The present invention relates to a sliding door device, and more particularly to a rotatable sliding door device that the lower portion of the sliding door does not shake.

In general, the sliding door device means that the door can be opened and closed by sliding the door toward the rail of the door frame, not the front or rear of the door frame. These sliding doors have been developed as a multi-stage sliding door to further widen the entrance.

Figure 1a is a perspective view showing an example of such a general sliding door device. As shown, the user moves the doors 11, 12, and 13 arranged in multiple stages to be stacked on one side to enter or exit through the door to form an entrance and then move there.

By the way, the general sliding door device 10 as described above has a lower bar that is the lower end of the door frame 14, which not only becomes a stumbling block when the user transfers a large object or furniture, but also has a problem that dust accumulates and is difficult to clean. .

In order to solve the above problems, a sliding door device 20 without a bottom bar is employed in FIG. 1B.

Referring to the drawings, the sliding door device 20 includes a door frame 24 having a lower end, that is, no bottom bar, and doors 21, 22, 23 arranged in multiple stages. This is because the lower end of the door frame 24 is opened, the doors 21, 22, 23 are moved to be superimposed on one side, and then a large object or furniture can be easily moved to the formed space.

However, the sliding door device 20 as described above is shaken because the lower part of the sliding door is not fixed when sliding, and thus there is a problem that the sliding door device does not operate stably.

The present invention was devised to solve the above problems, and an object of the present invention is to provide a rotatable sliding door device having an improved structure such that the lower portion of the sliding door does not shake and slides stably.

The rotating door frame 120, as shown in Figure 2c, rotatably coupled to one side of the inner peripheral surface of the frame (110). To this end, as shown in FIGS. 4 to 7, the revolving door frame 120 and the frame 110 are coupled by a hinge 190, and the revolving door frame 120 is coupled to the hinge 190. Can rotate forward or backward. As the hinge 190, a hinge hinge or a hydraulic hinge may be used. In FIGS. 4 to 7, the hydraulic hinge for inducing smooth operation by preventing a sudden swing operation by hydraulic pressure is illustrated. Doing. Here, the number of the hinge 190 and its coupling position may vary depending on the case. The revolving door frame 120 may also be manufactured using the same material as the frame 110.

As shown in FIG. 2A, the fixed door frame 130 is fixed to a portion of the inner circumferential surface of the frame 110 except for the coupling portion of the revolving door frame 120. The fixed door frame 130 may also be manufactured using the same material as the frame 110. In addition, the fixed door frame 130 may alternatively be integrated with the frame 110.

The fixed door 140 is fixed to the inside of the rotary door frame 120, the first guide rail 141 is formed in the sliding direction on the lower side.

As shown in FIG. 2B, the first sliding door 150 is slidably coupled to the inner side of the revolving door frame 120 and the fixed door frame 130, and the fixed door 140 and the first door are slidably coupled to each other. The sliding door 150 is arranged to be stepped to avoid interference with each other during sliding. In addition, a second guide rail 151 is formed in the sliding direction at the lower side of the side portion facing the fixed door 140.

The second sliding door 160 is slidably coupled to the inside of the rotating door frame 120 and the fixed door frame 130, the first sliding door 150 and the second sliding door 160 is It is arranged to be stepped to avoid interference with each other during sliding. On the other hand, in the present embodiment is illustrated as having two sliding doors, this is for convenience of description, the number of sliding doors may be one or three or more.

As shown in FIG. 3A or 3B, the first anti-shake means 170 has one end fixed to the lower side of the first sliding door 150 and the other end of the first guide rail of the fixed door 140. The first guide roller 171 moving along the 141 is provided. Therefore, the first sliding door 150 is connected to the fixed door 140 by the first anti-shake means 170, so that the doors 140, 150 and 160 are slid or folded to one side to the front or the rear. It can operate stably when rotating. In addition, it is possible to prevent the lower portion of the first sliding door 150 from shaking.

The second anti-shake means 180 has one end fixed to one lower side of the second sliding door 160 and the second guide moving along the second guide rail 151 of the first sliding door 150 at the other end. The roller 181 is provided.
