Pantograph pull out door mechanism info needed
Kind of car related, its for a truck.
I need to design a vehicle door that pulls out and swings to one side. I believe these are called pantograph hinges. The kind of thing found on race
transporter belly lockers for opening doors parallel to the body.
I have googled for info on them, but all I get is a couple of crappy pictures and no real detail of the hinge mechanism
So has anyone got some good photos of the mechanism, or engineering drawings?
I am going to model the mechanism on Solidworks, but I need a good starting point. Can you locostbuilders help?
Thanks in advance.

why not use the hinge from an old coach bus door? like this -

Thats the sort of thing I want, but I need details of the actual mechanism.
Or this...
but again, I need details of the mechanism only

Amagingly if you do a google images search for "pantograph door hinge"... it magically brings up quite a bit of information... some of it
looks like it might be relevant!

Isn't what you are looking for a parallelogram, as opposed to a pantograph?
Pantograph is just a scissor mechanism as on the pick-up on leccy choo choos.
Or something like this any good?:

Done that already. And I've looked at the cupboard door page too
I need to engineer one of these, so need details of the shape of mechanism. All the links and google are surprisingly short of good information.
Parallel motion or pantograph both similar, if not the same??? so I'm not bothered what its called, I just need info on the mechanism on a door
that pulls out and moves in a parallel action to the side.
