US Patent 7794337 Tackling dummy

The tackling dummy includes a slide having a ground-engaging skid and an upward extending frame configured to receive a channel formed in an anthropomorphic body having a front side and a relatively narrower profile side. The channel extends upwardly into the anthropomorphic body from a lower side thereof and engages the upwardly extending frame for positioning the anthropomorphic body in one of two primary configurations relative to the slide. These configurations are rotationally spaced about the longitudinal axis of the channel approximately 90° from one another.
