一方，左右枠５ａ及び上下枠５ｂは，上記サッシ枠２と浴室壁面３間の空隙を閉塞する奥行幅に等しく，上記コーナー枠４の長さと同長の奥行幅を有するとともに上記コーナー枠４の嵌合突片４３の位置，形状及び数に合せて，左右枠５ａにあって上下端部，上下枠にあって左右端部のコーナー枠４側の端部にそれぞれ開口し，下面を開放するように凹陥状に配置するとともに，それぞれ外壁１と浴室壁面３間の奥行方向に向けて中間突条５１を介して同一ピッチに配置した裏面の嵌合溝５３を備えたものとしてあり，上記額縁７を設置した本例にあっては，その浴室側端部に外側に張出突設し且つ張出方向両端に額縁７嵌合用の嵌合部を備えたフランジ５４を備えることにより断面Ｌ字状をなして，例えば押出成形によって一体に成形したＬ字板状の成形部品によるものとしてあり，このとき本例の左右枠５ａ及び上下枠５ｂは，上記嵌合溝５３間の中間突条５１にそれぞれタッピングホール乃至タッピング溝，本例にあってはタッピング溝５２を備えたものとしてある。   On the other hand, the left and right frames 5a and the upper and lower frames 5b are equal in depth to block the gap between the sash frame 2 and the bathroom wall surface 3, have the same depth as the corner frame 4, and the corner frame 4 According to the position, shape, and number of the fitting protrusions 43, the upper and lower ends of the left and right frames 5a are opened at the ends of the upper and lower frames, and the left and right ends of the corner frame 4 side, and the lower surface is opened. And is provided with fitting grooves 53 on the back surface arranged at the same pitch via intermediate protrusions 51 in the depth direction between the outer wall 1 and the bathroom wall surface 3, respectively. In the present example in which 7 is installed, an L-shaped cross section is provided by providing a flange 54 that protrudes outward at the bathroom side end and has fitting portions for fitting the frame 7 at both ends in the extending direction. Formed in one piece, for example by extrusion In this case, the left and right frames 5a and the upper and lower frames 5b are tapped holes or tapping grooves in the intermediate protrusion 51 between the fitting grooves 53, respectively. A tapping groove 52 is provided.

左右枠５ａ及び上下枠５ｂの嵌合溝５３は，上記嵌合突片４３を密に被嵌するように該嵌合突片４３の寸法に応じてその横幅を２ｃｍ程度，深さを３ｍｍ程度とし，また上記嵌合を蟻溝嵌合とするように該嵌合溝５３を，その両側面を肉厚方向底面に向けて拡開するように傾斜した蟻溝用の傾斜面を有して該嵌合溝５３を上記２ｃｍ程度の最大横幅の蟻溝形状に形成してあり，該嵌合溝５３は上記押出成形によって，フランジ５４を除く左右枠５ａ及び上下枠５ｂの裏面全長に亘って同一断面形状をなして配置するようにこれを形成してある。   The fitting grooves 53 of the left and right frames 5a and the upper and lower frames 5b have a lateral width of about 2 cm and a depth of about 3 mm according to the dimensions of the fitting projections 43 so that the fitting projections 43 are tightly fitted. In addition, the fitting groove 53 has an inclined surface for dovetails that is inclined so that both sides of the fitting groove 53 expand toward the bottom surface in the thickness direction so that the fitting is a dovetail fitting. The fitting groove 53 is formed in a dovetail shape having a maximum lateral width of about 2 cm, and the fitting groove 53 extends over the entire back surface of the left and right frames 5a and the upper and lower frames 5b except for the flange 54 by the extrusion molding. This is formed so as to have the same cross-sectional shape.

