前記操作部材を押しボタンとした框内蔵型施錠装置は、ラック歯を有する押しボタンを押し込んで前記ラック歯に噛合する中間歯車を回転させ、該中間歯車に噛合する歯車が形成された掛け具を受け具に係合させて施錠し、解錠する際には、前記施錠状態から押しボタンをさらに押し込んでストッパー機構を解除するとともに、外召合せ框内の圧縮コイルばねを変形させた復元力により押しボタンを室内側へ押し戻しながら掛け具を受け具から外すように構成されている。
したがって、押しボタンのワンタッチ操作により施解錠を行う構成であるため、操作性の向上については一定の効果があるものであるが、押しボタンを押し込んで圧縮コイルばねを変形させ、その復元力により解錠状態に復帰させる構成であるため、摺動摩擦の大きさの変動等により動作が不確実・不安定になる場合がある。例えば、圧縮コイルばねの付勢力によって付勢された押しボタンが解錠状態となる位置まで復帰せずに途中で止まってしまった場合には、この押しボタンを引き戻して解錠状態にするよう操作する必要がある。
また、外召合せ框内の圧縮コイルばねを変形させる必要があることから、押しボタンのストロークが大きくなるため、内召合せ框から室内側への押しボタンの突出量が大きくなる(例えば、特許文献1の図8(a)参照。)。
The locking device with a built-in hook using the operation member as a push button pushes a push button having rack teeth, rotates an intermediate gear meshing with the rack teeth, and has a hook formed with a gear meshing with the intermediate gear. When locking and unlocking by engaging with the receiving tool, the push button is further pushed from the locked state to release the stopper mechanism, and the compression coil spring in the outer summoning cage is used to restore the force. The hanging tool is configured to be removed from the receiving tool while pushing the push button back to the indoor side.
Therefore, since it is configured to lock and unlock by one-touch operation of the push button, there is a certain effect in improving operability, but the compression coil spring is deformed by pushing the push button and unlocked by its restoring force. Since it is configured to return to the locked state, the operation may be uncertain or unstable due to fluctuations in the magnitude of sliding friction. For example, if the push button biased by the biasing force of the compression coil spring stops before returning to the unlocked position, the push button is pulled back to the unlocked state. There is a need to.
Moreover, since it is necessary to deform the compression coil spring in the outer summon basket, the stroke of the push button becomes larger, so that the push button protrudes from the inner summit basket to the indoor side (for example, patent) (Refer FIG. 8 (a) of the literature 1.).

そこで本発明が前述の状況に鑑み、解決しようとするところは、押しボタンによる施解錠動作を確実にかつ安定して行うことができ、内召合せ框から室内側への押しボタンの突出量が大きくなることがないためすっきりとした滑らかな外観にすることができる框内蔵型施錠装置を提供する点にある。   Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the locking / unlocking operation by the push button can be performed reliably and stably, and the protrusion amount of the push button from the inner summit bowl to the indoor side is small. The object of the present invention is to provide a lock device with a built-in scissors that can be made clean and smooth because it does not become large.

