Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a first embodiment of an occupancy confirmation locking device according to the present invention.
[First Embodiment]
The occupancy confirmation locking device 11 according to the present embodiment is roughly divided into a locking detection unit 13, a time measuring unit 15, a notification unit 17, and a control unit 19. The lock detection unit 13 is attached to an indoor expression member 25 of an existing lock device 23 as a lock device provided in the opening / closing body 21. The opening / closing body 21 is, for example, a door 27. In addition, the opening / closing body 21 may be a sliding door. The existing lock device 23 can be, for example, an exposure type locking / unlocking device or the like in which the lock box 29 is exposed and attached to the indoor surface 31 of the door 27. In this case, the indoor expression member 25 is a lock box 29. A dead bolt 33, a latch bolt 35, a thumb turn 39 as an indoor operation member 37, a lever handle 41 as an opening / closing operation member, and the like are attached to the lock box 29. When the lock box 29 is installed in the door 27, the indoor display member 25 may be a seat plate portion exposed on the indoor surface 31 of the door 27, or only the thumb turn 39 is displayed on the indoor surface 31. As long as it is configured to be used, the color portion of the thumb turn 39 may be used.

  The lock detection unit 13 detects a lock operation from the indoor side of the existing lock device 23. That is, the lock detection unit 13 includes an operation detection member 43 that detects the operation of the indoor side operation member 37. The operation detection member 43 can be a reed switch 45 that is activated by the operation of the thumb turn 39 when the lock detection unit 13 is attached to the lock box 29. In addition, the operation detection member 43 may be a mechanical switch that falls down by the operation of the thumb turn 39, such as a micro switch. The operation detection member 43 may be a touch sensor and may be turned on when the thumb turn 39 is operated from the room. Further, the operation detection member 43 may be a surface switch, such as a button, provided on the surface of the thumb turn 39, and may be turned on by the operation (pinch) of the thumb turn 39.

  Since the lock detection unit 13 includes the operation detection member 43, when the lock detection unit 13 is attached to the existing lock device 23, the operation detection member 43 detects the lock operation of the thumbturn 39 provided in the existing lock device 23. Is done. By providing the operation detection member 43 in the lock detection unit 13, only the operation of the thumb turn 39 can be detected. That is, only the locking operation from the indoor side is detected and the reed switch 45 is turned on / off.

  The lock detection unit 13 is provided with a time measuring means 15. The time measuring means 15 starts measuring time in response to the detection of the locking detection unit 13. The detection of the lock detection unit 13 is performed by an on / off signal of the reed switch 45. The time measuring means 15 outputs a time lapse signal after a predetermined time has elapsed from the start of measurement. The time measuring means 15 can be a timer circuit provided in the control means 19 described later.

  An informing means 17 is provided in an outdoor building part. The notification unit 17 may be an outdoor unit 51 having a light emitting display unit 49 such as an LED 47. In addition, the notification means 17 may perform notification by sound. The outdoor building portion can be an outdoor surface 53 of the door 27 and an escation 57 (see FIG. 3) which is an outdoor expression member 55 (see FIG. 3) of the existing lock device 23. In the outdoor unit 51, a notifying unit side connector 59 is connected to the derived electric wire end, and this notifying unit side connector 59 is coupled to a locking detection unit side connector 63 attached to the electric wire end derived from the locking detection unit 13. And is electrically connected to the locking detector 13.

  The lock detection unit 13 includes a control unit 19 connected to the reed switch 45 and the outdoor unit 51. The control means 19 includes a circuit board 65 on which a CPU is mounted, and a power source unit such as a battery. Note that the lock detection unit 13 may use a commercial power supply in addition to the battery 67. The circuit board 65 incorporates a timer circuit which is the time measuring means 15 described above. The circuit board 65 incorporates a control circuit that drives the notification means 17 by inputting a time lapse signal. That is, when a predetermined time elapses, the light emission display unit 49 of the outdoor unit 51 is turned on or blinked to notify.

