Description

本発明は、内召合せ框内に収容された錠本体の掛け具を外召合せ框内の受け具に係合させて施錠する框内蔵型施錠装置及び該施錠装置を備えたサッシ窓に関するものである。   TECHNICAL FIELD The present invention relates to a lock device with a built-in lock that locks a hook of a lock body housed in an internal summit bag with a receiving device in an external summit bag, and a sash window provided with the lock device. It is.

引違い、片引き又は両引き(引分け)の引き形式のサッシ窓の内召合せ框内に収容された錠本体の掛け具を、操作部材により操作して内召合せ框の室外側面から出没させ、外召合せ框内の受け具に係合させて施錠する框内蔵型施錠装置として、内召合せ框の室内側の面に沿って上下方向にスライド移動する操作部材、並びに、操作部材の直線運動を回転運動に変換し、そのトルクを掛け具(鍵片)に伝達する、減速比の小さな第一歯車列及び減速比の大きな第二歯車列を本体内に備え、掛け具が内召合わせ框内から出没する段階においては、操作部材の操作力を減速比の小さな第一歯車列を介して掛け具に伝え、掛け具が受け具(鍵受け)に係合又は離脱する段階においては、操作部材の操作力を減速比の大きな第二歯車列を介して掛け具に伝えるように構成してなるものがある(特許文献1参照。)。   The lock body of the lock body housed in the sash window of the pull-type, single-drawing, or double-drawing (draw) type sash window is operated by the operating member, and appears from the outdoor side of the internal sushi bowl. As an internal lock type locking device that engages and locks the receiving device in the outer summoning bowl, an operation member that slides up and down along the indoor side surface of the inner summoning bowl, and an operating member The main body has a first gear train with a small reduction ratio and a second gear train with a large reduction ratio that convert linear motion into rotational motion and transmit the torque to the device (key piece). In the stage where it appears and disappears from within the mating rod, the operating force of the operating member is transmitted to the hanging tool via the first gear train having a small reduction ratio, and in the stage where the hanging tool engages or disengages from the receiving tool (key holder). The operating force of the operating member is applied to the hanging tool through the second gear train having a large reduction ratio. It is made be configured to obtain (see Patent Document 1.).

特開2006−118135号公報(図6−9)JP 2006-118135 A (FIG. 6-9)

特許文献1の框内蔵型施錠装置は、室内側の操作部材を下方へ移動させる操作により掛け具が下方へ移動して受け具に係合し、操作部材を上方へ移動させる操作により前記係合が解除される構成であるため、違和感のない自然なモーションにより施解錠の操作を行うことができるとともに、掛け具を内召合わせ框内から突出させる際には減速比の小さな第一歯車列により動力を伝達させて掛け具を迅速に突出させることができ、掛け具を係合片(係合部)に押し込む際には減速比の大きな第二歯車列により動力を伝達させて小さな操作力により操作することができるという特長がある。
しかし、操作部材を操作する操作力の伝達を減速比が大きく異なる第一歯車列と第二歯車列との間で切り替えて掛け具に伝達する構成であることから、このような歯車列の切り替え(歯車の乗り移り)動作がうまくいかない場合があるため、動作の確実性及び円滑性の観点からは改良の余地がある。
In the lock device with a built-in bag of Patent Document 1, the hook is moved downward by the operation of moving the indoor operation member downward to engage the receiver, and the engagement is performed by the operation of moving the operation member upward. Because it is configured to be released, the locking and unlocking operation can be performed with natural motion without a sense of incongruity, and the first gear train with a small reduction ratio is used when the hanging device protrudes from the inside summoning cage. The power can be transmitted and the hanging tool can be quickly projected. When the hanging tool is pushed into the engagement piece (engagement portion), the power is transmitted by the second gear train having a large reduction gear ratio and a small operating force. It has the feature that it can be operated.
However, since the transmission of the operating force for operating the operating member is switched between the first gear train and the second gear train, which have greatly different reduction ratios, and transmitted to the hanging tool, such gear train switching is performed. (Gear transfer) Since the operation may not be successful, there is room for improvement from the viewpoint of the reliability and smoothness of the operation.

