The main deadbolt 5a is urged and held in the advance direction.

The transmitting means 40 is non-contacting with respect to the receiving means 42, that is, separate from the casing 51 and sends a locking or unlocking signal to the receiving means 42 without contacting from the outside of the door 52. It is. In the present embodiment, the mobile phone 40 is as shown in FIG. An information signal such as an ID code or the like serving as an unlock signal or a lock signal is transmitted to the receiving antenna 42 in a non-contact manner by each key such as a numeric keypad provided in the mobile phone 40.
The transmission means 40 may be other than a configuration using a portable telephone, and may be a portable device such as a transmitter such as an IC card storing an ID code or a remote control device having a numeric keypad or a switch. Other configurations may be used as long as the ID code can be transmitted to the terminal 42 without contact. In such a configuration, the battery is built in. However, since the receiving unit is configured to use a commercial power supply, the battery may be configured without a power source. By arranging the excitation circuit by incorporating the coil, when the transmitter is brought close to the receiving unit side, it is excited and can transmit an ID code or the like, and control can be performed by receiving this.

  As shown in FIGS. 3 and 4, the door 52 of the casing 51 provided with the door locking device of the present invention is structured to have an edge portion 58 that further extends to the free end 53 of the door. A concave groove 56 is formed on the side of the door inner surface 52a at the vertical side edge. And the front-end | tip 5aa of the above-mentioned dead volt | bolt 5 (5a) protrudes in this recessed groove part 56. FIG. A frame body 59 that fits into the recessed groove portion 56 is provided on the opening 60 side of the housing 51, and a tip 5aa of the dead bolt 5 (5 a) is inserted into a locking hole (not shown) formed in the frame body 59. Is configured to enter. With such a configuration, the free end 53 side of the door 52 is fitted to the edge of the opening portion 60 of the housing 51, and the door free end 53 and the housing opening portion 60 are connected to each other from the outside of the housing 51. The deadbolt 5 (5a) cannot be visually recognized between the gaps, and it is impossible to perform an illegal act such as inserting a tool or the like into the gap between the door 52 and the casing 51. . Further, the door 52 is provided with the above-described mechanism portions on the inner surface 52a side of the door 52, and the entire door inner surface 52a is covered with a cover plate 57 that covers these portions (see FIG. 2).

  Further, the lock device 1 of the present embodiment can be replaced with the lock device of the existing automatic settlement machine 50, and the size and shape of the lock box 12, the position of the fixing screw, and the forward and backward movement of the regulating portion 14 of the slider 13. The length, etc., is equivalent to a locking device with a cylinder lock as described in the prior art, and can be replaced during maintenance, etc. It can be replaced with a lock device to improve security and operability.

Next, the operation of the door locking device having the above-described configuration will be described.
When the door 52 is closed and locked, the dead bolts 5a, 5b and 5c are advanced from the periphery of the door 52 as shown in FIG. In addition, the main deadbolt 5a is prevented from retreating, and the stopper 16 of the actuator 15 is advanced to prevent the slider 13 from retreating.
In this state, even if the thumb turn 3 is to be rotated, the stopper 16 prevents the slider 13 from moving backward, so that the rotating operation is not performed and the restricting portion 14 of the slider 13 is moved backward. There is nothing.

  Further, even if the door opening handle 2 is operated, the main dead bolt 5a does not move backward, and the sub dead bolts 5b and 5c respectively connected to the link piece 6 do not move backward. The main deadbolt 5a is in a contact state with the buffer portion 30 applied with an urging force from the rear, and the advanced state of the main deadbolt 5a is always urged. That is, when the door opening handle 2 is operated in spite of being locked, the main dead bolt 5a linked to the door opening handle 2 via the link piece 6 is urged in the advancing direction. Thus, the door opening handle 2 is maintained in that state, and the advanced restricting portion 14 and the dead bolt 5 (5a) do not interfere with each other.

The door 52 is opened by using a mobile phone 40 as a transmission means possessed by the administrator and inputting and transmitting a specific key operation, for example, a numeric keypad, for example, a unique ID code.
The transmitted ID code is received by the receiving unit 42 as an unlock signal, and the receiving unit 42 sends a signal to the control unit 41. In the control unit 41, the comparison calculation means 44 makes a comparison judgment with a unique ID code stored in advance in the storage means 43 to determine whether the transmitted ID code is correct. When the ID code is correct, an unlock signal as an operation signal is sent to the actuator 15.

