Description

本発明はドアのロック装置に係り、特にスライド型のドアロック装置に関する。   The present invention relates to a door locking device, and more particularly to a sliding door locking device.

例えばトイレのドア等のロック装置として、トイレの内側においてスライド型のロック部材を壁側にスライドしてドアをロックする手段と、ドアの外側においてロック状態の有無を表示する表示する手段とを設けた、ドアのロック装置がある。   For example, as a locking device for a toilet door or the like, a means for locking the door by sliding a slide-type locking member toward the wall inside the toilet and a means for displaying the presence or absence of the locked state outside the door are provided. There is also a door locking device.

このようなスライド型のロック装置でかつロック手段と表示手段とを有するロック装置に関する発明を開示するものとして以下の文献がある。
特開２００７−１８２７３２ 特開２００５−１２０７６７ The following documents disclose such a slide-type locking device and an invention relating to a locking device having a locking unit and a display unit.
JP2007-182732 JP 2005-120767 A

上記各特許文献の発明は、ドアのロックが確実に行なえ、かつロックの有無が表示部において外部に表示される構成となっている。両特許文献記載の発明の表示部は何れも表示部内の表示板を回転させ、表示部の特定の位置に形成された窓を介してその回転位置に対応して表示板の所定部分、即ちロック（施錠）状態或いはアンロック（解錠）状態を示すよう構成されている。   The invention of each of the above patent documents is configured such that the door can be securely locked and the presence or absence of the lock is displayed on the display unit. Both display units of the inventions described in both patent documents rotate a display plate in the display unit, and through a window formed at a specific position of the display unit, a predetermined portion of the display plate, that is, a lock. It is configured to indicate a (locked) state or an unlocked (unlocked) state.

ノブ式のロック装置であればノブ自体或いはノブの中心に位置したつまみを回転させてロックの開閉を行なうため、表示板の回転はノブ或いはつまみと同軸の構造とするだけで実現可能である。これに対してスライド式の構成では直線運動を回転運動に変換する手段が必要となる。上記各実施例では上記表示板の回転作動を実現するため表示板には回転軸が取り付けられ、回転軸先端にはピニオンが設けられ、かつスライド型のロック部材側にはラックが設けられ、このロック部材のスライド方向に対応してピニオンを介して表示板が回転し、表示部の窓に施錠・解錠を表示するよう構成している。   In the case of a knob type locking device, the knob itself or the knob located at the center of the knob is rotated to open and close the lock, so that the rotation of the display board can be realized only by a structure coaxial with the knob or knob. On the other hand, the slide type configuration requires means for converting linear motion into rotational motion. In each of the above embodiments, a rotation shaft is attached to the display plate to realize the rotation operation of the display plate, a pinion is provided at the tip of the rotation shaft, and a rack is provided on the slide type lock member side. The display board rotates via a pinion corresponding to the sliding direction of the lock member, and lock / unlock is displayed on the window of the display unit.

上記のラックとピニオンの構成は回転機構の設置、ラックの取り付け等必然的に部品点数が多くなりこの結果ロック装置全体の構成が複雑となる。またラックとピニオンによるギヤ機構は噛み合わせ部に埃や汚れが入ると作動が不確かとなったり、故障の原因となり、トイレのドア等必ずしも良好でない使用環境下ではやや脆弱な機構であるといえる。   The configuration of the above rack and pinion inevitably increases the number of parts such as the installation of a rotating mechanism and the mounting of the rack, and as a result, the configuration of the entire locking device becomes complicated. The gear mechanism using the rack and pinion can be said to be a somewhat fragile mechanism in an unusable environment such as a toilet door, because operation and operation may be uncertain if dust or dirt enters the meshing portion.

また、スライド型のロック装置及びこれ以外のロック装置も含めて従来のロック装置では、ドア外部からロック状態を解除する手段は設けられていないのが実情である。今後益々高齢化する社会においてはトイレ内等での転倒事故、脳卒中の発症等の緊急事態の発生が懸念されるが、このような事態を想定して今後は何れの形式のロック装置でも緊急時に外部からロック状態を解除できる手段を設けておくことが望ましい。   Moreover, in the conventional lock device including the slide type lock device and other lock devices, there is actually no means for releasing the lock state from the outside of the door. In an increasingly aging society, there are concerns about the occurrence of emergency situations such as falling accidents in the toilets, the occurrence of strokes, etc., but in the future, any type of locking device will be used in an emergency in the future. It is desirable to provide means for releasing the locked state from the outside.

