Description

[Technical Field]

[0001] The present invention relates to a transmitter that transmits a lock signal and an unlock signal by wireless communication to a receiver that is attached to an object such as a door together with the lock body of an electric lock. and A receiving device that receives the transmitted locking signal or unlocking signal and causes the lock body to lock or unlock. Place and The present invention relates to a transmitting / receiving system including the above. [Background technology]

[0002] For example, the following patent document discloses a locking device (locking system) that has a control unit that controls an electric lock based on the analysis of data captured by a camera and non-contact communication (ID authentication) with a portable device (such as an RFID tag) using an RFID transceiver unit.

[0003] In this case, the electric lock (key opening / closing drive unit) houses a locking / unlocking motor and an electric lock control unit in a housing built into the door near the doorknob, and also includes an external operator attached to the wall around the door and an internal operator attached inside the room. The external operator includes an external monitor, camera, external microphone, IR sensor (human presence sensor), external speaker, external push button (external input device), transmitting / receiving antenna (RFID transmitting / receiving unit), external operator control unit, external operator memory, etc. The internal operator includes an internal monitor (touch panel), internal microphone, internal speaker, internal push button (internal input device), internal operator control unit, internal operator memory, etc.

[0004] This locking device is configured so that the electric lock automatically locks the door when it is closed. It also has a configuration that allows unlocking by operating an external push button, by contactless communication with a portable device (ID authentication), by resident face recognition processing based on facial photograph data, or by operating an internal push button. This prevents the electric lock from being unlocked by someone who should be restricted from unlocking, while allowing the electric lock to be smoothly unlocked by someone who should be allowed to unlock it.

[0005] [Patent Document 1] JP 2019-157392 A (pages 4-9, figures 1-7) Summary of the Invention [Problem to be solved by the invention]

[0006] However, the locking device disclosed in the above-mentioned patent document has the following problems to be solved.

[0007] Specifically, in the locking device disclosed in the above patent document, in order to enable an automatically locked electric lock to be unlocked at any timing, the external operating device continuously monitors whether an external push button has been operated and whether a person is near the door, and the internal operating device continuously monitors whether a touch panel or an internal push button has been operated. Therefore, this locking device requires a continuous supply of power to the external operating device and the internal operating device. Therefore, this locking device has a problem in that it is difficult to use in environments where it is difficult to connect to a constant power source such as commercial AC.

[0008] Furthermore, in the locking device disclosed in the above patent document, since the electric lock is built into the door, it is necessary to supply power to the door to operate the locking / unlocking motor, electric lock control unit, etc. In this case, when building an electric lock into a swing-type door, power can be supplied to the door through a flexible power line installed near the hinges or pivot shaft that support the door. However, because the power line is bent and stretched each time the door is opened and closed, there is a risk of the power line being broken, making it difficult to maintain a suitable operational state for a long period of time. Furthermore, when building an electric lock into a sliding-type door, it is necessary to supply power to the electric lock through a long power line that is slackened so as not to interfere with the movement of the door, or to contact electrodes with metal rails installed along the direction of door movement and supply power to the electric lock through the rails and electrodes. This makes the configuration complex, prone to malfunction, and makes it difficult to maintain a suitable operational state for a long period of time.

[0009] The present invention has been made to solve such problems, and is capable of locking / unlocking an electric lock even in an environment where it is difficult to connect to a constant power source, and can maintain a suitable operable state for a long period of time. Send The main purpose is to provide a receiving system. [Means for solving the problem]

[0010] The present invention Transmitting and receiving system teeth, A transmission / reception system including a transmission device and a reception device, It is attached to the target together with the electric lock body and connected to the lock body. The aforementioned a transmitter-side communication unit configured to be able to transmit a locking signal and an unlocking signal to a receiver by wireless communication; an operation unit capable of performing an operation to instruct transmission of the locking signal and the unlocking signal; and a transmitter-side control unit that causes the transmitter-side communication unit to transmit the locking signal and the unlocking signal in response to an operation on the operation unit. and, a power transmission unit of a contactless power supply system configured to be able to transmit power supplied from a power storage unit to the receiving device; and the transmitter side control unit butWhen a predetermined power transmission start condition is satisfied, the power transmitting unit is controlled to transmit power to the receiving device, and when a predetermined transmission start condition is satisfied in which the operation unit is operated to instruct transmission of either the locking signal or the unlocking signal and the receiving device is in a state where it can receive the locking signal or the unlocking signal, the transmitting device side communication unit transmits either the locking signal or the unlocking signal. , the receiving device Locking signal and The aforementioned a receiving device side communication unit configured to be able to receive an unlocking signal; and a receiving device side control unit that controls the lock main body to lock when the locking signal is received by the receiving device side communication unit, and that controls the lock main body to unlock when the unlocking signal is received by the receiving device side communication unit. and, A contactless power supply receiving unit configured to receive power transmitted from an external power supply device and the receiving device side control unit but In a state where the power transmitted from the external power supply device is received by the power receiving unit, when the locking signal is received by the receiving device side communication unit and a predetermined locking permission condition is satisfied, the power received by the power receiving unit is transmitted to the lock main body to lock the lock, and when the unlocking signal is received by the receiving device side communication unit and a predetermined unlocking permission condition is satisfied, the power received by the power receiving unit is transmitted to the lock main body to unlock the lock. 、 The transmitting device is provided with an insertion section that can be inserted into an insertion hole that is provided in the attachment target, and a power transmitting coil in the power transmitting section is disposed in the insertion section, and the receiving device is provided with an insertion section into which the insertion section inserted into the insertion hole can be inserted, and a power receiving coil in the power receiving section is disposed in the insertion section. 、 The transmitting device is provided with an engaging portion that can be engaged with an engaged portion that is provided on either the attachment target or the receiving device, and is configured so that the inserting portion can be maintained in an inserted state in the insertion hole and the inserted portion by engaging the engaging portion with the engaged portion. do.