また、ラックに小径歯車を噛合させ、該小径歯車と同軸の大径歯車を掛け具に設けた扇状小歯車に噛合させる第一歯車列による動力の伝達と、前記小歯車を扇状大歯車に噛合させる第ニ歯車列による動力の伝達とを切り替える構成であり、これら歯車列の配置上の制約から、掛け具の回動角度を大きくとることができず、該回動角度が例えば100°程度となるため、掛け具の回動角度を大きくとって該掛け具により受け具の係合片を室内側に十分に引き寄せ、よって室外側障子を室内側障子へ十分に引き寄せて、気密性、水密性及び防犯性を高めるという観点からも改良の余地がある。
さらに、掛け具に対して同心の扇状大歯車及び扇状小歯車を軸方向にずらして取り付ける必要があるとともに、ラックの幅方向側方に大径歯車を配置していることから、錠本体の幅方向の厚みが比較的大きくなり、召合せ框の幅が小さい障子に対しては使用することができないため、適用対象が限定されている。
さらにまた、障子が開いた状態でも操作部材を下方へ移動させることができるため、障子が開いた状態で操作部材を下方へ移動させて掛け具を内召合わせ框内から突出させた状態とする誤操作を行った際には、この状態で障子を閉じると掛け具等が破損する場合があるとともに、障子が完全に閉じていない場合に操作部材を下方へ移動させると掛け具と受け具とが衝突して破損する場合がある。
Further, a small gear is meshed with the rack, and the first gear train is engaged with the small gear provided coaxially with the small gear, and the small gear is meshed with the large gear. The transmission of power by the second gear train to be switched is switched, and due to restrictions on the arrangement of these gear trains, the rotation angle of the hanging tool cannot be increased, and the rotation angle is about 100 °, for example. Therefore, the angle of rotation of the hanging tool is increased, and the engaging piece of the receiving device is sufficiently drawn to the indoor side by the hanging tool, and the outdoor shoji is sufficiently drawn to the indoor shoji, thereby being airtight and watertight. There is also room for improvement from the viewpoint of improving crime prevention.
In addition, it is necessary to shift the fan-shaped cogwheel and fan-shaped cogwheel concentrically with respect to the hanging tool in the axial direction, and since the large-diameter gear is arranged on the lateral side of the rack, the width of the lock body Since the thickness of a direction becomes comparatively large and it cannot be used for the shoji with the small width of the summon bowl, the application object is limited.
Furthermore, since the operating member can be moved downward even when the shoji is opened, the operating member is moved downward with the shoji opened so that the hanging tool protrudes from the inside summoning cage. If the shoji is closed in this state when an incorrect operation is performed, the hanger or the like may be damaged, and if the shoji is not completely closed, moving the operating member downward will cause the hanger and the receiver to move. It may be damaged by collision.

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、室内側の操作部材を下方又は上方へ移動させる自然なモーションにより施解錠の操作を行うことができ、施解錠を確実かつ円滑に行うことができ、受け具の係合片を室内側に十分に引き寄せることができるように掛け具の回動角度を大きくとることができ、錠本体をスリムにすることにより適用対象を拡大することができるとともに、障子を閉じた状態においてのみ操作部材を下方へ移動可能として誤操作等による掛け具等の破損を防止することができる框内蔵型施錠装置及び該施錠装置を備えたサッシ窓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 operation of locking / unlocking can be performed by a natural motion that moves the operation member on the indoor side downward or upward, so that the locking / unlocking can be performed reliably and smoothly. The angle of rotation of the hook can be increased so that the engaging piece of the receiver can be sufficiently pulled to the indoor side, and the application object can be expanded by slimming the lock body Provided are a lock device with a built-in lock and a sash window provided with the lock device, which can prevent the breakage of a hanging tool or the like due to an erroneous operation by allowing the operation member to move downward only when the shoji is closed. In the point.

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を幅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用いられる、室内側障子の内召合せ框内に収容された錠本体の掛け具の円弧状係合板を、上下方向にスライドする操作部材により室内側から操作して前記内召合せ框の室外側面から出没させ、室外側障子の外召合せ框内の受け具の係合片に係合させて施錠する框内蔵型施錠装置であって、前記錠本体に、前記掛け具の円弧状係合板に対して、その回動支軸を挟んで反対側に形成された歯車部と、該歯車部に噛合するように回動支軸により支持された小径歯車と、該小径歯車と同心に一体となって回動する大径歯車と、該大径歯車に常時噛合する歯が室外側面に形成され、上下方向にスライド可能に支持されるとともに前記操作部材と連結された上下方向に延びるラックとを備えたものである。   In order to solve the above-mentioned problem, the lock device with a built-in bag according to the present invention is used for a pull-type sash window that opens and closes an opening by sliding a plurality of shojis arranged in a frame in the width direction. The arcuate engagement plate of the lock body of the lock body housed in the shoji shoji sash is operated from the indoor side by an operating member that slides in the vertical direction, and is projected and retracted from the outdoor side of the inner squirrel. A lock-incorporating locking device that locks by engaging with an engaging piece of a receiving member in an outer summoning bag of an outer shoji, wherein the lock body is attached to the arc-shaped engaging plate of the hook. A gear portion formed on the opposite side across the moving support shaft, a small diameter gear supported by the rotation support shaft so as to mesh with the gear portion, and a large size that rotates concentrically with the small diameter gear. A diameter gear and a tooth that always meshes with the large diameter gear are formed on the outdoor side surface, and the tooth is It is obtained by a rack extending vertically which is connected to the operating member while being Ido movably supported.