  A timer changeover switch 69 is provided on the circuit board 65. The timer changeover switch 69 can variably set the predetermined time of the time measuring means 15. The timer changeover switch 69 can selectively switch a predetermined time such as 36 hours or 48 hours, for example. When the predetermined time of the time measuring means 15 is changed and set, the time from when the time measuring means 15 starts measuring time until the time elapse signal is output can be changed short or long. Thereby, the time from when the last locking operation from the indoor side is performed to when the notification means 17 is driven can be set according to the individual difference of the person being monitored.

  In addition, the lock detection unit 13 is provided with a status display LED 71 for checking the occupants. The state display LED 71 includes, for example, a red LED 73 and a green LED 75 controlled by the control means 19. Various states can be displayed by lighting the red LED 73 and the green LED 75 separately. For example, the battery replacement can be displayed by blinking the green LED 75, or the indoor lock confirmation can be displayed.

Next, the operation of the occupancy confirmation locking device 11 having the above configuration will be described.
FIG. 2 is a flowchart for explaining the operation procedure of the occupancy confirmation locking device 11 shown in FIG.
In the occupancy confirmation locking device 11, when the control means 19 is driven, it is determined by the control means 19 whether or not locking is performed indoors (S1). When the lock operation signal of the thumb turn 39 from the reed switch 45 is detected, the control means 19 determines the presence (S2). The control means 19 starts the initialization and counting of the time measuring means 15 using the detection of the locking operation signal as a trigger. In other words, on the indoor side, when the thumb turn 39 is locked, the occupancy mode is set, and it is detected that "the door is locked by the thumb turn 39 in the room", and the timer is started (S3). The control means 19 determines the unlock signal from the reed switch 45 simultaneously with the timer count (S4). That is, the count is continued if the unlock signal from the reed switch 45 is not detected.

The control means 19 determines the elapse of a predetermined time (S5), determines that an abnormality has occurred when the timer count reaches the predetermined time (S6), and drives the light emission display section 49 of the outdoor unit 51 to emit light (S7). ).
Note that the control means 19 may have an abnormality output unit (terminal) that outputs the abnormality occurrence as a signal to the outside. Thereby, it is possible to notify the monitoring device or the like of the management room provided in the apartment house or the like (S8).

  Thus, in the occupancy confirmation locking device 11, the lock detection unit 13 as a main component is attached to the indoor display member 25 of the existing lock device 23, and no other mounting space or other large-scale device is required. Become. Further, since the lock detection unit 13 detects only the lock operation from the indoor side of the existing lock device 23, for example, when going out, a release operation for canceling the detection operation becomes unnecessary.

  According to the occupancy confirmation locking device 11 according to the first embodiment, the occupancy confirmation locking device 11 can be completed only by the locking device, can be configured at low cost, can be easily retrofitted, and is easy as a device for confirming the occupancy state. In addition, it is possible to prevent misreporting in the absence without a release operation.

Further, the occupancy confirmation locking device 11 can be configured as an option of the existing locking device 23. In other words, it can be easily retrofitted to the existing locking device on the door, and may be assembled as needed when it is necessary from the state of spending a normal life.
According to such an occupancy confirmation upper layer 11, monitoring is started by a locking operation that is always performed when entering the room, so that the abnormal change in the confined state is not continued, leading to early detection.
In addition, since it is possible to check the presence of the room and not detect it by the locking operation when going out, it is possible to check from outside the room that the user is not in the room, and unnecessary monitoring is eliminated.
And since it will alert | report to the exterior rapidly after progress of the set predetermined time, it will reduce that it is too late.

[Second Embodiment]
Next, the occupancy confirmation locking device 77 according to the second embodiment of the present invention will be described.

The existing thumb turn 39 is actually invisible.

  On the other hand, on the outdoor surface 53 of the door 27, a light emitting plate 93 which is a notification means 91 is provided. The light emitting plate 93 is sandwiched and attached between the escation 57 that is the outdoor expression member 55 of the existing lock device 23 and the outdoor surface 53. The light emitting plate 93 may be either one that emits light as a whole or one provided with LEDs 47.

