Description

  The present invention relates to an auxiliary lock having a chain of an appropriate length, a wire rope of an appropriate length, or an appropriate length of rope attached to an auxiliary lock.

  Conventionally, door chains and door guards for house doors have been used to prevent entry from the outside.

  However, recently it has become a well-known fact that you can easily unlock the door chain and door guard with rubber straps etc. if you can unlock it, it has been publicly released on video sites such as YouTube. There was a drawback that it no longer played the role of a door guard. Originally, doors and door guards in the house were designed to prevent intrusion from outside, but the fact that the door chains and door guards were easily broken did not fulfill their original role. It is safe to attach two or three auxiliary locks, but it is difficult to improve the door if it costs money or is rented.
