Refrigerator ice tray

Green trays (rockers), blue knob (input crank) and pink conrod create a double parallelogram mechanism. Turn the knob to flip the trays for removing pieces of ice. Torques of red coil springs and the contact between the pink conrod and trays determine horizontal and flipping positions of the trays. At flip position increased torque of the springs twists the trays and separates pieces of ice from the trays. The video was made based on the ice tray of Samsung refrigerator RT25M403358
