engageable with a forwardmost fastener of the collated fasteners to transfer the forwardmost fastener into the driver channel, and
• a lever pivotably coupled to the nosepiece about a pivot axis, the lever having a first end engageable with the body for imparting reciprocating translation to the body relative to the nosepiece in response to pivoting movement of the lever in opposite directions about the pivot axis, and an opposite, second end;
• and
• a gear train operable to receive torque from the electric motor and distribute torque to the lifting mechanism, causing the pusher mechanism to be driven in sync with the lifting mechanism.

A powered fastener driver comprising:

• a housing;
• a storage chamber cylinder of pressurized gas positioned within the housing;
• a moveable piston positioned within the storage chamber cylinder;
• a nosepiece coupled to the housing and extending therefrom;
• a driver blade attached to the piston and movable within the nosepiece between a ready position and a driven position;
• a canister magazine coupled to the nosepiece in which collated fasteners are receivable;
• a lifting mechanism operable to move the driver blade from the driven position toward the ready position;
• an electric motor operable to supply torque to the lifting mechanism to move the driver blade from the driven position toward the ready position;
• and
• a pusher mechanism coupled to the nosepiece for individually transferring collated fasteners in the canister magazine to a driver channel in the nosepiece in which the driver blade is movable, the pusher mechanism including:
• a feeder arm coupled to the nosepiece for relative translation therewith along a first axis, and engageable with a forwardmost fastener of the collated fasteners to transfer the forwardmost fastener into the driver channel, and
• a solenoid having a solenoid housing and a plunger extending therefrom, the plunger being coupled to the feeder arm and movable along a second axis parallel to the first axis for imparting reciprocating translation to the feeder arm in response to activation and deactivation of the solenoid;
• wherein the lifting mechanism drives the piston and the driver blade to the ready position by energizing the electric motor.
