In the accompanying drawings, in order to more clearly express the technical idea of the present invention, parts that are not related to the technical idea of the present invention or can be easily derived from those skilled in the art will be simplified or omitted.

As shown in Figures 1 to 11, the door locking device 10 according to an embodiment of the present invention may be installed on the door to implement the locking of the door.

Furniture, such as a locker, a wardrobe, a drawer, and the like, are provided with an accommodating part that forms a storage space for storing items and a door for selectively opening and closing the storage space.

The door may be moved by an external force at the user's option to close the storage space from the outside or open to the outside.

Here, the door locking device 10 according to an embodiment of the present invention may be a device installed in the door to allow the user to selectively open and close the storage space.

Here, as an example, the door locking device 10 is a rotating part 100 is rotated by an external force about a predetermined axis, the moving part 200 is moved from the locked position to the open position by the rotation of the rotary part 100. And when the external force is not applied to the rotating part 100 may include an elastic part 300 for applying an elastic force to the moving part 200 to move the moving part 200 from the open position to the locked position. have.

For example, when the mobile unit 200 is located at the lock position, the moving unit 200 may be bound to an accommodation unit forming the storage space, thereby limiting the movement of the door based on the accommodation unit.

As a result, the storage space can be closed from the outside, to prevent the loss of the goods to be stored in the storage space.

If the moving part 200 is moved from the locking position to the open position, the moving part 200 is released from being bound to the accommodating part so that the door can be moved relative to the accommodating part. .

As a result, the storage space is opened to the outside, the user can take out the goods stored in the storage space.

For example, the rotating part 100 may be rotated in one direction by an external force acting by the user, and the moving part 200 may rotate the rotating part 100 when the rotating part 100 is rotated in one direction. It can be moved from the locking position to the open position by.

Here, if the user does not apply an external force to the rotating part 100, the elastic part 300 applies an elastic force to the moving part 200 so that the moving part 200 from the open position again the locked position The rotating part 100 may be rotated in another direction by the movement of the moving part 200 to be positioned at its original position.

Here, as an example, the door locking device 10 extends from the support body portion 410 and the support body portion 410 to form a receiving space (S1) for accommodating the rotating part 100 and lock (unused) It may further include a support 400 having a support coupling portion 420 to form a region to which the ()) can be fastened.

In one example, the support body 410 forms the accommodation space (S1), the rotation unit 100 in one direction and / or other relative to the support body 410 on the accommodation space (S1). Direction can be rotated.

In one example, the support portion 420 may extend from the support body 410 to form a space in which the lock can be fastened.

Here, in one example, the rotation unit 100 may be rotated by an external force when the lock is not fastened to the support coupling portion 420 to move the moving unit 200 from the lock position to the open position, When the lock is fastened to the support coupling part 420, even if an external force is applied, rotation may be restricted by the lock, thereby preventing the moving part 200 from moving from the lock position to the open position.

For example, when the lock is fastened to the support part 420, the rotating part 100 is in direct contact with the lock even when an external force is applied, thereby limiting the rotation of the moving part 200 from the locking position. It may not be possible to move it to the open position.

Hereinafter, the configuration of the door locking device 10 will be described in more detail.

For example, the door locking device 10 may further include a linking part 500 which is moved by the rotation of the rotating part 100 to move the moving part 200 from the locking position to the open position. Can be.

For example, the linking unit 500 may be moved by receiving an external force from the rotating unit 100 by moving the position of the rotating unit 100, and transmitting an external force to the moving unit 200 by moving the position. By winning the elastic force of the elastic portion 300 and the moving part 200 can be implemented to move from the locking position to the open position.

For example, as shown in Figure 3, the rotating unit 100 is a rotating body portion 110, which can be gripped to receive an external force, extending from the rotating body portion 110 and the external force to the linking portion 500 It may be provided with a rotating transmission unit 120 and a rotating shaft 130 extending from the rotating body portion 110 to transmit.

Here, as an example, as shown in Figure 4, the support body 410 may form a through space (S2) through which at least a portion of the rotational transmission unit 120 can be inserted and penetrated.

Here, for example, the rotation transmission unit 120 may be moved in the first direction when an external force is applied, the linking unit 500 is to move in the first direction of the rotation transmission unit 120. By receiving the external force from the rotation transmission unit 120 may be moved in the first direction.

Here, for example, the moving part 200 receives an external force from the linking part 500 by the movement of the linking part 500 in the first direction, and is a second direction different from the first direction. Position can be moved.

For example, the first direction may mean an upper direction, and the second direction may mean a left or right direction.

If the rotation body 110 is rotated in one direction by an external force, the rotation transmission unit 120 may be moved in an upward direction by the rotation of the rotation body 110.

