Description

[Detailed Description of the Invention] The present invention relates to an electromagnetic lock for sliding doors and windows that can electrically lock sliding doors and windows.

Crescent locks have been commonly used as locking devices for sliding doors in houses, etc., but when you want to lock the door when you go out, for example, you have to go around the house to every room. Locking the door especially when going out for urgent business is extremely troublesome. It also has the disadvantage of being undesirable from a security perspective if one forgets to lock a part of the door.

The present invention was devised to solve the above-mentioned problems, and it connects an electromagnetic lock attached to the periphery of sliding doors and window openings of houses and other houses to an operating switch provided on a central operating device using an electric circuit. The central operating device is installed at a predetermined location, and all sliding doors and window openings are electrically locked from one location. According to the embodiment of the present invention, when both the inner and outer sliding doors are completely closed, the electromagnetic lock can be activated and locked. Depending on the size of the house, the electric circuit in the locking device of the present invention can be used to combine the entire house into one block, or to connect an opening in the house to a room on the second floor or a room as shown in Figure 6. Each room can be divided into several blocks, such as a room on the first floor, a room on the first floor, a room on the second floor, and a room on the first floor, and can be set up as one system.

The present invention will be explained in detail below with reference to Examples. In addition, although the example explains the case of both inside and outside sliding doors, 1
This can also be applied to real sliding doors (single sliding doors).

In Figure 1, A is the inside sliding door, B is the outside sliding door,
C is an upper frame on the periphery of the sliding door opening into which both the inner and outer sliding doors A and B are fitted, D is a crescent lock, and 1 is an electromagnetic lock installed on the inside of the lower surface of the upper frame C on the periphery of the sliding door opening.

Figures 2 and 3 show how the electromagnetic lock 1 is attached to the inside of the lower surface of the upper frame C around the opening of the sliding door.
A solid line indicates a locked state, and a two-dot chain line indicates an unlocked state.
A is an inner sliding door, B is an outer sliding door, and the outer sliding door B has a locking recessed groove 4 into which a tip 3a of a locking rod 3, which will be described later, can be inserted when both the inner and outer sliding doors A and B are completely closed. . The electromagnetic lock 1 has a mounting seat 2 formed in a lock case 2 of the electromagnetic lock 1 so that a locking rod 3 can rotate in a direction perpendicular to the movement direction of both the inner and outer sliding doors A and B.
It is fixed to the upper frame C at the periphery of the sliding door opening by a. 3
b is a handle for unlocking, 10b is a knob for manual locking, and it is desirable that the electromagnetic lock 1 does not protrude from the indoor side surface of the upper frame C around the opening of the sliding door.

Reference numeral 2 denotes a cylindrical lock case in which an electromagnetic solenoid 10, a locking rod 3, a locking spring 7, a restraining rod 8, and a restraining spring 9 are housed, and a mounting seat 2a having an L-shaped cross section is provided on one side of the cylindrical outer surface of the lock case 2. A rotation groove 2f is provided in the lock case 2 and opened in a 45-degree direction on the opposite side of the cylindrical outer contact surface of the lock case 2 of the mounting seat 2a to regulate the mounting position and rotation range of the locking rod 3. A locking rod insertion groove 2g is provided which communicates with the rotation groove 2f from one end of the cylindrical terminal of the locking rod 3, and the locking rod 3 is positioned in the rotation groove 2f, and both ends of the rotation shaft 3c of the locking rod 3 are connected to the bearing plate 2b,
2c, and locking springs 7 are fitted into both ends of the rotating shaft 3c so as to urge the locking rod 3 to rotate in the locking direction, and an electromagnetic solenoid 10 is attached to the other end of the cylindrical terminal of the lock case 2. The iron core 10a, which is installed internally and slides inside the electromagnetic coil 10d of the electromagnetic solenoid 10, is inserted into the bearing plates 2d and 2e, and the iron core 10a is inserted into the bearing plates 2d and 2e.
A sliding guide 2 is provided inside the lock case 2, with a restraining rod 8 fixed to the tip of the small diameter shaft portion 10c of a.
The restraining rod 8 is fitted so as to be slidable between h and 2h, and the restraining spring 9 is fitted into the small diameter shaft portion 10c of the iron core 10a on the bearing plates 2d and 2e, so that the restraining rod 8 is always on the locking rod 3 side. A manual locking knob 10b is fixed to the terminal portion of the iron core 10a so as not to be biased to protrude. The locking rod 3 has a tip 3a projecting from the rotation groove 2f at one end perpendicular to the rotation shaft 3c pivotally supported by the bearing plates 2b and 2c,
A handle 3b is formed at the tip 3a.

6 and 7 show an electric circuit E connecting the electromagnetic lock 1 and an operating switch 6 provided on the central operating device 5. FIG. In Figure 6, the electric circuit E is connected to each room of the house (for example, A, B, H, D, H).
Set the unit into multiple independent blocks, and set the sliding door openings of each room (for example, W1, W2, W
3), an electromagnetic lock 1 is installed in each of the blocks, and the same number of operating switches 6 as the blocks are arranged on the central operating device 5 installed at a desired position in the house. As explained, it is connected to the electromagnetic lock 1. The electric circuit E in FIG. 7 is configured as one independent block for each room, and connects a power source F provided in the central controller 5 and an operating switch 6 provided in the central controller 5.
A power solenoid 10 housed in an electromagnetic lock 1 installed in each sliding door opening W1, W2, W3 is connected to an operating switch 6, thereby connecting the electromagnetic solenoid 10 and a power source F, respectively. 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.

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.
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 then fits into the locking groove 4 of the outer sliding door B to block the sliding movement of the outer sliding door B. Then, both the inner and outer sliding doors A and B of all the sliding door openings are completely closed in block units. Furthermore, when the manual knob 10b is pulled and the iron core 10a is slid, the restraining rod 8 moves back against the restraining spring 9, releasing the locking rod 3 from the restrained state, and when the operating switch 6 is pressed. Similarly, both the interior and exterior sliding doors A and B can also be locked manually. When all the sliding door openings have been locked, pull the operating switch 6 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 biasing force of the restraining spring 9, the restraining rod 8 retreats toward the electromagnetic coil 10d, and the locking rod 3 is deterrent rod 8
When it comes off, the tip 3a of the locking rod 3 will move in the direction of arrow H.
Rotate 90 degrees. When the locking rod 3 rotates and becomes vertical, the restraining rod 8 is again projected into the rotation groove 2f by the biasing force of the restraining spring 9, and is located parallel to the front surface of the locking rod 3 (on both sides of both sliding doors AB). Therefore, even if you release your hand from the handle 3b of the locking rod 3, 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 are moved in the moving direction. It can slide freely.

As described above, according to the automatic electromagnetic lock for sliding doors of the present invention, the lock can be easily electrically locked by pressing the operating switch on the central controller, making it easy to lock the door in a hurry when going out. By installing the central operating device at a predetermined location, all sliding door openings in the building can be quickly locked at once even from a distance. The electromagnetic lock of the present invention has a simple structure and can exhibit excellent effects as a locking device for sliding doors and windows.
