Description

本発明は、電気錠付き操作ユニットに係わり、更に詳しくは開閉体に取付けて引手と施錠機能を付与するための電気錠付き操作ユニットに関するものである。 The present invention relates to an operation unit with an electric lock, and more particularly, to an operation unit with an electric lock attached to an opening / closing body to provide a handle and a locking function.

従来から、キャビネット筐体の前面開口部に開閉可能に設ける扉に、引手と施錠装置が組み込まれた構造のものは各種提供されている。ここで、施錠装置としては、機械式や電気式のものがあるが、電気錠を備えた施錠装置は、電気錠が非通電時にラッチを係合状態のまま維持する、つまり施錠状態となるように構成し、通電時に施錠状態を解除してラッチを回転させ、筐体の框部に対する係合を解除して、扉を開くことができるように構成している。そして、扉を閉じてラッチが筐体の框部に係合した状態で、電気錠に対して非通電とすることで、ラッチの施錠状態に戻すというものである。 2. Description of the Related Art Conventionally, various types of doors provided with a handle and a locking device in a door that can be opened and closed at a front opening of a cabinet housing have been provided. Here, there are mechanical and electric locking devices, but a locking device equipped with an electric lock keeps the latch in the engaged state when the electric lock is de-energized, that is, in the locked state. When the power is turned on, the locked state is released, the latch is rotated, the engagement with the frame of the housing is released, and the door can be opened. When the door is closed and the latch is engaged with the frame of the housing, the electric lock is de-energized to return the latch to the locked state.

電気錠が非通電時に施錠状態となるように構成することは、扉を閉止時に常に施錠状態にすることができ、使用電力を節約できるとともに、施錠忘れを防ぎ、防盗性に優れるといった利点があるが、前記電気錠に商用電源から電力を供給している場合には停電時に、一次電池や二次電池から電力を供給している場合には電池切れ時に、施錠状態から脱却できないといった問題がある。そのため、通常は、機械錠を組み合わせた非常解錠機能を備え、電気錠に電力が供給できなくなった際にも、解錠操作ができるようにしている。 The configuration in which the electric lock is in the locked state when the power is off is advantageous in that the door can be always in the locked state when the door is closed, which saves power consumption, prevents forgetting to lock, and has excellent anti-theft properties. However, there is a problem that the electric lock cannot be released from the locked state when power is supplied from a commercial power supply when the electric lock is supplied from a commercial power supply, or when power is supplied from a primary battery or a secondary battery when the battery runs out. . For this reason, an emergency unlocking function combining a mechanical lock is usually provided so that the unlocking operation can be performed even when power cannot be supplied to the electric lock.

特許文献１には、什器本体の前面開口部を開閉する開閉体に設けた、該開閉体を什器本体に係脱可能に係留する係止機構に連係され、施解錠操作により、前記係止機構の動作を拘束または許容することにより、前記開閉体を施解錠しうる電気式施解錠装置と、非常時に該電気式施解錠装置を解錠しうるようにした機械式施解錠装置とを備える物品収納什器における開閉体の施解錠装置において、前記電気式施解錠装置に、入力された施解錠信号に基づいて前記係止機構の動作を拘束する施錠位置と、同じく係止機構の動作を許容する解錠位置との間を往復移動する施解錠レバーを設けるとともに、前記機械式施錠装置に、その施解錠操作により移動するデッドボルトを設け、解錠操作により前記デッドボルトを解錠方向へ移動させたとき、施錠位置に位置している前記施解錠レバーを解錠位置まで移動させうるように、前記施解錠レバーとデッドボルトとを、連係手段により連係し、かつ施解錠レバーにおけるデッドボルトとの連係部に、施錠操作により前記デッドボルトが施錠方向へ移動したとき、該デッドボルトと連係して、解錠位置にある前記施解錠レバーを施錠位置まで移動させうる連係具を、着脱可能に取付けたことを特徴とする物品収納什器における開閉体の施解錠装置が記載されている。 Patent Literature 1 discloses a locking mechanism provided on an opening / closing body that opens and closes a front opening of a furniture main body, the locking mechanism being removably moored to the furniture main body.

A structure is disclosed, which is rotatably supported by bearings at upper and lower edges of a door, and finally covers a mechanism such as the push button lock device by attaching a back cover to a case body. The unit case, in which members such as a push button lock device, a finger hook, a rotating shaft, an interlocking body, and an operating body are housed in advance, can be detachably attached to a door, thereby simplifying the work of mounting a plurality of parts. In addition, the mounting dimensional error between the components is reduced.

