Description

本発明は、例えば引戸錠に好適で、防御能力を向上し、不正な解錠操作を阻止し得るとともに、ドアまたは枠体との取り付け精度や、構成部材の寸法精度を要することなく、容易かつ安価に製作でき取り付けられるドア錠に関する。 The present invention is suitable for, for example, sliding door locks, can improve defense capability and prevent unauthorized unlocking operation, and can be easily and without requiring accuracy of attachment to a door or a frame or dimensional accuracy of components. It relates to door locks that can be manufactured inexpensively and attached.

例えば引戸錠として、扉の自由端部に錠箱を取り付け、該錠箱内に鉤部を有するラッチ体を上下方向に回動可能に設け、該ラッチ体を軸支するスライダ−を上下動可能に設け、該スライダ−に中間レバ−の一端をピン連結し、その他端をトリガ−体に係合可能に配置し、前記トリガ−体を錠箱のフロント板から突出可能に付勢し、その突出端部を扉枠に当接可能に配置する一方、扉枠の内部にトロヨケを設け、該トロヨケの開口側に係止孔を有するストライク板を配置したものがある。 For example, as a sliding door lock, a lock box is attached to the free end of the door, a latch body having a collar is provided in the lock box so as to be pivotable in the vertical direction, and a slider that supports the latch body can be moved up and down. The intermediate lever is pin-connected to the slider, the other end is arranged to be engageable with the trigger body, and the trigger body is urged to protrude from the front plate of the lock box. In some cases, the protruding end portion is disposed so as to be able to contact the door frame, while a trowel is provided inside the door frame, and a strike plate having a locking hole is disposed on the opening side of the trowel.

前記引戸錠は、開扉時にトリガ−体をフロント板から突出し、スライダ−に連結したラッチ体を錠箱内に位置付け、閉扉時にトリガ−体を扉枠に当接させ、該トリガ−体を錠箱内に押し込んで中間レバ−を回動させ、スライダ−をフロント板側へ移動し、これにラッチ体を同動させて、ラッチ体の鉤部をストライク板の係止孔の口縁部に係合し、閉扉状態を維持させていた。
一方、開扉時にラッチ体の直上に配置した解除部材を操作し、該解除部材をラッチ体の他端部に係合させ、該ラッチ体を上向きに回動して、前記鉤部と係止孔との係合を解除し、開扉していた（例えば、特許文献１参照）。 In the sliding door lock, the trigger body protrudes from the front plate when the door is opened, the latch body connected to the slider is positioned in the lock box, the trigger body abuts against the door frame when the door is closed, and the trigger body is locked. Push in the box to rotate the intermediate lever, move the slider to the front plate side, move the latch body to this, and move the latch body to the edge of the strike hole of the strike plate The doors were engaged and kept closed.
On the other hand, when the door is opened, the release member disposed immediately above the latch body is operated, the release member is engaged with the other end portion of the latch body, the latch body is rotated upward, and is engaged with the flange portion. The engagement with the hole was released and the door was opened (for example, see Patent Document 1).

しかし、前記引戸錠は、ラッチ体の鉤部をストライク板の係止孔に係合して施錠しているため、例えば扉と扉枠の間に薄厚の不正器具を差し込んで引き上げると、前記鉤部と係止孔との係合が解除されて解錠され、開扉される惧れがあった。
しかも、前記引戸錠は、施錠時の異音の発生を防止するため、鉤部と係止孔との係合時の間隙をなるべく小さくする必要があり、そのために扉と扉枠の取り付け精度や、構成部品の寸法精度を高める必要があり、結果的に製造コストが上昇する問題があった。 However, since the sliding door lock is locked by engaging the hook portion of the latch body with the engaging hole of the strike plate, for example, when a thin improper instrument is inserted between the door and the door frame and pulled up, There is a concern that the engagement between the portion and the locking hole is released, the door is unlocked, and the door is opened.
In addition, the sliding door lock needs to reduce the gap at the time of engagement between the collar portion and the locking hole as much as possible in order to prevent the generation of noise during locking. Therefore, it is necessary to increase the dimensional accuracy of the component parts, resulting in a problem that the manufacturing cost increases.

