Description

[Detailed Description of the Invention] The present invention provides a netless antenna that can be used as a transmitting antenna in advance when an elderly person living alone, a sickly person, etc. suddenly becomes ill.
A radio-controlled emergency call device that operates the transmitter by pulling the transmitter, which is always attached to the chest or wrist using an arm band, etc., from a net dress, arm band, etc., and sends out emergency radio waves to make an emergency call. This invention relates to a transmitting device with a completely waterproof mechanism.

As explained in detail in the applicant's earlier application, Japanese Patent Application No. 56-027123 ``Emergency Call Device'', the effect can be expected by always wearing a highly reliable transmitting device on the body. However, there are situations where it can be activated anytime and anywhere, such as when someone is taking a bath or washing their body in a bathroom, and the transmitter is equipped with a completely waterproof mechanism. Without it, it would be useless. For installing built-in devices or replacing batteries, etc.
The waterproofing mechanism of the lid is quite simple and common sense, such as interposing a packing made of rubber or plastic and closing the lid with screws, but it is necessary to pull the transmitter body from the netsukuresu, which is a rough operation during a sudden illness attack. The waterproof mechanism of the transmitting power switch, which closes completely when the switch is closed, has a movable part on the outside that is mechanically connected to the internal switch, so it is difficult to expect complete waterproofing other than covering the movable part with a rubber or plastic membrane. However, it is difficult to say that it is perfect as it gets damaged and deteriorates over many years. Moreover, it is aesthetically unsightly, and it is difficult to create a completely waterproof mechanism that is highly reliable, can withstand long-term use, and has a good aesthetic appearance. This means that
I think you can understand the waterproof mechanism of a waterproof flashlight switch.

Here, the present invention uses a reed switch as an internal power switch, and brings a permanent magnet from an isolated outside close to or away from a partition wall that the internal reed switch is in contact with. This purpose is achieved by opening and closing a reed switch using the magnetic force of a permanent magnet, and this completely satisfies the requirements of complete waterproofing, high reliability, long life, and aesthetics. be. Hereinafter, the structure, operation, effects, etc. of the embodiment will be explained in detail with reference to the accompanying drawings.

FIG. 1 is a three-dimensional perspective view of an embodiment of a netskure pendant type transmitting device according to the present invention, with a part cut away to show the inside. 1 is a transmitting device made of non-magnetic metal, plastic, etc. The main body of the device, 2 is a reed switch with an offset type break contact (hereinafter simply referred to as the break reed switch), and 3 is a cylindrical permanent magnet with a round tip and an annular groove for a click stop, which is installed inside. Although it is not visible in the figure, the break lead switch 2, which is not visible in the figure, and the power supply battery, transmitter, etc. are connected to a cylindrical blind hole made of non-magnetic metal or plastic and isolated from the inside in an airtight and waterproof manner, as shown by the hatched cross section. Once inserted, the switch is click-stopped by a click-stop ball 10 and a spring 11, and the break lead switch 2, which is provided circumscribed outside the cylindrical blind, is opened by this magnetic force. 6 is a transmitting antenna terminal provided with a neckless connection ring. Reference numeral 8 indicates a neckless which also serves as a transmitting antenna, and a fragmentation symbol 12 indicates that the neckless is long. 7 indicates the other end of the netcress, which is mechanically connected to the permanent magnet 3 by a connecting ring provided on the top of the permanent magnet 3. The netcress 8 is hung around the neck and the transmitting device main body 1, which is suspended from the chest, is connected with the hands and fingers. The pulling action releases the click stop on the permanent magnet 3, and the permanent magnet 3 comes out of the cylindrical blind hole. At the same time, the magnetic force is removed, so the break reed switch 2 is restored and closed, and current is removed from the power battery. is supplied, the transmitter starts operating, and emergency radio waves are sent out from Netsukuresu. As shown in the figure, the permanent magnet 3 inserted into the transmitting device that is on standby is apparently located inside the transmitting device main body 1, but in terms of airtightness and waterproofing, it is located outside, separated from the internal device. The waterproofing of the internal equipment is complete. In addition, in the embodiment shown in Fig. 1, a break type reed switch is used, but it is also possible to achieve the purpose by using an ordinary make type reed switch. The correlation between switches is shown in Figure 3.
It is shown in FIG. 4 and will be described later.

