Patent number: 11097442Abstract: A portable power tool, in particular a hand-held planing machine, includes at least one workpiece contact unit and at least one handle unit. The workpiece contact unit has at least one workpiece contact surface, and the handle unit has at least one main handle. The main handle has at least one maximum distance point that, in a direction extending at least substantially perpendicularly to a workpiece contact surface, has a maximum distance from the at least one workpiece contact surface. The maximum distance is less than 150 mm.Type: GrantFiled: July 12, 2019Date of Patent: August 24, 2021Assignee: Robert Bosch GmbHInventors: Tom Staeubli, Robert Simm, Thomas Bannwart, Nico Spinelli

Patent number: 8360120Abstract: A two-sided planer comprises a base, an adjusting base, and a floated pressing unit. Wherein, the floated pressing unit includes an axle shaft superimposed by several pressing rings. A spacing is defined between an inner surface of the pressing ring and the axle shaft. Plural elastic propping element are disposed within the spacing. Thereby, in the planing operation, the pressing rings adjust their positions upward or downward in accordance with a configuration of a workpiece. Whereby, the workpiece is restricted rather than warped. As a result, the workpiece does not resume warped after being planed smooth, which allows the two-sided planer to achieve a preferable planing operation.Type: GrantFiled: August 18, 2010Date of Patent: January 29, 2013Inventor: Bor-Yann Chuang

Patent number: 8020592Abstract: The invention provides a power tool planer which includes a drum with at least one blade thereon located within a chamber in the tool housing. One end of the chamber is provided with an opening which can be selectively closed by a guard. The guard can be moveable between a first closed position and a second position in which the chamber is opened, and the guard is moved into a recess in the housing to improve the ability to use the tool in confined spaces, as the guard lies flush with a side wall of the housing. Also provided is a dust and debris extraction system and a means for adjusting the depth of cut obtained using the tool.Type: GrantFiled: May 23, 2008Date of Patent: September 20, 2011Assignee: Power Box AGInventor: Marcus Nicolson

Publication number: 20090293991Abstract: A hand held electrically powered planer including a housing; an electric motor mounted within the housing; a work piece engaging shoe mounted on the underside of the housing having an aperture formed therethrough; and a cutting drum rotatably mounted within the housing, which is capable of being rotatably driven by the electric motor when the electric motor is activated. A part of the cutting drum protrudes through the aperture to engage a work piece. A cutting blade is mounted on the cutting drum. A rear handle is mounted on the housing and includes an elongate shaft attached at one end only to the rear of the housing and extends forward in a lengthwise direction over a portion of the housing toward the front end of the housing. A grip is mounted or formed on the elongate shaft and there is a front handle which is mounted on the free end of the shaft forward of the grip.Type: ApplicationFiled: May 27, 2009Publication date: December 3, 2009Applicant: Black & Decker Inc.Inventors: Isabell Rosenau, Ian Bell

Publication number: 20090000696Abstract: A planer (102) has a housing (104) with a shoe (138) and an aperture (136) in the shoe The planer includes a motor (112) mounted adjacent to the aperture in the shoe, a stator non-rotatably mounted to the housing, and a rotor arranged substantially coaxially around the stator and adapted to rotate relative to said stator. The planer also includes a battery that is located above the shoe. A pair of blades (132) are mounted for rotation with the rotor and protrude through the aperture to engage and to remove surface material from a workpiece.Type: ApplicationFiled: June 20, 2008Publication date: January 1, 2009Applicant: BLACK & DECKER INC.Inventors: Horst Grossman, Stefan Sell

Patent number: 7124793Abstract: An apparatus for a portable planer 12 having rails 14 with means for mounting to a single use stand 16, 18. The planer 12 has a pair of rails 14 with bolts 48 depending from the base thereof having threads with nuts 50 positioned on the distal ends whereby a stand 16, 18 having been constructed on site and leveled regardless of ground slope has means for receiving the threaded bolts 48 whereupon fasteners may be placed on the rail post distal ends whereby the rails form an integral part of the single use stand. The motorized planer 12 is mounted to a carriage 40 having wheels 42 for mounting on the rails 14 whereby the planer can be selectively moved from one rail end to the other. Positioned between the single use rail mounts are supports 26 for placing the work piece thereon for processing with the planer having means for receiving various blades 56, 58 and means for varying 62, 64 the height of the blade relative to the work piece.Type: GrantFiled: February 23, 2004Date of Patent: October 24, 2006Inventor: Robert L Jensen

Patent number: 6612089Abstract: An electric inside corner planer (20) with a cylindrical cutter assembly (30) has a housing (21) and front shoe (22) constructed with a side angled along a line (46) determined by the front outside of the cutter (30) and the front outside of the bearing (41) holding the cutter. The angled side of the planer puts the cutter assembly as close as possible to the interfering structure in the corner. Right angled (20), left angled (70), and combined right and left angled (120) planer embodiments are shown.Type: GrantFiled: December 21, 2001Date of Patent: September 2, 2003Inventor: Christopher L. Mann

Patent number: 6347652Abstract: A machine for planing large wood timbers or other heavy wood products easily by self-propelling along the work piece and planing the wood surface as it goes. The machine has a set of planer knives driven by a power source, a set of rollers before and after the knives for self feeding the planer down the work, and a flat surface in front and behind the rollers and cutting knives for stability and smoothness. The roller may also be adjusted in relation to the cutters for depth of cut and/or slightly angling the cut to one side. Centering guides keep the unit balanced on the work piece. There can be multiple feed rollers in front and behind the planer knives.Type: GrantFiled: July 18, 2000Date of Patent: February 19, 2002Inventor: Scott A Hunter
