The locking device is provided separately from the door and includes a signal transmitting device that transmits a signal for controlling the locking member.

Further, the frame is provided in a house, a door is provided inside the frame and is provided to open and close an opening of the frame, and the frame includes a signal receiving device and a signal receiving device. And a locking device that is provided with an electromagnetic drive device that operates in conjunction with the reception and a locking member that protrudes toward the opening of the frame by the electromagnetic drive device and locks the door. The electromagnetic drive device is a locking device provided on the frame side fixed to a house and driven by being connected to a commercial power supply.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a locking device 10 of the present invention. A door 14 is attached to a frame 12 formed on a wall 11 of a building with a pair of hinges 16, and the door 14 is provided with a knob 18. I have. An electromagnetic drive device 20 is provided inside the wall 11 near the door 14, and the electromagnetic drive device 20 has a rod-shaped engagement member that protrudes and retracts from the frame 12 toward the door 14 and locks the door 14 when it protrudes. A stop member 22 is provided. The locking member 22 reciprocates in the horizontal direction by the electromagnetic driving device 20. The locking member 22 has a slidable clearance and is inserted into a hole 24 opened to the door 14 side. Further, a hole 26 communicating with the hole 24 is formed in the door 14 at a position corresponding to the hole 24 provided in the frame 12.

The electromagnetic driving member 20 includes a driving device including an electromagnet (not shown), and is connected to a driving circuit 28 for driving the locking member 22 to protrude and retract as shown in FIG. A wiring 30 connected to a commercial power supply is connected to the drive circuit 28, and electricity is supplied from the commercial power supply.
Further, the drive circuit 28 is provided with a reception control device 32 that receives a signal from a wireless signal transmission device 40 described later and controls the drive circuit based on the signal.

The reception control device 32 includes a reception device such as an antenna 34, and receives a radio signal from a signal transmission device 40 provided with a door key 36 that is manually opened and closed.
When the electromagnetic drive member 20 receives the signal, the reception control device 3
2 through a drive signal from the drive circuit 28. The door key 36 can be inserted into the manual operation section 37 of the electromagnetic drive device 20, and the locking member 2 can be manually operated.
2 can be pushed and retracted.

The signal transmitting device 40 transmits a predetermined radio signal for moving the locking member 22 up and down separately from the frame 12 and the door 14. The signal transmitting device 40 is portable and is integrated with the door key 36, and a transmitting circuit 42 is provided at a base end thereof. The signal transmission device is provided with a lock button and an unlock button (not shown). The signal to be transmitted may be any radio wave, ultrasonic wave, infrared ray, or the like.

Next, a method of using the locking device 10 will be described. First, when locking, the door 14 is closed to the frame 12, a locking signal is transmitted from the portable wireless signal transmission device 40, the electromagnetic drive device 20 is operated, and the locking member 22 is moved to the door 1.
4, and the tip of the locking member 22 is inserted into the through hole 26 of the door 14. When unlocking, an unlocking signal is sent from the wireless signal transmitting device 40, a signal flows to the drive circuit 28 via the antenna 34 and the reception control device 32, and the electromagnetic drive device 20 is operated to lock the locking member 22. It is evacuated into the frame 12.

According to the locking device 10 of this embodiment, locking and unlocking can be performed remotely, which is simple and convenient. Moreover, since the electromagnetic drive device 20 is provided inside the wall 11 and the like and is a fixed member, it can be easily connected to a commercial power supply. Further, since the wall 11 is hardly affected by the vibration caused by opening and closing the door 14, the electromagnetic drive device 22 is not affected by the vibration, and is safe. In particular, the electromagnetic drive 20
By providing the space in the ventilation wiring space on the wall, there is no need to create a special space, and the space can be easily stored.
When 2 is an extruded aluminum material, it can be placed more easily and reliably in the space of the shape material by arranging the power supply wiring along the space such as the groove of the shape material. it can.

The locking device 10 has a through hole 26 formed in the wall 11 as shown in FIG.
4, the locking member 22, and the electromagnetic drive device 20 may be provided. In this case, the electromagnetic drive device 20 is provided with a battery (not shown) or wiring is provided up to the periphery of the door, and the frame 12 and the wall 11 are provided near the hinge 16 so that the rotation of the door 14 is not hindered. Continuously connected to commercial power.

The locking device for a house according to the present invention is not limited to the above embodiment, and can be used for a revolving door, a window, a sliding door, a gate, and the like of a building other than the entrance door. In the case of a sliding door, the shape of the locking member includes, for example, a locking member having a L-shaped tip, and the locking member is rotated by an electromagnetic driving device, and the L-shaped tip portion moves circularly. It protrudes outside the frame. Further, a locking member may be provided on the upper frame or the lower frame to lock. In addition, the power supply may be a commercial power supply, a type using various batteries, or a type using a solar cell or the like.

[0016]
