In the present embodiment, as the panel 35, as shown in FIG. 3, a multi-layer glass in which spacers 35c and 35c are sandwiched between two glasses 35a and 35b is illustrated, but a single plate glass may be used. However, from the viewpoint of improving heat insulating properties, double-glazed glass is preferred.

下障子30の上框31の室内側には引手部36が備えられており、該引手部36に手を掛けて操作することで、後に詳述するように、下障子30をガイド溝40に沿って上下に移動させることができる。以下、下障子30を可動障子30という。   A handle portion 36 is provided on the indoor side of the upper collar 31 of the lower shoji 30. By operating the handle portion 36 with a hand, the lower shoji 30 is inserted into the guide groove 40 as described in detail later. It can be moved up and down along. Hereinafter, the lower shoji 30 is referred to as a movable shoji 30.

また、図1〜3に示すように、上框31(引手部36)は、閉鎖姿勢で室内側から見て固定障子20の下框22を覆う形態になっている。かかる形態とすることによって、意匠性が向上するとともに、水密性、断熱性、及び防犯性に優れた構造となる。すなわち、閉鎖姿勢で固定障子20と可動障子30との間を上框31(引手部36)によって覆われることで、水や熱の出入りを防いで水密性及び断熱性を向上させるとともに、バールなどを差し込み難くすることで防犯性を高められる。   As shown in FIGS. 1 to 3, the upper rod 31 (the pulling portion 36) is configured to cover the lower rod 22 of the fixed shoji 20 when viewed from the indoor side in a closed posture. By setting it as this form, while improving designability, it becomes a structure excellent in watertightness, heat insulation, and crime prevention. That is, by covering the space between the fixed shoddle 20 and the movable shoji 30 with the upper rod 31 (the handle portion 36) in the closed posture, water and heat can be prevented from entering and leaving to improve water tightness and heat insulation, and bar Crime prevention can be improved by making it difficult to insert.

さらに、可動障子30の下框32の室内側には引手片39が備えられており、該引手片39は、後に詳述するように、下枠12に設けられた被係合部50と係合する係合部39として機能する。係合部39は、被係合部50と係合できる形状であれば特に限定されず、下框32の長手方向に沿って連続的に延在するか、又は下框32の長手方向に沿って断続的に備えられている。   Furthermore, a handle piece 39 is provided on the indoor side of the lower arm 32 of the movable shoji 30, and the handle piece 39 is engaged with an engaged portion 50 provided on the lower frame 12, as will be described in detail later. It functions as a mating engaging portion 39. The engaging portion 39 is not particularly limited as long as it has a shape that can be engaged with the engaged portion 50. The engaging portion 39 extends continuously along the longitudinal direction of the lower collar 32, or extends along the longitudinal direction of the lower collar 32. Are provided intermittently.

さらに、可動障子30の左縦框33及び右縦框34のそれぞれの下端部には、図2に示すように、見付方向外側に突出して支持部材38、38が取り付けられている。支持部材38は、ガイド溝40と係合する支持部38aを有する。また、支持部38aには、環状溝38bが備えられており、環状溝38bには、縦枠13、14の上部それぞれに内設されたバランサー60に連なるとともにガイド溝40に沿って配設されたワイヤー61の一端が係止されている(図2参照)。従って、可動障子30はバランサー60、60によって吊られた状態にある。バランサー60には渦巻きバネが内設されており、可動障子30の質量と平衡を保ち、可動障子30を小さな力で上下移動させることを可能にするとともに、任意の高さで停止させることができる。   Further, as shown in FIG. 2, support members 38 and 38 are attached to the lower ends of the left vertical rod 33 and the right vertical rod 34 of the movable shoji 30 so as to protrude outward in the finding direction. The support member 38 has a support portion 38 a that engages with the guide groove 40. The support portion 38a is provided with an annular groove 38b. The annular groove 38b is connected to the balancer 60 provided in each of the upper portions of the vertical frames 13 and 14, and is disposed along the guide groove 40. One end of the wire 61 is locked (see FIG. 2). Accordingly, the movable shoji 30 is suspended by the balancers 60 and 60. The balancer 60 is provided with a spiral spring so that the mass of the movable shoji 30 is kept in balance and the movable shoji 30 can be moved up and down with a small force and can be stopped at any height. .

