A percussion tool including a parking assembly movable relative to a spindle. The parking assembly includes a seat coupled to the spindle, a first shuttle portion movable relative to an outer surface of the spindle, a biasing member positioned between the seat and the first shuttle portion, a second shuttle portion movable relative to the outer surface of the spindle, a bushing positioned within the spindle and configured to receive a portion of an anvil, and a fastener that couples the second shuttle portion to the bushing. The first shuttle portion and the second shuttle portion are movable together between a working position, in which a plurality of radial air vents in the spindle is closed, and an idle position, in which the plurality of radial air vents is open. The biasing member is configured to bias the first shuttle portion and the second shuttle portion into the idle position.

Percussion tool

A rotary hammer includes a housing and a mode selection dial supported in the housing. The mode selection dial includes a cam. The housing supports a motor providing a rotational output. The housing supports a linkage moveable between a first position and a second position in response to engagement by the cam. A loss-of-control detection system measures acceleration of the housing and disables the motor upon the acceleration exceeding an acceleration threshold. The housing supports an operating mode detection system including a magnet and a Hall-effect sensor. The magnet is coupled to the linkage and moveable therewith between a third position corresponding to the first position of the linkage and a fourth position corresponding to the second position of the linkage. The Hall-effect sensor provides an output signal indictive of the position of the magnet. The loss-of-control detection system is selectively disabled based upon the output signal.

Operating mode detection system for rotary hammer

A handheld power tool including a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, and a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory. A dust container is selectively coupled to the housing. A dust tube is coupled to the first end of the housing and in fluid communication with the dust container, wherein the dust tube is movable between an extended position and a retracted position. A fan is positioned within the housing and is operable to generate a suction air flow path through the dust tube and into the dust container, wherein the fan rotatably driven by the motor.

Integrated dust extractor and power tool

The present invention provides, in one aspect, a router including a motor unit and a base configured to selectively receive the motor unit to support the router on a work piece surface. The motor unit includes a motor and a spindle configured to output a torque supplied by the motor. The base includes an input shaft configured to selectively couple to the spindle, an output shaft laterally offset from the input shaft, and a belt. The input shaft includes a first pulley and the output shaft includes a second pulley and a tool holder. The belt wraps around the first and second pulleys to rotationally couple the input shaft to the output shaft. When the motor unit is received into the base, the spindle couples to the input shaft.

Offset base for router

A handheld power tool includes a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory, and a dust collection assembly integrated within the housing. The dust collection assembly includes a fan disposed within the housing and operatively coupled to the motor. The fan is configured to generate a suction airflow due to rotation of the motor, and a dust container removably coupled to the housing of the power tool. The dust container is configured to collect dust and other debris generated by the tool accessory during operation of the handheld power tool.

A rotary hammer includes a motor and a spindle coupled to the motor for receiving torque from the motor. The spindle has an adjustable rotation speed. A reciprocation mechanism is operable to create a variable pressure air spring within the spindle and includes a piston configured to reciprocate within the spindle in response to receiving torque from the motor. The piston has an adjustable reciprocation frequency. A striker is selectively reciprocable within the spindle in response to reciprocation of the piston. A first transmission is transfers torque from the motor to the spindle and a second transmission is transfers torque from the motor to the reciprocation mechanism. The reciprocation frequency of the piston is adjustable independent of the rotation speed of the spindle. The rotation speed of the spindle is adjustable independent of the reciprocation frequency of the piston. At least one of the transmissions is a multi-speed transmission.

Rotary power tool

A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.