本発明は上記目的に鑑みてなされたものである。
即ち、本発明はドア内部に設置された装置本体部と、ドア外部に設置されかつドアを介して装置本体と接続する表示部とからなり、装置本体はドア内側に固定される支持部と、この支持部に対して摺動するロック部材とを有し、かつ表示部はドアの表面において装置本体の支持部と対向する位置でドアに固定される固定部と、この固定部内を昇降する昇降板と、ロック部材の摺動方向に対応した方向に回動する昇降板駆動部材と、これら各部材を覆うカバー部材とから成ることを特徴とするドアのロック装置である。 The present invention has been made in view of the above objects.
That is, the present invention comprises a device main body installed inside the door, and a display unit installed outside the door and connected to the device main body via the door, the device main body being fixed to the inside of the door; A lock member that slides relative to the support portion, and the display portion is fixed to the door at a position facing the support portion of the main body of the apparatus on the surface of the door; A door locking device comprising a plate, a lifting plate driving member that rotates in a direction corresponding to a sliding direction of the locking member, and a cover member that covers these members.

より具体的にはロック部材は、ロック解除方向に移動するようバネ等の弾性体により付勢され、かつロック時にこの付勢に対向してロック部材をロック位置に係合固定する手段が設けられ、緊急事態等により外部から解錠する必要がある場合にはピン、針金等を用いて外部からこの係合状態を解除することが可能に構成されている。   More specifically, the lock member is biased by an elastic body such as a spring so as to move in the unlocking direction, and means for engaging and fixing the lock member at the lock position is provided opposite to the biasing when locked. When it is necessary to unlock from the outside due to an emergency situation or the like, this engagement state can be released from the outside using a pin, a wire or the like.

ロック部材の所定位置に設けられた係合部と昇降板駆動部材を回動する軸に設けられた係合部材とが係合することにより昇降板駆動部材が回動し、この回動状態に対応して昇降板が昇降することにより表示部の窓に施錠・解錠の状態を表示する構造となっているため、ラックとピニオン等の複雑な歯車機構を必要とせず、構造が簡素であり、装置を安価に提供できると共に、故障の発生が少ない信頼性の高い装置とすることができる。   When the engaging portion provided at a predetermined position of the lock member and the engaging member provided on the shaft for rotating the lifting plate driving member are engaged, the lifting plate driving member is rotated. Correspondingly, the lifting / lowering plate moves up and down to display the locked / unlocked state on the window of the display unit, so there is no need for complicated gear mechanisms such as racks and pinions, and the structure is simple. Thus, the apparatus can be provided at a low cost and can be a highly reliable apparatus with few failures.

またロック部材がドアロック位置にある場合でも、ロック状態を外部から解除できるため、緊急時にも対応可能である。   Even when the lock member is in the door lock position, the locked state can be released from the outside, so that it is possible to cope with an emergency.

以下本発明の実施例を図面を参考に具体的に説明する。
先ず主として図１を用いて本発明に係るスライド型ロック装置の全体的な構造を説明する。図中符号１はドアの内側に設置されるスライド型ロック装置本体（以下単に「装置本体」とする）であり、２はドアを介してドア表面においてこのロック装置本体１に対向して配置固定される表示部である。 Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the overall structure of the slide type locking device according to the present invention will be described mainly with reference to FIG. In the figure, reference numeral 1 denotes a slide type lock device main body (hereinafter simply referred to as “device main body”) installed inside the door, and 2 denotes an arrangement fixed on the surface of the door facing the lock device main body 1 through the door. It is a display part.

