Description
本発明は、引違障子の召合せ部の水密ラインを構成する風止板及び該風止板を備えるサッシに関する。 The present invention relates to a windshield plate that forms a watertight line of a summoning part of a draw shoji and a sash including the windshield plate.
採光や換気等を目的として、建物の開口部にサッシ枠を設け、このサッシ枠に、外障子と内障子とからなる引違障子を取り付けた引違サッシが使用されている。このような引違サッシでは、サッシ枠の下枠と、内障子下部及び外障子下部との間から雨水が室内に浸入することを防止するために、サッシ枠の下枠における内障子と外障子の召し合せ部と対向した位置に、風止板を取り付けたものがある。 For the purpose of daylighting and ventilation, a sash frame is provided at the opening of a building, and a sash frame is used in which a sash frame composed of an external shoji and an internal sash is attached. In such a pulling sash, in order to prevent rainwater from entering the room between the lower frame of the sash frame and the lower part of the inner and outer shojis, There is one with a windshield attached at a position facing the summoning section.
例えば特開平９−２４２２３号公報（特許文献１）には、サッシ枠の下枠の突出横板の長手方向中間部に形成された取付開口部及び切欠部に嵌合させて風止板を取り付けることにより、サッシ枠の下枠と、内障子下部及び外障子下部との間から雨水が室内に浸入することを防止することが記載されている（例えば段落〔０００１〕、〔００３２〕及び図８）。 For example, in Japanese Patent Application Laid-Open No. 9-24223 (Patent Document 1), a windshield plate is attached by fitting into a mounting opening and a notch formed in a longitudinal intermediate portion of a protruding horizontal plate of a lower frame of a sash frame. Thus, it is described that rainwater is prevented from entering the room from between the lower frame of the sash frame and the lower part of the inner shoji and the lower part of the outer shoji (for example, paragraphs [0001], [0032] and FIG. 8). ).
特許文献１の風止板では、風止板を取り付けるための取付開口部及び切欠部を形成しなければならず、サッシ枠の下枠の加工に必要な工数が増加し、加工が複雑になる。また、取付開口部及び切欠部は、上面と下面とを貫通するように、サッシ枠の下枠に形成されている。そのため、取付開口部及び切欠部と風止板との隙間に浸入した雨水は、室内にまで浸入する可能性があり、引違障子の召合せ部における水密性を十分に確保することができていない。 In the windshield plate of Patent Document 1, it is necessary to form a mounting opening and a notch for attaching the windshield plate, increasing the man-hours required for machining the lower frame of the sash frame, and making the machining complicated. . The attachment opening and the cutout are formed in the lower frame of the sash frame so as to penetrate the upper surface and the lower surface. For this reason, rainwater that has entered the gap between the mounting opening and the notch and the windshield may enter the room, and the watertightness at the summoning part of the sliding door cannot be secured sufficiently. .
また近年では、火災が発生した場合にも閉塞状態を維持して火炎を貫通させない防火性能がサッシに求められている。しかしながら、特許文献１に記載の従来の風止板では、取付開口部及び切欠部と風止板との隙間から火炎が室内に到達するため、要求される防火性能を達成することができていない。 In recent years, a sash is required to have a fireproof performance that keeps the closed state and prevents the flame from penetrating even in the event of a fire. However, in the conventional windshield described in Patent Document 1, the flame reaches the room from the gap between the mounting opening and the notch and the windshield, so that the required fire prevention performance cannot be achieved. .
本発明は、上記の課題を解決すべくなされたものであり、サッシ枠の下枠の加工における工数の増加及び複雑化を抑制でき、かつ、引違障子の召合せ部における水密性を十分に確保でき、しかも、サッシの防火性能を向上させることができる風止板を提供することを目的とする。 The present invention has been made to solve the above-described problems, and can suppress an increase in man-hours and complications in the processing of the lower frame of the sash frame, and sufficiently ensure water-tightness at the summoning part of the sliding shoji. Another object of the present invention is to provide a windshield plate that can improve the fireproof performance of the sash.
上記課題を解決するための本発明の風止板は、サッシ枠と、引違障子の召合せ部の端部との間に配置される風止板であって、前記サッシ枠に設けられ、且つ、気密材を取り付ける取付部に、スライドさせるガイド片を有する、ことを特徴とするものである。 The windshield plate of the present invention for solving the above problems is a windshield plate disposed between a sash frame and an end of the summing part of the sliding shoji, provided on the sash frame, and The mounting portion to which the airtight material is attached has a guide piece to be slid.
