Description

Strap buoyancy control device

The present invention relates to snorkeling and deep dive, and more particularly to the field of buoyancy control devices for snorkeling and deep dive, a scuba device, a method of assembling or manufacturing a buoyancy control device, and a kit of buoyancy control devices.

In many groups, there is a growing interest in snorkeling and deep dive. For most people, after several snorkelings in contact with the water, they will begin to have an interest in deep dive. Similarly, many deep dive They also like snorkeling, in shallow water (usually within 9m (29ft) deep), especially near seawalls, coral reefs and other rock formations, where you can see interesting marine life or other aquatic life at or near the bottom. For snorkelers, especially those who have also worked in deep dive, when they want to dive deeper to see more carefully, but they are limited by their ability to suffocate underwater, they will feel frustrated. sense.

Due to the positive buoyancy characteristics of snorkeling, the ability to swim down and maintain the depth of the water, the dive time under normal snorkeling under a deep breath will be less than the time the diver can hold the breath, at which time oxygen is consumed in the body. The speed is higher than when the body is at rest.

The snorkeling posture in the water is usually horizontal and face down.

When preparing for deep dive, wearing a buoyancy control device (BCD) of the prior art, it is difficult and uncomfortable to adopt a snorkeling posture, and the back-type gas cylinder based on its standard size is very heavy outside the water. The effect of this weight is sufficient to sink the diver, which in turn requires the BCD to have some buoyancy so that the diver can maintain on the surface of the water. Therefore, the prior art BCD cannot be applied to snorkeling.

The gas cylinder 51 is coupled to the D-ring 25 via a connecting rod 73 which is provided in the ring connecting member 69 (and the element 67 is connected to the D-ring 29)

This provides a lightweight and simple buoyancy control harness (BCH) 1, which further incorporates a small floating airbag and is designed with swimwear/swimwear, or with a moderate air supply 51, or A thin suit is usually used when snorkeling is performed using a breathing tube 63 on a warm water surface.

In other embodiments, the gas cylinder may include a single 5 liter reserve gas cylinder disposed in front of the diagonal or center, or two 5 or 7 liter cylinders 51.

The gas cylinder 51 is equipped with a first stage regulator 59, a second stage regulator 61 and an air bag connection member 33.

It is contemplated that the use of a secondary second stage breathing regulator (or octopus) device in the illustrated embodiment is not necessary for open water shallow layer characteristics unless more in-depth diving and considerations.

Further embodiments may include such regulators or octopus styles, but in the illustrated embodiment in an emergency where gas is short, the user may simply ascend to a short distance of the surface if they have been in a single deep breath Like diving, the difference is the need to exhale during ascent to prevent lung expansion and injury.

The present invention has been described with reference to the preferred embodiments thereof, and it is understood that variations and modifications can be made by those skilled in the art without departing from the scope of the invention.
