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。 TECHNICAL FIELD The present invention relates to a shoji screen equipped with a glass holding 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, shoji screens have been known that include a frame, a glass panel placed inside the frame, and glass holding fittings placed inside the frame to hold the ends of the glass panel (for example, as disclosed in patents (See Reference 1). The glass holding fitting described in Patent Document 1 is formed into a substantially U-shape in cross section with the glass panel side open.

特開2014-156732号公報Japanese Patent Application Publication No. 2014-156732

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。 A glass holding fitting having a substantially U-shape in cross section and arranged below the glass panel in the lower stile of the frame has a structure that is supported from below. If the member supporting the glass holding fittings is made of a resin frame member, if the resin frame member melts in the event of a fire, the glass holding fittings will become unsupported and the glass panel will fall or tilt. There is a risk. If the glass panel falls downward or tilts, 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 to be able to support the glass panel in a state where it is suppressed from falling or tilting 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。 SUMMARY OF THE INVENTION An object of the present invention is to provide a shoji that can support a glass panel while suppressing the glass panel from lowering or tilting in the event of a fire.

A cap 407 is attached to the hole 43b formed in the outer frame 43.

なお、本実施形態においては、下框側端部仕口金具428及びタッピングネジ締結部426を、召外框43の内部に配置された召外框芯材437(図7参照)に固定するように構成したが、これに限定されず、下框側端部仕口金具428及びタッピングネジ締結部426を、召外框43に直接固定するように構成してもよい。 In addition, in this embodiment, the lower stile side end fitting 428 and the tapping screw fastening part 426 are fixed to the outer stile core material 437 (see FIG. 7) arranged inside the outer stile 43. However, the configuration is not limited thereto, and the lower stile side end 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 shoji 3 and the outer shoji 4 of this embodiment include framed frames 35, 45, glass panels 36, 46 arranged inside the frames 35, 45, and a lower stile 32 of the frames 35, 45. , 42 to hold the lower ends of the glass panels 36, 46; It has an upwardly extending piece 62 extending upwardly from the indoor side end, and a downwardly extending piece 63 extending downwardly from the indoor side end of the intermediate horizontal plate portion 61. As a result, since the step-like glass holding fitting 6 can be supported from below by the downwardly extending piece 63, the glass panels 36, 46 can be prevented from falling or tilting in the event of a fire. Panels 36, 46 can be supported.

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 this embodiment, the downwardly 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 placing the step-shaped glass holding fitting 6 in the glass grooves 351, 451 of the lower frames 32, 42, the downwardly extending piece 63 that slopes diagonally downward allows the edge of the stepped glass holding fitting 6 in the width direction to be fixed. Positioning is easy, and the stepped glass holding fitting 6 can be easily accommodated within the width range of the glass grooves 351, 451 of the lower frames 32, 42. Therefore, the step-shaped glass holding fitting 6 can be easily arranged on the lower stile 32, 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。 Moreover, in this embodiment, the downwardly extending piece 63 is arranged over the longitudinal direction of the lower stile 32,42. Thereby, the downwardly extending piece 63 can support the stepped glass holding fitting 6 from below over the longitudinal direction of the lower stile 32, 42. Further, when a fire occurs, the downwardly extending piece 63 can block the flames in the longitudinal direction of the lower frames 32, 42, and can hide the flames so that they 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 this embodiment, the tapping screw fastening parts 326 and 426 formed on the lower frames 32 and 42 are arranged below the stepped glass holding fitting 6 and support the stepped glass holding fitting 6. Thereby, the stepped glass holding fitting 6 is supported from the lower side at two locations: the downwardly extending piece 63 and the tapping screw fastening portions 326 and 426. Therefore, since the stepped glass holding fittings 6 can be supported from the lower side at two locations, it is possible to further suppress the stepped glass holding fittings 6 that hold the glass panels 36, 46 from tilting, even in the event of a fire, for example.

以上、本発明の好ましい実施形態について説明したが、本発明は、上述の実施形態に制限されるものではなく、適宜変更が可能である。
