Portable doorframe mounted Chin up bar?

Does anyone know of a good portable chinup bar that doesn't require any permanent mountings? We live in a studio apartment which is very open and only has one usable doorframe (bathroom door) so I'd need to be able to remove it when I'm finished.

I don't need anything too heavy duty. There must be some sort of clever mounting technique that makes this feasible.


Thanks in advance

They do exist. I used to have one ( unforunatly it disapeared during a move:( ).

It just wedged in a door frame by twisting it and locking it in place. It worked well...then again i'm somewhat light. I'm not sure how it would work if you are heavy. My friend used it and he was around 170lbs.

I'm sure a fitness depot type store would have something like that.

I think mine was found online, check there. It has 2 screws that go in the frame, and then like Deeb mentioned, it tightens into place. the only thing that sucks is since it is in a doorway your limited to close grip.
good luck.
