Description

本発明は、既設の窓の室内側に設ける内窓に関する。   The present invention relates to an inner window provided on the indoor side of an existing window.

従来、既設の窓の室内側に設ける内窓が知られており、一例として、特許文献１に示すように、上枠、下枠及び左右の縦枠を四周枠組みした枠体に障子をスライド自在に嵌め込んだものであって、枠体を既設の窓の室内側の躯体見込面に固定するものがある。このような内窓は、既設の窓に後から追加して取り付けることができ、容易に断熱性や防音性を向上させることができる点が特徴である。   Conventionally, an inner window provided on the indoor side of an existing window is known. As an example, as shown in Patent Document 1, a shoji can be slid freely on a frame body in which an upper frame, a lower frame, and left and right vertical frames are framed. The frame is fixed to the housing expected surface on the indoor side of the existing window. Such an inner window is characterized in that it can be additionally attached to an existing window later and can easily improve heat insulation and soundproofing.

特開２００８−３０３６０９号公報JP 2008-303609 A

ところで、特に浴室の窓において、既設の窓の室内側の躯体見込面のうち、下枠側の面に、その上面に滞留した水を室内側へ戻すための排水勾配が設けられている場合がある。このような場合であっても、内窓の下枠は水平に設置しなければ障子の開閉に支障を来してしまう。そこで従来、図６に示すように、障子１０２を支持するレール１５１を有する下枠１０５と躯体見込面１１０の間に下枠１０５の長手方向に延びるスペーサ１０３を挿入し、勾配の緩急に応じてスペーサ１０３の室内外方向の位置を調整することで下枠１０５の取付角度を水平に設定していた（図６（ａ）は勾配が緩やかな場合、図６（ｂ）は勾配が急な場合）。しかしながら、下枠１０５と躯体見込面１１０の間の間隔は狭く、また挿入したスペーサ１０３は下枠１０５の下側に隠れてしまうので、スペーサ１０３を全長にわたって適正な位置に配置することは困難であった。   By the way, especially in bathroom windows, there is a case where a drainage gradient for returning water accumulated on the upper surface to the indoor side is provided on the surface on the lower frame side of the indoor housing expected surface of the existing window. is there. Even in such a case, unless the lower frame of the inner window is installed horizontally, the opening and closing of the shoji will be hindered. Therefore, conventionally, as shown in FIG. 6, a spacer 103 extending in the longitudinal direction of the lower frame 105 is inserted between the lower frame 105 having the rails 151 for supporting the shoji 102 and the frame expectation surface 110, and according to the steepness of gradient The mounting angle of the lower frame 105 was set to be horizontal by adjusting the position of the spacer 103 in the indoor / outdoor direction (FIG. 6A shows a case where the gradient is gentle, and FIG. 6B shows a case where the gradient is steep. ). However, since the space between the lower frame 105 and the housing expected surface 110 is narrow, and the inserted spacer 103 is hidden under the lower frame 105, it is difficult to arrange the spacer 103 at an appropriate position over the entire length. there were.

It is characterized by that.

本発明のうち請求項１の発明によれば、下枠を躯体見込面に取り付けるにあたって、二つのスペーサが躯体見込面に当接する。そして、各スペーサの剥離部を適宜剥離することで、躯体見込面が傾斜している場合であっても下枠を水平に取り付けることができる。スペーサは係合部を取付部に係合させて予め下枠に取り付けてあるので、室内外方向の位置調整を行う必要がなく、施工が容易である。また、突起部が下枠の下面に当接することで、ガタのない部分で確実に荷重を受けられる。 According to the invention of claim 1 of the present invention, when attaching the lower frame to the building frame expected surface, two spacer abuts the precursor expected surface. And by peeling off the peeling part of each spacer suitably, even if it is a case where the housing | casing expected surface is inclined, a lower frame can be attached horizontally. Since the spacer is previously attached to the lower frame by engaging the engaging portion with the attaching portion, it is not necessary to adjust the position in the indoor / outdoor direction, and the construction is easy. In addition, since the projecting portion comes into contact with the lower surface of the lower frame, the load can be reliably received at a portion where there is no backlash.