ここで、前記錠本体に、前記内召合せ框の室外側面から突出する先端部に前記外召合せ框に向かう方向に近づくに従って室内方向へ傾斜する斜面が形成された室内外方向に延びるトリガーと、該トリガーを室外方向へ付勢する弾性付勢手段と、前記ラックと噛合するように回動支軸により支持されたガイド用歯車とを備え、前記障子を閉じて前記先端部の斜面が前記外召合せ框により押され、前記トリガーが前記弾性付勢手段の付勢力に抗して室内方向へ移動した状態では、前記ガイド用歯車が回動可能となり、前記障子を閉じた状態から前記障子を開けて前記トリガーが前記付勢力により付勢されて室外方向へ移動した状態では、前記トリガーにより前記ガイド用歯車が係止され、該ガイド用歯車の前記ラックを下降させる方向への回動が規制されると好ましい。   Here, in the lock body, a trigger extending in the indoor / outdoor direction is formed with a slope inclined in the indoor direction as it approaches the direction toward the external summit bowl at the tip portion protruding from the outdoor side surface of the internal summit bowl. And an elastic biasing means for biasing the trigger in the outdoor direction, and a guide gear supported by a rotating support shaft so as to mesh with the rack, and the slope of the tip portion is closed by closing the shoji When the trigger is pushed by an external summon and the trigger moves in the indoor direction against the urging force of the elastic urging means, the guide gear can be rotated, and the sash is closed from the closed state. When the trigger is urged by the urging force and moved in the outdoor direction, the guide gear is locked by the trigger, and the guide gear is rotated in the direction of lowering the rack. Preferably is control.

本発明に係るサッシ窓は、前記課題解決のために、前記框内蔵型施錠装置を備えたものである。   A sash window according to the present invention includes the lock device with a built-in heel for the purpose of solving the problems.

本発明に係る框内蔵型施錠装置及び該施錠装置を備えたサッシ窓によれば、室内側障子の内召合せ框内に収容された錠本体に、掛け具の円弧状係合板に対して、その回動支軸を挟んで反対側に形成された歯車部と、該歯車部に噛合するように回動支軸により支持された小径歯車と、該小径歯車と同心に一体となって回動する大径歯車と、該大径歯車に常時噛合する歯が室外側面に形成され、上下方向にスライド可能に支持されるとともに前記操作部材と連結された上下方向に延びるラックとを備えたので、室内側の操作部材を下方へ移動させる操作により掛け具が回動し、その円弧状係合板が下方へ移動して受け具の係合片に係合し、操作部材を上方へ移動させる操作により掛け具が前記回動と逆方向へ回動して前記係合が解除される構成であるため、違和感のない自然なモーションにより施解錠の操作を行うことができる。   According to the sash built-in locking device and the sash window equipped with the locking device according to the present invention, the lock body housed in the summoning jar of the indoor shoji, with respect to the arcuate engagement plate of the hanging tool, A gear portion formed on the opposite side across the rotation support shaft, a small-diameter gear supported by the rotation support shaft to mesh with the gear portion, and the concentric rotation with the small-diameter gear A large-diameter gear, and teeth that are always meshed with the large-diameter gear are formed on the outdoor side surface, and are supported so as to be slidable in the vertical direction, and a rack extending in the vertical direction connected to the operation member. By the operation of moving the operation member on the indoor side downward, the hanging tool is rotated, the arcuate engagement plate is moved downward and engaged with the engagement piece of the receiver, and the operation member is moved upward. The hook is rotated in the opposite direction to the rotation and the engagement is released. Because, it is possible to perform the operation of the locking and unlocking by the natural motion with no discomfort.

その上、室内側の操作部材と一体に上下動するラックには大径歯車が噛合するとともに、該大径歯車と一体に回動する小径歯車には掛け具に形成した歯車部が噛合し、これらは常時噛合していることから、歯車列の切り替え(歯車の乗り移り)がないため、施解錠を確実かつ円滑に行うことができる。
その上さらに、操作部材を操作する操作力の伝達を減速比が大きく異なる第一歯車列と第二歯車列との間で切り替える構成ではなく、これらの歯車列の配置上の制約がないことから、掛け具の回動角度を比較的大きく、該回動角度を例えば140°程度にすることができるため、掛け具により受け具を室内側に十分に引き寄せて室外側障子を室内側障子へ十分に引き寄せることができ、よって気密性、水密性及び防犯性を高めることができる。
その上、室内側の操作部材と一体に上下動するラックにはその室外側に位置する大径歯車が噛合するとともに、該大径歯車と一体に回動する小径歯車には掛け具に形成した歯車部が噛合する構成であることから、掛け具に対して同心の扇状大歯車及び扇状小歯車を軸方向にずらして取り付ける必要がなく、さらにラックの幅方向側方に大径歯車を配置していないことから、錠本体の幅方向の厚みを比較的小さくスリムにすることができるため、適用対象を拡大することができる。
In addition, a large-diameter gear meshes with the rack that moves up and down integrally with the indoor operation member, and a gear portion formed on the hanging gear meshes with the small-diameter gear that rotates integrally with the large-diameter gear, Since these are always meshed, there is no gear train switching (gear transfer), so that locking and unlocking can be performed reliably and smoothly.
Furthermore, it is not a configuration in which the transmission of the operating force for operating the operating member is switched between the first gear train and the second gear train having greatly different reduction ratios, and there is no restriction on the arrangement of these gear trains. Since the rotation angle of the hanging tool is relatively large and the rotation angle can be set to about 140 °, for example, the receiving object is sufficiently drawn to the indoor side by the hanging tool, and the outdoor obstacle is sufficiently moved to the indoor obstacle. Therefore, airtightness, watertightness and crime prevention can be improved.
In addition, the rack that moves up and down integrally with the operation member on the indoor side meshes with the large-diameter gear located on the outside of the room, and the small-diameter gear that rotates integrally with the large-diameter gear is formed as a hook. Since the gear portion is engaged, it is not necessary to shift the concentric fan-shaped large gear and fan-shaped small gear to the hanging tool in the axial direction, and a large-diameter gear is arranged on the lateral side of the rack. Therefore, since the thickness of the lock body in the width direction can be made relatively small and slim, the application target can be expanded.

