特許第5638474号公報Japanese Patent No. 5638474

枠体と補強部材との間に水が浸入しないように、これらの間に水密材を設けることが考えられる。すなわち、第一延出部とヒレ部に挟まれて圧縮された第一部分と、第二延出部と枠体本体に挟まれて圧縮された第二部分と、を有するL字形状の水密材を設けることにより、水の浸入を防ぐことができる。   In order to prevent water from entering between the frame and the reinforcing member, it is conceivable to provide a watertight material between them. That is, an L-shaped water-tight material having a first portion sandwiched and compressed between the first extension portion and the fin portion, and a second portion sandwiched and compressed between the second extension portion and the frame body. Intrusion of water can be prevented by providing.

しかしながら、水密材が枠体と補強部材とに挟まれて過度に圧縮されると、圧縮された水密材の補強部材に対する反発力が大きくなり、補強部材と枠体との間隔が広がって、水が浸入し易くなる課題があった。   However, if the watertight material is sandwiched between the frame body and the reinforcing member and excessively compressed, the repulsive force of the compressed watertight material on the reinforcing member increases, and the interval between the reinforcing member and the frame body increases, and the water There is a problem that makes it easy to penetrate.

本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、枠体と補強部材との間に水が浸入することを適切に抑えることにある。   This invention is made | formed in view of this subject, The place made into the objective is to suppress appropriately permeation of water between a frame and a reinforcement member.

かかる目的を達成するために本発明の建具は、枠体本体と前記枠体本体から延出するヒレ部を有する枠体と、
前記ヒレ部に沿うように延出し、前記ヒレ部を躯体と挟み込んだ状態で締結部材により躯体に締結された第一延出部と、前記第一延出部の一端部から前記枠体本体に沿うように室外側へ向かって延出する第二延出部と、を有するL字形状の補強部材と、
を有する建具であって、
前記第一延出部と前記ヒレ部に挟まれて圧縮された第一部分と、前記第二延出部と前記枠体本体に挟まれて圧縮された第二部分と、を有するL字形状の水密材を備え、
前記第二部分の室外側先端部以外の部分に、圧縮された前記第二部分の前記第二延出部に対する反発力を軽減するための軽減部が設けられていることを特徴とする建具である。
In order to achieve such an object, the joinery of the present invention includes a frame body having a frame body and a fin portion extending from the frame body,
A first extending portion that extends along the fin portion and is fastened to the housing by a fastening member in a state where the fin portion is sandwiched between the housing and an end portion of the first extending portion to the frame body. An L-shaped reinforcing member having a second extending portion extending toward the outdoor side so as to follow,
A joinery having
An L-shape having a first portion compressed between the first extension portion and the fin portion, and a second portion compressed between the second extension portion and the frame body. With watertight material,
A joinery characterized in that a reducing portion for reducing a repulsive force of the compressed second portion against the second extending portion is provided in a portion other than the outdoor front end portion of the second portion. is there.

このような建具によれば、当該軽減部を設けることにより、反発力が全体的に小さくなる。そのため、枠体と補強部材との間隔(第二延出部と枠体本体との間隔)が広がることを抑止し、枠体と補強部材との間に水が浸入することを適切に抑えることが可能となる。   According to such a joinery, the repulsive force is reduced overall by providing the mitigating portion. Therefore, it is possible to prevent the space between the frame body and the reinforcing member (the space between the second extending portion and the frame body) from widening, and appropriately prevent water from entering between the frame body and the reinforcing member. Is possible.

かかる建具であって、
前記軽減部は、穴部であることが望ましい。
Such joinery,
The mitigation part is preferably a hole.

このような建具によれば、反発力を軽減する効果がより大きくなる。そのため、枠体と補強部材との間隔(第二延出部と枠体本体との間隔)が広がることをより抑止し、枠体と補強部材との間に水が浸入することをより適切に抑えることが可能となる。   According to such a joinery, the effect of reducing the repulsive force is further increased. Therefore, the gap between the frame and the reinforcing member (the gap between the second extension portion and the frame main body) is further suppressed, and water can more appropriately enter between the frame and the reinforcing member. It becomes possible to suppress.

かかる建具であって、
前記第二延出部は、前記枠体本体に向かって突出した突出部を有することが望ましい。
Such joinery,
The second extension part preferably has a protrusion protruding toward the frame body.

このような建具によれば、水密材の第二部分の圧縮度合いを作業者によらず一定(一律)とすることができる。そのため、圧縮度合いが過度に大きい状態で作業者が補強部材及び水密材を枠体に取り付けてしまう誤りが起こらなくなる。したがって、水密材の反発力が大きすぎて水の浸入が生じてしまうという不都合の発生を適切に防止することができる。   According to such a joinery, the degree of compression of the second portion of the watertight material can be made constant (uniform) regardless of the operator. Therefore, an error that the operator attaches the reinforcing member and the watertight material to the frame body in a state where the degree of compression is excessively large does not occur. Therefore, it is possible to appropriately prevent the occurrence of inconvenience that the repelling force of the watertight material is too large and water enters.