しかし、特許文献２のものは、ケース本体に、押釦錠装置や指掛け体、回動軸、連動体、作動体等の部材を予め収容した状態で、扉の背面に取付け、それから両端部にラッチ爪を装着した作動軸を、ケース本体に形成した挿通部に通して内部機構と連動させるとともに、両端のラッチ爪の軸部を扉の両側縁に設けた軸受部に挿入して取付け、最後にケース本体に裏カバーを装着し、作動軸がユニットケースを貫通した状態とするのであるが、作動軸の組み立て手順に若干の課題がある。 However, in the case of Patent Document 2, a member such as a push button lock device, a finger hook, a rotating shaft, an interlocking body, an operating body, etc. is preliminarily housed in a case body, and attached to the back of the door, and then latched at both ends. The operating shaft equipped with the pawl is passed through the insertion part formed in the case body to interlock with the internal mechanism, and the shaft parts of the latch pawls at both ends are inserted and mounted on the bearing parts provided on both side edges of the door, and finally Although the back cover is attached to the case body so that the operating shaft passes through the unit case, there are some problems in the procedure for assembling the operating shaft.

The connection between the driving piece 68 and the plunger 48 is performed by forming a slit groove 69 in the diametrical direction at the tip of the plunger 48 and inserting a pin 70 across the slit groove 69. This is a structure in which a portion is loosely inserted into the slit groove 69 and an engaging groove 71 opened at the tip of the driving piece 68 is engaged with the pin 70.

前記プランジャー４８は、ソレノイド９の本体７２と先端部に外着したＥリング等の係止リング７３との間に圧縮コイルばね７４を巻装し、該プランジャー４８が突出する方向に弾性付勢している。また、前記連係具４７の基端部と駆動部格納容器５２の内壁との間に圧縮コイルばね７５を介装し、該連係具４７が駆動部格納容器５２から突出する方向へ弾性付勢している。前記連係具４７の先端部には側方へ張り出した部分に前記傾斜面６６を先端側へ向けて傾斜するように形成し、該先端部に前記規制部材３２の連係部４６を連係具４７に回動継手構造にて連結している。この回動継手構造は、図９、図１０及び図１３に示すように、前記連係具４７の先端部に側設した軸部７６の先端に直径方向へ二つのダボ７７，７７を突設し、一方、前記規制部材３２の連係部４６に前記軸部７６とダボ７７，７７の外形に一致した挿入孔７８を形成し、該挿入孔７８に前記軸部７６とダボ７７，７７を挿入し、ダボ７７，７７が挿入孔７８を貫通した状態で前記規制部材３２を９０°回転させて抜け止め状態で使用する。前記連係具４７と規制部材３２は直線状に連結して使用するので、その向きとは９０°異なる向きで挿入できるように形成している。 The plunger 48 is provided with a compression coil spring 74 wound between a main body 72 of the solenoid 9 and a locking ring 73 such as an E-ring externally attached to the distal end of the plunger 48. I'm going. Also, a compression coil spring 75 is interposed between the base end of the linking tool 47 and the inner wall of the drive unit storage container 52, and the linking tool 47 is elastically biased in a direction to protrude from the drive unit storage container 52. ing. At the distal end of the linking tool 47, the inclined surface 66 is formed so as to incline toward the distal end side at a portion protruding laterally, and the linking section 46 of the regulating member 32 is attached to the linking tool 47 at the distal end. They are connected by a rotating joint structure. In this rotary joint structure, as shown in FIGS. 9, 10, and 13, two dowels 77, 77 project in the diametrical direction from the tip of a shaft 76 provided on the tip of the linking tool 47. On the other hand, an insertion hole 78 corresponding to the outer shape of the shaft portion 76 and the dowels 77 is formed in the linking portion 46 of the regulating member 32, and the shaft portion 76 and the dowels 77 are inserted into the insertion hole 78. The restricting member 32 is rotated by 90 ° with the dowels 77 and 77 penetrating the insertion hole 78 to be used in a state where it is prevented from coming off. Since the linking tool 47 and the regulating member 32 are used by being connected linearly, they are formed so that they can be inserted in a direction different from the direction by 90 °.

