Abstract

A touch panel is often used for an operation panel which is provided in the elevator hall or car and the user registers the destination floor. However, since the touch panel is operated by pushing or touching the flat surface, the operation feeling is poor. The operation switch of the present invention is provided with a key top having a marking character formed on the top surface, and a conductive layer formed on the front and back surfaces of the substrate and insulated from each other, and a conducting means for conducting the conductive layer. Therefore, it is possible to obtain a feeling of operation while being touch type.

Description

The present invention relates to an operation switch used in an elevator control panel.

  An operation panel is provided in the elevator hall or in a car, and a user presses an operation button to register a destination floor, but in recent years, an operation panel using a touch panel has often been used. Since the touch panel simply presses or touches a displayed flat surface such as a destination floor, the operation feeling is poor. For this reason, there has been proposed a control panel that can be appropriately performed with the click feeling of the touch operation on the touch panel (for example, Patent Document 1).

Patent document 1 is equipped with the display cover which has the press operation part which has the dome shape protruded on the surface of the panel display comprised with the touch panel. The pressing operation unit is reversed by the pressing operation to perform a contact operation with the dent touch panel.

Patent Document 1: JP-A-2005-82299 (FIG. 2)

  According to Patent Document 1, an operation can be performed with a click feeling. However, since the touch operation unit is provided on the touch panel, the configuration is complicated.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an operation switch that can be operated while having an operation feeling by touching with a simple configuration.
Another object of the present invention is to realize an operation switch that can give a click feeling by pressing the key top of the operation switch while touching it, and also considering a visually impaired person.

  In the operation switch of the elevator according to the present invention, the indicator is formed in a convex shape on the top surface, and the conductive layer is electrically connected to the key top on which the conductive layers insulated from each other are formed on the front and back surfaces of the substrate. And a conducting means.

  Further, the marking character is formed in a concave shape following the convex shape of the top surface.

  According to the present invention, the switch can be operated by touching the key top on which the indication character is formed. Also, by pressing the key top, a click feeling can be obtained.

It is a control panel using the operation switch of Embodiment 1 of this invention. It is a key top of the operation switch of Embodiment 1 of this invention. Sectional drawing in alignment with the III-III line of FIG. Sectional drawing in alignment with the IV-IV line of FIG.

  Hereinafter, the details of the present invention will be described using the above-described drawings.

Embodiment 1
1 to 4 are diagrams for explaining the first embodiment of the present invention. In the drawings, the same reference numerals indicate the same components, and the description thereof will be omitted.
FIG. 1 shows an operation panel 1 on which the operation switch of the present invention is arranged. The control panel 1 is installed in a car or at a landing. The operation panel 1 has a cover 3 covering a box 3 containing various devices. The front panel 2 is provided with a display 4 for displaying a destination floor or information, a destination floor registration button 5 for registering a call, and a door open / close button 6 for opening / closing a door. Reference numeral 7 is a key top of the destination floor registration button 5.

The key top 7 used for the destination floor registration button 5 is shown in FIG. In the key top 7, a pressing surface 7b protrudes from a base portion 7a. The base portion 7a and the pressing surface 7b are connected by an inclined surface 7c. Further, marking characters 7d are formed on the pressing surface 7b. The mark letters 7d are numbers or the like representing the floor, and protrude from the pressing surface 7b.

FIG. 3 shows a cross-sectional view of the key top 7. FIG. 3A is a cross section of the key top 7 along the line III-III in FIG. Further, as shown in an enlarged view of a portion A in FIG. 3A in FIG. 3B, both surfaces of the base material 8 are covered with a conductive layer 9. The base 8 of the key top 7 is made of a thermoplastic resin material. Specifically, polycarbonate, polypropylene, ABS, polyethylene, polystyrene, PET and the like are materials which do not have conductivity. The back side of the inscription character 7 d is also recessed, and the thickness of the inscription character 7 d portion is formed to the same thickness as the substrate 8. The conductive layer 9 is formed by sticking or integrally molding a conductive polymer, a copper foil, a conductive fiber or the like. The conductive layer 9 is formed on both the back and the front of the substrate 8, and the front and the back are insulated.

FIG. 4 shows a cross-sectional view of the destination floor registration button 5 along the line IV-IV of FIG. The upper side of FIG. 4 is an operation side on which the display unit 4 and the like of the operation panel 1 are disposed, and the lower side is a box 3.

The key top 7 is inserted into the hole 2 a provided for the destination floor registration button 5 of the front plate 2 from the box 3 side. The switch substrate 11 sandwiches the base 7 a of the key top 7. The switch substrate 11 is fixed to the front plate 2 via the fixing tool 12.

An electrode 13 serving as a conducting means is provided between the base 7 a of the key top 7 and the front plate 2. A measuring device not shown that changes the electrostatic capacitance when a human finger touches the indication character 7 d of the key top 7 by applying a voltage to the electrode 13 to generate a uniform low voltage electric field on the key top 7 surface It measures and detects that it was operated by. This is similarly detected on the pressing surface 7b or the inclined surface 7c. By this detection, the key top 7 is switched on.

Further, on the switch substrate 11, a fixed contact 14 which is a conducting means is disposed at a position facing the pressing surface 7 b of the key top 7.

When the mark 7d of the key top 7 and the pressing surface 7b are pressed in the direction of the arrow B, the key top 7 is deformed toward the fixed contact 14 side, so the pressing surface 7b contacts the fixed contact 14 and a circuit not shown opens or closes. . As a result, the key top 7 is switched on.

Note that the key top 7 may be touched to indicate by voice that the switch is turned on. Then, when the wrong key top 7 is touched, the key top 7 may be reselected.

According to the first embodiment, the following effects can be obtained.
The operation switch of the elevator according to the present invention has the key top 7 in which the indication characters 7d are formed in a convex shape on the top surface 7b and the conductive layers 9 which are mutually insulated on the front and back surfaces of the base material 8; Since the conductive layer 9 is provided with conductive means, when the key top 7 on which the indication character 7 d is formed is touched, the conductive means can be made conductive and the switch can be operated. That is, since it can be used as a touch button, it can be operated while having an operational feeling.

Furthermore, since the marking character 7d is formed in a concave shape following the convex shape of the top surface 7b, the key top can obtain a click feeling by crushing the hollow portion when pressed. It is possible to realize an operation switch that also takes into consideration visually impaired persons.

Since the base material 8 uses a thermoplastic resin material, various shapes can be easily made inexpensively by a processing method such as vacuum molding.

5 destination floor registration button, 7 key top, 7a base, 7b top surface, 7c inclined surface, 7d marking characters, 8 base materials, 9 conductive layers, 11 switch boards, 12 fixtures, 13 electrodes, 14 fixed contacts.
