Description

【0001】
【発明の属する技術分野】
本発明は、オフィスビルやマンション等の建築物の開口部に建付けられる扉体の端部連結構造の技術分野に属するものである。
【0002】
【従来の技術】
一般に、建築用の扉体のなかには、表裏一対の面板のあいだにコア材、端部フレームが介装されるものとして、図12に示すように表裏面板1、3の端縁部がそれぞれコ字形に折り返し折曲され、その折曲先端側片2a、3a同志を接触状に対向させるようにして組立てたものがある。
【0003】
【発明が解決しようとする課題】
しかるにこのものは、表裏面板2、3は、コア材4や端部フレーム5に接着固定されるものの、前記接触する折曲先端側片2a、3a同志は単に突き合っているだけで固定されたものではなく、このため、折曲先端側片2a、3aやコア材4、端部フレーム5の寸法誤差や組立て誤差等によって折曲先端側片2a、3a間に隙間ができたとき、扉体開閉時にビビリ音が生じて騒音発生の原因となるうえ、接着力の低下により面板が剥離してしまう惧れもあり、ここに本発明が解決しようとする課題があった。
【0004】
【課題を解決するための手段】
本発明は、上記の如き実情に鑑みこれらの課題を解決することを目的として創作されたものであって、請求項1の発明は、扉体を構成する表裏一対の面板の端縁部を略コ字形に折り返し折曲し、互いに対向する折曲先端側片同志の複数箇所を連結手段を介して一体に連結して扉体の端部連結をするにあたり、前記連結手段は、扉体の凹溝状をした端部フレームの両内壁面間に抜止め状に嵌合する一対の脚片部と、該脚片部から延設される一対の挟持片部とが形成されたものとし、該両挟持片部間に両折曲先端側片を挟持状に嵌合することで構成されることを特徴とする扉体の端部連結構造である。
請求項2の発明は、請求項1において、端部フレームに対する脚片部の抜止めは、該脚片部に外方に向けて切欠き形成した係止爪が端部フレームの脚片に穿設の係止孔部に嵌合係止することで行われるようになっていることを特徴とする扉体の端部連結構造である。
これによって、寸法誤差や組立て精度等の事情で折曲先端側片同志の間に隙間が生じたとしても連結手段により一体に連結されていて、扉体開閉時のビビリ音等の騒音を解消できるうえ、従来の表裏面板が接着剤により接着されているだけのもののように、接着力の低下により面板が剥離してしまうことを防止できる。
【0005】
【発明の実施の形態】
次に、本発明の実施の形態を図面に基づいて説明するが、図1〜図9は本発明を説明す るための参考の実施の形態であり、図10、11に本発明の実施の形態を示す
まず、図1〜図9に示す参考の実施の形態において、1は開口部に建付けられる扉体であって、該扉体1は所定寸法に切断された長方形金属平板で形成される表裏一対の面板2、3と、これら面板2、3間に介装されるコア材4、端部フレーム5等の部材装置により構成されていること等は何れも従来通りの構成となっている。
【0006】
前記表裏面板2、3の左右側縁部は、略コ字形に折り返し折曲されて扉体1の端部側面の先端に折曲先端側片2a、3aが形成されているが、扉体1は、これら折曲先端側片2a、3a同志が互いに対向状に接当された状態で組立てられ、かつこれら表裏面板2、3間には、コア材4および左右端部に位置して端部フレーム5が介装されている。そして、戸先側となる両折曲先端側片2a、3aは、凹溝状の端部フレーム5の凹部内において、上下方向複数箇所が本発明の連結手段により一体に連結されるが、該第一の実施の形態では、連結手段として連結具(本発明の連結手段に相当)6が用いられて両折曲先端側片2a、3aが、上下方向に450mm以下のピッチで設けられて一体に連結されるように構成されている。
【0007】
つまり、連結具6は、弾性を有する板状鋼材を用いて略U字形に折曲されて一対の嵌合片6a、6bが形成されたものなっている。そして、一方の嵌合片6aは、開口側を一方の面板(本実施の形態においては表面板2)の折曲先端側片2a端部から差し込まれて面板側面にリベット6c等の固着具で止着される固定部に構成されており、他方の嵌合片6bは、二股状に分岐し先端側に凹状に陥没した止め部6dが形成されており、該止め部6dと表面板折曲先端側片2aとのあいだに、裏面板3の折曲先端側片3aが外側方からスライド挿入され、これによって両嵌合片6a、6bとのあいだに両折曲先端側片2a、3aが挟持状に嵌合されるようになっている。ここで、止め部6dは裏面板折曲先端側片3aに弾圧状に接当するように設定されていて、両折曲先端側片2a、3aに抜止め状に嵌合されている。
【0008】
一方、吊元側となる折曲先端側片2a、3aは、蝶番7の取付け部位に切欠き2b、3bが形成され、ここに端部フレーム5と両面板2、3端部側面とのあいだに位置して蝶番用スペーサ7aを介装して蝶番7をリベット7b等により止着することで、両折曲先端側片2a、3a同志が一体に連結されるように設定されているが、蝶番7が設けられるスパンは戸先側の連結具6による連結スパンよりも長いものになっているので、蝶番7同志のあいだの適宜箇所に連結スペーサ7cを介装しこれを表裏面板2、3の端部側面にリベット等7bにより止着することで、両折曲先端側片2a、3a同志の一体的な連結がなされる設定となっている。ここで、スペーサ7a、7cをリベット7b止着する場合、リベット頭が表裏面板2、3の端部側面から突出しないよう、該端部側面に穿設の孔2c、3cをポンチ等により皿加工した後、リベット止着されている。さらに、図9に示された連結用スペーサ7dは、図7、8に示した中実状の連結用スペーサ7cと異なり断面略コ字形状に形成されているが、このものでは、連結用スペーサ7dと端部フレーム5とのあいだに隙間が形成されるため、表裏面板2、3の端部側面とのリベット止着が可能になって端部フレーム5に孔加工をする必要がない。
【0009】
叙述の如く構成された参考の実施の形態において、表裏面板2、3は、前述したように、予め表面板2に連結具6の一方の嵌合片6aを止着した後に、裏面板3を表面板2aと他方の嵌合片6bとのあいだに挿入することで組立られることになるが、この場合に、両折曲先端側片2a、3aは、連結具6の両嵌合片6a、6bとのあいだに挟持状に嵌合されることになって、両者が一体に連結されることになる。この結果、寸法誤差や組立て精度等の事情で折曲先端側片2a、3a同志の間に隙間が生じたとしても、これらは連結具6で固定されていることになって、扉体開閉時にビビリ音が生じて騒音発生の原因となってしまうようなことを防止できるうえ、従来の表裏面板が接着剤により接着されているだけのもののように、接着力の低下により面板が剥離してしまうことを防止できる。
