Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention turns on a light source such as a lamp, emits a signal (SOS), or turns on a light source by putting it in water at the time of an accident or the like. In addition, the present invention relates to an emergency notification device that transmits a signal and notifies the position thereof.

<Prior Art> As a conventional notification device at the time of a distress, there are the following devices.

(A) One of them is that a light source such as a lamp, a control circuit for controlling lighting, extinction and blinking of the light source, and a power source such as a battery for operating the light source and the control circuit are incorporated in a floating body having buoyancy. Device. Then, at the time of use, the light source and the control circuit are put into the water after turning on the switch of the power source.

(B) The other one is a device in which a light source such as a lamp, a floating body provided with a magnet, a reed switch arranged in the vicinity of the floating body, and a power source for the light source are incorporated in a floating cylinder having buoyancy. Is. In use, when the floating cylinder is put into water, the floating body floats and the reed switch is closed by the magnet to apply power to the light source and turn on the light source.

(C) Still another one is a device including a signal smoke emitting tube, a resistance wire for igniting the smoke emitting tube, a seawater battery for heating the resistance wire, and the like in a floating body having buoyancy.
Then, when the floating body is put into the sea, the seawater battery causes a chemical change with the seawater to generate electricity and smoke the smoke tube.

<Problems to be Solved by the Invention> However, in the above device (a), since it is necessary to turn on the power switch before the floating body is put into seawater, the operator forgets, stretches, or operates. If the switch is not turned on due to inability, the device will not operate.

Further, in the device using the above-mentioned (b) magnet-attached floating body,
On land, for example, there is a drawback that the floating body moves during transportation and carelessly closes the reed switch to turn on the light source.

Further, in the device using the seawater battery of the above (c), since the seawater battery generates power only by a chemical change with seawater, there is a drawback that the seawater battery does not operate in fresh water such as lake water and rivers.

The present invention has been made in view of the above points, and one of the objects of the present invention is to automatically close the power supply circuit when it is put into water regardless of seawater or fresh water. Another object of the present invention is to provide an emergency notification device for the purpose of easy operation and certainty of operation.

One of the objects of the present invention is to provide an emergency notification device that does not operate even if it is accidentally sprayed with rain, for example, while being carried in the rain.

Another object of the present invention is to provide an emergency notification device that can also be used as a Morse coder.

Another object of the present invention is to provide an emergency notification device that can facilitate the discovery of a target even at night.

<Means for Solving the Problem> In order to achieve the above object, the emergency notification device according to the present invention is a floating body having buoyancy, a power source housed in the floating body, and an on-hold type switching element. An alarm connected to the power source and a pair of switch terminals arranged so that one end thereof is exposed to the outside of the floating body are provided, and one electrode of the power source is connected to the one switch terminal. Along with the other switch terminal, the switching element is connected, and when the both switch terminals are short-circuited with water, in the portable emergency notification device configured to conduct the switching element, the both switch terminals are It is constructed so that it is exposed to the outside of the floating cylinder from the locations partitioned by partition walls, and an appropriate part of the floating cylinder is operated from the outside to open and close the circuit of the power supply. It is characterized in that comprising mounting a power switch configured to so that.

And as the above-mentioned notification device, a light source, a transmitter, or a combination of both is adopted.

Further, there is also one in which the light emitting portion of the phosphorescent pigment and the light emitting portion of the retroreflective structure are appropriately distributed on the outer peripheral surface of the floating cylinder.

<Operation> The present invention is configured as described above. Next, the operation will be described.

When the floating body is put into water, both switch terminals are short-circuited with water as a conductor, so that the positive voltage of the power source is applied to the ON-holding type switching element through the resistance. Therefore, since the switching element is in a conductive state, the alarm device operates (lights up, transmits, etc.). Then, once the current flows, even if the floating body is lifted from the water and the voltage from the switch terminal side disappears, the switching element continues to be in the conductive state (on), so that the alarm continues to operate. The operation of this alarm can be stopped by turning off the power switch.

Further, even if, for example, rain blows on the floating body to wet the exposed ends of both switch terminals, the partition walls do not short-circuit both switch terminals using the rainwater as a conductor. Since the switching element does not conduct, the alarm does not work.

Furthermore, when both switch terminals are connected by a lead wire, they are applied to the switching element, become conductive, operate the alarm, and turn on the light source such as a lamp. Therefore, in this state, the power switch can be turned on and off to open and close the power circuit to use it as a Morse code.

