ABSTRACT:
TECHNICAL FIELD
The present invention relates to an elevator apparatus, and more particularly, to an elevator apparatus in which a control panel is installed within a hoistway.
BACKGROUND ART
In a conventional elevator apparatus, since a hoisting machine, a control panel and the like are installed in a machine room disposed at an upper portion of a hoistway, it is necessary to provide a space for the machine room at an uppermost portion of a building. Therefore, the utility efficiency of the building is degraded and the height of the building is increased.
In contrast, for example, Japanese Patent Application Laid-Open No. 7-10434 discloses an elevator apparatus in which a hoisting machine and a control panel are disposed in an uppermost portion of a hoistway to thereby dispense with a machine room. Also, Japanese Patent Application Laid-Open No. 7-10437 discloses an elevator apparatus in which a hoisting machine and a control panel are disposed in a bottom portion of a hoistway to thereby dispense with a machine room. However, in these elevator apparatuses, although the machine room may be dispensed with, it is possible that the height of the hoistway or the horizontal cross-sectional area of the hoistway may be increased.
Also, Japanese Patent Application Laid-Open No. 10-114481 discloses an elevator apparatus in which a control panel is disposed in a bottom portion of a hoistway. However, in this apparatus, in order to prevent the car from interfering with the control panel, a depression is formed on the bottom portion of the car. For this reason, the floor area of the car is decreased.
DISCLOSURE OF THE INVENTION
In order to overcome the above-noted defect, an object of the present invention is to provide an elevator apparatus in which the height of a building may be reduced without providing any depression in a car and which can enhance the utility efficiency of a building.
According to the present invention, there is provided an elevator apparatus comprising: a hoistway having a hoistway wall and a bottom portion; an ascending/descending body having a side wall portion facing the hoistway wall and a car-mounted device projecting toward the hoistway wall from the side wall portion, the ascending/descending body being raised and lowered within the hoistway; and a control panel for controlling the raising and lowering of the ascending/descending body, the control panel being disposed within the hoistway at a position that is overlapped by a region projected from the car-mounted device in the ascending/descending direction of the ascending/descending body, and out of the movement range of the car-mounted device in the ascending/descending direction of the ascending/descending body.
Also, according to the present invention, there is provided an elevator apparatus comprising: a hoistway having a hoistway wall and a bottom portion; an ascending/descending body for being raised and lowered within the hoistway; a hoistway device provided on the hoistway wall so as to project into the hoistway; and a control panel for controlling the raising/lowering of the ascending/descending body, the control panel being disposed within the hoistway at a position that is overlapped by a region projected from the hoistway device in the ascending/descending direction of the ascending/descending body, and out of the range of the hoistway device installation region.
