Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to an elevator door device.

[Conventional technology]

Conventionally, it was used as an elevator door device in 1986-263.
There was one shown in Publication No. 76. This door device opens and closes the doorway that opens at the front of the car using a horizontal sliding door that is linked to the landing door.A door pocket is provided on the side of the entrance/exit row at the front of the car to store the door when the horizontal sliding door is opened. It is something that

Furthermore, there has conventionally been an elevator door device disclosed in Japanese Unexamined Patent Publication No. 53-43349. This door device is provided with a folding door in which a plurality of plates are foldably connected in the width direction at the entrance/exit of a car, and the plate is folded parallel to the depth direction of the car to open the entrance/exit. These are expanded into a continuous V-shape with a large opening angle to close the entrance/exit.

[Problem that the invention seeks to solve]

Incidentally, in recent years, with the arrival of an aging society, there has been a demand for elevators to be installed even in private residences on the second or third floor. However, as conventional elevators have developed in response to demand for offices, apartment buildings, etc.,
If the door device that opens and closes the car entrance with a single horizontal sliding door as shown in Publication No. 6376 is simply miniaturized,
Due to space usage efficiency and economic efficiency, it is no longer suitable for small elevators for private residences. In other words, elevators for private residences have a capacity of about 1 to 2 people, so a small car with a width of 1 inch or less is sufficient, but if you take into account access using a wheelchair, the width of the entrance should be 0.8 m.
degree required. On the other hand, the above-mentioned Jikko Sho 55-2
In the door device shown in Publication No. 6376, the frontage of the car is 1.
-1 tn, if the width of the entrance is 0.8 m, the door pocket will protrude outward from one side of the car, which will increase the frontage of the hoistway and reduce the efficiency of space utilization. I end up.

Therefore, it has been proposed in Japanese Patent Application Laid-Open No. 53-43349 that a folding door in which a plurality of plates are connected in the width direction is provided at the entrance/exit of the car. The frontage dimension of the basket in the folded state can be reduced, but the depth dimension increases and a large space is required inside the basket for the opening and closing operation. The depth dimension of the car in the tatami state is shortened, but conversely, the width dimension of the car in the width direction becomes larger due to the thickness of the numerous plates, and the width of the hoistway becomes larger. There was a problem in that it was difficult to satisfy the requirements of small elevators.

The present invention solves the above-mentioned problems and allows the car to be folded into a simple structure that reduces the depth and frontage dimensions, and allows the door pocket to hardly protrude from one side of the car, thereby making the most of the installation space of the elevator. It is an object of the present invention to provide an elevator door device that is efficient, economical, and suitable for elevators for private residences.

[Means for solving problems]

The elevator door device according to the present invention has a door provided at the entrance/exit of a car, in which a flexible sheet having a wavy horizontal cross section is fixed to a plurality of parallel columns.

[For production]

Since the door device according to the present invention uses a flexible sheet with a wavy horizontal cross section for the car door, even if the number of irregularities such as continuous ■ shapes forming the waves of the flexible sheet is increased, Although the flexible sheet has a thin thickness and has a simple structure that does not require connecting members such as hinges that connect uneven parts to each other in a bendable manner, the depth and frontage dimensions of the car when the door is folded are small. can be made smaller, making efficient use of the elevator installation space and being economical.

As shown in FIGS. 2 and 3, the door 6 provided at the entrance of the car 3 has a main pillar 7 at the front edge, a door pocket pillar 8 at the rear edge, and a child pillar 9 interposed between these pillars. are arranged vertically at equal mutual intervals, and the back surface of a flexible sheet 10 having a horizontal cross-sectional wavy (concert-like) shape and having a large number of concave and convex portions formed in a continuous V shape is fixed to the pillars 7, 8.9. It is what was done. Door bag pillar 8 is door bag 3 of basket 3
The upper end is fixed to the car girder 11 and the lower end is fixed to the sill 12, respectively.