FIG. 2 is a three-dimensional perspective view of an embodiment of a wristwatch-type transmitting device according to the present invention, and the numbers with dashes correspond to the numbers shown in FIG. 1, although they are deformed. It is shown that. That is, 1' is the main body of the transmitter, 2' shown by the reference line is a break lead switch, 3' is a cylindrical permanent magnet, 10' is a ball for the click stop of the permanent magnet 3', and 8' is also used as a transmitting antenna. The arm band 6' is an arm band connection ring that also serves as a transmitting antenna terminal.
7' is the end of the arm band, and is provided with a cylindrical permanent magnet 3' having an annular groove for a click stop at the tip, and a protrusion 4 for holding the arm band, which also has an annular groove, and is provided on the transmitter body 1'. The clip stop is held by inserting it into two cylindrical blind holes, and it is permanently held by pulling the transmitter body 1' worn on the arm from the end 7' of the arm band with your fingers, mouth, etc. The magnet 3' and holding protrusion 4 are pulled out from the main body 1', and the break reed switch 2' is closed. The following operations are similar to those shown in FIG. 1, and the interrelationship structure with the internal power battery, transmitter, break lead switch, permanent magnet, cylindrical blind hole, etc. is also similar to that shown in FIG.

FIG. 3 is an explanatory diagram of the positional relationship between the break reed switch 2 and the permanent magnet 3, and the figure shows that the break contact is now opened by the magnetic force of the break reed switch 2 and the permanent magnet 3 adjacent to it. There is. When the permanent magnet 3 is moved in the direction of the arrow A and reaches the 3'' position, the magnetic force no longer acts on the break reed switch 2, so the break contact is restored and closed. Therefore, FIGS. 1 and 2 In the transmitter of the embodiment shown in Fig. 1, when the permanent magnet 3 or 3' is inserted into the cylindrical blind hole to the position where it clicks, the break reed switch 2 or 2' is opened by the action of the magnetic force and pulled out. The contacts are closed, current is supplied to the built-in transmitter, and emergency radio waves are sent out.

FIG. 4 is an explanatory diagram of the positional relationship between the normal make-lead switch 5 and the permanent magnet 9. At the current position in the figure, the magnetic force of the permanent magnet 9 is not sufficient to operate the make-lead switch 5, so the make contact is is open. When the permanent magnet 9 is moved in the direction of the arrow A and reaches the position 9', the make-read switch 5 is closed by the action of magnetic force. When the switch is further moved to the 9'' position, the magnetic force is insufficient to hold the contacts closed, and the make-lead switch 5 is opened. To operate the transmitter using the permanent magnet 9
By moving the switch from the current position to the 9' position, the contact can be closed and the device can be operated, but the make contact cannot be closed at any position other than 9', so the embodiment using a make lead switch Since the permanent magnet cannot be pulled out from the cylindrical blind hole in which the permanent magnet is inserted, a retaining mechanism at the 9' position is required. There is also the possibility that the transmitter may be cut off or the clasp mechanism may be damaged and the transmitter may stop operating. In other words, it can be said to be inappropriate for handling in rough motions. Therefore, it can be said that a device operated by using a break reed switch and pulling out the permanent magnet is more reliable. In addition, reed switches use gold or rhodium as the contact material and are filled with inert gas, and the moving parts are completely protected by a glass tube, so they have a long life and are extremely reliable. It's expensive. In addition, by using a lithium battery as the power source, if tests and malfunctions are eliminated, it can last for up to 7 years, or as short as 4 to 5 years.
Since it can be kept on standby for a year, and the transmitter has a simple structure and low manufacturing costs, it can be used as a disposable transmitter when the battery is replaced by using a plastic mold construction method. As an example, we produced a prototype in which the main body and internal built-in parts are integrally molded, and this is a completely airtight and waterproof mechanism, and has advantages such as lower manufacturing costs, improved aesthetics, miniaturization, and suitability for mass production. produce. Internal built-in parts to be integrated include a lithium battery for power supply, a transmitter, a reed switch, etc. In this case, there is a cylindrical blind adjacent to the reed switch into which a cylindrical permanent magnet is inserted. It goes without saying that you should make use of the holes.

As detailed above, the transmitting device with a completely waterproof mechanism in the radio-controlled emergency notification device according to the present invention has outstanding characteristics such as being completely waterproof, highly reliable, and long-life, and also has a good appearance. Users of this device can wear the device without taking it off their body, even while taking a bath, so it is possible to have it activated and on standby 24/7 in case of sudden illness attacks. It is extremely large.