可動障子30は、閉鎖姿勢では、図3に示すように、枠体10内側の固定障子20の下方において固定障子20と同一面内に並置されている。このとき、見付方向外側に突出するようにして上框31に設けられたラッチ70(図(a)参照)が、右の縦枠14に設けられた凹部(被係合部)71(図(a)参照)に係合されており、可動障子30のガタツキが防止されている。なお、図では右縦枠14側のみ図示しているが、左縦枠13側も同様である。
In the closed posture, the movable shoji 30 is juxtaposed in the same plane as the fixed shoji 20 below the fixed shoji 20 inside the frame 10 as shown in FIG. In this case, find the direction so as to project outwardly latch 70 provided in the upper rail 31 (see FIG. 7 (a)), recess provided in the vertical frame 14 of the right (engaged portion) 71 ( 7 (a)), the movable shoji 30 is prevented from rattling. 7 shows only the right vertical frame 14 side, the same applies to the left vertical frame 13 side.

また、閉鎖姿勢で可動障子30と固定障子20とが同一面内に並置されていることから、気密性を確保する部材を同一面内に設けることができ、可動障子と固定障子とを見付方向にずらして配設していた従来の上げ下げ窓より、気密性を高めることができる。より具体的には、上げ下げ窓100では、閉鎖姿勢において、固定障子20と上枠11との間にパッキン81(図3参照)を介在させ、固定障子20と右縦枠14との間にパッキン84(図6では可動障子30と右縦枠との間のパッキン84が図示されているが、パッキン84は右縦枠14に沿って延在している。)を介在させ、固定障子20と左縦枠13との間にパッキン(図示していないが、パッキン84と同様。)を介在させ、固定障子20の下框22と可動障子30の上框31との間にパッキン82(図3参照)を介在させ、可動障子30と下枠12との間にパッキン83(図3参照)を介在させ、可動障子30と右縦枠14との間にパッキン84(図6参照)を介在させ、可動障子30と左縦枠13との間にパッキン(図示していないが、パッキン84と同様。)を介在させている。これらのパッキンは上枠11、下枠12、左縦枠13又は右縦枠14に沿って延在しており、略同一面内に配設されている。そのため、気密性を確保しやすくなっている。また、可動障子30と固定障子20とが同一面内に並置され、上記パッキンが略同一面内に配設されていることから、断熱性を向上させることもできる。   Moreover, since the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane in the closed posture, a member for ensuring airtightness can be provided in the same plane, and the movable shoji and the fixed shoji can be found. The airtightness can be improved compared to the conventional raising and lowering windows that have been shifted in the direction. More specifically, in the raising / lowering window 100, in the closed position, a packing 81 (see FIG. 3) is interposed between the fixed shoji 20 and the upper frame 11, and the packing is disposed between the fixed shoji 20 and the right vertical frame 14. 84 (the packing 84 between the movable shoji 30 and the right vertical frame is shown in FIG. 6, but the packing 84 extends along the right vertical frame 14). A packing (not shown but similar to the packing 84) is interposed between the left vertical frame 13 and the packing 82 (see FIG. 3) between the lower collar 22 of the fixed shodder 20 and the upper shim 31 of the movable shoji 30. 3), a packing 83 (see FIG. 3) is interposed between the movable screen 30 and the lower frame 12, and a packing 84 (see FIG. 6) is interposed between the movable screen 30 and the right vertical frame 14. , Packing between the movable shoji 30 and the left vertical frame 13 (not shown) Bur, it is interposed similarly.) The packing 84. These packings extend along the upper frame 11, the lower frame 12, the left vertical frame 13 or the right vertical frame 14, and are arranged in substantially the same plane. Therefore, it is easy to ensure airtightness. Moreover, since the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane and the packing is disposed in substantially the same plane, the heat insulating property can be improved.

