Description

本発明は、非接触式の給電機構を備えた電気錠に関する。   The present invention relates to an electric lock provided with a non-contact power supply mechanism.

従来、ドアの電気錠を構成するのに、錠部をドアの側に設け、この錠部に駆動電流を供給する駆動電源をドア枠の側に設けて、ドア枠とドアとを非接触な状態に維持したまま錠部に電力を供給するものがある。
例えば、従来の電気錠として、以下の特許文献１に示す技術がある。
この電気錠は、ドアとドア枠又は壁などとの間の配線を不要とし、且つ、見栄えが良い電気錠の提供を目的とするもので、次のような構成を有する。
即ち、この電気錠は、ドアに設置された電気錠と、ドア枠又は壁等に設置され電気的な手段により電気錠の施錠や解錠を決定し電気錠を制御するための制御信号を出力する施解錠決定手段を備えている。電気錠の施錠並びに解錠は、電気錠制御部が、施解錠決定手段からの制御信号に基づいて行う。電気錠制御部と施解錠決定手段との間の信号伝送は信号伝送手段が行う。この信号伝送手段は、例えばドアとドア枠とに夫々設けられたコイル間の電磁誘導を利用して行われる。
この結果、ドアとドア枠又は壁などとの間に電源供給や信号伝送のための電気ケーブルを配線する必要がなく、電気ケーブルの断線事故を防止し、施解錠決定手段がドア枠や壁などに設置されているので、ドアに施解錠決定手段が設置されている場合に比べて、ドアの外観を良くし得るとの記載がある。 Conventionally, to configure an electric lock of a door, a lock portion is provided on the door side, and a drive power source for supplying a drive current to the lock portion is provided on the door frame side so that the door frame and the door are not contacted. Some supply power to the lock while maintaining the state.
For example, as a conventional electric lock, there is a technique shown in Patent Document 1 below.
This electric lock is intended to provide an electric lock that does not require wiring between a door and a door frame or a wall and has a good appearance, and has the following configuration.
That is, this electric lock outputs an electric lock installed on the door and a control signal for controlling the electric lock by deciding whether to lock or unlock the electric lock by electric means installed on the door frame or wall. Locking / unlocking determining means is provided. The electric lock control unit performs locking and unlocking of the electric lock based on a control signal from the locking / unlocking determining means. The signal transmission means performs signal transmission between the electric lock control unit and the locking / unlocking determination means. This signal transmission means is performed using, for example, electromagnetic induction between coils provided on a door and a door frame, respectively.
As a result, it is not necessary to wire an electric cable for power supply or signal transmission between the door and the door frame or wall, so that an electric cable disconnection accident is prevented, and the locking / unlocking determining means is used for the door frame or wall. Therefore, there is a description that the appearance of the door can be improved as compared with the case where the locking / unlocking determining means is installed on the door.

特開平１０―２５９３５号公報 （図１、〔０００８〕段落）Japanese Patent Laid-Open No. 10-25935 (FIG. 1, [0008] paragraph)

上記従来の電気錠のごとく電磁誘導方式のものでは、ドア枠の側とドアの側とに互いに正確に位置合わせされた一対の誘導コイルを配置する必要がある。ただし、両者の位置関係が正確でない場合、給電効率が極端に悪くなるという欠点があった。
また、ドアやドア枠は金属で構成される場合も多いが、電磁誘導方式の場合、金属製のドアに磁場が吸収されてしまい、やはり給電効率が低下する。適用可能なドアの種類が制限されてしまうことも汎用性に欠けることとなって好ましくない。
以上のごとく、従来の非接触式の給電機構を備えた電気錠は解決すべき課題が多く存在する。 In the electromagnetic induction type like the above-described conventional electric lock, it is necessary to arrange a pair of induction coils that are accurately aligned with each other on the door frame side and the door side. However, when the positional relationship between the two is not accurate, there is a drawback that the power supply efficiency is extremely deteriorated.
In many cases, the door and the door frame are made of metal. However, in the case of the electromagnetic induction method, the magnetic field is absorbed by the metal door, and the power supply efficiency is lowered. Limiting the types of applicable doors is also not preferable because it lacks versatility.
As described above, there are many problems to be solved in the electric lock provided with the conventional non-contact type power feeding mechanism.

そこで本発明は係る従来の課題を解決し、給電効率に優れ取付けが容易な電気錠を提供することを目的とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the conventional problems and provide an electric lock that is excellent in power supply efficiency and easy to install.

前記ドア枠の側から前記第１活電電極および前記第２活電電極を介して前記ドアの側に至る活電経路と、これとは別に前記ドア枠の側と前記ドアの側とを電気的に接続する受動経路を設けた点にある。 (First feature configuration)
The characteristic configuration of the electric field coupling type electric lock according to the present invention includes a high-frequency voltage generator and a first live electrode to which a high-frequency voltage generated by the high-frequency voltage generator is provided on the door frame side. A second live electrode for detecting an electric field generated from the first live electrode in close proximity to the first live electrode when the door is closed, and power based on the detected electric field. A storage unit for storing the power, and a lock unit driven by the power,
A live path from the door frame side to the door side through the first live electrode and the second live electrode, and separately from the door frame side and the door side This is in the point of providing a passive path for connection.