また、前記錠本体に、前記内召合せ框の室外側面から突出する先端部に前記外召合せ框に向かう方向に近づくに従って室内方向へ傾斜する斜面が形成された室内外方向に延びるトリガーと、該トリガーを室外方向へ付勢する弾性付勢手段と、前記ラックと噛合するように回動支軸により支持されたガイド用歯車とを備え、前記障子を閉じて前記先端部の斜面が前記外召合せ框により押され、前記トリガーが前記弾性付勢手段の付勢力に抗して室内方向へ移動した状態では、前記ガイド用歯車が回動可能となり、前記障子を閉じた状態から前記障子を開けて前記トリガーが前記付勢力により付勢されて室外方向へ移動した状態では、前記トリガーにより前記ガイド用歯車が係止され、該ガイド用歯車の前記ラックを下降させる方向への回動が規制されると、前記効果に加え、障子が開いた状態ではトリガーによりラックを下降させる方向へのガイド用歯車の回動が規制されるため、操作部材を下方へ移動させて掛け具を内召合せ框から室外側へ突出させることができない。
よって、障子を閉じた状態においてのみ操作部材を下方へ移動させて掛け具の円弧状係合板を受け具の係合片に係合させ、確実に施錠することができるとともに、障子が開いた状態で掛け具を内召合せ框から室外側へ突出させる誤操作等を行うことができないため、掛け具等の破損を防止することができる。
Further, a trigger extending in the indoor / outdoor direction in which an inclined surface that is inclined toward the indoor direction is formed on the front end portion of the lock body that protrudes from the outdoor side surface of the internal summit bowl toward the outer summon bowl, Elastic urging means for urging the trigger in the outdoor direction; and a guide gear supported by a rotation support shaft so as to mesh with the rack; and the slope of the tip is closed by closing the shoji In a state where the trigger is pushed by the summoning rod and the trigger moves in the indoor direction against the urging force of the elastic urging means, the guide gear can be rotated, and the shoji can be moved from the closed state. In a state where the trigger is urged by the urging force and moved in the outdoor direction, the guide gear is locked by the trigger, and the rotation of the guide gear in the direction of lowering the rack is regulated. In addition to the above effects, in the state where the shoji is opened, the rotation of the guide gear in the direction of lowering the rack is restricted by the trigger, so the operating member is moved downward to summon the hanging tool. It cannot be protruded from the bag to the outside of the room.
Therefore, only when the shoji is closed, the operating member can be moved downward to engage the arc-shaped engaging plate of the hanging tool with the engaging piece of the receiving tool, and the shoji can be locked securely. In this case, it is not possible to perform an erroneous operation or the like for projecting the hanging tool from the inner summon bowl to the outside of the room, so that breakage of the hanging tool or the like can be prevented.

図3〜図6に示すように、錠本体11のケース12A及びその蓋体12B内の後側(室内側ID)には、上下方向に延び、前側(室外側OD)の面に歯が形成されたラック13が位置しており、該ラック13には、その前側に位置する、左右方向の回動支軸S3により軸支されたガイド用平歯車15及び左右方向の回動支軸S1により軸支された大径平歯車14Aが噛合するとともに、その後側(室内側ID)の面に、ケース12Aの室内側立起片12Eが当接するため、ラック13は上下方向にスライド移動可能に支持される。
Next, the structure in the lock body 11 of the lock device 10 with a built-in bag accommodated in the internal summon basket 5 will be described.
As shown in FIGS. 3 to 6, the case 12 </ b> A of the lock body 11 and the rear side (indoor ID) in the lid 12 </ b> B extend in the vertical direction, and teeth are formed on the front side (outdoor OD) surface. The rack 13 is located by a guide spur gear 15 pivotally supported by a left and right rotation support shaft S3 and a left and right rotation support shaft S1. Since the large-diameter spur gear 14A supported by the shaft meshes with the rear side (indoor ID) surface, the indoor upright piece 12E of the case 12A abuts, so that the rack 13 is slidably supported in the vertical direction. Is done.

