US Patent 11319752 Percussion device

A percussion device including an input side and an output side, the input side is configured to be rotationally driven and the output side is rotationally driven by the input side via a drive transmitter/drive transmitter pathway combination, where the percussion device includes a percussion impactor, an impactor shaft and a percussion anvil; in use, where the output side has restricted, or no, ability to rotate, the drive transmitter/drive transmitter pathway combination increases the distance between the percussion impactor and the percussion anvil until the drive transmitter/drive transmitter pathway combination releases the percussion impactor, where the percussion impactor includes at least one impactor impact tooth and the percussion anvil includes at least one anvil impact tooth, wherein each impact tooth includes an angled impact surface, such that complementary impact surfaces are configured to pass a percussive and/or rotational impulse from the percussion impactor to the percussion anvil.
