 When the opening and closing door system 100 is completely closed, when the opening and closing door 30 is opened, the latching portion 52 of the speed adjusting damper 50 corresponding to the latching jaw 12 starts to move will be.

 This is because when the door 30 is completely closed the engaging portion 52 of the speed adjusting damper 50 is caught by the engaging jaw 12 and the engaging portion 52 is engaged with the engaging portion 57, (58). ≪ / RTI >

When the outermost door 30 is opened, the spring 55 constituting the speed adjusting damper 50 is stretched to increase the elastic force, and the door 30 is strongly opened by the spring 55 It will be opened slowly. As a result, the door is opened to the extent that the door is strongly opened, and a slow opening effect is generated, thereby increasing the stability of the user and adding an elastic force to the speed adjusting damper 50.

When the opening and closing door 30 is continuously opened, the engaging insertion portion 58 constituting the engaging portion 52 is inserted and seated inward in the engaging groove 53 formed in the upward direction, and the elastic spring 55 and the damping The rod 54 is kept in the stretched state, so that an elastic force is added.

5b, if the door 30 is continuously opened, the speed adjusting damper 50 is not caught by the latching jaw 12, and the position of the latching jaw 12 and the position of the speed adjusting damper 50 And the speed adjusting damper 50 fixedly attached to the upper chassis 10 maintains a state of being stretched by the elastic spring 55 and includes an elastic force.

When the opening and closing door 30 is continuously opened, the latching insertion portion 58 is inserted into the latching groove 53 formed in the upward direction, The speed adjusting damper rod 55 is maximally extended, and the speed adjusting damper rod 54, which is connected to the same vertical surface as the engaging portion 52, is kept in the maximum extended state.

When the door 30 is continuously opened in this state, the speed adjusting damper 50 is completely removed from the position of the engaging jaw 12 and the spring 55 of the speed adjusting damper 50 and the speed adjusting damper rod 54 Is kept fixed to the upper chassis 10 while being kept at the maximum stretched state.

5C, when the door 30 is closed again and the attachment position of the speed control damper 50 is reached, the engagement portion 52 is engaged with the elastic spring 55 The door 30 is automatically closed by the increased elastic force so as to buffer the closing speed,

So that when the door 30 is completely closed, the engaging step 12 is retained in the engaging portion 52 of the speed adjusting damper 50; .
