Description

本発明は、断熱効果が高く、開閉操作も容易な折畳み扉装置に関する。   The present invention relates to a folding door device that has a high heat insulating effect and is easy to open and close.

一般に、折畳み扉装置は複数の扉体を継手框を介して回動自在に連結し、建物開口部の上部レールに吊設することによって構成される。扉体には手掛けが設けられ、上記手掛けを屋外又は屋内側に押し引きすることで折畳み扉を開閉することができる。閉扉時には全ての扉体が面一状に並び、開扉時には扉体が折畳み状態となる。   In general, the folding door device is configured by connecting a plurality of door bodies through a joint rod so as to be rotatable and suspending them from an upper rail of a building opening. A handle is provided on the door body, and the folding door can be opened and closed by pushing and pulling the handle toward the outside or the indoor side. When the door is closed, all the door bodies are arranged flush with each other, and when the door is opened, the door body is folded.

ところで、省エネ、結露防止などの点から、通常の引き戸などは金属と合成樹脂の複合材によって構成し、閉止時に屋外に面する部位を金属とし、屋内に面する部位を合成樹脂として構成する傾向が強くなっている。これに伴い、折畳み扉も金属と合成樹脂の複合構成とすることが望まれている。   By the way, from the viewpoint of energy saving and prevention of dew condensation, ordinary sliding doors, etc. are composed of a composite material of metal and synthetic resin, and the part that faces outdoors when closed is made of metal, and the part that faces indoors is made of synthetic resin Is getting stronger. In connection with this, it is desired that the folding door also has a composite structure of metal and synthetic resin.

しかし、折畳み扉は引き戸とは異なり、扉体が独立しているわけではないので、金属と合成樹脂との複合化を図るため単に屋内側に合成樹脂製カバーを配しても操作性が損なわれる、などの折畳み扉には特有の問題がある。   However, unlike sliding doors, folding doors do not have independent doors, so operability is lost even if a synthetic resin cover is simply placed on the indoor side to make a composite of metal and synthetic resin. There are special problems with folding doors.

本発明は上記問題点を解消し、断熱性に優れるとともに、操作性も良好な折畳み扉装置を提供することをその課題とする。   An object of the present invention is to solve the above-mentioned problems and to provide a folding door device that has excellent heat insulation and good operability.

前記課題を解決するため、本発明に係る折畳み扉装置は、２つの扉体の各一方の縦框を継手框で回動自在に連結し、上記扉体のうちいずれか一方の扉体の他方の縦框を建物躯体に設けた扉枠の開閉方向に移動可能に設けられた突合せ框に回動自在に連結し、開扉時には上記扉体を折り畳むように構成した折畳み扉装置において、閉扉時に屋内側に面する部位を合成樹脂製のカバーで被覆し、継手框と扉体とを、一方の縦框の長手方向に沿って設けた軸状部を他方の長手方向に沿って設けた軸受け溝の内側に回動自在に係合させることによって連結し、上記継手框の屋内側には上記連結部を隠蔽する張り出し部を形成するとともに、閉扉状態において屋内側に面する部位のうち上記軸状部からは合成樹脂製カバーを除いたことを特徴とする。   In order to solve the above-mentioned problem, the folding door device according to the present invention is configured such that each of the vertical rods of the two door bodies is rotatably connected by a joint rod, and the other of the door bodies is one of the door bodies. In a folding door device that is configured to be pivotally connected to a butting rod that is movable in the opening and closing direction of the door frame provided in the building frame, and is configured to fold the door body when the door is opened, A bearing in which a portion facing the indoor side is covered with a cover made of synthetic resin, and a shaft portion provided with a joint rod and a door body along the longitudinal direction of one longitudinal rod is provided along the other longitudinal direction. The shaft is connected to the inside of the groove by being freely pivoted, and an overhanging portion for concealing the connecting portion is formed on the indoor side of the joint rod. The synthetic resin cover is removed from the shape portion.

なお、前記扉体の内側にはガラスが装着され、ガラスの屋内側の周縁部を金属製の押し縁で固定するとともに、押し縁の屋内側に合成樹脂製のカバーを被覆させるのが好ましい。   In addition, it is preferable that glass is attached to the inside of the door body, and the peripheral portion on the indoor side of the glass is fixed with a metal pressing edge, and a cover made of synthetic resin is covered on the indoor side of the pressing edge.

