GATE HAVING AUTOMATIC LOCKING SUSPENSION LOCK

摘要

PROBLEM TO BE SOLVED: To enable a suspension lock of a gate to be automatically locked by closing the gate.

SOLUTION: A locking side arm 31 of one door 1 of double doors and a handlebar 33 coaxial with the locking side arm 31 are restricted by rotary operation in a state of being energized in a return direction by a lock device 6, and when closing the door 1, a trigger 7 arranged protrusively on a side of the other door 2 of the double doors from an end part of a width face of the one door 1 and energized toward the side of the other door 2 side is brought into contact with the other door 2 to release the above-described restriction. Release of the restriction causes energization of the arm 31 and the handlebar 33 to be returned, and the arm 31 is engaged with an arm receiving part 35 of the other door 2 to perform automatic locking of a suspension lock 3. The release of the restriction performs engagement of a clutch 61 installed on the arm 31 and a lock plate 64 by moving the lock plate 64 by making the trigger 7 face the lock plate 64.
