Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator door opening/closing device, and more specifically, to a double-opening car door that opens and closes in opposite directions by a drive mechanism, and a car door that opens and closes in opposite directions when the car is located at a landing. The present invention relates to an improvement in the engagement portion between the car door and the landing door, which is engaged with the car door in the opening/closing direction and moved in conjunction with the car door only when the car door is stopped.

[Prior Art] -Alternatively, for safety reasons, the elevator is designed such that the door on the landing side is engaged with the car door in the opening/closing direction and moved in conjunction with the car door only when the car stops at the landing position. For this reason, for inward-opening doors that open and close in opposite directions in conjunction with either the left or right door, as shown in Figure 4, the landing door (1) provided at each stop floor is A protrusion, that is, a gripping member (0) is attached to the hoistway side only on either the right door (2) or the left door (3), and the car is placed in the landing position on either the left or right door (not shown) on the car side. A locking piece (5) that can be engaged in the opening/closing direction with the gripping member (4) of the landing door is provided only when the car is stopped, and these are opened and closed in conjunction with each other by a drive mechanism provided on the car side. It looks like this.

[Problems to be Solved by the Invention] In the conventional elevator door opening/closing device, the engagement portion between the landing door and the door is provided only on one side of each of the left and right doors, as described below. If the gripping member (4) of the hall door is removed when converting an existing elevator into a new elevator, there is a problem that it becomes impossible to get on and off the elevator on that floor. In addition, repairing landing doors, etc. requires a longer construction period because it requires several W stops, but in cases where one elevator is installed in a building, for example, the period of elevator downtime associated with repair work must be kept as short as possible. For this reason, it is desirable to carry out renovation work on holidays when the building is infrequently used, and to allow the elevator to be used on weekdays to avoid changing or degrading the building's features.

In view of the above points, it is an object of the present invention to obtain an elevator door opening/closing device that can be repaired while being ready for use at all times.

[Means for Solving the Problems] The elevator door opening/closing device of the present invention has a gripping member attached to a door on the landing side, which is attached to either the left or right door, and which is fixed at the car stop position between the landing door and the car door. Locking pieces are provided on both the left and right doors on the car side to enable engagement in the opening and closing directions.

[Function] In the present invention, even if the landing side gripping member is located on either the left or right door, it can be handled by the locking pieces provided on the left and right doors on the car side, so when renovating the landing door, it is especially easy to remove the existing gripping member. If construction is to be carried out on the elevator, by attaching a gripping member to the door on the side that does not have a gripping member in advance, it is possible to maintain the condition where it is possible to get on and off the elevator on the floor to be renovated.
things can continue.

[Embodiment] Hereinafter, the present invention will be described with reference to an embodiment shown in FIGS. 1 to 3, in which parts corresponding to conventional ones are denoted by the same reference numerals. In Figure 2, (8) is the gripping member (4) after the existing left door (3) at the landing has been recovered or the newly installed left door.
) has been removed, and a door hanger (7) is provided at the upper end of the ), and this door hanger (7) is attached to the upper half of the interlocking lobe (9) adjusted between the pair of pulleys (8). is connected to.

(10) is the right door of the landing, and above it, a gripping member (11) similar to the conventional one is installed in advance before the existing left door (3) is recovered or before the left door (6) is newly installed. is attached, and connected to the lower half of the L interlocking rope (9) via a door hanger (12) provided at the upper end.

Therefore, the left door (6) and the right door (10) can move in mutually opposite directions in conjunction with each other by the interlocking lobe (8).

Figure 3 shows an elevator car, and in the figure, (13) and (14) are the left and right doors of this car, and (15) is the left and right door of this car.
, (16) is the upper part of these left and right doors (13) and (14), that is, when the car stops at the landing, the right door (1
0) or the gripping member (11) provided on the left door (3)
Or (4), the engaging W pieces are fixedly attached at positions where they can be engaged in the opening/closing direction, and these are connected to a plurality of link members (17) installed at the upper end of the car and a driving machine (18). ), so that they can move in conjunction with each other in opposite directions. The link member (17) is pivotally supported at points A and B on the car frame side (not shown), and in particular, point A is set at a position where the left and right doors (13) and (14) move the same amount.

The door opening/closing position of the elevator of the present invention configured as described above is such that the respective locking pieces (15) and (1G) provided on both the left and right doors (13) and (14) on the car side are located at the left and right sides on the landing side. Gripping member (4) or (1) attached to the door frame
1), in other words, it can be used with both old and new doors on the landing side, making it possible to repair work such as renovating the landing door! Even when going outside, getting on and off the elevator can be maintained in a state where it is possible to get on and off the elevator, without degrading the building's functions.

In addition, although the driving mechanism of the elevator car door is constructed from a link member in the embodiment L, it is also possible to use a mechanism such as an interlocking lobe used in a visitor door.
Effects similar to those described above can be expected.

"Effects of the Invention" - H [As mentioned above, according to the present invention, even when repairing landing doors, etc., it is possible to continue the construction work while maintaining the state in which people can get on and off the elevator. This has the effect of not degrading building functions.