ガイド用平歯車15の下側には、前後方向(室内外方向、奥行き方向、見込み方向)に延びるトリガー16が、その被カイド凹部16A(図7(a)も参照。)内にケース12Aに突設されたガイド凸部12Cが入り、これらが摺動するため、前後方向に移動可能に支持されており、上側に突設されたばね受け部16Bの後面を、ケース12Aから切り起こして一体に形成された切り起こし片により後端が支持された弾性付勢手段である圧縮コイルばね17が前方へ付勢しており、図4に示す障子3,4(図1参照。)が開いた状態で、ばね受け部16Bの前面がケース12Aの前板の後面12Fに当て止めされる。
また、トリガー16の後部には、その上面に円弧状凹部16Cが形成され、その後端部上面には水平な係止面16Dが形成されており、ガイド用平歯車15の右側のボス部(図7(a)も参照。)には、その周面をカットした形状に形成された被係止面15Aが形成されている。すなわち、前記ボス部の横断面の外形は略D字状になっている。
Below the guide spur gear 15, a trigger 16 extending in the front-rear direction (indoor / outdoor direction, depth direction, prospective direction) is placed in the case 12 </ b> A within the guide recessed portion 16 </ b> A (see also FIG. 7A). Since the protruding guide protrusion 12C enters and slides, it is supported so as to be movable in the front-rear direction, and the rear surface of the spring receiving portion 16B protruding upward is cut and raised from the case 12A to be integrated. The compression coil spring 17, which is an elastic biasing means whose rear end is supported by the formed cut and raised pieces, is biased forward, and the shoji 3, 4 (see FIG. 1) shown in FIG. 4 is opened. Thus, the front surface of the spring receiving portion 16B is abutted against the rear surface 12F of the front plate of the case 12A.
Further, an arcuate recess 16C is formed on the upper surface of the rear portion of the trigger 16, and a horizontal locking surface 16D is formed on the upper surface of the rear end portion thereof. The right boss portion (see FIG. 7 (a) also includes a locked surface 15A formed in a shape obtained by cutting the peripheral surface. That is, the outer shape of the cross section of the boss portion is substantially D-shaped.

したがって、図4及び図8(a)に示す障子3,4(図1参照。)が開いた状態では、トリガー16は、圧縮コイルばね17により前方へ付勢されて、その前端部が内召合せ框5の室外側面5Bから室外側ODへ突出し、ばね受け部16Bの前面がケース12Aの前板の後面12Fに当て止めされた状態で静止しており、ガイド用平歯車15の被係止面15Aにトリガー16の係止面16Dが当接してガイド用平歯車15が係止され、該ガイド用平歯車15は、その左方から見た(図4及び図8(a)に向かって見た)時計回りの回動が規制されるため、ラック13を下方へ移動させることができない(以下において、「トリガー作動状態」という。)。   Therefore, in the state in which the shoji 3, 4 (see FIG. 1) shown in FIGS. 4 and 8A is opened, the trigger 16 is urged forward by the compression coil spring 17, and the front end portion thereof is internally called. Projecting from the outdoor side surface 5B of the mating rod 5 to the outdoor side OD, the front surface of the spring receiving portion 16B is stationary with the rear surface 12F of the front plate of the case 12A being stopped, and the guide spur gear 15 is locked. The locking surface 16D of the trigger 16 is brought into contact with the surface 15A and the guide spur gear 15 is locked. The guide spur gear 15 is viewed from the left side (toward FIGS. 4 and 8A). Since the clockwise rotation is restricted, the rack 13 cannot be moved downward (hereinafter referred to as “trigger operating state”).

これに対して、障子3,4を閉じると(図1の矢印A参照。)、トリガー16の前端部(内召合せ框5の室外側面5Bから室外方向へ突出する先端部)に形成されている右方(外召合せ框6に向かう方向)に近づくに従って後方(室内方向)へ傾斜する斜面16E(図6参照。)に、外召合せ框6が当接するため、トリガー16が後方へ移動し(例えば図5及び図8(b)の状態参照。)、ガイド用平歯車15の被係止面15Aにトリガー16の係止面16Dが当接しなくなり、ガイド用平歯車15の右側のボス部の下側にはトリガー16の円弧状凹部16Cが、前記ボス部に対向するように位置するため、ガイド用平歯車15の回動が規制されなくなる(以下において、「トリガー解除状態」という。)。   On the other hand, when the shoji 3 and 4 are closed (see arrow A in FIG. 1), the trigger 16 is formed at the front end portion (the front end portion protruding from the outdoor side surface 5B of the inner summoning bowl 5). As the outer summoning basket 6 comes into contact with the slope 16E (see FIG. 6) that inclines backward (in the room direction) as it approaches the right side (the direction toward the outer summoning bowl 6), the trigger 16 moves backward. However, the locking surface 16D of the trigger 16 does not come into contact with the locked surface 15A of the guide spur gear 15 so that the right boss of the guide spur gear 15 can be obtained. Since the arc-shaped concave portion 16C of the trigger 16 is positioned below the boss portion so as to face the boss portion, the rotation of the guide spur gear 15 is not restricted (hereinafter referred to as “trigger release state”). ).