  Also in this embodiment, the indoor side operation member 95 is the thumb turn 39. The thumb turn 39 actually disappears when the thumb turn cover 89 covers it. The thumb turn cover 89 that is the operation detecting member 81 detects only the locking operation by the thumb turn 39, excluding the detection of the locking operation by the cylinder lock 97 of the existing locking device 23. The thumb turn cover 89 includes a selection detection structure 99 for this purpose.

  As shown in FIG. 4, the selection detection structure 99 includes a magnet ring 101 mounted on the outer periphery of the thumb turn 39 and the thumb turn cover 89 that covers the thumb turn 39. A magnet 103 detected by a reed switch 45 is fixed to a part of the circumferential direction of the magnet ring 101. In the magnet ring 101, the reed switch 45 reacts when the magnet 103 comes directly above. This makes it possible to detect locking from the indoor side.

  The thumb turn cover 89 includes a flange portion 105 and a tube portion 107. The flange portion 105 is formed with a notch 109 having a predetermined length in the circumferential direction in which the magnet 103 of the magnet ring 101 is movable. Further, the cylindrical portion 107 has a dharma hole 111 through which the thumb turn 39 is inserted. The dharma hole 111 has a shape in which fan-shaped spaces are connected point-symmetrically. As shown in FIG. 4 (b), the thumb turn cover 89 may have a Dalma-shaped thumb turn with the Dalma hole 111 as a lid, or a flat plate as shown in FIG. 4 (c). A thumb turn cover 89 having a pick portion 88 similar to the thumb turn having the shape pick structure may be covered with the dharma shaped portion. The magnet ring 101 is mounted on the thumb turn 39 of the existing lock device 23 and the thumb turn cover 89 is put on the thumb turn 39, so that the magnet ring 101 and the thumb turn cover 89 are relatively rotated within a range in which the magnet 103 can be moved by the notch 109. It becomes possible.

  As shown in FIG. 5, the thumb turn cover 89 that is the operation detection member 81 includes a detection exclusion space 113 that moves the thumb turn 39 inward. That is, it has a play range θ1. The play range θ1 is preferably about 30 °, for example. The range of the notch 109, that is, the sensor range θ2, is preferably about 45 °. The attachment range θ3 of the magnet 103 is preferably about 15 °.

Next, the operation of the occupancy confirmation locking device 77 will be described.
FIG. 6 is an operation explanatory diagram showing the respective operations when the occupancy confirmation locking device 77 shown in FIG. 3 is a left hand as (a), (b), (c), and (d), and FIG. 7 is shown in FIG. It is operation | movement explanatory drawing which represented each operation | movement in case the occupancy confirmation lock apparatus 77 is a right hand as (a) (b) (c) (d).
In the case of a left hand in which the dead bolt 33 moves forward and backward on the left side, as shown in FIG. . As a result, the magnet 103 moved by the notch 109 becomes the detection position, and the magnet 103 is detected by the reed switch 45. In this state, in unlocking using the cylinder lock 97 from the outdoor side, the thumb turn cover 89 rotates together with the thumb turn 39 as shown in FIG.

  As shown in FIG. 6 (b), when the cylinder lock 97 is used for locking from the outdoor side, the magnet 103 is moved backward by the detection exclusion space 113 from the rotation of the thumb turn 39 that is rotated by the operation of the key. The magnet 103 does not reach the detection position of the reed switch 45 even in the locked state. As a result, the magnet 103 is not detected by the reed switch 45. In this state, in the unlocking using the cylinder lock 97 from the outdoor side, as shown in FIG. 6 (d), the thumb turn 39 rotates to 30 ° without hitting the thumb turn cover 89, and after 30 ° the thumb turn Turn the cover 89.

  As shown in FIG. 6C, when the thumb turn cover 89 is unlocked from the indoor side, the notch 109 moves the magnet 103 from the reed switch 45 at an angle of approximately 90 °, and the magnet 103 Not detected by switch 45. In this state, when locking from the indoor side, the thumb turn cover 89 rotates 30 °, and after 30 °, the thumb turn 39 is turned. In other words, the thumb turn 39 is accompanied by the thumb turn cover 89 with a delay. In the case of locking from the outdoor side, the thumb turn cover 89 rotates with the thumb turn 39 as shown in FIG.