本発明のうち請求項２の発明によれば、下枠を躯体見込面に取り付けるにあたって、一つのスペーサと下枠の他の部位、又は二つのスペーサが躯体見込面に当接する。何れの場合においても、各スペーサの剥離部を適宜剥離することで、躯体見込面が傾斜している場合であっても下枠を水平に取り付けることができる。スペーサは係合部を取付部に係合させて予め下枠に取り付けてあるので、室内外方向の位置調整を行う必要がなく、施工が容易である。また、突起部が下枠の下面に当接することで、ガタのない部分で確実に荷重を受けられる。 According to invention of Claim 2 among this invention, in attaching a lower frame to a housing | casing prospecting surface, the other site | part of one spacer and a lower frame, or two spacers contact | abut to a housing | casing prospecting surface. In any case, the lower frame can be attached horizontally by peeling off the peeling portions of the spacers as appropriate, even when the housing expected surface is inclined. Since the spacer is previously attached to the lower frame by engaging the engaging portion with the attaching portion, it is not necessary to adjust the position in the indoor / outdoor direction, and the construction is easy. In addition, since the projecting portion comes into contact with the lower surface of the lower frame, the load can be reliably received at a portion where there is no backlash.

以下、本発明の実施の形態を図面に基づいて説明する。この内窓の第一実施形態は、浴室の窓Ｗの室内側に設けるものである。図３に示すように、窓Ｗは躯体開口部の室外側寄りに取り付けてあって、窓Ｗの室内側には躯体見込面が形成してあり、下側の躯体見込面１０は、滞留した水が浴室側へ戻るように、浴室側へ向けて下方に傾斜している。そして内窓は、枠体１と、二枚の障子２ｐ，２ｑとを備えており、躯体見込面に取り付けてある。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1st embodiment of this inner window is provided in the indoor side of the window W of a bathroom. As shown in FIG. 3, the window W is attached to the outside of the housing opening, and a housing expectation surface is formed on the indoor side of the window W, and the lower housing expectation surface 10 stays. The water is inclined downward toward the bathroom so that the water returns to the bathroom. And the inner window is provided with the frame 1 and the two shoji 2p, 2q, and is attached to the housing | casing prospective surface.

枠体１は、上枠４と、下枠５と、左右の縦枠６からなるものである。下枠５は、図１に示すように、上側部材５ａと下側部材５ｂとを上下に重ねて構成してあり、上側部材５ａは、略平板状で、上面には長手方向に延びる二本のレール５１ｐ，５１ｑを有している。なおこの上側部材５ａは、下側部材５ｂと組み合わせずに直接躯体見込面１０に固定して、単独で内窓の下枠として使用することもできる。一方、下側部材５ｂは、略平板状で、室外側端には一段高い階段状に形成された段部５２を有し、室内側端の下面には水平部５３を有する。なお、上側部材５ａと下側部材５ｂとは、両面テープにより接合してある。そして、各レール５１ｐ，５１ｑがそれぞれ障子２ｐ，２ｑをスライド自在に支持しており、二枚の障子２ｐ，２ｑは枠体１に引き違いに納めてある。   The frame 1 includes an upper frame 4, a lower frame 5, and left and right vertical frames 6. As shown in FIG. 1, the lower frame 5 is configured by vertically stacking an upper member 5 a and a lower member 5 b, and the upper member 5 a has a substantially flat plate shape and two upper surfaces extending in the longitudinal direction on the upper surface. Rails 51p and 51q. In addition, this upper member 5a can be directly fixed to the housing expected surface 10 without being combined with the lower member 5b, and can be used alone as a lower frame of the inner window. On the other hand, the lower member 5b has a substantially flat plate shape, and has a stepped portion 52 formed in a stepped shape at the outdoor side end and a horizontal portion 53 on the lower surface of the indoor side end. The upper member 5a and the lower member 5b are joined with a double-sided tape. The rails 51p and 51q respectively support the shojis 2p and 2q so as to be slidable, and the two shojis 2p and 2q are placed in the frame 1 in a sliding manner.