請求項１に係る発明によれば、閉扉状態において、屋内側に面する金属部には合成樹脂製のカバーが被覆されているので、屋内外は断熱され、熱のロスが少なく、また屋内側に結露が生じにくくなるから、カビの発生が防止される。   According to the first aspect of the present invention, in the closed state, the metal part facing the indoor side is covered with the synthetic resin cover, so that the indoor and outdoor are thermally insulated, the heat loss is small, and the indoor side Condensation is less likely to occur, and mold is prevented from being generated.

閉扉状態において屋内側に面する部位のうち上記軸状部からは合成樹脂製カバーは除かれているので、扉体の折畳みと展開を円滑に行なうことができる。なお、軸状部上に結露が生じたとしても、軸状部は折畳み、展開時に軸受け溝を摺動するので、回動により結露は容易に流れ落ちて排水されるから、カビが発生するおそれはない。   Since the synthetic resin cover is removed from the shaft-shaped portion of the portion facing the indoor side in the closed state, the door body can be folded and unfolded smoothly. Even if condensation occurs on the shaft-like part, the shaft-like part will fold and slide in the bearing groove when deployed. Absent.

また、継手框の屋内側には上記連結部を隠蔽する張り出し部が形成されているから、上記軸状部は屋内側からは見えない。したがって、外観が損なわれることがない。   Moreover, since the overhang | projection part which conceals the said connection part is formed in the indoor side of the joint rod, the said axial part cannot be seen from the indoor side. Therefore, the appearance is not impaired.

請求項２に係る発明によれば、扉体のガラスの屋内側周縁部を金属製の押し縁で固定するとともに、押し縁の屋内側に合成樹脂製のカバーを被覆させているから、ガラスを強固に固定することができるとともに、断熱効果も得ることができる。   According to the invention which concerns on Claim 2, while fixing the indoor side peripheral part of the glass of a door body with a metal pushing edge, and covering the synthetic resin cover on the indoor side of a pushing edge, glass is used. While being able to fix firmly, the heat insulation effect can also be acquired.

A shaft portion 15 having a C-shaped cross section is formed at the tip of the projecting edge 14.

扉体８、８は上下框１６、１７と左右の縦框１８とにより方形に框組みされ、内側には二重ガラス２０が装着されている。図５に詳しく示すように、ガラス２０の屋内側の周縁部は金属製の押し縁２１で固定されているとともに、押し縁２１の屋内側は合成樹脂製のカバー２２で被覆されている。扉体８の上下框１６、１７と左右の縦框１８の屋内側に面する部位にも合成樹脂製のカバー２３が被覆されている。   The door bodies 8 and 8 are squarely assembled by upper and lower rods 16 and 17 and left and right vertical rods 18, and a double glass 20 is mounted inside. As shown in detail in FIG. 5, the peripheral portion of the glass 20 on the indoor side is fixed with a metal pressing edge 21, and the indoor side of the pressing edge 21 is covered with a cover 22 made of synthetic resin. Synthetic resin covers 23 are also coated on portions of the door body 8 facing the indoor side of the upper and lower rods 16 and 17 and the left and right vertical rods 18.

また、扉体８の固定框６と突合せ框７に連結される側の縦框１８の長手方向には、上記固定框６又は突合せ框７に形成されたＣ字形の軸状部２４を回動自在に係合する軸受け溝２５が形成されている。   Further, in the longitudinal direction of the vertical rod 18 on the side of the door body 8 connected to the fixed rod 6 and the butting rod 7, the C-shaped shaft portion 24 formed on the fixed rod 6 or the butting rod 7 is rotated. A bearing groove 25 that is freely engaged is formed.

次に、上記２つの扉体８、８は継手框１０を介して連結されている。   Next, the two door bodies 8, 8 are connected via a joint rod 10.

