Abstract
An oscillating power tool includes a tool mount which can be articulated through a range of positions including less than zero degrees to ninety degrees. The tool mount can accept a variety of accessory tools which move in a reversing angular displacement as well as articulate throughout the range of positions. A locking mechanism is provided that can be manually actuated to prevent articulation or rotation of the articulator to thereby fix the tool mount to a pre-selected orientation.
Claims15
An articulating power tool comprising:
- a housing;
- a motor located in the housing, the motor including a drive shaft configured for rotation about a first axis;
- an actuator operatively coupled to the drive shaft configured to convert the rotation of the drive shaft to a reversing angular displacement;
- a tool holder coupled to the actuator and configured to move in response to movement of the actuator;
- an articulator operatively coupled to the housing and to the tool holder, the articulator configured to adjust the tool holder through a range of angular positions relative to the housing;
- and
- a locking mechanism operatively coupled between the articulator and the housing for locking the articulator in a user-selected one of said range of angular positions,
- wherein the articulator includes a barrel element with a clamping surface facing the locking mechanism;
- and
- wherein the locking mechanism is provided with a mating clamping surface, the clamping surfaces configured to prevent relative rotation when the surfaces are pressed together.
