Description

  The present invention relates to a structure of a lock receiving member that receives a dead bolt that advances from a lock mechanism portion of a lock device provided in an opening / closing body such as a door or a sliding door.

  The lock mechanism part that constitutes the lock device provided in the opening / closing body such as a door or sliding door is provided with a dead bolt that moves forward and backward with respect to the opening of the opening / closing body, and is provided on the building-side frame facing the opening. The received receiving member is adapted to receive the advancing deadbolt. This receiving member is generally referred to as “troyoke”, and is formed in a substantially box shape with one surface opened, and is configured to fit within the frame body. In addition, this receiving member narrows the area of the opening and serves as an entrance for dead bolts. It is covered with a strike plate having an opening, and is fixed together with this strike plate by a fixing means such as a screw.

  In the past, Troyoke used as a receiving member was obtained by forming a single plate into a box shape by bending (see Patent Document 1) or pressing, but in recent years, it has been attached together with the side plate and strike plate. The substantially frame-shaped member comprised with a piece is used as a troyoke, and the board member used as the bottom of a box structure is combined as a troyoke cover. By making these troyoke and troyoke cover separate structures, it is possible to select materials by dividing each function and to simplify the machining process in the case of bending.
