Patent ID: 7404507

Claim:
A spring actuated stapling device, comprising: a body; a track along a bottom of the body to guide staples toward a front of the stapling device; a handle pivotably attached to the body wherein the handle includes an initial position where the handle is pivoted to a farthest position away from the body and a pre-release position where the handle is pivoted toward the body; a striker movable vertically within the body between an initial high start rest position above the track and a lower-most position in front of the track, the striker rest position including the handle being in the initial handle position; a power spring disposed within the body and linked to the striker to bias the striker into the lower-most position; a lever pivotably attached to the body, wherein the lever links the handle to the power spring whereby pressing the handle causes the power spring via the lever to deflect and store energy; and a latch releasably engaging the striker to hold the striker in the initial rest striker position, the latch being pivotably engaged to the housing at a separate location from a pivotal attachment of the lever, wherein the lever moves the latch out of engagement at the pre-release position of the handle releasing the striker to accelerate to the lower-most position as the power spring moves to a lower position.
