Description

Furniture locking device capable of emergency release without damage {FURNITURE LOCKING DEVICE CAPABLE OF RELEASING EMERGENCY WITHOUT DAMAGE}

The present invention relates to a locking device that allows the locked personal lock to be easily removed using a master key in an emergency and returned to its original state, and the lock can be separated from the door when unlocked in an emergency.

In kindergartens, elementary, middle and high schools, libraries, waiting rooms, sports facilities, etc., lockers (storage boxes) equipped with individual locking devices are installed to store each user's items for user convenience.

These personal lockers (storage boxes) are equipped with a locking device on the door so that they can be locked with a personal lock to protect the items from others. With this locking device, a locking ring is formed on the door for locking. By locking the ring, individual users can maintain or unlock the locker.

However, in this conventional locker management, if an individual user loses the key to the locker assigned to him or her, the items stored in the locker cannot be used until a locksmith is called.

In addition, when an individual user uses a special lock, problems arise in storage box management, such as having to dismantle or damage the door of the storage box.

To solve this problem, Republic of Korea Patent No. 10-0947251 (hereinafter referred to as 'Patent Document 1') has been proposed.

Patent Document 1 includes a first operating unit including a lever, a first movable piece, and a lock fixing piece in a locking body, and a second operating portion that moves the locker regardless of the lock setting of the first operating section through a master key. It is configured so that the user can normally maintain the locked state of the door by locking the lock fixing part of the first operating part, but can unlock the door using the master key when special circumstances arise in which the lock cannot be opened.

However, the above-mentioned patent document 1 only performs the role of temporarily opening the locked state of the door using a master key.

In other words, if a lock on a locker, etc. is lost or a situation occurs where the user is unable to unlock the lock while it is locked, in order to use someone else's lock, the lock must be cut with a professional tool or the lock must be removed by cutting the lock on the locker's door. A problem occurred that required actions such as damage, removal, or replacement.

In order to solve this problem, Republic of Korea Patent No. 10-2503421 (hereinafter referred to as 'Patent Document 2') has been proposed.

Patent Document 2 forms first and second ring portions in which a lock is coupled, but the second ring portion has a structure that can slide, thereby making up for the problem of Patent Document 1 by sliding the second ring portion.

The purpose is to improve economic efficiency by preventing damage to doors and doors.

Another purpose of the present invention is to increase the accuracy of operation through a power transmission system in the form of gears and latches, and to prevent malfunctions by ensuring accurate power transmission, and to operate by limiting the rotation and rotation of the ring part. It has a mechanism that allows it to operate without malfunction without causing injury to the user during use.

Another object of the present invention is that when the master key part is rotated, in the process of moving the operation cover part, the ring part rotation operation jaw of the operation cover part comes into contact with the locking operation jaw and the ring part is automatically rotated, so that the user can simply operate the master key part. The purpose is to improve user convenience by allowing the lock to be removed by rotating the ring portion.

The present invention requires unlocking of the door in a state where the lock is locked by the lock and hook of the second case, or in the case of an individual locker, the user loses the key, is not contacted for a long period of time, or the owner of the individual locker changes. If the lock has not been removed despite this, the lock can be easily removed using the master key.

In addition, the lock can be easily removed from the lock and hook of the second case using the master key, preventing the time and cost incurred by cutting and removing the existing lock and damage to the locker and door that may occur when removing the lock. Economic feasibility can be improved.
