Description

[Detailed Description of the Invention] The present invention relates to a sliding door device in which at least two sliding door shoji are installed in a door frame in a sliding manner.

In conventional sliding door devices, the door frame is composed of left and right vertical frames and upper and lower horizontal frames, and the upper and lower horizontal frames have concave grooves and convex rails for slidingly guiding the upper and lower ends of each sliding door shoji. Each sliding door shoji installed in the door frame is opened and closed by sliding along these concave grooves and convex rails. However, with this type of sliding door device, the shoji only moves left and right within the door frame, so in the case of a two-panel sliding door shoji, for example, even if the shoji is opened to the maximum, only half of the opening in the door frame can be opened. Therefore, there was an inconvenience that the shoji had to be removed when furniture, etc. that was wider than the opening when the shoji was fully opened was to be taken in or out through the door frame opening. Additionally, since the rails protrude from the top of the lower horizontal frame of the door frame, it is easy for dirt and water to accumulate between the rails, making it difficult to remove the accumulated dirt and creating a risk of tripping. .

This invention was created in view of the above, and allows the opening of the door frame to be opened from the front without removing the shoji, as well as eliminating the need for rails on the door frame, making it easy to remove and ensuring safety. The purpose is to provide a sliding door device.