（作用効果）
本構成のごとく電界結合式の給電機構を用いることで、第１活電電極と第２活電電極との間には必要な対向面積を確保できればよく、従来の電磁誘導方式における送受電コイルどうしの芯合わせのように厳密な位置合わせを強いられるものではない。よって、ある程度の建付け誤差が避けられないドアに対しても電界結合式の給電機構は適切に用いることができる。
また、第１活電電極と第２活電電極とは互いに対向する構造であれば良く、省スペースで且つ取り付けそのものが簡単になる。
さらに、電界は金属を過熱することがないから、金属で構成されるドア枠やドアに対しても電界給電方式の電気錠は適用可能である。
このように、本構成の電気錠であれば、給電効率に優れ、取付けが容易な電気錠を得ることができる。 (Function and effect)
By using the electric field coupling type power supply mechanism as in this configuration, it is only necessary to secure a necessary facing area between the first active electrode and the second active electrode. The exact alignment is not forced like the center alignment. Therefore, the electric field coupling type power feeding mechanism can be appropriately used even for a door in which a certain amount of installation error is unavoidable.
Further, the first live electrode and the second live electrode need only have a structure facing each other, which saves space and facilitates the mounting itself.
Furthermore, since the electric field does not overheat the metal, the electric field feeding type electric lock can be applied to door frames and doors made of metal.
Thus, with the electric lock having this configuration, it is possible to obtain an electric lock that is excellent in power supply efficiency and easy to install.

（第２特徴構成）
本発明に係る電界結合式電気錠は、前記受動経路が、前記ドア枠の側に設けられた第１受動電極と、前記ドアを閉扉した際に前記第１受動電極に近接対向するよう前記ドアの側に設けられた第２受動電極とを備えて構成することができる。 (Second feature configuration)

本構成のごとく、受動経路に第１受動電極と第２受動電極とを備えることで、ドアの開閉状態が判別できるようになる。即ち、ドアが閉じ状態にあるときは、活電経路に通電して活電電極間に電界が形成されると、それに付随して受動電極どうしの間にも電界が形成される。一方、ドアが開き状態にある場合には、活電電極どうしは離間するから電界結合は行われず、受動電極間にも電界は形成されない。よって、受動電極間の電界の形成状況をモニターすることで、ドア開閉状態をドア枠の側で判別することができる。 (Function and effect)
As in this configuration, by providing the passive path with the first passive electrode and the second passive electrode, the open / closed state of the door can be determined. That is, when the door is in a closed state, when an electric field is generated between the active electrodes by energizing the active path, an electric field is also generated between the passive electrodes. On the other hand, when the door is in an open state, the active electrodes are separated from each other, so that electric field coupling is not performed, and no electric field is formed between the passive electrodes. Therefore, by monitoring the formation state of the electric field between the passive electrodes, the door open / closed state can be determined on the door frame side.

（第３特徴構成）
本発明に係る電界結合式電気錠は、前記錠部を格納すると共に前記第２受動電極と電気的に接続された金属ケースを備えて構成することができる。 (Third feature configuration)
The electric field coupling type electric lock according to the present invention may include a metal case that houses the lock portion and is electrically connected to the second passive electrode.

（作用効果）
本構成のごとく、第２受動電極を錠部の金属ケースに電気的に接続することで、金属ケースのうち特にドア枠の側に向く部位などは受動電極の一部として機能させることができる。その結果、受動電極が備える電界検出機能をさらに向上させることができる。 (Function and effect)
As in this configuration, by electrically connecting the second passive electrode to the metal case of the lock portion, a portion of the metal case that is particularly facing the door frame can function as a part of the passive electrode. As a result, the electric field detection function of the passive electrode can be further improved.

（第４特徴構成）
本発明に係る電界結合式電気錠は、前記ドア枠の側に於いて、前記錠部から出退する係止部を受け止める被係止部を備えたプレート部材と、前記第１活電電極とを一体に構成すると共に、当該プレート部材の一部を前記第１受動電極として用い、前記ドアの側に於いて前記錠部および前記第２活電電極を格納する金属ケースを備え、当該金属ケースの一部を前記第２受動電極として用いることができる。 (Fourth feature configuration)
The electric field coupling type electric lock according to the present invention includes a plate member provided with a locked portion that receives the locking portion that moves out and withdraws from the lock portion on the door frame side, the first live electrode, And a metal case for storing the lock portion and the second live electrode on the door side using a part of the plate member as the first passive electrode. Can be used as the second passive electrode.

