Is a hinged door, in which the hinged door 4 is closed and partially broken. Usually, the surface of the switch box 3 is covered with the hinged door 4 so that general passengers, such as managers, do not touch the maintenance inspection switches 6l to 6q. In the present embodiment, only the maintenance / inspection switches 6l to 6q operated by the maintenance / inspection operator during the maintenance / inspection work are mounted in the switch box 3.
[0014]
Reference numeral 7 denotes a key switch provided in the part of the hinged door 4 on the face of the face plate 1. In the case of an administrator's operation, the key switch 7 functions as an administrator switch by rotating an inserted administrator key as a first key only in one direction. Further, in the case of maintenance / inspection operation, the key switch 7 rotates the maintenance-inspector-dedicated key as the inserted second key in the direction opposite to the administrator-dedicated key, and the maintenance-inspector-dedicated key The hinged door 4 is opened, and the maintenance inspection switches 6l to 6q in the hinged door 4 can be operated. If desired, the key switch 7 functions so that the second key for maintenance and inspection can be rotated in the same direction as the first key.
[0015]
FIG. 2 is a diagram showing details of the key switch.
In the figure, 7a to 7g are notch positions and unlocking positions of the key switch 7, 8a is a rotation direction of a key that can be operated by an administrator, and 8b is a rotation direction of a key for opening the hinged door 4. . For example, if the position of the notch position a of the key switch 7 is paused, the position of the notch position a is operated, the position of the notch position c is illuminated, and the position of the notch position d is a fan, the manager uses the key for the manager as a key When the switch is inserted into the switch 7, the key is rotated in the rotational direction 8a and stopped at the position of the notch position a, the elevator is changed from the rest state to the operation state. Further, when the key is rotated to the position of the notch position c, the illumination in the car is turned on. Further, when the key is further rotated to the position of the notch position d, the fan in the car operates.
[0016]
In this way, the manager can perform a predetermined operation of the elevator by operating the key switch 7 with the manager-dedicated key. Note that with the administrator-only key, the rotation direction of the key is limited only to the rotation direction 8a, and the hinged door 4 cannot be opened by rotating the key in the rotation direction 8b.
[0017]
On the other hand, the maintenance / inspection operator operates the predetermined maintenance / inspection switch by rotating the key in the rotation direction 8b to open the hinged door 4 using the maintenance / inspection operator dedicated key.
In addition, the dedicated key for maintenance / inspection workers may be configured so that the rotation direction of the key can be rotated in both directions of the rotation directions 8a and 8b as necessary. The key switch 7 whose contact changes and the rotation key for locking the switch box 3 have a function of being substantially combined.
[0018]
In this way, in this embodiment, the manager switch operated by the manager can be rotated from the insertion position to the notch position corresponding to the management operation in the key switch mounted on the face plate surface. Elevator operation is possible.
On the other hand, a maintenance / inspection switch operated by a maintenance / inspection operator is mounted on a switch box in a hinged door that is unlocked only by a different key although it is the same key switch. By doing so, the administrator switch and the maintenance inspection switch can be separated to prevent erroneous operation by the administrator, enabling smooth operation of the elevator and keeping the administrator in the car. This eliminates the need for an engineer in charge of maintenance and inspection.
[0019]
Embodiment 2. FIG.
FIG. 3 is a diagram showing details of key switches in the elevator car operation panel according to the second embodiment of the present invention. 3, the same parts as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted.
In the figure, reference numerals 9a to 9e are indicator lamps as display means for informing that the operation mode corresponding to each notch position of the key switch 7 has been reached. These indicator lamps 9a to 9e are not shown in FIG. For example, it is provided around the key switch 7 of FIG. 1 at intervals of a predetermined angle.
[0020]
When the manager inserts a key for the manager into the key switch 7, rotates the key in the rotation direction 8a, and stops at the position of the notch position a, the elevator enters an operating state. At this time, the indicator lamp 9a is turned on to notify the manager that the elevator is in an operating state. Further, when the key is rotated in the rotation direction 8a and stopped at the notch position c, the indicator light 9b is turned on to notify that the illumination in the car is turned on. Further, when the key is rotated and stopped at the position of the notch position d, the indicator light 9c is turned on to inform that the fan in the car has been operated. As described above, when the administrator rotates the administrator-specific key in the direction of the rotation direction 8a and the predetermined function is in the operating state, each of the indicator lights 9a to 9c can be turned on to inform the administrator of the operating state.
[0021]
In this way, in this embodiment, the manager rotates the key in the direction of the rotation direction 8a with the key for the manager, and when a predetermined function is in the operating state, each indicator lamp is turned on, and the key switch The manager can be notified of the operating state, which helps to prevent erroneous operation of each operation switch by the manager.
