Conventional mortis includes a latch bolt operated by an outdoor or indoor handle, a dead bolt to hold the door locked, and electric or manual driving means for the operation of the dead bolt. Such a mortis can unlock the door by operating the dead bolt using a mechanical key, password, fingerprint, etc., when opening the door outdoors, and then open the door by releasing the latch bolt by operating the outdoor handle. When the door is opened in the room, the door may be opened by releasing the lock by operating the dead bolt with an open switch provided at the indoor side and then releasing the latch bolt by operating the indoor handle.

However, such mortis has a problem that the number of parts and the mechanical configuration are complicated, such as the dead bolt and the latch bolt are separately provided. In addition, when opening the door indoors, it is cumbersome to operate a separate opening switch prior to the operation of the indoor handle, making it difficult to open the door quickly in an emergency situation such as a fire.

The locking device 180 is retracted in a direction orthogonal to the side cover 113 and the locking control bolt 181 to enter and exit the locking control bolt access hole 113b formed in the side cover 113, and the locking control bolt 181. The elastic member 182 (spring) to move in the protruding direction, and the locking bolt (181) is rotatably coupled to the latching bolt (181) when one side is in contact with the inner surface of the side cover 113 when the locking control bolt 181 protrudes. It includes a locking lever 183 that can move toward 120 to hold the latching jaw portion 127 of the latch bolt 120 to maintain the protrusion of the latch bolt 120 in one stage.

As shown in FIG. 9, when the door 1 is opened in a state in which the latch bolt 120 enters the base member 110, the locking control bolt 181 has the threshold 2. ) And protrudes outward from the side cover 113. At this time, since the free end of the locking lever 183 is in contact with the inner surface of the side cover 113, the free end of the locking lever 183 rises toward the latch bolt 120 to be able to be caught by the latching jaw portion 127 of the latch bolt 120. When the user releases the operation of the outdoor handle 20 in this state, the latch bolt 120 is projected to be caught by the latch lever 183 while protruding can be limited to one end. That is, the latch bolt 120 may be held in a state in which the first connecting shaft 125 of the latch bolt 120 is located in the inclined groove 143a so that the latch bolt 120 may be retracted.

When the user closes the door 1 in this state, the latch bolt 120 temporarily retreats while the inclined surface 122a of the latch bolt 120 contacts the threshold 2, and then the latch bolt groove 3 of the door frame 2 is closed. In this case, as shown in FIG. 11, the locking control bolt 181 is pushed by the threshold 2 to enter the base member 110, thereby releasing the latching bolt 181. Accordingly, the latch bolt 120 may protrude more deeply into the latch bolt groove 3 of the door frame 2 so as to maintain a firm lock.

The following describes the opening and closing operation of the door lock employing such mortis.

In the state in which the door 1 is closed, as shown in FIG. 6, the latch bolt 120 maintains a state deeply entered into the latch bolt groove 3 of the door frame 2, and the first latch bolt 120 is closed. Since the connecting shaft 125 is held in the locking groove 143b of the latch lever guide groove 143, the retraction of the latch bolt 120 is limited. Therefore, without a separate dead bolt, a single lock bolt 120 can be maintained a solid lock.

In the state of FIG. 6, when the indoor handle 40 is rotated to open the door 1 indoors, the first rotating member 130 directly connected to the indoor handle 40 rotates, and the first rotating member 130 is rotated. The door 1 may be opened by retracting the latch bolt 120 through the connecting member 142 and the latch lever 141. That is, when the door is opened in the room, the door 1 can be easily opened by simply rotating the indoor handle 40 without any separate operation.

On the other hand, when operating the outdoor handle 20 in the outdoor without the correct access authentication in the state of Figure 6 the clutch device 160 does not operate, the locking pin 161 and the second rotation member 150 is released Maintain state. In this case, despite the rotation of the second rotating member 150 connected to the outdoor handle 20, the first rotating member 130 does not rotate. Therefore, the latch bolt 120 maintains a lock.

In the state of FIG. 6, when the correct access authentication is performed outdoors to open the door 1, as shown in FIG. 7, the driving motor 164 of the clutch device 160 operates to engage the locking pin 161. It operates to be caught by the second rotating member 150. That is, the first rotation cam 163 is rotated by the operation of the driving motor 164, so that the first cam surface 163a of the first rotation cam 163 catches the locking pin 161 of the second rotation member 150. Enter into the groove 151 to be caught. That is, the clutch device 160 operates so that the second rotating member 150 and the first rotating member 130 rotate together.

When the outdoor handle 20 is rotated in the state of FIG. 7, as shown in FIG. 8, the second rotating member 150 and the first rotating member 130 rotate together, and the connecting member (eg, by the first rotating member 130). 142 and the latch lever 141 is operated to retract the latch bolt 120 it is possible to open the door (1).

When the door 1 is opened in the state of FIG. 8, as shown in FIG. 9, the locking control bolt 181 of the locking device 180 protrudes outward from the side cover 113 while being spaced apart from the threshold 2. The latch lever 183 is in contact with the inner surface of the side cover 113 and ascends toward the latch bolt 120 to become a condition where the latch bolt 120 can be caught.

When the user releases the outdoor handle 20 in the state of FIG. 9 (open door), as shown in FIG. 10, the outdoor handle 20 has a restoring force of a spring (not shown) built in the outdoor unit 10. It is restored to its original state by the latch bolt 120 also protrudes at the same time. At this time, the latch bolt 120 is caught by the locking lever 183, the protrusion is limited to one stage, thereby maintaining a state capable of retreating. That is, the first connecting shaft 125 of the latch bolt 120 is positioned in the inclined groove 143a of the latch lever 141 to maintain a retractable state. In this case, the driving motor 164 of the clutch device 160 operates after the predetermined time for restoring the outdoor handle 20 or the first rotation cam 163 rotates to engage the locking pin 161. The locking of the second rotating member 150 may be released.

When the door 1 is closed in the state of FIG. 10, the inclined surface 122a of the latch bolt 120 contacts the threshold 2, and the latch bolt 120 temporarily retreats to close the door 1. When (1) is completely closed, as shown in FIG. 11, the locking control bolt 181 enters the base member 110 while being in contact with the threshold 2. Therefore, the latch bolt 120 is released and the latch bolt 120 further protrudes into the latch bolt groove 3 of the door frame 2. In this case, since the first connecting shaft 125 of the latch bolt 120 is caught by the locking groove 143b of the latch lever 141, the retraction is limited. That is, the initial state (lock state) of FIG. 6 is obtained.

Meanwhile, as shown in FIG. 6, when the door 1 is not opened outdoors due to the discharge of the battery or the failure of the driving motor 164 while the door 1 is locked, the user may open the outdoor unit 10. By using the emergency key module 15 of the emergency unlocking device 170 of the Mortis 100 can be operated. In this case, as shown in FIG. 12, the second rotary link 172 rotates by the rotation of the first rotary link 171, and the rotation of the second rotary link 172 rotates the second rotary cam 169. Let's do it. Accordingly, the second cam surface 169a of the inner surface of the second rotating cam 169 presses the locking pin 161 toward the second rotating member 150 so that the locking pin 161 is the locking groove of the second rotating member 150. 151). When the locking pin 161 is caught by the second rotating member 150 as described above, the door 1 can be opened since the outdoor handle 20 can be manipulated to rotate the first rotating member 130.
