Portable impacting apparatus

An impacting apparatus comprising:

• a frame;
• an arm movably mounted on the frame, the arm having a proximal end mounted on the frame and a distal end being a free end, the arm having an impact location;
• a weight mounted on the arm and rotatable with respect to the arm about a rotation axis eccentric to a center of mass of the weight;
• a weight rotation assembly rotatably mounting the weight on the arm, the weight rotation assembly comprising:
• a rotation shaft mounted on the arm at the distal end and mounted on the weight;
• a clutch configured to transfer rotation of the rotation shaft to the weight if a rotational speed of the rotation shaft exceeds a rotational speed of the weight and permit the weight to freely rotate with respect to the rotation shaft if the rotational speed of the weight exceeds the rotational speed of the rotation shaft;
• a rotation assembly configured to rotate the rotation shaft with respect to the arm to thereby cause rotation of the weight with respect to the arm;
• and
• an impact member movably mounted on the frame and being aligned with the impact location on the arm such that the arm impacts the impact member, the impact member having an impact surface;
• wherein the weight includes two weight plates rotated by the weight rotation assembly in a same rotational direction and being spaced to define a clutch space therebetween, at least a portion of the clutch being positioned in the clutch space.

An impacting apparatus comprising:

• a frame;
• an arm movably mounted on the frame, the arm having a proximal end mounted on the frame and a distal end being a free end, the arm having an impact location;
• a weight mounted on the arm and rotatable with respect to the arm about a rotation axis, a center of mass of the weight being offset from the rotation axis, the center of mass of the weight rotating about the rotation axis in a substantially circular path;
• a weight rotation assembly rotatably mounting the weight on the arm, the weight rotation assembly comprising:
• a rotation shaft mounted on the arm at the distal end and mounted on the weight, the rotation shaft rotating on the rotation axis of the weight;
• a clutch configured to transfer rotation of the rotation shaft to the weight if a rotational speed of the rotation shaft exceeds a rotational speed of the weight and permit the weight to freely rotate with respect to the rotation shaft if the rotational speed of the weight exceeds the rotational speed of the rotation shaft;
• a rotation assembly configured to rotate the rotation shaft with respect to the arm to thereby cause rotation of the weight with respect to the arm;
• and
• an impact member movably mounted on the frame and being aligned with the impact location on the arm such that the arm impacts the impact member, the impact member having an impact surface, the impact member being elongated along a substantially vertically oriented longitudinal axis of the impact member;
• wherein the longitudinal axis of the impact member intersects the rotation axis of the weight and of the rotation shaft;
• wherein the impact member has an impact surface configured to contact an object to which transfer of an impact is desired, the impact surface being bisected by the longitudinal axis of the impact member;
• and
• wherein the longitudinal axis of the impact member intersects the substantially circular path of the center of mass of the weight.