下枠５の下側部材５ｂの下面には、室内側のレール５１ｐの直下の位置にスペーサ３が取り付けてある。スペーサ３は、下枠５の長手方向の全長にわたって延びるものであり、図２に示すように、略平板状の基部３２と、基部３２上面の室内外方向中央に形成した略Ｔ字形の係合部３３と、基部３２上面の室内外方向両端に形成した突起部３４とを有し、さらに基部３２の下面には、略平板状で、室外側から室内側へ向けて厚くなっている（ｔ１＜ｔ２）二枚の剥離部３１ａ，３１ｂが積層して形成してある。このスペーサ３は、塩化ビニル製で、上記の各要素がすべて一体成形されているが、基部３２と上側の剥離部３１ａ同士、及び上側の剥離部３１ａと下側の剥離部３１ｂ同士は、室内外方向中央及び両端の一部分でのみ繋がっており、剥離部３１ａ，３１ｂは手作業で容易に剥離できる。そして、下側部材５ｂの下面には、下側に向けて開口し長手方向に延びる溝状の取付部５４が形成してあり、取付部５４の長手方向端部からスペーサ３の係合部３３を挿入して取り付けてある。こうしてスペーサ３を取り付けると、突起部３４の上面が下側部材５ｂの下面に当接する。これは、スペーサ３の係合部３３と下側部材５ｂの取付部５４との間には、挿入可能にするために若干のガタがあるため、ガタのない部分でより確実に荷重を受けられるようにするためのものである。したがって、取付部５４の位置はレール５１ｐの位置よりやや室外側にずれており、スペーサ３を取り付けたときに、突起部３４がレール５１ｐの直下に位置するようなっている。 A spacer 3 is attached to the lower surface of the lower member 5b of the lower frame 5 at a position directly below the rail 51p on the indoor side. The spacer 3 extends over the entire length of the lower frame 5 in the longitudinal direction. As shown in FIG. 2, the spacer 3 has a substantially flat base 32 and a substantially T-shaped engagement formed in the center of the upper surface of the base 32 in the indoor / outdoor direction. Part 33 and protrusions 34 formed at both ends of the base 32 on the upper and lower sides of the base 32, and the bottom of the base 32 is substantially flat and thicker from the outdoor side toward the indoor side (t 1 <t 2 ) Two stripped portions 31a and 31b are stacked. The spacer 3 is made of vinyl chloride, and all the above-described elements are integrally formed. However, the base 32 and the upper peeling portions 31a, and the upper peeling portion 31a and the lower peeling portions 31b are indoors. It is connected only at the center in the outer direction and at both ends, and the peeling portions 31a and 31b can be easily peeled off manually. A groove-shaped attachment portion 54 that opens downward and extends in the longitudinal direction is formed on the lower surface of the lower member 5 b, and the engagement portion 33 of the spacer 3 extends from the longitudinal end portion of the attachment portion 54. Is inserted and installed. When the spacer 3 is attached in this way, the upper surface of the protrusion 34 comes into contact with the lower surface of the lower member 5b. This is because there is some backlash between the engagement portion 33 of the spacer 3 and the attachment portion 54 of the lower member 5b so that insertion is possible. It is for doing so. Therefore, the position of the attachment portion 54 is slightly shifted to the outdoor side from the position of the rail 51p, and the protrusion 34 is positioned immediately below the rail 51p when the spacer 3 is attached.

また、下枠５の下側部材５ｂの下面の室外側のレール５１ｑの直下の位置には、補助スペーサ３ｑが取り付けてある。補助スペーサ３ｑは、下枠５の長手方向の全長にわたって延びるものであり、スペーサ３の剥離部をすべて剥離したものと同じ形状である。下側部材５ｂの下面には、取付部５４と同じ形状の補助取付部５４ｑが形成してあり、取付部５４と同様に、レール５１ｑの位置よりやや室外側にずれている。   Further, an auxiliary spacer 3q is attached to a position directly below the outdoor rail 51q on the lower surface of the lower member 5b of the lower frame 5. The auxiliary spacer 3q extends over the entire length of the lower frame 5 in the longitudinal direction, and has the same shape as that obtained by peeling off all the peeling portions of the spacer 3. An auxiliary mounting portion 54q having the same shape as the mounting portion 54 is formed on the lower surface of the lower member 5b, and is slightly shifted to the outdoor side from the position of the rail 51q, like the mounting portion 54.

さらに、下枠５の下側部材５ｂの段部５２の根元部分からは、接地部５５が下側に突出している。接地部５５の高さはスペーサ３の突起部３４の高さと略同じである。さらに、下側部材５ｂの室内側端に形成した水平部５３も、スペーサ３の突起部３４の高さと略同じだけ下方に突出している。   Furthermore, the grounding portion 55 protrudes downward from the base portion of the step portion 52 of the lower member 5 b of the lower frame 5. The height of the grounding portion 55 is substantially the same as the height of the protruding portion 34 of the spacer 3. Further, the horizontal portion 53 formed at the indoor side end of the lower member 5 b also protrudes downward substantially by the same height as the protrusion 34 of the spacer 3.