本発明に係る框内蔵型施錠装置は、前記課題解決のために、枠体内に配置された複数の障子の少なくとも一つを見付け方向にスライドさせて開口部を開閉する引き形式のサッシ窓において、該サッシ窓を閉じた状態で内外の召合せ框間を施錠する框内蔵型施錠装置であって、室内側障子の内召合せ框内又は前記内召合せ框及びその室内側に突設されたケース内に収容された錠本体の掛け具を、室外側障子の外召合せ框の室内側に露出した受け具に係合させて施錠するものであり、前記錠本体に、見付け方向支軸まわりに回転可能に支持された中間歯車と、該中間歯車の上下に噛合する下ラック歯及び上ラック歯がそれぞれの下面及び上面に形成され、見込み方向に直動可能に支持され、それぞれが逆方向に進退する上下一対のラック体と、これらラック体の中の、上側ラック体の上面に形成された上ラック歯又は下側ラック体の下面に形成された下ラック歯に噛合する歯車が設けられ、その見付け方向支軸まわりに回動可能に支持された前記掛け具と、前記上下のラック体の室内側に装着又は前記ラック体と一体に形成された上下の押しボタンとを備え、前記上側ラック体の上面又は前記下側ラック体の下面に対して、前記錠本体により上下方向に直動可能に支持された係合部材を弾性付勢し、前記上下の押しボタンの一方を操作して施錠した際に前記係合部材が係合する係合凹部を、前記上側ラック体の上面又は前記下側ラック体の下面に形成するとともに、前記係合部材を前記弾性付勢力に抗して移動させる操作片を前記内召合せ框の室内側に設けてなることを特徴とする。 In order to solve the above-mentioned problem, the lock device with a built-in hook according to the present invention is a pull-type sash window that opens and closes an opening by sliding at least one of a plurality of shojis arranged in a frame in the direction of finding, A locking device with a built-in lock that locks the inner and outer summits with the sash window closed, and is provided in the inner summoning box of the indoor side shoji or in the inner summoning box and the indoor side. The lock body of the lock body accommodated in the case is locked by engaging with a receiver exposed to the indoor side of the outside sump of the outdoor shoji. An intermediate gear that is rotatably supported, and a lower rack tooth and an upper rack tooth that mesh with the upper and lower sides of the intermediate gear are formed on the lower surface and the upper surface of the intermediate gear, and are supported so as to be linearly movable in the prospective direction. A pair of upper and lower rack bodies that move forward and backward A gear that meshes with the upper rack teeth formed on the upper surface of the upper rack body or the lower rack teeth formed on the lower surface of the lower rack body is provided in the rack body, and is rotated around the supporting direction support shaft. The hanger supported so as to be supported on the indoor side of the upper and lower rack bodies or the upper and lower push buttons formed integrally with the rack body, the upper surface of the upper rack body or the lower rack body. An engagement member supported by the lock body so as to be linearly movable in the vertical direction is elastically biased against the lower surface of the lock, and the engagement member is engaged when one of the upper and lower push buttons is locked. A mating engagement recess is formed on the upper surface of the upper rack body or the lower surface of the lower rack body, and an operation piece for moving the engagement member against the elastic urging force is provided on the inner summit bowl. It is provided on the indoor side .

このような構成によれば、見込み方向に直動可能に支持された上下一対のラック体が見付け方向支軸まわりに回転可能に支持された中間歯車を介して逆方向に進退することから、一方のラック体の押しボタン(閉ボタン)を室外方向へ押すと、受け具に係合するように掛け具が回動して施錠状態となり、この施錠状態から他方のラック体の押しボタン(開ボタン)を室外方向へ押すと、受け具との係合を解除するように掛け具が回動して解錠状態となる。
よって、上下個別の押しボタンのワンタッチ操作により施解錠を行うことができるため、押しボタンによる施解錠動作を確実にかつ安定して行うことができるとともに操作性を向上することができる。
その上、特許文献1のように1個の押しボタンを2段階に押し込んで施解錠をする構成のように押し込みストロークを大きくする必要がないことから、内召合せ框から室内側へ押しボタンが大きく突出することがないため、すっきりとした滑らかな外観にすることが容易である。
According to such a configuration, the pair of upper and lower rack bodies supported so as to be linearly movable in the prospective direction moves forward and backward in the reverse direction via the intermediate gear supported so as to be rotatable about the finding direction support shaft. When the push button (close button) of the rack body is pushed in the outdoor direction, the hook is rotated so as to be engaged with the receiver and is locked, and the push button (open button) of the other rack body is moved from this locked state. ) In the outdoor direction, the hook is rotated so as to be disengaged from the receiver, and is unlocked.
Therefore, since locking / unlocking can be performed by one-touch operation of the upper and lower individual push buttons, the locking / unlocking operation by the push buttons can be performed reliably and stably and the operability can be improved.
In addition, since there is no need to increase the push-in stroke as in the configuration in which one push button is pushed into two stages as in Patent Document 1, and the lock is unlocked, there is a push button from the summon bowl to the indoor side. Since it does not protrude greatly, it is easy to achieve a clean and smooth appearance.

