Description

【０００１】
【発明の属する技術分野】
この発明は、断熱出入り口枠と断熱障子から成る出入口用断熱サッシに関するものである。
【０００２】
【従来の技術】
寒冷地用サッシの窓枠を、アルミニウム合金製の室内側枠部材と室外側枠部材、及び両枠部材間に結合する断熱性連結材から形成し、且つ障子枠の各框を、アルミニウム合金製の室内側框部材と室外側框部材、及び両框部材間に結合する断熱性連結材から形成するものも開発されている。
即ち、窓枠を構成する上枠と下枠、及び、左右縦枠の総てを断熱性連結材にて結合する断熱構造としている（例えば、特開平７−６２９４９号公報、特開平９−１１２１３２号公報）。
【０００３】
窓枠を構成する上枠と下枠、及び左右縦枠の総てを、断熱性連結材にて結合する断熱構造とすると、窓枠に外力が加わった際、外力は耐力の弱い断熱性連結材に集中し、連結材と室内側枠部材、又は室外側枠部材の結合を損なう問題点があった。また出入口用サッシの下枠は、上から踏みつけたり、移動体の車が通り抜けたりするので、損傷したり破損したりする問題点があった。
【０００４】
【発明が解決しようとする課題】
そこで、本出願人は上記問題点を解決するために研究開発し、先に特願平１０−４２２６３号を出願した。本発明はその改良発明に関するものであり、その課題とするところは、下枠を耐応力の大きい単一形状でありながら、断熱性を維持し、障子閉鎖時の気密性を向上すると共に排水性及び耐久性の向上と、施工の簡略化を図ることができる出入口用断熱サッシを提供することにある。
【０００５】
【課題を解決するための手段】
上記課題を達成するために、本発明は下記の手段を施したものである。
請求項１記載の出入口用断熱サッシは、出入り口枠１を構成する上枠２と左右縦枠３，３が、アルミニウム合金製の室内側枠部材と室外側枠部材、及び、両枠部材を結合する断熱性連結材１５を備えた断熱構造で、出入り口枠１を構成する下枠４はステンレス製で非断熱構造を成し、下枠４と縦枠３，３は断熱コーナーブロック８，８を介して固定し、下枠４の室外側には沓摺４ａを併設し、該沓摺４ａの両端部は左右縦枠３，３の室外側位置に延設すると共に、断熱コーナーブロック８，８の両端部を縦枠３，３の室外側面と沓摺４ａとの間まで延設させて延設部８ｈとしたことを特徴とする。
【０００６】
請求項２記載の出入口用断熱サッシは、請求項１の手段において、上記延設部８ｈの室外側端縁に沿って立上り部８ｄを形成し、前記延設部上の立上り部８ｄと縦枠３，３との間を掃出し部８ｍとしたことを特徴とする。
【０００７】
【発明の実施の形態】
本発明による出入口用断熱サッシの実施例の全体構造について、図２〜４に基づき説明する。なお、出入口用断熱サッシとは、玄関サッシ、勝手口サッシ、浴室出入口等に用いる断熱サッシを言い、出入り口枠とは、建物開口部の内部に取付ける内付け出入り口枠及び開口部より室外側に突き出るように取付ける半外付け出入り口枠等を指す。
図２に示すように、躯体開口部、本実施例では玄関相当部にその内周に沿って出入り口枠１を設ける。該出入り口枠１は上枠２、縦枠３，３及び下枠４とからなり、全体としてアルミニウム合金製である。上枠２は室内側上枠部材２ａと室外側上枠部材２ｂとからなる。
【０００８】
また、縦枠３は室内側縦枠部材３ａと室外側縦枠部材３ｂとからなる。これら室内側上枠部材２ａと室外側上枠部材２ｂとの間には、断熱性連結材１５を介挿し、また、室内側縦枠部材３ａと室外側縦枠部材３ｂとの間にも断熱性連結材１５を介挿し、それぞれ室内外の断熱を図っている。
【０００９】
しかし、下枠４は室内外の二部材からは構成していない。即ち、出入りする人の体重がかかる等で最も外力が作用する下枠４は、図３，４に示すように、単一物から成り、長尺の箱型を成し、その下側に付設する支持部４ｂ上に載置・固定してある。支持部４ｂは下枠４の補強と、埋設時の位置決め等を兼ねるものである。
下枠４の上面には内・外レール５ａ，５ｂ及び補助レール５ｃを形成する。後述するように、本実施例は下枠４を単一部材から形成していることで、耐応力を大きくし、しかも出入り口枠１全体としての断熱性の向上を図るものである。
出入り口枠１内には、内・外障子６，７を内レール５ａ及び外レール５ｂ（図３，４参照）に沿って開閉自在に配置する。内・外障子６，７はそれぞれ内障子框６ａ、外障子框７ａと該内・外障子框６ａ，７ａが支持する複層ガラス１３とからなる。
【００１０】
図３，４に示すように、下枠４の室内側は下枠４に形成したレール５の高さと略同一高さに室内床面２０を形成し、下枠４の室外側には沓摺４ａを取り付ける。沓摺４ａは、室外側床面と下枠４との間を塞ぐ、或いは、橋渡しする部材であり、アルミニウム合金製の押出形材或いは鋼板製で、その断面は、図３に示すような折曲板からなっている。
図３に示すように、沓摺４ａの室内側端縁（右端面）は、下枠４の上面に装着され、沓摺４ａの室外側（左端面）は室外側床面と略同一高さとなっている。
【００１１】
既に述べたように、下枠４の両端と縦枠３，３の下端部は断熱コーナーブロック８を介して連結する。該断熱コーナーブロック８は、断熱性・耐候性が高く且つ機体的特性が高い合成樹脂を用い、図１，５〜７に示すように、室内外方向（面外方向）に長い長尺物として形成する。
