Description

本発明は、樹脂製窓枠と窓框間の気密構造に関する。 The present invention relates to an airtight structure between a resin window frame and a window ridge.

室内外を連通する建物開口部に設けられた窓枠と、窓枠内に相対移動可能に配設された障子における窓框との間から、風雨や塵埃等が室内に侵入するのを抑制する気密構造は公知である(例えば、特許文献１参照)。 Suppresses intrusion of wind, rain, dust, etc. into the room from between the window frame provided at the opening of the building that communicates indoors and outdoors, and the window fence in the shoji that is arranged to be relatively movable within the window frame. The airtight structure is known (see, for example, Patent Document 1).

引用文献１においては、図６に示すように、窓枠２０の枠内側である、下枠２１の内周端面に前後２列のレール２１ａが設けられ、上枠２２および左右の縦枠(図示せず)における内周端面には、突条２２ａが設けられている。下枠２１の前後のレール２１ａ、２１ａ間には、ブラシ状のシール部材２１ｂが設けられている。 In Cited Document 1, as shown in FIG. 6, two rows of rails 21 a are provided on the inner peripheral end surface of the lower frame 21, which is the inner side of the window frame 20, and the upper frame 22 and the left and right vertical frames (see FIG. 6). A protrusion 22a is provided on the inner peripheral end face of the not shown. Between the rails 21a and 21a before and after the lower frame 21, a brush-like seal member 21b is provided.

窓枠２０内には、室内側の内障子２３、および室外側の外障子２４が引違い状態に配設されている。内障子２３および外障子２４の外周部に設けられた窓框２５の外周端面における召合わせ部を除く部分に、窓枠２０のレール２１ａ、および突条２２ａを相対移動可能に嵌入しうる凹溝２６が設けられている。窓框２５の下框２７における長手方向の両端近傍には、レール２１ａ上を走行する戸車２７ａが、その下半分を凹溝２６内に露呈させて設けられている。 Inside the window frame 20, an indoor shroud 23 and an outdoor shroud 24 are arranged in a closed state. A groove that allows the rail 21a and the ridge 22a of the window frame 20 to be fitted to be movable relative to a portion other than the summing portion on the outer peripheral end face of the window ledge 25 provided on the outer peripheral portions of the inner and outer children 23 and 24. 26 is provided. In the vicinity of both ends in the longitudinal direction of the lower casing 27 of the window casing 25, a door wheel 27a running on the rail 21a is provided with its lower half exposed in the concave groove 26.

窓框２５の凹溝２６における前後の壁部２８には、図７に示すように、凹溝２６の内側に向けて開口する奥広がりの嵌合溝２９が設けられ、この嵌合溝２９に気密部材３０が嵌合されている。 As shown in FIG. 7, the front and rear wall portions 28 of the recessed groove 26 of the window lamp 25 are provided with a fitting groove 29 that extends toward the inside of the recessed groove 26. The airtight member 30 is fitted.

気密部材３０は、一般にモヘヤ、ゴム、ビード、エラストマ等によって形成され、先端部がブラシ状またはヒレ状等に形成されている。気密部材３０の先端部を、窓枠２０におけるレール２１ａ、および突条２２ａの側面に接触させることにより、窓枠２０と窓框２５との間の気密状態を保持し、室内に風雨や塵埃等が進入するのを抑制することができる。 The airtight member 30 is generally formed of mohair, rubber, bead, elastomer, or the like, and the tip is formed in a brush shape or a fin shape. The tip of the airtight member 30 is brought into contact with the rail 21a of the window frame 20 and the side surfaces of the protrusions 22a, so that the airtight state between the window frame 20 and the window rod 25 is maintained.

特開２００５−２６４４９５号公報JP 2005-264495 A

しかし、特許文献１においては、窓框２５における気密部材３０を嵌合する嵌合溝２９が、横向き、すなわち、凹溝２６の溝底から開口に至る凹溝中心軸線Ｌ３とほぼ直交し、かつ凹溝２６の内側を向くように開口されている。そのため、気密部材３０を嵌合溝２９に嵌合して取付ける際に、凹溝２６内において嵌合作業をすることとなり、凹溝２６の前後の壁部２８が邪魔となり、狭い凹溝２６内での取付作業であるため、作業が困難で、効率が悪い。 However, in Patent Document 1, the fitting groove 29 for fitting the airtight member 30 in the window tub 25 is lateral, that is, substantially perpendicular to the groove center axis L3 extending from the groove bottom to the opening of the groove 26, and An opening is made so as to face the inside of the concave groove 26. Therefore, when fitting the airtight member 30 in the fitting groove 29, fitting work is performed in the concave groove 26, and the wall portions 28 before and after the concave groove 26 become an obstacle, and the narrow concave groove 26 Since it is a mounting operation at, work is difficult and inefficient.

