Abstract (en)
A concentric cross mechanism for transiting torsion includes a main body unit of a concentric cross mechanism, a main body unit of the torsion-driven mechanism, a main body unit of the force-generating mechanism, and a restriction device. A center point is defined by crossing a vertical concentric axis and a horizontal concentric axis. The axle of the driven bevel gear and the scroll springs spin reversely with the axle of the torsion-generating bevel gear. The first bevel gear is provided for outputting the torsion on the upper and bottom ends thereof. Furthermore, when the rotary rod connected with one side of the torsion output axle is disposed in the positioning block, the door is driven by the other side of the torsion output axle to swing in a predetermined angle.