このとき嵌合溝５３を有する左右枠５ａと上下枠５ｂは，これを左右枠５ａ及び上下枠５ｂの４面に共通部材のＬ字状部材として用い，左右枠５ａにあってその上下端部を傾斜切断することによって，これを外壁１側で短寸化して縮小し，浴室壁面３側で長寸化して拡大するように上下を傾斜端部５６とした，端部傾斜の平面台形状とする一方，上下枠５ｂにあってその左右端部を直交切断して平面四隅を直角とした平面矩形の形状としてあり，押出成形による上記共通のＬ字状部材を加工時の切断角度を違えて左右枠及び上下枠としてある。   At this time, the left and right frames 5a and the upper and lower frames 5b having the fitting grooves 53 are used as L-shaped members as common members on the four surfaces of the left and right frames 5a and 5b. Is inclined and cut off at the outer wall 1 side, and the upper and lower sides are inclined end portions 56 so as to be enlarged and enlarged at the bathroom wall surface 3 side. On the other hand, in the upper and lower frames 5b, the left and right end portions thereof are orthogonally cut to form a plane rectangular shape with the four corners at right angles, and the above-mentioned common L-shaped member by extrusion molding has a different cutting angle at the time of processing. As left and right frames and upper and lower frames.

左右枠５ａにおける傾斜端部５６の傾斜角度は，これを上記上下枠又は下枠，本例にあっては上下枠５ｂを傾斜するに際してその傾斜角度に合せた傾斜角度として設定するようにしてあり，本例にあって該傾斜端部５６の傾斜角度は，これを上記と同様に２度程度の角度としてある。   The inclination angle of the inclined end portion 56 in the left and right frames 5a is set as an inclination angle that matches the inclination angle when the upper and lower frames or the lower frame, in this example, the upper and lower frames 5b are inclined. In this example, the inclination angle of the inclined end portion 56 is set to about 2 degrees as described above.

このように形成したコーナー枠４，左右枠５ａ及び上下枠５ｂを用いた窓接続枠Ａの形成は，四隅のコーナー枠４を介して，該コーナー枠４の基枠４１に対してＬ字状に起立配置した各嵌合突片４３を左右枠５ａ及び上下枠５ｂの各嵌合溝５３に嵌合するとともに更に起立端部４４を該嵌合溝５３に圧入することによってこれら左右枠５ａ及び上下枠５ｂを枠組みし，本例にあっては基枠４１のネジ透孔４２からその長手方向交互に左右枠５ａ及び上下枠５ｂの上記タッピング溝５２に対してタッピングネジ４８を螺入して該コーナー枠４と左右枠５ａ及び上下枠５ｂをネジ固定し，また左右枠５ａ及び上下枠５ｂの上記フランジ５４に，その嵌合凹部５５に幅方向両端の嵌合突部７１をスナップイン的に嵌着することによって，例えば端部を留切りした断面コ字状の額縁７を囲繞状に設置するようにしてこれを行えばよく，これによって左右枠５ａが垂直面をなし，上下枠５ｂが，上枠において浴室側を上向きに，下枠において浴室側を下向きにそれぞれ２度程度の傾斜角度に微傾斜し，更に水密材４７が左右枠５ａと上下枠５ｂに密接して四隅の水密性を奥行方向全長に確保した矩形筒状の窓接続枠Ａを得ることができる。   The window connecting frame A using the corner frame 4, the left and right frames 5a and the upper and lower frames 5b formed in this way is formed in an L shape with respect to the base frame 41 of the corner frame 4 via the corner frames 4 at the four corners. The fitting protrusions 43 erected on the right and left frames 5a and 5b and the upper and lower frames 5b are fitted into the fitting grooves 53, and the raised end portions 44 are press-fitted into the fitting grooves 53, whereby the left and right frames 5a and In this example, tapping screws 48 are screwed into the tapping grooves 52 of the left and right frames 5a and the upper and lower frames 5b from the screw through holes 42 of the base frame 41 alternately in the longitudinal direction. The corner frame 4, the left and right frames 5a and the upper and lower frames 5b are fixed with screws, and the fitting protrusions 71 at both ends in the width direction are snapped into the flanges 54 of the left and right frames 5a and 5b. For example, the end This may be done by placing the cut-out U-shaped frame 7 in a go-like shape, whereby the left and right frames 5a form a vertical surface, and the upper and lower frames 5b face the bathroom side upward in the upper frame. A rectangular tube shape in which the bathroom side is slightly inclined at an inclination angle of about 2 degrees in the lower frame, and the water-tight material 47 is in close contact with the left and right frames 5a and 5b to ensure the water-tightness of the four corners in the entire depth direction. Window connection frame A can be obtained.

