High-start spring energized stapler

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 position above the track and a lower-most position in front of the track;
• a power spring disposed within the body linked to the striker, wherein the power spring is deflected and energized as the handle moves from the farthest position to the pre-release position;
• and
• a cage at least partially confining the power spring wherein the power spring is preloaded in a rest position, and wherein the cage is separately movable from the handle.

A spring actuated stapling device, comprising:

• 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 substantially vertically within the body between an initial rest position above the track and a lower most position in front of the track;
• a power spring disposed within the body linked to the striker;
• a latch movably attached to the body in front of the striker, the latch extending to a location of engagement with the striker, the latch releasably engaging the striker to hold the striker in the initial striker position;
• wherein at the pre-release position of the handle, the latch disengages from the striker, and the striker accelerates to the lower-most position under bias of the power spring as the power spring moves to a lower position.

• a striker movable vertically within the body between an initial position above the track and a lower most position in front of the track;
• a power spring disposed within the body and linked to the striker, the power spring being pivotably attached to the body at a rear power spring mount, wherein the power spring is deflected and energized as the handle moves from the farthest position to the pre-release position;
• and
• a reset spring biasing a power spring front end upward toward an initial position of the power spring, the reset spring being an extension of a same material of the power spring and is cantilevered forward from a base at a rear of the power spring.

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, the handle including a handle fulcrum extending underneath at about a center portion of the handle, and a release cam extending from underneath a front end thereof;
• a striker movable vertically within the body between an initial position above the track and a lower-most position in front of the track;
• a power spring disposed within the body linked to the striker at a front end thereof to bias the striker to the lower-most position, wherein the handle pivots on the handle fulcrum, which deflects the power spring as the handle moves from the farthest position to the pre-release position;
• a pivoting release latch supported by the body and biased toward engagement with the power spring;
• a cage fulcrum disposed against the body interior;
• a cage disposed on the cage fulcrum at the back end thereof and at least partially confining the power spring via a tab extending from underneath the power spring to press down on the power spring to preloaded the power spring in a rest position;
• and
• wherein when the handle is moved to the pre-release position, the cam forces the latch to pivot away and disengage from the power spring thereby freeing the power spring to bias the striker into the lower-most position.

• wherein the latch includes an unstable engagement with the striker and a cam providing a link between the handle and the latch, the cam selectively holding the latch engaged to the striker;
• and
• wherein at the pre-release position of the handle, the latch disengages from the striker, and the striker accelerates to the lowermost position under bias of the power spring as the power spring moves to a lower position.
