Description

本発明は、開口部装置に係り、特に換気小窓を備えた開口部装置に関する。   The present invention relates to an opening device, and more particularly to an opening device provided with a ventilation small window.

開口部装置としては、障子に換気小窓を設けたサッシが知られている（例えば特許第２５９３０５８号公報、特開昭６３−１６５０７１号公報参照）。この種の換気小窓は、例えば上桟、下桟及び左右の縦桟からなる小窓枠内の室外側の幅方向略中間部に召合せ部材を上下に掛け渡し、小窓枠内の召合せ部材で仕切られた一方の領域の室外側に固定ガラスを設け、小窓枠内の室内側に可動ガラスを横方向にスライド開閉自在に設けて構成されている。小窓枠内の召合せ部材で仕切られた他方の領域の開口周縁部に、閉鎖時の可動ガラスの室外面に室外側から当接する気密材が設けられている。また、下桟の長手方向略中間部の室外面には可動ガラスを閉鎖位置で施錠するための締り具が設けられている。   As an opening device, a sash having a ventilation window in a shoji is known (see, for example, Japanese Patent No. 2593058 and Japanese Patent Laid-Open No. 63-165071). This type of ventilating window has a summing member vertically hung on a substantially intermediate portion in the width direction outside the inside of a small window frame composed of an upper beam, a lower beam, and left and right vertical beams, for example. A fixed glass is provided on the outdoor side of one region partitioned by the matching member, and a movable glass is provided on the indoor side in the small window frame so as to be slidable in a lateral direction. An airtight member that comes into contact with the outdoor surface of the movable glass at the time of closing from the outdoor side is provided at the opening peripheral edge of the other region partitioned by the summing member in the small window frame. In addition, a fastener for locking the movable glass in the closed position is provided on the outdoor surface of the substantially intermediate portion in the longitudinal direction of the lower rail.

しかしながら、前記サッシにおける換気小窓においては、止水構造として閉鎖時の可動ガラスの室外面に気密材を当接させて気密性及び水密性を確保するように構成されているため、無風状態では気密材が可動ガラスの室外面に十分に当って隙間が無かったとしても、室外側から風圧を受けると、可動ガラスが室内側に移動して気密材の当たりが弱くなってしまい、もしもその際に可動ガラスの室外面と気密材の間に隙間が発生するとその隙間から雨水が浸入する可能性があった。   However, in the ventilation small window in the sash, since the airtight material is brought into contact with the outdoor surface of the movable glass when closed as a water-stopping structure to ensure airtightness and watertightness, Even if the airtight material hits the outdoor surface of the movable glass sufficiently and there is no gap, if the wind pressure is applied from the outdoor side, the movable glass will move to the indoor side and the contact of the airtight material will be weakened. In addition, if a gap is generated between the outdoor surface of the movable glass and the airtight material, rainwater may enter through the gap.

また、雨水が小窓枠の下桟におけるガラス溝内に浸入した場合、十分な排水孔が構造上設けられていないため、室内側にオーバーフローする可能性があった。一方、風圧により可動ガラスが室内側に移動しても気密材の当りが十分であるように気密材の当り（ラップ代）を大きくすると、可動ガラスの開閉時に気密材の摩擦抵抗が大きくなり、操作性が悪くなってしまう。また、可動ガラスを開閉する際に引手部に手を掛けると、可動ガラスを室外側に押す方向に力が働くため、気密材の摩擦抵抗が一層大きくなってしまい、開閉が重くなるという問題がある。   In addition, when rainwater enters the glass groove in the lower frame of the small window frame, there is a possibility that it overflows indoors because sufficient drainage holes are not provided in the structure. On the other hand, if the contact of the airtight material (lap allowance) is increased so that the contact of the airtight material is sufficient even if the movable glass moves to the indoor side due to wind pressure, the friction resistance of the airtight material increases when the movable glass is opened and closed, The operability will deteriorate. In addition, when the movable glass is opened and closed, if a hand is put on the handle part, a force acts in the direction of pushing the movable glass to the outside of the room, which causes a problem that the frictional resistance of the airtight material is further increased and the opening and closing becomes heavy. is there.

