Abstract

While some may feel that elderly people "cannot be entrusted" with managing cylinder keys as a security measure, in reality, this presents many challenges. [Solution] The hole in the spacer, which has a hole for locking the cylinder key, is aligned with the hole for the carrying strap on the head of the cylinder key, and the wire of the wire padlock is passed through it. The tip of the spacer covers the rear end of the effective key part of the cylinder key, locking it so that the cylinder key cannot be inserted all the way in and rendering the lock inoperable.

MEANS FOR SOLVING THE PROBLEMS

[0005] A rectangular metal tube made of pipe material is attached to the tip of the rear end of the effective key portion of the cylinder key, and toward the rear end, the aforementioned Thin iron plates are attached to the inner sides of both left and right sides of the rectangular metal tube at the tip, and a spacer having a cylinder key locking hole provided in front of the rear end to align with the portable string threading hole arranged in the head portion of the cylinder key is aligned with the portable string threading hole arranged in the head portion of the cylinder key, the wire of the wire-type combination padlock is passed through, the tip of the spacer covers the rear end of the effective key portion of the cylinder key, and the cylinder key is locked in a state where it cannot be fully inserted, making the key unable to perform its function. According to the configuration of claim 1, the wire of the wire padlock is removed from the cylinder keyhole. By removing the cylinder key, moving it to the tip, and attaching the wire to the wire padlock body, the wire padlock can be used as a keychain. [Effects of the Invention]

[0006] If you are using a cylinder lock spacer to lock the cylinder lock, Anyone who does not know the combination to the aforementioned wire-type padlock cannot easily unlock the cylinder lock and therefore cannot use the cylinder lock. [Brief explanation of the drawing]
