The present invention relates to an electric lock device.
In a retrofitted electronic lock device to be attached to an existing door of a building, self-lock control for preventing unlock is executed. That is, the electronic lock device automatically executes locking when a certain period of time elapses after being locked to unlocked, or when the door is from an open state to a close state. However, when going out for a short time for chores such as waste disposal, the user often manually unlocks the electronic lock device by operating a thumb turn on the indoor side without carrying a key (including not only a cylinder lock but also a portable machine and a smartphone) and goes out with the door opened. In this case, if the user closes the door as it is, the user is locked out to the outdoors as a result of locking by self-lock control.
Patent Document 1 discloses an electronic lock device that can temporarily stop self-lock control where necessary such as when going out for a short time. Specifically, in order to temporarily stop self-lock control, it is necessary to operate an operation knob to an unlock position a plurality of times within a certain period of time.
Self-lock temporary stop control in the electronic lock device of Patent Document 1 has the following problem. First, in this electronic lock device, it is necessary to operate the operation knob to the unlock position a plurality of times for the self-lock temporary stop control. On the other hand, when the operation knob is operated to a lock position after the self-lock temporary stop control, the electronic lock device is switched to the self-lock control. Therefore, even if the operation knob is operated a plurality of times between the lock position and the unlock position for the self-lock temporary stop control, if the operation knob is erroneously ended up at the lock position, switching to the self-lock temporary stop control is not performed. That is, there is a possibility that switching to the self-lock temporary stop control is not executed by an erroneous operation contrary to the user's original intention. Next, in order to set the operation knob to the unlock position a plurality of times within a certain period of time for the self-lock temporary stop control, the user needs to remember how many times he/she has operated the knob. In this respect, a complicated operation is required.
An object of the present invention is to reduce possibility of an erroneous operation and improve operability in self-lock temporary stop control of an electronic lock device.
A first aspect of the present invention provides an electronic lock device including: a body attached to a door including a lock/unlock portion for a switching operation between locking and unlocking; a coupling portion mechanically coupled to the lock/unlock portion; a manual operation portion that is provided in the body, operates integrally with the coupling portion, and is manually operable among a lock position where the door is locked by the lock/unlock portion via the coupling portion and an unlock position where the door is unlocked by the lock/unlock portion via the coupling portion; a position detection portion that detects which of the lock position and the unlock position the manual operation portion is positioned in; a drive portion that drives the coupling portion to cause the lock/unlock portion to lock and unlock the door; and a control portion that can execute self-lock control in which the driving unit drives the coupling portion to cause the lock/unlock portion to lock the door and self-lock temporary stop control of temporarily stop the self-lock control when a predetermined time elapses after the position detection portion detects that the lock/unlock portion has changed from the lock position to the unlock position, in which the control portion switches from the self-lock control to the self-lock temporary stop control upon detecting that the manual operation portion is operated from the lock position to the unlock position within a first set time and is operated to the lock position again based on an input from the position detection portion.
A second aspect of the present invention provides an electronic lock device including: a body attached to a door including a lock/unlock portion for a switching operation between locking and unlocking; a coupling portion mechanically coupled to the lock/unlock portion; a manual operation portion that is provided in the body; operates integrally with the coupling portion, and is manually operable among a lock position where the door is locked by the lock/unlock portion via the coupling portion, an unlock position where the door is unlocked by the lock/unlock portion via the coupling portion, and a neutral position between the lock position and the unlock position; a position detection portion that detects which of the lock position, the unlock position, and a neutral position the manual operation portion is positioned in; a drive portion that drives the coupling portion to cause the lock/unlock portion to lock and unlock the door; and a control portion that can execute self-lock control in which the driving unit drives the coupling portion to cause the lock/unlock portion to lock the door and self-lock temporary stop control of temporarily stopping the self-lock control when a predetermined time elapses after the position detection portion detects that the lock/unlock portion has changed from the lock position to the unlock position, in which the control portion switches from the self-lock control to the self-lock temporary stop control upon detecting that the manual operation portion is operated from the lock position to the neutral position within a second set time and is operated to the lock position again based on an input from the position detection portion.
