20110139477 | HANDHELD POWER TOOL - The invention is based on a handheld power tool, having at least one vibration-cancelling device that has at least one cancellation spring and one cancellation mass. It is proposed that the cancellation mass is constructed of at least one first mass part and at least one second mass part. | 06-16-2011 |
20120227995 | Connecting Rod Drive Comprising an Additional Oscillator - An electric tool includes a striking mechanism assembly, which can be driven in and against a striking direction in a cyclic manner, and a counter-oscillator for compensating for vibrations of the electric tool, in particular of housing oscillations, comprising a balancing mass. The balancing mass can be driven in a movement direction by driving the striking mechanism assembly, wherein the movement direction extends at an angle to the striking direction. | 09-13-2012 |
20120255753 | HAND-POWER TOOL WITH AN OSCILLATION-DAMPING DEVICE - A hand-power tool includes at least one oscillation-damping device that has at least one damping spring, a damping mass, and a mechanism housing. The oscillation-damping device has at least two retaining parts that at least partly enclose the damping mass. | 10-11-2012 |
20120279741 | VARIATION OF THE NATURAL FREQUENCY OF VIBRATORY MEANS IN ELECTRIC TOOLS - 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. | 11-08-2012 |
20120318551 | Hand-Power Tool Comprising an Oscillation-Damping Device - A hand-power tool includes at least one oscillation-damping device that has at least one damping spring and a damping mass. The hand-power tool also includes a drive mechanism and a mechanism housing. The mechanism housing has a housing cover which is provided for closing a chamber in which the drive mechanism lies, and the housing cover has at least one fixing mechanism that at least partially fixes the oscillation-damping device in at least one operating state. | 12-20-2012 |
20150040341 | Hand-Held Power Tool Suction Extractor Apparatus - A hand-held power tool suction extractor apparatus comprises at least one fastening unit configured to mount on a hand-held power tool. The at least one fastening unit includes at least one holding element configured to be positioned on the hand-held power tool and at least one fastening element configured to exert a holding force on the at least one holding element. The at least one fastening unit also includes at least one movably mounted position fixing element configured to fix the at least one fastening element. | 02-12-2015 |
20150129248 | Percussion Unit - A percussion unit for a rotary hammer and/or percussion hammer includes a control unit that is configured for open-loop and/or closed loop control of a pneumatic percussion mechanism. In at least one operating state in which the control unit changes from an idle mode to a percussion mode, the control unit is configured to adjust at least one operating parameter temporarily to a starting value. | 05-14-2015 |
20150135306 | Electric Tool - The disclosure relates to an electric tool, particularly a hand-held power tool, comprising a control unit which has control software with control parameters, and is provided for the purpose of controlling a drive unit. According to the disclosure, said electric tool comprises an interface unit that is provided to fundamentally update and/or modify the control software and/or the control parameters. | 05-14-2015 |