When the rotational transmission unit 120 is moved upward, the linkage unit 500 may be moved upward by the rotational transmission unit 120 while being mounted on the rotational transmission unit 120. Can be.

Here, as an example, as shown in FIG. 5, the linking part 500 may be formed as a surface inclined in contact with the moving part 200.

As shown in FIG. 6, the moving part 200 has an inclined surface corresponding to the inclined surface of the linking part 500 and an insertion space S4 into which the linking part 500 can be inserted. The mobile body unit 210 and the elastic unit 300 to form a movement may be provided with a binding unit 220 that can be bound.

That is, as shown in FIG. 9, when the rotational transmission part 120 penetrating the through space S2 is moved upward, the linkage part 500 is moved upward, and the moving part ( The 200 may not slide in the upward direction by the inclined surface corresponding to the inclined surface of the linking part 500, but may slide in the left or right direction.

As a result, the moving part 200 can be moved from the locking position to the open position.

Here, as an example, as shown in Figure 4, the support portion 400 is extended from the support body portion 410 so that the linkage portion 500 is moved in the first direction of the linkage portion 500 A support guide part 430 may be further provided to guide the movement.

5, the linkage part 500 may form a linkage groove S3 corresponding to the support guide part 430.

That is, as shown in Figure 11, the support guide portion 430 is inserted into the linkage groove (S3) when the linkage portion 500 is moved in the upper direction, it is moved in a direction other than the upper direction Can be restricted.

In addition, as an example, as shown in FIGS. 4 and 11, the support part 400 may reduce friction with the support body part 410 when the moving part 200 is moved in the second direction. Protruding from the support body 410 may further include a support friction portion 440 in contact with the moving part 200.

For example, if the moving part 200 is moved from the locking position to the open position and / or from the opening position to the locking position with respect to the support body portion 410, the support body portion ( If the area rubbed with the 410 is large, the durability of the moving part 200 and the support body 410 may be weakened.

In order to solve this problem, the support friction part 440 protrudes from the support body part 410 in the direction of the moving part 200 to be in contact with the moving part 200. The area rubbed with the support body 410 can be reduced.

In addition, as an example, as shown in Figures 1, 2 and 7, the door locking device 10 is a first arrangement space in which the moving part 200 and the elastic part 300 can be disposed An inner cover part 600 may be further formed to form a second placement space S6 in which S5 and the linking part 500 may be disposed.

For example, the inner cover part 600 may cooperate with the support part 400 to cover at least a portion of the moving part 200, the elastic part 300, and the linking part 500.

For example, the inner cover part 600 extends from the inner cover body part 610 and the inner cover body part 610, which form the first placement space S5 and the second placement space S6. An inner detachment preventing part 620 may be provided to prevent the elastic part 300 from being separated from the first arrangement space S5.

That is, the moving part 200 and the elastic part 300 are disposed in the first placement space S5 so that the moving part 200 and the elastic part 300 are disposed by the inner cover body part 610 and / or the inner departure preventing part 620. Departure from the one arrangement space S5 can be prevented.

For example, one end of the elastic part 300 is bound to the inner departure preventing part 620 and the other end is bound to the moving binding part 220 so that the moving part is not separated from the first placement space S5. An elastic force may be applied to the 200.

In addition, as an example, the inner cover part 600 may include a first exposure space such that at least a portion of the moving part 200 and the elastic part 300 disposed in the first placement space S5 are exposed to the outside. S7) may be formed, and a second exposure space S8 may be formed such that at least a portion of the linkage part 500 disposed in the second placement space S6 is exposed to the outside.

For example, the inner cover body 610 may form the first exposure space S7 and the second exposure space S8.

If at least one of the moving part 200, the elastic part 300, and the linking part 500 disposed in the first placement space S5 and the second placement space S6 is damaged, the user may be damaged. As intended, when the moving unit 200 and the linking unit 500 are not moved, the user directly moves the moving unit 200 through the first exposure space S7 and the second exposure space S8. And the external force is applied to the linking unit 500 to move the moving unit 200 to the lock position or the open position.

1, 2 and 8, the door locking device 10 is that the rotating part 100 disposed in the accommodation space (S1) is separated from the accommodation space (S1). It may further include an outer cover portion 700 to prevent.

For example, the outer cover part 700 extends from the outer cover body part 710 and the outer cover body part 710 connected to the support part 400, and covers at least a part of the rotation shaft 130. The cover unit 720 may be provided.

Here, as shown in FIG. 4, for example, the support part 400 may further include a support cover part 450 extending from the support body part 410 and covering at least a portion of the rotation shaft 130. Can be.

That is, the rotation shaft 130 is inserted into a space formed by the rotation cover portion 720 and the support cover portion 450 to external force based on the rotation cover portion 720 and the support cover portion 450. Can be rotated by
