Mode for carrying out the invention
[0015]
　Hereinafter, embodiments of the present invention will be described with reference to the following Examples 1 and 2 with reference to the drawings.
[0016]
　In each figure, those having the same reference number indicate the same configuration requirements or configuration requirements having similar functions.
Example 1
[0017]
　FIG. 1 is a schematic view of a car in an elevator according to a first embodiment of the present invention. FIG. 1 is a view when the car door is viewed from inside the car.
[0018]
　As shown in FIG. 1, the car 1 is provided on the floor 2, the side plate 3 erected on the peripheral edge of the floor 2, and the ceiling 4 provided on the upper part of the side plate 3 and the design panel 4A is arranged on the cab side. And a car door 5 facing the landing side.
[0019]
　The car 1 is driven by a known drive mechanism and moves up and down in a hoistway in a building structure. Further, the car door 5 engages with a landing door (not shown) when the car 1 lands, and is opened and closed together with the landing door by a known door drive mechanism provided in the car 1.
[0020]
　The car 1 is provided with a hearing aid system 10 having an induction loop, which will be described later. The hearing aid system 10 includes a magnetic induction amplifier 11 that amplifies an audio signal output by a control unit (not shown) and outputs an audio signal current, and an induction loop 12 connected to the output of the magnetic induction amplifier 11. The induction loop 12 is arranged outside the car 1 on the upper side of the ceiling 4 in a loop shape along the peripheral edge of the ceiling 4. As a result, a magnetic field can be generated in the entire car 1, and the induction loop 12 can be easily installed and maintained.
[0021]
　The magnetic induction amplifier 11 may amplify an audio signal which is an acoustic signal for transmitting information to an elevator user in words such as a guidance broadcast, or an acoustic signal for transmitting information by an alarm or a melody. Good.
[0022]
　When the voice signal current output from the magnetic induction amplifier 11 flows through the induction loop 12, a magnetic field that changes according to the voice signal is generated in the car 1. This magnetic field induces a weak current in the induction coil of the receiver carried or worn by the elevator user in the car 1. The receiver amplifies this weak current and reproduces the audio signal. As a result, the elevator user can clearly hear the contents of the broadcast in the car 1 and the contents of the call made through the intercom in an emergency by using the earphones provided in the receiver.
[0023]
　Next, the configuration of the induction loop 12 will be described.
[0024]
　FIG. 2 shows the configuration of the induction loop arranged on the ceiling 4 in the first embodiment.
[0025]
　In the induction loop 12, a plurality of wire harnesses (hereinafter, referred to as “harnesses”) composed of electric wires such as insulating coated conductive wires and connectors are connected to each other by connectors. As a result, the wires form a single or multiple (double in FIG. 2) loop.
[0026]
　As shown in FIG. 2, the induction loop 12 is composed of a branch harness 20 serving as a connection portion to the output of the magnetic induction amplifier 11, a long standard harness 30 having a predetermined length dimension, and a standard harness. It is composed of a long adjusting harness 40 having a short length dimension. In the first embodiment, one, three, and one branch harness 20, standard length harness 30, and adjustment harness 40 are used, respectively.
[0027]
　The branch harness 20 includes a first connector 21, a second connector 22, and a third connector 23, and the first connector 21 is connected to the magnetic induction amplifier 11. Each of the three standard harnesses 30 (30A, 30B, 30C) includes a fourth connector 31 and a fifth connector 32. The adjustment harness 40 includes a sixth connector 41 and a seventh connector 42.
[0028]
　The second connector 22 of the branch harness 20 and the fourth connector 31 of the first standard length harness 30A are detachably fitted and engaged with each other. The fifth connector 32 of the first standard length harness 30A and the fourth connector 31 of the second standard length harness 30B are detachably fitted and engaged with each other.

The induction loop 12 configured in this way is connected to the magnetic induction amplifier 11 via the first connector 21 of the branch harness 20.
[0029]
　The adjustment harness 40 may be connected between the branch harness 20 and the standard length harness as shown in FIG. 2, or may be connected between two adjacent standard length harnesses 30.
[0030]
　In the induction loop 12 shown in FIG. 2, an electric wire is wound around the peripheral edge of the ceiling 4 over two turns. Therefore, as will be described later, two electric wires are electrically connected to each of the connectors included in the branch harness 20, the standard length harness 30, and the adjustment harness 40.
[0031]
　The number of standard length harnesses 30 is not limited to three, and is appropriately set according to the size of the car 1, that is, the size of the ceiling 4. Further, when the adjustment harness 40 cannot satisfy the desired loop length with respect to the size of the ceiling 4 by one or a plurality of standard length harnesses 30, the adjustment harness 40 makes up for the shortage. Therefore, the length of the adjusting harness 40 is appropriately adjusted according to the size of the ceiling and the number of standard harnesses. If the desired loop length can be satisfied by one or more standard harnesses 30, the adjustment harness 40 may not be used.

Here, the loop on the first lap and the loop on the second lap are electrically connected by the electric wire 51B in the branch harness 20. As a result, an induction loop 12 composed of two consecutive loops is formed.

Therefore, the time required for laying the induction loop can be shortened. Further, by manufacturing the wire harness before the laying work, it is possible to shorten the time and cost of the laying work of the induction loop 12.

　Further, according to the first embodiment, by using a branch harness, a standard length harness having a predetermined length, and an adjustment harness shorter than the standard length harness, it is possible to set the loop length according to the size of various cars. .. For example, by adjusting the number of standard-length harnesses and adjusting the length of the adjustment harness, it is possible to handle ceilings of different sizes, and the application design of the induction loop becomes easy.
