Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator car that is equipped with an antenna for making calls using radio waves from an oscillator.

[Prior art] Conventional Utility Model Application No. 1983-61257, Utility Model Application No. 61-11
As described in Publication No. 0675 and the like, an elevator is known that is equipped with a receiving antenna so that passengers can register car calls using radio waves from transmitters carried by passengers.

[Problems to be Solved by the Invention] In conventional elevator cars, an antenna dedicated to hall registration is provided at the hall, and the hall call registration can be performed using an oscillator held by a passenger. Registration using this method was not possible.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator car in which a radio wave signal can be transmitted to an antenna within the car.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an antenna above the car, and an insulating member that prevents the flow of eddy current that cancels the magnetic flux generated by the antenna on the ceiling plate. A part of the antenna is exposed inside the car.

[Function] Since the elevator car according to the present invention is constructed as described above, the ceiling plate of the car is located at a position that vertically blocks magnetic flux caused by radio waves generated around the antenna core. uses an insulating material to prevent the flow of eddy currents that cancel out the magnetic flux generated by the antenna, and also exposes a portion of the antenna inside the car, so that radio waves transmitted from inside the car are transmitted to the car. The antenna can receive signals with good sensitivity.

[Example code] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an elevator car according to an embodiment of the present invention. The car 1 is made up of walls, the floor is made of iron plates, and the ceiling is made up of ceiling plates 2 divided by insulating members 3. An antenna 4 such as a bobbin coil antenna is arranged above the car 1, and a ceiling plate 2 and a tf! ! It is provided above the A-edge member 3. The lower end surface of the antenna core 5 of the antenna 4 is exposed inside the seat 1. Further, the receiving device 6 receives radio waves via the antenna 4 and outputs a control signal 7 for the 2'' elevator.

FIG. 2 is a perspective view of a main part of an elevator car, illustrating the magnetic flux generated by the antenna in this embodiment. A magnetic flux 8 generated around the antenna 4 passes through a portion corresponding to the insulating member 3 and reaches the inside of the seat heel 1.

FIG. 3 is an enlarged sectional view of the ceiling joint. Ceiling plates 2 adjacent to each other are insulated by an insulating member 3, and an antenna core 5 is exposed within a lighting cover 9 within the first roof panel 1.

The ceiling plate 2 is divided by an insulating member 3 to allow the magnetic flux 8 generated around the antenna 4 to reach the radio waves generated from the antenna 4, and the end face of the antenna core 5 is exposed inside the seat plate 1. Therefore, radio waves generated from inside the car seat 1 can be received with high sensitivity by the antenna 4 on the car seat 1.

Although the present embodiment has described transmitting and receiving elevator control signals, the content of the data to be transmitted and received is not limited to this, and may be other information or customer management data.

According to the above embodiment, even if the antenna 4 is installed on the car 1, it is possible to transmit and receive radio waves within the car 1, and it is also possible to send and receive radio waves to and from passengers and their luggage, who are the parties to which radio waves are sent and received. Transmission and reception is possible even if the radio waves from the device are weak.

[Effects of the Invention] As explained above, the present invention provides an antenna above the car, prevents eddy current from flowing in the ceiling plate at a position corresponding to the antenna, and cancels the magnetic flux generated by the antenna. An M edge member is provided so that the magnetic flux generated by the antenna can reach the inside of the car, and a part of the antenna is exposed inside the car, making it easy to transmit and receive data with external receiving and transmitting devices with good sensitivity. can.
