NOVELTY - The tool (10) has a motor positioned within a housing. A drive mechanism is supported by the housing and coupled to the motor. A battery pack is electrically coupled to the motor. A battery pack isolation system (70) includes an interface element (74) that is positioned within the housing. The interface element receives a portion of the battery pack to electrically couple the battery pack to the motor. Multiple annular-shaped isolators (78) are coupled between the housing and the interface element to isolate the battery pack from the housing during operation of the power tool.    USE - Multi-functional power tool for oscillating, rotating, reciprocating or driving an output element such as drill bit, cutting/scraping blade and sanding sheet, of an electrical device e.g. vacuum cleaner, outdoor power equipment such as blower, chain saw, edger, trimmer and lawn mower, and vehicle such as automobile, motorcycle, scooter and bicycle. Uses include but are not limited to a reciprocating saw, a drill, a circular saw, a jigsaw, a band saw, a screwdriver, an angle or straight grinder, a hammer drill and an impact spanner.    ADVANTAGE - The battery pack supplies power to the motor to energize the motor during operation of the power tool. The isolation system mechanically isolates the battery pack from the housing during operation of the power tool so as to reduce the magnitude of vibrations that are transferred to a battery pack and isolate the battery pack by the isolation system from vibrations caused by the motor and the drive mechanism. The tool reduces overall transfer of vibrations e.g. high frequency vibrations, to the battery pack during operation. The isolation system mechanically isolates the battery pack from the housing of the power tool at different frequencies or vibrations, such that vibrations from the motor and the drive mechanism are not transferred to the battery pack during operation of the power tool.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a battery pack isolation system for a power tool.