かかる建具であって、
前記軽減部は、穴部であり、
前記突出部が前記穴部内に位置した状態で前記突出部の先端が前記枠体本体に当接していることが望ましい。

このような建具によれば、直接的に先端が枠体本体に当接するため、先端が枠体本体に当接する感触を作業者が得やすい。そのため、水密材(第二部分)の圧縮度合いを作業者によらず確実に一定(一律)とすることができる。したがって、水密材(第二部分)の反発力が大きすぎて水の浸入が生じてしまうという不都合の発生をより一層適切に防止することができる。   According to such a joinery, since the tip directly contacts the frame body, the operator can easily obtain a feeling that the tip contacts the frame body. Therefore, the degree of compression of the watertight material (second part) can be made constant (uniform) regardless of the operator. Therefore, it is possible to more appropriately prevent the inconvenience that the repelling force of the watertight material (second portion) is too large and water enters.

かかる建具であって、
前記第二延出部は、穴部を備えることが望ましい。
Such joinery,
The second extension part preferably includes a hole.

このような建具によれば、水が、入口から万が一侵入してしまったとしても、躯体に到達する手前で、当該穴部から抜けてくれる。したがって、下枠と補強部材との間に水が浸入してしまったとしても、躯体に水が到達することを抑止することが可能となる。   According to such a joinery, even if water should invade from the entrance, it will come out of the hole before reaching the housing. Therefore, even if water enters between the lower frame and the reinforcing member, it is possible to prevent water from reaching the housing.

かかる建具であって、
前記第二延出部は、該第二延出部の延出方向において前記突出部と隣り合う位置に穴部を備え、
前記突出部は、該穴部よりも室内側に位置することが望ましい。
Such joinery,

<<<下枠32とその周辺の構成について>>>
次に、本実施の形態に係る下枠32とその周辺の構成について、図3乃至図8Bを用いて説明する。なお、図8Aは、下枠32、補強部材60、及び、水密材70を、図6の一点鎖線で切断した切断面を示した図である。
<<< About the structure of the lower frame 32 and its surroundings >>>
Next, the configuration of the lower frame 32 and its periphery according to the present embodiment will be described with reference to FIGS. 3 to 8B. 8A is a diagram showing a cut surface of the lower frame 32, the reinforcing member 60, and the watertight material 70 taken along the one-dot chain line of FIG.

下枠32(枠体20)は、枠体本体の一例としての下枠本体50と、ヒレ部の一例としての下枠ヒレ部52(所謂釘ヒレ)を備えている。   The lower frame 32 (frame body 20) includes a lower frame main body 50 as an example of a frame main body and a lower frame fin portion 52 (so-called nail fin) as an example of a fin portion.

下枠本体50は、障子40の下側に位置し、障子40(外障子40a及び内障子40b)を支持する部分である。   The lower frame main body 50 is a portion that is located below the shoji 40 and supports the shoji 40 (the outer shoji 40a and the inner shoji 40b).

下枠ヒレ部52は、図3に示すように、下枠本体50から延出する延出部分であり、下枠32を躯体80に締結部材の一例としてのネジ82で固定する際の固定部としての機能を有している。この下枠ヒレ部52は、下枠本体50から下方へ、換言すれば、下枠本体50と略直交する直交方向へ延出している。また、下枠ヒレ部52は、下枠32(下枠本体50)の左右方向における一端部から他端部に亘って備えられている。   As shown in FIG. 3, the lower frame fin portion 52 is an extending portion extending from the lower frame main body 50, and a fixing portion when the lower frame 32 is fixed to the housing 80 with a screw 82 as an example of a fastening member. As a function. The lower frame fin portion 52 extends downward from the lower frame main body 50, in other words, in an orthogonal direction substantially orthogonal to the lower frame main body 50. Moreover, the lower frame fin part 52 is provided from the one end part in the left-right direction of the lower frame 32 (lower frame main body 50) to the other end part.

また、下枠本体50及び下枠ヒレ部52には、後述する水密材70を介して補強部材60が取り付けられている。この補強部材60は、枠体20を補強するためのものである。特に、当該補強部材60は、下枠32に対して設けられているため、障子40の重み(障子40にかかる重力)により下枠32(下枠本体50)の室外側の部分(図1において、符号Aで示す部分)が垂れ下がってしまうのを、下枠32(下枠本体50)を支持することで抑止する役割を果たす。なお、本実施の形態において、当該補強部材60は、金属製(ステンレス製)の部材であり、左右方向において等間隔で複数(本実施の形態においては、3つ)設けられている。   Further, a reinforcing member 60 is attached to the lower frame main body 50 and the lower frame fin portion 52 via a watertight material 70 described later. The reinforcing member 60 is for reinforcing the frame body 20. In particular, since the reinforcing member 60 is provided with respect to the lower frame 32, the weight of the shoji 40 (gravity applied to the shoji 40) causes the outdoor portion of the lower frame 32 (lower frame body 50) (in FIG. 1). , The portion indicated by the symbol A) plays a role of inhibiting the lower frame 32 (lower frame body 50) from being supported. In the present embodiment, the reinforcing member 60 is a metal (stainless steel) member, and a plurality (three in the present embodiment) are provided at equal intervals in the left-right direction.