  As shown in FIG. 6D, when the cylinder lock 97 is used to unlock from the outdoor side, the notch 109 moves the magnet 103 from the reed switch 45 at an angle of approximately 60 °, and the magnet 103 Not detected by switch 45. In this state, when locking from the indoor side, the thumb turn cover 89 rotates together with the thumb turn 39 as shown in FIG. Further, in the case of locking from the outdoor side, as shown in FIG. 6B, the thumb turn 39 does not hit the thumb turn cover 89 until 30 °, and the thumb turn cover 89 is rotated after 30 °.

In the case of the right hand, the operation is the same as that in FIG. 6 except that the rotation direction of the thumb turn 39 and thumb turn cover 89 is opposite to that in FIG. Therefore, in the case of the right hand, only the point will be described.
As shown in FIG. 7 (a), when the lock is made by an operation from the indoor side, the thumb turn cover 89 rotates 30 °, and the thumb turn 39 is rotated by 30 ° or more. As a result, the magnet 103 moved by the notch 109 becomes the detection position, and the magnet 103 is detected by the reed switch 45.

  As shown in FIG. 7B, when the cylinder lock 97 is used for locking from the outdoor side, the magnet 103 rotates rearward by the distance of the detection exclusion space 113 from the rotation of the thumb turn 39, and the locking is completed. Even in the state, the magnet 103 does not reach the detection position of the reed switch 45. As a result, the magnet 103 is not detected by the reed switch 45.

  As shown in FIG. 7C, when the thumb turn cover 89 is unlocked from the indoor side, the notch 109 moves the magnet 103 from the reed switch 45 at an angle of approximately 90 °, and the magnet 103 Not detected by switch 45.

  As shown in FIG. 7D, when the cylinder lock 97 is used to unlock from the outdoor side, the notch 109 moves the magnet 103 from the reed switch 45 at an angle of approximately 60 °, and the magnet 103 Not detected by switch 45.

  In this occupancy confirmation locking device 77, when the locking detection unit 79 is attached to the existing locking device 23, the operation detection member 81 is attached to the thumb turn 39. At this time, the operation detection member 81 is provided with the selection detection structure 99, so that the locking operation of the cylinder lock 97 is excluded from the detection. Thereby, only the locking operation of the thumb turn 39 from the indoor side can be detected.

  Further, when the operation detection member 81 is put on the thumb turn 39 and the cylinder lock 97 is unlocked, the detection exclusion space 113 avoids interference between the rotating thumb turn 39 and the operation detection member 81. In other words, the operation detection member 81 does not perform the detection operation depending on the locking operation of the cylinder lock 97. Thus, since the locking operation by the operation of the cylinder lock 97 from the outdoor side can be excluded from the detection, the lock detection unit 79 does not operate when going out and the false alarm output can be prevented when going out.

  According to the occupancy confirmation locking device 77 according to the second embodiment, it can be completed only by the locking device, can be configured at low cost, can be easily retrofitted, and prevents false notifications when there is no absence without a release operation. it can.

[Third Embodiment]
Next, the occupancy confirmation locking device 11 of the third embodiment according to the present invention will be described.
FIG. 8 is a perspective view of a third embodiment of the occupancy confirmation locking device 115 according to the present invention, and FIG. 9 is an exploded perspective view of the occupancy confirmation locking device 115 shown in FIG. Members identical to those shown in FIGS. 1 to 7 are assigned the same reference numerals and redundant description is omitted.
As shown in FIG. 8, the occupancy confirmation locking device 115 is attached to the indoor expression member 119 of the existing locking device 117. In this embodiment, the indoor exposed member 119 is a seat plate portion 121 exposed on the indoor surface 31 of the door 27.

  In the occupancy confirmation locking device 115, the lock detection unit 123 is attached to the existing locking device 117. The lock detection unit 123 includes a sensor unit 125. The sensor unit 125 is covered with a cover case 129 to which a battery cover 127 is detachably attached. A thumb turn cover 133 that is an operation detection member 131 is exposed and attached to the cover case 129. The thumb turn 39 is operated by operating the thumb turn cover 133. The existing thumb turn 39 is actually invisible.