[0013] Therefore, the present invention Send According to the receiving system, power transmitted from the transmitter to the receiver can be used to transmit power from the receiver to the electric lock, thereby operating the lock itself. This allows the electric lock to be locked / unlocked even in environments where it is difficult to connect to a constant power source such as commercial AC. Furthermore, when the receiver is attached to a door or other installation site, power lines, rails, electrodes, etc., for supplying power to the electric lock from outside the door are not required. This reliably prevents malfunctions due to power line breaks or changes in contact resistance between the rails and electrodes. This allows the system to maintain a suitable operational state for a long period of time. Furthermore, when the transmitter is not located in a position where it can transmit power to the receiver, i.e., when power is not being transmitted from the transmitter to the receiver, power is not transmitted from the receiver to the electric lock, preventing the electric lock from being locked / unlocked by someone not carrying the transmitter.

[0015] Also According to the transmitting and receiving system of the present invention, power can be transmitted from the transmitting device to the receiving device while the receiving device is attached to the attachment object without exposing the receiving device on the surface of the attachment object, such as a door, so that the transmitting and receiving system can be used without spoiling the aesthetic appearance of the attachment object. Also, by disposing a power transmitting coil in an insertion portion that can be inserted into an insertion hole or an insertion portion, and disposing a power receiving coil in the insertion portion so that the power transmitted from the power transmitting coil can be received, power cannot be transmitted from a power transmitting portion that cannot be inserted into the insertion hole or the insertion portion to the power receiving portion of the receiving device, so that the electric lock can be reliably prevented from being locked / unlocked by a person who does not carry a transmitting device with an insertion portion. In addition, after inserting the insertion part into the insertion part, the user can release the insertion part and operate the operation part, etc., so the electric lock can be locked / unlocked reliably and easily without causing operational errors when issuing locking or unlocking commands.

[0016] In addition, in the transmission / reception system of the present invention, the power transmission coil is arranged in the insertion section so that its winding axis is positioned along the insertion direction of the insertion section into the insertion hole and the inserted section, and the power receiving coil is arranged in the inserted section so that its winding axis is positioned along the insertion direction and is located around the power transmission coil when the insertion section is inserted into the inserted section.

[0017] Therefore, according to the transmission / reception system of the present invention, when the insertion portion is fully inserted into the insertion portion, the power transmission coil and the power receiving coil are able to be sufficiently magnetically coupled, thereby more reliably preventing a situation in which power is transmitted from the power transmission portion, which cannot be inserted into the insertion hole or insertion portion, to the power receiving portion of the receiving device, causing the electric lock to be locked / unlocked. [Effects of the Invention]

[0020] The present invention Send The receiving system makes it possible to lock / unlock an electric lock even in environments where it is difficult to connect to a constant power source, allowing the electric lock to be maintained in a suitable operational state for a long period of time and preventing the electric lock from being locked / unlocked by someone who is not carrying a transmitting device.

[0022] Hereinafter, the present invention will be described with reference to the accompanying drawings. Send An embodiment of a receiving system will now be described.

[0023] The transmission / reception system 1 shown in Figure 1 is an example of a "transmission / reception system" and is equipped with a transmitting device 2 and a receiving device 3, and is configured to be able to lock / unlock an electric lock X attached to a door 10 (see Figure 2), which is an example of an "attachment target."

[0024] In this case, the electric lock X is an example of an "electric lock," and as shown in Figure 2, it is equipped with a lock body Xa having a motor (not shown) that slides a deadbolt (not shown) disposed on the door body 10a of the door 10 to insert or remove the deadbolt into or from a receiving seat (not shown) disposed on the frame body 10b, and this lock body Xa is disposed near the handle 10c of the door 10. The door body 10a of the door 10 is also provided with a slit 10s, which is an example of an "insertion hole," and as will be described later, by inserting a transmitter 2 into this slit 10s, it is possible to transmit power Pw and a locking signal Sc and an unlocking signal So from the transmitter 2 to a receiver 3 attached to the door body 10a.