このように構成した内窓は、躯体見込面１０が傾斜していても、下枠５の取付角度を水平に設定できる。すなわち、躯体見込面１０の傾斜角度が大きい場合には、図４（ａ）に示すように、スペーサ３の剥離部３１ａ，３１ｂをそのままにする。このようにすると、接地部５５の高さに対してスペーサ３の高さは二枚の剥離部３１ａ，３１ｂの分だけ高くなり、下枠５は略水平になる。この際、剥離部３１ａ，３１ｂが室外側から室内側へ向けて厚くなっているので、下側の剥離部３１ｂの下面が傾斜した躯体見込面１０と略平行になり、全面で接地してより確実に荷重を受けることができる。また、躯体見込面１０の傾斜角度が小さい場合には、図４（ｂ）に示すように、スペーサ３の下側の剥離部３１ｂのみを剥離し、上側の剥離部３１ａはそのままにする。このようにすると、接地部５５の高さに対してスペーサ３の高さは一枚の剥離部３１ａの分だけ高くなり、下枠５は略水平になる。この際、剥離部３１ａが室外側から室内側へ向けて厚くなっているので、剥離部３１ａの下面が傾斜した躯体見込面１０と略平行になり、全面で接地してより確実に荷重を受けることができる。そして何れの場合においても、室内側端においては躯体見込面１０と水平部５３との間に隙間が生じるので、コーキング５６を充填して塞いである。なお、コーキング５６を充填する際には、予め躯体見込面１０と水平部５３との間に閉止部材５９を挿入して、コーキング５６が奥へ浸入するのを防ぐ。また、補助スペーサ３ｑは躯体見込面１０に当接せず浮いた状態となっているが、これは下枠５が障子２ｐ，２ｑの荷重によりたわんだ際に荷重を受け、それ以上のたわみを防ぐものである。なお、スペーサ３の高さは剥離部一枚の厚さの単位でしか変更できないから、厳密には下枠５が水平にならない場合もあるが、スペーサ３は塩化ビニル製で弾性を有するから、ある程度の高さの誤差は吸収できる。さらに、躯体見込面１０が水平な場合には、図４（ｃ）に示すように、スペーサ３の両方の剥離部をすべて剥離する。このようにすると、スペーサ３、補助スペーサ３ｑ、接地部５５及び水平部５３は、すべて略同じ高さとなり、下枠５は水平になる。そして水平部５３には両面テープを貼って躯体見込面１０に接着し、周囲をコーキング５６で密閉してある。さらに、何れの場合においても、上側部材５ａの室内外方向両端部と、下側部材５ｂとの間にもコーキング５６を充填し、上側部材５ａと下側部材５ｂとの間に水が浸入するのを防いでいる。そして、このようにスペーサ３を調整した内窓については、上側、下側及び左右側の躯体見込面にアンカー５８を固定し、上枠４、下枠５及び左右の縦枠６をそれぞれネジ止めして固定する。特に下枠５においては、図１に示すように、段部５２の上面にネジ孔５７を形成し、ネジを挿入してある。これは、段部５２の上面が階段形状の高い位置になるので、下枠５の上面や障子２ｐ，２ｑから伝わってきた水が達しにくく、ネジ孔５７からの漏水を防止できるからである。   The inner window configured in this way can set the mounting angle of the lower frame 5 horizontally even if the housing expected surface 10 is inclined. That is, when the inclination angle of the housing expected surface 10 is large, as shown in FIG. 4A, the peeling portions 31a and 31b of the spacer 3 are left as they are. If it does in this way, the height of the spacer 3 will become high with the height of the grounding part 55 by the part of the two peeling parts 31a and 31b, and the lower frame 5 will become substantially horizontal. At this time, since the peeling portions 31a and 31b are thicker from the outdoor side toward the indoor side, the lower surface of the lower peeling portion 31b is substantially parallel to the inclined housing expected surface 10 and is grounded over the entire surface. A load can be reliably received. When the tilt angle of the housing expected surface 10 is small, as shown in FIG. 4B, only the lower peeling portion 31b of the spacer 3 is peeled and the upper peeling portion 31a is left as it is. If it does in this way, the height of the spacer 3 will become high with the height of the grounding part 55 by the part of the one peeling part 31a, and the lower frame 5 will become substantially horizontal. At this time, since the peeling portion 31a is thicker from the outdoor side toward the indoor side, the lower surface of the peeling portion 31a is substantially parallel to the inclined housing expected surface 10, and is grounded on the entire surface to receive the load more reliably. be able to. In any case, since a gap is generated between the housing expected surface 10 and the horizontal portion 53 at the indoor side end, the caulking 56 is filled and closed. In addition, when filling the caulking 56, the closing member 59 is previously inserted between the housing expected surface 10 and the horizontal portion 53 to prevent the caulking 56 from entering deeply. Further, the auxiliary spacer 3q is in a floating state without coming into contact with the housing expected surface 10. This is because the lower frame 5 receives a load when the lower frame 5 is bent by the load of the shoji 2p and 2q, and the deflection is larger than that. It is something to prevent. In addition, since the height of the spacer 3 can be changed only in the unit of the thickness of one peeling portion, strictly speaking, the lower frame 5 may not be horizontal, but the spacer 3 is made of vinyl chloride and has elasticity. Some height errors can be absorbed. Furthermore, when the housing expected surface 10 is horizontal, all the peeling portions of the spacer 3 are peeled off as shown in FIG. If it does in this way, the spacer 3, the auxiliary spacer 3q, the grounding part 55, and the horizontal part 53 will all become substantially the same height, and the lower frame 5 will become horizontal. A double-sided tape is attached to the horizontal portion 53 and adhered to the housing expected surface 10, and the periphery is sealed with a caulking 56. Furthermore, in any case, the caulking 56 is filled between the both ends of the upper member 5a in the indoor / outdoor direction and the lower member 5b, and water enters between the upper member 5a and the lower member 5b. Is prevented. For the inner window with the spacer 3 adjusted in this way, the anchor 58 is fixed to the upper, lower, and left and right side housing expectation surfaces, and the upper frame 4, the lower frame 5, and the left and right vertical frames 6 are screwed respectively. And fix. In particular, in the lower frame 5, as shown in FIG. 1, screw holes 57 are formed in the upper surface of the stepped portion 52, and screws are inserted. This is because the upper surface of the stepped portion 52 has a high stepped shape, so that the water transmitted from the upper surface of the lower frame 5 and the shoji 2p and 2q is difficult to reach and water leakage from the screw hole 57 can be prevented.

