In the figure, the door panel 11 has a panel member 14 and a back member 15 provided on the back side of the panel member 14. The panel member 14 and the back member 15 are continuous with each other at the width direction end of the door panel 11. The door panel 11 is formed by bending a single plate (such as a steel plate).

パネル部材１４は、意匠面を形成するパネル表板１６と、パネル表板１６の幅方向両端部に設けられ、パネル表板１６の裏側で互いに対向する一対の対向部１７，１８とを有している。一方の対向部１７はドアパネル１１の戸閉側端部（戸当たり側端部）に設けられ、他方の対向部１８はドアパネル１１の戸開側端部（戸袋側端部）に設けられている。   The panel member 14 includes a panel surface plate 16 that forms a design surface, and a pair of facing portions 17 and 18 that are provided at both ends in the width direction of the panel surface plate 16 and face each other on the back side of the panel surface plate 16. ing. One facing portion 17 is provided at the door closing side end portion (door end side end portion) of the door panel 11, and the other facing portion 18 is provided at the door opening side end portion (door bag side end portion) of the door panel 11. .

The panel parallel part 17b extended in the direction which approaches the center of the door panel 11 from. Further, the facing portion 18 includes a panel vertical portion 18a extending in the thickness direction of the door panel 11 from the door opening side end portion of the panel front plate 16, and a front end portion of the panel vertical portion 18a (an end on the side away from the panel front plate 16). Panel parallel part 18b extending in a direction approaching the center of the door panel 11 from the part).

裏部材１５は、ドアパネル１１の戸閉側端部でパネル部材１４と連続する第１の裏部材１９と、ドアパネル１１の戸開側端部でパネル部材１４と連続する第２の裏部材２０とにより構成されている。第１の裏部材１９及び第２の裏部材２０のそれぞれとパネル部材１４とが互いに連続する各部分は、板をほぼ１８０度折り返すヘミング曲げ加工により形成されている。   The back member 15 includes a first back member 19 that is continuous with the panel member 14 at the door closing side end of the door panel 11, and a second back member 20 that is continuous with the panel member 14 at the door opening side end of the door panel 11. It is comprised by. Each portion where the first back member 19 and the second back member 20 and the panel member 14 are continuous with each other is formed by a hemming bending process in which the plate is folded back approximately 180 degrees.

第１の裏部材１９は、その全部がパネル部材１４の裏面に重ねられた裏側重ね部とされている。この例では、第１の裏部材１９は、パネル平行部１７ｂにのみ重ねられている。   The first back member 19 is a back-side overlap portion in which all of the first back member 19 is overlapped on the back surface of the panel member 14. In this example, the first back member 19 is overlapped only on the panel parallel part 17b.

第２の裏部材２０は、パネル部材１４の裏面に重ねられた裏側重ね部２１と、裏側重ね部２１に設けられ、パネル部材１４から開離された裏側開離部２２とを有している。   The second back member 20 includes a back side overlapping portion 21 that is overlapped on the back surface of the panel member 14, and a back side opening portion 22 that is provided on the back side overlapping portion 21 and is separated from the panel member 14. .

裏側重ね部２１は、対向部１８の端部からパネル垂直部１８ａに近づく方向へパネル平行部１８ｂに沿って延びる重ね平行部２１ａと、重ね平行部２１ａの先端部（パネル垂直部１８ａに近い側の端部）からパネル表板１６に近づく方向へパネル垂直部１８ａに沿って延びる重ね垂直部２１ｂと、重ね垂直部２１ｂの先端部（パネル表板１６に近い側の端部）からドアパネル１１の中央に近づく方向へパネル表板１６に沿って延びる重ね表板部２１ｃとを有している。重ね表板部２１ｃの水平方向寸法は、パネル表板１６の水平方向寸法よりも小さい所定の寸法とされている。   The back side overlapping portion 21 includes an overlapping parallel portion 21a extending along the panel parallel portion 18b in a direction approaching the panel vertical portion 18a from the end portion of the facing portion 18, and a front end portion (side closer to the panel vertical portion 18a) of the overlapping parallel portion 21a. The overlapping vertical portion 21b extending along the panel vertical portion 18a in a direction approaching the panel surface plate 16 from the end portion of the door panel 11, and the front end portion of the overlapping vertical portion 21b (the end portion closer to the panel surface plate 16). It has a superposed surface plate portion 21c extending along the panel surface plate 16 in a direction approaching the center. The horizontal dimension of the overlapped surface plate portion 21 c is a predetermined dimension smaller than the horizontal dimension of the panel surface plate 16.