According to the first aspect of the present invention, the manual operation portion is operated from the lock position to the unlock position within a certain period of time (within the first set time), and is operated to the lock position again, whereby the self-lock control can be switched to the self-lock temporary stop control. According to the second aspect of the present invention, the manual operation portion is operated from the lock position to the neutral position within a certain period of time (within the second set time), and is operated to the lock position again, whereby the self-lock control can be switched to the self-lock temporary stop control.
Switching to the self-lock temporary stop control is performed only by returning the manual operation portion to the original lock position within a certain period of time from the position at the time of operation start for switching to the self-lock temporary stop control, that is, another position from the lock position (the unlocking position in the first aspect and the neutral position in the second aspect). Therefore, it is possible to prevent the user from further operating the manual operation portion contrary to the original intention, thereby preventing the switching to the self-lock temporary stop control from being performed. That is, it is possible to reduce the possibility that the user erroneously operates the manual operation portion contrary to the original intention.
In both the first and second aspects, the self-lock control can be switched to the self-lock temporary stop control only by operating the manual operation portion twice, and therefore the user does not need to memorize the number of times of operation of three or more times of the manual operation portion. In this respect, in both the first and second aspects, it is possible to improve the operability of operation of the manual operation portion required for switching to the self-lock temporary stop control.
A third aspect of the present invention provides an electronic lock device including: a body attached to a door including a lock/unlock portion for a switching operation between locking and unlocking; a coupling portion mechanically coupled to the lock/unlock portion; a manual operation portion that is provided in the body; operates integrally with the coupling portion, and is manually operable among a lock position where the door is locked by the lock/unlock portion via the coupling portion, an unlock position where the door is unlocked by the lock/unlock portion via the coupling portion, and a neutral position between the lock position and the unlock position; a position detection portion that detects which of the lock position, the unlock position, and a neutral position the manual operation portion is positioned in; a drive portion that drives the coupling portion to cause the lock/unlock portion to lock and unlock the door; and a control portion that can execute self-lock control in which the driving unit drives the coupling portion to cause the lock/unlock portion to lock the door and self-lock temporary stop control of temporarily stopping the self-lock control when a predetermined time elapses after the position detection portion detects that the lock/unlock portion has changed from the lock position to the unlock position, in which the control portion switches from the self-lock control to the self-lock temporary stop control upon detecting that the manual operation portion is operated from the unlock position to the neutral position and is maintained at the neutral position for a fifth set time or more based on an input from the position detection portion.
A fourth aspect of the present invention provides an electronic lock device including: a body attached to a door including a lock/unlock portion for a switching operation between locking and unlocking; a coupling portion mechanically coupled to the lock/unlock portion; a manual operation portion that is provided in the body, operates integrally with the coupling portion, and is manually operable among a lock position where the door is locked by the lock/unlock portion via the coupling portion, an unlock position where the door is unlocked by the lock/unlock portion via the coupling portion, and a neutral position between the lock position and the unlock position; a position detection portion that detects which of the lock position, the unlock position, and a neutral position the manual operation portion is positioned in; a drive portion that drives the coupling portion to cause the lock/unlock portion to lock and unlock the door; and a control portion that can execute self-lock control in which the driving unit drives the coupling portion to cause the lock/unlock portion to lock the door and self-lock temporary stop control of temporarily stopping the self-lock control when a predetermined time elapses after the position detection portion detects that the lock/unlock portion has changed from the lock position to the unlock position, in which the control portion switches from the self-lock control to the self-lock temporary stop control upon detecting that the manual operation portion is operated from the lock position to the neutral position and is maintained at the neutral position for a sixth set time or more based on an input from the position detection portion.
According to the third aspect of the present invention, the manual operation portion is operated from the unlock position to the neutral position and held for a certain period of time (fifth set time), whereby the self-lock control can be switched to the self-lock temporary stop control. According to the fourth aspect of the present invention, the manual operation portion is operated from the lock position to the neutral position and held for a certain period of time (fifth set time), whereby the self-lock control can be switched to the self-lock temporary stop control.