補強部材60は、図4及び図7Aに示すように、L字形状(厳密なL字形を必須とするものではない)を有しており、当該L字形状が互いに略直交する下枠ヒレ部52及び下枠本体50のL字部分に沿うように、下枠ヒレ部52から下枠本体50に亘って取り付けられている。すなわち、補強部材60は、下枠ヒレ部52に沿うように下方へ延出する第一延出部62と、当該第一延出部62の一端部62aから下枠本体50に沿うように室外側へ向かって延出する第二延出部64を備えている。第一延出部62は、下枠ヒレ部52の室外側に位置し、第二延出部64は、下枠本体50の下方に位置している。   As shown in FIGS. 4 and 7A, the reinforcing member 60 has an L-shape (not necessarily requiring a strict L-shape), and the lower frame fin portion in which the L-shapes are substantially orthogonal to each other. 52 and the lower frame main body 50 are attached from the lower frame fin portion 52 to the lower frame main body 50 along the L-shaped portions. That is, the reinforcing member 60 includes a first extending portion 62 that extends downward along the lower frame fin portion 52, and a chamber extending from the one end portion 62 a of the first extending portion 62 along the lower frame main body 50. A second extending portion 64 extending outward is provided. The first extension part 62 is located outside the lower frame fin part 52, and the second extension part 64 is located below the lower frame body 50.

また、下枠ヒレ部52が、下枠32を躯体80にネジ82で固定する際の固定部としての機能を有することを述べたが、当該下枠ヒレ部52は、補強部材60と躯体80とに挟まれた状態で躯体80にネジ止めされている。つまり、図3に示すように、補強部材60の第一延出部62が、下枠ヒレ部52を躯体80と挟み込んだ状態でネジ82により躯体80に締結されている。   In addition, it has been described that the lower frame fin portion 52 has a function as a fixing portion when the lower frame 32 is fixed to the housing 80 with the screw 82. However, the lower frame fin portion 52 includes the reinforcing member 60 and the housing 80. It is screwed to the housing 80 in a state of being sandwiched between the two. That is, as shown in FIG. 3, the first extending portion 62 of the reinforcing member 60 is fastened to the housing 80 by the screw 82 in a state where the lower frame fin portion 52 is sandwiched between the housing 80.

また、下枠32(下枠本体50及び下枠ヒレ部52)と補強部材60との間には、水密材70が設けられている。すなわち、水密材70は、図7Aと図7B(または、図8Aと図8B)を比較することにより明らかなとおり、下枠32(下枠本体50及び下枠ヒレ部52)と補強部材60に挟まれて圧縮されている。なお、本実施の形態において、水密材70は、合成樹脂製(スポンジ製)の部材であり、補強部材60と同様、左右方向において等間隔で複数(本実施の形態においては、3つ)設けられている。   Further, a watertight material 70 is provided between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60. That is, the watertight member 70 is formed on the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60, as is apparent by comparing FIGS. 7A and 7B (or FIGS. 8A and 8B). It is sandwiched and compressed. In the present embodiment, the watertight material 70 is a synthetic resin (sponge) member, and a plurality (three in the present embodiment) are provided at equal intervals in the left-right direction, like the reinforcing member 60. It has been.

この水密材70は、下枠32(下枠本体50及び下枠ヒレ部52)と補強部材60との間に水が浸入するのを抑えるためのものである。   The watertight material 70 is for suppressing water from entering between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60.

具体的に説明すると、図3に示すように、下枠32(下枠本体50)の下側には、外壁84が設けられており、下枠本体50と外壁84の上端との間はシール材86でシールされている。また、補強部材60(第二延出部64)が設けられた位置においても、当該補強部材60(第二延出部64)の下側には外壁84が設けられている。そして、外壁84と補強部材60との間は、シール材86でシールされているため、水密材70が設けられていない場合には、下枠32と補強部材60との間が、外部から水が侵入する唯一の経路となる(外部から水が浸入すると、外壁84よりも室内側に水が入り込んでしまう)。そして、かかる場合には、図3に示すように、下枠本体50、第二延出部64間の入口G1から侵入し出口G2まで移動した水が、出口G2から落下して躯体80を濡らしてしまう可能性がある(また、水が、出口G2まで移動する前に、ネジ82を伝わって躯体80内に侵入してしまう恐れもある)。そこで、このような不都合が生じないように、水密材70が設けられている。   Specifically, as shown in FIG. 3, an outer wall 84 is provided below the lower frame 32 (lower frame main body 50), and a seal is provided between the lower frame main body 50 and the upper end of the outer wall 84. Sealed with a material 86. Even at the position where the reinforcing member 60 (second extending portion 64) is provided, an outer wall 84 is provided below the reinforcing member 60 (second extending portion 64). Since the space between the outer wall 84 and the reinforcing member 60 is sealed with the sealing material 86, when the watertight material 70 is not provided, the space between the lower frame 32 and the reinforcing member 60 is water from the outside. Is the only path through which water enters (if water enters from the outside, the water enters the indoor side of the outer wall 84). In such a case, as shown in FIG. 3, the water that has entered from the inlet G1 between the lower frame main body 50 and the second extending portion 64 and moved to the outlet G2 falls from the outlet G2 and wets the casing 80. (Also, there is a possibility that the water may enter the housing 80 through the screw 82 before moving to the outlet G2). Therefore, a watertight material 70 is provided so as not to cause such inconvenience.

