VIBRATION ISOLATION HANDLE FOR HAND CARRY POWER TOOL

摘要

PROBLEM TO BE SOLVED: To provide a hand carry power tool which is electrically, pneumatically, or hydraulically driven, for use when the operator carries out various types of work by directly gripping a handle thereof, wherein the power tool minimizes transmission of vibrations occurring at the time of boring, cutting, or grinding work to the operator, and has improved handling performance.;SOLUTION: The handle consists of a handle portion 1 made of a material of relatively high rigidity such as a resin, and a handle portion 2 made of a material of relatively low rigidity such as an elastic body. The handle portion 2 has a core bar 3 formed in one body therewith, which is integrally formed with a hexagonal rotation stop portion 3a and a screw portion 3b. To assemble the vibration isolation handle, the core bar 3 formed in one body with the handle portion 2 is inserted into a rotation stop hole 1a formed in the handle portion 1, and the rotation stop hole 1a formed in the handle portion 1 has a hexagonal shape similarly to the rotation stop portion 3a of the core bar 3, whereby the handle portions 1, 2 are prevented from rotating with respect to each other after the insertion of the core bar.;COPYRIGHT: (C)2004,JPO&NCIPI