  On the other hand, on the outdoor surface 53 of the door 27, for example, a light emitting plate 93 that is a notification means 91 similar to the notification means 91 shown in FIG. The light emitting plate 93 is sandwiched and attached between the escation 57 that is the outdoor expression member 55 of the existing lock device 117 and the outdoor surface 53.

  As shown in FIG. 9, the sensor unit 125 is attached to the existing lock device 117 via a base plate 135 fixed to the lock box 29. A battery box 137 that houses the battery 67 is fixed to the base plate 135. A back cover 139 is fixed to the base plate 135, and the back cover 139 holds a cover case 129. Inside the cover case 129, a thumb turn cover 133, a magnet ring 141, a lens unit 145 having a plurality of lens portions 143, and a control means 147 are provided. The control means 147 has a circuit board 149 on which a CPU, an LED 47 and a reed switch 45 are mounted. When the status display LED 71 is driven by the control means 147, the occupancy confirmation locking device 115 is configured such that light from the status display LED 71 has a different color (for example, red or green) to the outside of the cover case 129 via the lens unit 143. And the status is displayed.

  In the occupancy confirmation locking device 115 of this embodiment, two reed switches 45 are provided adjacent to each other. Further, the thumb turn cover 133 is formed with notches 109 at both ends in the diameter direction. The magnet ring 141 is provided with two magnets 103 at both ends in the diameter direction, for a total of four. By making the reed switch 45 and the magnet 103 face each other, the detection range of the magnet 103, that is, the operation detection range of the thumb turn 39 is expanded. This is because the locking rotation is biased by the biasing spring immediately before the end of the locking rotation as a mechanical characteristic of the existing locking device 117. That is, even if the rotation operation of the thumb turn 39 is stopped immediately before completion by this biasing, the locking is mechanically completed (turns around). The error between the operation rotation and the lock completion is eliminated by expanding the operation detection range of the thumb turn 39 by using two magnets 103. Further, although not shown in the figure, another magnet 103 that can detect overshoot of the thumb turn 39 may be added to the operation rotation side.

  It should be noted that the magnet 103 provided in two pairs at both ends in the diameter direction of the magnet ring 141 and the pair of notches 109 formed in the thumb-turn cover 133 include the pair of magnets 103 and the notches 109 as described above. The other pair of magnets 103 and the notch 109 are connected to the reed switch 45 when the magnet ring 141 and the thumb turn cover 133 are attached to the thumb turn 39. It is provided as a reserve so as to be compatible, that is, it is possible to narrow the mounting range within 180 °, which is half of the outer periphery 360 °, and improve the ease of mounting.

Next, the operation of the occupancy confirmation locking device 115 will be described.
FIG. 10 is an operation explanatory view showing each operation of the occupancy confirmation locking device 115 shown in FIG. 8 by (a), (b) and (c).
In this occupancy confirmation locking device 115, when the lock is applied from the outdoor side, the thumb turn cover 133 is rotated by the thumb turn 39. As a result, the reed switch 45 does not react and is not detected.

  When locked from the room side, the thumb turn 39 is rotated by the rotation operation of the thumb turn cover 133, and when the state shown in FIG. 10B is reached, the reed switch 45 reacts to detect. As a result, the control means 147 drives one of the LEDs 47 and 73 to display that it is operating, that is, being in the room.

  In addition, when locking from the indoor side, as shown in FIG. 10 (c), when the thumb turn 39 rotates about 70 ° to 80 °, even if the thumb turn 39 is locked by the biasing spring, the magnet 103 on the leading side in the rotational direction is , The adjacent reed switch 45 is reached, and the reed switch 45 reacts. As a result, a malfunction in which locking is not detected is prevented, and the reliability of the detection state is improved.

  According to the occupancy confirmation locking device 115 according to the third embodiment, it can be completed only by the locking device, can be configured at a low cost, can be easily retrofitted, and is reliable with two reed switches 45. It is possible to improve and prevent misreporting in the absence without a release operation.
