Description

本発明は、扉枠に設けられたストライクの係止穴に対し、例えばデッドボルトやカマ錠等の係止部材を進退動させることで錠前を電気的に施解錠する電気錠に関するものである。   The present invention relates to an electric lock that electrically locks and unlocks a lock by moving a locking member such as a dead bolt or a hook lock forward and backward with respect to a locking hole of a strike provided in a door frame.

例えばホテルやオフィスビル等の商業施設や公共施設の入出口、集合住宅や一般住宅のエントランスや玄関等には電気錠システムが広く普及している。この電気錠システムでは、各所の電気錠毎に予め割り当てられた特定の暗号や施解錠情報等の各種データが記憶されたカード状記憶媒体を鍵カードとして用い、この鍵カードに記憶された各種データ(例えば特定の暗号による施解錠データ)を読み取り、読み取った各種データを予め登録された情報と照合して正当性を判別し、正常に認証した場合のみ、現在の扉の開閉状態や錠前の施解錠状態に応じて錠前を電気的に施解錠制御している。   For example, electric lock systems are widely used at entrances and exits of commercial facilities and public facilities such as hotels and office buildings, entrances and entrances of housing complexes and ordinary houses. In this electric lock system, a card-like storage medium storing various data such as specific encryption and locking / unlocking information allocated in advance for each electric lock is used as a key card, and various data stored in this key card. (For example, locking / unlocking data with a specific encryption) is read, the read data is collated with pre-registered information to determine the legitimacy, and only when it is successfully authenticated, the current door open / close state and unlocking The lock is electrically locked and unlocked according to the lock state.

そして、この種の電気錠システムに採用される電気錠としては、下記特許文献1を含め、様々なものが提案されている。その一例について説明すると、例えばモータ等の駆動源の駆動力により施錠方向と解錠方向にそれぞれ回動する歯車伝達機構と、この歯車伝達機構の伝達力により作動するとともに、人為的な操作力によっても回動するデッドカムと、デッドカムの作動腕を介して進退動するデッドボルトとを錠箱に備えて電気錠が構成される。この電気錠では、施錠又は解錠操作時に、現在の扉の開閉状態や錠前の施解錠状態に応じて駆動源を駆動し、この駆動源の駆動力によって歯車伝達機構を施錠方向又は解錠方向に回動し、この歯車伝達機構の伝達力によりデッドカムの作動腕を介してデッドボルトを扉枠に設けられたストライクの係止穴に対して進退動させ、デッドボルトを係止穴に係止または係止穴から解除することにより錠前を施解錠している。   Various types of electric locks, including the following Patent Document 1, have been proposed as electric locks employed in this type of electric lock system. An example will be described. For example, a gear transmission mechanism that rotates in a locking direction and an unlocking direction by a driving force of a driving source such as a motor, and the like, and is operated by a transmission force of the gear transmission mechanism. The electric lock is configured by providing the lock box with a dead cam that rotates and a dead bolt that moves forward and backward through the operating arm of the dead cam. In this electric lock, at the time of locking or unlocking operation, the driving source is driven according to the current open / close state of the door or the unlocking state of the lock, and the gear transmission mechanism is locked or unlocked by the driving force of this driving source. The dead bolt is moved forward and backward with respect to the strike hole of the strike provided in the door frame via the dead cam operating arm by the transmission force of the gear transmission mechanism, and the dead bolt is locked to the lock hole. Alternatively, the lock is unlocked by releasing it from the locking hole.