Switching is performed by the self-lock temporary stop control by simply holding the manual operation portion at the neutral position for a certain period of time from the position (the unlock position in the third aspect, and the lock position in the fourth aspect) at the operation start for switching to the self-lock temporary stop control. Therefore, it is possible to prevent the user from further operating the manual operation portion contrary to the original intention, thereby preventing the switching to the self-lock temporary stop control from being performed. That is, it is possible to reduce the possibility that the user erroneously operates the manual operation portion contrary to the original intention.
In both the third and fourth aspects, the self-lock control can be switched to the self-lock temporary stop control only by operating the manual operation portion once, and therefore the user does not need to memorize the number of times of operation of the manual operation portion. In this respect, in both the third and fourth aspects, it is possible to improve the operability of operation of the manual operation portion required for switching to the self-lock temporary stop control.
A fifth aspect of the present invention provides an electronic lock device including: a body attached to a door including a lock/unlock portion for a switching operation between locking and unlocking; a coupling portion mechanically coupled to the lock/unlock portion; a manual operation portion that is provided in the body, operates integrally with the coupling portion, and is manually operable among a lock position where the door is locked by the lock/unlock portion via the coupling portion, an unlock position where the door is unlocked by the lock/unlock portion via the coupling portion, and a neutral position between the lock position and the unlock position; a position detection portion that detects which of the lock position, the unlock position, and a neutral position the manual operation portion is positioned in; a drive portion that drives the coupling portion to cause the lock/unlock portion to lock and unlock the door; and a control portion that can execute self-lock control in which the driving unit drives the coupling portion to cause the lock/unlock portion to lock the door and self-lock temporary stop control of temporarily stopping the self-lock control when a predetermined time elapses after the position detection portion detects that the lock/unlock portion has changed from the lock position to the unlock position, in which the control portion switches from the self-lock control to the self-lock temporary stop control upon detecting that the manual operation portion is operated from the lock position to the neutral position, is maintained at the neutral position for a sixth set time or more, and is operated to the unlock position within a seventh set time based on an input from the position detection portion.
According to the fifth aspect of the present invention, the manual operation portion is operated from the unlock position to the neutral position and held for a certain period of time (sixth set time), and is operated to the unlock position within the seventh set time, whereby the self-lock control can be switched to the self-lock temporary stop control. This can switch from the self-lock control to the self-lock temporary stop control by a simple operation of stopping the operation once at the time of the unlock operation, and therefore it is possible to improve the operability of operation of the manual operation portion required for switching to the self-lock temporary stop control.
According to the electronic lock device of the present invention, regarding the self-lock temporary stop control, it is possible to reduce the possibility of erroneous operation and improve operability.
Embodiments of the present invention will be described with reference to the accompanying drawings.
With reference to
The latch 2a is operated by door handles 2c and 2d provided on the indoor side and the outdoor side of the door 2, respectively. When the door handles 2c and 2d shown in
The deadbolt 2b is operated by a thumb turn 2e (lock/unlock portion) on the indoor side and a cylinder 2f on the outdoor side. The cylinder 2f is operated by a key not illustrated. The cylinder 2f may be other than a so-called tumbler lock that is operable with a mechanical conventional metal key, and instead of a metal key, for example, a magnetic or electric lock device that is operable by inputting a personal identification number by operating with a portable machine, a smartphone, a card key, or a numeric keypad may be adopted. In place of the thumb turn 2e, a button, a switch, a lever, or the like may be adopted.
When the thumb turn 2c is at the rotation angle position shown in
With reference to
The electronic lock device 1 includes a thumb turn holder 6 (coupling portion) extending from the operation portion 5b of the casing 5 toward the door 2 and mechanically coupled to the thumb turn 2c. In place of the thumb turn holder 6, a holder coupled to a rotation shaft of the thumb turn 2c that becomes accessible by removing the thumb turn 2e from the door 2 may be adopted.
