Title:
LATCH DEVICE AND DOOR DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2018112042
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a latch device with a structure capable of having a locking function with a simple structure.SOLUTION: A latch device 101 of a door 31 attached to a door frame 21 of a building, includes: a striker 111 provided to a door frame 21; a latch member 122 which engages with the striker 111 in a state the door 31 is closed to prevent the door from being opened; and an actuator that drives the latch member 122 in a direction where the engagement with the striker 111 is released. The latch device is configured so that the actuator is activated responding to an instruction to release the latch to drive the latch member 122 in a direction where the engagement with the striker 111 is released. Since the latch member 122 does not release the engagement with the striker unless the actuator is not driven, the latch device 101 also has a locking function. In this case, since the latch member 122 is urged in a direction where the latch member engages with the striker 111 by means of a spring force, the locking function is reliably exerted.SELECTED DRAWING: Figure 3
