Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hoistway entrance / exit device, and more particularly to an elevator hoistway entrance / exit device suitable for being installed side by side in a building where it is difficult to obtain a hoistway space.

[0002]

2. Description of the Related Art Conventionally, for example, JP-A-58-152777.
As described in Japanese Patent Laid-Open No. 61-188381 and Japanese Patent Laid-Open No. 61-188381, a hoistway device and an entrance / exit device are incorporated in advance, and are composed of a plurality of floor units that can be sequentially stacked along a wall of a building. A free-standing elevator hoistway has been proposed. In an elevator hoistway like this,
By dividing the elevator hoistway in advance and incorporating the equipment in the hoistway and the entrance / exit device to form a plurality of floor units, these floor units can be installed in existing facilities where it is difficult to obtain space for the hoistway, for example. The layers are sequentially stacked along the wall of the building, whereby the elevator hoistway can be installed in parallel with the building.

FIG. 3 is a longitudinal sectional view showing an example of this type of elevator hoistway, and FIG. 4 is a perspective view of the entrance / exit device of the floor unit provided in the elevator hoistway of FIG. 3 as seen from the building side. . The elevator hoistway 1 shown in FIG. 3 is composed of, for example, six floor units 1a to 1f which are sequentially stacked along the wall portion 3 of the building 2, and the floor units 1a to 1f.
The height of each f is set according to the space between the floors 4 of the building 2. Floor unit 1a above
The equipment in the hoistway (not shown) is installed in advance in 1f, and the doorway device 5 is also installed in advance in the other floor units 1b to 1f except the lower floor unit 1a. In the vicinity of the lower part of the elevator hoistway 1, a machine room 6 for accommodating a drive device (not shown) is installed, and the car 7 is moved up and down in the elevator hoistway 1 by driving the drive device. There is. Building 2 above
An opening 3a for entrance and exit is formed in each of the floors 4 in the wall portion 3 by a hanging operation or the like.

Further, for example, an entrance / exit device 5 provided in the floor unit 1c is provided with an entrance / exit frame 8 and an entrance / exit door 9 which is openably and closably provided inside the entrance / exit frame 8 and faces the opening 3a of the wall portion 3. Includes an entrance / exit pocket 10 for engaging the upper part of the entrance / exit door 9 and holding a door guide rail (not shown), and an entrance / exit sill 11 for guiding the lower part of the entrance / exit door 9 to the other floor units 1b, 1d to f. The same applies to the entrance / exit devices 5 provided.

[0005]

By the way, in the above-mentioned prior art, in order to arrange the entrance / exit devices 5 preliminarily incorporated in the floor units 1a to 1f at a predetermined height position with respect to the floor 4, respectively. However, there is a problem in that it requires a detailed meeting in advance with a worker who installs the elevator hoistway 1 and another worker who builds the building 2, which takes time. Further, even if such a preliminary meeting is performed, since a hanging operation or the like is used when the opening 3a for the entrance / exit is provided in the wall portion 3 of the building 2, a considerable work error occurs and the floor 4 and the entrance / exit device 5 There was a concern that a step would be formed between the entrance and exit threshold 11 of the above. Therefore, there is a problem that it takes time to repair the steps, and on the other hand, if the steps are left unattended, the passengers stumble when entering or exiting the car 7, which reduces the safety of the passengers. there were.

A method of mounting the doorway device 5 after sequentially stacking the floor units 1a to 1f is also conceivable.
In this case, although it is easy to arrange the doorway device 5 at a predetermined height position with respect to the floor 4, the doorway frame 8 of the doorway device 5 and the like are carried into the floor units 1a to 1f. It is extremely difficult to do so, and there is a problem that the installation work also takes time.

The present invention has been made in view of the circumstances in the prior art as described above, and an object thereof is to perform a quick alignment with respect to the building after the floor units are sequentially stacked along the wall of the building. An object is to provide an elevator hoistway entrance / exit device.

[0008]

In order to achieve this object, the present invention provides an opening formed in a plurality of floor units that are sequentially stacked along a wall of a building and are formed in the wall. In an entrance / exit device for an elevator hoistway, which includes an entrance / exit door facing each other, and an entrance / exit pocket and an entrance / exit threshold that respectively engage with an upper portion and a lower portion of the entrance / exit door, a mounting position for adjusting a relative mounting position with respect to the floor unit It is configured to have adjusting means.

[0009]

Since the present invention is constructed as described above, after the floor units are sequentially stacked along the wall of the building, the mounting position adjusting means relatively attaches the doorway device to the floor unit. Adjust the position. Accordingly, the entrance / exit device can be quickly aligned with the building in which the floor unit is installed.
