Abstract
A desktop stapler uses a spring to store energy to install staples by impact blow. The force required to fasten papers together is reduced. A very compact mechanism is used, including a dual coil power spring with a nested lever. A multi-function base provides a sloped front all the way down to a desktop surface to guide paper sheets atop the base, easy access for lifting the stapler off a desk while in its horizontal or vertical resting positions, and integrated soft grip under surface. The base surrounds the rear of the stapler body to provide a smooth exterior so that the device is natural to use both horizontally and vertically. A simple re-set spring provides a smooth re-set action as the handle is raised. A staple track includes enlargement features to fit a larger staple pusher spring.
Claims18
A desktop stapler, comprising:
- an elongated base;
- a body pivotably attached to the base toward a rear end of the stapler having a closed stapler position wherein the base and the body extend forward from the pivotal attachment in a parallel and spaced relationship between the base and the body;
- wherein the stapler includes a horizontal orientation where the base rests upon a desktop, and the base includes a front and a rear foot section, and a central portion of the base between the foot sections includes a top surface and an under surface;
- wherein the central portion includes a convex cross-sectional shape transverse to an extended length of the under surface, the top surface being substantially flat, and the top surface and the under surface meet along edges on each side of the central portion of the base, the edges each including a long straight segment extending in an elongated direction of the base, the under surface including a centrally aligned elongated lowest level of the central portion;
- and
- wherein the front and the rear foot sections extend below the lowest level of the under surface so that the central portion of the base is entirely raised above and spaced from a desktop surface upon which the stapler rests horizontally.
A desktop stapler to stapling sheet media together on a substantially flat work surface, comprising:
- an elongated base including a front foot section and a rear foot section having two downwardly extending corners to form a tripod support, and a central portion of the base between the foot sections including a top surface and an under surface with raised lateral portions;
- wherein the front foot section and rear foot section extend below the under surface of the central portion raising the central portion under surface above the work surface;
- wherein the front and the rear foot sections extend below the lowest level of the under surface so that the central portion of the base is raised above and spaced apart from the work surface upon which the stapler rests horizontally;
- a body pivotably attached to the base toward a rear end of the base;
- a handle pivotably disposed on the body;
- and
- means for storing and ejecting staples disposed within the body and actuated by the handle.
A desktop stapler to stapling sheet media together on a substantially flat work surface, comprising:
- an elongated base including a front foot section and a rear foot section having two downwardly extending corners to form a tripod support, and a central portion of the base between the foot sections including a substantially flat top surface and a convex under surface to form a D-shaped cross-section;
- wherein the front foot section and rear foot section extend below the under surface of the central portion raising the central portion under surface above the work surface;
- wherein the front and the rear foot sections extend below the lowest level of the under surface so that substantially the entire central portion of the base is raised above and spaced apart from the work surface when the stapler rests horizontally thereon;
- a body pivotably attached to the base toward a rear end of the base;
- a handle pivotably disposed on the body;
- and
- means for storing and ejecting staples disposed within the body and actuated by the handle.
A desktop stapler for stapling sheet media together on a substantially flat work surface, comprising:
- an elongated base including a front foot section and a rear foot section, an elongated continuous central portion of the base extending from the front foot section to the rear foot section including a substantially constant transverse cross-sectional shape of the central portion, with a flat top surface and a convex under surface of the central portion forming a D-shaped cross-section;
- wherein the front and the rear foot sections extend below a lowest level of the under surface of the central portion so that substantially the entire central portion of the base is raised above and spaced apart from the work surface when the stapler rests horizontally thereon;
- a body pivotably attached to the base toward a rear end of the base;
- a handle pivotably disposed on the body;
- and
- means for storing and ejecting staples disposed within the body and actuated by the handle.
