(Technology)

The present invention relates to a sliding door, and more particularly, to a stepless sliding door in which all the doors are positioned on the same plane in a closed state so that no step is formed between the doors.

(Background)

Sliding doors are widely used in combination with sliding doors for doors such as furniture and windows.

5 is a schematic view of a conventional general sliding door.

As shown in the drawing, a conventional general sliding door 100 is a structure in which two or more doors 120 are alternately mounted on different guide rails 110 between two upper and lower guide rails 110 formed side by side. It is a door having a structure of sliding (120) so that the two doors (120) overlap on the same side and open (A in Fig. 9) and close (B in Fig. 9) when they are spaced apart from each other.

In the case of such a sliding door 100, because the two doors are located on different guide rails 110, when looking at the sliding doors in the closed state of all doors, a step 130 is formed between the door and the door As such, the step 130 is a factor that impairs the aesthetics of the door as compared with no step.

In particular, in the case of furniture such as built-in cabinets or cabinets, it is common to apply various decorations (eg, cadet cadets) to the surface of the door, and the conventional sliding door 100 is a decoration because such a decoration is cut to reach the step (130) There is a problem in maximizing the effect.

As an attempt to eliminate the step of the sliding door 100, the 'integrated sliding window' of Korea Utility Model Registration No. 183485 (registered on March 14, 2000) is limited, and the window of 485 is divided between two lines of guide rails. It is characterized in that the pulley is formed to be rotatable so as to form a connection rail of the curved portion to connect and to slide the connection rail of the curved portion.