（作用効果）
このようにドア枠の側に装着する部材とドアの側に装着する部材とを夫々一体化することで、錠としての機能を有する錠部とプレート部材との位置合わせ、および、電力供給機能を有する第１活電電極と第２活電電極との位置合わせ、さらには、電界形成を判別する機能を有する第１受動電極と第２受動電極との位置合わせを同時に行うことができる。よって取付作業効率に優れた電気錠を得ることができる。 (Function and effect)
Thus, by integrating the member to be mounted on the door frame side and the member to be mounted on the door side, the positioning of the lock portion having the function as a lock and the plate member, and the power supply function can be achieved. The first active electrode and the second active electrode can be aligned, and further, the first passive electrode and the second passive electrode having a function of discriminating electric field formation can be simultaneously aligned. Therefore, the electric lock excellent in attachment work efficiency can be obtained.

（第５特徴構成）
本発明に係る電界結合式電気錠は、前記第１活電電極を前記第１受動電極が覆い、前記第２活電電極を前記第２受動電極が覆うように構成することができる。 (Fifth feature configuration)
The electric field coupling type electric lock according to the present invention may be configured such that the first active electrode is covered with the first passive electrode, and the second active electrode is covered with the second passive electrode.

（作用効果）
本構成のごとくドア枠の側及びドアの側の夫々の部位に於いて、活電電極が受動電極に覆われることで、活電電極に外乱が及ぶのを有効に防止することができる。この結果、電界強度が強く維持されて給電効率に優れた電気錠を得ることができる。 (Function and effect)
As in this configuration, the active electrode is covered with the passive electrode at the door frame side and the door side, so that it is possible to effectively prevent the active electrode from being disturbed. As a result, it is possible to obtain an electric lock having a strong electric field strength and excellent power supply efficiency.

（第６特徴構成）
本発明に係る電界結合式電気錠は、前記ドア枠および前記ドアを金属で構成し、前記ドア枠の一部を前記第１受動電極として用いるとともに、前記ドアの一部を前記第２受動電極として用いることができる。 (Sixth feature configuration)

本構成のごとく、受動電極をドア枠の全体あるいはドアの全体で構成することで、受動電極の面積を非常に大きく確保することができる。このため、ドアとドア枠の側に設けた活電電極を広い範囲で覆うこととなり、外部にノイズ源がある場合でもノイズの影響が大幅に低減される。よって、給電特性が非常に安定した電気錠を得ることができる。 (Function and effect)
By configuring the passive electrode with the entire door frame or the entire door as in this configuration, the area of the passive electrode can be secured very large. For this reason, the live electrode provided on the door and door frame side is covered in a wide range, and even when there is a noise source outside, the influence of noise is greatly reduced. Therefore, it is possible to obtain an electric lock with very stable power feeding characteristics.

〔第１の実施形態〕
（概要）
本発明に係る第１の実施形態を図１乃至図３を用いて説明する。
本発明に係る電界結合式電気錠Ｋ（以下、単に「電気錠」と称する）は、ドア１に設けた錠部２に対してドア枠３の側から電力を供給して開閉動作させるものである。電力の供給は、互いに対向配置した一対の電極間に高周波電圧を印加することで発生する電界を利用する。この方式は、従来から存在する、例えば、対向配置させた一対のコイルを用いる電磁誘導方式の電気錠とは給電の仕組みや装置構成が全く異なる。 [First Embodiment]
(Overview)
A first embodiment according to the present invention will be described with reference to FIGS.
The electric field coupling type electric lock K according to the present invention (hereinafter, simply referred to as “electric lock”) opens and closes the lock portion 2 provided on the door 1 by supplying power from the door frame 3 side. is there. Electric power is supplied by using an electric field generated by applying a high-frequency voltage between a pair of electrodes arranged opposite to each other. This method is completely different from a conventional mechanism, for example, an electromagnetic induction type electric lock using a pair of opposed coils.

本実施形態に係る電気錠Ｋの構成を図１に示す。併せて、当該電気錠Ｋの構成を示すブロック図を図２に示す。ドア枠３の側には、高周波電圧発生部４と第１活電電極Ａ１とを有する送電ユニットＵ１を設けてある。高周波電圧発生部４は、通常の家庭用交流電流などを用いてさらに周波数の高い高周波電圧を発生させるものである。第１活電電極Ａ１は、この高周波電圧発生部４で生成した高周波電圧をドア１の側に供給する電極である。   The configuration of the electric lock K according to the present embodiment is shown in FIG. In addition, a block diagram showing the configuration of the electric lock K is shown in FIG. On the side of the door frame 3, a power transmission unit U1 having a high-frequency voltage generation unit 4 and a first live electrode A1 is provided. The high-frequency voltage generator 4 generates a high-frequency voltage having a higher frequency using a normal household alternating current. The first live electrode A1 is an electrode that supplies the high frequency voltage generated by the high frequency voltage generator 4 to the door 1 side.

