Abstract

PURPOSE: To secure safety of a passenger in a simple structure by judging positional dislocation of a cage doorsil against a platform doorsil in accordance with a detection signal from a car position detection means and driving an alarming means at the time of judging it as positional dislocation. CONSTITUTION: A positional dislocation judging means 21 compares a specified value within previously set tolerance and a step difference ΔS with each other, and when ΔS exceeds the specified value, it outputs a positional dislocation judging signal E. Consequently, an alarm driving means 22 drives an alarming means 23 by outputting an alarm driving signal F, and a lighting system 14 to be the alarming means irradiates alarm light L upward from a groove 13 of a cage doorsil 12. In the case when a cage 2 stops with its floor surface dislocated from a position of a platform stop line S in this way, the alarm light L is irradiated toward upward from the inside of the groove 13 of the cage doorsil 12 while opening a door, and by making a passenger recognize that there is the step difference ΔS between a floor surface of a platform 1 and the floor surface of the cage 2 by attracting an attention of the passenger to his steps, it is possible to let the passenger safely get on and off the cage 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car position alarm device that can easily alert passengers during boarding / alighting when there is a displacement between the carousel sill and the car sill when the car is stopped. It is a thing.

[0002]

2. Description of the Related Art FIG. 4 is a plan sectional view showing a conventional elevator apparatus, and FIG. 5 is a sectional view taken along line BB in FIG.
In the figure, 1 is a hall, 2 is a basket, 3 is a hoistway for raising and lowering the basket 2, 11 is a hall sill provided at the entrance / exit side of the hall 1, and 12 is provided at the entrance / exit side of the basket 2. The car sill, S is the landing stop line at which the car sill 12 should stop at normal times, and ΔS is the step between the landing stop line S and the car sill 12 (floor surface of the car 2) caused by the displacement of the stop position of the car 2.

Next, the operation of the conventional elevator apparatus shown in FIGS. 4 and 5 will be described. The car 2 is driven up and down along the hoistway 3 and stops at the landing 1 where the call is registered. Normally, the plane position of the car sill 12 is the landing sill 1.
It stops so as to coincide with the hall stop line S of 1.

However, due to some trouble, as shown in FIG.
There may be a case where the plane position of the car threshold 12 does not coincide with the landing stop line S. When the stop position of the car 2 deviates from the landing stop line S in this way, unless the passenger is alerted to the step ΔS, the passenger may fall and get into an unexpected accident when getting on and off. Therefore, various measures are being taken in order to notify the passenger of the occurrence of the step ΔS, but there is a possibility of causing a large cost increase such as a large scale alarm device.

[0005]

As described above, the conventional elevator apparatus is not provided with a device that easily warns the occurrence of the position shift of the car 2 when the stop position of the car 2 deviates from the landing stop line S. Therefore, the step ΔS between the floor surface of the hall 1 and the floor surface of the basket 2 prevents an accident such as a passenger falling while getting on and off, which causes a problem of cost increase.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain an elevator car position alarm device which can ensure passenger safety with a simple structure.

[0007]

An elevator car position alarm device according to claim 1 of the present invention is a car driven along a hoistway, a landing place where the car is positioned and stopped, and a car for the landing place. A cage position detecting means for detecting a position, a position deviation determining means for determining a position deviation of the basket sill with respect to a hall threshold based on a detection signal from the basket position detecting means, and a position deviation determining means for determining a position deviation. And an alarm means to be driven.

Further, the elevator car position alarm device according to claim 2 of the present invention is the elevator position alarm device according to claim 1, wherein the alarm means comprises an illuminating device provided in the groove of the basket sill. When it is determined that the position of the vehicle is displaced, the warning light is emitted upward from the cage threshold.

[0009]

According to the first aspect of the present invention, when a displacement occurs between the landing sill and the car sill when the car is stopped, the alarm means is driven to notify the passengers getting on and off the step. Call attention.

Further, according to a second aspect of the present invention, when a position displacement occurs when the car is stopped, the warning light is emitted upward from inside the groove of the car sill, so that the passengers getting on and off the step Call attention.

A translucent cover 16 is a case for positioning and mounting the lighting device 14.

Reference numeral 17 denotes a light projecting portion provided on the side wall of the basket 2 for projecting detection light to the hall 1 side, and reference numeral 18 denotes a light receiving portion for receiving the detection light reflected from the hall 1 side. These are photocouplers. Is composed of an optical sensor. Reference numeral 19 is a stop position indicator provided on the side wall of the hall 1 and irradiated with the detection light from the light projecting unit 17, and is provided with a scale indicating the relative position with respect to the car 2, for example. The above photo coupler 17,
18 and the stop position designating unit 19 constitute a car position detecting means 20 for detecting the position of the car 2 with respect to the hall 1.

The illuminating device 14 constitutes an alarm means and is selectively driven by an alarm control device which will be described later. Further, the basket position detecting means 20 may be, for example, Japanese Patent Laid-Open No.
As described in Japanese Patent Publication No. 294180, it may be configured by known means.

FIG. 3 is a functional block diagram showing an alarm driving device for driving the illuminating device 14, and 21 is a hall threshold 11 based on a detection signal D from the car position detecting means 20.
The position shift determining means for determining the position shift of the car threshold 12 with respect to the, the alarm driving means 22 for outputting the alarm drive signal F in response to the position shift determining signal E from the position shift determining means 21, and 23 the position shift determining means. Reference numeral 21 is an alarm means that is driven by an alarm drive signal F when a displacement is determined. The alarm means 23 is composed of, for example, the lighting device 14.

By illuminating the warning light L upward from the inside of the groove 13 of the passenger, and recognizing that there is a step ΔS between the floor surface of the hall 1 and the floor surface of the basket 2 by directing the passenger's attention toward the feet, Passengers can safely get on and off the car 2.

Usually, passengers see their feet when getting on and off,
The warning light L can be easily recognized, and therefore, the step ΔS at the entrance / exit can be reliably recognized. Further, since the lighting device 14 is provided in the groove 13 of the basket sill 12 as the warning means 23, there is no particular need for space and there is no obstacle to passengers getting on and off.

Example 2. In the first embodiment, only the lighting device 14 is used as the warning means 23, but not only the lighting device 14 but also a buzzer or an automatic announcement may be used in combination. In this case, the step difference Δ
Since the occurrence of S can be recognized, the safety of passengers can be further improved.

Example 3. Further, as the car position detecting means 20, an optical sensor including the photocouplers 17 and 18, and a stop position indicating section 19 arranged so as to face the optical sensor.
Although and are used, any other known means can be applied. For example, when a mechanical switch that operates within the allowable range of the step difference ΔS is used, the calculation function of the positional deviation determination means 21 can be omitted.