The operation portion 5b of the casing 5 is provided with an operation knob 7 of a rotation type. With reference also to
The operation knob 7 rotates integrally with the thumb turn holder 6 via the gear train 12. With reference to
The rotation of the motor 11 is transmitted to the thumb turn holder 6 via the gear train 12. That is, by rotationally driving the thumb turn holder 6 via the gear train 12, the motor 11 causes the thumb turn 2e to lock and unlock the door 2.
The rotation of the motor 11 is transmitted to the operation knob 7 via the gear train 12. When the motor 11 rotates in an orientation in which the operation knob 7 rotates to the “unlock position”, the thumb turn holder 6, that is, the thumb turn 2e rotates, whereby the deadbolt 2b comes out of the accommodation portion 3b and the door 2 is unlocked. When the motor 11 rotates in an orientation in which the operation knob 7 rotates to the “lock position”, the thumb turn holder 6, that is, the thumb turn rotates, whereby the deadbolt 2b is accommodated in the accommodation portion 3b and the door 2 is locked.
The gear train 12 includes a clutch mechanism (not illustrated). This clutch mechanism transmits the rotation of the motor 11 to the operation knob 7, but does not transmit the manual rotation of the operation knob 7 to the motor 11.
With reference to
The control portion 13 controls the motor 11, the LED light 17, and the buzzer 18 based on inputs from the manual rotation switch 14, the potential sensor 15, and the magnetic sensor 16. The control portion 13 includes a calculation portion 21, an input/output portion 22, a storage portion 23, and a timer 24. The calculation portion 21 performs calculation based on inputs from the manual rotation switch 14, the potential sensor 15, and the magnetic sensor 16 input via the input/output portion 22 with reference to the storage portion 23 and the timer 24, and outputs a command to the motor 11, the LED light 17, and the buzzer 18 via the input/output portion 22. In particular, the control portion 13 outputs, to the motor 11, a command to operate the operation knob 7 in the rotation direction and rotation time such that the operation knob 7 is in the “unlock position” or the “lock position”. The control portion 13 is constructed by hardware such as a CPU, a RAM, and a ROM, and software mounted thereon.
The manual rotation switch 14 detects manual rotation of the operation knob 7. When this detection signal is input, the control portion 13 is activated regarding self-lock temporary stop control described later at the time of manual operation.
The potential sensor 15 detects a rotation angle position of the operation knob 7. The control portion 13 detects the rotation angle position based on an analog voltage signal input from the potential sensor 15, and judges which of the “unlock position”, the “lock position”, and the “neutral position” the operation knob 7 is in. In other words, the potential sensor 15 detects which of the “unlock position”, the “lock position”, and the “neutral position” the operation knob 7 is positioned.
The magnetic sensor 16 detects magnetic force from a magnet installed on the door frame 3 of the door 2. Based on an input from the magnetic sensor 16 that varies depending on the open or close state of the door 2, the control portion 13 judges whether or not the door 2 is in the close state.
The control portion 13 can execute self-lock control. In the self-lock control, the control portion 13 rotates the motor 11 in an orientation in which the operation knob 7 is in the “lock position” in a case where it is detected that the door 2 transitions from the open state to the close state of the door based on an input from the magnetic sensor 16 and the close state of the door 2 has continued for a predetermined time, and the operation knob 7 is in the “unlock position” from the input from the potential sensor 15 (when the door 2 is unlocked), or in a case where although it is detected that the operation knob 7 has been displaced from the “lock position” to the “unlock position” from the input from the potential sensor 15, the input from the magnetic sensor 16 remains in the close state of the door and is not displaced and has continued for a predetermined time. Due to this, the thumb turn 2c rotates via the thumb turn holder 6, the deadbolt 2b protrudes from the door 2 and is accommodated in the accommodation portion 3b, and the door 2 is locked.
The control portion 13 can execute self-lock temporary stop control for temporarily stopping the self-lock control. In the self-lock temporary stop control, even if the close state of the door 2 continues for a predetermined time, the control portion 13 does not execute locking by the motor 11.
Switching from the self-lock control to the self-lock temporary stop control is executed by the user performing a predetermined certain operation on the operation knob 7.