ところで、この種の従来の電気錠では、デッドボルトが突出しきった施錠位置を検出する施錠センサと、デッドボルトが引き込みきった解錠位置を検出する解錠センサとをマイクロスイッチなどの検出器で構成し、これら施錠センサや解錠センサによって現在の施解錠状態を検出していた。
特開2005−232893号公報
By the way, in this type of conventional electric lock, a locking sensor that detects the locking position where the dead bolt has fully protruded and an unlocking sensor that detects the unlocking position where the dead bolt has been fully drawn are detected by a detector such as a microswitch. The present locking / unlocking sensor detects the current locking / unlocking state.
JP-A-2005-232893

しかしながら、上述したマイクロスイッチなどの検出器を用いた従来の電気錠において、施錠センサと解錠センサが両方ともOFFしている位置では、デッドボルトがどの位置に有るのか不明だった。すなわち、ストライクの係止穴に対してデッドボルトが施錠寸前に位置しているのか、解錠寸前に位置しているのか、さらには解錠と施錠の中間に位置しているのか不明であり、デッドボルトの位置(突出状況)を正確に検出することができなかった。   However, in a conventional electric lock using a detector such as the above-described microswitch, it is unclear at which position the dead bolt is located at a position where both the locking sensor and the unlocking sensor are OFF. In other words, it is unclear whether the dead bolt is positioned just before locking, the position just before unlocking, or even between unlocking and locking, with respect to the strike hole of the strike, The position of the dead bolt (protrusion situation) could not be detected accurately.

そこで、本発明は上記問題点に鑑みてなされたものであり、扉枠に設けられたストライクの係止穴に対する係止部材(デッドボルトやカマ錠)の位置(突出状況)を正確に検出することができる電気錠を提供することを目的とするものである。   Therefore, the present invention has been made in view of the above problems, and accurately detects the position (protrusion state) of the locking member (dead bolt or hook lock) with respect to the locking hole of the strike provided in the door frame. It is an object to provide an electric lock that can be used.

And at the time of locking energization or unlocking energization, the deadbolt operation status (protrusion status) is always recognized, and the forward and backward movement of the deadbolt is controlled according to the current locking / unlocking status. Alternatively, it can move to the unlocking position and perform a reliable unlocking operation.

以下、本発明の最良の形態について、添付した図面を参照しながらそれぞれ説明する。図1は本発明に係る電気錠の要部を示すブロック図、図2(a),(b)は本発明に係る電気錠の施錠状態と解錠状態の概略構成図である。   The best mode of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram showing a main part of an electric lock according to the present invention, and FIGS. 2A and 2B are schematic configuration diagrams showing a locked state and an unlocked state of the electric lock according to the present invention.

図1に示すように、本例の電気錠1は、施解錠機構2、施解錠位置検出手段3、制御手段4、駆動手段5を図2に示す錠箱6内に備えて概略構成される。この電気錠1では、施解錠時に、現在の扉の開閉状態や施解錠状態に応じた制御手段4からの指令(施錠指令又は解錠指令)に基づく駆動手段5の駆動により、扉枠のストライク7に設けられた係止穴7aに対して施解錠機構2の係止部材であるデッドボルト2aを直線変位により進退動させ、係止穴7aに対してデッドボルト2aを突出(施錠時)又は引き込む(解錠時)ことにより錠前を電気的に施解錠している。   As shown in FIG. 1, the electric lock 1 of this example is schematically configured by including a locking / unlocking mechanism 2, a locking / unlocking position detecting means 3, a control means 4, and a driving means 5 in a lock box 6 shown in FIG. . In this electric lock 1, when the door is unlocked, the driving means 5 is driven based on a command (locking command or unlocking command) from the control means 4 according to the current door opening / closing state or locking / unlocking state. The dead bolt 2a, which is a locking member of the locking / unlocking mechanism 2, is moved forward and backward by linear displacement with respect to the locking hole 7a provided in 7, and the dead bolt 2a protrudes (when locked) into the locking hole 7a. The lock is electrically unlocked by pulling in (when unlocked).

