JPH10316321A - Landing operation panel for elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the shock applied when a person electrified with static electricity is kept in contact with a static electricity absorbing plate by providing the static electricity absorbing plate on a face plate, and grounding the static electricity absorbing plate via very high resistance. SOLUTION: An oblong rectangular stainless static electricity absorbing plate 5 is provided via an insulating rubber of the same size below hall buttons 3, 4 on a face plate 2. When a person walks on a floor surface spread with a carpet in winter when air is dry, this human body is electrified with static electricity. The person electrified with static electricity goes to the landing of an elevator to ride it and pushes the hall button 3 or 4 to call a car to the landing. When the person touches the static electricity absorbing plate 5, the static electricity electrified to the human body is grounded to the steel frame of a building from the static electricity absorbing plate 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a landing operation panel for an elevator which is designed to ground static electricity charged on a human body without giving an impact to the human body.

[0002]

2. Description of the Related Art Conventionally, when a person walks on a floor on which a carpet is laid in a building, static electricity may be charged on the human body. Particularly in winter, when the air is dry, the human body is often charged. When a charged person touches the knob of the door, static electricity charged on the human body is grounded through the knob.

[0003]

However, if static electricity charged on the human body is grounded through a door knob or the like, the static electricity at this time becomes a large current and flows instantaneously from the human body. As a result, there is a problem that the user feels discomfort.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator hall operating panel which does not cause any discomfort to a person when static electricity charged to the human body is grounded.

[0005]

In order to achieve the above object, according to the present invention, there is provided a face plate made of an insulator, and a hole button provided on the face plate for calling a car to a landing. And a static electricity absorbing plate made of a conductor provided on the face plate, and the static electricity absorbing plate is grounded via a very high resistance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of an elevator landing operation panel according to the present invention.

In FIG. 1, reference numeral 1 denotes a landing operation panel provided at a landing of an elevator. The landing operation panel 1 has a vertically long rectangular face plate 2 made of plastic (made of an insulator). In the face plate 2,
A hole button 3 is provided for calling the car to the landing and traveling upward, and a hole button 4 for calling the car to the landing and traveling downward is provided.
Are both made of plastic.

On the face plate 2, a stainless steel (conductor) electrostatic absorbing plate 5 having a horizontally long rectangle below the hole buttons 3 and 4 has the same size as shown in FIG. It is provided via an insulating rubber 6. There is no other conductor near the electrostatic absorption plate 5.

A screw-shaped terminal 7 is welded to the back side of the static electricity absorbing plate 5, and the terminal 7 is connected to a steel frame (not shown) of the building by an electric wire 8.
A very large resistor 9 with Ω is interposed. In addition,
On the static electricity absorbing plate 5, a wording such as "A person charged with static electricity should touch this plate" may be written.

When a person walks on a carpeted floor in winter when the air is dry, the human body is charged with static electricity. A person charged with static electricity tries to get on the elevator and goes to this landing, and presses the hall buttons 3 and 4 for calling the car to the landing. At this time, when the person touches the static electricity absorbing plate 5, the static electricity charged on the human body is grounded from the static electricity absorbing plate 5 to the steel frame of the building.

Here, since there is a very large resistance 9 of 1 MΩ between the static electricity absorbing plate 5 and the steel frame of the building, the static electricity charged on the human body instantaneously becomes a large current and flows to the static electricity absorbing plate 5. Rather, the small current flows over a longer time than the instant. For this reason,
The impact received by the person touching the electrostatic absorption plate 5 is reduced. Since there is no other conductor near the electrostatic absorption plate 5, the charged static electricity is not discharged to the other conductor.

As described above, since the static electricity charged on the human body is almost grounded every time the user gets on the elevator, the impact received by this person even if he or she touches a door knob or the like is reduced. In addition,
A door knob or a car operation panel in the car may be provided with an electrostatic absorption plate.

[0013]

As described above, according to the present invention,
An electrostatic absorption plate is provided on the face plate, and the electrostatic absorption plate is grounded via a very high resistance, so that when a person charged with static electricity touches the electrostatic absorption plate, the impact received is reduced, and furthermore, the door knob Even if you touch it, the impact you receive will be reduced and you will not feel uncomfortable.
