Abstract

PROBLEM TO BE SOLVED: To carry out maintenance inspection safely and easily without enlarging the dimensions of an elevator shaft by shifting a side plate of a car vertically, laterally, or the like so as to be able to perform maintenance inspection of an elevator driving hoisting machine control panel, a speed governor, and the like provided in the elevator shaft, inside and outside the car. SOLUTION: A side plate 4 of a car 2 is an inspection door 41 or 42 of structure that can be longitudinally detached, rotated, partially shifted in lateral and vertical directions, and the like, and a control panel 3 is provided opposedly to the structure of this inspection door 41 or 42. When the car 2 gets out of motion due to its failure near the lowest floor, a maintenance engineer cannot go down into a pit, but the car 2 is moved up only enough to allow the maintenance engineer to enter, and the inspection door 41 is opened from the inside of the car 2, and after operating the control panel 3 to move up the car 2, the maintenance engineer can enter into the pit and work. Since the inspection door 41 or 42 can be opened inside the car 2 to operate the control panel 3, maintenance inspection can be performed safely and easily inside the car 2 without needing to secure space for maintenance enginner to enter into the elevator shaft 1, so that there is no need to enlarge the elevator shaft 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a small elevator.

[0002]

2. Description of the Related Art Recently, elevators for middle-rise residential buildings or home elevators installed in private homes have been deregulated in accordance with the conventional Building Standard Law, and the elevator drive hoist, It is possible to install a control panel, governor, etc., set up a machine room on the side of the hoistway or on the roof of a building, install beams to support large loads, Building a building is no longer necessary. Therefore, the ratio of the elevator relation to the building is small, and the installation area has been reduced as much as possible, so that the building can be effectively used.

For this reason, small elevators, home elevators, etc., in which it is impossible to dimensionally provide a rescue exit on the ceiling as disclosed in Japanese Patent Application No. 63-56668 have been proposed.

[0004] Further, since the pit depth is shallow, it has been considered to provide a slide type inspection port on a side plate which is in contact with the front of the car on the non-operation panel side in order to inspect around the door on the lowest floor ( Japanese Utility Model Laid-Open No. 5-3279).

[0005] Further, conventionally, a pit inspection port is provided on the shaft of the hoistway, that is, on the wall as required. This structure complicates the construction of the hoistway. There were inconveniences, such as poor design, and the inability to secure the required dimensions if there were columns near the inspection door.

[0006]

However, in the prior art, the operation panel is used as a rescue exit. Its purpose is to "check around the doors of the entrance" and other specific equipment, and because of its limited slide and structure and purpose, maintenance and inspection of all equipment outside the car without increasing the size of the hoistway is required. There was a problem that I could not do it. In addition, since a part of the hoistway is used as a pit inspection port, construction of the hoistway becomes complicated. There were inconveniences, such as poor design, and the inability to secure the required dimensions for the inspection port if there were columns near the inspection port.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a structure in which a side plate of a car is detached, shifted up, down, left and right, hinged and the like is made rotatable, and the size of a hoistway is increased. In addition, maintenance and inspection of the hoisting machine control panel for the electric drive and the governor provided in the hoistway can be performed inside the car and, if necessary, outside the car.

In the present invention, the operation panel incorporated in the side plate is constructed such that the side plate of the car is moved back and forth (inside or outside of the car), shifted up and down, left and right, and rotated by a hinge or the like. Without limiting it to maintenance and inspection of certain equipment,
The maintenance and inspection of the equipment provided in the hoistway can be performed without increasing the size of the hoistway.

In this case, the side plate may be any part around the car, and the equipment to be maintained and inspected includes equipment installed in the car in addition to equipment provided in the hoistway.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

[0011] In elevators whose laws and regulations are relaxed in place of elevators based on the conventional Building Standard Law, such as middle-rise residential or home elevators, hoisting machines, control panels, etc., which are conventionally provided outside hoistways, are lifted and lowered. Can be installed in the street.

Conventionally, such an elevator has an inspection port provided on a wall around a hoistway as required, as shown in FIG. In addition, an inspection port was provided on the side plate for maintenance and inspection of specific equipment. In this structure, the construction of the hoistway becomes complicated, the design is poor, and in a home elevator or the like, a specific room adjacent to the hoistway serves as an inspection port. As shown in FIG.
If there is a pillar 6 near the entrance, it is not possible to secure a sufficient size as an inspection port (in many cases, pillars are arranged around the hoistway due to the structural structure of the building), and the inspection port is moved to a nonstandard location. There were inconveniences such as necessity. In addition, the inspection port of the car has been limited to maintenance and inspection of specific equipment.

FIG. 1 shows that the side plate 4 of the car 2 is removed back and forth (in this case, it is removed into the car 2... 41) and rotates 42. FIG. 3 shows a structure in which a part of the side plate 4 of the car 2 is vertically shifted.

For example, as shown in FIG. 1, if the control panel 3 is provided so as to face the structure of the inspection port 41 or 42 provided in the car 2, if the car 2 fails to move near the lowermost floor and the car 2 cannot move, the pit is not provided. (Not shown), but if the car has a function to raise the car 2 just as a maintenance person can put it under the car for the time being, the inspection port 41 is opened from the car and the control panel 3 is operated to operate. Just raise the car and then go into the pit and do the necessary work.

The inspection door 41 (or 42) in the car 2
) Can be opened and the control panel 3 can be operated, so that there is no need to secure a space for maintenance personnel in the hoistway 1 and maintenance and inspection can be performed safely and easily in the car 2.

In this case, it is not necessary to increase the sizes W and D of the hoistway 1.

Depending on the position and size of the inspection ports 41 to 44, a maintenance person can go out of the inspection opening 1 to the hoistway 1 to maintain and inspect not only the control panel 3 but also other devices. It is also possible to maintain and inspect the equipment provided in.

[0018]

According to the present invention, the side plates of the car can be removed from front to back, shifted up and down, left and right, and rotated by hinges, etc., so that maintenance of equipment in the hoistway is safe and easy in the car. , Can perform inspections, and if necessary, can go out of the car to perform necessary work.