[0025] The transmitting device 2 is an example of a "transmitting device" and an "external power supply device," and is configured to transmit power Pw to the receiving device 3, transmit a locking signal Sc and an unlocking signal So to the receiving device 3 by wireless communication, and receive a notification signal Sr transmitted from the receiving device 3. As shown in FIG. 1 , the transmitting device 2 includes a power storage unit 21, a power supply unit 22, a power transmitting unit 23, a communication unit 24, an operation unit 25, a display unit 26, a control unit 27, and a memory unit 28.

[0026] The power storage unit 21 is an example of a "power storage unit," and the transmission / reception system 1 of this example employs a configuration in which the power storage unit 21, which is built into the transmission device 2 as a component, is used as a power source to operate each component of the transmission device 2 and to transmit power Pw from the transmission device 2 to the reception device 3. The power supply unit 22, in cooperation with the control unit 27, constitutes a "transmission device side control unit," and under the control of the control unit 27, supplies power stored in the power storage unit 21 to each component of the transmission device 2 and transmits the power stored in the power storage unit 21 from the power transmission unit 23 to the reception device 3. The power transmission unit 23 is an example of a "contactless power supply type power transmission unit," and as shown in FIGS. 4 to 7, includes a power transmission coil 23a, which is an example of a "power transmission coil," and is configured to be able to transmit power supplied from the power storage unit 21 to the reception device 3 as power Pw under the control of the power supply unit 22, as shown in FIG. 1.

[0027] The communication unit 24 is an example of a "transmitter-side communication unit" and transmits a lock signal Sc, an unlock signal So, etc. to the receiving device 3, etc., under the control of the control unit 27, and receives a notification signal Sr, etc., transmitted from the receiving device 3, etc. In this case, in this example, as an example, the communication unit 24 is configured as a wireless communication module capable of short-range wireless communication conforming to the Bluetooth (registered trademark) standard, and is configured to be able to transmit and receive various types of data via wireless communication with a communication unit 33 of the receiving device 3, which will be described later.

[0028] The operation unit 25 is an example of an "operation unit" and includes an operation switch that can be operated to instruct transmission of a locking signal Sc or an unlocking signal So to the receiving device 3, and outputs an operation signal corresponding to the switch operation to the control unit 27. Under the control of the control unit 27, the display unit 26 displays the remaining amount of power stored in the power storage unit 21 and displays a message corresponding to the notification signal Sr transmitted from the receiving device 3.

[0029] The control unit 27 comprehensively controls the transmitting device 2. Specifically, as will be described later, when an instruction to lock / unlock is given by operating a switch on the operation unit 25 with the transmitting device 2 inserted into the slit 10s of the door main body 10a (an example of "when a predetermined power transmission start condition is satisfied"), the control unit 27 controls the power supply unit 22 to transmit the power supplied from the power storage unit 21 from the power transmitting unit 23 to the receiving device 3 as power Pw.

[0030] Furthermore, after starting the transmission of electric power Pw, when an alarm signal Sr is transmitted from the receiving device 3 and received by the communication unit 24 to notify that the locking signal Sc and the unlocking signal So are ready to be received (an example of a "state in which the predetermined transmission start condition is satisfied in which the receiving device is ready to receive the locking signal and the unlocking signal"), the control unit 27 causes the communication unit 24 to transmit the locking signal Sc to the receiving device 3 if the above switch operation has instructed to lock, or causes the communication unit 24 to transmit the unlocking signal So to the receiving device 3 if the above switch operation has instructed to unlock.

[0031] Furthermore, as will be described later, when the communication unit 24 receives a notification signal Sr transmitted from the receiving device 3 after the communication unit 24 transmits a locking signal Sc or an unlocking signal So, the control unit 27 causes the display unit 26 to display the state of the electric lock X notified by the notification signal Sr (such as transition to a locked state, transition to an unlocked state, or no locking or unlocking). The memory unit 28 stores an operating program for the control unit 27, authentication data unique to the receiving device 3, etc.

[0032] The receiving device 3 is an example of a "receiving device," and as shown in Fig. 2, is attached to the door body 10a of the door 10 together with the lock body Xa of the electric lock X and connected to the lock body Xa, and is configured to operate using power Pw transmitted from the transmitting device 2 to receive a locking signal Sc or an unlocking signal So to transition the electric lock X to a locked state or an unlocked state, and to transmit a notification signal Sr to the transmitting device 2. As shown in Fig. 1, the receiving device 3 includes a power receiving unit 31, a power supply unit 32, a communication unit 33, a control unit 34, and a memory unit 35.

