&Lt; Operation relationship of the door opening / closing device >

FIG. 6 is a projection plan view of a door closing mode according to an embodiment of the present invention, FIG. 7 is a projection plan view of a first door opening mode according to an embodiment of the present invention, and FIG. 2 is a projection plan view of the two-door open mode. As shown in FIGS. 6, 7 and 8, the door closing mode, the first door opening mode, and the second door opening mode can be classified according to the position of the drive shaft.

The door closing mode means that the latch 7 protrudes outward from the door 3 and the external force does not act on the driving shaft 10. The driving shaft 10 does not move in the longitudinal direction when there is no external force and the center of the guide rail 12 is positioned at the center of the door opening / closing apparatus 1 by the house spring 20. The latch drive portion 30 is pulled by the latch spring 36 and the bearing portion 50 seated on the guide rail 12 is fixed to the fixing groove 18. The latch drive portion 30 is engaged with the latch 7, Is positioned to protrude to the outside of the door (3) and becomes stable.

The first door open mode refers to a state in which the latch 7 is pulled inside the door 3 and the user opens the door 3 while pushing the door handle 5. The drive shaft 10 is moved in the longitudinal direction by an external force and the center of the guide rail 12 deviates from the center of the door opening / As a result, the bearing portion 50 seated on the guide rail 12 moves out of the fixing groove 18 and moves along the guide rail 12, and the latch driving portion 30 moves the latch 7 to the inside of the door 3 So as to be pulled.

The second door open mode also means that the latch 7 is pulled inside the door 3 and the user opens the door 3 while pulling the door handle 5. The principle in which the latch 7 is pulled inward of the door 3 is the same as the first door opening mode.

When the external force acting on the drive shaft 10 is removed in the first door open mode and the second door open mode, the drive shaft 10 is returned to its original position by the resilient restoring force of the house spring 20. The center of the guide rail 12 coincides with the center of the door opening and closing apparatus 1 and the bearing portion 50 seated on the guide rail 12 is fixed to the fixing groove 18 and the latch drive portion 30 Is in a door closing mode in which the latch 7 is stabilized and stabilized so as to protrude to the outside of the door 3. However, the drive shaft 10 can vibrate longitudinally with a predetermined amplitude and a predetermined cycle by the single-swing motion of the house spring 20. However, due to the presence of the fixing grooves 18, the amplitude can be configured to decrease sharply according to the number of vibrations.