装置本体１はドア裏面においてドアに固定される支持部３と、この支持部３に対して摺動するロック部材４とを有している。３ａ、３ｂは支持部３の一部を成す螺子筒であって、この螺子筒３ａ、３ｂの基底部内には雌螺子が形成されている。符号９は後述する昇降板駆動部材と係合しかつこの昇降板駆動部材を回動させる駆動軸である。なおロック部材４の作動、施錠・解錠等に関する構造及び作動状態は後に詳述する。   The apparatus main body 1 has a support portion 3 fixed to the door on the back surface of the door, and a lock member 4 that slides relative to the support portion 3. Reference numerals 3a and 3b denote screw cylinders forming a part of the support portion 3, and female screws are formed in the base portions of the screw cylinders 3a and 3b. Reference numeral 9 denotes a drive shaft that engages with an elevating plate driving member described later and rotates the elevating plate driving member. The structure and operating state relating to the operation, locking / unlocking, etc. of the lock member 4 will be described in detail later.

一方表示部２は、前記装置本体１の支持部３と対向する位置でドア表面において固定される固定部５と、この固定部５内で昇降動作する昇降板６と、この昇降板６を昇降動作させる昇降板駆動部材７の一部を成す駆動板７ａと、固定部５に対して取り付けられるカバー部材８とからなっている。   On the other hand, the display unit 2 includes a fixing unit 5 fixed on the door surface at a position facing the support unit 3 of the apparatus main body 1, an elevating plate 6 that moves up and down in the fixing unit 5, and elevating and lowering the elevating plate 6. The driving plate 7a is a part of the lift plate driving member 7 to be operated, and the cover member 8 is attached to the fixed portion 5.

次に図１の外に図２及び図３も含めてドアに対する本装置の取り付け状態について説明する。
装置の取り付けに当たっては、ロック装置が取り付けられる位置において、ドアに対して螺子筒３ａ、３ａ及び駆動軸９が挿通するための穴を３本形成しておく。この場合両側の穴の径は螺子筒３ａ、３ａが挿通可能な大きさとし、かつ中央の穴は昇降板駆動部材７の軸部７ｂが挿通しかつ、当該軸部７ｂが回動可能な程度の大きさとしておく。例えば軸部７ｂの外径が１０ｍｍであるとすると、穴の径は１１ｍｍ程度としておく。因に、両側の穴は螺子筒３ａ、３ａが挿通可能であれば良く、例えば螺子筒３ａ、３ａの外径が１０ｍｍであれば、穴の内径も１０ｍｍ程度でよい。 Next, the attachment state of this apparatus with respect to a door is demonstrated including FIG.2 and FIG.3 besides FIG.
In attaching the device, three holes for inserting the screw cylinders 3a, 3a and the drive shaft 9 into the door are formed at the position where the lock device is attached. In this case, the diameter of the holes on both sides is such that the screw cylinders 3a and 3a can be inserted, and the shaft hole 7b of the elevating plate driving member 7 is inserted in the center hole so that the shaft part 7b can rotate. Keep the size. For example, if the outer diameter of the shaft portion 7b is 10 mm, the diameter of the hole is about 11 mm. Incidentally, the holes on both sides only need to be able to be inserted into the screw cylinders 3a, 3a. For example, if the outer diameter of the screw cylinders 3a, 3a is 10 mm, the inner diameter of the holes may be about 10 mm.

以上の状態で、支持部３の螺子筒３ａ、３ａ及び駆動軸９が所定の穴を挿通してドアの表面に突出したならば固定部５に形成されている係合筒５ａ、５ａ（図示の状態では一方の係合筒５ａのみが表示されている）を各螺子筒３ａ、３ａに挿通する。因に各螺子筒３ａ、３ａは係合筒５ａ、５ａよりも長く形成され、この結果厚さの異なるドアに対してもその挿通深さを変えることにより対応することができるよう構成されている。この状態で中央の駆動軸９はドアに形成された穴及び固定部５の挿通穴５ｂを介してドア外部に突出位置する。   In the above state, if the screw cylinders 3a, 3a and the drive shaft 9 of the support portion 3 are inserted through predetermined holes and protrude from the surface of the door, engagement cylinders 5a, 5a (illustrated) formed on the fixed portion 5 are formed. In this state, only one of the engagement cylinders 5a is displayed) is inserted into the screw cylinders 3a and 3a. The screw cylinders 3a and 3a are formed longer than the engagement cylinders 5a and 5a. As a result, the doors having different thicknesses can be accommodated by changing the insertion depth. . In this state, the central drive shaft 9 protrudes outside the door through a hole formed in the door and an insertion hole 5b of the fixing portion 5.

