Description

Door Locking Device {DOOR LOCKING APPARATUS}

The present invention relates to a door locking device, and more particularly to a door locking device using a mortice lock (mortice lock) provided with a dead bolt and a latch bolt.

In general, most door locking devices have a latch that locks and unlocks the door while being infested by a rotating mechanism such as a rotating grip installed on the outside and the inside of the door, respectively. In addition, in order to prevent the instability of the door locking by the latch, the door is locked and unlocked by the dead bolt being released by the rotation mechanism of the rotation means such as the rotation knob or the key rotation means such as the card key reader module, separately from the rotation mechanism of the latch. A dead bolt operating means for locking is installed. As widely used in such a door locking device, a mortise lock having a double locking structure by a latch bolt and a dead bolt is widely used.

However, various door locking devices using such a mortise lock have a problem in that its configuration is complicated and the operation between parts is unstable, so that it can not perform the role of the locking device properly or be damaged when used for a long time.

The present invention is to solve such a problem, the object of the present invention is to provide a new type of door locking device that can operate the dead bolt and latch bolt with a simple mechanical mechanism. In addition, the present invention is to provide a new type of door lock device that the driving is simple, the failure rate is low and the user can conveniently use.

The key assembly 20 includes a key block 22, a key pin 24, a key plate 30, a key plate stopper 32, a key plate stopper spring 34, a latch bolt transformer block 36, and a dead bolt. It consists of a trans bar 38. The key block 22 is connected with the outer and inner rotary grips. The key plate 30 is connected to the key block 22 and is moved in parallel with the traveling direction of the dead bolt 16 and the latch bolt 18. The spring 34 is coupled to the key plate 30 on the key plate stopper 32 to give an elastic force to the key plate 30 in place. The latch bolt transformer block 36 is coupled to the key block 22 to rotate to operate the latch bolt operating member. The dead bolt trans bar 38 is coupled to the key plate 30 to reciprocate to operate the dead bolt operating member. The key pin 24 will be described later, but is operated by an automatic locking member so that the external rotary grip is in a connected state. Since the key block 22 of the key assembly 20 is already known and used, a detailed description thereof will be omitted.

The latch bolt operating member causes the latch bolt 18 to be operated by the key assembly 20 independently of the dead bolt 16. The latch bolt operating member includes a latch bolt shaft 182 and a latch bolt spring 184 to allow the latch bolt 18 to be inserted into the housing 12 and to project outward. The latch bolt shaft 182 of the latch bolt operating member is operated by being coupled to the latch bolt transformer block 36 of the key assembly 20. The dead bolt operating member allows the dead bolt 16 to be operated by the key assembly 20 independently of the latch bolt 18. The dead bolt operating member includes a dead bolt shaft 162, a dead bolt spring 164, a dead bolt bracket 166, and a dead bolt link 168. A dead bolt shaft 162 is connected to the dead bolt 16, the bracket 166 supports the dead bolt 16 and the shaft 162, the spring 162 is on the shaft 162 Is coupled to. One end of the dead bolt link 168 is hinged to the bracket 166 and the other end is hinged to the housing 12 so that the dead bolt (bar) of the dead bolt trans bar (38) of the key assembly (20). Let 16) work out.

On the other hand, the door locking device 10 according to the present embodiment has an automatic locking member. This self-locking member causes the dead bolt 16 to operate when the latch bolt 18 is inserted into the housing 12 and dead when the dead bolt 16 is inserted into the housing 12 by the latch bolt operating member. Fix the bolt operating member so that the position of the dead bolt 16 is fixed, and then release the dead bolt operating member when the latch bolt 18 is operated again so that the dead bolt 16 protrudes out of the housing. .