裏側開離部２２は、重ね表板部２１ｃの先端部（ドアパネル１１の戸閉側端部に近い側の端部）からドアパネル１１の厚さ方向へ延びる開離垂直部２２ａと、開離垂直部２２ａの先端部（パネル表板１６から離れた側の端部）から戸閉側へ延びる開離平行部２２ｂとを有している。   The back side separation part 22 is a separation vertical part 22a that extends in the thickness direction of the door panel 11 from the front end part (the end part close to the door closing side end part of the door panel 11) of the overlapping surface plate part 21c, and the separation vertical part. And an opening parallel portion 22b extending from the tip end portion (the end portion on the side away from the panel surface plate 16) to the door closing side.

ドアパネル１１は、戸閉側端部及び戸開側端部をそれぞれ以下のようにして形成することにより製造される。   The door panel 11 is manufactured by forming a door closing side end and a door opening side end as follows.

即ち、一枚の鋼板の一端部をヘミング曲げ加工により折り返し、折り返した部分を第１の裏部材１９とする。この後、第１の裏部材１９が重なった部分を避けて鋼板を曲げ、対向部１７を形成する。このようにして、ドアパネル１１の戸閉側端部が形成される。   That is, one end of one steel plate is folded by hemming bending, and the folded portion is used as the first back member 19. Thereafter, the steel plate is bent to avoid the portion where the first back member 19 overlaps, and the facing portion 17 is formed. In this way, the door closing side end of the door panel 11 is formed.

また、鋼板の他端部を曲げて裏側開離部２２を形成した後、鋼板の裏側開離部２２を含む部分をヘミング曲げ加工により折り返す。この後、鋼板の折り返しにより重なった部分をまとめて曲げて、対向部１８及び裏側重ね部２１を形成する。このようにして、ドアパネル１１の戸開側端部が形成される。   Moreover, after bending the other end part of a steel plate and forming the back side separation part 22, the part containing the back side separation part 22 of a steel plate is turned back by hemming bending. Thereafter, the overlapping portions by folding the steel plates are bent together to form the facing portion 18 and the back side overlap portion 21. In this way, the door opening side end of the door panel 11 is formed.

即ち、ドアパネル１１の戸閉側端部は、パネル部材１４が単独で曲げられた単独曲げ構造とされ、ドアパネル１１の戸開側端部は、パネル部材１４及び裏側重ね部２１がまとめて曲げられた重ね曲げ構造とされている。   That is, the door closing side end portion of the door panel 11 has an independent bending structure in which the panel member 14 is bent alone, and the door opening side end portion of the door panel 11 is bent together by the panel member 14 and the back side overlapping portion 21. It is a lap bending structure.

ここで、重ね曲げ構造は、パネル部材１４及び裏側重ね部２１がまとめて曲げられているので、パネル部材１４が裏側重ね部２１よりも緩やかな曲がりになる。従って、重ね曲げ構造とすることにより、ドアパネル１１の意匠性が低下してしまう。このことから、エレベータの出入口の側部により常時隠されているドアパネル１１の戸開側端部にのみ重ね曲げ構造を適用するのが好ましい。   Here, since the panel member 14 and the back side overlapping portion 21 are bent together in the overlapping bending structure, the panel member 14 is bent more gently than the back side overlapping portion 21. Therefore, the design property of the door panel 11 will fall by setting it as an overlap bending structure. Therefore, it is preferable to apply the lap bending structure only to the door opening side end portion of the door panel 11 that is always hidden by the side portion of the elevator doorway.

このようなエレベータのドアでは、パネル部材１４と裏部材１５とがドアパネル１１の幅方向端部で互い連続し、パネル部材１４と裏部材１５とが互いに連続する部分が鋼板の曲げ加工により形成され、裏部材１５は、パネル部材１４の裏面に重ねられた裏側重ね部を有しているので、鋼板を曲げ加工するだけでドアパネル１１を容易に作製することができ、製造コストの低減を図ることができる。また、鋼板の曲げによる補強、及び裏部材１５による補強のそれぞれにより、ドアパネル１１の強度も確保することができる。   In such an elevator door, the panel member 14 and the back member 15 are continuous with each other at the end in the width direction of the door panel 11, and the portion where the panel member 14 and the back member 15 are continuous with each other is formed by bending a steel plate. Since the back member 15 has a back side overlapping portion that is overlapped on the back surface of the panel member 14, the door panel 11 can be easily produced simply by bending the steel plate, and the manufacturing cost can be reduced. Can do. Further, the strength of the door panel 11 can be ensured by the reinforcement by bending the steel plate and the back member 15.

さらに、ドアパネル１１の幅方向端部が鋼板を曲げて形成されているので、ドアパネル１１の裏側で鋭利な部分を無くすことができる。従って、例えば乗客の手等がドアパネル１１の裏側に挿入された場合であっても、ドアパネル１１で乗客の手を切ることを防止することができる。   Furthermore, since the end portion in the width direction of the door panel 11 is formed by bending a steel plate, a sharp portion on the back side of the door panel 11 can be eliminated. Therefore, for example, even when a passenger's hand or the like is inserted into the back side of the door panel 11, it is possible to prevent the passenger's hand from being cut by the door panel 11.