水密材70は、補強部材60と略同様の形状を有している。すなわち、水密材70は、図5及び図7Aに示すように、L字形状(厳密なL字形を必須とするものではない)を有しており、当該L字形状が、互いに略直交する下枠ヒレ部52及び下枠本体50のL字部分と補強部材60のL字形状の双方に沿うように、下枠32(下枠本体50及び下枠ヒレ部52)と補強部材60との間に設けられている。つまり、水密材70は、第一延出部62と下枠ヒレ部52に挟まれて圧縮された第一部分72と、第二延出部64と下枠本体50に挟まれて圧縮された第二部分74とを備えている。   The watertight material 70 has substantially the same shape as the reinforcing member 60. That is, as shown in FIGS. 5 and 7A, the watertight material 70 has an L shape (a strict L shape is not essential), and the L shapes are substantially perpendicular to each other. Between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60 so as to follow both the L-shaped portion of the frame fin portion 52 and the lower frame main body 50 and the L-shape of the reinforcing member 60. Is provided. That is, the watertight material 70 is compressed between the first extension portion 62 and the lower frame fin portion 52 and compressed between the first portion 72 and the second extension portion 64 and the lower frame body 50. And two portions 74.

第一部分72は、第一延出部62と同様、下枠ヒレ部52に沿うように下方へ延出し、また、第二部分74は、第二延出部64と同様、該第一部分72の一端部72aから下枠本体50に沿うように室外側へ向かって延出している。なお、図6及び図7Aに示すように、第一延出部62の延出先端と第一部分72の延出先端の延出方向における位置は一致し、第二延出部64の延出先端と第二部分74の延出先端の延出方向における位置も一致している。   The first portion 72 extends downward along the lower frame fin portion 52, as with the first extension portion 62, and the second portion 74, as with the second extension portion 64, It extends toward the outdoor side along the lower frame main body 50 from the one end 72a. As shown in FIGS. 6 and 7A, the extension tip of the first extension portion 62 and the extension tip of the first portion 72 are aligned in the extension direction, and the extension tip of the second extension portion 64 is the same. And the position in the extending direction of the extending tip of the second portion 74 also coincides.

また、第一延出部62が、下枠ヒレ部52を躯体80と挟み込んだ状態でネジ82により躯体80に締結されていることを述べたが、第一延出部62は、水密材70も挟み込んでいる。すなわち、第一延出部62と躯体80が第一部分72及び下枠ヒレ部52を挟み込んだ状態で第一延出部62がネジ82により躯体80に締結されている。   In addition, it has been described that the first extending portion 62 is fastened to the housing 80 with the screw 82 in a state where the lower frame fin portion 52 is sandwiched between the housing 80, but the first extending portion 62 is formed of the watertight material 70. Is also sandwiched. That is, the first extension portion 62 is fastened to the casing 80 by the screw 82 in a state where the first extension portion 62 and the casing 80 sandwich the first portion 72 and the lower frame fin portion 52.

ところで、水密材70が下枠32(下枠本体50及び下枠ヒレ部52)と補強部材60に挟まれて圧縮されると、圧縮された水密材70の補強部材60に対する反発力(水密材70が補強部材60を押圧する力)が生じる。そして、当該圧縮が過度になると当該反発力が大きくなり、補強部材60と下枠32との間隔が広がって、水が浸入し易くなる問題が生じ得る。特に、本実施の形態においては、第一延出部62と躯体80が第一部分72及び下枠ヒレ部52を挟み込んだ状態で第一延出部62がネジ82により躯体80に締結されているので(すなわち、補強部材60の締結は第一延出部62のみの締結なので)、下枠本体50と第二延出部64との間隔が水密材70の反発力により広がり易くなっている。   By the way, when the watertight material 70 is compressed by being sandwiched between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60, the repulsive force of the compressed watertight material 70 against the reinforcing member 60 (watertight material). Force that 70 presses the reinforcing member 60). When the compression becomes excessive, the repulsive force increases, and the interval between the reinforcing member 60 and the lower frame 32 is widened, which may cause a problem that water can easily enter. In particular, in the present embodiment, the first extension portion 62 and the casing 80 are fastened to the casing 80 by screws 82 in a state where the first portion 72 and the lower frame fin portion 52 are sandwiched. Therefore (that is, the fastening of the reinforcing member 60 is only the fastening of the first extending portion 62), the interval between the lower frame main body 50 and the second extending portion 64 is easily spread by the repulsive force of the watertight material 70.

