Description

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

In particular, it relates to call registration in the event of a fire.

When you operate the hall button installed at the elevator landing, the hall call is registered, and when you operate the destination floor button installed inside the car, the car call is registered.

It is well known that these calls cause elevator cars to operate.

These landing buttons and destination floor buttons (hereinafter referred to as call registration button switches) include push-type ones and contact-type ones. Suppressing type pushbuttons have been widely used in the past, and open and close contacts by utilizing the movement caused by pressing a pushbutton. In addition, contact type devices can operate without pressing a 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.

It is novel in that it operates without the need to press a button, and it has become popular among the general public.

However, the contact type one caused a building fire.

It is known that when exposed to an atmosphere of smoke or flame, the ions contained therein create the same condition as if a person had touched it, causing it to malfunction. This malfunction is extremely dangerous if the car responds to a call registered in this way and stops on the fire floor.

Will passengers be exposed to fire and burned to death? There is a danger of this.

This invention was made in view of the above-mentioned danger, and includes a first detector that operates by contact and a second detector that operates by pressure.
The first detector registers the call, and in the event of a fire, the first detector disables the call registration, and the second detector registers the call, so that even if a fire occurs, the system will not malfunction. The purpose of the present invention is to provide a button switch for call registration that never occurs.

Hereinafter, an embodiment in which the present invention is applied to a hall button will be described with reference to FIGS. 1 to 4.

In Figures 1 and 2, (1) is the landing button (inbound call).

α is a fixed conductor rod with a conductor piece (an electric wire connected to one end of IG to insulator α and IK, u9 is a socket installed in the case (3), and αe is a call registration light installed in the socket. .

In Figure 3, (A) to (C) are resistors, (2η is a field effect transistor, (C) is a diode, @(7) is a capacitor, 0υ is a transistor, C32 is an output relay, (
(to) is a fire detection relay contact that is always closed and opens when it detects a fire in the building, (b) is a DC power supply, and (to) is a bias AC power supply.

In Figure 4, (-1-) (to) is a DC power supply, (32a)

As a result, l-transistor 0υ becomes conductive, and -

The hall call registration relay (4G) is energized by the H(7) circuit and holds itself by closing the contact (40a). At the same time, the contact (Job) is also closed, the hall call registration light αe lights up, and the support (4) is illuminated to indicate that the call has been registered. When the car arrives at this floor, the car position relay contact 0D is opened, the registration relay (4Q is deenergized, and the contact (4) is
0a) (40b) are opened and the registration light σe is turned off.

Next, we will discuss the case where a fire breaks out at boarding hall 9. The fire detection relay contact @ is opened, the output relay 02 is disconnected from the power supply (b), and the first detector (7) becomes inoperable. This eliminates the need to register a landing call for a floor where a fire occurs due to a malfunction of the first detector due to water, flame, heat, etc., and it is possible to prevent a car from being called to a dangerous floor.

Furthermore, when seeking rescue, pressing the electrode plate (5) compresses the elastic body (6) and moves the electrode 49 (5a).

Its tip presses against the elastic conductive piece α. As a result, the contact point aυ comes into contact, so (g) -〇〇-+411- (4
Registration relay +40 is energized by the G- (to) circuit,
The call is registered and the registration light d is lit. The car responds to this call and is rescued.

Note that the second detector is effective both in normal times and in the event of a fire. Therefore, in normal times, the first
Even if the first detector does not operate, it is possible to register a hall call by activating the second detector, thereby avoiding the hassle of having to take off one glove.

5 and 6 show other embodiments of the invention.

In the figure (4 is the pressure-sensitive element installed at the position of the elastic body (6) in Figure 2, (40 is the second detector connected to the pressure-sensitive element by an electric wire (47), and (4 is the pressure-sensitive element) The pressure element (pressure sensitive detection circuit constructed by Monk et al., (4! Ji・Ma transistor, 60) is the output relay, and the normally open contact of the output relay group is used in place of the contact (11) in Fig. 4. .Others are the same as in FIGS. 1 to 4.

When a person touches the electrode plate (5) with bare hands, the process is similar to that already described. In addition, if the first detector is inoperable due to a fire, etc., if you apply a little more force to suppress the electrode plate (5), the pressure-sensitive detection circuit (coma) will generate a signal and the transistor (491 will become conductive). As a result, the contact corresponding to the contact tll in FIG. 4 is closed, and the registration relay (41) is energized and the 9 hall call is registered.

Although each of the above embodiments has been described as being applied to the 9th boarding hall button, it is clear that it can also be applied to the 9th row destination floor button.

As explained above, in this invention, 9 people touch the button 1
- For call registration of an elevator, comprising a first detector that operates when a button is pressed and a second detector that operates when a button is pressed, and a call registration signal is emitted when at least the first detector operates. In the case of a button switch, when a fire occurs, the first detector is made to issue one call.

This prevents the danger of erroneously registering the call for the floor where the fire occurred and calling for a car. Also, since the second detector is enabled, people seeking rescue can use this second detector to call for help. It is possible to generate a fire and evacuate using the elevator.