前記締り具２６は、図２〜図６に示すように、召合せ部材１０の室内面の上下方向略中間位置にネジ止めにより取付けられる、裏面が開放されたケース３３と、該ケース３３の一側部に上下方向にスライド自在に設けられた操作部である操作摘み３４と、ケース３３内に収容されて設けられ、操作摘み３４の上下方向の動きをストッパー２７の回動と室内外方向の進退移動とに変換する変換機構３５と、ケース３３の裏面にネジ３６で取付けられる裏蓋３７とから主に構成されている。裏蓋３７にはストッパー２７の回動軸２７ａが貫通する孔部３８と、鉤部２７ｂを上向きの待機位置に収容する収容凹部３９とが形成されている。   As shown in FIGS. 2 to 6, the fastener 26 is attached to a substantially intermediate position in the vertical direction on the indoor surface of the summing member 10 by screwing, and a case 33 having a back surface opened and one of the cases 33. An operation knob 34, which is an operation section provided on the side portion so as to be slidable in the vertical direction, and is provided in a case 33. The vertical movement of the operation knob 34 is controlled by the rotation of the stopper 27 and the indoor and outdoor directions. It is mainly composed of a conversion mechanism 35 that converts it into forward and backward movement and a back cover 37 that is attached to the back surface of the case 33 with screws 36. The back cover 37 is formed with a hole 38 through which the rotation shaft 27a of the stopper 27 passes, and an accommodation recess 39 for accommodating the flange 27b in an upward standby position.

前記変換機構３５は、操作摘み３４により上下方向にスライド操作されるスライダー４０と、前記ストッパー２７の回動軸２７ａに先端が嵌合されてピン４１で固定され、前記裏蓋３７の孔部３８に回動可能及び進退移動可能に支持された駆動軸４２とからなっている。駆動軸４２には該駆動軸４２を前後に進退操作するための軸状の第１腕部４２ａと、該駆動軸４２を回動操作するための二股の第２腕部４２ｂとが径方向に突設されている。第２腕部４２ｂは、第１腕部４２ａよりも駆動軸４２の周方向における半時計方向に４５度程度位置をずらして配置されていることが好ましい。スライダー４０には第１腕部４２ａを案内してストッパー２７を引込み位置（待機位置）から突出位置に突出させるための傾斜した案内溝４０ａと、ストッパー２７を突出位置において時計方向に９０度回動させるために前記第２腕部４２ｂの溝４２ｃ内に係合する突軸４０ｂ（図６参照）とが設けられている。   The conversion mechanism 35 includes a slider 40 that is slid up and down by an operation knob 34, and a distal end that is fitted to a rotation shaft 27 a of the stopper 27 and fixed by a pin 41, and a hole 38 of the back cover 37. And a drive shaft 42 supported so as to be pivotable and movable back and forth. The drive shaft 42 includes a shaft-shaped first arm portion 42a for moving the drive shaft 42 back and forth and a bifurcated second arm portion 42b for rotating the drive shaft 42 in the radial direction. Projected. It is preferable that the second arm portion 42b is disposed with a position shifted by about 45 degrees in the counterclockwise direction in the circumferential direction of the drive shaft 42 with respect to the first arm portion 42a. The slider 40 has an inclined guide groove 40a for guiding the first arm portion 42a to project the stopper 27 from the retracted position (standby position) to the projecting position, and the stopper 27 is rotated 90 degrees clockwise at the projecting position. In order to achieve this, a projecting shaft 40b (see FIG. 6) that engages in the groove 42c of the second arm portion 42b is provided.