即ち、図４は、図１のかごドア４と乗場ドア６との間に乗客の手が挿入されているときの状態を示す水平断面図である。図に示すように、乗客の手２５がかごドア４と乗場ドア６との間に挿入された場合、乗客の手２５がドアパネル１１の裏面に接触することがある。この場合、乗客の手２５が接触する部分が曲げ加工により緩やかな曲面になっているので、ドアパネル１１で乗客の手２５を切ることを防止することができる。   That is, FIG. 4 is a horizontal sectional view showing a state when a passenger's hand is inserted between the car door 4 and the landing door 6 of FIG. As shown in the drawing, when the passenger's hand 25 is inserted between the car door 4 and the landing door 6, the passenger's hand 25 may come into contact with the back surface of the door panel 11. In this case, since the portion where the passenger's hand 25 comes into contact has a gently curved surface by bending, it is possible to prevent the passenger's hand 25 from being cut by the door panel 11.

また、パネル部材１４と裏部材１５とが互いに連続する部分は、ヘミング曲げ加工により形成されているので、ドアパネル１１の製造をさらに容易にすることができる。   Moreover, since the part which the panel member 14 and the back member 15 follow mutually is formed by hemming bending process, manufacture of the door panel 11 can be made still easier.

また、ドアパネル１１の戸開側端部は、パネル部材１４及び裏側重ね部２１がまとめて曲げられた重ね曲げ構造とされているので、ドアパネル１１の強度の向上をさらに図ることができる。   Moreover, since the door opening side edge part of the door panel 11 is made into the overlapping bending structure where the panel member 14 and the back side overlap part 21 were bent collectively, the improvement of the intensity | strength of the door panel 11 can further be aimed at.

また、ドアパネル１１の戸開側端部のみが重ね曲げ構造とされているので、ドアパネル１１の意匠性が低下している部分をエレベータの出入口の側部で隠すことができ、エレベータのドアの意匠性の向上を図ることができる。   Moreover, since only the door opening side edge part of the door panel 11 is made into the overlapping bending structure, the part in which the designability of the door panel 11 has fallen can be hidden by the side part of the entrance / exit of an elevator, and the design of the door of an elevator It is possible to improve the performance.

なお、上記の例では、ドアパネル１１の戸開側端部のみが重ね曲げ構造とされているが、ドアパネル１１の意匠性の低下を許容することができるのであれば、ドアパネル１１の戸閉側端部も重ね曲げ構造としてもよい。このようにすれば、ドアパネル１１の強度の向上をさらに図ることができる。   In the above example, only the door opening side end portion of the door panel 11 has a lap bending structure. However, if the design of the door panel 11 can be lowered, the door closing side end of the door panel 11 can be allowed. The part may also have a lap bending structure. In this way, the strength of the door panel 11 can be further improved.

また、上記の例では、パネル部材１４及び裏部材１５のみでドアパネル１１の強度が確保されるようになっているが、例えば裏側開離部２２及び対向部１７間にドアパネル１１とは別個の補強部材を取り付けてもよい。この場合、補強部材は、裏側開離部２２及び対向部１７のそれぞれに例えばねじ等により取り付けられる。このようにすれば、ドアパネル１１の強度の向上をさらに図ることができる。また、溶接と異なる方法によりドアパネル１１に補強部材を取り付けることができるので、ドアパネル１１の変形を抑制することができる。   Further, in the above example, the strength of the door panel 11 is ensured only by the panel member 14 and the back member 15, but, for example, a reinforcement separate from the door panel 11 between the back side opening portion 22 and the facing portion 17. A member may be attached. In this case, the reinforcing member is attached to each of the back-side separation portion 22 and the facing portion 17 with, for example, screws. In this way, the strength of the door panel 11 can be further improved. Moreover, since a reinforcement member can be attached to the door panel 11 by a method different from welding, deformation of the door panel 11 can be suppressed.

また、上記の例では、開離平行部２２ｂが開離垂直部２２ａの先端部から戸閉側へ延びるように形成されているが、図５に示すように、開離垂直部２２ａの先端部から戸開側へ延びるように開離平行部２２ｂを形成してもよい。   Further, in the above example, the separation parallel portion 22b is formed to extend from the distal end portion of the separation vertical portion 22a to the door closing side, but as shown in FIG. 5, the distal end portion of the separation vertical portion 22a. The separating parallel part 22b may be formed so as to extend from the door to the door opening side.