断熱コーナーブロック８の上面は平坦部８ｂとし、該平坦部８ｂには、内・外レール５ａ，５ｂの延長線上位置に隅丸部８ａ，８ａを設け、更に、外レール５ｂに隣接する補助レール５ｃの延長線上の位置に、気密用のモヘアを支持させる気密材支持部材８ｊを設ける。
【００１２】
また、断熱コーナーブロック８の一側面、即ち、下枠４端部を当接する下枠当接面８ｋから、他側面、即ち、縦枠３下端部を当接する縦枠当接面８ｌに連通して連結穴８ｃ，８ｃ・・を穿設する。また、断熱コーナーブロック８の室内側端部には、平面視Ｌ型の立上り片８ｉを一体に形成する。
【００１３】
断熱コーナーブロック８の室外側端部は、平坦部８ｂ部分とは直角に延設部８ｈを形成し、且つ該延設部８ｈの室外側縁に立上り部８ｄを形成し、更にこの上面を傾斜部８ｅとして形成する。また、この外面に沓摺４ａ端部を嵌合させるための凹部を形成して嵌合部８ｆとする。
なお、上記延設部８ｈの室内側面は、縦枠３の室外側面に当接させることになる。更に、上記立上り部８ｄ内に、沓摺４ａの長さ方向と平行のウインドウ状の空隙部８ｇを穿設する。
【００１４】
更に、図３，４に示すように、上枠２の断熱性連結材１５と、縦枠３，３の断熱性連結材１５の少なくとも一方の内周側に、断熱性連結材１５を隠蔽する目隠し材１６を取付ける。何れも断熱性に優れた合成樹脂より形成するものである。また縦枠３の下部で外障子７の当接部には、風止板９を取付けて気密性に加えて遮水性の向上を図っている。
【００１５】
更に、図４に示すように、内障子框６ａと外障子框７ａの室外側にはそれぞれ把手１７を設ける。各把手１７，１７は把持部１７ａが上下方向の丸棒からなり、該各把持部１７ａを上下で支持する腕杆１７ｂ，１７ｂは一部で折れ曲げた形状となっている。
出入り口枠１を構成する上枠２と縦枠３との組み付け手段は従来のものと変わらない。下枠４と断熱コーナーブロック８との連結は、前記左右の断熱コーナーブロック８の連結穴８ｃ，８ｃにボルト（図外）を挿通して締め付ける。この締め付け手段は本出願人の先願技術（特願平１０ー４２２６３号）と同じである。
【００１６】
上記実施例の出入口用断熱サッシは、上枠２と縦枠３，３が、アルミニウム合金製の枠部材と、断熱性連結材から成る断熱構造であっても、下枠４が一体の非断熱構造を成すので出入り口枠１の耐久力が著しく向上する。また下枠４が一体構造であっても、断熱コーナーブロック８を介して断熱縦枠と固定するので、断熱効果を維持することができる。
また、障子閉鎖時の気密を向上すると共に、耐久性の向上と施工の簡略化を図ることができ、更に、沓摺４ａにかかる外力による変形を、断熱コーナーブロック８に吸収させることができて、出入り口枠１全体への変形力の影響を少なくしている。
【００１７】
特に、合成樹脂の弾性は金属弾性より大であるから、最も大きな外力がかかる沓摺４ａの変形を断熱コーナーブロック８に吸収させることで、出入り口枠１全体への応力の影響を最小限とし、出入り口枠１の耐久性を向上させることができる。
また、断熱コーナーブロック８，８の延設した部分の室内側端縁に立上り部８ｄを形成し、該立上り部８ｄを沓摺４ａ端部との係合部としたことで、沓摺４ａの両端を閉止し、併せて断熱コーナーブロック８の延設部８ｈを掃出し部８ｍとすることで排水・排塵機能を付与させることができる。
【００１８】
また、特許請求の範囲の記載において、「室外側」及び「室内側」の記載は相対的なものであり、発明の本質を把握するとき、或いは、権利解釈をするときには、「室外側」及び「室内側」の記載は、出入り口枠の「一側」及び「他側」と適宜読み替えるものとする。
なお、特許請求の範囲の記載において、実施例との対応関係を明瞭にするために図面符号を付したが、本発明はこれに限定されるものではない。
【００１９】
【発明の効果】
本発明は、上記構成により次の効果を奏する。
１．請求項１の出入口用断熱サッシは、上枠と縦枠が、アルミニウム合金製の枠部材と、断熱性連結材から成る断熱構造であっても、下枠が一体の非断熱構造を成すので、出入り口枠の耐久力が著しく向上する。また下枠が一体構造であっても、断熱コーナーブロックを介して断熱縦枠と固定するので、従来断熱サッシと同様の断熱効果を維持することができる。
また、障子閉鎖時の気密を向上すると共に、耐久性の向上と施工の簡略化を図ることができ、更に、断熱コーナーブロックには、沓摺にかかる外力による変形を断熱コーナーブロックに吸収させて出入り口枠全体に及ぼさず、出入り口枠全体への応力の影響を最小限とし、出入り口枠の耐久性を向上させることができる。
【００２０】
２．請求項２の出入口用断熱サッシは、上記請求項１の効果に加えて、断熱コーナーブロックの延設部の室内側端縁に立上り部を形成し、立上り部８ｄと縦枠３，３との間を掃出し部８ｍとしたしたことで、沓摺の両端を閉止し、併せて断熱コーナーブロックの延設部に掃き出し機能を付与させることができる。

[Prior art]
