Description

Door Locks {Door Locks}

The present invention aims to make it impossible to unlock when using a tool other than a key suitable for the locking device.

In other words, the cylinder and its inner cylinder and the pins corresponding to each other are aligned with iron wires or similar tools through the keyholes to prevent them from being released, and other purposes include inserting special tools into the keyholes. The purpose is to force the cylinder to be released by breaking the pin.

Another object is to form a curved key way between the key hole and the cylinder and the inner cylinder and those including the pins, thereby forming the inner cylinder at the key hole. Special tools can be inserted up to the keyhole formed in the pin to prevent pin alignment or forced rotation of the inner cylinder.In particular, the flexible key passing through the curved key way is fixed to the curved key through tube. Even though it is (No Key Plug), it aims to open and close by rotating 360 ° in a curved key through tube.

In general, the locking device that can lock or release the locking device is divided into an integral locking device that is integrally formed with the handle and an auxiliary locking device that is manufactured separately from the handle and installed on a surface.

1 illustrates an integrated locking device among these locking devices, which is embedded in the door 300 and has a latch bolt 260 and a dead bolt 250 that are embedded in a coupling groove formed in the door frame 340. Is mounted on the front surface of the main body 200 and the outdoor facing to the wandering is configured to include a handle 290 and a lock 190 connected to the latch bolt 260 and the dead bolt 250 respectively. .

In addition, the cylinder 3 is screwed to the main body 200 so as to be exposed to the front of the door 300 and rotatably mounted in the interior of the cylinder is integrally connected to the dead bolt 250, the central portion in the longitudinal direction A plurality of pins 91, which are divided into an inner cylinder 4 and an upper pin 92 and a lower pin 91 having a key hole 42 formed therein, and penetrated and coupled to the cylinder 3 and the inner cylinder 4 at the same time. 92).

The pins 91 and 92 are coupled to pin holes formed so as to correspond to the cylinder 4 and the inner cylinder 3, and are elastically pressurized by the spring 9 so that their ends protrude into the inside of the key hole 42. The upper pin 92 is caught in the pin hole to prevent the inner cylinder 4 from rotating. Then, when the key 100 is inserted into the key hole 42, the boundary surface of the upper and lower pins 92 and 91 is connected to the boundary surface of the cylinder 3 and the inner cylinder 4 by the curved surface of the key 100. Since it is aligned along, the inner cylinder 4 can be rotated. Accordingly, when the key is inserted into the key hole 42 and the inner cylinder 4 is rotated, the dead bolt 250 connected to the rotation shaft of the inner cylinder 4 is backwardly inserted into the door lock so that the lock can be released. . By the way, the door lock device is configured such that when the cylinder inner cylinder 4 is integrally connected to the dead bolt 250 to rotate the inner cylinder 4, the dead bolt 250 is reversed to unlock the door. do. Therefore, if an intruder inserts a screwdriver or the like into the key hole 42 of the inner cylinder 4 and then forcibly rotates the screw that fixes the cylinder 3, the screw is broken or bent to rotate together with the cylinder 3 or in the inner cylinder. The upper and lower pins are damaged and the dead bolt is reversed because the inner cylinder 4 is rotated so that the door lock can be unlocked, and outsiders can easily insert special tools into the inner cylinder keyhole 42 The pins 91 and 92 are aligned and unlocked as if they were opened with a key. Another conventional technique is to prevent the key-cylinder used in automobiles from entering the key-cylinder inner cylinder such as dust, rain or snow. Cover the insertion hole with the dust cover and cover the spring-loaded dust cover so that it can be opened when the key is entered. When the key is plugged in, the cover will rotate about one axis to open and the key will pass through, Key-Cylinder The inner cylinder keyhole has been put in place, but this also allows an outsider to insert a special tool into the inner cylinder keyhole and align a number of pins on the inner cylinder to unlock it as if it were opened with this key. Can be. As such, a simple tool such as a screwdriver or a special tool may be used to damage the door lock device or align a plurality of pins in the inner cylinder to unlock the door within a short time, thereby causing an outsider to easily invade the door. Another conventional technique is U.S. Patent Publication No. 05086632 (Flexible Key and Lock Assembly), which has a keyhole with a curved key way and a key that allows the key to be deflected so that it can be inserted therein. A flexible key formed of a flexible elastic surface or the like is provided. This allows pins in curved key penetrations to keep wires and similar tools out of the way, preventing outsiders from unlocking without this key, but flexible keys are not linked or flexible. Since it is made of elastic surface, it must be left, right, or up and down because of the hinge characteristic. To insert the flexible key into the curved key through tube, it must be inserted in the direction of refraction of the key. Even if the pins are aligned, the flexible key cannot be rotated in the curved key passage.

Therefore, if there is a key plug, the flexible key contained in the curved key through tube must be rotated up to the key plug. As the curved key through pipe becomes more complex, the key plug may be larger, and a plurality of pins may be broken when an outsider forcibly rotates the key plug, which may be released without the key. Although there is an example of the No Key Plug (7A), it is necessary to insert a flexible key on both sides of the door lock and only align the pins. It is feed and its use is limited. In general, flexible keys must be selected up, down, left, or right. Such refraction can cause the flexible key to rotate in a curved key through tube with the key plug fixed. There is a problem that can not be opened and closed.

In order to solve the above problems and to achieve the object of the present invention, the technical problem of the present invention is to provide a gap between a keyhole and a cylinder, and an inner cylinder and a plurality of pins attached thereto, so that an outsider can make a wire or an all-rounder. The development of technology and other technical problems that make it impossible to align a number of pins with a key, etc., has a rotating body with a locking portion at the upper portion of the inner cylinder keyhole even if the pins are aligned, so that the inner cylinder can be rotated if the locking portion of the rotating body is not solved. It is a technology development that can not be solved.

Another task is to form a curved key way between the key hole and the inner cylinder key hole inserted into the cylinder. In order to achieve the development of a flexible key capable of rotating only 360 ° of a key in a state in which a flexible key passing through the curved key way is fixed (no key plug), It is a task.