前記問題を解決するものとして、引戸の下部框の一端部側面に操作部材を回動可能に設け、前記下部框に錠ケ−スを設け、該錠ケ−ス内に前記操作部材に同動可能なダルマを回動可能に設け、該ダルマに第１および第２駆動ア−ムを突設し、一方、引戸の移動域の床面にストライクを設け、該ストライクの係合凹所に係脱可能なデッドボルトを前記ダルマの近接位置に取り付け、前記デッドボルトを上位デッドボルトと下位デッドボルトとで伸縮可能に連結したものがある。 In order to solve the above problem, an operation member is rotatably provided on one side surface of the lower side of the sliding door, a lock case is provided on the lower side, and the operation member moves in the lock case. A movable dharma is rotatably provided, and the first and second drive arms are protruded from the dharma, while a strike is provided on the floor surface of the moving area of the sliding door, and the engaging recess of the strike is engaged. There is a type in which a detachable dead bolt is attached to a position close to the dharma, and the dead bolt is connected to an upper dead bolt and a lower dead bolt so as to extend and contract.

そして、下位デッドボルトに設けた係合ア−ムと前記第２駆動ア−ムを係合可能に配置し、前記デッドボルトを錠ケ−ス内では収縮し、施錠時にダルマを施錠方向に回動してデッドボルトを伸長し、該デッドボルトをストライクの係合凹所へ係合し、引戸を持ち上げてもデッドボルトをストライクから容易に外れないようにしていた（例えば、特許文献２参照）。 Then, the engagement arm provided on the lower deadbolt and the second drive arm are arranged to be engageable, the deadbolt is contracted in the lock case, and the dharma is rotated in the locking direction at the time of locking. The dead bolt is moved to extend, and the dead bolt is engaged with the engagement recess of the strike so that the dead bolt is not easily detached from the strike even when the sliding door is lifted (see, for example, Patent Document 2). .

しかし、前記引戸錠は、デッドボルトを単に伸長して閂状に形成し、これをストライクの係合凹所に係合させているため、引戸をデッドボルトの係合代以上に持ち上げると、実質的に解錠され開扉される惧れがあり、しかも構造が複雑で製造コストが高価になるという問題があった。 However, the sliding door lock is simply formed by extending the dead bolt into a hook shape and engaging it with the engagement recess of the strike. There is a risk that the door is unlocked and the door is opened, and the structure is complicated and the manufacturing cost is high.

また、前記問題を解決するものとして、ドアの端面から出没するラッチボルトの頭部に磁石を挿入したマグネットケ−スを設け、また框に設けたストライクボックスの底部に磁石とマグネットカバ−を設け、施錠時に双方の磁石の吸引作用によって、ストライクボックスにラッチボルトの頭部を吸着するようにしたドア錠がある（例えば、特許文献３参照）。 In addition, as a solution to the above problem, a magnet case in which a magnet is inserted is provided at the head of a latch bolt that protrudes and protrudes from the end face of the door, and a magnet and a magnet cover are provided at the bottom of a strike box provided in the cage. There is a door lock in which the head of the latch bolt is attracted to the strike box by the attracting action of both magnets during locking (see, for example, Patent Document 3).

しかし、前記ドア錠は、双方の磁石の吸引作用によって、施錠時の防御能力を強化できるが、磁石の吸引力には限界があり、不正な開扉を阻止することまで期待できない。 However, the door lock can reinforce the defense capability at the time of locking by the attractive action of both magnets, but there is a limit to the attractive force of the magnet, and it cannot be expected to prevent unauthorized opening.

その際、ナット７０，７１を長溝７２，７３に沿って移動することによって、受箱６をドア２の前後方向に移動調整できる。この後、ビス６９をビス孔８０に挿入し、これをドア２のネジ孔にねじ込んで緊締し、ドア２の内側に受箱６を固定する。 At this time, the receiving box 6 can be moved and adjusted in the front-rear direction of the door 2 by moving the nuts 70 and 71 along the long grooves 72 and 73. Thereafter, the screw 69 is inserted into the screw hole 80, screwed into the screw hole of the door 2 and tightened, and the receiving box 6 is fixed inside the door 2.