The window frame of the sash for cold regions is formed from an aluminum alloy indoor frame member and outdoor frame member, and a heat-insulating connecting member that joins between both frame members, and each side of the shoji frame is made of aluminum alloy. A material formed from a heat-insulating connecting member that is coupled between the indoor-side saddle member, the outdoor-side saddle member, and both the saddle members has also been developed.
That is, a heat insulating structure in which the upper frame and the lower frame constituting the window frame and all of the left and right vertical frames are joined by a heat insulating connecting material (for example, Japanese Patent Laid-Open Nos. 7-62949 and 9-112132). Issue gazette).
[0003]
Assuming that the upper frame, lower frame, and left and right vertical frames that make up the window frame are all heat-insulated with a heat-insulating connecting material, when external force is applied to the window frame, the external force is a heat-insulating connection that has low strength. There has been a problem of concentrating on the material and impairing the coupling between the connecting material and the indoor side frame member or the outdoor side frame member. In addition, the lower frame of the doorway sash has a problem of being damaged or broken because it is stepped on from above or a moving vehicle passes through.

It is another object of the present invention to provide an entrance / exit heat insulating sash capable of improving durability and simplifying construction.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides the following means.
In the heat insulating sash for an entrance / exit according to claim 1, the upper frame 2 and the left and right vertical frames 3, 3 constituting the entrance / exit frame 1 combine an indoor frame member made of aluminum alloy, an outdoor frame member, and both frame members. The lower frame 4 constituting the entrance / exit frame 1 is made of stainless steel and forms a non-insulating structure, and the lower frame 4 and the vertical frames 3 and 3 are provided with the insulating corner blocks 8 and 8. And both ends of the hull 4a extend to the outdoor positions of the left and right vertical frames 3 and 3, and the heat-insulating corner blocks 8, 8 are fixed to each other. Both end portions of the vertical frame 3 and 3 are extended to the space between the outdoor side surface of the vertical frames 3 and 3 and the hull 4a to form an extended portion 8h.