With reference to
It is determined whether or not the operation knob 7 is in the “lock position” in step S1 and the operation knob 7 is operated in step S2 and the manual rotation switch 14 is on (or whether or not to be out of the “lock position”). Then, when the manual rotation switch 14 is on (or detected to have been out of the “lock position”), the timer 24 is started in step S3. When it is detected that the operation knob 7 becomes in the “unlock position” in step S5 before the time measured by the timer 24 reaches the set time Tset_a, the timer is continued as it is. When it is not detected that the operation knob 7 becomes in the “unlock position” before the time measured by the timer 24 reaches the set time Tset_a, the process returns to step S1. Furthermore, when it is not detected that the operation knob 7 becomes in the “lock position” before the time measured by the timer 24 reaches the set time Tset_a in steps S6 and S7, the process returns to step S1. On the other hand, when it is detected that the operation knob 7 has returned to the “lock position” within the set time Tset_a in steps S6 and S7, the self-lock control is switched to the self-lock temporary stop control in step S8. At the time of this switching, the user is notified of the switching by at least one of sound by drive of the buzzer 18 and visual display by drive of the LED light 17. In steps S9 and S10, the timer 24 is cleared once, and then the timer 24 is started again.
Next, in step S11, if the time measured by the timer 24 is less than a set time Tset_b (third set time), the process proceeds to step S12. If it is detected that the operation knob 7 is in the “unlock position” in step S12, that is, if the operation knob 7 is operated from the “lock position” to the “unlock position” by the user, the process proceeds to step S14 to maintain the self-lock temporary stop control, and the timer 24 is cleared in step S15. If it is not detected that the operation knob 7 is in the “unlock position” in step S12, the process returns to step S11.
On the other hand, if the time measured by the timer 24 is equal to or greater than the set time Tset_b (third set time) in step S11, the process proceeds to step S13. In step S13, the motor 11 is operated. The motor 11 rotates the operation knob 11 from the “lock position” to the “unlock position”, and causes the thumb turn 2e to unlock the door 2 via the thumb turn holder 6. Thereafter, the process proceeds to steps S14 and S15.
The control in steps S11 to S15 is as follows in short. First, when the set time Tset_b (third set time) elapses from the switching from the self-lock control to the self-lock temporary stop control, the motor 11 drives the thumb turn holder 6 to cause the thumb turn 2e to unlock the door 2, and continues the self-lock temporary stop control with the operation knob 7 being in the “unlock position”. On the other hand, even if it is detected that the operation knob 7 is operated from the “lock position” to the “unlock position” based on an input from the potential sensor 15 before the set time Tset_b (third set time) is reached since the switching from the self-lock control to the self-lock temporary stop control, the self-lock temporary stop control is continued.
Next, if it is detected that the operation knob 7 is in the “lock position” in step S16, that is, if it is detected that the operation knob 7 is operated from the “unlock position” to the “lock position” by the user, the timer 24 starts in step S17. When it is detected that the operation knob 7 is not in the “lock position”, that is, the operation knob 7 is operated by the user from the “lock position” before the time measured by the timer 24 reaches a set time Tset_c (fourth set time) as in steps S18 and S19, the process returns to step S16. On the other hand, when the time measured by the timer 24 becomes equal to or greater than the set time Tset_c (fourth set time), the self-lock temporary stop control is switched to the self-lock control in step S20. At the time of this switching, the user is notified of the switching by at least one of sound by drive of the buzzer 18 and visual display by drive of the LED light 17. Thereafter, after the timer 24 is cleared in step S19, the process returns to step S1.
The control in steps S16 to S20 is as follows in short. That is, when it is detected that the operation knob 7 is in the “lock position” for equal to or greater than the set time Tset_c (fourth set time) based on an input from the potential sensor 15 during execution of the self-lock temporary stop control, the self-lock temporary stop control is switched to the self-lock control.
