Claims (4)

  1. A shoji screen, and a fixing portion provided on either the widthwise end of the shoji screen or another member that overlaps in the indoor/outdoor direction when the shoji screen is in the closed position that closes the opening, A hook portion is movably supported on the fixed portion and can be hooked onto the other side of the shoji screen and the other member, A rotating part is supported by the fixed part so as to be rotatable around the axis of rotation, A rotational force transmission unit transmits the rotational force of the rotating part around the rotation axis and transmits the rotational force to the hook part, A drive unit that rotates the aforementioned rotating part, An electric lock having a lock-side control unit that controls the drive unit, A transmitting unit that transmits an open signal to open the sliding door and a closed signal to close the sliding door, A control device having a receiving unit that receives signals from the transmitting unit, The aforementioned shoji screen is provided with an opening and closing device for opening and closing the shoji screen, and comprises The rotating part is A rotating cam curve portion that contacts the rotational force transmission portion and transmits the rotational force so that the hook portion rotates in the rotational direction, It has a linear movement cam curve portion that contacts the rotational force transmission portion and transmits the rotational force so that the hook portion moves in a linear direction in which the shoji screen and the other members move closer together and further apart, When the rotating part rotates, the rotating cam curve section and the rotational force transmission section perform one of the following actions: the action of rotating the hook section in the rotational direction, and the action of moving the hook section in the linear direction, by the linear movement cam curve section and the rotational force transmission section, followed by the other action . The transmitting unit and the receiving unit of the control device communicate wirelessly. The control device is The opening and closing device has a device-side control unit provided therein, The control unit on the device side, Upon receiving the opening signal, an unlocking signal is transmitted to the lock-side control unit to unlock the electric lock, and upon receiving a completion signal indicating that the electric lock has been unlocked, the opening operation is performed to open the sliding door via the opening/closing device. An electric locking system for building fixtures that receives the closing signal, performs a closing operation to close the sliding door via the opening and closing device, and transmits a locking signal to the lock-side control unit to lock the electric lock .
  2. The rotating part has a cam groove into which the rotational force transmission part is inserted. The electric locking door system according to claim 1, wherein the rotating cam curve portion and the linear moving cam curve portion are provided on the edge of the cam groove portion.
  3. The lock-side control unit is An electric locking door system according to claim 1 or 2, wherein the system recognizes the state in which the hook portion is rotated in the rotational direction and the state in which the hook portion is moved in the linear direction to determine when the locking is complete, as well as when the lock is unlocked, and controls the rotation of the rotating portion to restrict it in the state in which the locking is complete and when the lock is unlocked .
  4. The control device is Based on the aforementioned open signal, the electric lock is unlocked, and the sliding door is opened via the opening/closing device. The electric locking door system according to claim 1 or 2, wherein, based on the closing signal, the opening and closing device is used to perform a closing operation to close the sliding door and lock the electric lock.

Description

This disclosure relates to an electric locking system for building fixtures. Conventionally, locks that can be attached to building fixtures are known to be attached to one of the frame and the stile of the sliding door, fixing the other while pulling it in place (see, for example, Patent Document 1).

(First Embodiment) The following description of the electric lock-equipped door system according to the first embodiment will be based on the drawings. The following embodiments represent one aspect of the present disclosure and are not limiting, and can be modified at will within the scope of the technical concept of the present disclosure. In the following description, the direction that connects the outdoor side and the indoor side and runs horizontally will be referred to as the indoor-outdoor direction. The direction that is perpendicular to the indoor-outdoor direction and runs horizontally will be referred to as the width direction. The direction that is perpendicular to the indoor-outdoor direction and the width direction will be referred to as the vertical direction. In each component, the side that moves away from the center in the indoor-outdoor direction and the width direction may be referred to as the outside, and the side that moves towards the center may be referred to as the inside. As shown in Figures 1 and 2, the electric locking door system 100 comprises a frame 10, two sliding doors 16, 16, an electric lock 110, an opening/closing device 7, a transmission unit 8, and a control device 9. The frame 10 is formed in a four-sided frame shape. The two sliding doors 16, 16 are movable in the width direction inside the frame 10. The inside of the frame 10 corresponds to the opening described in the claim. The electric lock 110 locks and unlocks the two sliding doors 16, 16. When the sliding doors 16, 16 are in the closed position, closing the inside of the frame 10, the widthwise ends of the sliding doors 16, 16 are arranged to overlap in the indoor/outdoor direction.
