Fully shrouded self-rescue inflatable boat

Abstract

A fully shrouded self-rescue inflatable boat has a domed inflatable shroud, with a hollow air chamber formed for air inflation. A non-return inflation inlet is connected with the chamber. A waterproof bottom is mated at the bottom of the shroud, and a user space is defined between the shroud and bottom. An access hole with removable cover allows for access. A viewing window is arranged at the head end of the shroud in a waterproofing state. A puffing port protruded into the inner side of the head end of the shroud is connected with the chamber, helping the users in air inflation. A cold proofing lining is attached onto the inner surface of the shroud and bottom. Bulges for stretching out hands are set externally onto two lateral portions of the shroud, and configured into an elongated flexible waterproofing sleeve, enabling the users to stretch their hands out.

1 . A fully shrouded self-rescue inflatable boat, comprising:
 a domed inflatable shroud, with its cross section protruded into a domed pattern, and extended longitudinally to define a head end, a tail end and two lateral portions; the inflatable shroud is externally and internally coated by waterproof adhesive film; a sign for help is set externally onto the inflatable shroud, and a hollow air chamber formed internally for air inflation;   at least a hook, connected to at least one part of the inflatable shroud;   a non-return inflation inlet, set at one position of the inflatable shroud for air inflation; the non-return inflation inlet is connected with the hollow air chamber, allowing to prevent leakage of charged air;   a waterproof bottom, mated at the bottom of the inflatable shroud; the perimeter of the waterproof bottom is incorporated with the perimeter of the head end, tail end and lateral portions of the inflatable shroud into a waterproofing state; then a user space capable of accommodating a single person is defined between the inflatable shroud and waterproof bottom;   an access hole with removable cover, set at a domed area of the inflatable shroud, with an accessible aperture for an adult; the removable cover is assembled onto the access hole, enabling users to open or close the access hole;   a viewing window, arranged at the head end of the inflatable shroud in a waterproofing state; said viewing window is made of transparent materials for viewing by the users;   a puffing port, protruded into the inner side of the head end of the inflatable shroud; the puffing port is connected with the hollow air chamber, helping the users in air inflation;   a cold proofing lining, attached onto inner surface of the inflatable shroud and waterproof bottom; the cold proofing lining is made of insulating fabrics;   two bulges for stretching out hands, set externally onto two lateral portions of the inflatable shroud; the bulges for stretching out hands are designed into an elongated flexible waterproofing sleeve, enabling the users to stretch their hands out of the inflatable shroud.   
     
     
         2 . The structure defined in  claim 1 , wherein said removable cover is fitted with a ventilating and rainwater collecting portion, allowing external air to flow into the user space and collect rainwater; and a controlling portion is set at bottom of the ventilating and rainwater collecting portion, allowing the users to control the opening or closing state or level. 
     
     
         3 . The structure defined in  claim 1 , wherein an air generator is assembled onto the inflatable shroud; the air outlet of the air generator is connected with the non-return inflation inlet; the air generator is provided with a trigger, permitting to control and start the air generator for charging the hollow air chamber of the inflatable shroud. 
     
     
         4 . The structure defined in  claim 1 , wherein the inflatable shroud and waterproof bottom are coated with a fish repellent. 
     
     
         5 . The structure defined in  claim 1 , wherein the hollow air chamber of the inflatable shroud includes a plurality of spacers, such that the hollow air chamber is segregated into several spaces. 
     
     
         6 . The structure defined in  claim 1 , wherein a plurality of auxiliary storing buoys is configured at inner side of the connection between the lateral portions of the inflatable shroud and waterproof bottom; the auxiliary storing buoy is made of buoyant materials and designed into a hollow cylinder, a cover plate is set at one side of the auxiliary storing buoy facing the user space; said cover plate can be opened or closed flexibly.
