JP3011332U - Airbag frame type salvage buoy - Google Patents

Abstract

(57) [Summary] A salvage buoy that becomes a three-dimensional body by filling a skeleton made of air bags with gas. [Purpose] Conventionally, there was a lack of practicality because it was too thin to be seen from a distance, and the air chamber (2) was too large and required a large amount of gas. Therefore, a smaller amount of gas is used to expand the gas. [Structure] An air chamber (2) is formed in a side portion of a polyhedron made of a synthetic resin curtain (1), and only the air chamber (2) is filled with gas to inflate the polyhedron. The polyhedron is also provided with a mounting part (4) such as a string for connecting the polyhedron to the body.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a salvage buoy that can maintain a three-dimensional shape by filling gas only in the parts corresponding to the sides of the polyhedron made of synthetic resin curtain (1).

[0002]

[Prior art]

 Previously, there was a single straight vinyl tube or a large polyethylene bag.

[0003]

[Problems that the device is trying to solve]

 These had the following drawbacks. (A) Because it is thin, it is difficult to see from a distance, and when the wind is strong it bends and becomes more difficult to see. (B) A large amount of gas was required because of the structure that allows gas to enter the whole.

[0004]

[Means for solving the problem]

 When making a polyhedron with a synthetic resin curtain (1), create air chambers (2) at the parts corresponding to the sides, connect each air chamber (2), and remove the gas from one filling port (3). Allow all air chambers (2) to expand by filling.

[0005]

[Action]

 In this way, a small amount of gas can be made larger, visible from a distance, and structurally strong.

[0006]

【Example】

 Embodiments of the present invention will be described below. (A) Provide air chambers (2) on the sides of the polyhedron so that the air chambers (2) are connected. (B) A filling port (3) for filling the air chamber (2) with gas is provided at the top of the polyhedron. (C) A portion (4) for connecting a string or a band is provided near the filling port (3).

(A) The present invention has the above-described structure. When using the present invention, the cord or band is tied to a part of the body or peripheral equipment, and then the cylinder is inserted from the filling port (3). And so on. After filling, fold the filling port (3) and fix it with tape to prevent gas from leaking. (B) In order to create the air chamber (2), in addition to the method of making the polyhedron together, as shown in FIG. 3, a tube (5) made of a synthetic resin curtain is used to form the polyhedron skeleton in advance. It is possible to make a polyhedron by making 2) and then lining the air chamber (2) with a synthetic resin curtain (1). In either case, it is important that the entire air chamber (2) be inflated by filling the gas from one location. (C) Depending on the material of the synthetic resin, it can be used with various durability, from one that can be used several times to one-time disposable. (D) If you use helium gas for a light material, you can levitate several meters above the sea surface. (E) Depending on the color and paint of the synthetic resin, it can be very noticeable or can reflect sunlight.

【effect】

 The use of this product by victims at sea would greatly increase the probability of being found in rescue vessels and aircraft. Moreover, with this structure, the size when folded up is such that it fits in a pocket, so there is no hindrance even if you equip yourself with a scuba diver.
