Abstract
A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and movable therewith between a top-dead-center (TDC) position and a driven or bottom-dead-center (BDC) position. The driver blade defines a driving axis. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween. A plurality of teeth extends from the first side of the body. A plurality of projections extends from the second side of the body. The body, the teeth, and the projections are bisected by a common plane. A lifter is operable to move the driver blade from the BDC position toward the TDC position, and is engageable with the teeth. A latch assembly is movable between a latched state, and a released state. The latch assembly is configured to engage with the projections.
