Joint & Motion problem

[manolo.dev]

Hi, trying to model a Bed/Desk but I can not make the movable feet that will join the desk to move by like gravity.

I mean when the bed is moving the desk should move in a way that everything in the desk don't fall.

Better to visualize in the picture no.2 , the arrow shows where the feet should be when the bed is moving up.

I- All parts are components.

II- 

II- Part no. 3 is the desk feet (will be joint rigid with the desk) it is joint Revolute to the part 2 (leg) and should move against to the bed movement, keeping the desk horizontally.

III- the supports in gray are not connected yet.

IV- both feet have joint Revolute joint they have to move together. 

What am I doing wrong?

Any help is more than welcome.

Hey manolo.dev,

The simplest answer here is probably Motion Links. There are plenty of videos on it on Youtube. https://www.youtube.com/results?search_query=fusion+360+motion+links

Your pics do not make sense to me,  Rigid Joint markers in space, and Revolve Joint on no 3 but one part there.

Maybe with The file or screencast we can help.