ドア１の側には、電力によって駆動される錠部２と、前記第１活電電極Ａ１からの電力を錠部２に伝達する第２活電電極Ａ２を有する受電ユニットＵ２が設けられている。受電ユニットＵ２としては、主に、前記第２活電電極Ａ２と、この第２活電電極Ａ２で受け取った交流電圧を直流に変換するＡＣ／ＤＣコンバータ５と、電力を蓄える蓄電ユニット６とを備えている。
尚、錠部２とは、主に施錠・解錠に際して錠部２の側に設けた係止部７を作動させるモータやドアノブ８等の機構部を含むユニット全体をいう。ドア枠３の側には、錠部２の側から突出した係止部７を受け止める被係止部９が設けてあるが、広義においてはドア枠３の側の部材も含めて錠部２という。 On the door 1 side, a power receiving unit U2 having a lock portion 2 driven by electric power and a second live electrode A2 that transmits power from the first live electrode A1 to the lock portion 2 is provided. . The power receiving unit U2 mainly includes the second live electrode A2, an AC / DC converter 5 that converts the alternating voltage received at the second live electrode A2 into direct current, and a power storage unit 6 that stores electric power. I have.
The lock unit 2 refers to the entire unit including a mechanism unit such as a motor and a door knob 8 that actuate a locking unit 7 provided on the lock unit 2 side when locking / unlocking. On the door frame 3 side, a locked portion 9 for receiving the locking portion 7 protruding from the lock portion 2 side is provided, but in a broad sense, including the members on the door frame 3 side, the lock portion 2 is also included. .

(活電電極)
ドア枠３の側の送電ユニットＵ１からドア１側の受電ユニットＵ２に至る給電経路を活電経路１０という。一方、これと並行してドア枠３の側とドア１の側とを電気的に接続する経路を受動経路１１という。
ここで説明する活電電極は、上記活電経路１０の一部を構成する。活電電極には、ドア枠３の側に設けた第１活電電極Ａ１と、ドア１の側に設けた第２活電電極Ａ２とがある。図１に示すごとくこれら活電電極は、所定面積の平板状の部位を有する。第１活電電極Ａ１と第２活電電極Ａ２との間には、活電経路１０に高周波電圧を印加した場合に極性の異なる電界が交互に発生する。この電界の強さに応じてドア１の側に電力が供給される。よって、第１活電電極Ａ１および第２活電電極Ａ２の対向面積は、供給する電力の大きさ等に応じて適宜変更することが可能である。 (Active electrode)
A power feeding path from the power transmission unit U1 on the door frame 3 side to the power receiving unit U2 on the door 1 side is referred to as a live path 10. On the other hand, a path that electrically connects the door frame 3 side and the door 1 side in parallel with this is referred to as a passive path 11.
The live electrode described here constitutes part of the live path 10. The live electrode includes a first live electrode A1 provided on the door frame 3 side and a second live electrode A2 provided on the door 1 side. As shown in FIG. 1, these live electrodes have a plate-shaped portion having a predetermined area. Between the first live electrode A1 and the second live electrode A2, when a high frequency voltage is applied to the live path 10, electric fields having different polarities are alternately generated. Electric power is supplied to the door 1 according to the strength of the electric field. Therefore, the facing area between the first active electrode A1 and the second active electrode A2 can be appropriately changed according to the magnitude of the supplied power and the like.

電界結合方式では、活電電極どうしの対向面がある程度確保できていれば、従来の電磁誘導方式の電磁コイルのごとく双方の位置合わせを厳密に行う必要はない。ただし、双方の活電電極どうしを正確に位置合わせすることは両電極間の給電効率の良否に影響する。よって、双方の電極は極力正確に位置合わせするのが望ましい。
また、一方の活電電極を大きく形成することも可能である。しかし、両活電電極間に形成される電界の強さは小さい方の電極面積で決定されるから、位置合わせが正確になされるならば一方の電極面積を敢えて大きくする必要はない。 In the electric field coupling method, as long as the facing surfaces of the live electrodes are secured to some extent, it is not necessary to strictly align the both as in the conventional electromagnetic induction electromagnetic coil. However, accurate positioning of the two live electrodes affects the quality of power feeding between the two electrodes. Therefore, it is desirable to align both electrodes as accurately as possible.
It is also possible to make one active electrode large. However, since the strength of the electric field formed between the two active electrodes is determined by the smaller electrode area, it is not necessary to darely increase the area of one of the electrodes if alignment is performed accurately.

（受動電極）
第１活電電極Ａ１と第２活電電極Ａ２との間で電界結合を形成するためには、これら活電経路１０と並行して受動経路１１を形成しなければならない。図１には、受動経路１１の一部を構成する受動電極を示してある。ここでは、受動電極として、ドア枠３の側に設ける第１受動電極Ｂ１と、ドア１の側に設ける第２受動電極Ｂ２とを備えた例を示す。図１では、第１受動電極Ｂ１および第２受動電極Ｂ２は、互いに対向近接配置された第１活電電極Ａ１と第２活電電極Ａ２とを対向方向外側から挟むように配置してある。また、第１受動電極Ｂ１と第２受動電極Ｂ２とは、第１活電電極Ａ１あるいは第２活電電極Ａ２とほぼ同じ大きさに形成してある。 (Passive electrode)
In order to form electric field coupling between the first active electrode A1 and the second active electrode A2, the passive path 11 must be formed in parallel with these active paths 10. FIG. 1 shows a passive electrode that constitutes a part of the passive path 11. Here, the example provided with 1st passive electrode B1 provided in the door frame 3 side and 2nd passive electrode B2 provided in the door 1 side as a passive electrode is shown. In FIG. 1, the first passive electrode B <b> 1 and the second passive electrode B <b> 2 are arranged so as to sandwich the first active electrode A <b> 1 and the second active electrode A <b> 2 that face each other and face each other from the outside in the facing direction. Further, the first passive electrode B1 and the second passive electrode B2 are formed to have substantially the same size as the first active electrode A1 or the second active electrode A2.