図５の（ａ）は操作摘み３４が最下部にあってストッパー２７が待機位置（解錠位置）にあるときの図、（ｂ）は操作摘み３４を略中間位置まで上方に操作してストッパー２７を突出位置にしたときの図、（ｃ）は操作摘み３４を最上部直前まで上方に操作してストッパー２７を時計方向に９０度回動させて施錠位置にしたときの図、（ｄ）は操作摘み３４を更に最上部まで操作してストッパー２７自体を解錠方向に回動できないロック状態にしたときの図である。   5A is a view when the operation knob 34 is at the lowermost position and the stopper 27 is at the standby position (unlocked position), and FIG. 5B is a diagram showing the stopper by operating the operation knob 34 upward to a substantially intermediate position. (C) is a view when 27 is in the protruding position, and (c) is a view when the operation knob 34 is operated upward just before the uppermost position and the stopper 27 is rotated 90 degrees clockwise to the locked position. FIG. 6 is a view when the operation knob 34 is further operated to the uppermost position so that the stopper 27 itself cannot be rotated in the unlocking direction.

図６の（ａ），（ｂ）は図５の（ａ）に対応する締り具の側面図と正面図、（ｃ），（ｄ）は図５の（ｂ）に対応する締り具の側面図と正面図、（ｅ），（ｆ）は図５の（ｃ）に対応する締り具の側面図と正面図、（ｇ），（ｈ）は図５の（ｄ）に対応する締り具の側面図と正面図である。操作摘みを最上部に操作すると、図６の（ｈ）に示すように突軸４０ｂが第２腕部４２ｂの溝４２ｃから離脱して第２腕部４２ｂの先端に当接することによりロック状態となり、ストッパー２７を外部から不正に解錠方向に回動しようとしても回動することができず、防犯性の向上が図れる。すなわち、第２腕部４２ｂの先端と突軸４０ｂは、ストッパー２７が施錠位置にあるときにストッパー２７の解錠方向への回動を阻止する回動阻止機構５２を構成している。なお、ストッパー２７を施錠位置から解錠位置に戻すには操作摘み３４を最上部から最下部まで下方に操作すれば良い。   6A and 6B are a side view and a front view of a fastener corresponding to FIG. 5A, and FIGS. 6C and 6D are side views of the fastener corresponding to FIG. 5B. The figure and a front view, (e), (f) is a side view and a front view of a fastener corresponding to (c) of FIG. 5, and (g), (h) is a fastener corresponding to (d) of FIG. It is a side view and a front view. When the operation knob is operated to the uppermost position, as shown in FIG. 6 (h), the projecting shaft 40b is detached from the groove 42c of the second arm portion 42b and comes into contact with the tip of the second arm portion 42b. Even if the stopper 27 is illegally rotated from the outside in the unlocking direction, the stopper 27 cannot be rotated, and the crime prevention can be improved. That is, the tip of the second arm portion 42b and the protruding shaft 40b constitute a rotation preventing mechanism 52 that prevents the stopper 27 from rotating in the unlocking direction when the stopper 27 is in the locking position. In order to return the stopper 27 from the locked position to the unlocked position, the operation knob 34 may be operated downward from the top to the bottom.

以上の構成からなるサッシ１によれば、建物の開口に設けられる四方枠２と、該四方枠２内に設けられた障子３，４と、その少なくとも一方の障子３に設けられた換気小窓５とを備え、該換気小窓５は、上桟８ａ、中横桟（下桟）８ｂ及び左右の縦桟８ｃ、８ｄからなる小窓枠８と、該小窓枠８内の室内側の幅方向略中間部に上下に掛け渡された召合せ部材１０とを有し、小窓枠８内の召合せ部材１０で仕切られた一方の領域の室内側に固定ガラス１６を設け、小窓枠８内の室外側に可動ガラス１７をスライド開閉自在に設け、小窓枠８内の召合せ部材１０で仕切られた他方の領域の開口周縁部に、閉鎖時の可動ガラス１７の室内面に室内側から当接する気密材１８を設けているため、換気小窓５の止水性及び開閉操作性の向上が図れる。   According to the sash 1 having the above-described configuration, the four-sided frame 2 provided in the opening of the building, the shojis 3 and 4 provided in the four-sided frame 2, and the ventilation small window provided in at least one of the shojis 3. The ventilation small window 5 includes a small window frame 8 composed of an upper beam 8a, a middle horizontal beam (lower beam) 8b, and left and right vertical beams 8c and 8d, and an indoor side in the small window frame 8. And a summing member 10 hung up and down at a substantially middle portion in the width direction, and a fixed glass 16 is provided on the indoor side of one region partitioned by the summing member 10 in the small window frame 8. A movable glass 17 is provided on the outdoor side of the frame 8 so as to be slidable. The other side of the small window frame 8 partitioned by the summing member 10 has an opening at the peripheral edge of the movable glass 17 when closed. Since the airtight member 18 that abuts from the indoor side is provided, the water stoppage and the opening / closing operability of the ventilation small window 5 can be improved.

