  • Handle structure for percussive tools
    Patent number: 4036085
    Abstract: A handgrip in a handle structure for hammer tools comprises a wing-shaped portion for applying a thrust force on the tool. The force of the recoil which occurs when impacts are delivered is absorbed by the mass of the hand and arm and by the resilience of the limbs of said parts of the body. To advantage, the handgrip is turned when the pressure-applying-grip is changed to a lifting-grip.
