Title:
ドアクローザ機構
Document Type and Number:
Japanese Patent JP6776838
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a door closer mechanism capable of preventing switching power that is accumulated by working together with an opening operation of a door from acting to cause the door to operate in a closing manner.SOLUTION: A door closer mechanism 15 comprises a power mechanism 16 which performs, along with a closing operation of a swing door, a power accumulating operation so that the power mechanism accumulates a switching power that switches a latch mechanism 20 from a half-latch state to a full-latch state by working together with an opening operation of the swing door. Also, the power mechanism performs a releasing operation so as to release the latch mechanism 20 by working together with the fact that the latch mechanism is switched to the half-latch state. Further, the door closer mechanism 15 comprises a power transmission device 18 that transmits the releasing operation of the power mechanism 16 with respect to the latch mechanism 20. Furthermore, the door closer mechanism 15 comprises a restriction mechanism 17 which allows for the power accumulating operation of the power mechanism 16 during a period from when the swing door is caused to operate in an opening manner to when the latch mechanism 20 is switched to the half-latch mechanism, and which restricts a returning operation with respect to the power accumulating operation.SELECTED DRAWING: Figure 2