また、断熱効果と防音効果上から、近年、樹脂製の窓枠、窓框が多く採用されてきているが、このような樹脂製の窓框２５を用いる場合、窓框２５の製造時において、窓框２５における左右の縦框材と上下の横框材とを相互に押圧して溶着する際に、その溶着部分である凹溝２６および嵌合溝２９の長手方向の両端部にバリが発生する。このバリのうち、框材の外側面に発生するバリの除去は、比較的容易であるが、凹溝２６の内部、特に嵌合溝２９のバリを除去するのは極めて困難である。 In addition, from the viewpoint of heat insulation effect and soundproofing effect, many resin window frames and window tiles have been adopted in recent years, but when using such a resin window fence 25, when manufacturing the window fence 25, When the left and right vertical frame members and the upper and lower horizontal frame materials are pressed against each other and welded in the window frame 25, burrs are generated at both ends in the longitudinal direction of the recessed groove 26 and the fitting groove 29 which are the welded portions. To do. Of these burrs, it is relatively easy to remove burrs generated on the outer surface of the brazing material, but it is extremely difficult to remove burrs inside the recessed grooves 26, particularly the fitting grooves 29.

そのため、嵌合溝２９や凹溝２６の内部に発生したバリ除去は行わず、縦框材と横框材それぞれに別個に気密部材３０が取付けられている。このため、窓框２５のコーナ部において気密部材３０が不連続となり、気密性が低下しているのが現状である。 For this reason, the burr generated in the fitting groove 29 and the concave groove 26 is not removed, and the airtight member 30 is separately attached to each of the vertical hook material and the horizontal hook material. For this reason, the airtight member 30 becomes discontinuous in the corner portion of the window fence 25, and the current state is that the airtightness is lowered.

本発明は、上記問題点に鑑みてなされたもので、気密部材を窓框の嵌合溝に簡単に嵌合することができ、気密部材の取付作業の効率を向上させることができるとともに、樹脂製の窓框の製造時に凹溝内や嵌合溝の長手方向の両端部に発生するバリを、簡単に除去することができ、窓框のコーナ部において、縦横框材の両者に亘って連続して気密部材を取付けることを可能として、気密性を向上することができる樹脂製窓枠と窓框間の気密構造を提供することを目的とする。 The present invention has been made in view of the above problems, and can easily fit the hermetic member into the fitting groove of the window ridge, improve the efficiency of the mounting operation of the hermetic member, and resin. The burr generated in the concave groove and both ends in the longitudinal direction of the fitting groove can be easily removed during the manufacture of the window jar made of metal, and it is continuous over both the vertical and horizontal ridges at the corner of the window jar. Thus, an object of the present invention is to provide an airtight structure between a resin window frame and a window ridge that can attach an airtight member and can improve the airtightness.