受動電極は、主には、活電経路１０に高周波電圧を印加した際に、電界結合が確実に発生しているか否かを検知する検知機能を有する。活電電極間に電界が形成されると、それに付随して受動電極間にも電界が形成される。よって、この受動電極間の電圧をモニタすることで、活電電極間で電界が形成されたか否か、即ち、ドア１が閉じ状態にあるか開き状態にあるかをドア枠３の側で判別することができる。   The passive electrode mainly has a detection function of detecting whether or not electric field coupling is reliably generated when a high-frequency voltage is applied to the live path 10. When an electric field is formed between the active electrodes, an electric field is also generated between the passive electrodes. Therefore, by monitoring the voltage between the passive electrodes, it is determined on the side of the door frame 3 whether an electric field is formed between the active electrodes, that is, whether the door 1 is in a closed state or an open state. can do.

尚、受動電極の大きさは、図１のごとく活電電極と必ずしも同じ大きさである必要はない。受動電極の大きさは例えば以下の観点から適宜決定することができる。   The size of the passive electrode is not necessarily the same as that of the live electrode as shown in FIG. The size of the passive electrode can be appropriately determined from the following viewpoints, for example.

一つは、形成される電界の安定性の観点である。受動電極は面積が広いほど第１受動電極Ｂ１と第２受動電極Ｂ２との間に形成される電界は強くなる。よって、ある程度の面積を有することで上記電界発生の検知機能が向上する。また、面積が大きい分、双方の受動電極を離間させても良いから、ドア１の電気錠Ｋを構成する場合にはドア１の建付け誤差の吸収範囲が広くなって好ましい。   One is from the viewpoint of the stability of the electric field formed. The larger the area of the passive electrode, the stronger the electric field formed between the first passive electrode B1 and the second passive electrode B2. Therefore, the electric field generation detection function is improved by having a certain area. In addition, since both passive electrodes may be separated by a large area, when the electric lock K of the door 1 is configured, the range of absorption of the installation error of the door 1 is preferably widened.

もう一つは活電電極のシールド効果の観点である。図１に示すごとく、第１受動電極Ｂ１および第２受動電極Ｂ２は、第１活電電極Ａ１と第２活電電極Ａ２とを挟む状態に配置してある。これにより、双方の活電電極にノイズが載るのを防止している。この点においては、夫々の受動電極は、近接して配置される活電電極よりも大きなものであるとノイズの遮蔽効果が高まって好ましい。   The other is the viewpoint of the shielding effect of the live electrode. As shown in FIG. 1, the first passive electrode B1 and the second passive electrode B2 are arranged so as to sandwich the first active electrode A1 and the second active electrode A2. This prevents noise from being placed on both active electrodes. In this respect, it is preferable that each passive electrode is larger than the active electrodes arranged close to each other because the noise shielding effect is enhanced.

さらに、シールド効果を高めるためには、例えば、図１において、第１受動電極Ｂ１あるいは第２受動電極Ｂ２を格納しているケース１２を金属製とし、夫々の受動電極とケース１２とを電気的に連通させる。これにより、第１活電電極Ａ１あるいは第２活電電極Ａ２は、略直方体をしたケース１２の一方面に露出し、これを取り囲む他の五面はケース１２の金属表面が覆うこととなる。本構成とすることで、夫々の活電電極に周囲からのノイズが載るのを効果的に阻止することができる。この形態では、ケース１２の底面、即ち、ドア枠３に対向する二面のうちドア枠３から遠い側の面が受動電極となり、施錠解錠の状態を判別するセンサとして機能する。また、当該底面を含む五つの面、換言すれば、第２活電電極Ａ２を有するドア枠３の側に向く面を除く五つの面は、第２活電電極Ａ２に対するノイズ遮断機能を発揮することとなる。   Further, in order to enhance the shielding effect, for example, in FIG. 1, the case 12 storing the first passive electrode B1 or the second passive electrode B2 is made of metal, and each passive electrode and the case 12 are electrically connected. Communicate with. Thus, the first live electrode A1 or the second live electrode A2 is exposed on one surface of the substantially rectangular parallelepiped case 12, and the other five surfaces surrounding it are covered with the metal surface of the case 12. By adopting this configuration, it is possible to effectively prevent noise from the surroundings from being placed on each active electrode. In this embodiment, the bottom surface of the case 12, that is, the surface far from the door frame 3 among the two surfaces facing the door frame 3 serves as a passive electrode, and functions as a sensor for determining the state of locking and unlocking. In addition, the five surfaces including the bottom surface, in other words, the five surfaces excluding the surface facing the side of the door frame 3 having the second live electrode A2, exhibit a noise blocking function with respect to the second live electrode A2. It will be.

