Here, the attracting piece is another magnet attracting each other with the magnet, or a metal piece attracted to the magnet, and it is easy to open the sliding door body from a closed state where the magnet and the attracting piece are fixed by magnetic force. Therefore, it is also disclosed that an electromagnet can be provided on the sliding door body side, and the current flowing through the electromagnet can be cut when a pulling hand is pulled in the direction of opening the sliding door body.

  Moreover, although it is related with a revolving door instead of a sliding door, in Patent Document 2, a permanent magnet is provided on a side surface that is joined and locked with a vertical frame locking material of a door material made of a paramagnetic material or a nonmagnetic material. The opening / closing door body is disposed so that one side thereof is exposed with an interval that is not affected by the magnetic force, and opposed to the permanent magnet of the opening / closing door body when the vertical frame locking member is closed. In such a position, one side surface of the control magnet on which an electromagnetic coil for generating a magnetic field capable of converting the magnetic pole is formed on the outer periphery of a magnet body made of a permanent magnet having a different polarity from the permanent magnet is exposed. The security door provided with the vertical frame latching body made is disclosed.

  Similarly, it relates to a rotating door. However, in Patent Document 3, an electromagnet is built in the door contact portion of the door frame or inside the door main body, and the door is locked and unlocked by using the electromagnetic force, the attractive force, etc. of the electromagnet. An electromagnet locking device is disclosed. Here, in order to prevent breakage at the time of opening and closing or collision, it is possible to install it on an existing door by covering the electromagnet with a steel plate etc. and fixing it to the door contact part. In the case of a magnetic body, it also describes that a receiving metal fitting is attached to a member in contact with the electromagnet. In addition, locking / unlocking can be done separately using indoor switches, remote control from the outside (remote control, etc.), locking / unlocking using a cylinder lock or thumb turn, numeric keypad lock, card lock, fingerprint lock, etc. It is also described that a method is used by mixing them.

However, none of the patent documents disclose a specific mounting structure for the electromagnet and the suction plate that is attracted to the electromagnet, and how to attach the electromagnet and the suction plate to the sliding door with the door-to-door cushion and its frame. There is no description about whether to incorporate it. In addition, in the case of a sliding door locking / unlocking system using an electric signal, an electric lock was used. Wiring must be performed, and problems such as disconnection and contact failure occur. In addition, when changing from a manual lock to an electric lock, it is necessary to manufacture and replace a door stop frame, a sliding door main body, etc., resulting in an increase in cost. Also, if you force it afterwards, it will damage the beauty.