[0033] The power receiving unit 31 is an example of a "power receiving unit of a contactless power supply system," and as shown in Figures 4 to 7, includes a power receiving coil 31a, which is an example of a "power receiving coil," and is configured to be able to receive power Pw transmitted from the transmitting device 2. The power supply unit 32, in combination with the control unit 34, constitutes a "receiving device side control unit," and under the control of the control unit 34, supplies the power received by the power receiving unit 31 to each component of the receiving device 3 and transmits power to the electric lock X as power Pwc and Pwo.

[0034] The communication unit 33 is an example of a "receiving device side communication unit" and receives the lock signal Sc and the unlock signal So transmitted from the transmitting device 2, and transmits a notification signal Sr to the transmitting device 2 under the control of the control unit 34. Similar to the communication unit 24 in the transmitting device 2 described above, this communication unit 33 is configured as a wireless communication module capable of short-range wireless communication conforming to the Bluetooth (registered trademark) standard, and is configured to be able to transmit and receive various types of data to and from the transmitting device 2 (communication unit 24) via wireless communication.

[0035] The control unit 34 controls the receiving device 3 overall, and as will be described later, causes the lock body Xa of the electric lock X to lock / unlock by transmitting electric power Pwc and electric power Pwo to the lock body Xa. Specifically, the control unit 34 starts operating when electric power Pw is transmitted to the power receiving unit 31 and power is supplied from the power supply unit 32, and causes the communication unit 33 to transmit a notification signal Sr that notifies that the receiving device 3 (communication unit 33) has transitioned to a state in which it can receive a locking signal Sc and an unlocking signal So.

[0036] Furthermore, when the communication unit 33 receives a locking signal Sc, the control unit 34 controls the power supply unit 32 to transmit power Pwc to the electric lock X (lock main body Xa) to lock the electric lock. Furthermore, when the communication unit 33 receives an unlocking signal So, the control unit 34 controls the power supply unit 32 to transmit power Pwo to the electric lock X (lock main body Xa) to unlock the electric lock.

[0037] Furthermore, when the control unit 34 causes the lock body Xa to lock by transmitting power Pwc, it causes the communication unit 33 to transmit an alarm signal Sr to the transmitting device 2 notifying that the electric lock X has transitioned to a locked state, and when the control unit 34 causes the lock body Xa to unlock by transmitting power Pwo, it causes the communication unit 33 to transmit an alarm signal Sr to the transmitting device 2 notifying that the electric lock X has transitioned to an unlocked state. The memory unit 35 stores the operating program of the control unit 34, authentication data individually assigned to the receiving device 3, etc.

[0038] 2, the transmitter 2 in the transmission / reception system 1 of this example is configured to include a device main body 2a in which the components 21, 22, 24 to 28 are housed within a housing, and an insertion section 2b in which a power transmission section 23 (power transmission coil 23a) connected to the device main body 2a (power supply section 22) via a cable 2c is housed. In this case, the insertion section 2b is an example of an "insertion section," and the power transmission section 23 (power transmission coil 23a) is disposed in a thin plate-like section that can be inserted into a slit 10s provided in the door main body 10a of the door 10, as shown in FIGS.

[0039] Furthermore, in the receiving device 3 in the transmitting / receiving system 1 of this example, as shown in Fig. 2, the components 31-35 are housed in a housing attached to the portion of the door body 10a where the slit 10s is formed, and the power supply unit 32 is connected to the lock body Xa by a cable 3b for transmitting the above-mentioned power Pwc and Pwo to the lock body Xa. As shown in Figs. 3-7, the receiving device 3 is provided with an insertion portion 3a into which the insertion portion 2b inserted into the slit 10s of the door body 10a can be inserted, and a power receiving portion 31 (power receiving coil 31a) is disposed in the insertion portion 3a. Therefore, since the receiving device 3 is used in a state where it is attached to the back side of the portion of the door body 10a where the slit 10s is formed, deterioration of the exterior due to exposure to sunlight or the adhesion of rainwater is preferably avoided.

[0040] In this case, in the transmitter 2 of this example, the power transmission coil 23a is disposed in the insertion portion 2b so that the winding axis is positioned along the insertion direction (the direction of arrow A in FIGS. 3, 4, and 6) of the insertion portion 2b into the slit 10s of the door main body 10a and the inserted portion 3a of the receiver 3. In FIGS. 3, 4, and 6, the position of the winding axis of the power transmission coil 23a is indicated by the dashed dotted line La.