（蓄電ユニット）
図１に示すごとくドア１の側には蓄電ユニット６を設けてあり、この蓄電ユニット６に対してドア枠３の側から電力を供給して蓄電ユニット６を充電する。例えば、ドア枠３の側に設けた図外の１００Ｖ交流電源からドア１の側に電力を供給し、ＡＣ／ＤＣコンバータ５を介して交流を直流に変換したのち蓄電ユニット６に電力を蓄える。この蓄電は、ドア１が閉じ状態にあるとき、即ち、第１活電電極Ａ１と第２活電電極Ａ２とが対向位置にあるときに行われる。 (Electric storage unit)
As shown in FIG. 1, a power storage unit 6 is provided on the door 1 side, and power is supplied to the power storage unit 6 from the door frame 3 side to charge the power storage unit 6. For example, power is supplied to the door 1 side from an unillustrated 100V AC power source provided on the door frame 3 side, and AC is converted to DC via the AC / DC converter 5 and then stored in the power storage unit 6. This power storage is performed when the door 1 is in a closed state, that is, when the first live electrode A1 and the second live electrode A2 are in the opposing positions.

蓄電ユニット６に蓄えられた電力は、例えばドア１を開く際のモータ駆動に用いられる。解錠操作は、例えば錠部２に設けた操作ボタン１３により行う。解錠動作によって蓄電ユニット６の電力が消費されても、順次、ドア枠３の側から電力が供給されるので、蓄電ユニット６は常に満充電状態を保つことができる。蓄電手段としては、充放電可能な二次電池やコンデンサユニットなどを用いることができる。   The electric power stored in the power storage unit 6 is used for driving a motor when the door 1 is opened, for example. The unlocking operation is performed by, for example, the operation button 13 provided on the lock unit 2. Even when the power of the power storage unit 6 is consumed by the unlocking operation, the power is sequentially supplied from the door frame 3 side, so that the power storage unit 6 can always be fully charged. As the power storage means, a chargeable / dischargeable secondary battery, a capacitor unit, or the like can be used.

（錠部）
本実施形態に係る錠部２は、図１に示すごとく、送電ユニットＵ１および受電ユニットＵ２に隣接して設けてある。当該錠部２のケース１２は金属で構成してある。この錠部２は受電ユニットＵ２の金属製のケース１５に電気的に接続しておく。これにより、ケース１２のうち特にドア枠３の側に向く部位などは受動電極の一部として機能するから、受動電極が備える電界検出機能とシールド機能とがさらに向上する。 (Lock part)
As shown in FIG. 1, the lock portion 2 according to the present embodiment is provided adjacent to the power transmission unit U1 and the power reception unit U2. The case 12 of the lock portion 2 is made of metal. The lock portion 2 is electrically connected to the metal case 15 of the power receiving unit U2. Thereby, since the site | part which faces especially the door frame 3 side etc. of the case 12 functions as a part of passive electrode, the electric field detection function and shielding function with which a passive electrode is provided further improve.

（実施例）
本発明の電気錠Ｋは具体的には以下のように実施することができる。第１・第２活電電極Ａ１，Ａ２および第１・第２受動電極Ｂ１，Ｂ２として、ドアの厚みに収まる幅の金属プレートを用い、これを図１に示すごとく、平面方向が互いに平行となるように四枚のプレートを配置した。
これらのうち、ドア枠３の側の第１受動電極Ｂ１は、ドア枠３に固定されて被係止部９としての孔部を備えたプレート部材１４に電気的に接続した。一方、ドア１の側の第２受動電極Ｂ２は、錠部２の金属ケース１２に電気的に接続した。 (Example)
Specifically, the electric lock K of the present invention can be implemented as follows. As the first and second live electrodes A1 and A2 and the first and second passive electrodes B1 and B2, metal plates having a width that can be accommodated in the thickness of the door are used. As shown in FIG. Four plates were arranged so that
Among these, the 1st passive electrode B1 by the side of the door frame 3 was electrically connected to the plate member 14 which was fixed to the door frame 3 and was provided with the hole as the to-be-latched part 9. FIG. On the other hand, the second passive electrode B <b> 2 on the door 1 side was electrically connected to the metal case 12 of the lock portion 2.

電源として例えば一般家庭用の１００Ｖ交流電源をスイッチング素子を用いた高周波電圧発生部４で変換し、高周波・高電圧を第１活電電極Ａ１と第２活電電極Ａ２との間に発生させて電界結合状態とした。この周波数および電圧を調節することにより、ドアとドア枠との間の隙間（約８ｍｍ）を電力伝送するのに最適な制御を行った。   As a power source, for example, a general household 100V AC power source is converted by the high frequency voltage generator 4 using a switching element, and a high frequency / high voltage is generated between the first active electrode A1 and the second active electrode A2. It was set as the electric field coupling state. By adjusting the frequency and voltage, optimal control was performed for power transmission in the gap (about 8 mm) between the door and the door frame.