このとき嵌合突片４３の両側面が蟻溝嵌合一方の傾斜面をなし，嵌合溝５３が，その両側面を同じく蟻溝嵌合他方の傾斜面をなすように断面形状を蟻溝形状としたことによって，上記嵌合突片４３の嵌合溝５３に対する嵌合を蟻溝嵌合とすることができ，嵌合突片４３の嵌合溝５３に対する嵌合を強固且つ確実にして矩形筒状体としての捩れや歪みを解消して剛性を向上することができ，またコーナー枠４の基枠４１にネジ透孔４２を備え，左右枠５ａ及び上下枠５ｂの中間突条５１にタッピング溝５２を備えた本例にあっては，基枠４１から左右枠５ａ及び上下枠５ｂに対して基枠４１長手方向交互にタッピングネジ４８を螺入することによって該コーナー枠４と左右枠５ａ及び上下枠５ｂがネジ固定されて，窓接続枠Ａとしての枠組み強度を高度化し，その矩形筒状体として高度な剛性を備えたものとすることができ，更にコーナー枠４の基枠４１に，上記エラストマー等の水密材４７を備えた本例にあっては，該枠組みによってその軟質舌片が左右枠５ａ及び上下枠５ｂの縁部に密着載置するように対接し，コーキングを施すことなく高度な水密性を確保することができる。また本例の窓接続枠Ａは，上記コーナー枠４を四隅に共通部材とする一方，左右枠５ａと上下枠５ｂを，その加工時の切断角度を変えるも，断面Ｌ字状にして同一の押出成形の成形部材を共通に使用するものとしたことによって，接続窓枠Ａの基本的部材を２種類とし，該２種類の部材によって上記上下枠又は下枠が微傾斜した窓接続枠Ａを形成することができ，部材数の減少によるコスト低下を図ることができるメリットがある。因みに額縁７を付するときもこれを断面コ字状としたことによって該額縁７も長さを変化するも同一の，例えば押出成形による成形部材を共通に使用することができる。   At this time, both side surfaces of the fitting protrusion 43 form a dovetail fitting one inclined surface, and the fitting groove 53 has a dovetail cross-sectional shape so that both side surfaces form the other dovetail fitting inclined surface. By adopting the shape, the fitting protrusion 43 can be fitted into the fitting groove 53 with a dovetail fitting, and the fitting protrusion 43 can be firmly and reliably fitted into the fitting groove 53. Rigidity can be improved by eliminating twisting and distortion as a rectangular cylindrical body, and screw through holes 42 are provided in the base frame 41 of the corner frame 4, and the intermediate protrusions 51 of the left and right frames 5 a and the upper and lower frames 5 b are provided. In the present example provided with the tapping groove 52, the corner frame 4 and the left and right frames are screwed into the left and right frames 5a and 5b from the base frame 41 alternately by tapping screws 48 in the longitudinal direction of the base frame 41. 5a and upper and lower frames 5b are fixed by screws, and the frame strength as the window connection frame A In the present example in which the rectangular cylindrical body is provided with high rigidity, and the base frame 41 of the corner frame 4 is provided with a watertight material 47 such as the elastomer, The frame allows the soft tongue pieces to come into close contact with the edges of the left and right frames 5a and the upper and lower frames 5b, thereby ensuring high water tightness without caulking. The window connection frame A of this example uses the corner frame 4 as a common member at the four corners, while the left and right frames 5a and the upper and lower frames 5b have the same L-shaped cross section although the cutting angle at the time of processing is changed. By using the extrusion molding member in common, there are two types of basic members of the connection window frame A, and the window connection frame A in which the upper and lower frames or the lower frame is slightly inclined by the two types of members. It can be formed, and there is an advantage that the cost can be reduced by reducing the number of members. Incidentally, when the frame 7 is attached, the same shape, for example, a molded member by extrusion molding can be used in common although the length of the frame 7 is changed by making it U-shaped in cross section.