Furthermore, in the case where the light emitting portion of the phosphorescent pigment and the light emitting portion of the retroreflective structure are distributed on the outer peripheral surface of the floating tube, when the floating tube is irradiated with light, the The light emitting portion of the reflective structure reflects and emits light, and when the light is moved away from the floating body, the light emitting portion of the phosphorescent pigment emits light. That is, according to the present invention, the floating body emits light while radiating light from the outside and also emits light when the light is moved away. Therefore, it becomes easy to find the floating body even at night.

The lid 3 is hermetically screwed to the upper end of the opening of the body 2 with a packing 4 and the like interposed. There is a case where a light emitting portion of a phosphorescent pigment and a light emitting portion of a retroreflective structure are formed on the outer peripheral surface of the body portion 2, and this point will be described later in detail.

Inside the floating body 1, a light reflection plate 5 is horizontally supported and fixed by a body 2 and a lid 3. A socket 6 is fixed to the center of the light reflection plate 5, and a light source 7 such as a lamp is inserted into the socket 6 so as not to come off due to vibration and is disposed inside the lid 3. Thus, in this embodiment, the light source 7 is adopted as the alarm.

Reference numeral 9 denotes a container that accommodates electronic parts such as an on-hold type switching element described below for controlling the light source 7 and the like. The container 9 is housed in an accommodation chamber 10 formed in the inner cylindrical body 8 with earthquake resistance. There is. 11a and 11b are switch terminals having good conductivity, and both switch terminals 11a and 11b are arranged opposite to each other so that one ends thereof are exposed to the outside of the body portion 2 of the floating body 1. In this case, the switch terminals 11a and 11b are configured to be exposed while maintaining airtightness. Both switch terminals 11a, 1
It is preferable to expose 1b to the lower side of the body 2.

Reference numeral 12 operates an alarm (light source 7 in this embodiment) and electronic parts. A power source such as a battery, the power source 12 is housed in a power source storage chamber 13 formed in the lower portion of the storage chamber 10.

An annular step portion 14 is formed on the lower portion side of the body portion 2 of the floating cylinder 1, and portions 16a and 16b defined by partition walls 15 are formed on the step portion 14 so as to face each other. There is. And
The one switch terminal 11a is from one location 16a, and the other switch terminal 11b is from the other location 16b.
It is configured to be exposed to the outside. This allows the step
Even if it is rained on 14, the partitions 16a and 16b are
Since they are separated by 15, both switch terminals 11a and 11b
Are not short-circuited. 17 and 17 are insertion holes such as strings.
A mounting body provided with an appropriate portion of the stepped portion 14 including the mounting body
17 is formed to attach a string 19 for attachment.

20 is the power source 12 by pressing the push button 21
The power switch is configured to open and close (ON, OFF) the contact interposed in the circuit of the power switch 20. The power switch 20 is arranged airtightly on the bottom side of the body 2, and the push button 21 is externally attached. The circuit of the power source 12 is opened and closed by pressing. A protective cap 23 for the power switch 20 is made of rubber or the like, and the cap 23 is fitted to the lower end of the body 2. The push button 21 is pressed from the outside of the cap 23.

FIG. 3 is a circuit diagram showing an embodiment of the device of the present invention, in which the on-hold type switching element 22 is interposed in the circuit of the power supply. The ON-holding type switching element 22 of the embodiment is composed of a thyristor, where A is an anode, K is a cathode, and G is a cathode.
Indicates a gate, the gate G of the thyristor 22 is connected to the one switch terminal 11b via the resistor R, and one pole (positive pole in the figure) of the power source is connected to the other switch terminal 11a.
It is connected to the.

The emergency notification device in this embodiment is configured as described above, and the usage method and operation thereof will be described below.

At the time of use, one end of a string 19 having one end fixed to the floating body 1 is locked to the life jacket of the user, or is locked to a lifeboat or other desired distressed object 24.

Therefore, in the event of a distress or the like, when the floating cylinder 1 is placed in water such as seawater or a river, the weight of the power supply 12 causes the floating cylinder 1 to float above the water surface 25 with the lower end side down, The body 3 projects from the water surface (see FIG. 5).

Then, the submerged switch terminals 11a and 11b are short-circuited by water, so that the positive voltage of the power source 12 is applied from the switch terminal 11b to the gate G of the thyristor (switch element 22) via the resistor R.