さらに、可動障子30と固定障子20とが同一面内に並置されることによって、防犯性の向上を図ることもできる。従来の上げ下げ窓では、枠体内側の下部に備えられた障子の下框と下枠との間にバールなどを差し込むことで該障子を押し上げ、該障子の上部に取り付けられたクレセント錠が破壊されるということがあった。しかしながら、上げ下げ窓100では閉鎖姿勢で可動障子30と固定障子20とが同一面内に並置されることから、下枠12と下框32との間にバールを差し込んで可動障子30を押し上げるということが困難である。   Furthermore, the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane, so that the crime prevention can be improved. In the conventional raising / lowering window, the shovel is pushed up by inserting a bar or the like between the lower arm of the shoji provided at the lower part inside the frame and the lower frame, and the crescent lock attached to the upper part of the shoji is destroyed. There was that. However, in the raising / lowering window 100, the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane in a closed posture, so that the bar is inserted between the lower frame 12 and the lower rod 32 to push up the movable shoji 30. Is difficult.

次に、可動障子30の開閉操作について説明する。図3に示すように、右縦枠14に形成されたガイド溝40は、直線部41及び傾斜部42を備えている。直線部41は、固定障子20に対して見込み方向内側において、縦枠14の長手方向に延在している。傾斜部42は、直線部41の下枠12側端に連通するとともに固定障子20が備えられる側の下枠12側に向かって延在している。   Next, the opening / closing operation of the movable shoji 30 will be described. As shown in FIG. 3, the guide groove 40 formed in the right vertical frame 14 includes a straight portion 41 and an inclined portion 42. The straight portion 41 extends in the longitudinal direction of the vertical frame 14 on the inner side in the prospective direction with respect to the fixed shoji 20. The inclined portion 42 communicates with the lower frame 12 side end of the linear portion 41 and extends toward the lower frame 12 side where the fixed shoji 20 is provided.

傾斜部42の水平面に対する傾斜角θ(図3参照)は特に限定されるものではないが、25度以上45度以下の範囲であることが好ましい。傾斜角θが小さ過ぎる場合は、可動障子30を開ける際に要する力が大きくなる。   The inclination angle θ (see FIG. 3) of the inclined portion 42 with respect to the horizontal plane is not particularly limited, but is preferably in the range of 25 degrees to 45 degrees. When the inclination angle θ is too small, the force required to open the movable shoji 30 increases.

可動障子30を開ける際には、まず、可動障子30の上框31の室内側に備えられた引手部36に手を掛けて室内側に引くことで、上框31に設けられたラッチ70を縦枠13、14に設けられた凹部71から離脱させる。そして、図4に示すように、支持部38aを支点として、ラッチ70がガイド溝40と係合するまで可動障子30を室内側に傾ける。このとき、ラッチ70及び支持部38aがガイド溝40と係合しているため、あとは引手部36や下框32に備えられた引手片39などに手を掛けて可動障子30を引き上げることで、図5に示すように、可動障子30をガイド溝40に沿って上方向へ移動させることができる。また、ラッチ70がガイド溝40と係合していることによって、可動障子30を上下移動させる際に、可動障子30の上部のガタツキを防止することができる。   When opening the movable shoji 30, first, the handle 70 provided on the indoor side of the upper arm 31 of the movable shoji 30 is placed and pulled to the indoor side, so that the latch 70 provided on the upper arm 31 is released. It is made to detach | leave from the recessed part 71 provided in the vertical frames 13 and 14. FIG. Then, as shown in FIG. 4, the movable shoji 30 is tilted indoors until the latch 70 engages with the guide groove 40 with the support portion 38 a as a fulcrum. At this time, since the latch 70 and the support portion 38a are engaged with the guide groove 40, the movable shoji 30 is lifted by placing a hand on the handle portion 36 or the handle piece 39 provided on the lower rod 32. As shown in FIG. 5, the movable shoji 30 can be moved upward along the guide groove 40. Further, since the latch 70 is engaged with the guide groove 40, when the movable shoji 30 is moved up and down, rattling of the upper portion of the movable shoji 30 can be prevented.

