Powered fastener driver

A fastener driver comprising:

• a magazine configured to receive fasteners therein, the magazine including
• a magazine cover having a length extending along a longitudinal axis between a first end and a second end, and an opening defined proximate the second end, and
• a magazine body slidably movable relative to the magazine cover from a closed position to an open position for reloading the magazine with fasteners;
• a nosepiece including a fastener driving channel from which consecutive fasteners from the magazine are driven, the nosepiece adjacent the first end of the magazine cover;
• a latch coupled to the magazine cover and extending through the opening in the magazine cover, the latch including first and second latch projections that each define a first contact surface and that each extend through the opening in the magazine cover, the first contact surface defining a first plane oriented at an oblique angle relative to a vertical reference plane that is perpendicular to the longitudinal axis of the magazine;
• a pusher body slidably coupled to the magazine body, the pusher body including a pair of arm members that each define a second contact surface that is curvilinear;
• and
• a biasing member configured to bias the pusher body and the fasteners within the magazine toward the nosepiece when the magazine body is in the closed position,
• wherein the first and second contact surfaces are engageable to hold the pusher body in a latched position when the magazine body is in the open position.

• and
• a lock assembly configured to selectively couple the magazine body to the magazine cover to maintain the magazine body in the closed position, the lock assembly having a flange portion positioned within the magazine body,
• wherein the pusher body is automatically adjusted from the latched position to a released position by engagement between the flange portion of the lock assembly and the latch projection when the magazine body is moved toward the closed position,
• wherein the lock assembly is positioned at a rear end of the magazine body,
• wherein the latch includes first and second projections that each extend through the opening in the magazine cover,
• wherein each of the first and second projections includes a first contact surface engageable with a second contact surface on each of the pair of arm members on the pusher body when in the latched position, and
• wherein the first contact surface defines a first plane oriented at an oblique angle relative to a vertical reference plane that is perpendicular to the longitudinal axis of the magazine.
