Description

  The present invention relates to a diving suit that allows easy adjustment of buoyancy.

There are wet suits and dry suits in diving suits. Wet suits themselves have no buoyancy adjustment function, and air is supplied to a buoyancy adjustment device (hereinafter referred to as BCD) to maintain neutral buoyancy in diving. The buoyancy was adjusted by exhausting. Moreover, since the dry suit wears underwear, it has a structure in which water does not enter the suit, and air can be supplied to and exhausted from the suit so that suit squeeze does not occur due to water pressure. However, in the case of a dry suit, since the entire suit is filled with air, it is difficult to achieve a balance, and BCD is used to adjust buoyancy.
For this reason, divers wear BCD in addition to the air tank when they wear either suit, and especially after diving, BCD sucks water, so the weight burden for elderly people, women, children, etc. who do not have physical strength Was big.
In order to solve these problems, as a method of adjusting the buoyancy during diving, (Patent Document 1) states that “a pocket-type fixture that can insert a large number of weights and floats into each part of the outer surface of the diving suit. A diving suit with a buoyancy adjustment fitting characterized by providing a buoyancy adjustment fitting ”is disclosed, and (Patent Document 2) discloses a“ padded shoulder or chest buoyancy adjustment bag, a back buoyancy adjustment bag with air A diving suit that can perform a buoyancy adjusting device by taking in and out of the apparatus is disclosed.

Japanese Patent Laid-Open No. 4-108090 US Extract 2002/23283

However, the above conventional techniques have the following problems.
(1) The technology disclosed in (Patent Document 1) adjusts the buoyancy by inserting a float or a weight into the pockets arranged in each part of the diving suit. It is necessary to prepare a weight and a float for diving, and when inserting a weight or a float that has already been inserted into a specific pocket, it is difficult to balance because the buoyancy is not adjusted. There was a problem that it could not be done.
(2) The technology disclosed in (Patent Document 2) performs adjustment of buoyancy by gas with an air bag formed in a diving suit, but since the buoyancy adjustment is controlled by a computer, the response after the operation is likely to be delayed. As the buoyancy adjustment bags are only formed on the chest, shoulders, and back, only the upper body is easy to float, the underwater posture is difficult to be leveled, and water resistance is received. In addition to being easy, when the air bag portion is damaged due to an external stimulus or the like, there is a problem that buoyancy cannot be adjusted and safety may be impaired.

  The present invention solves the above-described conventional problems, and can easily adjust the buoyancy without changing the posture during underwater diving, and can easily turn the posture underwater horizontally, and needs to wear a BCD. Because there is no BCD, there is no sense of weight and restraint of the equipment, BCD does not get in the way, you can diving comfortably regardless of age and sex, and you can work without wearing BCD Even divers in the agency can secure buoyancy to show their face on the surface of the water, adjust the buoyancy in the water, improve work efficiency and safety, and do not require BCD.

Hereinafter, the present invention will be specifically described by way of examples. The present invention is not limited to these examples.
Example 1
A diving suit similar to the diving suit of the first embodiment and an air tank with a capacity of 12 L were prepared. The tank was connected with a diving suit air supply valve, and in May 2012, it dived from 5m to 30m in Cebu Island, Philippines, and performed scuba diving for a total of 4 hours 30 minutes.
As a result, on land, there was no problem in comfort and it was the same as a general diving suit.
On the surface of the water, air was supplied to ensure buoyancy, but the buoyancy was sufficient to hold the upper part from the neck to the surface of the water although the chest expanded.
In addition, underwater, exhaust could be performed smoothly even when submerged, and air supply / exhaust was repeated as the depth changed, but the diver's requirements could be met without problems.
Therefore, unlike the scuba diving using the BCD, the diving suit of the first embodiment does not have the burden of weight and the feeling of restraint due to the use of the BCD, and can adjust the buoyancy in the same manner as the BCD. When moving underwater, the resistance of water was reduced and it was possible to move comfortably.
Also, the equipment could be reduced by the amount of BCD when transporting the equipment, and the time and labor for assembling the tank and BCD could be saved in preparation before diving.

  The present invention can easily adjust the buoyancy without changing the posture while diving in the water, and it is not necessary to wear the BCD. In addition, each configuration of the BCD does not get in the way, and it is possible to diving comfortably regardless of age or gender, and it is easy to adjust the buoyancy even for divers of the Japan Coast Guard who work without wearing the BCD. The working efficiency and safety can be improved, and since a BCD is not necessary, equipment required for scuba diving is reduced, and a diving suit capable of reducing the total weight during transportation can be provided.
