The latch bolt 30 is for preventing the door 1 from being arbitrarily opened by a light shock or wind, and when the latch bolt 30 is inserted into the latch bolt insertion hole 4 formed in the door post 2, the door 1 is prevented from being opened arbitrarily. do. The latch bolt 30 includes a latch member 31 and a moving member 32.

The latch member 31 is inserted into the latch bolt access hole 122, and wanders through the latch bolt access hole 122 to be inserted into or removed from the latch bolt insertion hole 4. The front end portion 311 of the latch member is formed with an inclined surface or a curved surface inclined with respect to the direction in which the latch member 31 is projected, that is, the direction protruding and immersed with respect to the front plate 12. Therefore, when the door 1 is opened and closed, the front end portion 311 of the latch member is pressed by the door holder 2 and moves in the direction immersed with respect to the front plate 12.

In addition, the insertion groove 312 is formed at the rear end of the latch member 31 to open to the rear of the latch member 31, respectively. And, the insertion groove 312 is formed to open in the vertical direction. The insertion groove is formed to have a T shape as a whole when projecting on a cross section perpendicular to the vertical direction. The protrusions 313 are protruded from both side surfaces of the latch member 31, that is, the side surfaces facing the thickness direction of the door 1.

Each insertion protrusion 321 is formed to correspond to the shape of the insertion groove portion 312 of the latch member and to have substantially the same size.

The moving member 32 and the latch member 31 are coupled and separated as a pair of insertion protrusions 321 are inserted into and separated from the pair of insertion grooves 312. That is, as shown in FIG. 4, when a pair of insertion protrusions 321 are respectively inserted into the pair of insertion grooves 312, the movable member 32 and the latch member 31 are coupled to each other to form a body. It will move straight. In this state, since the protrusion 313 of the latch member is blocked by the front plate 12 as shown by a dotted line in FIG. 7, the latch member may be pulled away from the front plate 12 even when the latch member 31 is separated from the front plate 12. (31) cannot be separated. In addition, when the latch member 31 is moved upward in the state shown in FIG. 4, the insertion protrusions 321 are separated from the insertion grooves 312 as shown in FIG. 6, and the latch bolt 30 is further removed. As shown in FIG. 7, the first and second parts 122a and 122b of the latch bolt access hole 122 of the front plate may be sunk. That is, the protrusion 313 of the latch member may be sunk through the second portion 122b and the remaining portion of the latch member 31 through the first portion 122a. Therefore, when the direction of the latch bolt 30 is changed, the latch member 31 may be removed from the housing 10 in the state of FIG. 6, and then the direction may be changed and inserted again through the latch bolt access hole 122. Of course, in order to change from the state shown in FIG. 4 to the state shown in FIG. 6, the blocking member 50, which will be described later, must first be separated from the front plate 12.

In addition, the coupling direction for coupling the latch member 31 to the movable member 32 and the separation direction for separating the latch member 31 from the movable member 32 are downward and upward, respectively, and the coupling direction and separation direction are respectively. The latch member 31 is perpendicular to the linear movement direction. In addition, in the state where the latch member 31 and the movable member 32 are coupled, each of the insertion protrusions 321 is in contact with the inner surface of each of the insertion grooves 312, so that the latch member 31 and the movable member 32 Is a linear movement into one body.

The elastic member 40 is installed in an installation space between the case 11 and the cover 13. The elastic member 40 is composed of a compression coil spring, and elastically biases the latch bolt 30 in a direction protruding with respect to the housing 10.

The blocking member 50 is bolted to the front plate 12 of the housing. The blocking member 50 includes a front portion 51 and an insertion portion 52.

The front portion 51 is formed in a plate shape, the front bolt 51 is connected to the dead bolt access hole 121, the dead bolt connecting hole 511 and the latch bolt access hole 122 is connected to the latch bolt connection hole 512 are each formed through. The dead bolt connection hole 511 is a passage through which the dead bolt 20 enters and out, and the latch bolt connection hole 512 is a passage through which the latch member 31 enters and exits. However, when the latch member 31 is coupled to the movable member 32 as shown in FIG. 4, the front end portion 311 of the latch member 31 enters and exits the latch bolt connecting hole 512.