そこで、図5及び図8Aに示すように、第二部分74の室外側先端部74a以外の部分に、圧縮された第二部分74の第二延出部64に対する反発力を軽減するための軽減部(本実施の形態においては、面積を小さくするための穴部74b)を設けている。つまり、当該軽減部(穴部74b)を設けることにより、反発力の発生部位の面積を減らすことができるから、反発力が全体的に小さくなる。そのため、下枠32と補強部材60との間隔(第二延出部64と下枠本体50との間隔)が広がることを抑止し、下枠32と補強部材60との間に水が浸入することを適切に抑えることが可能となる。   Therefore, as shown in FIG. 5 and FIG. 8A, the reduction for reducing the repulsive force of the compressed second portion 74 against the second extending portion 64 on the portion other than the outdoor tip 74 a of the second portion 74. (In this embodiment, a hole 74b for reducing the area) is provided. In other words, by providing the mitigating portion (hole 74b), the area of the repulsive force generation site can be reduced, so that the repulsive force is reduced as a whole. Therefore, an increase in the distance between the lower frame 32 and the reinforcing member 60 (the distance between the second extending portion 64 and the lower frame main body 50) is suppressed, and water enters between the lower frame 32 and the reinforcing member 60. This can be suppressed appropriately.

一方で、穴部74bを第二部分74の室外側先端部74a以外の部分に設けることとしため、穴部74bを設けたことによる止水能力の低下は発生しない。すなわち、水の侵入経路における入口G1には、穴部74bを設けず水密材70を残してあるので、水の浸入を確実に抑えることができる。   On the other hand, since the hole 74b is provided in a portion other than the outdoor front end portion 74a of the second portion 74, a decrease in water stoppage capability due to the provision of the hole 74b does not occur. That is, since the watertight material 70 is left without providing the hole 74b at the inlet G1 in the water intrusion path, the ingress of water can be reliably suppressed.

なお、本実施の形態に係る穴部74bは、図5に示すように、矩形形状を備えている。そして、見込み方向においては、室外側先端部74aを除いて、(室内側の先端まで)第二部分74の全てに穴部74bが設けられ、左右方向においては、両端部74cを除いて穴部74bが設けられている。   The hole 74b according to the present embodiment has a rectangular shape as shown in FIG. In the prospective direction, the hole 74b is provided in all of the second portion 74 (up to the indoor-side tip) except for the outdoor front end portion 74a, and in the left-right direction, the hole portions excluding both end portions 74c are provided. 74b is provided.

このように、本実施の形態においては、水密材70の反発力を低下させて水の侵入を適切に抑えるために、水密材70に穴部74bを設けている。しかしながら、当該反発力の大きさは、補強部材60及び水密材70を下枠32に取り付ける作業者の取り付け作業により変動し得る。すなわち、補強部材60及び水密材70を下枠32に取り付ける際の水密材70の圧縮度合いが作業者によって異なるため(区々となるため)反発力も異なり、圧縮度合いが過度に大きい状態で作業者が取り付けてしまった場合には、(穴部74bで反発力を低下させたのに)反発力が大きすぎて水の浸入が生じてしまうという不都合が生じ得る。   As described above, in the present embodiment, the hole 74b is provided in the watertight material 70 in order to reduce the repulsive force of the watertight material 70 and appropriately suppress the entry of water. However, the magnitude of the repulsive force can vary depending on the attachment work of the worker who attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32. That is, since the degree of compression of the water-tight material 70 when attaching the reinforcing member 60 and the water-tight material 70 to the lower frame 32 is different depending on the worker (because it is different), the repulsive force is also different, and the worker is in a state where the degree of compression is excessively large. May have the inconvenience that the repulsive force is too great and water permeates (even though the repulsive force is reduced by the hole 74b).

そこで、図4及び図8Aに示すように、補強部材60の第二延出部64に、突出部(本実施の形態においては、切り起こし部64a)を設けている。この切り起こし部64aを第二延出部64に設けたことにより、作業者が、補強部材60及び水密材70を下枠32に取り付ける際に、切り起こし部64aの先端64bが下枠本体50に当接することとなる(図8A参照)。そして、作業者は、当該先端64bが下枠本体50に当接する感触を得ることができるので、図8Aに示すように、当接したところで(当該感触を得たところで)補強部材60をネジ82で固定するようにすれば、第二延出部64の下枠本体50に対する相対位置は作業者によらず一定(一律)となる。そのため、第二延出部64と下枠本体50に挟まれた第二部分74(特に、室外側先端部74a)の圧縮度合いも作業者によらず一定(一律)となる。   Therefore, as shown in FIGS. 4 and 8A, the second extending portion 64 of the reinforcing member 60 is provided with a protruding portion (in the present embodiment, a cut-and-raised portion 64a). By providing the cut-and-raised portion 64 a in the second extending portion 64, when the operator attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32, the tip 64 b of the cut-and-raised portion 64 a has the lower frame main body 50. (See FIG. 8A). Then, the operator can obtain a feeling that the tip 64b contacts the lower frame body 50. Therefore, as shown in FIG. 8A, the worker attaches the reinforcing member 60 to the screw 82 when the contact is made (when the feeling is obtained). If it fixes by this, the relative position with respect to the lower frame main body 50 of the 2nd extension part 64 will become fixed (uniform) irrespective of an operator. Therefore, the degree of compression of the second portion 74 (particularly, the outdoor front end portion 74a) sandwiched between the second extending portion 64 and the lower frame main body 50 is also constant (uniform) regardless of the operator.

