Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator car, and particularly to an elevator car suitable for transmitting and receiving wireless signals within the elevator car.

[Conventional technology]

Generally, an elevator car is equipped with a floor plate covering the lower part, a side plate and a door installed on the sides of this floor plate, and a ceiling placed above the side plate and door. , at least one of the ceilings is provided with an electrically conductive portion. For example, as a device for performing wireless communication from inside the elevator car to the outside,
As shown in Publication No. 235375, an antenna is provided near the elevator hall, and this antenna captures a radio signal emitted by a transmitter inside the elevator car, and a receiving device connected to the antenna receives the signal from the elevator car. It is suggested that something be done.

[The problem that the idea attempts to solve]

By the way, in the case of the above-mentioned conventional technology,
The radio waves between the inside of the elevator car and the external antenna are
There has been a problem in that it is difficult to transmit and receive wireless signals within the elevator car because they are often blocked by the floorboards, side panels, doors, ceilings, etc. of the elevator car.

This invention consists of a floor plate that covers the inside of an elevator car,
To provide an elevator car capable of transmitting and receiving radio signals inside the car through any one of a side plate, a door, and a ceiling.

[Means to solve the problem]

To achieve this purpose, the present invention provides at least one of the floorboards, side panels, doors, and ceilings covering the interior.
In an elevator car equipped with a conductive part,
A transmitting/receiving device for transmitting and receiving wireless signals is provided outside the elevator car, and an insulator is attached to the conductive portion to insulate the conductive portion from the surroundings, and the conductive portion and the transmitting/receiving device are connected to each other. The configuration includes signal lines for

[Effect]

Since the present invention is configured as described above, when a wireless signal is emitted within the elevator car, this wireless signal is captured by the conductive part of the elevator car and is received by the external transmitting/receiving device via the signal line. . At this time, the conductive portion is insulated from the surroundings by an insulator, and the signal current flowing through the conductive portion is prevented from attenuating. Similarly,
Signals emitted by an external transmitter/receiver are sent via a signal line to a conductive part of the elevator car, and emitted from this conductor as a wireless signal. Therefore, this wireless signal is received by a receiver inside the elevator car.

As a result, wireless signals can be transmitted and received inside the elevator car through any one of the floorboards, side panels, doors, ceiling, etc. that cover the inside of the elevator car.

〔Example〕

Hereinafter, the elevator car of the present invention will be explained based on the drawings.

1 and 2 are explanatory diagrams showing one embodiment of the elevator car of the present invention, and FIG. 1 is a longitudinal sectional view;
FIG. 2 is a perspective view.

The elevator car 1 shown in FIG.
a, 3b and door 4, and these side plates 3a, 3b
and a ceiling 5 placed above the door 4. And these floor boards 2, side boards 3
A, 3b, the door 4, the ceiling 5, etc., at least one, for example, the side plate 3a, is provided with a conductive part 6. An insulator 7 is installed to insulate from. Further, one end of a signal line 8 is connected to the conductive portion 4 of the side plate 3a, and the other end of this signal line 8 is connected to a transceiver 9 for transmitting and receiving data to and from the elevator car 1.

In this embodiment, when a passenger 11 in the elevator car 1 shown in FIG. It is received by a transceiver 9 via line 8 . Therefore, this transceiver 9 is
For example, a control device (not shown) may include elevator car 1.
It is also possible to issue control signals. On the other hand, transmission from the transceiver 9 into the elevator car 1 is carried out by sending the signal output from the transceiver 9 to the conductive part 6 of the side plate 3a via the signal line 8, and emitting it as a wireless signal from the conductive part 6. It is done. The wireless signal from this conductive portion 6 is received by a receiver (not shown). Note that due to the insulator 7, the side plate 3
Attenuation of the signal current flowing through the conductive portion 6 of a is prevented.

In the embodiment configured in this way, the interior of the elevator car 1 can be accessed through any one of the floor plate 2, side plates 3a, 3b, door 4, ceiling 5, etc. that cover the inside of the elevator car 1, for example, the side plate 3a. It is possible to send and receive wireless signals. In addition, compared to conventional devices installed in halls, etc., the side plate 3a etc. are installed closer to the transmitter 12 etc. inside the elevator car 1, so weaker radio signals can be transmitted and received with the inside of the elevator car 1. can be done. Furthermore, compared to the case where an antenna is newly installed inside the elevator car 1, this antenna does not cause deterioration in design, and the side plate 3a
Since only the new insulator 7 is installed, there is no increase in costs due to an increase in the number of parts such as antennas.

In this embodiment, a case has been described in which the transmitter/receiver 9 outputs a control signal for the elevator car 1, but the types of wireless signals transmitted and received within the elevator car 1 are not limited to this, and may be used to transmit or receive other personal information or passenger management information. It may also be data.

Further, in this embodiment, the conductive part 6 of the side plate 3a is used as the antenna part of the transmitter/receiver 9, but instead of this side plate 3a, it can be attached to the floor plate 2, the door 4, the ceiling 5, or the ceiling 5. Any of the lighting cover frame (not shown), ventilation fan frame (not shown), etc., which has a conductive part, can be used as the antenna part of the transceiver 9. Furthermore, in this embodiment, a transmitter/receiver 9 is provided outside the elevator car 1, but instead of this transmitter/receiver 9,
If necessary, a transmitter that only transmits or a receiver that only receives can be provided.

[Effect of idea]

Since the present invention is configured as described above, it is possible to transmit and receive wireless signals inside the elevator car via any one of the floorboards, side panels, doors, ceiling, etc. provided inside the elevator car. . Therefore, there is an effect that communication between the inside and outside of the elevator car can be carried out reliably and easily using a receiver or a transmitter carried into the elevator car along with passengers or luggage.