また、前記機械錠７のデッドボルト６２の先端は、前記連係具４７の傾斜面６６に摺接する先端摺動部６５となっているが、具体的には先端摺動部６５は、前記傾斜面６６と同傾斜の斜面で形成している。尚、前記デッドボルト６２の先端を屈曲して前記先端摺動部６５としても良い。 The tip of the dead bolt 62 of the mechanical lock 7 is a tip sliding portion 65 that slides on an inclined surface 66 of the linking tool 47. Specifically, the tip sliding portion 65 is 66 are formed with the same slope. Note that the tip of the dead bolt 62 may be bent to form the tip sliding portion 65.

先ず、電気錠６を用いて解錠状態にするには、前記扉２の表面側の認証手段１０に暗礁番号を入力し、その制御回路からの指令を受けて前記ソレノイド９に通電すると、前記プランジャー４８は、圧縮コイルばね７４の弾性付勢力に抗して本体７２側に引き込まれ、前記カム部材４９を図９（ａ）の時計回りに回転させ、前記作動片６３が前記連係具４７の係止部６４に当接した状態で、前記圧縮コイルばね７５の弾性付勢力に抗して該連係具４７を駆動部格納容器５２の内部に引き込むようにスライド変位させる。当然、前記連係具４７のスライド変位と同じように前記規制部材３２がスライド変位し、該規制部材３２の規制凸部３６と前記引手３のアーム部３１の凸部３３の位置がずれて当該引手３を手前に引いて回転させることができ、それによって前記ラッチ駆動機構１４の連動部材２８の連動片５３を操作突起５４で押して、シャフト２７を回転させ、前記ラッチ５を回転させて筐体１の框部に対する係合を解除して扉２を開くことができる。 First, in order to use the electric lock 6 to unlock the door, a reef number is input to the authentication means 10 on the front side of the door 2 and the solenoid 9 is energized in response to a command from the control circuit. The plunger 48 is retracted toward the main body 72 against the elastic biasing force of the compression coil spring 74, and rotates the cam member 49 clockwise in FIG. 9A. In the state of contact with the locking portion 64, the linking tool 47 is slid and displaced so as to be drawn into the drive unit storage container 52 against the elastic biasing force of the compression coil spring 75. Naturally, the regulating member 32 is slid and displaced in the same manner as the sliding displacement of the linking tool 47, and the position of the regulating convex portion 36 of the regulating member 32 and the convex portion 33 of the arm portion 31 of the tab 3 is shifted. 3 can be pulled forward and rotated, whereby the interlocking piece 53 of the interlocking member 28 of the latch drive mechanism 14 is pushed by the operation projection 54 to rotate the shaft 27 and rotate the latch 5 to rotate the housing 1 Can be disengaged from the frame portion and the door 2 can be opened.

それから、前記ソレノイド９への通電を遮断すると、前記圧縮コイルばね７４の弾性付勢力によって前記プランジャー４８が突出し、前記圧縮コイルばね７５の弾性付勢力によって前記連係具４７が駆動部格納容器５２から突出して初期状態に復帰し、前記規制部材３２の規制凸部３６と前記引手３のアーム部３１の凸部３３の位置が一致して、前記引手３を引いても扉２の表面板１５と間に規制部材３２を挟み込むので、それ以上の回転は規制され、もって前記ラッチ５は筐体１の框部に対する係合が維持され、施錠装置４が施錠状態となる。 Then, when the energization of the solenoid 9 is cut off, the plunger 48 is projected by the elastic biasing force of the compression coil spring 74, and the linking tool 47 is moved from the driving unit storage container 52 by the elastic biasing force of the compression coil spring 75. When the tab 3 is pulled out and returned to the initial state, the position of the restricting convex portion 36 of the restricting member 32 and the position of the convex portion 33 of the arm portion 31 of the tab 3 coincide with each other. Since the regulating member 32 is interposed therebetween, further rotation is regulated, so that the latch 5 is kept engaged with the frame of the housing 1 and the locking device 4 is locked.