本発明によると、上記課題は、次のようにして解決される。
(１) 室内外を連通する建物開口部に取付けられる樹脂製窓枠であって、枠内側の内周端面に、樹脂製窓枠を構成する枠材の長手方向に延びる突条が設けられた樹脂製窓枠と、この樹脂製窓枠内に配設される障子を構成する窓框であって、外周端面に、樹脂製窓枠の前記突条を相対移動可能に嵌入しうる凹溝が設けられた窓框とを備え、窓框に取付けた気密部材を樹脂製窓枠の前記突条に当接させることにより気密性の向上を図るようにした樹脂製窓枠と窓框との間の気密構造において、
気密部材を取付けるための嵌合溝を、窓框の前記凹溝を形成する室内外方向の前後壁の少なくとも一方の凹溝内側に、前記嵌合溝の溝底から開口部に至る溝中心軸線を、前記凹溝の溝底から開口に至る嵌合中心軸線に対して傾斜して延びるように位置させて、前記開口部の開口幅よりも奥部が幅広なものとして、窓框を構成する框材の長手方向に沿って設けるとともに、気密部材を、框材の長手方向に延びる閉塞部と、この閉塞部における室内外方向の一端裏側に設けた、係止爪を有する取付部と、他端に設けた弾性変形可能な当接部とより構成し、前記取付部を前記嵌合溝内に嵌合させて、前記係止爪を前記嵌合溝における奥部の幅広溝の両側前端縁から相互に近接するように延設させた係止片の端縁に係止させることにより、気密部材を嵌合溝に取付けた状態において、気密部材の前記閉塞部を、樹脂製窓枠の前記突条に対して、ほぼ直交して接近するように湾曲させた形状となし、かつ弾性変形可能な前記当接部を樹脂製窓枠の前記突条の側面に当接させたことを特徴とする樹脂製窓枠と窓框間の気密構造とする。 According to the present invention, the above problem is solved as follows.
(1) A resin window frame attached to a building opening that communicates indoors and outdoors, provided with a protrusion extending in the longitudinal direction of the frame material constituting the resin window frame on the inner peripheral end surface inside the frame. A window frame constituting a resin window frame and a shoji disposed in the resin window frame, and a concave groove into which the protrusions of the resin window frame can be relatively moved are fitted on the outer peripheral end surface. Between the resin-made window frame and the window ridge, which is provided with a provided window ridge and is designed to improve hermeticity by bringing an air-tight member attached to the window ridge into contact with the protrusion of the resin-made window frame. In the airtight structure of
A groove central axis extending from the groove bottom to the opening of the fitting groove on the inner side of at least one of the front and rear walls in the indoor / outdoor direction that forms the concave groove of the window tub Is positioned so as to extend obliquely with respect to the fitting central axis extending from the groove bottom to the opening of the concave groove, and the inner portion is wider than the opening width of the opening portion, so that the window lamp is configured. Provided along the longitudinal direction of the brazing material, and an airtight member, a closed portion extending in the longitudinal direction of the brazing material, an attachment portion having a locking claw provided on one back side in the indoor / outdoor direction of this closed portion, and others And an elastically deformable abutting portion provided at an end, the fitting portion is fitted into the fitting groove, and the engaging claws are fitted to the front end edges of the wide groove at the back of the fitting groove. The airtight member by locking it to the edge of the locking piece extending so as to be close to each other In the state where it is attached to the groove, the closed portion of the airtight member has a shape curved so as to approach substantially perpendicularly to the protrusions of the resin window frame and is elastically deformable. The airtight structure between the resin window frame and the window ridge is characterized in that the contact portion is brought into contact with the side surface of the protrusion of the resin window frame.

このような構成とすると、窓框における凹溝の前後壁の少なくとも一方の凹溝内側に設けた嵌合溝の開口部は、凹溝の開口外側に向けて開口しているため、嵌合溝に気密部材を嵌合させて取付けるとき、嵌合作業の手作業を実質的に凹溝の外側で簡単に行うことができ、手間を省くことができる。 With such a configuration, since the opening of the fitting groove provided on the inner side of at least one of the front and rear walls of the groove in the window ridge opens toward the outer side of the groove, the fitting groove When the airtight member is fitted and attached, the manual operation of the fitting operation can be easily performed substantially outside the concave groove, and labor can be saved.

また、樹脂製の窓框においては、窓框の上下の框材と左右の框材とを溶着によって接合するときに、上下の框材と左右の框材における嵌合溝の長手方向の両端部に発生するバリを、凹溝の外側から簡単に除去することができる。 Further, in the case of a resin-made window rod, when the upper and lower frame members of the window frame and the left and right frame materials are joined by welding, both end portions in the longitudinal direction of the fitting grooves in the upper and lower frame materials and the left and right frame materials Can be easily removed from the outside of the groove.

さらに、気密部材の取付部における係止爪を嵌合溝の係止片縁に係止させることにより、気密部材を嵌合溝に確実に取付けることができる。また、気密部材の当接部を、突条の側面に弾発的に当接させることができるので、さらに良好に樹脂製窓枠と窓框間の気密性の向上を図ることができる。 Furthermore, the airtight member can be reliably attached to the fitting groove by engaging the engaging claw in the attaching portion of the airtight member with the engaging piece edge of the fitting groove. In addition, since the contact portion of the airtight member can be elastically contacted with the side surface of the ridge, the airtightness between the resin window frame and the window ridge can be further improved.