このように、本発明の内窓によれば、スペーサの剥離部を適宜剥離することで、躯体見込面が傾斜している場合であっても下枠を水平に取り付けることができる。スペーサは予め下枠に取り付けてあるので、室内外方向に位置調整を行う必要がなく、施工が容易である。また、スペーサの突起部が障子を支持するレールの直下に位置しており、しかも下枠の全長にわたって延びているから、障子がどの位置にスライドしても、その荷重をスペーサが直接受けるので、下枠が変形することがない。さらに、躯体見込面が傾斜している場合において、スペーサの形状が下枠と見込面との間の隙間の形状に一致し、より確実に下枠を支持することができる。また、スペーサが弾性を有するので、障子をスライドさせた際の振動を吸収し、より静寂で円滑な開閉が可能になる。   Thus, according to the inner window of the present invention, the lower frame can be attached horizontally by peeling off the peeling portion of the spacer as appropriate, even when the housing expected surface is inclined. Since the spacer is attached to the lower frame in advance, it is not necessary to adjust the position in the indoor / outdoor direction, and the construction is easy. In addition, since the protrusion of the spacer is located directly below the rail that supports the shoji and extends over the entire length of the lower frame, the spacer receives the load directly regardless of where the shoji slides. The lower frame is not deformed. Furthermore, when the housing expected surface is inclined, the shape of the spacer matches the shape of the gap between the lower frame and the expected surface, and the lower frame can be supported more reliably. Further, since the spacer has elasticity, it absorbs vibrations when the shoji is slid and can be opened and closed more silently.

