Description

[Detailed Description of the Invention] This invention relates to a device for making an existing telephone wireless, which can answer telephone calls at a location remote from the telephone.

Since commonly used telephones are wired, they cannot be carried anywhere, and each time a call is made, the user must go to the telephone, pick up the handset, and answer the telephone, which is a hassle. There are also wireless telephones, but they are not common because the equipment and call charges are expensive, and they are quite heavy, so they are good for installing in cars, but they are inconvenient to carry. be.

This invention has been made in view of the above circumstances, and aims to provide an existing telephone wireless device that can answer telephone calls at a location away from the telephone and is convenient to carry.

This invention will be described below based on embodiments shown in the accompanying drawings.

As shown in the figure, a telephone set 1 is provided with a placing part 3 on which a handset 2 is placed, and a pair of switch switches 4, 4, which are activated when the handset 2 is attached or removed, are attached to the placing part 3. There is.

An engaging part 6 that engages with the placing part 3 is provided at the lower part of the radio main body 5 placed on the above-mentioned placing part 3, and the above-mentioned hook switches 4 are protruded into the engaging part 6. A pair of holes 7, 7 are formed.
A movable means 8 for controlling on/off at least one of the hook switches 4 protruding from the hole 7 is provided inside the radio main body 5. This movable means 8 consists of, for example, a solenoid 9 and a movable iron core 10. When the solenoid 9 is energized, the movable iron core 10 is raised by the generated magnetic field and the switch 4 is turned on, and when the solenoid 9 is de-energized, the solenoid 9 No magnetic field is generated, the movable iron core 9 descends due to its own weight, and the switch 4 is turned off.

Further, a handset 2 is mounted on the top of the radio main body 5.
A placing part 11 for placing the handset 2 is provided in the same manner as the placing part 3 of the telephone 1, and this placing part 11 is provided with a switch means 12 which is activated by the handset 2 when the handset 2 is placed thereon. It is being This switch means 1
2 is a handset 2 placed on the placing section 11, for example.
It is an automatic return type push switch that comes into contact with the

Furthermore, when the handset 2 is placed on the receiver 11, the radio body 5 is provided with a transmitter 13 of the handset 2.
A speaker 14 as a voice transmitting means facing the receiver 15 is provided, and a microphone 16 as a voice receiver facing the receiver 15 is provided.

As shown in FIGS. 3 and 4, the portable radio device 17 that transmits and receives data to and from the radio device body 5 has a microphone 18 as a transmitter and a speaker 19 as a receiver, similar to the handset 2. A switch 20 is installed to prevent interference and to perform transmission and reception with the radio main body 5.

This invention has the above structure, and its operation will now be explained based on the block diagram of FIG. 5.

Now, when a call is received and the ringing tone emitted from the telephone 1 is detected by the ringing tone detecting section 21 via the microphone 16 of the radio main body 5, this detecting section 21 causes the main transmitting section 22 to make a call. The sub-receiving section 23 and speaker 19 of the radio 17 inform the owner of the portable radio 17 that there is an incoming call. When the switch 20 is operated in order to respond to this call, a predetermined switch signal is transmitted from the sub transmitter 24 of the portable radio 17, received by the main receiver 25 of the radio main body 5, and the received signal is The signal is input to a switch signal detection section 26 which detects whether it is a switch signal or not. The detecting section 26 puts the main transmitting section 22, the speaker 14, and the movable means driving section 27 into an operating state only when the switch signal is included in the received signal of the main receiving section 25. When the drive section 27 operates, the solenoid 9 is energized and the switch 4 is raised, so that communication between the telephone 1 and the portable radio 17 via the radio main body 5 becomes possible.

Next, when the call ends, when the switch 20 is operated, the switch signal disappears, the switch signal detection section 26 puts the movable means drive section 27 into a non-operating state, lowers the switch 4, and the call is hung up. In FIG. 5, 28 is a bell inside the telephone 1. In FIG.

In addition, the handset 2 is placed on the mounting portion 11 of the radio main body 5.
If the movable means driving section 27 is operated by the switch means 12, the movable means driving section 27 can be used as before.

In the above embodiment, the switch signal may be one that issues a transmission start signal and a transmission end signal when the switch 20 is operated, and the switch 20 can select at least one of a plurality of radio device bodies. , a portable wireless device may be configured to allow calls to be made to multiple telephones.

Furthermore, although the movable means 8 moves the switch 4 that protrudes into the radio main body 5, the movable portion of the movable means 8 may be provided so as to be able to extend freely to the outside.

Furthermore, the radio device main body 5 and the portable radio device 17
may be provided with an antenna. The shape of the portable radio device 17 is not limited to that shown in FIGS. 3 and 4,
It may also be a combination of a headphone and a microphone. Furthermore, if the portable radio device 17 is used in a range where a telephone ringing tone can be heard, the ringing tone detection section 21 is not necessary.

As mentioned above, this invention allows you to answer telephone calls remotely by simply installing this device on an existing wired telephone.
Eliminates the hassle of having to go to the telephone installation location every time there is a call during work or the like.