[0041] In the receiving device 3 of this example, the power receiving coil 31a is disposed in the inserted portion 3a so that its winding axis is aligned with the insertion direction of the insertion portion 2b relative to the inserted portion 3a. In FIGS. 3, 4, and 6, the position of the rotation axis of the power receiving coil 31a is indicated by a two-dot chain line Lb. Specifically, in the receiving device 3 of this example, as shown in FIGS. 5 and 7, when the insertion portion 2b of the transmitter 2 is inserted into the inserted portion 3a, the power receiving coil 31a is positioned around the power transmitting coil 23a, and, for example, the power receiving coil 31a is disposed in the inserted portion 3a so that its winding axis coincides with the winding axis of the power transmitting coil 23a. In FIGS. 5 and 7, the positions of the winding axes of the power receiving coil 31a and the power transmitting coil 23a are indicated by a rough dashed line Lc.

[0042] Furthermore, in the transmitting / receiving system 1 of this example, as shown in Figures 3 to 5, as an example, a hook 41, which is an example of an "engaging portion", is provided in the insertion portion 2b of the transmitting device 2, and an engaging pin 42, which is an example of an "engaged portion", is arranged in the inserted portion 3a of the receiving device 3 (an example in which the "engaged portion provided on either the attachment target or the receiving device" is composed of the "engaged portion provided on the receiving device").

[0043] Next, a method of using the transmission / reception system 1 will be described with reference to the accompanying drawings.

[0044] The transmission / reception system 1 of this example is configured so that multiple transmission devices 2 and multiple reception devices 3 can be used in any combination. Specifically, as an example, the reception devices 3 attached to multiple doors 10 can be operated by one transmission device 2 to lock / unlock the doors, or one reception device 3 can be operated by any of the multiple transmission devices 2 to lock / unlock the doors. In the following, to facilitate understanding of the operation of the transmission / reception system 1 (transmission devices 2 and reception devices 3), an example in which one reception device 3 is operated by one transmission device 2 will be described. Furthermore, it is assumed that the attachment of the reception device 3 to the door main body 10a and the connection of the reception device 3 to the electric lock X (lock main body Xa) have already been completed, and therefore a description of these operations will be omitted.

[0045] In this transmitting and receiving system 1, when the insertion portion 2b of the transmitting device 2 is not inserted into the slit 10s of the door main body 10a, that is, when power Pw is not transmitted from the transmitting device 2 to the receiving device 3, the receiving device 3 is in a stopped state. Therefore, in this state, when power is not transmitted from the receiving device 3 to the lock main body Xa, a situation in which the electric lock X is shifted from a locked state to an unlocked state or from an unlocked state to a locked state is preferably avoided.

[0046] On the other hand, for example, when transitioning the electric lock X from an unlocked state to a locked state, the insertion portion 2b of the transmitter 2 is inserted into the slit 10s of the door body 10a. Specifically, while holding the device body 2a of the transmitter 2 with one hand, the insertion portion 2b held with the other hand is inserted into the slit 10s of the door body 10a in the direction of arrow A shown in FIGS. 3, 4, and 6. At this time, the tip of the insertion portion 2b is inserted fully into the deep side of the insertion receiving portion 3a. Next, by moving the insertion portion 2b along the longitudinal direction of the slit 10s in the direction of arrow B, the engagement groove 41a of the hook 41 of the insertion portion 2b engages with the engagement pin 42 of the insertion receiving portion 3a, as shown in FIG. 5. As a result, the insertion portion 2b remains inserted into the slit 10s and the insertion receiving portion 3a even when the hand holding the insertion portion 2b is released.

[0047] In this case, in the transmission / reception system 1 of this example, as described above, the power transmission coil 23a is disposed in the insertion portion 2b so that its winding axis is aligned with the insertion direction of the insertion portion 2b into the slit 10s and the inserted portion 3a. The power receiving coil 31a is disposed in the inserted portion 3a so that its winding axis is aligned with the insertion direction (for example, coincides with the winding axis of the power transmission coil 23a) and is positioned around the power transmission coil 23a when the insertion portion 2b is inserted into the inserted portion 3a. Therefore, in the transmission / reception system 1 of this example, as shown in FIGS. 5 and 7, inserting the insertion portion 2b into the inserted portion 3a results in a favorable magnetic field coupling between the power transmission coil 23a and the power receiving coil 31a when transmitting power Pw, enabling power transmission and reception with sufficiently low magnetic flux linkage. This prepares the electric lock X to transition to the locked state.

[0048] Next, the operator operates the operation unit 25 of the device main body 2a to instruct the locking. At this time, when an operation signal instructing the locking is input from the operation unit 25, the control unit 27 in the transmitting device 2 determines that the "power transmission start condition" is satisfied, and controls the power supply unit 22 to transmit the power stored in the power storage unit 21 from the power transmitting unit 23 to the receiving device 3 as power Pw. In response to this, the power transmitted from the transmitting device 2 is received by the power receiving unit 31 in the receiving device 3, and power from the power supply unit 32 is supplied to each component, causing the control unit 34 to start operating, and also causing the communication unit 33 to transmit a notification signal Sr to the transmitting device 2 to notify that the receiving device 3 is now in a state where it is possible to receive the locking signal Sc and the unlocking signal So.

