Description

Mortise locking device

The present invention relates to a mortise locking device, in particular, is installed on the outside of the door as the card key is inserted into the dead bolt cam to effectively transmit the rotational force of the dead bolt cam to the dead bolt cam, the card reader and the case The key lever is formed in the card reader so that the coupling is easily performed, and the mortise locking device provided with a key lever connecting means engaged with the key lever in the case.

In general, most door locks have latch operation means for locking and unlocking the door as the latch is released by the rotation mechanism of the rotation means such as a rotary grip installed on the outside and the inside of the door, respectively. .

Also, in order to prevent instability of the door locking by the latch locking means, the dead bolt may be removed by the rotation mechanism of the rotation means such as the rotary knob or the key rotation means such as the card key reader module, separately from the rotation mechanism of the latch. The dead bolt operating means for locking and unlocking the door is installed while being mounted.

Therefore, most door locks are widely used as a mortise locking device having a double locking structure by a latch and a dead bolt.

1 and 2 are some perspective views and configuration diagrams for explaining a conventional mortise locking device for locking and unlocking a door by latch and dead bolt selectively coming out of the case by the latch operating means and the dead bolt operating means. .

As shown, the Mortis locking device is a rotating grip installed and rotated on the case 1 installed inside the door (not shown) and the protection panels 3 and 4 installed inside the case and attached to both sides of the door ( 5 and 6, the latch actuating means for locking and unlocking the door by bringing the latch 17 out of the back plate 2, and a mechanical card reader installed inside the case 1 and installed on the protection panel, respectively. (9) and the rotary knob 15 is made up of dead bolt operating means for protruding the dead bolt 20 to the outside of the back plate 2 to lock and unlock the door.

The latch operating means includes a latch 17 while the first and second latch cams 22 and 23 having the insertion groove 25 into which the drive shafts 7 and 8 of the rotary grip are fitted are rotated by the rotational force applied to the rotary grip. Locks and unlocks the door while coming out of the backplate 2.

That is, when a rotational force is applied to one rotary grip among the rotary grips 5 and 6, the cam link connected to the first or second latch drive cams 22 and 23 in which the driving shaft of the rotary grip to which the rotational force is applied is selectively rotated. Will rotate (26).

When the cam link 26 rotates, the dead bolt link 28 having one end coupled to the cam link 26 and the other end contacting the latch drive shaft 18 moves and pulls the latch drive shaft 18. The latch 17 is moved to the inside of the case 1 to enter the unlocked state.

Then, when the rotational force applied to the rotary grip is lost, the first or second latch cams 22 and 23 rotated are rotated to their original positions as the cam link 26 supported by the return spring 27 is rolled back. The latch 17 is protruded out of the case 1 by the coil spring 19 provided on the latch drive shaft 18 to be locked.

The dead bolt operating means is to allow the locking and unlocking is made while the dead bolt (20) coming out of the case (1) by the mechanical card reader (9) and the rotary knob (15).

First, locking and unlocking are performed by the mechanical card reader 9 while the card reader is rotated in a specific direction (locking or unlocking direction) while a card key (not shown) is inserted into the card reader.

That is, when the card key is inserted into the housing 10 of the card reader, the drive module (not shown) formed in the housing 10 and the cylinder 11 is operated to operate the cylinder cam 12 attached to the end of the cylinder 11. As the cylinder cam rotates, the first and second grooved cam portions 13 and 14 of the cylinder cam selectively engage the first and second protrusion cam portions 30 and 31 of the dead bolt cam 29. .

Therefore, when the dead bolt cam 29 is rotated, the cam portion 32 formed on the opposite end of the protrusion cam portion pushes or pulls the dead bolt drive shaft 21 so that the dead bolt 20 moves out of the back plate 2. Locking and unlocking are performed by letting them go in and out.

The locking and unlocking performed by the rotary knob 15 is similar to the locking and unlocking of the card reader 9 when the rotary knob 15 is rotated. 29) rotates, and the cam portion 32 of the dead bolt cam pushes or pulls the dead bolt drive shaft 21 while the cam portion where the cylinder cam 12 and the dead bolt cam 29 are engaged changes. Locking and unlocking are performed by allowing the 20 to stand out of the backplate 2.

In addition, in the conventional mortise locking device, the dead bolt operating means is interlocked according to the operation of the latch operating means to unlock the dead bolt 20 simultaneously with the operation of the latch operating means.

That is, when the dead bolt 20 protrudes out of the case 1 and is locked, the dead bolt drive shaft 21 moves and the protrusion 33-2 formed on the bottom surface of the dead bolt drive shaft is dead bolt link 28. ) And the projection 33-1 formed on the upper surface of the dead bolt drive shaft pushes one end 34-1 of the fixed link 34 so that the fixed link 34 rotates.

As such, when the fixing link 34 rotates, the fixing piece 36 in which the other end 34-2 of the fixing link moves along the guide hole 35 formed on the bottom surface of the case 1 is recessed in the groove of the second latch cam. Push to insert 24) to prevent the rotating grip (6) installed on the outside of the door to rotate.

At this time, when the rotary grip 5 inside the door rotates, only the first latch cam 22 rotates to move the cam link 26 and the dead bolt link 28, and the dead bolt link 28 is a dead bolt drive shaft. Unlocking of the dead bolt 20 is made by pushing the projection (33-2) formed on the lower surface of (21).

However, such a conventional mortise locking device is not easily coupled to the cylinder cam of the mechanical card reader for operating the dead bolt operating means outside the door and the dead bolt cam of the dead bolt operating means.

That is, the mechanical card reader is provided with a drive module for driving the cylinder cam in accordance with the insertion of the card key or the key is integrally provided in the housing and the inside of the cylinder. The thread formed in the outer periphery of the cylinder of the card reader with the insertion hole formed therein, and then rotating the cylinder of the card reader several times so that the first and second concave cam portions of the cylinder cam and the first and second projection cam portions of the dead bolt cam portion are It must be installed to interlock with each other, but this combination is not easy because it is made inside the case.

In addition, the cylinder with the cylinder cam is not protruded in the center of the housing but eccentrically protruded, so that it is difficult to install the recess of the cylinder cam and the recess of the dead bolt cam.

In addition, there has been a problem in that the size of the housing and the cylinder is increased because the driving module is integrally provided in the housing and the cylinder of the card reader.

Therefore, the present invention is easy to assemble the dead bolt operating means installed in the case and the card reader for operating the dead bolt operating means outside the door is easy to assemble, so that the rotational force of the card reader is efficiently transmitted to the dead bolt cap The purpose is to provide a Mortis locking device.

Therefore, in order to achieve the above object, the mortise locking device according to the present invention rotates the latch cam installed in the case to lock and unlock the latch, and the dead bolt installed inside the case by the rotary knob or the card reader. In the Mortise locking device that the cam is rotated to lock and unlock the dead bolt, one end is located in the card reader and the other end is fixed to the key lever protruding out of the card reader, and the coupling hole perforated on the bottom of the case A plug housing, an insertion hole into which an end of the key lever is inserted, is drilled and a plug inserted into the plug housing and a through hole communicating with the coupling hole are drilled and attached to a lower surface of the plug to form the dead bolt cam.