Therefore, the thyristor 22 becomes conductive and the power supply
Since the power supply 12 is applied to the 12 circuits, the light source 7 is turned on. Then, as described above, once the current flows,
Even if the gate voltage disappears, the thyristor maintains the conductive state, so that the light source 7 is turned on. Then, as described above, once the current flows, the thyristor maintains the conductive state even if the gate voltage disappears, so that the light source 7 continues to be turned on. As described above, after both switch terminals 11a and 11b are once submerged in water, the ON-holding type switching element keeps the ON state by itself even if it is taken out from the water.

The light source is turned off by operating the power switch 20 to turn off the power.

Next, another example of use is as follows. That is,
Both switch terminals 11a and 11b are connected by a suitable conductor.
As a result, the thyristor becomes conductive similarly to the above, and the light source 7 is turned on. Therefore, in this state, when the power switch 20 is externally pressed to open / close (ON / OFF) the contact of the switch 20, the light source blinks. Therefore, in this way, it can be used as a Morse code device.

Although the light source 7 such as a lamp is used as the alarm device in the embodiment, a transmitter that transmits a signal may be used instead of the light source as the alarm device, or the light source and the transmitter may be used. Both may be used together.

In the embodiment, the thyristor is used as the on-holding type switching element 22. However, the on-holding type switching element 22 is a combination of a thyristor and a transistor (Darlington circuit type, etc.). It may be configured by an object, an integrated circuit, or the like, and the point is that once it is in a conductive state (on), it can be self-maintained until the power is turned off.

FIG. 4 shows an embodiment in which the outer peripheral surface of the body 2 of the floating cylinder 1 is provided with light emitting properties. That is, in this embodiment, the light emitting portion A of the phosphorescent pigment and the light emitting portion B of the retroreflective structure are appropriately mixed and formed on the surface of the body 2.

The specific formation of both the light emitting portions A and B may be performed as follows, for example. That is, the light emitting portion A of the phosphorescent pigment is formed by applying the phosphorescent pigment to a predetermined portion of the body portion 2 with a brush, spraying it with a spray gun, or during the manufacturing process of the body portion 2 in the plastic powder raw material. Mix an appropriate amount of phosphorescent pigment powder (at this time, also mix an appropriate amount of antioxidant if desired), stir and mix this to make a raw material for the product, and mold this raw material by a known molding machine by a conventional method. To manufacture the body 2. As a result, the light emitting portion A of the phosphorescent pigment is formed on the entire surface of the manufactured body 2.

Then, the light emitting portion B of the retroreflective structure is formed by adhering glass powder onto a desired portion of the surface of the body portion 2 or by adhering a commercially available retroreflective sheet material. As a result, the light emitting portions A and B are appropriately distributed and formed on the surface of the body portion 2.

Other configurations and operations are exactly the same as in the above embodiment.

The emergency notification device of this embodiment is configured as described above, and the operation and the like will be described next.

When the light from the body portion 2 of the floating body 1 is irradiated, the light emitting portion B of the retroreflective structure reflects and emits light during this irradiation, and when the light is moved away from the body portion 2, the light emitting portion A of the phosphorescent pigment A Emits light. In this way, the body portion 2 emits light while irradiating light from the outside and also emits light after the light is moved away. Therefore, in combination with the function of the alarm device (light source 7 or the like), the floating cylinder can be easily found even at night.

Other functions are exactly the same as in the above embodiment, as described above.

<Effects of the Invention> According to the present invention, the following effects can be expected.

(1) Regardless of seawater or fresh water, when placed in water, the on-hold type switching element automatically becomes conductive to close the circuit of the power supply and drive the alarm.

(2) It can be used regardless of whether it is seawater or fresh water.

(3) When used, the operator does not need to operate at all, and when the floating body is put into water, the switch is automatically turned on to activate the alarm.

(4) Since the on-hold type switching element is used,
Once activated, the alarm continues to operate until the power switch is turned off.

(5) Since both switch terminals are configured to be exposed to the outside of the floating body from the locations partitioned by the partition walls, it is possible to prevent both switch terminals from being inadvertently short-circuited even if rain or the like is sprayed on the floating body. Can be prevented.

(6) By pressing the power switch with both switch terminals short-circuited by a conductor or the like, it can be used as a Morse code signal.

(7) In the case where the light emitting portion of the phosphorescent pigment and the light emitting portion of the retroreflective structure are appropriately distributed on the outer peripheral surface of the body portion, in combination with the function of the alarm device, even at night. The floating body can be easily found.