さらにまた、気密部材の閉塞部によって、当接部を樹脂製窓枠の突条にほぼ直交する方向から接近させて当接させることができるため、当接部と突条との当接力を大とすることができ、さらに良好に気密性の向上を図ることができる。Furthermore, since the contact portion can be brought into contact with the protrusion of the resin window frame from the direction substantially perpendicular by the closed portion of the airtight member, the contact force between the contact portion and the protrusion can be increased. In addition, the airtightness can be improved more favorably.

このような構成とすると、嵌合溝の開口部を確実に凹溝の外側に向けて開口させることができる。 With such a configuration, the opening of the fitting groove can be reliably opened toward the outside of the groove.

(５) 上記（１）項〜（４）項のいずれかにおいて、気密部材を取付ける嵌合溝における奥部の幅広溝の両側前端縁から係止片を相互に近接するように延設し、両係止片の端縁間を開口部とすることにより、開口部の開口幅よりも奥部が幅広な嵌合溝を形成するとともに、前記両係止片を、嵌合溝の溝底から開口部に至る溝中心軸線とほぼ直交する平面上に位置させる。 (5) In any one of the above items (1) to (4), the locking pieces are extended so as to be close to each other from the front end edges on both sides of the wide groove at the back of the fitting groove for attaching the airtight member, By forming an opening between the end edges of both locking pieces, a fitting groove having a width wider than the opening width of the opening is formed, and the both locking pieces are separated from the groove bottom of the fitting groove. It is located on a plane that is substantially orthogonal to the groove center axis that reaches the opening.

このような構成とすると、気密部材を嵌合溝に取付ける作業が一層容易になる。 With such a configuration, the work of attaching the airtight member to the fitting groove is further facilitated.

内障子２および外障子３には、複層ガラス１８が装着されている。図４に示すように、窓框１０の外周端面に設けられた凹溝１４内には、気密部材１５を取付けるための嵌合溝１６が設けられている。本発明は、この嵌合溝１６を設ける形態に特徴を有し、併せて前記嵌合溝１６に取付ける気密部材１５の形態にも特徴を有する。 A multi-layer glass 18 is attached to the inner shoji 2 and the outer shoji 3. As shown in FIG. 4, a fitting groove 16 for attaching an airtight member 15 is provided in the recessed groove 14 provided on the outer peripheral end surface of the window tub 10. The present invention has a feature in the form of providing the fitting groove 16, and also has a feature in the form of the airtight member 15 attached to the fitting groove 16.

本発明の嵌合溝１６は、図４、図５に示すように、窓框１０の凹溝１４を形成する室内外方向の前後壁１７の少なくとも一方の凹溝内側に、溝底１６ａから嵌合溝１６の開口部１６ｂに至る溝中心軸線Ｌ１を、前記凹溝内側から凹溝１４の開口外側に向けて傾斜して延びるように位置させてある。
溝中心軸線Ｌ１の傾斜の程度は、凹溝１４の溝底１４ａから開口１４ｂに至る凹溝中心軸線Ｌ２に対する角度θが、３０度から６０度の範囲内となることが望ましく、特に３０度から５０度の範囲内が好ましい。
嵌合溝１６は、凹溝１４を形成する前後壁１７における、凹溝１４の開口端またはその近傍に設けることが好ましい。 As shown in FIGS. 4 and 5, the fitting groove 16 of the present invention is fitted from the groove bottom 16 a inside at least one of the front and rear walls 17 in the indoor / outdoor direction that forms the concave groove 14 of the window lamp 10. The groove center axis L1 reaching the opening 16b of the joint groove 16 is positioned so as to extend obliquely from the inside of the recessed groove toward the outside of the opening of the recessed groove 14.
The degree of inclination of the groove center axis L1 is preferably such that the angle θ with respect to the groove center axis L2 from the groove bottom 14a to the opening 14b of the groove 14 is in the range of 30 to 60 degrees, particularly from 30 degrees. A range of 50 degrees is preferable.
The fitting groove 16 is preferably provided at or near the opening end of the concave groove 14 in the front and rear wall 17 that forms the concave groove 14.

