Publication number: 20090114312Abstract: A router includes a motor housing containing a motor and coupled to a tool holder configured to receive a tool bit that is driven rotationally by the motor. A base receives the motor housing for movement in an axial direction along a longitudinal axis of the motor housing. A depth adjustment mechanism enables adjustment of a position of the motor housing relative to the base along the axial direction. The depth adjustment mechanism has a threaded shaft rotationally coupled to one of the motor housing and the base and a thread engaging member coupled to the other of the motor housing and the base. The threaded shaft is engageable with the thread engaging member. A seam defined in the base adjacent to the depth adjustment mechanism.Type: ApplicationFiled: December 17, 2007Publication date: May 7, 2009Applicant: Black & Decker Inc.Inventors: Randy G. Cooper, Mark A. Etter, Greg K. Griffin, Ginger L. Allen, Derrick Kilbourne

Patent number: 7524151Abstract: A power tool has a base assembly and a housing which is vertically movable relative to the base. The housing has a plurality of positioning components. A cutting depth adjustment mechanism is mounted on the base assembly and includes a support bracket and a sliding piece. The sliding piece is horizontally movable relative to the support bracket between a first position and a second position. When in the first position, the sliding piece is engaged with one of the positioning components and, when in the second position, the sliding piece is disengaged with the positioning components.Type: GrantFiled: January 8, 2008Date of Patent: April 28, 2009Assignee: Chervon LimitedInventor: Yongbing Zhu

Patent number: 7497649Abstract: A fixed base router has a base supporting an upright wall. A motor based driver assembly is received in a cylindrical interior space delimited by the wall and movable along a spiral path. A read-out system includes a position sensor that detects and applies the displacement of the driver assembly along the spiral path to a processor based circuit, which in turn generates a signal indicating the displacement and a display device showing up the displacement for visual inspection. The read-out system allows for precise positioning the driver assembly and thus setting a cutting depth of a tool bit carried on and driven by the driver assembly so that adjustment of positioning of the tool bit is made simple, readable and precise.Type: GrantFiled: January 25, 2007Date of Patent: March 3, 2009Assignee: Positec Power Tools (Suzhou) Co. Ltd.Inventor: Hongfeng Zhong

Patent number: 7490642Abstract: A router depth adjustment mechanism for minimizing rapid course depth adjustment for standard and plunge routers. Routers with rapid or course adjustment mechanisms may permit a router motor housing to drop suddenly, if the user is inattentive. Sudden adjustments may result in damage to the router and potentially contact the user. The mechanism of the present invention includes a threaded shaft and a biased thread engaging member which may be disengaged for rapid adjustment. A restraining device and/or a break may be included to minimize the rate of change.Type: GrantFiled: August 2, 2005Date of Patent: February 17, 2009Assignee: Black & Decker Inc.Inventors: Randy G.

Patent number: 7484915Abstract: A router includes a motor housing, a motor provided in the motor housing driving a collet for turning a cutting tool, and a base for resting on a workpiece. Support columns mounted to the base allow the motor housing to move relative to the base in a direction parallel to the rotational axis of the cutting tool. The support columns are spaced apart in a direction transverse to the rotational axis, and the motor housing is connected to the support columns by means of support members spaced apart in a direction parallel to the rotational axis.Type: GrantFiled: July 7, 2006Date of Patent: February 3, 2009Assignee: Black & Decker Inc.Inventor: Nigel Robson
