Publication number: 20020070564Abstract: A door closer includes a latch that engages with a striker and first and second ratchets that engage with the latch. When the latch receives the striker and rotates from an initial position to a fully latched position, the door is moved to a fully closed position. When the ratchets disengage from the latch, the latch returns from the fully latched position to the initial position. The striker thus disengages from the latch, and the door moves from the fully closed position to a released position. After the ratchets disengage from the latch, each ratchet is held at a position at which the ratchet cannot engage with the latch unless the door is located at a predetermined position separate from the released position in a door opening direction.Type: ApplicationFiled: August 23, 2001Publication date: June 13, 2002Inventors: Satoshi Ohta, Takayoshi Aoyama, Toru Yoshida, Tadashi Isozumi