可動障子30を閉める際には、まず、引手部36や引手片39などに手を掛けて、支持部38aがガイド溝40の下端に達するまで可動障子30を引き下げる。その後、支持部38aを支点として可動障子30の上部を見込み方向外側に押すことでラッチ70をガイド溝40から離脱させるとともに、ラッチ70を凹部71に係合させる。   When closing the movable shoji 30, first, a hand is placed on the pulling portion 36, the pulling piece 39, etc., and the movable shoji 30 is pulled down until the support portion 38 a reaches the lower end of the guide groove 40. Thereafter, the upper portion of the movable shoji 30 is pushed outward in the prospective direction with the support portion 38a as a fulcrum, so that the latch 70 is detached from the guide groove 40 and the latch 70 is engaged with the recess 71.

また、上げ下げ窓100は、パネル35の室外側の面を掃除する際などには、図4に示した姿勢から、ラッチ70をガイド溝40から離脱させ、支持部38a、38aを支点として可動障子30をさらに室内側に傾けることができる(図6参照)。可動障子30を室内側に傾けることによって、下框32に備えられた係合部39が、下枠12に備えられた被係合部50と係合し、可動障子30の傾いた姿勢を保持することができる。このとき、可動障子30は、図6に示したA点で係合部39を介して被係合部50(下枠12)に支えられるとともに、図6に示したB点で支持部38aを介してガイド溝40(縦枠14)に支えられている。このように可動障子30に働く重力の作用によって可動障子30の姿勢が保持されており、係合部39が被係合部50から簡単に離脱することはない。   Further, when cleaning the outdoor side surface of the panel 35, the raising / lowering window 100 allows the latch 70 to be detached from the guide groove 40 from the posture shown in FIG. 4, and the movable obstacle with the support portions 38a and 38a as fulcrums. 30 can be further tilted indoors (see FIG. 6). By tilting the movable shoji 30 toward the indoor side, the engaging portion 39 provided in the lower collar 32 engages with the engaged portion 50 provided in the lower frame 12 and maintains the tilted posture of the movable shoji 30. can do. At this time, the movable shoji 30 is supported by the engaged portion 50 (lower frame 12) via the engaging portion 39 at the point A shown in FIG. 6, and the support portion 38a is shown at the point B shown in FIG. Via the guide groove 40 (vertical frame 14). Thus, the posture of the movable obstacle 30 is maintained by the action of the gravity acting on the movable obstacle 30, and the engaging portion 39 does not easily disengage from the engaged portion 50.

従来の上げ下げ窓では、室内側に傾けた障子の姿勢を保持するために、アームスライダーなどを備えさせていたため、部品点数が増え、上げ下げ窓の製造費用が高くなるなどの問題があった。一方、上げ下げ窓100では下框32に備えられた係合部39と下枠12に備えられた被係合部50とを係合させることによって、可動障子30の傾いた姿勢を保持させることができる。係合部39は下框32と一体の物として形成することが可能であり、被係合部50は下枠12と一体の物として形成することが可能である。従って、上げ下げ窓100では、部品点数を増やすことなく、可動障子30の傾いた姿勢を保持することができる。   In the conventional raising / lowering window, since an arm slider or the like is provided in order to maintain the posture of the shoji tilted toward the indoor side, there are problems that the number of parts increases and the manufacturing cost of the raising / lowering window becomes high. On the other hand, in the raising / lowering window 100, the inclined posture of the movable shoji 30 can be maintained by engaging the engaging portion 39 provided on the lower collar 32 and the engaged portion 50 provided on the lower frame 12. it can. The engaging part 39 can be formed as an integral part of the lower collar 32, and the engaged part 50 can be formed as an integral part of the lower frame 12. Therefore, the raising / lowering window 100 can maintain the tilted posture of the movable shoji 30 without increasing the number of parts.

