how to make a swing hinge rig

Question

hello guys does anyone know how to make a rig to make swing hinge like this? https://www.dropbox.com/s/bdj4bj9rcqxoy7e/window.mp4?dl=0

here i tried with damped track, i added two with 1.000 and 0.000 of head/tail influence, but still is not convincing the rig...

I made the swing system with IK constraint.

Creation procedure

Creation of arm system proceeded as follows:
Step 1: Simple arm system (Armature)
Step 2: Design drawing (Mesh)
Step 3: Basic arm system (Armature)

Bone (Controller): Limit Rotation
Bone.002: IK constraint
Bone.003: Copy Rotation and Transformation

The Transformation constraint was used to absorb the bone length matching error. It is very difficult to exactly match the bone length a + b = c + d.

With offset between Bone and Bone.003 length.

$\begingroup$ @tetti check this file, maybe you can try to improve this rig to be accurate as possible drive.google.com/file/d/1-0_XSdkzt3cbRstBiiuESUoZh92EQ2Dx/… $\endgroup$

$\begingroup$ Unfortunately it doesn't physically work with the mesh objects.I'll upload a working example later. $\endgroup$
