Description

  The present invention relates to a double door, and more particularly, to a double door having a frame and a pair of doors supported by the frame so as to be opened and closed.

  Conventionally, a double door represented by a parent-child door having two large and small doors is known. This double door allows both of the two doors to be opened when carrying or unloading large items, and closes one door (child door) during normal use. The other door body (parent door) can be opened and closed in a state where it is locked so as not to move. And as a locking device which locks one door body with respect to a frame, what is called French dropping is common (for example, refer to patent documents 1). In addition, a normal double door is provided with a lock (so-called door guard, chain lock) that restricts the open range of the other door body in a state where one door body is locked to the frame body.

  In the double door described in Patent Document 1, after inserting the hand through the gap of the door body in the state where the door guard is hung and unlocking the locking device (dropping in France), both door bodies are rotated to remove the door guard. In order to prevent unauthorized unlocking that the door is opened by being removed, the locking device is provided with unlocking preventing means (lock mechanism) that cannot be operated with bare hands. This lock mechanism has a lock body that can be operated with tools such as a screwdriver, and this lock body prevents unauthorized unlocking by restricting the movement of the operating part (operating lever) of the locking device. Thus, it is intended to improve the security of the double door.