From time t0 to before time t1, the operation knob 7 is in the “lock position”, but the operation knob 7 is operated by the user from the “lock position” to the “unlock position” at time t1, and further operated from the “unlock position” to the “lock position” again at time t2. If the time from time t2 (operation to the “unlock position”) to time t2 (operation to the “lock position”) is within the set time Tset_a (first set time), the self-lock control is switched to the self-lock temporary stop control at time t2. At time t3 after the set time Tset_b (third set time) has elapsed from time t2, the motor 11 rotates the operation knob 7 and the thumb turn 2e from the “lock position” to the “unlock position”.
Thereafter, when the user operates the operation knob 7 from the “unlock position” to the “lock position” at time t4, the self-lock temporary stop control is switched to the self-lock control at time t5 when the set time Tsee_c (fourth set time) is reached.
In this example, after the operation knob 7 is operated by the user to switch from the self-lock control to the self-lock temporary stop control at time t2, the user operates the operation knob 7 from the “lock position” to the “unlock position” at time t3 within the set time Tset_b (third set time), but the self-lock temporary stop control is maintained. The rest (time t0 to t2, t4 to t5) of the example of
According to the electronic lock device 1 of the present embodiment, the operation knob 7 is operated from the “lock position” to the “unlock position” within a certain period of time (within the set time Tset_a), and is operated to the “lock position” again, whereby the self-lock control can be switched to the self-lock temporary stop control. Switching to the self-lock temporary stop control is performed only by returning the operation knob 7 to the original “lock position” from the position at the time of operation start for switching to the self-lock temporary stop control, that is, from the “lock position” to the “unlock position” within a certain period of time (within the set time Tset_a). Therefore, it is possible to prevent the user from further operating the operation knob 7 contrary to the original intention, thereby preventing the switching to the self-lock temporary stop control from being performed. That is, it is possible to reduce the possibility that the user erroneously operates the operation knob 7 contrary to the original intention.
Since the self-lock control can be switched to the self-lock temporary stop control only by operating the operation knob 7 twice, the user does not need to memorize the number of times of operation of three or more times of the operation knob 7. In this respect, it is possible to improve the operability of operation of the operation knob 7 required for switching to the self-lock temporary stop control.
Hereinafter, the second to fifth embodiments of the present invention will be described. These embodiments are different only in the control executed by the control portion 13. Therefore, the configuration of the electronic lock device 1 of these embodiments is similar to that of the first embodiment described with reference to
The control related to the self-lock temporary stop control executed by the control portion 13 in the present embodiment shown in
According to the electronic lock device 1 of the present embodiment, it is determined whether or not the operation knob 7 is operated in step S2 and the manual rotation switch 14 is on (or whether or not to be out of the “lock position”). Then, the manual rotation switch 14 is on (or detected to be out of the “lock position”), and the timer 24 is started in step S3. When it is detected that the operation knob 7 is in the “neutral position” in step S5 before the time measured by the timer 24 reaches the set time Tset_a, the timer is continued as it is. When it is not detected that the operation knob 7 becomes in the “neutral position” and further from the “neutral position” to the “lock position” before the time measured by the timer 24 reaches the set time Tset_a, the process returns to step S1. That is, since switching to the self-lock temporary stop control can be performed only by returning the operation knob 7 from the “lock position” to the “neutral position” to the original “lock position” within a certain period of time (within the set time Tset_a), it is possible to reduce the possibility that the user erroneously operates the operation knob 7 contrary to the original intention.
Since it is possible to switch from the self-lock control to the self-lock temporary stop control only by operating the operation knob 7 twice, it is possible to improve the operability of operation of the operation knob 7 required for switching to the self-lock temporary stop control.