[0049] Meanwhile, in the transmitting device 2, as soon as the power transmitting unit 23 starts transmitting the power Pw as described above, the control unit 27 monitors whether the notification signal Sr transmitted from the receiving device 3 has been received by the communication unit 24. Furthermore, when the notification signal Sr is transmitted from the receiving device 3 as described above, the control unit 27 determines that the "transmission start condition" has been satisfied, and causes the communication unit 24 to transmit the authentication data stored in the storage unit 28 to the receiving device 3. In this case, the authentication data is unique ID data individually assigned to each transmitting device 2, and the authentication data of the ID assigned to the transmitting device 2 that should be allowed to lock / unlock the electric lock X is registered in advance in the storage unit 35 of the receiving device 3.

[0050] Furthermore, in the receiving device 3, when the communication unit 33 receives authentication data transmitted from the transmitting device 2, the control unit 34 determines whether the ID of the received authentication data matches the ID of the authentication data stored in the memory unit 35. At this time, if the two IDs do not match, the control unit 34 transmits a notification signal Sr from the communication unit 33 to the transmitting device 2, notifying that locking / unlocking of the electric lock X is not permitted. In response to this, the control unit 27 in the transmitting device 2 displays a message or the like on the display unit 26, based on the notification signal Sr received by the communication unit 24, indicating that the electric lock X cannot be locked / unlocked. This allows the user to recognize that the electric lock X cannot be locked.

[0051] On the other hand, when the ID of the authentication data received by the communication unit 33 matches the ID of the authentication data stored in the memory unit 35, the control unit 34 transmits a notification signal Sr, which notifies that locking / unlocking of the electric lock X is permitted, from the communication unit 33 to the transmitting device 2. In response to this, the control unit 27 in the transmitting device 2 determines, based on the notification signal Sr received by the communication unit 24, that locking / unlocking of the electric lock X is permitted, and causes the communication unit 24 to transmit a locking signal Sc to the receiving device 3 in response to an operation on the operation unit 25 (in this example, an operation to instruct locking).

[0052] In the receiving device 3, when the communication unit 33 receives the locking signal Sc transmitted from the transmitting device 2, the control unit 34 determines that the "predetermined locking permission condition" has been met and controls the power supply unit 32 to transmit a portion of the power Pw received by the power receiving unit 31 as power Pwc to the electric lock X (lock main body Xa), thereby locking the electric lock. At this time, the motor supplied with the power Pwc slides the deadbolt and inserts it into the receiving seat, thereby transitioning the electric lock X from the unlocked state to the locked state. After transmitting the power Pwc from the power supply unit 32 to the lock main body Xa as described above, the control unit 34 also controls the communication unit 33 to transmit a notification signal Sr to the transmitting device 2, notifying the electric lock X that the electric lock X has transitioned from the unlocked state to the locked state.

[0053] In response to this, the control unit 27 of the transmitter 2 displays a message or the like on the display unit 26 indicating that the electric lock X has transitioned to the locked state, based on the notification signal Sr received by the communication unit 24. This allows the user to recognize that the locking of the electric lock X has been completed. Next, the user holds the insertion portion 2b and pulls it out of the slit 10s. This separates the power transmission coil 23a of the power transmission unit 23 and the power receiving coil 31a of the power receiving unit 31, stopping the transmission of power Pw from the transmitter 2 to the receiver 3 and causing the receiver 3 to transition to a stopped state. This creates a state in which it is possible to prevent the electric lock X, which has transitioned to the locked state, from unintentionally transitioning to the unlocked state. This completes the series of operations for transitioning the electric lock X from the unlocked state to the locked state.

[0054] Furthermore, when transitioning the electric lock X from a locked state to an unlocked state, the insertion portion 2b of the transmitter 2 is inserted into the slit 10s of the door body 10a, and the operation unit 25 is operated to instruct locking. When transitioning from a locked state to an unlocked state, the control unit 27 of the transmitter 2 transmits and receives an unlock signal So from the communication unit 24 to the receiver 3, and in response, the control unit 34 of the receiver 3 determines that the "predetermined unlocking permission condition" has been satisfied and transmits power Pwo from the power supply unit 32 to the lock body Xa, but the same processing is performed as when transitioning from an unlocked state to a locked state, except that. Therefore, a detailed description of the operation when transitioning to an unlocked state will be omitted.

[0055] In this way, the transmitting device 2 is provided with a contactless power supply type power transmitting unit 23 configured to be able to transmit power supplied from the power storage unit 21 to the receiving device 3, and the control unit 27 controls the power transmitting unit 23 to transmit power Pw to the receiving device 3 when a predetermined power transmission start condition is satisfied, and also controls the communication unit 24 to transmit one of the signals, a locking signal Sc or an unlocking signal So, when an operation on the operation unit 25 instructs the transmitting unit to transmit either the locking signal Sc or the unlocking signal So and the predetermined transmission start condition is satisfied in which the receiving device 3 is in a state where it can receive the locking signal Sc or the unlocking signal So.

