  • Patent number: 8025197
    Abstract: A driving tool that includes a frame, a motor assembly and a resilient member. The motor assembly is coupled to the frame and includes an electric motor, a flywheel driven by the electric motor, a pinch roller and a driver disposed between the flywheel and the pinch roller. The pinch roller is selectively movable from a first position to a second position to drive the driver into engagement with the flywheel. The driver is movable between a returned position and an extended position. The resilient member is coupled to the frame and biases the driver away from the flywheel to reduce or eliminate contact between the flywheel and the driver when the flywheel is at rest, the driver is in the returned position and the pinch roller is in the first position. A method for operating a driving tool is also provided.

  • Patent number: 7138595
    Abstract: A hand-held power tool with a housing with a handle arranged along an axis, a trigger disposed in the housing and configured to operate the hand-held power tool, first and second sets of guide tracks coupled to one of the housing and the trigger and first and second sets of guides coupled to the other. The trigger, which includes a contact surface that is configured to be contacted by a finger of a user of the hand-held power tool, is movable between an extended position and a retracted position. The first and second sets of guide tracks guide the first and second sets of guides, respectively, such that movement of the trigger from the extended position to the retracted position causes the contact surface to move in a substantially constant direction having a first directional component and a second directional component, the first directional component being generally perpendicular to the axis of the handle and the second directional component being generally parallel to the axis of the handle.
