I wrote earlier: "My potential apology in advance. Can't find my long-unused German-English Dictionary at the moment. Might have to do an update later to correct the record."
Well, here it is. Still couldn't find my German-English dictionary, so I punched in "Kegel" on wikipedia[dot]com (English language version). Nothing at all about "cone" there, but much about bowling, German-style. Slight correction: per Wikipedia, "Kegel" translates as both the game and the German bowling pin. (For some reason, both the spelling and pronunciation in my area of residence added an "n" for the last letter. Local dialect, perhaps?} Wiki had some additional unrelated meanings for the word, including the exercise recommended by pre-natal instructors.
