Abstract
Official abstract text for this publication.
The present invention relates to a decompression buoy ( 1 ) comprising an inflatable bag ( 2 ) having a tubular portion ( 4 ) defining a an inside volume ( 12 ) and a longitudinal opening portion ( 6 ) with a first end ( 14 ) leading to the inside volume ( 12 ) and a second end ( 16 ) leading to the outside. The opening portion ( 6 ) thus enables gas to flow between the outside and the inside volume ( 12 ). The opening portion ( 6 ) includes a throat ( 18 ) of transverse dimension that is smaller than the transverse dimension of the first end ( 14 ), and the second end ( 16 ) is adapted to receive the end of a diving regulator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A decompression buoy comprising: an inflatable bag having a tubular portion defining an inside volume and an opening portion with a first end leading to the inside volume and a second end leading to an outside, the opening portion thus enabling gas to flow between the outside and the inside volume, wherein the opening portion includes a throat of transverse dimension that is smaller than a transverse dimension of the first end and a transverse dimension of the second end, and wherein the opening portion also includes, between the first end and the throat, a first fraction converging towards the throat from the first end; and a line mounted on the opening portion of the inflatable bag. 2. The decompression buoy according to claim 1 , wherein the opening portion does not have any mechanical closure fitted thereto. 3. The decompression buoy according to claim 1 , wherein the transverse dimension of the first end is substantially equal to the transverse dimension of the second end of the opening portion. 4. The decompression buoy according to claim 1 , wherein the first fraction extends over a length lying in a range 0.5 to 2 times the transverse dimension of the first end. 5. The decompression buoy according to claim 1 , wherein the opening portion also includes, between the second end and the throat, a second fraction that diverges from the throat towards the second end. 6. The decompression buoy according to claim 1 , wherein the tubular portion of the inflatable bag is cylindrical in shape, with a transverse dimension that is substantially constant. 7. The decompression buoy according to claim 6 , wherein the transverse dimension of the tubular portion is substantially equal to the transverse dimension of the first end. 8. The decompression buoy according to claim 1 , wherein the line is mounted on the inflatable bag between the throat and the second end of the opening portion. 9. A decompression buoy comprising: an inflatable bag having a tubular portion defining an inside volume and an opening portion with a first end leading to the inside volume and a second end leading to an outside, the opening portion thus enabling gas to flow between the outside and the inside volume, wherein the opening portion includes a throat of transverse dimension that is smaller than a transverse dimension of the first end and a transverse dimension of the second end; and a line mounted on the opening portion of the inflatable bag, between the throat and the second end of the opening portion.
