Description

Closet door lock {The lock for locker door}

The present invention relates to a lock for mounting a closet door that can prevent a secure fastening and unauthorized unlocking of a key and a corresponding lock by a combination of a pin alignment pattern with a simple configuration, and more specifically, a cylindrical type composed of a double cylinder of an inner cylinder and an outer cylinder. In the lock, the key grooves can be formed with various code code patterns on the top, bottom, left, and right sides of the key outer periphery so as to match the arrangement position of the locking pin attached to the inner cylinder (sorting condition). Combination of patterns that do not allow arbitrary unlocking is excellent in user safety and prevents unauthorized rotation by keys modulated by long grooves formed in the outer cylinder. It is impossible to cancel the lock even if it is operated. However, there is an economical effect due to the reduction of manufacturing labor due to the change of the arrangement pattern production and the low unit price.

The lock is a set of keys and is installed in lockers, bathroom cabinets, lockers, lockers or at home or workplace wardrobes, door or desk drawers, safes, etc. to store items such as gyms, health clubs, saunas, saunas, baths and dressing rooms. It is an indispensable tool to protect your property and confidential documents. It is a lock that prevents you from opening it with a key that does not have a true key or does not match the lock pattern of teeth or grooves.

The locks are classified into various types such as word lock, lever tumbler lock, pin tumbler lock, and the like. Among them, the lock release does not work even if the pattern of the key is slightly wrong. Is commonly used.

This cylindrical lock is generally a double structure in which the inner cylinder overlaps in the cylindrical outer cylinder. The outer cylinder and the inner cylinder are formed with a plurality of matching holes in a row, and the lock hole is equipped with pins and springs of different lengths, The pin is pushed downward by the force. When the key that fits the lock pattern is inserted into the key hole of the inner cylinder, the inner cylinder rotates to release the latch.

However, in general cylinder type lock, the cylinder (inner cylinder) rotates only when the height and valleys of the teeth formed in the key correspond to the other pins 1: 1 correspond to the other pins. Is a complex configuration in which teeth of different shapes are formed, the illegal tool such as an illegally modified pseudo key or a pin with a ring is inserted into the keyhole of the lock cylinder, and then the height is properly adjusted by turning and pulling in the keyhole passage. Since the unauthorized user can open the lock by a simple method of arranging the unlocked position, the security is inferior, and the operation of the key is not correct and the key is bent or the latch is broken.

In particular, closets such as bathrooms, jjimjilbangs, and locker rooms, which are used by a large number of unspecified masses, have to change the tooth pattern of the cylindrical key with a toothed structure that is different from similar keys, but it is complicated and coarse using only one side of the key body. Due to structural defects, there was a limit in diversifying the arrangement pattern of pins with safety and failure.

The present invention has been devised to solve the above-mentioned problems, using only one side and deforming only the concave-convex pattern having a different height and shape, so that there is a limitation in the formation of a password pattern, a low workability, and can be easily solved. In order to diversify the pattern of the cylindrical lock and the key, the horizontally arranged pinholes are installed at regular intervals on all sides of the cylinder body of the concentric double structure in which the inner and outer cylinders of the cylindrical shape overlap each other, and coincide with the key groove as the code code. Multi-pattern security structure that locks one or more locking pins in different arrangement positions and installs long grooves in the longitudinal direction of the outer cylinder to prevent unauthorized release.Precision, processability, and similar keys make it easy to adjust various alignment patterns. I'm hook pin, multiple that can't be unlocked by other keys Excellent set of security and aims to provide a good aesthetic standing closet locks for doors mounted so embedded in the side door.
