 The present invention relates to a levitation guide device for night time, and more particularly to a device for guiding a diver at a constant ascending speed while emitting light when the diver floats from the water surface toward the water surface at night. .

[0002]

[Prior art]

 As is well known, people often dive into water. At the same time, when diving, the surface of a diving person is required to ascend at a certain ascending speed when ascending toward the surface of the water. This is because the diver must gradually discharge the nitrogen gas accumulated in the body out of the body in the water.

The levitation speed for satisfactorily discharging the nitrogen gas accumulated in the body of the above-mentioned diver to the outside of the body is generally about 10 mm to 18 mm per minute.

Further, in order to exhaust the nitrogen gas accumulated in the body to the outside of the body more completely, it is strongly encouraged for the diver to stop at a predetermined depth position for a predetermined time and then resurface again. The stop position and stop time of the above-mentioned diver are generally about 5 m in depth and about 3 minutes, respectively.

Further, conventionally, there has been a demand for means for allowing the above diving person to ascend at a constant ascent speed and to be surely stationary at a predetermined depth position.

[0006] Therefore, the present applicant has previously shown a floating guide device in Japanese Patent Application No. 5-191973. More specifically, in a levitation guide device including an outer die part forming the levitation guide device body and a hollow part formed inside the outer die part 2, the outer die part 2 forming the levitation guide device body. Is made of a hard material whose volume of the hollow portion does not change, forms the closed space of the hollow portion, and is attachable to and detachable from one end of the outer die portion at one end of the outer die portion. A levitation guide device characterized in that a balance member for changing the weight is attached.

Then, the usage is to attach a balance member to the main body of the levitation guide device and separate the entire levitation guide device in water. As a result, the levitation guide device ascends at a constant levitation speed, and the diver is guided by the levitation guide device and ascends. Further, if the underwater stopping balance member is attached to the main body of the levitation guide device during the levitation, the entire levitation guide device stops in the water. As a result, the diving person himself / herself stops at the predetermined water depth position, aiming at the suspended guiding device.

[Problems to be solved by the device]

 According to the above-mentioned conventional technique, it is possible to guide the diving person to the water surface at a constant ascending speed, and it also serves as a target for stopping the diving person at a predetermined depth position.

However, there are problems in the following points. That is, the diving into the water is often performed not only in the daytime but also at night. When the above-mentioned conventional levitation guide device is used during such nighttime diving, it is extremely difficult to visually confirm and target the above-mentioned conventional levitation guide device in the dark. As one method, there is also a method of levitation while illuminating the light to the levitation guide device, but it is also difficult for the diver himself to levitation while illuminating the moving levitation guide device. The action of illuminating is also very elaborate, and it also makes the diver use extra nerves.

Therefore, the object of the present invention is to guide the diving person at a constant ascending velocity when the diving person moves up from the water toward the water surface, and also to stop the diving person at a predetermined depth position. It is not only a levitation guide device that enables the person to stop at that position, but also, especially when diving at night, when the diver uses the levitation guide device, make sure to confirm the above-mentioned levitation device.