高周波電圧発生部４からは、第１活電電極Ａ１に対して常に或いは定期的に高周波の電圧が印加される。よって、ドア１が閉じ状態にある場合には、受動電極の側でも電界が周期的に変化する。逆に、ドア１が開き状態にある場合には、活電電極どうしあるいは受動電極どうしが離間するから、夫々の間の部位に電界は発生しない。よって、電圧の周期的変化の有無を送電ユニットＵ１の側でモニタすることでドア１の開閉状態を判別することができる。   From the high-frequency voltage generator 4, a high-frequency voltage is applied to the first active electrode A1 constantly or periodically. Therefore, when the door 1 is in the closed state, the electric field also periodically changes on the passive electrode side. On the contrary, when the door 1 is in the open state, the active electrodes or the passive electrodes are separated from each other, so that an electric field is not generated at a portion between them. Therefore, the open / closed state of the door 1 can be determined by monitoring the presence or absence of a periodic change in voltage on the power transmission unit U1 side.

〔第１の別実施形態〕
上記実施形態のごとく、受動経路１１に受動電極を備えた電気錠Ｋであれば、通電回路が確実に確保できるから木製のドア１にも適用可能である。しかし、図４、図５に示すごとく、ドア１が金属製の場合には、上記受動電極は必ずしも必要ではない。つまり、ドア枠３およびドア１が金属で構成される場合、ドア１を閉めた状態では、ドア枠３の端面とドア１の端面との間に互いに平行な対向面が形成される。この面を受動電極として利用する。よって、送電ユニットＵ１は第１活電電極Ａ１を備えると共に、上記第１の実施形態における第１受動電極Ｂ１に代えて、当該第１受動電極Ｂ１をに接続していた配線をドア枠３に接地する構成とすると好適である。 [First Alternative Embodiment]
As in the embodiment described above, the electric lock K provided with the passive electrode in the passive path 11 can be applied to the wooden door 1 because the energization circuit can be reliably secured. However, as shown in FIGS. 4 and 5, when the door 1 is made of metal, the passive electrode is not always necessary. That is, when the door frame 3 and the door 1 are made of metal, opposed surfaces that are parallel to each other are formed between the end surface of the door frame 3 and the end surface of the door 1 when the door 1 is closed. This surface is used as a passive electrode. Therefore, the power transmission unit U1 includes the first live electrode A1, and instead of the first passive electrode B1 in the first embodiment, the wiring connecting the first passive electrode B1 to the door frame 3 is provided. It is preferable that the grounding is used.

一方、ドア１の側でも、受電ユニットＵ２は第２活電電極Ａ２を備えると共に、上記第１の実施形態における第２受動電極Ｂ２に代えて、当該第２受動電極Ｂ２に接続していた配線をドア１に接地する構成とすると好適である。これらの等価回路を図５に示す。   On the other hand, on the door 1 side, the power receiving unit U2 includes the second active electrode A2, and the wiring connected to the second passive electrode B2 instead of the second passive electrode B2 in the first embodiment. Is preferably grounded to the door 1. These equivalent circuits are shown in FIG.

このような構成によっても、電界結合式の電気錠Ｋを構成することができる。ただし、本構成の場合、ドア１の開閉状態をドア枠３の側で判別することは困難となる。つまり、受電電極として機能するドア枠３あるいはドア１は、その対向面の面積、あるいは、金属ボリュームが極めて大きい。そのため、活電電極どうしの間に形成された電界に対応して、これらドア枠３とドア１との間に電界が形成されたとしても、電圧変化の測定はドア枠３などの一箇所に於いてされるから、当該位置で測定できる電圧変化は極めて小さいものとなる。   Also with such a configuration, the electric field coupling type electric lock K can be configured. However, in this configuration, it is difficult to determine the open / closed state of the door 1 on the door frame 3 side. That is, the door frame 3 or the door 1 that functions as a power receiving electrode has an extremely large area or metal volume of the facing surface. Therefore, even if an electric field is formed between the door frame 3 and the door 1 corresponding to the electric field formed between the live electrodes, the voltage change is measured at one place such as the door frame 3. Therefore, the voltage change that can be measured at the position is extremely small.

ただし、このことは、外部からノイズが載るような場合には、ノイズの影響が希釈されるから、ドア枠３やドア１は非常に安定した受動電極となる。つまり、活電電極のシールド効果の高い電気錠Ｋを得ることができる。   However, this means that when noise is applied from the outside, the influence of the noise is diluted, so that the door frame 3 and the door 1 become very stable passive electrodes. That is, the electric lock K having a high shielding effect of the live electrode can be obtained.