The pillars 7, 8, and 9 are connected by a link mechanism 13,
The link mechanism 13 includes a link lever 14n which is pivotally connected to the main pillar 7 and the door pocket pillar 8 in a box shape and an inverted dog shape at both ends,
A link lever 14b whose intermediate portion intersects in an X-shape and is pivotally connected to the armature 9 is pivotally connected to each other. A hanger plate 15 is fixed to the upper end of the main pillar 7, and a hanger roller 15a is arranged on the upper part of the plate 15, and an up thrust roller 1.5b is arranged on the lower part of the plate 15, and the plate 15 is pivoted two by two in the opening/closing direction of the door 6. has been done. Doorway 5 of car 3
A hanger rail 16 is installed along the left-right direction on the upper girder 11, and a hanger roller 15a and an up thrust roller 15b are rollably abutted on the upper surface of the hanger rail 16 and the lower surface of the hanger rail 16, respectively. . Hanger rollers 17 are each pivotally connected to the upper end of the child post 9,
Hanger four-ra 17ζ: [, It is rotatably supported by UF3fIIt of the sub-rail 27 installed below the hanger rail 16 above the entrance 5 of the car 3. Main pillar 7.
Guide members 18a and 18b are provided at the lower end of the lower post 9, respectively.
The guide members 18a, 18bζ are configured to be supported and guided in a sill groove 12a formed along the left-right direction in the sill 12 below the entrance 5 of the elevator car 3. Further, one horizontal sliding door 19 is arranged at the entrance 4 of the landing 1, and a plate-shaped engagement member 21 that removably engages with a recess of an engaging element 20 provided at the front edge of the horizontal sliding door 19 is provided. It is fixed to the upper part of the main pillar 7 via a hanger plate 15. Above digit 1

A drive gear 22 is rotatably attached, an endless toothed belt 23 is engaged and supported between the freewheel 22 and the drive gear 22, and a connecting fitting 24 fixed to the hanger plate 15 is clamped and fixed to this belt 23. Kakeru! An electric motor 25 with a built-in speed reducer fixed to the girder 11 is connected to the lll1tlI car 22. In addition, the second
In the figure, 26a, 26b, 26c are the pivots of the link levers 14n, 14b.

Next, the operation of the embodiment configured as above will be explained. When the car 3 reaches the required floor, the closed door 6
The engaging member 21 provided on the main pillar 7 engages with the engaging element 20 of the closed horizontal sliding door 19 of the landing 1, and the car 3 stops. In this state, the electric motor 8125 rotates in the normal direction, and the drive tooth? 2
2. The driving force in the opening direction is transmitted to the main post 7 via the toothed belt 23, the connecting metal fittings 24 and the hanger plate 15,
The main pillar 7 moves to the door pocket pillar 8 side. In this case, the main pillar 7 moves while maintaining a vertical state by rolling the hanger rollers 15a and up thrust rollers 15b, which are provided two each on the hanger plate 15, sandwiching the hanger rail 16 from above and below. , as will be described later, the bending angle of the flexible sheet 10 is reduced (7) the lever sheet 1-10 is contracted and opened.

In addition, since the hanger rollers 15a and 15b and the hanger rail 16 provided on the hanger plate 15 of the main pillar 7 are located below the hanger 4-ra 17 and the sub-rail 27 of the child pillar 9, they interfere with each other. When the child post 9 moves to the door pocket post 8 side without being moved, the door 6 opens, and the door 6 is fully opened, the convex portions of the flexible sheet 10 are almost in close contact with each other, and the main post 7. The child pillar 92 and the door pocket pillar 8 are housed in the door pocket 4 in close contact with the adjacent pillar. Further, in this RMM air, the link mechanism 13 prevents the main column force from being directly applied to the door pocket column 86III from the child column 9 of the flexible sheet 10. Therefore, the flexible sheet 10 can be shrunk without undue load or deformation, and can maintain a long lifespan. Furthermore, since the main pillar 7, the child pillar 9, and the door pocket pillar 8 maintain equal distances from each other and move while reducing the distance between them, each pillar 7. It also prevents damage to pillars caused by '11,8's colliding with each other and being pushed too hard. When the main pillar 7 is opened, the engaging member 21 and the engaging element 20 are engaged, so that the horizontal sliding door 19 of the landing 1 is also linked (7) and opened. With the door 6 and the horizontal sliding door 19 open, People and wheelchairs get on and off between car 3 and landing 1 through doorways 5 and 4. Then, by operating electric power +1125 and reverse wA, door 6 and side sliding door are opened in the opposite manner to the opening described above. 19, and then move the car 3 up and down.In this embodiment, the link mechanism 13 is installed at a height approximately midway between each column 8. Even if the flexible sheet 10 between the pillars 7, 8, or the like is pushed due to the movement of the cargo, safety is high because the sheet 10 can be prevented from bending too much.

In addition, in this invention, the number of lower pillars is not limited to the two in the embodiment, but can be increased or decreased, and the link mechanism is not limited to one set, but may be provided in multiple pairs of upper and lower columns. Although the horizontal sliding doors are opened and closed, these may also be opened and closed manually.

〔Effect of the invention〕

As explained above, the present invention uses a wavy flexible sheet having irregularities such as a continuous V-shape in horizontal cross section fixed to a plurality of pillars as a car door, thereby increasing the depth and frontage of the car. A door that can be opened by folding down to a small dimension can be obtained with a simple structure, so the door pocket hardly protrudes from one side of the car, and the elevator installation space is efficient and economical, making it suitable for private residences. This provides the advantage of being able to provide an elevator door device suitable for various applications.
