Located on the side, the other magazine piece is located on the rear wall of the case (10).

The outer surface of the blade 20 formed as described above is made of a curved surface so that the striker 6 (see Fig. 1) can easily enter.

At the same time, the hinge shaft 14 (see FIG. 3) is provided with a latch 24 (see FIG. 3) which is rotated by the striker 6 (see FIG. 1), and the latch 24 has a hinge shaft 14. A mass 26 is slip-bonded to a side surface of the mass 26, and a finger 28 (see FIG. 3) contacting the striker 6 (see FIG. 1) is inclined upward at a predetermined angle on one side of the mass 26. It is formed while being formed, the pressure (30) for transmitting the action force is formed on the other side is extended to the outside.

In addition, a groove 32 penetrating in the longitudinal direction is formed inside the mass 26, and a torsion spring 34 providing an elastic force to rotate and return to the original position is located inside the groove 32. While being coupled to the hinge shaft 14.

At this time, one of the tunggi pieces of the torsion spring 34 is located on the mass 26 side, the other tunggi pieces are located on the rear wall of the case (10).

On the bottom surface of the case 10 is a limit switch 36 which provides information that the striker 6 (see FIG. 1) is located on the locking device 4 (see FIG. 3) as the latch 24 rotates. The bar 38 constituting the limit switch 36 is located close to the pressure 30 of the latch 24.

Subsequently, a solenoid 40 for intermittent rotation of the rocker 16 is provided on the bottom surface of the case 10 with a rod 42, and a bottom of the arm 18 is provided at the tip of the rod 42. The support plate 44 is coupled.

And the solenoid 40 is coupled to the bar-shaped bracket 46 bent to the letter "a", the bracket 46 is a fixing screw 48 and the adjustment screw 50 on the rear wall of the case 10 It is installed to be coupled to the rear wall of the case 10, the adjustment screw 50 is coupled to the slot 52 to change the position of the solenoid 40 is formed through a predetermined length in the transverse direction. .

A switch 54 is provided on the inner surface of one side wall of the case 10 to provide information that the solenoid 40 has been operated. The switch 54 is installed to be in contact with the front surface of the support plate 44.

On the other hand, the limit switch 36, the solenoid 40 and the switch 54 is connected to a control unit 56 (installed in the central control room) for grasping the current situation based on the information provided, and the control unit 56 has an emergency An alarm light 58 indicating the situation is connected.

The upper part of the case 10 is sequentially coupled to the guard (60) serving as a cover, and a fixing plate 62 (see Fig. 3) for fixing the case 10 to the door frame 2 (see Fig. 1).

The inclined surface 64 (see FIG. 3), on which the striker 6 (see FIG. 1) is placed, is formed at a predetermined angle and is formed on the guard 60 installed as described above. In the middle portion, a guide hole 66 (see FIG. 3) is formed through which the finger 28 of the latch 24 can contact the striker 6 (see FIG. 1).

Referring to the operation of the present invention configured as described above are as follows.

In the daytime during frequent access, the control unit 56 (see FIG. 3) cuts off the current supplied to the locking device 4. In the above state, the rod 42 of the solenoid 40 is in a backward state so that the support plate is reversed. 44 is displaced from the position where the arm 18 of the rocker 16 rotates.

Referring to the operation of the locking device 4 in the above state is as follows.

First, when applied to a commonly used door as a mode (general use), when the door 8 (see FIG. 1) is opened as shown in FIG. 9A, the striker 6 is locked by the locking device 4. When the door 8 (see FIG. 1) is closed, the striker 6 enters the locking device 4 and presses the outer surface of the blade 20 as shown in FIG. 9B. In this case, the blade 20 is made of a curved surface and the end of the striker 6 is made of an inclined surface, the blade 20 is lowered by the striker (6).

As described above, when the blade 20 is lowered, the arm 18 rebounds against the elastic force of the torsion spring 22 (see FIG. 3) on the hinge shaft 14, thereby raising the blade 20 by reverse rotation.

Subsequently, the striker 6 (see FIG. 9C) moves forward and lowers to coincide with the inclined surface 64 while pressing the finger 28 of the latch 24 as shown in FIG. 9C. ) And the mass 26 formed integrally with each other rotate on the hinge shaft 14 while reacting to the elastic force of the torsion spring 34 (see FIG. 3), and at the same time the pressure 30 is shown in FIG. 9D. It is spaced apart from the bar 38 of the limit switch 36.

