I had another idea today while I was....ahh...standing around. A square technic
beam may be able to hold the coupler straight. If a peg is place in the hole
second (maybe the first hole would work to) from the end of the beam in pull
mode the peg would be pulled forward and the assembly would be free to pivot.
In the push mode the peg would allow the beam to be pushed back against a flat
surface which would hold it in place. For the beam to pivot the peg has to be
able to slide forward. If a corner pushes the beam side ays with engough force
then the beam has no choice than to be pushed forward.
I'll let you know if it works.