ここで、電池切れ等の何らかの故障で前記ソレノイド９に通電できなくなった場合、つまり非常時に扉２を開く必要が生じると、前記指入れ空間１２からキー６１を鍵穴１１に差し込んで、前記機械錠７を解錠状態に回転させると、前記デッドボルト６２が図９（ｂ）の矢印の方向に突出し、先端摺動部６５が連係具４７の傾斜面６６を押圧し、該傾斜面６６が退避する方向、つまり前記連係具４７が駆動部格納容器５２の内部に引き込まれる方向に力が作用し、前記圧縮コイルばね７５の弾性付勢力に抗して該連係具４７が駆動部格納容器５２の内部に引き込まれ、前記ソレノイド９に通電したときと同じように、前記規制部材３２を解錠状態にスライド変位させることができ、前記引手３を手前に引けるようになり、前記ラッチ５を回転させて筐体１の框部に対する係合を解除して扉２を開くことができる。この際に、前記カム部材４９の作動片６３から連係具４７の係止部６４は離れ、カム部材４９とは無関係に動作する。 Here, if the solenoid 9 cannot be energized due to a failure such as a battery exhaustion, that is, if it is necessary to open the door 2 in an emergency, the key 61 is inserted into the keyhole 11 from the finger insertion space 12 and the mechanical lock is inserted. When the lock 7 is rotated to the unlocked state, the dead bolt 62 protrudes in the direction of the arrow in FIG. 9B, the tip sliding portion 65 presses the inclined surface 66 of the linking tool 47, and the inclined surface 66 is retracted. A force acts in a direction in which the linking tool 47 is drawn into the drive unit storage container 52, and the linking tool 47 moves against the drive unit storage container 52 against the elastic urging force of the compression coil spring 75. The restriction member 32 can be slid and displaced to the unlocked state in the same manner as when the solenoid 9 is energized and the latch 9 can be pulled forward, and the latch 5 rotates. It can open the door 2 by releasing the engagement with rail portion of the housing 1 so. At this time, the locking portion 64 of the linking tool 47 is separated from the operating piece 63 of the cam member 49, and operates independently of the cam member 49.

また、非常解錠状態から、前記キー６１を施錠操作すると、前記デッドボルト６２が反対に後退し、前記連係具４７は圧縮コイルばね７５の弾性付勢力によって駆動部格納容器５２から突出する方向にスライド変位し、また前記規制部材３２も同様にスライド変位して初期状態に復帰し、施錠装置４が施錠状態となるのである。 When the key 61 is locked from the emergency unlocked state, the dead bolt 62 is retracted in the opposite direction, and the linking tool 47 is protruded from the driving unit storage container 52 by the elastic biasing force of the compression coil spring 75. The slide member is slid and the regulating member 32 is similarly slid and returned to the initial state, so that the locking device 4 is in the locked state.

前記駆動部格納容器５２は、図１０に示すように、本体容器７９と蓋８０からなり、本体容器７９に前述のソレノイド９、機械錠７、連係具４７、カム部材４９及び圧縮コイルばね７５等の部品を組み込んで、蓋８０を嵌め殺し的に嵌合する。このように組み立てた駆動部格納容器５２を図１４に示すように、前記操作ユニット８の機構部収容部５０に嵌着して施錠装置４を内蔵させる。 As shown in FIG. 10, the drive unit storage container 52 includes a main body container 79 and a lid 80. The main body container 79 includes the solenoid 9, the mechanical lock 7, the linking tool 47, the cam member 49, the compression coil spring 75, and the like. Then, the lid 80 is fitted to the cover 80 in such a manner that the cover 80 is fitted. As shown in FIG. 14, the drive unit storage container 52 assembled as described above is fitted into the mechanism housing 50 of the operation unit 8 so that the locking device 4 is built therein.

前述のように、前記操作ユニット８の本体ケース部４０の中央部に前記引手枠部４４を設け、該引手枠部４４を挟んで一側に機構部収容部５０を、他側に制御部収容部５１が配置されているが、前記機構部収容部５０にはソレノイド９を収容し、前記制御部収容部５１には認証手段１０と制御回路が収容されるので、前記本体ケース部４０に電気錠６のソレノイド９と認証手段１０間を繋ぐコード（図示せず）を引掛ける機能を設けている。つまり、図１４及び図１５に示すように、前記本体ケース部４０の外側側面にコードフック８１，…を複数設けている。 As described above, the handle frame portion 44 is provided at the center of the main body case portion 40 of the operation unit 8, and the mechanism housing portion 50 is housed on one side of the handle frame portion 44, and the control portion housing is housed on the other side. Although the solenoid unit 9 is housed in the mechanism housing unit 50 and the authentication unit 10 and the control circuit are housed in the control unit housing unit 51, the main body case unit 40 A function is provided for hooking a code (not shown) connecting the solenoid 9 of the lock 6 and the authentication means 10. That is, as shown in FIGS. 14 and 15, a plurality of cord hooks 81 are provided on the outer side surface of the main body case portion 40.
