Description

Motor-Driven Mortise Locking Device by Using Bevel Gear}

The present invention relates to a mortise lock device applied to the door lock. More specifically, the drive motor for driving the dead bolt of the electric mortis using the bevel gear and the magnetic sensor for the automatic locking of the door lock are mounted inside the mortis, and the operation of the dead bolt and the latch bolt is separately performed through a relatively simple mechanical configuration. The present invention relates to an electric mortise lock device applied to a digital door lock which simplifies the structure of the mortise.

In general, the door lock is widely used in the front door of a general house, the entrance door of apartments, businesses, offices, etc., or the safe of a bank. Such door locks generally include an outer operation part installed on the outside of the door, an inner operation part installed on the inside of the door, and a mortise locking device installed in the door, and the mortise locking device installed in the door generally includes dead bolts and latch bolts. It has a structure in which the coupling groove is formed up and down in the door frame is installed up and down and the corresponding position.

Here, the dead bolt is man-made when the projecting part is rectangular in cross section and is opened and closed.In the case of the latch bolt, the part inserted into the coupling groove formed in the door frame forms an inclined surface or forms a gentle curved surface. When opening, the handle is turned to operate, but when the door is closed, the inclined surface of the latch bolt is pushed into the door frame to close the door.

In the case of the conventional mechanical door lock mortise lock device as shown in Figure 1a, the configuration is very complicated and there is an excessive cost to manufacture, and the operation between parts is unstable, so long-term use, such as breakage of one part Due to the problem that the lock does not function properly.

On the other hand, in the case of the conventional electronic door lock as shown in Figure 1b, the driving of the dead bolt is indirectly by the action of the motor (1), the mechanical assembly and the rotating shaft, etc. mounted on the inner or outer body of the door. First, it is difficult to diversify the design of the door lock when developing the electronic door lock. Second, the installation of the electronic door lock is not easy because the drive shaft related to the driving of the dead bolt must be mounted. Third, the construction of the electronic door lock. If the door to be constructed is bent, the drive shaft associated with the driving of the dead bolt, etc. did not work properly, there was a problem such as poor construction.

On the other hand, in the case of the conventional electronic door lock, such as the magnetic sensor (2) for automatic locking of the electronic door lock protrudes to the outside of the inner operating portion of the door, there is a problem that the perforation hole of the door is increased and its shape is messy.

Therefore, the present invention is designed to solve this problem, and the drive motor 16 for driving the dead bolt 13 and the magnetic sensor 28 for the automatic locking of the door lock inside the mortis 10 and relatively simple By making the operation of the dead bolt 13 and the latch bolt 17 separately through a mechanical configuration, it is possible to vary the design of the door lock during the development of the digital door lock, and the dead bolt after the construction of the door lock regardless of the door condition An object of the present invention is to provide a motorized mortise lock device applied to a digital door lock that eliminates a malfunction of the door lock and is easy to install.

4A and 4B, the interlocking state of the dead bolt 13 by the dead bolt driving means will be described in detail.

First, when the dead bolt drive motor 16 is operated by an electric signal while the dead bolt 13 is completely protruded out of the mortis 10, the lever dead bolt bevel engaged with the drive bevel gear 16a is rotated. The lever dead bolt 15 which is integral with the gear 15a is interlocked and rotated counterclockwise.

At this time, the lever dead bolt arm 15b also rotates in the counterclockwise direction, while acting on the dead bolt bracket 14 connected to the dead bolt 13 to draw the dead bolt 13 into the mortise 10 and the other. On the other hand, it acts on the lever sensor first arm 21a to rotate the lever sensor 21 counterclockwise. FIG. 4A shows a state immediately before the dead bolt 13 is completely inserted into the mortise 10. It is shown.

On the other hand, the photosensor 27 mounted on the electronic control circuit 26 detects the position of the light shielding piece 22 of the lever sensor 21 to stop the drive motor 16, so that the dead bolt 13 is the mortise (10) ) To stop in the fully inserted state.

Next, as shown in FIG. 3, in the state where the dead bolt 13 is completely drawn into the mortis 10, the driving motor 16 introduces the dead bolt 13 again by an electrical signal. When actuated, the driving bevel gear 16a rotates in reverse and rotates the lever dead bolt 15 clockwise.

At this time, the lever dead bolt arm 15b also rotates in the clockwise direction and acts on the dead bolt bracket 14 connected to the dead bolt 13 to protrude the dead bolt 13 to the outside of the mortise 10. FIG. The state in which the bolt 13 immediately before fully protrudes out of the mortis 10 is shown.

On the other hand, when the force applied to the lever sensor first arm 21a disappears while the lever dead bolt arm 15b rotates clockwise, the lever sensor 21 also rotates clockwise by the restoring force of the sensor spring 23. .

The drive motor 16 is stopped.

Referring to Figure 6 will be described in detail the interlocking state of the latch bolt 17 by the latch bolt interlocking means.

First, when the pivot lever latch 20 connected to the handle and the shaft rotates in the clockwise direction by the rotation of the handle, the pivot lever latch 20a acts on the bracket latch 19 to perform the linear movement of the bracket latch 19. By pulling out, the latch bolt 17 is drawn into the mortise 10. FIG. 6 illustrates a state immediately before the latch bolt 17 is completely drawn into the mortise 10.

Next, when an external force is removed from the handle connected to the pivot lever latch 20 and the shaft while the latch bolt 17 is fully inserted into the mortise 10, the latch bolt 17 may be restrained by the restoring force of the compressed latch spring 18. 17 protrudes out of the mortise 10.

Meanwhile, when the door 200 is closed, the door 200 is automatically sensed to operate the driving motor 16 to automatically lock the door 200 by protruding the dead bolt 13 to the outside of the mortise 10 through the dead bolt driving means. The magnetic sensor 28 is installed inside the mortis 10 as shown in FIG. When the door 200 is closed, the magnetic sensor 28 detects the relative magnet 28a installed in the door frame, and when the predetermined time (for example, 10 seconds) elapses from this, the driving motor 16 is operated to dead. The dead bolt 13 protrudes out of the mortise 10 through the bolt driving means to automatically lock the door 200.

7 is a cross-sectional view showing a digital door lock device having a mortise lock device applied to the digital door lock according to the present invention installed in the door 200. The outer operation part 100 installed outside the door 200 is provided with an unlocking means 102 for opening the door 200 and an outer handle 101 connected to the pivot lever latch 20 by a shaft. The inner operation part 110 installed inside the door 200 is provided with an inner handle 111 connected to the pivot lever latch 20 by the battery part 112 and the shaft.