本発明の風止板においては、前記ガイド片は、前記取付部に係止する係止部が設けられた弾性片を備えるものであることが好ましい。この場合、係止部は、突起であることが好ましい。さらにこの場合には、前記弾性片は、前記ガイド片の先端側から片持ちに設けられていることが好ましい。 In the windshield plate of this invention, it is preferable that the said guide piece is provided with the elastic piece provided with the latching | locking part latched to the said attaching part. In this case, the locking portion is preferably a protrusion. Furthermore, in this case, it is preferable that the elastic piece is provided in a cantilevered manner from the distal end side of the guide piece.
また本発明の風止板においては、風止板には、加熱発泡材が取り付けられていることが好ましい。 Moreover, in the windshield of this invention, it is preferable that the heating foam material is attached to the windshield.
本発明のサッシは、本発明の風止板と、サッシ枠と、前記サッシ枠に建て込まれた外障子と内障子の少なくとも１つの引違障子とを備える、ことを特徴とするものである。 The sash of the present invention is characterized by comprising the windshield plate of the present invention, a sash frame, and at least one collapsible child of a shoji and an inner pouch built in the sash frame.
本発明によれば、サッシ枠の下枠の加工における工数の増加及び複雑化を抑制でき、かつ、引違障子の召合せ部における水密性を十分に確保でき、しかも、サッシの防火性能を向上させることができる風止板を提供することができる。 According to the present invention, it is possible to suppress the increase in man-hours and complications in the processing of the lower frame of the sash frame, and to sufficiently ensure the water tightness in the summoning part of the sliding shoji, and to improve the fireproof performance of the sash.

以下、本実施形態の風止板４の作用効果について説明する。 Hereinafter, the effect of the windshield 4 of this embodiment is demonstrated.
本実施形態の風止板４は、外障子５に当接する外側気密材が取り付けられた取付部２２及びこの取付部２２に形成された水抜き用の切り欠き部２５を利用して取り付けることができる。そのため、風止板４を取り付ける際に、風止板を取り付けるために従来のように取付開口部及び切欠部を別に形成する必要がない。そのため、サッシ枠の下枠の加工における工数が増加することはなく、複雑化することもない。また、風止板を取り付けるための取付開口部及び切欠部が形成されないため、これらの隙間を経由して雨水や火炎が室内に到達することがない。

The windshield plate 4 of this embodiment is attached using the attachment part 22 to which the outer airtight material which contact | abuts with the shingles 5 is attached, and the notch part 25 for draining formed in this attachment part 22. FIG. it can. Therefore, when the windshield plate 4 is attached, there is no need to separately form an attachment opening and a notch portion as in the prior art in order to attach the windshield plate. Therefore, the man-hour for processing the lower frame of the sash frame does not increase, and it does not become complicated. Moreover, since the attachment opening part and notch part for attaching a windshield board are not formed, rainwater and a flame do not reach a room | chamber interior via these clearance gaps.
As described above, according to the windshield 4 of the present embodiment, it is possible to suppress an increase in man-hours and complications in the processing of the lower frame of the sash frame, and sufficiently secure water tightness in the summoning part of the sliding shoji. Moreover, the fireproof performance of the sash can be improved.
本発明にあっては、一実施形態に示すように、ガイド片４５は、取付部２２を構成する保持用縦板２４ｂに係止する係止部４８ａが設けられた弾性片４８を備えることが好ましい。この構成によれば、係止部４８ａによる係止により、取り付けられた風止板４が取付部２２を構成する保持用縦板２４ｂに対して変位することが規制されて、風止板４が取付部２２を構成する保持用縦板２４ｂから脱落することを抑制することができる。また、係止部４８ａは弾性片４８に設けられているため、風止板４を取り付ける際に、係止部４８ａにより、取り付けの抵抗となる力が発生することを抑制することができる。そのため、風止板４の取り付けの容易性を維持しつつ、風止板４の脱落を抑制することができる。 In the present invention, as shown in one embodiment, the guide piece 45 includes an elastic piece 48 provided with a locking portion 48a that is locked to the holding vertical plate 24b constituting the mounting portion 22. preferable. According to this configuration, due to the locking by the locking portion 48 a, the attached windshield plate 4 is restricted from being displaced with respect to the holding vertical plate 24 b constituting the mounting portion 22, and the windscreen plate 4 is It can suppress falling off from the holding | maintenance vertical board 24b which comprises the attaching part 22. FIG. Moreover, since the latching | locking part 48a is provided in the elastic piece 48, when attaching the windshield plate 4, it can suppress that the force used as resistance of attachment generate | occur | produces by the latching | locking part 48a. Therefore, falling off of the windshield plate 4 can be suppressed while maintaining the ease of attachment of the windshield plate 4.
