In addition, between the first roller support bracket 110 and the roller 100 is mounted a speed reducing plate spring 113, the plate spring is made in the form of a ring, but at the same time in the form of a wave form roller Prevents you from moving too fast.

In other words, if the speed reducing plate spring is not installed, the roller may move at too high speed when moving on the rail, and the door may collide with the door frame. However, when the speed reducing plate spring is installed as in the present invention, the leaf spring is installed. This action pushes the rollers outward so that the rollers can move slowly.

Looking at the height adjustment operation of the door as follows.

The rail 40 is installed in the horizontal direction at a constant height of the door frame 30, the roller 100 is connected from the outer door 10 or the inner door 20 using the door connection bracket 140 and the rail (40) It is installed on the opposite side of the rail by rolling over.

On the other hand, when the roller 100 is positioned above or below the rail 40, the roller 100 must be raised or lowered. When the roller 100 is positioned above the rail 40, the height adjusting bolt Rotate 131 in a counterclockwise direction so that the wedge-shaped height adjusting hole 132 is forcibly advanced while being released from the bolt 131. At this time, the height adjustment bolt 131 is installed so as to rotate freely, and thus the position of the height adjustment bolt 131 does not change, only the wedge-shaped height adjustment hole 132 connected to the height adjustment bolt 131 is reciprocated to the left and right do.

Then, the wedge-shaped height adjusting unit 132 lowers the first roller support bracket 110 along the long hole about the second roller support bracket 120 and accordingly the first roller support bracket 110 and the first roller support bracket 110. 2 When the roller 100 installed on the first roller support bracket 110 is gradually lowered while the upper surface of the roller support bracket 120 is opened, and the roller 100 is lowered to a desired position, the height adjusting bolt 131 ) To stop the rotation.

In addition, when the roller 100 is positioned below the rail 40, the play adjustment bolt 131 is rotated in a clockwise direction so that the wedge-shaped height adjusting holes 132 enter the bolt 131 and are forced to retreat. .

Then, the first roller support bracket 110 is raised about the second roller support bracket 120 so that the wedge-shaped height adjusting hole 132 rises, and thus the first roller support bracket 110 and the second roller are supported. As the upper surfaces of the roller support brackets 120 become closer, the rollers 100 installed on the first roller support brackets 110 may rise.

In fact, when there is no member separately supporting the lower portion of the roller 100 and seated on the rail 40, the second roller support bracket 120 descends according to the weight of the door, thereby lowering the first roller support bracket 110. As a result, the gap between the roller 100 and the roller 100 are raised, as if the rail 40 pushes the roller 100 up.

As a result, when the wedge-shaped height adjusting opening 132 enters by manipulation of the height adjusting bolt 131 located at the side of the door 10, the rail 40 and the roller 100 are fixed, and thus the first roller is supported. When the bracket 110 is raised around the second roller support bracket 120, the door 10 is raised, and when the wedge-shaped height adjusting hole 132 is retracted, the first roller support bracket ( 110 is lowered about the second roller support bracket 120 has the effect that the door is lowered.

At this time, the long hole 111 serves to define a section in which the first roller support bracket 110 rises and falls around the second roller support bracket 120 and at the same time stably does not leave the outside. The roller support bracket 110 is raised and lowered.

Subsequently, when the outer door 10 is driven while the height of the outer door 10 is adjusted, the door connecting bracket 140 moves and at the same time the roller moves along the rail.

On the other hand, since the configuration and operation of moving the inner door 20 is the same as the outer door, further description will be omitted.

Looking at the height adjustment device 200 of the support for departure prevention of the present invention are as follows. The height preventing device for the departure preventing support of the present invention comprises a door fixing bracket 210, a support separation preventing means 220, a guide piece 230, and a support height adjusting means 240.