[0056] In addition, this receiving device 3 is configured to be attached to the door body 10a of the door 10 together with the lock body Xa of the electric lock X so as to be connectable to the lock body Xa, and is equipped with a contactless power supply type receiving unit 31 configured to be able to receive power Pw transmitted from the transmitting device 2, and when the power receiving unit 31 is receiving the power Pw transmitted from the transmitting device 2, the control unit 34 transmits the power Pw received by the power receiving unit 31 to the lock body Xa as power Pwc to lock the lock when the communication unit 33 receives a locking signal Sc and predetermined locking allowance conditions are satisfied, and when the communication unit 33 receives an unlocking signal So and predetermined unlocking allowance conditions are satisfied, the control unit 34 transmits the power Pw received by the power receiving unit 31 to the lock body Xa as power Pwo to unlock the lock.

[0057] This transmission / reception system 1 is also configured to include the above-mentioned transmission device 2 and reception device 3.

[0058] Therefore, with the transmitter 2, receiver 3, and transmission / reception system 1, power Pw transmitted from the transmitter 2 to the receiver 3 can be used to transmit power Pwc and Pwo from the receiver 3 to the electric lock X to operate the lock main body Xa, making it possible to lock / unlock the electric lock X even in an environment where it is difficult to connect to a constant power source such as commercial AC. Furthermore, when the receiver 3 is attached to a door 10 or the like as an "attachment target," power lines, rails, electrodes, etc. for supplying power to the electric lock X from outside the door 10 are not required, so malfunctions due to breaks in the power lines or changes in contact resistance between the rails and electrodes can be reliably avoided. This makes it possible to maintain a favorable operational state for a long period of time. Furthermore, when the transmitting device 2 is not positioned in a position where it can transmit power Pw to the receiving device 3, i.e., when power Pw is not transmitted from the transmitting device 2 to the receiving device 3, power Pwc and Pwo are not transmitted from the receiving device 3 to the electric lock X, thereby preventing the electric lock X from being locked / unlocked by a person who is not carrying the transmitting device 2.

[0059] In addition, in this transmission / reception system 1, an insertion section 2b that can be inserted into a slit 10s provided in the door body 10a of the door 10 is provided in the transmitting device 2, and a power transmission coil 23a in the power transmission section 23 is arranged in the insertion section 2b, and an insertion section 3a into which the insertion section 2b inserted into the slit 10s can be inserted is provided in the receiving device 3, and a power receiving coil 31a in the power receiving section 31 is arranged in the insertion section 3a.

[0060] Therefore, according to this transmitting / receiving system 1, power Pw can be transmitted from the transmitting device 2 to the receiving device 3 with the receiving device 3 attached to the door body 10a without exposing the receiving device 3 on the surface side of the door body 10a, so the transmitting / receiving system 1 can be used without spoiling the aesthetic appearance of the door 10. Furthermore, by arranging the power transmitting coil 23a in the insertion portion 2b that can be inserted into the slit 10s and the insertion portion 3a, and by arranging the power receiving coil 31a in the insertion portion 3a so as to be able to receive the power Pw transmitted from the power transmitting coil 23a, power Pw cannot be transmitted to the power receiving portion 31 of the receiving device 3 from a "power transmitting portion" that cannot be inserted into the slit 10s or the insertion portion 3a, so it is possible to reliably prevent the electric lock X from being locked / unlocked by a person who does not carry the transmitting device 2 with the insertion portion 2b.

[0061] In addition, in this transmission / reception system 1, the power transmission coil 23a is arranged in the insertion portion 2b so that its winding axis is positioned along the insertion direction of the insertion portion 2b into the slit 10s and the inserted portion 3a, and the power receiving coil 31a is arranged in the inserted portion 3a of the receiving device 3 so that its winding axis is positioned along the above-mentioned insertion direction and is located around the power transmission coil 23a when the insertion portion 2b is inserted into the inserted portion 3a.

[0062] Therefore, according to this transmission / reception system 1, when the insertion portion 2b is fully inserted into the insertion portion 3a, the power transmission coil 23a and the power receiving coil 31a are in a state where they can be sufficiently magnetically coupled, so that it is possible to more reliably prevent a situation in which power Pw is transmitted from the ``power transmission portion'' that cannot be inserted into the slit 10s or the insertion portion 3a to the power receiving portion 31 of the receiving device 3, causing the electric lock X to be locked / unlocked.

[0063] In addition, in this transmission / reception system 1, a hook 41 is provided on the transmission device 2 that can engage with an engagement pin 42 provided on either the door body 10a of the door 10 or the receiving device 3 (in this example, the receiving device 3), and the engagement groove portion 41a of the hook 41 is engaged with the engagement pin 42, thereby enabling the insertion portion 2b to be maintained inserted into the slit 10s and the inserted portion 3a.

