  • Vibration reduction apparatus for power tool and power tool incorporating such apparatus
    Patent number: 7322428
    Abstract: A handle assembly for a power tool is described and includes a first substantially tubular body portion 210 which contains a first spring 212. A second body portion 216 is slidably mounted within first body portion 210 and contains a second spring 218. A third body portion 222 is also slidably mounted within first body portion 210. The biasing coefficient, or spring constant, of the first spring 212 is less than that of the second spring 218. The first, second and third body portions 210, 216 and 222, and first and second springs, 212 and 218, are all mounted coaxially on threaded bolt 224. In use the third body portion 222 moves within first body portion 210 in a direction towards end portion 214 and the first and softer spring 212 becomes compressed more rapidly than the second and harder spring 218.
