本発明はエレベータ−のドア装置に係り、特に２枚戸片
開き方式の乗場戸を有するニレベーター−のドア装置に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a door device for an elevator, and more particularly to a door device for an elevator having a two-door single-opening landing door.
一般に、エレベータ−のドア装置における駆動方式は、
２枚戸両開き方式と、２枚戸片開き方式とに大別するこ
とができる。Generally, the drive system for elevator door devices is as follows:
They can be roughly divided into two-door double-door systems and two-door single-door systems.

ることができる。The former two-door double-swing door system has an excellent design because the two doors are flush when closed, but on the other hand, it requires space to store the door pockets on both the left and right sides of the car. , the area of the hoistway becomes relatively large. Therefore, when it is desired to make the area of the hoistway smaller than the former, the latter two-door single-swing door device is adopted. In this latter door device, the door on the door pocket side is located on the landing side, and the door on the door stop side is located on the car side, and is opened and closed respectively, and in the closed state, the two doors are overlapped. Since it can be stored on one side of the car, the area of the hoistway can be made smaller than in the former case.

側の戸は戸袋側の戸よりもその厚さ分だけ乗場側に突出
して段差が生じ、２枚戸両開き方式のものに比べて意匠
性が劣るという欠点があった。Conventional two-door single-swing elevator door devices had the above-mentioned configuration, so when the door is closed, the door on the door stop side protrudes toward the landing side by the thickness of the door on the door bag side. This had the disadvantage that there was a difference in level and the design was inferior to the two-door double-door type.
本発明の目的とするところは、閉戸状態にある２枚戸片
開き方式の戸の意匠性を高めたエレベータ−のドア装置
を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator door device that improves the design of a two-panel door that opens in a closed state.

い。Since the elevator door device according to the present invention has the above-described configuration, when the door on the door stop side reaches the closed end, the drive device pushes this door toward the landing side, and the guide device pushes the door toward the door compartment side. Since the shutters are regulated to be almost flush, the shutters in the closed state are almost flush and have the same appearance as the closed state of a two-panel double-door system, which improves the design. In addition, when opening the door, the drive device first pulls the door on the door stop side toward the passenger car, and then the normal door opening/closing device operates the door in the opening direction, so the shutter can be stacked on top of the door pocket on one side of the car. The benefits remain intact.
以下本発明の実施例を図面と共に説明する。 Embodiments of the present invention will be described below with reference to the drawings.

クピニオン等によって同軸方向の駆動力に変換される。Normally, the position of the door stopper 2 that makes up the landing door is almost the closed position shown by the - dotted chain line, but it is pushed toward the landing side by the drive device ■0 and is almost the same as the opening/closing line of the door bag number 3. It is located on the line. Therefore, the door stopper 2 and the door bag number 3 that make up the landing door are flush as shown by the solid line, just like in a two-panel double door system. The drive device 10 may have its own drive source, or may have a drive force branched from a normal door opening/closing device, but its drive shaft 30 may have a drive force in the coaxial direction using a rack and pinion or the like. converted.

、この移動を阻止しないよう係合ローラ９は、隙間３３
を有した１対の保合子１１間に配置されている。A retaining roller 9 is rotatably attached to the tip of the drive shaft 30, and rotation of the drive shaft 30 drives the engagement roller 9 to the position shown by the dashed line and solid line in FIG. The engagement roller 9 can be connected to the rear surface of the door stopper 2 by means of a retainer 11. In other words, since the retaining roller 9 is located between the pair of retainers 11 fixed to the door stop 2, when a force is applied to the retaining roller 9 in the left and right direction in FIG. The opening/closing operation force is 2. Further, the engaging element 11 has a folded part 12 on the opposite side, and this folded part 12 allows the engaging roller 9 and the retaining element 11 to be connected to each other.
The space between them is also connected in the axial direction of the drive shaft 30. Therefore, when the drive shaft 30 is rotated to drive the engagement roller 9 from the solid line position to the dashed-dotted line position, it is possible to drive several doors 2 per door from the solid line position to the dashed-dotted line position. At this time, the door stop 2 moves obliquely as shown in FIG.
It is arranged between a pair of retainers 11 having a .

置させることができるなら切欠き１４は不要である。As can be seen in particular from FIG. 1, the drive device 10 is attached to the car door on the car side, so it moves up and down as the car goes up and down. Therefore, since the drive shaft 30 and the engagement roller 9 protrude toward the hall side, they collide with the hall sill 13, so that a notch 14 is formed in the hall sill 13 as shown in FIG.
to avoid this collision. Furthermore, this drive shaft 30
The cutout 14 is not necessary if the engagement roller 9 can be positioned at the opposing distance G between the thresholds 4 and 13.
次に各戸の開閉方向の案内構造について第１図を用いて
説明する。Next, the guide structure for the opening and closing directions of each door will be explained using FIG. 1.

移動する。On the other hand, for landing doors, for example, number 2 per door, the lower end is the landing threshold 1.
3 and the upper part is guided by rails 17 via hangers 15 and rollers 16. The number of doors per door 2 is opened and closed by a door opening/closing device (not shown).
The opening/closing operation force is transmitted via the drive device IO, and the opening/closing operation force is normally moved along the sill groove on the car side of the landing sill 13.

ないようにされている。Basically, two grooves are formed in the landing sill 13, namely, a groove 23 for each door and a groove 24 for each door. The groove 23 for each door per door has an inclined groove 22 formed to protrude obliquely toward the landing side in response to the movement of the rail 17 shown in FIG. When guided to the groove 23 near the entrance of this inclined groove 22, the drive device 1 in FIG.
When a pushing force is applied to the landing side by 0, the operating force in the closing direction by the door opening/closing device (not shown) will push the upper end of each door 2 toward the landing side at an angle along the inclined groove 22. , when the door is closed, it can be made almost on the same plane as the door pocket 3. At this time, the rear end of the door stop 2 and the front end of the door bag 3 come into contact, so as shown in FIGS. 2 and 3, the ends are approximately parallel to the inclined groove 22. . This end portion prevents the shutters 2.3 from coming into contact with each other, and also prevents a gap from forming between the shutters 2 and 3 in the closed state.
