以下、図面を参照しつつ本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明が実施される折戸装置の一例を示しており、図７のＡ−Ａ矢視相当図である。又、図２は該折戸装置の連結部の拡大図である。尚、図中、図７、図８中で示したものと同等のものには同符号を付し、その説明を省略する。   FIG. 1 shows an example of a folding door apparatus in which the present invention is implemented, and is a view corresponding to AA in FIG. FIG. 2 is an enlarged view of the connecting portion of the folding door device. In the figure, the same components as those shown in FIGS. 7 and 8 are denoted by the same reference numerals, and the description thereof is omitted.

扉体１の戸先部分には戸先フレーム１７が設けられ、扉体２の戸尻部分には戸尻フレーム１８が設けられている。該戸先フレーム１７、戸尻フレーム１８はそれぞれ引抜き、或は押出し成形品であり、前記戸先フレーム１７と前記戸尻フレーム１８の断面は左右対称形となっており、蝶番部３の取付け構造は、前記戸先フレーム１７と前記戸尻フレーム１８とで同一となっているので、以下は前記戸先フレーム１７について説明する。   A door-end frame 17 is provided at the door-end portion of the door body 1, and a door-end frame 18 is provided at the door-end portion of the door body 2. The door-end frame 17 and the door-end frame 18 are respectively drawn out or extruded, and the door-end frame 17 and the door-end frame 18 are symmetrical in cross section. Since the door frame 17 and the door bottom frame 18 are the same, the following description will be made on the door frame 17.

図３に示される様に、該戸先フレーム１７の戸先端面には該戸先端面から所定深さ後退した段差面１９が凹設されている。   As shown in FIG. 3, a step surface 19 that is recessed by a predetermined depth from the door front end surface is recessed in the door front end surface of the door end frame 17.

前記蝶番部３は羽片８，９と羽片カバー１１で構成され、前記羽片８は前記扉体１の戸先端面に固着される固定座部８ａと該固定座部８ａから垂直に立上がり、更に平行に屈曲した連結片部８ｂ及び該連結片部８ｂの先端部に形成される連結端８ｃを有している。又、前記羽片９も前記羽片８と同様に固定座部９ａ、連結片部９ｂ、連結端９ｃを有している。前記羽片カバー１１は軸部を有し、前記連結端８ｃ，９ｃを覆うと共に前記軸部が前記連結端８ｃ，９ｃと回転自在に嵌合する様になっている。又、前記連結端８ｃ，９ｃ同士はギア結合している。   The hinge portion 3 is composed of wing pieces 8 and 9 and a wing piece cover 11, and the wing piece 8 is fixed to the door front end surface of the door body 1 and rises vertically from the fixed seat portion 8a. The connecting piece 8b is further bent in parallel and has a connecting end 8c formed at the tip of the connecting piece 8b. Similarly to the wing piece 8, the wing piece 9 has a fixed seat portion 9a, a connecting piece portion 9b, and a connecting end 9c. The wing cover 11 has a shaft portion, covers the connecting ends 8c and 9c, and the shaft portion is rotatably fitted to the connecting ends 8c and 9c. The connecting ends 8c and 9c are gear-coupled.

前記固定座部８ａは、前記段差面１９に嵌合し、段差内に収納される様になっており、又前記固定座部８ａの板厚は前記段差面１９の深さと同一であり、前記固定座部８ａの対向面（上面）と前記戸先フレーム１７の戸先面と面一となっている。又、前記固定座部８ａの上面には突条１３，１４が形成され、前記固定座部８ａの小口と前記突条１４の端面とは面一となっている。   The fixed seat portion 8a is fitted into the stepped surface 19 and is accommodated in the stepped portion, and the plate thickness of the fixed seat portion 8a is the same as the depth of the stepped surface 19, It is flush with the opposing surface (upper surface) of the fixed seat portion 8a and the door-end surface of the door-end frame 17. Further, ridges 13 and 14 are formed on the upper surface of the fixed seat portion 8a, and the edge of the fixed seat portion 8a and the end surface of the ridge portion 14 are flush with each other.

