Description

[Detailed Description of the Invention] The present invention relates to a confirmation device for electromagnetic locks for sliding doors and windows that can electrically confirm whether the door is closed and lock the door.

Crescent locks have been commonly used as locking devices for sliding doors in houses, etc., but if you want to check if the door is locked when you go out, for example, you have to go through each room in the house. It's extremely troublesome. Especially when going out for urgent business, it is inconvenient to double-check that the door is locked, and if a part of the door is forgotten, it is not desirable from a security perspective.

The present invention was devised to eliminate the above-mentioned drawbacks, and in an electromagnetic lock that is attached to the periphery of sliding doors and window openings in houses, etc., the electromagnetic lock is configured by combining an electromagnetic solenoid and a reed switch, and The central controller is connected to the operating switch and confirmation alarm (indicator light or audio) provided on the controller via an electric circuit, and the central controller is installed at a designated location, allowing you to lock all sliding doors and window openings and confirm that the doors are locked. This is done electrically. According to the embodiment of the present invention, when both the inside and outside sliding doors are completely closed, the electromagnetic lock is activated, the reed switch is turned on, and locking confirmation is displayed by lighting an indicator light or by a confirmation alarm such as a buzzer. Ru. If there is a defect in even one door being locked and the electromagnetic lock is not fully activated, the reed switch will not turn on and nothing will be displayed on the confirmation alarm, allowing you to discover an unlocked location. Depending on the size of the house, the electric circuit in the confirmation alarm of this invention can be assembled into one block for the entire house, or
Alternatively, you can open the openings in the house, for example, as shown in Figure 6, on the 2nd floor, room A, room B, room C on the 1st floor, room 2, etc.
The system can be divided into several blocks for each room, such as a home room, and set up as one system.

In Fig. 6, the electric circuit E is set up in a plurality of independent blocks for each room of the house (for example, A, B, H, D, H), and the electric circuit E is divided into a plurality of independent blocks for each room of the house (for example, A, B, H, D, H). , W2, W3) are each equipped with an electromagnetic lock 1.
A control switch 6 and a confirmation alarm 13 are installed on the central control device 5 installed at a desired position in the residential building.
are arranged in the same number as the number of blocks, and the electromagnetic lock 1 is arranged in the same number as the number of blocks.
It is connected to the. The electric circuit E in FIG.
Operation switch 6 and confirmation alarm 1 installed in
3, and connect the power solenoid 10 and reed switch 12 installed in the power lock 1 installed in each sliding door opening W1, W2, W3 to the operating switch 6, and connect the electromagnetic solenoid 10 and the power source F,
A reed switch 12 and a confirmation alarm 13 are connected to each other. Power source F uses a 24V battery and can be automatically charged with a 100V household AC power source. Therefore, this device can be used even if there is a power outage.

In addition, the confirmation alarm may be a display lamp, or may use a chime bell, a buzzer, or other audible alarm, as desired.

Next, the operation of the automatic electromagnetic lock for sliding doors according to the present invention will be explained according to the above structure.

When the operating switch 6 of the central operating device 5 set at a predetermined location is pressed, each electromagnetic lock 1 is activated from the power source F.
A current flows to the electromagnetic coil 10d of the electromagnetic solenoid 10, and when the current flows, an attractive force acts on the electromagnetic coil 10d to attract the iron core 10a. As a result, the restraining rod 8 fixed to the tip of the small diameter shaft portion 10c of the iron core 10a moves along the guide 2h against the restraining spring 9.
The locking rod 3 is released from the restrained state by retreating toward the electromagnetic coil 10d, and the bearing plate 2 is moved by the biasing force of the spring 7.
The locking rod 3 is rotated by a rotating shaft 3c that is pivotally supported by b and 2c.
rotates in the direction of arrow G in the rotation groove 2f, and rotates in the rotation groove 2f.
When the tip 3a of the locking rod 3 that protrudes from f rotates 90 degrees to block the sliding movement of the inner sliding door A, and further fits into the locking groove 4 of the outer sliding door B, the end 3d of the locking rod 3
The permanent magnet 11 attached to the permanent magnet 11 rotates and approaches the reed switch 12, and the reed switch 12 is turned on due to the change in magnetic flux, and the sliding movement of the outer sliding door B is interrupted. If both the inner and outer sliding doors A and B of all the sliding door openings are completely closed in block units, all the reed switches 12 are turned on, and electric current flows through the electric circuit E to the confirmation alarm 13 of the central controller 5. The confirmation alarm 13 is activated, and locking is confirmed by turning on the indicator light or giving an audio warning. However, if even one opening of the sliding door is not completely closed, the tip 3a of the locking rod 3 will contact and interfere with the indoor side surface of the inner sliding door A, or the locking groove 4 of the outer sliding door B will lock. The positions of the tips 3a of the locking rods 3 do not match and the tips 3a cannot fit into the locking groove 4, so the permanent magnet 11 attached to the end 3d of the locking rod 3
Since there is no correspondence between the reed switch 12 and the reed switch 12, there is no change in the magnetic flux and the electromagnetic lock 1 cannot operate completely.
Reed switch 12 does not turn on and confirmation alarm 1
3 does not work, and you can discover a locking defect. Also, pull the manual knob 10b to remove the iron core 10a.
If you slide the locking lever 8, the locking rod 8 will move back against the locking spring 9, releasing the locking rod 3 from the locking state and opening both the inner and outer sliding doors A, in the same way as when the operating switch 6 is pressed.
B can also be locked, so openings with poorly locked doors can be easily re-locked manually. After all the sliding door openings have been locked, the operating switch 6 is pulled to turn off the power F. When the power source F is turned off, no current flows through the electric circuit E, the electromagnetic coil 10d loses its attractive force, the iron core 10a slides in the direction of the rotation groove 2f due to the biasing force of the restraining spring 9, and the restraining rod 8 stops rotating. It protrudes into the moving groove 2f and returns to its original position to maintain the locked state more reliably. To return the electromagnetic lock 1 from the locked position to the unlocked position, hold the handle 3b of the locking rod 3 and lower the tip 3a of the locking rod 3 downward (in the direction of arrow H), and the biasing force of the locking spring 7 is released. Against this, the locking rod 3 contacts and presses the tapered part (not shown) of the restraining rod 8, and against the urging force of the restraining spring 9, the locking rod 8 presses against the electromagnetic coil 10.
When the locking rod 3 moves backward toward the d side and comes off the restraining rod 8, the tip 3a of the locking rod 3 rotates 90 degrees in the direction of arrow H.
Then, when the locking rod 3 rotates and becomes vertical, the restraining rod 8 is moved again by the urging force of the restraining spring 9 into the rotation groove 2f.
protruding into the interior, parallel to the front of the locking rod 3 (both sliding doors A,
B both sides). Therefore, the handle 3b of the locking rod 3
Even if the locking spring 7 is released, the biasing force of the locking spring 7 is suppressed by the restraining rod 8, and the locking rod 3 cannot be rotated and the unlocked state is maintained, and both sliding doors A and B can freely slide in the direction of movement. Can be done.

As described above, according to the automatic electromagnetic lock confirmation device for sliding doors of the present invention, it is possible to lock the door by pressing the operating switch on the central controller, and to easily confirm the locked state of the door using an electrical indicator light or voice. By installing the central controller in a predetermined location, you can quickly lock all sliding door openings in a building even from a distance when you want to quickly check that the doors are locked when you go out. You can check and lock the door all at once. The device of the present invention has a simple structure, yet can exhibit excellent effects as a locking device for sliding doors and windows that has both the functions of locking and confirming that the door is closed.