次に、錠本体Ｌをドア１に取り付ける場合は、前記受箱６の取り付け位置に対応するドア１の後端部にブラケット１６を位置付け、その長孔１８，２１にビス（図示略）を挿入してドア１にねじ込む。
その際、長孔１８，２１に沿ってブラケット１６を移動することによって、ドア１に対するブラケット１６の高さ位置を調整できる。 Next, when the lock body L is attached to the door 1, the bracket 16 is positioned at the rear end portion of the door 1 corresponding to the attachment position of the receiving box 6, and screws (not shown) are inserted into the long holes 18 and 21 thereof. Then screw into the door 1.
In that case, the height position of the bracket 16 with respect to the door 1 can be adjusted by moving the bracket 16 along the long holes 18 and 21.

こうして取り付けたブラケット１６に錠本体Ｌを取り付ける場合は、ブラケット１６のガイド溝１４の側方に錠本体Ｌを保持し、その係合溝２９，３０をガイド溝１４に嵌合し、その所定位置でボルト（図示略）を長孔１７に挿入し、これをネジ孔７７にねじ込んで緊締する。
その際、錠本体Ｌを長孔１７に沿って移動することによって、錠本体Ｌをドア１の内外方向へ位置調整でき、受箱６に対し近接離反調整可能になって、デッドボルト７とロックピ−ス５１との係合調整が可能になる。 When the lock body L is attached to the bracket 16 thus attached, the lock body L is held on the side of the guide groove 14 of the bracket 16, the engagement grooves 29 and 30 are fitted into the guide groove 14, and the predetermined position is set. Then, a bolt (not shown) is inserted into the long hole 17 and screwed into the screw hole 77 for tightening.
At that time, by moving the lock body L along the elongated hole 17, the position of the lock body L can be adjusted inward and outward of the door 1, and the proximity and separation of the receiving box 6 can be adjusted. -The engagement adjustment with the sleeve 51 becomes possible.

こうして取り付けた錠本体Ｌと受箱６の取り付け状況は図１のようで、ト゛ア１の後端部の上端に錠本体Ｌが取り付けられ、ドア２の前端部の上端に受箱６が取り付けられ、ドア１，２の閉扉時に錠本体Ｌと受箱６とが対向して位置する。 The state of attachment of the lock body L and the receiving box 6 thus attached is as shown in FIG. 1. The lock body L is attached to the upper end of the rear end portion of the door 1, and the receiving box 6 is attached to the upper end of the front end portion of the door 2. When the doors 1 and 2 are closed, the lock body L and the receiving box 6 are opposed to each other.

このようなドア錠において、その解錠時は図４および図６のように、デッドボルト７が錠本体Ｌの内側に移動し、ストッパ４４が錠ケ−ス４の内壁に係合するとともに、ロックカム２５の先端部が係合片４３に係合し、内側のスプリング４２の弾性に押圧されて、仕切溝２３の周壁に当接し静止している。 In such a door lock, at the time of unlocking, as shown in FIGS. 4 and 6, the dead bolt 7 moves to the inside of the lock body L, the stopper 44 engages with the inner wall of the lock case 4, The distal end portion of the lock cam 25 engages with the engagement piece 43, is pressed by the elasticity of the inner spring 42, and comes into contact with the peripheral wall of the partition groove 23 to be stationary.

一方、受箱６の内側では、ピン６３がスプリング６６の弾性によってロックピ−ス５１側へ押圧され、これにリンク６０の一端が同動して、該リンク６０に連結されたロックピ−ス５１がピン５３を中心に開口部４８側へ回動し、係合凸部５６が凸部５７に係合して静止している。したがって、このような解錠時にはドア１，２を引き動かして開扉可能になる。 On the other hand, on the inner side of the receiving box 6, the pin 63 is pressed to the lock piece 51 side by the elasticity of the spring 66, and one end of the link 60 moves along with this, and the lock piece 51 connected to the link 60 is moved. The pin 53 rotates about the pin 48 toward the opening 48, and the engaging convex portion 56 engages with the convex portion 57 and is stationary. Therefore, at the time of such unlocking, the doors 1 and 2 can be moved to open the door.