前記固定座部８ａの小口と前記突条１４の端面とを面一とすることで前記固定座部８ａを小さくすることができ（図３、図９参照）材料費が節約できる。   By making the fore end of the fixed seat portion 8a and the end surface of the protrusion 14 flush with each other, the fixed seat portion 8a can be made smaller (see FIGS. 3 and 9), and material costs can be saved.

指詰め防止ゴム１５は、基台部１５ａ及び中空の突出部１５ｂから構成され、前記基台部１５ａは硬質ゴム或は硬質合成樹脂であり、前記突出部１５ｂは軟質ゴム或は軟質合成樹脂等の軟質弾性部材で構成されており、前記基台部１５ａと前記突出部１５ｂは一体成形される。前記突出部１５ｂの断面外形は、対向面が傾斜した４辺形であり、前記突条１３，１４と嵌合する部分は、左右対称形状となっている。この為、前記指詰め防止ゴム１５の断面形状が非対称であっても、隣接する指詰め防止ゴム１５を同一部品とすることができる。   The finger padding prevention rubber 15 includes a base portion 15a and a hollow protruding portion 15b. The base portion 15a is made of hard rubber or hard synthetic resin, and the protruding portion 15b is made of soft rubber or soft synthetic resin. The base portion 15a and the protruding portion 15b are integrally formed. The cross-sectional outer shape of the projecting portion 15b is a quadrilateral whose inclined surface is inclined, and the portions fitted to the ridges 13 and 14 are symmetrical. For this reason, even if the cross-sectional shape of the said finger padding prevention rubber 15 is asymmetrical, the adjacent finger padding prevention rubber 15 can be made into the same component.

前記基台部１５ａは前記突条１３，１４に嵌合し、前記指詰め防止ゴム１５は前記基台部１５ａと前記突条１３，１４との嵌合を介して前記戸先フレーム１７に取付けられる様になっている。   The base portion 15a is fitted to the protrusions 13 and 14, and the finger pad preventing rubber 15 is attached to the door frame 17 through the fitting of the base portion 15a and the protrusions 13 and 14. It is supposed to be.

前記指詰め防止ゴム１５が前記戸先フレーム１７に取付けられた状態では、指詰め防止ゴム１５の反蝶番部３側の幅端部が前記固定座部８ａの端縁から迫出した状態となっており、前記幅端部の底面は、前記固定座部８ａの対向面と前記戸先フレーム１７の戸先端面に掛渡って当接している。従って、前記指詰め防止ゴム１５が前記固定座部８ａの端縁と段差境界線とを覆い、外観上は前記指詰め防止ゴム１５が前記戸先フレーム１７の戸先面に固着された様になっており、前記固定座部８ａの小口は露出しない。   When the finger padding prevention rubber 15 is attached to the door frame 17, the width end of the finger padding prevention rubber 15 on the side opposite to the hinge part 3 protrudes from the edge of the fixed seat 8a. The bottom surface of the width end portion is in contact with the facing surface of the fixed seat portion 8 a and the door front end surface of the door frame 17. Therefore, the finger padding prevention rubber 15 covers the edge of the fixed seat portion 8a and the step boundary line, and the finger padding prevention rubber 15 is fixed to the door end surface of the door end frame 17 in appearance. Thus, the edge of the fixed seat 8a is not exposed.

又、小口は露出せず、前記突出部１５ｂの弾性力によって扉体１との間に間隙が生じるのを防ぐことができるので、塵等がたまる虞れが減少する。   Further, since the forehead is not exposed and it is possible to prevent a gap from being formed between the protrusion 15b and the door body 1 due to the elastic force of the protruding portion 15b, the possibility of accumulation of dust or the like is reduced.