上記の状態で、係合筒５ａを介してビス１０を挿通し螺子筒３ａ基部に形成された雌螺子部と当該ビス１０を螺合することによりドアを介して固定部５と本体部１とを固定し、両者を一体化させる。次に固定部５内に昇降板６を配置すると共に昇降板駆動部材７の軸部７ｂを、駆動軸９に対して挿通する。図示の場合は支持部３に対してロック部材が最前進位置にあり、ドアロック状態（後述する）となっているため、駆動軸９に対する昇降板駆動部材７の取り付けは、駆動板７ａが図示の如く起立している状態で当該昇降板駆動部材７を駆動軸９に嵌挿固定する。   In the above-described state, the screw 10 is inserted through the engaging cylinder 5a, and the female screw part formed on the base of the screw cylinder 3a and the screw 10 are screwed together to fix the fixing part 5 and the main body part 1 through the door. Is fixed, and both are integrated. Next, the elevating plate 6 is disposed in the fixed portion 5 and the shaft portion 7 b of the elevating plate driving member 7 is inserted into the driving shaft 9. In the illustrated case, since the lock member is at the most advanced position with respect to the support portion 3 and is in a door lock state (described later), the drive plate 7a is attached to the lift shaft drive member 7 to the drive shaft 9. The elevating plate driving member 7 is fitted and fixed to the driving shaft 9 in the state of standing up like this.

固定部５と支持部３とが固定され、装置全体がドアに取り付けられたならば固定部５に対してカバー部材８を取り付け、ビス１１、１１を固定部５に螺合することによりカバー部材８を固定し装置の取り付けを完了する（図３も合わせて参照）。   When the fixed portion 5 and the support portion 3 are fixed and the entire apparatus is attached to the door, the cover member 8 is attached to the fixed portion 5, and the screws 11 and 11 are screwed into the fixed portion 5 to cover the cover member. 8 is fixed and the installation of the apparatus is completed (see also FIG. 3).

次に装置の作動状態を内部機構の構成と共に説明する。
図４において、符号１２はロック部材４内に配置された引張型のコイルばねであって、一端は同ロック部材４側に設けられた係止爪４ａに接続し、他端は支持部３側に設けられた係止爪３ｂに接続している。これによりロック部材４は施錠を解除する方向（図４のＢ１方向）に移動するよう付勢されている。 Next, the operation state of the apparatus will be described together with the structure of the internal mechanism.
In FIG. 4, reference numeral 12 denotes a tension type coil spring disposed in the lock member 4, one end connected to a locking claw 4 a provided on the lock member 4 side, and the other end to the support portion 3 side. It is connected to the locking claw 3b provided in the. As a result, the lock member 4 is urged to move in the unlocking direction (direction B1 in FIG. 4).

符号１３はロック部材の固定手段の一部を成すラッチであり、支点１４を中心として揺動するよう構成され、常時は弾発型のコイルバネ１５により係合部１３ａがＣ１方向に回動位置するよう付勢されている。また符号１６は解錠ボタンである。なお、図中符号Ｄはロック装置の取り付け対象であるドアを示し、符号ＷＬはこのドアＤに隣接する壁部であって、この壁部ＷＬにはロック位置にあるロック部材４のピン係合部４ｂが係合する係合ピン１８が設けられている。   Reference numeral 13 denotes a latch that forms a part of the fixing means for the lock member, and is configured to swing around the fulcrum 14. The engaging portion 13 a is normally rotated in the C 1 direction by a resilient coil spring 15. It is energized as follows. Reference numeral 16 denotes an unlock button. In addition, the code | symbol D shows the door which is the attachment object of a locking device in a figure, and the code | symbol WL is a wall part adjacent to this door D, Comprising: Pin engagement of the lock member 4 in a locking position is attached to this wall part WL. An engagement pin 18 with which the portion 4b is engaged is provided.