このような解錠状態からドア１，２を施錠する場合は、ドア１，２を引き動かして互いに閉扉し、錠本体Ｌと受箱６とを対向して位置付ける。
そして、キ−１１をシリンダ−錠９の鍵孔１０に差し込み、これを施錠方向へ回動すると、キ−１１の回動変位に内部のシリンダ−（図示略）が同動し、これに連結板２８が同動して、該連結板２８と係合するロックカム２５が回動する。 When the doors 1 and 2 are locked from such an unlocked state, the doors 1 and 2 are moved to close each other, and the lock body L and the receiving box 6 are positioned facing each other.
When the key 11 is inserted into the key hole 10 of the cylinder lock 9 and is rotated in the locking direction, the internal cylinder (not shown) is moved to the rotational displacement of the key 11 and connected thereto. The plate 28 moves together, and the lock cam 25 engaged with the connecting plate 28 rotates.

このため、ロックカム２５が係合片４３を介して内側のスプリング４２を押し縮め、係合片４３を頸部４１側へ押し動かすとともに、ロックカム２５がデッドボルト７の後端部に係合し、該デッドボルト７をロック金具３６と一緒に錠本体Ｌの外側へ押し動かす。 For this reason, the lock cam 25 pushes and shrinks the inner spring 42 via the engagement piece 43, pushes the engagement piece 43 toward the neck portion 41, and the lock cam 25 engages with the rear end portion of the dead bolt 7. The dead bolt 7 is pushed and moved together with the lock fitting 36 to the outside of the lock body L.

前記デッドボルト７はスライド溝２２上を摺動して錠本体Ｌの外側へ移動し、その先端部が錠本体Ｌから突出してストライク板１２の通孔１３に進入し、デッドボルト７の係合突起５４がロックピ−ス５１の係合凹部５５に係入する。この状況は図１１および図１２のようである。 The dead bolt 7 slides on the slide groove 22 and moves to the outside of the lock main body L. The tip of the dead bolt 7 protrudes from the lock main body L and enters the through hole 13 of the strike plate 12. The protrusion 54 engages with the engagement recess 55 of the lock piece 51. This situation is as shown in FIGS.

キ−１１の前記回動操作が続行され、ロックカム２５が更に回動すると、該カム２５に係合するデッドボルト７が更に外側へ移動し、その係止凸部８１が錠ケ−ス４の係止凹部８２に係合して、デッドボルト７の突出作動が停止する。
そして、前記デッドボルト７が図１１の状態から更に外側へ突出すると、係合突起５４が係合凹部５５に当接して、該カム５１を後方へ押し動かし、該ロックピ−ス５１を、ピン５３を中心に図１１上反時計方向へ回動させる。 When the rotation operation of the key 11 is continued and the lock cam 25 further rotates, the dead bolt 7 that engages with the cam 25 moves further outward, and the locking convex portion 81 of the lock case 4 Engaging with the locking recess 82 stops the projecting operation of the dead bolt 7.
When the dead bolt 7 protrudes further outward from the state of FIG. 11, the engagement protrusion 54 comes into contact with the engagement recess 55, and the cam 51 is pushed backward to move the lock piece 51 to the pin 53. Is rotated counterclockwise in FIG.

こうして、デッドボルト７が更に外側へ突出すると、係合突起５４が係合凹部５５に係合し、ロックピ−ス５１が更に後方へ押し動かされて、該カム５１がピン５３を中心に図１１上、更に反時計方向へ回動する。
このため、リンク６０の一端がロックピ−ス５１に同動して起立し、他端のピン６９が長孔６４に沿って移動して、スプリング６６をその弾性に抗して押し縮める。
この後、ロックピ−ス５１が若干回動し、リンク６０が更に起立して、スプリング６６が押し縮められる。 Thus, when the dead bolt 7 protrudes further outward, the engaging projection 54 engages with the engaging recess 55, the lock piece 51 is further pushed rearward, and the cam 51 is centered on the pin 53 as shown in FIG. Up and further counterclockwise.
For this reason, one end of the link 60 moves up together with the lock piece 51, and the pin 69 at the other end moves along the long hole 64, thereby compressing the spring 66 against its elasticity.
Thereafter, the lock piece 51 is slightly rotated, the link 60 is further raised, and the spring 66 is compressed.