上記した様に、前記指詰め防止ゴム１５は前記突条１３，１４に嵌合することで取付けられるが、開閉により、前記扉体１、扉体２に振動、衝撃が繰返し作用する。この為、前記指詰め防止ゴム１５が下方にズレ落ちることが考えられる。   As described above, the finger pad preventing rubber 15 is attached by being fitted to the ridges 13 and 14, and vibration and impact are repeatedly applied to the door body 1 and door body 2 by opening and closing. For this reason, it is conceivable that the finger filling preventing rubber 15 is displaced downward.

従って、図４に示される様に、前記指詰め防止ゴム１５のズレ防止の為、前記戸先フレーム１７の下端にゴム受け板２１が固着される。   Therefore, as shown in FIG. 4, a rubber backing plate 21 is fixed to the lower end of the door frame 17 in order to prevent the finger padding rubber 15 from shifting.

該ゴム受け板２１は、前記戸先フレーム１７の断面外形と該外形から前記基台部１５ａに相当する部分２１ａが突出した形状となっており、前記基台部１５ａが前記部分２１ａに当接することで、前記指詰め防止ゴム１５の下方への変位を拘束する。   The rubber receiving plate 21 has a cross-sectional outer shape of the door frame 17 and a shape in which a portion 21a corresponding to the base portion 15a protrudes from the outer shape, and the base portion 15a contacts the portion 21a. Thus, the downward displacement of the finger pad preventing rubber 15 is restrained.

尚、前記ゴム受け板２１の材質はズレ防止可能であれば任意であるが、物体や足等が当接しても損傷等を防げる為、ゴムの様な軟質であることが好ましい。又、扉体１の厚さ方向の幅は扉体１の厚さとほぼ同等かそれよりも小さい方が好ましい。更に、受け部材の厚さは、床等に接することがなく扉体１の開閉に支障がない様に薄い方が好ましい。   The material of the rubber receiving plate 21 is arbitrary as long as it can prevent displacement, but is preferably soft like rubber in order to prevent damage or the like even if an object, a foot, or the like comes into contact therewith. The width in the thickness direction of the door body 1 is preferably substantially equal to or smaller than the thickness of the door body 1. Furthermore, it is preferable that the thickness of the receiving member is thin so that it does not contact the floor or the like and does not hinder the opening and closing of the door body 1.

図５は第２の実施例を示している。該第２の実施例では、前記固定座部８ａの小口を延出し、前記指詰め防止ゴム１５の幅端面（図５では上面）と面一とし、前記段差面１９の深さを前記固定座部８ａの板厚より大きくし、前記固定座部８ａ及び前記指詰め防止ゴム１５の端面の一部が段差内に収納される様にしたものである。尚、第２の実施例に於いて、前記段差面１９の深さを前記固定座部８ａの板厚と同一としてもよい。   FIG. 5 shows a second embodiment. In the second embodiment, the small edge of the fixed seat portion 8a is extended to be flush with the width end surface (upper surface in FIG. 5) of the finger padding prevention rubber 15, and the depth of the stepped surface 19 is set to the fixed seat. The thickness is larger than the plate thickness of the portion 8a, and a part of the end face of the fixed seat portion 8a and the finger padding prevention rubber 15 is accommodated in the step. In the second embodiment, the depth of the step surface 19 may be the same as the plate thickness of the fixed seat portion 8a.

該第２の実施例に於いても、前記固定座部８ａの小口は露出せず、外観上は前記指詰め防止ゴム１５が前記戸先フレーム１７の戸先面に固着された様になっている。   Even in the second embodiment, the small edge of the fixed seat portion 8a is not exposed, and the finger padding prevention rubber 15 is fixed to the door-end surface of the door-end frame 17 in appearance. Yes.

図６は、第３の実施例を示している。該第３の実施例では、戸先フレーム１７の戸先端面に段差面１９を凹設せずに、前記指詰め防止ゴム１５の形状を変更することで、前記固定座部８ａの小口を露出させない様にしたものである。   FIG. 6 shows a third embodiment. In the third embodiment, the small edge of the fixed seat portion 8a is exposed by changing the shape of the finger padding prevention rubber 15 without forming the step surface 19 in the door front end surface of the door frame 17. It is something that is not allowed to occur.
