Description

  The present invention can be attached to a door handle lever handle or a handle ball lock, displays a vacant house, and covers an existing lock hole to prevent an unlocking action by picking. About.

  In recent years, vacant rooms such as rental apartments, condominiums, and housing complexes in housing estates have sometimes been abused as destinations for collecting money for money transfer fraud and bank fraud. For this reason, it is necessary to inform a delivery company or the like that the house is an empty house, and a method such as sticking a sticker on which “delivery strictly prohibited” or the like is attached to the entrance door is used.

  Further, in order to prevent unauthorized persons from unlocking, a picking prevention metal fitting that closes the door lock key hole by covering the door knob with a cover or the like and prevents the door handle from rotating is proposed. (Patent Document 1).

  The picking prevention metal fitting described in Patent Document 1 divides a knob cover body in which a disk is coupled to a cylinder that covers a small diameter portion on the back side of a door knob, and divides the divided knob cover body into pins in a rotatable manner with pins. Cover the padlock with a disk centering on the center, and provide a pair of holes that come into contact with and facing the cylindrical part of the small diameter part or the tongue provided on the disk, and padlocks such as padlocks in the state where the lock is covered with a disk. It can be locked through.