すなわち、小窓枠８内の室外側に可動ガラス１７を配置し、閉鎖時の可動ガラス１７の室内面に室内側から気密材１８を当接させているため、室外側から風圧を受けても気密材１８の当たりが弱くなることがなく、可動ガラス１７の室内面と気密材１８の間に隙間が発生しにくいため、その隙間から雨水が浸入し難い。また、風圧により可動ガラス１７が室内側の気密材１８に対する当りが増大するので、従来の換気小窓のように気密材の当り（ラップ代）を大きくする必要がなく、可動ガラス１７の開閉時に気密材の摩擦抵抗を軽減でき、開閉操作性の向上が図れる。   That is, since the movable glass 17 is disposed outside the small window frame 8 and the airtight material 18 is brought into contact with the indoor surface of the movable glass 17 when closed from the indoor side, even if it receives wind pressure from the outdoor side. Since the contact with the airtight material 18 does not weaken and a gap is hardly generated between the indoor surface of the movable glass 17 and the airtight material 18, it is difficult for rainwater to enter from the gap. Further, since the contact of the movable glass 17 with the airtight material 18 on the indoor side increases due to the wind pressure, it is not necessary to increase the contact of the airtight material (lap allowance) unlike the conventional ventilation small window, and when the movable glass 17 is opened and closed. The frictional resistance of the airtight material can be reduced and the opening / closing operability can be improved.

また、可動ガラス１７を開閉する際に引手部３１に手を掛けると、可動ガラス１７を室外方向へ押して気密材１８から離れる方向に力が働くため、気密材１８の摩擦抵抗が一層軽減され、開閉を軽くでき、開閉操作性の更なる向上が図れる。更に、前記換気小窓５の下桟である中横桟８ｃには固定ガラス１６及び可動ガラス１７を装着するガラス溝２０ａ，２０ｂがあり、該ガラス溝２０ａ，２０ｂの下端とガラスの下端との間には空間２１ａ，２１ｂがあり、この空間２１ａ，２１ｂから室外に連通する排水孔２２ａ，２２ｂが設けられているため、雨水がガラス溝２０ａ，２０ｂ内に浸入したとしても、その雨水をガラス溝２０ａ，２０ｂの空間２１ａ，２１ｂに十分溜めることができるだけでなく、排水孔２２ａ，２２ｂから室外に排水することができ、雨水が室内側にオーバーフローするのを防止できる。また、換気小窓５に生じた結露水をガラス溝２０ａ，２０ｂに受けて排水孔２２ａ，２２ｂから室外に排水することができる。   In addition, when the handle 31 is put in hand when the movable glass 17 is opened and closed, a force acts in a direction away from the airtight material 18 by pushing the movable glass 17 in the outdoor direction, so that the frictional resistance of the airtight material 18 is further reduced. The opening and closing can be lightened, and the opening and closing operability can be further improved. Further, the middle horizontal rail 8c, which is the lower rail of the ventilation small window 5, has glass grooves 20a and 20b for mounting the fixed glass 16 and the movable glass 17, and the lower end of the glass grooves 20a and 20b and the lower end of the glass are connected to each other. There are spaces 21a and 21b between them, and drain holes 22a and 22b communicating from the spaces 21a and 21b to the outside of the room are provided. Even if rainwater enters the glass grooves 20a and 20b, Not only can it be sufficiently stored in the spaces 21a and 21b of the grooves 20a and 20b, but the water can be drained from the drain holes 22a and 22b to the outside, and rain water can be prevented from overflowing to the indoor side. Moreover, the dew condensation water produced in the ventilation small window 5 can be received by the glass grooves 20a and 20b and drained from the drain holes 22a and 22b to the outside.

