Claims

[Scope of utility model registration request]

A long and slender rod whose width direction is almost perpendicular to the door surface and whose length direction is almost perpendicular to the edge of the door, so that it is movably guided in the length direction at the upper edge of the door and projects outward. a center latch rod biased in the direction of , a first retractable latch piece that overlaps with the center latch rod and is swingably supported by a first support shaft perpendicular to the center latch rod; The second support shaft provided allows the first support shaft to be
A second retractable latch piece is provided on the opposite side of the retractable latch piece and is supported in a swingable manner so as to overlap with the center latch rod, and one of the center latch rod and the retractable latch piece is opposed to the other. Due to the engagement between the connecting pin planted on the surface and the long hole opened on the other side,
The center latch rod and the retractable latch piece are interconnected, and in a normal state where no external force is applied to the retractable latch piece, its outer edge protruding from the upper stile of the door is almost perpendicular to the edge of the door. In the extending latch device, a connecting rod extending vertically along the free edge of the door is integrally connected to the center latch rod, and a locking position that interferes with the lower end of the connecting rod is set. It is characterized by providing a locking member that is guided so as to be movable between an unlocked position that does not interfere with the door, and a locking position that moves the locking member from the unlocked position to the locked position in conjunction with the latch for locking the door. A latch device with a locking function.
