  • Patent number: 6039639
    Abstract: A motor driven hand tool has an oscillatory work tool carrier (10) that is attached by means of elastic supporting members (11 to 14) to the housing. Each elastic supporting member (11 to 14) includes a one-piece plastic part consisting of approximately rod-shaped spring elements (20 to 25) and transversely extending base parts at opposite ends of the spring elements. At least one damping part (29) may be provided extending between the spring elements (20 to 25) and bears on or is supported between both base parts (15,26).

  • Patent number: 5496207
    Abstract: An orbital disk grinder comprises a housing, grinding disk which can be applied to a working surface, a motor for moving the grinding disk so that the grinding disk gyrates in a circular orbit and simultaneously rotates about its axis, and speed control means operative for setting a speed of the grinding disk low when a normal force acting on the working surface is low, and high when the normal force acting on the working surface is high, so that a normal force acting on the grinding disk serves as a setting variable of the speed control means.