その上さらに、前記上側ラック体の上面又は前記下側ラック体の下面に対して、前記錠本体により上下方向に直動可能に支持された係合部材を弾性付勢し、前記上下の押しボタンの一方を操作して施錠した際に前記係合部材が係合する係合凹部を、前記上側ラック体の上面又は前記下側ラック体の下面に形成するとともに、前記係合部材を前記弾性付勢力に抗して移動させる操作片を前記内召合せ框の室内側に設けてなるので、施錠状態では係合部材が係合凹部に係合することから押しボタン(開ボタン)を押すことができないロック状態となるため防犯性が高くなる。
その上、操作片により係合部材を弾性付勢力に抗して移動させることができるため、解錠する際には、操作片を操作して係合部材を係合凹部から外した状態とした後に、押しボタン(開ボタン)のワンタッチ操作により解錠することができる。
その上さらに、内召合せ框の室内側に設けた操作片の位置を視認して施解錠状態を認識することができるため、施錠忘れ防止効果が高くなる。
Furthermore, the upper and lower pushbuttons are elastically biased with respect to the upper surface of the upper rack body or the lower surface of the lower rack body and supported by the lock body so as to be movable in the vertical direction. An engaging recess is formed on the upper surface of the upper rack body or the lower surface of the lower rack body, and the engaging member is elastically attached. Since the operation piece to be moved against the force is provided on the indoor side of the inner summit bowl, the push button (open button) can be pushed because the engagement member is engaged with the engagement recess in the locked state. Because it becomes a locked state that can not be done, crime prevention becomes high.
In addition, since the engagement member can be moved against the elastic biasing force by the operation piece, when unlocking, the operation piece is operated to remove the engagement member from the engagement recess. Later, it can be unlocked by one-touch operation of a push button (open button).
In addition, since the locked / unlocked state can be recognized by visually recognizing the position of the operation piece provided on the indoor side of the inner summon bowl, the effect of preventing locking is enhanced.

以上のように、本発明に係る框内蔵型施錠装置によれば、中間歯車の上下に噛合する上下一対のラック体がそれぞれ逆方向に見込み方向に進退し、これらラック体の一方に噛合する歯車が設けられた掛け具を、上下一対のラック体の室内側の押しボタン操作により操作する構成であることから、上下個別の押しボタンのワンタッチ操作により施解錠を行うことができるため、押しボタンによる施解錠動作を確実にかつ安定して行うことができるとともに操作性を向上することができ押しボタンを2段階に押し込んで施解錠をする構成のように押し込みストロークを大きくする必要がないことから、内召合せ框から室内側へ押しボタンが大きく突出することがないため、すっきりとした滑らかな外観にすることができ、施錠状態では係合部材が係合凹部に係合することから押しボタン(開ボタン)を押すことができないロック状態となるため防犯性が高くなり、解錠する際には、操作片を操作して係合部材を係合凹部から外した状態とした後に、押しボタン(開ボタン)のワンタッチ操作により解錠することができ、内召合せ框の室内側に設けた操作片の位置を視認して施解錠状態を認識することができるため、施錠忘れ防止効果が高くなるという顕著な効果を奏する。
As described above, according to the locking device with a built-in scissors according to the present invention, the pair of upper and lower rack bodies that mesh with the upper and lower sides of the intermediate gear advance and retract in the opposite direction in the opposite direction, and the gears mesh with one of these rack bodies. Is provided by operating the push buttons on the indoor side of the pair of upper and lower rack bodies, and can be locked and unlocked by one-touch operation of the individual upper and lower push buttons. the unlocking operation reliably and stably with can be carried out can improve operability, it is not necessary to increase the pushing stroke as in the configuration of the locking and unlocking push the push button in two steps , since no button pressed from the inner召合allowed stile to the indoor side projects largely, can be made into a smooth appearance and clean, the engagement member is in the locked state Since it is locked so that the push button (open button) cannot be pressed because it engages with the engaging recess, crime prevention is enhanced, and when unlocking, the operating piece is operated to engage the engaging member After being removed from the recess, it can be unlocked by one-touch operation of the push button (open button), and the position of the operation piece provided on the indoor side of the inner summon bowl is visually recognized to recognize the unlocked state. it is possible, a marked effect of locking forgetting prevention effect may turn high.