このように、本実施の形態においては、図8Aに示したように、第二延出部64が下枠本体50に向かって突出した突出部(切り起こし部64a)を備えるようにしたため、第二部分74(室外側先端部74a)の圧縮度合いを作業者によらず一定(一律)とすることができる(前記圧縮度合いの作業者によるばらつきを解消することができる)。そのため、圧縮度合いが過度に大きい状態で作業者が補強部材60及び水密材70を下枠32に取り付けてしまう誤りが起こらなくなる。したがって、水密材70(第二部分74)の反発力が大きすぎて水の浸入が生じてしまうという不都合の発生を適切に防止することができる。   Thus, in the present embodiment, as shown in FIG. 8A, the second extending portion 64 includes the protruding portion (cut-raised portion 64a) protruding toward the lower frame body 50. The degree of compression of the two portions 74 (outdoor tip 74a) can be made constant (uniform) regardless of the operator (variation of the compression degree by the operator can be eliminated). Therefore, an error in which the operator attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32 in a state where the degree of compression is excessively large does not occur. Therefore, it is possible to appropriately prevent the occurrence of inconvenience that the repelling force of the watertight material 70 (second portion 74) is too large and water enters.

なお、本実施の形態においては、切り起こし部64aは矩形形状を備えており、図8Aに示すように、切り起こし部64aが穴部74b内に位置した状態で切り起こし部64aの先端64bが下枠本体50に当接している。つまり、切り起こし部64aの左右方向における両端は、穴部74bの左右方向における両端よりも内側に位置し、切り起こし部64aの見込み方向における両端は、穴部74bの見込み方向における両端よりも内側に位置している。そのため、作業者が、補強部材60及び水密材70を下枠32に取り付ける際には、切り起こし部64aが穴部74b内に挿入されることとなる。   In the present embodiment, the cut and raised portion 64a has a rectangular shape, and as shown in FIG. 8A, the tip 64b of the cut and raised portion 64a is located with the cut and raised portion 64a positioned in the hole 74b. It is in contact with the lower frame body 50. That is, both ends in the left-right direction of the cut-and-raised portion 64a are located inside both ends in the left-right direction of the hole 74b, and both ends in the expected direction of the cut-and-raised portion 64a are inside of both ends in the expected direction of the hole 74b. Is located. Therefore, when the worker attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32, the cut and raised portion 64a is inserted into the hole portion 74b.

また、本実施の形態においては、先端64bが下枠本体50に当接する際の第二部分74(具体的には、室外側先端部74a)の圧縮度合い(以下、当接時圧縮率と呼ぶ)が、水密材70の仕様上の適正圧縮度合い(以下、適正圧縮率と呼ぶ)と等しいか、それよりも高くなるように設定されている。ここで、当該適正圧縮率とは、水密材70の止水能力を適正に発揮させるために最低限必要な圧縮度合いである。つまり、当該適正圧縮率が例えば60%であるとすれば、当接時圧縮率を60%か60%よりも高くなるように設定している。なお、水密材70は圧縮率を過度に高くすると、前記反発力が上昇してしまう。そのため、かかる事項を考慮すると、当接時圧縮率を、適正圧縮率に略等しく設定するのが望ましい。   In the present embodiment, the degree of compression of the second portion 74 (specifically, the outdoor front end portion 74a) when the front end 64b contacts the lower frame main body 50 (hereinafter referred to as a contact compression rate). ) Is set to be equal to or higher than an appropriate compression degree (hereinafter referred to as an appropriate compression rate) in the specification of the watertight material 70. Here, the said appropriate compression rate is a minimum compression required in order to exhibit the water stop capability of the watertight material 70 appropriately. That is, if the appropriate compression rate is 60%, for example, the contact compression rate is set to be 60% or higher than 60%. In addition, if the watertight material 70 makes a compression rate high too much, the said repulsive force will raise. Therefore, in consideration of such matters, it is desirable to set the compression rate at the time of contact substantially equal to the appropriate compression rate.

このように、本実施の形態においては、第二部分74(室外側先端部74a)の圧縮度合いを作業者によらず一定(一律)とすることにより、水密材70(第二部分74)の反発力が大きすぎて水の浸入が生じてしまうという不都合の発生を適切に防止するとともに、作業者によらず所望の止水能力を確実に発揮させることもできる。   As described above, in the present embodiment, the degree of compression of the second portion 74 (outdoor tip 74a) is constant (uniform) regardless of the operator, so that the water-tight material 70 (second portion 74) It is possible to appropriately prevent the inconvenience that the repulsion force is too large and cause the invasion of water, and it is possible to reliably exhibit the desired water stopping ability regardless of the operator.

本実施の形態においては、水の浸入防止及び適切な止水能力の発揮を実現するために、補強部材60の第二延出部64に切り起こし64aを設けたが、このことにより、当該第二延出部64には、図4及び図8Aに示すように、穴部が生ずる。そして、当該穴部は、水抜き穴66としての機能を発揮する。つまり、本実施の形態においては、当該水抜き穴66が設けられているため、水が、入口G1から万が一侵入してしまったとしても、躯体80に到達する手前で、当該水抜き穴66から抜けてくれる(落下してくれる。落下する様子を図8Aに白矢印で示す)。したがって、下枠32と補強部材60との間に水が浸入してしまったとしても、躯体80に水が到達することを抑止することが可能となる。   In the present embodiment, in order to prevent the intrusion of water and to exhibit an appropriate water stopping capability, the second extending portion 64 of the reinforcing member 60 is provided with the cut and raised portions 64a. As shown in FIGS. 4 and 8A, a hole is formed in the two extending portions 64. The hole portion functions as a drain hole 66. That is, in the present embodiment, since the water drain hole 66 is provided, even if water has entered from the entrance G1, the water drain hole 66 is just before reaching the housing 80. It will come out (it will fall down. The state of falling is indicated by a white arrow in FIG. 8A). Therefore, even if water has entered between the lower frame 32 and the reinforcing member 60, it is possible to prevent water from reaching the housing 80.