Thus, the limit switch 36 is turned off.

As described above, when the striker 6 moves away from the blade 20 and moves toward the finger 28, the arm 18 rotates in the reverse direction by the repulsive force of the torsion spring 22 (see FIG. 3) and descends. One blade 20 (see Fig. 9C) is raised to return to its original position.

Thus, the striker 6 is trapped inside the locking device 4 (see Fig. 1) by the raised blade 20, and the door 8 is closed.

Contrary to the above, when the door 8 is opened, the striker 6 leaves the finger 28 (see FIG. 3), and the latch 24 rotates in the reverse direction by the repulsive force of the torsion spring 22. It will return to the position of.

Therefore, the finger 28 is raised to protrude onto the inclined surface 64 of the guard 60, the pressure 30 is to press the bar 38 of the limit switch 36, the limit switch 36 To be turned on.

Subsequently, when the striker 6 (see FIG. 1) leaves the locking device 4 while pressing down and lowering the inner surface of the blade 20 (see FIG. 3), the blade 20 is connected to the torsion spring 22. It returns to its original position with the arm 18 rotating by the elastic force.

As a result, when the striker 6 (see Fig. 1) leaves the locking device 4, the door 8 is opened.

On the other hand, if the employee wants to control access after leaving the office, as shown in the flowchart of FIG. 11, the control unit 56 (see FIG. 3) located in the central control room closes the door 8 and supplies current to control the door. (S1)

When the current is supplied after S1, the solenoid 40 operates. (S2)

As described above, when the solenoid 40 is operated, the rod 42 moves forward to reach the position at which the arm 18 of the latch 24 rotates, and at the same time, the support plate 44 moves to the case 10. Turn on the switch 54 installed on the side wall.

After S2, the controller 56 determines whether the switch 54 is in the on state. (S3)

As described above, it is possible to determine whether the solenoid 40 is operated according to the on / off state of the switch 54. When the switch 54 is in the off state, the control unit 56 is the solenoid as described above. The operation command is again sent to (40).

After S3, the controller 56 determines whether the limit switch 36 is in an off state (S4).

When the limit switch 36 is in the off state, the striker 6 (see FIG. 1) presses the finger 28 of the latch 24 (see FIG. 3) to rotate on the hinge shaft 14. As the pressure 30 is in the state where the bar 38 of the limit switch 36 is spaced apart, it can be determined that the door 8 (see FIG. 1) is closed.

Unlike the above, when the limit switch 36 (see FIG. 3) is turned on, the striker 6 (see FIG. 1) is separated from the finger 28 of the latch 24 (see FIG. 3). Since the torsion spring 34 installed in the latch 24 rotates in the reverse direction, the pressure 30 is in a state in which the bar 38 of the limit switch 36 is pressed, so that the limit switch 36 is turned on. In this case, it can be determined that the door 8 (see Fig. 1) is open in the situation room.

If the limit switch 36 (see Fig. 3) is not in the OFF state after the step S4, the control unit 56 turns on the warning light 58 (S5).

In addition, when the limit switch 36 is in the OFF state after S4, the controller 56 determines whether the switch 54 is in the OFF state (S6).

When the switch 54 is turned on, the current is supplied to the solenoid 40, and the rod 42 and the support plate 44 are advanced. If the switch 54 is turned off, the current is supplied to the solenoid 40. This is interrupted | blocked and the rod 42 and the support plate 44 will be in the state which receded.

If the switch 54 is off after S6, the warning lamp 58 is turned on. If the switch 54 is not in the off state, it is again determined whether the limit switch 36 is in the off state.

On the other hand, if you want to use the lock device 4 in the safe and security room by applying the B mode (special use), as shown in Figure 10, loosen the fixing screw 48 and the adjustment screw 50, solenoid 40 ) And bracket (46) move forward.

After the bracket 46 is in close contact with the rear wall of the case 10, the adjustment screw 50 is moved to the B mode side and fastened to the bracket 46, and then the fixing screw 48 is formed on the rear wall It is coupled to the hole and fastened to the bracket (46).

