Abstract: A safety mechanism to prevent unintended ejection of a staple or fastener in a stapler or fastening tool. A low-start version of the stapler has a handle that when pressed pivots a lever which lifts a striker and energizes a power spring. At the release point, the striker is released and accelerated under spring bias into a staple, ejecting the staple by impact blow. A high-start version has the striker stationary in the upper position as the power spring is energized. In the safety mechanism, a movable hook or arm selectively prevents the striker, and linked components thereto, from completing an operational cycle. In one embodiment the safety mechanism includes a working surface sensing button bar operating in conjunction with the hook that latches the striker. The safety mechanism can also be a pivoting lock bar that engages the working surface, which surface pivots the lock bar into engaging the power spring, handle, and/or striker thereby preventing such components from reaching the release point.

Abstract: A desktop stapler includes an automatic opening staple track whereby when the stapler is opened by pivoting the body about the base, the track is de-latched by ribs of the base, and the track slides out from a chamber within the body. The stapler includes a track alignment system that holds the front of the body precisely over the anvil by use of forward and rear torque arm contact areas between the base and track. The stapler also features a striker bottom edge that is shaped to follow the curved shape of the anvil so that the striker may enter the anvil recess without impacting the anvil. A staple chamber in the stapler has staple exit ribs that allow only one staple at a time to be ejected from the staple chamber.

Abstract: A spring actuated stapler includes a lever releasably linked to a striker at a lever front end. An elongated power spring is linked to the striker so that raising the lever front end deflects the power spring. The lever and power spring pivot about a common fulcrum structure. The fulcrum structure includes a rear facing surface and the lever pivots about the rear facing surface when the lever is near a lever release point. This pivot location is adjacent to the power spring, at a bottom of the structure of the fulcrum. With the lowest possible pivot location the lever retracts and releases from the striker more quickly than if the lever pivots about a higher location at a fulcrum “axial center”. The release action is therefore more consistent, and less sensitive to manufacturing variations of the stapler.

The stapler further includes a handle frame at an upper part of the operation frame pivotally attached to the support element such that a rear end part of the operation frame is located above the main shaft. An intermediate element is pivotally attached at one end to the handle frame. The other end of the intermediate element is pivotally attached to the operation frame.

Abstract: A stapler or like self-powered tool for dispensing and driving fasteners includes a safety mechanism to prevent unintended ejection of a staple or fastener. A movable hook normally obstructs the path of a staple so that the staple is intercepted and stopped as a spring-biased striker ejects the staple from the stapler. The striker preferably includes a notch and an end of the hook extends into the notch so that the safety mechanism can be compact. A button bar is linked to the hook and the button bar normally extends out from the stapler. When the stapler is placed against a working surface, the working surface presses the button bar vertically into the stapler, which causes the hook to rotate out from the striker slot and enables normal stapling operation.
