Patent number: 7520061Abstract: A manually guided brushcutter or other trimmer having a guide tube that accommodates a transmission shaft, with a drive motor that drives the transmission shaft and a housing that secures the drive motor to the guide tube. The housing is embodied as a closed engine housing that surrounds the drive motor. The drive motor and the closed engine housing are interconnected at two spaced-apart securement points.Type: GrantFiled: April 10, 2006Date of Patent: April 21, 2009Assignee: Andreas Stihl AG & Co. KGInventors: Markus Herzog, Markus Hüsges, Thomas Sonnenkalb, Jürgen Steinmaier, Kai-Ulrich Machens

Publication number: 20080277132Abstract: A handheld work apparatus has an internal combustion engine (14, 44, 94) which has a crankshaft (15, 45, 95) which, in turn, drives a work tool of the work apparatus. The work apparatus has a first component group which includes the crankshaft (15, 45, 95) and which is driven in a first rotational direction (10, 40, 70, 90). In order to hold the gyroscopic forces low which act during operation, the work apparatus has a second component group which includes the work tool and which is driven in a second rotational direction (11, 41, 71, 91) opposite to the first rotational direction (10, 40, 70, 90).Type: ApplicationFiled: April 30, 2008Publication date: November 13, 2008Inventors: Lubomir Pesik, Johannes Menzel, Jurgen Steinmaier, Jurgen Erath

Publication number: 20070056575Abstract: A power tool device has a tool and a housing. An extension arm is provided that has a first end connected to the housing and a second end on which second end the tool is rotatably supported. A drive motor is arranged in the housing and rotatingly drives the tool. At least one mass body having a mass and being movably supported on a support is arranged in the area of the second end of the extension arm. The mass of the mass body or the support of the mass body or both are matched to vibrations occurring at the second end of the extension arm in operation of the power tool device so that the mass body at least partially compensates the vibrations occurring in operation of the power tool device.Type: ApplicationFiled: September 6, 2006Publication date: March 15, 2007Applicant: Andreas Stihl AG & Co.

Patent number: 6799373Abstract: A portable work apparatus, especially a motor-driven chain saw (1), has a drive unit which is provided with a handle housing (3). The handle housing (3) includes an extension (9) which extends in the longitudinal direction of the work apparatus from a rearward handle (8) on the side facing away in the longitudinal direction from a guide bar (6) forward to the side facing toward the guide bar (6). The handle housing (3) is connected via antivibration elements to the drive unit. The work apparatus has a forward handle tube (4), which extends over the work apparatus transversely to the longitudinal direction and is attached with an end (10) to the free end of the extension (9) and with the other end (27) in the area of the rearward handle (8). At least one of the ends (10, 27) of the handle tube (4) is fixed via an antivibration element (11, 25, 26, 28, 34).Type: GrantFiled: June 6, 2002Date of Patent: October 5, 2004Assignee: Andreas Stihl AG & Co.Inventors: Johannes Menzel, Markus Keller, Helmut Lux, Jürgen Steinmaier, Ralf-Rainer Kemmler

Patent number: 6550145Abstract: The invention is directed to a portable handheld work apparatus such as a brushcutter, edge cutter or the like. The work apparatus has a drive motor which drives a rotatable work tool via a drive shaft (3) journalled in a guide tube (2). The guide tube (2) is held in a housing (5) of the drive motor by an anti-vibration unit (6). The anti-vibration unit (6) includes a clamp (7) which surrounds the guide tube (2) and elastic damping elements (8, 9) which lie between the clamp (7) and the housing (5). The clamp (7) surrounds the guide tube (2) and is fixed form tight on the housing (5).Type: GrantFiled: July 13, 2001Date of Patent: April 22, 2003Assignee: Andreas Stihl AG & Co.Inventors: Gerhard Stoll, Andreas Schneider, Jürgen Steinmaier