なお、本実施の形態においては、図4に示すように、水抜き穴66として、3箇所の水抜き穴(便宜上、第一水抜き穴66a、第二水抜き穴66b、第三水抜き穴66cと呼ぶ)が備えられている。いずれの水抜き穴66も、水密材70の穴部74bに対応した位置に設けられている。   In the present embodiment, as shown in FIG. 4, three drain holes (for convenience, the first drain hole 66a, the second drain hole 66b, and the third drain hole are provided as the drain holes 66. 66c). Any drainage hole 66 is provided at a position corresponding to the hole 74 b of the watertight material 70.

切り起こし部64aの先端64bが切り起こし部64aの支点64cよりも見込み方向において室外側に位置するように形成されているため、第一水抜き穴66aは、第二延出部64の延出方向(見込み方向)において切り起こし部64aと隣り合い、かつ、切り起こし部64aよりも室外側に位置している。また、第二水抜き穴66b及び第三水抜き穴66cは、左右方向において切り起こし部64aと隣り合い、かつ、切り起こし部64aよりも外側に位置している。   Since the tip 64b of the cut-and-raised part 64a is formed so as to be positioned on the outdoor side in the prospective direction with respect to the fulcrum 64c of the cut-and-raised part 64a, the first drain hole 66a extends from the second extending part 64. It is adjacent to the cut-and-raised portion 64a in the direction (expected direction) and is located outside the cut-and-raised portion 64a. The second drain hole 66b and the third drain hole 66c are adjacent to the cut and raised portion 64a in the left-right direction and are located outside the cut and raised portion 64a.

===その他の実施形態===
上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更・改良され得ると共に、本発明には、その等価物が含まれることは言うまでもない。
=== Other Embodiments ===
The above-described embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified and improved without departing from the gist thereof, and it goes without saying that the present invention includes equivalents thereof.

上記実施の形態においては、建具として、引き違い窓10を例に挙げて説明したが、これに限定されるものではなく、枠体を有する建具であればどのようなものでも構わない。   In the said embodiment, although the sliding window 10 was mentioned as an example and demonstrated as a fitting, it is not limited to this, What kind of thing may be used if it is a fitting with a frame.

また、上記実施の形態においては、補強部材60及び水密材70を設ける枠体20として下枠32(下枠本体50及び下枠ヒレ部52)を例に挙げて説明したが、これに限定されるものではない。例えば、上枠30(上枠本体30a及び上枠ヒレ部30b)や縦枠35(縦枠本体35a及び縦枠ヒレ部35b)に対して設けることとしてもよい。すなわち、本発明は、下枠32に対して設けられる補強部材60及び水密材70だけでなく上枠30や縦枠35に対して設けられる補強部材60及び水密材70に適用することも可能である。   Moreover, in the said embodiment, although the lower frame 32 (lower frame main body 50 and lower frame fin part 52) was mentioned as an example and demonstrated as the frame 20 which provides the reinforcement member 60 and the watertight material 70, it is limited to this. It is not something. For example, it is good also as providing with respect to the upper frame 30 (the upper frame main body 30a and the upper frame fin part 30b) and the vertical frame 35 (the vertical frame main body 35a and the vertical frame fin part 35b). That is, the present invention can be applied not only to the reinforcing member 60 and the watertight material 70 provided for the lower frame 32 but also to the reinforcing member 60 and the watertight material 70 provided for the upper frame 30 and the vertical frame 35. is there.

また、上記実施の形態においては、反発力を軽減するための軽減部として穴部74bを設けることとしたが、これに限定されるものではない。例えば、穴部74bの代わりに、水密材70の厚みが他の箇所よりも薄い薄厚部を設けることとしてもよい。   Moreover, in the said embodiment, although the hole 74b was provided as a reduction part for reducing repulsive force, it is not limited to this. For example, it is good also as providing the thin part whose thickness of the watertight material 70 is thinner than another location instead of the hole 74b.

ただし、軽減部を穴部74bとした方が、薄厚部とするよりも反発力を軽減する効果がより大きいため、かかる点で、上記実施の形態の方が望ましい。   However, since the effect of reducing the repulsive force is greater when the reduction part is the hole part 74b than when it is a thin part, the above embodiment is preferable in this respect.

