Description

本発明は、ガラスパネルを保持するガラス保持金具を備える障子に関する。 The present invention relates to a shoji screen provided with a glass holding metal fitting for holding a glass panel.

従来、框体と、框体の内側に配置されるガラスパネルと、框体の内部に配置されガラスパネルの端部を保持するガラス保持金具と、を備える障子が知られている（例えば、特許文献１参照）。特許文献１に記載のガラス保持金具は、ガラスパネル側が開放する断面視略Ｕ字形状に形成されている。 Conventionally, a shoji having a stile, a glass panel arranged inside the stile, and a glass holding metal fitting arranged inside the stile and holding an end portion of the glass panel is known (for example, a patent). Reference 1). The glass holding metal fitting described in Patent Document 1 is formed in a substantially U-shaped cross-sectional view in which the glass panel side is open.

框体の下框においてガラスパネルの下方に配置される断面視略Ｕ字形状のガラス保持金具は、下方から支持される構造である。ここで、ガラス保持金具を支持する部材が樹脂框部材で形成される場合には、火災発生時に樹脂框部材が溶融すると、ガラス保持金具の支持が外れ、ガラスパネルが下方に下がったり傾いてしまうおそれがある。ガラスパネルが下方に下がったり傾くと、ガラスパネルと框体との間に隙間が形成されたり、ガラスパネルが框体から落下するおそれがある。そのため、火災発生時に、下方に下がったり傾いたりすることを抑制した状態でガラスパネルを支持できることが望まれている。 The glass holding metal fitting having a substantially U-shaped cross section, which is arranged below the glass panel in the lower frame of the frame body, has a structure supported from below. Here, when the member supporting the glass holding metal fitting is formed of the resin stile member, if the resin stile member melts in the event of a fire, the support of the glass holding metal fitting is disengaged and the glass panel is lowered or tilted. There is a risk. If the glass panel is lowered or tilted, a gap may be formed between the glass panel and the frame, or the glass panel may fall from the frame. Therefore, it is desired that the glass panel can be supported in a state where it is suppressed from being lowered or tilted in the event of a fire.

本発明は、火災発生時に、ガラスパネルが下がったり傾いたりすることを抑制した状態でガラスパネルを支持可能な障子を提供することを目的とする。 An object of the present invention is to provide a shoji that can support a glass panel in a state where the glass panel is prevented from being lowered or tilted in the event of a fire.

The glass holding metal fittings are an intermediate horizontal plate portion extending in the prospective direction, an upper piece extending upward from the indoor side end portion of the intermediate horizontal plate portion, and a lower portion extending downward from the outdoor outer end portion of the intermediate horizontal plate portion. With respect to the shoji with a piece.

However, the present invention is not limited to this, and the lower stile side end joint fitting 428 and the tapping screw fastening portion 426 may be configured to be directly fixed to the outer stile 43.

本実施形態によれば、以下の効果が奏される。 According to this embodiment, the following effects are achieved.

本実施形態の内障子３及び外障子４は、枠組みされた框体３５，４５と、框体３５，４５の内側に配置されたガラスパネル３６，４６と、框体３５，４５の下框３２，４２に配置されガラスパネル３６，４６の下端を保持する段差状ガラス保持金具６と、備え、段差状ガラス保持金具６は、見込方向に延びる中間横板部６１と、中間横板部６１の室内側の端部から上方に延びる上方延出片６２と、中間横板部６１の室外側の端部から下方に延びる下方延出片６３と、を有する。これにより、段差状ガラス保持金具６の下方延出片６３により下方側から支持可能であるため、火災発生時に、ガラスパネル３６，４６が下方に下がったり傾いたりすることを抑制した状態で、ガラスパネル３６，４６を支持できる。 The inner sash 3 and the outer sash 4 of the present embodiment include the framed stiles 35 and 45, the glass panels 36 and 46 arranged inside the stiles 35 and 45, and the lower stile 32 of the stiles 35 and 45. , 42 is provided with a stepped glass holding metal fitting 6 for holding the lower ends of the glass panels 36 and 46, and the stepped glass holding metal fitting 6 includes an intermediate horizontal plate portion 61 extending in the prospective direction and an intermediate horizontal plate portion 61. It has an upward extending piece 62 extending upward from the end on the indoor side, and a downward extending piece 63 extending downward from the outdoor end of the intermediate horizontal plate portion 61. As a result, the glass can be supported from the lower side by the downward extending piece 63 of the stepped glass holding metal fitting 6, so that the glass panels 36 and 46 are prevented from being lowered or tilted in the event of a fire. Can support panels 36, 46.

