Patent number: 8672305Abstract: A work apparatus has at least one handle (12) and a drive motor (3). The handle (12) is connected to said drive motor (3) via at least one anti-vibration element (16, 17, 18, 19, 20). The anti-vibration element (18, 19) is held on a first housing part and coacts with a second housing part. To achieve good damping, the anti-vibration element (19) includes a damping section (25) having an annularly-shaped wall (37) which expands in the direction of the second housing part.Type: GrantFiled: September 24, 2010Date of Patent: March 18, 2014Assignee: Andrea Stihl AG & Co.

Patent number: 8225514Abstract: A manually guided implement, such as a power saw, a cut-off machine, or the like, having a drive motor for driving a tool of the implement. The drive motor has a drive shaft that is rotatably driven about an axis of rotation. The implement has a handle on which is disposed at least one control handle for the drive motor. Formed between the handle and the drive motor is a vibration space that is spanned by at least one anti-vibration element, at least one of which includes a coil spring, the longitudinal axis of which is disposed approximately perpendicular to a longitudinal plane of the implement. The vibration space is spanned by at least one connecting element, the longitudinal axis of which is inclined relative to a transverse plane of the implement that is disposed perpendicular to the longitudinal plane.Type: GrantFiled: May 5, 2008Date of Patent: July 24, 2012Assignee: Andreas Stihl AG & Co., KGInventors: Andreas Guip, Johannes Menzel, Helmut Lux, Günter Wolf

Patent number: 7941930Abstract: A hand-held power tool has a motor housing with drive motor and a grip housing with a longitudinal support and a forward grip. The motor housing and the grip housing are connected to one another by antivibration elements. The forward grip has a connecting end that is connected by a screw connection to the longitudinal support. The screw connection has at least one fastening screw that is positioned in the operating position of the power tool in a vertical direction of the power tool. The screw connection has a metal insertion part that is positioned entirely within the contour of the longitudinal support that is a plastic part. The metal insertion part has a screw receptacle for the at least one fastening screw. The at least one fastening screw is fixedly screwed into the metal insertion part.Type: GrantFiled: November 30, 2009Date of Patent: May 17, 2011Assignee: Andreas Stihl AG & Co.

Patent number: 7293330Abstract: A tubular handle for a manually guided implement, especially a power chain saw or the like, is provided. The handle has an essentially circular cross-section and at least one mounting portion for fixing the handle to the implement. In the area of the mounting portion, the circular cross-section is flattened to form an at least approximately planar abutment portion, beyond which a circular cross-sectional portion is retained. The abutment portion is provided for fixing the tubular handle to the implement.Type: GrantFiled: December 14, 2004Date of Patent: November 13, 2007Assignee: Andreas Stihl AG & Co.

Publication number: 20060005357Abstract: A handle of a hand-held working tool has a handle pipe made of a laminate with fiber-reinforced plastic material. The handle pipe is reinforced by a locally adjusted laminate structure at locations of high dynamic vibration-caused deformation energy, respectively. The laminate of the handle pipe has a base laminate and an additional laminate provided at the locations of high dynamic vibration-caused deformation energy. The additional laminate is applied to the exterior of the base laminate.Type: ApplicationFiled: June 17, 2005Publication date: January 12, 2006Applicant: ANDREAS STIHL AG & CO.
