Description

  The present invention relates to a structure for preventing derailment of sliding doors used for partition doors, storage doors, furniture doors, and the like.

  Conventional sliding doors, particularly wooden sliding doors, are located in a groove provided in the upper part of the duck, and the lower part is fitted and erected without or provided with a door pulley in the groove provided in the sill. That is, it is erected by being supported by a rail provided in a sill groove or sill. For this reason, the construction work may be difficult, and derailment often occurs after the construction.

  In other words, when standing or traveling, the sliding door may come into contact with the vertical or adjacent sliding door, which may damage the vertical or sliding door. In order to avoid such a state, there is a method of building with a sliding door and a vertical or a large interval between the sliding door and the sliding door. However, this deteriorates the airtightness and impairs the beauty.

  When the sliding door warps to avoid such a state, it can be smoothly opened and closed even if the sliding door has a warp in the width direction, particularly a sliding door having means for avoiding contact with a vertical or adjacent sliding door. As a sliding door structure, a sliding door structure disclosed in Japanese Patent Laid-Open No. 9-41784 has been proposed.

In this conventional sliding door structure, a sliding door groove is provided on the upper surface of the door, and a rail support material that can change the position of the supporting portion in the sliding door in the thickness direction of the sliding door is embedded in the sliding door groove.
