Description

  The present invention relates to a fitting having a sliding door shoji.

  As a fitting with a sliding door shoji, for example, there is a fitting for a sliding window that has an opening frame and two right and left shojis, and that opens and closes by sliding only one of the shojis in the left and right direction with respect to the opening frame. (For example, refer to Patent Document 1). Such a joinery has a stopper member that is rotatably provided at the door stop portion of the opening frame. When the shoji is opened, the stopper member pivots to protrude toward the shoji and closes the shoji. Sometimes, the door of the shoji is brought into contact with the stopper member so that the shoji is restricted from moving at a position spaced from the door stop.

  When closing the shoji with restricted movement, the release member provided at the door of the shoji is closed by holding the stopper member with the hook member in a state where the stopper member is rotated and accommodated on the opening frame side, and the shoji is closed. The state of being engaged and held with the hook member is released. The stopper member released from the held state at this time is in a state of being inclined so that the tip abuts against the door tip of the shoji with the shoji being closed.