以上の構成において、ドアＤをロックする場合にはロック部材４をコイルばね４ａの引張力に抗してＡ１方向に移動させる。この移動により支持部３に突設された係止体３ｃにラッチ１３が近接するとラッチ１３の斜面部１３ｂは支持部３に突設された係止体３ｃを乗り越え、更に移動するとコイルバネ１５の弾発力により再度Ｃ１方向に回動し、ラッチ１３の係合部１３ａと前記係止体３ｃとが係合し、ロック部材４はこの位置で固定される。ロック部材４が固定された位置において当該ロック部材のピン係合部４ｂは壁部ＷＬに固定された係止ピン１８に係止し、これによりドアＤはロック部材４により壁部ＷＬに固定ロックされる。   In the above configuration, when locking the door D, the lock member 4 is moved in the A1 direction against the tensile force of the coil spring 4a. When the latch 13 comes close to the locking body 3c projecting from the support portion 3 by this movement, the inclined surface portion 13b of the latch 13 gets over the locking body 3c projecting from the support section 3, and when the latch 13 moves further, the spring of the coil spring 15 is moved. It is rotated again in the C1 direction by the generated force, the engaging portion 13a of the latch 13 and the locking body 3c are engaged, and the lock member 4 is fixed at this position. At the position where the lock member 4 is fixed, the pin engaging portion 4b of the lock member is locked to the lock pin 18 fixed to the wall portion WL, and thereby the door D is fixedly locked to the wall portion WL by the lock member 4. Is done.

またロックを解除する場合には解錠ボタン１６を押す。この解錠ボタン１６を押すことによりラッチ１３の係合部１３ａはＣ２方向に回動し、係止体３ｃとラッチ１３との係合状態が解除され、続いてコイルばね１２の収縮によりロック部材４はＢ１方向に自動的に戻りドアＤのロックが解除される。   In order to release the lock, the unlock button 16 is pressed. When the unlocking button 16 is pressed, the engaging portion 13a of the latch 13 is rotated in the C2 direction, the engaged state between the latching body 3c and the latch 13 is released, and then the lock member is contracted by the contraction of the coil spring 12. 4 automatically returns in the B1 direction and the door D is unlocked.

一方、このロック部材４の動作に対応して表示部は以下のような作動をする。
先ず、ロック部材４が解錠状態、即ちＢ１方向に位置するときは、表示部内の駆動板７ａはＢ２方向に回動して寝た状態となっており〔図６（Ａ）参照〕、従って昇降板６は自重により下降した状態となっている。これによりカバー部材８の窓８ａには固定部５に表示されている「ＯＰＥＮ」の文字が示されることになる。 On the other hand, the display unit operates as follows in response to the operation of the lock member 4.
First, when the lock member 4 is in the unlocked state, that is, positioned in the B1 direction, the drive plate 7a in the display unit is in the state of rotating and sleeping in the B2 direction (see FIG. 6A). The elevating plate 6 is lowered by its own weight. As a result, the letters “OPEN” displayed on the fixed portion 5 are displayed on the window 8 a of the cover member 8.

続いて、ロック部材４をＡ１の方向に移動させるとロック位置でロック部材４に設けた係止体４ｄに対して駆動軸９の端部に形成された係合体１７が係止し、かつ更なるＡ１方向への移動により回転し、ロック部材４によるドアＤのロックと共に、駆動体９に接続する昇降板駆動部材７の移動板７ａをＡ２方向に回動起立させる。これにより昇降板６は図６（Ｂ）に示すように上昇し、カバー部材８の窓８ａには「ＣＬＯＳＥ」の文字が表示される。   Subsequently, when the lock member 4 is moved in the direction of A1, the engagement body 17 formed at the end of the drive shaft 9 is engaged with the engagement body 4d provided on the lock member 4 at the lock position, and further. The moving plate 7a of the elevating plate driving member 7 connected to the driving body 9 is turned upright in the A2 direction together with the locking of the door D by the locking member 4 and the rotation in the A1 direction. As a result, the elevating plate 6 is raised as shown in FIG. 6B, and the characters “CLOSE” are displayed on the window 8 a of the cover member 8.

また解錠ボタン１６を押してロック部材４による施錠を解除するときは、ロック部材４がＢ１方向に移動し、最後退位置に至る時に前記係合体１７がロック部材４の係止体４ｅに係止しかつ最後退位置に至る際に駆動板７ａをＢ２方向に回動させ、これにより図６（Ａ）に示すように昇降板６は自重により下降し、カバー部材８の窓８ａには再度「ＯＰＥＮ」の文字が表示される。   When the unlocking button 16 is pressed to release the locking by the locking member 4, the locking member 4 moves in the B1 direction, and the engaging body 17 is locked to the locking body 4e of the locking member 4 when reaching the last retracted position. When the final retracted position is reached, the drive plate 7a is rotated in the B2 direction. As a result, the lift plate 6 is lowered by its own weight as shown in FIG. “OPEN” is displayed.

