For example, it is revealed that the applicant of the present invention can install the door lock device included in the inventions of the patent application Nos. 748712, 894176, 866997, and 848704 that have been pre- filed.

Referring to Figures 1 to 9 the working relationship of the present invention configured as described above is as follows.

First, the door closer 10 illustrated in FIGS. 1 to 4 is installed in the door frame 1 and the door 2 as shown in FIG. 5, and the case 11 is installed in the door frame 1 and the bracket 31 is provided. ) Is installed in the door (2), the sensor 4 is installed in the door frame (1) or the door (2), this sensor (4) should be installed both inside and outside of the door (2).

In this state, when power is supplied to the sensor 4 to detect that there is a person in the door 2 for several seconds, the solenoid 12 installed inside the door closer 10 is operated by the detected signal of the sensor. The plunger 13 installed at the distal end of the solenoid 12 is pulled out.

When the plunger 13 is pulled out in this way, the front end portion of the plunger 13 is hingedly connected to the lower support piece 19 on the lower side of the rotary housing 14 of FIG. The portion is hinged to the case 11 by the hinge pin 20 so that the rotating housing 14 is moved to the solenoid 12 side with the hinge pin 20 as the center of rotation.

Since the two-stage gear 23 is installed in the rotary housing 14 which rotates and moves toward the solenoid 12 as described above, the two-stage gear 23 also moves in the direction in which the solenoid 12 is installed and is close to the solenoid 12. The link driving gear 24 is installed inside the case 11 so that the upper gear 21 positioned above the two-stage gear 23 meshes with the link driving gear 24.

After that, the motor 26 installed in the motor mounting unit 17 of the rotary housing 14 is driven. The driving of the motor 26 is performed by the solenoid 12 according to a signal input to a control device (not shown). Afterwards, the motor 26 is driven after a set time of about 1 second. When the motor 26 is driven in this way, the driving screw 28 installed at the distal end of the motor 26 rotates and is engaged with the driving screw 28. The rotational force is transmitted to the lower gear 22 of the gear 23.

As described above, the rotational force transmitted to the lower gear 22 is transmitted to the link driving gear 24 meshed with the upper gear 21 through the upper gear 21 integrally formed with the lower gear 22 so that the link driving gear ( 24 is rotated, the rotary shaft 25 of the link driving gear 24 protrudes downward through the lower case (11b), the primary link 29 is installed at the lower end of the rotary shaft (25). Thus, the primary link 29 rotates in the same manner as the link drive gear 24.

The outer end of the primary link 29 that rotates as described above, the expansion link 30 is hingedly installed, the end of the expansion link 30 is hinged with the bracket 31 installed on the door (2). The connection is to open or close the door (2) automatically by pulling or pushing the expansion link 30 with the rotational force of the primary link (29).

Automatically opening or closing the door 2 from above is to open or close the door 2 automatically as the direction in which the motor 26 rotates is changed by a signal detected by the sensor. If you want to enter the room, open the door (2) and after the user enters the room, the sensor on the indoor side detects a person coming in to rotate the motor in the opposite direction to automatically close the door.

In this state, if the user stands within the rotation radius of the open door 2, the sensor detects the state so that the door 2 does not close, so that the door can be safely used.

If the door is not desired to open or close automatically, the circuit of the solenoid 12 and the motor 26 are cut off by manually switching the signal of the control device so that the plunger 13 of the solenoid 12 is configured. ) Is free.

The plunger 13 is in a free state in this state, because power is not supplied to the coil of the solenoid 12, and thus no pulling action is performed. As shown in FIG. It is built in, and the spring is in a state of pushing the plunger 13 outward.

Therefore, the rotary housing 14 is pushed to the left side in the drawing as shown in FIG. 2 so that the upper gear 21 of the two-stage gear 23 installed in the rotary housing 14 does not bite with the link drive gear 24. The upper gear 21 and the link driving gear 24 are separated from each other without interference.

In this state, when the user opens or closes the door 2, the force for opening and closing the door 2 is transmitted through the expansion link 30 and the primary link 29 from the bracket 31 connected to the door 2. The link drive gear 24 rotates, but the link drive gear 24 is idling because the upper gear 21 is not engaged in the link drive gear 24, so that the door 2 is generally operated. It can be opened and closed manually like the door.

