The door has an opening angle of 110° and is supported on both sides by tension springs. The aim is to create a suitable manual force curve for different door panel weights (here: 2 to 8 kg) with the help of the adjustably mounted springs. A suitable manual force curve is positive at the beginning (when closed), i.e. force must be applied to open the door at first, and becomes negative at about 15-20° opening angle and then remains negative, i.e. the door opens by itself all the way to the end.
The six-bar linkage was previously created with the corresponding synthesis tools in ASOM v7 (two-plane synthesis).