[0006]
The heat insulating sash for an entrance / exit according to claim 2 is characterized in that, in the means of claim 1, a rising portion 8d is formed along the outdoor edge of the extending portion 8h, and the rising portion 8d on the extending portion and a vertical frame are formed.

DETAILED DESCRIPTION OF THE INVENTION
The whole structure of the Example of the heat insulation sash for entrances and exits by this invention is demonstrated based on FIGS. The entrance insulation sash refers to a heat insulation sash used for entrance sashes, front door sashes, bathroom entrances, etc. A semi-external entrance / exit frame, etc.
As shown in FIG. 2, an entrance / exit frame 1 is provided along the inner periphery of the housing opening, in this embodiment, at the entrance-corresponding portion. The entrance / exit frame 1 includes an upper frame 2, vertical frames 3, 3 and a lower frame 4, and is made of an aluminum alloy as a whole. The upper frame 2 includes an indoor-side upper frame member 2a and an outdoor-side upper frame member 2b.
[0008]
The vertical frame 3 includes an indoor vertical frame member 3a and an outdoor vertical frame member 3b. A heat insulating connecting member 15 is interposed between the indoor side upper frame member 2a and the outdoor side upper frame member 2b, and also between the indoor side vertical frame member 3a and the outdoor side vertical frame member 3b. The connecting material 15 is inserted to insulate the inside and outside of the room.
[0009]
However, the lower frame 4 is not composed of two indoor and outdoor members. That is, as shown in FIGS. 3 and 4, the lower frame 4 on which the external force is most exerted due to the weight of the person going in and out is a single box, and forms a long box shape. It is mounted and fixed on the supporting portion 4b. The support portion 4b serves to reinforce the lower frame 4 and to perform positioning at the time of embedding.
Inner and outer rails 5a, 5b and auxiliary rails 5c are formed on the upper surface of the lower frame 4. As will be described later, in this embodiment, the lower frame 4 is formed of a single member, so that the stress resistance is increased and the heat insulating property of the doorway frame 1 as a whole is improved.
Inside the entrance / exit frame 1, the inner / outer shoji 6 and 7 are arranged to be freely opened and closed along the inner rail 5 a and the outer rail 5 b (see FIGS. 3 and 4). Each of the inner and outer shojis 6 and 7 includes an inner shoji 6a and an outer shoji 7a and a multilayer glass 13 supported by the inner and outer shojis 6a and 7a.
[0010]
As shown in FIGS. 3 and 4, the indoor side of the lower frame 4 is formed with an indoor floor surface 20 at substantially the same height as the rail 5 formed on the lower frame 4. Install 4a. The huller 4a is a member that closes or bridges the space between the outdoor floor and the lower frame 4, and is made of an aluminum alloy extruded shape or a steel plate, and its cross section is folded as shown in FIG. It consists of a curved plate.
As shown in FIG. 3, the indoor side edge (right end surface) of the hull 4a is attached to the upper surface of the lower frame 4, and the outdoor side (left end surface) of the hull 4a has substantially the same height as the outdoor floor. It has become.
[0011]
As already described, both ends of the lower frame 4 and the lower ends of the vertical frames 3 and 3 are connected via the heat insulating corner block 8. The heat insulating corner block 8 is made of a synthetic resin having high heat insulation / weather resistance and high mechanical characteristics, and as shown in FIGS. Form.
The upper surface of the heat insulating corner block 8 is a flat portion 8b. The flat portion 8b is provided with corner round portions 8a and 8a on the extended line of the inner and outer rails 5a and 5b, and further, an auxiliary rail adjacent to the outer rail 5b. An airtight material support member 8j for supporting the airtight mohair is provided at a position on the extended line 5c.
[0012]
Further, one side of the heat insulating corner block 8, that is, the lower frame contact surface 8 k that contacts the end of the lower frame 4 communicates with the other side, that is, the vertical frame contact surface 8 l that contacts the lower end of the vertical frame 3. The connection holes 8c, 8c,. Also, an L-shaped rising piece 8 i in plan view is integrally formed at the indoor side end of the heat insulating corner block 8.
[0013]
The outside end of the heat insulating corner block 8 forms an extending portion 8h at a right angle to the flat portion 8b, and forms a rising portion 8d on the outside edge of the extending portion 8h, and further inclines the upper surface. Formed as a portion 8e. Moreover, the recessed part for fitting the edge part of the hull 4a is formed in this outer surface, and it is set as the fitting part 8f.