前記召合せ部材１０には可動ガラス１７を閉鎖位置で施錠する締り具２６が設けられ、該締り具２６は解錠状態で可動ガラス１７よりも室内側に引っ込み、施錠状態で可動ガラス１７の可動領域（閉鎖位置の可動障子の召合せ側端部）まで突出するストッパー２７を有しているため、防犯性の向上が図れる。また、ストッパー２７には回動により可動ガラス１７を室内側に引き寄せる第２カム部（カム部）２９とが設けられているため、可動ガラス１７を閉鎖時に十分に室内側の気密材１８に押し当てることができ、止水性の更なる向上が図れる。このように換気小窓５は比較的に構造が簡単であるため、安価に製造することが可能である。   The summing member 10 is provided with a fastener 26 for locking the movable glass 17 in the closed position. The fastener 26 is retracted to the indoor side of the movable glass 17 in the unlocked state, and the movable glass 17 is movable in the locked state. Since it has the stopper 27 which protrudes to the area | region (the summit side end part of the movable shoji of a closed position), the improvement of crime prevention can be aimed at. Further, since the stopper 27 is provided with a second cam portion (cam portion) 29 that draws the movable glass 17 to the indoor side by rotation, the movable glass 17 is sufficiently pushed against the airtight material 18 on the indoor side when closed. It can be applied, and the water stoppage can be further improved. Thus, the ventilation small window 5 is relatively simple in structure and can be manufactured at low cost.

また、締り具２６は、ケース３３と、該ケース３３の一側部に上下方向にスライド自在に設けられた操作摘み（操作部）３４と、ケース３３内に設けられ、操作摘み３４の上下方向の動きをストッパー２７の回動と室内外方向の進退移動とに変換する変換機構３５とを有しているため、操作摘み３４のスライド操作だけで容易に施解錠を行うことができ、操作性の向上が図れる。また、締り具２６は、ストッパー２７が施錠位置にあるときにストッパー２７の解錠方向への回動を阻止する回動阻止機構４１を備えているため、ストッパー２７を外部から不正に解錠方向に回動することができず、防犯性の向上が図れる。   The fastener 26 includes a case 33, an operation knob (operation unit) 34 provided on one side of the case 33 so as to be slidable in the vertical direction, and a vertical direction of the operation knob 34 provided in the case 33. Since the conversion mechanism 35 that converts the movement of the stopper 27 into the rotation of the stopper 27 and the forward / backward movement in the indoor / outdoor direction can be easily locked / unlocked by simply sliding the operation knob 34. Can be improved. Further, since the fastener 26 includes the rotation prevention mechanism 41 that prevents the stopper 27 from rotating in the unlocking direction when the stopper 27 is in the locking position, the stopper 27 is illegally unlocked from the outside. Therefore, the crime prevention property can be improved.

The fastener 26 is attached to a substantially intermediate position in the vertical direction of the indoor surface of the summing member 10 by screws, and operates the case 33 with the back surface opened, the rotation of the stopper 27, and the forward / backward movement in the indoor / outward direction. Accordingly, an operation knob (operation unit) 34 provided at a substantially central portion of the indoor front portion of the case 33 so as to be rotatable and slidable (movable forward and backward) in the indoor and outdoor directions, and a screw 36 attached to the back surface of the case 33. The back cover 37 is mainly composed. The back cover 37 is formed with a long hole 38a capable of accommodating the stopper 27 in the standby position.

