This is the problem with the name.
When Sabbath and Purple started out, the term was heavy rock, or hard rock, rather than heavy metal.
Bad Company came later, and I wouldn't put them in any category of heavy.
Deep Purple are not what would be described as heavy metal, but they were one of the early bands that made popular the loud, hard, rocking style that developed into metal. It really was Sabbath, Purple, and Zeppelin that were tagged together, and really only Sabbath were genuinely heavy.
