Title:
地震自動解錠機能付き錠装置
Document Type and Number:
Japanese Patent JP6758639
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lock device with an automatic unlocking function to deal with an earthquake that detects a vibration of an earthquake and is operated reliably to unlock the lock device having a dial lock and a cylinder lock, when the earthquake occurs in a huge scale which inhibits functioning of communication and other infrastructures and both dial lock and cylinder lock are in a locked state, even when an unlocking code of the dial lock is not known and a key of the cylinder lock is not at hand.SOLUTION: With a lock device having an automatic unlocking function to deal with an earthquake, a contact part B21 of a slide part B20 moves through a first vibration transmission mechanism B50 due to a vibration generated when both dial lock A6 and a cylinder lock A7 of a lock device A are in a locked state, causing a pivot shaft part A9 and a contact member A8 to move in a direction against an energizing direction of a first elastic member A91 so as to release a contact between the contact member A8 and a latch A67, thus enabling a grip part A4 to be pulled up.SELECTED DRAWING: Figure 1