係合部39及び被係合部50は、下框32及び下枠12の長手方向に沿って連続的に備えられていても良く、断続的に備えられていても良い。ただし、生産性の観点から、係合部39及び被係合部50は、下框32及び下枠12の長手方向に沿って連続的に備えられることが好ましい。また、係合部39及び被係合部50の下框32及び下枠12の長手方向に沿った方向の長さは特に限定されないが、係合部39及び被係合部50を係合させている際に係合部39及び被係合部50に負荷される荷重を分散させるという観点からは、長い方が好ましい。   The engaging part 39 and the engaged part 50 may be provided continuously along the longitudinal direction of the lower collar 32 and the lower frame 12, or may be provided intermittently. However, from the viewpoint of productivity, the engaging portion 39 and the engaged portion 50 are preferably provided continuously along the longitudinal direction of the lower collar 32 and the lower frame 12. The lengths of the lower flange 32 and the lower frame 12 in the longitudinal direction of the engaging portion 39 and the engaged portion 50 are not particularly limited, but the engaging portion 39 and the engaged portion 50 are engaged. From the viewpoint of dispersing the load applied to the engaging portion 39 and the engaged portion 50 during the operation, the longer one is preferable.

これまでの本発明の説明では、上部に固定障子を備え、下部に可動障子を備える形態の上げ下げ窓を例示して説明してきたが、本発明はかかる形態に限定されない。下框に備えられた係合部及び下枠に備えられた被係合部を具備する、傾いた障子の姿勢を保持する手段は、障子を見込み方向に傾けさせることができる機構を備えたあらゆる開口部装置に適用可能である。   In the description of the present invention so far, the description has been given by exemplifying the raising / lowering window in which the fixed obstacle is provided in the upper part and the movable obstacle is provided in the lower part, but the present invention is not limited to such a form. The means for maintaining the posture of the tilted shoji that includes the engaging portion provided on the lower arm and the engaged portion provided on the lower frame includes any mechanism that can tilt the shoji in the expected direction. It can be applied to an opening device.

さらに、本発明の上げ下げ窓100には、図1及び7に示すように、上框31の室内側に施錠装置37、37が備えられている。施錠装置37、37について以下に説明する。   Further, as shown in FIGS. 1 and 7, the raising / lowering window 100 of the present invention is provided with locking devices 37, 37 on the indoor side of the upper collar 31. The locking devices 37 and 37 will be described below.

施錠装置37は、上框31の引手部36の室内側に備えられた取っ手37a、及び、取っ手37aと連通しており引手部36の内側に備えられた係合部37bを備えている。開錠姿勢では図(a)に示すように係合部37bが引手部36の内側に納められている。取っ手37aを見付方向外側にスライドさせると、図(b)に示すように、係合部37bが見付方向外側に突出し、右縦枠14に形成された穴72から右縦枠14に挿入されるとともに、受け部(被係合部)73と係合して、施錠される。また、施錠姿勢から取っ手37aを見付方向内側にスライドさせることで、係合部37bが穴72から離脱し、開錠される。図では右側の施錠装置37についてのみ図示しているが、左側の施錠装置37も同様である。
The locking device 37 includes a handle 37 a provided on the indoor side of the handle portion 36 of the upper collar 31, and an engaging portion 37 b that communicates with the handle 37 a and is provided inside the handle portion 36. The unlocking posture engaging portion 37b as shown in FIG. 7 (a) are housed inside of the pull tab portion 36. Sliding the handle 37a to locate outwardly, as shown in FIG. 7 (b), projecting engaging portion 37b is in finding outwardly, the right vertical frame 14 from a hole 72 formed in Migitatewaku 14 While being inserted, it is engaged with the receiving portion (engaged portion) 73 and locked. Further, by sliding the handle 37a from the locking position to the inside in the finding direction, the engaging portion 37b is detached from the hole 72 and unlocked. Although only the right side locking device 37 is illustrated in FIG. 7 , the same applies to the left side locking device 37.

施錠装置37、37は正面視においてパネル25、35と重なることがなく、意匠性に優れる。また、施錠装置37、37は室外側からは見えず、室外側から鍵の位置を確認し難いため、防犯性に優れるという効果も有する。   The locking devices 37 and 37 do not overlap with the panels 25 and 35 in a front view, and are excellent in design. Moreover, since the locking devices 37 and 37 cannot be seen from the outdoor side, and it is difficult to confirm the position of the key from the outdoor side, it has the effect of being excellent in crime prevention.