With reference to
When it is detected that the operation knob 7 is in the “unlock position” in step S21 and the operation knob 7 is in the “neutral position” in step S22, that is, when the operation knob 7 is operated from the “unlock position” to the “neutral position” by the user, the timer 24 starts in step S23. When it is detected that the operation knob 7 is operated to a position other than the “neutral position” (“unlock position” or “lock position”) before the time measured by the timer 24 reaches the set time Tset_d (the fifth set time) in steps S24 and 25, that is, when the operation knob 7 is operated by the user to a position other than the “neutral position”, the process returns to step S21. On the other hand, when the time measured by the timer 24 becomes equal to or greater than the set time Tset_d (fifth set time) in steps S24 and S25, that is, when it is detected that the operation knob 7 is maintained in the “neutral position” for equal to or greater than the set time Tset_d (fifth set time), the self-lock control is switched to the self-lock temporary stop control in step S26. At the time of this switching, the user is notified of the switching by at least one of sound by drive of the buzzer 18 and visual display by drive of the LED light 17. In step S27, the timer 24 is cleared.
Next, when the position of the operation knob 7 is the “unlock position” in step S28, that is, when it is detected that the operation knob 7 is operated to the “unlock position” by the user, the self-lock temporary stop control is maintained in step S29, and the process returns to step S28. On the other hand, when the position of the operation knob 7 is the “lock position” in step S28, that is, when it is detected that the operation knob 7 is operated to the “lock position” by the user, the self-lock temporary stop control is switched to the self-lock control in step S30, and the process returns to step S21. At the time of switching, the user is notified of the switching by at least one of sound by drive of the buzzer 18 and visual display by drive of the LED light 17.
In place of the control from step S28 to step S30, the control from step S14 to step S18 of the first embodiment (
From time t0 to before time t1, the operation knob 7 is in the “unlock position”, but the operation knob 7 is operated by the user from the “unlock position” to the “neutral position” at time t1. At time t2 when the operation knob 7 reaches the set time Tset_d (fifth set time) after the “neutral position”, the self-lock control is switched to the self-lock temporary stop control. Thereafter, even when the user operates the operation knob 7 from the “neutral position” to the “unlock position” at time t3, the self-lock temporary stop control is performed. When the user operates the operation knob 7 from the “unlock position” to the “lock position” at time t3, the self-lock temporary stop control is switched to the self-lock control.
According to the electronic locking device 1 of the present embodiment, the operation knob 7 is operated from the “unlock position” to the “neutral position” and held for a certain period of time (set time Tset_d), whereby the self-lock control can be switched to the self-lock temporary stop control. Therefore, it is possible to prevent the user from further operating the operation knob 7 contrary to the original intention, thereby preventing the switching to the self-lock temporary stop control from being performed. That is, it is possible to reduce the possibility that the user erroneously operates the manual operation portion contrary to the original intention.
Since the self-lock control can be switched to the self-lock temporary stop control only by operating the operation knob 7 once, the user does not need to memorize the number of times of operation of the operation knob 7. In this respect, it is possible to improve the operability of operation of the operation knob 7 required for switching to the self-lock temporary stop control.
The control related to the self-lock temporary stop control executed by the control portion 13 in the present embodiment shown in
According to the electronic lock device 1 of the present embodiment, since the operation knob 7 is operated from the “lock position” to the “neutral position” and held for a certain period of time (set time Tset_d), whereby the self-lock control can be switched to the self-lock temporary stop control, it is possible to reduce the possibility that the user erroneously operates the operation knob 7 contrary to the original intention.
Since it is possible to switch from the self-lock control to the self-lock temporary stop control only by operating the operation knob 7 once, it is possible to improve the operability of operation of the operation knob 7 required for switching to the self-lock temporary stop control.

When it is detected that the operation knob 7 is in the “lock position” in step S41 and the operation knob 7 is in the “neutral position” in step S42, that is, when the operation knob 7 is operated from the “lock position” to the “neutral position” by the user, the timer 24 starts in step S43, and the LED light 17 is turned on to notify the user of an unstable state (the LED light 17 is turned off when, for example, 1 second elapses, and at that time, the buzzer 18 is driven). Measurement by the timer 24 is continued as it is.