The indoor side surface of the extended portion 8h is brought into contact with the outdoor side surface of the vertical frame 3. Further, a window-shaped gap 8g parallel to the length direction of the hull 4a is formed in the rising portion 8d.
[0014]
Further, as shown in FIGS. 3 and 4, the heat insulating connecting member 15 is concealed on the inner peripheral side of at least one of the heat insulating connecting member 15 of the upper frame 2 and the heat insulating connecting member 15 of the vertical frames 3 and 3. Install the blindfold 16. All are formed from a synthetic resin excellent in heat insulation. In addition, a windshield plate 9 is attached to the contact portion of the outer panel 7 at the lower part of the vertical frame 3 in order to improve water shielding in addition to airtightness.
[0015]
Further, as shown in FIG. 4, a handle 17 is provided on each of the inner sides of the inner pod 6 a and the outer pod 7 a. Each of the grips 17 and 17 has a gripping portion 17a made of a round bar in the vertical direction, and arm rods 17b and 17b that support the gripping portion 17a up and down are partially bent.
The assembling means of the upper frame 2 and the vertical frame 3 constituting the doorway frame 1 is not different from the conventional one. The lower frame 4 and the heat insulating corner block 8 are connected by inserting bolts (not shown) into the connecting holes 8c and 8c of the left and right heat insulating corner blocks 8 and tightening them. This fastening means is the same as the prior application technique (Japanese Patent Application No. 10-42263) of the present applicant.
[0016]
In the heat insulating sash for the entrance and exit of the above embodiment, the upper frame 2 and the vertical frames 3 and 3 have a heat insulating structure composed of an aluminum alloy frame member and a heat insulating connecting material, but the lower frame 4 is a non-insulating material that is integral. Since the structure is formed, the durability of the entrance / exit frame 1 is remarkably improved. Even if the lower frame 4 has an integral structure, the heat insulating effect can be maintained because it is fixed to the heat insulating vertical frame via the heat insulating corner block 8.
Moreover, while improving the airtightness at the time of closing a shoji, improvement in durability and simplification of construction can be achieved, and further, deformation due to an external force applied to the huller 4a can be absorbed by the heat insulating corner block 8. The influence of the deformation force on the entire entrance / exit frame 1 is reduced.
[0017]
In particular, since the elasticity of the synthetic resin is greater than the metal elasticity, the heat insulating corner block 8 absorbs the deformation of the huller 4a to which the greatest external force is applied, thereby minimizing the influence of stress on the entire entrance / exit frame 1; The durability of the doorway frame 1 can be improved.
Moreover, the rising part 8d is formed in the indoor side edge of the part where the heat insulating corner blocks 8 and 8 are extended, and the rising part 8d is used as an engaging part with the end part of the hull 4a. A drainage / dust removal function can be imparted by closing both ends and combining the extended portion 8h of the heat-insulating corner block 8 with the sweeping portion 8m.
[0018]
Further, in the description of the claims, the descriptions of “outside” and “inside” are relative, and when grasping the essence of the invention or interpreting rights, The description “inside the room” shall be appropriately read as “one side” and “the other side” of the entrance / exit frame.
In addition, in the description of the scope of claims, reference numerals are attached for clarifying the correspondence with the embodiments, but the present invention is not limited to this.
[0019]
【The invention's effect】
The present invention has the following effects by the above configuration.
1. Even if the upper frame and the vertical frame have a heat insulating structure made of an aluminum alloy frame member and a heat insulating connecting material, the lower frame forms an integral non-heat insulating structure. The durability of the entrance / exit frame is significantly improved. Even if the lower frame has an integral structure, it is fixed to the heat insulating vertical frame via the heat insulating corner block, so that the same heat insulating effect as that of the conventional heat insulating sash can be maintained.
In addition to improving the airtightness when closing the shoji, the durability can be improved and the construction can be simplified. In addition, the heat-insulating corner block can absorb the deformation caused by the external force applied to the huller. The influence of the stress on the entire entrance / exit frame can be minimized without affecting the entire entrance / exit frame, and the durability of the entrance / exit frame can be improved.
[0020]
2. In addition to the effect of the first aspect, the heat insulating sash for the entrance / exit of the second aspect forms a rising portion at the indoor side edge of the extending portion of the heat insulating corner block, and the rising portion 8d and the vertical frames 3, 3 Since the gap is set to 8 m, both ends of the hulling can be closed, and at the same time, a sweeping function can be given to the extended portion of the heat insulating corner block.