嵌合溝１６を前記のような形態で設けることにより、図７に示す従来の場合よりも、気密部材１５の嵌合溝１６への取付の手作業を実質的に凹溝１４の外側で簡単に行うことができるため作業効率が格段に向上するとともに、窓框１０における横框材と縦框材が当接する角部において発生する溶着時に発生するバリの除去を簡単に行うことができる。 By providing the fitting groove 16 in the form as described above, the manual operation of attaching the airtight member 15 to the fitting groove 16 is substantially easier outside the concave groove 14 than in the conventional case shown in FIG. Therefore, the working efficiency is remarkably improved, and burrs generated at the time of welding generated at the corners where the horizontal frame material and the vertical frame material are in contact with each other can be easily removed.

すなわち、従来の場合は、嵌合溝２９が凹溝２６内に向けて開口しているために、気密部材３０の取付作業を凹溝２６内で行わなければならず、狭い凹溝２６内では手作業の自由度が拘束されるばかりでなく、嵌合溝２９の開口部の位置の確認も手さぐり状態となって、極めて気密部材３０の嵌合溝２９への取付作業は効率の悪いものであった。
特に、バリの除去作業は、バリの状態を確認する必要があり、従来は、その確認が困難なため、バリ除去作業そのものが殆んど行われていなかった。 That is, in the conventional case, since the fitting groove 29 opens toward the inside of the concave groove 26, the mounting operation of the airtight member 30 must be performed within the concave groove 26. Not only is the degree of freedom of manual work constrained, but also the position of the opening of the fitting groove 29 is checked, and the work of attaching the airtight member 30 to the fitting groove 29 is very inefficient. there were.
In particular, the burr removal operation requires confirmation of the state of the burr. Conventionally, since such confirmation is difficult, the burr removal operation itself has hardly been performed.

然るに、本発明は、嵌合溝１６を、前記のようにその溝中心軸線Ｌ１を、凹溝内側から凹溝１４の開口外側に向けて傾斜して延びるような形態としたために、嵌合溝１６の開口部１６ｂを、凹溝１４の外方から容易に視認することができるとともに、気密部材１５の取付作業も、凹溝１４の外方から行うことができるため、その作業効率は極めて良好となる。 However, according to the present invention, since the fitting groove 16 is configured so that the groove center axis L1 extends obliquely from the inner side of the concave groove toward the outer side of the opening of the concave groove 14 as described above, the fitting groove 16 is provided. The opening 16b of 16 can be easily seen from the outside of the groove 14 and the work of attaching the airtight member 15 can also be performed from the outside of the groove 14, so that the work efficiency is very good. It becomes.

また、バリ発生の状態も、凹溝１４の外方から容易に確認することができるため、バリの除去作業も簡単に行うことができる。バリの除去により、窓框１０における横框材と縦框材が当接する角部において、これらの框材の両嵌合溝に亘って、気密部材１５を連続して取付けることが可能となり、従来は行われていなかった窓框の角部における気密性を向上させることができる。 Further, since the state of burrs can be easily confirmed from the outside of the concave groove 14, the burrs can be removed easily. By removing the burr, it becomes possible to continuously attach the airtight member 15 across the fitting grooves of these saddle members at the corners where the horizontal saddle member and the vertical saddle member come into contact with each other. Can improve the airtightness at the corner of the window sill that has not been done.

嵌合溝１６は、その開口部１６ｂの開口幅よりも奥部が幅広なものとして、窓框１０を構成する框材の長手方向に沿って設けられている。 The fitting groove 16 is provided along the longitudinal direction of the glazing material that constitutes the window ledge 10 on the assumption that the depth is wider than the opening width of the opening 16b.