〔第２の別実施形態〕
送受電ユニットＵ１，Ｕ２および錠部２の金属ケース１２等は、例えば図６に示すように、それらを一体に形成することができる。具体的には、ドア枠３の側に設ける第１活電電極Ａ１及び高周波電圧発生部４は金属ケース１２の中に併せて組み込み、この金属ケース１２に錠の被係止部９も一体形成する。ドア枠３の側の第１受電電極は、錠の被係止部９を構成するプレート状の部位１６をそのまま利用する。 [Second alternative embodiment]
For example, as shown in FIG. 6, the power transmission / reception units U1, U2 and the metal case 12 of the lock unit 2 can be integrally formed. Specifically, the first live electrode A1 and the high-frequency voltage generator 4 provided on the door frame 3 side are incorporated together in a metal case 12, and the locked portion 9 of the lock is integrally formed in the metal case 12. To do. The first power receiving electrode on the door frame 3 side uses the plate-like portion 16 constituting the locked portion 9 of the lock as it is.

一方、ドア１の側に設ける第２活電電極Ａ２及び錠部２、蓄電ユニット６等は共通の金属ケース１２に一体的に組み込む。第２受動電極Ｂ２は、金属ケース１２の側面のうち係止部７が出退する面、即ち、ドア枠３の側に対向する面部をそのまま利用する。   On the other hand, the second live electrode A2, the lock portion 2, the power storage unit 6 and the like provided on the door 1 side are integrally incorporated in a common metal case 12. The second passive electrode B <b> 2 uses the surface of the metal case 12 where the locking portion 7 is withdrawn, i.e., the surface facing the door frame 3 as it is.

このようにドア枠３の側に装着する部材と、ドア１の側に装着する部材とを一体化することで、錠部２の係止部７と被係止部９との位置合わせと、送受電ユニットＵ１，Ｕ２の位置合わせとを同時に行えるため電気錠Ｋの取付効率が向上する。   Thus, by integrating the member to be mounted on the door frame 3 side and the member to be mounted on the door 1 side, the alignment of the locking portion 7 and the locked portion 9 of the lock portion 2 is achieved. Since the positioning of the power transmission / reception units U1, U2 can be performed simultaneously, the mounting efficiency of the electric lock K is improved.

〔第３の別実施形態〕
上記実施形態では、第１受動電極Ｂ１及び第２受動電極Ｂ２を設けることでドア１の開閉状態を判別できる例を示した。それに加え、例えば、以下の構成を備えることで、錠の施解錠状態をも判断することが可能となる。このような構成は集合住宅などに用いると便利な場合がある。 [Third Another Embodiment]
In the said embodiment, the example which can discriminate | determine the opening / closing state of the door 1 by providing 1st passive electrode B1 and 2nd passive electrode B2 was shown. In addition, for example, by providing the following configuration, it is possible to determine the lock / unlock state of the lock. Such a configuration may be convenient when used in an apartment house.

即ち、図２に示すごとく、例えば、ＡＣ／ＤＣコンバータ５と電気錠Ｋとの間に、電気錠Ｋに対して施解錠指令を出力可能な施解錠判別部１７を設けておく。この施解錠判別部１７に対して、ドア枠３の側に設けた施解錠管理端末１８から施錠指令や解錠指令を入力し、これにより、例えば第１活電電極Ａ１に入力する高周波電圧の周波数を変化させる。この周波数の変化を施解錠判別部１７が認識し、電気錠Ｋに施錠指令あるいは解錠指令を送信する。同時に、施解錠判別部１７は、当該判別部の内部に有する例えば図外のオンオフ回路を連続的に動作させる。このオンオフの切り替わりは受動電極間に生じる電界に影響し、施解錠管理端末１８でこれを検知して電気錠Ｋの施解錠状態を認識することができる。   That is, as shown in FIG. 2, for example, a locking / unlocking determination unit 17 capable of outputting a locking / unlocking command to the electric lock K is provided between the AC / DC converter 5 and the electric lock K. For this locking / unlocking determination unit 17, a locking command or an unlocking command is input from a locking / unlocking management terminal 18 provided on the door frame 3 side, whereby, for example, a high-frequency voltage input to the first live electrode A1. Change the frequency. The change in frequency is recognized by the locking / unlocking determining unit 17 and a locking command or unlocking command is transmitted to the electric lock K. At the same time, the locking / unlocking determination unit 17 continuously operates, for example, an on / off circuit (not shown) included in the determination unit. This on / off switching affects the electric field generated between the passive electrodes, and the locking / unlocking management terminal 18 can detect this and recognize the locking / unlocking state of the electric lock K.

本発明に係る電気錠は、建物のドアの他、自動車或いは電車のドア、更には冷蔵庫や自動販売機のドアなど錠部の施錠・解錠を電気的に行うものであれば何れのドアに対しても適用可能である。   The electric lock according to the present invention can be applied to any door as long as it electrically locks and unlocks a lock part such as a door of a car or a train, a door of a refrigerator or a vending machine in addition to a door of a building. It can also be applied to.