[0064] Therefore, according to this transmission / reception system 1, after inserting the insertion portion 2b into the insertion portion 3a, the operator can release his / her hand from the insertion portion 2b and operate the operation portion 25, etc., so that the electric lock X can be reliably and easily locked / unlocked without causing operational errors when instructing to lock or unlock the electric lock X.

[0065] The configurations of the "transmitting device," "receiving device," and "transmitting / receiving system" are not limited to the above-described exemplary configurations of the transmitting device 2, receiving device 3, and transmitting / receiving system 1. Specifically, the transmitting device 2 has a built-in power storage unit 21 as a "power storage unit," and the power supplied from this power storage unit 21 is transmitted from the transmitting device 2 to the receiving device 3. However, instead of (or in addition to) the power storage unit 21, a configuration can also be adopted in which a portable power source (an external power supply device that can be carried together with the transmitting device 2) that includes a primary battery or a secondary battery is connected to the "transmitting device" as a "power storage unit" to transmit power to a "receiving device" such as the receiving device 3.

[0066] Furthermore, although the transmitter 2 has been described as having a thin-plate-shaped insertion portion 2b that can be inserted into the slit 10s serving as an "insertion hole," the shape of the "insertion hole" formed in the "attachment target" is not limited to a slit shape (long hole shape) and can be any opening shape. In this case, if a "round hole" serving as the "insertion hole" is provided in the "attachment target," forming the "insertion portion" in a "round rod shape" and the "inserted portion" in a "round hole shape" allows power to be suitably transmitted from the "power transmitting coil" disposed in the "insertion portion" to the "power receiving coil" disposed in the "inserted portion."

[0067] In addition, an example has been described in which the configuration in which the power transmission coil 23a and the inserted portion 3a are arranged so that the winding axis of the power transmission coil 23a coincides with the winding axis of the power receiving coil 31a when the insertion portion 2b is inserted into the inserted portion 3a. However, instead of this configuration, a configuration can be adopted in which the winding axis of the power transmission coil 23a and the winding axis of the power receiving coil 31a are both positioned along the insertion direction of the insertion portion 2b into the slit 10s and the inserted portion 3a, and the winding axis of the power transmission coil 23a and the winding axis of the power receiving coil 31a are arranged so that they do not coincide with each other (their winding axes are parallel) within a range that satisfies the condition that the power receiving coil 31a is positioned around the power transmission coil 23a when the insertion portion 2b is inserted into the inserted portion 3a.

[0068] Furthermore, although the configuration has been described as an example in which the engaging pin 42 provided in the inserted portion 3a serves as the "engaged portion" and the hook 41 of the transmitter 2 (insertion portion 2b) engages with this, such a configuration can be omitted. Also, instead of (or in addition to) such a configuration, an "engaged portion" can be provided on the "mounting object" such as the door 10, and an "engaging portion" that can engage with this "engaged portion" can be provided on the "insertion portion" of the "transmitter."

[0069] Furthermore, the configuration has been described as an example in which the control unit 27 determines that the "power transmission start condition" has been satisfied when an instruction to transmit a locking signal Sc or an unlocking signal So is given by operating the operation unit 25. However, instead of such a configuration, it is possible to employ a configuration in which an "operation button for instructing the start of power transmission" is provided on the "transmitting device", and the "transmitting device side control unit" determines that the "power transmission start condition" has been satisfied when this "operation button" is operated, or a configuration in which a contactless IC tag is provided on the "attachment target" or the "receiving device", and the "transmitting device side control unit" determines that the "power transmission start condition" has been satisfied when the contactless IC tag previously associated with the "receiving device" to which power should be transmitted is read by the "transmitting device".

[0070] In addition, the example described above uses a receiving device 3 configured to transition the electric lock X to a locked state by transmitting power Pwc to the lock body Xa, and transition the electric lock X to an unlocked state by transmitting power Pwo to the lock body Xa. However, if the "electric lock" is equipped with a controller that controls the operation of the motor in response to a control signal, as an example, a configuration can be adopted in which, while power is being transmitted from the "transmitting device" to the "receiving device," power is continuously transmitted from the "receiving device" to the "lock body," and when the receiving device 3 transmits power Pwc, the "receiving device" transmits a "locking signal" to the "electric lock" to lock it, and when the receiving device 3 transmits power Pwo, the "receiving device" transmits an "unlocking signal" to the "electric lock" to unlock it.

[0071] Furthermore, although an example has been described in which the receiving device 3 is attached to the door body 10a of the door 10 together with the electric lock X, the "attachment target" is not limited to a "door", and various items such as a "window" or a "lid" can be used as the "attachment target" to lock / unlock the "electric lock".
