In the handle device 100 of the sliding door according to the present invention configured as described above, when the locking knob 130 is moved downward while the sliding door 200 is closed, the hook portion 161 of the locking hook 160 is the sliding door ( Protruding to the outside of the 200 is caught in the locking hole (not shown) formed in the door frame to lock the sliding door 200.

When the lock door 130 is to be released, the lock hook 130 is moved upward so that the lock hook 160 exiting from the lock hole of the door frame is received into the lock case 140 and the sliding door ( Since the 200 does not protrude to the outside, the sliding door 200 can be opened.

Figure 6a is a front view of the inside of the lock case of the sliding door lock state of an embodiment of the present invention, Figure 6b is an inside front view of the lock case during the sliding door unlocking or locking process of the embodiment, Figure 6c An interior front view of the sliding door unlocked state of the embodiment is shown.

In the handle device 100 of the sliding door of the present invention in the locked state of the sliding door 200 as shown in Figure 6a the hook portion 161 of the locking hook 160 protrudes to the outside of the lock case 140 to lock the door frame Caught in the hole.

When the locking knob 130 is moved upward to release the sliding door locking state, one end of the connection link 150 connected to the locking knob 130 is moved upward, thereby connecting the connection link 150. Is rotated in a clockwise direction about the hinge connecting shaft 154, the lock hook 160 connected to the lock hook connection hole 153 of the other end of the connection link 150 is rotated counterclockwise while locking hook The hook portion 161 of the 160 is accommodated in the lock case 130.

Rotation guide protrusion of the hinge connecting shaft 154 and the locking hook 160 of the connection link 150 in the process of rotating the connection link 150 in the clockwise direction and the rotation of the lock hook 160 in the counterclockwise direction The spring 170 installed between the 162 is compressed to a section in which the hinge connecting shaft 154, the rotation guide protrusion 162, and the hinge connecting protrusion 163 are arranged in a straight line, and then expand again when the spring is passed through the section. do.

Therefore, when releasing the locked state, the locking knob 130 is raised only to a section in which the hinge connecting shaft 154, the rotation guide protrusion 162, and the hinge connecting protrusion 163 are arranged in a straight line. Even if the force is not applied to the 130, the connection link 150 and the lock hook 160 are rotated through the elastic force of the spring 170, the person who operates the lock knob 130 when passing the section is clicked I can feel it clearly so that it is unlocked.

As shown in FIG. 6C, the hook portion 161 of the lock hook 160 is accommodated into the lock case 130 and the elastic force of the spring 170 is connected to the connection link 150 when the sliding door 200 is unlocked. The clockwise rotation and the locking hook 160 acts in the counterclockwise direction, so that the stable unlocking state can be maintained.

In the unlocked state, as shown in FIG. 6C, the hook part 161 of the locking hook 160 is accommodated into the lock case 130 and does not protrude to the outside of the sliding door 200, thereby closing the sliding door 200. At this time, since the hook part 161 does not collide with the door frame, there is no damage to the parts of the door frame or the handle device 100.

On the other hand, when closing the sliding door 200 so that it can not be opened from the outside when moving the locking knob 130 in the lower state when the connection link 150 is rotated counterclockwise and at the same time the locking hook 160 While rotating clockwise, the hook 160 of the locking hook 160 protrudes to the outside of the sliding door 200 and is caught by a locking hole provided in the door frame.

In the sliding door locking process, the locking knob (130) of the hinge connecting shaft 154 of the connection link 150, the rotation guide protrusion 162 of the locking hook 160, and the hinge connecting protrusion 163 are arranged in a straight line. When the 130 is lowered, the connection link 150 and the lock hook 160 are rotated through the elastic force of the spring 170 even though the locking knob 130 is not applied thereafter. A person who operates the knob 130 may feel a click to clearly recognize that the handle 200 is locked.

The present invention described above is not limited to the above description, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be obvious to you.