前記操作摘み３４は室外方向へ開口された円筒部３４ａを有し、この円筒部３４ａ内にはストッパー２７のベース部４３が軸方向（室内外方向）にスライド自在に嵌合されている。円筒部３４ａの先端部には円筒部すなわち操作摘み３４がケース３３から抜けないように係止する一対の係止爪部３４ｂが直径方向に突設されている。ケース３３内には操作摘み３４の円筒部３４ａを回動自在及び軸方向にスライド自在に収容する円形開口部３３ａが形成され、この円形開口部３３ａの内周面には、操作摘み３４の動きを規制すべく係止爪部３４ｂを案内するためのガイド溝４４が形成されている。ガイド溝４４は、操作摘み３４の押し込みを許容する軸方向の第１溝４４ａと、押し込んでから時計方向の略９０度の回動を許容する周方向の第２溝４４ｂとからなっている。また、施錠位置でストッパーが解錠方向に回動しないように阻止する回動阻止機構として前記第２溝部４４ｂの先端には係止爪部３４ｂを室内方向に係止させる凹状の係止受部４４ｃが形成されている。   The operation knob 34 has a cylindrical portion 34a opened in the outdoor direction, and a base portion 43 of a stopper 27 is fitted in the cylindrical portion 34a so as to be slidable in the axial direction (indoor / outdoor direction). A pair of locking claw portions 34b that lock the cylindrical portion, that is, the operation knob 34 so that it does not come off from the case 33, protrude in the diametrical direction at the distal end portion of the cylindrical portion 34a. A circular opening 33a is formed in the case 33 to accommodate the cylindrical portion 34a of the operation knob 34 so as to be rotatable and slidable in the axial direction. The movement of the operation knob 34 is formed on the inner peripheral surface of the circular opening 33a. A guide groove 44 for guiding the locking claw 34b is formed. The guide groove 44 includes an axial first groove 44a that allows the operation knob 34 to be pushed in, and a circumferential second groove 44b that allows a clockwise rotation of approximately 90 degrees after being pushed. Further, as a rotation blocking mechanism for blocking the stopper from rotating in the unlocking direction at the locking position, a concave locking receiving portion that locks the locking claw portion 34b in the indoor direction at the tip of the second groove 44b. 44c is formed.

前記ベース部４３は、操作摘み３４の円筒部３４ａ内にスライド自在に嵌合される円筒部４３ａと、前記ストッパー２７の基端部を嵌合させてピン４１で固定する駆動軸部４３ｂとからなり、操作摘み３４の円筒部３４ａ内周面とベース部４３の円筒部４３ａ外周面には互いに係合して相対的回動を規制し、軸方向のスライドのみを許容する規制溝３４ｃと突条部４３ｃが形成されている。前記ベース部４３の駆動軸部４３ｂには該ベース部４３を室内方向へ付勢する第１付勢手段であるコイル状の第１バネ４５と、該第１バネ４５の一端が当接されるワッシャー４６と、裏板３７の内面に当接される気密板４７が嵌合装着されている。ワッシャー４６は裏蓋３７のエッジ部に当接されている。また、操作摘み３４の円筒部３４ａとベース部４３の円筒部４３ａとの間には操作摘み４３を室内方向に付勢する第２付勢手段であるコイル状の第２バネ４８が介設されている。この場合、第２バネ４８は第１バネ４５よりもバネ力が弱く形成されており、操作摘み３４を押し込んで施錠位置に回動してから手を離すと、操作摘み３４が第２バネ４８により室内方向に押し戻されて係止爪部３４ｂが係止受部４４ｃに嵌合するようになっている。   The base portion 43 includes a cylindrical portion 43a that is slidably fitted into the cylindrical portion 34a of the operation knob 34, and a drive shaft portion 43b that is fitted with a base end portion of the stopper 27 and fixed by a pin 41.
