Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a button switch for registering calls such as a car call and a car call to an elevator.

When you operate the Hataba button installed in the elevator's Hataba, a Hataba call is registered, and when you operate the destination floor button installed inside the car, a car call is registered, and the elevator car is operated by these calls. This is well known.

These Habata buttons and destination floor buttons (hereinafter referred to as call registration button switches) include push-type ones and contact-type ones.

Press-type devices have been widely used in the past, and open and close contacts by utilizing the movement caused by pressing a push button. Furthermore, contact type devices can operate without pressing the button, for example by detecting the voltage induced when a human body touches the button and driving a relay. This contact type is called a touch button, etc., and is novel in that it operates without pressing a button.
It has become popular among the general public and has become quite popular.

However, these devices have low detection sensitivity, and while there is no problem when a person comes into contact with them with bare hands, they may malfunction when a person wears gloves or the like.

There are also improved versions of this, but they tend to have complicated circuits and become expensive. This invention is intended to improve the above-mentioned drawbacks, and is for elevator call registration, which comprises a composite switch that combines a contact type switch and a push type switch, so that calls can be reliably registered even when using bare hands or wearing gloves. The purpose is to provide button switches.

Hereinafter, an embodiment in which the present invention is applied to a Hataba button will be described with reference to FIGS. 1 to 4. In Figures 1 and 2,
1 is a boarding button (distinction between inbound and outbound calls is omitted), 2 is the front plate of the button, 3 is the same case, and 4 is made of transparent synthetic resin and extends through the through hole provided in the top plate 2. 5 is a button support holder having a cylindrical recess 4a in the center; 5 is one electrode plate loosely distributed in the recess 4a; 5a;
6 is an electrode shank connected to the back surface of the electrode plate 5, extending inside through the support 4 and having an insulated tip; 6 is a rubber disposed in the recess 4a between the electrode plate 5 and the bottom of the recess 4a. 7 is a first detector mounted on the case 3 and has a circuit described later in FIG. 3; 8 is an electric wire connecting the first detector 7 and the electrode rod 5a; An insulating stand 10 attached to the back has one end fixed to the insulating stand 9 and an electrode rod 5a at the center.
11 is a contact fixed to the other end of the conductor piece 10; 12 is a fixed conductor rod that is erected on an insulating stand 13 mounted on the case 3 and has a contact 11 at its tip; 14 is an electric wire connected to one end of the conductor piece 10 and reaches the insulating stand 13; 15 is a socket attached to the case 3; and 16 is a call registration light attached to the socket. In Figure 3, 20
26 is a resistor, 27 is a field effect transistor, 28 is a diode, 29 and 30 are capacitors, 31 is a transistor, 32 is an output relay, 34 is a DC power source 35 is a bias AC power source.

In Figure 4, 10 and 1 are DC power supplies, 32a is the normally open point of the output relay 32 in Figure 3, 4 rivers and Hata field call registration relays (representatively shown), and 40a and 40b are the normally open points. Contact 41 is a car position relay contact that opens when the car arrives at the floor where the Hataba call has been registered.

Now, when a person touches the electrode plate 5 with bare hands, the human body -5-8-
The bias current flows through the impedance of 8 to 27 - 35 and the ground.

This current is amplified by the field effect transistor 27, rectified and smoothed by the diode 28, the resistor 25, and the capacitors 29, 301, and then applied to the transistor 31. As a result, the transistor 31 becomes conductive, and the transistor 34-3 becomes conductive.
The output relay 32 is energized by the circuit 2-31-26-34, and the contact 32a is closed. (11) The circuit of 32a-41-40-- energizes the four Hataba call registration relays,
It is self-retained by closing the contact 40a. Contact 40 at the same time
b is also closed, the Hata field call registration light 16 lights up, and the support odor 4 is illuminated to indicate that the call has been registered. When the car arrives at this floor, the car position relay contact 41 opens,
Registration relay 40 is deenergized, contacts 40a and 40b are opened, and registration light 16 is turned off. Next, if you touch the electrode plate 5 while wearing gloves, the bias current will not flow and the first detector 7 will not operate. However, this registered light 1
6 does not light up, which indicates that the call was not registered. Therefore, when the electrode plate 5 is pressed, the elastic body 6 is compressed, the electrode rod 5a moves, and its tip presses the elastic conductive piece 10. As a result, the contacts 11 and 11 come into contact, so the registered relay 40
is energized, the call is registered, and the registration light 16 is lit. In other words, even if the detection sensitivity is insufficient due to wearing gloves, etc., the contacts 11 and 1 can be detected by applying a little more force.
The second detector consisting of 1 is activated to enable Hataba call. 5 and 6 show other embodiments of the present invention, in which 45 is a pressure sensitive element provided at the position of the elastic body 6 in FIG. 2, and 46 is connected to the pressure sensitive element by an electric wire 47. A second detector, 48 is a pressure-sensitive detection circuit composed of a pressure-sensitive element 45, etc., 49 is a transistor, 50 is an output relay,
The normally open contact of output relay 50 is used in place of contact 11 of FIG.

The rest is the same as in FIGS. 1 to 4. When a person touches the electrode plate 5 with bare hands, the process is the same as that described above.

If the detection sensitivity is insufficient because you are wearing gloves, etc., press the electrode plate 5 with a little more force, and the pressure-sensitive detection circuit 4
8 generates a signal, transistor 49 becomes conductive and output relay 50 is energized. As a result, the contact point 11 in FIG.
The corresponding contacts are opened, the four registered relays are energized, and the Hata field call is registered. Although each of the above embodiments has been described as being applied to a millstone button, it is clear that the invention can also be applied to a destination floor button.

As explained above, in this invention, a top plate made of an insulating material is attached to the button holder, and when a person touches one electrode plate fixed to the top plate, the first detector is activated. ,
When the top plate is pressed, a second detector is operated, and when at least one of the first detector and the second detector is operated, the call registration means generates a call registration signal, and Since the display is made using illumination means, the green color can be seen even with bare hands or while wearing gloves.

In particular, since the electrode plates have the same potential, they are not limited by the shape of the surface as long as they are electrically conductive. Therefore, it may be large enough to cover the entire surface of the top plate. Moreover, it is easy to operate because a call registration signal can be generated by touching a part of this large top plate. In addition, since the operation can be confirmed by display means,
If the touch button does not operate (for example, when wearing thick gloves), the second detection means can perform call registration by applying an external force.

Therefore, in normal usage, call registration is almost always done by the first detection means, and very rarely by the second detection means. The second detection means for this purpose can be expected to have a long life.
