1 to 5, the door lock device according to the present embodiment is also configured to include a mortise having a clasp for locking and releasing the door, and an indoor side and an outdoor side installed on the indoor side and the outdoor side of the door, respectively. The point is no different from the conventional door lock device.

On the other hand, the door lock device according to the present embodiment is conventional in that the user is provided with an interior handle unit configured to selectively clutch the interior handle and the clasp, or the interior handle and the clasp can always rotate together. It is different from the door lock device.

That is, the indoor handle unit of the present embodiment includes a handle housing 10, a clutch member 20, a fixing member 40, and a button member 50.

The handle housing 10 is rotatably coupled to the interior side of the door. The handle housing 10 includes a cylinder portion 11, a handle portion 12 formed long in one direction and connected to the cylinder portion 11, and a cover portion 13 coupled to the handle portion 12.

The cylinder portion 11 has a space in which the clutch member 20 and the elastic member 30 are installed. The cylinder portion 11 is open to both sides. In addition, a pair of grooves 111 facing each other are formed concave on the inner surface of the cylinder portion 11. In addition, the handle part 12 and the cover part 13 are portions that the user grasps and rotates the handle housing 10. In addition, the insertion hole 131 is formed through the cover portion 13.

The clutch member 20 is formed in a cylindrical shape as a whole. One side of the clutch member 20 is formed with an insertion hole 211 into which the shaft 25 is inserted. Insertion hole 211 is formed in a rectangular shape. Shaft 25 is formed long in the thickness direction of the door, the end portion of the shaft 25 to be inserted into the insertion hole 211 is formed in a rectangular shape to engage the insertion hole (211). The shaft 25 is disposed to protrude to one side of the cylinder portion 11. The shaft 25 rotates together with the clutch member 20, and is connected to the clamp so that a clamp (not shown) operates when the shaft 25 is rotated. Since the interlocking structure of the shaft and the clasp corresponds to a well-known structure as already described in the related art, a detailed description thereof will be omitted herein. In addition, the elastic member 30 is inserted into the insertion hole 211. In this embodiment, the elastic member 30 is composed of a compression coil spring, both ends of the compression coil spring are in contact with the inner surface of the insertion hole 211 and the shaft 25, respectively.

The clutch member 20 includes a cylindrical body portion 21 having an insertion hole 211, a projection 22 of one phase protruding from the outer circumferential surface of the body portion 21 so as to face in a direction opposite to each other in the radial direction, And a pressurized portion 23 protruding from the surface of the body portion in the longitudinal direction of the body portion 21. Insertion hole 211 is formed on one side of the body portion 21, the pressurized portion 23 is formed on the other side of the body portion (21). In addition, the pair of protrusions 22 is formed in an arc shape, the shape of which corresponds to the shape of the groove 111 of the cylinder portion 11 and the size thereof is substantially the same.

The clutch member 20 is selectively rotatably inserted into the cylinder portion 11 of the handle housing. That is, the clutch member 20 rotates relative to the handle housing 10 in the interlock release position shown in FIG. 3, and rotates together with the handle housing 10 in the interlock position shown in FIG. 4. In addition, the clutch member 20 is inserted into the cylinder portion 11 of the handle housing so as to be linearly movable between the disengaged position and the interlocked position.

When the clutch member 20 is disposed at the disengaged position shown in Fig. 3, each of the protrusions 22 of the clutch member is separated from each groove 111 of the handle housing. Therefore, even when the handle housing 10 is rotated, each protrusion 22 does not press the inner surface of each groove 111, and thus the clutch member 20 does not rotate. As such, if the clutch member 20 does not rotate, the shaft 25 also does not rotate, and the clamp does not operate.

On the other hand, when the clutch member 20 is disposed in the interlocking position shown in Fig. 4, each projection 22 of the clutch member is inserted into each groove 111 of the handle housing. Therefore, when the handle housing 10 is rotated, each protrusion 22 presses the inner surface of each groove 111 so that the clutch member 20 also rotates together with the handle housing 10. When the shaft 25 also rotates together with the clutch member 20 as described above, the lock is operated so that the door can be unlocked by the rotation of the handle housing.

The clutch member 20 is elastically biased toward the interlock release position by the elastic member 30. The elastic force of the elastic member 30 always acts in the direction in which the protrusion 22 of the clutch member 20 is separated from the groove 111 of the handle housing.

