Abstract

PROBLEM TO BE SOLVED: To obtain the call registration device for an elevator in which an unintended call is not generated, even at the operation time by the groping of a sight handicapped person. SOLUTION: A peripheral sensor 8 is provided so as to surrond a central sensor 7. Even when the central sensor 7 issues a call registration signal by contacting with a human body, at the same time, when the human body contacts to the peripheral sensor 8 and as a result, the call registration prohibition signal is issued, the supply of the call registration signal to a control board is obstructed by NAND gate 11. A projection 10 with a prescribed height is provided on the position near the central sensor 7 of the peripheral sensor 8 so as to perceive the border between the central sensor 7 and peripheral sensor 8 by a touch sense.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator call registration device provided at an elevator platform.

[0002]

2. Description of the Related Art FIG. 5 shows a schematic configuration of an elevator.
In the figure, a car 1 is driven by an electric motor 2. The operation of the motor 2 is controlled by the control panel 3, and the state of the motor 2 is monitored by the control panel 3. The weight 4 has a weight that roughly matches the weight of the car 1. Further, a call registration device 5 is provided at the elevator platform on each floor. The call registration device 5 generates a call registration signal in response to a user operation, and supplies the signal to the control panel 3. For example, when a call registration signal is issued from the call registration device 5 on the second floor when the car 1 is between the third floor and the fourth floor, the control panel 3 removes the car 1 if no other call is generated. The electric motor 2 is controlled so as to descend to the second floor.

The call registration device 5 has, for example, a configuration shown in FIG. The call registration device 5 shown in this figure is configured by buttons that do not require a stroke, that is, touch buttons. The sensing unit 6 in the figure is a member that detects a contact of a human body and generates a call registration signal, and constitutes a main part of the above-described touch button.

[0004]

Here, if the button used in the call registration device is a button that requires a certain amount of stroke and therefore has a certain degree of irregularity in the outer shape, visual impairment will occur. Even if a person touches around the sensing unit with his / her hand or finger to find the position of the sensing unit, there is little possibility that an unintended call will occur. However, in the case of a touch button having a small step with respect to the surroundings, the finger may touch the sensing unit while the visually impaired person is searching for the position of the sensing unit, as shown in FIG. This results in an unintended call, which hinders the operation of the elevator car. A similar problem can also occur, for example, when an infant suddenly gets a call near the registration device.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide an elevator call registration device in which unintended calls are less likely to occur than in the prior art.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an elevator call registration device provided at an elevator platform, which generates a call registration signal by detecting contact with a human body. A central sensing unit, a peripheral sensing unit provided surrounding the central sensing unit for detecting contact with a human body and generating a call registration prohibition signal, and a call registration signal being generated and a call registration prohibition signal being generated. A gate means for supplying a call registration signal to the control panel when the call registration signal is not present, and a gate means for preventing supply of the call registration signal to the control panel when the call registration prohibition signal is generated. Is permitted / blocked in accordance with the state of contact with the human body.

More preferably, a height between the central sensing unit and the peripheral sensing unit is high enough to be sensed by a tactile sense of a human body so as to indicate a boundary between the central sensing unit and the peripheral sensing unit. It is assumed that a projection having the following is provided. More preferably, the protrusion is provided as a part of the peripheral sensing unit.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. Note that the same or corresponding components as those of the related art shown in FIGS. 5 to 7 are denoted by the same reference numerals and description thereof is omitted.

FIG. 1 shows a configuration of a sensing unit 6A according to a preferred embodiment of the present invention. The elevator call registration device according to this embodiment has a configuration in which the sensing unit 6 in the related art shown in FIGS. 5 to 7 is replaced by a sensing unit 6A in this diagram. The sensing unit 6A has a center sensing unit 7 and a peripheral sensing unit 8 provided so as to surround the center sensing unit 7 as members that sense contact with a human body and generate an electric signal. The center sensing unit 7 has a substantially circular shape, and is electrically insulated from the peripheral sensing unit 8 by an insulator 9. Further, the peripheral sensing unit 8
Is provided with a projection 10. The protruding portion 10 is provided on the surface of the peripheral sensing portion 8 on the side of the central sensing portion 7,
It is provided so as to surround the center sensing unit 7 and indicate a boundary between the center sensing unit 7 and the peripheral sensing unit 8. Further, the protrusion 10
Is so high that it can be sensed by the tactile sense of the human body so that, for example, when a visually handicapped person gropes, it can recognize the boundary between the central sensing unit 7 and the peripheral sensing unit 8. It is said.

FIG. 2 shows a circuit for gating a signal supplied from the sensing unit 6A to the control panel 3. In this figure, the output of the central sensing unit 7 is input to the non-inverting input terminal of the NAND gate 11, and the output of the peripheral sensing unit 8 is input to the inverting input terminal. Accordingly, when the output of the peripheral sensing unit 8 is high, the output of the NAND gate 11 is low whether the output of the center sensing unit 7 is high or low. Also, if the output of the peripheral sensing unit 8 is low,
A signal having the same value as the output of the center sensing unit 7 is
Output from If the output of the central sensing unit 7 which goes high due to contact with the human body is called a call registration signal, and the output signal from the peripheral sensing unit 8 which goes high due to contact with the human body is called a call registration prohibition signal, this embodiment will be described. In the embodiment, the central sensing unit 7 causes the control panel 3
Supply of the call registration signal to the user.

Therefore, for example, when a visually impaired person tries to operate the call registration device 5 by groping and comes into contact with the central sensing unit 7 and the peripheral sensing unit 8 simultaneously as shown in FIG. Control panel 3 for call registration signal
Therefore, a call that is not intended by the visually impaired person or user does not occur. As shown in FIG. 4, if only the center sensing unit 7 is touched, a call registration signal is supplied to the control panel 3, so that the user can appropriately call the car 1 as in the related art. Further, in this embodiment, a projection 10 is provided. Therefore, when trying to operate the call registration device 5 by groping, the protrusion 10 can be recognized by touch and the position of the center sensing unit 7 can be known. Further, since the protrusion 10 is provided not on the center sensing unit 7 but on the peripheral sensing unit 8 side,
When the visually impaired seeks the position of the central sensing unit 7, the projection 10
Touching does not cause unintended calls. Also, even when an infant or the like suddenly claps his hands, the projection 10 makes it difficult for the skin to come into contact with the central sensing unit 7, and therefore, an unintended call is unlikely to occur.

In the above description, the contour of the center sensing unit 7 is circular, but the outer shapes of the center sensing unit 7, the protrusion 10, the peripheral sensing unit 8, and the sensing unit 6A are as follows.
No particular limitation is required.

[0013]

As described above, according to the present invention, the peripheral sensing unit is provided so as to surround the central sensing unit, and when the call registration prohibition signal is generated by the contact with the human body in the peripheral sensing unit, the central sensing unit is provided. Even when a call registration signal is generated due to contact with the human body at the sensing unit, this call registration signal is not supplied to the control panel, so that visually impaired persons, infants, etc. groping for the call registration device. Even if it is operated or comes into contact with it unexpectedly, unintended calls do not occur, and more accurate car operation control can be performed as compared with the related art.
