The pressing protrusion 133 may protrude toward the locking device 134 and may include an inclined surface 133a corresponding to the inclined portion 136 of the locking device 134. When the lever 131 is raised, the pressing protrusion 133 may press the locking device 134 to rotate the locking portion 135 of the locking device 134 to be inserted into the door rail 104.

The locking device 134 may be rotatably coupled to the fixing member 137. The fixing member 137 may be fixed to the plate body 111. The locking device 134 may include a locking part 135 provided to be inserted into the door rail 104 as it rotates with respect to the fixing member 137. The locking part 135 may be disposed at the other end opposite to one end rotatably coupled to the fixing member 137 of the locking device 134.

The locking device 134 may receive torque in a direction in which the locking portion 135 is separated from the door rail 104 by the torque member 138. The torque member 138 may be provided with a spring. The torque member 138 may have one end fixed to the locking device 134 and the other end fixed to the fixing member 137.

Referring to FIG. 9, when the door plate 110 is in the first position, the lever 131 of the locking device 130 is in an elevated state, and accordingly, the pressing protrusion 133 of the locking device 134 By pressing the inclined portion 136, the locking portion 135 may be inserted into the door rail 104 of the first door 101. As the locking part 135 is inserted into the door rail 104, the door plate 110 is fixed to the first door 101, and thus, the door plate 110 is positioned at the first position by its own weight. It can prevent it from being moved to the position.

Referring to FIG. 10, when moving the door plate 110 to the second position, the user may lower the lever 131 by pressing the switch 132 of the lever 131 downward. As the lever 131 descends, the pressing protrusion 133 that presses the inclined portion 136 of the locking device 134 slides down along the inclined portion 136 and does not press the locking device 134. Accordingly, the locking device 134 is rotated in a clockwise direction by the torque member 138, and the locking part 135 is released from the door rail 104 of the first door 101. When the door plate 110 is released from the first door 101 in this way, when a user applies a predetermined force in the direction of moving the door plate 110 from the first position to the second position, the door plate 110 Is moved from the first position to the second position by its own weight.

Thereafter, when the user wants to move the door plate 110 back to the first position and fix it to the first door 101, the user raises the switch 132 of the lever 131 so that the locking part 135 The locking device 134 may be rotated to be inserted into the rail 104.

Referring to FIG. 11, the door device 100 may include a damper device 140 and a lift device 145.

The damper device 140 may be provided to prevent rapid movement when the door plate 110 moves from the first position to the second position.

The damper device 140 may include a first damper part 141 and a second damper part 142 provided to be slidable on the first damper part 141. The second damper part 142 is provided to be inserted into the first damper part 141, and a material with strong viscosity such as oil may be provided between the first damper part 141 and the second damper part 142. Accordingly, the second damper part 142 may be configured so that it cannot be rapidly moved with respect to the first damper part 141.

The first damper part 141 may be fixed to the first damper fixing part 143 disposed on the door bar 116, and the second damper part 142 is a second damper high disposed on the sliding plate 113. It can be fixed to the government 144.

When the door plate 110 moves from the first position to the second position, the sliding plate 113 descends along the door rail 104 of the first door 101. The door bar 116 is rotatably coupled to the bar connecting portion 117 of the sliding plate 113. The rotation axis of the door bar 116 with respect to the sliding plate 113 is provided to be different from the rotation axis of the plate body 111 with respect to the sliding plate 113.

When the sliding plate 113 descends, the door bar 116 rotates with respect to the sliding plate 113. As the position of the rotation axis of the door bar 116 with respect to the sliding plate 113 and the position at which the first damper fixing part 143 is fixed to the sliding plate 113 are different, the door bar 116 is the sliding plate 113 ), the distance between the first damper fixing part 143 fixed to the door bar 116 and the second damper fixing part 144 fixed to the sliding plate 113 decreases. Accordingly, a part of the second damper part 142 is inserted into a part of the first damper part 141, and at this time, the damper device 140 is provided to prevent rapid movement. The damper part 142 is gradually inserted into the first damper part 141, and thus, the door plate 110 can gradually move to the second position. In FIG. 6, two damper devices 140 are shown, but one or three or more damper devices 140 may be provided.

The lift device 145 may be provided to support the movement of the door plate 110 when the door plate 110 moves from the second position to the first position. The lift device 145 allows the user to move the door plate 110 from the second position to the first position with a relatively small force.

The lift device 145 may include a first lift unit 146 and a second lift unit 147 provided to be slidable on the first lift unit 147. The second lift part 147 may be provided to be inserted into the first lift part 146.