When it is detected that the operation knob 7 is operated to a position other than the “neutral position” (“unlock position” or “lock position”) before the time measured by the timer 24 reaches the set time Tset_e (sixth set time) in steps S44 and 45, that is, when the operation knob 7 is operated by the user to a position other than the “neutral position”, the process returns to step S41. On the other hand, when the time measured by the timer 24 becomes equal to or greater than the set time Tset_e (sixth set time) in steps S44 and S45, that is, when it is detected that the operation knob 7 is maintained in the “neutral position” for equal to or greater than the set time Tset_e (sixth set time), the process proceeds to step S46. In step S46, the timer 24 is cleared once and measurement is stopped. In step S47, in order to prompt the user to operate the operation knob 7 from the “neutral position” to the “unlock position”, the LED light 17 is turned off, and the buzzer 18 is driven for 1 second, for example. Furthermore, in step S48, the timer 24 starts to measurement of time.
Unless the operation knob 7 is operated from the “neutral position” to the “unlock position” within the set time Tset_f (seventh set time) of the time measured by the timer 24 in steps S49 and 50, the process returns to step S41. On the other hand, in steps S49 and 50, when the operation knob 7 is operated from the “neutral position” to the “unlock position” within the set time Tset_f (seventh set time) of the time measured by the timer 24, the process proceeds to steps S51 and 52. In step S52, the self-lock temporary stop control is switched to the self-lock control, and in step S51, turning on of the LED light 17 and driving of the buzzer 18 are executed for a predetermined time (e.g., 0.5 seconds) in order to notify the user that the self-lock temporary stop is started.
The control in steps S51 to 54 is similar to the control in steps S27 to 30 in the third embodiment (
With reference to
When it is detected that the operation knob 7 is in the “lock position” in step S61 and the operation knob 7 is in the “neutral position” in step S62, that is, when the operation knob 7 is operated from the “lock position” to the “neutral position” by the user, the timer 24 starts in step S63, and the LED light 17 is turned on to notify the user of an unstable state (the LED light 17 is turned off when, for example, 1 second elapses, and at that time, the buzzer 18 is driven). Measurement by the timer 24 is continued as it is.
When it is detected that the operation knob 7 is operated to a position other than the “neutral position” (“unlock position” or “lock position”) before the time measured by the timer 24 reaches the set time Tset_e (sixth set time) in steps S64 and 65, that is, when the operation knob 7 is operated by the user to a position other than the “neutral position”, the process returns to step S61. On the other hand, when the time measured by the timer 24 becomes equal to or greater than the set time Tset_c (sixth set time) in steps S64 and S65, that is, when it is detected that the operation knob 7 is maintained in the “neutral position” for equal to or greater than the set time Tset_e (sixth set time), the process proceeds to step S66. In step S66, the timer 24 is cleared and measurement is stopped. In step S67, the LED light 17 is turned off, and the buzzer 18 is driven for 1 second, for example. Furthermore, in step S68, the self-lock control is switched to the self-lock temporary stop control.
Next, when the position of the operation knob 7 is the “unlock position” in step S69, that is, when it is detected that the operation knob 7 is operated to the “unlock position” by the user, the self-lock temporary stop control is maintained in step S70, and the process returns to step S69. On the other hand, when the position of the operation knob 7 is the “lock position” in step S69, that is, when it is detected that the operation knob 7 is operated to the “lock position” by the user, the self-lock temporary stop control is switched to the self-lock control in step S71, and the process returns to step S61. At the time of switching, the user is notified of the switching by at least one of sound by drive of the buzzer 18 and visual display by drive of the LED light 17.
With reference to
The operation position of the operation knob 7 may be detected by either the manual rotation switch 14 or the potential sensor 15, and the start timing of the timer start can be appropriately set. That is, the operation knob 7 in each embodiment may be operated within a predetermined time. The operation knob 7 needs not be of a rotation type, may be of a push type or a lever type, and the casing 5 may be provided with a display portion that displays the operation position of the operation knob 7.
In an embodiment in which the operation knob 7 is operated to the “neutral position”, when the operation knob 7 continues to be held in the neutral position, a warning for calling attention may be issued by at least one of sound by drive of the buzzer 18 and visual display by drive of the LED light 17. Alternatively, the operation knob 7 may be forcibly rotated from the “neutral position” to the “unlock position” or the “lock position” by the motor 11.