施解錠機構2は、ストライク7の係止穴7aに対する直線変位の進退動により係止穴7aに係止又は係止穴7aから解除する係止部材としてのデッドボルト2aを含み、駆動手段5からの駆動力をデッドボルト2aに伝達する歯車伝達機構、デッドカムなどの従来より周知の動力伝達機構2bを備えている。   The locking / unlocking mechanism 2 includes a dead bolt 2a as a locking member that is locked to or released from the locking hole 7a by advancing and retreating of the linear displacement with respect to the locking hole 7a of the strike 7. Is provided with a conventionally known power transmission mechanism 2b such as a gear transmission mechanism for transmitting the driving force to the dead bolt 2a, and a dead cam.

図1に示すように、施解錠位置検出手段3は、センサ部11と駆動部12とを有している。センサ部11は、錠箱6内の所定位置に固定された巻回部からなるコイル11aと、コイル11aの巻回部内に一部が臨んでデッドボルト2aと連動するコア11bとを有している。コア11bは、棒状の金属体からなり、一端がデッドボルト2aの基端側に連結され、他端の一部がコイル11aの巻回部の穴の略中心に挿入して設けられる。そして、センサ部11は、コア11bの他端側がコイル11aの巻回部の穴の略中心線上をデッドボルト2aと連動して平行移動するようになっている。   As shown in FIG. 1, the locking / unlocking position detection unit 3 includes a sensor unit 11 and a drive unit 12. The sensor unit 11 includes a coil 11a composed of a winding portion fixed at a predetermined position in the lock box 6, and a core 11b partially facing the winding portion of the coil 11a and interlocking with the dead bolt 2a. Yes. The core 11b is made of a rod-shaped metal body, one end is connected to the base end side of the dead bolt 2a, and a part of the other end is provided by being inserted substantially at the center of the hole of the winding portion of the coil 11a. The sensor unit 11 is configured such that the other end side of the core 11b moves in parallel with the dead bolt 2a on the substantially center line of the hole of the winding part of the coil 11a.

駆動部12は、コイル11aに対するコア11bの変位に応じた変位量信号を出力するための回路として、所定の発振信号を出力する発振回路12a、発振回路12aからの発振信号によってコイル11aに駆動信号を供給するコイル駆動回路12b、コイル11aのインピーダンス変化を検出する検波回路12c、検波回路12cの検出信号を処理してコイル11aに対するコア11bの変位に応じた変位量信号を得る信号処理回路12d、信号処理回路12dの処理によって得られる変位量信号を出力する出力回路12dを備えている。   The drive unit 12 is a circuit for outputting a displacement amount signal corresponding to the displacement of the core 11b with respect to the coil 11a, an oscillation circuit 12a for outputting a predetermined oscillation signal, and a drive signal to the coil 11a by an oscillation signal from the oscillation circuit 12a. A coil drive circuit 12b for supplying a signal, a detection circuit 12c for detecting an impedance change of the coil 11a, a signal processing circuit 12d for processing a detection signal of the detection circuit 12c and obtaining a displacement amount signal corresponding to the displacement of the core 11b relative to the coil 11a, An output circuit 12d that outputs a displacement amount signal obtained by the processing of the signal processing circuit 12d is provided.

ここで、センサ部11のコイル11aのインピーダンスは、コイル11aの巻回部中心の穴にコア11bがどれだけ挿入されているかによって変化する。そして、このインピーダンス変化を駆動部12で検出・信号処理することにより、コア11bの変位に応じた変位量信号として出力している。   Here, the impedance of the coil 11a of the sensor unit 11 varies depending on how much the core 11b is inserted into the hole at the center of the winding portion of the coil 11a. The impedance change is detected and signal-processed by the drive unit 12 to output a displacement amount signal corresponding to the displacement of the core 11b.