なお、本実施形態においては、スペーサの剥離部について、室外側厚さｔ１＝０．８ｍｍ、室内側厚さｔ２＝１．０ｍｍ、見込幅が１５ｍｍ以上としてある。両端の厚さの差は僅かであるが、複数枚積層することで差の合計は大きくなり、躯体見込面の傾斜が大きくなるほど剥離部の残存枚数も増えるので、スペーサの下面と躯体見込面が常に略平行になる。また、スペーサの室内外方向の位置は、その室内側端が、構造材の室内側端と略一致しており、荷重を構造材で受けることができるようにしてある。そして、本実施形態は一般的な軸組木造家屋の場合を示しており、構造材の見込幅は約１０５ｍｍであるが、この内窓をツーバイフォー構造の家屋に用いた場合、構造材の見込幅は約９０ｍｍである。その場合でも、スペーサの見込幅が１５ｍｍ以上あるので、スペーサの室外側端が構造材の直上に位置し、やはり荷重を構造材で受けることができる。このようにスペーサの見込幅を１５ｍｍ以上にすることで、軸組構造の場合とツーバイフォー構造の場合の何れにおいても、スペーサを構造材の直上に位置させることができ、これは浴室の下額縁が構造材と強固に連結されていない場合や、額縁自身の剛性が低い場合に特に有効である。 In this embodiment, the spacer peeling portion has an outdoor thickness t 1 = 0.8 mm, an indoor thickness t 2 = 1.0 mm, and an expected width of 15 mm or more. The difference in thickness at both ends is slight, but the total difference increases by stacking multiple sheets, and the greater the slope of the housing expected surface, the greater the remaining number of peeled parts, so the lower surface of the spacer and the housing expected surface Always parallel. Further, the position of the spacer in the indoor / outdoor direction is such that the indoor side end thereof substantially coincides with the indoor side end of the structural material so that the load can be received by the structural material. And this embodiment has shown the case of a general frame wooden house, and the expected width of a structural material is about 105 mm, but when this inner window is used for a two-by-four structure house, the expected width of the structural material Is about 90 mm. Even in that case, since the expected width of the spacer is 15 mm or more, the outdoor end of the spacer is located immediately above the structural material, and the load can be received by the structural material. Thus, by setting the expected width of the spacer to 15 mm or more, the spacer can be positioned immediately above the structural material in both the case of the shaft assembly structure and the case of the two-by-four structure. This is particularly effective when the frame is not firmly connected to the structural material or when the rigidity of the frame itself is low.

次に、本発明の第二実施形態について、図５に基づき説明する。ただし、第一実施形態と異なるのは下枠５の一部分のみであり、それ以外の部分については説明を省く。第二実施形態において、下枠５は上側部材５ａと下側部材５ｂとを上下に重ねて構成してあり、上側部材５ａは二本のレール５１ｐ，５１ｑを有し、二枚の障子２ｐ，２ｑを支持している。一方、下側部材５ｂは、略平板状で、室内側端に、下側に突出する略Ｌ字形状の接地部５５を有しており、室外側のレール５１ｑの直下にスペーサ３を取り付けてある。スペーサ３は二枚の剥離部３１ａ，３１ｂを有するが、剥離部３１ａ，３１ｂの厚さは室内外方向で一定である。そして、接地部５５の高さは剥離部３１ａ，３１ｂを含むスペーサ３の高さと略同じである。   Next, a second embodiment of the present invention will be described with reference to FIG. However, only the part of the lower frame 5 is different from the first embodiment, and the description of other parts is omitted. In the second embodiment, the lower frame 5 is configured by vertically stacking an upper member 5a and a lower member 5b. The upper member 5a includes two rails 51p and 51q, and two sheets of shoji 2p, 2q is supported. On the other hand, the lower member 5b has a substantially flat plate shape, and has a substantially L-shaped grounding portion 55 protruding downward at the indoor side end, and the spacer 3 is attached directly below the outdoor rail 51q. is there. The spacer 3 has two peeling portions 31a and 31b, and the thickness of the peeling portions 31a and 31b is constant in the indoor and outdoor directions. The height of the grounding portion 55 is substantially the same as the height of the spacer 3 including the peeling portions 31a and 31b.

