Publication number: 20140000921Abstract: A power tool includes a housing, an output shaft having a tool axis, and a motion sensor that senses motion of the tool housing. A control circuit receives an input signal from the motion sensor, to make a first determination, based on the input signal, whether the tool is being operated in a horizontal mode or a vertical mode. The control circuit makes a second determination, based on the input signal, whether the tool axis is substantially level when the tool is being operated in the horizontal mode or the tool axis is substantially plumb when the tool is being operated in the vertical mode. An indicator receives an output signal from the control circuit that causes the indicator to indicate whether the tool axis is level when being operated in the horizontal mode or plumb when being operated in the vertical mode.Type: ApplicationFiled: February 28, 2013Publication date: January 2, 2014Applicant: BLACK & DECKER INC.Inventors: John C.

Publication number: 20130306699Abstract: A driving tool with a housing, a motor received in the housing, a control unit and a trigger. The housing defines a handle. The control unit is configured to operate the motor and has a microswitch, an actuator arm and a spring. The actuator arm is biased by the spring toward the microswitch. The spring is configured to move the actuator arm against the microswitch to cause the microswitch to operate in an actuated switch state. The trigger is coupled to the handle and is movable between a first trigger position and a second trigger position. The trigger has a switch arm that cooperates with the actuator arm to form a lost-motion coupling that permits a predetermined amount of movement of the trigger from the first trigger position to the second trigger position before coupling the switch arm to the actuator arm. The actuator member does not contact the microswitch when the trigger is in the second trigger position so that the microswitch operates in a nominal switch state.Type: ApplicationFiled: July 23, 2013Publication date: November 21, 2013Applicant: Black & Decker Inc.Inventors: Ashok S.

Publication number: 20130284471Abstract: A power tool includes a housing, an output member that rotates about a longitudinal axis, and a motor drivably connected to the output member. A rotational motion sensor is arranged in the housing and operable to detect a user input that includes a rotational motion of the housing in a desired rotational direction about the longitudinal axis of the output member. A controller is configured to receive a first input indicative of a user-desired rotational motion of the output member, and a second input, from the rotational motion sensor, indicative of an actual rotational motion of the power tool. The controller determines a user-desired rotational direction of the output member about the axis from the first input, determines an actual rotational direction of the housing about the axis from the second input, and causes the motor to drive the output member to simulate ratcheting movement in the user-desired rotational direction.Type: ApplicationFiled: January 31, 2013Publication date: October 31, 2013Inventors: Scott J. Eshleman, Craig A. Schell, Andrew E. Seman, JR., Daniel Puzio, Daniele C. Brotto, Joseph P. Kelleher, Sankarshan Murthy

Patent number: 8418778Abstract: An improved method is provided for operating a power tool. The method includes: monitoring rotational motion of the power tool about an axis using a rotational motion sensor disposed in the power tool; determining a direction of the rotational motion about the axis; and driving the output member in a direction defined by the detected rotational motion of the tool, where the output member is driven by a motor residing in the power tool. Thus, the output member is drive clockwise when the rotational motion of the tool is clockwise about the axis and the output member is drive counter-clockwise when the rotational motion of the tool is counter-clockwise about the axis.Type: GrantFiled: February 24, 2012Date of Patent: April 16, 2013Assignee: Black & Decker Inc.Inventors: Scott Eshleman, Craig Schell, Andrew E.

Patent number: RE44311Abstract: A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.Type: GrantFiled: March 19, 2012Date of Patent: June 25, 2013Assignee: Black & Decker Inc.Inventors: Qiang Zhang, Uday Deshpande, John Charles Vanko, Jason Leh, Craig Schell, Thomas Jay Bodine, Joao Norona, David Beers
