Abstract: A power tool assembly includes a power tool having a battery support portion that defines a battery insertion axis and a battery operatively engageable with the power tool support portion along the battery insertion axis to provide power to the power tool. The power tool assembly also includes a battery latching mechanism having a latch pivotable about a pivot axis transverse to the battery insertion axis and engageable with one of the battery pack or the battery support portion for securing the battery pack to the battery support portion. The battery latching mechanism further includes a handle coupled for pivoting movement with the latch about the pivot axis.

Abstract: A direct current fastening device and related control methods. The fastening device is powered by a direct current power source and includes a variety of safety and control features that allow the fastening device to be safety operated without, for example, a mechanical safety linkage or assembly between a trigger and a fastener firing portion (e.g., a nose switch) that prohibits the operation of the fastening device. Rather, the fastening device described herein employs a controller, a variety of switches, and monitoring techniques to ensure the safe and reliable operation of the fastening device. The configuration of the controller, for example, replaces the mechanical linkages and assemblies between the trigger and the fastener firing portion (e.g., a nose switch) that are ubiquitous safety features for such fastening devices.