Next, as shown in FIGS. 5 and 6, the door closer 10 and the door opening and closing device are installed inside the door 2 according to the present invention.

First, when a person in the room goes out through the door 2 or wants to enter the room from the outside of the door 2, the door must be opened and closed, and the signal for opening and closing the door is a door frame. The link drive gear 24 is operated by operating the solenoid 12 and the motor 26 inside the door closer 10 by the signal system inputted to the control device according to the signals of the sensors 4 installed on the inner and outer surfaces of (1). The primary link 29, one end of which is installed on the rotating shaft 25 of the) is rotated to open or close the door (2).

In such a situation, when a signal for opening the door is transmitted to the door closer 10, a series of processes in which the door closer 10 is operated (the solenoid 12 and the motor 26 sequentially rotate according to a signal detected by the sensor). It rotates the two-stage gear 23 and the link driving gear 24 by the operation of the motor and operating the primary link 29, the expansion link 30, and the bracket 31, the door ( The bracket 31 combined with 2) is pulled as shown in "a" of FIG.

At this time, the bracket 31 is installed in the horizontal slider 43 of the actuator 40 installed in the door 2 as shown in Figure 6 and 7, the horizontal slider 43 is the concave body 42 It is a state which can move by the predetermined length horizontally in the long hole 42b and the through-hole 42a formed in the inside.

And, between the middle spring hanger 46 and the left spring hanger 47, while the middle spring hanger 46 and the left and right spring hangers 47 and 48 are respectively provided on both sides of the frame 41, A spring 49 is elastically installed between the intermediate spring hanger 46 and the right spring hanger 48 so that the bracket 31 is located at the middle of the long hole 42b and horizontally the same as the horizontal slider 43. The hinge pin 62 inserted into the long hole 51 formed at the outer end of the rod 5 installed at the left end of the drawing pulley 45 is also located in the middle of the long hole 51. .

The bracket 31 is located in the middle of the long hole (42b) and the hinge pin 62 is also located in the middle of the long hole (51) is the initial state that the force pushing or pulling on the bracket (31).

In this state, when the horizontal slider 43 in which the bracket 31 is installed by the expansion link 30 is pulled to the right as shown in FIG. 7 from the inside of the long hole 42b, as shown in FIG. 6. The hinge pin 62 of the primary lever 61 installed on the rotating rod 6 is located in the middle of the long hole 51 of the rod 5, so that the bracket 31 including the rod 5 by the “b” interval is provided. This can be pulled in the " a " direction because the driving force of the motor 26 that pulls the bracket 31 is stronger than the elasticity of both springs 49.

Since the force for pulling the bracket 31 is stronger than the elasticity of both springs 49, the rod 5 is pulled to the right by the force to which the bracket 31 is pulled to the right, and the left inner surface of the long hole 51 is formed. The left side of the hinge pin 62 is brought into contact with each other, and the hinge pin 62 engaged to the left inner surface of the long hole 51 is pulled by the force that the rod 5 is pulled to the right. The distal end of the primary lever 61 provided with 62 is fixed to the rotary rod 6 so that the rotary rod 6 rotates counterclockwise as shown by " c "

As the rotating rod 6 rotates in the counterclockwise direction, as shown in FIG. 5, the auxiliary lock lever 63 connected to the auxiliary lock 7 and the main lock lever 64 connected to the door lock device 9 are also shown. Since the fixed end is fixedly coupled to the rotary rod 6, the secondary locking lever 63 and the main locking lever 64, as well as the upper primary lever 61, rotate in the same counterclockwise direction.

As described above, when the auxiliary locking lever 63 and the main locking lever 64 rotate counterclockwise, the free end of the auxiliary locking lever 63 and the after the auxiliary locking device 7 are rotated in the counterclockwise direction. By pulling the connecting rod 71 hingedly connected between the ends in the direction of "d", the sub lock 7 escapes from the lock hole 1a formed in the door frame 1 to lock the sub lock 7. Is released, the lock 91 of the door lock device 9 is locked by the connecting rod 92 connected between the door lock device 9 and the main lock lever 64 also in the case of the main lock lever (64). The door lock device 9 is released from the hole 1a.