そして、デッドボルト７が突出作動を停止すると、ロックカム２５の先端部がデッドボルト７の後端部のテ−パ部３５ａから離間し、一方、ロック金具３６がスプリング３４の弾性によって内側へ付勢され、前記金具３６の後端部がロックカム２５の先端部の回動域に位置して、該金具３６の後端部にロックカム２５の先端部が係合可能に位置する。 When the dead bolt 7 stops projecting, the front end portion of the lock cam 25 is separated from the taper portion 35a at the rear end portion of the dead bolt 7, while the lock fitting 36 is biased inward by the elasticity of the spring 34. Then, the rear end portion of the metal fitting 36 is positioned in the rotation region of the front end portion of the lock cam 25, and the front end portion of the lock cam 25 is positioned to be engageable with the rear end portion of the metal fitting 36.

こうして、キ−１１が更に回動操作され、ロックカム２５が更に回動すると、該カム２５の先端部がロック金具３６の後端部に係合し、該金具３６をスプリング６６の弾性に抗して外側へ押し動かす。
このため、ロック金具３６が長孔３８に沿って段部３５上を滑動し、その先端の切欠部３６ａの口縁部がロックピ−ス５１の係合凸部５６の基部に係合可能に移動し、ロックピ−ス５１の回動を阻止して、施錠状態を形成する。この状況は図１３のようである。 Thus, when the key 11 is further rotated and the lock cam 25 is further rotated, the front end portion of the cam 25 engages with the rear end portion of the lock fitting 36, and the fitting 36 resists the elasticity of the spring 66. And push outward.
For this reason, the lock fitting 36 slides on the step portion 35 along the long hole 38, and the lip portion of the notch 36a at the tip thereof moves so as to be engageable with the base portion of the engagement convex portion 56 of the lock piece 51. Then, the lock piece 51 is prevented from rotating to form a locked state. This situation is as shown in FIG.

このような施錠時には、デッドボルト７の先端部の係止突起５４と凹部３２が、受箱６の内部に配置したロックピ−ス５１の係合凹部５５と係合凸部５６に係合し、また切欠部３６ａの口縁部がロックピ−ス５１の係合凸部５６の基部に係合可能に位置して、デッドボルト７の後退動とロックピ−ス５１の回動を阻止している。 At the time of such locking, the locking projection 54 and the concave portion 32 at the tip of the dead bolt 7 engage with the engaging concave portion 55 and the engaging convex portion 56 of the lock piece 51 disposed inside the receiving box 6, Further, the edge portion of the notch 36 a is positioned so as to be engageable with the base of the engaging convex portion 56 of the lock piece 51, thereby preventing the dead bolt 7 from moving backward and the lock piece 51 from rotating.

また、デッドボルト７の後端部がロックカム２５の先端部と係合可能に位置し、ロック金具３６の後端部がロックカム２５の先端部と係合して、デッドボルト７の後退を阻止するとともに、ロックカム２５の先端部が係合片４３と係合して押圧され、その側端部が仕切壁２３に係合して静止し、前述の状態を維持している。 Further, the rear end portion of the dead bolt 7 is positioned so as to be engageable with the front end portion of the lock cam 25, and the rear end portion of the lock fitting 36 is engaged with the front end portion of the lock cam 25, thereby preventing the dead bolt 7 from retreating. At the same time, the distal end portion of the lock cam 25 is engaged with the engagement piece 43 and pressed, and the side end portion engages with the partition wall 23 to be stationary and maintains the above-described state.

したがって、ドア１，２の間に不正器具を挿入して、デッドボルト７の先端部とロックピ−ス５１の係合を解除することは事実上困難になり、またキ−操作以外にロックカム２５を解錠回動させることも事実上困難であるから、高い防御能力を奏する。 Therefore, it becomes practically difficult to disengage the distal end portion of the dead bolt 7 and the lock piece 51 by inserting an improper instrument between the doors 1 and 2, and the lock cam 25 can be used in addition to the key operation. It is also difficult to unlock and rotate, so it has a high defense ability.

このような施錠状態を解錠する場合は、キ−１１をシリンダ−錠９の鍵孔１０に挿入し、これを解錠方向へ回動する。
このようにすると、キ−１１の回動変位に内部のシリンダ−（図示略）が同動し、これに連結板２８が同動して、該連結板２８と係合するロックカム２５が、図１３上時計方向へ回動する。 When unlocking such a locked state, the key 11 is inserted into the key hole 10 of the cylinder lock 9 and rotated in the unlocking direction.
In this way, the internal cylinder (not shown) is moved to the rotational displacement of the key 11, and the connecting plate 28 is moved to the lock plate 25 to be engaged with the connecting plate 28. 13 Turn clockwise.