6 is a horizontal sectional view showing a door panel 31 according to Embodiment 2 of the present invention. In the figure, the door panel 31 has the same panel member 14 as in the first embodiment and a back member 32 provided on the back side of the panel member 14. The panel member 14 and the back member 32 are continuous with each other at the end in the width direction of the door panel 31. The door panel 31 is formed by bending a single plate (for example, a steel plate).

裏部材３２は、ドアパネル３１の戸閉側端部でパネル部材１４と連続する第１の裏部材３３と、ドアパネル３１の戸開側端部でパネル部材１４と連続する第２の裏部材３４とにより構成されている。第１の裏部材３３とパネル部材１４とが互いに連続する部分は、板を鈍角に曲げる曲げ加工により形成されている。また、第２の裏部材３４とパネル部材１４とが互いに連続する部分は、板をほぼ１８０度折り返すヘミング曲げ加工により形成されている。   The back member 32 includes a first back member 33 that is continuous with the panel member 14 at the door closing side end of the door panel 31, and a second back member 34 that is continuous with the panel member 14 at the door opening side end of the door panel 31. It is comprised by. The portion where the first back member 33 and the panel member 14 are continuous with each other is formed by a bending process of bending the plate at an obtuse angle. Further, a portion where the second back member 34 and the panel member 14 are continuous with each other is formed by a hemming bending process in which the plate is folded back approximately 180 degrees.

第１の裏部材３３は、対向部１７の端部からパネル表板１６に近づく方向へ延びる裏側開離部３３ａと、裏側開離部３３ａの先端部（パネル表板１６に近い側の端部）からドアパネル３１の中央に近づく方向へ延びる裏側重ね部３３ｂとを有している。裏側重ね部３３ｂは、パネル表板１６の裏面に重ねられている。   The first back member 33 includes a back side opening portion 33a extending from the end portion of the facing portion 17 in a direction approaching the panel surface plate 16, and a front end portion of the back side opening portion 33a (an end portion on the side close to the panel surface plate 16). ) To the center of the door panel 31. The back side overlapping portion 33 b is overlapped with the back surface of the panel front plate 16.

第２の裏部材３４は、実施の形態１と同様の裏側重ね部２１と、裏側重ね部２１に設けられ、パネル部材１４から開離された裏側開離部３５とを有している。裏側開離部３５は、裏側重ね部２１の重ね表板部２１ｃの先端部からドアパネル３１の厚さ方向へ延びている。即ち、パネル表板１６に垂直に配置された板のみが裏側開離部３５とされている。他の構成は実施の形態１と同様である。   The second back member 34 includes a back side overlap portion 21 similar to that of the first embodiment, and a back side opening portion 35 provided in the back side overlap portion 21 and separated from the panel member 14. The back-side separation part 35 extends in the thickness direction of the door panel 31 from the front end part of the overlapping surface plate part 21 c of the back-side overlapping part 21. That is, only the plate arranged perpendicular to the panel front plate 16 is the back side separation portion 35. Other configurations are the same as those in the first embodiment.

このようにしても、鋼板を曲げ加工するだけでドアパネル３１を容易に作製することができ、製造コストの低減を図ることができる。また、鋼板の曲げによる補強、及び裏部材３２による補強のそれぞれにより、ドアパネル３１の強度も確保することができる。さらに、例えば乗客の手等がドアパネル３１の裏側に挿入された場合であっても、ドアパネル３１で乗客の手を切ることを防止することができる。   Even if it does in this way, the door panel 31 can be easily produced only by bending a steel plate, and reduction of manufacturing cost can be aimed at. Moreover, the strength of the door panel 31 can be ensured by the reinforcement by bending the steel plate and the reinforcement by the back member 32. Furthermore, even when a passenger's hand or the like is inserted into the back side of the door panel 31, it is possible to prevent the passenger's hand from being cut by the door panel 31.

また、パネル部材１４と裏部材３２とが互いに連続する部分が鈍角に曲げられて形成されているので、ドアパネル３１をさらに容易に作製することができる。   Moreover, since the part which the panel member 14 and the back member 32 mutually follow is formed by bending at an obtuse angle, the door panel 31 can be produced still more easily.

また、パネル表板１６に垂直に配置された板のみが裏側開離部３５とされているので、実施の形態１よりも少ない材料でドアパネル３１を作製することができ、ドアパネル３１の材料コストの低減を図ることができる。   Moreover, since only the board | substrate arrange | positioned at right angles to the panel surface board 16 is made into the back side separation | separation part 35, the door panel 31 can be produced with a material less than Embodiment 1, and the material cost of the door panel 31 is low. Reduction can be achieved.

なお、実施の形態２の第１の裏部材３３及び第２の裏部材３４のいずれかの構造を実施の形態１のドアパネル１１に適用してもよい。

Any structure of the first back member 33 and the second back member 34 of the second embodiment may be applied to the door panel 11 of the first embodiment.