Therefore, the solenoid 40 is in an advanced state, and the support plate 44 is located at the bottom of the arm 18, so that the blade 20 (see FIG. 3) cannot be lowered, which causes the striker 6 (See Fig. 1) cannot escape the rocker 16 (see Fig. 3) so that the door 8 (see Fig. 1) cannot be opened arbitrarily in a closed state.

An operation state when the door 8 is to be opened in the above state is described in the flowchart of FIG. 12 as follows.

First, it is determined whether the switch 54 is turned on by the control unit 56 (see FIG. 3).

As described above, when the switch 54 is turned on, current is supplied to turn on the switch 54 while the solenoid 40 operates.

If the switch 54 is in the on state after S11, the controller 56 turns on the alarm lamp 58 (S12).

In addition, if the switch 54 is not in the on state after S11, the controller 56 determines again whether the limit switch 36 is in the on state (S13).

As described above, when the limit switch 36 is turned on, the striker 6 (see FIG. 1) is separated from the finger 28 of the latch 24 (see FIG. 3). The reversal force of the torsion springs 34 causes the reverse rotation, which causes the pressure 30 to press the bar 38 to turn on the limit switch 36.

If the limit switch 36 is in the on state after S13, the controller 56 turns on the alarm lamp 58.

In addition, if the limit switch 36 is not in the on state after S13, the controller 56 cuts off the current supply (S14).

When the current supply is interrupted as described above, the solenoid 40 stops the operation and reverses the rod 42 and the support plate 44 by the repulsive force of the provided spring. As a result, the support plate 44 is turned off as the switch 54 is turned off. ) Is located at the bottom of the arm (18).

The arm 18 of the rocker 16 is therefore not fixed by the support plate 44 located at the bottom and is fixed, so that the striker 6 (see Fig. 1) is latched 24 (see Fig. 3). In the state of pressing the finger 28 of the) will remain inside the locking device (4).

When the door 8 (see FIG. 1) is opened after S14, a current is supplied to operate the solenoid 40 (see FIG. 3).

When the current is supplied from the control unit 56 as described above, the solenoid 40 is operated to advance the rod 42 and at the same time to release the support plate 44 from the bottom of the arm 18 to turn on the switch 54. In this case, the arm 18 is in a state capable of freely rotating.

After the step S15, the controller 56 determines whether the switch 54 is in the on state (S16).

When the switch 54 is in the on state, the support plate 44 is separated from the bottom of the rod 42, so that the rocker 16 is freely rotated on the hinge shaft 14. (See Fig. 1) can be easily opened.

If the switch 54 (see FIG. 3) is not in the on state after S16, the controller 56 continuously transmits an operation command to the solenoid 40.

If the switch 54 is in the on state after S16, the controller 56 determines again whether the limit switch 36 is in the on state (S17).

When the limit switch 36 opens the door 8 (see Fig. 1) and the striker 6 is separated from the finger 28, the latch 24 is reversed by the repulsive force of the torsion spring 34. While the pressure 30 rotates, the bar 38 of the limit switch 36 is pressed, which causes the limit switch 36 to be turned on.

Therefore, the striker 6 (see FIG. 1) is separated from the case 10 while pushing down the inner surface of the blade 20 (see FIG. 3) as described above.

If the limit switch 36 is not in the on state after S17, the controller 56 waits. (S18)

If the limit switch 36 is not turned on, the striker 6 (see FIG. 1) is not in a state of being released from the finger 28 (see FIG. 3) (the door is closed). 36) stays off.

In addition, when the limit switch 36 is in the on state after S17, the controller 56 turns on the alarm light 58.

When the limit switch 36 is in an on state, the striker 6 (see FIG. 1) is separated from the finger 28 of the latch 24 (see FIG. 3), and the door 8 (see FIG. 1) is opened. The controller 56 (see Fig. 3) turns on the alarm lamp 58 as it is determined.

As described above, whether or not the door 8 (see Fig. 1) is opened or closed is determined by the limit switch 36 (see Fig. 3), and by the switch 54, the door 8 (see Fig. 1). It is determined whether the opening and closing of the.

The present invention supplies and cuts off the current through the control unit in the situation room to control the entrance and exit, and can check whether the door is opened or closed through the limit switch and the switch. It works.

The other effect is to cut off the current in order to keep the door fixed in the closed state, and to open or close the door by supplying the current to open the door. Can improve the practicality.