このため、ロックカム２５の先端部が係合片４３を押圧し、内側のスプリング４２を押し縮めて、係合片４３を頸部４１方向へ押し動かし、一方、前記ロックカム２５の回動分、ロック金具３６がスプリング３３の弾性によってロックカム２５側へ引き戻され、切欠部３６ａの口縁部がロックピ−ス５１の係合凸部５６の基部から後退して、ロックピ−ス５１を回動可能に形成する。 For this reason, the front end portion of the lock cam 25 presses the engagement piece 43, and the inner spring 42 is pressed and contracted to push and move the engagement piece 43 toward the neck portion 41. The metal fitting 36 is pulled back toward the lock cam 25 by the elasticity of the spring 33, and the edge of the notch 36a is retracted from the base of the engaging projection 56 of the lock piece 51 so that the lock piece 51 can be rotated. To do.

この後、キ−１１が更に回動操作され、ロックカム２５が前述と同方向へ回動すると、ロックカム２５の先端部が係合ア−ム３１に係合し、該ア−ム３１を介してデッドボルト７を図１３上右方へ押し動かし、該デッドボルト７を錠本体Ｌの内側へ引き戻して、その先端部を受箱６から引き抜く。 Thereafter, when the key 11 is further rotated and the lock cam 25 is rotated in the same direction as described above, the tip end portion of the lock cam 25 is engaged with the engagement arm 31 and the arm 31 is interposed therebetween. The dead bolt 7 is pushed and moved rightward in FIG. 13, the dead bolt 7 is pulled back to the inside of the lock body L, and the tip portion is pulled out from the receiving box 6.

こうしてデッドボルト７が受箱６から後退すると、その係止突起５４と凹部３２に係合する係合凹部５５と係合凸部５６を介して、ロックピ−ス５１がピン５３を中心に図１３上時計方向へ回動し、該カム５１と同動するピン５９を介して、リンク６０の一端が引き動かされ、他端のピン６３が長溝６４に沿って移動して傾倒変位する。 When the dead bolt 7 is retracted from the receiving box 6 in this manner, the lock piece 51 is centered on the pin 53 through the engaging protrusion 55 and the engaging convex portion 56 engaged with the concave portion 32 as shown in FIG. One end of the link 60 is pulled through the pin 59 that rotates in the clockwise direction and moves together with the cam 51, and the pin 63 at the other end moves along the long groove 64 and is tilted and displaced.

こうしてキ−１１が更に回動操作され、ロックカム２５が前述と同方向へ回動すると、
前記ロックカム２５の回動分、デッドボルト７が錠本体Ｌの内側へ移動し、その後端部がスライド溝２２の奥部へ移動し、先端部が受箱６から引き抜かれて、ドア１，２の間に空隙が形成されて解錠され、この後ドア１，２を開扉することができる。この状況は図４のようである。 Thus, when the key-11 is further rotated and the lock cam 25 is rotated in the same direction as described above,
The dead bolt 7 is moved to the inside of the lock main body L by the amount of rotation of the lock cam 25, the rear end portion is moved to the inner portion of the slide groove 22, the front end portion is pulled out from the receiving box 6, and the doors 1, 2 A space is formed between the doors 1 and 2 and the doors 1 and 2 can be opened. This situation is as shown in FIG.

このように本発明は、錠本体Ｌと受箱６の双方の内部機構によって、確実かつ安定した施解錠作動と、強力な防御能力を実現したものである。 As described above, the present invention realizes a reliable and stable locking / unlocking operation and a strong defense capability by the internal mechanisms of both the lock body L and the receiving box 6.

このように本発明のドア錠は、防御能力を向上し、不正な解錠操作を阻止し得るとともに、ドアまたは枠体との取り付け精度や、構成部材の寸法精度を要することなく、容易かつ安価に製作でき取り付けられるから、例えば引戸錠に好適である。 As described above, the door lock of the present invention improves the defense capability and can prevent unauthorized unlocking operation, and is easy and inexpensive without requiring the accuracy of attachment to the door or the frame or the dimensional accuracy of the components.