このように、施解錠位置検出手段3では、施解錠時にデッドボルト2aと連動するコイル11aの巻回部の穴内でのコア11bの移動に伴うコイル11aのインピーダンスの変化からデッドボルト2aの変位量を検出している。その際、デッドボルト2aに連動して動くコア11bが、コイル11aの巻回部内の穴にどれだけ挿入されているかによって駆動部12の出力信号(変位量信号)が変化し、この出力信号の値(変化量)によってデッドボルト2aの位置が正確に判る。   Thus, in the locking / unlocking position detecting means 3, the displacement amount of the dead bolt 2a from the change of the impedance of the coil 11a accompanying the movement of the core 11b in the hole of the winding part of the coil 11a interlocked with the dead bolt 2a at the time of locking / unlocking. Is detected. At that time, the output signal (displacement amount signal) of the drive unit 12 changes depending on how much the core 11b moving in conjunction with the dead bolt 2a is inserted into the hole in the winding portion of the coil 11a. The position of the dead bolt 2a can be accurately determined by the value (change amount).

これにより、施錠/解錠でない中間位置にデッドボルト2aが有ってもデッドボルト2aの位置が正確に検出することができる。   Thereby, even if the dead bolt 2a exists in the intermediate position which is not locked / unlocked, the position of the dead bolt 2a can be detected accurately.

制御手段4は、施解錠位置検出手段3からの変位量信号と、係止穴7aに対するデッドボルト2aの位置に応じて設定された施錠基準値や解錠基準値とを比較し、これら基準値に対する変位量信号の差から現在のデッドボルト2aの位置(突出状況)を判別している。尚、使用状況によって扉と扉枠との間の距離が変化することがあるため、この距離に応じて前記基準値が最適な値に適宜設定されるようになっている。また、制御手段4は、外部から施錠指示又は解錠指示の入力があったときに、施解錠位置検出手段3からの変位量信号に基づく現在の錠前の施解錠状態や周知の扉開閉検出センサの検出信号(開扉や閉扉の扉状態モニタ信号)に基づく現在の扉扉の開閉状態に応じて駆動手段5がデッドボルト2aを進退動するべく駆動手段5に施錠指令又は解錠指令を出力している。   The control means 4 compares the displacement amount signal from the unlocking position detecting means 3 with the locking reference value and the unlocking reference value set according to the position of the dead bolt 2a with respect to the locking hole 7a, and these reference values The current position of the dead bolt 2a (protrusion situation) is determined from the difference in displacement amount signal with respect to. In addition, since the distance between the door and the door frame may change depending on the use situation, the reference value is appropriately set to an optimum value according to this distance. Further, the control means 4 is configured to detect a current lock / unlock state based on a displacement amount signal from the lock position detection means 3 and a known door opening / closing detection sensor when a lock instruction or an unlock instruction is input from the outside. The drive means 5 outputs a lock command or an unlock command to the drive means 5 to move the dead bolt 2a forward and backward according to the current open / close state of the door based on the detection signal (open / closed door state monitor signal) is doing.

駆動手段5は、制御手段4からの施錠指令又は解錠指令によって駆動されるモータやアクチュエータなどで構成される。駆動手段5は、制御手段4から施錠指令が入力されたときに、デッドボルト2aをストライク7の係止穴7aに突出して係止するように施解錠機構2(動力伝達機構2b)を駆動し、制御手段4から解錠指令が入力されたときは、デッドボルト2aをストライク7の係止穴7aから引き込むように施解錠機構2(動力伝達機構2b)を駆動している。   The drive means 5 is constituted by a motor, an actuator, or the like that is driven by a lock command or an unlock command from the control means 4. The driving means 5 drives the locking / unlocking mechanism 2 (power transmission mechanism 2b) so that the dead bolt 2a protrudes and locks into the locking hole 7a of the strike 7 when a locking command is input from the control means 4. When the unlocking command is input from the control means 4, the locking / unlocking mechanism 2 (power transmission mechanism 2 b) is driven so that the dead bolt 2 a is pulled from the locking hole 7 a of the strike 7.

