Abstract
A door closer device comprises a sun gear pivotally mounted via a pivot shaft, a planetary gear which meshes with the sun gear to orbit the sun gear while turning on its own axis, a closing lever pivotally mounted via the pivot shaft and pivotally mounted with the planetary gear, and a sector gear which has an external teeth meshing with an output gear and an internal teeth meshing with the planetary gear. The closing lever swings about the pivot shaft to allow a latch to move from a half-latch position to a full-latch position where the latch fully engages with a striker.
