I'm not sure what you're trying to prove here. The unadorned word 
"frame" does mean inertial frame. One doesn't have to go around sticking 
the word "inertial" in everywhere. But this is English, not math. One is 
free to qualify the word "frame" with the word "accelerated", without 
introducing any contradiction.

Physicists don't usually concern themselves with accelerated frames, 
because they represent a needless complication. However the OP is 
discussing an accelerated frame.