When receiving the unlock signal, the actuator 15 operates the operating shaft 27 to retract the stopper 16 as shown in FIG. When the stopper 16 is retracted, the projecting piece 28 comes into contact with the micro switch 29, thereby notifying the outside that the unlocking has been performed, for example, by a display means such as light or sound.
When the stopper 16 moves backward, the slider 13 can move backward, that is, the thumb turn 3 can be rotated.

  When the thumb turn 3 is turned, the interlocking rod 18 slides the slider 13 downward as shown in FIG. Then, as shown in FIG. 9, when the thumb turn 3 is rotated about 90 ° in the present embodiment, the interlocking rod 18 comes into contact with the lower oblique side portion 25b of the slider 13, and the descent stops. That is, the restricting portion 14 of the slider 13 is retracted into the lock box 12, that is, retracted from the movement locus of the dead bolt 5 (5a). Thereby, the dead bolt 5 (5a) can be retracted.

  Next, after confirming that the thumb turn 3 has rotated 90 °, the door opening handle 2 is rotated. As the door opening handle 2 is turned, the link piece 6 linked to the door opening handle 2 swings. As a result, as shown in FIG. 4, the main dead bolt 5a, the upper sub dead bolt 5b, Each of the lower secondary dead bolts 5c slides and the front ends 5aa, 5ba, 5ca retreat from the peripheral edge of the door 52. During this operation, the buffer 30 that is in contact with the rear end 5ab of the main dead bolt 5a swings as shown in FIG. 10 as the main dead bolt 5a moves backward, and the main dead bolt 5a moves. There is no hindrance to the movement from the trajectory. Further, the main dead bolt 5a and the sub dead bolts 5b and 5c advance or retreat at the same time.

  Thereby, the door 52 can be opened, and the door 52 is opened by pulling the opening handle 2.

  When the door 52 is locked, the above opening procedure is reversed. After the door 52 is closed, the opening handle 2 is rotated to advance the dead bolts 5a, 5b, 5c, and then the thumb turn 3 is turned. The control unit 14 is moved to project the restricting portion 14 of the slider 13, and finally, a unique ID code serving as a locking signal is transmitted by the portable telephone 40 which is a transmitting means, so that the stopper 16 is advanced and locked.

  In addition, it is good also as what is comprised by what is called auto-locking which act | operates the actuator 15 automatically by making a door close operation and making it recognize with the sensor etc. that operation by the thumb turn 3 was carried out. 40 can be used only when unlocking. Moreover, it is good also as notifying by the above indicating means that this locking was completed.

  Therefore, according to the door locking device 1 described above, in order to open the door 52, the unlocking operation is performed by actuating the actuator 15 which is an electrical configuration, and the door 52 is closed and locked. The actuator 15 is operated to perform the locking operation. For this reason, it is not necessary to use a key for unlocking and unlocking the door 52, and therefore it is not necessary to provide a keyhole on the outdoor surface of the door 52. It becomes possible to prevent operation. Furthermore, since the door 52 is locked and unlocked using the transmission means 40 having a non-contact configuration, it is possible to prevent a person other than the administrator from opening the door easily.

  In addition, since the buffer portion 30 is provided, the dead bolt 5 can be used against an unauthorized operation to operate the door opening handle 2 to move the dead bolt 5 (5a) when the door is not unlocked. The urging force to push back (5a) always works, preventing the slider 13 from interfering with the restricting portion 14, and damaging the restricting portion 14 and the moving piece 9 of the dead bolt 5 (5a). It is hard to get up. In addition, the dead bolt 5 (5a) is kept in the advanced state by the biasing means 46 provided in the buffer portion 30, so that the locked state of the door 52 is maintained.

  Furthermore, by configuring the transmission means with the portable telephone 40, a unique ID code corresponding to the target automatic checkout machine 50 can be transmitted by a key such as a numeric keypad provided in the portable telephone 40, for example. It becomes possible. From this, it is possible to perform an operation of locking and unlocking each of the plurality of automatic settlement machines 50 by transmitting ID codes corresponding to them, that is, the automatic settlement machines 50 as in the past. It is no longer necessary to have the same number of keys, and if only one mobile phone 40 is held, each automatic settlement machine 50 can be unlocked and locked, and management is simplified.