【0010】
さらにこのものでは、連結具6は弾性を有する鋼材で形成されているため、両折曲先端側片2a、3aは連結具6により弾圧状に挟持、嵌合されることになって、両折曲先端側片2a、3a同志の一体かがより強固になされることになって、さらに有効な騒音防止効果が計れる。
【0011】
次ぎに、本発明の実施の形態を図10、11に示すが、該図面において、第一の実施の形態と共通するもの(同一のもの)については、同一の符号を付して引き出すと供にその詳細については省略する。尚、図1については参考の実施の形態のものを共用できる。図面において、連結具10は弾性を有する鋼材により端部フレーム5の凹溝形状に沿うよう略コ字形に形成されている。両脚片部10aには外方に向けて切欠かれた係止爪10bが形成されている一方、端部フレーム5の脚片5aには係止孔部5bが穿設されていて、係止爪10bが係止孔部5bに嵌合係止することで両脚片部10aが端部フレーム5の両内壁面間に抜止め状に嵌合されている。そして、両脚片部10aからは一対の挟持片部10cが延出して形成されており、これら挟持片部10cのあいだに両折曲先端側片2a、3aが挟持状に嵌合されるように設定されている。この場合、連結具10は予め端部フレーム5に抜止め状にセットした後、表裏面板2、3の各折曲先端側片2a、3aを順次挟持片部10d間に挿入することで組立られるように設定されており、この場合では、端部フレーム5による連結具10の抜止めがなされることになる。

[0006]
The left and right side edge portions of the front and back plates 2 and 3 are folded back into a substantially U-shape, and bent front end side pieces 2a and 3a are formed at the front end of the side surface of the end portion of the door body 1. Is assembled in a state in which the bent front end side pieces 2a and 3a are in contact with each other so as to face each other, and between the front and back plates 2 and 3, an end portion located at the core material 4 and the left and right end portions A frame 5 is interposed. And both the bending front end side pieces 2a and 3a on the door end side are integrally connected by the connecting means of the present invention at a plurality of positions in the vertical direction in the concave portion of the concave groove end frame 5. In the first embodiment, a connecting tool (corresponding to the connecting means of the present invention) 6 is used as a connecting means, and both bent front end pieces 2a and 3a are provided at a pitch of 450 mm or less in the vertical direction and integrated. It is comprised so that it may be connected with.
[0007]
That is, the connecting tool 6 is bent into a substantially U shape using an elastic plate-shaped steel material to form a pair of fitting pieces 6a and 6b. Then, one fitting piece 6a is inserted from the end of the bent tip side piece 2a of one face plate (surface plate 2 in the present embodiment) on the opening side, and is attached to the side surface of the face plate with a fixing tool such as a rivet 6c. The other fitting piece 6b is formed with a stopper 6d that is bifurcated and recessed at the tip side, and the stopper 6d and the surface plate are bent. Between the front end side piece 2a, the bent front end side piece 3a of the back plate 3 is slid and inserted from the outside, so that both the bent front end side pieces 2a, 3a are inserted between the both fitting pieces 6a, 6b. It is fitted in a pinched form.
