Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a call registration device in an elevator car, and more particularly to a call registration device for registering a call using a foot switch for a physically handicapped person.

[Background of the invention]

Conventionally, the call of the destination floor in the car9. The recorder is equipped with operation switches corresponding to the floors at which the elevator stops.

Calls were registered by pressing the operation switch on the desired floor.

However, in recent years, as more buildings are installing elevators and more and more welfare facilities are installing elevators, there is a growing demand for control switches that can be used by people with physical disabilities.

In particular, the installation of foot-operated switches that can be operated by people with limited mobility is increasing.

Compared to push-button switches that are operated with your fingers, foot-operated switches have a larger area, and consideration must be taken to ensure sufficient distance between switches and arrange them in a horizontal row. It becomes difficult to operate. For this reason, there were restrictions such as the number of people who could install the switch and the switch could not be installed in buildings with high floors.

In addition, selecting and pressing the appropriate foot switch from among the many foot switches installed at a part of the lower corner of the car may lead to erroneous operation.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator call registration system that allows destination calls for multiple floors to be registered with a small number of operation switches.

[Features of the invention]

The feature of the modified invention is that only one or two switches are arranged, and the destination floor is selected depending on the number of times the switch is pressed.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

Figure 1 is a car internal pressure view showing the installation location of the foot switch. In Figure 1, PLF is the floor of the car, DR is the electric door at the entrance of the car, EP is the front plate of the car, DISP indicates a foot switch panel, and DISP indicates a display panel that displays the car position, destination call registration, and the number of times the foot switch is operated. A foot switch panel FSP is installed at the bottom of the front panel near the entrance, and a display panel is placed above it to make it easier to use.

FIG. 2 is a front and side view showing details of the foot switch panel. In the figure, CFS indicates a foot switch for counting the number of operations for selecting a destination floor, and MFS indicates a foot switch for destination call uD. These switches are placed on an inclined surface to make them easier to operate.

Figure 3 is a front view showing the details of the display board. 1 This example shows the case of the 4th floor. 6 In Figure 6, IFL to 4FL indicate the car position, and IRL to 5RL indicate the destination call. An indicator light is provided to indicate the registration of the foot switch, and an indicator light is provided to indicate the number of times the foot switch is operated.

FIGS. 4 and 5 show circuit diagrams of the present invention. The present invention shows the case of four floors.

In the figure, CFS is a foot switch for counting, RFS is a foot switch for registration, C is a relay for counting, R is a relay for registration, RR is a relay for canceling counts, and IA to 4A.
is a stepping relay (1 to 4 times), IB to 3B is a stepping check relay (1 to 3 times), IR to 4R is a destination call registration relay (1st to 4th floor), IAL to 4AL is a Operation count indicator light (1 to 4 times), IRL to 4RL are destination call registration lights (1 to 4 times)
floor to 4th floor), IFL to 4FL is a car position indicator light (1st floor to
4th floor).

IF~4F base position relay (not shown) contact, OP
Symbols indicate contacts of a running relay (not shown), and ■ and ○ indicate a DC power supply. An example of registering a destination call on the third floor will be explained. When the elevator is stopped (fi (the OPx contact is open) and you step into the car and step on the CFS foot switch, relay C is turned on, and relay IA is turned on by contact C1.
is turned on and is self-held by the IAI contact. At the same time, the indicator light IAL lights up and the first stepping motion can be confirmed.

When CFS is released, relay C is released, which causes ■-R
A closed circuit of RI -I A2-Cs -I B-〇 is formed, relay IB is closed, and it is self-held by contact IBz. Next, press the CFS foot switch again ■-
RRz -Cz -IBz -3Ae-2A-〇 A closed circuit is formed, the relay 2A is turned on, and is self-held by the contact 2A1.

At the same time, the indicator light 2AL lights up, and the second stepping motion can be confirmed. Further, when the relay 2A is turned on, the contact 2Aa is opened, the relay IA is released, and the indicator light IAL goes out, indicating that the switching has been made from the first to the second. Next, when you release the CFS foot switch, it will perform the same operation as previously described, and relay C
Released, relay 2B is turned on and held. Next, three degrees CF
When the S foot switch is pressed, relay C is turned on, relay 3A is turned on and hold 2 indicator light 3AL is lit, relay 2A is released and 2 indicator light 2A is turned on.
The L light goes out and you can confirm that you stepped on it three times. Now that you have stepped through the desired steps, you need to register this as a call. To do this, use the registration foot switch RFS.
When you step on , relay R is turned on, and ■ -Rs -3Aa -
A 3Fz-3R-〇 closed circuit is formed, the relay 3R is turned on, and the call on the third floor can be registered by self-holding by the contact 3R1.

At the same time, the 1 indicator light 3RL lights up to indicate that the call on the 3rd floor has been registered. Also, by turning on relay R, relay RR
is closed, contact RR1 is opened, and all of the stepping relay and holding check relay are released to prepare for the next operation.

As explained above, by turning on the first stepping relay with the first stepping motion and releasing it, the stepping check relay is turned on, preparing for the next step, and advancing once with the first stepping motion. By repeating the process of turning on the step relay and releasing the previous step relay, the step is made to reach the desired floor, and when the destination floor is reached, the foot switch for registration is stepped on. Register the floor calls you are responsible for.

FIG. 6 shows another embodiment of the invention. The opening switch is equipped with only one CFS for counting, and the call registration is performed after a certain period of time (about 2 to 3 seconds) after the first stepping operation. A timer T circuit is added, and the closing command contact of relay R is changed from RFS to a timer T contact. The operation starts when the first step relay is turned on, and timer T starts counting. When the set time is reached, relay R is activated by the TI contact.
and register the call.

Although this embodiment has the advantage of being configured with only one foot switch, it has the disadvantage that there is often a pause after the registration is completed, making the user feel a little uneasy.

[Effects of this project]

According to the present invention, it is possible to register calls on multiple floors using one or two operation switches, and it is possible to provide an economical call registration device that does not cause erroneous presses.