次に、上記構成による電気錠1の動作について説明する。まず、制御手段4に対して外部から施解錠動作の指示が入力されると(ST1)、現在の施解錠状態を施解錠位置検出手段3からの変位量信号に基づいて判別する(ST2)。その後、現在の扉の開閉状態と合せて動作内容を施錠動作にするか解錠動作にするか決める(ST3)。   Next, operation | movement of the electric lock 1 by the said structure is demonstrated. First, when an instruction for locking / unlocking operation is input from the outside to the control means 4 (ST1), the current locking / unlocking state is determined based on the displacement amount signal from the locking / unlocking position detecting means 3 (ST2). Thereafter, it is determined whether the operation content is to be locked or unlocked in accordance with the current open / closed state of the door (ST3).

そして、動作内容が決まると、制御手段4から駆動手段5に施錠指令又は解錠指令を出力して駆動手段5の駆動により施錠通電又は解錠通電を開始する(ST4)。この施錠通電又は解錠通電により、デッドボルト2がストライク7の係止穴7aに対して所定の変位量だけ進退動する。その際、制御手段4は、施解錠位置検出手段3からの変位量信号を常時取り込み、施錠通電時又は解錠通電時におけるデッドボルト2aの動作状況(突出状況)を認識する(ST5)。そして、制御手段4は、施解錠位置検出手段3からの変位量信号に合せた施解錠通電を行うべく駆動手段5を制御する(ST6)。その後、制御手段4は、通電完了か否かを判別し(ST7)、通電完了するまで施解錠通電を行うべく駆動手段5を制御する。   When the operation content is determined, the control unit 4 outputs a locking command or unlocking command to the driving unit 5 and starts driving energization or unlocking by driving the driving unit 5 (ST4). By this energization of locking or unlocking, the dead bolt 2 moves forward and backward by a predetermined displacement with respect to the locking hole 7a of the strike 7. At that time, the control means 4 always takes the displacement amount signal from the locking / unlocking position detection means 3 and recognizes the operating condition (protruding condition) of the dead bolt 2a at the time of locking energization or unlocking energization (ST5). And the control means 4 controls the drive means 5 to perform the locking / unlocking energization in accordance with the displacement amount signal from the locking / unlocking position detecting means 3 (ST6). Thereafter, the control unit 4 determines whether or not energization is completed (ST7), and controls the drive unit 5 to perform the locking and unlocking energization until the energization is completed.

このように、本例の電気錠1によれば、施解錠制御時に、扉枠に設けられたストライク7の係止穴7aに対するデッドボルト2aの位置(突出状況)を正確に検出することができる。そして、施錠通電時又は解錠通電時には、デッドボルト2aの動作状況(突出状況)を常時認識し、その動作状況に合せてデッドボルト2aの進退動を制御するので、デッドボルト2aを正常な施錠位置又は解錠位置まで移動して確実な施解錠動作を行うことができる。   Thus, according to the electric lock 1 of this example, the position (protrusion state) of the dead bolt 2a with respect to the locking hole 7a of the strike 7 provided in the door frame can be accurately detected during the locking / unlocking control. . And at the time of locking energization or unlocking energization, the operating condition (protruding condition) of the dead bolt 2a is always recognized, and the forward / backward movement of the dead bolt 2a is controlled according to the operating condition, so that the dead bolt 2a is normally locked. It can move to a position or an unlocking position to perform a reliable unlocking operation.

ところで、上述した実施形態では、錠前を施解錠するための係止部材として、ストライク7の係止穴7aに対して直線変位により進退動するデッドボルト2aを例にとって説明したが、ストライク7の係止穴7aに対して回動変位により進退動するカマ錠を係止部材としても良い。そして、カマ錠を係止部材2aとした場合でも、上述したデッドボルトの場合と同様の検出原理でカマ錠の回動変位量を検出することができる。   In the embodiment described above, the dead bolt 2a that moves forward and backward by linear displacement with respect to the locking hole 7a of the strike 7 is described as an example of the locking member for locking and unlocking the lock. A hook lock that moves forward and backward by rotational displacement with respect to the stop hole 7a may be used as the locking member. Even when the hook lock is used as the locking member 2a, the rotational displacement amount of the hook lock can be detected by the same detection principle as that of the dead bolt described above.