次に、非常時の施錠状態解除について説明する。
昇降板駆動部材７、この昇降板駆動部材７が連設する駆動軸９は何れも中空になっており、ドアＤがロックされている状態で緊急に解錠したい場合には、針金或いは専用の解除ピンをカバー部材８の挿通穴８ｂ、昇降板駆動部材７の挿通穴７ｃ、駆動軸９の挿通穴９ａを挿通させる。ロック部材４がドアＤをロックしている状態では、ラッチ１３（図４において符号１３´示す）の平面部１３ｃがこの挿通穴９ａの開口部に位置している。このため、針金やピンを押し込むことによりこれら針金やピンの先端がラッチ１３の平面部１３ｃを押圧し、これによりラッチ１３はコイルばね１５の弾発力に抗してＣ２方向に回動し、係止体３ｃとの係合状態が解除される。係合状態の解除によりコイルばね１２の収縮力によってロック部材４は自動的にＢ１方向に移動しドアＤのロックが解除される。 Next, the unlocking state cancellation at the time of emergency will be described.
The elevating plate driving member 7 and the drive shaft 9 connected to the elevating plate driving member 7 are both hollow, and when it is necessary to urgently unlock the door D in a locked state, a wire or a dedicated drive shaft 9 is used. The release pin is inserted through the insertion hole 8 b of the cover member 8, the insertion hole 7 c of the lifting plate driving member 7, and the insertion hole 9 a of the drive shaft 9. In a state where the lock member 4 locks the door D, the flat surface portion 13c of the latch 13 (indicated by reference numeral 13 'in FIG. 4) is positioned at the opening of the insertion hole 9a. For this reason, by pushing the wire or pin, the tip of the wire or pin presses the flat surface portion 13c of the latch 13, whereby the latch 13 rotates in the C2 direction against the elastic force of the coil spring 15, The engaged state with the locking body 3c is released. When the engagement state is released, the lock member 4 is automatically moved in the B1 direction by the contraction force of the coil spring 12, and the door D is unlocked.

なお、作動の確実性はやや低下するものの、平面部１３ｃを無くしてラッチ１３の構成を単純化し、ラッチ１３の斜面部１３ｂが挿通穴９ａの開口部に位置するよう構成して、この斜面部１３ｂを押圧するよう構成することも可能である。   Although the reliability of the operation is slightly lowered, the configuration of the latch 13 is simplified by eliminating the flat surface portion 13c, and the slope portion 13b of the latch 13 is positioned at the opening portion of the insertion hole 9a. It is also possible to configure to press 13b.

上記実施例では表示部２における施錠・解錠の状態を「ＣＬＯＳＥ」、「ＯＰＥＮ」の英語表示としたが、「開」、「閉」等の日本語表示としたり、あるいは開を青、閉を赤など色で表示する等各種の表示方法が実施可能である。   In the above embodiment, the lock / unlock state of the display unit 2 is displayed in English such as “CLOSE” and “OPEN”, but it can be displayed in Japanese such as “open” and “closed”, or open is blue and closed. Various display methods such as displaying red in a color such as red can be implemented.

上記各実例ではロック装置をトイレ等の家庭用を例に説明したが、施錠、解錠に大きな力を必要とせず、かつ作動部分が摺動を中心とした比較的単純な作動であるため、埃や粉塵等が生じる作業空間での利用も可能である。研究室等、頻繁に部外者が出入りすることを好まないような空間での施錠、及び室内での緊急事態に対応して外部から解錠する必要がある場合等、施錠の確実性と安全性の両方を両立させる必要がある分野で幅広く利用可能である。   In each of the above examples, the locking device has been described as an example for household use such as a toilet, but since a large force is not required for locking and unlocking, and the operation part is a relatively simple operation centering on sliding, It can also be used in a work space where dust or dust is generated. Locking certainty and safety when locked in a space where outsiders do not like frequent entrances and exits, and when it is necessary to unlock from the outside in response to an emergency in the room It can be widely used in fields where both sexes need to be compatible.