このとき上記嵌合突片４３を嵌合溝５３に嵌合することによって左右枠５ａを垂直に，上下枠５ｂを微傾斜状態に枠組みし得るのは，コーナー枠４における嵌合突片４３の側面が外壁側で垂直，浴室側で傾斜，特に微傾斜した状態で基枠４１に突出配置される一方，左右枠５ａの上下端部が微傾斜端部をなすために，コーナー枠４を左右枠５ａの傾斜端部５６に設置すると，コーナー枠４の嵌合突片４３における傾斜側面４６が該左右枠５ａの傾斜端部５６における傾斜を吸収し，該傾斜端部５６に対して直交するように対接して，コーナー枠４が傾斜端部５６に沿って傾斜配置される結果，該傾斜配置したコーナー枠４に対して設置された上下枠５ｂがその傾斜角度に応じて，本例にあっては２度の角度をなして微傾斜状態に枠組みされることになるからである。   At this time, by fitting the fitting protrusions 43 into the fitting grooves 53, the left and right frames 5a can be vertically framed and the upper and lower frames 5b can be framed in a slightly inclined state. The corner frame 4 is left and right so that the upper and lower ends of the left and right frames 5a form a slightly inclined end while the side faces are vertically inclined on the outer wall side and inclined on the bathroom side, particularly slightly inclined. When installed on the inclined end portion 56 of the frame 5 a, the inclined side surface 46 of the fitting protrusion 43 of the corner frame 4 absorbs the inclination at the inclined end portion 56 of the left and right frame 5 a and is orthogonal to the inclined end portion 56. As a result of the corner frame 4 being inclined and arranged along the inclined end portion 56, the upper and lower frames 5b installed with respect to the inclined corner frame 4 are arranged in this example according to the inclination angle. In that case, it is framed in a slightly inclined state at an angle of 2 degrees This is because become door.

本例にあって上記上下枠５ｂの傾斜角度はこれを２度程度としたが，該上下枠又は下枠の傾斜は，一般に水平に対して１〜５度の微傾斜角度とするのがよく，１度を下回ると上下枠又は下枠の傾斜が小さく，上枠にあっては水切り性が損なわれて，これに水滴が付着して滴下する傾向が生じ，下枠にあっては水捌け性が損なわれて，上枠から滴下した水滴や浴室内で飛散した水滴がそのまま滞留する傾向が生じる。また５度を上回ると傾斜が大きく，上枠にあって特段の問題はないが，下枠にあってはものを載置し難くなる傾向が生じる一方，上記額縁７を設けた場合にはその取付ベースをなす上下枠５ｂのフランジ５４が傾斜して浴室壁面３に対接するため，額縁７の浴室側への突出幅が大きくなる傾向を生じる。水切り性，水捌け性を良好に確保し，ものの安定した載置を可能とし，また額縁７を設けた場合にその突出幅の拡大を避けるためには，３±１度の微傾斜角度とすることが好ましい。従って上下枠又は下枠５ｂの傾斜角度を定める左右枠５ａの傾斜端部５６はこの微傾斜角度によるものとするのがよく，またコーナー枠４の嵌合突片４３における傾斜側面４６の角度は，該左右枠５ａの傾斜端部５６の角度を吸収すればよいから，該左右枠５ａの傾斜端部５６の角度と同一又はそれ以上の任意角度とすることが可能であるが，上記のように同一角度又は傾斜端部角度吸収可能な略同一の角度とすれば足り，殊更に角度を大きくするには及ばない。   In this example, the inclination angle of the upper and lower frames 5b is about 2 degrees, but the inclination of the upper and lower frames or the lower frame is generally set to a slight inclination angle of 1 to 5 degrees with respect to the horizontal. , If the angle is less than 1 degree, the inclination of the upper and lower frames or the lower frame is small, the draining property is impaired in the upper frame, and there is a tendency for water droplets to adhere to the lower frame, and the water drainage in the lower frame. The water drops dripped from the upper frame and the water drops scattered in the bathroom tend to stay as they are. If it exceeds 5 degrees, the inclination is large and there is no particular problem with the upper frame. However, when the frame is provided on the lower frame, the frame 7 tends to be difficult to place. Since the flange 54 of the upper and lower frames 5b forming the mounting base is inclined and comes into contact with the bathroom wall surface 3, the protruding width of the frame 7 toward the bathroom side tends to increase. In order to ensure good drainage and drainage, enable stable placement of objects, and to prevent the projection width from widening when the frame 7 is provided, a slight inclination angle of 3 ± 1 degree should be used. Is preferred. Accordingly, the inclined end portions 56 of the left and right frames 5a that define the inclination angle of the upper and lower frames or the lower frame 5b are preferably based on this slight inclination angle, and the angle of the inclined side surface 46 of the fitting protrusion 43 of the corner frame 4 is Since it is sufficient to absorb the angle of the inclined end portion 56 of the left and right frame 5a, the angle can be set to an arbitrary angle equal to or greater than the angle of the inclined end portion 56 of the left and right frame 5a. It is sufficient to set the same angle or substantially the same angle that can absorb the inclined end portion angle, and it is not necessary to increase the angle.