Even in this state, the motor 26 continues to rotate, and as shown in FIGS. 6 and 7, the bracket 31 is continuously pulled in the right direction (a), in which case the primary lever 61 is no longer able to rotate. The hinge pin 62 is rotated counterclockwise and the hinge pin 62 is pulled to the right so that the hinge pin 62 of the primary lever 61 can no longer be pulled to the left inner surface of the long hole 51. The part is jammed.

Even in this state, the pulling force of the bracket 31 continues to act, and as described above, the auxiliary lock 7 and the door lock device 9 are unlocked, respectively, so that the door 2 has a bracket 31. The expansion link (30) connected to the will be opened in the pulling direction. At this time, the door 2 is hingedly installed on the door frame 1 by the hinge 3 so that the door 2 is opened in a hinged manner.

When the door 2 is opened and a person passes through the doorway, the sensor detects that the person passes through the doorway and stops the rotation of the motor 26. As a result, the door 2 remains open. Since the pulling force for pulling the bracket 31 to the right by the motor 26 is stopped, the bracket 31 which has been pulled to the right is pulled by the elasticity of the spring 49 caught by the left spring hanger 47. In the middle of 42a).

As described above, the bracket 31 is in the middle of the long hole 42a as shown in (b) of FIG. 7. The two springs 49 having the same elasticity in the state in which the intermediate spring hanger 46 is in the middle. ) Is hung on the left spring hanger 47 and the right spring hanger 48, respectively, so that both springs 49 have the same pulling force and are installed on the right side of the bracket 31 and the rear of the bracket 31 which were on the right side. Pull 45 is to be in the middle of the long hole (42a).

In this state, the motor rotates in the reverse direction after a few seconds according to the input signal of the control device to close the door 2, in which case the primary link 29 and the expansion link 30 as the motor 26 rotates in the reverse direction. ) Is pushed in the opposite direction as when opening the door (2).

In this state, the horizontal slider 43 in which the bracket 31 is installed is pushed as shown by "e" in FIG. 7 inside the long hole 42b by the operation of the elastic link 30, and the rear of the urine body 42. As a result, the pull table 45 provided by the connecting bolt 44 and the rod 5 installed at the end of the pull table 45 are also pushed in the same direction as the horizontal slider 43.

As such, the horizontal slider 43 including the connecting bolt 44, the pulling table 45, and the rod 5 are pushed to the left side (“e” direction), and the right inner surface of the long hole 51 has the hinge pin 62. By pushing the right side, the fixed end of the primary lever 61 in which the hinge pin 62 is installed is installed on the rotary rod 6 so that the rotary rod 6 rotates clockwise as shown in "f" of FIG.

As the rotary bar 6 rotates in the clockwise direction, as shown in FIG. 5, the auxiliary lock lever 63 connected to the auxiliary lock 7 and the main lock lever 64 connected to the door lock device 9 are also rotated ( 6) is fixedly coupled to the upper end, the upper primary lever 61, the auxiliary locking lever 63 and the main locking lever 64 is rotated in the same clockwise direction.

As described above, when the primary lever 61 and the auxiliary locking lever 63 and the main locking lever 64 rotate clockwise, between the free end of the auxiliary locking lever 63 and the rear end of the auxiliary locking device 7. The auxiliary lock 7 is inserted into the locking hole 1a formed in the door frame 1 by pushing the connecting rod 71 connected in a hinged manner in the "g" direction, and the locking operation is performed, and the main locking lever ( Also in the case of 64, the lock 91 of the door lock device 9 is inserted into the lock hole 1a by the connecting rod 92 connected between the door lock device 9 and the main lock lever 64 so that the door lock device (9) is locked.

Next, a description will be given when the door is opened and closed manually using the door closer. In this case, as shown in FIG. 2, since the power is not supplied to the solenoid 12, the spring 12a installed inside the solenoid 12 is plunger 13.