嵌合溝１６の開口部１６ｂは、開口部１６ｂより奥部の幅広溝の両側前端縁から係止片１６ｃを相互に近接するように延設し、両係止片１６ｃの端縁間を開口部１６ｂとすることにより、開口部１６ｂの開口幅よりも奥部が幅広な溝となるように形成されている。
両係止片１６ｃは、嵌合溝１６の溝底１６ａから開口部１６ｂに至る溝中心軸線Ｌ１とほぼ直交する平面１６ｄ上に位置している。 The opening 16b of the fitting groove 16 extends from the front end edges on both sides of the wide groove deeper than the opening 16b so as to be close to each other, and opens between the edges of the both locking pieces 16c. By forming the portion 16b, the groove is formed so that the inner portion is wider than the opening width of the opening portion 16b.
Both locking pieces 16c are located on a plane 16d that is substantially orthogonal to the groove center axis L1 extending from the groove bottom 16a of the fitting groove 16 to the opening 16b.

嵌合溝１６には、モヘヤ、ゴム、ビード、エラストマ等によって製造された気密部材１５が嵌合されている。この気密部材１５は、框材の長手方向に延びる閉塞部１５ａと、この閉塞部１５ａにおける室内外方向の一端に設けた、係止爪１５ｂを有する取付部１５ｃと、他端に設けた弾性変形可能な当接部１５ｄとを有している。 The fitting groove 16 is fitted with an airtight member 15 made of mohair, rubber, bead, elastomer or the like. The airtight member 15 includes a closing portion 15a extending in the longitudinal direction of the saddle member, an attachment portion 15c having a locking claw 15b provided at one end of the closing portion 15a in the indoor / outdoor direction, and an elastic deformation provided at the other end. A possible contact portion 15d.

取付部１５ｃを窓框１０の奥部を幅広とした嵌合溝１６内に嵌合させて、係止爪１５ｂを嵌合溝１６の開口部１６ｂを形成する係止片１６ｃの端縁に係止させることにより、気密部材１５を窓框１０に取付けるとともに、気密部材１５の弾性変形可能な当接部１５ｄを樹脂製窓枠１の下レール５ｂ、上レール６ａ、嵌入突条７ａの側面５ｅ、６ｃ、７ｂに当接させることにより、窓框１０の凹溝１４内における、凹溝１４を形成する前後壁１７と、樹脂製窓枠１の上下レール等の突条間との隙間の可及的な気密保持を図るようにしてある。 The mounting portion 15c is fitted in the fitting groove 16 having the back part of the window ridge 10 wide, and the locking claw 15b is engaged with the edge of the locking piece 16c forming the opening 16b of the fitting groove 16. By stopping, the airtight member 15 is attached to the window lid 10, and the elastically deformable contact portion 15d of the airtight member 15 is attached to the lower rail 5b, the upper rail 6a, and the side surface 5e of the fitting protrusion 7a. , 6c, 7b, the gap between the front and rear walls 17 forming the recessed groove 14 and the protrusions such as the upper and lower rails of the resin window frame 1 in the recessed groove 14 of the window lamp 10 is allowed. It is intended to keep the airtight as much as possible.

本発明において、特に好ましい気密部材１５の形態は、取付部１５ｃを、閉塞部１５ａにおける室内外方向の一端裏側に設けるとともに、この取付部１５ｃを窓框１０の嵌合溝１６内に嵌合させた状態において、閉塞部１５ａが樹脂製窓枠１の突条である上下レール６ａ、５ｂや、嵌入突条７ａに対してほぼ直交して接近するように閉塞部１５ａを湾曲させた形状としたものである。 In the present invention, a particularly preferable form of the airtight member 15 is that the attachment portion 15c is provided on the back side of one end of the closed portion 15a in the indoor / outdoor direction, and the attachment portion 15c is fitted into the fitting groove 16 of the window jar 10. In this state, the closing portion 15a is curved so that the closing portion 15a approaches the upper and lower rails 6a and 5b, which are the protrusions of the resin window frame 1, and the fitting protrusion 7a. Is.

このような形態の気密部材１５とすることにより、溝底１６ａから開口部１６ｂに至る嵌合溝１６の溝中心軸線Ｌ１を、凹溝内外から凹溝１４の開口外側に向けて傾斜して延びるように位置させた嵌合溝１６内に、気密部材１５の取付部１５ｃを、凹溝１４の外方から容易に嵌合させて取付けることができる。 With the airtight member 15 having such a configuration, the groove center axis L1 of the fitting groove 16 extending from the groove bottom 16a to the opening 16b is inclined and extended from the inside and outside of the groove toward the outside of the groove 14 opening. The fitting portion 15c of the airtight member 15 can be easily fitted and attached from the outside of the concave groove 14 in the fitting groove 16 positioned as described above.