Insertion portion 52 is formed extending in the direction orthogonal to the front portion 51, it is preferable to be formed by bending a portion of the front portion (51). The insertion part 52 is inserted into the latch bolt access hole 122, in particular, the latch bolt access hole 122 when the blocking member 50 is coupled to the front plate 12, and the latch member 31 is inserted into the inserting part 52. The movement of the latch member 31 is prevented by contacting the latch member 31 during the linear movement upwardly, i.e., upward from the moving member 32. As shown in FIG. That is, in the state in which the blocking member 50 is coupled as shown in Figure 4, the insertion member 52 of the blocking member prevents the upward movement of the latch member 31, the latch member 31 is a moving member Separation from 32 is prevented.

On the other hand, in the state in which the latch bolt 30 is coupled to operate as shown in Figure 4, the gap (gap) between the latch bolt 30 and the inner surface of the housing 10, the latch bolt 30 and the latch bolt. The gap between the access hole 122 and the gap between the latch bolt 30 and the latch bolt connecting hole 512 is formed smaller. That is, the gap between the protrusion 313 of the latch member and the inner surface of the case 11 and the gap between the protrusion 313 of the latch member and the inner surface of the cover 13 are inserted into the front end portion 311 of the latch member 31 and the latch bolt. The gap between the inner surface of the ball 122 and the gap between the latch member 31 front end portion 311 and the inner surface of the latch bolt connecting hole 512 is smaller than.

In the door lock device 100 configured as described above, the latch member 31 cannot be rotated in a desired direction in the installed state as shown in FIG. 4, but the latch member 31 is subjected to the following process. By rotating, the installation direction of the latch member 31 can be easily changed according to the opening direction of the door 1.

First, when the blocking member 50 shown in FIG. 4 is removed from the front plate 12, and the front end portion 311 of the latch member is grabbed and pushed upwards, the insertion groove 312 of the latch member as shown in FIG. It is possible to separate the insertion projection 321 of the moving member from. Then, the latch member 31 is pulled away from the front plate 12 to completely separate the latch member 31 from the housing 10, and then the latch member 31 is rotated so that the front end portion 311 of the latch member is different from the previous one. Face in the opposite direction. Thereafter, the latch member 31 is inserted through the latch member access hole 122 of the front plate, and then moved downward so that the insertion protrusion 321 of the movable member is inserted into the insertion groove 312 of the latch member. After changing the direction in which the front end portion 311 of the latch member faces in this manner, the insertion portion 52 of the blocking member is inserted into the latch bolt access hole 122 and the blocking member 50 is bolted to the front plate 12. Then, the installation direction change of the latch bolt 30 is completed.

As such, in the present embodiment, the assembly process is more simply performed because the process of additionally combining the bolts is not required for the rotation setting of the latch bolt 30. Furthermore, the latch bolt 30 modification structure is simpler than in the related art, thereby improving durability. In addition, even if the conventional bolt is omitted, there is an advantage that the door lock device is easily configured by simply modifying the conventional components without any additional components.

In the present embodiment, the gap between the protrusion 313 of the latch member and the inner surface of the case 11 and the gap between the protrusion 313 of the latch member and the inner surface of the cover 13 are inserted into the latch member 31 and the latch bolt. Since the gap between the inner surface of the ball 122 and the gap between the latch member 31 and the inner surface of the latch bolt connecting hole 512 is smaller than, the operation of the latch member can be made more smoothly. This is because the latch member contacts the inner surface of the housing 10 without sliding the latch bolt access hole 122 and the latch bolt connecting hole 512 in the operation process and performs the sliding motion.

On the other hand, in the present embodiment, the latch member and the moving member in the coupled state as shown in Figure 4, even if the blocking member is not engaged in the direction in which the latch member is protruding to the housing, but the latch bolt access hole of the front plate When the latch member is formed to include the protrusion of the latch member, the latch member protrudes from the front plate by the elastic force of the elastic member. However, even in this configuration, it is possible to solve the problem of protruding the latch member only by forming the latch bolt connecting hole to an appropriate size so that the blocking member can block the protrusion of the latch member.

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.

For example, in the present embodiment, although the insertion groove and the insertion protrusion are formed in the latch member and the moving member, respectively, the insertion protrusion and the insertion groove may be formed in the latch member and the moving member, respectively.

In addition, in the present embodiment, the protrusion is configured to be formed on the latch member, but the protrusion may be configured to be formed on the movable member. Of course, even in this case, the protrusion is blocked by the front plate to prevent the latch bolt from being separated in the direction in which it protrudes with respect to the housing.
