Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a flash light device for divers that is used as a beacon light indicating the position of a diver underwater or below the water surface, or as an emergency signal light.

(Prior Art) In order to indicate their position or to attract the attention of others, scuba diving divers use
The grip end of the knife hits the air tank hard, producing a warning sound. Furthermore, if an underwater light or the like is carried, it may be possible to display the location and draw the attention of others by making the underwater light blink by one's own operation.

(Problem that the invention aims to solve) Incidentally, in recent years, skiuba diving has become popular as a sport, and there are many technically inexperienced divers. Therefore, especially when diving in water with poor transparency, it is desirable for divers to be able to confirm each other's positions. However, it is not practical to constantly generate a warning sound during a dive using conventional means for generating a sound by hitting an air tank. Illumination by an underwater light cannot be recognized by other divers if the direction of the light beam is shifted due to the directivity of the underwater light.

Furthermore, it is not possible to confirm the position of a diver under the water from above the water using conventional means.

The present invention was developed in view of the above-mentioned circumstances, and is a flashlight for divers that flashes a high-intensity light while floating underwater or on the surface of the water to display the diver's position or notify them of the occurrence of an emergency situation. The purpose of the present invention is to provide a tsushiyu light device.

(Means for Solving the Problems) In order to achieve the above object, the flash light device for divers of the present invention includes a xenon lamp, a driving power source, and a flashing light from the xenon lamp in a floating case having a watertight structure. a blinking drive circuit, the specific gravity of the floating case is less than 1 in this stored state, a side wall of the floating case facing the xenon lamp is formed of a transparent member, and the floating case is separably connected to the main body case. At the same time,
The floating case and the main body case are connected by a rope, and a winding mechanism for the rope is provided on the main body case.

The main body case is provided with a release button which allows the rope to be let out when pressed against the elasticity of the spring, and which stops the rope from being fed out by pinching the rope with the elasticity of the spring when the pressure is released. It may be configured.

(Function) When a diver attaches the main case to his upper arm, etc. and drives the flashing drive circuit underwater to separate the flotation case from the main case, the flotation case floats above the diver by the length of the rope and displays high brightness. Emit flashing light. Then, the high-intensity light is radiated in all directions without being blocked by the diver's body. Furthermore, if the length of the rope is sufficient and the flotation case floats on the water surface, high-intensity light will be emitted on the water surface.

If a release button is provided to stop the rope from being fed out, the length of the rope to be fed out can be set arbitrarily, and the flotation case can be floated several meters above the diver or on the water surface.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a longitudinal cross-sectional view of an embodiment of the flash light device for divers of the present invention, FIG. 2 is an external perspective view of the device shown in FIG. 1, and FIG. FIG. 4 is a vertical sectional view showing a state in which the floating case is separated in FIG. 1 and the rope is stopped midway in being fed out; teeth,
It is a circuit diagram of an example used in the flash light device for divers of this invention.

1 to 4, the flashlight device for divers of the present invention consists of a flotation case 1 and a main case 2 made of a pressure- and impact-resistant resin material such as polycarbonate, and is suitable for skiuba diving. It is designed to be small and lightweight so that it is easy for divers to carry. The floating case 1 has a substantially spherical shape and is divided into two upper and lower parts from the center, and can be opened and closed by a screw structure, and is assembled into a watertight structure by sandwiching the packing 3 in the closed state. Further, the upper half of the floating case 1, which is divided into two parts, is made of transparent resin. The inside of the floating case 1 is divided into an upper space and a lower space by a reflector 4, a xenon lamp 5 is arranged in the upper space, and a battery 6 and a circuit board 7 as a driving power source are arranged in the lower space.
is stored. Further, a power switch 8 is provided in the lower half of the floating case 1, which is divided into two parts, and a locking claw 9 is provided to protrude downward. The power switch 8 is configured such that, for example, an operation part that can be slid freely outside the case is equipped with a magnet, and a reed switch provided inside the watertight structure is turned on or off depending on the position of the magnet of this operation part. be done. As mentioned above, floating case 1 is
It is designed so that the specific gravity is less than 1 when the xenon lamp 5, battery 6, circuit board 7, etc. are housed. That is, the flotation case 1 is designed to float on water.