図3〜図6に示すように、ラック13には操作部材7が連結される連結板20が固定されているため、前記トリガー解除状態で操作部材7を上下方向にスライド移動させることにより、ラック13は操作部材7とともに上下方向にスライド移動する。
このようなラック13と操作部材7とを連結板20により連結する構成によれば、連結板20の形状(大きさ)を変更することにより、様々な断面形状の内召合せ框5に対して、該内召合せ框に錠本体11を収容して使用することができる。
また、左右方向の回動支軸S1により、大径平歯車14Aの右側に、大径平歯車14Aと同軸に小径平歯車14Bも軸支されており、大径平歯車14A及び小径平歯車14Bは、図7(b)に示すように大径平歯車14Aの係合凸軸14Cが小径平歯車14Bの係合孔14Dに嵌合されるため、これらは一体となって回転する。
As shown in FIG. 3 to FIG. 6, since the connecting plate 20 to which the operation member 7 is connected is fixed to the rack 13, the operation member 7 is slid up and down in the trigger release state, so that the rack 13 13 slides up and down together with the operation member 7.
According to the configuration in which the rack 13 and the operation member 7 are connected by the connecting plate 20, by changing the shape (size) of the connecting plate 20, the inner sump 5 having various cross-sectional shapes can be obtained. The lock body 11 can be accommodated in the summoning bowl.
Further, a small-diameter spur gear 14B is also supported on the right side of the large-diameter spur gear 14A by the left-right rotation support shaft S1, coaxially with the large-diameter spur gear 14A, and the large-diameter spur gear 14A and the small-diameter spur gear 14B. As shown in FIG. 7B, the engaging convex shaft 14C of the large-diameter spur gear 14A is fitted into the engaging hole 14D of the small-diameter spur gear 14B, so that they rotate together.

この小径歯車14Bには、左右方向の回動支軸S2により軸支された掛け具21の円弧状係合板21Aと回動支軸S2を挟んで反対側に一体形成された歯車部21Bが噛合する。
したがって、前記トリガー解除状態で操作部材7を下方へスライドさせると(図4中の矢印B参照。)、連結部材20を介してラック13が下方へ移動し、大径平歯車14Aとともに小径平歯車14Bが回動するため、小径平歯車14Bに噛合する歯車部21Bとともに掛け具21は受け具22に係合する位置(図5参照。)まで回動する。
The small-diameter gear 14B meshes with an arcuate engagement plate 21A of a hanging tool 21 that is pivotally supported by a left and right rotation support shaft S2 and a gear portion 21B that is integrally formed on the opposite side across the rotation support shaft S2. To do.
Therefore, when the operation member 7 is slid downward in the trigger release state (see arrow B in FIG. 4), the rack 13 moves downward via the connecting member 20, and the small diameter spur gear together with the large diameter spur gear 14A. Since 14B rotates, the hanging tool 21 rotates to the position (refer FIG. 5) engaged with the receiving tool 22 with the gear part 21B meshing with the small diameter spur gear 14B.

また、前記トリガー解除状態で操作部材7を上方へスライドさせると(図5中の矢印C参照。)、連結部材20を介してラック13が上方へ移動し、上述の動作と逆方向に大径平歯車14、小径平歯車14B、歯車部21Bが回動するため、掛け具21は受け具22との係合が解除される位置(図4及び図6参照。)まで回動する。
なお、掛け具21の側面に突設されたばね掛け21C及び蓋体12Bの内面に突設されたばね掛け12Dに引張コイルばね32の端末32A,32Bが掛止されるため、引張コイルばね32の付勢力が、掛け具21を受け具22に係合させる施錠時の途中から施錠方向に作用し、前記係合を解除する解錠時の途中から解錠方向に作用するため、軽い操作で施解錠を確実に行うことができる。
Further, when the operation member 7 is slid upward in the trigger release state (see arrow C in FIG. 5), the rack 13 moves upward via the connecting member 20 and has a large diameter in the direction opposite to the above operation. Since the spur gear 14, the small diameter spur gear 14 </ b> B, and the gear portion 21 </ b> B are rotated, the hanging tool 21 is rotated to a position where the engagement with the receiving tool 22 is released (see FIGS. 4 and 6).
Since the ends 32A and 32B of the tension coil spring 32 are hooked on the spring hook 21C protruding from the side surface of the hanging tool 21 and the spring hook 12D protruding from the inner surface of the lid 12B, the tension coil spring 32 is attached. Since the force acts in the locking direction from the middle of locking when the hook 21 is engaged with the receiving tool 22 and acts in the unlocking direction from the middle of unlocking to release the engagement, the locking and unlocking can be performed with a light operation. Can be performed reliably.

