Patent number: 9475182Abstract: A hand-held power tool includes a tool housing and a handle housing. The handle housing is movable relative to the tool housing. The hand-held power tool also includes an electric motor for driving the hand-held power tool. The electric motor is switched on and off by a relative movement of the handle housing relative to the tool housing. The hand-held power tool also includes a main electrical switch configured to apply an electrical voltage supply to the electric motor. The main electrical switch is switched by an actuating mechanism. The main electrical switch is actuatable with the aid of a movable component that is movable relative to the tool housing handily via the actuating mechanism, either directly or by the actuating mechanism.Type: GrantFiled: October 10, 2012Date of Patent: October 25, 2016Assignee: Robert Bosch GmbHInventors: Andre Ullrich, Holger Ruebsaamen

Publication number: 20130284476Abstract: A hand power tool includes at least one drive unit, at least one housing, and at least one switchover element. The at least one drive unit is configured to drive an insert tool. The at least one housing at least partially encloses the drive unit. The at least one switchover element is configured to switch over a drive direction of the at least one drive unit. The at least one switchover element includes at least one actuating face that has at least two switching positions. The at least one actuating face is at least partially configured such that, when in the at least two switching positions, the at least one actuating face is at least substantially flush with the at least one housing.Type: ApplicationFiled: April 23, 2013Publication date: October 31, 2013Applicant: Robert Bosch GmbHInventors: Andre Ullrich, Holger Ruebsaamen

Publication number: 20120279741Abstract: An electric tool includes a vibratory means which is configured to impart a counteracting vibration which counteracts a housing vibration of the electric tool. A vibration-relevant characteristic of the vibratory means can be adapted during the operation of the electric tool in such a way that the amplitude, the phase position and/or the frequency of the counteracting vibration varies with a change in the vibration-relevant characteristic. The vibratory means of the electric tool has a natural frequency which can be varied by variation means of the electric tool. A method for compensating housing vibrations, in particular of the electric tool, includes imparting a counteracting vibration by a vibratory means which counteracts a housing vibration of the electric tool. The amplitude, the phase position and/or the frequency of the counteracting vibration is varied during the operation of the electric tool.Type: ApplicationFiled: October 6, 2010Publication date: November 8, 2012Applicant: ROBERT BOSCH GMBHInventors: Gerd Schlesak, Carsten Diem, Willy Braun, Hardy Schmid, Holger Ruebsaamen, Michael Weiss, Jan Koalick, Peter Loehnert

Patent number: 8245791Abstract: The invention relates to a hand-held tool, in particular a rotary hammer, a percussion hammer, or a sabre saw. The hand-held tool is equipped with a drive unit and a stroke-generating element; the drive unit is embodied to move the stroke-generating element in a reciprocating fashion along a translation axis. The hand-held tool has at least one counterweight; the counterweight is operatively connected to the drive unit in such a way that it is possible to at least partially compensate for forces at least indirectly caused by the reciprocating motion. According to the invention, the counterweight in the hand-held tool is supported so that it is able to move, in particular to reciprocate, coaxial or parallel to the translation axis.Type: GrantFiled: March 16, 2010Date of Patent: August 21, 2012Assignee: Robert Bosch GmbHInventors: Joerg Kriedel, Richard Engel, Otto Baumann, Hardy Schmid, Holger Ruebsaamen, Mario Patzig