また、閉塞部１５ａが樹脂製窓枠１の突条である上下レール６ａ、５ｂや嵌入突条７ａに対してほぼ直交して接近するように湾曲されているため、凹溝１４の前後壁１７と、突条６ａ、５ｂ、７ａ間の隙間を閉塞する閉塞部１５ａの前後方向の幅がほぼ最小となり、閉塞部１５ａの部分における気密保持が不完全な場合にも、その不完全の程度を抑止して、可及的な気密性の向上を図ることができる。 Further, since the closing portion 15a is curved so as to approach the upper and lower rails 6a and 5b and the fitting protrusion 7a which are the protrusions of the resin window frame 1, the front and rear walls 17 of the concave groove 14 are curved. And the width in the front-rear direction of the closing portion 15a that closes the gap between the ridges 6a, 5b, 7a is almost minimized, and even when the airtightness holding in the portion of the closing portion 15a is incomplete, the degree of incompleteness is reduced. It can be suppressed and the airtightness can be improved as much as possible.

さらに、前記のように閉塞部１５ａが樹脂製窓枠１の突条６ａ、５ｂ、７ａに対してほぼ直交して接近しているため、気密部材１５の当接部１５ｄの突条６ａ、５ｂ、７ａに対する当接力を大きくすることができるとともに、直交していない場合に生じ易い経時的なへたりを極力抑止し、気密部材１５の当接部１５ｄの、突条６ａ、５ｂ、７ａに対する当接力を長期間に亘って保持することができる。 Further, as described above, since the closing portion 15a is approaching substantially orthogonal to the protrusions 6a, 5b, 7a of the resin window frame 1, the protrusions 6a, 5b of the contact portion 15d of the airtight member 15 are provided. , 7a can be increased, and the sag that is likely to occur when not orthogonal to each other is suppressed as much as possible, and the contact portion 15d of the airtight member 15 contacts the ridges 6a, 5b, 7a. The contact force can be maintained for a long time.

当接部１５ｄは、上下レール６ａ、５ｂおよび嵌入突条７ａの側面６ｃ、５ｅ、７ｂに当接して、一般には凹溝１４の溝底１４ａ側に弾性的に折り曲げられる。これにより、当接部１５ｄは、上下レール６ａ、５ｂおよび嵌入突条７ａの側面６ｃ、５ｅ、７ｂに弾発的に付勢されるため、優れて良好に樹脂製窓枠１と窓框１０との間の気密性の向上を図ることができる。 The contact portion 15d contacts the upper and lower rails 6a, 5b and the side surfaces 6c, 5e, 7b of the fitting protrusion 7a, and is generally elastically bent toward the groove bottom 14a side of the groove 14. As a result, the contact portion 15d is elastically biased to the upper and lower rails 6a, 5b and the side surfaces 6c, 5e, 7b of the fitting protrusion 7a. The airtightness between the two can be improved.

以上説明したように、本発明は、外周端面に凹溝が設けられた窓框と、前記凹溝内に嵌入しうる、樹脂製窓枠に設けられた障子用の上下レール、または樹脂製窓枠の縦枠に設けられた嵌入突条などの樹脂製窓枠の突条との間の間隙の気密性の向上を図る気密部材の取付形態及びその気密部材に関し、その効果を要約すると下記の通りである。すなわち、

３)バリの除去により、窓框における横框材と縦框材とが当接する角部において、前記横框材と縦框材の両嵌合溝に亘って、気密部材を連続して取付けることが可能となり、この角部における気密性の向上を図ることができる。
４)本発明の気密構造に使用する好ましい形態の気密部材は、窓框への取付作業を効率よく実施することができるとともに、気密性に優れ、かつ長期に亘って経時的な気密性の低下を防止することができる。 As described above, the present invention includes a window rod having a groove on the outer peripheral end surface, and a top and bottom rail for a shoji that can be fitted into the groove and provided on a resin window frame, or a resin window. The following is a summary of the effects of the airtight member mounting form for improving the airtightness of the gap between the protrusions of the resin window frame such as the insertion protrusions provided in the vertical frame of the frame and the airtight member thereof.