継手框１０の框本体１０ａの屋内側には上記連結部を隠蔽する張り出し部３２が形成され、張り出し部３２の裏側には軸受け溝２６が形成されている。軸受け溝２６は屋外側に開口している。継手框１０の框本体１０ａの屋外側にはT字形の把手３０が突設されている。そして、框本体１０ａの屋内側には合成樹脂製カバー２７が被覆されている。   An overhanging portion 32 for concealing the connecting portion is formed on the indoor side of the rod main body 10 a of the joint rod 10, and a bearing groove 26 is formed on the back side of the overhanging portion 32. The bearing groove 26 is open to the outdoor side. A T-shaped handle 30 protrudes from the outdoor side of the flange main body 10 a of the joint rod 10. A synthetic resin cover 27 is covered on the indoor side of the bag main body 10a.

これに対し、上記扉体８の縦框１８からは延長縁２８が形成され、延長縁２８の端部にはその長手方向に沿って断面Ｃ字形の軸状部２９が形成されている。軸状部２９は上記継手框１０の框本体１０ａに形成された軸受け溝２６の内側に回動可能に係合されている。   On the other hand, an extended edge 28 is formed from the vertical rod 18 of the door body 8, and an end portion of the extended edge 28 is formed with a shaft-shaped portion 29 having a C-shaped cross section along its longitudinal direction. The shaft-shaped portion 29 is rotatably engaged with a bearing groove 26 formed in the flange main body 10a of the joint rod 10.

ところで、図５に示されるように、合成樹脂カバー２３は扉体８の延長縁２８の屋内側に被覆されている。カバー２３は框本体１８ａと延長縁２８にそれぞれ形成された係止溝３３に係止装着されている。その先端の軸状部２９は閉扉状態において屋内側に面するが、回動時には軸受け溝２６の内面に沿って摺動する。
軸状部２９の外面に合成樹脂製カバーを被覆すると、断熱性はよくなるが、円滑に回動させることはできない。そこで、上記軸状部２９からは合成樹脂製カバーを除いている。 Incidentally, as shown in FIG. 5, the synthetic resin cover 23 is covered on the indoor side of the extended edge 28 of the door body 8. The cover 23 is locked and attached to locking grooves 33 formed in the bag main body 18a and the extended edge 28, respectively. The shaft-like portion 29 at the front end faces the indoor side in the closed state, but slides along the inner surface of the bearing groove 26 when rotating.
When the outer surface of the shaft-shaped portion 29 is covered with a synthetic resin cover, the heat insulation is improved, but it cannot be smoothly rotated. Therefore, the synthetic resin cover is removed from the shaft-shaped portion 29.

上記構成において、全ての扉体が展開した閉扉状態において、屋内側に面する金属部には合成樹脂製のカバー１９、２２、２３、２７が被覆されているので、屋内外は断熱され、熱のロスが少なく、また屋内側に結露が生じにくくなるから、カビの発生が防止される。   In the above configuration, in the closed state where all the door bodies are deployed, the metal part facing the indoor side is covered with the synthetic resin covers 19, 22, 23, 27, so that the indoor and outdoor are insulated and heat is applied. The occurrence of mold is prevented because there is little loss of water and condensation is unlikely to occur on the indoor side.

扉枠１の開閉にあたっては、片方の折畳み扉２又は３は２枚の扉体８、８を有し、両側には固定框６と突合せ框７を、中央には継手框１０を有していて、図４のように、両折畳み扉２、３は一方の側のみを折り畳んで開口することもでき、また左右両側へそれぞれ折り畳んで開口することもできる。折畳み扉２、３の形態はこのように２枚の扉体８、８で構成しても、またそれ以上の扉体によって構成してもよく、片側を吊り元框として扉枠１の縦枠に固定する場合もある。   When the door frame 1 is opened and closed, one folding door 2 or 3 has two door bodies 8 and 8, a fixing rod 6 and a butting rod 7 on both sides, and a joint rod 10 in the center. As shown in FIG. 4, the folding doors 2 and 3 can be opened by folding only one side, or can be opened by folding both sides to the left and right. The form of the folding doors 2 and 3 may be constituted by two door bodies 8 and 8 as described above, or may be constituted by more door bodies, and the vertical frame of the door frame 1 with one side as a suspension ridge. It may be fixed to.

なお、折畳み時には折り畳まれた扉体８、８の間には継手框１０の幅分の空間が形成されるから、折畳み時に手や指を挟むことはない。   In addition, since the space for the width | variety of the joint rod 10 is formed between the folded door bodies 8 and 8 at the time of folding, a hand and a finger are not pinched at the time of folding.
