US 7,407,072 B2 · Contoured base for desktop stapler

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.