また、本実施形態においては、下方延出片６３は、中間横板部６１の室外側の端部から外側に向かって斜め下方に傾斜して形成される。そのため、下框３２，４２のガラス溝３５１，４５１に段差状ガラス保持金具６を配置する場合に、斜め下方に傾斜する下方延出片６３により段差状ガラス保持金具６の幅方向の端部の位置決めがしやすく、段差状ガラス保持金具６を下框３２，４２のガラス溝３５１，４５１の幅の範囲に納めやすい。よって、段差状ガラス保持金具６を下框３２，４２に容易に配置できる。 Further, in the present embodiment, the downward extending piece 63 is formed so as to be inclined diagonally downward from the outdoor end of the intermediate horizontal plate portion 61 toward the outside. Therefore, when the stepped glass holding metal fitting 6 is arranged in the glass grooves 351 and 451 of the lower stiles 32 and 42, the end portion of the stepped glass holding metal fitting 6 in the width direction is formed by the downward extending piece 63 that is inclined diagonally downward. It is easy to position, and it is easy to fit the stepped glass holding metal fitting 6 within the width range of the glass grooves 351 and 451 of the lower stiles 32 and 42. Therefore, the stepped glass holding metal fitting 6 can be easily arranged on the lower stiles 32 and 42.

また、本実施形態においては、下方延出片６３は、下框３２，４２の長手方向に亘って配置される。これにより、下方延出片６３は、下框３２，４２の長手方向に亘って、段差状ガラス保持金具６を下方側から支持できる。また、火災発生時に、下方延出片６３は、下框３２，４２の長手方向に亘って、火炎を遮ることができるとともに、火炎が見えないように隠すことができる。 Further, in the present embodiment, the downward extending piece 63 is arranged along the longitudinal direction of the lower stiles 32 and 42. As a result, the downward extending piece 63 can support the stepped glass holding metal fitting 6 from the lower side over the longitudinal direction of the lower stiles 32 and 42. Further, in the event of a fire, the downward extending piece 63 can block the flame in the longitudinal direction of the lower stiles 32 and 42, and can hide the flame so that it cannot be seen.

また、本実施形態においては、下框３２，４２に形成されたタッピングネジ締結部３２６，４２６は、段差状ガラス保持金具６の下方に配置され、段差状ガラス保持金具６を支持する。これにより、段差状ガラス保持金具６は、下方側から、下方延出片６３及びタッピングネジ締結部３２６，４２６の２箇所において支持される。よって、段差状ガラス保持金具６を下方側から２箇所において支持できるため、例えば火災発生時においても、ガラスパネル３６，４６を保持する段差状ガラス保持金具６が傾くことを一層抑制できる。 Further, in the present embodiment, the tapping screw fastening portions 326 and 426 formed on the lower stiles 32 and 42 are arranged below the stepped glass holding metal fitting 6 and support the stepped glass holding metal fitting 6. As a result, the stepped glass holding metal fitting 6 is supported from the lower side at two positions, the downward extending piece 63 and the tapping screw fastening portions 326 and 426. Therefore, since the stepped glass holding metal fitting 6 can be supported at two places from the lower side, for example, even in the event of a fire, the stepped glass holding metal fitting 6 holding the glass panels 36, 46 can be further suppressed from tilting.
