JPH06271205A - Control device for elevator - Google Patents

Abstract

PURPOSE:To enhance the designing effect by controlling lighting order of a plurality of illumination lamps, arranged in the exterior of an elevator, so as to change in accordance with an operating direction of the elevator, in the observation elevator visible from the outside. CONSTITUTION:An observation elevator car 10 has a car inner room 11, to also provide exterior lighting (illumination) lamps 1L, 1R, 2L2R to NL, NR, and the car 10 is connected to a balance weight 16 through a hoist 15 in a manner of well bucket and lifted by actuating a motor 14. Here is changed lighting order of the lamps 1L, 1R, 2L2R to NL, NR in accordance with an operating direction of an elevator. That is, lighting is controlled in such a manner that at the time of up lift operation, the lamp is successively lighted from the lamps 1L, 1R set up in the bottom part to the lamps NL, NR in the uppermost position, next cyclically similarly lighted from the lamps 1L, 1R, and at the time of down lift operation, the lamp is lighted in a reverse direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an elevator, and more particularly to a control device suitable for effectively producing illumination of a prospective elevator.

[0002]

2. Description of the Related Art Japanese Utility Model Application Laid-Open No. 56-62374 discloses an example of an elevator for observation, in which illumination in a car is reduced in illuminance depending on the position of the elevator.

Further, regarding the illumination, it is disclosed in
Japanese Patent Laid-Open No. 3-106786 describes turning off the illumination under certain conditions.

[0004]

Although the above-mentioned known examples describe the in-cage lighting of a view elevator,
The exterior lighting of recent elevators is luxurious, and it is also expected to have a staging effect.

An object of the present invention is to provide a control device that enhances the effect of the illumination of a prospective elevator in a simple manner.

[0006]

To achieve the above object, the present invention provides a logic including an illumination lamp mounted on the exterior of a prospective elevator, a transistor for driving each lamp, and a drive circuit for driving the transistor. And an elevator control device.

[0007]

[Operation] The elevator car is raised by the control device,
The descent operation is performed, and the illumination can be turned on and off by the power supply and the transistor in the control device.

Now, considering the ascending operation, when the ascending operation is performed, the transistors of the control device are driven so that the respective lamps of the illumination are sequentially turned on from the lamps installed at the lower part to the upper part. By doing so, the effect of the rise of the elevator can be exerted for those who are watching from the outside.

Similarly, in the descending operation, the design effect is improved by sequentially lighting the illumination lamps from the upper part to the lower part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The observation elevator car 10 includes a car interior 11 and an exterior illumination (illumination) lamp 1L,
It is composed of 1R, 2L, 2R to NL, NR, and enhances its fashionability by looking at the elevator from the outside. The car 10 is arranged in the form of a balance with the counterweight 16 via the hoisting machine 15, and is lifted and lowered by the motor 14. Illuminated lamps 1L, 1
R to NL and NR are mobile cables 12 dedicated to elevators
Is connected to the controller 13.

Now, let us consider the time when the elevator is operating in an ascending manner. In the same direction as the driving direction of the elevator, the illumination lamps are sequentially turned on from the lamps 1L and 1R installed at the bottom to the uppermost NL,
It lights up to NR, and then cyclically lights up from 1L and 1R as well.

FIG. 2 shows this lighting circuit and its logic.
Shown in. FIG. 2 (a) is a circuit diagram thereof, showing lamps 1L and 1R.
Are connected in parallel, 2L and 2R are connected in parallel ... NL and NR are connected in parallel, and transistors TRS ₁ and TRS _{2 to} TR are respectively connected.
Each lamp can be turned on by S _N. Figure 2
(B) is a time chart showing the operation of the base signals B ₁ , B ₂ ... B _N of the respective transistors in (a). By turning on the bases of the transistors _{cyclically in} the order of B ₁ , B ₂ ... B _N as shown in FIG. 2B, the illumination lamp is lit from bottom to top. On the other hand, when the elevator is in the descending operation, the order of the base signals is reversed and the lights are turned on in the order of B _N ... B ₂ , B ₁ , the illumination is in the same direction as that of the elevator, that is,
The lights turn on in the downward direction.

[0013]

According to the present invention, the illumination lamps are sequentially turned on according to the driving direction of the elevator, and the design effect is enhanced.