Further, the main body case 2 has an insertion hole 10 in the upper surface into which the locking claw 9 of the floating case 1 is inserted, and the locking claw 9 inserted into the insertion hole 10 engages the locking hole 12 of the release button 11. penetrate. The release button 11 is elastically biased by a spring 13 in the direction of protruding outward from the main body case 2, and the locking claw 9 is locked and fixed by the edge of the locking hole 12. Furthermore, main body case 2
The ends of the locking claws 9 of the floating case 1 are connected with a thin and strong rope 14, and the main case 2 is provided with a winding mechanism 15 for winding one end of the rope 14. In addition, the main body case 2 is provided with a belt hole 16 so that it can be worn on a diver's upper arm or the like with a belt, and drain holes 17, 17 at the bottom.
is provided.

Next, the circuit will be briefly explained based on FIG. A known flash light circuit 20 as a flash drive circuit is mounted on the circuit board 7.
In this flash light circuit 20, when the power switch 8 is in the ON state, self-oscillation is performed by the transistor 21 and the transformer 22 using the voltage of the battery 6, and the pulsating current voltage generated in the transformer 22 due to this oscillation is The voltage is boosted to a high voltage by a single-turn step-up transformer 23. Furthermore, the boosted high voltage is applied to diode 2.
4 and smoothed by a capacitor 25, and the DC high voltage is applied to both electrodes of the xenon lamp 5. In addition, current is intermittently passed through the trigger step-up transformer 29 by a time constant circuit of the resistor 26, capacitor 27, and Zener diode 28 to which a high DC voltage is applied, and a high voltage is applied to the discharge ring 30 of the xenon lamp 5. High-intensity light is flashed from the xenon lamp 5. Note that in place of the Zener diode 28, a two-terminal thyristor or diak that breaks over at a predetermined voltage may be used.

According to this configuration, first, the locking claw 9 of the floating case 1 is inserted into the insertion hole 10 of the main body case 2, and is locked and fixed with the release button 11. Here, the rope 14 is in a state of being wound up by the winding mechanism 15.
Then, the main body case 2 is appropriately attached to the diver's upper arm or the like.

When one wishes to inform other divers of his/her position underwater, the power switch 8 is turned on to cause the xenon lamp 5 to flash with high brightness light.
Furthermore, the release button 11 is pressed against the elastic force of the spring 13 to close the locking hole 12 of the release button 11.
The floating case 1 has a specific gravity of less than 1, and the floating case 1 is pulled by the buoyancy of the winding mechanism 1.
The rope 14 is let out from the release button 11 when the rope 14 is released by a few meters.
When the pressure is released, the release button 11 moves in the protruding direction due to the elasticity of the spring 13, and the rope 14 is clamped between the edge of the locking hole 12 and the edge of the insertion hole 10 of the main case 2, stopping the payout of the rope 14. Therefore, the floating case 1, which emits a flashing high-brightness light, floats several meters above the diver, and the flashing high-brightness light is emitted in all directions without being blocked by the diver's body. This flashing light alerts other divers, and the position of the diver wearing this device can be recognized with certainty.

Furthermore, if all the ropes 14 are let out to float the flotation case 1 on the water surface, a high-intensity light flashes on and off on the water surface, and it can be easily confirmed from the water that a diver is swimming below the water surface.

In addition, in the above explanation, flashing flashing of high-intensity light is
This device was used as a beacon light to make it easier for others to confirm the location of the diver wearing it, but if the diver wearing it were to emit flashing high-intensity light in the event of an unexpected emergency, this device could can be used as an emergency signal light.

(Effects of the invention) The flashlight device for divers of the invention has the following features:
Since the configuration is as described above, the following effects can be achieved.

In the flashlight device for divers according to claim 1, the high-intensity light flashes on and off above the diver by the length of the rope, so that the high-intensity light is emitted in all directions without being blocked by the diver's body. Ru. Therefore, the position of the diver wearing the device can be confirmed from all sides. Furthermore, if the length of the rope is sufficient and the flotation case is floated on the water surface, a high-intensity light flashes on and off on the water surface, making it easy to confirm from above the water that a diver is swimming below the water surface.

In the flash light device for divers according to claim 2, since the length of the rope to be let out can be set arbitrarily, the flotation case can be floated several meters above the diver or floated on the water surface, depending on the situation and purpose. You can select the position of the floating case.
