Patent number: 8162075Abstract: A powered hammer includes a body in which is disposed a motor and a hammer mechanism driven by the motor when the motor is activated. A tool holder is coupled to a front portion of the body and which is capable of holding a cutting tool. The hammer mechanism, when driven by the motor, is capable of imparting impacts to a cutting tool, when held by the tool holder. A handle is moveably coupled to a rear portion of the body for movement toward and away from the body along a tool axis of the tool holder. The handle includes a grip portion and first and second end connection sections coupled to opposite end portions of the grip portion. The first and second end connection sections are slideably mounted on first and second arms that project rearward from the body. A movement control mechanism is mounted inside the handle and coupled to the first and second arms and the handle.Type: GrantFiled: July 25, 2008Date of Patent: April 24, 2012Assignee: Black & Decker Inc.Inventors: Ana-Marie Roberts, Norbert Hahn, Ralf Seebauer

Patent number: 7789168Abstract: The disclosure describes a handle assembly for a power tool that includes attachment means for attaching the assembly to a housing of a power tool. The handle means is adapted to be held by a user of the power tool and the handle means is mounted to the attachment means and is capable of limited movement relative to the housing of the power tool. The vibration damping means acts between said housing and said handle means. The vibration damping means can also comprise elastomeric material. The attachment means can be mounted in use to the housing via a bolt on one of the attachment means and the housing passing through a respective aperture in the other of said attachment means and the housing. At least some of the elastomeric material is arranged in use between at least one said bolt and a corresponding said aperture. The handle means can be pivotable and/or slidable relative to said attachment means. The vibration damping means can comprise at least one spring (e.g., compression/spring or torsion spring).Type: GrantFiled: March 26, 2008Date of Patent: September 7, 2010Assignee: Balck & Decker Inc.Inventors: Reimund Becht, Norbert Hahn, Michael Stirm, Ralf Seebauer
