3 blade scissor axis mechanism ?

Question asked by Shar Fa on Dec 28, 2014

Hello guys,


I'm trying to think about a mechanism to create a scissor-like motion with 3 blades.

Does anyone has an idea how to make the axis that connects the 3 blades so they all move in same proportion while pushed or pulled (keeping a 120deg angle looking from the side plane).

I don't mind if the axis moves along the blades (which are cylinder shaped) in the motion as long as it gets the job done.


Would love example for existing products if you have one in mind.