このように構成した第二実施形態においては、躯体見込面１０が水平な場合には、図５（ａ）に示すように、スペーサ３の剥離部３１ａ，３１ｂをそのままにする。このようにすると、スペーサ３と接地部５５は同じ高さとなり、下枠５は水平になる。一方、躯体見込面１０が傾斜している場合には、図５（ｂ）に示すように、スペーサ３の剥離部をすべて剥離する。このようにすると、接地部５５の高さに対してスペーサ３の高さは二枚の剥離部の分だけ低くなり、下枠５は略水平になる。この際、剥離部を剥離したスペーサ３の下面は水平であり、傾斜した躯体見込面１０とは平行にならないが、スペーサ３は塩化ビニル製で弾性を有するから、ある程度の角度の誤差は吸収できる。なお、躯体見込面の傾斜の角度によっては、剥離部を一枚だけ剥離してもよい。   In the second embodiment configured as described above, when the housing expected surface 10 is horizontal, the peeling portions 31a and 31b of the spacer 3 are left as they are as shown in FIG. If it does in this way, the spacer 3 and the grounding part 55 will become the same height, and the lower frame 5 will become horizontal. On the other hand, when the housing expected surface 10 is inclined, all the peeling portions of the spacer 3 are peeled off as shown in FIG. If it does in this way, the height of the spacer 3 will become low by the part of two peeling parts with respect to the height of the grounding part 55, and the lower frame 5 will become substantially horizontal. At this time, the lower surface of the spacer 3 from which the peeling portion has been peeled is horizontal, and is not parallel to the inclined housing expected surface 10, but since the spacer 3 is made of vinyl chloride and has elasticity, a certain degree of angle error can be absorbed. . Depending on the angle of inclination of the housing expected surface, only one peeling portion may be peeled off.

本発明は、上記の実施形態に限定されない。スペーサの剥離部の積層枚数は、一枚でもよいし、二枚より多くてもよい。また、スペーサの基部と剥離部、及び剥離部同士は、一体成形ではなく接着により剥離可能に接合してあってもよい。さらに、スペーサは短尺のものを下枠の見付方向にわたって間隔を空けて複数配置するものであってもよい。またスペーサの素材は、弾性を有するものであれば塩化ビニル以外のものであってもよい。さらに、スペーサは下枠に接着して取り付けてもよい。また、補助スペーサは、予めスペーサとは別に製造すれば、剥離部がない分だけ材料を節約できる。一方、スペーサの剥離部をすべて剥離したものを補助スペーサとして使用すれば、スペーサと補助スペーサを一つの製造工程で製造できるので効率がよく、どちらでもよい。さらに、第一実施形態において補助スペーサを取り付けた位置にも替わりにスペーサを取り付けて、室内側と室外側の二つのスペーサのそれぞれの剥離部を適宜剥離して角度及び高さを調節するようにしてもよい。また、下枠が上側部材と下側部材とに分かれていることにより、上側部材を単独で使用する内窓と部材を共用することができるが、上側部材と下側部材とが一体成形されていてもよく、この場合、両者を接合する手間が省けるので施工がさらに容易になる。さらに、躯体に下地材がある場合には、アンカーを用いることなく、下枠を直接躯体にネジ止めしてもよい。   The present invention is not limited to the above embodiment. The number of the peeled portions of the spacers may be one or more than two. Moreover, the base part and peeling part of a spacer, and peeling parts may be joined so that peeling is possible by adhesion | attachment instead of integral molding. Furthermore, a plurality of short spacers may be arranged at intervals over the direction of finding the lower frame. The spacer material may be other than vinyl chloride as long as it has elasticity. Further, the spacer may be attached by being adhered to the lower frame. Further, if the auxiliary spacer is manufactured in advance separately from the spacer, the material can be saved as much as there is no peeling portion. On the other hand, if a spacer having all the peeling portions peeled off is used as an auxiliary spacer, the spacer and the auxiliary spacer can be manufactured in one manufacturing process, which is efficient, and either may be used. Further, in the first embodiment, instead of the position where the auxiliary spacer is attached, a spacer is attached, and the peeling portions of the two spacers on the indoor side and the outdoor side are appropriately peeled to adjust the angle and height. May be. Further, since the lower frame is divided into the upper member and the lower member, the inner window and the member that use the upper member alone can be shared, but the upper member and the lower member are integrally formed. In this case, it is possible to save the labor of joining the two, so that the construction is further facilitated. Furthermore, when a base has a base material, the lower frame may be screwed directly to the casing without using an anchor.
