[0004]

After getting on the car during maintenance and inspection, the elevator may run in response to a call at the hall, which is very dangerous for maintenance personnel. To prevent accidents by maintenance personnel, it is necessary to turn off the power switch when getting on the car during maintenance and inspection, and set the operation mode switch to the manual operation mode to prevent the car from traveling before getting on the car. is there. However, the conventional elevator car maintenance operation device is mounted on a car frame beam or the like because if it is installed at a position close to the hall, it will be an obstacle when a maintenance staff gets on the car. For this reason, depending on the size of the car, etc., it is not always in a position where it is easy to operate when getting in, so maintenance is performed by an unsafe method.

[0005] Also, when the car is run while the user is on the car and performing maintenance and inspection, the car may interfere with other devices in the hoistway or be caught in the car. There is very dangerous.

Further, when a plurality of persons board the car and perform maintenance and inspection, the number of maintenance operation devices is one, and therefore the car may be driven by the traveling switch without confirming the mutual states. Dangerous to.

Further, when inspecting the car door mechanism, it is necessary to perform it from the floor of the hall, but since the elevator can be moved on the car but cannot be operated at the hall, it is always a two-person operation, resulting in poor work efficiency. As one of the countermeasures, the pendant switch is equipped with a switch necessary for maintenance and inspection, and this pendant switch is attached to the tip of the movable cable to increase the degree of freedom of operation. Can not do it. For this reason, it may not be possible to work.

Furthermore, since the car is not normally illuminated, it is dark and very dangerous when getting on the car. As a countermeasure for this, lighting on the car is performed by using a switch in the car, but in some cases, the car may be directly put on the car without being put in the car.

Further, the maintenance operation device may be provided with a switch required for maintenance and inspection on the pendant switch, but if this pendant switch is rolled on the car, it may cause an erroneous operation of the switch, causing the elevator to run. It is very dangerous to do so.

The present invention has been made in order to solve the above-mentioned problems associated with the conventional example, and an object thereof is to obtain an elevator car maintenance operation device capable of safely and easily operating an elevator during maintenance work. It is what
