Abstract: An oscillating power tool includes a housing and a motor at least partially disposed within the housing and having a rotational output shaft. An eccentric bearing is attached to the output shaft. An oscillating member is coupled to the eccentric bearing to convert rotational movement of the eccentric bearing into oscillating movement. A pivot shaft has an oscillating axis and the oscillating member is arranged on it. A tool engagement area is disposed on the oscillating member for engaging a detachable tool. The tool engagement area substantially surrounds the oscillating axis and has protruding tool connecting members extending parallel to the oscillating axis for axial mounting of the detachable tool to the tool engagement area.

Abstract: A bearing support assembly for supporting a bearing of an electric motor output shaft relative to a housing. The bearing assembly includes a rigid cap that receives the bearing and resilient boot disposed in the cap between the bearing and cap inner surface. The cap has an irregularly shaped outer surface that interfaces with housing structures to permit the small motions over five degrees of freedom. The bearing support assembly permits self-alignment of the bearing with respect to the motor output shaft and also permits adjustment of natural frequencies of the system that includes the motor, the bearing and the housing. As a result, an improved response to mass unbalances and external loads is achieved.

Abstract: A hand-held rotary power tool includes a housing that provides a manual grip zone that is grasped by the user during operation of the tool. The housing includes a switch opening that overlies an electrical switch that controls operation of a tool motor. The tool includes a switch actuator that is disposed in tool housing so as to be accessible to a user of the tool via the switch opening and is operable to control the position of the switch. The switch actuator is configured to damp tool noise and transmission of tool vibration to the tool housing.

Abstract: A power tool includes a motor and a power supply that are connected by a switch disposed in an electrical circuit. The switch controls the on/off state of the motor and is actuated by a switch actuator that serves as a spring element. The switch actuator includes a guide plate supported on the housing, and a resilient arm that protrudes from the guide plate into an opening in the tool housing. When the switch actuator is in a first actuator position relative to the housing, the resilient arm is biased toward an edge of the opening and engages the edge, thereby preventing inadvertent movement of the switch actuator to the second actuator position. When the switch actuator is actuated by applying a bi-directional manual force to the resilient arm, the resilient arm is displaced from the edge, thereby permitting movement of the switch actuator to the second actuator position.

Abstract: An oscillating power tool includes a drive motor (M) producing rotary motion and an oscillating mechanism (30) for converting the motor rotary motion to an oscillatory side-to-side movement. The oscillating mechanism (30) includes a link (32) driven by an eccentric shaft (16) of the motor (M), a drive arm (40) that drives the hub (45) of the working tool (B) in oscillating motion, and a bearing arrangement (37) between the drive arm (40) and the link (32) that isolates relative rotation and translation between the components while still imparting an oscillatory motion to the drive arm (40).
