2. Description of the Related Art In general, a small elevator such as a home elevator in which a load cannot be applied to a building in which the elevator is installed has a steel tower, which receives a load of installation equipment, erected in a hoistway.

[0003] However, this steel tower requires a high degree of accuracy in its installation, so that its installation work costs, material costs, and the like are increased, and this is a factor that consumes a large amount of costs.

Conventionally, therefore, the elevator shown in FIG. 6 does not require a steel tower. FIG. 6 is a hoistway cross-sectional plan view showing the structure of a conventional tower-less elevator.

In the drawing, a car 1 has a guide roller 3 attached to a frame 2 of the car 1 and a landing entrance 7.
By rolling on a guide surface of a guide rail 6 fixed to a side hoistway wall 4 by a fixing member 5, the guide rail 6 guides the guide rail 6 to move up and down the hoistway.

The landing entrance 7 is fixedly supported on the guide rail 6 by a support member 8.

As described above, the conventional tower-less elevator is
The load on the building was reduced by allowing the guide rails 6 fixed to the hoistway walls 4 near the hall entrance 7 to reduce the burden on the building by allowing the loads of the car 1 and the hall entrance 7 to be all received.

An example of this type of elevator is disclosed in JP-A-5-338951.

[0009]

However, the conventional elevator has not been considered when transporting the elevator to an installation site.

That is, in a small elevator such as the above-described home elevator, a car, a guide rail, a landing doorway, and the like are assembled into a steel tower to be integrated and transported as a unit block.

However, since the conventional elevator does not have a steel tower, a large amount of reinforcing material is required in order to form a unit block, and all the reinforcing materials are non-mainly used as temporary materials used only during transportation. Therefore, the cost was high, and the cost of the entire elevator was increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator unit block capable of reducing the transportation cost of a tower-less elevator.

[0013]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned main object, the present invention relates to a guide rail erected near an entrance / exit side in a hoistway, and a guide rail provided on the front side facing the entrance / exit. In a unit block of an elevator having a combined car and a landing entrance supported by the guide rail, a car engaged with a lowermost guide rail of the guide rails is fixed to the lowermost guide rail. A bottom floor landing entrance, another guide rail opposed to the bottom guide rail and erected on the rear side of the car, and a long material connecting the bottom guide rail and another guide rail; It is characterized by comprising.

As described above, according to the present invention, there is provided a guide rail erected near the entrance side in a hoistway, another guide rail opposed to the guide rail and erected on the rear side of the car, Because a frame was formed from the lowermost guide rail and the long material connecting the other guide rails, and this frame was configured to receive the load of the car and the landing doorway,
The frame can be configured using another guide rail, which is a main component, and cost reduction can be achieved by reducing temporary materials.

In addition, since a space for transporting guide rails and landing devices on floors other than the lowest floor which is conventionally required is unnecessary, transportation costs can be reduced.

Further, according to the present invention, the other guide rail is an uppermost guide rail, and the uppermost guide rail is provided with a guide pulley unit around which a rope for suspending the car is wound and an uppermost landing entrance. Since it is fixed, the top guide rail is lifted after being brought into the installation site, and if it is connected to the upper end of the guide rail erected near the entrance side, the guide rails on all floors and the landing doorway device can be installed efficiently. .

Further, according to the present invention, the intermediate guide rail and the intermediate floor landing entrance are fixed to the uppermost guide rail, so that an elevator having a third floor or more can be similarly installed efficiently. In addition, since it is fixed to the back of the car, a compact unit block can be provided, and the transportation cost can be reduced.
