The case where the bundle 233 and the bundle 232 of the switch is located at the upper end of the bundle induction part is a starting point. The user is diffracted by the hinge coupler 320 of the fixing device 300 with respect to the locking device 200 so that the bundle 233 is inserted into the fixing groove 331.

In this case, users located inside and outside the door cannot open the door.

Since the user inside the door when pressing the switch control unit 234 from the top to the bottom of the bundle 233 of the switch is inserted into the interior of the second bunching induction part 332 in the state inserted into the fixing groove 331 Moving to the state and also the bundle column 232 is passed through the left and right leaf spring 225 interpolated in the switch box 220 to move along the first bundle column guide portion 221 and the second bundle column guide portion 332. do.

When the bunching column 232 descends from the stop point of the first bunching induction part 221 and the second bunching induction part 332, that is, the movement start point, the user inside and outside the door can open the door. Becomes

When the door is opened, the bundle 233 changes the direction of movement in the state of being inserted into the second bundle induction part 332 of the fixing device 300 so that the bundle 233 can continuously move in the state of being inserted into the moving part 340 again. If the bundle 233 is moved to the end of the moving portion 340 is that the door is no longer opened.

In addition, as shown in Figures 7 to 8, the swing door locking device of another embodiment is the same as the operation method described above, but allows the rotation angle of the locking portion 330 can be rotated in stages.

That is, the locking unit of the locking device according to the degree of opening the door when the locking function by performing the locking function by clamping the bundle 233 of the locking device 200 to the moving part 340 of the fixing device 300 (310) Will rotate).

At this time, the locking groove 321 formed on the outer circumferential surface of the hinge coupling portion 320 of the locking portion 330 is in close contact with the ball 323 supported by the elastic force of the spring 322 to rotate the locking portion 330 Each time the angle of the lock proceeds step by step.

In addition, as shown in Figures 9a to 10b, the operation of another embodiment of the present invention is performed as follows.

First, when the door is intermittent, the bundle 233 of the locking device 200 is fitted into the fixing groove 331 of the fixing device 300 in a state where the door is closed on the door frame.

At this time. The bundle 233 is rotated by 90 ° in the bundle column 232 so that the long side of the vertical or horizontal length is located in the vertical direction, the bundle 233 is coupled to the fixing groove 331 of the locking portion 330 After the exposure to the rear side and then back to rotate the bundle 233 at an angle of 90 ° to ensure that the bundle 233 in the fixing groove 331.

In addition, when partially opening the swing door, while the locking portion 330 of the fixing device 300 is partially rotated to enable the partial opening of the swing door, the agglomeration column 232 by the rotation angle of the fixing device 300. The sliding is moved to the moving part 340 of the fixing device 300.

Then, when opening the door in the door frame to close the door to the door frame lock 330 is rotated so that the bundle 233 of the locking device 200 is located in the fixing groove 331 of the fixing device 300 The bundle 233 is reversely rotated at an angle of 90 ° so that the bundle 233 is separated from the fixing groove 331.