さらに、ラック13の歯の右側の段部前面には、その上下に係合凹部13A,13Bが形成されており、一端末18Aがピン19Aにより当止され、そのコイル内にピン19Bが挿通されたキックばね18の円弧状に形成した他端末18Bが、弾性変形した状態でラック13の前記段部前面に当接している。
そして、ラック13の上下方向に移動するストロークの上端(図4及び図6参照。)でキックばね18の端末18Bがラック13の下係合凹部13Bに係合し、前記ストロークの下端(図5参照。)でキックばね18の端末18Bがラック13の上係合凹部13Aに係合するため、前記ストロークの上下端でクリック感が得られて操作性が向上するとともに、自重によるラック13の落下が防止される。
Further, on the front surface of the stepped portion on the right side of the teeth of the rack 13, engagement recesses 13A and 13B are formed at the upper and lower sides thereof, one end 18A is stopped by a pin 19A, and the pin 19B is inserted into the coil. The other end 18B formed in the arc shape of the kick spring 18 is in contact with the front surface of the step portion of the rack 13 in an elastically deformed state.
Then, the end 18B of the kick spring 18 engages with the lower engagement recess 13B of the rack 13 at the upper end (see FIGS. 4 and 6) of the stroke that moves in the vertical direction of the rack 13, and the lower end of the stroke (FIG. 5). ), The end 18B of the kick spring 18 is engaged with the upper engagement recess 13A of the rack 13, so that a click feeling is obtained at the upper and lower ends of the stroke, and the operability is improved and the rack 13 is dropped by its own weight. Is prevented.

以上のような歯車伝達機構において、ラック13及び該ラック13と噛合する大径平歯車14Aを合成樹脂製とし、小径平歯車14B及び該小径平歯車14Bと噛合する歯車部21Bが形成された掛け具21を鋼製とすることにより、負荷側に近くより大きなトルクが掛かる歯車列を金属製として摩耗を抑制するとともに、負荷側から遠い(入力側である操作部材7に近い)歯車列を合成樹脂製として操作音を低減させている。
このように、一体となって回動支軸S1まわりに回動する同心の大径平歯車14Aと小径平歯車14Bとの材質を異なるものとしているが、前述のような係合凸軸14Cを係合孔14Dに嵌合する凹凸嵌合による構造(図7(b)参照。)により、部品点数や加工工数を削減しながら、材質の異なる大径平歯車14Aと小径平歯車14Bとを容易かつ確実に一体化することができる。
In the gear transmission mechanism as described above, the rack 13 and the large-diameter spur gear 14A that meshes with the rack 13 are made of synthetic resin, and the small-diameter spur gear 14B and the gear portion 21B that meshes with the small-diameter spur gear 14B are formed. By making the tool 21 made of steel, the gear train close to the load side and applied with a larger torque is made of metal to suppress wear, and the gear train far from the load side (close to the operation member 7 on the input side) is synthesized. The operation sound is reduced as it is made of resin.
As described above, the concentric large-diameter spur gear 14A and the small-diameter spur gear 14B that rotate integrally around the rotation support shaft S1 are made of different materials. A structure with a concave-convex fitting that fits into the engagement hole 14D (see FIG. 7B) facilitates the large-diameter spur gear 14A and the small-diameter spur gear 14B of different materials while reducing the number of parts and the number of processing steps. And it can integrate reliably.

障子3,4(図1参照。)が開いた状態(トリガー作動状態)で、仮にトリガー16が室外側ODから悪戯等により押された場合において、操作部材7(連結板20,ラック13)が下降してしまったとすると、図8(c)に示すように、トリガー16の前後方向(室内外方向)の位置は、図8(a)に示すトリガー作動状態と図8(b)に示すトリガー解除状態との中間位置となっている。
この状態では、ラック13に係合しているガイド用平歯車15は、その回動がトリガー16により規制されないため、図8(c)の矢印Dのように操作部材7(連結板20,ラック13)を押し上げることにより、ガイド用平歯車15が図中矢印Eのように回動し、図8(a)に示すトリガー作動状態に容易に復帰する。
When the shoji 3 and 4 (refer to FIG. 1) are opened (trigger operation state) and the trigger 16 is pushed from the outdoor OD by mischief or the like, the operation member 7 (the connecting plate 20 and the rack 13) is If it has fallen, as shown in FIG.8 (c), the position of the trigger 16 in the front-back direction (indoor / outdoor direction) is the trigger operation state shown in FIG. 8 (a) and the trigger shown in FIG. 8 (b). It is an intermediate position from the released state.
In this state, since the rotation of the guide spur gear 15 engaged with the rack 13 is not restricted by the trigger 16, the operation member 7 (the coupling plate 20, the rack is indicated by an arrow D in FIG. 8C). 13) By pushing up, the guide spur gear 15 rotates as shown by an arrow E in the figure, and easily returns to the trigger operating state shown in FIG.

