Abstract

A fastener driver comprises a housing and a magazine configured to retain a plurality of fasteners. A driver assembly is positioned within the housing and is configured to provide an expulsion force that expels one of the plurality of fasteners from the magazine. The device further includes a lockout member configured to pivot about a pivot axis between an unlocked position and a lockout position. The pivot axis is configured to move relative to the housing when a work contact element is depressed. The driver assembly is prevented from providing the expulsion force when the lockout arm is in the lockout position. The pivot arm moves from the unlocked position to the lockout position when a low level of fasteners remains in the magazine.

Description

technical field [0001] This invention relates to the field of power tools, and more particularly to devices for driving fasteners into workpieces. Background technique [0002] Fasteners, such as nails and staples, are commonly used in projects ranging from handicrafts to building construction. While manually driving the fasteners into the workpiece is feasible, the user can quickly become fatigued when the project involved requires a large number of fasteners and / or large fasteners. Furthermore, accurately driving larger fasteners into workpieces often requires more than one stroke from a hand tool. [0003] Based on the deficiencies of hand-driven tools, power-assisted devices for driving fasteners into workpieces have been developed. Contractors and homeowners commonly use such devices to drive fasteners ranging from brad nails for minor projects to common nail-driven fasteners for framing and other building work. Traditionally, compressed air has been used to power po...