Further, the hanging tool 9 may be disposed on the lower side of the lower rack body 6 and the gear 9A may be engaged with the lower rack teeth of the lower rack body 6. In this case, the upper push button 7 The close button becomes a close button, and the lower push button 8 becomes an open button.

以上のような框内蔵型施錠装置Aの構成によれば、前後方向に直動可能に支持された上下一対のラック体5,6が左右方向支軸S1まわりに回転可能に支持された中間歯車4を介して逆方向に進退することから、一方のラック体の押しボタン(閉ボタン)を室外方向へ押すと、受け具10に係合するように掛け具9が回動して施錠状態となり、この施錠状態から他方のラック体の押しボタン(開ボタン)を室外方向へ押すと、受け具10との係合を解除するように掛け具9が回動して解錠状態となる。
よって、上下個別の押しボタン7,8のワンタッチ操作により施解錠を行うことができるため、押しボタン7,8による施解錠動作を確実にかつ安定して行うことができるとともに操作性を向上することができる。
According to the configuration of the locking device A with a built-in hook as described above, the intermediate gear in which the pair of upper and lower rack bodies 5 and 6 that are supported so as to be linearly movable in the front-rear direction are rotatably supported around the left-right support shaft S1. 4, when the push button (close button) of one rack body is pushed in the outdoor direction, the hook 9 is rotated to be engaged with the receiver 10 and is locked. When the push button (open button) of the other rack body is pushed in the outdoor direction from this locked state, the hanging tool 9 is rotated so as to be disengaged from the receiving tool 10 to be unlocked.
Therefore, since it is possible to perform locking / unlocking by one-touch operation of the upper and lower individual push buttons 7, 8, the locking / unlocking operation by the push buttons 7, 8 can be performed reliably and stably and the operability is improved. Can do.

また、特許文献1のように1個の押しボタンを2段階に押し込んで施解錠をする構成のように押し込みストロークを大きくする必要がないことから、内召合せ框25から室内側へ押しボタンが大きく突出することがないため、すっきりとした滑らかな外観にすることが容易である。
さらに、施錠状態では係合部材11が係合凹部6Bに係合することから開ボタンである押しボタンを押すことができないロック状態となるため防犯性が高くなる。
さらにまた、操作片13により係合部材11を圧縮コイルばね12の弾性付勢力に抗して移動させることができるため、解錠する際には、操作片13を操作して係合部材11を係合凹部6Bから外した状態とした後に、押しボタン(開ボタン)のワンタッチ操作により解錠することができる。
また、内召合せ框25の室内側に設けた操作片13の位置を視認して施解錠状態を認識することができるため、施錠忘れ防止効果が高くなる。
Moreover, since it is not necessary to enlarge a pushing stroke like the structure which pushes one push button into two steps like patent document 1, and does the locking / unlocking, there is a push button to the indoor side from the inner summon bowl 25. Since it does not protrude greatly, it is easy to achieve a clean and smooth appearance.
Furthermore, since the engaging member 11 engages with the engaging recess 6B in the locked state, the locked state in which the push button which is an open button cannot be pressed is provided, so that the crime prevention performance is enhanced.
