Description

DETAILED DESCRIPTION OF THE INVENTION The present invention brings at least two doors into a closed state on a plane by abutting each other at their inner ends in an opening of a cabinet, etc., and from this state, one door opens. This invention relates to a plane closing and sliding door rail for outset and insesoto applications, in which the door is brought into an open state by moving one door to the front side of another door so as to overlap with the other door.

Conventional general sliding doors create a step between the doors, which detracts from the aesthetics of the design, so the above-mentioned flat-closing sliding doors have begun to be used more frequently. If a gap is not provided between the butting end faces, the doors cannot be opened and opened in a stacked state, so it is not possible to completely close the door, and the butting end faces of both doors may not be chamfered into an inclined state. There are various problems in terms of use, production, and cost, such as the inability to open and move without doing so.

Therefore, the present invention was developed in view of the above-mentioned conventional problems.
Two rollers or the like are provided at the upper and lower ends of both the left and right doors, and are provided on a bracket fixed to the outer end in the width direction of the door, and an arm extending from the bracket toward the inner end. A door rail for the earth wall and a door rail for the lower wall are provided on the earth wall and the lower wall of the door mounting frame so that the traveling bodies are movably fixed and guided. On both left and right sides of the straight part, there are sloped parts curved backward and evacuation parts connected to the rear in a substantially orthogonal manner to the straight part, so that when the door is first opened, the door rotates forward. In addition, when the door is opened, the door moves in a stacked state, and the above-mentioned bracket and arm can be stacked on each other. The body provides stable support for the door, allows for a large opening amount, and allows the gaps between the door and the two walls and the bottom wall to be extremely small, and furthermore, the mutually abutting ends of the doors are cut out in a diagonal manner. The purpose is to make it possible to create a completely closed door without any gaps, to easily form it with a single rail, and to be able to easily install it at low cost. .