The fixing member 40 is fixed to the handle housing 10, and does not have a relative linear movement as well as a relative rotational movement with respect to the handle housing. Accordingly, when the handle housing 10 is rotated, the fixing member 40 rotates together in the same direction as the handle housing 10. A pair of insertion holes 411 through which the pressurized portion 23 of the clutch member is inserted is formed in the flat plate portion 41 of the fixing member. In addition, the pair of hook portions 42 protrude from the other side surface of the flat plate portion 41, that is, the surface not facing the clutch member 20. Each hook portion 42 includes a connection portion 421 connected to the other side of the flat plate portion 41 and an extension portion 422 extending upward from an end portion of the connection portion.

The button member 50 includes a flat plate portion 51 disposed between the cover portion 13 and the handle portion 12 and a button portion 52 inserted into the insertion hole 131 of the cover portion. Grooves 511 are recessed on both sides of the flat plate 51.

The button member 50 is capable of reciprocating linear movement in the first direction and the direction opposite to the first direction. Here, the first direction refers to a thickness direction of the door, particularly a direction approaching the interior side of the door. When the button member 50 is pressed in the first direction, the flat plate portion 51 of the button member presses the pressurized portion 23 of the clutch member, so that the clutch member 20 is disposed in the interlocked position. At this time, since the hook portion 42 of the fixing member is disposed inside the groove portion 511 of the flat plate portion and does not contact the flat plate portion 51, there is no restriction on the movement of the button member 50 to the interlocking position. In this way, when the clutch member 20 is located in the interlocking position, holding the handle portion 12 of the handle housing and rotating the handle housing 10, the clutch member 20 together with the handle housing 10 also rotates together. do. Therefore, the shaft 25 connected to the clutch member 20 also rotates together.

On the other hand, the button member 50, when the button member 50 is pressed, that is, the button member 50 is pressed as shown in Fig. 5 (a), the clutch member 20 is placed in the interlocking position In reciprocating linear movement in the second direction and the opposite direction of the second direction is possible. Here, the second direction is a direction intersecting with the first direction, and particularly means downward. Even if the button member 50 moves linearly in the second direction, the flat plate portion 51 of the button member continues to be in contact with the pressurized portion 33 of the second clutch member, so that the second clutch member 30 ) Continues to be in the interlocking position. In addition, when the button member 50 is linearly moved in the second direction, a portion of the flat plate 51 of the button member is fitted to the hook portion 42 of the fixing member, as shown in FIG. Even if the user does not press the button portion 51 of the button member, the button member 50 does not retreat by the elastic force of the elastic member 30. That is, the upper portion of the groove portion 511 of the flat plate portion 51 of the button member, that is, the locking portion 512 is a groove portion between the extension portion 422 of the hook portion 42 and the flat portion 41 of the fixing member ( Since it is fitted to the 423, even if the elastic force of the elastic member 30 is applied, the button member 50 is caught by the extension portion 422 of the hook portion does not retreat, thereby pressing the clutch member 20 also continues Retained, the clutch member 20 is continuously arranged in the interlocking position.

In the door lock device configured as described above, even if the handle housing 10 is rotated in the state in which the button member 50 is not pressed, the clamp cannot be operated. When the handle housing 10 is rotated after pressing the button member 50 in the first direction and placing the button member 50 in the interlocked position, the clutch member 20 also rotates together with the handle housing 10, thereby eventually clutching the member 20. By rotating the shaft 25 coupled to the) it is possible to operate the clamp. In addition, in the case of selecting an anti-panic mode capable of operating the clamp by simply rotating the handle housing 10, the button member 50 is pushed in the first direction to be placed in an interlocking position, and then the button member 50 is pushed. The locking portion 512 of the button member may be inserted into the groove portion 423 formed by the hook portion 42 of the fixing member by linearly moving in the second direction.

As described above, in the door lock device of the present embodiment, the user can selectively implement the anti panic function, so that the vulnerability of the door lock device having the conventional anti panic function is implemented, that is, hacking using a wire or the like after forming a hole in the door can be effectively performed. You can block. Therefore, the security of the door lock device is improved.

As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the technical idea of the present invention. It is obvious.