また、上記実施の形態においては、前記軽減部が穴部74bであり、突出部(切り起こし部64a)が穴部74b内に位置した状態で突出部(切り起こし部64a)の先端64bが下枠本体50に当接していることとしたが、これに限定されるものではない。例えば、当該軽減部が前記薄厚部である場合には、突出部(切り起こし部64a)の先端64bが、薄厚部を間に挟んだ状態で下枠本体50に当接することとしてもよい。   Further, in the above embodiment, the mitigating portion is the hole 74b, and the tip 64b of the protruding portion (cut-raised portion 64a) is in the lower position while the protruding portion (cut-raised portion 64a) is positioned in the hole 74b. Although it is in contact with the frame main body 50, it is not limited to this. For example, when the mitigating part is the thin part, the tip 64b of the projecting part (cut-and-raised part 64a) may be in contact with the lower frame body 50 with the thin part interposed therebetween.

ただし、上記実施の形態においては、直接的に先端64bが下枠本体50に当接するため、先端64bが下枠本体50に当接する感触を作業者が得やすい。そのため、第二部分74(室外側先端部74a)の圧縮度合いを作業者によらず確実に一定(一律)とすることができる。したがって、水密材70(第二部分74)の反発力が大きすぎて水の浸入が生じてしまうという不都合の発生をより一層適切に防止することができる。かかる点で、上記実施の形態の方が望ましい。   However, in the above-described embodiment, the tip 64b directly contacts the lower frame main body 50, so that the operator can easily feel that the tip 64b contacts the lower frame main body 50. Therefore, the degree of compression of the second portion 74 (outdoor tip 74a) can be made constant (uniform) regardless of the operator. Therefore, it is possible to more appropriately prevent the occurrence of inconvenience that the repelling force of the watertight material 70 (second portion 74) is too large to cause water intrusion. In this respect, the above embodiment is preferable.

また、上記実施の形態においては、図8Aに示したように、切り起こし部64aの先端64bが切り起こし部64aの支点64cよりも見込み方向において室外側に位置するように形成されていた。そのため、第二延出部64は、第二延出部64の延出方向(見込み方向)において切り起こし部64aと隣り合う位置に水抜き穴66(すなわち、第一水抜き穴66a)を備え、切り起こし部64aは第一水抜き穴66aよりも室内側に位置することとした。   Moreover, in the said embodiment, as shown to FIG. 8A, it formed so that the front-end | tip 64b of the cut-and-raised part 64a might be located in the outdoor side in a prospective direction rather than the fulcrum 64c of the cut-and-raised part 64a. Therefore, the second extending portion 64 includes a drain hole 66 (that is, the first drain hole 66a) at a position adjacent to the cut and raised portion 64a in the extending direction (expected direction) of the second extending portion 64. The cut-and-raised portion 64a is located on the indoor side of the first drain hole 66a.

しかしながら、これに限定されるものではなく、例えば、図9に示すように、切り起こし部64aの先端64bが切り起こし部64aの支点64cよりも見込み方向において室内側に位置するように形成され、切り起こし部64aが第一水抜き穴66aよりも室外側に位置することとしてもよい。   However, the present invention is not limited to this. For example, as shown in FIG. 9, the tip 64b of the cut-and-raised portion 64a is formed to be positioned on the indoor side in the prospective direction with respect to the fulcrum 64c of the cut-and-raised portion 64a. The cut-and-raised portion 64a may be located on the outdoor side of the first drain hole 66a.

ただし、上記実施の形態においては、建物等の建設中に外壁84及びシール材86が存在しないときや建設後においてシール材86が不測の事態により破れてしまったとき等に、水しぶきが万が一下側から上方に向けて飛んで、第一水抜き穴66aから入ったとしても(図8Aにおいて右上へ向かう黒矢印参照)、下枠本体50に当接している切り起こし部64aの先端64bが当該水しぶきをブロックするため、水しぶきの躯体80側(室内側)への移動を回避することが可能となる。かかる点で、上記実施の形態の方が望ましい。   However, in the above embodiment, when the outer wall 84 and the sealing material 86 are not present during construction of the building or the like, or when the sealing material 86 is torn due to an unforeseen situation after construction, the splash should be on the lower side. Even if it flies upward from the top and enters through the first drain hole 66a (see the black arrow heading to the upper right in FIG. 8A), the tip 64b of the cut-and-raised portion 64a that is in contact with the lower frame body 50 is sprayed. Therefore, it is possible to avoid the movement of the splash toward the housing 80 (inside the room). In this respect, the above embodiment is preferable.

また、上記実施の形態においては、第二延出部64の突出部として切り起こし部64aを例に挙げて説明したが、これに限定されるものではない。例えば、第二延出部64を切るのではなく、第二延出部64の一方面を凹ませ他方面を膨らませて第二延出部64に突出部としての凸部を形成することとしてもよい。   Moreover, in the said embodiment, although the cut and raised part 64a was mentioned as an example as a protrusion part of the 2nd extension part 64, it was not limited to this. For example, instead of cutting the second extending portion 64, one surface of the second extending portion 64 may be recessed and the other surface expanded to form a convex portion as a protruding portion in the second extending portion 64. Good.

ただし、突出部を切り起こし部64aとすることにより、自動的に水抜き穴66が形成されるため、水抜き穴66を別途形成する必要がなくなるというメリットが生じる点で、上記実施の形態の方が望ましい。   However, since the drain hole 66 is automatically formed by cutting and raising the protruding portion 64a, there is a merit that it is not necessary to form the drain hole 66 separately. Is preferable.
