Description

  The present invention relates to an auxiliary lock for locking and unlocking the hinged door separately from the existing lock, and an auxiliary lock using the auxiliary lock.

  When renovating a room such as an apartment or condominium, or when guiding an apartment or condominium room for a preview, the contractor or real estate agent holds a number of room keys for each room. Open and close. In this case, it is necessary to carry and use a large number of keys, which is very inconvenient and may be lost.

  As an example of measures against such a problem, an auxiliary lock device is known in which a hinged door is temporarily installed and unlocked with a simple lock such as a padlock without using an existing lock. This type of auxiliary lock device has a configuration in which a padlock or the like can be easily attached without processing the hinged door (hereinafter also referred to as “door”) and the door frame (hereinafter also referred to as “door frame”). Yes. More specifically, for example, as described in Patent Document 1, the front end of the mounting plate fixed to the door frame with a screw tightening force inside the door is exposed to the outside from the gap between the door and the door frame. It is configured to project and lock a lock bar such as a padlock through a lock bar insertion hole formed in both the tip part and the locking metal fitting fitted thereto.

  In such an auxiliary lock device, in order to prevent confinement in the room due to mischief locking or the like, a security lock has been proposed that enables emergency escape from the room at the time of locking (for example, see Patent Document 2). .

  The security lock described in Patent Document 2 is attached to the door frame side of the door with a locking member holding piece protruding in the opening direction of the door through an attaching portion, and the locking member is attached to the locking member holding piece, Locking is performed by bringing the locking member into contact with the door, and the lock plate is disposed on the mounting portion so that the lock plate can be pushed down against the urging force of the spring. By engaging a locking hole formed on the base end side of the locking member holding piece, the locking member holding piece and the mounting portion are integrated, and the lock plate is resisted against the biasing force of the spring. The locking member holding piece and the mounting portion are placed in the chamber by releasing the fitting between the locking claw formed on the lock plate and the locking hole formed on the proximal end side of the locking member holding piece by pushing down. Lockable member configured to be separable on the inside When the locked state, in which the locking member holding piece and the mounting portion is to be unlocked and separated by the indoor side.
