Abstract

A desktop stapler uses a spring (90) 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 (90) with a nested lever (40). A multi function base (20) provides a sloped front all the way to down to a desk top surface to guide paper sheets atop the base, easy access for lifting the stapler off a desk, horizontal or vertical resting positions, and integrated soft grip under-surface. The base surrounds the rear of the stapler body (10) to provide a smooth exterior so that the device is natural to use both horizontally and vertically. A simple re-set spring (70) provides a smooth re-set action as the handle (30) is raised. A staple track includes enlargement features to fit a larger staple pusher spring (300).