以上のような框内蔵型施錠装置10及び該施錠装置10を備えた引き違いサッシ1(サッシ窓)によれば、障子3,4を閉じて前記トリガー解除状態として行う、室内側IDの操作部材7を下方へ移動させる操作により掛け具21が回動し、その円弧状係合板21Aが下方へ移動して受け具22の係合片22Aに係合し、操作部材7を上方へ移動させる操作により掛け具21が前記回動と逆方向へ回動して前記係合が解除される構成であるため、違和感のない自然なモーションにより施解錠の操作を行うことができる。   According to the locking device 10 with a built-in bag and the sliding sash 1 (sash window) provided with the locking device 10, the indoor ID operation member that closes the shoji 3 and 4 and releases the trigger is performed. An operation of moving the operating member 7 upward by rotating the hook 21 by rotating the lever 7 and moving the arcuate engagement plate 21A downward to engage with the engaging piece 22A of the receiving member 22. Thus, the hook 21 is rotated in the opposite direction to the rotation and the engagement is released, so that the unlocking / unlocking operation can be performed with a natural motion without a sense of incongruity.

その上、室内側IDの操作部材7と一体に上下動するラック13には大径歯車14Aが噛合するとともに、該大径歯車14Aと一体に回動する小径歯車14Bには掛け具21に形成した歯車部21Bが噛合し、これらは常時噛合していることから、歯車列の切り替え(歯車の乗り移り)がないため、施解錠を確実かつ円滑に行うことができる。
その上さらに、操作部材7を操作する操作力の伝達を減速比が大きく異なる第一歯車列と第二歯車列との間で切り替える構成ではなく、これらの歯車列の配置上の制約がないことから、掛け具21の回動角度を比較的大きく、該回動角度を例えば140°程度にすることができるため、掛け具21により受け具22を室内側に十分に引き寄せて室外側障子4を室内側障子3へ十分に引き寄せることができ、よって気密性、水密性及び防犯性を高めることができる。
In addition, a large-diameter gear 14A meshes with the rack 13 that moves up and down integrally with the operating member 7 of the indoor side ID, and a small-diameter gear 14B that rotates integrally with the large-diameter gear 14A is formed on the hanging tool 21. Since the gear portion 21B meshes and these are always meshed, there is no gear train switching (gear transfer), so that locking and unlocking can be performed reliably and smoothly.
Furthermore, the transmission of the operating force for operating the operating member 7 is not configured to be switched between the first gear train and the second gear train having greatly different reduction ratios, and there is no restriction on the arrangement of these gear trains. Therefore, the rotation angle of the hanging tool 21 can be made relatively large and the rotation angle can be set to about 140 °, for example. It can be drawn to the indoor side shoji 3 sufficiently, so that airtightness, watertightness and crime prevention can be improved.

その上、室内側IDの操作部材7と一体に上下動するラック13にはその室外側ODに位置する大径歯車14Aが噛合するとともに、該大径歯車14Aと一体に回動する小径歯車14Bには掛け具21に形成した歯車部21Bが噛合する構成であることから、掛け具21に対して同心の扇状大歯車及び扇状小歯車を軸方向にずらして取り付ける必要がなく、さらにラック13の幅方向側方に大径歯車を配置していないことから、錠本体11の幅方向の厚みを比較的小さくスリムにすることができるため、適用対象を拡大することができる。   In addition, a large-diameter gear 14A positioned on the outdoor side OD meshes with the rack 13 that moves up and down integrally with the operation member 7 of the indoor ID, and a small-diameter gear 14B that rotates integrally with the large-diameter gear 14A. Since the gear portion 21B formed on the hanging tool 21 meshes with the hanging tool 21, it is not necessary to shift the concentric fan-shaped large gear and fan-shaped small gear in the axial direction with respect to the hanging tool 21, and the rack 13 Since the large-diameter gear is not disposed on the side in the width direction, the thickness of the lock body 11 in the width direction can be made relatively small and slim, and thus the application target can be expanded.

その上さらに、障子3,4が開いた状態(前記トリガー作動状態)ではトリガー16によりラック13を下降させる方向へのガイド用平歯車15の回動が規制されるため、操作部材7を下方へ移動させて掛け具21を内召合せ框5から室外側へ突出させることができない。
よって、障子3,4を閉じた状態(前記トリガー解除状態)においてのみ操作部材7を下方へ移動させて掛け具21の円弧状係合板21Aを受け具22の係合片22Aに係合させ、確実に施錠することができるとともに、障子3,4が開いた状態(前記トリガー作動状態)では掛け具21を内召合せ框5から室外側ODへ突出させる誤操作等を行うことができないため、掛け具21等の破損を防止することができる。
Furthermore, when the shoji 3 and 4 are opened (the trigger operating state), the trigger 16 restricts the rotation of the guide spur gear 15 in the direction in which the rack 13 is lowered, so that the operation member 7 is moved downward. It is not possible to move the hanger 21 from the inner summon basket 5 to the outdoor side.
Therefore, only when the shoji 3 and 4 are closed (the trigger release state), the operating member 7 is moved downward to engage the arcuate engagement plate 21A of the hanging tool 21 with the engaging piece 22A of the receiving tool 22, It can be locked securely, and in the state in which the shoji 3 and 4 are opened (the trigger operation state), it is impossible to perform an erroneous operation or the like for projecting the hanging tool 21 from the inner summon 5 to the outdoor OD. Breakage of the tool 21 and the like can be prevented.
