[0002]

2. Description of the Related Art In recent years, with the advent of an aging society and the need for welfare, such as the protection of pregnant women, the installation of an elevator has been strongly desired even in a two- or three-story private house. . However, conventional elevators have evolved in response to the demands of offices and large apartment buildings. Therefore, even if the elevators suitable for these are simply reduced in size, the efficiency of installation space and economy for private homes can be reduced. Various unsuitable points arise from these points. That is, a conventional general elevator apparatus is, for example, as shown in FIG. FIG. 5 is a side sectional view of a conventional elevator apparatus, wherein 1 is a hoistway, 2
Is a machine room for installing a driving device 3 such as a hoisting machine provided above the hoistway 1, 4 is a guide rail for guiding a car 5 fixed to left and right wall surfaces of the hoistway 1, 6 is a main rope, One end is fixed to the upper beam 5a of the main frame of the car 5 and the other end is
Is connected to a counterweight 9 via a sheave 7 and a deflecting wheel 8 driven by the hoisting machine, so that the car 5 can be moved up and down by the driving force of the hoist. Reference numeral 10 denotes a counterweight guide rail erected on the rear side of the car 5, and reference numeral 11 denotes a governor. The governor 11 is provided with a governor rope 13 in endless proximity to the car 5. Have been. According to the conventional elevator device configured as described above, the machine room 2 in which the driving device 3 such as a hoist is disposed is provided above the hoistway 1, and the entire installation height of the elevator device is high. In the case of small-scale buildings and the like, there are problems such as restrictions on the right to sunshine and the like due to laws and regulations, which makes them unsuitable as small elevator devices for houses.

In view of the above, a machine room provided above a hoistway is made as small as possible so that the overall height of the installation of the elevator apparatus is kept low to meet the needs of a small elevator apparatus for a private house. As shown in FIG. 6, a basement type elevator apparatus having a configuration in which a machine room is provided adjacent to a lower portion of a hoistway has been developed.

[0004]

However, in the conventional elevator apparatus as described above, a drum-type hoisting machine or the like protruding outward from the hoistway is disposed adjacent to the side surface of the hoistway. It is necessary to provide the machine room separately, and therefore, there is a problem that the layout of the space in the machine room is complicated particularly in an elevator device for a private house which requires a large space saving. Further, in the conventional elevator apparatus having a machine room above the hoistway, a machine room dedicated to the elevator must be built at the top of the building, which is not suitable for a residential building in an urban area which is easily affected by sunshine. In order to check the equipment in the machine room, stairs or passages for maintenance workers to go to the machine room must be specially provided, and the installation space is inefficient in small houses where space saving is required. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to provide a machine room of an elevator at an upper part of a building or adjacent to a hoistway without protruding outside the hoistway. An object of the present invention is to provide a small-sized elevator that can be installed in a small space.

[0006]

In a small elevator apparatus according to the present invention, a guide rail provided in a hoistway is disposed outside a hoist and a top is lower than a ceiling height of a hoist on the top floor. In addition to this, a driving device long in the width direction of the counterweight of the elevating body is installed on a mounting table fixed to the top of the guide rail.