It is an end cap that is used as a retrofit for another member so as to form the fitting recess 55 and not to prevent the corner frame 4 from becoming a common part.

図示した例は以上のとおりとしたが，コーナー枠の基枠にＬ字状に配置した嵌合突片を，Ｌ字状一方の左右枠用とＬ字状他方の上下枠用に区分し，前者を上記正面片側傾斜の形状とし，後者を正面矩形の形状としたものとし，同様に端部キャップを別部材としてコーナー枠の共通部品化を図ること，上下枠のうち下枠だけを傾斜配置し上枠を水平配置するように構成すること，この場合必要に応じて上枠と左右枠上端の枠組み用のコーナー枠として，コーナー枠の基枠にＬ字状に配置した嵌合突片を共に正面矩形の形状とした他のコーナー枠を使用すること，上記共通部品のコーナー枠に代えて，端部キャップをコーナー枠に一体に設置し，左右勝手に応じた２種類のコーナー枠を使用すること，嵌合溝に対する嵌合突片を蟻溝嵌合に代えて，嵌合溝を断面コ字状の溝として形成し，嵌合突片を該嵌合溝に合せた側面形状とすることによって，また嵌合突片と嵌合溝の一方に突条を，他方に溝条を配置することによってこれらによる嵌合によって枠組みをなし得るようにすること等を含めて，本発明の実施に当って，コーナー枠，その基枠，嵌合突片，左右枠，上下枠，その嵌合溝，嵌合突片片側傾斜側面及び左右枠上下端部の傾斜角度，必要に応じて用いる水密材，ネジ固定等の各具体的形状，構造，材質，これらの関係，これらに対する付加等は，上記発明の要旨に反しない限り様々な形態のものとすることができる。   Although the illustrated example is as described above, the fitting protrusions arranged in an L shape on the base frame of the corner frame are divided into one for the left and right frames of the L shape and the other for the upper and lower frames of the L shape, The former is inclined to the front one side and the latter is a front rectangle. Similarly, the corner cap is made into a common part with the end cap as a separate member, and only the lower frame of the upper and lower frames is inclined. The upper frame is configured so as to be horizontally arranged. In this case, a fitting protrusion arranged in an L shape on the base frame of the corner frame is used as a corner frame for the upper frame and the upper end of the left and right frames as necessary.
