Patent number: 10525578Abstract: A power tool includes a tool handle and a tool head. The tool handle includes a housing having a grip portion and defining a longitudinal axis, a motor disposed within the housing and including a drive shaft having an axis of rotation substantially parallel to the longitudinal axis, a trigger positioned adjacent the grip portion for selectively activating the motor, and a handle interface. The tool head is selectively coupleable to the tool handle and includes a head interface for coupling with the handle interface of the tool handle, a transmission driven by the drive shaft of the motor when the tool head is coupled to the tool handle, and an output member coupled to the transmission. The output member defines an axis generally perpendicular to the axis of rotation of the drive shaft.Type: GrantFiled: March 27, 2018Date of Patent: January 7, 2020Assignee: TECHTRONIC POWER TOOLS TECHNOLOGY LIMITEDInventors: Siu Yan Lau, Jason P. Whitmire, Jason Brandenburg, Thomas Parel, Taku Ohi

Patent number: 9931743Abstract: A power tool having a removable head, a motor, a trigger, and a trigger stop movable between first and second positions. In the second position the trigger is unlocked to permit activation of the motor. A linkage is coupled to the trigger stop and is positioned at a first radial distance from the first central axis. A plurality of actuators extend from the head and are positioned at a second radial distance substantially equal to the first radial distance. When the head is coupled to the handle in a first rotational orientation, one of the plurality of actuators engages the linkage to move the trigger stop to the second position, and when the head is coupled to the handle in a second rotational orientation different from the first rotational orientation, another one of the plurality of actuators engages the linkage to move the trigger stop to the second position.Type: GrantFiled: July 7, 2015Date of Patent: April 3, 2018Assignee: TECHTRONIC POWER TOOLS TECHNOLOGY LIMITEDInventors: Siu Yan Lau, Jason P.

Publication number: 20160135269Abstract: A wireless power distribution system and method for power tools and other battery-powered devices. The system includes a power transmitter configured to transmit a power signal within a first power distribution volume and a plurality receivers configured to receive the power signal. The receivers include power harvesters, batteries, light sources and light sensors. The receivers determine whether the received power signal is greater than a power threshold value and convert the RF power signals into direct current. The direct current is used to charge a battery, power the light source, etc. The light source selectively receives power from the battery when the ambient light, detected by the light sensor, is below a light threshold value.Type: ApplicationFiled: January 15, 2016Publication date: May 12, 2016Inventors: Mike Hornick, Robert E. McCracken, Mark Huggins, Jason P. Whitmire

Patent number: 9257865Abstract: A wireless power distribution system and method for power tools and other battery-powered devices. The system includes a power transmitter and a plurality of power harvesters or receivers. The receivers are located in power tools, battery packs that are attachable to and detachable from the power tools, a device or case that is interfaceable with the power tool or battery pack, conventionally-sized batteries, or other battery-powered devices. The power transmitter transmits radio frequency (“RF”) power signals to the receivers that are within transmission range of the power transmitter. The receivers receive the RF power signals and convert the RF power signals into direct current. The direct current is used to charge a battery, directly power a tool, etc.Type: GrantFiled: March 22, 2012Date of Patent: February 9, 2016Assignee: Techtronic Power Tools Technology LimitedInventors: Mark Huggins, Robert E.

Patent number: 9085077Abstract: A power tool head is removably connectable to a power tool handle. The power tool head has an output for performing an operation on a work piece, and a housing having an inner surface defining a main cavity for receiving an interface of the power tool handle. The housing has an outer surface generally opposite the inner surface. The power tool head also has a first opening for selectively receiving a drive shaft for transferring rotation of the drive shaft to the output, the opening defining a central axis. The power tool head also has a pin extending substantially parallel to the central axis for depressing a trigger lock button, and a second opening extending from the inner surface to the outer surface in a direction generally radial with respect to the central axis for receiving a release member.Type: GrantFiled: February 25, 2014Date of Patent: July 21, 2015Assignee: Techtronic Power Tools Technology LimitedInventors: Siu Yan Lau, Jason P. Whitmire, Jason Brandenburg, Thomas Parel, Taku Ohi

Patent number: 8122971Abstract: An impact rotary tool is provided that is switchable between an impact mode where the tool delivers an impacting torque on an output tool and a drill mode where the driver delivers a smooth output on an output tool. The impact rotary tool includes an impact mechanism and a hammer block that in the impact mode is movable parallel to the axis of the driver shaft and delivers reciprocating blows to rotate an anvil and in the drill mode substantially constantly engages the anvil. The impact mechanism includes a stopper that does not contact the hammer block in the impact mode and engages the hammer block in the drill mode to maintain the substantially constant contact between the hammer block and the anvil.Type: GrantFiled: September 23, 2010Date of Patent: February 28, 2012Assignee: Techtronic Power Tools Technology LimitedInventors: Jason P.