本発明にあっては、一実施形態に示すように、係止部４８ａは、突起であることが好ましい。この構成によれば、係止部４８ａを簡単な構成とすることができるだけでなく、取付部２２を構成する保持用縦板２４ｂに孔または凹部を設けるのみで風止板４を取り付ける際の風止板４の位置決めが可能となり、かつ、風止板４を取り付ける際に抵抗となる力が発生することをより抑制することができる。 In the present invention, as shown in one embodiment, the locking portion 48a is preferably a protrusion. According to this configuration, not only the locking portion 48a can be made simple, but also the wind when the windshield plate 4 is attached only by providing a hole or a recess in the holding vertical plate 24b constituting the attachment portion 22. The positioning of the stop plate 4 is possible, and it is possible to further suppress the generation of a resistance force when the wind stop plate 4 is attached.
本発明にあっては、一実施形態に示すように、弾性片４８は、ガイド片４５の先端側である他端側から片持ちに設けられていることが好ましい。この構成によれば、風止板４を取り付ける際に大きな力が風止板４に加えられても、片持ち構造により弾性片４８に設けられた係止部に加わる力は低減される。また、係止部（突起）４８ａが弾性片４８の板状部４７側である端部側（他方の端部側）に設けられているので、風止板４のスライドが初期の段階で係止部４８ａが抵抗になることがなく、スライドが終了する段階で貫通孔２４ｅに係止する。よって、弾性片４８の片持ち部（根元）に過度な力が加わらないので、風止板４の取り付け時に弾性片４８及び係止部４８ａが破損することを抑制することができる。 In the present invention, as shown in one embodiment, the elastic piece 48 is preferably provided in a cantilevered manner from the other end side that is the tip side of the guide piece 45. According to this configuration, even when a large force is applied to the windshield plate 4 when the windshield plate 4 is attached, the force applied to the locking portion provided on the elastic piece 48 by the cantilever structure is reduced. Further, since the locking portion (projection) 48a is provided on the end portion side (the other end portion side) which is the plate-like portion 47 side of the elastic piece 48, the sliding of the windshield plate 4 is engaged at the initial stage. The stop portion 48a does not become a resistance, and engages with the through hole 24e when the slide is completed. Therefore, since an excessive force is not applied to the cantilever portion (root) of the elastic piece 48, it is possible to prevent the elastic piece 48 and the locking portion 48 a from being damaged when the windshield plate 4 is attached.
本発明にあっては、一実施形態に示すように、防火性能がサッシに求められる場合に、風止板４には、加熱発泡材が取り付けられていることが好ましい。この構成によれば、火災により風止板４が溶融等して失われた場合でも、加熱発泡材による発泡により、火災が室内に到達することを抑制することができる。特に、図１乃至図７の一実施形態に示すように、風止板４の載置部４６の下面４６ａ及び載置部４６の第２の側面４６ｄに設けることにより、火災が室内に到達する経路に加熱発泡材を発泡させることができ、火災が室内に到達することをより抑制することができる。具体的には、加熱発泡材４３が下枠２ｂの突出横板２３と内下レール１８の室外面に面しているので、アルミニウム合金製の下枠が火炎により高温に上昇した熱を感知し易く、加熱発泡材４３を早期に発泡させることができる。 In the present invention, as shown in one embodiment, when the fireproof performance is required for a sash, it is preferable that a heating foam material is attached to the windshield plate 4. According to this configuration, even when the windshield plate 4 is lost due to melting or the like due to a fire, it is possible to prevent the fire from reaching the room due to foaming by the heating foam material. In particular, as shown in one embodiment of FIGS. 1 to 7, the fire reaches the room by being provided on the lower surface 46 a of the mounting portion 46 and the second side surface 46 d of the mounting portion 46 of the windshield plate 4. The heated foam material can be caused to foam in the path, and the fire can be further suppressed from reaching the room. Specifically, since the heating foam 43 faces the projecting horizontal plate 23 of the lower frame 2b and the outdoor surface of the inner and lower rail 18, the lower frame made of aluminum alloy senses the heat raised to a high temperature by the flame. It is easy to foam the heated foam material 43 at an early stage.
